Albedo

Albedo (; ) is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. Surface albedo is defined as the ratio of radiosity Je to the irradiance Ee (flux per unit area) received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as obtained from flux measurements) to daily, monthly, or annual averages. Unless given for a specific wavelength (spectral albedo), albedo refers to the entire spectrum of solar radiation. Due to measurement constraints, it is often given for the spectrum in which most solar energy reaches the surface (between 0.3 and 3 μm). This spectrum includes visible light (0.4–0.7 μm), which explains why surfaces with a low albedo appear dark (e.g., trees absorb most radiation), whereas surfaces with a high albedo appear bright (e.g., snow reflects most radiation). Albedo is an important concept in climatology, astronomy, and environmental management (e.g., as part of the Leadership in Energy and Environmental Design (LEED) program for sustainable rating of buildings). The average albedo of the Earth from the upper atmosphere, its planetary albedo, is 30–35% because of cloud cover, but widely varies locally across the surface because of different geological and environmental features. The term albedo was introduced into optics by Johann Heinrich Lambert in his 1760 work Photometria. Terrestrial albedo Any albedo in visible light falls within a range of about 0.9 for fresh snow to about 0.04 for charcoal, one of the darkest substances. Deeply shadowed cavities can achieve an effective albedo approaching the zero of a black body. When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms. Most land areas are in an albedo range of 0.1 to 0.4. The average albedo of Earth is about 0.3. This is far higher than for the ocean primarily because of the contribution of clouds. Earth's surface albedo is regularly estimated via Earth observation satellite sensors such as NASA's MODIS instruments on board the Terra and Aqua satellites, and the CERES instrument on the Suomi NPP and JPSS. As the amount of reflected radiation is only measured for a single direction by satellite, not all directions, a mathematical model is used to translate a sample set of satellite reflectance measurements into estimates of directional-hemispherical reflectance and bi-hemispherical reflectance (e.g.,). These calculations are based on the bidirectional reflectance distribution function (BRDF), which describes how the reflectance of a given surface depends on the view angle of the observer and the solar angle. BDRF can facilitate translations of observations of reflectance into albedo. Earth's average surface temperature due to its albedo and the greenhouse effect is currently about . If Earth were frozen entirely (and hence be more reflective), the average temperature of the planet would drop below . If only the continental land masses became covered by glaciers, the mean temperature of the planet would drop to about . In contrast, if the entire Earth was covered by water – a so-called ocean planet – the average temperature on the planet would rise to almost . In 2021, scientists reported that Earth dimmed by ~0.5% over two decades (1998–2017) as measured by earthshine using modern photometric techniques. This may have both been co-caused by climate change as well as a substantial increase in global warming. However, the link to climate change has not been explored to date and it is unclear whether or not this represents an ongoing trend. White-sky, black-sky, and blue-sky albedo For land surfaces, it has been shown that the albedo at a particular solar zenith angle θi can be approximated by the proportionate sum of two terms: the directional-hemispherical reflectance at that solar zenith angle, , sometimes referred to as black-sky albedo, and the bi-hemispherical reflectance, , sometimes referred to as white-sky albedo. with being the proportion of direct radiation from a given solar angle, and being the proportion of diffuse illumination, the actual albedo (also called blue-sky albedo) can then be given as: This formula is important because it allows the albedo to be calculated for any given illumination conditions from a knowledge of the intrinsic properties of the surface. Examples of terrestrial albedo effects Illumination Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of reflected light, except in circumstances where a change in illumination induces a change in the Earth's surface at that location (e.g. through melting of reflective ice). That said, albedo and illumination both vary by latitude. Albedo is highest near the poles and lowest in the subtropics, with a local maximum in the tropics. Insolation effects The intensity of albedo temperature effects depends on the amount of albedo and the level of local insolation (solar irradiance); high albedo areas in the Arctic and Antarctic regions are cold due to low insolation, whereas areas such as the Sahara Desert, which also have a relatively high albedo, will be hotter due to high insolation. Tropical and sub-tropical rainforest areas have low albedo, and are much hotter than their temperate forest counterparts, which have lower insolation. Because insolation plays such a big role in the heating and cooling effects of albedo, high insolation areas like the tropics will tend to show a more pronounced fluctuation in local temperature when local albedo changes. Arctic regions notably release more heat back into space than what they absorb, effectively cooling the Earth. This has been a concern since arctic ice and snow has been melting at higher rates due to higher temperatures, creating regions in the arctic that are notably darker (being water or ground which is darker color) and reflects less heat back into space. This feedback loop results in a reduced albedo effect. Climate and weather Albedo affects climate by determining how much radiation a planet absorbs. The uneven heating of Earth from albedo variations between land, ice, or ocean surfaces can drive weather. Albedo–temperature feedback When an area's albedo changes due to snowfall, a snow–temperature feedback results. A layer of snowfall increases local albedo, reflecting away sunlight, leading to local cooling. In principle, if no outside temperature change affects this area (e.g., a warm air mass), the raised albedo and lower temperature would maintain the current snow and invite further snowfall, deepening the snow–temperature feedback. However, because local weather is dynamic due to the change of seasons, eventually warm air masses and a more direct angle of sunlight (higher insolation) cause melting. When the melted area reveals surfaces with lower albedo, such as grass, soil, or ocean, the effect is reversed: the darkening surface lowers albedo, increasing local temperatures, which induces more melting and thus reducing the albedo further, resulting in still more heating. Snow Snow albedo is highly variable, ranging from as high as 0.9 for freshly fallen snow, to about 0.4 for melting snow, and as low as 0.2 for dirty snow. Over Antarctica snow albedo averages a little more than 0.8. If a marginally snow-covered area warms, snow tends to melt, lowering the albedo, and hence leading to more snowmelt because more radiation is being absorbed by the snowpack (the ice–albedo positive feedback). Just as fresh snow has a higher albedo than does dirty snow, the albedo of snow-covered sea ice is far higher than that of sea water. Sea water absorbs more solar radiation than would the same surface covered with reflective snow. When sea ice melts, either due to a rise in sea temperature or in response to increased solar radiation from above, the snow-covered surface is reduced, and more surface of sea water is exposed, so the rate of energy absorption increases. The extra absorbed energy heats the sea water, which in turn increases the rate at which sea ice melts. As with the preceding example of snowmelt, the process of melting of sea ice is thus another example of a positive feedback. Both positive feedback loops have long been recognized as important for global warming. Cryoconite, powdery windblown dust containing soot, sometimes reduces albedo on glaciers and ice sheets. The dynamical nature of albedo in response to positive feedback, together with the effects of small errors in the measurement of albedo, can lead to large errors in energy estimates. Because of this, in order to reduce the error of energy estimates, it is important to measure the albedo of snow-covered areas through remote sensing techniques rather than applying a single value for albedo over broad regions. Small-scale effects Albedo works on a smaller scale, too. In sunlight, dark clothes absorb more heat and light-coloured clothes reflect it better, thus allowing some control over body temperature by exploiting the albedo effect of the colour of external clothing. Solar photovoltaic effects Albedo can affect the electrical energy output of solar photovoltaic devices. For example, the effects of a spectrally responsive albedo are illustrated by the differences between the spectrally weighted albedo of solar photovoltaic technology based on hydrogenated amorphous silicon (a-Si:H) and crystalline silicon (c-Si)-based compared to traditional spectral-integrated albedo predictions. Research showed impacts of over 10% for vertically (90°) mounted systems, but such effects were substantially lower for systems with lower surface tilts. Spectral albedo strongly affects the performance of bifacial solar cells where rear surface performance gains of over 20% have been observed for c-Si cells installed above healthy vegetation. An analysis on the bias due to the specular reflectivity of 22 commonly occurring surface materials (both human-made and natural) provided effective albedo values for simulating the performance of seven photovoltaic materials mounted on three common photovoltaic system topologies: industrial (solar farms), commercial flat rooftops and residential pitched-roof applications. Trees Because forests generally have a low albedo, (the majority of the ultraviolet and visible spectrum is absorbed through photosynthesis), some scientists have suggested that greater heat absorption by trees could offset some of the carbon benefits of afforestation (or offset the negative climate impacts of deforestation). In the case of evergreen forests with seasonal snow cover albedo reduction may be great enough for deforestation to cause a net cooling effect. Trees also impact climate in extremely complicated ways through evapotranspiration. The water vapor causes cooling on the land surface, causes heating where it condenses, acts a strong greenhouse gas, and can increase albedo when it condenses into clouds. Scientists generally treat evapotranspiration as a net cooling impact, and the net climate impact of albedo and evapotranspiration changes from deforestation depends greatly on local climate. In seasonally snow-covered zones, winter albedos of treeless areas are 10% to 50% higher than nearby forested areas because snow does not cover the trees as readily. Deciduous trees have an albedo value of about 0.15 to 0.18 whereas coniferous trees have a value of about 0.09 to 0.15. Variation in summer albedo across both forest types is associated with maximum rates of photosynthesis because plants with high growth capacity display a greater fraction of their foliage for direct interception of incoming radiation in the upper canopy. The result is that wavelengths of light not used in photosynthesis are more likely to be reflected back to space rather than being absorbed by other surfaces lower in the canopy. Studies by the Hadley Centre have investigated the relative (generally warming) effect of albedo change and (cooling) effect of carbon sequestration on planting forests. They found that new forests in tropical and midlatitude areas tended to cool; new forests in high latitudes (e.g., Siberia) were neutral or perhaps warming. Water Water reflects light very differently from typical terrestrial materials. The reflectivity of a water surface is calculated using the Fresnel equations. At the scale of the wavelength of light even wavy water is always smooth so the light is reflected in a locally specular manner (not diffusely). The glint of light off water is a commonplace effect of this. At small angles of incident light, waviness results in reduced reflectivity because of the steepness of the reflectivity-vs.-incident-angle curve and a locally increased average incident angle. Although the reflectivity of water is very low at low and medium angles of incident light, it becomes very high at high angles of incident light such as those that occur on the illuminated side of Earth near the terminator (early morning, late afternoon, and near the poles). However, as mentioned above, waviness causes an appreciable reduction. Because light specularly reflected from water does not usually reach the viewer, water is usually considered to have a very low albedo in spite of its high reflectivity at high angles of incident light. Note that white caps on waves look white (and have high albedo) because the water is foamed up, so there are many superimposed bubble surfaces which reflect, adding up their reflectivities. Fresh 'black' ice exhibits Fresnel reflection. Snow on top of this sea ice increases the albedo to 0.9. Clouds Cloud albedo has substantial influence over atmospheric temperatures. Different types of clouds exhibit different reflectivity, theoretically ranging in albedo from a minimum of near 0 to a maximum approaching 0.8. "On any given day, about half of Earth is covered by clouds, which reflect more sunlight than land and water. Clouds keep Earth cool by reflecting sunlight, but they can also serve as blankets to trap warmth." Albedo and climate in some areas are affected by artificial clouds, such as those created by the contrails of heavy commercial airliner traffic. A study following the burning of the Kuwaiti oil fields during Iraqi occupation showed that temperatures under the burning oil fires were as much as colder than temperatures several miles away under clear skies. Aerosol effects Aerosols (very fine particles/droplets in the atmosphere) have both direct and indirect effects on Earth's radiative balance. The direct (albedo) effect is generally to cool the planet; the indirect effect (the particles act as cloud condensation nuclei and thereby change cloud properties) is less certain. As per Spracklen et al. the effects are: Aerosol direct effect. Aerosols directly scatter and absorb radiation. The scattering of radiation causes atmospheric cooling, whereas absorption can cause atmospheric warming. Aerosol indirect effect. Aerosols modify the properties of clouds through a subset of the aerosol population called cloud condensation nuclei. Increased nuclei concentrations lead to increased cloud droplet number concentrations, which in turn leads to increased cloud albedo, increased light scattering and radiative cooling (first indirect effect), but also leads to reduced precipitation efficiency and increased lifetime of the cloud (second indirect effect). In extremely polluted cities like Delhi, aerosol pollutants influence local weather and induce an urban cool island effect during the day. Black carbon Another albedo-related effect on the climate is from black carbon particles. The size of this effect is difficult to quantify: the Intergovernmental Panel on Climate Change estimates that the global mean radiative forcing for black carbon aerosols from fossil fuels is +0.2 W m−2, with a range +0.1 to +0.4 W m−2. Black carbon is a bigger cause of the melting of the polar ice cap in the Arctic than carbon dioxide due to its effect on the albedo. Human activities Human activities (e.g., deforestation, farming, and urbanization) change the albedo of various areas around the globe. As per Campra et al., human impacts to "the physical properties of the land surface can perturb the climate by altering the Earth’s radiative energy balance" even on a small scale or when undetected by satellites. The tens of thousands of hectares of greenhouses in Almería, Spain form a large expanse of whitened plastic roofs. A 2008 study found that this anthropogenic change lowered the local surface area temperature of the high-albedo area, although changes were localized. A follow-up study found that "CO2-eq. emissions associated to changes in surface albedo are a consequence of land transformation" and can reduce surface temperature increases associated with climate change. It has been found that urbanization generally decreases albedo (commonly being 0.01–0.02 lower than adjacent croplands), which contributes to global warming. Deliberately increasing albedo in urban areas can mitigate urban heat island. Ouyang et al. estimated that, on a global scale, "an albedo increase of 0.1 in worldwide urban areas would result in a cooling effect that is equivalent to absorbing ~44 Gt of CO2 emissions." Intentionally enhancing the albedo of the Earth's surface, along with its daytime thermal emittance, has been proposed as a solar radiation management strategy to mitigate energy crises and global warming known as passive daytime radiative cooling (PDRC). Efforts toward widespread implementation of PDRCs may focus on maximizing the albedo of surfaces from very low to high values, so long as a thermal emittance of at least 90% can be achieved. Astronomical albedo In astronomy, the term albedo can be defined in several different ways, depending upon the application and the wavelength of electromagnetic radiation involved. Optical or visual albedo The albedos of planets, satellites and minor planets such as asteroids can be used to infer much about their properties. The study of albedos, their dependence on wavelength, lighting angle ("phase angle"), and variation in time composes a major part of the astronomical field of photometry. For small and far objects that cannot be resolved by telescopes, much of what we know comes from the study of their albedos. For example, the absolute albedo can indicate the surface ice content of outer Solar System objects, the variation of albedo with phase angle gives information about regolith properties, whereas unusually high radar albedo is indicative of high metal content in asteroids. Enceladus, a moon of Saturn, has one of the highest known optical albedos of any body in the Solar System, with an albedo of 0.99. Another notable high-albedo body is Eris, with an albedo of 0.96. Many small objects in the outer Solar System and asteroid belt have low albedos down to about 0.05. A typical comet nucleus has an albedo of 0.04. Such a dark surface is thought to be indicative of a primitive and heavily space weathered surface containing some organic compounds. The overall albedo of the Moon is measured to be around 0.14, but it is strongly directional and non-Lambertian, displaying also a strong opposition effect. Although such reflectance properties are different from those of any terrestrial terrains, they are typical of the regolith surfaces of airless Solar System bodies. Two common optical albedos that are used in astronomy are the (V-band) geometric albedo (measuring brightness when illumination comes from directly behind the observer) and the Bond albedo (measuring total proportion of electromagnetic energy reflected). Their values can differ significantly, which is a common source of confusion. In detailed studies, the directional reflectance properties of astronomical bodies are often expressed in terms of the five Hapke parameters which semi-empirically describe the variation of albedo with phase angle, including a characterization of the opposition effect of regolith surfaces. One of these five parameters is yet another type of albedo called the single-scattering albedo. It is used to define scattering of electromagnetic waves on small particles. It depends on properties of the material (refractive index), the size of the particle, and the wavelength of the incoming radiation. An important relationship between an object's astronomical (geometric) albedo, absolute magnitude and diameter is given by: where is the astronomical albedo, is the diameter in kilometers, and is the absolute magnitude. Radar albedo In planetary radar astronomy, a microwave (or radar) pulse is transmitted toward a planetary target (e.g. Moon, asteroid, etc.) and the echo from the target is measured. In most instances, the transmitted pulse is circularly polarized and the received pulse is measured in the same sense of polarization as the transmitted pulse (SC) and the opposite sense (OC). The echo power is measured in terms of radar cross-section, , , or (total power, SC + OC) and is equal to the cross-sectional area of a metallic sphere (perfect reflector) at the same distance as the target that would return the same echo power. Those components of the received echo that return from first-surface reflections (as from a smooth or mirror-like surface) are dominated by the OC component as there is a reversal in polarization upon reflection. If the surface is rough at the wavelength scale or there is significant penetration into the regolith, there will be a significant SC component in the echo caused by multiple scattering. For most objects in the solar system, the OC echo dominates and the most commonly reported radar albedo parameter is the (normalized) OC radar albedo (often shortened to radar albedo): where the denominator is the effective cross-sectional area of the target object with mean radius, . A smooth metallic sphere would have . Radar albedos of Solar System objects The values reported for the Moon, Mercury, Mars, Venus, and Comet P/2005 JQ5 are derived from the total (OC+SC) radar albedo reported in those references. Relationship to surface bulk density In the event that most of the echo is from first surface reflections ( or so), the OC radar albedo is a first-order approximation of the Fresnel reflection coefficient (aka reflectivity) and can be used to estimate the bulk density of a planetary surface to a depth of a meter or so (a few wavelengths of the radar wavelength which is typically at the decimeter scale) using the following empirical relationships: .

Alphabet

An alphabet is a standardized set of basic written graphemes (called letters) representing phonemes, units of sounds that distinguish words, of certain spoken languages. Not all writing systems represent language in this way; in a syllabary, each character represents a syllable, and logographic systems use characters to represent words, morphemes, or other semantic units. The Egyptians are believed to have created the first alphabet in a technical sense. The short uniliteral signs are used to write pronunciation guides for logograms, or a character that represents a word, or morpheme, and later on, being used to write foreign words. This was used up to the 5th century AD. The first fully phonemic script, the Proto-Sinaitic script, which developed into the Phoenician alphabet, is considered to be the first alphabet and is the ancestor of most modern alphabets, abjads, and abugidas, including Arabic, Cyrillic, Greek, Hebrew, Latin, and possibly Brahmic. It was created by Semitic-speaking workers and slaves in the Sinai Peninsula in modern-day Egypt, by selecting a small number of hieroglyphs commonly seen in their Egyptian surroundings to describe the sounds, as opposed to the semantic values of the Canaanite languages. Peter T. Daniels distinguishes an abugida, a set of graphemes that represent consonantal base letters that diacritics modify to represent vowels, like in Devanagari and other South Asian scripts, an abjad, in which letters predominantly or exclusively represent consonants such as the original Phoenician, Hebrew or Arabic, and an alphabet, a set of graphemes that represent both consonants and vowels. In this narrow sense of the word, the first true alphabet was the Greek alphabet, which was based on the earlier Phoenician abjad. Alphabets are usually associated with a standard ordering of letters. This makes them useful for purposes of collation, which allows words to be sorted in a specific order, commonly known as the alphabetical order. It also means that their letters can be used as an alternative method of "numbering" ordered items, in such contexts as numbered lists and number placements. There are also names for letters in some languages. This is known as acrophony; It is present in some modern scripts, such as Greek, and many Semitic scripts, such as Arabic, Hebrew, and Syriac. It was used in some ancient alphabets, such as in Phoenician. However, this system is not present in all languages, such as the Latin alphabet, which adds a vowel after a character for each letter. Some systems also used to have this system but later on abandoned it for a system similar to Latin, such as Cyrillic. Etymology The English word alphabet came into Middle English from the Late Latin word alphabetum, which in turn originated in the Greek, ἀλφάβητος (alphabētos); it was made from the first two letters of the Greek alphabet, alpha (α) and beta (β). The names for the Greek letters, in turn, came from the first two letters of the Phoenician alphabet: aleph, the word for ox, and bet, the word for house. History Ancient Northeast African and Middle Eastern scripts The history of the alphabet started in the Middle East. Egyptian writing had a set of some 24 hieroglyphs that are called uniliterals, which are glyphs that provide one sound. These glyphs were used as pronunciation guides for logograms, to write grammatical inflections, and, later, to transcribe loan words and foreign names. The script was used a fair amount in the 4th century CE. However, after pagan temples were closed down, it was forgotten in the 5th century until the discovery of the Rosetta Stone. There was also the Cuneiform script. The script was used to write several ancient languages. However, it was primarily used to write Sumerian. The last known use of the Cuneiform script was in 75 CE, after which the script fell out of use. In the Middle Bronze Age, an apparently "alphabetic" system known as the Proto-Sinaitic script appeared in Egyptian turquoise mines in the Sinai peninsula dated circa 15th century BCE, apparently left by Canaanite workers. In 1999, John and Deborah Darnell, American Egyptologists, discovered an earlier version of this first alphabet at the Wadi el-Hol valley in Egypt. The script dated to circa 1800 BCE and shows evidence of having been adapted from specific forms of Egyptian hieroglyphs that could be dated to circa 2000 BCE, strongly suggesting that the first alphabet had developed about that time. The script was based on letter appearances and names, believed to be based on Egyptian hieroglyphs. This script had no characters representing vowels. Originally, it probably was a syllabary—a script where syllables are represented with characters—with symbols that were not needed being removed. It was an alphabetic cuneiform script with 30 signs, including three that indicate the following vowel invented in Ugarit before the 15th century BCE. This script was not used after the destruction of Ugarit in 1178 BCE.The Proto-Sinaitic script eventually developed into the Phoenician alphabet, conventionally called "Proto-Canaanite" before circa 1050 BCE. The oldest text in Phoenician script is an inscription on the sarcophagus of King Ahiram circa 1000 BCE. This script is the parent script of all western alphabets. By the tenth century BCE, two other forms distinguish themselves, Canaanite and Aramaic. The Aramaic gave rise to the Hebrew script. The South Arabian alphabet, a sister script to the Phoenician alphabet, is the script from which the Ge'ez alphabet, an abugida, a writing system where consonant-vowel sequences are written as units, which was used around the horn of Africa, descended. Vowel-less alphabets are called abjads, currently exemplified in others such as Arabic, Hebrew, and Syriac. The omission of vowels was not always a satisfactory solution due to the need of preserving sacred texts. "Weak" consonants are used to indicate vowels. These letters have a dual function since they can also be used as pure consonants. The Proto-Sinaitic script and the Ugaritic script were the first scripts with a limited number of signs instead of using many different signs for words, in contrast to the other widely used writing systems at the time, Cuneiform, Egyptian hieroglyphs, and Linear B. The Phoenician script was probably the first phonemic script, and it contained only about two dozen distinct letters, making it a script simple enough for traders to learn. Another advantage of the Phoenician alphabet was that it could write different languages since it recorded words phonemically. The Phoenician script was spread across the Mediterranean by the Phoenicians. The Late Mycenaeans added vowels to the alphabet. This new script, Linear B, gave rise to the ancestor of all alphabets in the West. The Greek Alphabet was the first alphabet in which vowels have independent letter forms separate from those of consonants. The Greeks chose letters representing sounds that did not exist in Phoenician to represent vowels. The syllabical Linear B, a script that was used by the Mycenaean Greeks from the 16th century BCE, had 87 symbols, including five vowels. In its early years, there were many variants of the Greek alphabet, causing many different alphabets to evolve from it. European alphabets The Greek alphabet, in Euboean form, was carried over by Greek colonists to the Italian peninsula circa 800-600 BCE giving rise to many different alphabets used to write the Italic languages. Like the Etruscan alphabet. One of these became the Latin alphabet, which spread across Europe as the Romans expanded their republic. After the fall of the Western Roman state and later the Eastern Roman state, the alphabet survived in intellectual and religious works. It came to be used for the descendant languages of Latin (the Romance languages) and most of the other languages of western and central Europe. Being the most widely used script in the world. The Etruscan alphabet remained nearly unchanged for several hundred years. Only evolving once the Etruscan language changed itself. The letters used for non-existent phonemes were dropped. Afterwards, however, the alphabet went through many different changes. The final classical form of Etruscan contained 20 letters. Four of them are vowels (a, e, i, and u). Six fewer letters than the earlier forms. The script in its classical form was used until the 1st century CE. The Etruscan language itself was not used in imperial Rome, but the script was used for religious texts. Some adaptations of the Latin alphabet have ligatures, a combination of two letters make one, such as æ in Danish and Icelandic and Ȣ in Algonquian; borrowings from other alphabets, such as the thorn þ in Old English and Icelandic, which came from the Futhark runes; and modified existing letters, such as the eth ð of Old English and Icelandic, which is a modified d. Other alphabets only use a subset of the Latin alphabet, such as Hawaiian and Italian, which uses the letters j, k, x, y, and w only in foreign words. Another notable script is Elder Futhark, believed to have evolved out of one of the Old Italic alphabets. Elder Futhark gave rise to other alphabets known collectively as the Runic alphabets. The Runic alphabets were used for Germanic languages from 100 CE to the late Middle Ages, being engraved on stone and jewelry, although inscriptions found on bone and wood occasionally appear. These alphabets have since been replaced with the Latin alphabet. The exception was for decorative use, where the runes remained in use until the 20th century. The Old Hungarian script was the writing system of the Hungarians. It was in use during the entire history of Hungary, albeit not as an official writing system. From the 19th century, it once again became more and more popular. The Glagolitic alphabet was the initial script of the liturgical language Old Church Slavonic and became, together with the Greek uncial script, the basis of the Cyrillic script. Cyrillic is one of the most widely used modern alphabetic scripts and is notable for its use in Slavic languages and also for other languages within the former Soviet Union. Cyrillic alphabets include Serbian, Macedonian, Bulgarian, Russian, Belarusian, and Ukrainian. The Glagolitic alphabet is believed to have been created by Saints Cyril and Methodius, while the Cyrillic alphabet was created by Clement of Ohrid, their disciple. They feature many letters that appear to have been borrowed from or influenced by Greek and Hebrew. Asian alphabets Beyond the logographic Chinese writing, many phonetic scripts exist in Asia. The Arabic alphabet, Hebrew alphabet, Syriac alphabet, and other abjads of the Middle East are developments of the Aramaic alphabet. Most alphabetic scripts of India and Eastern Asia descend from the Brahmi script, believed to be a descendant of Aramaic. Hangul In Korea, Sejong the Great created the Hangul alphabet in 1443 CE. Hangul is a unique alphabet: it is a featural alphabet, where the design of many of the letters comes from a sound's place of articulation, like P looking like the widened mouth and L looking like the tongue pulled in. The creation of Hangul was planned by the government of the day, and it places individual letters in syllable clusters with equal dimensions, in the same way as Chinese characters. This change allows for mixed-script writing, where one syllable always takes up one type space no matter how many letters get stacked into building that one sound-block. Zhuyin Zhuyin, sometimes referred to as Bopomofo, is a semi-syllabary. It transcribes Mandarin phonetically in the Republic of China. After the later establishment of the People's Republic of China and its adoption of Hanyu Pinyin, the use of Zhuyin today is limited. However, it is still widely used in Taiwan, where the Republic of China governs. Zhuyin developed from a form of Chinese shorthand based on Chinese characters in the early 1900s and has elements of both an alphabet and a syllabary. Like an alphabet, the phonemes of syllable initials are represented by individual symbols, but like a syllabary, the phonemes of the syllable finals are not; each possible final (excluding the medial glide) has its own character, an example being luan written as ㄌㄨㄢ (l-u-an). The last symbol ㄢ takes place as the entire final -an. While Zhuyin is not a mainstream writing system, it is still often used in ways similar to a romanization system, for aiding pronunciation and as an input method for Chinese characters on computers and cellphones. Romanization European alphabets, especially Latin and Cyrillic, have been adapted for many languages of Asia. Arabic is also widely used, sometimes as an abjad, as with Urdu and Persian, and sometimes as a complete alphabet, as with Kurdish and Uyghur. Types The term "alphabet" is used by linguists and paleographers in both a wide and a narrow sense. In a broader sense, an alphabet is a segmental script at the phoneme level—that is, it has separate glyphs for individual sounds and not for larger units such as syllables or words. In the narrower sense, some scholars distinguish "true" alphabets from two other types of segmental script, abjads, and abugidas. These three differ in how they treat vowels. Abjads have letters for consonants and leave most vowels unexpressed. Abugidas are also consonant-based but indicate vowels with diacritics, a systematic graphic modification of the consonants. The earliest known alphabet using this sense is the Wadi el-Hol script, believed to be an abjad. Its successor, Phoenician, is the ancestor of modern alphabets, including Arabic, Greek, Latin (via the Old Italic alphabet), Cyrillic (via the Greek alphabet), and Hebrew (via Aramaic). Examples of present-day abjads are the Arabic and Hebrew scripts; true alphabets include Latin, Cyrillic, and Korean Hangul; and abugidas, used to write Tigrinya, Amharic, Hindi, and Thai. The Canadian Aboriginal syllabics are also an abugida, rather than a syllabary, as their name would imply, because each glyph stands for a consonant and is modified by rotation to represent the following vowel. In a true syllabary, each consonant-vowel combination gets represented by a separate glyph. All three types may be augmented with syllabic glyphs. Ugaritic, for example, is essentially an abjad but has syllabic letters for These are the only times that vowels are indicated. Coptic has a letter for . Devanagari is typically an abugida augmented with dedicated letters for initial vowels, though some traditions use अ as a zero consonant as the graphic base for such vowels. The boundaries between the three types of segmental scripts are not always clear-cut. For example, Sorani Kurdish is written in the Arabic script, which, when used for other languages, is an abjad. In Kurdish, writing the vowels is mandatory, and whole letters are used, so the script is a true alphabet. Other languages may use a Semitic abjad with forced vowel diacritics, effectively making them abugidas. On the other hand, the Phagspa script of the Mongol Empire was based closely on the Tibetan abugida, but vowel marks are written after the preceding consonant rather than as diacritic marks. Although short a is not written, as in the Indic abugidas, The source of the term "abugida," namely the Ge'ez abugida now used for Amharic and Tigrinya, has assimilated into their consonant modifications. It is no longer systematic and must be learned as a syllabary rather than as a segmental script. Even more extreme, the Pahlavi abjad eventually became logographic. Thus the primary categorisation of alphabets reflects how they treat vowels. For tonal languages, further classification can be based on their treatment of tone. Though names do not yet exist to distinguish the various types. Some alphabets disregard tone entirely, especially when it does not carry a heavy functional load, as in Somali and many other languages of Africa and the Americas. Most commonly, tones are indicated by diacritics, which is how vowels are treated in abugidas, which is the case for Vietnamese (a true alphabet) and Thai (an abugida). In Thai, the tone is determined primarily by a consonant, with diacritics for disambiguation. In the Pollard script, an abugida, vowels are indicated by diacritics. The placing of the diacritic relative to the consonant is modified to indicate the tone. More rarely, a script may have separate letters for tones, as is the case for Hmong and Zhuang. For many, regardless of whether letters or diacritics get used, the most common tone is not marked, just as the most common vowel is not marked in Indic abugidas. In Zhuyin, not only is one of the tones unmarked; but there is a diacritic to indicate a lack of tone, like the virama of Indic. Alphabetical order Alphabets often come to be associated with a standard ordering of their letters; this is for collation—namely, for listing words and other items in alphabetical order. Latin Alphabets The basic ordering of the Latin alphabet (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z), which derives from the Northwest Semitic "Abgad" order, is already well established. Although, languages using this alphabet have different conventions for their treatment of modified letters (such as the French é, à, and ô) and certain combinations of letters (multigraphs). In French, these are not considered to be additional letters for collation. However, in Icelandic, the accented letters such as á, í, and ö are considered distinct letters representing different vowel sounds from sounds represented by their unaccented counterparts. In Spanish, ñ is considered a separate letter, but accented vowels such as á and é are not. The ll and ch were also formerly considered single letters and sorted separately after l and c, but in 1994, the tenth congress of the Association of Spanish Language Academies changed the collating order so that ll came to be sorted between lk and lm in the dictionary and ch came to be sorted between cg and ci; those digraphs were still formally designated as letters, but in 2010 the Real Academia Española changed it, so they are no longer considered letters at all. In German, words starting with sch- (which spells the German phoneme ) are inserted between words with initial sca- and sci- (all incidentally loanwords) instead of appearing after the initial sz, as though it were a single letter, which contrasts several languages such as Albanian, in which dh-, ë-, gj-, ll-, rr-, th-, xh-, and zh-, which all represent phonemes and considered separate single letters, would follow the letters d, e, g, l, n, r, t, x, and z, respectively, as well as Hungarian and Welsh. Further, German words with an umlaut get collated ignoring the umlaut as—contrary to Turkish, which adopted the graphemes ö and ü, and where a word like tüfek would come after tuz, in the dictionary. An exception is the German telephone directory, where umlauts are sorted like ä=ae since names such as Jäger also appear with the spelling Jaeger and are not distinguished in the spoken language. The Danish and Norwegian alphabets end with æ—ø—å, whereas the Swedish conventionally put å—ä—ö at the end. However, æ phonetically corresponds with ä, as does ø and ö. Early Alphabets It is unknown whether the earliest alphabets had a defined sequence. Some alphabets today, such as the Hanuno'o script, are learned one letter at a time, in no particular order, and are not used for collation where a definite order is required. However, a dozen Ugaritic tablets from the fourteenth century BCE preserve the alphabet in two sequences. One, the ABCDE order later used in Phoenician, has continued with minor changes in Hebrew, Greek, Armenian, Gothic, Cyrillic, and Latin; the other, HMĦLQ, was used in southern Arabia and is preserved today in Ethiopic. Both orders have therefore been stable for at least 3000 years. Runic used an unrelated Futhark sequence, which got simplified later on. Arabic uses usually uses its sequence, although Arabic retains the traditional abjadi order, which is used for numbers. The Brahmic family of alphabets used in India uses a unique order based on phonology: The letters are arranged according to how and where the sounds get produced in the mouth. This organization is present in Southeast Asia, Tibet, Korean hangul, and even Japanese kana, which is not an alphabet. Acrophony In Phoenician, each letter got associated with a word that begins with that sound. This is called acrophony and is continuously used to varying degrees in Samaritan, Aramaic, Syriac, Hebrew, Greek, and Arabic. Acrophony got abandoned in Latin. It referred to the letters by adding a vowel (usually "e," sometimes "a," or "u") before or after the consonant. Two exceptions were Y and Z, which were borrowed from the Greek alphabet rather than Etruscan. They were known as Y Graeca "Greek Y" and zeta (from Greek)—this discrepancy was inherited by many European languages, as in the term zed for Z in all forms of English, other than American English. Over time names sometimes shifted or were added, as in double U for W, or "double V" in French, the English name for Y, and the American zee for Z. Comparing them in English and French gives a clear reflection of the Great Vowel Shift: A, B, C, and D are pronounced in today's English, but in contemporary French they are . The French names (from which the English names got derived) preserve the qualities of the English vowels before the Great Vowel Shift. By contrast, the names of F, L, M, N, and S () remain the same in both languages because "short" vowels were largely unaffected by the Shift. In Cyrillic, originally, acrophony was present using Slavic words. The first three words going, azŭ, buky, vědě, with the Cyrillic collation order being, А, Б, В. However, this was later abandoned in favor of a system similar to Latin. Orthography and pronunciation When an alphabet is adopted or developed to represent a given language, an orthography generally comes into being, providing rules for spelling words, following the principle on which alphabets get based. These rules will map letters of the alphabet to the phonemes of the spoken language. In a perfectly phonemic orthography, there would be a consistent one-to-one correspondence between the letters and the phonemes so that a writer could predict the spelling of a word given its pronunciation, and a speaker would always know the pronunciation of a word given its spelling, and vice versa. However, this ideal is usually never achieved in practice. Languages can come close to it, such as Spanish and Finnish. others, such as English, deviate from it to a much larger degree. The pronunciation of a language often evolves independently of its writing system. Writing systems have been borrowed for languages the orthography was not initially made to use. The degree to which letters of an alphabet correspond to phonemes of a language varies. Languages may fail to achieve a one-to-one correspondence between letters and sounds in any of several ways: A language may represent a given phoneme by combinations of letters rather than just a single letter. Two-letter combinations are called digraphs, and three-letter groups are called trigraphs. German uses the tetragraphs (four letters) "tsch" for the phoneme and (in a few borrowed words) "dsch" for . Kabardian also uses a tetragraph for one of its phonemes, namely "кхъу." Two letters representing one sound occur in several instances in Hungarian as well (where, for instance, cs stands for [tʃ], sz for [s], zs for [ʒ], dzs for [dʒ]). A language may represent the same phoneme with two or more different letters or combinations of letters. An example is modern Greek which may write the phoneme in six different ways: , , , , , and . A language may spell some words with unpronounced letters that exist for historical or other reasons. For example, the spelling of the Thai word for "beer" [เบียร์] retains a letter for the final consonant "r" present in the English word it borrows, but silences it. Pronunciation of individual words may change according to the presence of surrounding words in a sentence, for example, in Sandhi. Different dialects of a language may use different phonemes for the same word. A language may use different sets of symbols or rules for distinct vocabulary items, typically for foreign words, such as in the Japanese katakana syllabary is used for foreign words, and there are rules in English for using loanwords from other languages. National languages sometimes elect to address the problem of dialects by associating the alphabet with the national standard. Some national languages like Finnish, Armenian, Turkish, Russian, Serbo-Croatian (Serbian, Croatian, and Bosnian), and Bulgarian have a very regular spelling system with nearly one-to-one correspondence between letters and phonemes. Similarly, the Italian verb corresponding to 'spell (out),' compitare, is unknown to many Italians because spelling is usually trivial, as Italian spelling is highly phonemic. In standard Spanish, one can tell the pronunciation of a word from its spelling, but not vice versa, as phonemes sometimes can be represented in more than one way, but a given letter is consistently pronounced. French using silent letters, nasal vowels, and elision, may seem to lack much correspondence between the spelling and pronunciation. However, its rules on pronunciation, though complex, are consistent and predictable with a fair degree of accuracy. At the other extreme are languages such as English, where pronunciations mostly have to be memorized as they do not correspond to the spelling consistently. For English, this is because the Great Vowel Shift occurred after the orthography got established and because English has acquired a large number of loanwords at different times, retaining their original spelling at varying levels. However, even English has general, albeit complex, rules that predict pronunciation from spelling. Rules like this are usually successful. However, rules to predict spelling from pronunciation have a higher failure rate. Sometimes, countries have the written language undergo a spelling reform to realign the writing with the contemporary spoken language. These can range from simple spelling changes and word forms to switching the entire writing system. For example, Turkey switched from the Arabic alphabet to a Latin-based Turkish alphabet, and when Kazakh changed from an Arabic script to a Cyrillic script due to the Soviet Union's influence, and in 2021, it made a transition to the Latin alphabet, similar to Turkish. The Cyrillic script used to be official in Uzbekistan and Turkmenistan before they all switched to the Latin alphabet, including Uzbekistan that is having a reform of the alphabet to use diacritics on the letters that are marked by apostrophes and the letters that are digraphs. The standard system of symbols used by linguists to represent sounds in any language, independently of orthography, is called the International Phonetic Alphabet.

Atomic number

The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements. In an ordinary uncharged atom, the atomic number is also equal to the number of electrons. For an ordinary atom, the sum of the atomic number Z and the neutron number N gives the atom's atomic mass number A. Since protons and neutrons have approximately the same mass (and the mass of the electrons is negligible for many purposes) and the mass defect of the nucleon binding is always small compared to the nucleon mass, the atomic mass of any atom, when expressed in unified atomic mass units (making a quantity called the "relative isotopic mass"), is within 1% of the whole number A. Atoms with the same atomic number but different neutron numbers, and hence different mass numbers, are known as isotopes. A little more than three-quarters of naturally occurring elements exist as a mixture of isotopes (see monoisotopic elements), and the average isotopic mass of an isotopic mixture for an element (called the relative atomic mass) in a defined environment on Earth, determines the element's standard atomic weight. Historically, it was these atomic weights of elements (in comparison to hydrogen) that were the quantities measurable by chemists in the 19th century. The conventional symbol Z comes from the German word 'number', which, before the modern synthesis of ideas from chemistry and physics, merely denoted an element's numerical place in the periodic table, whose order was then approximately, but not completely, consistent with the order of the elements by atomic weights. Only after 1915, with the suggestion and evidence that this Z number was also the nuclear charge and a physical characteristic of atoms, did the word (and its English equivalent atomic number) come into common use in this context. History The periodic table and a natural number for each element Loosely speaking, the existence or construction of a periodic table of elements creates an ordering of the elements, and so they can be numbered in order. Dmitri Mendeleev claimed that he arranged his first periodic tables (first published on March 6, 1869) in order of atomic weight ("Atomgewicht"). However, in consideration of the elements' observed chemical properties, he changed the order slightly and placed tellurium (atomic weight 127.6) ahead of iodine (atomic weight 126.9). This placement is consistent with the modern practice of ordering the elements by proton number, Z, but that number was not known or suspected at the time. A simple numbering based on periodic table position was never entirely satisfactory, however. Besides the case of iodine and tellurium, later several other pairs of elements (such as argon and potassium, cobalt and nickel) were known to have nearly identical or reversed atomic weights, thus requiring their placement in the periodic table to be determined by their chemical properties. However the gradual identification of more and more chemically similar lanthanide elements, whose atomic number was not obvious, led to inconsistency and uncertainty in the periodic numbering of elements at least from lutetium (element 71) onward (hafnium was not known at this time). The Rutherford-Bohr model and van den Broek In 1911, Ernest Rutherford gave a model of the atom in which a central nucleus held most of the atom's mass and a positive charge which, in units of the electron's charge, was to be approximately equal to half of the atom's atomic weight, expressed in numbers of hydrogen atoms. This central charge would thus be approximately half the atomic weight (though it was almost 25% different from the atomic number of gold , ), the single element from which Rutherford made his guess). Nevertheless, in spite of Rutherford's estimation that gold had a central charge of about 100 (but was element on the periodic table), a month after Rutherford's paper appeared, Antonius van den Broek first formally suggested that the central charge and number of electrons in an atom was exactly equal to its place in the periodic table (also known as element number, atomic number, and symbolized Z). This proved eventually to be the case. Moseley's 1913 experiment The experimental position improved dramatically after research by Henry Moseley in 1913. Moseley, after discussions with Bohr who was at the same lab (and who had used Van den Broek's hypothesis in his Bohr model of the atom), decided to test Van den Broek's and Bohr's hypothesis directly, by seeing if spectral lines emitted from excited atoms fitted the Bohr theory's postulation that the frequency of the spectral lines be proportional to the square of Z. To do this, Moseley measured the wavelengths of the innermost photon transitions (K and L lines) produced by the elements from aluminum (Z = 13) to gold (Z = 79) used as a series of movable anodic targets inside an x-ray tube. The square root of the frequency of these photons increased from one target to the next in an arithmetic progression. This led to the conclusion (Moseley's law) that the atomic number does closely correspond (with an offset of one unit for K-lines, in Moseley's work) to the calculated electric charge of the nucleus, i.e. the element number Z. Among other things, Moseley demonstrated that the lanthanide series (from lanthanum to lutetium inclusive) must have 15 members—no fewer and no more—which was far from obvious from known chemistry at that time. Missing elements After Moseley's death in 1915, the atomic numbers of all known elements from hydrogen to uranium (Z = 92) were examined by his method. There were seven elements (with Z < 92) which were not found and therefore identified as still undiscovered, corresponding to atomic numbers 43, 61, 72, 75, 85, 87 and 91. From 1918 to 1947, all seven of these missing elements were discovered. By this time, the first four transuranium elements had also been discovered, so that the periodic table was complete with no gaps as far as curium (Z = 96). The proton and the idea of nuclear electrons In 1915, the reason for nuclear charge being quantized in units of Z, which were now recognized to be the same as the element number, was not understood. An old idea called Prout's hypothesis had postulated that the elements were all made of residues (or "protyles") of the lightest element hydrogen, which in the Bohr-Rutherford model had a single electron and a nuclear charge of one. However, as early as 1907, Rutherford and Thomas Royds had shown that alpha particles, which had a charge of +2, were the nuclei of helium atoms, which had a mass four times that of hydrogen, not two times. If Prout's hypothesis were true, something had to be neutralizing some of the charge of the hydrogen nuclei present in the nuclei of heavier atoms. In 1917, Rutherford succeeded in generating hydrogen nuclei from a nuclear reaction between alpha particles and nitrogen gas, and believed he had proven Prout's law. He called the new heavy nuclear particles protons in 1920 (alternate names being proutons and protyles). It had been immediately apparent from the work of Moseley that the nuclei of heavy atoms have more than twice as much mass as would be expected from their being made of hydrogen nuclei, and thus there was required a hypothesis for the neutralization of the extra protons presumed present in all heavy nuclei. A helium nucleus was presumed to be composed of four protons plus two "nuclear electrons" (electrons bound inside the nucleus) to cancel two of the charges. At the other end of the periodic table, a nucleus of gold with a mass 197 times that of hydrogen was thought to contain 118 nuclear electrons in the nucleus to give it a residual charge of +79, consistent with its atomic number. The discovery of the neutron makes Z the proton number All consideration of nuclear electrons ended with James Chadwick's discovery of the neutron in 1932. An atom of gold now was seen as containing 118 neutrons rather than 118 nuclear electrons, and its positive nuclear charge now was realized to come entirely from a content of 79 protons. Since Moseley had previously shown that the atomic number Z of an element equals this positive charge, it was now clear that Z is identical to the number of protons of its nuclei. Chemical properties Each element has a specific set of chemical properties as a consequence of the number of electrons present in the neutral atom, which is Z (the atomic number). The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element's electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. Hence, it is the atomic number alone that determines the chemical properties of an element; and it is for this reason that an element can be defined as consisting of any mixture of atoms with a given atomic number. New elements The quest for new elements is usually described using atomic numbers. As of , all elements with atomic numbers 1 to 118 have been observed. Synthesis of new elements is accomplished by bombarding target atoms of heavy elements with ions, such that the sum of the atomic numbers of the target and ion elements equals the atomic number of the element being created. In general, the half-life of a nuclide becomes shorter as atomic number increases, though undiscovered nuclides with certain "magic" numbers of protons and neutrons may have relatively longer half-lives and comprise an island of stability. A hypothetical element composed only of neutrons has also been proposed and would have atomic number 0.

Anatomy

Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic and microscopic. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology, and also in the study of cells. The history of anatomy is characterized by a progressive understanding of the functions of the organs and structures of the human body. Methods have also improved dramatically, advancing from the examination of animals by dissection of carcasses and cadavers (corpses) to 20th century medical imaging techniques, including X-ray, ultrasound, and magnetic resonance imaging. Etymology and definition Derived from the Greek anatomē "dissection" (from anatémnō "I cut up, cut open" from ἀνά aná "up," and τέμνω témnō "I cut"), anatomy is the scientific study of the structure of organisms including their systems, organs and tissues. It includes the appearance and position of the various parts, the materials from which they are composed, and their relationships with other parts. Anatomy is quite distinct from physiology and biochemistry, which deal respectively with the functions of those parts and the chemical processes involved. For example, an anatomist is concerned with the shape, size, position, structure, blood supply and innervation of an organ such as the liver; while a physiologist is interested in the production of bile, the role of the liver in nutrition and the regulation of bodily functions. The discipline of anatomy can be subdivided into a number of branches, including gross or macroscopic anatomy and microscopic anatomy. Gross anatomy is the study of structures large enough to be seen with the naked eye, and also includes superficial anatomy or surface anatomy, the study by sight of the external body features. Microscopic anatomy is the study of structures on a microscopic scale, along with histology (the study of tissues), and embryology (the study of an organism in its immature condition). Anatomy can be studied using both invasive and non-invasive methods with the goal of obtaining information about the structure and organization of organs and systems. Methods used include dissection, in which a body is opened and its organs studied, and endoscopy, in which a video camera-equipped instrument is inserted through a small incision in the body wall and used to explore the internal organs and other structures. Angiography using X-rays or magnetic resonance angiography are methods to visualize blood vessels. The term "anatomy" is commonly taken to refer to human anatomy. However, substantially similar structures and tissues are found throughout the rest of the animal kingdom, and the term also includes the anatomy of other animals. The term zootomy is also sometimes used to specifically refer to non-human animals. The structure and tissues of plants are of a dissimilar nature and they are studied in plant anatomy. Animal tissues The kingdom Animalia contains multicellular organisms that are heterotrophic and motile (although some have secondarily adopted a sessile lifestyle). Most animals have bodies differentiated into separate tissues and these animals are also known as eumetazoans. They have an internal digestive chamber, with one or two openings; the gametes are produced in multicellular sex organs, and the zygotes include a blastula stage in their embryonic development. Metazoans do not include the sponges, which have undifferentiated cells. Unlike plant cells, animal cells have neither a cell wall nor chloroplasts. Vacuoles, when present, are more in number and much smaller than those in the plant cell. The body tissues are composed of numerous types of cell, including those found in muscles, nerves and skin. Each typically has a cell membrane formed of phospholipids, cytoplasm and a nucleus. All of the different cells of an animal are derived from the embryonic germ layers. Those simpler invertebrates which are formed from two germ layers of ectoderm and endoderm are called diploblastic and the more developed animals whose structures and organs are formed from three germ layers are called triploblastic. All of a triploblastic animal's tissues and organs are derived from the three germ layers of the embryo, the ectoderm, mesoderm and endoderm. Animal tissues can be grouped into four basic types: connective, epithelial, muscle and nervous tissue. Connective tissue Connective tissues are fibrous and made up of cells scattered among inorganic material called the extracellular matrix. Connective tissue gives shape to organs and holds them in place. The main types are loose connective tissue, adipose tissue, fibrous connective tissue, cartilage and bone. The extracellular matrix contains proteins, the chief and most abundant of which is collagen. Collagen plays a major part in organizing and maintaining tissues. The matrix can be modified to form a skeleton to support or protect the body. An exoskeleton is a thickened, rigid cuticle which is stiffened by mineralization, as in crustaceans or by the cross-linking of its proteins as in insects. An endoskeleton is internal and present in all developed animals, as well as in many of those less developed. Epithelium Epithelial tissue is composed of closely packed cells, bound to each other by cell adhesion molecules, with little intercellular space. Epithelial cells can be squamous (flat), cuboidal or columnar and rest on a basal lamina, the upper layer of the basement membrane, the lower layer is the reticular lamina lying next to the connective tissue in the extracellular matrix secreted by the epithelial cells. There are many different types of epithelium, modified to suit a particular function. In the respiratory tract there is a type of ciliated epithelial lining; in the small intestine there are microvilli on the epithelial lining and in the large intestine there are intestinal villi. Skin consists of an outer layer of keratinized stratified squamous epithelium that covers the exterior of the vertebrate body. Keratinocytes make up to 95% of the cells in the skin. The epithelial cells on the external surface of the body typically secrete an extracellular matrix in the form of a cuticle. In simple animals this may just be a coat of glycoproteins. In more advanced animals, many glands are formed of epithelial cells. Muscle tissue Muscle cells (myocytes) form the active contractile tissue of the body. Muscle tissue functions to produce force and cause motion, either locomotion or movement within internal organs. Muscle is formed of contractile filaments and is separated into three main types; smooth muscle, skeletal muscle and cardiac muscle. Smooth muscle has no striations when examined microscopically. It contracts slowly but maintains contractibility over a wide range of stretch lengths. It is found in such organs as sea anemone tentacles and the body wall of sea cucumbers. Skeletal muscle contracts rapidly but has a limited range of extension. It is found in the movement of appendages and jaws. Obliquely striated muscle is intermediate between the other two. The filaments are staggered and this is the type of muscle found in earthworms that can extend slowly or make rapid contractions. In higher animals striated muscles occur in bundles attached to bone to provide movement and are often arranged in antagonistic sets. Smooth muscle is found in the walls of the uterus, bladder, intestines, stomach, oesophagus, respiratory airways, and blood vessels. Cardiac muscle is found only in the heart, allowing it to contract and pump blood round the body. Nervous tissue Nervous tissue is composed of many nerve cells known as neurons which transmit information. In some slow-moving radially symmetrical marine animals such as ctenophores and cnidarians (including sea anemones and jellyfish), the nerves form a nerve net, but in most animals they are organized longitudinally into bundles. In simple animals, receptor neurons in the body wall cause a local reaction to a stimulus. In more complex animals, specialized receptor cells such as chemoreceptors and photoreceptors are found in groups and send messages along neural networks to other parts of the organism. Neurons can be connected together in ganglia. In higher animals, specialized receptors are the basis of sense organs and there is a central nervous system (brain and spinal cord) and a peripheral nervous system. The latter consists of sensory nerves that transmit information from sense organs and motor nerves that influence target organs. The peripheral nervous system is divided into the somatic nervous system which conveys sensation and controls voluntary muscle, and the autonomic nervous system which involuntarily controls smooth muscle, certain glands and internal organs, including the stomach. Vertebrate anatomy All vertebrates have a similar basic body plan and at some point in their lives, mostly in the embryonic stage, share the major chordate characteristics: a stiffening rod, the notochord; a dorsal hollow tube of nervous material, the neural tube; pharyngeal arches; and a tail posterior to the anus. The spinal cord is protected by the vertebral column and is above the notochord, and the gastrointestinal tract is below it. Nervous tissue is derived from the ectoderm, connective tissues are derived from mesoderm, and gut is derived from the endoderm. At the posterior end is a tail which continues the spinal cord and vertebrae but not the gut. The mouth is found at the anterior end of the animal, and the anus at the base of the tail. The defining characteristic of a vertebrate is the vertebral column, formed in the development of the segmented series of vertebrae. In most vertebrates the notochord becomes the nucleus pulposus of the intervertebral discs. However, a few vertebrates, such as the sturgeon and the coelacanth, retain the notochord into adulthood. Jawed vertebrates are typified by paired appendages, fins or legs, which may be secondarily lost. The limbs of vertebrates are considered to be homologous because the same underlying skeletal structure was inherited from their last common ancestor. This is one of the arguments put forward by Charles Darwin to support his theory of evolution. Fish anatomy The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. The main skeletal element is the vertebral column, composed of articulating vertebrae which are lightweight yet strong. The ribs attach to the spine and there are no limbs or limb girdles. The main external features of the fish, the fins, are composed of either bony or soft spines called rays, which with the exception of the caudal fins, have no direct connection with the spine. They are supported by the muscles which compose the main part of the trunk. The heart has two chambers and pumps the blood through the respiratory surfaces of the gills and on round the body in a single circulatory loop. The eyes are adapted for seeing underwater and have only local vision. There is an inner ear but no external or middle ear. Low frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, and these respond to nearby movements and to changes in water pressure. Sharks and rays are basal fish with numerous primitive anatomical features similar to those of ancient fish, including skeletons composed of cartilage. Their bodies tend to be dorso-ventrally flattened, they usually have five pairs of gill slits and a large mouth set on the underside of the head. The dermis is covered with separate dermal placoid scales. They have a cloaca into which the urinary and genital passages open, but not a swim bladder. Cartilaginous fish produce a small number of large, yolky eggs. Some species are ovoviviparous and the young develop internally but others are oviparous and the larvae develop externally in egg cases. The bony fish lineage shows more derived anatomical traits, often with major evolutionary changes from the features of ancient fish. They have a bony skeleton, are generally laterally flattened, have five pairs of gills protected by an operculum, and a mouth at or near the tip of the snout. The dermis is covered with overlapping scales. Bony fish have a swim bladder which helps them maintain a constant depth in the water column, but not a cloaca. They mostly spawn a large number of small eggs with little yolk which they broadcast into the water column. Amphibian anatomy Amphibians are a class of animals comprising frogs, salamanders and caecilians. They are tetrapods, but the caecilians and a few species of salamander have either no limbs or their limbs are much reduced in size. Their main bones are hollow and lightweight and are fully ossified and the vertebrae interlock with each other and have articular processes. Their ribs are usually short and may be fused to the vertebrae. Their skulls are mostly broad and short, and are often incompletely ossified. Their skin contains little keratin and lacks scales, but contains many mucous glands and in some species, poison glands. The hearts of amphibians have three chambers, two atria and one ventricle. They have a urinary bladder and nitrogenous waste products are excreted primarily as urea. Amphibians breathe by means of buccal pumping, a pump action in which air is first drawn into the buccopharyngeal region through the nostrils. These are then closed and the air is forced into the lungs by contraction of the throat. They supplement this with gas exchange through the skin which needs to be kept moist. In frogs the pelvic girdle is robust and the hind legs are much longer and stronger than the forelimbs. The feet have four or five digits and the toes are often webbed for swimming or have suction pads for climbing. Frogs have large eyes and no tail. Salamanders resemble lizards in appearance; their short legs project sideways, the belly is close to or in contact with the ground and they have a long tail. Caecilians superficially resemble earthworms and are limbless. They burrow by means of zones of muscle contractions which move along the body and they swim by undulating their body from side to side. Reptile anatomy Reptiles are a class of animals comprising turtles, tuataras, lizards, snakes and crocodiles. They are tetrapods, but the snakes and a few species of lizard either have no limbs or their limbs are much reduced in size. Their bones are better ossified and their skeletons stronger than those of amphibians. The teeth are conical and mostly uniform in size. The surface cells of the epidermis are modified into horny scales which create a waterproof layer. Reptiles are unable to use their skin for respiration as do amphibians and have a more efficient respiratory system drawing air into their lungs by expanding their chest walls. The heart resembles that of the amphibian but there is a septum which more completely separates the oxygenated and deoxygenated bloodstreams. The reproductive system has evolved for internal fertilization, with a copulatory organ present in most species. The eggs are surrounded by amniotic membranes which prevents them from drying out and are laid on land, or develop internally in some species. The bladder is small as nitrogenous waste is excreted as uric acid. Turtles are notable for their protective shells. They have an inflexible trunk encased in a horny carapace above and a plastron below. These are formed from bony plates embedded in the dermis which are overlain by horny ones and are partially fused with the ribs and spine. The neck is long and flexible and the head and the legs can be drawn back inside the shell. Turtles are vegetarians and the typical reptile teeth have been replaced by sharp, horny plates. In aquatic species, the front legs are modified into flippers. Tuataras superficially resemble lizards but the lineages diverged in the Triassic period. There is one living species, Sphenodon punctatus. The skull has two openings (fenestrae) on either side and the jaw is rigidly attached to the skull. There is one row of teeth in the lower jaw and this fits between the two rows in the upper jaw when the animal chews. The teeth are merely projections of bony material from the jaw and eventually wear down. The brain and heart are more primitive than those of other reptiles, and the lungs have a single chamber and lack bronchi. The tuatara has a well-developed parietal eye on its forehead. Lizards have skulls with only one fenestra on each side, the lower bar of bone below the second fenestra having been lost. This results in the jaws being less rigidly attached which allows the mouth to open wider. Lizards are mostly quadrupeds, with the trunk held off the ground by short, sideways-facing legs, but a few species have no limbs and resemble snakes. Lizards have moveable eyelids, eardrums are present and some species have a central parietal eye. Snakes are closely related to lizards, having branched off from a common ancestral lineage during the Cretaceous period, and they share many of the same features. The skeleton consists of a skull, a hyoid bone, spine and ribs though a few species retain a vestige of the pelvis and rear limbs in the form of pelvic spurs. The bar under the second fenestra has also been lost and the jaws have extreme flexibility allowing the snake to swallow its prey whole. Snakes lack moveable eyelids, the eyes being covered by transparent "spectacle" scales. They do not have eardrums but can detect ground vibrations through the bones of their skull. Their forked tongues are used as organs of taste and smell and some species have sensory pits on their heads enabling them to locate warm-blooded prey. Crocodilians are large, low-slung aquatic reptiles with long snouts and large numbers of teeth. The head and trunk are dorso-ventrally flattened and the tail is laterally compressed. It undulates from side to side to force the animal through the water when swimming. The tough keratinized scales provide body armour and some are fused to the skull. The nostrils, eyes and ears are elevated above the top of the flat head enabling them to remain above the surface of the water when the animal is floating. Valves seal the nostrils and ears when it is submerged. Unlike other reptiles, crocodilians have hearts with four chambers allowing complete separation of oxygenated and deoxygenated blood. Bird anatomy Birds are tetrapods but though their hind limbs are used for walking or hopping, their front limbs are wings covered with feathers and adapted for flight. Birds are endothermic, have a high metabolic rate, a light skeletal system and powerful muscles. The long bones are thin, hollow and very light. Air sac extensions from the lungs occupy the centre of some bones. The sternum is wide and usually has a keel and the caudal vertebrae are fused. There are no teeth and the narrow jaws are adapted into a horn-covered beak. The eyes are relatively large, particularly in nocturnal species such as owls. They face forwards in predators and sideways in ducks. The feathers are outgrowths of the epidermis and are found in localized bands from where they fan out over the skin. Large flight feathers are found on the wings and tail, contour feathers cover the bird's surface and fine down occurs on young birds and under the contour feathers of water birds. The only cutaneous gland is the single uropygial gland near the base of the tail. This produces an oily secretion that waterproofs the feathers when the bird preens. There are scales on the legs, feet and claws on the tips of the toes. Mammal anatomy Mammals are a diverse class of animals, mostly terrestrial but some are aquatic and others have evolved flapping or gliding flight. They mostly have four limbs, but some aquatic mammals have no limbs or limbs modified into fins, and the forelimbs of bats are modified into wings. The legs of most mammals are situated below the trunk, which is held well clear of the ground. The bones of mammals are well ossified and their teeth, which are usually differentiated, are coated in a layer of prismatic enamel. The teeth are shed once (milk teeth) during the animal's lifetime or not at all, as is the case in cetaceans. Mammals have three bones in the middle ear and a cochlea in the inner ear. They are clothed in hair and their skin contains glands which secrete sweat. Some of these glands are specialized as mammary glands, producing milk to feed the young. Mammals breathe with lungs and have a muscular diaphragm separating the thorax from the abdomen which helps them draw air into the lungs. The mammalian heart has four chambers, and oxygenated and deoxygenated blood are kept entirely separate. Nitrogenous waste is excreted primarily as urea. Mammals are amniotes, and most are viviparous, giving birth to live young. Exceptions to this are the egg-laying monotremes, the platypus and the echidnas of Australia. Most other mammals have a placenta through which the developing foetus obtains nourishment, but in marsupials, the foetal stage is very short and the immature young is born and finds its way to its mother's pouch where it latches on to a nipple and completes its development. Human anatomy Humans have the overall body plan of a mammal. Humans have a head, neck, trunk (which includes the thorax and abdomen), two arms and hands, and two legs and feet. Generally, students of certain biological sciences, paramedics, prosthetists and orthotists, physiotherapists, occupational therapists, nurses, podiatrists, and medical students learn gross anatomy and microscopic anatomy from anatomical models, skeletons, textbooks, diagrams, photographs, lectures and tutorials and in addition, medical students generally also learn gross anatomy through practical experience of dissection and inspection of cadavers. The study of microscopic anatomy (or histology) can be aided by practical experience examining histological preparations (or slides) under a microscope. Human anatomy, physiology and biochemistry are complementary basic medical sciences, which are generally taught to medical students in their first year at medical school. Human anatomy can be taught regionally or systemically; that is, respectively, studying anatomy by bodily regions such as the head and chest, or studying by specific systems, such as the nervous or respiratory systems. The major anatomy textbook, Gray's Anatomy, has been reorganized from a systems format to a regional format, in line with modern teaching methods. A thorough working knowledge of anatomy is required by physicians, especially surgeons and doctors working in some diagnostic specialties, such as histopathology and radiology. Academic anatomists are usually employed by universities, medical schools or teaching hospitals. They are often involved in teaching anatomy, and research into certain systems, organs, tissues or cells. Invertebrate anatomy Invertebrates constitute a vast array of living organisms ranging from the simplest unicellular eukaryotes such as Paramecium to such complex multicellular animals as the octopus, lobster and dragonfly. They constitute about 95% of the animal species. By definition, none of these creatures has a backbone. The cells of single-cell protozoans have the same basic structure as those of multicellular animals but some parts are specialized into the equivalent of tissues and organs. Locomotion is often provided by cilia or flagella or may proceed via the advance of pseudopodia, food may be gathered by phagocytosis, energy needs may be supplied by photosynthesis and the cell may be supported by an endoskeleton or an exoskeleton. Some protozoans can form multicellular colonies. Metazoans are a multicellular organism, with different groups of cells serving different functions. The most basic types of metazoan tissues are epithelium and connective tissue, both of which are present in nearly all invertebrates. The outer surface of the epidermis is normally formed of epithelial cells and secretes an extracellular matrix which provides support to the organism. An endoskeleton derived from the mesoderm is present in echinoderms, sponges and some cephalopods. Exoskeletons are derived from the epidermis and is composed of chitin in arthropods (insects, spiders, ticks, shrimps, crabs, lobsters). Calcium carbonate constitutes the shells of molluscs, brachiopods and some tube-building polychaete worms and silica forms the exoskeleton of the microscopic diatoms and radiolaria. Other invertebrates may have no rigid structures but the epidermis may secrete a variety of surface coatings such as the pinacoderm of sponges, the gelatinous cuticle of cnidarians (polyps, sea anemones, jellyfish) and the collagenous cuticle of annelids. The outer epithelial layer may include cells of several types including sensory cells, gland cells and stinging cells. There may also be protrusions such as microvilli, cilia, bristles, spines and tubercles. Marcello Malpighi, the father of microscopical anatomy, discovered that plants had tubules similar to those he saw in insects like the silk worm. He observed that when a ring-like portion of bark was removed on a trunk a swelling occurred in the tissues above the ring, and he unmistakably interpreted this as growth stimulated by food coming down from the leaves, and being captured above the ring. Arthropod anatomy Arthropods comprise the largest phylum in the animal kingdom with over a million known invertebrate species. Insects possess segmented bodies supported by a hard-jointed outer covering, the exoskeleton, made mostly of chitin. The segments of the body are organized into three distinct parts, a head, a thorax and an abdomen. The head typically bears a pair of sensory antennae, a pair of compound eyes, one to three simple eyes (ocelli) and three sets of modified appendages that form the mouthparts. The thorax has three pairs of segmented legs, one pair each for the three segments that compose the thorax and one or two pairs of wings. The abdomen is composed of eleven segments, some of which may be fused and houses the digestive, respiratory, excretory and reproductive systems. There is considerable variation between species and many adaptations to the body parts, especially wings, legs, antennae and mouthparts. Spiders a class of arachnids have four pairs of legs; a body of two segments—a cephalothorax and an abdomen. Spiders have no wings and no antennae. They have mouthparts called chelicerae which are often connected to venom glands as most spiders are venomous. They have a second pair of appendages called pedipalps attached to the cephalothorax. These have similar segmentation to the legs and function as taste and smell organs. At the end of each male pedipalp is a spoon-shaped cymbium that acts to support the copulatory organ. Other branches of anatomy Superficial or surface anatomy is important as the study of anatomical landmarks that can be readily seen from the exterior contours of the body. It enables physicians or veterinary surgeons to gauge the position and anatomy of the associated deeper structures. Superficial is a directional term that indicates that structures are located relatively close to the surface of the body. Comparative anatomy relates to the comparison of anatomical structures (both gross and microscopic) in different animals. Artistic anatomy relates to anatomic studies for artistic reasons. History Ancient In 1600 BCE, the Edwin Smith Papyrus, an Ancient Egyptian medical text, described the heart, its vessels, liver, spleen, kidneys, hypothalamus, uterus and bladder, and showed the blood vessels diverging from the heart. The Ebers Papyrus () features a "treatise on the heart", with vessels carrying all the body's fluids to or from every member of the body. Ancient Greek anatomy and physiology underwent great changes and advances throughout the early medieval world. Over time, this medical practice expanded by a continually developing understanding of the functions of organs and structures in the body. Phenomenal anatomical observations of the human body were made, which have contributed towards the understanding of the brain, eye, liver, reproductive organs and the nervous system. The Hellenistic Egyptian city of Alexandria was the stepping-stone for Greek anatomy and physiology. Alexandria not only housed the biggest library for medical records and books of the liberal arts in the world during the time of the Greeks, but was also home to many medical practitioners and philosophers. Great patronage of the arts and sciences from the Ptolemy rulers helped raise Alexandria up, further rivalling the cultural and scientific achievements of other Greek states. Some of the most striking advances in early anatomy and physiology took place in Hellenistic Alexandria. Two of the most famous anatomists and physiologists of the third century were Herophilus and Erasistratus. These two physicians helped pioneer human dissection for medical research, using the cadavers of condemned criminals, which was considered taboo until the Renaissance—Herophilus was recognized as the first person to perform systematic dissections. Herophilus became known for his anatomical works making impressing contributions to many branches of anatomy and many other aspects of medicine. Some of the works included classifying the system of the pulse, the discovery that human arteries had thicker walls than veins, and that the atria were parts of the heart. Herophilus's knowledge of the human body has provided vital input towards understanding the brain, eye, liver, reproductive organs and nervous system, and characterizing the course of disease. Erasistratus accurately described the structure of the brain, including the cavities and membranes, and made a distinction between its cerebrum and cerebellum During his study in Alexandria, Erasistratus was particularly concerned with studies of the circulatory and nervous systems. He was able to distinguish the sensory and the motor nerves in the human body and believed that air entered the lungs and heart, which was then carried throughout the body. His distinction between the arteries and veins—the arteries carrying the air through the body, while the veins carried the blood from the heart was a great anatomical discovery. Erasistratus was also responsible for naming and describing the function of the epiglottis and the valves of the heart, including the tricuspid. During the third century, Greek physicians were able to differentiate nerves from blood vessels and tendons and to realize that the nerves convey neural impulses. It was Herophilus who made the point that damage to motor nerves induced paralysis. Herophilus named the meninges and ventricles in the brain, appreciated the division between cerebellum and cerebrum and recognized that the brain was the "seat of intellect" and not a "cooling chamber" as propounded by Aristotle Herophilus is also credited with describing the optic, oculomotor, motor division of the trigeminal, facial, vestibulocochlear and hypoglossal nerves. Great feats were made during the third century BCE in both the digestive and reproductive systems. Herophilus was able to discover and describe not only the salivary glands, but the small intestine and liver. He showed that the uterus is a hollow organ and described the ovaries and uterine tubes. He recognized that spermatozoa were produced by the testes and was the first to identify the prostate gland. The anatomy of the muscles and skeleton is described in the Hippocratic Corpus, an Ancient Greek medical work written by unknown authors. Aristotle described vertebrate anatomy based on animal dissection. Praxagoras identified the difference between arteries and veins. Also in the 4th century BCE, Herophilos and Erasistratus produced more accurate anatomical descriptions based on vivisection of criminals in Alexandria during the Ptolemaic dynasty. In the 2nd century, Galen of Pergamum, an anatomist, clinician, writer and philosopher, wrote the final and highly influential anatomy treatise of ancient times. He compiled existing knowledge and studied anatomy through dissection of animals. He was one of the first experimental physiologists through his vivisection experiments on animals. Galen's drawings, based mostly on dog anatomy, became effectively the only anatomical textbook for the next thousand years. His work was known to Renaissance doctors only through Islamic Golden Age medicine until it was translated from the Greek some time in the 15th century. Medieval to early modern Anatomy developed little from classical times until the sixteenth century; as the historian Marie Boas writes, "Progress in anatomy before the sixteenth century is as mysteriously slow as its development after 1500 is startlingly rapid". Between 1275 and 1326, the anatomists Mondino de Luzzi, Alessandro Achillini and Antonio Benivieni at Bologna carried out the first systematic human dissections since ancient times. Mondino's Anatomy of 1316 was the first textbook in the medieval rediscovery of human anatomy. It describes the body in the order followed in Mondino's dissections, starting with the abdomen, then the thorax, then the head and limbs. It was the standard anatomy textbook for the next century. Leonardo da Vinci (1452–1519) was trained in anatomy by Andrea del Verrocchio. He made use of his anatomical knowledge in his artwork, making many sketches of skeletal structures, muscles and organs of humans and other vertebrates that he dissected. Andreas Vesalius (1514–1564), professor of anatomy at the University of Padua, is considered the founder of modern human anatomy. Originally from Brabant, Vesalius published the influential book De humani corporis fabrica ("the structure of the human body"), a large format book in seven volumes, in 1543. The accurate and intricately detailed illustrations, often in allegorical poses against Italianate landscapes, are thought to have been made by the artist Jan van Calcar, a pupil of Titian. In England, anatomy was the subject of the first public lectures given in any science; these were given by the Company of Barbers and Surgeons in the 16th century, joined in 1583 by the Lumleian lectures in surgery at the Royal College of Physicians. Late modern In the United States, medical schools began to be set up towards the end of the 18th century. Classes in anatomy needed a continual stream of cadavers for dissection and these were difficult to obtain. Philadelphia, Baltimore and New York were all renowned for body snatching activity as criminals raided graveyards at night, removing newly buried corpses from their coffins. A similar problem existed in Britain where demand for bodies became so great that grave-raiding and even anatomy murder were practised to obtain cadavers. Some graveyards were in consequence protected with watchtowers. The practice was halted in Britain by the Anatomy Act of 1832, while in the United States, similar legislation was enacted after the physician William S. Forbes of Jefferson Medical College was found guilty in 1882 of "complicity with resurrectionists in the despoliation of graves in Lebanon Cemetery". The teaching of anatomy in Britain was transformed by Sir John Struthers, Regius Professor of Anatomy at the University of Aberdeen from 1863 to 1889. He was responsible for setting up the system of three years of "pre-clinical" academic teaching in the sciences underlying medicine, including especially anatomy. This system lasted until the reform of medical training in 1993 and 2003. As well as teaching, he collected many vertebrate skeletons for his museum of comparative anatomy, published over 70 research papers, and became famous for his public dissection of the Tay Whale. From 1822 the Royal College of Surgeons regulated the teaching of anatomy in medical schools. Medical museums provided examples in comparative anatomy, and were often used in teaching. Ignaz Semmelweis investigated puerperal fever and he discovered how it was caused. He noticed that the frequently fatal fever occurred more often in mothers examined by medical students than by midwives. The students went from the dissecting room to the hospital ward and examined women in childbirth. Semmelweis showed that when the trainees washed their hands in chlorinated lime before each clinical examination, the incidence of puerperal fever among the mothers could be reduced dramatically. Before the modern medical era, the main means for studying the internal structures of the body were dissection of the dead and inspection, palpation and auscultation of the living. It was the advent of microscopy that opened up an understanding of the building blocks that constituted living tissues. Technical advances in the development of achromatic lenses increased the resolving power of the microscope and around 1839, Matthias Jakob Schleiden and Theodor Schwann identified that cells were the fundamental unit of organization of all living things. Study of small structures involved passing light through them and the microtome was invented to provide sufficiently thin slices of tissue to examine. Staining techniques using artificial dyes were established to help distinguish between different types of tissue. Advances in the fields of histology and cytology began in the late 19th century along with advances in surgical techniques allowing for the painless and safe removal of biopsy specimens. The invention of the electron microscope brought a great advance in resolution power and allowed research into the ultrastructure of cells and the organelles and other structures within them. About the same time, in the 1950s, the use of X-ray diffraction for studying the crystal structures of proteins, nucleic acids and other biological molecules gave rise to a new field of molecular anatomy. Equally important advances have occurred in non-invasive techniques for examining the interior structures of the body. X-rays can be passed through the body and used in medical radiography and fluoroscopy to differentiate interior structures that have varying degrees of opaqueness. Magnetic resonance imaging, computed tomography, and ultrasound imaging have all enabled examination of internal structures in unprecedented detail to a degree far beyond the imagination of earlier generations.

Affirming the consequent

Affirming the consequent, sometimes called converse error, fallacy of the converse, or confusion of necessity and sufficiency, is a formal fallacy of taking a true conditional statement (e.g., "If the lamp were broken, then the room would be dark"), and invalidly inferring its converse ("The room is dark, so the lamp is broken"), even though that statement may not be true. This arises when a consequent ("the room would be dark") has other possible antecedents (for example, "the lamp is in working order, but is switched off" or "there is no lamp in the room"). Converse errors are common in everyday thinking and communication and can result from, among other causes, communication issues, misconceptions about logic, and failure to consider other causes. The opposite statement, denying the consequent, is a valid form of argument (modus tollens). Formal description Affirming the consequent is the action of taking a true statement and invalidly concluding its converse . The name affirming the consequent derives from using the consequent, Q, of , to conclude the antecedent P. This fallacy can be summarized formally as or, alternatively, . The root cause of such a logical error is sometimes failure to realize that just because P is a possible condition for Q, P may not be the only condition for Q, i.e. Q may follow from another condition as well. Affirming the consequent can also result from overgeneralizing the experience of many statements having true converses. If P and Q are "equivalent" statements, i.e. , it is possible to infer P under the condition Q. For example, the statements "It is August 13, so it is my birthday" and "It is my birthday, so it is August 13" are equivalent and both true consequences of the statement "August 13 is my birthday" (an abbreviated form of ). Of the possible forms of "mixed hypothetical syllogisms," two are valid and two are invalid. Affirming the antecedent (modus ponens) and denying the consequent (modus tollens) are valid. Affirming the consequent and denying the antecedent are invalid(see table). Additional examples Example 1 One way to demonstrate the invalidity of this argument form is with a counterexample with true premises but an obviously false conclusion. For example: If someone lives in San Diego, then they live in California. Joe lives in California. Therefore, Joe lives in San Diego. There are many ways to live in California without living in San Diego, as long as they live in a Californian place other than San Diego. However, one can affirm with certainty that "if someone does not live in California" (non-Q), then "this person does not live in San Diego" (non-P). This is the contrapositive of the first statement, and it must be true if and only if the original statement is true. Example 2 Here is another useful, obviously fallacious example. If an animal is a dog, then it has four legs. My cat has four legs. Therefore, my cat is a dog. Here, it is immediately intuitive that any number of other antecedents ("If an animal is a deer...", "If an animal is an elephant...", "If an animal is a moose...", etc.) can give rise to the consequent ("then it has four legs"), and that it is preposterous to suppose that having four legs must imply that the animal is a dog and nothing else. This is useful as a teaching example since most people can immediately recognize that the conclusion reached must be wrong (intuitively, a cat cannot be a dog), and that the method by which it was reached must therefore be fallacious. Example 3 Arguments of the same form can sometimes seem superficially convincing, as in the following example: If Brian had been thrown off the top of the Eiffel Tower, then he would be dead. Brian is dead. Therefore, Brian was thrown off the top of the Eiffel Tower. Being thrown off the top of the Eiffel Tower is not the only cause of death, since there exist numerous different causes of death. Example 4 In Catch-22, the chaplain is interrogated for supposedly being "Washington Irving"/"Irving Washington", who has been blocking out large portions of soldiers' letters home. The colonel has found such a letter, but with the Chaplain's name signed. "You can read, though, can't you?" the colonel persevered sarcastically. "The author signed his name." "That's my name there." "Then you wrote it. Q.E.D." P in this case is 'The chaplain signs his own name', and Q 'The chaplain's name is written'. The chaplain's name may be written, but he did not necessarily write it, as the colonel falsely concludes.Example 5 When teaching the scientific method, the following example is used to illustrate why, via the fallacy of affirming the consequent, no scientific theory is ever proven true but rather simply failed to be falsified. If this theory is correct, we will observe X. We observe X. Therefore, this theory is correct. Concluding or assuming that a theory is true because of a prediction it makes being observed is invalid. This is one of the challenges of applying the scientific method though rarely is it brought up in academic contexts as it is unlikely to be of consequence to the results of the study. Much more common is questioning the validity of the theory, the validity of expected the theory to have predicted the observation, and/or the validity of the observation itself.

Andrei Tarkovsky

Andrei Arsenyevich Tarkovsky (; 4 April 1932 – 29 December 1986) was a Russian filmmaker. Widely considered one of the greatest and most influential directors in cinema history, his films explore spiritual and metaphysical themes, and are noted for their slow pacing and long takes, dreamlike visual imagery, and preoccupation with nature and memory. Tarkovsky studied film at Moscow's VGIK under filmmaker Mikhail Romm, and subsequently directed his first five features in the Soviet Union: Ivan's Childhood (1962), Andrei Rublev (1966), Solaris (1972), Mirror (1975), and Stalker (1979). A number of his films from this period are ranked among the best films ever made. After years of creative conflict with state film authorities, Tarkovsky left the country in 1979 and made his final two films abroad; Nostalghia (1983) and The Sacrifice (1986) were produced in Italy and Sweden respectively. In 1986, he also published a book about cinema and art entitled Sculpting in Time. He died later that year of cancer, a condition possibly caused by the toxic locations used in the filming of Stalker. Tarkovsky was the recipient of several awards at the Cannes Film Festival throughout his career (including the FIPRESCI prize, the Prize of the Ecumenical Jury, and the Grand Prix Spécial du Jury and winner of the Golden Lion award at the Venice Film Festival for his debut film Ivan's Childhood. In 1990, he was posthumously awarded the Soviet Union's prestigious Lenin Prize. Three of his films—Andrei Rublev, Mirror, and Stalker—featured in Sight & Sound 2012 poll of the 100 greatest films of all time. Life and career Childhood and early life Andrei Tarkovsky was born in the village of Zavrazhye in the Yuryevetsky District of the Ivanovo Industrial Oblast (modern-day Kadyysky District of the Kostroma Oblast, Russia) to the poet and translator Arseny Aleksandrovich Tarkovsky, a native of Yelysavethrad (now Kropyvnytskyi, Ukraine), and Maria Ivanova Vishnyakova, a graduate of the Maxim Gorky Literature Institute who later worked as a proofreader; she was born in Moscow in the Dubasov family estate. Andrei's paternal grandfather Aleksandr Karlovich Tarkovsky (in ) was a Polish nobleman who worked as a bank clerk. His wife Maria Danilovna Rachkovskaya was a Romanian language teacher who arrived from Iași. Andrei's maternal grandmother Vera Nikolayevna Vishnyakova (née Dubasova) belonged to an old Dubasov family of Russian nobility that traces its history back to the 17th century; among her relatives was Admiral Fyodor Dubasov, a fact she had to conceal during the Soviet days. She was married to Ivan Ivanovich Vishnyakov, a native of the Kaluga Governorate who studied law at the Moscow State University and served as a judge in Kozelsk. According to the family legend, Tarkovsky's ancestors on his father's side were princes from the Shamkhalate of Tarki, Dagestan, although his sister Marina Tarkovskaya who did a detailed research on their genealogy called it "a myth, even a prank of sorts," stressing that none of the documents confirms this version. Tarkovsky spent his childhood in Yuryevets. He was described by childhood friends as active and popular, having many friends and being typically in the center of action. His father left the family in 1937, subsequently volunteering for the army in 1941. He returned home in 1943, having been awarded a Red Star after being shot in one of his legs (which he would eventually need to amputate due to gangrene). Tarkovsky stayed with his mother, moving with her and his sister Marina to Moscow, where she worked as a proofreader at a printing press. In 1939, Tarkovsky enrolled at the Moscow School No. 554. During the war, the three evacuated to Yuryevets, living with his maternal grandmother. In 1943, the family returned to Moscow. Tarkovsky continued his studies at his old school, where the poet Andrei Voznesensky was one of his classmates. He studied piano at a music school and attended classes at an art school. The family lived on Shchipok Street in the Zamoskvorechye District in Moscow. From November 1947 to spring 1948 he was in the hospital with tuberculosis. Many themes of his childhood—the evacuation, his mother and her two children, the withdrawn father, the time in the hospital—feature prominently in his film Mirror. In his school years, Tarkovsky was a troublemaker and a poor student. He still managed to graduate, and from 1951 to 1952 studied Arabic at the Oriental Institute in Moscow, a branch of the Academy of Sciences of the Soviet Union. Although he already spoke some Arabic and was a successful student in his first semesters, he did not finish his studies and dropped out to work as a prospector for the Academy of Science Institute for Non-Ferrous Metals and Gold. He participated in a year-long research expedition to the river Kureyka near Turukhansk in the Krasnoyarsk Province. During this time in the taiga, Tarkovsky decided to study film. Film school student Upon returning from the research expedition in 1954, Tarkovsky applied at the State Institute of Cinematography (VGIK) and was admitted to the film-directing program. He was in the same class as Irma Raush (Irina) whom he married in April 1957. The early Khrushchev era offered good opportunities for young film directors. Before 1953, annual film production was low and most films were directed by veteran directors. After 1953, more films were produced, many of them by young directors. The Khrushchev Thaw relaxed Soviet social restrictions a bit and permitted a limited influx of European and North American literature, films and music. This allowed Tarkovsky to see films of the Italian neorealists, French New Wave, and of directors such as Kurosawa, Buñuel, Bergman, Bresson, Wajda (whose film Ashes and Diamonds influenced Tarkovsky) and Mizoguchi. Tarkovsky's teacher and mentor was Mikhail Romm, who taught many film students who would later become influential film directors. In 1956, Tarkovsky directed his first student short film, The Killers, from a short story of Ernest Hemingway. The longer television film There Will Be No Leave Today followed in 1959. Both films were a collaboration between the VGIK students. Classmate Aleksandr Gordon, who married Tarkovsky's sister, in particular directed, wrote, edited, and acted in the two films with Tarkovsky. An important influence on Tarkovsky was the film director Grigory Chukhray, who was teaching at the VGIK. Impressed by the talent of his student, Chukhray offered Tarkovsky a position as assistant director for his film Clear Skies. Tarkovsky initially showed interest but then decided to concentrate on his studies and his own projects. During his third year at the VGIK, Tarkovsky met Andrei Konchalovsky. They found much in common as they liked the same film directors and shared ideas on cinema and films. In 1959, they wrote the script Antarctica – Distant Country, which was later published in the Moskovsky Komsomolets. Tarkovsky submitted the script to Lenfilm, but it was rejected. They were more successful with the script The Steamroller and the Violin, which they sold to Mosfilm. This became Tarkovsky's graduation project, earning him his diploma in 1960 and winning First Prize at the New York Student Film Festival in 1961. Film career in the Soviet Union Tarkovsky's first feature film was Ivan's Childhood in 1962. He had inherited the film from director Eduard Abalov, who had to abort the project. The film earned Tarkovsky international acclaim and won the Golden Lion award at the Venice Film Festival in the year 1962. In the same year, on 30 September, his first son Arseny (called Senka in Tarkovsky's diaries) Tarkovsky was born. In 1965, he directed the film Andrei Rublev about the life of Andrei Rublev, the fifteenth-century Russian icon painter. Andrei Rublev was not, except for a single screening in Moscow in 1966, immediately released after completion due to problems with Soviet authorities. Tarkovsky had to cut the film several times, resulting in several different versions of varying lengths. The film was widely released in the Soviet Union in a cut version in 1971. Nevertheless, the film had a budget of more than 1 million rubles – a significant sum for that period. A version of the film was presented at the Cannes Film Festival in 1969 and won the FIPRESCI prize. He divorced his wife, Irina, in June 1970. In the same year, he married Larisa Kizilova (née Egorkina), who had been a production assistant for the film Andrei Rublev (they had been living together since 1965). Their son, Andrei Andreyevich Tarkovsky, (nicknamed Andriosha, meaning "little Andre" or "Andre Junior") was born in the same year on 7 August. In 1972, he completed Solaris, an adaptation of the novel Solaris by Stanisław Lem. He had worked on this together with screenwriter Friedrich Gorenstein as early as 1968. The film was presented at the Cannes Film Festival, won the Grand Prix Spécial du Jury, and was nominated for the Palme d'Or. From 1973 to 1974, he shot the film Mirror, a highly autobiographical and unconventionally structured film drawing on his childhood and incorporating some of his father's poems. In this film Tarkovsky portrayed the plight of childhood affected by war. Tarkovsky had worked on the screenplay for this film since 1967, under the consecutive titles Confession, White day and A white, white day. From the beginning the film was not well received by Soviet authorities due to its content and its perceived elitist nature. Soviet authorities placed the film in the "third category", a severely limited distribution, and only allowed it to be shown in third-class cinemas and workers' clubs. Few prints were made and the film-makers received no returns. Third category films also placed the film-makers in danger of being accused of wasting public funds, which could have serious effects on their future productivity. These difficulties are presumed to have made Tarkovsky play with the idea of going abroad and producing a film outside the Soviet film industry. During 1975, Tarkovsky also worked on the screenplay Hoffmanniana, about the German writer and poet E. T. A. Hoffmann. In December 1976, he directed Hamlet, his only stage play, at the Lenkom Theatre in Moscow. The main role was played by Anatoly Solonitsyn, who also acted in several of Tarkovsky's films. At the end of 1978, he also wrote the screenplay Sardor together with the writer Aleksandr Misharin. The last film Tarkovsky completed in the Soviet Union was Stalker, inspired by the novel Roadside Picnic by the brothers Arkady and Boris Strugatsky. Tarkovsky had met the brothers first in 1971 and was in contact with them until his death in 1986. Initially he wanted to shoot a film based on their novel Dead Mountaineer's Hotel and he developed a raw script. Influenced by a discussion with Arkady Strugatsky he changed his plan and began to work on the script based on Roadside Picnic. Work on this film began in 1976. The production was mired in troubles; improper development of the negatives had ruined all the exterior shots. Tarkovsky's relationship with cinematographer Georgy Rerberg deteriorated to the point where he hired Alexander Knyazhinsky as a new first cinematographer. Furthermore, Tarkovsky had a heart attack in April 1978, resulting in further delay. The film was completed in 1979 and won the Prize of the Ecumenical Jury at the Cannes Film Festival. In a question and answer session at the Edinburgh Filmhouse on 11 February 1981, Tarkovsky trenchantly rejected suggestions that the film was either impenetrably mysterious or a political allegory. In 1979, Tarkovsky began production of the film The First Day (Russian: Первый День Pervyj Dyen), based on a script by his friend and long-term collaborator Andrei Konchalovsky. The film was set in 18th-century Russia during the reign of Peter the Great and starred Natalya Bondarchuk and Anatoli Papanov. To get the project approved by Goskino, Tarkovsky submitted a script that was different from the original script, omitting several scenes that were critical of the official atheism in the Soviet Union. After shooting roughly half of the film the project was stopped by Goskino after it became apparent that the film differed from the script submitted to the censors. Tarkovsky was reportedly infuriated by this interruption and destroyed most of the film. Film career outside the Soviet Union During the summer of 1979, Tarkovsky traveled to Italy, where he shot the documentary Voyage in Time together with his long-time friend Tonino Guerra. Tarkovsky returned to Italy in 1980 for an extended trip, during which he and Guerra completed the script for the film Nostalghia. During this period, he took Polaroid photographs depicting his personal life. Tarkovsky returned to Italy in 1982 to start shooting Nostalghia, but Mosfilm then withdrew from the project, so he sought and received financial backing from the Italian RAI. Tarkovsky completed the film in 1983, and it was presented at the Cannes Film Festival where it won the FIPRESCI prize and the Prize of the Ecumenical Jury. Tarkovsky also shared a special prize called Grand Prix du cinéma de creation with Robert Bresson. Soviet authorities lobbied to prevent the film from winning the Palme d'Or, a fact that hardened Tarkovsky's resolve to never work in the Soviet Union again. After Cannes he went to London to stage and choreograph the opera Boris Godunov at the Royal Opera House under the musical direction of Claudio Abbado. At a press conference in Milan on 10 July 1984, he announced that he would never return to the Soviet Union and would remain in Western Europe. He stated, "I am not a Soviet dissident, I have no conflict with the Soviet Government," but if he returned home, he added, "I would be unemployed." At that time, his son Andriosha was still in the Soviet Union and not allowed to leave the country. On 28 August 1985, Tarkovsky was processed as a Soviet Defector at a refugee camp in Latina, Italy, registered with the serial number 13225/379, and officially welcomed to the West. Tarkovsky spent most of 1984 preparing the film The Sacrifice. It was finally shot in 1985 in Sweden, with many of the crew being alumni from Ingmar Bergman's films, including cinematographer Sven Nykvist. Tarkovsky's vision of his film was greatly influenced by Bergman's style. While The Sacrifice is about an apocalypse and impending death, faith, and possible redemption, in the making-of documentary Directed by Andrei Tarkovsky, in a particularly poignant scene, writer/director Michal Leszczylowski follows Tarkovsky on a walk as he expresses his sentiments on death—he claims himself to be immortal and has no fear of dying. Ironically, at the end of the year Tarkovsky was diagnosed with terminal lung cancer. In January 1986, he began treatment in Paris and was joined there by his son, Andre Jr, who was finally allowed to leave the Soviet Union. What would be Tarkovsky's final film was dedicated to him. The Sacrifice was presented at the Cannes Film Festival and received the Grand Prix Spécial du Jury, the FIPRESCI prize and the Prize of the Ecumenical Jury. As Tarkovsky was unable to attend due to his illness, the prizes were collected by his son. Death In Tarkovsky's last diary entry (15 December 1986), he wrote: "But now I have no strength left—that is the problem". The diaries are sometimes also known as Martyrology and were published posthumously in 1989 and in English in 1991. Tarkovsky died in Paris on 29 December 1986. His funeral ceremony was held at the Alexander Nevsky Cathedral. He was buried on 3 January 1987 in the Russian Cemetery in Sainte-Geneviève-des-Bois in France. The inscription on his gravestone, which was erected in 1994, was conceived by Tarkovsky's wife, Larisa, reads: To the man who saw the Angel. Larisa died in 1998 and is buried beside her husband. A conspiracy theory emerged in Russia in the early 1990s when it was alleged that Tarkovsky did not die of natural causes, but was assassinated by the KGB. Evidence for this hypothesis includes testimonies by former KGB agents who claim that Viktor Chebrikov gave the order to eradicate Tarkovsky to curtail what the Soviet government and the KGB saw as anti-Soviet propaganda by Tarkovsky. Other evidence includes several memoranda that surfaced after the 1991 coup and the claim by one of Tarkovsky's doctors that his cancer could not have developed from a natural cause. As with Tarkovsky, his wife Larisa and actor Anatoly Solonitsyn all died from the very same type of lung cancer. Vladimir Sharun, sound designer in Stalker, is convinced that they were all poisoned by the chemical plant where they were shooting the film. Influences Tarkovsky became a film director during the mid and late 1950s, a period referred to as the Khrushchev Thaw, during which Soviet society opened to foreign films, literature and music, among other things. This allowed Tarkovsky to see films of European, American and Japanese directors, an experience that influenced his own film making. His teacher and mentor at the film school, Mikhail Romm, allowed his students considerable freedom and emphasized the independence of the film director. Tarkovsky was, according to fellow student Shavkat Abdusalmov, fascinated by Japanese films. He was amazed by how every character on the screen is exceptional and how everyday events such as a Samurai cutting bread with his sword are elevated to something special and put into the limelight. Tarkovsky has also expressed interest in the art of Haiku and its ability to create "images in such a way that they mean nothing beyond themselves". Tarkovsky was also a deeply religious Orthodox Christian, who believed great art should have a higher spiritual purpose. He was a perfectionist not given to humor or humility: his signature style was ponderous and literary, having many characters that pondered over religious themes and issues regarding faith. Tarkovsky perceived that the art of cinema has only been truly mastered by very few filmmakers, stating in a 1970 interview with Naum Abramov that "they can be counted on the fingers of one hand". In 1972, Tarkovsky told film historian Leonid Kozlov his ten favorite films. The list includes: Diary of a Country Priest and Mouchette by Robert Bresson; Winter Light, Wild Strawberries, and Persona by Ingmar Bergman; Nazarín by Luis Buñuel; City Lights by Charlie Chaplin; Ugetsu by Kenji Mizoguchi; Seven Samurai by Akira Kurosawa, and Woman in the Dunes by Hiroshi Teshigahara. Among his favorite directors were Buñuel, Mizoguchi, Bergman, Bresson, Kurosawa, Michelangelo Antonioni, Jean Vigo, and Carl Theodor Dreyer. With the exception of City Lights, the list does not contain any films of the early silent era. The reason is that Tarkovsky saw film as an art as only a relatively recent phenomenon, with the early film-making forming only a prelude. The list has also no films or directors from Tarkovsky's native Russia, although he rated Soviet directors such as Boris Barnet, Sergei Parajanov and Alexander Dovzhenko highly. He said of Dovzhenko's Earth: "I have lived a lot among very simple farmers and met extraordinary people. They spread calmness, had such tact, they conveyed a feeling of dignity and displayed wisdom that I have seldom come across on such a scale. Dovzhenko had obviously understood wherein the sense of life resides. [...] This trespassing of the border between nature and mankind is an ideal place for the existence of man. Dovzhenko understood this." Andrei Tarkovsky was not a fan of science fiction, largely dismissing it for its "comic book" trappings and vulgar commercialism. However, in a famous exception Tarkovsky praised the blockbuster film The Terminator, saying that its "vision of the future and the relation between man and its destiny is pushing the frontier of cinema as an art". He was critical of the "brutality and low acting skills", but was nevertheless impressed by the film. Cinematic style In a 1962 interview, Tarkovsky argued: "All art, of course, is intellectual, but for me, all the arts, and cinema even more so, must above all be emotional and act upon the heart." His films are characterized by metaphysical themes, extremely long takes, and images often considered by critics to be of exceptional beauty. Recurring motifs are dreams, memory, childhood, running water accompanied by fire, rain indoors, reflections, levitation, and characters re-appearing in the foreground of long panning movements of the camera. He once said: "Juxtaposing a person with an environment that is boundless, collating him with a countless number of people passing by close to him and far away, relating a person to the whole world, that is the meaning of cinema." Tarkovsky incorporated levitation scenes into several of his films, most notably Solaris. To him these scenes possess great power and are used for their photogenic value and magical inexplicability. Water, clouds, and reflections were used by him for their surreal beauty and photogenic value, as well as their symbolism, such as waves or the forms of brooks or running water. Bells and candles are also frequent symbols. These are symbols of film, sight and sound, and Tarkovsky's film frequently has themes of self-reflection. Tarkovsky developed a theory of cinema that he called "sculpting in time". By this he meant that the unique characteristic of cinema as a medium was to take our experience of time and alter it. Unedited movie footage transcribes time in real time. By using long takes and few cuts in his films, he aimed to give the viewers a sense of time passing, time lost, and the relationship of one moment in time to another. Up to, and including, his film Mirror, Tarkovsky focused his cinematic works on exploring this theory. After Mirror, he announced that he would focus his work on exploring the dramatic unities proposed by Aristotle: a concentrated action, happening in one place, within the span of a single day. Several of Tarkovsky's films have color or black-and-white sequences. This first occurs in the otherwise monochrome Andrei Rublev, which features a color epilogue of Rublev's authentic religious icon paintings. All of his films afterwards contain monochrome, and in Stalker's case sepia sequences, while otherwise being in color. In 1966, in an interview conducted shortly after finishing Andrei Rublev, Tarkovsky dismissed color film as a "commercial gimmick" and cast doubt on the idea that contemporary films meaningfully use color. He claimed that in everyday life one does not consciously notice colors most of the time, and that color should therefore be used in film mainly to emphasize certain moments, but not all the time, as this distracts the viewer. To him, films in color were like moving paintings or photographs, which are too beautiful to be a realistic depiction of life. Director Ingmar Bergman commented on Tarkovsky: Contrarily, however, Bergman conceded the truth in the claim made by a critic who wrote that "with Autumn Sonata Bergman does Bergman", adding: "Tarkovsky began to make Tarkovsky films, and that Fellini began to make Fellini films [...] Buñuel nearly always made Buñuel films." This pastiche of one's own work has been derogatorily termed as "self-karaoke". Vadim Yusov Tarkovsky worked in close collaboration with cinematographer Vadim Yusov from 1958 to 1972, and much of the visual style of Tarkovsky's films can be attributed to this collaboration. Tarkovsky would spend two days preparing for Yusov to film a single long take, and due to the preparation, usually only a single take was needed. Sven Nykvist In his last film, The Sacrifice, Tarkovsky worked with cinematographer Sven Nykvist, who had worked on many films with director Ingmar Bergman. (Nykvist was not alone: several people involved in the production had previously collaborated with Bergman, notably lead actor Erland Josephson, who had also acted for Tarkovsky in Nostalghia.) Nykvist complained that Tarkovsky would frequently look through the camera and even direct actors through it, but ultimately stated that choosing to work with Tarkovsky was one of the best choices he had ever made. Filmography Tarkovsky is mainly known as a film director. During his career he directed seven feature films, as well as three shorts from his time at VGIK. His features are: Ivan's Childhood (1962) Andrei Rublev (1966) Solaris (1972) Mirror (1975) Stalker (1979) Nostalghia (1983) The Sacrifice (1986) He also wrote several screenplays. Furthermore, he directed the play Hamlet for the stage in Moscow, directed the opera Boris Godunov in London, and he directed a radio production of the short story Turnabout by William Faulkner. He also wrote Sculpting in Time, a book on film theory. Tarkovsky's first feature film was Ivan's Childhood in 1962. He then directed Andrei Rublev in 1966, Solaris in 1972, Mirror in 1975 and Stalker in 1979. The documentary Voyage in Time was produced in Italy in 1982, as was Nostalghia in 1983. His last film The Sacrifice was produced in Sweden in 1986. Tarkovsky was personally involved in writing the screenplays for all his films, sometimes with a cowriter. Tarkovsky once said that a director who realizes somebody else's screenplay without being involved in it becomes a mere illustrator, resulting in dead and monotonous films. Published books Sculpting in Time, published in 1986 Time Within Time: The Diaries 1970–1986, published in 1989 A book of 60 photos, Instant Light, Tarkovsky Polaroids, taken by Tarkovsky in Russia and Italy between 1979 and 1984 was published in 2006. The collection was selected by Italian photographer Giovanni Chiaramonte and Tarkovsky's son Andrey A. Tarkovsky. Unproduced screenplays Concentrate Concentrate (, Kontsentrat) is a never-filmed 1958 screenplay by Tarkovsky. The screenplay is based on Tarkovsky's year in the taiga as a member of a research expedition, prior to his enrollment in film school. It's about the leader of a geological expedition, who waits for the boat that brings back the concentrates collected by the expedition. The expedition is surrounded by mystery, and its purpose is a state secret. Although some authors claim that the screenplay was filmed, according to Marina Tarkovskaya, Tarkovsky's sister (and wife of Aleksandr Gordon, a fellow student of Tarkovsky during his film school years) the screenplay was never filmed. Tarkovsky wrote the screenplay during his entrance examination at the State Institute of Cinematography (VGIK) in a single sitting. He earned the highest possible grade, "excellent" () for this work. In 1994, fragments of Concentrate were filmed and used in the documentary Andrei Tarkovsky's Taiga Summer by Marina Tarkovskaya and Aleksandr Gordon. Hoffmanniana Hoffmanniana () is a never-filmed 1974 screenplay by Tarkovsky. The screenplay is based on the life and work of German author E. T. A. Hoffmann. In 1974, an acquaintance from Tallinnfilm approached Tarkovsky to write a screenplay on a German theme. Tarkovsky considered Thomas Mann and E. T. A. Hoffmann, and also thought about Ibsen's Peer Gynt. In the end Tarkovsky signed a contract for a script based on the life and work of Hoffmann. He planned to write the script during the summer of 1974 at his dacha. Writing was not without difficulty, less than a month before the deadline he had not written a single page. He finally finished the project in late 1974 and submitted the final script to Tallinnfilm in October. Although the script was well received by the officials at Tallinnfilm, it was the consensus that no one but Tarkovsky would be able to direct it. The script was sent to Goskino in February 1976, and although approval was granted for proceeding with making the film, the screenplay was never realized. In 1984, during the time of his exile in the West, Tarkovsky revisited the screenplay and made a few changes. He also considered to finally direct a film based on the screenplay but ultimately dropped this idea.

He was also nominated for the Palme d'Or three times. In 1987, the BAFTA Award for Best Foreign Language Film of the British Academy of Film and Television Arts for The Sacrifice. Under the influence of Glasnost and Perestroika, Tarkovsky was finally recognized in the Soviet Union in the Autumn of 1986, shortly before his death, by a retrospective of his films in Moscow. After his death, an entire issue of the film magazine Iskusstvo Kino was devoted to Tarkovsky. In their obituaries, the film committee of the Council of Ministers of the Soviet Union and the Union of Soviet Film Makers expressed their sorrow that Tarkovsky had to spend the last years of his life in exile. Posthumously, he was awarded the Lenin Prize in 1990, one of the highest state honors in the Soviet Union. In 1989, the Andrei Tarkovsky Memorial Prize was established, with its first recipient being the Russian animator Yuri Norstein. In three consecutive events, the Moscow International Film Festival awarded the Andrei Tarkovsky Award in 1993, 1995, and 1997. In 1996, the Andrei Tarkovsky Museum opened in Yuryevets, his childhood town. A minor planet, 3345 Tarkovskij, discovered by Soviet astronomer Lyudmila Karachkina in 1982, has been named after him. Tarkovsky has been the subject of several documentaries. Most notable is the 1988 documentary Moscow Elegy, by Russian film director Alexander Sokurov. Sokurov's own work has been heavily influenced by Tarkovsky. The film consists mostly of narration over stock footage from Tarkovsky's films. Directed by Andrei Tarkovsky is a 1988 documentary film by Michal Leszczylowski, an editor of the film The Sacrifice. Film director Chris Marker produced the television documentary One Day in the Life of Andrei Arsenevich as an homage to Andrei Tarkovsky in 2000. At the entrance to the Gerasimov Institute of Cinematography in Moscow, there is a monument that includes statues of Tarkovsky, Gennady Shpalikov and Vasily Shukshin. Reception and legacy Andrei Tarkovsky and his works have received praise from many filmmakers, critics and thinkers. The Swedish filmmaker Ingmar Bergman was quoted as saying: "Tarkovsky for me is the greatest [of us all], the one who invented a new language, true to the nature of film, as it captures life as a reflection, life as a dream". The Japanese filmmaker Akira Kurosawa remarked on Tarkovsky's films as saying: "His unusual sensitivity is both overwhelming and astounding. It almost reaches a pathological intensity. Probably there is no equal among film directors alive now." Kurosawa also commented: "I love all of Tarkovsky's films. I love his personality and all his works. Every cut from his films is a marvelous image in itself. But the finished image is nothing more than the imperfect accomplishment of his idea. His ideas are only realized in part. And he had to make do with it." The Iranian filmmaker Abbas Kiarostami remarked that: "Tarkovsky's works separate me completely from physical life, and are the most spiritual films I have seen". The Polish filmmaker Krzysztof Kieślowski commented that: "Andrei Tarkovsky was one of the greatest directors of recent years," and regarded Tarkovsky's film, Ivan's Childhood as an influence on his own work. The Turkish filmmaker Nuri Bilge Ceylan when he first discovered the films of Andrei Tarkovsky as a college student unsure of what he wanted to do with his life, he was utterly baffled by the lauded Russian master. He walked out of a screening of Solaris at the halfway point, and stopped a VHS tape of Mirror at a similar juncture. Today, he considers the latter to be the greatest film ever made. "I've seen it maybe 20 times," he says. The Armenian filmmaker Sergei Parajanov remarked that watching Tarkovsky's film, Ivan's Childhood was his main inspiration to become a filmmaker by saying: "I did not know how to do anything and I would not have done anything if there had not been Ivan's Childhood". The Austrian filmmaker Michael Haneke voted for Mirror on his top 10 films in the 2002 Sight & Sound directors' poll and later said that he has seen the picture at least 25 times. The German filmmaker Wim Wenders dedicated his film Wings of Desire to Tarkovsky (along with François Truffaut and Yasujirō Ozu). The French filmmaker Chris Marker directed a documentary film as a homage to Tarkovsky called One Day in the Life of Andrei Arsenevich and used Tarkovsky's concept of "The Zone" (from the film, Stalker) for his 1983 film essay, Sans Soleil. The Greek filmmaker Theo Angelopoulos regarded Tarkovsky's film Stalker as one of the films that influenced him. The Polish filmmaker Andrzej Żuławski remarked that: "If anybody influenced anybody, it’s me being influenced by Tarkovsky, not the reverse." and called Tarkovsky's film Andrei Rublev a "masterpiece". The Greek-Australian filmmaker Alex Proyas was "extremely influenced" by Tarkovsky's work and cited Stalker as one his favorite films. The French philosopher Jean-Paul Sartre highly praised Tarkovsky's film Ivan's Childhood, saying that it was one of the most beautiful films he had ever seen. The Japanese anime filmmaker Mamoru Oshii, known for his works such as Ghost in the Shell was influenced by Tarkovsky. The Indian-born British American novelist Salman Rushdie praised Tarkovsky and his work Solaris by calling it a "a sci-fi masterpiece". Film historian Steven Dillon says that much of subsequent film was deeply influenced by the films of Tarkovsky. Mexican filmmaker Alejandro González Iñarritu is a huge fan of Tarkovsky. He once said in an interview: "Andrei Rublev is maybe my favorite film ever", and in another interview, he added: "I remember, the first time I saw a Tarkovsky film, I was shocked by it. I did not know what to do. I was shocked by it. I was fascinated, because suddenly I realized that film could have so many more layers to it than what I had imagined before". There are many direct references and hidden tributes to Tarkovsky's movies in Iñarritu's 2015 Oscar-winning drama The Revenant. Danish film director Lars von Trier is a fervent admirer of Tarkovsky. He dedicated his 2009 film Antichrist to him, and, while discussing it with critic David Jenkins, asked: "Have you seen Mirror? I was hypnotised! I've seen it 20 times. It's the closest thing I've got to a religion – to me he is a god". Film festival Two film festivals have been named in his honor: International Human Rights Film Festival "Stalker", named after the film held annually in Moscow and regional centres since 1995 International Film Festival "Zerkalo" named after Andrei Tarkovsky (meaning "mirror"), "for fans of intellectual cinema"; also known as Tarkovsky Film festival – Zerkalo, Zerkalo International Film Festival, Andrei Tarkovsky Zerkalo International Film Festival, or simply Zerkalo, The festival is organized by a committee headed by Mikhail Men, governor of Ivanovo Oblast. Sister of Andrei Tarkovsky, Marina Tarkovsky was one of the co-founders and organizers. From 2010 the festival was directed by Pavel Lungin. In 2020, the president of the festival was Russian director Sergei Bodrov. Owing to the COVID-19 pandemic in Russia, the 14th edition was held online in 2020, and appears to be the last one held, .The festival awards a number of prizes, including the Special Award for Contribution to Andrei Tarkovsky's Cinema. Held in Ivanovo since 2007, the festival is held in July each year, with the 16th edition scheduled for 22-27 July, to be held in various cities in the Ivanovo region, with special screenings in Moscow. Films from France, India, Greece, Serbia, Colombia, Kazakhstan and other countries were entered into the competition, and a gala night was dedicated to Tarkovsky's 90th birthday, on the main square of his hometown of Yuryevets on 22 July.

Ambiguity

Ambiguity is the type of meaning in which a phrase, statement or resolution is not explicitly defined, making several interpretations plausible. A common aspect of ambiguity is uncertainty. It is thus an attribute of any idea or statement whose intended meaning cannot be definitively resolved, according to a rule or process with a finite number of steps. (The ambi- part of the term reflects an idea of "two," as in "two meanings.") The concept of ambiguity is generally contrasted with vagueness. In ambiguity, specific and distinct interpretations are permitted (although some may not be immediately obvious), whereas with information that is vague, it is difficult to form any interpretation at the desired level of specificity. Linguistic forms Lexical ambiguity is contrasted with semantic ambiguity. The former represents a choice between a finite number of known and meaningful context-dependent interpretations. The latter represents a choice between any number of possible interpretations, none of which may have a standard agreed-upon meaning. This form of ambiguity is closely related to vagueness. Ambiguity in human language is argued to reflect principles of efficient communication. Languages that communicate efficiently will avoid sending information that is redundant with information provided in the context. This can be shown mathematically to result in a system which is ambiguous when context is neglected. In this way, ambiguity is viewed as a generally useful feature of a linguistic system. Linguistic ambiguity can be a problem in law, because the interpretation of written documents and oral agreements is often of paramount importance. Lexical ambiguity The lexical ambiguity of a word or phrase pertains to its having more than one meaning in the language to which the word belongs. "Meaning" here refers to whatever should be captured by a good dictionary. For instance, the word "bank" has several distinct lexical definitions, including "financial institution" and "edge of a river". Or consider "apothecary". One could say "I bought herbs from the apothecary". This could mean one actually spoke to the apothecary (pharmacist) or went to the apothecary (pharmacy). The context in which an ambiguous word is used often makes it evident which of the meanings is intended. If, for instance, someone says "I buried $100 in the bank", most people would not think someone used a shovel to dig in the mud. However, some linguistic contexts do not provide sufficient information to disambiguate a used word. Lexical ambiguity can be addressed by algorithmic methods that automatically associate the appropriate meaning with a word in context, a task referred to as word-sense disambiguation. The use of multi-defined words requires the author or speaker to clarify their context, and sometimes elaborate on their specific intended meaning (in which case, a less ambiguous term should have been used). The goal of clear concise communication is that the receiver(s) have no misunderstanding about what was meant to be conveyed. An exception to this could include a politician whose "weasel words" and obfuscation are necessary to gain support from multiple constituents with mutually exclusive conflicting desires from their candidate of choice. Ambiguity is a powerful tool of political science. More problematic are words whose senses express closely related concepts. "Good", for example, can mean "useful" or "functional" (That's a good hammer), "exemplary" (She's a good student), "pleasing" (This is good soup), "moral" (a good person versus the lesson to be learned from a story), "righteous", etc. "I have a good daughter" is not clear about which sense is intended. The various ways to apply prefixes and suffixes can also create ambiguity ("unlockable" can mean "capable of being unlocked" or "impossible to lock"). Semantic and syntactic ambiguity Semantic ambiguity occurs when a word, phrase or sentence, taken out of context, has more than one interpretation. In "We saw her duck" (example due to Richard Nordquist), the words "her duck" can refer either to the person's bird (the noun "duck", modified by the possessive pronoun "her"), or to a motion she made (the verb "duck", the subject of which is the objective pronoun "her", object of the verb "saw"). Syntactic ambiguity arises when a sentence can have two (or more) different meanings because of the structure of the sentence—its syntax. This is often due to a modifying expression, such as a prepositional phrase, the application of which is unclear. "He ate the cookies on the couch", for example, could mean that he ate those cookies that were on the couch (as opposed to those that were on the table), or it could mean that he was sitting on the couch when he ate the cookies. "To get in, you will need an entrance fee of $10 or your voucher and your drivers' license." This could mean that you need EITHER ten dollars OR BOTH your voucher and your license. Or it could mean that you need your license AND you need EITHER ten dollars OR a voucher. Only rewriting the sentence, or placing appropriate punctuation can resolve a syntactic ambiguity. For the notion of, and theoretic results about, syntactic ambiguity in artificial, formal languages (such as computer programming languages), see Ambiguous grammar. Usually, semantic and syntactic ambiguity go hand in hand. The sentence "We saw her duck" is also syntactically ambiguous. Conversely, a sentence like "He ate the cookies on the couch" is also semantically ambiguous. Rarely, but occasionally, the different parsings of a syntactically ambiguous phrase result in the same meaning. For example, the command "Cook, cook!" can be parsed as "Cook (noun used as vocative), cook (imperative verb form)!", but also as "Cook (imperative verb form), cook (noun used as vocative)!". It is more common that a syntactically unambiguous phrase has a semantic ambiguity; for example, the lexical ambiguity in "Your boss is a funny man" is purely semantic, leading to the response "Funny ha-ha or funny peculiar?" Spoken language can contain many more types of ambiguities which are called phonological ambiguities, where there is more than one way to compose a set of sounds into words. For example, "ice cream" and "I scream". Such ambiguity is generally resolved according to the context. A mishearing of such, based on incorrectly resolved ambiguity, is called a mondegreen. Philosophy Philosophers (and other users of logic) spend a lot of time and effort searching for and removing (or intentionally adding) ambiguity in arguments because it can lead to incorrect conclusions and can be used to deliberately conceal bad arguments. For example, a politician might say, "I oppose taxes which hinder economic growth", an example of a glittering generality. Some will think they oppose taxes in general because they hinder economic growth. Others may think they oppose only those taxes that they believe will hinder economic growth. In writing, the sentence can be rewritten to reduce possible misinterpretation, either by adding a comma after "taxes" (to convey the first sense) or by changing "which" to "that" (to convey the second sense) or by rewriting it in other ways. The devious politician hopes that each constituent will interpret the statement in the most desirable way, and think the politician supports everyone's opinion. However, the opposite can also be true—an opponent can turn a positive statement into a bad one if the speaker uses ambiguity (intentionally or not). The logical fallacies of amphiboly and equivocation rely heavily on the use of ambiguous words and phrases. In continental philosophy (particularly phenomenology and existentialism), there is much greater tolerance of ambiguity, as it is generally seen as an integral part of the human condition. Martin Heidegger argued that the relation between the subject and object is ambiguous, as is the relation of mind and body, and part and whole. In Heidegger's phenomenology, Dasein is always in a meaningful world, but there is always an underlying background for every instance of signification. Thus, although some things may be certain, they have little to do with Dasein's sense of care and existential anxiety, e.g., in the face of death. In calling his work Being and Nothingness an "essay in phenomenological ontology" Jean-Paul Sartre follows Heidegger in defining the human essence as ambiguous, or relating fundamentally to such ambiguity. Simone de Beauvoir tries to base an ethics on Heidegger's and Sartre's writings (The Ethics of Ambiguity), where she highlights the need to grapple with ambiguity: "as long as there have been philosophers and they have thought, most of them have tried to mask it ... And the ethics which they have proposed to their disciples has always pursued the same goal. It has been a matter of eliminating the ambiguity by making oneself pure inwardness or pure externality, by escaping from the sensible world or being engulfed by it, by yielding to eternity or enclosing oneself in the pure moment." Ethics cannot be based on the authoritative certainty given by mathematics and logic, or prescribed directly from the empirical findings of science. She states: "Since we do not succeed in fleeing it, let us, therefore, try to look the truth in the face. Let us try to assume our fundamental ambiguity. It is in the knowledge of the genuine conditions of our life that we must draw our strength to live and our reason for acting". Other continental philosophers suggest that concepts such as life, nature, and sex are ambiguous. Corey Anton has argued that we cannot be certain what is separate from or unified with something else: language, he asserts, divides what is not, in fact, separate. Following Ernest Becker, he argues that the desire to 'authoritatively disambiguate' the world and existence has led to numerous ideologies and historical events such as genocide. On this basis, he argues that ethics must focus on 'dialectically integrating opposites' and balancing tension, rather than seeking a priori validation or certainty. Like the existentialists and phenomenologists, he sees the ambiguity of life as the basis of creativity. Literature and rhetoric In literature and rhetoric, ambiguity can be a useful tool. Groucho Marx's classic joke depends on a grammatical ambiguity for its humor, for example: "Last night I shot an elephant in my pajamas. How he got in my pajamas, I'll never know". Songs and poetry often rely on ambiguous words for artistic effect, as in the song title "Don't It Make My Brown Eyes Blue" (where "blue" can refer to the color, or to sadness). In the narrative, ambiguity can be introduced in several ways: motive, plot, character. F. Scott Fitzgerald uses the latter type of ambiguity with notable effect in his novel The Great Gatsby. Mathematical notation Mathematical notation, widely used in physics and other sciences, avoids many ambiguities compared to expression in natural language. However, for various reasons, several lexical, syntactic and semantic ambiguities remain. Names of functions The ambiguity in the style of writing a function should not be confused with a multivalued function, which can (and should) be defined in a deterministic and unambiguous way. Several special functions still do not have established notations. Usually, the conversion to another notation requires to scale the argument or the resulting value; sometimes, the same name of the function is used, causing confusions. Examples of such underestablished functions: Sinc function Elliptic integral of the third kind; translating elliptic integral form MAPLE to Mathematica, one should replace the second argument to its square, see Talk:Elliptic integral#List of notations; dealing with complex values, this may cause problems. Exponential integral Hermite polynomial Expressions Ambiguous expressions often appear in physical and mathematical texts. It is common practice to omit multiplication signs in mathematical expressions. Also, it is common to give the same name to a variable and a function, for example, . Then, if one sees , there is no way to distinguish whether it means multiplied by , or function evaluated at argument equal to . In each case of use of such notations, the reader is supposed to be able to perform the deduction and reveal the true meaning. Creators of algorithmic languages try to avoid ambiguities. Many algorithmic languages (C++ and Fortran) require the character * as symbol of multiplication. The Wolfram Language used in Mathematica allows the user to omit the multiplication symbol, but requires square brackets to indicate the argument of a function; square brackets are not allowed for grouping of expressions. Fortran, in addition, does not allow use of the same name (identifier) for different objects, for example, function and variable; in particular, the expression f=f(x) is qualified as an error. The order of operations may depend on the context. In most programming languages, the operations of division and multiplication have equal priority and are executed from left to right. Until the last century, many editorials assumed that multiplication is performed first, for example, is interpreted as ; in this case, the insertion of parentheses is required when translating the formulas to an algorithmic language. In addition, it is common to write an argument of a function without parenthesis, which also may lead to ambiguity. In the scientific journal style, one uses roman letters to denote elementary functions, whereas variables are written using italics. For example, in mathematical journals the expression does not denote the sine function, but the product of the three variables , , , although in the informal notation of a slide presentation it may stand for . Commas in multi-component subscripts and superscripts are sometimes omitted; this is also potentially ambiguous notation. For example, in the notation , the reader can only infer from the context whether it means a single-index object, taken with the subscript equal to product of variables , and , or it is an indication to a trivalent tensor. Examples of potentially confusing ambiguous mathematical expressions An expression such as can be understood to mean either or . Often the author's intention can be understood from the context, in cases where only one of the two makes sense, but an ambiguity like this should be avoided, for example by writing or . The expression means in several texts, though it might be thought to mean , since commonly means . Conversely, might seem to mean , as this exponentiation notation usually denotes function iteration: in general, means . However, for trigonometric and hyperbolic functions, this notation conventionally means exponentiation of the result of function application. The expression can be interpreted as meaning ; however, it is more commonly understood to mean . Notations in quantum optics and quantum mechanics It is common to define the coherent states in quantum optics with and states with fixed number of photons with . Then, there is an "unwritten rule": the state is coherent if there are more Greek characters than Latin characters in the argument, and photon state if the Latin characters dominate. The ambiguity becomes even worse, if is used for the states with certain value of the coordinate, and means the state with certain value of the momentum, which may be used in books on quantum mechanics. Such ambiguities easily lead to confusions, especially if some normalized adimensional, dimensionless variables are used. Expression may mean a state with single photon, or the coherent state with mean amplitude equal to 1, or state with momentum equal to unity, and so on. The reader is supposed to guess from the context. Ambiguous terms in physics and mathematics Some physical quantities do not yet have established notations; their value (and sometimes even dimension, as in the case of the Einstein coefficients), depends on the system of notations. Many terms are ambiguous. Each use of an ambiguous term should be preceded by the definition, suitable for a specific case. Just like Ludwig Wittgenstein states in Tractatus Logico-Philosophicus: "... Only in the context of a proposition has a name meaning." A highly confusing term is gain. For example, the sentence "the gain of a system should be doubled", without context, means close to nothing. It may mean that the ratio of the output voltage of an electric circuit to the input voltage should be doubled. It may mean that the ratio of the output power of an electric or optical circuit to the input power should be doubled. It may mean that the gain of the laser medium should be doubled, for example, doubling the population of the upper laser level in a quasi-two level system (assuming negligible absorption of the ground-state). The term intensity is ambiguous when applied to light. The term can refer to any of irradiance, luminous intensity, radiant intensity, or radiance, depending on the background of the person using the term. Also, confusions may be related with the use of atomic percent as measure of concentration of a dopant, or resolution of an imaging system, as measure of the size of the smallest detail which still can be resolved at the background of statistical noise. See also Accuracy and precision and its talk. The Berry paradox arises as a result of systematic ambiguity in the meaning of terms such as "definable" or "nameable". Terms of this kind give rise to vicious circle fallacies. Other terms with this type of ambiguity are: satisfiable, true, false, function, property, class, relation, cardinal, and ordinal. Mathematical interpretation of ambiguity In mathematics and logic, ambiguity can be considered to be an instance of the logical concept of underdetermination—for example, leaves open what the value of X is—while its opposite is a self-contradiction, also called inconsistency, paradoxicalness, or oxymoron, or in mathematics an inconsistent system—such as , which has no solution. Logical ambiguity and self-contradiction is analogous to visual ambiguity and impossible objects, such as the Necker cube and impossible cube, or many of the drawings of M. C. Escher. Constructed language Some languages have been created with the intention of avoiding ambiguity, especially lexical ambiguity. Lojban and Loglan are two related languages which have been created for this, focusing chiefly on syntactic ambiguity as well. The languages can be both spoken and written. These languages are intended to provide a greater technical precision over big natural languages, although historically, such attempts at language improvement have been criticized. Languages composed from many diverse sources contain much ambiguity and inconsistency. The many exceptions to syntax and semantic rules are time-consuming and difficult to learn. Biology In structural biology, ambiguity has been recognized as a problem for studying protein conformations. The analysis of a protein three-dimensional structure consists in dividing the macromolecule into subunits called domains. The difficulty of this task arises from the fact that different definitions of what a domain is can be used (e.g. folding autonomy, function, thermodynamic stability, or domain motions), which sometimes results in a single protein having different—yet equally valid—domain assignments. Christianity and Judaism Christianity and Judaism employ the concept of paradox synonymously with "ambiguity". Many Christians and Jews endorse Rudolf Otto's description of the sacred as 'mysterium tremendum et fascinans', the awe-inspiring mystery which fascinates humans. The apocryphal Book of Judith is noted for the "ingenious ambiguity" expressed by its heroine e.g. she says to the villain of the story, Holofernes, "my lord will not fail to achieve his purposes". The orthodox Catholic writer G. K. Chesterton regularly employed paradox to tease out the meanings in common concepts which he found ambiguous or to reveal meaning often overlooked or forgotten in common phrases: the title of one of his most famous books, Orthodoxy (1908), itself employed such a paradox. Music In music, pieces or sections which confound expectations and may be or are interpreted simultaneously in different ways are ambiguous, such as some polytonality, polymeter, other ambiguous meters or rhythms, and ambiguous phrasing, or (Stein 2005, p. 79) any aspect of music. The music of Africa is often purposely ambiguous. To quote Sir Donald Francis Tovey (1935, p. 195), "Theorists are apt to vex themselves with vain efforts to remove uncertainty just where it has a high aesthetic value." Visual art In visual art, certain images are visually ambiguous, such as the Necker cube, which can be interpreted in two ways. Perceptions of such objects remain stable for a time, then may flip, a phenomenon called multistable perception. The opposite of such ambiguous images are impossible objects. Pictures or photographs may also be ambiguous at the semantic level: the visual image is unambiguous, but the meaning and narrative may be ambiguous: is a certain facial expression one of excitement or fear, for instance? Social psychology and the bystander effect In social psychology, ambiguity is a factor used in determining peoples' responses to various situations. High levels of ambiguity in an emergency (e.g. an unconscious man lying on a park bench) make witnesses less likely to offer any sort of assistance, due to the fear that they may have misinterpreted the situation and acted unnecessarily. Alternately, non-ambiguous emergencies (e.g. an injured person verbally asking for help) elicit more consistent intervention and assistance. With regard to the bystander effect, studies have shown that emergencies deemed ambiguous trigger the appearance of the classic bystander effect (wherein more witnesses decrease the likelihood of any of them helping) far more than non-ambiguous emergencies. Computer science In computer science, the SI prefixes kilo-, mega- and giga- were historically used in certain contexts to mean either the first three powers of 1024 (1024, 10242 and 10243) contrary to the metric system in which these units unambiguously mean one thousand, one million, and one billion. This usage is particularly prevalent with electronic memory devices (e.g. DRAM) addressed directly by a binary machine register where a decimal interpretation makes no practical sense. Subsequently, the Ki, Mi, and Gi prefixes were introduced so that binary prefixes could be written explicitly, also rendering k, M, and G unambiguous in texts conforming to the new standard—this led to a new ambiguity in engineering documents lacking outward trace of the binary prefixes (necessarily indicating the new style) as to whether the usage of k, M, and G remains ambiguous (old style) or not (new style). 1 M (where M is ambiguously 1,000,000 or 1,048,576) is less uncertain than the engineering value 1.0e6 (defined to designate the interval 950,000 to 1,050,000). As non-volatile storage devices begin to exceed 1 GB in capacity (where the ambiguity begins to routinely impact the second significant digit), GB and TB almost always mean 109 and 1012 bytes.

https://en.wikipedia.org/wiki/Abel

Abel

Abel is a Biblical figure in the Book of Genesis within Abrahamic religions. He was the younger brother of Cain, and the younger son of Adam and Eve, the first couple in Biblical history. He was a shepherd who offered his firstborn flock up to God as an offering. God accepted his offering but not his brother's. Cain then killed Abel out of jealousy. According to Genesis, this was the first murder in the history of mankind. Interpretations Jewish and Christian interpretations According to the narrative in Genesis, Abel ( Hébel, in pausa Hā́ḇel; Hábel; , Hābēl) is Eve's second son. His name in Hebrew is composed of the same three consonants as a root meaning "breath". Julius Wellhausen has proposed that the name is independent of the root. Eberhard Schrader had previously put forward the Akkadian (Old Assyrian dialect) ablu ("son") as a more likely etymology. In Christianity, comparisons are sometimes made between the death of Abel and that of Jesus, the former thus seen as being the first martyr. In Jesus speaks of Abel as "righteous", and the Epistle to the Hebrews states that "The blood of sprinkling ... [speaks] better things than that of Abel" (). The blood of Jesus is interpreted as bringing mercy; but that of Abel as demanding vengeance (hence the curse and mark). Abel is invoked in the litany for the dying in the Roman Catholic Church, and his sacrifice is mentioned in the Canon of the Mass along with those of Abraham and Melchizedek. The Alexandrian Rite commemorates him with a feast day on December 28. According to the Coptic Book of Adam and Eve (at 2:1–15), and the Syriac Cave of Treasures, Abel's body, after many days of mourning, was placed in the Cave of Treasures, before which Adam and Eve, and descendants, offered their prayers. In addition, the Sethite line of the Generations of Adam swear by Abel's blood to segregate themselves from the unrighteous. In the Book of Enoch (22:7), regarded by most Christian and Jewish traditions as extra-biblical, the soul of Abel is described as having been appointed as the chief of martyrs, crying for vengeance, for the destruction of the seed of Cain. A similar view is later shown in the Testament of Abraham (A:13 / B:11), where Abel has been raised to the position as the judge of the souls. In Bereshit Rabbah (22:2), a discussion of Gen. 4:1 ff. has Rabbi Yehoshua ben Korcha mentioning that Cain was born with a twin sister, and Abel with two twin sisters. This is based on the principle that the otherwise superfluous accusative article "et" always conveys some additional teaching (Pesachim 22b). The "et"'s are parsed slightly differently in Yebamot 62a where the two "et"'s in Gen. 4:2 indicate Cain and his sister, and Abel and his (one) sister. Sethian Gnostic interpretation In the Apocryphon of John, a work belonging to Sethian Gnosticism, Abel is the offspring of Yaldaboath and Eve, who is placed over the elements of water and earth as Elohim, but was only given his name as a form of deception. Mandaean interpretation According to Mandaean beliefs and scriptures including the Qolastā, the Book of John and Genzā Rabbā, Abel is cognate with the angelic soteriological figure Hibil Ziwa, (, sometimes translated "Splendid Hibel"), who is spoken of as a son of Hayyi or of Manda d-Hayyi, and as a brother to Anush (Enosh) and to Sheetil (Seth), who is the son of Adam. Elsewhere, Anush is spoken of as the son of Sheetil, and Sheetil as the son of Hibil, where Hibil came to Adam and Eve as a young boy when they were still virgins, but was called their son. Hibil is an important lightworld being (uthra) who conquered the World of Darkness. As Yawar Hibil, he is one of multiple figures known as Yawar (), being so named by and after his father. Islamic interpretation According to Shi'a Muslim belief, Abel ("Habeel") is buried in the Nabi Habeel Mosque, located on the west mountains of Damascus, near the Zabadani Valley, overlooking the villages of the Barada river (Wadi Barada), in Syria. Shi'a are frequent visitors of this mosque for ziyarat. The mosque was built by Ottoman Wali Ahmad Pasha in 1599. In modern media Abel is portrayed by Franco Nero in the film The Bible: In the Beginning... (1966). Paul Rudd played the role of Abel in the 2009 film Year One.

https://en.wikipedia.org/wiki/Aardvark

Aardvark

The aardvark ( ; Orycteropus afer) is a medium-sized, burrowing, nocturnal mammal native to Africa. It is the only living species of the order Tubulidentata, although other prehistoric species and genera of Tubulidentata are known. Unlike most other insectivores, it has a long snout, similar to that of a pig, which is used to sniff out food. The aardvark is found over much of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. A nocturnal feeder, it subsists on ants and termites, which it will dig out of their hills using its sharp claws and powerful legs. It also digs to create burrows in which to live and rear its young. The animal is listed as "least concern" by the IUCN, although its numbers are decreasing. Aardvarks are afrotheres, a clade which also includes elephants, manatees, and hyraxes. Name and taxonomy Name The aardvark is sometimes colloquially called the "African ant bear", "anteater" (not to be confused with the South American anteater), or the "Cape anteater" after the Cape of Good Hope. The name "aardvark" is Afrikaans (), comes from earlier Afrikaans erdvark and means "earth pig" or "ground pig" (aarde: "earth/ground", vark: "pig"), because of its burrowing habits. The name Orycteropus means "burrowing foot", and the name afer refers to Africa. The name of the aardvark's order, Tubulidentata, comes from the tubule-style teeth. Taxonomy The aardvark is not closely related to the pig; rather, it is the sole extant representative of the obscure mammalian order Tubulidentata, in which it is usually considered to form one variable species of the genus Orycteropus, the sole surviving genus in the family Orycteropodidae. The aardvark is not closely related to the South American anteater, despite sharing some characteristics and a superficial resemblance. The similarities are the outcome of convergent evolution. The closest living relatives of the aardvark are the elephant shrews, tenrecidae, and golden moles. Along with sirenians, hyraxes, elephants, and their extinct relatives, these animals form the superorder Afrotheria. Studies of the brain have shown the similarities with Condylarthra, and given the clade's status as a wastebasket taxon it may mean some species traditionally classified as "condylarths" are actually stem-aardvarks. Evolutionary history Based on fossils, Bryan Patterson has concluded that early relatives of the aardvark appeared in Africa around the end of the Paleocene. The ptolemaiidans, a mysterious clade of mammals with uncertain affinities, may actually be stem-aardvarks, either as a sister clade to Tubulidentata or as a grade leading to true tubulidentates. The first unambiguous tubulidentate was probably Myorycteropus africanus from Kenyan Miocene deposits. The earliest example from the genus Orycteropus was Orycteropus mauritanicus, found in Algeria in deposits from the middle Miocene, with an equally old version found in Kenya. Fossils from the aardvark have been dated to 5 million years, and have been located throughout Europe and the Near East. The mysterious Pleistocene Plesiorycteropus from Madagascar was originally thought to be a tubulidentate that was descended from ancestors that entered the island during the Eocene. However, a number of subtle anatomical differences coupled with recent molecular evidence now lead researchers to believe that Plesiorycteropus is a relative of golden moles and tenrecs that achieved an aardvark-like appearance and ecological niche through convergent evolution. Subspecies The aardvark has seventeen poorly defined subspecies listed: Orycteropus afer afer O. a. adametzi Grote, 1921 O. a. aethiopicus Sundevall, 1843 O. a. angolensis Zukowsky & Haltenorth, 1957 O. a. erikssoni Lönnberg, 1906 O. a. faradjius Hatt, 1932 O. a. haussanus Matschie, 1900 O. a. kordofanicus Rothschild, 1927 O. a. lademanni Grote, 1911 O. a. leptodon Hirst, 1906 O. a. matschiei Grote, 1921 O. a. observandus Grote, 1921 O. a. ruvanensis Grote, 1921 O. a. senegalensis Lesson, 1840 O. a. somalicus Lydekker, 1908 O. a. wardi Lydekker, 1908 O. a. wertheri Matschie, 1898 The 1911 Encyclopædia Britannica also mentions O. a. capensis or Cape ant-bear from South Africa. Description The aardvark is vaguely pig-like in appearance. Its body is stout with a prominently arched back and is sparsely covered with coarse hairs. The limbs are of moderate length, with the rear legs being longer than the forelegs. The front feet have lost the pollex (or 'thumb'), resulting in four toes, while the rear feet have all five toes. Each toe bears a large, robust nail which is somewhat flattened and shovel-like, and appears to be intermediate between a claw and a hoof. Whereas the aardvark is considered digitigrade, it appears at times to be plantigrade. This confusion happens because when it squats it stands on its soles. A contributing characteristic to the burrow digging capabilities of aardvarks is an endosteal tissue called compacted coarse cancellous bone (CCCB). The stress and strain resistance provided by CCCB allows aardvarks to create their burrows, ultimately leading to a favorable environment for plants and a variety of animals. An aardvark's weight is typically between . An aardvark's length is usually between , and can reach lengths of when its tail (which can be up to ) is taken into account. It is tall at the shoulder, and has a girth of about . It is the largest member of the proposed clade Afroinsectiphilia. The aardvark is pale yellowish-gray in color and often stained reddish-brown by soil. The aardvark's coat is thin, and the animal's primary protection is its tough skin. Its hair is short on its head and tail; however its legs tend to have longer hair. The hair on the majority of its body is grouped in clusters of 3-4 hairs. The hair surrounding its nostrils is dense to help filter particulate matter out as it digs. Its tail is very thick at the base and gradually tapers. Head The greatly elongated head is set on a short, thick neck, and the end of the snout bears a disc, which houses the nostrils. It contains a thin but complete zygomatic arch. The head of the aardvark contains many unique and different features. One of the most distinctive characteristics of the Tubulidentata is their teeth. Instead of having a pulp cavity, each tooth has a cluster of thin, hexagonal, upright, parallel tubes of vasodentin (a modified form of dentine), with individual pulp canals, held together by cementum. The number of columns is dependent on the size of the tooth, with the largest having about 1,500. The teeth have no enamel coating and are worn away and regrow continuously. The aardvark is born with conventional incisors and canines at the front of the jaw, which fall out and are not replaced. Adult aardvarks have only cheek teeth at the back of the jaw, and have a dental formula of: These remaining teeth are peg-like and rootless and are of unique composition. The teeth consist of 14 upper and 12 lower jaw molars. The nasal area of the aardvark is another unique area, as it contains ten nasal conchae, more than any other placental mammal. The sides of the nostrils are thick with hair. The tip of the snout is highly mobile and is moved by modified mimetic muscles. The fleshy dividing tissue between its nostrils probably has sensory functions, but it is uncertain whether they are olfactory or vibratory in nature. Its nose is made up of more turbinate bones than any other mammal, with between 9 and 11, compared to dogs with 4 to 5. With a large quantity of turbinate bones, the aardvark has more space for the moist epithelium, which is the location of the olfactory bulb. The nose contains nine olfactory bulbs, more than any other mammal. Its keen sense of smell is not just from the quantity of bulbs in the nose but also in the development of the brain, as its olfactory lobe is very developed. The snout resembles an elongated pig snout. The mouth is small and tubular, typical of species that feed on ants and termites. The aardvark has a long, thin, snakelike, protruding tongue (as much as long) and elaborate structures supporting a keen sense of smell. The ears, which are very effective, are disproportionately long, about long. The eyes are small for its head, and consist only of rods. Digestive system The aardvark's stomach has a muscular pyloric area that acts as a gizzard to grind swallowed food up, thereby rendering chewing unnecessary. Its cecum is large. Both sexes emit a strong smelling secretion from an anal gland. Its salivary glands are highly developed and almost completely ring the neck; their output is what causes the tongue to maintain its tackiness. The female has two pairs of teats in the inguinal region. Genetically speaking, the aardvark is a living fossil, as its chromosomes are highly conserved, reflecting much of the early eutherian arrangement before the divergence of the major modern taxa. Habitat and range Aardvarks are found in sub-Saharan Africa, where suitable habitat (savannas, grasslands, woodlands and bushland) and food (i.e., ants and termites) is available. They spend the daylight hours in dark burrows to avoid the heat of the day. The only major habitat that they are not present in is swamp forest, as the high water table precludes digging to a sufficient depth. They also avoid terrain rocky enough to cause problems with digging. They have been documented as high as in Ethiopia. They are present throughout sub-Saharan Africa all the way to South Africa with few exceptions including the coastal areas of Namibia, Ivory Coast, and Ghana. They are not found in Madagascar. Ecology and behaviour Aardvarks live for up to 23 years in captivity. Its keen hearing warns it of predators: lions, leopards, cheetahs, African wild dogs, hyenas, and pythons. Some humans also hunt aardvarks for meat. Aardvarks can dig fast or run in zigzag fashion to elude enemies, but if all else fails, they will strike with their claws, tail and shoulders, sometimes flipping onto their backs lying motionless except to lash out with all four feet. They are capable of causing substantial damage to unprotected areas of an attacker. They will also dig to escape as they can. Sometimes, when pressed, aardvarks can dig extremely quickly. Feeding The aardvark is nocturnal and is a solitary creature that feeds almost exclusively on ants and termites (myrmecophagy); the only fruit eaten by aardvarks is the aardvark cucumber. In fact, the cucumber and the aardvark have a symbiotic relationship as they eat the subterranean fruit, then defecate the seeds near their burrows, which then grow rapidly due to the loose soil and fertile nature of the area. The time spent in the intestine of the aardvark helps the fertility of the seed, and the fruit provides needed moisture for the aardvark. They avoid eating the African driver ant and red ants. Due to their stringent diet requirements, they require a large range to survive. An aardvark emerges from its burrow in the late afternoon or shortly after sunset, and forages over a considerable home range encompassing . While foraging for food, the aardvark will keep its nose to the ground and its ears pointed forward, which indicates that both smell and hearing are involved in the search for food. They zig-zag as they forage and will usually not repeat a route for 5–8 days as they appear to allow time for the termite nests to recover before feeding on it again. During a foraging period, they will stop to dig a "V" shaped trench with their forefeet and then sniff it profusely as a means to explore their location. When a concentration of ants or termites is detected, the aardvark digs into it with its powerful front legs, keeping its long ears upright to listen for predators, and takes up an astonishing number of insects with its long, sticky tongue—as many as 50,000 in one night have been recorded. Its claws enable it to dig through the extremely hard crust of a termite or ant mound quickly. It avoids inhaling the dust by sealing the nostrils. When successful, the aardvark's long (up to ) tongue licks up the insects; the termites' biting, or the ants' stinging attacks are rendered futile by the tough skin. After an aardvark visit at a termite mound, other animals will visit to pick up all the leftovers. Termite mounds alone do not provide enough food for the aardvark, so they look for termites that are on the move. When these insects move, they can form columns long and these tend to provide easy pickings with little effort exerted by the aardvark. These columns are more common in areas of livestock or other hoofed animals. The trampled grass and dung attract termites from the Odontotermes, Microtermes, and Pseudacanthotermes genera. On a nightly basis they tend to be more active during the first portion of night (roughly the four hours between 8:00p.m. and 12:00a.m.); however, they don't seem to prefer bright or dark nights over the other. During adverse weather or if disturbed they will retreat to their burrow systems. They cover between per night; however, some studies have shown that they may traverse as far as in a night. Aardvarks shift their circadian rhythms to more diurnal activity patterns in response to a reduced food supply. This survival tactic may signify an increased risk of imminent mortality. Vocalization The aardvark is a rather quiet animal. However, it does make soft grunting sounds as it forages and loud grunts as it makes for its tunnel entrance. It makes a bleating sound if frightened. When it is threatened it will make for one of its burrows. If one is not close it will dig a new one rapidly. This new one will be short and require the aardvark to back out when the coast is clear. Movement The aardvark is known to be a good swimmer and has been witnessed successfully swimming in strong currents. It can dig a yard of tunnel in about five minutes, but otherwise moves fairly slowly. When leaving the burrow at night, they pause at the entrance for about ten minutes, sniffing and listening. After this period of watchfulness, it will bound out and within seconds it will be away. It will then pause, prick its ears, twisting its head to listen, then jump and move off to start foraging. Aside from digging out ants and termites, the aardvark also excavates burrows in which to live, which generally fall into one of three categories: burrows made while foraging, refuge and resting location, and permanent homes. Temporary sites are scattered around the home range and are used as refuges, while the main burrow is also used for breeding. Main burrows can be deep and extensive, have several entrances and can be as long as . These burrows can be large enough for a person to enter. The aardvark changes the layout of its home burrow regularly, and periodically moves on and makes a new one. The old burrows are an important part of the African wildlife scene. As they are vacated, then they are inhabited by smaller animals like the African wild dog, ant-eating chat, Nycteris thebaica and warthogs. Other animals that use them are hares, mongooses, hyenas, owls, pythons, and lizards. Without these refuges many animals would die during wildfire season. Only mothers and young share burrows; however, the aardvark is known to live in small family groups or as a solitary creature. If attacked in the tunnel, it will escape by digging out of the tunnel thereby placing the fresh fill between it and its predator, or if it decides to fight it will roll onto its back, and attack with its claws. The aardvark has been known to sleep in a recently excavated ant nest, which also serves as protection from its predators. Reproduction Aardvarks pair only during the breeding season; after a gestation period of seven months, one cub weighing around is born during May–July. When born, the young has flaccid ears and many wrinkles. When nursing, it will nurse off each teat in succession. After two weeks, the folds of skin disappear and after three, the ears can be held upright. After 5–6 weeks, body hair starts growing. It is able to leave the burrow to accompany its mother after only two weeks and eats termites at 9 weeks, and is weaned between three months and 16 weeks. At six months of age, it is able to dig its own burrows, but it will often remain with the mother until the next mating season, and is sexually mature from approximately two years of age. Conservation Aardvarks were thought to have declining numbers, however, this is possibly because they are not readily seen. There are no definitive counts because of their nocturnal and secretive habits; however, their numbers seem to be stable overall. They are not considered common anywhere in Africa, but due to their large range, they maintain sufficient numbers. There may be a slight decrease in numbers in eastern, northern, and western Africa. Southern African numbers are not decreasing. It has received an official designation from the IUCN as least concern. However, they are a species in a precarious situation, as they are so dependent on such specific food; therefore if a problem arises with the abundance of termites, the species as a whole would be affected drastically. Recent research suggests that aardvarks may be particularly vulnerable to alterations in temperature caused by climate change. Droughts negatively impact the availability of termites and ants, which comprise the bulk of an aardvark's diet. Nocturnal species faced with resource scarcity may increase their diurnal activity to spare the energy costs of staying warm at night, but this comes at the cost of withstanding high temperatures during the day. A study on aardvarks in the Kalahari Desert saw that five out of six aardvarks being studied perished following a drought. Aardvarks that survive droughts can take long periods of time to regain health and optimal thermoregulatory physiology, reducing the reproductive potential of the species. Aardvarks handle captivity well. The first zoo to have one was London Zoo in 1869, which had an animal from South Africa. Mythology and popular culture In African folklore, the aardvark is much admired because of its diligent quest for food and its fearless response to soldier ants. Hausa magicians make a charm from the heart, skin, forehead, and nails of the aardvark, which they then proceed to pound together with the root of a certain tree. Wrapped in a piece of skin and worn on the chest, the charm is said to give the owner the ability to pass through walls or roofs at night. The charm is said to be used by burglars and those seeking to visit young girls without their parents' permission. Also, some tribes, such as the Margbetu, Ayanda, and Logo, will use aardvark teeth to make bracelets, which are regarded as good luck charms. The meat, which has a resemblance to pork, is eaten in certain cultures. The ancient Egyptian god Set is usually depicted with the head of an unidentified animal, whose similarity to an aardvark has been noted in scholarship. The titular character and his families from Arthur, an animated television series for children based on a book series and produced by WGBH, shown in more than 180 countries, is an aardvark. In the first book of the series, Arthur's Nose (1976), he has a long, aardvark-like nose, but in later books, his face becomes more rounded. Otis the Aardvark was a puppet character used on Children's BBC programming. An aardvark features as the antagonist in the cartoon The Ant and the Aardvark as well as in the Canadian animated series The Raccoons. The supersonic fighter-bomber F-111/FB-111 was nicknamed the Aardvark because of its long nose resembling the animal. It also had similarities with its nocturnal missions flown at a very low level employing ordnance that could penetrate deep into the ground. In the US Navy, the squadron VF-114 was nicknamed the Aardvarks, flying F-4s and then F-14s. The squadron mascot was adapted from the animal in the comic strip B.C., which the F-4 was said to resemble. Cerebus the Aardvark is a 300-issue comic book series by Dave Sim.

Aardwolf

The aardwolf (Proteles cristata) is an insectivorous species of hyena, native to East and Southern Africa. Its name means "earth-wolf" in Afrikaans and Dutch. It is also called the maanhaar-jackal (Afrikaans for "mane-jackal"), termite-eating hyena and civet hyena, based on its habit of secreting substances from its anal gland, a characteristic shared with the African civet. Unlike many of its relatives in the order Carnivora, the aardwolf does not hunt large animals. It eats insects and their larvae, mainly termites; one aardwolf can lap up as many as 300,000 termites during a single night using its long, sticky tongue. The aardwolf's tongue has adapted to be tough enough to withstand the strong bite of termites. The aardwolf lives in the shrublands of eastern and southern Africa – open lands covered with stunted trees and shrubs. It is nocturnal, resting in burrows during the day and emerging at night to seek food. Taxonomy The aardwolf is generally classified with the hyena family Hyaenidae, though it was formerly placed in its own family Protelidae. Early on, scientists felt that it was merely mimicking the striped hyena, which subsequently led to the creation of Protelidae. Recent studies have suggested that the aardwolf probably diverged from other hyaenids early on; how early is still unclear, as the fossil record and genetic studies disagree by 10 million years. The aardwolf is the only surviving species in the subfamily Protelinae. There is disagreement as to whether the species is monotypic, or can be divided into subspecies P. c. cristatus of Southern Africa and P. c. septentrionalis of East Africa. A 2006 molecular analysis indicates that it is phylogenetically the most basal of the four extant hyaenidae species. Etymology The generic name proteles comes from two words both of Greek origin, protos and teleos which combined means "complete in front" based on the fact that they have five toes on their front feet and four on the rear. The specific name, cristatus, comes from Latin and means "provided with a comb", relating to their mane. Description The aardwolf resembles a very thin striped hyena, but with a more slender muzzle, black vertical stripes on a coat of yellowish fur, and a long, distinct mane down the midline of the neck and back. It also has one or two diagonal stripes down the fore- and hind-quarters, along with several stripes on its legs. The mane is raised during confrontations to make the aardwolf appear larger. It is missing the throat spot that others in the family have. Its lower leg (from the knee down) is all black, and its tail is bushy with a black tip. The aardwolf is about long, excluding its bushy tail, which is about long, and stands about tall at the shoulders. An adult aardwolf weighs approximately , sometimes reaching . The aardwolves in the south of the continent tend to be smaller (about ) than the eastern version (around ). This makes the aardwolf, the smallest extant member of the Hyaenidae family. The front feet have five toes each, unlike the four-toed hyena. The teeth and skull are similar in shape to those of other hyenas, though much smaller, and its cheek teeth are specialised for eating insects. It does still have canines, but, unlike other hyenas, these teeth are used primarily for fighting and defense. Its ears, which are large, are very similar to those of the striped hyena. As an aardwolf ages, it will normally lose some of its teeth, though this has little impact on its feeding habits due to the softness of the insects that it eats. Distribution and habitat Aardwolves live in open, dry plains and bushland, avoiding mountainous areas. Due to their specific food requirements, they are only found in regions where termites of the family Hodotermitidae occur. Termites of this family depend on dead and withered grass and are most populous in heavily grazed grasslands and savannahs, including farmland. For most of the year, aardwolves spend time in shared territories consisting of up to a dozen dens, which are occupied for six weeks at a time. There are two distinct populations: one in Southern Africa, and another in East and Northeast Africa. The species does not occur in the intermediary miombo forests. An adult pair, along with their most-recent offspring, occupies a territory of . Behavior and ecology Aardwolves are shy and nocturnal, sleeping in burrows by day. They will, on occasion during the winter, become diurnal feeders. This happens during the coldest periods as they then stay in at night to conserve heat. They have often been mistaken for solitary animals. In fact, they live as monogamous pairs with their young. If their territory is infringed upon, they will chase the intruder up to or to the border. If the intruder is caught, which rarely happens, a fight will occur, which is accompanied by soft clucking, hoarse barking, and a type of roar. The majority of incursions occur during mating season, when they can occur once or twice per week. When food is scarce, the stringent territorial system may be abandoned and as many as three pairs may occupy a single territory. The territory is marked by both sexes, as they both have developed anal glands from which they extrude a black substance that is smeared on rocks or grass stalks in -long streaks. Aardwolves also have scent glands on the forefoot and penile pad. They often mark near termite mounds within their territory every 20 minutes or so. If they are patrolling their territorial boundaries, the marking frequency increases drastically, to once every . At this rate, an individual may mark 60 marks per hour, and upwards of 200 per night. An aardwolf pair may have up to 10 dens, and numerous feces middens, within their territory. When they deposit excreta at their middens, they dig a small hole and cover it with sand. Their dens are usually abandoned aardvark, springhare, or porcupine dens, or on occasion they are crevices in rocks. They will also dig their own dens, or enlarge dens started by springhares. They typically will only use one or two dens at a time, rotating through all of their dens every six months. During the summer, they may rest outside their den during the night and sleep underground during the heat of the day. Aardwolves are not fast runners nor are they particularly adept at fighting off predators. Therefore, when threatened, the aardwolf may attempt to mislead its foe by doubling back on its tracks. If confronted, it may raise its mane in an attempt to appear more menacing. It also emits a foul-smelling liquid from its anal glands. Feeding The aardwolf feeds primarily on termites and more specifically on Trinervitermes. This genus of termites has different species throughout the aardwolf's range. In East Africa, they eat Trinervitermes bettonianus, in central Africa, they eat Trinervitermes rhodesiensis, and in southern Africa, they eat T. trinervoides. Their technique consists of licking them off the ground as opposed to the aardvark, which digs into the mound. They locate their food by sound and also from the scent secreted by the soldier termites. An aardwolf may consume up to 250,000 termites per night using its long, sticky tongue. They do not destroy the termite mound or consume the entire colony, thus ensuring that the termites can rebuild and provide a continuous supply of food. They often memorize the location of such nests and return to them every few months. During certain seasonal events, such as the onset of the rainy season and the cold of midwinter, the primary termites become scarce, so the need for other foods becomes pronounced. During these times, the southern aardwolf will seek out Hodotermes mossambicus, a type of harvester termite active in the afternoon, which explains some of their diurnal behavior in the winter. The eastern aardwolf, during the rainy season, subsists on termites from the genera Odontotermes and Macrotermes. They are also known to feed on other insects, larvae, eggs, and, some sources say, occasionally small mammals and birds, but these constitute a very small percentage of their total diet. Unlike other hyenas, aardwolves do not scavenge or kill larger animals. Contrary to popular myths, aardwolves do not eat carrion, and if they are seen eating while hunched over a dead carcass, they are actually eating larvae and beetles. Also, contrary to some sources, they do not like meat, unless it is finely ground or cooked for them. The adult aardwolf was formerly assumed to forage in small groups, but more recent research has shown that they are primarily solitary foragers, necessary because of the scarcity of their insect prey. Their primary source, Trinervitermes, forages in small but dense patches of . While foraging, the aardwolf can cover about per hour, which translates to per summer night and per winter night. Breeding The breeding season varies depending on location, but normally takes place during autumn or spring. In South Africa, breeding occurs in early July. During the breeding season, unpaired male aardwolves search their own territory, as well as others, for a female to mate with. Dominant males also mate opportunistically with the females of less dominant neighboring aardwolves, which can result in conflict between rival males. Dominant males even go a step further and as the breeding season approaches, they make increasingly greater and greater incursions onto weaker males' territories. As the female comes into oestrus, they add pasting to their tricks inside of the other territories, sometimes doing so more in rivals' territories than their own. Females will also, when given the opportunity, mate with the dominant male, which increases the chances of the dominant male guarding "his" cubs with her. Copulation lasts between 1 and 4.5 hours. Gestation lasts between 89 and 92 days, producing two to five cubs (most often two or three) during the rainy season (November–December), when termites are more active. They are born with their eyes open, but initially are helpless, and weigh around . The first six to eight weeks are spent in the den with their parents. The male may spend up to six hours a night watching over the cubs while the mother is out looking for food. After three months, they begin supervised foraging, and by four months are normally independent, though they often share a den with their mother until the next breeding season. By the time the next set of cubs is born, the older cubs have moved on. Aardwolves generally achieve sexual maturity at one and a half to two years of age. Conservation The aardwolf has not seen decreasing numbers and is relatively widespread throughout eastern Africa. They are not common throughout their range, as they maintain a density of no more than 1 per square kilometer, if food is abundant. Because of these factors, the IUCN has rated the aardwolf as least concern. In some areas, they are persecuted because of the mistaken belief that they prey on livestock; however, they are actually beneficial to the farmers because they eat termites that are detrimental. In other areas, the farmers have recognized this, but they are still killed, on occasion, for their fur. Dogs and insecticides are also common killers of the aardwolf. In captivity Frankfurt Zoo in Germany was home to the oldest recorded aardwolf in captivity at 18 years and 11 months.

Adobe

Adobe ( ; ) is a building material made from earth and organic materials. is Spanish for mudbrick. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. Adobe architecture has been dated to before 5,100 B.C. Description Adobe bricks are rectangular prisms small enough that they can quickly air dry individually without cracking. They can be subsequently assembled, with the application of adobe mud to bond the individual bricks into a structure. There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured weighing about ; in other contexts the size is weighing about . The maximum sizes can reach up to ; above this weight it becomes difficult to move the pieces, and it is preferred to ram the mud in situ, resulting in a different typology known as rammed earth. Strength In dry climates, adobe structures are extremely durable, and account for some of the oldest existing buildings in the world. Adobe buildings offer significant advantages due to their greater thermal mass, but they are known to be particularly susceptible to earthquake damage if they are not reinforced. Cases where adobe structures were widely damaged during earthquakes include the 1976 Guatemala earthquake, the 2003 Bam earthquake, and the 2010 Chile earthquake. Distribution Buildings made of sun-dried earth are common throughout the world (Middle East, Western Asia, North Africa, West Africa, South America, southwestern North America, Southwestern and Eastern Europe.) Adobe had been in use by indigenous peoples of the Americas in the Southwestern United States, Mesoamerica, and the Andes for several thousand years. Puebloan peoples built their adobe structures with handsful or basketsful of adobe, until the Spanish introduced them to making bricks. Adobe bricks were used in Spain from the Late Bronze and Iron Ages (eighth century BCE onwards). Its wide use can be attributed to its simplicity of design and manufacture, and economics. Etymology The word adobe has existed for around 4000 years with relatively little change in either pronunciation or meaning. The word can be traced from the Middle Egyptian (c. 2000 BC) word ḏbt "mud brick" (with vowels unwritten). Middle Egyptian evolved into Late Egyptian and finally to Coptic (c. 600 BC), where it appeared as ⲧⲱⲃⲉ tōbə. This was adopted into Arabic as aṭ-ṭawbu or aṭ-ṭūbu, with the definite article al- attached to the root tuba. This was assimilated into the Old Spanish language as adobe , probably via Mozarabic. English borrowed the word from Spanish in the early 18th century, still referring to mudbrick construction. In more modern English usage, the term adobe has come to include a style of architecture popular in the desert climates of North America, especially in New Mexico, regardless of the construction method. Composition An adobe brick is a composite material made of earth mixed with water and an organic material such as straw or dung. The soil composition typically contains sand, silt and clay. Straw is useful in binding the brick together and allowing the brick to dry evenly, thereby preventing cracking due to uneven shrinkage rates through the brick. Dung offers the same advantage. The most desirable soil texture for producing the mud of adobe is 15% clay, 10–30% silt, and 55–75% fine sand. Another source quotes 15–25% clay and the remainder sand and coarser particles up to cobbles , with no deleterious effect. Modern adobe is stabilized with either emulsified asphalt or Portland cement up to 10% by weight. No more than half the clay content should be expansive clays, with the remainder non-expansive illite or kaolinite. Too much expansive clay results in uneven drying through the brick, resulting in cracking, while too much kaolinite will make a weak brick. Typically the soils of the Southwest United States, where such construction has been widely used, are an adequate composition. Material properties Adobe walls are load bearing, i.e. they carry their own weight into the foundation rather than by another structure, hence the adobe must have sufficient compressive strength. In the United States, most building codes call for a minimum compressive strength of 300 lbf/in2 (2.07 newton/mm2) for the adobe block. Adobe construction should be designed so as to avoid lateral structural loads that would cause bending loads. The building codes require the building sustain a 1 g lateral acceleration earthquake load. Such an acceleration will cause lateral loads on the walls, resulting in shear and bending and inducing tensile stresses. To withstand such loads, the codes typically call for a tensile modulus of rupture strength of at least 50 lbf/in2 (0.345 newton/mm2) for the finished block. In addition to being an inexpensive material with a small resource cost, adobe can serve as a significant heat reservoir due to the thermal properties inherent in the massive walls typical in adobe construction. In climates typified by hot days and cool nights, the high thermal mass of adobe mediates the high and low temperatures of the day, moderating the temperature of the living space. The massive walls require a large and relatively long input of heat from the sun (radiation) and from the surrounding air (convection) before they warm through to the interior. After the sun sets and the temperature drops, the warm wall will continue to transfer heat to the interior for several hours due to the time-lag effect. Thus, a well-planned adobe wall of the appropriate thickness is very effective at controlling inside temperature through the wide daily fluctuations typical of desert climates, a factor which has contributed to its longevity as a building material. Thermodynamic material properties have significant variation in the literature. Some experiments suggest that the standard consideration of conductivity is not adequate for this material, as its main thermodynamic property is inertia, and conclude that experimental tests should be performed over a longer period of time than usual - preferably with changing thermal jumps. There is an effective R-value for a north facing 10-in wall of R0=10 hr ft2 °F/Btu, which corresponds to thermal conductivity k=10 in x 1 ft/12 in /R0=0.33 Btu/(hr ft °F) or 0.57 W/(m K) in agreement with the thermal conductivity reported from another source. To determine the total R-value of a wall, scale R0 by the thickness of the wall in inches. The thermal resistance of adobe is also stated as an R-value for a 10-inch wall R0=4.1 hr ft2 °F/Btu. Another source provides the following properties: conductivity=0.30 Btu/(hr ft °F) or 0.52 W/(m K); specific heat capacity=0.24 Btu/(lb °F) or 1 kJ/(kg K) and density=106 lb/ft3 or 1700 kg/m3, giving heat capacity=25.4 Btu/(ft3 °F) or 1700 kJ/(m3 K). Using the average value of the thermal conductivity as k = 32 Btu/(hr ft °F) or 0.55 W/(m K), the thermal diffusivity is calculated to be 0.013 ft2/h or 3.3x10−7 m2/s. Uses Poured and puddled adobe walls Poured and puddled adobe (puddled clay, piled earth), today called cob, is made by placing soft adobe in layers, rather than by making individual dried bricks or using a form. "Puddle" is a general term for a clay or clay and sand-based material worked into a dense, plastic state. These are the oldest methods of building with adobe in the Americas until holes in the ground were used as forms, and later wooden forms used to make individual bricks were introduced by the Spanish. Adobe bricks Bricks made from adobe are usually made by pressing the mud mixture into an open timber frame. In North America, the brick is typically about in size. The mixture is molded into the frame, which is removed after initial setting. After drying for a few hours, the bricks are turned on edge to finish drying. Slow drying in shade reduces cracking. The same mixture, without straw, is used to make mortar and often plaster on interior and exterior walls. Some cultures used lime-based cement for the plaster to protect against rain damage. Depending on the form into which the mixture is pressed, adobe can encompass nearly any shape or size, provided drying is even and the mixture includes reinforcement for larger bricks. Reinforcement can include manure, straw, cement, rebar, or wooden posts. Straw, cement, or manure added to a standard adobe mixture can produce a stronger, more crack-resistant brick. A test is done on the soil content first. To do so, a sample of the soil is mixed into a clear container with some water, creating an almost completely saturated liquid. The container is shaken vigorously for one minute. It is then allowed to settle for a day until the soil has settled into layers. Heavier particles settle out first, sand above, silt above that, and very fine clay and organic matter will stay in suspension for days. After the water has cleared, percentages of the various particles can be determined. Fifty to 60 percent sand and 35 to 40 percent clay will yield strong bricks. The Cooperative State Research, Education, and Extension Service at New Mexico State University recommends a mix of not more than clay, not less than sand, and never more than silt. During the Great Depression, designer and builder Hugh W. Comstock used cheaper materials and made a specialized adobe brick called "Bitudobe." His first adobe house was built in 1936. In 1948, he published the book Post-Adobe; Simplified Adobe Construction Combining A Rugged Timber Frame And Modern Stabilized Adobe, which described his method of construction, including how to make "Bitudobe." In 1938, he served as an adviser to the architects Franklin & Kump Associates, who built the Carmel High School, which used his Post-adobe system. Adobe wall construction The ground supporting an adobe structure should be compressed, as the weight of adobe wall is significant and foundation settling may cause cracking of the wall. Footing depth is to be below the ground frost level. The footing and stem wall are commonly 24 and 14 inches thick, respectively. Modern construction codes call for the use of reinforcing steel in the footing and stem wall. Adobe bricks are laid by course. Adobe walls usually never rise above two stories as they are load bearing and adobe has low structural strength. When creating window and door openings, a lintel is placed on top of the opening to support the bricks above. Atop the last courses of brick, bond beams made of heavy wood beams or modern reinforced concrete are laid to provide a horizontal bearing plate for the roof beams and to redistribute lateral earthquake loads to shear walls more able to carry the forces. To protect the interior and exterior adobe walls, finishes such as mud plaster, whitewash or stucco can be applied. These protect the adobe wall from water damage, but need to be reapplied periodically. Alternatively, the walls can be finished with other nontraditional plasters that provide longer protection. Bricks made with stabilized adobe generally do not need protection of plasters. Adobe roof The traditional adobe roof has been constructed using a mixture of soil/clay, water, sand and organic materials. The mixture was then formed and pressed into wood forms, producing rows of dried earth bricks that would then be laid across a support structure of wood and plastered into place with more adobe. Depending on the materials available, a roof may be assembled using wood or metal beams to create a framework to begin layering adobe bricks. Depending on the thickness of the adobe bricks, the framework has been preformed using a steel framing and a layering of a metal fencing or wiring over the framework to allow an even load as masses of adobe are spread across the metal fencing like cob and allowed to air dry accordingly. This method was demonstrated with an adobe blend heavily impregnated with cement to allow even drying and prevent cracking. The more traditional flat adobe roofs are functional only in dry climates that are not exposed to snow loads. The heaviest wooden beams, called vigas, lie atop the wall. Across the vigas lie smaller members called latillas and upon those brush is then laid. Finally, the adobe layer is applied. To construct a flat adobe roof, beams of wood were laid to span the building, the ends of which were attached to the tops of the walls. Once the vigas, latillas and brush are laid, adobe bricks are placed. An adobe roof is often laid with bricks slightly larger in width to ensure a greater expanse is covered when placing the bricks onto the roof. Following each individual brick should be a layer of adobe mortar, recommended to be at least thick to make certain there is ample strength between the brick's edges and also to provide a relative moisture barrier during rain. Roof design evolved around 1850 in the American Southwest. Three inches of adobe mud was applied on top of the latillas, then 18 inches of dry adobe dirt applied to the roof. The dirt was contoured into a low slope to a downspout aka a 'canal'. When moisture was applied to the roof the clay particles expanded to create a waterproof membrane. Once a year it was necessary to pull the weeds from the roof and re-slope the dirt as needed. Depending on the materials, adobe roofs can be inherently fire-proof. The construction of a chimney can greatly influence the construction of the roof supports, creating an extra need for care in choosing the materials. The builders can make an adobe chimney by stacking simple adobe bricks in a similar fashion as the surrounding walls. In 1927, the Uniform Building Code (UBC) was adopted in the United States. Local ordinances, referencing the UBC added requirements to building with adobe. These included: restriction of building height of adobe structures to 1-story, requirements for adobe mix (compressive and shear strength) and new requirements which stated that every building shall be designed to withstand seismic activity, specifically lateral forces. By the 1980s however, seismic related changes in the California Building Code effectively ended solid wall adobe construction in California; however Post-and-Beam adobe and veneers are still being used. Adobe around the world The largest structure ever made from adobe is the Arg-é Bam built by the Achaemenid Empire. Other large adobe structures are the Huaca del Sol in Peru, with 100 million signed bricks and the ciudellas of Chan Chan and Tambo Colorado, both in Peru.

Adventure

An adventure is an exciting experience or undertaking that is typically bold, sometimes risky. Adventures may be activities with danger such as traveling, exploring, skydiving, mountain climbing, scuba diving, river rafting, or other extreme sports. Adventures are often undertaken to create psychological arousal or in order to achieve a greater goal, such as the pursuit of knowledge that can only be obtained by such activities. Motivation Adventurous experiences create psychological arousal, which can be interpreted as negative (e.g. fear) or positive (e.g. flow). For some people, adventure becomes a major pursuit in and of itself. According to adventurer André Malraux, in his Man's Fate (1933), "If a man is not ready to risk his life, where is his dignity?". Similarly, Helen Keller stated that "Life is either a daring adventure or nothing." Outdoor adventurous activities are typically undertaken for the purposes of recreation or excitement: examples are adventure racing and adventure tourism. Adventurous activities can also lead to gains in knowledge, such as those undertaken by explorers and pioneers – the British adventurer Jason Lewis, for example, uses adventures to draw global sustainability lessons from living within finite environmental constraints on expeditions to share with schoolchildren. Adventure education intentionally uses challenging experiences for learning. Author Jon Levy suggests that an experience should meet several criteria to be considered an adventure: Be remarkable—that is, worth talking about Involve adversity or perceived risk Bring about personal growth. Mythology and fiction Some of the oldest and most widespread stories in the world are stories of adventure, such as Homer's Odyssey. The knight errant was the form the "adventure seeker" character took in the Late Middle Ages. Adventure fiction exhibits these "protagonist on adventurous journey" characteristics, as do many popular feature films, such as Star Wars and Raiders of the Lost Ark. Outdoors Adventure books may have the theme of the hero or main character going to face the wilderness or Mother Nature. Examples include books such as Hatchet or My Side of the Mountain. These books are less about "questing", such as in mythology or other adventure novels, but more about surviving on their own, living off the land, gaining new experiences, and becoming closer to the natural world. Questing Many adventures are based on the idea of a quest: the hero goes off in pursuit of a reward, whether it be a skill, prize, treasure, or perhaps the safety of a person. On the way, the hero must overcome various obstacles to obtain their reward. Video games In video game culture, an adventure game is a video game in which the player assumes the role of a protagonist in an interactive story driven by exploration and puzzle solving. The genre's focus on story allows it to draw heavily from other narrative-based media, literature and film, encompassing a wide variety of literary genres. Many adventure games (text and graphic) are designed for a single player, since this emphasis on story and character makes multi-player design difficult. Nonfiction works From ancient times, travelers and explorers have written about their adventures. Journals which became best-sellers in their day were written, such as Marco Polo's journal The Travels of Marco Polo or Mark Twain's Roughing It. Others were personal journals, only later published, such as the journals of Meriwether Lewis and William Clark or Captain James Cook's journals. There are also books written by those not directly a part of the adventure in question, such as The Right Stuff by Tom Wolfe or books written by those participating in the adventure but in a format other than that of a journal, such as Conquistadors of the Useless by Lionel Terray. Documentaries often use the theme of adventure as well. Adventure sports There are many sports classified as adventure sports, due to their inherent danger and excitement. Some of these include mountain climbing, skydiving, or other extreme sports.

Asia

Asia (, ) is the largest continent in the world by both land area and population. It is part of Eurasia. It covers an area of more than 44 million square kilometers, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population, having more people than all other continents combined. Asia shares the landmass of Afro-Eurasia with Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, and ethnic differences, some of which vary on a spectrum rather than with a sharp dividing line. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish Straits, the Ural Mountains and Ural River, and to the south of the Caucasus Mountains and the Caspian and Black seas, separating it from Europe. China and India alternated in being the largest economies in the world from 1 to 1,800 CE. China was a major economic power and attracted many to the east, and for many the legendary wealth and prosperity of the ancient culture of India personified Asia, attracting European commerce, exploration and colonialism. The accidental discovery of a trans-Atlantic route from Europe to America by Columbus while in search for a route to India demonstrates this deep fascination. The Silk Road became the main east–west trading route in the Asian hinterlands while the Straits of Malacca stood as a major sea route. Asia has exhibited economic dynamism (particularly East Asia) as well as robust population growth during the 20th century, but overall population growth has since fallen. Asia was the birthplace of most of the world's mainstream religions including Hinduism, Zoroastrianism, Judaism, Jainism, Buddhism, Confucianism, Taoism, Christianity, Islam, Sikhism, as well as many other religions. Given its size and diversity, the concept of Asia—a name dating back to classical antiquity—may actually have more to do with human geography than physical geography. Asia varies greatly across and within its regions with regard to ethnic groups, cultures, environments, economics, historical ties and government systems. It also has a mix of many different climates ranging from the equatorial south via the hot desert in the Middle East, temperate areas in the east and the continental centre to vast subarctic and polar areas in Siberia. Definition and boundaries Asia–Africa boundary The boundary between Asia and Africa is the Red Sea, the Gulf of Suez, and the Suez Canal. This makes Egypt a transcontinental country, with the Sinai peninsula in Asia and the remainder of the country in Africa. Asia–Europe boundary The threefold division of the Old World into Europe, Asia and Africa has been in use since the 6th century BCE, due to Greek geographers such as Anaximander and Hecataeus. Anaximander placed the boundary between Asia and Europe along the Phasis River (the modern Rioni river) in Georgia of Caucasus (from its mouth by Poti on the Black Sea coast, through the Surami Pass and along the Kura River to the Caspian Sea), a convention still followed by Herodotus in the 5th century BCE. During the Hellenistic period, this convention was revised, and the boundary between Europe and Asia was now considered to be the Tanais (the modern Don River). This is the convention used by Roman era authors such as Posidonius, Strabo and Ptolemy. The border between Asia and Europe was historically defined by European academics. The Don River became unsatisfactory to northern Europeans when Peter the Great, king of the Tsardom of Russia, defeating rival claims of Sweden and the Ottoman Empire to the eastern lands, and armed resistance by the tribes of Siberia, synthesized a new Russian Empire extending to the Ural Mountains and beyond, founded in 1721. In Sweden, five years after Peter's death, in 1730 Philip Johan von Strahlenberg published a new atlas proposing the Ural Mountains as the border of Asia. Tatishchev announced that he had proposed the idea to von Strahlenberg. The latter had suggested the Emba River as the lower boundary. Over the next century various proposals were made until the Ural River prevailed in the mid-19th century. The border had been moved perforce from the Black Sea to the Caspian Sea into which the Ural River projects. The border between the Black Sea and the Caspian is usually placed along the crest of the Caucasus Mountains, although it is sometimes placed further north. Asia–Oceania boundary The border between Asia and the region of Oceania is usually placed somewhere in the Malay Archipelago. The Maluku Islands in Indonesia are often considered to lie on the border of southeast Asia, with New Guinea, to the east of the islands, being wholly part of Oceania. The terms Southeast Asia and Oceania, devised in the 19th century, have had several vastly different geographic meanings since their inception. The chief factor in determining which islands of the Malay Archipelago are Asian has been the location of the colonial possessions of the various empires there (not all European). Lewis and Wigen assert, "The narrowing of 'Southeast Asia' to its present boundaries was thus a gradual process." Asia–North America boundary The Bering Strait and Bering Sea separate the landmasses of Asia and North America, as well as forming the international boundary between Russia and the United States. This national and continental boundary separates the Diomede Islands in the Bering Strait, with Big Diomede in Russia and Little Diomede in the United States. The Aleutian Islands are an island chain extending westward from the Alaskan Peninsula toward Russia's Komandorski Islands and Kamchatka Peninsula. Most of them are always associated with North America, except for the westernmost Near Islands group, which is on Asia's continental shelf beyond the North Aleutians Basin and on rare occasions could be associated with Asia, which could then allow the U.S. state of Alaska as well as the United States itself to be considered a transcontinental state. The Aleutian Islands are sometimes associated with Oceania, owing to their status as remote Pacific islands, and their proximity to the Pacific Plate. This is extremely rare however, due to their non-tropical biogeography, as well as their inhabitants, who have historically been related to Indigenous Americans. St. Lawrence Island in the northern Bering Sea belongs to Alaska and may be associated with either continent but is almost always considered part of North America, as with the Rat Islands in the Aleutian chain. At their nearest points, Alaska and Russia are separated by only . Ongoing definition Geographical Asia is a cultural artifact of European conceptions of the world, beginning with the Ancient Greeks, being imposed onto other cultures, an imprecise concept causing endemic contention about what it means. Asia does not exactly correspond to the cultural borders of its various types of constituents. From the time of Herodotus a minority of geographers have rejected the three-continent system (Europe, Africa, Asia) on the grounds that there is no substantial physical separation between them. For example, Sir Barry Cunliffe, the emeritus professor of European archeology at Oxford, argues that Europe has been geographically and culturally merely "the western excrescence of the continent of Asia". Geographically, Asia is the major eastern constituent of the continent of Eurasia with Europe being a northwestern peninsula of the landmass. Asia, Europe and Africa make up a single continuous landmass—Afro-Eurasia (except for the Suez Canal)—and share a common continental shelf. Almost all of Europe and a major part of Asia sit atop the Eurasian Plate, adjoined on the south by the Arabian and Indian Plate and with the easternmost part of Siberia (east of the Chersky Range) on the North American Plate. Etymology The idea of a place called "Asia" was originally a concept of Greek civilization, though this did not correspond to the entire continent currently known by that name (which was unknown to Greece at the time). The English word comes from Latin literature, where it has the same form, "Asia". Whether "Asia" in other languages comes from Latin of the Roman Empire is much less certain, and the ultimate source of the Latin word is uncertain, though several theories have been published. One of the first classical writers to use Asia as a name of the whole continent was Pliny. This metonymical change in meaning is common and can be observed in some other geographical names, such as Scandinavia (from Scania). Bronze Age Before Greek poetry, the Aegean Sea area was in a Greek Dark Age, at the beginning of which syllabic writing was lost and alphabetic writing had not begun. Prior to then in the Bronze Age the records of the Assyrian Empire, the Hittite Empire and the various Mycenaean states of Greece mention a region undoubtedly Asia, certainly in Anatolia, including if not identical to Lydia. These records are administrative and do not include poetry. The Mycenaean states were destroyed about 1200 BCE by unknown agents, though one school of thought assigns the Dorian invasion to this time. The burning of the palaces caused the clay tablets holding the Mycenaean administrative records to be preserved by baking. These tablets were written in a Greek syllabic script called Linear B. This script was deciphered by a number of interested parties, most notably by a young World War II cryptographer, Michael Ventris, subsequently assisted by the scholar, John Chadwick. A major cache discovered by Carl Blegen at the site of ancient Pylos included hundreds of male and female names formed by different methods. Some of these are of women held in servitude (as study of the society implied by the content reveals). They were used in trades, such as cloth-making, and usually came with children. The epithet lawiaiai, "captives", associated with some of them identifies their origin. Some are ethnic names. One in particular, aswiai, identifies "women of Asia". Perhaps they were captured in Asia, but some others, Milatiai, appear to have been of Miletus, a Greek colony, which would not have been raided for slaves by Greeks. Chadwick suggests that the names record the locations where these foreign women were purchased. The name is also in the singular, Aswia, which refers both to the name of a country and to a female from there. There is a masculine form, . This Aswia appears to have been a remnant of a region known to the Hittites as Assuwa, centered on Lydia. This name, Assuwa, has been suggested as the origin for the name of the continent "Asia". The Assuwa league was a confederation of states in western Anatolia, defeated by the Hittites under Tudhaliya I around 1400 BCE. Classical antiquity Latin Asia and Greek Ἀσία appear to be the same word. Roman authors translated Ἀσία as Asia. The Romans named a province Asia, located in western Anatolia (in modern-day Turkey). There was an Asia Minor and an Asia Major located in modern-day Iraq. As the earliest evidence of the name is Greek, it is likely circumstantially that Asia came from Ἀσία, but ancient transitions, due to the lack of literary contexts, are difficult to catch in the act. The most likely vehicles were the ancient geographers and historians, such as Herodotus, who were all Greek. Ancient Greek certainly evidences early and rich uses of the name. The first continental use of Asia is attributed to Herodotus (about 440 BCE), not because he innovated it, but because his Histories are the earliest surviving prose to describe it in any detail. He defines it carefully, mentioning the previous geographers whom he had read, but whose works are now missing. By it he means Anatolia and the Persian Empire, in contrast to Greece and Egypt. Herodotus comments that he is puzzled as to why three women's names were "given to a tract which is in reality one" (Europa, Asia, and Libya, referring to Africa), stating that most Greeks assumed that Asia was named after the wife of Prometheus (i.e. Hesione), but that the Lydians say it was named after Asies, son of Cotys, who passed the name on to a tribe at Sardis. In Greek mythology, "Asia" (Ἀσία) or "Asie" (Ἀσίη) was the name of a "Nymph or Titan goddess of Lydia". In ancient Greek religion, places were under the care of female divinities, parallel to guardian angels. The poets detailed their doings and generations in allegoric language salted with entertaining stories, which subsequently playwrights transformed into classical Greek drama and became "Greek mythology". For example, Hesiod mentions the daughters of Tethys and Ocean, among whom are a "holy company", "who with the Lord Apollo and the Rivers have youths in their keeping". Many of these are geographic: Doris, Rhodea, Europa, Asia. Hesiod explains: The Iliad (attributed by the ancient Greeks to Homer) mentions two Phrygians (the tribe that replaced the Luvians in Lydia) in the Trojan War named Asios (an adjective meaning "Asian"); and also a marsh or lowland containing a marsh in Lydia as . According to many Muslims, the term came from Ancient Egypt's Queen Asiya, the adoptive mother of Moses. History The history of Asia can be seen as the distinct histories of several peripheral coastal regions: East Asia, South Asia, Southeast Asia and the Middle East, linked by the interior mass of the Central Asian steppes. The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley and the Yellow River shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states and empires developed in these lowlands. The central steppe region had long been inhabited by horse-mounted nomads who could reach all areas of Asia from the steppes. The earliest postulated expansion out of the steppe is that of the Indo-Europeans, who spread their languages into the Middle East, South Asia, and the borders of China, where the Tocharians resided. The northernmost part of Asia, including much of Siberia, was largely inaccessible to the steppe nomads, owing to the dense forests, climate and tundra. These areas remained very sparsely populated. The center and the peripheries were mostly kept separated by mountains and deserts. The Caucasus and Himalaya mountains and the Karakum and Gobi deserts formed barriers that the steppe horsemen could cross only with difficulty. While the urban city dwellers were more advanced technologically and socially, in many cases they could do little in a military aspect to defend against the mounted hordes of the steppe. However, the lowlands did not have enough open grasslands to support a large horsebound force; for this and other reasons, the nomads who conquered states in China, India, and the Middle East often found themselves adapting to the local, more affluent societies. The Islamic Caliphate's defeats of the Byzantine and Persian empires led to West Asia and southern parts of Central Asia and western parts of South Asia under its control during its conquests of the 7th century. The Mongol Empire conquered a large part of Asia in the 13th century, an area extending from China to Europe. Before the Mongol invasion, Song dynasty reportedly had approximately 120 million citizens; the 1300 census which followed the invasion reported roughly 60 million people. The Black Death, one of the most devastating pandemics in human history, is thought to have originated in the arid plains of central Asia, where it then travelled along the Silk Road. The Russian Empire began to expand into Asia from the 17th century, and would eventually take control of all of Siberia and most of Central Asia by the end of the 19th century. The Ottoman Empire controlled Anatolia, most of the Middle East, North Africa and the Balkans from the mid 16th century onwards. In the 17th century, the Manchu conquered China and established the Qing dynasty. The Islamic Mughal Empire and the Hindu Maratha Empire controlled much of India in the 16th and 18th centuries respectively. The Empire of Japan controlled most of East Asia and much of Southeast Asia, New Guinea and the Pacific islands until the end of World War II. Geography Asia is the largest continent on Earth. It covers 9% of the Earth's total surface area (or 30% of its land area), and has the longest coastline, at . Asia is generally defined as comprising the eastern four-fifths of Eurasia. It is located to the east of the Suez Canal and the Ural Mountains, and south of the Caucasus Mountains (or the Kuma–Manych Depression) and the Caspian and Black Seas. It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean. Asia is subdivided into 49 countries, five of them (Georgia, Azerbaijan, Russia, Kazakhstan and Turkey) are transcontinental countries lying partly in Europe. Geographically, Russia is partly in Asia, but is considered a European nation, both culturally and politically. The Gobi Desert is in Mongolia and the Arabian Desert stretches across much of the Middle East. The Yangtze River in China is the longest river in the continent. The Himalayas between Nepal and China is the tallest mountain range in the world. Tropical rainforests stretch across much of southern Asia and coniferous and deciduous forests lie farther north. Main regions There are various approaches to the regional division of Asia. The following subdivision into regions is used, among others, by the UN statistics agency UNSD. This division of Asia into regions by the United Nations is done solely for statistical reasons and does not imply any assumption about political or other affiliations of countries and territories. North Asia (Siberia) Central Asia (The 'stans) Western Asia (The Middle East or Near East and the Caucasus) South Asia (Indian subcontinent) East Asia (Far East) Southeast Asia (East Indies and Indochina) Climate Asia has extremely diverse climate features. Climates range from arctic and subarctic in Siberia to tropical in southern India and Southeast Asia. It is moist across southeast sections, and dry across much of the interior. Some of the largest daily temperature ranges on Earth occur in western sections of Asia. The monsoon circulation dominates across southern and eastern sections, due to the presence of the Himalayas forcing the formation of a thermal low which draws in moisture during the summer. Southwestern sections of the continent are hot. Siberia is one of the coldest places in the Northern Hemisphere, and can act as a source of arctic air masses for North America. The most active place on Earth for tropical cyclone activity lies northeast of the Philippines and south of Japan. Climate change Climate change is having major impacts on many countries in the continent. A survey carried out in 2010 by global risk analysis farm Maplecroft identified 16 countries that are extremely vulnerable to climate change. Each nation's vulnerability was calculated using 42 socio, economic and environmental indicators, which identified the likely climate change impacts during the next 30 years. The Asian countries of Bangladesh, India, the Philippines, Vietnam, Thailand, Pakistan, China and Sri Lanka were among the 16 countries facing extreme risk from climate change. Some shifts are already occurring. For example, in tropical parts of India with a semi-arid climate, the temperature increased by 0.4 °C between 1901 and 2003. A 2013 study by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) aimed to find science-based, pro-poor approaches and techniques that would enable Asia's agricultural systems to cope with climate change, while benefitting poor and vulnerable farmers. The study's recommendations ranged from improving the use of climate information in local planning and strengthening weather-based agro-advisory services, to stimulating diversification of rural household incomes and providing incentives to farmers to adopt natural resource conservation measures to enhance forest cover, replenish groundwater and use renewable energy. The ten countries of the Association of Southeast Asian Nations (ASEAN) – Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam – are among the most vulnerable to the effects of climate change in the world, however, ASEAN's climate mitigation efforts are not commensurate with the climate threats and risks it faces. Economy Asia has the largest continental economy by both GDP Nominal and PPP in the world, and is the fastest growing economic region. , the largest economies in Asia are China, Japan, India, South Korea, Indonesia and Turkey based on GDP in both nominal and PPP. Based on Global Office Locations 2011, Asia dominated the office locations with 4 of the top 5 being in Asia: Hong Kong, Singapore, Tokyo and Seoul. Around 68 percent of international firms have an office in Hong Kong. In the late 1990s and early 2000s, the economies of China and India grew rapidly, both with an average annual growth rate of more than 8%. Other recent very-high-growth nations in Asia include Israel, Malaysia, Indonesia, Bangladesh, Thailand, Vietnam, and the Philippines, and mineral-rich nations such as Kazakhstan, Turkmenistan, Iran, Brunei, the United Arab Emirates, Qatar, Kuwait, Saudi Arabia, Bahrain and Oman. According to economic historian Angus Maddison in his book The World Economy: A Millennial Perspective, India had the world's largest economy during 0 BCE and 1000 BCE. Historically, India was the largest economy in the world for most of the two millennia from the 1st until 19th century, contributing 25% of the world's industrial output. China was the largest and most advanced economy on earth for much of recorded history and shared the mantle with India. For several decades in the late twentieth century Japan was the largest economy in Asia and second-largest of any single nation in the world, after surpassing the Soviet Union (measured in net material product) in 1990 and Germany in 1968. (NB: A number of supernational economies are larger, such as the European Union (EU), the North American Free Trade Agreement (NAFTA) or APEC). This ended in 2010 when China overtook Japan to become the world's second largest economy. In the late 1980s and early 1990s, Japan's GDP was almost as large (current exchange rate method) as that of the rest of Asia combined. In 1995, Japan's economy nearly equaled that of the US as the largest economy in the world for a day, after the Japanese currency reached a record high of 79 yen/US$. Economic growth in Asia since World War II to the 1990s had been concentrated in Japan as well as the four regions of South Korea, Taiwan, Hong Kong and Singapore located in the Pacific Rim, known as the Asian tigers, which have now all received developed country status, having the highest GDP per capita in Asia. It is forecasted that India will overtake Japan in terms of nominal GDP by 2025. By 2027, according to Goldman Sachs, China will have the largest economy in the world. Several trade blocs exist, with the most developed being the Association of Southeast Asian Nations. Asia is the largest continent in the world by a considerable margin, and it is rich in natural resources, such as petroleum, forests, fish, water, rice, copper and silver. Manufacturing in Asia has traditionally been strongest in East and Southeast Asia, particularly in China, Taiwan, South Korea, Japan, India, the Philippines, and Singapore. Japan and South Korea continue to dominate in the area of multinational corporations, but increasingly the PRC and India are making significant inroads. Many companies from Europe, North America, South Korea and Japan have operations in Asia's developing countries to take advantage of its abundant supply of cheap labour and relatively developed infrastructure. According to Citigroup 9 of 11 Global Growth Generators countries came from Asia driven by population and income growth. They are Bangladesh, China, India, Indonesia, Iraq, Mongolia, the Philippines, Sri Lanka and Vietnam. Asia has three main financial centers: Hong Kong, Tokyo and Singapore. Call centers and business process outsourcing (BPOs) are becoming major employers in India and the Philippines due to the availability of a large pool of highly skilled, English-speaking workers. The increased use of outsourcing has assisted the rise of India and the China as financial centers. Due to its large and extremely competitive information technology industry, India has become a major hub for outsourcing. Trade between Asian countries and countries on other continents is largely carried out on the sea routes that are important for Asia. Individual main routes have emerged from this. The main route leads from the Chinese coast south via Hanoi to Jakarta, Singapore and Kuala Lumpur through the Strait of Malacca via the Sri Lankan Colombo to the southern tip of India via Malé to East Africa Mombasa, from there to Djibouti, then through the Red Sea over the Suez Canal into Mediterranean, there via Haifa, Istanbul and Athens to the upper Adriatic to the northern Italian hub of Trieste with its rail connections to Central and Eastern Europe or further to Barcelona and around Spain and France to the European northern ports. A far smaller part of the goods traffic runs via South Africa to Europe. A particularly significant part of the Asian goods traffic is carried out across the Pacific towards Los Angeles and Long Beach. In contrast to the sea routes, the Silk Road via the land route to Europe is on the one hand still under construction and on the other hand is much smaller in terms of scope. Intra-Asian trade, including sea trade, is growing rapidly. In 2010, Asia had 3.3 million millionaires (people with net worth over US$1 million excluding their homes), slightly below North America with 3.4 million millionaires. Last year Asia had toppled Europe. Citigroup in The Wealth Report 2012 stated that Asian centa-millionaire overtook North America's wealth for the first time as the world's "economic center of gravity" continued moving east. At the end of 2011, there were 18,000 Asian people mainly in Southeast Asia, China and Japan who have at least $100 million in disposable assets, while North America with 17,000 people and Western Europe with 14,000 people. Tourism With growing Regional Tourism with domination of Chinese visitors, MasterCard has released Global Destination Cities Index 2013 with 10 of 20 are dominated by Asia and Pacific Region Cities and also for the first time a city of a country from Asia (Bangkok) set in the top-ranked with 15.98 million international visitors. Demographics East Asia had by far the strongest overall Human Development Index (HDI) improvement of any region in the world, nearly doubling average HDI attainment over the past 40 years, according to the report's analysis of health, education and income data. China, the second highest achiever in the world in terms of HDI improvement since 1970, is the only country on the "Top 10 Movers" list due to income rather than health or education achievements. Its per capita income increased a stunning 21-fold over the last four decades, also lifting hundreds of millions out of income poverty. Yet it was not among the region's top performers in improving school enrollment and life expectancy. Nepal, a South Asian country, emerges as one of the world's fastest movers since 1970 mainly due to health and education achievements. Its present life expectancy is 25 years longer than in the 1970s. More than four of every five children of school age in Nepal now attend primary school, compared to just one in five 40 years ago. Hong Kong ranked highest among the countries grouped on the HDI (number 7 in the world, which is in the "very high human development" category), followed by Singapore (9), Japan (19) and South Korea (22). Afghanistan (155) ranked lowest amongst Asian countries out of the 169 countries assessed. Languages Asia is home to several language families and many language isolates. Most Asian countries have more than one language that is natively spoken. For instance, according to Ethnologue, more than 600 languages are spoken in Indonesia, more than 800 languages spoken in India, and more than 100 are spoken in the Philippines. China has many languages and dialects in different provinces. Religions Many of the world's major religions have their origins in Asia, including the five most practiced in the world (excluding irreligion), which are Christianity, Islam, Hinduism, Chinese folk religion (classified as Confucianism and Taoism), and Buddhism respectively. Asian mythology is complex and diverse. The story of the Great Flood for example, as presented to Jews in the Hebrew Bible in the narrative of Noah—and later to Christians in the Old Testament, and to Muslims in the Quran—is earliest found in Mesopotamian mythology, in the Enûma Eliš and Epic of Gilgamesh. Hindu mythology similarly tells about an avatar of Vishnu in the form of a fish who warned Manu of a terrible flood. Ancient Chinese mythology also tells of a Great Flood spanning generations, one that required the combined efforts of emperors and divinities to control. Abrahamic The Abrahamic religions including Judaism, Christianity, Islam, Druze faith, and Baháʼí Faith originated in West Asia. Judaism, the oldest of the Abrahamic faiths, is practiced primarily in Israel, the indigenous homeland and historical birthplace of the Hebrew nation: which today consists both of those Jews who remained in the Middle East and those who returned from diaspora in Europe, North America, and other regions; though various diaspora communities persist worldwide. Jews are the predominant ethnic group in Israel (75.6%) numbering at about 6.1 million, although the levels of adherence to Jewish religion vary. Outside of Israel there are small ancient Jewish communities in Turkey (17,400), Azerbaijan (9,100), Iran (8,756), India (5,000) and Uzbekistan (4,000), among many other places. In total, there are 14.4–17.5 million (2016, est.) Jews alive in the world today, making them one of the smallest Asian minorities, at roughly 0.3 to 0.4 percent of the total population of the continent. Christianity is a widespread religion in Asia with more than 286 million adherents according to Pew Research Center in 2010, and nearly 364 million according to Britannica Book of the Year 2014. Constituting around 12.6% of the total population of Asia. In the Philippines and East Timor, Roman Catholicism is the predominant religion; it was introduced by the Spaniards and the Portuguese, respectively. In Armenia and Georgia, Eastern Orthodoxy is the predominant religion. In the Middle East, such as in the Levant, Anatolia and Fars, Syriac Christianity (Church of the East) and Oriental Orthodoxy are prevalent minority denominations, which are both Eastern Christian sects mainly adhered to Assyrian people or Syriac Christians. Vibrant indigenous minorities in Western Asia are adhering to the Eastern Catholic Churches and Eastern Orthodoxy. Saint Thomas Christians in India trace their origins to the evangelistic activity of Thomas the Apostle in the 1st century. Significant Christian communities also found in Central Asia, South Asia, Southeast Asia and East Asia. Islam, which originated in the Hejaz located in modern-day Saudi Arabia, is the second largest and most widely-spread religion in Asia with at least 1 billion Muslims constituting around 23.8% of the total population of Asia. With 12.7% of the world Muslim population, the country currently with the largest Muslim population in the world is Indonesia, followed by Pakistan (11.5%), India (10%), Bangladesh, Iran and Turkey. Mecca, Medina and Jerusalem are the three holiest cities for Islam in all the world. The Hajj and Umrah attract large numbers of Muslim devotees from all over the world to Mecca and Medina. Iran is the largest Shi'a country. The Druze Faith or Druzism originated in Western Asia, is a monotheistic religion based on the teachings of figures like Hamza ibn-'Ali ibn-Ahmad and Al-Hakim bi-Amr Allah, and Greek philosophers such as Plato and Aristotle. The number of Druze people worldwide is around one million, with about 45% to 50% live in Syria, 35% to 40% live in Lebanon, and less than 10% live in Israel, with recently there has been a growing Druze diaspora. The Baháʼí Faith originated in Asia, in Iran (Persia), and spread from there to the Ottoman Empire, Central Asia, India, and Burma during the lifetime of Bahá'u'lláh. Since the middle of the 20th century, growth has particularly occurred in other Asian countries, because Baháʼí activities in many Muslim countries has been severely suppressed by authorities. Lotus Temple is a big Baháʼí Temple in India. Indian and East Asian religions Almost all Asian religions have philosophical character and Asian philosophical traditions cover a large spectrum of philosophical thoughts and writings. Indian philosophy includes Hindu philosophy and Buddhist philosophy. They include elements of nonmaterial pursuits, whereas another school of thought from India, Cārvāka, preached the enjoyment of the material world. The religions of Hinduism, Buddhism, Jainism and Sikhism originated in India, South Asia. In East Asia, particularly in China and Japan, Confucianism, Taoism and Zen Buddhism took shape. , Hinduism has around 1.1 billion adherents. The faith represents around 25% of Asia's population and is the largest religion in Asia. However, it is mostly concentrated in South Asia. Over 80% of the populations of both India and Nepal adhere to Hinduism, alongside significant communities in Bangladesh, Pakistan, Bhutan, Sri Lanka and Bali, Indonesia. Many overseas Indians in countries such as Burma, Singapore and Malaysia also adhere to Hinduism. Buddhism has a great following in mainland Southeast Asia and East Asia. Buddhism is the religion of the majority of the populations of Cambodia (96%), Thailand (95%), Burma (80–89%), Japan (36–96%), Bhutan (75–84%), Sri Lanka (70%), Laos (60–67%) and Mongolia (53–93%). Taiwan (35–93%), South Korea (23–50%), Malaysia (19–21%), Nepal (9–11%), Vietnam (10–75%), China (20–50%), North Korea (2–14%), and small communities in India and Bangladesh. The Communist-governed countries of China, Vietnam and North Korea are officially atheist, thus the number of Buddhists and other religious adherents may be under-reported. Jainism is found mainly in India and in overseas Indian communities such as the United States and Malaysia. Sikhism is found in Northern India and amongst overseas Indian communities in other parts of Asia, especially Southeast Asia. Confucianism is found predominantly in Mainland China, South Korea, Taiwan and in overseas Chinese populations. Taoism is found mainly in Mainland China, Taiwan, Malaysia and Singapore. In many Chinese communities, Taoism is easily syncretized with Mahayana Buddhism, thus exact religious statistics are difficult to obtain and may be understated or overstated. Modern conflicts Some of the events pivotal in the Asia territory related to the relationship with the outside world in the post-Second World War were: The Partition of India The Chinese Civil War The Kashmir conflict The Balochistan Conflict The Naxalite–Maoist insurgency in India The Korean War The French Indochina War The Vietnam War The Indonesia–Malaysia confrontation The 1959 Tibetan uprising The Sino-Vietnamese War The Bangladesh Liberation War The Yom Kippur War The Xinjiang conflict The Iranian Revolution The Soviet–Afghan War The Iran–Iraq War The Cambodian Killing Fields The Insurgency in Laos The Lebanese Civil War The Sri Lankan Civil War The 1988 Maldives coup d'état The Dissolution of the Soviet Union The Gulf War The Nepalese Civil War The Indo-Pakistani wars and conflicts The West Papua conflict The First Nagorno-Karabakh War The 1989 Tiananmen Square protests The Indonesian occupation of East Timor The 1999 Pakistani coup d'état The War in Afghanistan The Iraq War The South Thailand insurgency The 2006 Thai coup d'état The Burmese Civil War The Saffron Revolution The Kurdish–Turkish conflict The Arab Spring The Israeli–Palestinian conflict The Arab–Israeli conflict The Syrian Civil War The Sino-Indian War The 2014 Thai coup d'état The Moro conflict in the Philippines The Islamic State of Iraq and the Levant The Turkish invasion of Syria The Rohingya crisis in Myanmar The Saudi Arabian-led intervention in Yemen The Hong Kong protests The 2020 China–India skirmishes Culture The culture of Asia is a diverse blend of customs and traditions that have been practiced by the various ethnic groups of the continent for centuries. The continent is divided into six geographic sub-regions: Central Asia, East Asia, North Asia, South Asia, Southeast Asia, and West Asia. These regions are defined by their cultural similarities, including common religions, languages, and ethnicities. West Asia, also known as Southwest Asia or the Middle East, has cultural roots in the ancient civilizations of the Fertile Crescent and Mesopotamia, which gave rise to the Persian, Arab, Ottoman empires, as well as the Abrahamic religions of Judaism and Islam. These civilizations, which are located in the Hilly flanks, are among the oldest in the world, with evidence of farming dating back to around 9000 BCE. Despite the challenges posed by the vast size of the continent and the presence of natural barriers such as deserts and mountain ranges, trade and commerce have helped to create a Pan-Asian culture that is shared across the region. Nobel prizes The polymath Rabindranath Tagore, a Bengali poet, dramatist, and writer from Santiniketan, now in West Bengal, India, became in 1913 the first Asian Nobel laureate. He won his Nobel Prize in Literature for notable impact his prose works and poetic thought had on English, French, and other national literatures of Europe and the Americas. He is also the writer of the national anthems of Bangladesh and India. Other Asian writers who won Nobel Prize for literature include Yasunari Kawabata (Japan, 1968), Kenzaburō Ōe (Japan, 1994), Gao Xingjian (China, 2000), Orhan Pamuk (Turkey, 2006), and Mo Yan (China, 2012). Some may consider the American writer, Pearl S. Buck, an honorary Asian Nobel laureate, having spent considerable time in China as the daughter of missionaries, and based many of her novels, namely The Good Earth (1931) and The Mother (1933), as well as the biographies of her parents for their time in China, The Exile and Fighting Angel, all of which earned her the Literature prize in 1938. Also, Mother Teresa of India and Shirin Ebadi of Iran were awarded the Nobel Peace Prize for their significant and pioneering efforts for democracy and human rights, especially for the rights of women and children. Ebadi is the first Iranian and the first Muslim woman to receive the prize. Another Nobel Peace Prize winner is Aung San Suu Kyi from Burma for her peaceful and non-violent struggle under a military dictatorship in Burma. She is a nonviolent pro-democracy activist and leader of the National League for Democracy in Burma (Myanmar) and a noted prisoner of conscience. She is a Buddhist and was awarded the Nobel Peace Prize in 1991. Chinese dissident Liu Xiaobo was awarded the Nobel Peace Prize for "his long and non-violent struggle for fundamental human rights in China" on 8 October 2010. He is the first Chinese citizen to be awarded a Nobel Prize of any kind while residing in China. In 2014, Kailash Satyarthi from India and Malala Yousafzai from Pakistan were awarded the Nobel Peace Prize "for their struggle against the suppression of children and young people and for the right of all children to education". Sir C.V. Raman is the first Asian to get a Nobel prize in Sciences. He won the Nobel Prize in Physics "for his work on the scattering of light and for the discovery of the effect named after him". Japan has won the most Nobel Prizes of any Asian nation with 24 followed by India which has won 13. Amartya Sen, (born 3 November 1933) is an Indian economist who was awarded the 1998 Nobel Memorial Prize in Economic Sciences for his contributions to welfare economics and social choice theory, and for his interest in the problems of society's poorest members. Other Asian Nobel Prize winners include Subrahmanyan Chandrasekhar, Abdus Salam, Malala Yousafzai, Robert Aumann, Menachem Begin, Aaron Ciechanover, Avram Hershko, Daniel Kahneman, Shimon Peres, Yitzhak Rabin, Ada Yonath, Yasser Arafat, José Ramos-Horta and Bishop Carlos Filipe Ximenes Belo of Timor Leste, Kim Dae-jung, and 13 Japanese scientists. Most of the said awardees are from Japan and Israel except for Chandrasekhar and Raman (India), Abdus Salam and Malala Yousafzai, (Pakistan), Arafat (Palestinian Territories), Kim (South Korea), and Horta and Belo (Timor Leste). In 2006, Dr. Muhammad Yunus of Bangladesh was awarded the Nobel Peace Prize for the establishment of Grameen Bank, a community development bank that lends money to poor people, especially women in Bangladesh. Dr. Yunus received his PhD in economics from Vanderbilt University, United States. He is internationally known for the concept of micro credit which allows poor and destitute people with little or no collateral to borrow money. The borrowers typically pay back money within the specified period and the incidence of default is very low. The Dalai Lama has received approximately eighty-four awards over his spiritual and political career. On 22 June 2006, he became one of only four people ever to be recognized with Honorary Citizenship by the Governor General of Canada.

Aruba

Aruba ( , , ), officially the Country of Aruba (; ), is a constituent country of the Kingdom of the Netherlands physically located in the mid-south of the Caribbean Sea, about north of the Venezuela peninsula of Paraguaná and northwest of Curaçao. It measures long from its northwestern to its southeastern end and across at its widest point. Together with Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands. Collectively, these and the other three Dutch substantial islands in the Caribbean are often called the Dutch Caribbean, of which Aruba has about one-third of the population. In 1986, it became a constituent country within the Kingdom of the Netherlands, and acquired the formal name the Country of Aruba. Aruba is one of the four countries that form the Kingdom of the Netherlands, along with the Netherlands, Curaçao, and Sint Maarten; the citizens of these countries are all Dutch nationals. Aruba has no administrative subdivisions, but, for census purposes, is divided into eight regions. Its capital is Oranjestad. Unlike much of the Caribbean region, Aruba has a dry climate and an arid, cactus-strewn landscape. The relatively warm and sunny weather, and the climate allow for related tourism activities all year round. Its area is and it is quite densely populated, with 108,166 inhabitants per the 2020 census. Etymology The name Aruba most likely came from the Caquetio Oruba which means "Well situated island", seeing as it was the Caquetio who were present on the island when it was first set foot upon by Alonso de Ojeda. Between 1529 and the signing of the Treaty of Westphalia (1648), the name "Isla de Oruba" was used for the island by the Spanish. After the signing, the island was ceded to the Dutch and its name was changed to Aruba. There were many different names for Aruba used by other Amerindian groups, all of which could have contributed to the present-day name Aruba. Another Caquetio name for the island was Oibubia which means "Guided island". The Taino name for the island was Arubeira. The Kalinago also had two names for the island Ora Oubao which means "Shell island" and Oirubae which means "Companion of Curaçao". A common misconception is that the name Aruba came from the Spanish Oro hubo which means "There was gold". However the Spanish found no gold on Aruba during the time of their occupation, nicknaming Aruba and the rest of the ABC islands Islas Inútiles, meaning "Useless islands" due to the lack of gold. It was not until much later in 1824 that gold was found on Aruba by Willem Rasmijn, starting the Aruban Gold Rush. Another early Spanish name for Aruba was Isla de Brasil, named as such because of the many Brazilwood trees that grew on the island. History Pre-colonial era There has been a human presence on Aruba from as early as circa 2000 BC. The first identifiable group are the Arawak Caquetío Amerindians who migrated from South America about 1000 AD. Archaeological evidence suggests continuing links between these native Arubans and Amerindian peoples of mainland South America. Spanish colonization The first Europeans to visit Aruba were Amerigo Vespucci and Alonso de Ojeda in 1499, who claimed the island for Spain. Both men described Aruba as an "island of giants", remarking on the comparatively large stature of the native Caquetíos. Vespucci returned to Spain with stocks of cotton and brazilwood from the island and described houses built into the ocean. Vespucci and Ojeda's tales spurred interest in Aruba, and the Spanish began colonising the island. Alonso de Ojeda was appointed the island's first governor in 1508. From 1513 the Spanish began enslaving the Caquetíos, sending many to a life of forced labour in the mines of Hispaniola. The island's low rainfall and arid landscape meant that it was not considered profitable for a slave-based plantation system, so the type of large-scale slavery so common on other Caribbean islands never became established on Aruba. Early Dutch period The Netherlands seized Aruba from Spain in 1636 in the course of the Thirty Years' War. Peter Stuyvesant, later appointed to New Amsterdam (New York), was the first Dutch governor. Those Arawak who had survived the depredations of the Spanish were allowed to farm and graze livestock, with the Dutch using the island as a source of meat for their other possessions in the Caribbean. Aruba's proximity to South America resulted in interactions with the cultures of the coastal areas; for example, architectural similarities can be seen between the 19th-century parts of Oranjestad and the nearby Venezuelan city of Coro in Falcón State. Historically, Dutch was not widely spoken on the island outside of colonial administration; its use increased in the late 19th and early 20th centuries. Students on Curaçao, Aruba, and Bonaire were taught predominantly in Spanish until the late 18th century. During the Napoleonic Wars, the British Empire took control of the island, occupying it between 1806 and 1816, before handing it back to the Dutch as per the terms of the Anglo-Dutch Treaty of 1814. Aruba subsequently became part of the Colony of Curaçao and Dependencies along with Bonaire. During the 19th century, an economy based on gold mining, phosphate production and aloe vera plantations developed, but the island remained a relatively poor backwater. 20th and 21st centuries The first oil refinery in Aruba was built in 1928 by Royal Dutch Shell. The facility was built just to the west of the capital city, Oranjestad, and was commonly called the Eagle. Immediately following that, another refinery was built by Lago Oil and Transport Company, in an area now known as San Nicolas on the east end of Aruba. The refineries processed crude oil from the vast Venezuelan oil fields, bringing greater prosperity to the island. The refinery on Aruba grew to become one of the largest in the world. During World War II, the Netherlands was occupied by Nazi Germany. In 1940, the oil facilities in Aruba came under the administration of the Dutch government-in-exile in London, causing them to be attacked by the German navy in 1942. In August 1947, Aruba formulated its first Staatsreglement (constitution) for Aruba's status aparte as an autonomous state within the Kingdom of the Netherlands, prompted by the efforts of Henny Eman, a noted Aruban politician. By 1954, the Charter of the Kingdom of the Netherlands was established, providing a framework for relations between Aruba and the rest of the Kingdom. That created the Netherlands Antilles, which united all of the Dutch colonies in the Caribbean into one administrative structure. Many Arubans were unhappy with the arrangement, however, as the new polity was perceived as being dominated by Curaçao. In 1972, at a conference in Suriname, Betico Croes, a politician from Aruba, proposed the creation of a Dutch Commonwealth of four states: Aruba, the Netherlands, Suriname, and the Netherlands Antilles, each to have its own nationality. Backed by his newly created party, the Movimiento Electoral di Pueblo, Croes sought greater autonomy for Aruba, with the long-term goal of independence, adopting the trappings of an independent state in 1976 with the creation of a flag and national anthem. In March 1977, a referendum was held with the support of the United Nations. 82% of the participants voted for complete independence from the Netherlands. Tensions mounted as Croes stepped up the pressure on the Dutch government by organising a general strike in 1977. Croes later met with Dutch Prime Minister Joop den Uyl, with the two sides agreeing to assign the Institute of Social Studies in The Hague to prepare a study for independence, entitled Aruba en Onafhankelijkheid, achtergronden, modaliteiten, en mogelijkheden; een rapport in eerste aanleg (Aruba and independence, backgrounds, modalities, and opportunities; a preliminary report) (1978). Autonomy In March 1983, Aruba reached an official agreement within the Kingdom for its independence, to be developed in a series of steps as the Crown granted increasing autonomy. In August 1985, Aruba drafted a constitution that was unanimously approved. On 1 January 1986, after elections were held for its first parliament, Aruba seceded from the Netherlands Antilles, officially becoming a country of the Kingdom of the Netherlands, with full independence planned for 1996. However, Croes was seriously injured in a traffic accident in 1985, slipping into a coma. He died in 1986, never seeing the enacting of status aparte for Aruba for which he had worked over many years. After his death, Croes was proclaimed Libertador di Aruba. Croes' successor, Henny Eman, of the Aruban People's Party (AVP), became the first Prime Minister of Aruba. In 1985, Aruba's oil refinery had closed. It had provided Aruba with 30 percent of its real income and 50 percent of government revenue. The significant blow to the economy led to a push for a dramatic increase in tourism, and that sector has expanded to become the island's largest industry. At a convention in The Hague in 1990, at the request of Aruba's Prime Minister Nelson Oduber, the governments of Aruba, the Netherlands, and the Netherlands Antilles postponed indefinitely Aruba's transition to full independence. The article scheduling Aruba's complete independence was rescinded in 1995, although it was decided that the process could be revived after another referendum. Geography Aruba is a generally flat, riverless island in the Leeward Antilles island arc of the Lesser Antilles in the southern part of the Caribbean. It lies west of Curaçao and north of Venezuela's Paraguaná Peninsula. Aruba has white sandy beaches on the western and southern coasts of the island, relatively sheltered from fierce ocean currents. This is where the bulk of the population live and where most tourist development has occurred. The northern and eastern coasts, lacking this protection, are considerably more battered by the sea and have been left largely untouched. As of 2022, Aruba only has 2.3% of forest-covered land area and only 0.5% of protected natural area. The hinterland of the island features some rolling hills, such as Hooiberg at and Mount Jamanota, the highest on the island at above sea level. Oranjestad, the capital, is located at . The Natural Bridge was a large, naturally formed limestone bridge on the island's north shore. It was a popular tourist destination until its collapse in 2005. Cities and towns The island, with a population of about 116,600 people (1 January 2019 estimate) does not have major cities. It is divided into six districts. Most of the island's population resides in or around the two major city-like districts of Oranjestad (the capital) and San Nicolaas. Oranjestad and San Nicolaas are both divided into two districts for census purposes only. The districts are as follows: Noord Oranjestad (East and West) Paradera San Nicolaas (North and South) Santa Cruz Savaneta Fauna The isolation of Aruba from the mainland of South America has fostered the evolution of multiple endemic animals. The island provides a habitat for the endemic Aruban Whiptail and Aruba Rattlesnake, as well as an endemic subspecies of Burrowing Owl and Brown-throated Parakeet. Flora The flora of Aruba differs from the typical tropical island vegetation. Xeric scrublands are common, with various forms of cacti, thorny shrubs, and evergreens. Aloe vera is also present, its economic importance earning it a place on the coat of arms of Aruba. Cacti like Melocactus and Opuntia are represented on Aruba by species like Opuntia stricta. Trees like Caesalpinia coriaria and Vachellia tortuosa are drought tolerant. Climate and natural hazards By the Köppen climate classification, Aruba has a hot semi-arid climate (Köppen BSh). Rainfall is scarce, only per year; in particular, rainy season is drier than it normally is in tropical climates; during the dry season, it almost never rains. Owing to the scarcity of rainfall, the landscape of Aruba is arid. Mean monthly temperature in Oranjestad varies little from to , moderated by constant trade winds from the Atlantic Ocean, which come from the north-east. Yearly rainfall barely exceeds in Oranjestad, although it is extremely variable and can range from as little as during strong El Niño years (e.g. 1911/1912, 1930/1931, 1982/1983, 1997/1998) to over in La Niña years like 1933/1934, 1970/1971 or 1988/1989. Aruba is south of the typical latitudes of hurricanes but was affected by two in their early stages in late 2020. Demographics In terms of country of birth, the population is estimated to be 66% Aruban, 9.1% Colombian, 4.3% Dutch, 4.1% Dominican, 3.2% Venezuelan, 2.2% Curaçaoan, 1.5% Haitian, 1.2% Surinamese, 1.1% Peruvian, 1.1% Chinese, 6.2% other. In terms of ethnic composition, the population is estimated to be 75% mestizo, 15% black and 10% other ethnicities. Arawak heritage is stronger on Aruba than on most Caribbean islands; although no full-blooded Aboriginals remain, the features of the islanders clearly indicate their genetic Arawak heritage. Most of the population is descended from Caquetio Indians, African slaves, and Dutch settlers, and to a lesser extent the various other groups that have settled on the island over time, such as the Spanish, Portuguese, English, French, and Sephardic Jews. Recently, there has been substantial immigration to the island from neighbouring South American and Caribbean nations, attracted by the higher paid jobs. In 2007, new immigration laws were introduced to help control the growth of the population by restricting foreign workers to a maximum of three years residency on the island. Most notable are those from Venezuela, which lies just to the south. In 2019, recently arrived Venezuelan refugees were estimated to number around 17,000, accounting for some 15% of the island's population. Language Aruba's official languages are Dutch and Papiamento. While Dutch is the sole language for all administration and legal matters, Papiamento is the predominant language used on Aruba. Papiamento is a Portuguese- and Spanish-based creole language, spoken on Aruba, Bonaire, and Curaçao, that also incorporates words from Dutch and various West African languages. English and Spanish are also spoken, their usage having grown due to tourism. Other common languages spoken, based on the size of their community, are Portuguese, Cantonese, French and German. In recent years, the government of Aruba has shown an increased interest in acknowledging the cultural and historical importance of Papiamento. Although spoken Papiamento is fairly similar among the several Papiamento-speaking islands, there is a big difference in written Papiamento: The orthography differs per island, with Aruba using etymological spelling, and Curaçao and Bonaire a phonetic spelling. The book Buccaneers of America, first published in 1678, states through eyewitness account that the natives on Aruba spoke Spanish already. Spanish became an important language in the 18th century due to the close economic ties with Spanish colonies in what are now Venezuela and Colombia. Venezuelan TV networks are received on the island, and Aruba also has significant Venezuelan and Colombian communities. Around 13% of the population today speaks Spanish natively. Use of English dates to the early 19th century, when the British took Curaçao, Aruba, and Bonaire. When Dutch rule resumed in 1815, officials already noted wide use of the language. Aruba has newspapers published in Papiamento: Diario, Bon Dia, Solo di Pueblo, and Awe Mainta; English: Aruba Daily, Aruba Today, and The News; and Dutch: Amigoe. Aruba has 18 radio stations (two AM and 16 FM) and two television stations (Telearuba and Channel 22). Religion Roman Catholicism is the dominant religion, practised by about 75% of the population. Various Protestant denominations are also present on the island. Regions Aruba is cartographically split into eight for censuses; these regions have no administrative function; some allude to parishes which include a few charitable community facilities: Government Along with the Netherlands, Curaçao, and Sint Maarten, Aruba is a constituent country of the Kingdom of the Netherlands, with internal autonomy. Matters such as foreign affairs and defense are handled by the Netherlands. Aruba's politics take place within a framework of a 21-member Staten (Parliament) and an eight-member Cabinet; the Staten's 21 members are elected by direct, popular vote to serve a four-year term. The governor of Aruba is appointed for a six-year term by the monarch, and the prime minister and deputy prime minister are indirectly elected by the Staten for four-year terms. Aruba was formerly a part of the (now-defunct) Netherlands Antilles; however, it separated from that entity in 1986, gaining its own constitution. Aruba is designated as a member of the Overseas Countries and Territories (OCT) and is thus officially not a part of the European Union, though Aruba can and does receive support from the European Development Fund. Politics The Aruban legal system is based on the Dutch model. In Aruba, legal jurisdiction lies with the Gerecht in Eerste Aanleg (Court of First Instance) on Aruba, the Gemeenschappelijk Hof van Justitie van Aruba, Curaçao, Sint Maarten, en van Bonaire, Sint Eustatius en Saba (Joint Court of Justice of Aruba, Curaçao, Sint Maarten, and of Bonaire, Sint Eustatius and Saba) and the Hoge Raad der Nederlanden (Supreme Court of Justice of the Netherlands). The Korps Politie Aruba (Aruba Police Force) is the island's law enforcement agency and operates district precincts in Oranjestad, Noord, San Nicolaas, and Santa Cruz, where it is headquartered. Deficit spending has been a staple in Aruba's history, and modestly high inflation has been present as well. By 2006, the government's debt had grown to 1.883 billion Aruban florins. In 2006, the Aruban government changed several tax laws to reduce the deficit. Direct taxes have been converted to indirect taxes as proposed by the IMF. Foreign relations Aruba is one of the overseas countries and territories (OCT) of the European Union and maintains economic and cultural relations with the European Union and the United States. Aruba is also a member of several international organizations such as the International Monetary Fund and Interpol. Military Defence on Aruba is the responsibility of the Kingdom of the Netherlands. The Dutch Armed Forces that protect the island include the Navy, Marine Corps, and the Coastguard including a platoon sized national guard. All forces are stationed at Marines base in Savaneta. Furthermore, in 1999, the U.S. Department of Defense established a Forward Operating Location (FOL) at the airport. Education Aruba's educational system is patterned after the Dutch system of education. The government of Aruba finances the public national education system. Schools are a mixture of public and private, including the International School of Aruba, the Schakel College and mostly the Colegio Arubano. There are three medical schools, American University School of Medicine Aruba (AUSOMA), Aureus University School of Medicine and Xavier University School of Medicine, as well as its own national university, the University of Aruba. Economy The island's economy is dominated by four main industries: tourism, aloe export, petroleum refining, and offshore banking. Aruba has one of the highest standards of living in the Caribbean region. The GDP per capita (PPP) for Aruba was estimated to be $37,500 in 2017. Its main trading partners are Colombia, the United States, Venezuela, and the Netherlands. The agriculture and manufacturing sectors are fairly minimal. Gold mining was important in the 19th century. Aloe was introduced to Aruba in 1840 but did not become a big export until 1890. Cornelius Eman founded Aruba Aloe Balm, and over time the industry became very important to the economy. At one point, two-thirds of the island was covered in Aloe Vera fields, and Aruba became the largest exporter of aloe in the world. The industry continues today, though on a smaller scale. Access to biocapacity in Aruba is much lower than world average. In 2016, Aruba had 0.57 global hectares of biocapacity per person within its territory, much less than the world average of 1.6 global hectares per person. In 2016, Aruba used 6.5 global hectares of biocapacity per person - their ecological footprint of consumption. This means they use almost 12 times the biocapacity that Aruba contains. This is the extent of Aruba's biocapacity deficit. The official exchange rate of the Aruban florin is pegged to the US dollar at 1.80 florins to US$1. This fact, and the majority of tourists being US, means businesses of hotel and resort districts prefer to bank and trade with the consumer in US dollars. Aruba is a prosperous country. Unemployment is low (although the government has not published statistics since 2013) and per capita income is one of the highest in the Caribbean (approximately $24,087). At the end of 2018, the labor force participation rate was 56.6% for women. Until the mid-1980s, Aruba's main industry was oil refining. Then the refinery was shut down and the island's economy shifted towards tourism. Currently, Aruba receives about 1,235,673 (2007) guests per year, of which three-quarters are Americans. Tourism is mainly focused on the beaches and the sea. The refinery has been closed and restarted repeatedly during the last decades. In recent years a letter of intent was signed with CITGO (the US subsidiary of the Venezuelan state oil company PDVSA) to explore the possibility of reopening the refinery again. Until 2009, the Netherlands granted development aid to Aruba. This aid was mainly for law enforcement, education, administrative development, health care and sustainable economic development. This aid was discontinued at Aruba's request in 2009. Since 2015, however, a form of financial supervision has been reintroduced because Aruba's debt has risen sharply to over 80% of GDP. Aruba also has two free trade zones (Barcadera and Bushiri), where import and export and the movement of services are tax-free. Tourism Aruba has a large and well-developed tourism industry, receiving 1,082,000 tourists who stayed overnight in its territory in 2018. About of the Aruban gross national product is earned through tourism and related activities. Most tourists are from North America, with a market-share of 73.3%, followed by Latin America with 15.2% and Europe with 8.3%. In 2018, there were 40,231 visitors from the Netherlands. For private aircraft passengers bound for the United States, the United States Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) has a full pre-clearance facility since 1 February 2001 when Queen Beatrix Airport expanded. Since 2008, Aruba has been the only island to have this service for private flights. There are many luxury and lesser luxury hotels, concentrated mainly on the west coast beaches. In Palm Beach are the luxury hotels aimed at American tourists. This area is also called "Highrise-area", because most of the hotels are located in (by Aruban standards) high-rise buildings. Eagle Beach, a short distance from Palm Beach in the direction of Oranjestad, offers hotels on a somewhat smaller and more intimate scale in low-rise buildings, hence the name "lowrise-area". Oranjestad is the port for the many cruise ships that visit Aruba. The cruise industry is a very important pillar of tourism in Aruba, since during a cruise a large part of the passengers go ashore to visit the island. With 334 cruise calls, Aruba received 815,161 cruise tourists in 2018. The 2017/2018 cruise season brought $102.8 million to Aruba's economy. Oranjestad is also home to several luxury hotels, upscale shopping malls, tourist-oriented shopping streets, and hospitality facilities. The main street, called Caya G.F. (Betico) Croes, has been redesigned in recent years, including new paving, new palm trees and a streetcar line for tourists. Culture Aruba has a varied culture. According to the Bureau Burgelijke Stand en Bevolkingsregister (BBSB), in 2005 there were ninety-two different nationalities living on the island. Dutch influence can still be seen, as in the celebration of "Sinterklaas" on 5 and 6 December and other national holidays like 27 April, when in Aruba and the rest of the Kingdom of the Netherlands the King's birthday or "Dia di Rey" (Koningsdag) is celebrated. On 18 March, Aruba celebrates its National Day. Christmas and New Year's Eve are celebrated with the typical music and songs for gaitas for Christmas and the Dande for New Year, and ayaca, ponche crema, ham, and other typical foods and drinks. On 25 January, Betico Croes' birthday is celebrated. Dia di San Juan is celebrated on 24 June. Besides Christmas, the religious holy days of the Feast of the Ascension and Good Friday are also holidays on the island. The festival of Carnaval is also an important one in Aruba, as it is in many Caribbean and Latin American countries. Its celebration in Aruba started in the 1950s, influenced by the inhabitants from Venezuela and the nearby islands (Curaçao, St. Vincent, Trinidad, Barbados, St. Maarten, and Anguilla) who came to work for the oil refinery. Over the years, the Carnival Celebration has changed and now starts from the beginning of January until the Tuesday before Ash Wednesday, with a large parade on the last Sunday of the festivities (the Sunday before Ash Wednesday). Tourism from the United States has recently increased the visibility of American culture on the island, with such celebrations as Halloween in October and Thanksgiving Day in November. Architecture From the beginning of the colonization of the Netherlands until the beginning of the 20th century, the architecture in the most inhabited areas of Aruba was influenced by the Dutch colonial style and also some Spanish elements from the Catholic missionaries present in Aruba who later settled in Venezuela as well. After the boom of the oil industry and the tourist sector in the 20th century the architectural style of the island incorporated a more American and international influence. In addition, elements of the Art Deco style can still be seen in several buildings in San Nicolas. Therefore, it can be said that the island's architecture is a mixture of Spanish, Dutch, American and Caribbean influences. Infrastructure Aruba's Queen Beatrix International Airport is near Oranjestad. Aruba has four ports: Barcadera, the main cargo port, Paardenbaai, the cruise ship terminal in Oranjestad/Taratata, Commandeurs Baai (Commander's Bay) in Savaneta, and Sint Nicolaas Baai in San Nicolaas. Paardenbaai services all the cruise-ship lines such as Royal Caribbean, Carnival, NCL, Holland America, MSC Cruises, Costa Cruises, P&O Cruises and Disney. Nearly one million tourists enter this port per year. Aruba Ports Authority, owned and operated by the Aruban government, runs these seaports. Arubus is a government-owned bus company. Its buses operate from 3:30 a.m. until 12:30 a.m., 365 days a year. Private minibuses/people movers service zones such as the Hotel Area, San Nicolaas, Santa Cruz and Noord. A streetcar service runs on rails on the Mainstreet of Oranjestad. Utilities Water- en Energiebedrijf Aruba, N.V. (W.E.B.) produces potable water and power. Average daily consumption in Aruba is about 35600 m3/day., and average power generation is 104 MW. Besides production, WEB also takes care of the water distribution on the island. Elektriciteits Maatschappij Aruba, N.V. (N.V. Elmar) is the sole distributor of electricity on the island of Aruba. N.V. Elmar also offers its customers the opportunity to add solar panel or wind turbines. Together with W.E.B. Aruba N.V., both companies share the same parent holding which is Utilities Aruba N.V. Waste Management Sewage plant: there are 3 around the island; Zeewijk, Parkietenbos and Bubali. The one in Bubali (near the bird sanctuary) is 4 decades old and is processing over 8000 m3/day. Around double its original capacity of 4500 m3/day (due to Aruba's growth). Solid waste landfill: the major one (16 ha) is at Parkietenbos since the 1950. The capacity is between 130 to 150 kilotons per year. Sometimes there are huge spontaneous combustion creating pollution. Communications There are two telecommunications providers: government-based Setar, and privately owned Digicel. Digicel is Setar's competitor in wireless technology using the GSM platform.

Articles of Confederation

The Articles of Confederation and Perpetual Union was an agreement among the 13 states of the United States of America, formerly the Thirteen Colonies, that served as the nation's first frame of government. It was approved after much debate (between July 1776 and November 1777) by the Second Continental Congress on November 15, 1777, and sent to the states for ratification. The Articles of Confederation came into force on March 1, 1781, after ratification by all the states. A guiding principle of the Articles was to establish and preserve the independence and sovereignty of the states. The weak central government established by the Articles received only those powers which the former colonies had recognized as belonging to king and parliament. The document provided clearly written rules for how the states' league of friendship, known as the Perpetual Union, would be organized. During the ratification process, the Congress looked to the Articles for guidance as it conducted business, directing the war effort, conducting diplomacy with foreign states, addressing territorial issues and dealing with Native American relations. Little changed procedurally once the Articles of Confederation went into effect, as ratification did little more than constitutionalize what the Continental Congress had been doing. That body was renamed the Congress of the Confederation; but most Americans continued to call it the Continental Congress, since its organization remained the same. As the Confederation Congress attempted to govern the continually growing U.S. states, its delegates discovered that the limitations placed upon the central government (such as in assembling delegates, raising funds, and regulating commerce) rendered it ineffective at doing so. As the government's weaknesses became apparent, especially after Shays' Rebellion, some prominent political thinkers in the fledgling union began asking for changes to the Articles. Their hope was to create a stronger government. Initially, in September 1786, some states met to address interstate protectionist trade barriers between them. Shortly thereafter, as more states became interested in meeting to revise the Articles, a meeting was set in Philadelphia on May 25, 1787. This became the Constitutional Convention. Delegates quickly agreed that the defects of the frame of government could not be remedied by altering the Articles, and so went beyond their mandate by replacing it with a new constitution. On March 4, 1789, the government under the Articles was replaced with the federal government under the Constitution. The new Constitution provided for a much stronger federal government by establishing a chief executive (the president), courts, and taxing powers. Background and context The political push to increase cooperation among the then-loyal colonies began with the Albany Congress in 1754 and Benjamin Franklin's proposed Albany Plan, an inter-colonial collaboration to help solve mutual local problems. Over the next two decades, some of the basic concepts it addressed would strengthen; others would weaken, especially in the degree of loyalty (or lack thereof) owed the Crown. Civil disobedience resulted in coercive and quelling measures, such as the passage of what the colonials referred to as the Intolerable Acts in the British Parliament, and armed skirmishes which resulted in dissidents being proclaimed rebels. These actions eroded the number of Crown Loyalists (Tories) among the colonials and, together with the highly effective propaganda campaign of the Patriot leaders, caused an increasing number of colonists to begin agitating for independence from the mother country. In 1775, with events outpacing communications, the Second Continental Congress began acting as the provisional government for the United Colonies. It was an era of constitution writing—most states were busy at the task—and leaders felt the new nation must have a written constitution; a "rulebook" for how the new nation should function. During the war, Congress exercised an unprecedented level of political, diplomatic, military and economic authority. It adopted trade restrictions, established and maintained an army, issued fiat money, created a military code and negotiated with foreign governments. To transform themselves from outlaws into a legitimate nation, the colonists needed international recognition for their cause and foreign allies to support it. In early 1776, Thomas Paine argued in the closing pages of the first edition of Common Sense that the "custom of nations" demanded a formal declaration of American independence if any European power were to mediate a peace between the Americans and Great Britain. The monarchies of France and Spain, in particular, could not be expected to aid those they considered rebels against another legitimate monarch. Foreign courts needed to have American grievances laid before them persuasively in a "manifesto" which could also reassure them that the Americans would be reliable trading partners. Without such a declaration, Paine concluded, "[t]he custom of all courts is against us, and will be so, until, by an independence, we take rank with other nations." Beyond improving their existing association, the records of the Second Continental Congress show that the need for a declaration of independence was intimately linked with the demands of international relations. On June 7, 1776, Richard Henry Lee introduced a resolution before the Continental Congress declaring the colonies independent; at the same time, he also urged Congress to resolve "to take the most effectual measures for forming foreign Alliances" and to prepare a plan of confederation for the newly independent states. Congress then created three overlapping committees to draft the Declaration, a model treaty, and the Articles of Confederation. The Declaration announced the states' entry into the international system; the model treaty was designed to establish amity and commerce with other states; and the Articles of Confederation, which established "a firm league" among the thirteen free and independent states, constituted an international agreement to set up central institutions for the conduct of vital domestic and foreign affairs. Drafting On June 12, 1776, a day after appointing the Committee of Five to prepare a draft of the Declaration of Independence, the Second Continental Congress resolved to appoint a committee of 13 with one representative from each colony to prepare a draft of a constitution for a union of the states. The committee was made up of the following individuals: John Dickinson (Pennsylvania, chairman of the committee) Samuel Adams (Massachusetts) Josiah Bartlett (New Hampshire) Button Gwinnett (Georgia) Joseph Hewes (North Carolina) Stephen Hopkins (Rhode Island) Robert R. Livingston (New York) Thomas McKean (Delaware) Thomas Nelson (Virginia) Edward Rutledge (South Carolina) Roger Sherman (Connecticut) Thomas Stone (Maryland) Francis Hopkinson (New Jersey, added to the committee last) The committee met frequently, and chairman John Dickinson presented their results to the Congress on July 12, 1776. Afterward, there were long debates on such issues as state sovereignty, the exact powers to be given to Congress, whether to have a judiciary, western land claims, and voting procedures. To further complicate work on the constitution, Congress was forced to leave Philadelphia twice, for Baltimore, Maryland, in the winter of 1776, and later for Lancaster then York, Pennsylvania, in the fall of 1777, to evade advancing British troops. Even so, the committee continued with its work. The final draft of the Articles of Confederation and Perpetual Union was completed on November 15, 1777. Consensus was achieved by including language guaranteeing that each state retained its sovereignty, leaving the matter of western land claims in the hands of the individual states, including language stating that votes in Congress would be en bloc by state, and establishing a unicameral legislature with limited and clearly delineated powers. Ratification The Articles of Confederation was submitted to the states for ratification in late November 1777. The first state to ratify was Virginia on December 16, 1777; 12 states had ratified the Articles by February 1779, 14 months into the process. The lone holdout, Maryland, refused to go along until the landed states, especially Virginia, had indicated they were prepared to cede their claims west of the Ohio River to the Union. It would be two years before the Maryland General Assembly became satisfied that the various states would follow through, and voted to ratify. During this time, Congress observed the Articles as its de facto frame of government. Maryland finally ratified the Articles on February 2, 1781. Congress was informed of Maryland's assent on March 1, and officially proclaimed the Articles of Confederation to be the law of the land. The several states ratified the Articles of Confederation on the following dates: Article summaries The Articles of Confederation contain a preamble, thirteen articles, a conclusion, and a signatory section. The individual articles set the rules for current and future operations of the confederation's central government. Under the Articles, the states retained sovereignty over all governmental functions not specifically relinquished to the national Congress, which was empowered to make war and peace, negotiate diplomatic and commercial agreements with foreign countries, and to resolve disputes between the states. The document also stipulates that its provisions "shall be inviolably observed by every state" and that "the Union shall be perpetual". Summary of the purpose and content of each of the 13 articles: Establishes the name of the confederation with these words: "The stile of this confederacy shall be 'The United States of America.'" Asserts the sovereignty of each state, except for the specific powers delegated to the confederation government: "Each state retains its sovereignty, freedom, and independence, and every power, jurisdiction, and right, which is not by this Confederation expressly delegated." Declares the purpose of the confederation: "The said States hereby severally enter into a firm league of friendship with each other, for their common defense, the security of their liberties, and their mutual and general welfare, binding themselves to assist each other, against all force offered to, or attacks made upon them, or any of them, on account of religion, sovereignty, trade, or any other pretense whatever." Elaborates upon the intent "to secure and perpetuate mutual friendship and intercourse among the people of the different States in this union," and to establish equal treatment and freedom of movement for the free inhabitants of each state to pass unhindered between the states, excluding "paupers, vagabonds, and fugitives from justice." All these people are entitled to equal rights established by the state into which they travel. If a crime is committed in one state and the perpetrator flees to another state, he will be extradited to and tried in the state in which the crime was committed. Allocates one vote in the Congress of the Confederation (the "United States in Congress Assembled") to each state, which is entitled to a delegation of between two and seven members. Members of Congress are to be appointed by state legislatures. No congressman may serve more than three out of any six years. Only the central government may declare war, or conduct foreign political or commercial relations. No state or official may accept foreign gifts or titles, and granting any title of nobility is forbidden to all. No states may form any sub-national groups. No state may tax or interfere with treaty stipulations already proposed. No state may wage war without permission of Congress, unless invaded or under imminent attack on the frontier; no state may maintain a peacetime standing army or navy, unless infested by pirates, but every State is required to keep ready, a well-trained, disciplined, and equipped militia. Whenever an army is raised for common defense, the state legislatures shall assign military ranks of colonel and below. Expenditures by the United States of America will be paid with funds raised by state legislatures, and apportioned to the states in proportion to the real property values of each. Powers and functions of the United States in Congress Assembled. Grants to the United States in Congress assembled the sole and exclusive right and power to determine peace and war; to exchange ambassadors; to enter into treaties and alliances, with some provisos; to establish rules for deciding all cases of captures or prizes on land or water; to grant letters of marque and reprisal (documents authorizing privateers) in times of peace; to appoint courts for the trial of pirates and crimes committed on the high seas; to establish courts for appeals in all cases of captures, but no member of Congress may be appointed a judge; to set weights and measures (including coins), and for Congress to serve as a final court for disputes between states. The court will be composed of jointly appointed commissioners or Congress shall appoint them. Each commissioner is bound by oath to be impartial. The court's decision is final. Congress shall regulate the post offices; appoint officers in the military; and regulate the armed forces. The United States in Congress assembled may appoint a president who shall not serve longer than one year per three-year term of the Congress. Congress may request requisitions (demands for payments or supplies) from the states in proportion with their population, or take credit. Congress may not declare war, enter into treaties and alliances, appropriate money, or appoint a commander in chief without nine states assenting. Congress shall keep a journal of proceedings and adjourn for periods not to exceed six months. When Congress is in recess, any of the powers of Congress may be executed by "The committee of the states, or any nine of them", except for those powers of Congress which require nine states in Congress to execute. If Canada [referring to the British Province of Quebec] accedes to this confederation, it will be admitted. No other colony could be admitted without the consent of nine states. Affirms that the Confederation will honor all bills of credit incurred, monies borrowed, and debts contracted by Congress before the existence of the Articles. Declares that the Articles shall be perpetual, and may be altered only with the approval of Congress and the ratification of all the state legislatures. Congress under the Articles Army Under the Articles, Congress had the authority to regulate and fund the Continental Army, but it lacked the power to compel the States to comply with requests for either troops or funding. This left the military vulnerable to inadequate funding, supplies, and even food. Further, although the Articles enabled the states to present a unified front when dealing with the European powers, as a tool to build a centralized war-making government, they were largely a failure; Historian Bruce Chadwick wrote: Phelps wrote: The Continental Congress, before the Articles were approved, had promised soldiers a pension of half pay for life. However Congress had no power to compel the states to fund this obligation, and as the war wound down after the victory at Yorktown the sense of urgency to support the military was no longer a factor. No progress was made in Congress during the winter of 1783–84. General Henry Knox, who would later become the first Secretary of War under the Constitution, blamed the weaknesses of the Articles for the inability of the government to fund the army. The army had long been supportive of a strong union. Knox wrote: As Congress failed to act on the petitions, Knox wrote to Gouverneur Morris, four years before the Philadelphia Convention was convened, "As the present Constitution is so defective, why do not you great men call the people together and tell them so; that is, to have a convention of the States to form a better Constitution." Once the war had been won, the Continental Army was largely disbanded. A very small national force was maintained to man the frontier forts and to protect against Native American attacks. Meanwhile, each of the states had an army (or militia), and 11 of them had navies. The wartime promises of bounties and land grants to be paid for service were not being met. In 1783, George Washington defused the Newburgh conspiracy, but riots by unpaid Pennsylvania veterans forced Congress to leave Philadelphia temporarily. The Congress from time to time during the Revolutionary War requisitioned troops from the states. Any contributions were voluntary, and in the debates of 1788, the Federalists (who supported the proposed new Constitution) claimed that state politicians acted unilaterally, and contributed when the Continental army protected their state's interests. The Anti-Federalists claimed that state politicians understood their duty to the Union and contributed to advance its needs. Dougherty (2009) concludes that generally the States' behavior validated the Federalist analysis. This helps explain why the Articles of Confederation needed reforms. Foreign policy The 1783 Treaty of Paris, which ended hostilities with Great Britain, languished in Congress for several months because too few delegates were present at any one time to constitute a quorum so that it could be ratified. Afterward, the problem only got worse as Congress had no power to enforce attendance. Rarely did more than half of the roughly sixty delegates attend a session of Congress at the time, causing difficulties in raising a quorum. The resulting paralysis embarrassed and frustrated many American nationalists, including George Washington. Many of the most prominent national leaders, such as Washington, John Adams, John Hancock, and Benjamin Franklin, retired from public life, served as foreign delegates, or held office in state governments; and for the general public, local government and self-rule seemed quite satisfactory. This served to exacerbate Congress's impotence. Inherent weaknesses in the confederation's frame of government also frustrated the ability of the government to conduct foreign policy. In 1786, Thomas Jefferson, concerned over the failure of Congress to fund an American naval force to confront the Barbary pirates, wrote in a diplomatic correspondence to James Monroe that, "It will be said there is no money in the treasury. There never will be money in the treasury till the Confederacy shows its teeth." Furthermore, the 1786 Jay–Gardoqui Treaty with Spain also showed weakness in foreign policy. In this treaty, which was never ratified, the United States was to give up rights to use the Mississippi River for 25 years, which would have economically strangled the settlers west of the Appalachian Mountains. Finally, due to the Confederation's military weakness, it could not compel the British army to leave frontier forts which were on American soil — forts which, in 1783, the British promised to leave, but which they delayed leaving pending U.S. implementation of other provisions such as ending action against Loyalists and allowing them to seek compensation. This incomplete British implementation of the Treaty of Paris would later be resolved by the implementation of Jay's Treaty in 1795 after the federal Constitution came into force. Taxation and commerce Under the Articles of Confederation, the central government's power was kept quite limited. The Confederation Congress could make decisions but lacked enforcement powers. Implementation of most decisions, including modifications to the Articles, required unanimous approval of all thirteen state legislatures. Congress was denied any powers of taxation: it could only request money from the states. The states often failed to meet these requests in full, leaving both Congress and the Continental Army chronically short of money. As more money was printed by Congress, the continental dollars depreciated. In 1779, George Washington wrote to John Jay, who was serving as the president of the Continental Congress, "that a wagon load of money will scarcely purchase a wagon load of provisions." Mr. Jay and the Congress responded in May by requesting $45 million from the States. In an appeal to the States to comply, Jay wrote that the taxes were "the price of liberty, the peace, and the safety of yourselves and posterity." He argued that Americans should avoid having it said "that America had no sooner become independent than she became insolvent" or that "her infant glories and growing fame were obscured and tarnished by broken contracts and violated faith." The States did not respond with any of the money requested from them. Congress had also been denied the power to regulate either foreign trade or interstate commerce and, as a result, all of the States maintained control over their own trade policies. The states and the Confederation Congress both incurred large debts during the Revolutionary War, and how to repay those debts became a major issue of debate following the War. Some States paid off their war debts and others did not. Federal assumption of the states' war debts became a major issue in the deliberations of the Constitutional Convention. Accomplishments Nevertheless, the Confederation Congress did take two actions with long-lasting impact. The Land Ordinance of 1785 and Northwest Ordinance created territorial government, set up protocols for the admission of new states and the division of land into useful units, and set aside land in each township for public use. This system represented a sharp break from imperial colonization, as in Europe, and it established the precedent by which the national (later, federal) government would be sovereign and expand westward—as opposed to the existing states doing so under their sovereignty. The Land Ordinance of 1785 established both the general practices of land surveying in the west and northwest and the land ownership provisions used throughout the later westward expansion beyond the Mississippi River. Frontier lands were surveyed into the now-familiar squares of land called the township (36 square miles), the section (one square mile), and the quarter section (160 acres). This system was carried forward to most of the States west of the Mississippi (excluding areas of Texas and California that had already been surveyed and divided up by the Spanish Empire). Then, when the Homestead Act was enacted in 1867, the quarter section became the basic unit of land that was granted to new settler-farmers. The Northwest Ordinance of 1787 noted the agreement of the original states to give up northwestern land claims, organized the Northwest Territory and laid the groundwork for the eventual creation of new states. Although it did not happen under the articles, the land north of the Ohio River and west of the (present) western border of Pennsylvania ceded by Massachusetts, Connecticut, New York, Pennsylvania, and Virginia, eventually became the states of Ohio, Indiana, Illinois, Michigan, and Wisconsin, and the part of Minnesota that is east of the Mississippi River. The Northwest Ordinance of 1787 also made great advances in the abolition of slavery. New states admitted to the union in this territory would never be slave states. No new states were admitted to the Union under the Articles of Confederation. The Articles provided for a blanket acceptance of the Province of Quebec (referred to as "Canada" in the Articles) into the United States if it chose to do so. It did not, and the subsequent Constitution carried no such special provision of admission. Additionally, ordinances to admit Frankland (later modified to Franklin), Kentucky, and Vermont to the Union were considered, but none were approved. Presidents of Congress Under the Articles of Confederation, the presiding officer of Congress—referred to in many official records as President of the United States in Congress Assembled—chaired the Committee of the States when Congress was in recess, and performed other administrative functions. He was not, however, an executive in the way the later President of the United States is a chief executive, since all of the functions he executed were under the direct control of Congress. There were 10 presidents of Congress under the Articles. The first, Samuel Huntington, had been serving as president of the Continental Congress since September 28, 1779. U.S. under the Articles The peace treaty left the United States independent and at peace but with an unsettled governmental structure. The Articles envisioned a permanent confederation but granted to the Congress—the only federal institution—little power to finance itself or to ensure that its resolutions were enforced. There was no president, no executive agencies, no judiciary, and no tax base. The absence of a tax base meant that there was no way to pay off state and national debts from the war years except by requesting money from the states, which seldom arrived. Although historians generally agree that the Articles were too weak to hold the fast-growing nation together, they do give credit to the settlement of the western issue, as the states voluntarily turned over their lands to national control. By 1783, with the end of the British blockade, the new nation was regaining its prosperity. However, trade opportunities were restricted by the mercantilism of the British and French empires. The ports of the British West Indies were closed to all staple products which were not carried in British ships. France and Spain established similar policies. Simultaneously, new manufacturers faced sharp competition from British products which were suddenly available again. Political unrest in several states and efforts by debtors to use popular government to erase their debts increased the anxiety of the political and economic elites which had led the Revolution. The apparent inability of the Congress to redeem the public obligations (debts) incurred during the war, or to become a forum for productive cooperation among the states to encourage commerce and economic development, only aggravated a gloomy situation. In 1786–87, Shays' Rebellion, an uprising of dissidents in western Massachusetts against the state court system, threatened the stability of state government. The Continental Congress printed paper money which was so depreciated that it ceased to pass as currency, spawning the expression "not worth a continental". Congress could not levy taxes and could only make requisitions upon the States. Less than a million and a half dollars came into the treasury between 1781 and 1784, although the governors had been asked for two million in 1783 alone. When John Adams went to London in 1785 as the first representative of the United States, he found it impossible to secure a treaty for unrestricted commerce. Demands were made for favors and there was no assurance that individual states would agree to a treaty. Adams stated it was necessary for the States to confer the power of passing navigation laws to Congress, or that the States themselves pass retaliatory acts against Great Britain. Congress had already requested and failed to get power over navigation laws. Meanwhile, each State acted individually against Great Britain to little effect. When other New England states closed their ports to British shipping, Connecticut hastened to profit by opening its ports. By 1787 Congress was unable to protect manufacturing and shipping. State legislatures were unable or unwilling to resist attacks upon private contracts and public credit. Land speculators expected no rise in values when the government could not defend its borders nor protect its frontier population. The idea of a convention to revise the Articles of Confederation grew in favor. Alexander Hamilton realized while serving as Washington's top aide that a strong central government was necessary to avoid foreign intervention and allay the frustrations due to an ineffectual Congress. Hamilton led a group of like-minded nationalists, won Washington's endorsement, and convened the Annapolis Convention in 1786 to petition Congress to call a constitutional convention to meet in Philadelphia to remedy the long-term crisis. Signatures The Second Continental Congress approved the Articles for distribution to the states on November 15, 1777. A copy was made for each state and one was kept by the Congress. On November 28, the copies sent to the states for ratification were unsigned, and the cover letter, dated November 17, had only the signatures of Henry Laurens and Charles Thomson, who were the President and Secretary to the Congress. The Articles, however, were unsigned, and the date was blank. Congress began the signing process by examining their copy of the Articles on June 27, 1778. They ordered a final copy prepared (the one in the National Archives), and that delegates should inform the secretary of their authority for ratification. On July 9, 1778, the prepared copy was ready. They dated it and began to sign. They also requested each of the remaining states to notify its delegation when ratification was completed. On that date, delegates present from New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, Pennsylvania, Virginia and South Carolina signed the Articles to indicate that their states had ratified. New Jersey, Delaware and Maryland could not, since their states had not ratified. North Carolina and Georgia also were unable to sign that day, since their delegations were absent. After the first signing, some delegates signed at the next meeting they attended. For example, John Wentworth of New Hampshire added his name on August 8. John Penn was the first of North Carolina's delegates to arrive (on July 10), and the delegation signed the Articles on July 21, 1778. The other states had to wait until they ratified the Articles and notified their Congressional delegation. Georgia signed on July 24, New Jersey on November 26, and Delaware on February 12, 1779. Maryland refused to ratify the Articles until every state had ceded its western land claims. Chevalier de La Luzerne, French Minister to the United States, felt that the Articles would help strengthen the American government. In 1780, when Maryland requested France provide naval forces in the Chesapeake Bay for protection from the British (who were conducting raids in the lower part of the bay), he indicated that French Admiral Destouches would do what he could but La Luzerne also "sharply pressed" Maryland to ratify the Articles, thus suggesting the two issues were related. On February 2, 1781, the much-awaited decision was taken by the Maryland General Assembly in Annapolis. As the last piece of business during the afternoon Session, "among engrossed Bills" was "signed and sealed by Governor Thomas Sim Lee in the Senate Chamber, in the presence of the members of both Houses... an Act to empower the delegates of this state in Congress to subscribe and ratify the articles of confederation" and perpetual union among the states. The Senate then adjourned "to the first Monday in August next." The decision of Maryland to ratify the Articles was reported to the Continental Congress on February 12. The confirmation signing of the Articles by the two Maryland delegates took place in Philadelphia at noon time on March 1, 1781, and was celebrated in the afternoon. With these events, the Articles were entered into force and the United States of America came into being as a sovereign federal state. Congress had debated the Articles for over a year and a half, and the ratification process had taken nearly three and a half years. Many participants in the original debates were no longer delegates, and some of the signers had only recently arrived. The Articles of Confederation and Perpetual Union were signed by a group of men who were never present in the Congress at the same time. Signers The signers and the states they represented were: Connecticut Roger Sherman Samuel Huntington Oliver Wolcott Titus Hosmer Andrew Adams Delaware Thomas McKean John Dickinson Nicholas Van Dyke Georgia John Walton Edward Telfair Edward Langworthy Maryland John Hanson Daniel Carroll Massachusetts Bay John Hancock Samuel Adams Elbridge Gerry Francis Dana James Lovell Samuel Holten New Hampshire Josiah Bartlett John Wentworth Jr. New Jersey John Witherspoon Nathaniel Scudder New York James Duane Francis Lewis William Duer Gouverneur Morris North Carolina John Penn Cornelius Harnett John Williams Pennsylvania Robert Morris Daniel Roberdeau Jonathan Bayard Smith William Clingan Joseph Reed Rhode Island and Providence Plantations William Ellery Henry Marchant John Collins South Carolina Henry Laurens William Henry Drayton John Mathews Richard Hutson Thomas Heyward Jr. Virginia Richard Henry Lee John Banister Thomas Adams John Harvie Francis Lightfoot Lee Roger Sherman (Connecticut) was the only person to sign all four great state papers of the United States: the Continental Association, the United States Declaration of Independence, the Articles of Confederation and the United States Constitution. Robert Morris (Pennsylvania) signed three of the great state papers of the United States: the United States Declaration of Independence, the Articles of Confederation and the United States Constitution. John Dickinson (Delaware), Daniel Carroll (Maryland) and Gouverneur Morris (New York), along with Sherman and Robert Morris, were the only five people to sign both the Articles of Confederation and the United States Constitution (Gouverneur Morris represented Pennsylvania when signing the Constitution). Parchment pages Original parchment pages of the Articles of Confederation, National Archives and Records Administration. Revision and replacement In September 1786, delegates from five states met at what became known as the Annapolis Convention to discuss the need for reversing the protectionist interstate trade barriers that each state had erected. At its conclusion, delegates voted to invite all states to a larger convention to be held in Philadelphia in 1787. The Confederation Congress later endorsed this convention "for the sole and express purpose of revising the Articles of Confederation". Although the states' representatives to the Constitutional Convention in Philadelphia were only authorized to amend the Articles, delegates held secret, closed-door sessions and wrote a new constitution. The new frame of government gave much more power to the central government, but characterization of the result is disputed. The general goal of the authors was to get close to a republic as defined by the philosophers of the Age of Enlightenment, while trying to address the many difficulties of the interstate relationships. Historian Forrest McDonald, using the ideas of James Madison from Federalist 39, described the change this way: In May 1786, Charles Pinckney of South Carolina proposed that Congress revise the Articles of Confederation. Recommended changes included granting Congress power over foreign and domestic commerce, and providing means for Congress to collect money from state treasuries. Unanimous approval was necessary to make the alterations, however, and Congress failed to reach a consensus. The weakness of the Articles in establishing an effective unifying government was underscored by the threat of internal conflict both within and between the states, especially after Shays' Rebellion threatened to topple the state government of Massachusetts. Historian Ralph Ketcham commented on the opinions of Patrick Henry, George Mason, and other Anti-Federalists who were not so eager to give up the local autonomy won by the revolution: Historians have given many reasons for the perceived need to replace the articles in 1787. Jillson and Wilson (1994) point to the financial weakness as well as the norms, rules and institutional structures of the Congress, and the propensity to divide along sectional lines. Rakove identifies several factors that explain the collapse of the Confederation. The lack of compulsory direct taxation power was objectionable to those wanting a strong centralized state or expecting to benefit from such power. It could not collect customs after the war because tariffs were vetoed by Rhode Island. Rakove concludes that their failure to implement national measures "stemmed not from a heady sense of independence but rather from the enormous difficulties that all the states encountered in collecting taxes, mustering men, and gathering supplies from a war-weary populace." The second group of factors Rakove identified derived from the substantive nature of the problems the Continental Congress confronted after 1783, especially the inability to create a strong foreign policy. Finally, the Confederation's lack of coercive power reduced the likelihood for profit to be made by political means, thus potential rulers were uninspired to seek power. When the war ended in 1783, certain special interests had incentives to create a new "merchant state," much like the British state people had rebelled against. In particular, holders of war scrip and land speculators wanted a central government to pay off scrip at face value and to legalize western land holdings with disputed claims. Also, manufacturers wanted a high tariff as a barrier to foreign goods, but competition among states made this impossible without a central government. Legitimacy of closing down Two prominent political leaders in the Confederation, John Jay of New York and Thomas Burke of North Carolina believed that "the authority of the congress rested on the prior acts of the several states, to which the states gave their voluntary consent, and until those obligations were fulfilled, neither nullification of the authority of congress, exercising its due powers, nor secession from the compact itself was consistent with the terms of their original pledges." According to Article XIII of the Confederation, any alteration had to be approved unanimously: [T]he Articles of this Confederation shall be inviolably observed by every State, and the Union shall be perpetual; nor shall any alteration at any time hereafter be made in any of them; unless such alteration be agreed to in a Congress of the United States, and be afterwards confirmed by the legislatures of every State. On the other hand, Article VII of the proposed Constitution stated that it would become effective after ratification by a mere nine states, without unanimity: The Ratification of the Conventions of nine States, shall be sufficient for the Establishment of this Constitution between the States so ratifying the Same. The apparent tension between these two provisions was addressed at the time, and remains a topic of scholarly discussion. In 1788, James Madison remarked (in Federalist No. 40) that the issue had become moot: "As this objection… has been in a manner waived by those who have criticised the powers of the convention, I dismiss it without further observation." Nevertheless, it is a historical and legal question whether opponents of the Constitution could have plausibly attacked the Constitution on that ground. At the time, there were state legislators who argued that the Constitution was not an alteration of the Articles of Confederation, but rather would be a complete replacement so the unanimity rule did not apply. Moreover, the Confederation had proven woefully inadequate and therefore was supposedly no longer binding. Modern scholars such as Francisco Forrest Martin agree that the Articles of Confederation had lost its binding force because many states had violated it, and thus "other states-parties did not have to comply with the Articles' unanimous consent rule". In contrast, law professor Akhil Amar suggests that there may not have really been any conflict between the Articles of Confederation and the Constitution on this point; Article VI of the Confederation specifically allowed side deals among states, and the Constitution could be viewed as a side deal until all states ratified it. Final months On July 3, 1788, the Congress received New Hampshire's all-important ninth ratification of the proposed Constitution, thus, according to its terms, establishing it as the new framework of governance for the ratifying states. The following day delegates considered a bill to admit Kentucky into the Union as a sovereign state. The discussion ended with Congress making the determination that, in light of this development, it would be "unadvisable" to admit Kentucky into the Union, as it could do so "under the Articles of Confederation" only, but not "under the Constitution". By the end of July 1788, 11 of the 13 states had ratified the new Constitution. Congress continued to convene under the Articles with a quorum until October. On Saturday, September 13, 1788, the Confederation Congress voted the resolve to implement the new Constitution, and on Monday, September 15 published an announcement that the new Constitution had been ratified by the necessary nine states, set the first Wednesday in January 1789 for appointing electors, set the first Wednesday in February 1789 for the presidential electors to meet and vote for a new president, and set the first Wednesday of March 1789 as the day "for commencing proceedings" under the new Constitution. On that same September 13, it determined that New York would remain the national capital.

Atlantic Ocean

The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe, and Asia from the "New World" of the Americas in the European perception of the World. Through its separation from Africa, Europe, and Asia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the history of many nations. While the Norse were the first humans to cross the Atlantic, it was the 1492 expedition of Christopher Columbus which proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and the Columbian exchange while occasionally hosting naval battles. Such naval battles, as well as growing trade from regional American powers like the United States and Brazil, both increased in degree during the 20th century, and while no major military conflicts took place in the Atlantic in the present 21st century, the ocean remains a core component of trade across the world. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Toponymy The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211): (Greek: ; English: 'the Atlantic sea'; etym. 'Sea of Atlas') and in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): (Greek: ; English: 'Sea of Atlas' or 'the Atlantic sea') where the name refers to "the sea beyond the pillars of Heracles" which is said to be part of the sea that surrounds all land. In these uses, the name refers to Atlas, the Titan in Greek mythology, who supported the heavens and who later appeared as a frontispiece in Medieval maps and also lent his name to modern atlases. On the other hand, to early Greek sailors and in Ancient Greek mythological literature such as the Iliad and the Odyssey, this all-encompassing ocean was instead known as Oceanus, the gigantic river that encircled the world; in contrast to the enclosed seas well known to the Greeks: the Mediterranean and the Black Sea. In contrast, the term "Atlantic" originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of millions of years ago. The term "Aethiopian Ocean", derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century. During the Age of Discovery, the Atlantic was also known to English cartographers as the Great Western Ocean. The pond is a term often used by British and American speakers in reference to the Northern Atlantic Ocean, as a form of meiosis, or ironic understatement. It is used mostly when referring to events or circumstances "on this side of the pond" or "on the other side of the pond", rather than to discuss the ocean itself. The term dates to 1640, first appearing in print in pamphlet released during the reign of Charles I, and reproduced in 1869 in Nehemiah Wallington's Historical Notices of Events Occurring Chiefly in The Reign of Charles I, where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank, Charles I's Secretary of State. Extent and data The International Hydrographic Organization (IHO) defined the limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not used by various authorities, institutions, and countries, see for example the CIA World Factbook. Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea and Barents Sea. To the east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea—one of its marginal seas—and, in turn, the Black Sea, both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean. The Atlantic has irregular coasts indented by numerous bays, gulfs and seas. These include the Baltic Sea, Black Sea, Caribbean Sea, Davis Strait, Denmark Strait, part of the Drake Passage, Gulf of Mexico, Labrador Sea, Mediterranean Sea, North Sea, Norwegian Sea, almost all of the Scotia Sea, and other tributary water bodies. Including these marginal seas the coast line of the Atlantic measures compared to for the Pacific. Including its marginal seas, the Atlantic covers an area of or 23.5% of the global ocean and has a volume of or 23.3% of the total volume of the earth's oceans. Excluding its marginal seas, the Atlantic covers and has a volume of . The North Atlantic covers (11.5%) and the South Atlantic (11.1%). The average depth is and the maximum depth, the Milwaukee Deep in the Puerto Rico Trench, is .

It runs from 87°N or south of the North Pole to the subantarctic Bouvet Island at 54°S. Expeditions to explore the bathymertry of the Atlantic include the Challenger expedition and the German Meteor expedition; presently, Columbia University's Lamont–Doherty Earth Observatory and the United States Navy Hydrographic Office conduct research on the ocean. Mid-Atlantic Ridge The MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above along most of its length, but is interrupted by larger transform faults at two places: the Romanche Trench near the Equator and the Gibbs Fracture Zone at 53°N. The MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other. The MAR rises above the surrounding ocean floor and its rift valley is the divergent boundary between the North American and Eurasian plates in the North Atlantic and the South American and African plates in the South Atlantic. The MAR produces basaltic volcanoes in Eyjafjallajökull, Iceland, and pillow lava on the ocean floor. The depth of water at the apex of the ridge is less than in most places, while the bottom of the ridge is three times as deep. The MAR is intersected by two perpendicular ridges: the Azores–Gibraltar Transform Fault, the boundary between the Nubian and Eurasian plates, intersects the MAR at the Azores Triple Junction, on either side of the Azores microplate, near the 40°N. A much vaguer, nameless boundary, between the North American and South American plates, intersects the MAR near or just north of the Fifteen-Twenty Fracture Zone, approximately at 16°N. In the 1870s, the Challenger expedition discovered parts of what is now known as the Mid-Atlantic Ridge, or: The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment. The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics. Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. While nine of these have collectively been nominated a World Heritage Site for their geological value, four of them are considered of "Outstanding Universal Value" based on their cultural and natural criteria: Þingvellir, Iceland; Landscape of the Pico Island Vineyard Culture, Portugal; Gough and Inaccessible Islands, United Kingdom; and Brazilian Atlantic Islands: Fernando de Noronha and Atol das Rocas Reserves, Brazil. Ocean floor Continental shelves in the Atlantic are wide off Newfoundland, southernmost South America, and north-eastern Europe. In the western Atlantic carbonate platforms dominate large areas, for example, the Blake Plateau and Bermuda Rise. The Atlantic is surrounded by passive margins except at a few locations where active margins form deep trenches: the Puerto Rico Trench ( maximum depth) in the western Atlantic and South Sandwich Trench () in the South Atlantic. There are numerous submarine canyons off north-eastern North America, western Europe, and north-western Africa. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels. In 1922, a historic moment in cartography and oceanography occurred. The USS Stewart used a Navy Sonic Depth Finder to draw a continuous map across the bed of the Atlantic. This involved little guesswork because the idea of sonar is straightforward with pulses being sent from the vessel, which bounce off the ocean floor, then return to the vessel. The deep ocean floor is thought to be fairly flat with occasional deeps, abyssal plains, trenches, seamounts, basins, plateaus, canyons, and some guyots. Various shelves along the margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is , or close to the average for the global ocean, with a modal depth between . In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss is found off the eastern coast of Canada. Water characteristics Surface water temperatures, which vary with latitude, current systems, and season and reflect the latitudinal distribution of solar energy, range from below to over . Maximum temperatures occur north of the equator, and minimum values are found in the polar regions. In the middle latitudes, the area of maximum temperature variations, values may vary by . From October to June the surface is usually covered with sea ice in the Labrador Sea, Denmark Strait, and Baltic Sea. The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur every 24 lunar hours. In latitudes above 40° North some east–west oscillation, known as the North Atlantic oscillation, occurs. Salinity On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values. Although the lowest salinity values are just north of the equator (because of heavy tropical rainfall), in general, the lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south, in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings, which brings salty Indian Ocean waters into the South Atlantic, and the "Atmospheric Bridge", which evaporates subtropical Atlantic waters and exports it to the Pacific. Water masses The Atlantic Ocean consists of four major, upper water masses with distinct temperature and salinity. The Atlantic Subarctic Upper Water in the northernmost North Atlantic is the source for Subarctic Intermediate Water and North Atlantic Intermediate Water. North Atlantic Central Water can be divided into the Eastern and Western North Atlantic central Water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean Water. North Atlantic Central Water flows into South Atlantic Central Water at 15°N. There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic Intermediate Water, flows from north to become the source for North Atlantic Deep Water south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and the large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water. The North Atlantic Deep Water (NADW) is a complex of four water masses, two that form by deep convection in the open ocean — Classical and Upper Labrador Sea Water — and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill — Denmark Strait and Iceland-Scotland Overflow Water. Along its path across Earth the composition of the NADW is affected by other water masses, especially Antarctic Bottom Water and Mediterranean Overflow Water. The NADW is fed by a flow of warm shallow water into the northern North Atlantic which is responsible for the anomalous warm climate in Europe. Changes in the formation of NADW have been linked to global climate changes in the past. Since man-made substances were introduced into the environment, the path of the NADW can be traced throughout its course by measuring tritium and radiocarbon from nuclear weapon tests in the 1960s and CFCs. Gyres The clockwise warm-water North Atlantic Gyre occupies the northern Atlantic, and the counter-clockwise warm-water South Atlantic Gyre appears in the southern Atlantic. In the North Atlantic, surface circulation is dominated by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras; the North Atlantic Current, a branch of the Gulf Stream which flows northward from the Grand Banks; and the Subpolar Front, an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transport warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of the North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate variability. It is governed by ocean currents from marginal seas and regional topography, rather than being steered by wind, both in the deep ocean and at sea level. The subpolar gyre forms an important part of the global thermohaline circulation. Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from the subtropics to the north-eastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv) current which flows around the continental margins of the Labrador Sea. A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in its turn, feeds the meridional overturning circulation (MOC), the northward heat transport of which is threatened by anthropogenic climate change. Large variations in the subpolar gyre on a decade-century scale, associated with the North Atlantic oscillation, are especially pronounced in Labrador Sea Water, the upper layers of the MOC. The South Atlantic is dominated by the anti-cyclonic southern subtropical gyre. The South Atlantic Central Water originates in this gyre, while Antarctic Intermediate Water originates in the upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer. The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below the thermocline of the subtropical gyre. Sargasso Sea The Sargasso Sea in the western North Atlantic can be defined as the area where two species of Sargassum (S. fluitans and natans) float, an area wide and encircled by the Gulf Stream, North Atlantic Drift, and North Equatorial Current. This population of seaweed probably originated from Tertiary ancestors on the European shores of the former Tethys Ocean and has, if so, maintained itself by vegetative growth, floating in the ocean for millions of years. Other species endemic to the Sargasso Sea include the sargassum fish, a predator with algae-like appendages which hovers motionless among the Sargassum. Fossils of similar fishes have been found in fossil bays of the former Tethys Ocean, in what is now the Carpathian region, that were similar to the Sargasso Sea. It is possible that the population in the Sargasso Sea migrated to the Atlantic as the Tethys closed at the end of the Miocene around 17 Ma. The origin of the Sargasso fauna and flora remained enigmatic for centuries. The fossils found in the Carpathians in the mid-20th century often called the "quasi-Sargasso assemblage", finally showed that this assemblage originated in the Carpathian Basin from where it migrated over Sicily to the Central Atlantic where it evolved into modern species of the Sargasso Sea. The location of the spawning ground for European eels remained unknown for decades. In the early 19th century it was discovered that the southern Sargasso Sea is the spawning ground for both the European and American eel and that the former migrate more than and the latter . Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and Northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. Climate Climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of the ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from water temperatures. The oceans are the major source of the atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across the Atlantic north of the equator. The coldest zones are in high latitudes, with the coldest regions corresponding to the areas covered by sea ice. Ocean currents influence the climate by transporting warm and cold waters to other regions. The winds that are cooled or warmed when blowing over these currents influence adjacent land areas. The Gulf Stream and its northern extension towards Europe, the North Atlantic Drift is thought to have at least some influence on climate. For example, the Gulf Stream helps moderate winter temperatures along the coastline of southeastern North America, keeping it warmer in winter along the coast than inland areas. The Gulf Stream also keeps extreme temperatures from occurring on the Florida Peninsula. In the higher latitudes, the North Atlantic Drift, warms the atmosphere over the oceans, keeping the British Isles and north-western Europe mild and cloudy, and not severely cold in winter, like other locations at the same high latitude. The cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks of Newfoundland area) and Africa's north-western coast. In general, winds transport moisture and air over land areas. Natural hazards Every winter, the Icelandic Low produces frequent storms. Icebergs are common from early February to the end of July across the shipping lanes near the Grand Banks of Newfoundland. The ice season is longer in the polar regions, but there is little shipping in those areas. Hurricanes are a hazard in the western parts of the North Atlantic during the summer and autumn. Due to a consistently strong wind shear and a weak Intertropical Convergence Zone, South Atlantic tropical cyclones are rare. Geology and plate tectonics The Atlantic Ocean is underlain mostly by dense mafic oceanic crust made up of basalt and gabbro and overlain by fine clay, silt and siliceous ooze on the abyssal plain. The continental margins and continental shelf mark lower density, but greater thickness felsic continental rock that is often much older than that of the seafloor. The oldest oceanic crust in the Atlantic is up to 145 million years and situated off the west coast of Africa and east coast of North America, or on either side of the South Atlantic. In many places, the continental shelf and continental slope are covered in thick sedimentary layers. For instance, on the North American side of the ocean, large carbonate deposits formed in warm shallow waters such as Florida and the Bahamas, while coarse river outwash sands and silt are common in shallow shelf areas like the Georges Bank. Coarse sand, boulders, and rocks were transported into some areas, such as off the coast of Nova Scotia or the Gulf of Maine during the Pleistocene ice ages. Central Atlantic The break-up of Pangaea began in the Central Atlantic, between North America and Northwest Africa, where rift basins opened during the Late Triassic and Early Jurassic. This period also saw the first stages of the uplift of the Atlas Mountains. The exact timing is controversial with estimates ranging from 200 to 170 Ma. The opening of the Atlantic Ocean coincided with the initial break-up of the supercontinent Pangaea, both of which were initiated by the eruption of the Central Atlantic Magmatic Province (CAMP), one of the most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event, one of Earth's major extinction events. Theoliitic dikes, sills, and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America. The extent of the volcanism has been estimated to of which covered what is now northern and central Brazil. The formation of the Central American Isthmus closed the Central American Seaway at the end of the Pliocene 2.8 Ma ago. The formation of the isthmus resulted in the migration and extinction of many land-living animals, known as the Great American Interchange, but the closure of the seaway resulted in a "Great American Schism" as it affected ocean currents, salinity, and temperatures in both the Atlantic and Pacific. Marine organisms on both sides of the isthmus became isolated and either diverged or went extinct. Geologically, the Northern Atlantic is the area delimited to the south by two conjugate margins, Newfoundland and Iberia, and to the north by the Arctic Eurasian Basin. The opening of the Northern Atlantic closely followed the margins of its predecessor, the Iapetus Ocean, and spread from the Central Atlantic in six stages: Iberia–Newfoundland, Porcupine–North America, Eurasia–Greenland, Eurasia–North America. Active and inactive spreading systems in this area are marked by the interaction with the Iceland hotspot. Seafloor spreading led to the extension of the crust and formations of troughs and sedimentary basins. The Rockall Trough opened between 105 and 84 million years ago although along the rift failed along with one leading into the Bay of Biscay. Spreading began opening the Labrador Sea around 61 million years ago, continuing until 36 million years ago. Geologists distinguish two magmatic phases. One from 62 to 58 million years ago predates the separation of Greenland from northern Europe while the second from 56 to 52 million years ago happened as the separation occurred. Iceland began to form 62 million years ago due to a particularly concentrated mantle plume. Large quantities of basalt erupted at this time period are found on Baffin Island, Greenland, the Faroe Islands, and Scotland, with ash falls in Western Europe acting as a stratigraphic marker. The opening of the North Atlantic caused significant uplift of continental crust along the coast. For instance, in spite of 7 km thick basalt, Gunnbjorn Field in East Greenland is the highest point on the island, elevated enough that it exposes older Mesozoic sedimentary rocks at its base, similar to old lava fields above sedimentary rocks in the uplifted Hebrides of western Scotland. The North Atlantic Ocean contains about 810 seamounts, most of them situated along the Mid-Atlantic Ridge. The OSPAR database (Convention for the Protection of the Marine Environment of the North-East Atlantic) mentions 104 seamounts: 74 within the national Exclusive economic zone. Of these seamounts, 46 are located close to the Iberian Peninsula. South Atlantic West Gondwana (South America and Africa) broke up in the Early Cretaceous to form the South Atlantic. The apparent fit between the coastlines of the two continents was noted on the first maps that included the South Atlantic and it was also the subject of the first computer-assisted plate tectonic reconstructions in 1965. This magnificent fit, however, has since then proven problematic and later reconstructions have introduced various deformation zones along the shorelines to accommodate the northward-propagating break-up. Intra-continental rifts and deformations have also been introduced to subdivide both continental plates into sub-plates. Geologically the South Atlantic can be divided into four segments: Equatorial segment, from 10°N to the Romanche Fracture Zone (RFZ); Central segment, from RFZ to Florianopolis Fracture Zone (FFZ, north of Walvis Ridge and Rio Grande Rise); Southern segment, from FFZ to the Agulhas-Falkland Fracture Zone (AFFZ); and Falkland segment, south of AFFZ. In the southern segment the Early Cretaceous (133–130 Ma) intensive magmatism of the Paraná–Etendeka Large Igneous Province produced by the Tristan hotspot resulted in an estimated volume of . It covered an area of in Brazil, Paraguay, and Uruguay and in Africa. Dyke swarms in Brazil, Angola, eastern Paraguay, and Namibia, however, suggest the LIP originally covered a much larger area and also indicate failed rifts in all these areas. Associated offshore basaltic flows reach as far south as the Falkland Islands and South Africa. Traces of magmatism in both offshore and onshore basins in the central and southern segments have been dated to 147–49 Ma with two peaks between 143 and 121 Ma and 90–60 Ma. In the Falkland segment rifting began with dextral movements between the Patagonia and Colorado sub-plates between the Early Jurassic (190 Ma) and the Early Cretaceous (126.7 Ma). Around 150 Ma sea-floor spreading propagated northward into the southern segment. No later than 130 Ma rifting had reached the Walvis Ridge–Rio Grande Rise. In the central segment rifting started to break Africa in two by opening the Benue Trough around 118 Ma. Rifting in the central segment, however, coincided with the Cretaceous Normal Superchron (also known as the Cretaceous quiet period), a 40 Ma period without magnetic reversals, which makes it difficult to date sea-floor spreading in this segment. The equatorial segment is the last phase of the break-up, but, because it is located on the Equator, magnetic anomalies cannot be used for dating. Various estimates date the propagation of sea-floor spreading in this segment and consequent opening of the Equatorial Atlantic Gateway (EAG) to the period 120–96 Ma. This final stage, nevertheless, coincided with or resulted in the end of continental extension in Africa. About 50 Ma the opening of the Drake Passage resulted from a change in the motions and separation rate of the South American and Antarctic plates. First small ocean basins opened and a shallow gateway appeared during the Middle Eocene. 34–30 Ma a deeper seaway developed, followed by an Eocene–Oligocene climatic deterioration and the growth of the Antarctic ice sheet. Closure of the Atlantic An embryonic subduction margin is potentially developing west of Gibraltar. The Gibraltar Arc in the western Mediterranean is migrating westward into the Central Atlantic where it joins the converging African and Eurasian plates. Together these three tectonic forces are slowly developing into a new subduction system in the eastern Atlantic Basin. Meanwhile, the Scotia Arc and Caribbean Plate in the western Atlantic Basin are eastward-propagating subduction systems that might, together with the Gibraltar system, represent the beginning of the closure of the Atlantic Ocean and the final stage of the Atlantic Wilson cycle. History Human origin Humans evolved in Africa; first by diverging from other apes around 7 mya; then developing stone tools around 2.6 mya; to finally evolve as modern humans around 200 kya. The earliest evidence for the complex behavior associated with this behavioral modernity has been found in the Greater Cape Floristic Region (GCFR) along the coast of South Africa. During the latest glacial stages, the now-submerged plains of the Agulhas Bank were exposed above sea level, extending the South African coastline farther south by hundreds of kilometers. A small population of modern humans — probably fewer than a thousand reproducing individuals — survived glacial maxima by exploring the high diversity offered by these Palaeo-Agulhas plains. The GCFR is delimited to the north by the Cape Fold Belt and the limited space south of it resulted in the development of social networks out of which complex Stone Age technologies emerged. Human history thus begins on the coasts of South Africa where the Atlantic Benguela Upwelling and Indian Ocean Agulhas Current meet to produce an intertidal zone on which shellfish, fur seal, fish and sea birds provided the necessary protein sources. The African origin of this modern behaviour is evidenced by 70,000 years-old engravings from Blombos Cave, South Africa. Old World Mitochondrial DNA (mtDNA) studies indicate that 80–60,000 years ago a major demographic expansion within Africa, derived from a single, small population, coincided with the emergence of behavioral complexity and the rapid MIS 5–4 environmental changes. This group of people not only expanded over the whole of Africa, but also started to disperse out of Africa into Asia, Europe, and Australasia around 65,000 years ago and quickly replaced the archaic humans in these regions. During the Last Glacial Maximum (LGM) 20,000 years ago humans had to abandon their initial settlements along the European North Atlantic coast and retreat to the Mediterranean. Following rapid climate changes at the end of the LGM this region was repopulated by Magdalenian culture. Other hunter-gatherers followed in waves interrupted by large-scale hazards such as the Laacher See volcanic eruption, the inundation of Doggerland (now the North Sea), and the formation of the Baltic Sea. The European coasts of the North Atlantic were permanently populated about 9–8.5 thousand years ago. This human dispersal left abundant traces along the coasts of the Atlantic Ocean. 50 kya-old, deeply stratified shell middens found in Ysterfontein on the western coast of South Africa are associated with the Middle Stone Age (MSA). The MSA population was small and dispersed and the rate of their reproduction and exploitation was less intense than those of later generations. While their middens resemble 12–11 kya-old Late Stone Age (LSA) middens found on every inhabited continent, the 50–45 kya-old Enkapune Ya Muto in Kenya probably represents the oldest traces of the first modern humans to disperse out of Africa. The same development can be seen in Europe. In La Riera Cave (23–13 kya) in Asturias, Spain, only some 26,600 molluscs were deposited over 10 kya. In contrast, 8–7 kya-old shell middens in Portugal, Denmark, and Brazil generated thousands of tons of debris and artefacts. The Ertebølle middens in Denmark, for example, accumulated of shell deposits representing some 50 million molluscs over only a thousand years. This intensification in the exploitation of marine resources has been described as accompanied by new technologies — such as boats, harpoons, and fish-hooks — because many caves found in the Mediterranean and on the European Atlantic coast have increased quantities of marine shells in their upper levels and reduced quantities in their lower. The earliest exploitation, however, took place on the now submerged shelves, and most settlements now excavated were then located several kilometers from these shelves. The reduced quantities of shells in the lower levels can represent the few shells that were exported inland. New World During the LGM the Laurentide Ice Sheet covered most of northern North America while Beringia connected Siberia to Alaska. In 1973, late American geoscientist Paul S. Martin proposed a "blitzkrieg" colonization of the Americas by which Clovis hunters migrated into North America around 13,000 years ago in a single wave through an ice-free corridor in the ice sheet and "spread southward explosively, briefly attaining a density sufficiently large to overkill much of their prey." Others later proposed a "three-wave" migration over the Bering Land Bridge. These hypotheses remained the long-held view regarding the settlement of the Americas, a view challenged by more recent archaeological discoveries: the oldest archaeological sites in the Americas have been found in South America; sites in north-east Siberia report virtually no human presence there during the LGM; and most Clovis artefacts have been found in eastern North America along the Atlantic coast. Furthermore, colonisation models based on mtDNA, yDNA, and atDNA data respectively support neither the "blitzkrieg" nor the "three-wave" hypotheses but they also deliver mutually ambiguous results. Contradictory data from archaeology and genetics will most likely deliver future hypotheses that will, eventually, confirm each other. A proposed route across the Pacific to South America could explain early South American finds and another hypothesis proposes a northern path, through the Canadian Arctic and down the North American Atlantic coast. Early settlements across the Atlantic have been suggested by alternative theories, ranging from purely hypothetical to mostly disputed, including the Solutrean hypothesis and some of the Pre-Columbian trans-oceanic contact theories. The Norse settlement of the Faroe Islands and Iceland began during the 9th and 10th centuries. A settlement on Greenland was established before 1000 CE, but contact with it was lost in 1409 and it was finally abandoned during the early Little Ice Age. This setback was caused by a range of factors: an unsustainable economy resulted in erosion and denudation, while conflicts with the local Inuit resulted in the failure to adapt their Arctic technologies; a colder climate resulted in starvation, and the colony got economically marginalized as the Great Plague and Barbary pirates harvested its victims on Iceland in the 15th century. Iceland was initially settled 865–930 CE following a warm period when winter temperatures hovered around which made farming favorable at high latitudes. This did not last, however, and temperatures quickly dropped; at 1080 CE summer temperatures had reached a maximum of . The Landnámabók (Book of Settlement) records disastrous famines during the first century of settlement — "men ate foxes and ravens" and "the old and helpless were killed and thrown over cliffs" — and by the early 1200s hay had to be abandoned for short-season crops such as barley. Atlantic World Christopher Columbus reached the Americas in 1492 under Spanish flag. Six years later Vasco da Gama reached India under the Portuguese flag, by navigating south around the Cape of Good Hope, thus proving that the Atlantic and Indian Oceans are connected. In 1500, in his voyage to India following Vasco da Gama, Pedro Alvares Cabral reached Brazil, taken by the currents of the South Atlantic Gyre. Following these explorations, Spain and Portugal quickly conquered and colonized large territories in the New World and forced the Amerindian population into slavery in order to exploit the vast quantities of silver and gold they found. Spain and Portugal monopolized this trade in order to keep other European nations out, but conflicting interests nevertheless led to a series of Spanish-Portuguese wars. A peace treaty mediated by the Pope divided the conquered territories into Spanish and Portuguese sectors while keeping other colonial powers away. England, France, and the Dutch Republic enviously watched the Spanish and Portuguese wealth grow and allied themselves with pirates such as Henry Mainwaring and Alexandre Exquemelin. They could explore the convoys leaving the Americas because prevailing winds and currents made the transport of heavy metals slow and predictable. In the colonies of the Americas, depredation, smallpox and others diseases, and slavery quickly reduced the indigenous population of the Americas to the extent that the Atlantic slave trade had to be introduced to replace them — a trade that became the norm and an integral part of the colonization. Between the 15th century and 1888, when Brazil became the last part of the Americas to end the slave trade, an estimated ten million Africans were exported as slaves, most of them destined for agricultural labour. The slave trade was officially abolished in the British Empire and the United States in 1808, and slavery itself was abolished in the British Empire in 1838 and in the United States in 1865 after the Civil War. From Columbus to the Industrial Revolution Trans-Atlantic trade, including colonialism and slavery, became crucial for Western Europe. For European countries with direct access to the Atlantic (including Britain, France, the Netherlands, Portugal, and Spain) 1500–1800 was a period of sustained growth during which these countries grew richer than those in Eastern Europe and Asia. Colonialism evolved as part of the Trans-Atlantic trade, but this trade also strengthened the position of merchant groups at the expense of monarchs. Growth was more rapid in non-absolutist countries, such as Britain and the Netherlands, and more limited in absolutist monarchies, such as Portugal, Spain, and France, where profit mostly or exclusively benefited the monarchy and its allies. Trans-Atlantic trade also resulted in increasing urbanization: in European countries facing the Atlantic, urbanization grew from 8% in 1300, 10.1% in 1500, to 24.5% in 1850; in other European countries from 10% in 1300, 11.4% in 1500, to 17% in 1850. Likewise, GDP doubled in Atlantic countries but rose by only 30% in the rest of Europe. By end of the 17th century, the volume of the Trans-Atlantic trade had surpassed that of the Mediterranean trade. The Atlantic Ocean became the scene of one of the longest continuous naval military camapaigns throughout World War II, from 1939 to 1945. Economy The Atlantic has contributed significantly to the development and economy of surrounding countries. Besides major transatlantic transportation and communication routes, the Atlantic offers abundant petroleum deposits in the sedimentary rocks of the continental shelves. The Atlantic harbors petroleum and gas fields, fish, marine mammals (seals and whales), sand and gravel aggregates, placer deposits, polymetallic nodules, and precious stones. Gold deposits are a mile or two under water on the ocean floor, however, the deposits are also encased in rock that must be mined through. Currently, there is no cost-effective way to mine or extract gold from the ocean to make a profit. Various international treaties attempt to reduce pollution caused by environmental threats such as oil spills, marine debris, and the incineration of toxic wastes at sea. Fisheries The shelves of the Atlantic hosts one of the world's richest fishing resources. The most productive areas include the Grand Banks of Newfoundland, the Scotian Shelf, Georges Bank off Cape Cod, the Bahama Banks, the waters around Iceland, the Irish Sea, the Bay of Fundy, the Dogger Bank of the North Sea, and the Falkland Banks. Fisheries have, however, undergone significant changes since the 1950s and global catches can now be divided into three groups of which only two are observed in the Atlantic: fisheries in the Eastern Central and South-West Atlantic oscillate around a globally stable value, the rest of the Atlantic is in overall decline following historical peaks. The third group, "continuously increasing trend since 1950", is only found in the Indian Ocean and Western Pacific. UN FAO partitioned Atlantic in major fishing areas: North-East Atlantic North-East Atlantic is schematically limited to the 42°00' west longitude except around Greenland and at south to 36°00' north latitude; and 68°30' east longitude at the east, according to FAO fisheries definition and include various seas and/or subareas: Barents Sea, Norwegian Sea, Spitzbergen, Bear Island, Skagerrak, Kattegat, Sound, Belt Sea, Baltic Sea, North Sea, Iceland, Faroes Grounds, Rockall, Northwest Coast of Scotland, North Ireland, Irish Sea, West of Ireland, Porcupine Bank, Eastern and Western English Channel, Bay of Biscay, Portuguese Waters, Azores Grounds and Northeast Atlantic South. In the North-East Atlantic total catches decreased between the mid-1970s and the 1990s and reached 8.7 million tons in 2013. Blue whiting reached a 2.4 million tons peak in 2004 but was down to 628,000 tons in 2013. Recovery plans for cod, sole, and plaice have reduced mortality in these species. Arctic cod reached its lowest levels in the 1960s–1980s but is now recovered. Arctic saithe and haddock are considered fully fished; Sand eel is overfished as was capelin which has now recovered to fully fished. Limited data makes the state of redfishes and deep-water species difficult to assess but most likely they remain vulnerable to overfishing. Stocks of northern shrimp and Norwegian lobster are in good condition. In the North-East Atlantic 21% of stocks are considered overfished. This zone makes almost three quarters (72.8 %) of European Union fishing catches in 2020. Main fishing EU countries are Denmark, France, the Netherlands and Spain. Most common species include herring, mackerel and sprats. North-West Atlantic In the North-West Atlantic landings have decreased from 4.2 million tons in the early 1970s to 1.9 million tons in 2013. During the 21st century some species have shown weak signs of recovery, including Greenland halibut, yellowtail flounder, Atlantic halibut, haddock, spiny dogfish, while other stocks shown no such signs, including cod, witch flounder, and redfish. Stocks of invertebrates, in contrast, remain at record levels of abundance. 31% of stocks are overfished in the North-west Atlantic. In 1497, John Cabot became the first Western European since the Vikings to explore mainland North America and one of his major discoveries was the abundant resources of Atlantic cod off Newfoundland. Referred to as "Newfoundland Currency" this discovery yielded some 200 million tons of fish over five centuries. In the late 19th and early 20th centuries new fisheries started to exploit haddock, mackerel, and lobster. From the 1950s to the 1970s the introduction of European and Asian distant-water fleets in the area dramatically increased the fishing capacity and the number of exploited species. It also expanded the exploited areas from near-shore to the open sea and to great depths to include deep-water species such as redfish, Greenland halibut, witch flounder, and grenadiers. Overfishing in the area was recognised as early as the 1960s but, because this was occurring on international waters, it took until the late 1970s before any attempts to regulate was made. In the early 1990s, this finally resulted in the collapse of the Atlantic northwest cod fishery. The population of a number of deep-sea fishes also collapsed in the process, including American plaice, redfish, and Greenland halibut, together with flounder and grenadier. Eastern Central Atlantic In the Eastern Central Atlantic small pelagic fishes constitute about 50% of landings with sardine reaching 0.6–1.0 million tons per year. Pelagic fish stocks are considered fully fished or overfished, with sardines south of Cape Bojador the notable exception. Almost half of the stocks are fished at biologically unsustainable levels. Total catches have been fluctuating since the 1970s; reaching 3.9 million tons in 2013 or slightly less than the peak production in 2010. Western Central Atlantic In the Western Central Atlantic, catches have been decreasing since 2000 and reached 1.3 million tons in 2013. The most important species in the area, Gulf menhaden, reached a million tons in the mid-1980s but only half a million tons in 2013 and is now considered fully fished. Round sardinella was an important species in the 1990s but is now considered overfished. Groupers and snappers are overfished and northern brown shrimp and American cupped oyster are considered fully fished approaching overfished. 44% of stocks are being fished at unsustainable levels. South-East Atlantic In the South-East Atlantic catches have decreased from 3.3 million tons in the early 1970s to 1.3 million tons in 2013. Horse mackerel and hake are the most important species, together representing almost half of the landings. Off South Africa and Namibia deep-water hake and shallow-water Cape hake have recovered to sustainable levels since regulations were introduced in 2006 and the states of Southern African pilchard and anchovy have improved to fully fished in 2013. South-West Atlantic In the South-West Atlantic, a peak was reached in the mid-1980s and catches now fluctuate between 1.7 and 2.6 million tons. The most important species, the Argentine shortfin squid, which reached half a million tons in 2013 or half the peak value, is considered fully fished to overfished. Another important species was the Brazilian sardinella, with a production of 100,000 tons in 2013 it is now considered overfished. Half the stocks in this area are being fished at unsustainable levels: Whitehead's round herring has not yet reached fully fished but Cunene horse mackerel is overfished. The sea snail perlemoen abalone is targeted by illegal fishing and remain overfished. Environmental issues Endangered species Endangered marine species include the manatee, seals, sea lions, turtles, and whales. Drift net fishing can kill dolphins, albatrosses and other seabirds (petrels, auks), hastening the fish stock decline and contributing to international disputes. Waste and pollution Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone. Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. The North Atlantic garbage patch is estimated to be hundreds of kilometers across in size. Other pollution concerns include agricultural and municipal waste. Municipal pollution comes from the eastern United States, southern Brazil, and eastern Argentina; oil pollution in the Caribbean Sea, Gulf of Mexico, Lake Maracaibo, Mediterranean Sea, and North Sea; and industrial waste and municipal sewage pollution in the Baltic Sea, North Sea, and Mediterranean Sea. A USAF C-124 aircraft from Dover Air Force Base, Delaware was carrying three nuclear bombs over the Atlantic Ocean when it experienced a loss of power. For their own safety, the crew jettisoned two nuclear bombs, which were never recovered. Climate change North Atlantic hurricane activity has increased over past decades because of increased sea surface temperature (SST) at tropical latitudes, changes that can be attributed to either the natural Atlantic Multidecadal Oscillation (AMO) or to anthropogenic climate change. A 2005 report indicated that the Atlantic meridional overturning circulation (AMOC) slowed down by 30% between 1957 and 2004. If the AMO were responsible for SST variability, the AMOC would have increased in strength, which is apparently not the case. Furthermore, it is clear from statistical analyses of annual tropical cyclones that these changes do not display multidecadal cyclicity. Therefore, these changes in SST must be caused by human activities. The ocean mixed layer plays an important role in heat storage over seasonal and decadal time-scales, whereas deeper layers are affected over millennia and have a heat capacity about 50 times that of the mixed layer. This heat uptake provides a time-lag for climate change but it also results in thermal expansion of the oceans which contributes to sea level rise. 21st-century global warming will probably result in an equilibrium sea-level rise five times greater than today, whilst melting of glaciers, including that of the Greenland ice-sheet, expected to have virtually no effect during the 21st century, will probably result in a sea-level rise of 3–6 m over a millennium.

Politics of Angola

The current political regime in Angola is presidentialism, in which the President of the Republic is also head of state and government; it is advised by a Council of Ministers, which together with the President form the national executive power. Legislative power rests with the 220 parliamentarians elected to the National Assembly. The President of the Republic, together with the parliament, appoints the majority of the members of the two highest bodies of the judiciary, that is, the Constitutional Court and the Supreme Court. The judiciary is still made up of the Court of Auditors and the Supreme Military Court. The Angolan government is composed of three branches of government: executive, legislative and judicial. For decades, political power has been concentrated in the presidency with the People's Movement for the Liberation of Angola. History Since the adoption of a new constitution in 2010, the politics of Angola takes place in a framework of a presidential republic, whereby the President of Angola is both head of state and head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in the President, the government and parliament. Angola changed from a one-party Marxist-Leninist system ruled by the Popular Movement for the Liberation of Angola (MPLA), in place since independence in 1975, to a multiparty democracy based on a new constitution adopted in 1992. That same year the first parliamentary and presidential elections were held. The MPLA won an absolute majority in the parliamentary elections. In the presidential elections, President José Eduardo dos Santos won the first round election with more than 49% of the vote to Jonas Savimbi's 40%. A runoff election would have been necessary, but never took place. The renewal of civil war immediately after the elections, which were considered as fraudulent by UNITA, and the collapse of the Lusaka Protocol, created a split situation. To a certain degree the new democratic institutions worked, notably the National Assembly, with the active participation of UNITA's and the FNLA's elected MPs - while José Eduardo dos Santos continued to exercise his functions without democratic legitimation. However the armed forces of the MPLA (now the official armed forces of the Angolan state) and of UNITA fought each other until the leader of UNITA, Jonas Savimbi, was killed in action in 2002. From 2002 to 2010, the system as defined by the constitution of 1992 functioned in a relatively normal way. The executive branch of the government was composed of the President, the Prime Minister and Council of Ministers. The Council of Ministers, composed of all ministers and vice ministers, met regularly to discuss policy issues. Governors of the 18 provinces were appointed by and served at the pleasure of the president. The Constitutional Law of 1992 established the broad outlines of government structure and the rights and duties of citizens. The legal system was based on Portuguese and customary law but was weak and fragmented. Courts operated in only 12 of more than 140 municipalities. A Supreme Court served as the appellate tribunal; a Constitutional Court with powers of judicial review was never constituted despite statutory authorization. In practice, power was more and more concentrated in the hands of the President who, supported by an ever-increasing staff, largely controlled parliament, government, and the judiciary. The 26-year-long civil war has ravaged the country's political and social institutions. The UN estimates of 1.8 million internally displaced persons (IDPs), while generally the accepted figure for war-affected people is 4 million. Daily conditions of life throughout the country and specifically Luanda (population approximately 6 million) mirror the collapse of administrative infrastructure as well as many social institutions. The ongoing grave economic situation largely prevents any government support for social institutions. Hospitals are without medicines or basic equipment, schools are without books, and public employees often lack the basic supplies for their day-to-day work. José Eduardo dos Santos stepped down as President of Angola after 38 years in 2017, being peacefully succeeded by João Lourenço, Santos' chosen successor. However, President João Lourenço started a campaign against corruption of the dos Santos era. In November 2017, Isabel dos Santos, the billionaire daughter of former President José Eduardo dos Santos, was fired from her position as head of the country's state oil company Sonangol. In August 2020, José Filomeno dos Santos, son of Angola's former president, was sentenced for five years in jail for fraud and corruption. In August 2022, the ruling party, MPLA, won another outright majority and President Joao Lourenco won a second five-year term in the election. However, the election was the tightest in Angola’s history. Executive branch The 2010 constitution grants the President almost absolute power. Elections for the National assembly are to take place every five years, and the President is automatically the leader of the winning party or coalition. It is for the President to appoint (and dismiss) all of the following: The members of the government (state ministers, ministers, state secretaries and vice-ministers); The members of the Constitutional Court; The members of the Supreme Court; The members of the Court of Auditors; The members of the Military Supreme Court; The Governor and Vice-Governors of the National Angolan Bank; The General-Attorney, the Vice-General-Attorneys and their deputies (as well as the military homologous); The Governors of the provinces; The members of the Republic Council; The members of the National Security Council; The members of the Superior Magistrates Councils; The General Chief of the Armed Forces and his deputy; All other command posts in the military; The Police General Commander, and the 2nd in command; All other command posts in the police; The chiefs and directors of the intelligence and security organs. The President is also provided a variety of powers, like defining the policy of the country. Even though it's not up to him/her to make laws (only to promulgate them and make edicts), the President is the leader of the winning party. The only "relevant" post that is not directly appointed by the President is the Vice-President, which is the second in the winning party. José Eduardo dos Santos stepped down as President of Angola after 38 years in 2017, being peacefully succeeded by João Lourenço, Santos' chosen successor. Legislative branch The National Assembly (Assembleia Nacional) has 223 members, elected for a four-year term, 130 members by proportional representation, 90 members in provincial districts, and 3 members to represent Angolans abroad. The general elections in 1997 were rescheduled for 5 September 2008. The ruling party MPLA won 82% (191 seats in the National Assembly) and the main opposition party won only 10% (16 seats). The elections however have been described as only partly free but certainly not fair. A White Book on the elections in 2008 lists up all irregularities surrounding the Parliamentary elections of 2008. Political parties and elections Judicial branch Supreme Court (or "Tribunal da Relacao") judges of the Supreme Court are appointed by the president. The Constitutional Court, with the power of judicial review, contains 11 justices. Four are appointed by the President, four by the National Assembly, two by the Superior Council of the Judiciary, and one elected by the public.

https://en.wikipedia.org/wiki/Actinopterygii

Actinopterygii

Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from Paedocypris, at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopterygii (~99%) are teleosts. Characteristics Ray-finned fishes occur in many variant forms. The main features of typical ray-finned fish are shown in the adjacent diagram. The swim bladder is the more derived structure. Ray-finned fishes have many different types of scales; but all teleosts have leptoid scales. The outer part of these scales fan out with bony ridges, while the inner part is crossed with fibrous connective tissue. Leptoid scales are thinner and more transparent than other types of scales, and lack the hardened enamel or dentine-like layers found in the scales of many other fish. Unlike ganoid scales, which are found in non-teleost actinopterygians, new scales are added in concentric layers as the fish grows. Ray-finned and lobe-finned fishes sometimes possesses lungs used for aerial respiration. Only bichirs retain ventrally budding lungs. Body shapes and fin arrangements Ray-finned fish vary in size and shape, in their feeding specializations, and in the number and arrangement of their ray-fins. Reproduction In nearly all ray-finned fish, the sexes are separate, and in most species the females spawn eggs that are fertilized externally, typically with the male inseminating the eggs after they are laid. Development then proceeds with a free-swimming larval stage. However other patterns of ontogeny exist, with one of the commonest being sequential hermaphroditism. In most cases this involves protogyny, fish starting life as females and converting to males at some stage, triggered by some internal or external factor. Protandry, where a fish converts from male to female, is much less common than protogyny. Most families use external rather than internal fertilization. Of the oviparous teleosts, most (79%) do not provide parental care. Viviparity, ovoviviparity, or some form of parental care for eggs, whether by the male, the female, or both parents is seen in a significant fraction (21%) of the 422 teleost families; no care is likely the ancestral condition. The oldest case of viviparity in ray-finned fish is found in Middle Triassic species of Saurichthys. Viviparity is relatively rare and is found in about 6% of living teleost species; male care is far more common than female care. Male territoriality "preadapts" a species for evolving male parental care. There are a few examples of fish that self-fertilise. The mangrove rivulus is an amphibious, simultaneous hermaphrodite, producing both eggs and spawn and having internal fertilisation. This mode of reproduction may be related to the fish's habit of spending long periods out of water in the mangrove forests it inhabits. Males are occasionally produced at temperatures below and can fertilise eggs that are then spawned by the female. This maintains genetic variability in a species that is otherwise highly inbred. Classification and fossil record Actinopterygii is divided into the classes Cladistia and Actinopteri. The latter comprises the subclasses Chondrostei and Neopterygii. The Neopterygii, in turn, is divided into the infraclasses Holostei and Teleostei. During the Mesozoic (Triassic, Jurassic, Cretaceous) and Cenozoic the teleosts in particular diversified widely. As a result, 96% of living fish species are teleosts (40% of all fish species belong to the teleost subgroup Acanthomorpha), while all other groups of actinopterygians represent depauperate lineages. The classification of ray-finned fishes can be summarized as follows: Cladistia, which include bichirs and reedfish Actinopteri, which include: Chondrostei, which include Acipenseriformes (paddlefishes and sturgeons) Neopterygii, which include: Teleostei (most living fishes) Holostei, which include: Lepisosteiformes (gars) Amiiformes (bowfin) The cladogram below shows the main clades of living actinopterygians and their evolutionary relationships to other extant groups of fishes and the four-limbed vertebrates (tetrapods). The latter include mostly terrestrial species but also groups that became secondarily aquatic (e.g. Whales and Dolphins). Tetrapods evolved from a group of bony fish during the Devonian period. Approximate divergence dates for the different actinopterygian clades (in millions of years, mya) are from Near et al., 2012. The polypterids (bichirs and reedfish) are the sister lineage of all other actinopterygians, the Acipenseriformes (sturgeons and paddlefishes) are the sister lineage of Neopterygii, and Holostei (bowfin and gars) are the sister lineage of teleosts. The Elopomorpha (eels and tarpons) appear to be the most basal teleosts. The earliest known fossil actinopterygian is Andreolepis hedei, dating back 420 million years (Late Silurian), remains of which have been found in Russia, Sweden, and Estonia. Crown group actinopterygians most likely originated near the Devonian-Carboniferous boundary. The earliest fossil relatives of modern teleosts are from the Triassic period (Prohalecites, Pholidophorus), although it is suspected that teleosts originated already during the Paleozoic Era. Taxonomy The listing below is a summary of all extinct (indicated by a dagger, †) and living groups of Actinopterygii with their respective taxonomic rank. The taxonomy follows Phylogenetic Classification of Bony Fishes with notes when this differs from Nelson, ITIS and FishBase and extinct groups from Van der Laan 2016 and Xu 2021.

Azerbaijan

Azerbaijan (, ; ), officially the Republic of Azerbaijan, is a transcontinental country located at the boundary of Eastern Europe and Western Asia. It is a part of the South Caucasus region and is bounded by the Caspian Sea to the east, Russia (Republic of Dagestan) to the north, Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city. The Azerbaijan Democratic Republic proclaimed its independence from the Transcaucasian Democratic Federative Republic in 1918 and became the first secular democratic Muslim-majority state. In 1920, the country was incorporated into the Soviet Union as the Azerbaijan SSR. The modern Republic of Azerbaijan proclaimed its independence on 30 August 1991, shortly before the dissolution of the Soviet Union in the same year. In September 1991, the ethnic Armenian majority of the Nagorno-Karabakh region formed the self-proclaimed Republic of Artsakh. The region and seven surrounding districts are internationally recognized as part of Azerbaijan, pending a solution to the status of Nagorno-Karabakh through negotiations facilitated by the OSCE, although became de facto independent with the end of the First Nagorno-Karabakh War in 1994. Following the Second Nagorno-Karabakh War in 2020, the seven districts and parts of Nagorno-Karabakh were returned to Azerbaijani control. Azerbaijan is a unitary semi-presidential republic. It is one of six independent Turkic states and an active member of the Organization of Turkic States and the TÜRKSOY community. Azerbaijan has diplomatic relations with 182 countries and holds membership in 38 international organizations, including the United Nations, the Council of Europe, the Non-Aligned Movement, the OSCE, and the NATO PfP program. It is one of the founding members of GUAM, the CIS, and the OPCW. Azerbaijan is also an observer state of the WTO. The vast majority of the country's population (97%) is nominally Muslim, but the constitution does not declare an official religion and all major political forces in the country are secularist. Azerbaijan is a developing country and ranks 91st on the Human Development Index. It has a high rate of economic development, literacy, and a low rate of unemployment. However, the ruling New Azerbaijan Party, in power since 1993, has been accused of authoritarian leadership under the leadership of both Heydar Aliyev and his son Ilham Aliyev, and deteriorating the country's human rights record, including increasing restrictions on civil liberties, particularly on press freedom and political repression. Etymology According to a modern etymology, the term Azerbaijan derives from that of Atropates, a Persian satrap under the Achaemenid Empire, who was later reinstated as the satrap of Media under Alexander the Great. The original etymology of this name is thought to have its roots in the once-dominant Zoroastrianism. In the Avesta's Frawardin Yasht ("Hymn to the Guardian Angels"), there is a mention of , which literally translates from Avestan as "we worship the fravashi of the holy Atropatene". The name "Atropates" itself is the Greek transliteration of an Old Iranian, probably Median, compounded name with the meaning "Protected by the (Holy) Fire" or "The Land of the (Holy) Fire". The Greek name was mentioned by Diodorus Siculus and Strabo. Over the span of millennia, the name evolved to (Middle Persian), then to , , (New Persian) and present-day Azerbaijan. The name Azerbaijan was first adopted for the area of the present-day Republic of Azerbaijan by the government of Musavat in 1918, after the collapse of the Russian Empire, when the independent Azerbaijan Democratic Republic was established. Until then, the designation had been used exclusively to identify the adjacent region of contemporary northwestern Iran, while the area of the Azerbaijan Democratic Republic was formerly referred to as Arran and Shirvan. On that basis Iran protested the newly adopted country name. During the Soviet rule, the country was also spelled in Latin from the Russian transliteration as (). The country's name was also spelled in Cyrillic script from 1940 to 1991 as . History Antiquity The earliest evidence of human settlement in the territory of Azerbaijan dates back to the late Stone Age and is related to the Guruchay culture of Azykh Cave. Early settlements included the Scythians during the 9th century BC. Following the Scythians, Iranian Medes came to dominate the area to the south of the Aras river. The Medes forged a vast empire between 900 and 700 BC, which was integrated into the Achaemenid Empire around 550 BC. The area was conquered by the Achaemenids leading to the spread of Zoroastrianism. From the Sasanid period to the Safavid period The Sasanian Empire turned Caucasian Albania into a vassal state in 252, while King Urnayr officially adopted Christianity as the state religion in the 4th century. Despite Sassanid rule, Albania remained an entity in the region until the 9th century, while fully subordinate to Sassanid Iran, and retained its monarchy. Despite being one of the chief vassals of the Sasanian emperor, the Albanian king had only a semblance of authority, and the Sasanian marzban (military governor) held most civil, religious, and military authority. In the first half of the 7th century, Caucasian Albania, as a vassal of the Sasanians, came under nominal Muslim rule due to the Muslim conquest of Persia. The Umayyad Caliphate repulsed both the Sasanians and Byzantines from the South Caucasus and turned Caucasian Albania into a vassal state after Christian resistance led by King Javanshir was suppressed in 667. The power vacuum left by the decline of the Abbasid Caliphate was filled by numerous local dynasties such as the Sallarids, Sajids, and Shaddadids. At the beginning of the 11th century, the territory was gradually seized by the waves of Oghuz Turks from Central Asia, who adopted a Turkoman ethnonym at the time. The first of these Turkic dynasties established was the Seljuk Empire, which entered the area now known as Azerbaijan by 1067. The pre-Turkic population that lived on the territory of modern Azerbaijan spoke several Indo-European and Caucasian languages, among them Armenian and an Iranian language, Old Azeri, which was gradually replaced by a Turkic language, the early precursor of the Azerbaijani language of today. Some linguists have also stated that the Tati dialects of Iranian Azerbaijan and the Republic of Azerbaijan, like those spoken by the Tats, are descended from Old Azeri. Locally, the possessions of the subsequent Seljuk Empire were ruled by Eldiguzids, technically vassals of the Seljuk sultans, but sometimes de facto rulers themselves. Under the Seljuks, local poets such as Nizami Ganjavi and Khaqani gave rise to a blossoming of Persian literature on the territory of present-day Azerbaijan. The local dynasty of the Shirvanshahs became a vassal state of Timur's empire and assisted him in his war with the ruler of the Golden Horde Tokhtamysh. Following Timur's death, two independent and rival states emerged: Qara Qoyunlu and Aq Qoyunlu. The Shirvanshahs returned, maintaining for numerous centuries to come a high degree of autonomy as local rulers and vassals as they had done since 861. In 1501, the Safavid dynasty of Iran subdued the Shirvanshahs and gained its possessions. In the course of the next century, the Safavids converted the formerly Sunni population to Shia Islam, as they did with the population in what is modern-day Iran. The Safavids allowed the Shirvanshahs to remain in power, under Safavid suzerainty, until 1538, when Safavid king Tahmasp I (r. 1524–1576) completely deposed them, and made the area into the Safavid province of Shirvan. The Sunni Ottomans briefly managed to occupy parts of present-day Azerbaijan as a result of the Ottoman–Safavid War of 1578–1590; by the early 17th century, they were ousted by Safavid Iranian ruler Abbas I (r. 1588–1629). In the wake of the demise of the Safavid Empire, Baku and its environs were briefly occupied by the Russians as a consequence of the Russo-Persian War of 1722–1723. Despite brief intermissions such as these by Safavid Iran's neighboring rivals, the land of what is today Azerbaijan remained under Iranian rule from the earliest advent of the Safavids up to the course of the 19th century. Modern history After the Safavids, the area was ruled by the Iranian Afsharid dynasty. After the death of Nader Shah (r. 1736–1747), many of his former subjects capitalized on the eruption of instability. Numerous self-ruling khanates with various forms of autonomy emerged in the area. The rulers of these khanates were directly related to the ruling dynasties of Iran and were vassals and subjects of the Iranian shah. The khanates exercised control over their affairs via international trade routes between Central Asia and the West. Thereafter, the area was under the successive rule of the Iranian Zands and Qajars. From the late 18th century, Imperial Russia switched to a more aggressive geo-political stance towards its two neighbors and rivals to the south, namely Iran and the Ottoman Empire. Russia now actively tried to gain possession of the Caucasus region which was, for the most part, in the hands of Iran. In 1804, the Russians invaded and sacked the Iranian town of Ganja, sparking the Russo-Persian War of 1804–1813. The militarily superior Russians ended the Russo-Persian War of 1804–1813 with a victory. Following Qajar Iran's loss in the 1804–1813 war, it was forced to concede suzerainty over most of the khanates, along with Georgia and Dagestan to the Russian Empire, per the Treaty of Gulistan. The area to the north of the river Aras, amongst which territory lies the contemporary Republic of Azerbaijan, was Iranian territory until Russia occupied it in the 19th century. About a decade later, in violation of the Gulistan treaty, the Russians invaded Iran's Erivan Khanate. This sparked the final bout of hostilities between the two, the Russo-Persian War of 1826–1828. The resulting Treaty of Turkmenchay, forced Qajar Iran to cede sovereignty over the Erivan Khanate, the Nakhchivan Khanate and the remainder of the Talysh Khanate, comprising the last parts of the soil of the contemporary Azerbaijani Republic that were still in Iranian hands. After the incorporation of all Caucasian territories from Iran into Russia, the new border between the two was set at the Aras River, which, upon the Soviet Union's disintegration, subsequently became part of the border between Iran and the Azerbaijan Republic. Qajar Iran was forced to cede its Caucasian territories to Russia in the 19th century, which thus included the territory of the modern-day Azerbaijan Republic, while as a result of that cession, the Azerbaijani ethnic group is nowadays parted between two nations: Iran and Azerbaijan. Despite the Russian conquest, throughout the entire 19th century, preoccupation with Iranian culture, literature, and language remained widespread amongst Shia and Sunni intellectuals in the Russian-held cities of Baku, Ganja and Tiflis (Tbilisi, now Georgia). Within the same century, in post-Iranian Russian-held East Caucasia, an Azerbaijani national identity emerged at the end of the 19th century. After the collapse of the Russian Empire during World War I, the short-lived Transcaucasian Democratic Federative Republic was declared, constituting the present-day republics of Azerbaijan, Georgia, and Armenia. It was followed by the March Days massacres that took place between 30 March and 2 April 1918 in the city of Baku and adjacent areas of the Baku Governorate of the Russian Empire. When the republic dissolved in May 1918, the leading Musavat party declared independence as the Azerbaijan Democratic Republic (ADR), adopting the name of "Azerbaijan" for the new republic; a name that prior to the proclamation of the ADR was solely used to refer to the adjacent northwestern region of contemporary Iran. The ADR was the first modern parliamentary republic in the Muslim world. Among the important accomplishments of the Parliament was the extension of suffrage to women, making Azerbaijan the first Muslim nation to grant women equal political rights with men. Another important accomplishment of ADR was the establishment of Baku State University, which was the first modern-type university founded in the Muslim East. By March 1920, it was obvious that Soviet Russia would attack Baku. Vladimir Lenin said that the invasion was justified as Soviet Russia could not survive without Baku's oil. Independent Azerbaijan lasted only 23 months until the Bolshevik 11th Soviet Red Army invaded it, establishing the Azerbaijan SSR on 28 April 1920. Although the bulk of the newly formed Azerbaijani army was engaged in putting down an Armenian revolt that had just broken out in Karabakh, Azerbaijanis did not surrender their brief independence of 1918–20 quickly or easily. As many as 20,000 Azerbaijani soldiers died resisting what was effectively a Russian reconquest. Within the ensuing early Soviet period, the Azerbaijani national identity was finally forged. On 13 October 1921, the Soviet republics of Russia, Armenia, Azerbaijan, and Georgia signed an agreement with Turkey known as the Treaty of Kars. The previously independent Republic of Aras would also become the Nakhchivan Autonomous Soviet Socialist Republic within the Azerbaijan SSR by the treaty of Kars. On the other hand, Armenia was awarded the region of Zangezur and Turkey agreed to return Gyumri (then known as Alexandropol). During World War II, Azerbaijan played a crucial role in the strategic energy policy of the Soviet Union, with 80 percent of the Soviet Union's oil on the Eastern Front being supplied by Baku. By the Decree of the Supreme Soviet of the USSR in February 1942, the commitment of more than 500 workers and employees of the oil industry of Azerbaijan were awarded orders and medals. Operation Edelweiss carried out by the German Wehrmacht targeted Baku because of its importance as the energy (petroleum) dynamo of the USSR. A fifth of all Azerbaijanis fought in the Second World War from 1941 to 1945. Approximately 681,000 people with over 100,000 of them women, went to the front, while the total population of Azerbaijan was 3.4 million at the time. Some 250,000 people from Azerbaijan were killed on the front. More than 130 Azerbaijanis were named Heroes of the Soviet Union. Azerbaijani Major-General Azi Aslanov was twice awarded the Hero of the Soviet Union. Independence Following the politics of glasnost, initiated by Mikhail Gorbachev, civil unrest and ethnic strife grew in various regions of the Soviet Union, including Nagorno-Karabakh, an autonomous region of the Azerbaijan SSR. The disturbances in Azerbaijan, in response to Moscow's indifference to an already heated conflict, resulted in calls for independence and secession, which culminated in the Black January events in Baku. Later in 1990, the Supreme Council of the Azerbaijan SSR dropped the words "Soviet Socialist" from the title, adopted the "Declaration of Sovereignty of the Azerbaijan Republic" and restored the flag of the Azerbaijan Democratic Republic as the state flag. As a consequence of the failed 1991 Soviet coup d'état attempt in Moscow, the Supreme Council of Azerbaijan adopted a Declaration of Independence on 18 October 1991, which was affirmed by a nationwide referendum in December 1991, while the Soviet Union officially ceased to exist on 26 December 1991. The country now celebrates its Independence Day on 18 October. The early years of independence were overshadowed by the First Nagorno-Karabakh war with the ethnic Armenian majority of Nagorno-Karabakh backed by Armenia. By the end of the hostilities in 1994, Armenians controlled up to 14–16 percent of Azerbaijani territory, including Nagorno-Karabakh itself. During the war many atrocities and pogroms by both sides were committed including the massacres at Malibeyli and Gushchular, the Garadaghly massacre and the Khojaly massacres, along with the Baku pogrom, the Maraga massacre and the Kirovabad pogrom. Furthermore, an estimated 30,000 people have been killed and more than a million people have been displaced, more than 800,000 Azerbaijanis and 300,000 Armenians. Four United Nations Security Council Resolutions (822, 853, 874, and 884) demand for "the immediate withdrawal of all Armenian forces from all occupied territories of Azerbaijan." Many Russians and Armenians left and fled Azerbaijan as refugees during the 1990s. According to the 1970 census, there were 510,000 ethnic Russians and 484,000 Armenians in Azerbaijan. Heydar Aliyev, 1993–today In 1993, democratically elected president Abulfaz Elchibey was overthrown by a military insurrection led by Colonel Surat Huseynov, which resulted in the rise to power of the former leader of Soviet Azerbaijan, Heydar Aliyev. In 1994, Surat Huseynov, by that time the prime minister, attempted another military coup against Heydar Aliyev, but he was arrested and charged with treason. A year later, in 1995, another coup was attempted against Aliyev, this time by the commander of the OMON special unit, Rovshan Javadov. The coup was averted, resulting in the killing of the latter and disbanding of Azerbaijan's OMON units. At the same time, the country was tainted by rampant corruption in the governing bureaucracy. In October 1998, Aliyev was reelected for a second term. Despite the much improved economy, particularly with the exploitation of the Azeri–Chirag–Guneshli oil field and Shah Deniz gas field, Aliyev's presidency was criticized due to suspected election fraud, high levels of economic inequality and domestic corruption. Ilham Aliyev, Heydar Aliyev's son, became chairman of the New Azerbaijan Party as well as President of Azerbaijan when his father died in 2003. He was reelected to a third term as president in October 2013. In April 2018, President Ilham Aliyev secured his fourth consecutive term in the election that was boycotted by the main opposition parties as fraudulent. On 27 September 2020, new clashes in the unresolved Nagorno-Karabakh conflict resumed along the Nagorno-Karabakh Line of Contact. Both the armed forces of Azerbaijan and Armenia reported military and civilian casualties. The Nagorno-Karabakh ceasefire agreement and the end of the six-week war between Azerbaijan and Armenia was widely celebrated in Azerbaijan, as they made significant territorial gains. Geography Geographically, Azerbaijan is located in the South Caucasus region of Eurasia, straddling Western Asia and Eastern Europe. It lies between latitudes 38° and 42° N, and longitudes 44° and 51° E. The total length of Azerbaijan's land borders is , of which are with Armenia, with Iran, 480 kilometers with Georgia, with Russia and with Turkey. The coastline stretches for , and the length of the widest area of the Azerbaijani section of the Caspian Sea is . The country has a landlocked exclave, the Nakhchivan Autonomous Republic. Three physical features dominate Azerbaijan: the Caspian Sea, whose shoreline forms a natural boundary to the east; the Greater Caucasus mountain range to the north; and the extensive flatlands at the country's center. There are also three mountain ranges, the Greater and Lesser Caucasus, and the Talysh Mountains, together covering approximately 40% of the country. The highest peak of Azerbaijan is Mount Bazardüzü , while the lowest point lies in the Caspian Sea . Nearly half of all the mud volcanoes on Earth are concentrated in Azerbaijan, these volcanoes were also among nominees for the New7Wonders of Nature. The main water sources are surface waters. Only 24 of the 8,350 rivers are greater than in length. All the rivers drain into the Caspian Sea in the east of the country. The largest lake is Sarysu , and the longest river is Kur , which is transboundary with Armenia. Azerbaijan has several islands along the Caspian sea, mostly located in the Baku Archipelago. Since the independence of Azerbaijan in 1991, the Azerbaijani government has taken measures to preserve the environment of Azerbaijan. National protection of the environment accelerated after 2001 when the state budget increased due to new revenues provided by the Baku–Tbilisi–Ceyhan pipeline. Within four years, protected areas doubled and now make up eight percent of the country's territory. Since 2001 the government has set up seven large reserves and almost doubled the sector of the budget earmarked for environmental protection. Landscape Azerbaijan is home to a wide variety of landscapes. Over half of Azerbaijan's landmass consists of mountain ridges, crests, highlands, and plateaus which rise up to hypsometric levels of 400–1000 meters (including the Middle and Lower lowlands), in some places (Talis, Jeyranchol-Ajinohur and Langabiz-Alat foreranges) up to 100–120 meters, and others from 0–50 meters and up (Qobustan, Absheron). The rest of Azerbaijan's terrain consists of plains and lowlands. Hypsometric marks within the Caucasus region vary from about −28 meters at the Caspian Sea shoreline up to 4,466 meters (Bazardüzü peak). The formation of climate in Azerbaijan is influenced particularly by cold arctic air masses of Scandinavian anticyclone, temperate air masses of Siberian anticyclone, and Central Asian anticyclone. Azerbaijan's diverse landscape affects the ways air masses enter the country. The Greater Caucasus protects the country from direct influences of cold air masses coming from the north. That leads to the formation of subtropical climate on most foothills and plains of the country. Meanwhile, plains and foothills are characterized by high solar radiation rates. Nine out of eleven existing climate zones are present in Azerbaijan. Both the absolute minimum temperature ( ) and the absolute maximum temperature were observed in Julfa and Ordubad – regions of Nakhchivan Autonomous Republic. The maximum annual precipitation falls in Lankaran () and the minimum in Absheron (). Rivers and lakes form the principal part of the water systems of Azerbaijan, they were formed over a long geological timeframe and changed significantly throughout that period. This is particularly evidenced by remnants of ancient rivers found throughout the country. The country's water systems are continually changing under the influence of natural forces and human-introduced industrial activities. Artificial rivers (canals) and ponds are a part of Azerbaijan's water systems. In terms of water supply, Azerbaijan is below the average in the world with approximately per year of water per square kilometer. All big water reservoirs are built on Kur. The hydrography of Azerbaijan basically belongs to the Caspian Sea basin. The Kura and Aras are the major rivers in Azerbaijan. They run through the Kura-Aras Lowland. The rivers that directly flow into the Caspian Sea, originate mainly from the north-eastern slope of the Major Caucasus and Talysh Mountains and run along the Samur–Devechi and Lankaran lowlands. Yanar Dag, translated as "burning mountain", is a natural gas fire which blazes continuously on a hillside on the Absheron Peninsula on the Caspian Sea near Baku, which itself is known as the "land of fire." Flames jet out into the air from a thin, porous sandstone layer. It is a tourist attraction to visitors to the Baku area. Biodiversity The first reports on the richness and diversity of animal life in Azerbaijan can be found in travel notes of Eastern travelers. Animal carvings on architectural monuments, ancient rocks, and stones survived up to the present times. The first information on flora and fauna of Azerbaijan was collected during the visits of naturalists to Azerbaijan in the 17th century. There are 106 species of mammals, 97 species of fish, 363 species of birds, 10 species of amphibians, and 52 species of reptiles which have been recorded and classified in Azerbaijan. The national animal of Azerbaijan is the Karabakh horse, a mountain-steppe racing and riding horse endemic to Azerbaijan. The Karabakh horse has a reputation for its good temper, speed, elegance, and intelligence. It is one of the oldest breeds, with ancestry dating to the ancient world, but today the horse is an endangered species. Azerbaijan's flora consists of more than 4,500 species of higher plants. Due to the unique climate in Azerbaijan, the flora is much richer in the number of species than the flora of the other republics of the South Caucasus. 66 percent of the species growing in the whole Caucasus can be found in Azerbaijan. The country lies within four ecoregions: Caspian Hyrcanian mixed forests, Caucasus mixed forests, Eastern Anatolian montane steppe, and Azerbaijan shrub desert and steppe. Azerbaijan had a 2018 Forest Landscape Integrity Index mean score of 6.55/10, ranking it 72nd globally out of 172 countries. Government and politics The structural formation of Azerbaijan's political system was completed by the adoption of the new Constitution on 12 November 1995. According to Article 23 of the Constitution, the state symbols of the Azerbaijan Republic are the flag, the coat of arms, and the national anthem. The state power in Azerbaijan is limited only by law for internal issues, but international affairs are also limited by international agreements' provisions. The Constitution of Azerbaijan states that it is a presidential republic with three branches of power – Executive, Legislative, and Judicial. The legislative power is held by the unicameral National Assembly and the Supreme National Assembly in the Nakhchivan Autonomous Republic. The Parliament of Azerbaijan, called Milli Majlis, consists of 125 deputies elected based on majority vote, with a term of five years for each elected member. The elections are held every five years, on the first Sunday of November. The Parliament is not responsible for the formation of the government, but the Constitution requires the approval of the Cabinet of Ministers by Milli Majlis. The New Azerbaijan Party, and independents loyal to the ruling government, currently hold almost all of the Parliament's 125 seats. During the 2010 Parliamentary election, the opposition parties, Musavat and Azerbaijani Popular Front Party, failed to win a single seat. European observers found numerous irregularities in the run-up to the election and on election day. The executive power is held by the President, who is elected for a seven-year term by direct elections, and the Prime Minister. The president is authorized to form the Cabinet, a collective executive body accountable to both the President and the National Assembly. The Cabinet of Azerbaijan consists primarily of the prime minister, his deputies, and ministers. The 8th Government of Azerbaijan is the administration in its current formation. The president does not have the right to dissolve the National Assembly but has the right to veto its decisions. To override the presidential veto, the parliament must have a majority of 95 votes. The judicial power is vested in the Constitutional Court, Supreme Court, and the Economic Court. The president nominates the judges in these courts. The European Commission for the Efficiency of Justice (CEPEJ) report refers to the Azerbaijani justice model on the selection of new judges as best practice, reflecting the particular features and the course of development towards ensuring the independence and quality of the judiciary in a new democracy. Azerbaijan's system of governance nominally can be called two-tiered. The top or highest tier of the government is the Executive Power headed by President. The President appoints the Cabinet of Ministers and other high-ranking officials. The Local Executive Authority is merely a continuation of Executive Power. The Provision determines the legal status of local state administration in Azerbaijan on Local Executive Authority (Yerli Icra Hakimiyati), adopted 16 June 1999. In June 2012, the President approved the new Regulation, which granted additional powers to Local Executive Authorities, strengthening their dominant position in Azerbaijan's local affairs Chapter 9 of the Constitution of the Azerbaijan Republic addresses major issues of local self-government, such as the legal status of municipalities, types of local self-government bodies, their basic powers and relationships to other official entities. The other nominal tier of governance is municipalities (Bələdiyə), and members of municipalities are elected by a general vote in Municipal elections every five years. Currently, there are 1,607 municipalities across the country. The Law on Municipal Elections and the Law on the Status of Municipalities were the first to be adopted in the field of local government (2 July 1999). The Law on Municipal Service regulates the activities of municipal employees, their rights, duties, labor conditions, and social benefits and outlines the structure of the executive apparatus and the organization of municipal service. The Law on the Status of Municipalities regulates the role and structure of municipal bodies and outlines state guarantees of legal and financial autonomy. The law pays special attention to the adoption and execution of municipal programs concerning social protection, social and economic development, and the local environment. The Security Council is the deliberative body under the president, and he organizes it according to the Constitution. It was established on 10 April 1997. The administrative department is not a part of the president's office but manages the financial, technical and pecuniary activities of both the president and his office. Azerbaijan's political system has been defined by some political scientists as authoritarian, due to the long-lasting influence of the Aliyev political family and the New Azerbaijan Party (Yeni Azərbaycan Partiyası, YAP) established by Heydar Aliyev. The country's third President, Heydar Aliyev (in office between 1993 and 2003; he was previously the First Secretary of the Communist Party of Azerbaijan between 1969 and 1982, and First Deputy Premier of the Soviet Union between 1982 and 1987) was succeeded by his son, the fourth and current President Ilham Aliyev, in 2003. Although Azerbaijan has held numerous elections since regaining its independence and has many of the formal institutions of a democracy, it remains categorised as "not free" by Freedom House, who ranked it 9/100 on Global Freedom Score in 2022, calling it a "consolidated authoritarian regime". In recent years, large numbers of Azerbaijani journalists, bloggers, lawyers, and human rights activists have been rounded up and jailed for their criticism of President Aliyev and government authorities. A resolution adopted by the European Parliament in September 2015 described Azerbaijan as "having suffered the greatest decline in democratic governance in all of Eurasia over the past ten years," noting as well that its dialogue with the country on human rights has "not made any substantial progress." On 17 March 2016, the President of Azerbaijan signed a decree pardoning more than a dozen of the persons regarded as political prisoners by some NGOs. This decree was welcomed as a positive step by the US State Department. On 16 March 2017 another pardon decree was signed, which led to the release of additional persons regarded as political prisoners. Azerbaijan has been harshly criticized for bribing foreign officials and diplomats to promote its causes abroad and legitimize its elections at home, a practice termed caviar diplomacy. However, on 6 March 2017, the European Strategic Intelligence and Security Center ESISC) published a report called "The Armenian Connection", in which it attacked human rights NGOs and research organisations criticising human rights violations and corruption in Azerbaijan. ESISC in that report asserted that the "Caviar Diplomacy" report elaborated by ESI aimed to create a climate of suspicion based on slander to form a network of MPs that would engage in a political war against Azerbaijan and that the network, composed of European PMs, Armenian officials, and some NGOs (Human Rights Watch, Amnesty International, "Human Rights House Foundation", "Open Dialog, European Stability Initiative, and Helsinki Committee for Human Rights) was financed by the Soros Foundation. According to Robert Coalson (Radio Free Europe), ESISC is a part of Baku's lobbying efforts to extend the use of front think tanks to shift public opinion. Freedom Files Analytical Centre said that "The report is written in the worst traditions of authoritarian propaganda". Foreign relations The short-lived Azerbaijan Democratic Republic succeeded in establishing diplomatic relations with six countries, sending diplomatic representatives to Germany and Finland. The process of international recognition of Azerbaijan's independence from the collapsing Soviet Union lasted roughly one year. The most recent country to recognize Azerbaijan was Bahrain, on 6 November 1996. Full diplomatic relations, including mutual exchanges of missions, were first established with Turkey, Pakistan, the United States, Iran and Israel. Azerbaijan has placed a particular emphasis on its "special relationship" with Turkey. Azerbaijan has diplomatic relations with 158 countries so far and holds membership in 38 international organizations. It holds observer status in the Non-Aligned Movement and World Trade Organization and is a correspondent at the International Telecommunication Union. On 9 May 2006 Azerbaijan was elected to membership in the newly established Human Rights Council by the United Nations General Assembly. The term of office began on 19 June 2006. Azerbaijan was first elected as a non-permanent member of the UN Security Council in 2011 with the support of 155 countries. Foreign policy priorities of Azerbaijan include, first of all, the restoration of its territorial integrity; elimination of the consequences of occupation of Nagorno-Karabakh and seven other regions of Azerbaijan surrounding Nagorno-Karabakh; integration into European and Euro-Atlantic structure; contribution to international security; cooperation with international organizations; regional cooperation and bilateral relations; strengthening of defense capability; promotion of security by domestic policy means; strengthening of democracy; preservation of ethnic and religious tolerance; scientific, educational, and cultural policy and preservation of moral values; economic and social development; enhancing internal and border security; and migration, energy, and transportation security policy. Azerbaijan is an active member of international coalitions fighting international terrorism, and was one of the first countries to offer support after the September 11 attacks. The country is an active member of NATO's Partnership for Peace program, contributing to peacekeeping efforts in Kosovo, Afghanistan and Iraq. Azerbaijan is also a member of the Council of Europe since 2001 and maintains good relations with the European Union. The country may eventually apply for EU membership. On 1 July 2021, the US Congress advanced legislation that will have an impact on the military aid that Washington has sent to Azerbaijan since 2012. This was due to the fact that the packages to Armenia, instead, are significantly smaller. Military The history of the modern Azerbaijan army dates back to Azerbaijan Democratic Republic in 1918 when the National Army of the newly formed Azerbaijan Democratic Republic was created on 26 June 1918. When Azerbaijan gained independence after the dissolution of the Soviet Union, the Armed Forces of the Republic of Azerbaijan were created according to the Law on the Armed Forces of 9 October 1991. The original date of the establishment of the short-lived National Army is celebrated as Army Day (26 June) in today's Azerbaijan. As of 2021, Azerbaijan had 126,000 active personnel in its armed forces. There are also 17,000 paramilitary troops and 330,00 reserve personnel. The armed forces have three branches: the Land Forces, the Air Forces and the Navy. Additionally the armed forces embrace several military sub-groups that can be involved in state defense when needed. These are the Internal Troops of the Ministry of Internal Affairs and the State Border Service, which includes the Coast Guard as well. The Azerbaijan National Guard is a further paramilitary force. It operates as a semi-independent entity of the Special State Protection Service, an agency subordinate to the President. Azerbaijan adheres to the Treaty on Conventional Armed Forces in Europe and has signed all major international arms and weapons treaties. Azerbaijan closely cooperates with NATO in programs such as Partnership for Peace and Individual Partnership Action Plan/pfp and ipa. Azerbaijan has deployed 151 of its Peacekeeping Forces in Iraq and another 184 in Afghanistan. Azerbaijan spent $2.24 billion on its defence budget , which amounted to 5.4% of its total GDP, and some 12.7% of general government expenditure. Azerbaijani defense industry manufactures small arms, artillery systems, tanks, armors and noctovision devices, aviation bombs, UAV'S/unmanned aerial vehicle, various military vehicles and military planes and helicopters. Administrative divisions Azerbaijan is administratively divided into 14 economic regions; 66 rayons (, singular ) and 11 cities (, singular ) under the direct authority of the republic. Moreover, Azerbaijan includes the Autonomous Republic () of Nakhchivan. The President of Azerbaijan appoints the governors of these units, while the government of Nakhchivan is elected and approved by the parliament of Nakhchivan Autonomous Republic. Economy After gaining independence in 1991, Azerbaijan became a member of the International Monetary Fund, the World Bank, the European Bank for Reconstruction and Development, the Islamic Development Bank, and the Asian Development Bank. The banking system of Azerbaijan consists of the Central Bank of Azerbaijan, commercial banks, and non-banking credit organizations. The National (now Central) Bank was created in 1992 based on the Azerbaijan State Savings Bank, an affiliate of the former State Savings Bank of the USSR. The Central Bank serves as Azerbaijan's central bank, empowered to issue the national currency, the Azerbaijani manat, and to supervise all commercial banks. Two major commercial banks are UniBank and the state-owned International Bank of Azerbaijan, run by Abbas Ibrahimov. Pushed up by spending and demand growth, the 2007 Q1 inflation rate reached 16.6%. Nominal incomes and monthly wages climbed 29% and 25% respectively against this figure, but price increases in the non-oil industry encouraged inflation. Azerbaijan shows some signs of the so-called "Dutch disease" because of its fast-growing energy sector, which causes inflation and makes non-energy exports more expensive. In the early 2000s, chronically high inflation was brought under control. This led to the launch of a new currency, the new Azerbaijani manat, on 1 January 2006, to cement the economic reforms and erase the vestiges of an unstable economy. Azerbaijan is also ranked 57th in the Global Competitiveness Report for 2010–2011, above other CIS countries. By 2012 the GDP of Azerbaijan had increased 20-fold from its 1995 level. Energy and natural resources Two-thirds of Azerbaijan is rich in oil and natural gas. The history of the oil industry of Azerbaijan dates back to the ancient period. Arabian historian and traveler Ahmad Al-Baladhuri discussed the economy of the Absheron peninsula in antiquity, mentioning its oil in particular. There are many pipelines in Azerbaijan. The goal of the Southern Gas Corridor, which connects the giant Shah Deniz gas field in Azerbaijan to Europe, is to reduce European Union's dependency on Russian gas. The region of the Lesser Caucasus accounts for most of the country's gold, silver, iron, copper, titanium, chromium, manganese, cobalt, molybdenum, complex ore and antimony. In September 1994, a 30-year contract was signed between the State Oil Company of Azerbaijan Republic (SOCAR) and 13 oil companies, among them Amoco, BP, ExxonMobil, Lukoil and Equinor. As Western oil companies are able to tap deepwater oilfields untouched by the Soviet exploitation, Azerbaijan is considered one of the most important spots in the world for oil exploration and development. Meanwhile, the State Oil Fund of Azerbaijan was established as an extra-budgetary fund to ensure macroeconomic stability, transparency in the management of oil revenue, and safeguarding of resources for future generations. Access to biocapacity in Azerbaijan is less than world average. In 2016, Azerbaijan had 0.8 global hectares of biocapacity per person within its territory, half the world average of 1.6 global hectares per person. In 2016 Azerbaijan used 2.1 global hectares of biocapacity per person – their ecological footprint of consumption. This means they use more biocapacity than Azerbaijan contains. As a result, Azerbaijan is running a biocapacity deficit. Azeriqaz, a sub-company of SOCAR, intends to ensure full gasification of the country by 2021. Azerbaijan is one of the sponsors of the east–west and north–south energy transport corridors. Baku–Tbilisi–Kars railway line will connect the Caspian region with Turkey, which is expected to be completed in July 2017. The Trans-Anatolian gas pipeline (TANAP) and Trans Adriatic Pipeline (TAP) will deliver natural gas from Azerbaijan's Shah Deniz gas to Turkey and Europe. Azerbaijan extended the agreement on development of ACG until 2050 according to the amended PSA signed on 14 September 2017 by SOCAR and co-ventures (BP, Chevron, Inpex, Equinor, ExxonMobil, TP, ITOCHU and ONGC Videsh). Agriculture Azerbaijan has the largest agricultural basin in the region. About 54.9 percent of Azerbaijan is agricultural land. At the beginning of 2007 there were 4,755,100 hectares of utilized agricultural area. In the same year the total wood resources counted 136 million m3. Azerbaijan's agricultural scientific research institutes are focused on meadows and pastures, horticulture and subtropical crops, green vegetables, viticulture and wine-making, cotton growing and medicinal plants. In some areas it is profitable to grow grain, potatoes, sugar beets, cotton and tobacco. Livestock, dairy products, and wine and spirits are also important farm products. The Caspian fishing industry concentrates on the dwindling stocks of sturgeon and beluga. In 2002 the Azerbaijani merchant marine had 54 ships. Some products previously imported from abroad have begun to be produced locally. Among them are Coca-Cola by Coca-Cola Bottlers LTD., beer by Baki-Kastel, parquet by Nehir and oil pipes by EUPEC Pipe Coating Azerbaijan. Tourism Tourism is an important part of the economy of Azerbaijan. The country was a well-known tourist spot in the 1980s. The fall of the Soviet Union, and the First Nagorno-Karabakh War during the 1990s, damaged the tourist industry and the image of Azerbaijan as a tourist destination. It was not until the 2000s that the tourism industry began to recover, and the country has since experienced a high rate of growth in the number of tourist visits and overnight stays. In recent years, Azerbaijan has also become a popular destination for religious, spa, and health care tourism. During winter, the Shahdag Mountain Resort offers skiing with state of the art facilities. The government of Azerbaijan has set the development of Azerbaijan as an elite tourist destination as a top priority. It is a national strategy to make tourism a major, if not the single largest, contributor to the Azerbaijani economy. These activities are regulated by the Ministry of Culture and Tourism of Azerbaijan. There are 63 countries which have a visa-free score. E-visa – for a visit of foreigners of visa-required countries to the Republic of Azerbaijan. According to the Travel and Tourism Competitiveness Report 2015 of the World Economic Forum, Azerbaijan holds 84th place. According to a report by the World Travel and Tourism Council, Azerbaijan was among the top ten countries showing the strongest growth in visitor exports between 2010 and 2016, In addition, Azerbaijan placed first (46.1%) among countries with the fastest-developing travel and tourism economies, with strong indicators for inbound international visitor spending last year. Transportation The convenient location of Azerbaijan on the crossroad of major international traffic arteries, such as the Silk Road and the south–north corridor, highlights the strategic importance of the transportation sector for the country's economy. The transport sector in the country includes roads, railways, aviation, and maritime transport. Azerbaijan is also an important economic hub in the transportation of raw materials. The Baku–Tbilisi–Ceyhan pipeline (BTC) became operational in May 2006 and extends more than through the territories of Azerbaijan, Georgia, and Turkey. The BTC is designed to transport up to 50 million tons of crude oil annually and carries oil from the Caspian Sea oilfields to global markets. The South Caucasus Pipeline, also stretching through the territory of Azerbaijan, Georgia, and Turkey, became operational at the end of 2006 and offers additional gas supplies to the European market from the Shah Deniz gas field. Shah Deniz is expected to produce up to 296 billion cubic meters of natural gas per year. Azerbaijan also plays a major role in the EU-sponsored Silk Road Project. In 2002, the Azerbaijani government established the Ministry of Transport with a broad range of policy and regulatory functions. In the same year, the country became a member of the Vienna Convention on Road Traffic. Priorities are upgrading the transport network and improving transportation services to better facilitate the development of other sectors of the economy. The 2012 construction of Kars–Tbilisi–Baku railway was meant to improve transportation between Asia and Europe by connecting the railways of China and Kazakhstan in the east to the European railway system in the west via Turkey. In 2010 Broad-gauge railways and electrified railways stretched for and respectively. By 2010, there were 35 airports and one heliport. Science and technology In the 21st century, a new oil and gas boom helped improve the situation in Azerbaijan's science and technology sectors. The government launched a campaign aimed at modernization and innovation. The government estimates that profits from the information technology and communication industry will grow and become comparable to those from oil production. Azerbaijan has a large and steadily growing Internet sector, mostly uninfluenced by the financial crisis of 2007–2008; rapid growth is forecast for at least five more years. Azerbaijan was ranked 80th in the Global Innovation Index in 2021, up from 84th in 2019. The country has also been making progress in developing its telecoms sector. The Ministry of Communications & Information Technologies (MCIT) and an operator through its role in Aztelekom are both policy-makers and regulators. Public payphones are available for local calls and require the purchase of a token from the telephone exchange or some shops and kiosks. Tokens allow a call of indefinite duration. , there were 1,397,000 main telephone lines and 1,485,000 internet users. There are four GSM providers: Azercell, , Azerfon (Nar Mobile), Nakhtel mobile network operators and one CDMA. In the 21st century a number of prominent Azerbaijani geodynamics and geotectonics scientists, inspired by the fundamental works of Elchin Khalilov and others, designed hundreds of earthquake prediction stations and earthquake-resistant buildings that now constitute the bulk of The Republican Center of Seismic Service. The Azerbaijan National Aerospace Agency launched its first satellite AzerSat 1 into orbit on 7 February 2013 from Guiana Space Centre in French Guiana at orbital positions 46° East. The satellite covers Europe and a significant part of Asia and Africa and serves the transmission of TV and radio broadcasting as well as the Internet. The launching of a satellite into orbit is Azerbaijan's first step in realizing its goal of becoming a nation with its own space industry, capable of successfully implementing more projects in the future. Demographics As of March 2022, 52.9% of Azerbaijan's total population of 10,164,464 is urban, with the remaining 47.1% being rural. In January 2019, the 50.1% of the total population was female. The sex ratio in the same year was 0.99 males per female. The 2011 population growth-rate was 0.85%, compared to 1.09% worldwide. A significant factor restricting population growth is a high level of migration. In 2011 Azerbaijan saw a migration of −1.14/1,000 people. The Azerbaijani diaspora is found in 42 countries and in turn there are many centers for ethnic minorities inside Azerbaijan, including the German cultural society "Karelhaus", Slavic cultural center, Azerbaijani-Israeli community, Kurdish cultural center, International Talysh Association, Lezgin national center "Samur", Azerbaijani-Tatar community, Crimean Tatars society, etc. In total, Azerbaijan has 78 cities, 63 city districts, and one special legal status city. 261 urban-type settlements and 4248 villages follow these. Ethnicity The ethnic composition of the population according to the 2009 population census: 91.6% Azerbaijanis, 2.0% Lezgins, 1.4% Armenians (almost all Armenians live in the break-away region of Nagorno-Karabakh), 1.3% Russians, 1.3% Talysh, 0.6% Avars, 0.4% Turks, 0.3% Tatars, 0.3% Tats, 0.2% Ukrainians, 0.1% Tsakhurs, 0.1% Georgians, 0.1% Jews, 0.1% Kurds, other 0.2%. Languages The official language is Azerbaijani, which is a Turkic language. Azerbaijani is spoken by approximately 92% of the population as a mother tongue. Russian and Armenian (only in Nagorno-Karabakh) are also spoken, and each are the mother tongue of around 1.5% of the population respectively. There are a dozen other minority languages spoken natively in the country. Avar, Budukh, Georgian, Juhuri, Khinalug, Kryts, Lezgin, Rutul, Talysh, Tat, Tsakhur, and Udi are all spoken by small minorities. Some of these language communities are very small and their numbers are decreasing. Armenian was the majority language in Nagorno-Karabakh with around 76% in 1989. After the first Nagorno-Karabakh war, the population is almost exclusively Armenian at around 95%. Religion Azerbaijan is considered the most secular Muslim-majority country. Around 97% of the population are Muslims. Around 55-65% of Muslims are estimated to be Shia, while 35-45% of Muslims are Sunnis. Other faiths are practised by the country's various ethnic groups. Under article 48 of its Constitution, Azerbaijan is a secular state and ensures religious freedom. In a 2006–2008 Gallup poll, only 21% of respondents from Azerbaijan stated that religion is an important part of their daily lives. Of the nation's religious minorities, the estimated 280,000 Christians (3.1%) are mostly Russian and Georgian Orthodox and Armenian Apostolic (almost all Armenians live in the break-away region of Nagorno-Karabakh). In 2003, there were 250 Roman Catholics. Other Christian denominations as of 2002 include Lutherans, Baptists and Molokans. There is also a small Protestant community. Azerbaijan also has an ancient Jewish population with a 2,000-year history; Jewish organizations estimate that 12,000 Jews remain in Azerbaijan, which is home to the only Jewish-majority town outside of Israel and the United States. Azerbaijan also is home to members of the Baháʼí, Hare Krishna and Jehovah's Witnesses communities, as well as adherents of the other religious communities. Some religious communities have been unofficially restricted from religious freedom. A U.S. State Department report on the matter mentions detention of members of certain Muslim and Christian groups, and many groups have difficulty registering with the agency who regulates religion, The State Committee on Religious Associations of the Republic of Azerbaijan (SCWRA). Education A relatively high percentage of Azerbaijanis have obtained some form of higher education, most notably in scientific and technical subjects. In the Soviet era, literacy and average education levels rose dramatically from their very low starting point, despite two changes in the standard alphabet, from Perso-Arabic script to Latin in the 1920s and from Roman to Cyrillic in the 1930s. According to Soviet data, 100 percent of males and females (ages nine to forty-nine) were literate in 1970. According to the United Nations Development Program Report 2009, the literacy rate in Azerbaijan is 99.5 percent. Since independence, one of the first laws that Azerbaijan's Parliament passed to disassociate itself from the Soviet Union was to adopt a modified-Latin alphabet to replace Cyrillic. Other than that the Azerbaijani system has undergone little structural change. Initial alterations have included the reestablishment of religious education (banned during the Soviet period) and curriculum changes that have reemphasized the use of the Azerbaijani language and have eliminated ideological content. In addition to elementary schools, the education institutions include thousands of preschools, general secondary schools, and vocational schools, including specialized secondary schools and technical schools. Education through the ninth grade is compulsory. Culture The culture of Azerbaijan has developed as a result of many influences; that's why Azerbaijanis are, in many ways, bi-cultural. Today, national traditions are well preserved in the country despite Western influences, including globalized consumer culture. Some of the main elements of the Azerbaijani culture are: music, literature, folk dances and art, cuisine, architecture, cinematography and Novruz Bayram. The latter is derived from the traditional celebration of the New Year in the ancient Iranian religion of Zoroastrianism. Novruz is a family holiday. The profile of Azerbaijan's population consists, as stated above, of Azerbaijanis, as well as other nationalities or ethnic groups, compactly living in various areas of the country. Azerbaijani national and traditional dresses are the Chokha and Papakhi. There are radio broadcasts in Russian, Georgian, Kurdish, Lezgian and Talysh languages, which are financed from the state budget. Some local radio stations in Balakan and Khachmaz organize broadcasts in Avar and Tat. In Baku several newspapers are published in Russian, Kurdish (Dengi Kurd), Lezgian (Samur) and Talysh languages. Jewish society "Sokhnut" publishes the newspaper Aziz. Music and folk dances Music of Azerbaijan builds on folk traditions that reach back nearly a thousand years. For centuries Azerbaijani music has evolved under the badge of monody, producing rhythmically diverse melodies. Azerbaijani music has a branchy mode system, where chromatization of major and minor scales is of great importance. Among national musical instruments there are 14 string instruments, eight percussion instruments and six wind instruments. According to The Grove Dictionary of Music and Musicians, "in terms of ethnicity, culture and religion the Azerbaijani are musically much closer to Iran than Turkey." Mugham, meykhana and ashiq art are among the many musical traditions of Azerbaijan. Mugham is usually a suite with poetry and instrumental interludes. When performing mugham, the singers have to transform their emotions into singing and music. In contrast to the mugham traditions of Central Asian countries, Azerbaijani mugham is more free-form and less rigid; it is often compared to the improvised field of jazz. UNESCO proclaimed the Azerbaijani mugham tradition a Masterpiece of the Oral and Intangible Heritage of Humanity on 7 November 2003. Meykhana is a kind of traditional Azerbaijani distinctive folk unaccompanied song, usually performed by several people improvising on a particular subject. Ashiq combines poetry, storytelling, dance, and vocal and instrumental music into a traditional performance art that stands as a symbol of Azerbaijani culture. It is a mystic troubadour or traveling bard who sings and plays the saz. This tradition has its origin in the Shamanistic beliefs of ancient Turkic peoples. Ashiqs' songs are semi-improvised around common bases. Azerbaijan's ashiq art was included in the list of Intangible Cultural Heritage by the UNESCO on 30 September 2009. Since the mid-1960s, Western-influenced Azerbaijani pop music, in its various forms, that has been growing in popularity in Azerbaijan, while genres such as rock and hip hop are widely produced and enjoyed. Azerbaijani pop and Azerbaijani folk music arose with the international popularity of performers like Alim Qasimov, Rashid Behbudov, Vagif Mustafazadeh, Muslim Magomayev, Shovkat Alakbarova and Rubaba Muradova. Azerbaijan is an enthusiastic participant in the Eurovision Song Contest. Azerbaijan made its debut appearance at the 2008 Eurovision Song Contest. The country's entry gained third place in 2009 and fifth the following year. Ell and Nikki won the first place at the Eurovision Song Contest 2011 with the song "Running Scared", entitling Azerbaijan to host the contest in 2012, in Baku. They have qualified for every Grand Final up until the 2018 edition of the contest, entering with X My Heart by singer Aisel. There are dozens of Azerbaijani folk dances. They are performed at formal celebrations and the dancers wear national clothes like the Chokha, which is well-preserved within the national dances. Most dances have a very fast rhythm. Literature Among the medieval authors born within the territorial limits of modern Azerbaijani Republic was Persian poet and philosopher Nizami, called Ganjavi after his place of birth, Ganja, who was the author of the Khamsa ("The Quintuplet"), composed of five romantic poems, including "The Treasure of Mysteries", "Khosrow and Shīrīn", and "Leyli and Mejnūn". The earliest known figure in written Azerbaijani literature was Izzeddin Hasanoghlu, who composed a divan consisting of Persian and Azerbaijani ghazals. In Persian ghazals he used his pen-name, while his Azerbaijani ghazals were composed under his own name of Hasanoghlu. Classical literature in Azerbaijani was formed in the 14th century based on the various Early Middle Ages dialects of Tabriz and Shirvan. Among the poets of this period were Gazi Burhanaddin, Haqiqi (pen-name of Jahan Shah Qara Qoyunlu), and Habibi. The end of the 14th century was also the period of starting literary activity of Imadaddin Nasimi, one of the greatest Azerbaijani Hurufi mystical poets of the late 14th and early 15th centuries and one of the most prominent early divan masters in Turkic literary history, who also composed poetry in Persian and Arabic. The divan and ghazal styles were further developed by poets Qasem-e Anvar, Fuzuli and Khatai (pen-name of Safavid Shah Ismail I). The Book of Dede Korkut consists of two manuscripts copied in the 16th century, and was not written earlier than the 15th century. It is a collection of 12 stories reflecting the oral tradition of Oghuz nomads. The 16th-century poet, Muhammed Fuzuli produced his timeless philosophical and lyrical Qazals in Arabic, Persian, and Azerbaijani. Benefiting immensely from the fine literary traditions of his environment, and building upon the legacy of his predecessors, Fuzuli was destined to become the leading literary figure of his society. His major works include The Divan of Ghazals and The Qasidas. In the same century, Azerbaijani literature further flourished with the development of Ashik () poetic genre of bards. During the same period, under the pen-name of Khatāī ( for sinner) Shah Ismail I wrote about 1400 verses in Azerbaijani, which were later published as his Divan. A unique literary style known as qoshma ( for improvisation) was introduced in this period, and developed by Shah Ismail and later by his son and successor, Shah Tahmasp I. In the span of the 17th and 18th centuries, Fuzuli's unique genres as well Ashik poetry were taken up by prominent poets and writers such as Qovsi of Tabriz, Shah Abbas Sani, , Nishat, Molla Vali Vidadi, Molla Panah Vagif, Amani, Zafar and others. Along with Turks, Turkmens and Uzbeks, Azerbaijanis also celebrate the Epic of Koroglu (from for blind man's son), a legendary folk hero. Several documented versions of Koroglu epic remain at the Institute for Manuscripts of the National Academy of Sciences of Azerbaijan. Modern Azerbaijani literature in Azerbaijan is based on the Shirvani dialect mainly, while in Iran it is based on the Tabrizi one. The first newspaper in Azerbaijani, Akinchi was published in 1875. In the mid-19th century, it was taught in the schools of Baku, Ganja, Shaki, Tbilisi, and Yerevan. Since 1845, it was also taught in the University of Saint Petersburg in Russia. Folk art Azerbaijanis have a rich and distinctive culture, a major part of which is decorative and applied art. This art form is represented by a wide range of handicrafts, such as chasing, jeweling, engraving in metal, carving in wood, stone, bone, carpet-making, lasing, pattern weaving and printing, and knitting and embroidery. Each of these types of decorative art, evidence of the endowments of the Azerbaijan nation, is very much in favor here. Many interesting facts pertaining to the development of arts and crafts in Azerbaijan were reported by numerous merchants, travelers, and diplomats who had visited these places at different times. The Azerbaijani carpet is a traditional handmade textile of various sizes, with a dense texture and a pile or pile-less surface, whose patterns are characteristic of Azerbaijan's many carpet-making regions. In November 2010 the Azerbaijani carpet was proclaimed a Masterpiece of Intangible Heritage by UNESCO. Azerbaijan has been since ancient times known as a center of a large variety of crafts. The archeological dig on the territory of Azerbaijan testifies to the well-developed agriculture, stock raising, metalworking, pottery, ceramics, and carpet-weaving that date as far back as to the 2nd millennium BC. Archeological sites in Dashbulaq, Hasansu, Zayamchai, and Tovuzchai uncovered from the BTC pipeline have revealed early Iron Age artifacts. Azerbaijani carpets can be categorized under several large groups and a multitude of subgroups. Scientific research of the Azerbaijani carpet is connected with the name of Latif Karimov, a prominent scientist and artist. It was his classification that related the four large groups of carpets with the four geographical zones of Azerbaijan, Guba-Shirvan, Ganja-Kazakh, Karabakh and Tabriz. Cuisine The traditional cuisine is famous for an abundance of vegetables and greens used seasonally in the dishes. Fresh herbs, including mint, cilantro (coriander), dill, basil, parsley, tarragon, leeks, chives, thyme, marjoram, green onion, and watercress, are very popular and often accompany main dishes on the table. Climatic diversity and fertility of the land are reflected in the national dishes, which are based on fish from the Caspian Sea, local meat (mainly mutton and beef), and an abundance of seasonal vegetables and greens. Saffron-rice plov is the flagship food in Azerbaijan and black tea is the national beverage. Azerbaijanis often use traditional armudu (pear-shaped) glass as they have very strong tea culture. Popular traditional dishes include bozbash (lamb soup that exists in several regional varieties with the addition of different vegetables), qutab (fried turnover with a filling of greens or minced meat) and dushbara (sort of dumplings of dough filled with ground meat and flavor). Architecture Azerbaijani architecture typically combines elements of East and West. Azerbaijani architecture has heavy influences from Persian architecture. Many ancient architectural treasures such as the Maiden Tower and Palace of the Shirvanshahs in the Walled City of Baku survive in modern Azerbaijan. Entries submitted on the UNESCO World Heritage tentative list include the Ateshgah of Baku, Momine Khatun Mausoleum, Hirkan National Park, Binagadi asphalt lake, Lökbatan Mud Volcano, Shusha State Historical and Architectural Reserve, Baku Stage Mountain, Caspian Shore Defensive Constructions, Ordubad National Reserve and the Palace of Shaki Khans. Among other architectural treasures are Quadrangular Castle in Mardakan, Parigala in Yukhary Chardaglar, a number of bridges spanning the Aras River, and several mausoleums. In the 19th and early 20th centuries, little monumental architecture was created, but distinctive residences were built in Baku and elsewhere. Among the most recent architectural monuments, the Baku subways are noted for their lavish decor. The task for modern Azerbaijani architecture is diverse application of modern aesthetics, the search for an architect's own artistic style and inclusion of the existing historico-cultural environment. Major projects such as Heydar Aliyev Cultural Center, Flame Towers, Baku Crystal Hall, Baku White City and SOCAR Tower have transformed the country's skyline and promotes its contemporary identity. Visual art The Gamigaya Petroglyphs, which date back to the 1st to 4th millennium BC, are located in Azerbaijan's Ordubad District. They consist of some 1500 dislodged and carved rock paintings with images of deer, goats, bulls, dogs, snakes, birds, fantastic beings, and people, carriages, and various symbols were found on basalt rocks. Norwegian ethnographer and adventurer Thor Heyerdahl was convinced that people from the area went to Scandinavia in about 100 AD, took their boat building skills with them, and transmuted them into the Viking boats in Northern Europe. Over the centuries, Azerbaijani art has gone through many stylistic changes. Azerbaijani painting is traditionally characterized by a warmth of colour and light, as exemplified in the works of Azim Azimzade and Bahruz Kangarli, and a preoccupation with religious figures and cultural motifs. Azerbaijani painting enjoyed preeminence in Caucasus for hundreds of years, from the Romanesque and Ottoman periods, and through the Soviet and Baroque periods, the latter two of which saw fruition in Azerbaijan. Other notable artists who fall within these periods include Sattar Bahlulzade, Togrul Narimanbekov, Tahir Salahov, Alakbar Rezaguliyev, Mirza Gadim Iravani, Mikayil Abdullayev and Boyukagha Mirzazade. Cinema The film industry in Azerbaijan dates back to 1898. Azerbaijan was among the first countries involved in cinematography, with the apparatus first showing up in Baku. In 1919, during the Azerbaijan Democratic Republic, a documentary The Celebration of the Anniversary of Azerbaijani Independence was filmed on the first anniversary of Azerbaijan's independence from Russia, 27 May, and premiered in June 1919 at several theatres in Baku. After the Soviet power was established in 1920, Nariman Narimanov, Chairman of the Revolutionary Committee of Azerbaijan, signed a decree nationalizing Azerbaijan's cinema. This also influenced the creation of Azerbaijani animation. In 1991, after Azerbaijan gained its independence from the Soviet Union, the first Baku International Film Festival East-West was held in Baku. In December 2000, the former President of Azerbaijan, Heydar Aliyev, signed a decree proclaiming 2 August to be the professional holiday of filmmakers of Azerbaijan. Today Azerbaijani filmmakers are again dealing with issues similar to those faced by cinematographers prior to the establishment of the Soviet Union in 1920. Once again, both choices of content and sponsorship of films are largely left up to the initiative of the filmmaker. Television There are three state-owned television channels: AzTV, Idman TV and Medeniyyet TV. There is one public channel and 6 private channels: İctimai Television, Space TV, Lider TV, Azad Azerbaijan TV, , and ARB. Human rights The Constitution of Azerbaijan claims to guarantee freedom of speech, but this is denied in practice. After several years of decline in press and media freedom, in 2014, the media environment in Azerbaijan deteriorated rapidly under a governmental campaign to silence any opposition and criticism, even while the country led the Committee of Ministers of the Council of Europe (May–November 2014). Spurious legal charges and impunity in violence against journalists have remained the norm. All foreign broadcasts are banned in the country. According to the 2013 Freedom House Freedom of the Press report, Azerbaijan's press freedom status is "not free", and Azerbaijan ranks 177th out of 196 countries. Christianity is officially recognized. All religious communities are required to register to be allowed to meet, under the risk of imprisonment. This registration is often denied. "Racial discrimination contributes to the country's lack of religious freedom, since many of the Christians are ethnic Armenian or Russian, rather than Azeri Muslim." Radio Free Europe/Radio Liberty and Voice of America are banned in Azerbaijan. Discrimination against LGBT people in Azerbaijan is widespread. During the last few years, three journalists were killed and several prosecuted in trials described as unfair by international human rights organizations. Azerbaijan had the biggest number of journalists imprisoned in Europe in 2015, according to the Committee to Protect Journalists, and is the 5th most censored country in the world, ahead of Iran and China. Some critical journalists have been arrested for their coverage of the COVID-19 pandemic in Azerbaijan. A report by an Amnesty International researcher in October 2015 points to "...the severe deterioration of human rights in Azerbaijan over the past few years. Sadly Azerbaijan has been allowed to get away with unprecedented levels of repression and in the process almost wipe out its civil society". Amnesty's 2015/16 annual report on the country stated "... persecution of political dissent continued. Human rights organizations remained unable to resume their work. At least 18 prisoners of conscience remained in detention at the end of the year. Reprisals against independent journalists and activists persisted both in the country and abroad, while their family members also faced harassment and arrests. International human rights monitors were barred and expelled from the country. Reports of torture and other ill-treatment persisted. The Guardian reported in April 2017 that "Azerbaijan's ruling elite operated a secret $2.9bn (£2.2bn) scheme to pay prominent Europeans, buy luxury goods and launder money through a network of opaque British companies .... Leaked data shows that the Azerbaijani leadership, accused of serial human rights abuses, systemic corruption and rigging elections, made more than 16,000 covert payments from 2012 to 2014. Some of this money went to politicians and journalists, as part of an international lobbying operation to deflect criticism of Azerbaijan's president, Ilham Aliyev, and to promote a positive image of his oil-rich country." There was no suggestion that all recipients were aware of the source of the money as it arrived via a disguised route. Sport Freestyle wrestling has been traditionally regarded as Azerbaijan's national sport, in which Azerbaijan won up to fourteen medals, including four golds since joining the International Olympic Committee. Currently, the most popular sports include football and wrestling. Football is the most popular sport in Azerbaijan, and the Association of Football Federations of Azerbaijan with 9,122 registered players, is the largest sporting association in the country. The national football team of Azerbaijan demonstrates relatively low performance in the international arena compared to the nation football clubs. The most successful Azerbaijani football clubs are Neftçi, Qarabağ, and Gabala. In 2012, Neftchi Baku became the first Azerbaijani team to advance to the group stage of a European competition, beating APOEL of Cyprus 4–2 on aggregate in the play-off round of the 2012–13 UEFA Europa League. In 2014, Qarabağ became the second Azerbaijani club advancing to the group stage of UEFA Europa League. In 2017, after beating Copenhagen 2–2 (a) in the play-off round of the UEFA Champions League, Qarabağ became the first Azerbaijani club to reach the Group stage. Futsal is another popular sport in Azerbaijan. The Azerbaijan national futsal team reached fourth place in the 2010 UEFA Futsal Championship, while domestic club Araz Naxçivan clinched bronze medals at the 2009–10 UEFA Futsal Cup and 2013–14 UEFA Futsal Cup. Azerbaijan was the main sponsor of Spanish football club Atlético de Madrid during seasons 2013/2014 and 2014/2015, a partnership that the club described should 'promote the image of Azerbaijan in the world'. Azerbaijan is one of the traditional powerhouses of world chess, having hosted many international chess tournaments and competitions and became European Team Chess Championship winners in 2009, 2013 and 2017. Notable chess players from the country's chess schools that have made a great impact on the game include Teimour Radjabov, Shahriyar Mammadyarov, Vladimir Makogonov, Vugar Gashimov and former World Chess Champion Garry Kasparov. , country's home of Shamkir Chess a category 22 event and one of the highest rated tournaments of all time. Backgammon also plays a major role in Azerbaijani culture. The game is very popular in Azerbaijan and is widely played among the local public. There are also different variations of backgammon developed and analyzed by Azerbaijani experts. Azerbaijan Women's Volleyball Super League is one of the strongest women leagues in the world. Its women's national team came fourth at the 2005 European Championship. Over the last years, clubs like Rabita Baku and Azerrail Baku achieved great success at European cups. Azerbaijani volleyball players include likes of Valeriya Korotenko, Oksana Parkhomenko, Inessa Korkmaz, Natalya Mammadova and Alla Hasanova. Other Azerbaijani athletes are Namig Abdullayev, Toghrul Asgarov, Rovshan Bayramov, Sharif Sharifov, Mariya Stadnik and Farid Mansurov in wrestling, Nazim Huseynov, Elnur Mammadli, Elkhan Mammadov and Rustam Orujov in judo, Rafael Aghayev in karate, Magomedrasul Majidov and Aghasi Mammadov in boxing, Nizami Pashayev in Olympic weightlifting, Azad Asgarov in pankration, Eduard Mammadov in kickboxing, and K-1 fighter Zabit Samedov. Azerbaijan has a Formula One race-track, made in June 2012, and the country hosted its first Formula One Grand Prix on 19 June 2016 and the Azerbaijan Grand Prix in 2017, 2018, 2019, 2021 and 2022. Other annual sporting events held in the country are the Baku Cup tennis tournament and the Tour d'Azerbaïdjan cycling race. Azerbaijan hosted several major sport competitions since the late 2000s, including the 2013 F1 Powerboat World Championship, 2012 FIFA U-17 Women's World Cup, 2011 AIBA World Boxing Championships, 2010 European Wrestling Championships, 2009 Rhythmic Gymnastics European Championships, 2014 European Taekwondo Championships, 2014 Rhythmic Gymnastics European Championships, and 2016 World Chess Olympiad. On 8 December 2012, Baku was selected to host the 2015 European Games, the first to be held in the competition's history. Baku also hosted the fourth Islamic Solidarity Games in 2017 and the 2019 European Youth Summer Olympic Festival, and it is also one of the hosts of UEFA Euro 2020, which because of Covid-19 is being held in 2021.

https://en.wikipedia.org/wiki/Annual%20plant

Annual plant

An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. Description With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, because their seed-to-seed life cycle is only weeks and they spend most of the year as seeds to survive dry conditions. Cultivation In cultivation, many food plants are, or are grown as, annuals, including virtually all domesticated grains. Some perennials and biennials are grown in gardens as annuals for convenience, particularly if they are not considered cold hardy for the local climate. Carrot, celery and parsley are true biennials that are usually grown as annual crops for their edible roots, petioles and leaves, respectively. Tomato, sweet potato and bell pepper are tender perennials usually grown as annuals. Ornamental perennials commonly grown as annuals are impatiens, mirabilis, wax begonia, snapdragon, pelargonium, coleus and petunia. Examples of true annuals include corn, wheat, rice, lettuce, peas, watermelon, beans, zinnia and marigold. Summer Summer annuals sprout, flower, produce seed, and die, during the warmer months of the year. The lawn weed crabgrass is a summer annual. Winter Winter annuals germinate in autumn or winter, live through the winter, then bloom in winter or spring. The plants grow and bloom during the cool season when most other plants are dormant or other annuals are in seed form waiting for warmer weather to germinate. Winter annuals die after flowering and setting seed. The seeds germinate in the autumn or winter when the soil temperature is cool. Winter annuals typically grow low to the ground, where they are usually sheltered from the coldest nights by snow cover, and make use of warm periods in winter for growth when the snow melts. Some common winter annuals include henbit, deadnettle, chickweed, and winter cress. Winter annuals are important ecologically, as they provide vegetative cover that prevents soil erosion during winter and early spring when no other cover exists and they provide fresh vegetation for animals and birds that feed on them. Although they are often considered to be weeds in gardens, this viewpoint is not always necessary, as most of them die when the soil temperature warms up again in early to late spring when other plants are still dormant and have not yet leafed out. Even though they do not compete directly with cultivated plants, sometimes winter annuals are considered a pest in commercial agriculture, because they can be hosts for insect pests or fungal diseases (such as ovary smut, Microbotryum sp.) which attack crops being cultivated. The property that they prevent the soil from drying out can also be problematic for commercial agriculture. Molecular genetics In 2008, it was discovered that the inactivation of only two genes in one species of annual plant leads to its conversion into a perennial plant. Researchers deactivated the SOC1 and FUL genes (which control flowering time) of Arabidopsis thaliana. This switch established phenotypes common in perennial plants, such as wood formation.

https://en.wikipedia.org/wiki/Anthophyta

Anthophyta

The anthophytes are a grouping of plant taxa bearing flower-like reproductive structures. They were formerly thought to be a clade comprising plants bearing flower-like structures. The group contained the angiosperms - the extant flowering plants, such as roses and grasses - as well as the Gnetales and the extinct Bennettitales. Detailed morphological and molecular studies have shown that the group is not actually monophyletic, with proposed floral homologies of the gnetophytes and the angiosperms having evolved in parallel. This makes it easier to reconcile molecular clock data that suggests that the angiosperms diverged from the gymnosperms around 320-300 mya. Some more recent studies have used the word anthophyte to describe a group which includes the angiosperms and a variety of fossils (glossopterids, Pentoxylon, Bennettitales, and Caytonia), but not the Gnetales.

https://en.wikipedia.org/wiki/Alismatales

Alismatales

The Alismatales (alismatids) are an order of flowering plants including about 4,500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats. Description The Alismatales comprise herbaceous flowering plants of often aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. The flowers are usually arranged in inflorescences, and the mature seeds lack endosperm. Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface. There they can pollinate carpellate flowers floating on the surface via long pedicels. In others, pollination occurs underwater, where pollen may form elongated strands, increasing chance of success. Most aquatic species have a totally submerged juvenile phase, and flowers are either floating or emergent. Vegetation may be totally submersed, have floating leaves, or protrude from the water. Collectively, they are commonly known as "water plantain". Taxonomy The Alismatales contain about 165 genera in 13 families, with a cosmopolitan distribution. Phylogenetically, they are basal monocots, diverging early in evolution relative to the lilioid and commelinid monocot lineages. Together with the Acorales, the Alismatales are referred to informally as the alismatid monocots. Early systems The Cronquist system (1981) places the Alismatales in subclass Alismatidae, class Liliopsida [= monocotyledons] and includes only three families as shown: Alismataceae Butomaceae Limnocharitaceae Cronquist's subclass Alismatidae conformed fairly closely to the order Alismatales as defined by APG, minus the Araceae. The Dahlgren system places the Alismatales in the superorder Alismatanae in the subclass Liliidae [= monocotyledons] in the class Magnoliopsida [= angiosperms] with the following families included: Alismataceae Aponogetonaceae Butomaceae Hydrocharitaceae Limnocharitaceae In Tahktajan's classification (1997), the order Alismatales contains only the Alismataceae and Limnocharitaceae, making it equivalent to the Alismataceae as revised in APG-III. Other families included in the Alismatates as currently defined are here distributed among 10 additional orders, all of which are assigned, with the following exception, to the Subclass Alismatidae. Araceae in Tahktajan 1997 is assigned to the Arales and placed in the Subclass Aridae; Tofieldiaceae to the Melanthiales and placed in the Liliidae. Angiosperm Phylogeny Group The Angiosperm Phylogeny Group system (APG) of 1998 and APG II (2003) assigned the Alismatales to the monocots, which may be thought of as an unranked clade containing the families listed below. The biggest departure from earlier systems (see below) is the inclusion of family Araceae. By its inclusion, the order has grown enormously in number of species. The family Araceae alone accounts for about a hundred genera, totaling over two thousand species. The rest of the families together contain only about five hundred species, many of which are in very small families. The APG III system (2009) differs only in that the Limnocharitaceae are combined with the Alismataceae; it was also suggested that the genus Maundia (of the Juncaginaceae) could be separated into a monogeneric family, the Maundiaceae, but the authors noted that more study was necessary before the Maundiaceae could be recognized. order Alismatales sensu APG III family Alismataceae (including Limnocharitaceae) family Aponogetonaceae family Araceae family Butomaceae family Cymodoceaceae family Hydrocharitaceae family Juncaginaceae family Posidoniaceae family Potamogetonaceae family Ruppiaceae family Scheuchzeriaceae family Tofieldiaceae family Zosteraceae In APG IV (2016), it was decided that evidence was sufficient to elevate Maundia to family level as the monogeneric Maundiaceae. The authors considered including a number of the smaller orders within the Juncaginaceae, but an online survey of botanists and other users found little support for this "lumping" approach. Consequently, the family structure for APG IV is: family Alismataceae (including Limnocharitaceae) family Aponogetonaceae family Araceae family Butomaceae family Cymodoceaceae family Hydrocharitaceae family Juncaginaceae family Maundiaceae family Posidoniaceae family Potamogetonaceae family Ruppiaceae family Scheuchzeriaceae family Tofieldiaceae family Zosteraceae Phylogeny Cladogram showing the orders of monocots (Lilianae sensu Chase & Reveal) based on molecular phylogenetic evidence: References Further reading B.

https://en.wikipedia.org/wiki/Asterales

Asterales

Asterales () is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the Lobelia deckenii, the giant lobelia, and Dendrosenecio, giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosaccharide inulin, a nutrient storage molecule used instead of starch; and unique stamen morphology. The stamens are usually found around the style, either aggregated densely or fused into a tube, probably an adaptation in association with the plunger (brush; or secondary) pollination that is common among the families of the order, wherein pollen is collected and stored on the length of the pistil. Taxonomy The name and order Asterales is botanically venerable, dating back to at least 1926 in the Hutchinson system of plant taxonomy when it contained only five families, of which only two are retained in the APG III classification. Under the Cronquist system of taxonomic classification of flowering plants, Asteraceae was the only family in the group, but newer systems (such as APG II and APG III) have expanded it to 11. In the classification system of Rolf Dahlgren the Asterales were in the superorder Asteriflorae (also called Asteranae). The order Asterales currently includes 11 families, the largest of which are the Asteraceae, with about 25,000 species, and the Campanulaceae (bellflowers), with about 2,000 species. The remaining families count together for less than 1500 species. The two large families are cosmopolitan, with many of their species found in the Northern Hemisphere, and the smaller families are usually confined to Australia and the adjacent areas, or sometimes South America. Only the Asteraceae have composite flower heads; the other families do not, but share other characteristics such as storage of inulin that define the 11 families as more closely related to each other than to other plant families or orders such as the rosids. The phylogenetic tree according to APG III for the Campanulid clade is as below. Phylogeny Although most extant species of Asteraceae are herbaceous, the examination of the basal members in the family suggests that the common ancestor of the family was an arborescent plant, a tree or shrub, perhaps adapted to dry conditions, radiating from South America. Less can be said about the Asterales themselves with certainty, although since several families in Asterales contain trees, the ancestral member is most likely to have been a tree or shrub. Because all clades are represented in the Southern Hemisphere but many not in the Northern Hemisphere, it is natural to conjecture that there is a common southern origin to them. Asterales are angiosperms, flowering plants that appeared about 140 million years ago. The Asterales order probably originated in the Cretaceous (145 – 66 Mya) on the supercontinent Gondwana which broke up from 184 – 80 Mya, forming the area that is now Australia, South America, Africa, India and Antarctica. Asterales contain about 14% of eudicot diversity. From an analysis of relationships and diversities within the Asterales and with their superorders, estimates of the age of the beginning of the Asterales have been made, which range from 116 Mya to 82Mya. However few fossils have been found, of the Menyanthaceae-Asteraceae clade in the Oligocene, about 29 Mya. Fossil evidence of the Asterales is rare and belongs to rather recent epochs, so the precise estimation of the order's age is quite difficult. An Oligocene (34 – 23 Mya) pollen is known for Asteraceae and Goodeniaceae, and seeds from Oligocene and Miocene (23 – 5.3 Mya) are known for Menyanthaceae and Campanulaceae respectively. Biogeography The core Asterales are Stylidiaceae (six genera), APA clade (Alseuosmiaceae, Phellinaceae and Argophyllaceae, together seven genera), MGCA clade (Menyanthaceae, Goodeniaceae, Calyceraceae, in total twenty genera), and Asteraceae (about sixteen hundred genera). Other Asterales are Rousseaceae (four genera), Campanulaceae (eighty-four genera) and Pentaphragmataceae (one genus). All Asterales families are represented in the Southern Hemisphere; however, Asteraceae and Campanulaceae are cosmopolitan and Menyanthaceae nearly so. Uses The Asterales, by dint of being a super-set of the family Asteraceae, include some species grown for food, including the sunflower (Helianthus annuus), lettuce (Lactuca sativa) and chicory (Cichorium). Many are also used as spices and traditional medicines. Asterales are common plants and have many known uses. For example, pyrethrum (derived from Old World members of the genus Chrysanthemum) is a natural insecticide with minimal environmental impact. Wormwood, derived from a genus that includes the sagebrush, is used as a source of flavoring for absinthe, a bitter classical liquor of European origin. References Further reading W. S. Judd, C. S.

https://en.wikipedia.org/wiki/Allocution

Allocution

An allocution, or allocutus, is a formal statement made to the court by the defendant who has been found guilty prior to being sentenced. It is part of the criminal procedure in some jurisdictions using common law. Concept An allocution allows the defendant to explain why the sentence should be lenient. In plea bargains, an allocution may be required of the defendant. The defendant explicitly admits specifically and in detail the actions and their reasons in exchange for a reduced sentence. In principle, that removes any doubt as to the exact nature of the defendant's guilt in the matter. The term "allocution" is used generally only in jurisdictions in the United States, but there are vaguely similar processes in other common law countries. In many other jurisdictions, it is for the defense lawyer to mitigate on their client's behalf, and the defendant rarely has the opportunity to speak. The right of victims to speak at sentencing is also sometimes referred to as allocution. Australia In Australia, the term allocutus is used by the Clerk of Arraigns or another formal associate of the court. It is generally phrased as, "Prisoner at the Bar, you have been found Guilty by a jury of your peers of the offense of XYZ. Do you have anything to say as to why the sentence of this Court should not now be passed upon you?" The defense counsel will then make a plea in mitigation (also called submissions on penalty) in an attempt to mitigate the relative seriousness of the offense and heavily refer to and rely upon the defendant's previous good character and good works, if any. The right to make a plea in mitigation is absolute. If a judge or magistrate refuses to hear such a plea or does not properly consider it, the sentence can be overturned on appeal. United States In most of the United States, defendants are allowed the opportunity to allocute before a sentence is passed. Some jurisdictions hold that as an absolute right. In its absence, a sentence but not the conviction may be overturned, resulting in the need for a new sentencing hearing. In the federal system, Federal Rules of Criminal Procedure 32(i)(4) provides that the court must "address the defendant personally in order to permit the defendant to speak or present any information to mitigate the sentence." The federal public defender recommends that defendants speak in terms of how a lenient sentence will be sufficient but not greater than necessary to comply with the statutory directives set forth in .

Aquarius (constellation)

Aquarius is an equatorial constellation of the zodiac, between Capricornus and Pisces. Its name is Latin for "water-carrier" or "cup-carrier", and its old astronomical symbol is (♒︎), a representation of water. Aquarius is one of the oldest of the recognized constellations along the zodiac (the Sun's apparent path). It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is found in a region often called the Sea due to its profusion of constellations with watery associations such as Cetus the whale, Pisces the fish, and Eridanus the river. At apparent magnitude 2.9, Beta Aquarii is the brightest star in the constellation. History and mythology Aquarius is identified as "The Great One" in the Babylonian star catalogues and represents the god Ea himself, who is commonly depicted holding an overflowing vase. The Babylonian star-figure appears on entitlement stones and cylinder seals from the second millennium. It contained the winter solstice in the Early Bronze Age. In Old Babylonian astronomy, Ea was the ruler of the southernmost quarter of the Sun's path, the "Way of Ea", corresponding to the period of 45 days on either side of winter solstice. Aquarius was also associated with the destructive floods that the Babylonians regularly experienced, and thus was negatively connoted. In Ancient Egypt astronomy, Aquarius was associated with the annual flood of the Nile; the banks were said to flood when Aquarius put his jar into the river, beginning spring. In the Greek tradition, the constellation came to be represented simply as a single vase from which a stream poured down to Piscis Austrinus. The name in the Hindu zodiac is likewise kumbha "water-pitcher". In Greek mythology, Aquarius is sometimes associated with Deucalion, the son of Prometheus who built a ship with his wife Pyrrha to survive an imminent flood. They sailed for nine days before washing ashore on Mount Parnassus. Aquarius is also sometimes identified with beautiful Ganymede, a youth in Greek mythology and the son of Trojan king Tros, who was taken to Mount Olympus by Zeus to act as cup-carrier to the gods. Neighboring Aquila represents the eagle, under Zeus' command, that snatched the young boy; some versions of the myth indicate that the eagle was in fact Zeus transformed. An alternative version of the tale recounts Ganymede's kidnapping by the goddess of the dawn, Eos, motivated by her affection for young men; Zeus then stole him from Eos and employed him as cup-bearer. Yet another figure associated with the water bearer is Cecrops I, a king of Athens who sacrificed water instead of wine to the gods. Depictions In the first century, Ptolemy's Almagest established the common Western depiction of Aquarius. His water jar, an asterism itself, consists of Gamma, Pi, Eta, and Zeta Aquarii; it pours water in a stream of more than 20 stars terminating with Fomalhaut, now assigned solely to Piscis Austrinus. The water bearer's head is represented by 5th magnitude 25 Aquarii while his left shoulder is Beta Aquarii; his right shoulder and forearm are represented by Alpha and Gamma Aquarii respectively. In Eastern astronomy In Chinese astronomy, the stream of water flowing from the Water Jar was depicted as the "Army of Yu-Lin" (Yu-lim-kiun or Yulinjun, Hanzi: 羽林君). The name "Yu-lin" means "feathers and forests", referring to the numerous light-footed soldiers from the northern reaches of the empire represented by these faint stars. The constellation's stars were the most numerous of any Chinese constellation, numbering 45, the majority of which were located in modern Aquarius. The celestial army was protected by the wall Leibizhen (垒壁阵), which counted Iota, Lambda, Phi, and Sigma Aquarii among its 12 stars. 88, 89, and 98 Aquarii represent Fou-youe, the axes used as weapons and for hostage executions. Also in Aquarius is Loui-pi-tchin, the ramparts that stretch from 29 and 27 Piscium and 33 and 30 Aquarii through Phi, Lambda, Sigma, and Iota Aquarii to Delta, Gamma, Kappa, and Epsilon Capricorni. Near the border with Cetus, the axe Fuyue was represented by three stars; its position is disputed and may have instead been located in Sculptor. Tienliecheng also has a disputed position; the 13-star castle replete with ramparts may have possessed Nu and Xi Aquarii but may instead have been located south in Piscis Austrinus. The Water Jar asterism was seen to the ancient Chinese as the tomb, Fenmu. Nearby, the emperors' mausoleum Xiuliang stood, demarcated by Kappa Aquarii and three other collinear stars. Ku ("crying") and Qi ("weeping"), each composed of two stars, were located in the same region. Three of the Chinese lunar mansions shared their name with constellations. Nu, also the name for the 10th lunar mansion, was a handmaiden represented by Epsilon, Mu, 3, and 4 Aquarii. The 11th lunar mansion shared its name with the constellation Xu ("emptiness"), formed by Beta Aquarii and Alpha Equulei; it represented a bleak place associated with death and funerals. Wei, the rooftop and 12th lunar mansion, was a V-shaped constellation formed by Alpha Aquarii, Theta Pegasi, and Epsilon Pegasi; it shared its name with two other Chinese constellations, in modern-day Scorpius and Aries. Features Stars Despite both its prominent position on the zodiac and its large size, Aquarius has no particularly bright stars, its four brightest stars being less than magnitude 2. However, recent research has shown that there are several stars lying within its borders that possess planetary systems. The two brightest stars, Alpha and Beta Aquarii, are luminous yellow supergiants, of spectral types G0Ib and G2Ib respectively, that were once hot blue-white B-class main sequence stars 5 to 9 times as massive as the Sun. The two are also moving through space perpendicular to the plane of the Milky Way. Just shading Alpha, Beta Aquarii is the brightest star in Aquarius with an apparent magnitude of 2.91. It also has the proper name of Sadalsuud. Having cooled and swollen to around 50 times the Sun's diameter, it is around 2200 times as luminous as the Sun. It is around 6.4 times as massive as the Sun and around 56 million years old. Sadalsuud is 540 ± 20 light-years from Earth. Alpha Aquarii, also known as Sadalmelik, has an apparent magnitude of 2.94. It is 520 ± 20 light-years distant from Earth, and is around 6.5 times as massive as the Sun and 3000 times as luminous. It is 53 million years old. γ Aquarii, also called Sadachbia, is a white main sequence star of spectral type star of spectral type A0V that is between 158 and 315 million years old and is around two and a half times the Sun's mass, and double its radius. Of magnitude 3.85, it is 164 ± 9 light years away. It has a luminosity of . The name Sadachbia comes from the Arabic for "lucky stars of the tents", sa'd al-akhbiya. δ Aquarii, also known as Skat or Scheat is a blue-white A2 spectral type star of apparent magnitude 3.27 and luminosity of . ε Aquarii, also known as Albali, is a blue-white A1 spectral type star with an apparent magnitude of 3.77, an absolute magnitude of 1.2, and a luminosity of . ζ Aquarii is an F2 spectral type double star; both stars are white. Overall, it appears to be of magnitude 3.6 and luminosity of . The primary has a magnitude of 4.53 and the secondary a magnitude of 4.31, but both have an absolute magnitude of 0.6. Its orbital period is 760 years; the two components are currently moving farther apart. θ Aquarii, sometimes called Ancha, is a G8 spectral type star with an apparent magnitude of 4.16 and an absolute magnitude of 1.4. κ Aquarii, also called Situla, has an apparent magnitude of 5.03. λ Aquarii, also called Hudoor or Ekchusis, is an M2 spectral type star of magnitude 3.74 and luminosity of . ξ Aquarii, also called Bunda, is an A7 spectral type star with an apparent magnitude of 4.69 and an absolute magnitude of 2.4. π Aquarii, also called Seat, is a B0 spectral type star with an apparent magnitude of 4.66 and an absolute magnitude of −4.1. Planetary systems Twelve exoplanet systems have been found in Aquarius as of 2013. Gliese 876, one of the nearest stars to Earth at a distance of 15 light-years, was the first red dwarf star to be found to possess a planetary system. It is orbited by four planets, including one terrestrial planet 6.6 times the mass of Earth. The planets vary in orbital period from 2 days to 124 days. 91 Aquarii is an orange giant star orbited by one planet, 91 Aquarii b. The planet's mass is 2.9 times the mass of Jupiter, and its orbital period is 182 days. Gliese 849 is a red dwarf star orbited by the first known long-period Jupiter-like planet, Gliese 849 b. The planet's mass is 0.99 times that of Jupiter and its orbital period is 1,852 days. There are also less-prominent systems in Aquarius. WASP-6, a type G8 star of magnitude 12.4, is host to one exoplanet, WASP-6 b. The star is 307 parsecs from Earth and has a mass of 0.888 solar masses and a radius of 0.87 solar radii. WASP-6 b was discovered in 2008 by the transit method. It orbits its parent star every 3.36 days at a distance of 0.042 astronomical units (AU). It is 0.503 Jupiter masses but has a proportionally larger radius of 1.224 Jupiter radii. HD 206610, a K0 star located 194 parsecs from Earth, is host to one planet, HD 206610 b. The host star is larger than the Sun; more massive at 1.56 solar masses and larger at 6.1 solar radii. The planet was discovered by the radial velocity method in 2010 and has a mass of 2.2 Jupiter masses. It orbits every 610 days at a distance of 1.68 AU. Much closer to its sun is WASP-47 b, which orbits every 4.15 days only 0.052 AU from its sun, yellow dwarf (G9V) WASP-47. WASP-47 is close in size to the Sun, having a radius of 1.15 solar radii and a mass even closer at 1.08 solar masses. WASP-47 b was discovered in 2011 by the transit method, like WASP-6 b. It is slightly larger than Jupiter with a mass of 1.14 Jupiter masses and a radius of 1.15 Jupiter masses. There are several more single-planet systems in Aquarius. HD 210277, a magnitude 6.63 yellow star located 21.29 parsecs from Earth, is host to one known planet: HD 210277 b. The 1.23 Jupiter mass planet orbits at nearly the same distance as Earth orbits the Sun1.1 AU, though its orbital period is significantly longer at around 442 days. HD 210277 b was discovered earlier than most of the other planets in Aquarius, detected by the radial velocity method in 1998. The star it orbits resembles the Sun beyond their similar spectral class; it has a radius of 1.1 solar radii and a mass of 1.09 solar masses. HD 212771 b, a larger planet at 2.3 Jupiter masses, orbits host star HD 212771 at a distance of 1.22 AU. The star itself, barely below the threshold of naked-eye visibility at magnitude 7.6, is a G8IV (yellow subgiant) star located 131 parsecs from Earth. Though it has a similar mass to the Sun1.15 solar massesit is significantly less dense with its radius of 5 solar radii. Its lone planet was discovered in 2010 by the radial velocity method, like several other exoplanets in the constellation. As of 2013, there were only two known multiple-planet systems within the bounds of Aquarius: the Gliese 876 and HD 215152 systems. The former is quite prominent; the latter has only two planets and has a host star farther away at 21.5 parsecs. The HD 215152 system consists of the planets HD 215152 b and HD 215152 c orbiting their K0-type, magnitude 8.13 sun. Both discovered in 2011 by the radial velocity method, the two tiny planets orbit very close to their host star. HD 215152 c is the larger at 0.0097 Jupiter masses (still significantly larger than the Earth, which weighs in at 0.00315 Jupiter masses); its smaller sibling is barely smaller at 0.0087 Jupiter masses. The error in the mass measurements (0.0032 and respectively) is large enough to make this discrepancy statistically insignificant. HD 215152 c also orbits further from the star than HD 215152 b, 0.0852 AU compared to 0.0652. On 23 February 2017, NASA announced that ultracool dwarf star TRAPPIST-1 in Aquarius has seven Earth-like rocky planets. Of these, as many as four may lie within the system's habitable zone, and may have liquid water on their surfaces. The discovery of the TRAPPIST-1 system is seen by astronomers as a significant step toward finding life beyond Earth. Deep sky objects Because of its position away from the galactic plane, the majority of deep-sky objects in Aquarius are galaxies, globular clusters, and planetary nebulae. Aquarius contains three deep sky objects that are in the Messier catalog: the globular clusters Messier 2, Messier 72, and the asterism Messier 73. While M73 was originally catalogued as a sparsely populated open cluster, modern analysis indicates the 6 main stars are not close enough together to fit this definition, reclassifying M73 as an asterism. Two well-known planetary nebulae are also located in Aquarius: the Saturn Nebula (NGC 7009), to the southeast of μ Aquarii; and the famous Helix Nebula (NGC 7293), southwest of δ Aquarii. M2, also catalogued as NGC 7089, is a rich globular cluster located approximately 37,000 light-years from Earth. At magnitude 6.5, it is viewable in small-aperture instruments, but a 100 mm aperture telescope is needed to resolve any stars. M72, also catalogued as NGC 6981, is a small 9th magnitude globular cluster located approximately 56,000 light-years from Earth. M73, also catalogued as NGC 6994, is an open cluster with highly disputed status. Aquarius is also home to several planetary nebulae. NGC 7009, also known as the Saturn Nebula, is an 8th magnitude planetary nebula located 3,000 light-years from Earth. It was given its moniker by the 19th century astronomer Lord Rosse for its resemblance to the planet Saturn in a telescope; it has faint protrusions on either side that resemble Saturn's rings. It appears blue-green in a telescope and has a central star of magnitude 11.3. Compared to the Helix Nebula, another planetary nebula in Aquarius, it is quite small. NGC 7293, also known as the Helix Nebula, is the closest planetary nebula to Earth at a distance of 650 light-years. It covers 0.25 square degrees, making it also the largest planetary nebula as seen from Earth. However, because it is so large, it is only viewable as a very faint object, though it has a fairly high integrated magnitude of 6.0. One of the visible galaxies in Aquarius is NGC 7727, of particular interest for amateur astronomers who wish to discover or observe supernovae. A spiral galaxy (type S), it has an integrated magnitude of 10.7 and is 3 by 3 arcseconds. NGC 7252 is a tangle of stars resulting from the collision of two large galaxies and is known as the Atoms-for-Peace galaxy because of its resemblance to a cartoon atom. Meteor showers There are three major meteor showers with radiants in Aquarius: the Eta Aquariids, the Delta Aquariids, and the Iota Aquariids. The Eta Aquariids are the strongest meteor shower radiating from Aquarius. It peaks between 5 and 6 May with a rate of approximately 35 meteors per hour. Originally discovered by Chinese astronomers in 401, Eta Aquariids can be seen coming from the Water Jar beginning on 21 April and as late as 12 May. The parent body of the shower is Halley's Comet, a periodic comet. Fireballs are common shortly after the peak, approximately between 9 May and 11 May. The normal meteors appear to have yellow trails. The Delta Aquariids is a double radiant meteor shower that peaks first on 29 July and second on 6 August. The first radiant is located in the south of the constellation, while the second radiant is located in the northern circlet of Pisces asterism. The southern radiant's peak rate is about 20 meteors per hour, while the northern radiant's peak rate is about 10 meteors per hour. The Iota Aquariids is a fairly weak meteor shower that peaks on 6 August, with a rate of approximately 8 meteors per hour. Astrology , the Sun appears in the constellation Aquarius from 16 February to 12 March. In tropical astrology, the Sun is considered to be in the sign Aquarius from 20 January to 19 February, and in sidereal astrology, from 15 February to 14 March. Aquarius is also associated with the Age of Aquarius, a concept popular in 1960s counterculture. Despite this prominence, the Age of Aquarius will not dawn until the year 2597, as an astrological age does not begin until the Sun is in a particular constellation on the vernal equinox.

https://en.wikipedia.org/wiki/Altaic%20languages

Altaic languages

Altaic () is a controversial proposed language family that would include the Turkic, Mongolic and Tungusic language families and possibly also the Japonic and Koreanic languages. Speakers of these languages are currently scattered over most of Asia north of 35° N and in some eastern parts of Europe, extending in longitude from Turkey to Japan. The group is named after the Altai mountain range in the center of Asia. The hypothetical language family has long been rejected by most comparative linguists, although it continues to be supported by a small but stable scholarly minority. The research on their supposedly common linguistics origin has inspired various comparative studies on the folklore and mythology among the Turks, Proto-Mongols and Tungus people. The Altaic family was first proposed in the 18th century. It was widely accepted until the 1960s and is still listed in many encyclopedias and handbooks. Since the 1950s, many comparative linguists have rejected the proposal, after supposed cognates were found not to be valid, hypothesized sound shifts were not found, and Turkic and Mongolic languages were found to be converging rather than diverging over the centuries. Opponents of the theory proposed that the similarities are due to mutual linguistic influences between the groups concerned. Modern supporters of Altaic acknowledge that many shared features are the result of contact and convergence and thus cannot be taken as evidence for a genetic relationship, but they nevertheless argue that a core of existing correspondences goes back to a common ancestor. The original hypothesis unified only the Turkic, Mongolian, and Tungusic groups. Later proposals to include the Korean and Japanese languages into a "Macro-Altaic" family have always been controversial. The original proposal was sometimes called "Micro-Altaic" by retronymy. Most proponents of Altaic continue to support the inclusion of Korean, but fewer do for Japanese. Some proposals also included Ainuic but this is not widely accepted even among Altaicists themselves. A common ancestral Proto-Altaic language for the "Macro" family has been tentatively reconstructed by Sergei Starostin and others. Micro-Altaic includes about 66 living languages, to which Macro-Altaic would add Korean, Jeju, Japanese, and the Ryukyuan languages, for a total of about 74 (depending on what is considered a language and what is considered a dialect). These numbers do not include earlier states of languages, such as Middle Mongol, Old Korean, or Old Japanese. Earliest attestations The earliest attested expressions in Proto-Turkic are recorded in various Chinese sources. Anna Dybo identifies in Shizi (330 BCE) and the Book of Han (111 CE) several dozen Proto-Turkic exotisms in Chinese Han transcriptions. Lanhai Wei and Hui Li reconstruct the name of the Xiōngnú ruling house as PT *Alayundluğ /alajuntˈluγ/ 'piebald horse clan.' The earliest known texts in a Turkic language are the Orkhon inscriptions, 720–735 AD. They were deciphered in 1893 by the Danish linguist Vilhelm Thomsen in a scholarly race with his rival, the German–Russian linguist Wilhelm Radloff. However, Radloff was the first to publish the inscriptions. The first Tungusic language to be attested is Jurchen, the language of the ancestors of the Manchus. A writing system for it was devised in 1119 AD and an inscription using this system is known from 1185 (see List of Jurchen inscriptions). The earliest Mongolic language of which we have written evidence is known as Middle Mongol. It is first attested by an inscription dated to 1224 or 1225 AD, the Stele of Yisüngge, and by the Secret History of the Mongols, written in 1228 (see Mongolic languages). The earliest Para-Mongolic text is the Memorial for Yelü Yanning, written in the Khitan large script and dated to 986 AD. However, the Inscription of Hüis Tolgoi, discovered in 1975 and analysed as being in an early form of Mongolic, has been dated to 604-620 AD. The Bugut inscription dates back to 584 AD. Japanese is first attested in the form of names contained in a few short inscriptions in Classical Chinese from the 5th century AD, such as found on the Inariyama Sword. The first substantial text in Japanese, however, is the Kojiki, which dates from 712 AD. It is followed by the Nihon shoki, completed in 720, and then by the Man'yōshū, which dates from c. 771–785, but includes material that is from about 400 years earlier. The most important text for the study of early Korean is the Hyangga, a collection of 25 poems, of which some go back to the Three Kingdoms period (57 BC–668 AD), but are preserved in an orthography that only goes back to the 9th century AD. Korean is copiously attested from the mid-15th century on in the phonetically precise Hangul system of writing. History of the Altaic family concept Origins The earliest known reference to a unified language group of Turkic, Mongolic and Tungusic languages is from the 1692 work of Nicolaes Witsen which may be based on a 1661 work of Abu al-Ghazi Bahadur Genealogy of the Turks. A proposed grouping of the Turkic, Mongolic, and Tungusic languages was published in 1730 by Philip Johan von Strahlenberg, a Swedish officer who traveled in the eastern Russian Empire while a prisoner of war after the Great Northern War. However, he may not have intended to imply a closer relationship among those languages. Uralo-Altaic hypothesis In 1844, the Finnish philologist Matthias Castrén proposed a broader grouping which later came to be called the Ural–Altaic family, which included Turkic, Mongolian, and Manchu-Tungus (=Tungusic) as an "Altaic" branch, and also the Finno-Ugric and Samoyedic languages as the "Uralic" branch (though Castrén himself used the terms "Tataric" and "Chudic"). The name "Altaic" referred to the Altai Mountains in East-Central Asia, which are approximately the center of the geographic range of the three main families. The name "Uralic" referred to the Ural Mountains. While the Ural-Altaic family hypothesis can still be found in some encyclopedias, atlases, and similar general references, since the 1960s it has been heavily criticized. Even linguists who accept the basic Altaic family, such as Sergei Starostin, completely discard the inclusion of the "Uralic" branch. The term continues to be used for the central Eurasian typological, grammatical and lexical convergence zone. Indeed, "Ural-Altaic" may be preferable to "Altaic" in this sense. For example, Juha Janhunen states that "speaking of 'Altaic' instead of 'Ural-Altaic' is a misconception, for there are no areal or typological features that are specific to 'Altaic' without Uralic." Korean and Japanese languages In 1857, the Austrian scholar Anton Boller suggested adding Japanese to the Ural–Altaic family. In the 1920s, G.J. Ramstedt and E.D. Polivanov advocated the inclusion of Korean. Decades later, in his 1952 book, Ramstedt rejected the Ural–Altaic hypothesis but again included Korean in Altaic, an inclusion followed by most leading Altaicists (supporters of the theory) to date. His book contained the first comprehensive attempt to identify regular correspondences among the sound systems within the Altaic language families. In 1960, Nicholas Poppe published what was in effect a heavily revised version of Ramstedt's volume on phonology that has since set the standard in Altaic studies. Poppe considered the issue of the relationship of Korean to Turkic-Mongolic-Tungusic not settled. In his view, there were three possibilities: (1) Korean did not belong with the other three genealogically, but had been influenced by an Altaic substratum; (2) Korean was related to the other three at the same level they were related to each other; (3) Korean had split off from the other three before they underwent a series of characteristic changes. Roy Andrew Miller's 1971 book Japanese and the Other Altaic Languages convinced most Altaicists that Japanese also belonged to Altaic. Since then, the "Macro-Altaic" has been generally assumed to include Turkic, Mongolic, Tungusic, Korean, and Japanese. In 1990, Unger advocated a family consisting of Tungusic, Korean, and Japonic languages, but not Turkic or Mongolic. However, many linguists dispute the alleged affinities of Korean and Japanese to the other three groups. Some authors instead tried to connect Japanese to the Austronesian languages. In 2017, Martine Robbeets proposed that Japanese (and possibly Korean) originated as a hybrid language. She proposed that the ancestral home of the Turkic, Mongolic, and Tungusic languages was somewhere in northwestern Manchuria. A group of those proto-Altaic ("Transeurasian") speakers would have migrated south into the modern Liaoning province, where they would have been mostly assimilated by an agricultural community with an Austronesian-like language. The fusion of the two languages would have resulted in proto-Japanese and proto-Korean. In a typological study that does not directly evaluate the validity of the Altaic hypothesis, Yurayong and Szeto (2020) discuss for Koreanic and Japonic the stages of convergence to the Altaic typological model and subsequent divergence from that model, which resulted in the present typological similarity between Koreanic and Japonic. They state that both are "still so different from the Core Altaic languages that we can even speak of an independent Japanese-Korean type of grammar. Given also that there is neither a strong proof of common Proto-Altaic lexical items nor solid regular sound correspondences but, rather, only lexical and structural borrowings between languages of the Altaic typology, our results indirectly speak in favour of a “Paleo-Asiatic” origin of the Japonic and Koreanic languages." The Ainu language In 1962, John C. Street proposed an alternative classification, with Turkic-Mongolic-Tungusic in one grouping and Korean-Japanese-Ainu in another, joined in what he designated as the "North Asiatic" family. The inclusion of Ainu was adopted also by James Patrie in 1982. The Turkic-Mongolic-Tungusic and Korean-Japanese-Ainu groupings were also posited in 2000–2002 by Joseph Greenberg. However, he treated them as independent members of a larger family, which he termed Eurasiatic. The inclusion of Ainu is not widely accepted by Altaicists. In fact, no convincing genealogical relationship between Ainu and any other language family has been demonstrated, and it is generally regarded as a language isolate. Early criticism and rejection Starting in the late 1950s, some linguists became increasingly critical of even the minimal Altaic family hypothesis, disputing the alleged evidence of genetic connection between Turkic, Mongolic and Tungusic languages. Among the earlier critics were Gerard Clauson (1956), Gerhard Doerfer (1963), and Alexander Shcherbak. They claimed that the words and features shared by Turkic, Mongolic, and Tungusic languages were for the most part borrowings and that the rest could be attributed to chance resemblances. In 1988, Doerfer again rejected all the genetic claims over these major groups. Modern controversy A major continuing supporter of the Altaic hypothesis has been Sergei Starostin, who published a comparative lexical analysis of the Altaic languages in 1991. He concluded that the analysis supported the Altaic grouping, although it was "older than most other language families in Eurasia, such as Indo-European or Finno-Ugric, and this is the reason why the modern Altaic languages preserve few common elements". In 1991 and again in 1996, Roy Miller defended the Altaic hypothesis and claimed that the criticisms of Clauson and Doerfer apply exclusively to the lexical correspondences, whereas the most pressing evidence for the theory is the similarities in verbal morphology. In 2003, Claus Schönig published a critical overview of the history of the Altaic hypothesis up to that time, siding with the earlier criticisms of Clauson, Doerfer, and Shcherbak. In 2003, Starostin, Anna Dybo and Oleg Mudrak published the Etymological Dictionary of the Altaic Languages, which expanded the 1991 lexical lists and added other phonological and grammatical arguments. Starostin's book was criticized by Stefan Georg in 2004 and 2005, and by Alexander Vovin in 2005. Other defenses of the theory, in response to the criticisms of Georg and Vovin, were published by Starostin in 2005, Blažek in 2006, Robbeets in 2007, and Dybo and G. Starostin in 2008. In 2010, Lars Johanson echoed Miller's 1996 rebuttal to the critics, and called for a muting of the polemic. List of supporters and critics of the Altaic hypothesis The list below comprises linguists who have worked specifically on the Altaic problem since the publication of the first volume of Ramstedt's Einführung in 1952.

Agnostic, proponent of a "Transeurasian" verbal morphology not necessarily genealogically linked. "Transeurasian" Renaming In Robbeets and Johanson (2010), there was a proposal to replace the name "Altaic" with the name "Transeurasian". While "Altaic" has sometimes included Japonic, Koreanic, and other languages or families, but only on the consideration of particular authors, "Transeurasian" was specifically intended to always include Turkic, Mongolic, Tungusic, Japonic, and Koreanic. Robbeets and Johanson gave as their reasoning for the new term: 1) to avoid confusion between the different uses of Altaic as to which group of languages is included, 2) to reduce the counterproductive polarization between "Pro-Altaists" and "Anti-Altaists"; 3) to broaden the applicability of the term because the suffix -ic implies affinity while -an leaves room for an areal hypothesis; and 4) to eliminate the reference to the Altai mountains as a potential homeland. In Robbeets and Savelyev, ed. (2020) there was a concerted effort to distinguish "Altaic" as a subgroup of "Transeurasian" consisting only of Turkic, Mongolic, and Tungusic, while retaining "Transeurasian" as "Altaic" plus Japonic and Koreanic. Arguments For the Altaic grouping Phonological and grammatical features The original arguments for grouping the "micro-Altaic" languages within a Uralo-Altaic family were based on such shared features as vowel harmony and agglutination. According to Roy Miller, the most pressing evidence for the theory is the similarities in verbal morphology. The Etymological Dictionary by Starostin and others (2003) proposes a set of sound change laws that would explain the evolution from Proto-Altaic to the descendant languages. For example, although most of today's Altaic languages have vowel harmony, Proto-Altaic as reconstructed by them lacked it; instead, various vowel assimilations between the first and second syllables of words occurred in Turkic, Mongolic, Tungusic, Korean, and Japonic. They also included a number of grammatical correspondences between the languages. Shared lexicon Starostin claimed in 1991 that the members of the proposed Altaic group shared about 15–20% of apparent cognates within a 110-word Swadesh-Yakhontov list; in particular, Turkic–Mongolic 20%, Turkic–Tungusic 18%, Turkic–Korean 17%, Mongolic–Tungusic 22%, Mongolic–Korean 16%, and Tungusic–Korean 21%. The 2003 Etymological Dictionary includes a list of 2,800 proposed cognate sets, as well as a few important changes to the reconstruction of Proto-Altaic. The authors tried hard to distinguish loans between Turkic and Mongolic and between Mongolic and Tungusic from cognates; and suggest words that occur in Turkic and Tungusic but not in Mongolic. All other combinations between the five branches also occur in the book. It lists 144 items of shared basic vocabulary, including words for such items as 'eye', 'ear', 'neck', 'bone', 'blood', 'water', 'stone', 'sun', and 'two'. Robbeets and Bouckaert (2018) use Bayesian phylolinguistic methods to argue for the coherence of the "narrow" Altaic languages (Turkic, Mongolic, and Tungusic) together with Japonic and Koreanic, which they refer to as the Transeurasian languages. Their results include the following phylogenetic tree: Martine Robbeets (2020) argues that early Transeurasian speakers were originally agriculturalists in northeastern China, only becoming pastoralists later on. Some lexical reconstructions of agricultural terms by Robbeets (2020) are listed below.

Proto-Austronesian *Semay ‘cooked rice’ Against the grouping Weakness of lexical and typological data According to G. Clauson (1956), G. Doerfer (1963), and A. Shcherbak (1963), many of the typological features of the supposed Altaic languages, particularly agglutinative strongly suffixing morphology and subject–object–verb (SOV) word order, often occur together in languages. Those critics also argued that the words and features shared by Turkic, Mongolic, and Tungusic languages were for the most part borrowings and that the rest could be attributed to chance resemblances. They noted that there was little vocabulary shared by Turkic and Tungusic languages, though more shared with Mongolic languages. They reasoned that, if all three families had a common ancestor, we should expect losses to happen at random, and not only at the geographical margins of the family; and that the observed pattern is consistent with borrowing. According to C. Schönig (2003), after accounting for areal effects, the shared lexicon that could have a common genetic origin was reduced to a small number of monosyllabic lexical roots, including the personal pronouns and a few other deictic and auxiliary items, whose sharing could be explained in other ways; not the kind of sharing expected in cases of genetic relationship. The Sprachbund hypothesis Instead of a common genetic origin, Clauson, Doerfer, and Shcherbak proposed (in 1956–1966) that Turkic, Mongolic, and Tungusic languages form a Sprachbund: a set of languages with similarities due to convergence through intensive borrowing and long contact, rather than common origin. Asya Pereltsvaig further observed in 2011 that, in general, genetically related languages and families tend to diverge over time: the earlier forms are more similar than modern forms. However, she claims that an analysis of the earliest written records of Mongolic and Turkic languages shows the opposite, suggesting that they do not share a common traceable ancestor, but rather have become more similar through language contact and areal effects. Hypothesis about the original homeland The prehistory of the peoples speaking the "Altaic" languages is largely unknown. Whereas for certain other language families, such as the speakers of Indo-European, Uralic, and Austronesian, it is possible to frame substantial hypotheses, in the case of the proposed Altaic family much remains to be done. Some scholars have hypothesised a possible Uralic and Altaic homeland in the Central Asian steppes. Chaubey and van Driem propose that the dispersal of ancient Altaic language communities is reflected by the early Holocene dissemination of haplogroup C2 (M217): "If the paternal lineage C2 (M217) is correlated with Altaic linguistic affinity, as appears to be the case for Turkic, Mongolic and Tungusic, then Japanese is no Father Tongue, and neither is Korean. This Y-chromosomal haplogroup accounts for 11% of Korean paternal lineages, and the frequency of the lineage is even more reduced in Japan. Yet this molecular marker may still be a tracer for the introduction of Altaic language to the archipelago, where the paternal lineage has persisted, albeit in a frequency of just 6%." According to Juha Janhunen, the ancestral languages of Turkic, Mongolic, Tungusic, Korean, and Japanese were spoken in a relatively small area comprising present-day North Korea, Southern Manchuria, and Southeastern Mongolia. However Janhunen is sceptical about an affiliation of Japanese to Altaic, while András Róna-Tas remarked that a relationship between Altaic and Japanese, if it ever existed, must be more remote than the relationship of any two of the Indo-European languages. Ramsey stated that "the genetic relationship between Korean and Japanese, if it in fact exists, is probably more complex and distant than we can imagine on the basis of our present state of knowledge". Supporters of the Altaic hypothesis formerly set the date of the Proto-Altaic language at around 4000 BC, but today at around 5000 BC or 6000 BC. This would make Altaic a language family older than Indo-European (around 3000 to 4000 BC according to mainstream hypotheses) but considerably younger than Afroasiatic (c. 10,000 BC or 11,000 to 16,000 BC according to different sources).

Axiom of choice

In mathematics, the axiom of choice, or AC, is an axiom of set theory equivalent to the statement that a Cartesian product of a collection of non-empty sets is non-empty. Informally put, the axiom of choice says that given any collection of sets, each containing at least one element, it is possible to construct a new set by arbitrarily choosing one element from each set, even if the collection is infinite. Formally, it states that for every indexed family of nonempty sets, there exists an indexed set such that for every . The axiom of choice was formulated in 1904 by Ernst Zermelo in order to formalize his proof of the well-ordering theorem. In many cases, a set arising from choosing elements arbitrarily can be made without invoking the axiom of choice; this is, in particular, the case if the number of sets from which to choose the elements is finite, or if a canonical rule on how to choose the elements is available – some distinguishing property that happens to hold for exactly one element in each set. An illustrative example is sets picked from the natural numbers. From such sets, one may always select the smallest number, e.g. given the sets {{4, 5, 6}, {10, 12}, {1, 400, 617, 8000}}, the set containing each smallest element is {4, 10, 1}. In this case, "select the smallest number" is a choice function. Even if infinitely many sets were collected from the natural numbers, it will always be possible to choose the smallest element from each set to produce a set. That is, the choice function provides the set of chosen elements. However, no definite choice function is known for the collection of all non-empty subsets of the real numbers (if there are non-constructible reals). In that case, the axiom of choice must be invoked. Bertrand Russell coined an analogy: for any (even infinite) collection of pairs of shoes, one can pick out the left shoe from each pair to obtain an appropriate collection (i.e. set) of shoes; this makes it possible to define a choice function directly. For an infinite collection of pairs of socks (assumed to have no distinguishing features), there is no obvious way to make a function that forms a set out of selecting one sock from each pair, without invoking the axiom of choice. Although originally controversial, the axiom of choice is now used without reservation by most mathematicians, and it is included in the standard form of axiomatic set theory, Zermelo–Fraenkel set theory with the axiom of choice (ZFC). One motivation for this use is that a number of generally accepted mathematical results, such as Tychonoff's theorem, require the axiom of choice for their proofs. Contemporary set theorists also study axioms that are not compatible with the axiom of choice, such as the axiom of determinacy. The axiom of choice is avoided in some varieties of constructive mathematics, although there are varieties of constructive mathematics in which the axiom of choice is embraced. Statement A choice function (also called selector or selection) is a function f, defined on a collection X of nonempty sets, such that for every set A in X, f(A) is an element of A. With this concept, the axiom can be stated: Formally, this may be expressed as follows: Thus, the negation of the axiom of choice states that there exists a collection of nonempty sets that has no choice function. (, so where is negation.) Each choice function on a collection X of nonempty sets is an element of the Cartesian product of the sets in X. This is not the most general situation of a Cartesian product of a family of sets, where a given set can occur more than once as a factor; however, one can focus on elements of such a product that select the same element every time a given set appears as factor, and such elements correspond to an element of the Cartesian product of all distinct sets in the family. The axiom of choice asserts the existence of such elements; it is therefore equivalent to: Given any family of nonempty sets, their Cartesian product is a nonempty set. Nomenclature ZF, AC, and ZFC In this article and other discussions of the Axiom of Choice the following abbreviations are common: AC – the Axiom of Choice. ZF – Zermelo–Fraenkel set theory omitting the Axiom of Choice. ZFC – Zermelo–Fraenkel set theory, extended to include the Axiom of Choice. Variants There are many other equivalent statements of the axiom of choice. These are equivalent in the sense that, in the presence of other basic axioms of set theory, they imply the axiom of choice and are implied by it. One variation avoids the use of choice functions by, in effect, replacing each choice function with its range: Given any set X of pairwise disjoint non-empty sets, there exists at least one set C that contains exactly one element in common with each of the sets in X. This guarantees for any partition of a set X the existence of a subset C of X containing exactly one element from each part of the partition. Another equivalent axiom only considers collections X that are essentially powersets of other sets: For any set A, the power set of A (with the empty set removed) has a choice function. Authors who use this formulation often speak of the choice function on A, but this is a slightly different notion of choice function. Its domain is the power set of A (with the empty set removed), and so makes sense for any set A, whereas with the definition used elsewhere in this article, the domain of a choice function on a collection of sets is that collection, and so only makes sense for sets of sets. With this alternate notion of choice function, the axiom of choice can be compactly stated as Every set has a choice function. which is equivalent to For any set A there is a function f such that for any non-empty subset B of A, f(B) lies in B. The negation of the axiom can thus be expressed as: There is a set A such that for all functions f (on the set of non-empty subsets of A), there is a B such that f(B) does not lie in B. Restriction to finite sets The usual statement of the axiom of choice does not specify whether the collection of nonempty sets is finite or infinite, and thus implies that every finite collection of nonempty sets has a choice function. However, that particular case is a theorem of the Zermelo–Fraenkel set theory without the axiom of choice (ZF); it is easily proved by the principle of finite induction. In the even simpler case of a collection of one set, a choice function just corresponds to an element, so this instance of the axiom of choice says that every nonempty set has an element; this holds trivially. The axiom of choice can be seen as asserting the generalization of this property, already evident for finite collections, to arbitrary collections. Usage Until the late 19th century, the axiom of choice was often used implicitly, although it had not yet been formally stated. For example, after having established that the set X contains only non-empty sets, a mathematician might have said "let F(s) be one of the members of s for all s in X" to define a function F. In general, it is impossible to prove that F exists without the axiom of choice, but this seems to have gone unnoticed until Zermelo. Examples The nature of the individual nonempty sets in the collection may make it possible to avoid the axiom of choice even for certain infinite collections. For example, suppose that each member of the collection X is a nonempty subset of the natural numbers. Every such subset has a smallest element, so to specify our choice function we can simply say that it maps each set to the least element of that set. This gives us a definite choice of an element from each set, and makes it unnecessary to add the axiom of choice to our axioms of set theory. The difficulty appears when there is no natural choice of elements from each set. If we cannot make explicit choices, how do we know that our selection forms a legitimate set (as defined by the other ZF axioms of set theory)? For example, suppose that X is the set of all non-empty subsets of the real numbers. First we might try to proceed as if X were finite. If we try to choose an element from each set, then, because X is infinite, our choice procedure will never come to an end, and consequently, we shall never be able to produce a choice function for all of X. Next we might try specifying the least element from each set. But some subsets of the real numbers do not have least elements. For example, the open interval (0,1) does not have a least element: if x is in (0,1), then so is x/2, and x/2 is always strictly smaller than x. So this attempt also fails. Additionally, consider for instance the unit circle S, and the action on S by a group G consisting of all rational rotations. Namely, these are rotations by angles which are rational multiples of π. Here G is countable while S is uncountable. Hence S breaks up into uncountably many orbits under G. Using the axiom of choice, we could pick a single point from each orbit, obtaining an uncountable subset X of S with the property that all of its translates by G are disjoint from X. The set of those translates partitions the circle into a countable collection of disjoint sets, which are all pairwise congruent. Since X is not measurable for any rotation-invariant countably additive finite measure on S, finding an algorithm to form a set from selecting a point in each orbit requires that one add the axiom of choice to our axioms of set theory. See non-measurable set for more details. The reason that we are able to choose least elements from subsets of the natural numbers is the fact that the natural numbers are well-ordered: every nonempty subset of the natural numbers has a unique least element under the natural ordering. One might say, "Even though the usual ordering of the real numbers does not work, it may be possible to find a different ordering of the real numbers which is a well-ordering. Then our choice function can choose the least element of every set under our unusual ordering." The problem then becomes that of constructing a well-ordering, which turns out to require the axiom of choice for its existence; every set can be well-ordered if and only if the axiom of choice holds. Criticism and acceptance A proof requiring the axiom of choice may establish the existence of an object without explicitly defining the object in the language of set theory. For example, while the axiom of choice implies that there is a well-ordering of the real numbers, there are models of set theory with the axiom of choice in which no well-ordering of the reals is definable. Similarly, although a subset of the real numbers that is not Lebesgue measurable can be proved to exist using the axiom of choice, it is consistent that no such set is definable. The axiom of choice proves the existence of these intangibles (objects that are proved to exist, but which cannot be explicitly constructed), which may conflict with some philosophical principles. Because there is no canonical well-ordering of all sets, a construction that relies on a well-ordering may not produce a canonical result, even if a canonical result is desired (as is often the case in category theory). This has been used as an argument against the use of the axiom of choice. Another argument against the axiom of choice is that it implies the existence of objects that may seem counterintuitive. One example is the Banach–Tarski paradox which says that it is possible to decompose the 3-dimensional solid unit ball into finitely many pieces and, using only rotations and translations, reassemble the pieces into two solid balls each with the same volume as the original. The pieces in this decomposition, constructed using the axiom of choice, are non-measurable sets. Despite these seemingly paradoxical facts, most mathematicians accept the axiom of choice as a valid principle for proving new results in mathematics. The debate is interesting enough, however, that it is considered of note when a theorem in ZFC (ZF plus AC) is logically equivalent (with just the ZF axioms) to the axiom of choice, and mathematicians look for results that require the axiom of choice to be false, though this type of deduction is less common than the type which requires the axiom of choice to be true. It is possible to prove many theorems using neither the axiom of choice nor its negation; such statements will be true in any model of ZF, regardless of the truth or falsity of the axiom of choice in that particular model. The restriction to ZF renders any claim that relies on either the axiom of choice or its negation unprovable. For example, the Banach–Tarski paradox is neither provable nor disprovable from ZF alone: it is impossible to construct the required decomposition of the unit ball in ZF, but also impossible to prove there is no such decomposition. Similarly, all the statements listed below which require choice or some weaker version thereof for their proof are unprovable in ZF, but since each is provable in ZF plus the axiom of choice, there are models of ZF in which each statement is true. Statements such as the Banach–Tarski paradox can be rephrased as conditional statements, for example, "If AC holds, then the decomposition in the Banach–Tarski paradox exists." Such conditional statements are provable in ZF when the original statements are provable from ZF and the axiom of choice. In constructive mathematics As discussed above, in ZFC, the axiom of choice is able to provide "nonconstructive proofs" in which the existence of an object is proved although no explicit example is constructed. ZFC, however, is still formalized in classical logic. The axiom of choice has also been thoroughly studied in the context of constructive mathematics, where non-classical logic is employed. The status of the axiom of choice varies between different varieties of constructive mathematics. In Martin-Löf type theory and higher-order Heyting arithmetic, the appropriate statement of the axiom of choice is (depending on approach) included as an axiom or provable as a theorem. Errett Bishop argued that the axiom of choice was constructively acceptable, saying In constructive set theory, however, Diaconescu's theorem shows that the axiom of choice implies the law of excluded middle (unlike in Martin-Löf type theory, where it does not). Thus the axiom of choice is not generally available in constructive set theory. A cause for this difference is that the axiom of choice in type theory does not have the extensionality properties that the axiom of choice in constructive set theory does. Some results in constructive set theory use the axiom of countable choice or the axiom of dependent choice, which do not imply the law of the excluded middle in constructive set theory. Although the axiom of countable choice in particular is commonly used in constructive mathematics, its use has also been questioned. Independence In 1938, Kurt Gödel showed that the negation of the axiom of choice is not a theorem of ZF by constructing an inner model (the constructible universe) which satisfies ZFC and thus showing that ZFC is consistent if ZF itself is consistent. In 1963, Paul Cohen employed the technique of forcing, developed for this purpose, to show that, assuming ZF is consistent, the axiom of choice itself is not a theorem of ZF. He did this by constructing a much more complex model which satisfies ZF¬C (ZF with the negation of AC added as axiom) and thus showing that ZF¬C is consistent. Together these results establish that the axiom of choice is logically independent of ZF. The assumption that ZF is consistent is harmless because adding another axiom to an already inconsistent system cannot make the situation worse. Because of independence, the decision whether to use the axiom of choice (or its negation) in a proof cannot be made by appeal to other axioms of set theory. The decision must be made on other grounds. One argument given in favor of using the axiom of choice is that it is convenient to use it because it allows one to prove some simplifying propositions that otherwise could not be proved. Many theorems which are provable using choice are of an elegant general character: the cardinalities of any two sets are comparable, every nontrivial ring with unity has a maximal ideal, every vector space has a basis, every connected graph has a spanning tree, and every product of compact spaces is compact, among many others. Without the axiom of choice, these theorems may not hold for mathematical objects of large cardinality. The proof of the independence result also shows that a wide class of mathematical statements, including all statements that can be phrased in the language of Peano arithmetic, are provable in ZF if and only if they are provable in ZFC. Statements in this class include the statement that P = NP, the Riemann hypothesis, and many other unsolved mathematical problems. When one attempts to solve problems in this class, it makes no difference whether ZF or ZFC is employed if the only question is the existence of a proof. It is possible, however, that there is a shorter proof of a theorem from ZFC than from ZF. The axiom of choice is not the only significant statement which is independent of ZF. For example, the generalized continuum hypothesis (GCH) is not only independent of ZF, but also independent of ZFC. However, ZF plus GCH implies AC, making GCH a strictly stronger claim than AC, even though they are both independent of ZF. Stronger axioms The axiom of constructibility and the generalized continuum hypothesis each imply the axiom of choice and so are strictly stronger than it. In class theories such as Von Neumann–Bernays–Gödel set theory and Morse–Kelley set theory, there is an axiom called the axiom of global choice that is stronger than the axiom of choice for sets because it also applies to proper classes. The axiom of global choice follows from the axiom of limitation of size. Tarski's axiom, which is used in Tarski–Grothendieck set theory and states (in the vernacular) that every set belongs to Grothendieck universe, is stronger than the axiom of choice. Equivalents There are important statements that, assuming the axioms of ZF but neither AC nor ¬AC, are equivalent to the axiom of choice. The most important among them are Zorn's lemma and the well-ordering theorem. In fact, Zermelo initially introduced the axiom of choice in order to formalize his proof of the well-ordering theorem. Set theory Tarski's theorem about choice: For every infinite set A, there is a bijective map between the sets A and A×A. Trichotomy: If two sets are given, then either they have the same cardinality, or one has a smaller cardinality than the other. Given two non-empty sets, one has a surjection to the other. Every surjective function has a right inverse. The Cartesian product of any family of nonempty sets is nonempty. In other words, every family of nonempty sets has a choice function (i.e. a function which maps each of the nonempty sets to one of its elements). König's theorem: Colloquially, the sum of a sequence of cardinals is strictly less than the product of a sequence of larger cardinals. (The reason for the term "colloquially" is that the sum or product of a "sequence" of cardinals cannot itself be defined without some aspect of the axiom of choice.) Well-ordering theorem: Every set can be well-ordered. Consequently, every cardinal has an initial ordinal. Every element of a partially ordered set S is the minimal element of a well-ordered subset having no strict upper bound in S. Zorn's lemma: Every non-empty partially ordered set in which every chain (i.e., totally ordered subset) has an upper bound contains at least one maximal element. Hausdorff maximal principle: Every partially ordered set has a maximal chain. Equivalently, in any partially ordered set, every chain can be extended to a maximal chain. Tukey's lemma: Every non-empty collection of finite character has a maximal element with respect to inclusion. Antichain principle: Every partially ordered set has a maximal antichain. Equivalently, in any partially ordered set, every antichain can be extended to a maximal antichain. Abstract algebra Every vector space has a basis (i.e., a linearly independent spanning subset). In other words, vector spaces are equivalent to free modules. Krull's theorem: Every unital ring (other than the trivial ring) contains a maximal ideal. Equivalently, in any nontrivial unital ring, every ideal can be extended to a maximal ideal. For every non-empty set S there is a binary operation defined on S that gives it a group structure. (A cancellative binary operation is enough, see group structure and the axiom of choice.) Every free abelian group is projective. Baer's criterion: Every divisible abelian group is injective. Every set is a projective object in the category Set of sets. Functional analysis The closed unit ball of the dual of a normed vector space over the reals has an extreme point. Point-set topology The Cartesian product of any family of connected topological spaces is connected. Tychonoff's theorem: The Cartesian product of any family of compact topological spaces is compact. In the product topology, the closure of a product of subsets is equal to the product of the closures. Mathematical logic If S is a set of sentences of first-order logic and B is a consistent subset of S, then B is included in a set that is maximal among consistent subsets of S. The special case where S is the set of all first-order sentences in a given signature is weaker, equivalent to the Boolean prime ideal theorem; see the section "Weaker forms" below. Algebraic topology Every connected graph has a spanning tree. Equivalently, every nonempty graph has a spanning forest. Category theory There are several results in category theory which invoke the axiom of choice for their proof. These results might be weaker than, equivalent to, or stronger than the axiom of choice, depending on the strength of the technical foundations. For example, if one defines categories in terms of sets, that is, as sets of objects and morphisms (usually called a small category), or even locally small categories, whose hom-objects are sets, then there is no category of all sets, and so it is difficult for a category-theoretic formulation to apply to all sets. On the other hand, other foundational descriptions of category theory are considerably stronger, and an identical category-theoretic statement of choice may be stronger than the standard formulation, à la class theory, mentioned above. Examples of category-theoretic statements which require choice include: Every small category has a skeleton. If two small categories are weakly equivalent, then they are equivalent. Every continuous functor on a small-complete category which satisfies the appropriate solution set condition has a left-adjoint (the Freyd adjoint functor theorem). Weaker forms There are several weaker statements that are not equivalent to the axiom of choice, but are closely related. One example is the axiom of dependent choice (DC). A still weaker example is the axiom of countable choice (ACω or CC), which states that a choice function exists for any countable set of nonempty sets. These axioms are sufficient for many proofs in elementary mathematical analysis, and are consistent with some principles, such as the Lebesgue measurability of all sets of reals, that are disprovable from the full axiom of choice. Given an ordinal parameter α ≥ ω+2 — for every set S with rank less than α, S is well-orderable. Given an ordinal parameter α ≥ 1 — for every set S with Hartogs number less than ωα, S is well-orderable. As the ordinal parameter is increased, these approximate the full axiom of choice more and more closely. Other choice axioms weaker than axiom of choice include the Boolean prime ideal theorem and the axiom of uniformization. The former is equivalent in ZF to Tarski's 1930 ultrafilter lemma: every filter is a subset of some ultrafilter. Results requiring AC (or weaker forms) but weaker than it One of the most interesting aspects of the axiom of choice is the large number of places in mathematics that it shows up. Here are some statements that require the axiom of choice in the sense that they are not provable from ZF but are provable from ZFC (ZF plus AC). Equivalently, these statements are true in all models of ZFC but false in some models of ZF. Set theory The ultrafilter lemma (with ZF) can be used to prove the Axiom of choice for finite sets: Given and a collection of non-empty sets, their product is not empty. The union of any countable family of countable sets is countable (this requires countable choice but not the full axiom of choice). If the set A is infinite, then there exists an injection from the natural numbers N to A (see Dedekind infinite). Eight definitions of a finite set are equivalent. Every infinite game in which is a Borel subset of Baire space is determined. Measure theory The Vitali theorem on the existence of non-measurable sets which states that there is a subset of the real numbers that is not Lebesgue measurable. The Hausdorff paradox. The Banach–Tarski paradox. Algebra Every field has an algebraic closure. Every field extension has a transcendence basis. Every infinite-dimensional vector field contains an infinite linearly independent subset (this requires dependent choice, but not the full axiom of choice). Stone's representation theorem for Boolean algebras needs the Boolean prime ideal theorem. The Nielsen–Schreier theorem, that every subgroup of a free group is free. The additive groups of R and C are isomorphic. Functional analysis The Hahn–Banach theorem in functional analysis, allowing the extension of linear functionals The theorem that every Hilbert space has an orthonormal basis. The Banach–Alaoglu theorem about compactness of sets of functionals. The Baire category theorem about complete metric spaces, and its consequences, such as the open mapping theorem and the closed graph theorem. On every infinite-dimensional topological vector space there is a discontinuous linear map. General topology A uniform space is compact if and only if it is complete and totally bounded. Every Tychonoff space has a Stone–Čech compactification. Mathematical logic Gödel's completeness theorem for first-order logic: every consistent set of first-order sentences has a completion. That is, every consistent set of first-order sentences can be extended to a maximal consistent set. The compactness theorem: If is a set of first-order (or alternatively, zero-order) sentences such that every finite subset of has a model, then has a model. Possibly equivalent implications of AC There are several historically important set-theoretic statements implied by AC whose equivalence to AC is open. The partition principle, which was formulated before AC itself, was cited by Zermelo as a justification for believing AC. In 1906, Russell declared PP to be equivalent, but whether the partition principle implies AC is still the oldest open problem in set theory, and the equivalences of the other statements are similarly hard old open problems. In every known model of ZF where choice fails, these statements fail too, but it is unknown if they can hold without choice. Set theory Partition principle: if there is a surjection from A to B, there is an injection from B to A. Equivalently, every partition P of a set S is less than or equal to S in size. Converse Schröder–Bernstein theorem: if two sets have surjections to each other, they are equinumerous. Weak partition principle: if there is a injection and a surjection from A to B, then A and B are equinumerous. Equivalently, a partition of a set S cannot be strictly larger than S. If WPP holds, this already implies the existence of a non-measurable set. Each of the previous three statements is implied by the preceding one, but it is unknown if any of these implications can be reversed. There is no infinite decreasing sequence of cardinals. The equivalence was conjectured by Schoenflies in 1905. Abstract algebra Hahn embedding theorem: Every ordered abelian group G order-embeds as a subgroup of the additive group endowed with a lexicographical order, where Ω is the set of Archimedean equivalence classes of G. This equivalence was conjectured by Hahn in 1907. Stronger forms of the negation of AC If we abbreviate by BP the claim that every set of real numbers has the property of Baire, then BP is stronger than ¬AC, which asserts the nonexistence of any choice function on perhaps only a single set of nonempty sets. Strengthened negations may be compatible with weakened forms of AC. For example, ZF + DC + BP is consistent, if ZF is. It is also consistent with ZF + DC that every set of reals is Lebesgue measurable; however, this consistency result, due to Robert M. Solovay, cannot be proved in ZFC itself, but requires a mild large cardinal assumption (the existence of an inaccessible cardinal). The much stronger axiom of determinacy, or AD, implies that every set of reals is Lebesgue measurable, has the property of Baire, and has the perfect set property (all three of these results are refuted by AC itself). ZF + DC + AD is consistent provided that a sufficiently strong large cardinal axiom is consistent (the existence of infinitely many Woodin cardinals). Quine's system of axiomatic set theory, New Foundations (NF), takes its name from the title ("New Foundations for Mathematical Logic") of the 1937 article which introduced it. In the NF axiomatic system, the axiom of choice can be disproved. Statements consistent with the negation of AC There are models of Zermelo-Fraenkel set theory in which the axiom of choice is false. We shall abbreviate "Zermelo-Fraenkel set theory plus the negation of the axiom of choice" by ZF¬C. For certain models of ZF¬C, it is possible to prove the negation of some standard facts. Any model of ZF¬C is also a model of ZF, so for each of the following statements, there exists a model of ZF in which that statement is true. There is a set that can be partitioned into strictly more equivalence classes than the original set has elements, and a function whose domain is strictly smaller than its range. In fact, this is the case in all known models. There is a function f from the real numbers to the real numbers such that f is not continuous at a, but f is sequentially continuous at a, i.e., for any sequence {xn} converging to a, limn f(xn)=f(a). There is an infinite set of real numbers without a countably infinite subset. The real numbers are a countable union of countable sets. This does not imply that the real numbers are countable: As pointed out above, to show that a countable union of countable sets is itself countable requires the Axiom of countable choice. There is a field with no algebraic closure. In all models of ZF¬C there is a vector space with no basis. There is a vector space with two bases of different cardinalities. There is a free complete boolean algebra on countably many generators. There is a set that cannot be linearly ordered. There exists a model of ZF¬C in which every set in Rn is measurable. Thus it is possible to exclude counterintuitive results like the Banach–Tarski paradox which are provable in ZFC. Furthermore, this is possible whilst assuming the Axiom of dependent choice, which is weaker than AC but sufficient to develop most of real analysis. In all models of ZF¬C, the generalized continuum hypothesis does not hold. For proofs, see . Additionally, by imposing definability conditions on sets (in the sense of descriptive set theory) one can often prove restricted versions of the axiom of choice from axioms incompatible with general choice. This appears, for example, in the Moschovakis coding lemma. Axiom of choice in type theory In type theory, a different kind of statement is known as the axiom of choice. This form begins with two types, σ and τ, and a relation R between objects of type σ and objects of type τ. The axiom of choice states that if for each x of type σ there exists a y of type τ such that R(x,y), then there is a function f from objects of type σ to objects of type τ such that R(x,f(x)) holds for all x of type σ: Unlike in set theory, the axiom of choice in type theory is typically stated as an axiom scheme, in which R varies over all formulas or over all formulas of a particular logical form. Quotations This is a joke: although the three are all mathematically equivalent, many mathematicians find the axiom of choice to be intuitive, the well-ordering principle to be counterintuitive, and Zorn's lemma to be too complex for any intuition. The observation here is that one can define a function to select from an infinite number of pairs of shoes, for example by choosing the left shoe from each pair. Without the axiom of choice, one cannot assert that such a function exists for pairs of socks, because left and right socks are (presumably) indistinguishable. Polish-American mathematician Jan Mycielski relates this anecdote in a 2006 article in the Notices of the AMS. This quote comes from the famous April Fools' Day article in the computer recreations column of the Scientific American, April 1989.

Aegean Sea

The Aegean Sea is an elongated embayment of the Mediterranean Sea between Europe and Asia. It is located between the Balkans and Anatolia, and covers an area of some 215,000 square kilometres. In the north, the Aegean is connected to the Marmara Sea and the Black Sea by the straits of the Dardanelles and the Bosphorus. The Aegean Islands are located within the sea and some bound it on its southern periphery, including Crete and Rhodes. The sea reaches a maximum depth of 2,639m to the west of Karpathos. The Thracian Sea and the Sea of Crete are main subdivisions of the Aegean Sea. The Aegean Islands can be divided into several island groups, including the Dodecanese, the Cyclades, the Sporades, the Saronic islands and the North Aegean Islands, as well as Crete and its surrounding islands. The Dodecanese, located to the southeast, includes the islands of Rhodes, Kos, and Patmos; the islands of Delos and Naxos are within the Cyclades to the south of the sea. Lesbos is part of the North Aegean Islands. Euboea, the second-largest island in Greece, is located in the Aegean, despite being administered as part of Central Greece. Nine out of twelve of the Administrative regions of Greece border the sea, along with the Turkish provinces of Edirne, Canakkale, Balıkesir, Izmir, Aydın and Muğla to the east of the sea. Various Turkish islands in the sea are Imbros, Tenedos, Cunda Island, and the Foça Islands. The Aegean Sea has been historically important, especially in regards to the civilization of Ancient Greece, who inhabited the area around the coast of the Aegean and the Aegean islands. The Aegean islands facilitated contact between the people of the area and between Europe and Asia. Along with the Greeks, Thracians lived among the northern coast. The Romans conquered the area under the Roman Empire, and later the Byzantine Empire held it against advances by the First Bulgarian Empire. The Fourth Crusade weakened Byzantine control of the area, and it was eventually conquered by the Ottoman Empire, with the exception of Crete, which was a Venetian colony until 1669. The Greek War of Independence allowed a Greek state on the coast of the Aegean from 1829 onwards. The Ottoman Empire held a presence over the sea for over 500 years, until it was replaced by modern Turkey. The rocks making up the floor of the Aegean are mainly limestone, though often greatly altered by volcanic activity that has convulsed the region in relatively recent geologic times. Of particular interest are the richly coloured sediments in the region of the islands of Santorini and Milos, in the south Aegean. Notable cities on the Aegean coastline include Athens, Thessaloniki, Volos, Kavala and Heraklion in Greece, and İzmir and Bodrum in Turkey. The Aegean Sea groundwater itself has a high salinity content leading one to think that the soil would be infertile due to the volcanic region, but actually has an equilibrium with its soil content structure making it able to grow fertile crops on land that would seem infertile. A number of issues concerning sovereignty within the Aegean Sea are disputed between Greece and Turkey. The Aegean dispute has had a large effect on Greek-Turkish relations since the 1970s. Issues include the delimitation of territorial waters, national airspace, exclusive economic zones and flight information regions. Name and etymology Late Latin authors referred the name Aegaeus to Aegeus, who was said to have jumped into that sea to drown himself (rather than throwing himself from the Athenian acropolis, as told by some Greek authors). He was the father of Theseus, the mythical king and founder-hero of Athens. Aegeus had told Theseus to put up white sails when returning if he was successful in killing the Minotaur. When Theseus returned, he forgot these instructions, and Aegeus thinking his son to have died then drowned himself in the sea. The sea was known in Latin as Mare Aegaeum under the control of the Roman Empire. The Venetians, who ruled many Greek islands in the High and Late Middle Ages, popularized the name Archipelago (, meaning "main sea" or "chief sea"), a name that held on in many European countries until the early modern period. In the South Slavic languages, the Aegean is called White Sea (; ; ). The Turkish name for the sea is Ege Denizi, derived from the Greek name. Geography The Aegean Sea is an elongated embayment of the Mediterranean Sea and covers about in area, measuring about longitudinally and latitudinal. The sea's maximum depth is , located at a point west of Karpathos. The Aegean Islands are found within its waters, with the following islands delimiting the sea on the south, generally from west to east: Kythera, Antikythera, Crete, Kasos, Karpathos and Rhodes. The Anatolian peninsula marks the eastern boundary of the sea, while the Greek mainland marks the west. Several seas are contained within the Aegean Sea; the Thracian Sea is a section of the Aegean located to the north, the Icarian Sea to the east, the Myrtoan Sea to the west, while the Sea of Crete is the southern section. The Greek regions that border the sea, in alphabetical order, are Attica, Central Greece, Central Macedonia, Crete, Eastern Macedonia and Thrace, North Aegean, Peloponnese, South Aegean, and Thessaly. The historical region of Macedonia also borders the sea, to the north. The Aegean Islands, which almost all belong to Greece, can be divided into seven groups: Northeastern Aegean Islands, which lie in the Thracian Sea East Aegean Islands (Euboea) Northern Sporades Cyclades Saronic Islands (or Argo-Saronic Islands) Dodecanese (or Southern Sporades) Crete Many of the Aegean islands or island chains, are geographically extensions of the mountains on the mainland. One chain extends across the sea to Chios, another extends across Euboea to Samos, and a third extends across the Peloponnese and Crete to Rhodes, dividing the Aegean from the Mediterranean. The bays and gulfs of the Aegean beginning at the South and moving clockwise include on Crete, the Mirabello, Almyros, Souda and Chania bays or gulfs, on the mainland the Myrtoan Sea to the west with the Argolic Gulf, the Saronic Gulf northwestward, the Petalies Gulf which connects with the South Euboic Sea, the Pagasetic Gulf which connects with the North Euboic Sea, the Thermian Gulf northwestward, the Chalkidiki Peninsula including the Cassandra and the Singitic Gulfs, northward the Strymonian Gulf and the Gulf of Kavala and the rest are in Turkey; Saros Gulf, Edremit Gulf, Dikili Gulf, Gulf of Çandarlı, Gulf of İzmir, Gulf of Kuşadası, Gulf of Gökova, Güllük Gulf. The Aegean sea is connected to the Sea of Marmara by the Dardanelles, also known from Classical Antiquity as the Hellespont. The Dardanelles are located to the northeast of the sea. It ultimately connects with the Black Sea through the Bosphoros strait, upon which lies the city of Istanbul. The Dardanelles and the Bosphoros are known as the Turkish Straits. Extent According to the International Hydrographic Organization, the limits of the Aegean Sea as follows: On the south: A line running from Cape Aspro (28°16′E) in Asia Minor, to Cum Burnù (Capo della Sabbia) the Northeast extreme of the Island of Rhodes, through the island to Cape Prasonisi, the Southwest point thereof, on to Vrontos Point (35°33′N) in Skarpanto [Karpathos], through this island to Castello Point, the South extreme thereof, across to Cape Plaka (East extremity of Crete), through Crete to Agria Grabusa, the Northwest extreme thereof, thence to Cape Apolitares in Antikithera Island, through the island to Psira Rock (off the Northwest point) and across to Cape Trakhili in Kithera Island, through Kithera to the Northwest point (Cape Karavugia) and thence to Cape Santa Maria () in the Morea. In the Dardanelles: A line joining Kum Kale (26°11′E) and Cape Helles. Hydrography Aegean surface water circulates in a counterclockwise gyre, with hypersaline Mediterranean water moving northward along the west coast of Turkey, before being displaced by less dense Black Sea outflow. The dense Mediterranean water sinks below the Black Sea inflow to a depth of , then flows through the Dardanelles Strait and into the Sea of Marmara at velocities of . The Black Sea outflow moves westward along the northern Aegean Sea, then flows southwards along the east coast of Greece. The physical oceanography of the Aegean Sea is controlled mainly by the regional climate, the fresh water discharge from major rivers draining southeastern Europe, and the seasonal variations in the Black Sea surface water outflow through the Dardanelles Strait. Analysis of the Aegean during 1991 and 1992 revealed three distinct water masses: Aegean Sea Surface Water – thick veneer, with summer temperatures of 21–26 °C and winter temperatures ranging from in the north to in the south. Aegean Sea Intermediate Water – Aegean Sea Intermediate Water extends from 40 to 50 m to with temperatures ranging from 11 to 18 °C. Aegean Sea Bottom Water – occurring at depths below 500–1000 m with a very uniform temperature (13–14 °C) and salinity (3.91–3.92%). Climate The climate of the Aegean Sea largely reflects the climate of Greece and Western Turkey, which is to say, predominately Mediterranean. According to the Köppen climate classification, most of the Aegean is classified as Hot-summer Mediterranean (Csa), with hotter and drier summers along with milder and wetter winters. However, high temperatures during summers are generally not quite as high as those in arid or semiarid climates due to the presence of a large body of water. This is most predominant in the west and east coasts of the Aegean, and within the Aegean islands. In the north of the Aegean Sea, the climate is instead classified as Cold semi-arid (BSk), which feature cooler summers than Hot-summer Mediterranean climates. The Etesian winds are a dominant weather influence in the Aegean Basin. The below table lists climate conditions of some major Aegean cities: Population Numerous Greek and Turkish settlements are located along their mainland coast, as well as on towns on the Aegean islands. The largest cities are Athens and Thessaloniki in Greece and İzmir in Turkey. The most populated of the Aegean islands is Crete, followed by Euboea and Rhodes. Biogeography and ecology Protected Areas Greece has established several marine protected areas along its coasts. According to the Network of Managers of Marine Protected Areas in the Mediterranean (MedPAN), four Greek MPAs are participating in the Network. These include Alonnisos Marine Park, while the Missolonghi–Aitoliko Lagoons and the island of Zakynthos are not on the Aegean. History Ancient history The current coastline dates back to about 4000 BC. Before that time, at the peak of the last ice age (about 18,000 years ago) sea levels everywhere were 130 metres lower, and there were large well-watered coastal plains instead of much of the northern Aegean. When they were first occupied, the present-day islands including Milos with its important obsidian production were probably still connected to the mainland. The present coastal arrangement appeared around 9,000 years ago, with post-ice age sea levels continuing to rise for another 3,000 years after that. The subsequent Bronze Age civilizations of Greece and the Aegean Sea have given rise to the general term Aegean civilization. In ancient times, the sea was the birthplace of two ancient civilizations – the Minoans of Crete and the Myceneans of the Peloponnese. The Minoan civilization was a Bronze Age civilization on the island of Crete and other Aegean islands, flourishing from around 3000 to 1450 BC before a period of decline, finally ending at around 1100 BC. It represented the first advanced civilization in Europe, leaving behind massive building complexes, tools, stunning artwork, writing systems, and a massive network of trade. The Minoan period saw extensive trade between Crete, Aegean, and Mediterranean settlements, particularly the Near East. The most notable Minoan palace is that of Knossos, followed by that of Phaistos. The Mycenaean Greeks arose on the mainland, becoming the first advanced civilization in mainland Greece, which lasted from approximately 1600 to 1100 BC. It is believed that the site of Mycenae, which sits close to the Aegean coast, was the center of Mycenaean civilization. The Mycenaeans introduced several innovations in the fields of engineering, architecture and military infrastructure, while trade over vast areas of the Mediterranean, including the Aegean, was essential for the Mycenaean economy. Their syllabic script, the Linear B, offers the first written records of the Greek language and their religion already included several deities that can also be found in the Olympic Pantheon. Mycenaean Greece was dominated by a warrior elite society and consisted of a network of palace-centered states that developed rigid hierarchical, political, social and economic systems. At the head of this society was the king, known as wanax. The civilization of Mycenaean Greeks perished with the collapse of Bronze Age culture in the eastern Mediterranean, to be followed by the so-called Greek Dark Ages. It is undetermined what cause the collapse of the Mycenaeans. During the Greek Dark Ages, writing in the Linear B script ceased, vital trade links were lost, and towns and villages were abandoned. Ancient Greece The Archaic period followed the Greek Dark Ages in the 8th century BC. Greece became divided into small self-governing communities, and adopted the Phoenician alphabet, modifying it to create the Greek alphabet. By the 6th century BC several cities had emerged as dominant in Greek affairs: Athens, Sparta, Corinth, and Thebes, of which Athens, Sparta, and Corinth were closest to the Aegean Sea. Each of them had brought the surrounding rural areas and smaller towns under their control, and Athens and Corinth had become major maritime and mercantile powers as well. In the 8th and 7th centuries BC many Greeks emigrated to form colonies in Magna Graecia (Southern Italy and Sicily), Asia Minor and further afield. The Aegean Sea was the setting for one of the most pivotal naval engagements in history, when on September 20, 480 B.C. the Athenian fleet gained a decisive victory over the Persian fleet of the Xerxes II of Persia at the Battle of Salamis. Thus ending any further attempt of western expansion by the Achaemenid Empire. The Aegean Sea would later come to be under the control, albeit briefly, of the Kingdom of Macedonia. Philip II and his son Alexander the Great led a series of conquests that led not only to the unification of the Greek mainland and the control of the Aegean Sea under his rule, but also the destruction of the Achaemenid Empire. After Alexander the Great's death, his empire was divided among his generals. Cassander became king of the Hellenistic kingdom of Macedon, which held territory along the western coast of the Aegean, roughly corresponding to modern-day Greece. The Kingdom of Lysimachus had control over the sea's eastern coast. Greece had entered the Hellenistic period. Roman rule The Macedonian Wars were a series of conflicts fought by the Roman Republic and its Greek allies in the eastern Mediterranean against several different major Greek kingdoms. They resulted in Roman control or influence over the eastern Mediterranean basin, including the Aegean, in addition to their hegemony in the western Mediterranean after the Punic Wars. During Roman rule, the land around the Aegean Sea fell under the provinces of Achaea, Macedonia, Thracia, Asia and Creta et Cyrenica (island of Crete) Medieval period The Fall of the Western Roman Empire allowed its successor state, the Byzantine Empire, to continue Roman control over the Aegean Sea. However, their territory would later be threatened by the Early Muslim conquests initiated by Muhammad in the 7th century. Although the Rashidun Caliphate did not manage to obtain land along the coast of the Aegean sea, its conquest of the Eastern Anatolian peninsula as well as Egypt, the Levant, and North Africa left the Byzantine Empire weakened. The Umayyad Caliphate expanded the territorial gains of the Rashidun Caliphate, conquering much of North Africa, and threatened the Byzantine Empire's control of Western Anatolia, where it meets the Aegean Sea. During the 820s, Crete was conquered by a group of Berbers Andalusians exiles led by Abu Hafs Umar al-Iqritishi, and it became an independent Islamic state. The Byzantine Empire launched a campaign that took most of the island back in 842 and 843 under Theoktistos, but the reconquest was not completed and was soon reversed. Later attempts by the Byzantine Empire to recover the island were without success. For the approximately 135 years of its existence, the emirate of Crete was one of the major foes of Byzantium. Crete commanded the sea lanes of the Eastern Mediterranean and functioned as a forward base and haven for Muslim corsair fleets that ravaged the Byzantine-controlled shores of the Aegean Sea. Crete returned to Byzantine rule under Nikephoros Phokas, who launched a huge campaign against the Emirate of Crete in 960 to 961. Meanwhile, the Bulgarian Empire threatened Byzantine control of Northern Greece and the Aegean coast to the south. Under Presian I and his successor Boris I, the Bulgarian Empire managed to obtain a small portion of the northern Aegean coast. Simeon I of Bulgaria led Bulgaria to its greatest territorial expansion, and managed to conqueror much of the northern and western coasts of the Aegean. The Byzantines later regained control. The Second Bulgarian Empire achieved similar success along, again, the northern and western coasts, under Ivan Asen II of Bulgaria. The Seljuq Turks, under the Seljuk Empire, invaded the Byzantine Empire in 1068, from which they annexed almost all the territories of Anatolia, including the east coast of the Aegean Sea, during the reign of Alp Arslan, the second Sultan of the Seljuk Empire. After the death of his successor, Malik Shah I, the empire was divided, and Malik Shah was succeeded in Anatolia by Kilij Arslan I, who founded the Sultanate of Rum. The Byzantines yet again recaptured the eastern coast of the Aegean. After Constantinople was occupied by Western European and Venetian forces during the Fourth Crusade, the area around the Aegean sea was fragmented into multiple entities, including the Latin Empire, the Kingdom of Thessalonica, the Empire of Nicaea, the Principality of Achaea, and the Duchy of Athens. The Venetians created the maritime state of the Duchy of the Archipelago, which included all the Cyclades except Mykonos and Tinos. The Empire of Nicaea, a Byzantine rump state, managed to effect the Recapture of Constantinople from the Latins in 1261 and defeat Epirus. Byzantine successes were not to last; the Ottomans would conquer the area around the Aegean coast, but before their expansion the Byzantine Empire had already been weakened from internal conflict. By the late 14th century the Byzantine Empire had lost all control of the coast of the Aegean Sea and could exercise power around their capital, Constantinople. The Ottoman Empire then gained control of all the Aegean coast with the exception of Crete, which was a Venetian colony until 1669. Modern Period The Greek War of Independence allowed a Greek state on the coast of the Aegean from 1829 onward. The Ottoman Empire held a presence over the sea for over 500 years until its dissolution following World War I, when it was replaced by modern Turkey. During the war, Greece gained control over the area around the northern coast of the Aegean. By the 1930s, Greece and Turkey had about resumed their present-day borders. In the Italo-Turkish War of 1912, Italy captured the Dodecanese islands, and had occupied them since, reneging on the 1919 Venizelos–Tittoni agreement to cede them to Greece. The Greco-Italian War took place from October 1940 to April 1941 as part of the Balkans Campaign of World War II. The Italian war aim was to establish a Greek puppet state, which would permit the Italian annexation of the Sporades and the Cyclades islands in the Aegean Sea, to be administered as a part of the Italian Aegean Islands. The German invasion resulted in the Axis occupation of Greece. The German troops evacuated Athens on 12 October 1944, and by the end of the month, they had withdrawn from mainland Greece. Greece was then liberated by Allied troops. Economy and politics Many of the islands in the Aegean have safe harbours and bays. In ancient times, navigation through the sea was easier than travelling across the rough terrain of the Greek mainland, and to some extent, the coastal areas of Anatolia. Many of the islands are volcanic, and marble and iron are mined on other islands. The larger islands have some fertile valleys and plains. The Armenian king dynasty Achaemenids made one of the greatest highways of the Ancient world. Its name was "Royal road," its length was 2400km, and it was situated between Persian Empire and the Aegean sea. A part of the road passed by the southwest of Armenia, which gave an excellent opportunity to participate in international trading. Of the main islands in the Aegean Sea, two belong to Turkey – Bozcaada (Tenedos) and Gökçeada (Imbros); the rest belong to Greece. Between the two countries, there are political disputes over several aspects of political control over the Aegean space, including the size of territorial waters, air control and the delimitation of economic rights to the continental shelf. These issues are known as the Aegean dispute. Transport Multiple ports are located along the Greek and Turkish coasts of the Aegean Sea. The port of Piraeus in Athens is the chief port in Greece, the largest passenger port in Europe and the third largest in the world, servicing about 20 million passengers annually. With a throughput of 1.4 million TEUs, Piraeus is placed among the top ten ports in container traffic in Europe and the top container port in the Eastern Mediterranean. Piraeus is also the commercial hub of Greek shipping. Piraeus bi-annually acts as the focus for a major shipping convention, known as Posidonia, which attracts maritime industry professionals from all over the world. Piraeus is currently Greece's third-busiest port in terms of tons of goods transported, behind Aghioi Theodoroi and Thessaloniki. The central port serves ferry routes to almost every island in the eastern portion of Greece, the island of Crete, the Cyclades, the Dodecanese, and much of the northern and the eastern Aegean Sea, while the western part of the port is used for cargo services. As of 2007, the Port of Thessaloniki was the second-largest container port in Greece after the port of Piraeus, making it one of the busiest ports in Greece. In 2007, the Port of Thessaloniki handled 14,373,245 tonnes of cargo and 222,824 TEU's. Paloukia, on the island of Salamis, is a major passenger port. Fishing Fish are Greece's second-largest agricultural export, and Greece has Europe's largest fishing fleet. Fish captured include sardines, mackerel, grouper, grey mullets, sea bass, and seabream. There is a considerable difference between fish catches between the pelagic and demersal zones; with respect to pelagic fisheries, the catches from the northern, central and southern Aegean area groupings are dominated, respectively, by anchovy, horse mackerels, and boops. For demersal fisheries, the catches from the northern and southern Aegean area groupings are dominated by grey mullets and pickerel (Spicara smaris) respectively. The industry has been impacted by the Great Recession. Overfishing and habitat destruction is also a concern, threatening grouper, and seabream populations, resulting in perhaps a 50% decline of fish catch. To address these concerns, Greek fishermen have been offered a compensation by the government. Although some species are defined as protected or threatened under EU legislation, several illegal species such as the molluscs Pinna nobilis, Charonia tritonis and Lithophaga lithophaga, can be bought in restaurants and fish markets around Greece. Tourism The Aegean islands within the Aegean Sea are significant tourist destinations. Tourism to the Aegean islands contributes a significant portion of tourism in Greece, especially since the second half of the 20th century. A total of five UNESCO World Heritage sites are located the Aegean Islands; these include the Monastery of Saint John the Theologian and the Cave of the Apocalypse on Patmos, the Pythagoreion and Heraion of Samos in Samos, the Nea Moni of Chios, the island of Delos, and the Medieval City of Rhodes. Greece is one of the most visited countries in Europe and the world with over 33 million visitors in 2018, and the tourism industry around a quarter of Greece's Gross Domestic Product. The islands of Santorini, Crete, Lesbos, Delos, and Mykonos are common tourist destinations. An estimated 2 million tourists visit Santorini annually. However, concerns relating to overtourism have arisen in recent years, such as issues of inadequate infrastructure and overcrowding. Alongside Greece, Turkey has also been successful in developing resort areas and attracting large number of tourists, contributing to tourism in Turkey. The phrase "Blue Cruise" refers to recreational voyages along the Turkish Riviera, including across the Aegean. The ancient city of Troy, a World Heritage Site, is on the Turkish coast of the Aegean. Greece and Turkey both take part in the Blue Flag beach certification programme of the Foundation for Environmental Education. The certification is awarded for beaches and marinas meeting strict quality standards including environmental protection, water quality, safety and services criteria. As of 2015, the Blue Flag has been awarded to 395 beaches and 9 marinas in Greece. Southern Aegean beaches on the Turkish coast include Muğla, with 102 beaches awarded with the blue flag, along with İzmir and Aydın, who have 49 and 30 beaches awarded respectively.

A Clockwork Orange (novel)

A Clockwork Orange is a dystopian satirical black comedy novel by English writer Anthony Burgess, published in 1962. It is set in a near-future society that has a youth subculture of extreme violence. The teenage antagonist, Alex, narrates his violent exploits and his experiences with state authorities intent on reforming him. The book is partially written in a Russian-influenced argot called "Nadsat", which takes its name from the Russian suffix that is equivalent to '-teen' in English. According to Burgess, it was a jeu d'esprit written in just three weeks. In 2005, A Clockwork Orange was included on Time magazine's list of the 100 best English-language novels written since 1923, and it was named by Modern Library and its readers as one of the 100 best English-language novels of the 20th century. The original manuscript of the book has been kept at McMaster University's William Ready Division of Archives and Research Collections in Hamilton, Ontario, Canada since the institution purchased the documents in 1971. It is considered one of the most influential dystopian books. In 2022, the novel was included on the "Big Jubilee Read" list of 70 books by Commonwealth authors selected to celebrate the Platinum Jubilee of Elizabeth II. Plot summary Part 1: Alex's world Alex is a 15-year-old gang leader living in a near-future dystopian city. His friends ("droogs" in the novel's Anglo-Russian slang, "Nadsat") and fellow gang members are Dim, a slow-witted bruiser, who is the gang's muscle; Georgie, an ambitious second-in-command; and Pete, who mostly plays along as the droogs indulge their taste for "ultra-violence" (random, violent mayhem). Characterised as a psychopath and hardened juvenile delinquent, Alex is also intelligent, quick-witted, and enjoys classical music; he is particularly fond of Beethoven, whom he calls "Lovely Ludwig Van". The droogs sit in their favourite hangout, the Korova Milk Bar, drinking "milk-plus" (milk laced with the customer's drug of choice) to prepare for a night of ultra-violence. They assault a scholar walking home from the public library; rob a store, leaving the owner and his wife bloodied and unconscious; beat up a beggar; then scuffle with a rival gang. Joyriding through the countryside in a stolen car, they break into an isolated cottage and terrorise the young couple living there, beating the husband and gang-raping his wife. In a metafictional touch, the husband is a writer working on a manuscript called "A Clockwork Orange", and Alex contemptuously reads out a paragraph that states the novel's main theme before shredding the manuscript. At the Korova, Alex strikes Dim for his crude response to a woman's singing of an operatic passage, and strains within the gang become apparent. At home in his parents' flat, Alex plays classical music at top volume, which he describes as giving him orgasmic bliss before falling asleep. Alex feigns illness to his parents to stay out of school the next day. Following an unexpected visit from P.R. Deltoid, his "post-corrective adviser", Alex visits a record store, where he meets two pre-teen girls. He invites them back to the flat, where he drugs and rapes them. That night after a nap, Alex finds his droogs in a mutinous mood, waiting downstairs in the torn-up and graffitied lobby. Georgie challenges Alex for leadership of the gang, demanding that they focus on higher-value targets in their robberies. Alex quells the rebellion by slashing Dim's hand and fighting with Georgie, then soothes the gang by agreeing to Georgie's plan to rob the home of a wealthy elderly woman. Alex breaks in and knocks the woman unconscious, but when he hears sirens and opens the door to flee, Dim strikes him in payback for the earlier fight. The gang abandons Alex on the front step to be arrested by the police; while in custody, he learns that the woman has died from her injuries. Part 2: The Ludovico Technique Alex is convicted of murder and sentenced to 14 years in prison. His parents visit one day to inform him that Georgie has been killed in a botched robbery. Two years into his term, he has obtained a job in one of the prison chapels, playing music on the stereo to accompany the Sunday Christian services. The chaplain mistakes Alex's Bible studies for stirrings of faith; in reality, Alex only reads Scripture for the violent or sexual passages. After his fellow cellmates blame him for beating a troublesome cellmate to death, he is chosen to undergo an experimental behaviour modification treatment called the Ludovico Technique in exchange for having the remainder of his sentence commuted. The technique is a form of aversion therapy in which Alex is injected with nausea-inducing drugs while watching graphically violent films, eventually conditioning him to become severely ill at the mere thought of violence. As an unintended consequence, the soundtrack to one of the films, Beethoven's Ninth Symphony, renders Alex unable to enjoy his beloved classical music as before. The technique's effectiveness is demonstrated to a group of VIPs, who watch as Alex collapses before a man who slaps him and abases himself before a scantily clad young woman. Although the prison chaplain accuses the state of stripping Alex of free will, the government officials on the scene are pleased with the results, and Alex is released from prison. Part 3: After prison Alex returns to his parents' flat, only to find that they are letting his room to a lodger. Now homeless, he wanders the streets and enters a public library, hoping to learn of a painless method for committing suicide. The old scholar whom Alex had assaulted in Part 1 finds him and beats him with the help of several friends. Two policemen come to Alex's rescue, but they turn out to be Dim and Billyboy, a former rival gang leader. They take Alex outside town, brutalise him, and abandon him there. Alex collapses at the door of an isolated cottage, realising too late that it is the one he and his droogs invaded in Part 1. The writer, F. Alexander, still lives here, but his wife has since died of what he believes to be injuries she sustained in the rape. He does not recognise Alex but gives him shelter and questions him about the conditioning he has undergone. Alexander and his colleagues, all highly critical of the government, plan to use Alex as a symbol of state brutality and thus prevent the incumbent government from being re-elected. Alex inadvertently reveals that he was the ringleader of the home invasion; he is removed from the cottage and locked in an upper-story bedroom as a relentless barrage of classical music plays over speakers. He attempts suicide by leaping from the window. Alex wakes up in a hospital, where he is courted by government officials, anxious to counter the bad publicity created by his suicide attempt. He is informed that F. Alexander has been "put away" for Alex's protection and his own. Alex is offered a well-paying job if he agrees to side with the government once discharged. A round of tests reveals that his old violent impulses have returned, indicating that the hospital doctors have undone the effects of his conditioning. As photographers snap pictures, Alex daydreams of orgiastic violence and reflects, "I was cured all right." In the final chapter, Alex—now 18 years old and working for the nation's musical recording archives—finds himself halfheartedly preparing for another night of crime with a new gang (Len, Rick, and Bully). After a chance encounter with Pete, who has reformed and married, Alex finds himself taking less and less pleasure in acts of senseless violence. He begins contemplating giving up crime himself to become a productive member of society and start a family of his own while reflecting on the notion that his children could end up being just as destructive as he has been, if not more so. Omission of the final chapter in the US The book has three parts, each with seven chapters. Burgess has stated that the total of 21 chapters was an intentional nod to the age of 21 being recognised as a milestone in human maturation. The 21st chapter was omitted from the editions published in the United States prior to 1986. In the introduction to the updated American text (these newer editions include the missing 21st chapter), Burgess explains that when he first brought the book to an American publisher, he was told that US audiences would never go for the final chapter, in which Alex sees the error of his ways, decides he has lost his taste for violence and resolves to turn his life around. At the American publisher's insistence, Burgess allowed their editors to cut the redeeming final chapter from the US version, so that the tale would end on a darker note, with Alex becoming his old, ultraviolent self again – an ending which the publisher insisted would be "more realistic" and appealing to a US audience. The film adaptation, directed by Stanley Kubrick, is based on the American edition of the book, and is considered to be "badly flawed" by Burgess. Kubrick called Chapter 21 "an extra chapter" and claimed that he had not read the original version until he had virtually finished the screenplay and that he had never given serious consideration to using it. In Kubrick's opinion – as in the opinion of other readers, including the original American editor – the final chapter was unconvincing and inconsistent with the book. Kubrick's stance was unusual when compared to the standard Hollywood practice of producing films with the familiar tropes of resolving moral messages and good triumphing over evil before the film's end. Characters Alex: The novel's main antagonist and leader among his droogs. He often refers to himself as "Your Humble Narrator". Having coaxed two ten-year-old girls into his bedroom, Alex refers to himself as "Alexander the Large" while raping them; this was later the basis for Alex's claimed surname DeLarge in the 1971 film. George, Georgie or Georgie Boy: Effectively Alex's greedy second-in-command. Georgie attempts to undermine Alex's status as leader of the gang and take over their gang as the new leader. He is later killed during a botched robbery while Alex is in prison. Pete: The only one who does not take particular sides when the droogs fight among themselves. He later meets and marries a girl named Georgina, renouncing his violent ways and even losing his former (Nadsat) speech patterns. A chance encounter with Pete in the final chapter influences Alex to realise that he has grown bored with violence and recognise that human energy is better expended on creation than destruction. Dim: An idiotic and thoroughly gormless member of the gang, persistently condescended to by Alex, but respected to some extent by his droogs for his formidable fighting abilities, his weapon of choice being a length of bike chain. He later becomes a police officer, exacting his revenge on Alex for the abuse he once suffered under his command. P. R. Deltoid: A criminal rehabilitation social worker assigned the task of keeping Alex on the straight and narrow. He seemingly has no clue about dealing with young people, and is devoid of empathy or understanding for his troublesome charge. Indeed, when Alex is arrested for murdering an old woman and then ferociously beaten by several police officers, Deltoid simply spits on him. Prison Chaplain: The character who first questions whether it is moral to turn a violent person into a behavioural automaton who can make no choice in such matters. This is the only character who is truly concerned about Alex's welfare; he is not taken seriously by Alex, though. He is nicknamed by Alex "prison charlie" or "chaplin", a pun on Charlie Chaplin. Billyboy: A rival of Alex's. Early on in the story, Alex and his droogs battle Billyboy and his droogs, which ends abruptly when the police arrive. Later, after Alex is released from prison, Billyboy (along with Dim, who like Billyboy has become a police officer) rescues Alex from a mob, then subsequently beats him in a location out of town. Prison Governor: The man who decides to let Alex "choose" to be the first reformed by the Ludovico technique. The Minister of the Interior: The government high-official who determined that the Ludovico's technique will be used to cut recidivism. He is referred to as the Inferior by Alex. Dr Branom: A scientist, co-developer of the Ludovico technique. He appears friendly and almost paternal towards Alex at first, before forcing him into the theatre and what Alex calls the "chair of torture". Dr Brodsky: Branom's colleague and co-developer of the Ludovico technique. He seems much more passive than Branom and says considerably less. F. Alexander: An author who was in the process of typing his magnum opus A Clockwork Orange when Alex and his droogs broke into his house, beat him, tore up his work and then brutally gang-raped his wife, which caused her subsequent death. He is left deeply scarred by these events and when he encounters Alex two years later, he uses him as a guinea pig in a sadistic experiment intended to prove the Ludovico technique unsound. The government imprisons him afterwards. He is given the name Frank Alexander in the film. Cat Woman: An indirectly named woman who blocks Alex's gang's entrance scheme, and threatens to shoot Alex and set her cats on him if he does not leave. After Alex breaks into her house, she fights with him, ordering her cats to join the melee, but reprimands Alex for fighting them off. She sustains a fatal blow to the head during the scuffle. She is given the name Miss Weathers in the film. Analysis Background A Clockwork Orange was written in Hove, then a senescent English seaside town. Burgess had arrived back in Britain after his stint abroad to see that much had changed. A youth culture had developed, based around coffee bars, pop music and teenage gangs. England was gripped by fears over juvenile delinquency. Burgess stated that the novel's inspiration was his first wife Lynne's beating by a gang of drunk American servicemen stationed in England during World War II. She subsequently miscarried. In its investigation of free will, the book's target is ostensibly the concept of behaviourism, pioneered by such figures as B. F. Skinner. Burgess later stated that he wrote the book in three weeks. Title Burgess has offered several clarifications about the meaning and origin of its title: He had overheard the phrase "as queer as a clockwork orange" in a London pub in 1945 and assumed it was a Cockney expression. In Clockwork Marmalade, an essay published in the Listener in 1972, he said that he had heard the phrase several times since that occasion. He also explained the title in response to a question from William Everson on the television programme Camera Three in 1972, "Well, the title has a very different meaning but only to a particular generation of London Cockneys. It's a phrase which I heard many years ago and so fell in love with, I wanted to use it, the title of the book. But the phrase itself I did not make up. The phrase "as queer as a clockwork orange" is good old East London slang and it didn't seem to me necessary to explain it. Now, obviously, I have to give it an extra meaning. I've implied an extra dimension. I've implied the junction of the organic, the lively, the sweet – in other words, life, the orange – and the mechanical, the cold, the disciplined. I've brought them together in this kind of oxymoron, this sour-sweet word." Nonetheless, no other record of the expression being used before 1962 has ever appeared. Kingsley Amis notes in his Memoirs (1991) that no trace of it appears in Eric Partridge's Dictionary of Historical Slang. The saying "as queer as ..." followed by an improbable object: "... a clockwork orange", or "... a four-speed walking stick" or "... a left-handed corkscrew" etc. predates Burgess's novel. An early example, "as queer as Dick's hatband", appeared in 1796, and was alluded to in 1757. His second explanation was that it was a pun on the Malay word orang, meaning "man". The novella contains no other Malay words or links. In a prefatory note to A Clockwork Orange: A Play with Music, he wrote that the title was a metaphor for "an organic entity, full of juice and sweetness and agreeable odour, being turned into a mechanism". In his essay Clockwork Oranges, Burgess asserts that "this title would be appropriate for a story about the application of Pavlovian or mechanical laws to an organism which, like a fruit, was capable of colour and sweetness". While addressing the reader in a letter before some editions of the book, the author says that when a man ceases to have free will, they are no longer a man. "Just a clockwork orange", a shiny, appealing object, but "just a toy to be wound-up by either God or the Devil, or (what is increasingly replacing both) the State." This title alludes to the protagonist's negative emotional responses to feelings of evil which prevent the exercise of his free will subsequent to the administration of the Ludovico Technique. To induce this conditioning, Alex is forced to watch scenes of violence on a screen that are systematically paired with negative physical stimulation. The negative physical stimulation takes the form of nausea and "feelings of terror", which are caused by an emetic medicine administered just before the presentation of the films. Use of slang The book, narrated by Alex, contains many words in a slang argot which Burgess invented for the book, called Nadsat. It is a mix of modified Slavic words, Cockney rhyming slang and derived Russian (like baboochka). For instance, these terms have the following meanings in Nadsat: droog (друг) = friend; moloko (молоко) = milk; gulliver (голова) = head; malchick (мальчик) or malchickiwick = boy; soomka (сумка) = sack or bag; Bog (Бог) = God; horrorshow (хорошо) = good; prestoopnick (преступник) = criminal; rooker (рука) = hand; cal (кал) = crap; veck (человек) = man or guy; litso (лицо) = face; malenky (маленький) = little; and so on. Some words Burgess invented himself or just adapted from pre-existing languages. Compare Polari. One of Alex's doctors explains the language to a colleague as "odd bits of old rhyming slang; a bit of gypsy talk, too. But most of the roots are Slav propaganda. Subliminal penetration." Some words are not derived from anything, but merely easy to guess, e.g. "in-out, in-out" or "the old in-out" means sexual intercourse. Cutter, however, means "money", because "cutter" rhymes with "bread-and-butter"; this is rhyming slang, which is intended to be impenetrable to outsiders (especially eavesdropping policemen). Additionally, slang like appypolly loggy ("apology") seems to derive from school boy slang. This reflects Alex's age of 15. In the first edition of the book, no key was provided, and the reader was left to interpret the meaning from the context. In his appendix to the restored edition, Burgess explained that the slang would keep the book from seeming dated, and served to muffle "the raw response of pornography" from the acts of violence. The term "ultraviolence", referring to excessive or unjustified violence, was coined by Burgess in the book, which includes the phrase "do the ultra-violent". The term's association with aesthetic violence has led to its use in the media. Banning and censorship history in the US In 1976, A Clockwork Orange was removed from an Aurora, Colorado high school because of "objectionable language". A year later in 1977 it was removed from high school classrooms in Westport, Massachusetts over similar concerns with "objectionable" language. In 1982, it was removed from two Anniston, Alabama libraries, later to be reinstated on a restricted basis. Also, in 1973 a bookseller was arrested for selling the novel. The charges were later dropped. However, each of these instances came after the release of Stanley Kubrick's popular 1971 film adaptation of A Clockwork Orange, itself the subject of much controversy. Reception Initial response The Sunday Telegraph review was positive, and described the book as "entertaining ... even profound". Kingsley Amis in The Observer acclaimed the novel as "cheerful horror", writing "Mr Burgess has written a fine farrago of outrageousness, one which incidentally suggests a view of juvenile violence I can't remember having met before". Malcolm Bradbury wrote "All of Mr Burgess's powers as a comic writer, which are considerable, have gone into the rich language of his inverted Utopia. If you can stomach the horrors, you'll enjoy the manner". Roald Dahl called it "a terrifying and marvellous book". Many reviewers praised the inventiveness of the language, but expressed unease at the violent subject matter. The Spectator praised Burgess's "extraordinary technical feat" but was uncomfortable with "a certain arbitrariness about the plot which is slightly irritating". New Statesman acclaimed Burgess for addressing "acutely and savagely the tendencies of our time" but called the book "a great strain to read". The Sunday Times review was negative, and described the book as "a very ordinary, brutal and psychologically shallow story". The Times also reviewed the book negatively, describing it as "a somewhat clumsy experiment with science fiction [with] clumsy cliches about juvenile delinquency". The violence was criticised as "unconvincing in detail". Writer's appraisal Burgess dismissed A Clockwork Orange as "too didactic to be artistic". He said that the violent content of the novel "nauseated" him. In 1985, Burgess published Flame into Being: The Life and Work of D. H. Lawrence and while discussing Lady Chatterley's Lover in his biography, Burgess compared the notoriety of D. H. Lawrence's novel with A Clockwork Orange: "We all suffer from the popular desire to make the known notorious. The book I am best known for, or only known for, is a novel I am prepared to repudiate: written a quarter of a century ago, a jeu d'esprit knocked off for money in three weeks, it became known as the raw material for a film which seemed to glorify sex and violence. The film made it easy for readers of the book to misunderstand what it was about, and the misunderstanding will pursue me until I die. I should not have written the book because of this danger of misinterpretation, and the same may be said of Lawrence and Lady Chatterley's Lover." Awards and nominations and rankings 1983 – Prometheus Award (Preliminary Nominee) 1999 – Prometheus Award (Nomination) 2002 – Prometheus Award (Nomination) 2003 – Prometheus Award (Nomination) 2006 – Prometheus Award (Nomination) 2008 – Prometheus Award (Hall of Fame Award) A Clockwork Orange was chosen by Time magazine as one of the 100 best English-language books from 1923 to 2005. Adaptations A 1965 film by Andy Warhol entitled Vinyl was an adaptation of Burgess's novel. The best known adaptation of the novella is the 1971 film A Clockwork Orange by Stanley Kubrick, featuring Malcolm McDowell as Alex. In 1987, Burgess published a stage play titled A Clockwork Orange: A Play with Music. The play includes songs, written by Burgess, which are inspired by Beethoven and Nadsat slang. A manga anthology by Osamu Tezuka entitled Tokeijikake no Ringo (Clockwork Apple) was released in 1983. In 1988, a German adaptation of A Clockwork Orange at the intimate theatre of Bad Godesberg featured a musical score by the German punk rock band Die Toten Hosen which, combined with orchestral clips of Beethoven's Ninth Symphony and "other dirty melodies" (so stated by the subtitle), was released on the album Ein kleines bisschen Horrorschau. The track Hier kommt Alex became one of the band's signature songs. In February 1990, another musical version was produced at the Barbican Theatre in London by the Royal Shakespeare Company. Titled A Clockwork Orange: 2004, it received mostly negative reviews, with John Peter of The Sunday Times of London calling it "only an intellectual Rocky Horror Show", and John Gross of The Sunday Telegraph calling it "a clockwork lemon". Even Burgess himself, who wrote the script based on his novel, was disappointed. According to The Evening Standard, he called the score, written by Bono and The Edge of the rock group U2, "neo-wallpaper". Burgess had originally worked alongside the director of the production, Ron Daniels, and envisioned a musical score that was entirely classical. Unhappy with the decision to abandon that score, he heavily criticised the band's experimental mix of hip hop, liturgical and gothic music. Lise Hand of The Irish Independent reported The Edge as saying that Burgess's original conception was "a score written by a novelist rather than a songwriter". Calling it "meaningless glitz", Jane Edwardes of 20/20 magazine said that watching this production was "like being invited to an expensive French Restaurant – and being served with a Big Mac." In 1994, Chicago's Steppenwolf Theater put on a production of A Clockwork Orange directed by Terry Kinney. The American premiere of novelist Anthony Burgess's own adaptation of his A Clockwork Orange starred K. Todd Freeman as Alex. In 2001, UNI Theatre (Mississauga, Ontario) presented the Canadian premiere of the play under the direction of Terry Costa. In 2002, Godlight Theatre Company presented the New York Premiere adaptation of A Clockwork Orange at Manhattan Theatre Source. The production went on to play at the SoHo Playhouse (2002), Ensemble Studio Theatre (2004), 59E59 Theaters (2005) and the Edinburgh Festival Fringe (2005). While at Edinburgh, the production received rave reviews from the press while playing to sold-out audiences. The production was directed by Godlight's artistic director, Joe Tantalo. In 2003, Los Angeles director Brad Mays and the ARK Theatre Company staged a multi-media adaptation of A Clockwork Orange, which was named "Pick of the Week" by the LA Weekly and nominated for three of the 2004 LA Weekly Theater Awards: Direction, Revival Production (of a 20th-century work), and Leading Female Performance. Vanessa Claire Smith won Best Actress for her gender-bending portrayal of Alex, the music-loving teenage sociopath. This production utilised three separate video streams outputted to seven onstage video monitors – six 19-inch and one 40-inch. In order to preserve the first-person narrative of the book, a pre-recorded video stream of Alex, "your humble narrator", was projected onto the 40-inch monitor, thereby freeing the onstage character during passages which would have been awkward or impossible to sustain in the breaking of the fourth wall. An adaptation of the work, based on the original novel, the film and Burgess's own stage version, was performed by the SiLo Theatre in Auckland, New Zealand in early 2007. In 2021, the International Anthony Burgess Foundation premiered a webpage cataloging various productions of A Clockwork Orange from around the world.

Amsterdam

Amsterdam ( , , ; lit. "The Dam on the River Amstel") is the capital and most populous city of the Netherlands, with The Hague being the seat of government. It has a population of 921,402 within the city proper, 1,457,018 in the urban area and 2,480,394 in the metropolitan area. Located in the Dutch province of North Holland, Amsterdam is colloquially referred to as the "Venice of the North", for its large number of canals, now designated a UNESCO World Heritage Site. Amsterdam was founded at the mouth of the Amstel River that was dammed to control flooding; the city's name derives from the Amstel dam. Originally a small fishing village in the late 12th century, Amsterdam became a major world port during the Dutch Golden Age of the 17th century, when the Netherlands was an economic powerhouse. Amsterdam is the leading center for finance and trade, as well as a hub of production of secular art. In the 19th and 20th centuries, the city expanded and many new neighborhoods and suburbs were planned and built. The canals of Amsterdam and the 19-20th century Defence Line of Amsterdam are both on the UNESCO World Heritage List. Sloten, annexed in 1921 by the municipality of Amsterdam, is the oldest part of the city, dating to the 9th century. The city has a long tradition of openness, liberalism, and tolerance. Cycling is key to the city's modern character, and there are numerous biking paths and lanes spread throughout the entire city. Amsterdam's main attractions include its historic canals; the , the state museum with a vast collection of Dutch Golden Age art; the Van Gogh Museum; the Dam Square, where the Royal Palace of Amsterdam and former city hall () are located; the Amsterdam Museum; Stedelijk Museum, with modern art; Hermitage Amsterdam, the concert hall; the Anne Frank House; the , the Heineken Experience, the ; Hortus Botanicus, NEMO, the red-light district and many cannabis coffee shops. The city is also well known for its nightlife and festival activity; with several of its nightclubs (, Paradiso) among the world's most famous. Primarily known for its artistic heritage, elaborate canal system and narrow canal houses with gabled façades; well-preserved legacies of the city's 17th-century Golden Age, and the establishment of the Van Gogh Museum, displaying the work of the famous Dutch modern artist, have attracted millions of visitors to Amsterdam annually. The Amsterdam Stock Exchange is considered the oldest "modern" securities market stock exchange in the world. As the commercial capital of the Netherlands and one of the top financial centres in Europe, Amsterdam is considered an alpha world city by the Globalization and World Cities Research Network. The city is also the cultural capital of the Netherlands. Many large Dutch institutions have their headquarters in the city, including: the Philips conglomerate, AkzoNobel, Booking.com, TomTom, and ING. Many of the world's largest companies are based in Amsterdam or have established their European headquarters in the city, such as leading technology companies Uber, Netflix and Tesla. In 2022, Amsterdam was ranked the ninth-best city in the world to live in by the Economist Intelligence Unit and 12th globally on quality of living for environment and infrastructure by Mercer. The city was ranked 4th place globally as top tech hub in the Savills Tech Cities 2019 report (2nd in Europe), and 3rd in innovation by Australian innovation agency 2thinknow in their Innovation Cities Index 2009. The Port of Amsterdam is the fifth largest in Europe. The KLM hub and Amsterdam's main airport, Schiphol, is the busiest airport in the Netherlands, the third busiest in Europe, and the 11th busiest airport in the world. The Dutch capital is considered one of the most multicultural cities in the world, with at least 177 nationalities represented. Immigration and ethnic segregation in Amsterdam is a current issue. A few of Amsterdam's notable residents throughout its history include painters Rembrandt and Vincent van Gogh, seventeenth-century philosopher Baruch Spinoza, and the Holocaust victim and diarist Anne Frank. History Prehistory Due to its geographical location in what used to be wet peatland, the founding of Amsterdam is later than other urban centers in the Low Countries. However, around the area of what later became Amsterdam, farmers settled as early as three millennia ago. They lived along the prehistoric IJ river and upstream of its tributary Amstel. The prehistoric IJ was a shallow and quiet stream in peatland behind beach ridges. This secluded area was able to grow into an important local settlement center, especially in the late Bronze Age, the Iron Age and the Roman Age. Neolithic and Roman artefacts have also been found in the prehistoric Amstel bedding under Amsterdam's Damrak and Rokin, such as shards of Bell Beaker culture pottery (2200-2000 BC) and a granite grinding stone (2700-2750 BC), but the location of these artefacts around the river banks of the Amstel probably point to a presence of a modest semi-permanent or seasonal settlement. Until water issues were controlled, a permanent settlement would not have been possible, since the river mouth and the banks of the Amstel in this period in time were too wet for permanent habitation. Founding The origins of Amsterdam is linked to the development of the peatland called Amestelle, meaning 'watery area', from Aa(m) 'river' + stelle 'site at a shoreline', 'river bank'. In this area, land reclamation started as early as the late 10th century. Amestelle was located along a side arm of the IJ. This side arm took the name from the eponymous land: Amstel. Amestelle was inhabited by farmers, who lived more inland and more upstream, where the land was not as wet as at the banks of the downstream river mouth. These farmers were starting the reclamation around upstream Ouderkerk aan de Amstel, and later at the other side of the river at Amstelveen. The Van Amstel family, known in documents by this name since 1019, held the stewardship in this northwestern nook of the ecclesiastical district of the bishop of Utrecht. The family later served also under the count of Holland. A major turning point in the development of the Amstel river mouth was the All Saint's Flood of 1170. In an extremely short period of time, the shallow river IJ turned into a wide estuary, which from then on offered the Amstel an open connection to the Zuiderzee, IJssel and waterways further afield. This made the water flow of the Amstel more active, so excess water could be drained better. With drier banks, the downstream Amstel mouth became attractive for permanent habitation. Moreover, the river had grown from an insignificant peat stream into a junction of international waterways. A settlement was built here immediately after the landscape change of 1170. Right from the start of its foundation it focused on traffic, production and trade; not on farming, as opposed to how communities had lived further upstream for the past 200 years and northward for thousands of years. The construction of a dam at the mouth of the Amstel, eponymously named Dam, is historically estimated to have occurred between 1264 and 1275. The settlement first appeared in a document from 1275, concerning a road toll granted by the count of Holland Floris V to the residents apud Amestelledamme 'at the dam in the Amstel' or 'at the dam of Amstelland'. This allowed the inhabitants of the village to travel freely through the County of Holland, paying no tolls at bridges, locks and dams. This was a move in a years-long struggle for power in the area between the count of Holland and the Amstel family who governed the area on behalf of the bishop of Utrecht. By 1327, the name had developed into Aemsterdam. Middle Ages The bishop of Utrecht granted Amsterdam city rights in either 1300 or 1306. Het Mirakel van Amsterdam in 1345, rendered the city an important place of pilgrimage. During the heydays of the Stille Omgang, which became the expression of the pilgrimage after the Protestant Reformation, up to 90,000 pilgrims came to Amsterdam. From the 14th century on, Amsterdam flourished, largely from trade with the Hanseatic League. From the 15th century on the city established an independent trade route with the Baltic Sea in grain and timber, cutting out the Hanseatic League as middlemen. The city became the staple market of Europe for bulk cargo.This was made possible due to innovations in the herring fishery, from which Amsterdam reaped great wealth. Herring had demand in markets all around Europe. Inventions of on-board gibbing and the haringbuis in 1415, made longer voyages feasible, and hence enabled Dutch fishermen to follow the herring shoals far from the coasts, giving them a monopoly in the industry. The herring industry relied on international trade cooperation and large initial investments in ships, which needed many highly skilled and unskilled workers cooperating, which required the import of the necessary raw materials to turn an unfinished product into a marketable one, which required merchants to then sell it throughout the continent and book-keepers and accountants to devide the profit. In short, the herring industry was setting up the foundations for what would later become the transcontinental trade system and the Dutch Golden Age, with Amsterdam at its center, hence the saying "Amsterdam is built on Herring bones". Conflict with Spain The Low Countries were part of the Hapsburg inheritance and came under the Spanish monarchy in the early sixteenth century. The Dutch rebelled against Philip II of Spain, who led a defense of Catholicism during the Protestant Reformation. The main reasons for the uprising were the imposition of new taxes, the tenth penny, and the religious persecution of Protestants by the newly introduced Inquisition. The revolt escalated into the Eighty Years' War, which ultimately led to Dutch independence. Strongly pushed by Dutch Revolt leader William the Silent, the Dutch Republic became known for its relative religious tolerance. Jews from the Iberian Peninsula, Protestant Huguenots from France, prosperous merchants and printers from Flanders, and economic and religious refugees from the Spanish-controlled parts of the Low Countries found safety in Amsterdam. The influx of Flemish printers and the city's intellectual tolerance made Amsterdam a center for the European free press. Center of the Dutch Golden Age During the 17th century, Amsterdam experienced what is considered its Golden Age, during which it became the wealthiest city in the Western world. Ships sailed from Amsterdam to the Baltic Sea, the Caribbean, North America, and Africa, as well as present-day Indonesia, India, Sri Lanka, and Brazil, forming the basis of a worldwide trading network. Amsterdam's merchants had the largest share in both the Dutch East India Company (VOC) and the Dutch West India Company. These companies acquired overseas possessions that later became Dutch colonies. Amsterdam was Europe's most important hub for the shipment of goods and was the leading financial center of the western world. In 1602, the Amsterdam office of the Dutch East India Company became the world's first stock exchange by trading in its own shares. The Bank of Amsterdam started operations in 1609, acting as a full-service bank for Dutch merchant bankers and as a reserve bank. Beginning during this period, Amsterdam also became involved in the trade in African slaves. The city was a major destination port for Dutch slave ships beginning in the 17th century, which lasted until the United Netherlands abolished the Dutch involvement in the trade in 1814 under pressure by the British government. Amsterdam was also a member of the Society of Suriname, an organization founded to oversee the management of Surinam, a Dutch slave colony. On 1 July 2021, the mayor of Amsterdam, Femke Halsema, apologized for the city's involvement in the African slave trade, which had contributed to the city's wealth. Decline and modernization Amsterdam's prosperity declined during the 18th and early 19th centuries. The wars of the Dutch Republic with England (latterly, Great Britain) and France took their toll on the city. During the Napoleonic Wars, Amsterdam's significance reached its lowest point, with Holland being absorbed into the French Empire. However, the later establishment of the United Kingdom of the Netherlands in 1815 marked a turning point. The end of the 19th century is sometimes called Amsterdam's second Golden Age. New museums, a railway station, and the were built; in this same time, the Industrial Revolution reached the city. The Amsterdam–Rhine Canal was dug to give Amsterdam a direct connection to the Rhine, and the North Sea Canal was dug to give the port a shorter connection to the North Sea. Both projects dramatically improved commerce with the rest of Europe and the world. In 1906, Joseph Conrad gave a brief description of Amsterdam as seen from the seaside, in The Mirror of the Sea. 20th century–present Shortly before the First World War, the city started to expand again, and new suburbs were built. Even though the Netherlands remained neutral in this war, Amsterdam suffered a food shortage, and heating fuel became scarce. The shortages sparked riots in which several people were killed. These riots are known as the Aardappeloproer (Potato rebellion). People started looting stores and warehouses in order to get supplies, mainly food. On 1 January 1921, after a flood in 1916, the depleted municipalities of Durgerdam, Holysloot, Zunderdorp and Schellingwoude, all lying north of Amsterdam, were, at their own request, annexed to the city. Between the wars, the city continued to expand, most notably to the west of the Jordaan district in the Frederik Hendrikbuurt and surrounding neighbourhoods. Nazi Germany invaded the Netherlands on 10 May 1940 and took control of the country. Some Amsterdam citizens sheltered Jews, thereby exposing themselves and their families to a high risk of being imprisoned or sent to concentration camps. More than 100,000 Dutch Jews were deported to Nazi concentration camps, of whom some 60,000 lived in Amsterdam. In response, the Dutch Communist Party organized the February strike attended by 300,000 people to protest against the raids. The most famous deportee was the young Jewish girl Anne Frank, who died in the Bergen-Belsen concentration camp. At the end of the Second World War, communication with the rest of the country broke down, and food and fuel became scarce. Many citizens traveled to the countryside to forage. Dogs, cats, raw sugar beets, and tulip bulbs—cooked to a pulp—were consumed to stay alive. Many trees in Amsterdam were cut down for fuel, and wood was taken from the houses, apartments and other buildings of deported Jews. Many new suburbs, such as Osdorp, Slotervaart, Slotermeer and Geuzenveld, were built in the years after the Second World War. These suburbs contained many public parks and wide-open spaces, and the new buildings provided improved housing conditions with larger and brighter rooms, gardens, and balconies. Because of the war and other events of the 20th century, almost the entire city centre had fallen into disrepair. As society was changing, politicians and other influential figures made plans to redesign large parts of it. There was an increasing demand for office buildings, and also for new roads, as the automobile became available to most people. A metro started operating in 1977 between the new suburb of Bijlmermeer in the city's Zuidoost (southeast) exclave and the centre of Amsterdam. Further plans were to build a new highway above the metro to connect Amsterdam Centraal and the city centre with other parts of the city. The required large-scale demolitions began in Amsterdam's former Jewish neighborhood. Smaller streets, such as the Jodenbreestraat and Weesperstraat, were widened and almost all houses and buildings were demolished. At the peak of the demolition, the Nieuwmarktrellen (Nieuwmarkt Riots) broke out; the rioters expressed their fury about the demolition caused by the restructuring of the city. As a result, the demolition was stopped and the highway into the city's centre was never fully built; only the metro was completed. Only a few streets remained widened. The new city hall was built on the almost completely demolished Waterlooplein. Meanwhile, large private organizations, such as Stadsherstel Amsterdam, were founded to restore the entire city centre. Although the success of this struggle is visible today, efforts for further restoration are still ongoing. The entire city centre has reattained its former splendour and, as a whole, is now a protected area. Many of its buildings have become monuments, and in July 2010 the Grachtengordel (the three concentric canals: Herengracht, Keizersgracht, and Prinsengracht) was added to the UNESCO World Heritage List. In the 21st century, the Amsterdam city centre has attracted large numbers of tourists: between 2012 and 2015, the annual number of visitors rose from 10 to 17 million. Real estate prices have surged, and local shops are making way for tourist-oriented ones, making the centre unaffordable for the city's inhabitants. These developments have evoked comparisons with Venice, a city thought to be overwhelmed by the tourist influx. Construction of a new metro line connecting the part of the city north of the IJ to its southern part was started in 2003. The project was controversial because its cost had exceeded its budget by a factor of three by 2008, because of fears of damage to buildings in the centre, and because construction had to be halted and restarted multiple times. The new metro line was completed in 2018. Since 2014, renewed focus has been given to urban regeneration and renewal, especially in areas directly bordering the city centre, such as Frederik Hendrikbuurt. This urban renewal and expansion of the traditional centre of the city—with the construction on artificial islands of the new eastern IJburg neighbourhood—is part of the Structural Vision Amsterdam 2040 initiative. Geography Amsterdam is located in the Western Netherlands, in the province of North Holland, the capital of which is not Amsterdam, but rather Haarlem. The river Amstel ends in the city centre and connects to a large number of canals that eventually terminate in the IJ. Amsterdam is about below sea level. The surrounding land is flat as it is formed of large polders. An artificial forest, Amsterdamse Bos, is in the southwest. Amsterdam is connected to the North Sea through the long North Sea Canal. Amsterdam is intensely urbanised, as is the Amsterdam metropolitan area surrounding the city. Comprising of land, the city proper has 4,457 inhabitants per km2 and 2,275 houses per km2. Parks and nature reserves make up 12% of Amsterdam's land area. Water Amsterdam has more than of canals, most of which are navigable by boat. The city's three main canals are the Prinsengracht, Herengracht and Keizersgracht. In the Middle Ages, Amsterdam was surrounded by a moat, called the Singel, which now forms the innermost ring in the city, and gives the city centre a horseshoe shape. The city is also served by a seaport. It has been compared with Venice, due to its division into about 90 islands, which are linked by more than 1,200 bridges. Climate Amsterdam has an oceanic climate (Köppen: Cfb) strongly influenced by its proximity to the North Sea to the west, with prevailing westerly winds. Amsterdam, as well as most of the North Holland province, lies in USDA Hardiness zone 8b. Frosts mainly occur during spells of easterly or northeasterly winds from the inner European continent. Even then, because Amsterdam is surrounded on three sides by large bodies of water, as well as having a significant heat-island effect, nights rarely fall below , while it could easily be in Hilversum, southeast. Summers are moderately warm with a number of hot and humid days with occasional rain every month. The average daily high in August is , and or higher is only measured on average on 2.5 days, placing Amsterdam in AHS Heat Zone 2. The record extremes range from to . Days with more than of precipitation are common, on average 133 days per year. Amsterdam's average annual precipitation is . A large part of this precipitation falls as light rain or brief showers. Cloudy and damp days are common during the cooler months of October through March. Demographics Historical population In 1300, Amsterdam's population was around 1,000 people. While many towns in Holland experienced population decline during the 15th and 16th centuries, Amsterdam's population grew, mainly due to the rise of the profitable Baltic maritime trade especially in grain after the Burgundian victory in the Dutch–Hanseatic War in 1441. The population of Amsterdam was only modest compared to the towns and cities of Flanders and Brabant, which comprised the most urbanized area of the Low Countries. This changed when, during the Dutch Revolt, many people from the Southern Netherlands fled to the North, especially after Antwerp fell to Spanish forces in 1585. Jews from Spain, Portugal and Eastern Europe similarly settled in Amsterdam, as did Germans and Scandinavians. In thirty years, Amsterdam's population more than doubled between 1585 and 1610. By 1600, its population was around 50,000. During the 1660s, Amsterdam's population reached 200,000. The city's growth levelled off and the population stabilized around 240,000 for most of the 18th century. In 1750, Amsterdam was the fourth largest city in Western Europe, behind London (676,000), Paris (560,000) and Naples (324,000). This was all the more remarkable as Amsterdam was neither the capital city nor the seat of government of the Dutch Republic, which itself was a much smaller state than Great Britain, France or the Ottoman Empire. In contrast to those other metropolises, Amsterdam was also surrounded by large towns such as Leiden (about 67,000), Rotterdam (45,000), Haarlem (38,000) and Utrecht (30,000). The city's population declined in the early 19th century, dipping under 200,000 in 1820. By the second half of the 19th century, industrialization spurred renewed growth. Amsterdam's population hit an all-time high of 872,000 in 1959, before declining in the following decades due to government-sponsored suburbanisation to so-called groeikernen (growth centres) such as Purmerend and Almere. Between 1970 and 1980, Amsterdam experienced its sharp population decline, peaking at a net loss of 25,000 people in 1973. By 1985 the city had only 675,570 residents. This was soon followed by reurbanization and gentrification, leading to renewed population growth in the 2010s. Also in the 2010s, much of Amsterdam's population growth was due to immigration to the city. Immigration In the 16th and 17th century, non-Dutch immigrants to Amsterdam were mostly Protestant Huguenots and Flemings, Sephardic Jews, and Westphalians. Huguenots came after the Edict of Fontainebleau in 1685, while the Flemish Protestants came during the Eighty Years' War against Catholic Spain. The Westphalians came to Amsterdam mostly for economic reasons; their influx continued through the 18th and 19th centuries. Before the Second World War, 10% of the city population was Jewish. Just twenty percent of them survived the Holocaust. The first mass immigration in the 20th century was by people from Indonesia, who came to Amsterdam after the independence of the Dutch East Indies in the 1940s and 1950s. In the 1960s guest workers from Turkey, Morocco, Italy, and Spain emigrated to Amsterdam. After the independence of Suriname in 1975, a large wave of Surinamese settled in Amsterdam, mostly in the Bijlmer area. Other immigrants, including refugees asylum seekers and undocumented immigrants, came from Europe, the Americas, Asia and Africa. In the 1970s and 1980s, many 'old' Amsterdammers moved to 'new' cities like Almere and Purmerend, prompted by the third Land-use planning bill of the Dutch Government. This bill promoted suburbanization and arranged for new developments in so-called "groeikernen", literally cores of growth. Young professionals and artists moved into neighborhoods De Pijp and the Jordaan abandoned by these Amsterdammers. The non-Western immigrants settled mostly in the social housing projects in Amsterdam-West and the Bijlmer. Today, people of non-Western origin make up approximately one-fifth of the population of Amsterdam, and more than 30% of the city's children. Ethnic Dutch (as defined by the Dutch census) now make up a minority of the total population, although by far the largest one. Only one in three inhabitants under 15 is an autochthon, or a person who has two parents of Dutch origin. Segregation along ethnic lines is clearly visible, with people of non-Western origin, considered a separate group by Statistics Netherlands, concentrating in specific neighborhoods especially in Nieuw-West, Zeeburg, Bijlmer and in certain areas of Amsterdam-Noord. In 2000, Christians formed the largest religious group in the city (28% of the population). The next largest religion was Islam (8%), most of whose followers were Sunni. In 2015, Christians formed the largest religious group in the city (28% of the population). The next largest religion was Islam (7.1%), most of whose followers were Sunni. Religion In 1578, the largely Catholic city of Amsterdam joined the revolt against Spanish rule, late in comparison to other major northern Dutch cities. Catholic priests were driven out of the city. Following the Dutch takeover, all churches were converted to Protestant worship. Calvinism was declared the main religion; although Catholicism was not forbidden and priests allowed to serve, the Catholic hierarchy was prohibited. This led to the establishment of schuilkerken, covert religious buildings that were hidden in pre-existing buildings. Catholics, some Jewish and dissenting Protestants worshiped in such buildings. A large influx of foreigners of many religions came to 17th-century Amsterdam, in particular Sefardic Jews from Spain and Portugal, Huguenots from France, Lutherans, Mennonites, as well as Protestants from across the Netherlands. This led to the establishment of many non-Dutch-speaking churches. In 1603, the Jewish received permission to practice their religion in the city. In 1639, the first synagogue was consecrated. The Jews came to call the town 'Jerusalem of the West'. As they became established in the city, other Christian denominations used converted Catholic chapels to conduct their own services. The oldest English-language church congregation in the world outside the United Kingdom is found at the Begijnhof. Regular services there are still offered in English under the auspices of the Church of Scotland. Being Calvinists, the Huguenots soon integrated into the Dutch Reformed Church, though often retaining their own congregations. Some, commonly referred by the moniker 'Walloon', are recognizable today as they offer occasional services in French. In the second half of the 17th century, Amsterdam experienced an influx of Ashkenazim, Jews from Central and Eastern Europe. Jews often fled the pogroms in those areas. The first Ashkenazis who arrived in Amsterdam were refugees from the Khmelnytsky Uprising occurring in Ukraine and the Thirty Years' War, which devastated much of Central Europe. They not only founded their own synagogues, but had a strong influence on the 'Amsterdam dialect' adding a large Yiddish local vocabulary. Despite an absence of an official Jewish ghetto, most Jews preferred to live in the eastern part, which used to be the center of medieval Amsterdam. The main street of this Jewish neighbourhood was Jodenbreestraat. The neighbourhood comprised the Waterlooplein and the Nieuwmarkt. Buildings in this neighbourhood fell into disrepair after the Second World War a large section of the neighbourhood was demolished during the construction of the metro system. This led to riots, and as a result the original plans for large-scale reconstruction were abandoned by the government. The neighbourhood was rebuilt with smaller-scale residence buildings on the basis of its original layout. Catholic churches in Amsterdam have been constructed since the restoration of the episcopal hierarchy in 1853. One of the principal architects behind the city's Catholic churches, Cuypers, was also responsible for the Amsterdam Centraal station and the . In 1924, the Catholic Church hosted the International Eucharistic Congress in Amsterdam; numerous Catholic prelates visited the city, where festivities were held in churches and stadiums. Catholic processions on the public streets, however, were still forbidden under law at the time. Only in the 20th century was Amsterdam's relation to Catholicism normalised, but despite its far larger population size, the episcopal see of the city was placed in the provincial town of Haarlem. Historically, Amsterdam has been predominantly Christian, in 1900 Christians formed the largest religious group in the city (70% of the population), Dutch Reformed Church formed 45% of the city population, while the Catholic Church formed 25% of the city population. In recent times, religious demographics in Amsterdam have been changed by immigration from former colonies. Hinduism has been introduced from the Hindu diaspora from Suriname and several distinct branches of Islam have been brought from various parts of the world. Islam is now the largest non-Christian religion in Amsterdam. The large community of Ghanaian immigrants have established African churches, often in parking garages in the Bijlmer area. Diversity and immigration Amsterdam experienced an influx of religions and cultures after the Second World War. With 180 different nationalities, Amsterdam is home to one of the widest varieties of nationalities of any city in the world. The proportion of the population of immigrant origin in the city proper is about 50% and 88% of the population are Dutch citizens. Amsterdam has been one of the municipalities in the Netherlands which provided immigrants with extensive and free Dutch-language courses, which have benefited many immigrants. Cityscape and architecture Amsterdam fans out south from the Amsterdam Centraal station and Damrak, the main street off the station. The oldest area of the town is known as De Wallen (English: "The Quays"). It lies to the east of Damrak and contains the city's famous red-light district. To the south of De Wallen is the old Jewish quarter of Waterlooplein. The medieval and colonial age canals of Amsterdam, known as grachten, embraces the heart of the city where homes have interesting gables. Beyond the Grachtengordel are the former working-class areas of Jordaan and de Pijp. The Museumplein with the city's major museums, the Vondelpark, a 19th-century park named after the Dutch writer Joost van den Vondel, as well as the Plantage neighbourhood, with the zoo, are also located outside the Grachtengordel. Several parts of the city and the surrounding urban area are polders. This can be recognised by the suffix -meer which means lake, as in Aalsmeer, Bijlmermeer, Haarlemmermeer and Watergraafsmeer. Canals The Amsterdam canal system is the result of conscious city planning. In the early 17th century, when immigration was at a peak, a comprehensive plan was developed that was based on four concentric half-circles of canals with their ends emerging at the IJ bay. Known as the Grachtengordel, three of the canals were mostly for residential development: the Herengracht (where "Heren" refers to Heren Regeerders van de stad Amsterdam, ruling lords of Amsterdam, whilst gracht means canal, so that the name can be roughly translated as "Canal of the Lords"), Keizersgracht (Emperor's Canal) and Prinsengracht (Prince's Canal). The fourth and outermost canal is the Singelgracht, which is often not mentioned on maps because it is a collective name for all canals in the outer ring. The Singelgracht should not be confused with the oldest and innermost canal, the Singel. The canals served for defense, water management and transport. The defenses took the form of a moat and earthen dikes, with gates at transit points, but otherwise no masonry superstructures. The original plans have been lost, so historians, such as Ed Taverne, need to speculate on the original intentions: it is thought that the considerations of the layout were purely practical and defensive rather than ornamental. Construction started in 1613 and proceeded from west to east, across the breadth of the layout, like a gigantic windshield wiper as the historian Geert Mak calls it – and not from the centre outwards, as a popular myth has it. The canal construction in the southern sector was completed by 1656. Subsequently, the construction of residential buildings proceeded slowly. The eastern part of the concentric canal plan, covering the area between the Amstel river and the IJ bay, has never been implemented. In the following centuries, the land was used for parks, senior citizens' homes, theatres, other public facilities, and waterways without much planning. Over the years, several canals have been filled in, becoming streets or squares, such as the Nieuwezijds Voorburgwal and the Spui. Expansion After the development of Amsterdam's canals in the 17th century, the city did not grow beyond its borders for two centuries. During the 19th century, Samuel Sarphati devised a plan based on the grandeur of Paris and London at that time. The plan envisaged the construction of new houses, public buildings and streets just outside the Grachtengordel. The main aim of the plan, however, was to improve public health. Although the plan did not expand the city, it did produce some of the largest public buildings to date, like the Paleis voor Volksvlijt. Following Sarphati, civil engineers Jacobus van Niftrik and Jan Kalff designed an entire ring of 19th-century neighbourhoods surrounding the city's centre, with the city preserving the ownership of all land outside the 17th-century limit, thus firmly controlling development. Most of these neighbourhoods became home to the working class. In response to overcrowding, two plans were designed at the beginning of the 20th century which were very different from anything Amsterdam had ever seen before: Plan Zuid (designed by the architect Berlage) and West. These plans involved the development of new neighbourhoods consisting of housing blocks for all social classes. After the Second World War, large new neighbourhoods were built in the western, southeastern, and northern parts of the city. These new neighbourhoods were built to relieve the city's shortage of living space and give people affordable houses with modern conveniences. The neighbourhoods consisted mainly of large housing blocks located among green spaces, connected to wide roads, making the neighbourhoods easily accessible by motor car. The western suburbs which were built in that period are collectively called the Westelijke Tuinsteden. The area to the southeast of the city built during the same period is known as the Bijlmer. Architecture Amsterdam has a rich architectural history. The oldest building in Amsterdam is the Oude Kerk (English: Old Church), at the heart of the Wallen, consecrated in 1306. The oldest wooden building is Het Houten Huys at the Begijnhof. It was constructed around 1425 and is one of only two existing wooden buildings. It is also one of the few examples of Gothic architecture in Amsterdam. The oldest stone building of the Netherlands, The Moriaan is built in 's-Hertogenbosch. In the 16th century, wooden buildings were razed and replaced with brick ones. During this period, many buildings were constructed in the architectural style of the Renaissance. Buildings of this period are very recognisable with their stepped gable façades, which is the common Dutch Renaissance style. Amsterdam quickly developed its own Renaissance architecture. These buildings were built according to the principles of the architect Hendrick de Keyser. One of the most striking buildings designed by Hendrick de Keyser is the Westerkerk. In the 17th century baroque architecture became very popular, as it was elsewhere in Europe. This roughly coincided with Amsterdam's Golden Age. The leading architects of this style in Amsterdam were Jacob van Campen, Philips Vingboons and Daniel Stalpaert. Philip Vingboons designed splendid merchants' houses throughout the city. A famous building in baroque style in Amsterdam is the Royal Palace on Dam Square. Throughout the 18th century, Amsterdam was heavily influenced by French culture. This is reflected in the architecture of that period. Around 1815, architects broke with the baroque style and started building in different neo-styles. Most Gothic style buildings date from that era and are therefore said to be built in a neo-gothic style. At the end of the 19th century, the Jugendstil or Art Nouveau style became popular and many new buildings were constructed in this architectural style. Since Amsterdam expanded rapidly during this period, new buildings adjacent to the city centre were also built in this style. The houses in the vicinity of the Museum Square in Amsterdam Oud-Zuid are an example of Jugendstil. The last style that was popular in Amsterdam before the modern era was Art Deco. Amsterdam had its own version of the style, which was called the Amsterdamse School. Whole districts were built this style, such as the Rivierenbuurt. A notable feature of the façades of buildings designed in Amsterdamse School is that they are highly decorated and ornate, with oddly shaped windows and doors. The old city centre is the focal point of all the architectural styles before the end of the 19th century. Jugendstil and Georgian are mostly found outside the city's centre in the neighbourhoods built in the early 20th century, although there are also some striking examples of these styles in the city centre. Most historic buildings in the city centre and nearby are houses, such as the famous merchants' houses lining the canals. Parks and recreational areas Amsterdam has many parks, open spaces, and squares throughout the city. The Vondelpark, the largest park in the city, is located in the Oud-Zuid neighbourhood and is named after the 17th-century Amsterdam author Joost van den Vondel. Yearly, the park has around 10 million visitors. In the park is an open-air theatre, a playground and several horeca facilities. In the Zuid borough, is the Beatrixpark, named after Queen Beatrix. Between Amsterdam and Amstelveen is the Amsterdamse Bos ("Amsterdam Forest"), the largest recreational area in Amsterdam. Annually, almost 4.5 million people visit the park, which has a size of 1.000 hectares and is approximately three times the size of Central Park. The Amstelpark in the Zuid borough houses the Rieker windmill, which dates to 1636. Other parks include the Sarphatipark in the De Pijp neighbourhood, the Oosterpark in the Oost borough and the Westerpark in the Westerpark neighbourhood. The city has three beaches: Nemo Beach, Citybeach "Het stenen hoofd" (Silodam) and Blijburg, all located in the Centrum borough. The city has many open squares (plein in Dutch). The namesake of the city as the site of the original dam, Dam Square, is the main city square and has the Royal Palace and National Monument. Museumplein hosts various museums, including the , Van Gogh Museum, and Stedelijk Museum. Other squares include Rembrandtplein, Muntplein, Nieuwmarkt, Leidseplein, Spui and Waterlooplein. Also, near to Amsterdam is the Nekkeveld estate conservation project. Economy Amsterdam is the financial and business capital of the Netherlands. According to the 2007 European Cities Monitor (ECM) – an annual location survey of Europe's leading companies carried out by global real estate consultant Cushman & Wakefield – Amsterdam is one of the top European cities in which to locate an international business, ranking fifth in the survey. with the survey determining London, Paris, Frankfurt and Barcelona as the four European cities surpassing Amsterdam in this regard. A substantial number of large corporations and banks' headquarters are located in the Amsterdam area, including: AkzoNobel, Heineken International, ING Group, ABN AMRO, TomTom, Delta Lloyd Group, Booking.com and Philips. Although many small offices remain along the historic canals, centrally based companies have increasingly relocated outside Amsterdam's city centre. Consequently, the Zuidas (English: South Axis) has become the new financial and legal hub of Amsterdam, with the country's five largest law firms and several subsidiaries of large consulting firms, such as Boston Consulting Group and Accenture, as well as the World Trade Centre (Amsterdam) located in the Zuidas district. In addition to the Zuidas, there are three smaller financial districts in Amsterdam: around Amsterdam Sloterdijk railway station. Where one can find the offices of several newspapers, such as De Telegraaf. as well as those of Deloitte, the Gemeentelijk Vervoerbedrijf (municipal public transport company), and the Dutch tax offices (Belastingdienst); around the Johan Cruyff Arena in Amsterdam Zuidoost, with the headquarters of ING Group; around the Amstel railway station in the Amsterdam-Oost district to the east of the historical city. Amsterdam's tallest building, the Rembrandt Tower, is located here. As are the headquarters of Philips, the Dutch multinational conglomerate. Amsterdam has been a leading city to reduce the use of raw materials and has created a plan to become a circular city by 2050. The adjoining municipality of Amstelveen is the location of KPMG International's global headquarters. Other non-Dutch companies have chosen to settle in communities surrounding Amsterdam since they allow freehold property ownership, whereas Amsterdam retains ground rent. The Amsterdam Stock Exchange (AEX), now part of Euronext, is the world's oldest stock exchange and, due to Brexit, has overtaken LSE as the largest bourse in Europe. It is near Dam Square in the city centre. Port of Amsterdam The Port of Amsterdam is the fourth-largest port in Europe, the 38th largest port in the world and the second-largest port in the Netherlands by metric tons of cargo. In 2014, the Port of Amsterdam had a cargo throughput of 97,4 million tons of cargo, which was mostly bulk cargo. Amsterdam has the biggest cruise port in the Netherlands with more than 150 cruise ships every year. In 2019, the new lock in IJmuiden opened; since then, the port has been able to grow to 125 million tonnes in capacity. Tourism Amsterdam is one of the most popular tourist destinations in Europe, receiving more than 5.34 million international visitors annually; this is excluding the 16 million day-trippers visiting the city every year. The number of visitors has been growing steadily over the past decade. This can be attributed to an increasing number of European visitors. Two-thirds of the hotels are located in the city's centre. Hotels with 4 or 5 stars contribute 42% of the total beds available and 41% of the overnight stays in Amsterdam. The room occupation rate was 85% in 2017, up from 78% in 2006. The majority of tourists (74%) originate from Europe. The largest group of non-European visitors come from the United States, accounting for 14% of the total. Certain years have a theme in Amsterdam to attract extra tourists. For example, the year 2006 was designated "Rembrandt 400", to celebrate the 400th birthday of Rembrandt van Rijn. Some hotels offer special arrangements or activities during these years. The average number of guests per year staying at the four campsites around the city range from 12,000 to 65,000. De Wallen (red-light district) De Wallen, also known as Walletjes or Rosse Buurt, is a designated area for legalised prostitution and is Amsterdam's largest and best-known red-light district. This neighbourhood has become a famous attraction for tourists. It consists of a network of canals, streets, and alleys containing several hundred small, one-room apartments rented by sex workers who offer their services from behind a window or glass door, typically illuminated with red lights. In recent years, the city government has been closing and repurposing the famous red-light district windows in an effort to clean up the area and reduce the amount of party and sex tourism. Retail Shops in Amsterdam range from large high-end department stores such as De Bijenkorf founded in 1870 to small speciality shops. Amsterdam's high-end shops are found in the streets P.C. Hooftstraat and Cornelis Schuytstraat, which are located in the vicinity of the Vondelpark. One of Amsterdam's busiest high streets is the narrow, medieval Kalverstraat in the heart of the city. Other shopping areas include the Negen Straatjes and Haarlemmerdijk and Haarlemmerstraat. Negen Straatjes are nine narrow streets within the Grachtengordel, the concentric canal system of Amsterdam. The Negen Straatjes differ from other shopping districts with the presence of a large diversity of privately owned shops. The Haarlemmerstraat and Haarlemmerdijk were voted best shopping street in the Netherlands in 2011. These streets have as the Negen Straatjes a large diversity of privately owned shops. However, as the Negen Straatjes are dominated by fashion stores, the Haarlemmerstraat and Haarlemmerdijk offer a wide variety of stores, just to name some specialities: candy and other food-related stores, lingerie, sneakers, wedding clothing, interior shops, books, Italian deli's, racing and mountain bikes, skatewear, etc. The city also features a large number of open-air markets such as the Albert Cuyp Market, Westerstraat-markt, Ten Katemarkt, and Dappermarkt. Some of these markets are held daily, like the Albert Cuypmarkt and the Dappermarkt. Others, like the Westerstraatmarkt, are held every week. Fashion Several fashion brands and designers are based in Amsterdam. Fashion designers include Iris van Herpen, Mart Visser, Viktor & Rolf, Marlies Dekkers and Frans Molenaar. Fashion models like Yfke Sturm, Doutzen Kroes and Kim Noorda started their careers in Amsterdam. Amsterdam has its garment centre in the World Fashion Center. Fashion photographers Inez van Lamsweerde and Vinoodh Matadin were born in Amsterdam. Culture During the later part of the 16th century, Amsterdam's Rederijkerskamer (Chamber of rhetoric) organised contests between different Chambers in the reading of poetry and drama. In 1637, Schouwburg, the first theatre in Amsterdam was built, opening on 3 January 1638. The first ballet performances in the Netherlands were given in Schouwburg in 1642 with the Ballet of the Five Senses. In the 18th century, French theatre became popular. While Amsterdam was under the influence of German music in the 19th century there were few national opera productions; the Hollandse Opera of Amsterdam was built in 1888 for the specific purpose of promoting Dutch opera. In the 19th century, popular culture was centred on the Nes area in Amsterdam (mainly vaudeville and music-hall). An improved metronome was invented in 1812 by Dietrich Nikolaus Winkel. The (1885) and Stedelijk Museum (1895) were built and opened. In 1888, the Concertgebouworkest orchestra was established. With the 20th century came cinema, radio and television. Though most studios are located in Hilversum and Aalsmeer, Amsterdam's influence on programming is very strong. Many people who work in the television industry live in Amsterdam. Also, the headquarters of the Dutch SBS Broadcasting Group is located in Amsterdam. Museums The most important museums of Amsterdam are located on the Museumplein (Museum Square), located at the southwestern side of the Rijksmuseum. It was created in the last quarter of the 19th century on the grounds of the former World's fair. The northeastern part of the square is bordered by the large Rijksmuseum. In front of the Rijksmuseum on the square itself is a long, rectangular pond. This is transformed into an ice rink in winter. The northwestern part of the square is bordered by the Van Gogh Museum, House of Bols Cocktail & Genever Experience and Coster Diamonds. The southwestern border of the Museum Square is the Van Baerlestraat, which is a major thoroughfare in this part of Amsterdam. The Concertgebouw is located across this street from the square. To the southeast of the square are several large houses, one of which contains the American consulate. A parking garage can be found underneath the square, as well as a supermarket. The Museumplein is covered almost entirely with a lawn, except for the northeastern part of the square which is covered with gravel. The current appearance of the square was realised in 1999, when the square was remodelled. The square itself is the most prominent site in Amsterdam for festivals and outdoor concerts, especially in the summer. Plans were made in 2008 to remodel the square again because many inhabitants of Amsterdam are not happy with its current appearance. The possesses the largest and most important collection of classical Dutch art. It opened in 1885. Its collection consists of nearly one million objects. The artist most associated with Amsterdam is Rembrandt, whose work, and the work of his pupils, is displayed in the Rijksmuseum. Rembrandt's masterpiece The Night Watch is one of the top pieces of art of the museum. It also houses paintings from artists like Bartholomeus van der Helst, Johannes Vermeer, Frans Hals, Ferdinand Bol, Albert Cuyp, Jacob van Ruisdael and Paulus Potter. Aside from paintings, the collection consists of a large variety of decorative art. This ranges from Delftware to giant doll-houses from the 17th century. The architect of the gothic revival building was P.J.H. Cuypers. The museum underwent a 10-year, 375 million euro renovation starting in 2003. The full collection was reopened to the public on 13 April 2013 and the Rijksmuseum has remained the most visited museum in Amsterdam with 2.2 million visitors in 2016 and 2.16 million in 2017. Van Gogh lived in Amsterdam for a short while and there is a museum dedicated to his work. The museum is housed in one of the few modern buildings in this area of Amsterdam. The building was designed by Gerrit Rietveld. This building is where the permanent collection is displayed. A new building was added to the museum in 1999. This building, known as the performance wing, was designed by Japanese architect Kisho Kurokawa. Its purpose is to house temporary exhibitions of the museum. Some of Van Gogh's most famous paintings, like The Potato Eaters and Sunflowers, are in the collection. The Van Gogh museum is the second most visited museum in Amsterdam, not far behind the Rijksmuseum in terms of the number of visits, being approximately 2.1 million in 2016, for example. Next to the Van Gogh museum stands the Stedelijk Museum. This is Amsterdam's most important museum of modern art. The museum is as old as the square it borders and was opened in 1895. The permanent collection consists of works of art from artists like Piet Mondrian, Karel Appel, and Kazimir Malevich. After renovations lasting several years, the museum opened in September 2012 with a new composite extension that has been called 'The Bathtub' due to its resemblance to one. Amsterdam contains many other museums throughout the city. They range from small museums such as the Verzetsmuseum (Resistance Museum), the Anne Frank House, and the Rembrandt House Museum, to the very large, like the Tropenmuseum (Museum of the Tropics), Amsterdam Museum (formerly known as Amsterdam Historical Museum), Hermitage Amsterdam (a dependency of the Hermitage Museum in Saint Petersburg) and the Joods Historisch Museum (Jewish Historical Museum). The modern-styled Nemo is dedicated to child-friendly science exhibitions. Music Amsterdam's musical culture includes a large collection of songs that treat the city nostalgically and lovingly. The 1949 song "Aan de Amsterdamse grachten" ("On the canals of Amsterdam") was performed and recorded by many artists, including John Kraaijkamp Sr.; the best-known version is probably that by Wim Sonneveld (1962). In the 1950s Johnny Jordaan rose to fame with "Geef mij maar Amsterdam" ("I prefer Amsterdam"), which praises the city above all others (explicitly Paris); Jordaan sang especially about his own neighbourhood, the Jordaan ("Bij ons in de Jordaan"). Colleagues and contemporaries of Johnny include Tante Leen and Manke Nelis. Another notable Amsterdam song is "Amsterdam" by Jacques Brel (1964). A 2011 poll by Amsterdam newspaper Het Parool that Trio Bier's "Oude Wolf" was voted "Amsterdams lijflied". Notable Amsterdam bands from the modern era include the Osdorp Posse and The Ex. AFAS Live (formerly known as the Heineken Music Hall) is a concert hall located near the Johan Cruyff Arena (known as the Amsterdam Arena until 2018). Its main purpose is to serve as a podium for pop concerts for big audiences. Many famous international artists have performed there. Two other notable venues, Paradiso and the are located near the Leidseplein. Both focus on broad programming, ranging from indie rock to hip hop, R&B, and other popular genres. Other more subcultural music venues are OCCII, OT301, De Nieuwe Anita, Winston Kingdom, and Zaal 100. Jazz has a strong following in Amsterdam, with the Bimhuis being the premier venue. In 2012, Ziggo Dome was opened, also near Amsterdam Arena, a state-of-the-art indoor music arena. AFAS Live is also host to many electronic dance music festivals, alongside many other venues. Armin van Buuren and Tiesto, some of the worlds leading Trance DJ's hail from the Netherlands and frequently perform in Amsterdam. Each year in October, the city hosts the Amsterdam Dance Event (ADE) which is one of the leading electronic music conferences and one of the biggest club festivals for electronic music in the world, attracting over 350,000 visitors each year. Another popular dance festival is 5daysoff, which takes place in the venues Paradiso and . In the summertime, there are several big outdoor dance parties in or nearby Amsterdam, such as Awakenings, Dance Valley, Mystery Land, Loveland, A Day at the Park, Welcome to the Future, and Valtifest. Amsterdam has a world-class symphony orchestra, the Royal Concertgebouw Orchestra. Their home is the , which is across the Van Baerlestraat from the Museum Square. It is considered by critics to be a concert hall with some of the best acoustics in the world. The building contains three halls, Grote Zaal, Kleine Zaal, and Spiegelzaal. Some nine hundred concerts and other events per year take place in the Concertgebouw, for a public of over 700,000, making it one of the most-visited concert halls in the world. The opera house of Amsterdam is located adjacent to the city hall. Therefore, the two buildings combined are often called the Stopera, (a word originally coined by protesters against it very construction: Stop the Opera[-house]). This huge modern complex, opened in 1986, lies in the former Jewish neighbourhood at Waterlooplein next to the river Amstel. The Stopera is the home base of Dutch National Opera, Dutch National Ballet and the Holland Symfonia. Muziekgebouw aan 't IJ is a concert hall, which is located in the IJ near the central station. Its concerts perform mostly modern classical music. Located adjacent to it, is the Bimhuis, a concert hall for improvised and Jazz music. Performing arts Amsterdam has three main theatre buildings. The Stadsschouwburg at the Leidseplein is the home base of Toneelgroep Amsterdam. The current building dates from 1894. Most plays are performed in the Grote Zaal (Great Hall). The normal program of events encompasses all sorts of theatrical forms. In 2009, the new hall of the Stadsschouwburg Amsterdam, Toneelgroep Amsterdam and Melkweg opened, and the renovation of the front end of the theatre was ready. The Dutch National Opera and Ballet (formerly known as Het Muziektheater), dating from 1986, is the principal opera house and home to Dutch National Opera and Dutch National Ballet. Royal Theatre Carré was built as a permanent circus theatre in 1887 and is currently mainly used for musicals, cabaret performances, and pop concerts. The recently re-opened DeLaMar Theater houses more commercial plays and musicals. A new theatre has also moved into the Amsterdam scene in 2014, joining other established venues: Theater Amsterdam is located in the west part of Amsterdam, on the Danzigerkade. It is housed in a modern building with a panoramic view over the harbour. The theatre is the first-ever purpose-built venue to showcase a single play entitled ANNE, the play based on Anne Frank's life. On the east side of town, there is a small theatre in a converted bathhouse, the Badhuistheater. The theatre often has English programming. The Netherlands has a tradition of cabaret or kleinkunst, which combines music, storytelling, commentary, theatre and comedy. Cabaret dates back to the 1930s and artists like Wim Kan, Wim Sonneveld and Toon Hermans were pioneers of this form of art in the Netherlands. In Amsterdam is the Kleinkunstacademie (English: Cabaret Academy) and Nederlied Kleinkunstkoor (English: Cabaret Choir). Contemporary popular artists are Youp van 't Hek, Freek de Jonge, Herman Finkers, Hans Teeuwen, Theo Maassen, Herman van Veen, Najib Amhali, Raoul Heertje, Jörgen Raymann, Brigitte Kaandorp and Comedytrain. The English spoken comedy scene was established with the founding of Boom Chicago in 1993. They have their own theatre at Leidseplein. Nightlife Amsterdam is famous for its vibrant and diverse nightlife. Amsterdam has many cafés (bars). They range from large and modern to small and cosy. The typical Bruine Kroeg (brown café) breathe a more old fashioned atmosphere with dimmed lights, candles, and somewhat older clientele. These brown cafés mostly offer a wide range of local and international artisanal beers. Most cafés have terraces in summertime. A common sight on the Leidseplein during summer is a square full of terraces packed with people drinking beer or wine. Many restaurants can be found in Amsterdam as well. Since Amsterdam is a multicultural city, a lot of different ethnic restaurants can be found. Restaurants range from being rather luxurious and expensive to being ordinary and affordable. Amsterdam also possesses many discothèques. The two main nightlife areas for tourists are the Leidseplein and the Rembrandtplein. The Paradiso, and Sugar Factory are cultural centres, which turn into discothèques on some nights. Examples of discothèques near the Rembrandtplein are the Escape, Air, John Doe and Club Abe. Also noteworthy are Panama, Hotel Arena (East), TrouwAmsterdam and Studio 80. In recent years '24-hour' clubs opened their doors, most notably Radion De School, Shelter and Marktkantine. Bimhuis located near the Central Station, with its rich programming hosting the best in the field is considered one of the best jazz clubs in the world. The Reguliersdwarsstraat is the main street for the LGBT community and nightlife. Festivals In 2008, there were 140 festivals and events in Amsterdam. During the same year, Amsterdam was designated as the World Book Capital for one year by UNESCO. Famous festivals and events in Amsterdam include: Koningsdag (which was named Koninginnedag until the crowning of King Willem-Alexander in 2013) (King's Day – Queen's Day); the Holland Festival for the performing arts; the yearly Prinsengrachtconcert (classical concerto on the Prinsen canal) in August; the 'Stille Omgang' (a silent Roman Catholic evening procession held every March); Amsterdam Gay Pride; The Cannabis Cup; and the Uitmarkt. On Koningsdag—that is held each year on 27 April—hundreds of thousands of people travel to Amsterdam to celebrate with the city's residents. The entire city becomes overcrowded with people buying products from the freemarket, or visiting one of the many music concerts. The yearly Holland Festival attracts international artists and visitors from all over Europe. Amsterdam Gay Pride is a yearly local LGBT parade of boats in Amsterdam's canals, held on the first Saturday in August. The annual Uitmarkt is a three-day cultural event at the start of the cultural season in late August. It offers previews of many different artists, such as musicians and poets, who perform on podia. Sports Amsterdam is home of the Eredivisie football club AFC Ajax. The stadium Johan Cruyff Arena is the home of Ajax. It is located in the south-east of the city next to the new Amsterdam Bijlmer ArenA railway station. Before moving to their current location in 1996, Ajax played their regular matches in the now demolished De Meer Stadion in the eastern part of the city or in the Olympic Stadium. In 1928, Amsterdam hosted the Summer Olympics. The Olympic Stadium built for the occasion has been completely restored and is now used for cultural and sporting events, such as the Amsterdam Marathon. In 1920, Amsterdam assisted in hosting some of the sailing events for the Summer Olympics held in neighbouring Antwerp, Belgium by hosting events at Buiten IJ. The city holds the Dam to Dam Run, a race from Amsterdam to Zaandam, as well as the Amsterdam Marathon. The ice hockey team Amstel Tijgers play in the Jaap Eden ice rink. The team competes in the Dutch ice hockey premier league. Speed skating championships have been held on the 400-meter lane of this ice rink. Amsterdam holds two American football franchises: the Amsterdam Crusaders and the Amsterdam Panthers. The Amsterdam Pirates baseball team competes in the Dutch Major League. There are three field hockey teams: Amsterdam, Pinoké and Hurley, who play their matches around the Wagener Stadium in the nearby city of Amstelveen. The basketball team MyGuide Amsterdam competes in the Dutch premier division and play their games in the Sporthallen Zuid. There is one rugby club in Amsterdam, which also hosts sports training classes such as RTC (Rugby Talenten Centrum or Rugby Talent Centre) and the National Rugby stadium. Since 1999, the city of Amsterdam honours the best sportsmen and women at the Amsterdam Sports Awards. Boxer Raymond Joval and field hockey midfielder Carole Thate were the first to receive the awards, in 1999. Amsterdam hosted the World Gymnaestrada in 1991 and will do so again in 2023. Politics The city of Amsterdam is a municipality under the Dutch Municipalities Act. It is governed by a directly elected municipal council, a municipal executive board and a mayor. Since 1981, the municipality of Amsterdam has gradually been divided into semi-autonomous boroughs, called stadsdelen or 'districts'. Over time, a total of 15 boroughs were created. In May 2010, under a major reform, the number of Amsterdam boroughs was reduced to eight: Amsterdam-Centrum covering the city centre including the canal belt, Amsterdam-Noord consisting of the neighbourhoods north of the IJ lake, Amsterdam-Oost in the east, Amsterdam-Zuid in the south, Amsterdam-West in the west, Amsterdam Nieuw-West in the far west, Amsterdam Zuidoost in the southeast, and Westpoort covering the Port of Amsterdam area. City government As with all Dutch municipalities, Amsterdam is governed by a directly elected municipal council, a municipal executive board and a government appointed mayor (burgemeester). The mayor is a member of the municipal executive board, but also has individual responsibilities in maintaining public order. On 27 June 2018, Femke Halsema (former member of House of Representatives for GroenLinks from 1998 to 2011) was appointed as the first woman to be Mayor of Amsterdam by the King's Commissioner of North Holland for a six-year term after being nominated by the Amsterdam municipal council and began serving a six-year term on 12 July 2018. She replaces Eberhard van der Laan (Labour Party) who was the Mayor of Amsterdam from 2010 until his death in October 2017. After the 2014 municipal council elections, a governing majority of D66, VVD and SP was formed – the first coalition without the Labour Party since World War II. Next to the Mayor, the municipal executive board consists of eight wethouders ('alderpersons') appointed by the municipal council: four D66 alderpersons, two VVD alderpersons and two SP alderpersons. On 18 September 2017, it was announced by Eberhard van der Laan in an open letter to Amsterdam citizens that Kajsa Ollongren would take up his office as acting Mayor of Amsterdam with immediate effect due to ill health. Ollongren was succeeded as acting Mayor by Eric van der Burg on 26 October 2017 and by Jozias van Aartsen on 4 December 2017. Unlike most other Dutch municipalities, Amsterdam is subdivided into eight boroughs, called stadsdelen or 'districts', and the urban area of Weesp, a system that was implemented gradually in the 1980s to improve local governance. The boroughs are responsible for many activities that had previously been run by the central city. In 2010, the number of Amsterdam boroughs reached fifteen. Fourteen of those had their own district council (deelraad), elected by a popular vote. The fifteenth, Westpoort, covers the harbour of Amsterdam and had very few residents. Therefore, it was governed by the central municipal council. Under the borough system, municipal decisions are made at borough level, except for those affairs pertaining to the whole city such as major infrastructure projects, which are the jurisdiction of the central municipal authorities. In 2010, the borough system was restructured, in which many smaller boroughs merged into larger boroughs. In 2014, under a reform of the Dutch Municipalities Act, the Amsterdam boroughs lost much of their autonomous status, as their district councils were abolished. The municipal council of Amsterdam voted to maintain the borough system by replacing the district councils with smaller, but still directly elected district committees (bestuurscommissies). Under a municipal ordinance, the new district committees were granted responsibilities through delegation of regulatory and executive powers by the central municipal council. Metropolitan area "Amsterdam" is usually understood to refer to the municipality of Amsterdam. Colloquially, some areas within the municipality, such as the town of Durgerdam, may not be considered part of Amsterdam. Statistics Netherlands uses three other definitions of Amsterdam: metropolitan agglomeration Amsterdam (Grootstedelijke Agglomeratie Amsterdam, not to be confused with Grootstedelijk Gebied Amsterdam, a synonym of Groot Amsterdam), Greater Amsterdam (Groot Amsterdam, a COROP region) and the urban region Amsterdam (Stadsgewest Amsterdam). The Amsterdam Department for Research and Statistics uses a fourth conurbation, namely the Stadsregio Amsterdam ('City Region of Amsterdam'). The city region is similar to Greater Amsterdam but includes the municipalities of Zaanstad and Wormerland. It excludes Graft-De Rijp. The smallest of these areas is the municipality of Amsterdam with a population of 802,938 in 2013. The conurbation had a population of 1,096,042 in 2013. It includes the municipalities of Zaanstad, Wormerland, Oostzaan, Diemen and Amstelveen only, as well as the municipality of Amsterdam. Greater Amsterdam includes 15 municipalities, and had a population of 1,293,208 in 2013. Though much larger in area, the population of this area is only slightly larger, because the definition excludes the relatively populous municipality of Zaanstad. The largest area by population, the Amsterdam Metropolitan Area (Dutch: Metropoolregio Amsterdam), has a population of 2,33 million. It includes for instance Zaanstad, Wormerland, Muiden, Abcoude, Haarlem, Almere and Lelystad but excludes Graft-De Rijp. Amsterdam is part of the conglomerate metropolitan area Randstad, with a total population of 6,659,300 inhabitants. Of these various metropolitan area configurations, only the Stadsregio Amsterdam (City Region of Amsterdam) has a formal governmental status. Its responsibilities include regional spatial planning and the metropolitan public transport concessions. National capital Under the Dutch Constitution, Amsterdam is the capital of the Netherlands. Since the 1983 constitutional revision, the constitution mentions "Amsterdam" and "capital" in chapter 2, article 32: The king's confirmation by oath and his coronation take place in "the capital Amsterdam" ("de hoofdstad Amsterdam"). Previous versions of the constitution only mentioned "the city of Amsterdam" ("de stad Amsterdam"). For a royal investiture, therefore, the States General of the Netherlands (the Dutch Parliament) meets for a ceremonial joint session in Amsterdam. The ceremony traditionally takes place at the Nieuwe Kerk on Dam Square, immediately after the former monarch has signed the act of abdication at the nearby Royal Palace of Amsterdam. Normally, however, the Parliament sits in The Hague, the city which has historically been the seat of the Dutch government, the Dutch monarchy, and the Dutch supreme court. Foreign embassies are also located in The Hague. Symbols The coat of arms of Amsterdam is composed of several historical elements. First and centre are three St Andrew's crosses, aligned in a vertical band on the city's shield (although Amsterdam's patron saint was Saint Nicholas). These St Andrew's crosses can also be found on the city shields of neighbours Amstelveen and Ouder-Amstel. This part of the coat of arms is the basis of the flag of Amsterdam, flown by the city government, but also as civil ensign for ships registered in Amsterdam. Second is the Imperial Crown of Austria. In 1489, out of gratitude for services and loans, Maximilian I awarded Amsterdam the right to adorn its coat of arms with the king's crown. Then, in 1508, this was replaced with Maximilian's imperial crown when he was crowned Holy Roman Emperor. In the early years of the 17th century, Maximilian's crown in Amsterdam's coat of arms was again replaced, this time with the crown of Emperor Rudolph II, a crown that became the Imperial Crown of Austria. The lions date from the late 16th century, when city and province became part of the Republic of the Seven United Netherlands. Last came the city's official motto: Heldhaftig, Vastberaden, Barmhartig ("Heroic, Determined, Merciful"), bestowed on the city in 1947 by Queen Wilhelmina, in recognition of the city's bravery during the Second World War. Transport Metro, tram and bus Currently, there are sixteen tram routes and five metro routes. All are operated by municipal public transport operator Gemeentelijk Vervoerbedrijf (GVB), which also runs the city bus network. Four fare-free GVB ferries carry pedestrians and cyclists across the IJ lake to the borough of Amsterdam-Noord, and two fare-charging ferries run east and west along the harbour. There are also privately operated water taxis, a water bus, a boat sharing operation, electric rental boats and canal cruises, that transport people along Amsterdam's waterways. Regional buses, and some suburban buses, are operated by Connexxion and EBS. International coach services are provided by Eurolines from Amsterdam Amstel railway station, IDBUS from Amsterdam Sloterdijk railway station, and Megabus from the Zuiderzeeweg in the east of the city. In order to facilitate easier transport to the centre of Amsterdam, the city has various P+R Locations where people can park their car at an affordable price and transfer to one of the numerous public transport lines. Car Amsterdam was intended in 1932 to be the hub, a kind of Kilometre Zero, of the highway system of the Netherlands, with freeways numbered One to Eight planned to originate from the city. The outbreak of the Second World War and shifting priorities led to the current situation, where only roads A1, A2, and A4 originate from Amsterdam according to the original plan. The A3 to Rotterdam was cancelled in 1970 in order to conserve the Groene Hart. Road A8, leading north to Zaandam and the A10 Ringroad were opened between 1968 and 1974. Besides the A1, A2, A4 and A8, several freeways, such as the A7 and A6, carry traffic mainly bound for Amsterdam. The A10 ringroad surrounding the city connects Amsterdam with the Dutch national network of freeways. Interchanges on the A10 allow cars to enter the city by transferring to one of the 18 city roads, numbered S101 through to S118. These city roads are regional roads without grade separation, and sometimes without a central reservation. Most are accessible by cyclists. The S100 Centrumring is a smaller ringroad circumnavigating the city's centre. In the city centre, driving a car is discouraged. Parking fees are expensive, and many streets are closed to cars or are one-way. The local government sponsors carsharing and carpooling initiatives such as Autodelen and Meerijden.nu. The local government has also started removing parking spaces in the city, with the goal of removing 10,000 spaces (roughly 1,500 per year) by 2025. National rail Amsterdam is served by ten stations of the Nederlandse Spoorwegen (Dutch Railways). Five are intercity stops: Sloterdijk, Zuid, Amstel, Bijlmer ArenA and Amsterdam Centraal. The stations for local services are: Lelylaan, RAI, Holendrecht, Muiderpoort and Science Park. Amsterdam Centraal is also an international railway station. From the station there are regular services to destinations such as Austria, Belarus, Belgium, Czech Republic, Denmark, France, Germany, Hungary, Poland, Russia, Switzerland and the United Kingdom. Among these trains are international trains of the Nederlandse Spoorwegen (Amsterdam-Berlin), the Eurostar (Amsterdam-Brussels-London), Thalys (Amsterdam-Brussels-Paris/Lille), and Intercity-Express (Amsterdam–Cologne–Frankfurt). Airport Amsterdam Airport Schiphol is less than 20 minutes by train from Amsterdam Centraal station and is served by domestic and international intercity trains, such as Thalys, Eurostar and Intercity Brussel. Schiphol is the largest airport in the Netherlands, the third-largest in Europe, and the 14th-largest in the world in terms of passengers. It handles over 68 million passengers per year and is the home base of four airlines, KLM, Transavia, Martinair and Arkefly. , Schiphol was the fifth busiest airport in the world measured by international passenger numbers. This airport is 4 meters below sea level. Although Schiphol is internationally known as Amsterdam Schiphol Airport it actually lies in the neighbouring municipality of Haarlemmermeer, southwest of the city. Cycling Amsterdam is one of the most bicycle-friendly large cities in the world and is a centre of bicycle culture with good facilities for cyclists such as bike paths and bike racks, and several guarded bike storage garages (fietsenstalling) which can be used. According to the most recent figures published by Central Bureau of Statistics (CBS), in 2015 the 442.693 households (850.000 residents) in Amsterdam together owned 847.000 bicycles – 1.91 bicycle per household. Theft is widespreadin 2011, about 83,000 bicycles were stolen in Amsterdam. Bicycles are used by all socio-economic groups because of their convenience, Amsterdam's small size, the of bike paths, the flat terrain, and the inconvenience of driving an automobile. Education Amsterdam has two universities: the University of Amsterdam (Universiteit van Amsterdam, UvA), and the Vrije Universiteit Amsterdam (VU). Other institutions for higher education include an art school – Gerrit Rietveld Academie, a university of applied sciences – the Hogeschool van Amsterdam, and the Amsterdamse Hogeschool voor de Kunsten. Amsterdam's International Institute of Social History is one of the world's largest documentary and research institutions concerning social history, and especially the history of the labour movement. Amsterdam's Hortus Botanicus, founded in the early 17th century, is one of the oldest botanical gardens in the world, with many old and rare specimens, among them the coffee plant that served as the parent for the entire coffee culture in Central and South America. There are over 200 primary schools in Amsterdam. Some of these primary schools base their teachings on particular pedagogic theories like the various Montessori schools. The biggest Montessori high school in Amsterdam is the Montessori Lyceum Amsterdam. Many schools, however, are based on religion. This used to be primarily Roman Catholicism and various Protestant denominations, but with the influx of Muslim immigrants, there has been a rise in the number of Islamic schools. Jewish schools can be found in the southern suburbs of Amsterdam. Amsterdam is noted for having five independent grammar schools (Dutch: gymnasia), the Vossius Gymnasium, Barlaeus Gymnasium, St. Ignatius Gymnasium, Het 4e Gymnasium and the Cygnus Gymnasium where a classical curriculum including Latin and classical Greek is taught. Though believed until recently by many to be an anachronistic and elitist concept that would soon die out, the gymnasia have recently experienced a revival, leading to the formation of a fourth and fifth grammar school in which the three aforementioned schools participate. Most secondary schools in Amsterdam offer a variety of different levels of education in the same school. The city also has various colleges ranging from art and design to politics and economics which are mostly also available for students coming from other countries. Schools for foreign nationals in Amsterdam include the Amsterdam International Community School, British School of Amsterdam, Albert Einstein International School Amsterdam, Lycée Vincent van Gogh La Haye-Amsterdam primary campus (French school), International School of Amsterdam, and the Japanese School of Amsterdam. Notable people Media Amsterdam is a prominent centre for national and international media. Some locally based newspapers include Het Parool, a national daily paper; De Telegraaf, the largest Dutch daily newspaper; the daily newspapers Trouw, de Volkskrant and NRC; De Groene Amsterdammer, a weekly newspaper; the free newspapers Metro and The Holland Times (printed in English). Amsterdam is home to the second-largest Dutch commercial TV group SBS Broadcasting Group, consisting of TV-stations SBS 6, Net 5 and Veronica. However, Amsterdam is not considered 'the media city of the Netherlands'. The town of Hilversum, south-east of Amsterdam, has been crowned with this unofficial title. Hilversum is the principal centre for radio and television broadcasting in the Netherlands. Radio Netherlands, heard worldwide via shortwave radio since the 1920s, is also based there. Hilversum is home to an extensive complex of audio and television studios belonging to the national broadcast production company NOS, as well as to the studios and offices of all the Dutch public broadcasting organisations and many commercial TV production companies. In 2012, the music video of Far East Movement, 'Live My Life', was filmed in various parts of Amsterdam. Also, several movies were filmed in Amsterdam, such as James Bond's Diamonds Are Forever, Ocean's Twelve, Girl with a Pearl Earring and The Hitman's Bodyguard. Amsterdam is also featured in John Green's book The Fault in Our Stars, which has been made into a film as well that partly takes place in Amsterdam. Housing From the late 1960s onwards many buildings in Amsterdam have been squatted both for housing and for using as social centres. A number of these squats have legalised and become well known, such as OCCII, OT301, Paradiso and Vrankrijk.

Audi

Audi AG () is a German automotive manufacturer of luxury vehicles headquartered in Ingolstadt, Bavaria, Germany. As a subsidiary of its parent company, the Volkswagen Group, Audi produces vehicles in nine production facilities worldwide. The origins of the company are complex, going back to the early 20th century and the initial enterprises (Horch and the Audiwerke) founded by engineer August Horch (1868–1951); and two other manufacturers (DKW and Wanderer), leading to the foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz. After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present-day form of the company. The company name is based on the Latin translation of the surname of the founder, August Horch. , meaning "listen", becomes in Latin. The four rings of the Audi logo each represent one of four car companies that banded together to create Audi's predecessor company, Auto Union. Audi's slogan is , meaning "Being Ahead through Technology". Audi, along with German brands BMW and Mercedes-Benz, is among the best-selling luxury automobile brands in the world. History Birth of the company and its name Automobile company Wanderer was originally established in 1885, later becoming a branch of Audi AG. Another company, NSU, which also later merged into Audi, was founded during this time, and later supplied the chassis for Gottlieb Daimler's four-wheeler. On 14 November 1899, August Horch (1868–1951) established the company A. Horch & Cie. in the Ehrenfeld district of Cologne. In 1902, he moved with his company to Reichenbach im Vogtland. On 10 May 1904, he founded the August Horch & Cie. Motorwagenwerke AG, a joint-stock company in Zwickau (State of Saxony). After troubles with Horch chief financial officer, August Horch left Motorwagenwerke and founded in Zwickau on 16 July 1909, his second company, the August Horch Automobilwerke GmbH. His former partners sued him for trademark infringement. The German Reichsgericht (Supreme Court) in Leipzig, eventually determined that the Horch brand belonged to his former company. Since August Horch was prohibited from using "Horch" as a trade name in his new car business, he called a meeting with close business friends, Paul and Franz Fikentscher from Zwickau. At the apartment of Franz Fikentscher, they discussed how to come up with a new name for the company. During this meeting, Franz's son was quietly studying Latin in a corner of the room. Several times he looked like he was on the verge of saying something but would just swallow his words and continue working, until he finally blurted out, "Father – audiatur et altera pars... wouldn't it be a good idea to call it audi instead of horch?" "Horch!" in German means "Hark!" or "hear", which is "Audi" in the singular imperative form of "audire" – "to listen" – in Latin. The idea was enthusiastically accepted by everyone attending the meeting. On 25 April 1910 the Audi Automobilwerke GmbH Zwickau (from 1915 on Audiwerke AG Zwickau) was entered in the company's register of Zwickau registration court. The first Audi automobile, the Audi Type A 10/ Sport-Phaeton, was produced in the same year, followed by the successor Type B 10/28PS in the same year. Audi started with a 2,612 cc inline-four engine model Type A, followed by a 3,564 cc model, as well as 4,680 cc and 5,720 cc models. These cars were successful even in sporting events. The first six-cylinder model Type M, 4,655 cc appeared in 1924. August Horch left the Audiwerke in 1920 for a high position at the ministry of transport, but he was still involved with Audi as a member of the board of trustees. In September 1921, Audi became the first German car manufacturer to present a production car, the Audi Type K, with left-handed drive. Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer when driving on the right. The merger of the four companies under the logo of four rings In August 1928, Jørgen Rasmussen, the owner of Dampf-Kraft-Wagen (DKW), acquired the majority of shares in Audiwerke AG. In the same year, Rasmussen bought the remains of the U.S. automobile manufacturer Rickenbacker, including the manufacturing equipment for 8-cylinder engines. These engines were used in Audi Zwickau and Audi Dresden models that were launched in 1929. At the same time, 6-cylinder and 4-cylinder (the "four" with a Peugeot engine) models were manufactured. Audi cars of that era were luxurious cars equipped with special bodywork. In 1932, Audi merged with Horch, DKW, and Wanderer, to form Auto Union AG, Chemnitz. It was during this period that the company offered the Audi Front that became the first European car to combine a six-cylinder engine with front-wheel drive. It used a power train shared with the Wanderer, but turned 180 degrees, so that the drive shaft faced the front. Before World War II, Auto Union used the four interlinked rings that make up the Audi badge today, representing these four brands. However, this badge was used only on Auto Union racing cars in that period while the member companies used their own names and emblems. The technological development became more and more concentrated and some Audi models were propelled by Horch- or Wanderer-built engines. Reflecting the economic pressures of the time, Auto Union concentrated increasingly on smaller cars through the 1930s, so that by 1938 the company's DKW brand accounted for 17.9% of the German car market, while Audi held only 0.1%. After the final few Audis were delivered in 1939 the "Audi" name disappeared completely from the new car market for more than two decades. Post-World War II Like most German manufacturing, at the onset of World War II the Auto Union plants were retooled for military production, and were a target for allied bombing during the war which left them damaged. Overrun by the Soviet Army in 1945, on the orders of the Soviet Union military administration the factories were dismantled as part of war reparations. Following this, the company's entire assets were expropriated without compensation. On 17 August 1948, Auto Union AG of Chemnitz was deleted from the commercial register. These actions had the effect of liquidating Germany's Auto Union AG. The remains of the Audi plant of Zwickau became the VEB (for "People Owned Enterprise") or AWZ (in English: Automobile Works Zwickau). With no prospect of continuing production in Soviet-controlled East Germany, Auto Union executives began the process of relocating what was left of the company to West Germany. A site was chosen in Ingolstadt, Bavaria, to start a spare parts operation in late 1945, which would eventually serve as the headquarters of the reformed Auto Union in 1949. The former Audi factory in Zwickau restarted assembly of the pre-war models in 1949. These DKW models were renamed to IFA F8 and IFA F9 and were similar to the West German versions. West and East German models were equipped with the traditional and renowned DKW two-stroke engines. The Zwickau plant manufactured the infamous Trabant until 1991, when it came under Volkswagen control—effectively bringing it under the same umbrella as Audi since 1945. New Auto Union unit A new West German headquartered Auto Union was launched in Ingolstadt with loans from the Bavarian state government and Marshall Plan aid. The reformed company was launched 3 September 1949 and continued DKW's tradition of producing front-wheel drive vehicles with two-stroke engines. This included production of a small but sturdy 125 cc motorcycle and a DKW delivery van, the DKW F89 L at Ingolstadt. The Ingolstadt site was large, consisting of an extensive complex of formerly military buildings which was suitable for administration as well as vehicle warehousing and distribution, but at this stage there was at Ingolstadt no dedicated plant suitable for mass production of automobiles: for manufacturing the company's first post-war mass-market passenger car plant capacity in Düsseldorf was rented from Rheinmetall-Borsig. It was only ten years later, after the company had attracted an investor, when funds became available for construction of major car plant at the Ingolstadt head office site. In 1958, in response to pressure from Friedrich Flick, then the company's largest single shareholder, Daimler-Benz took an 87% holding in the Auto Union company, and this was increased to a 100% holding in 1959. However, small two-stroke cars were not the focus of Daimler-Benz's interests, and while the early 1960s saw major investment in new Mercedes models and in a state of the art factory for Auto Union's, the company's aging model range at this time did not benefit from the economic boom of the early 1960s to the same extent as competitor manufacturers such as Volkswagen and Opel. The decision to dispose of the Auto Union business was based on its lack of profitability. Ironically, by the time they sold the business, it also included a large new factory and near production-ready modern four-stroke engine, which would enable the Auto Union business, under a new owner, to embark on a period of profitable growth, now producing not Auto Unions or DKWs, but using the "Audi" name, resurrected in 1965 after a 25-year gap. In 1964, Volkswagen acquired a 50% holding in the business, which included the new factory in Ingolstadt, the DKW and Audi brands along with the rights to the new engine design which had been funded by Daimler-Benz, who in return retained the dormant Horch trademark and the Düsseldorf factory which became a Mercedes-Benz van assembly plant. Eighteen months later, Volkswagen bought complete control of Ingolstadt, and by 1966 were using the spare capacity of the Ingolstadt plant to assemble an additional 60,000 Volkswagen Beetles per year. Two-stroke engines became less popular during the 1960s as customers were more attracted to the smoother four-stroke engines. In September 1965, the DKW F102 was fitted with a four-stroke engine and a facelift for the car's front and rear. Volkswagen dumped the DKW brand because of its associations with two-stroke technology, and having classified the model internally as the F103, sold it simply as the "Audi". Later developments of the model were named after their horsepower ratings and sold as the Audi 60, 75, 80, and Super 90, selling until 1972. Initially, Volkswagen was hostile to the idea of Auto Union as a standalone entity producing its own models having acquired the company merely to boost its own production capacity through the Ingolstadt assembly plant – to the point where Volkswagen executives ordered that the Auto Union name and flags bearing the four rings were removed from the factory buildings. Then VW chief Heinz Nordhoff explicitly forbade Auto Union from any further product development. Fearing that Volkswagen had no long-term ambition for the Audi brand, Auto Union engineers under the leadership of Ludwig Kraus developed the first Audi 100 in secret, without Nordhoff's knowledge. When presented with a finished prototype, Nordhoff was so impressed he authorised the car for production, which when launched in 1968, went on to be a huge success. With this, the resurrection of the Audi brand was now complete, this being followed by the first generation Audi 80 in 1972, which would in turn provide a template for VW's new front-wheel-drive water-cooled range which debuted from the mid-1970s onward. In 1969, Auto Union merged with NSU, based in Neckarsulm, near Stuttgart. In the 1950s, NSU had been the world's largest manufacturer of motorcycles, but had moved on to produce small cars like the NSU Prinz, the TT and TTS versions of which are still popular as vintage race cars. NSU then focused on new rotary engines based on the ideas of Felix Wankel. In 1967, the new NSU Ro 80 was a car well ahead of its time in technical details such as aerodynamics, light weight, and safety. However, teething problems with the rotary engines put an end to the independence of NSU. The Neckarsulm plant is now used to produce the larger Audi models A6 and A8. The Neckarsulm factory is also home of the "quattro GmbH" (from November 2016 "Audi Sport GmbH"), a subsidiary responsible for development and production of Audi high-performance models: the R8 and the RS model range. Modern era The new merged company was incorporated on 1 January 1969 and was known as Audi NSU Auto Union AG, with its headquarters at NSU's Neckarsulm plant, and saw the emergence of Audi as a separate brand for the first time since the pre-war era. Volkswagen introduced the Audi brand to the United States for the 1970 model year. That same year, the mid-sized car that NSU had been working on, the K70, originally intended to slot between the rear-engined Prinz models and the futuristic NSU Ro 80, was instead launched as a Volkswagen. After the launch of the Audi 100 of 1968, the Audi 80/Fox (which formed the basis for the 1973 Volkswagen Passat) followed in 1972 and the Audi 50 (later rebadged as the Volkswagen Polo) in 1974. The Audi 50 was a seminal design because it was the first incarnation of the Golf/Polo concept, one that led to a hugely successful world car. Ultimately, the Audi 80 and 100 (progenitors of the A4 and A6, respectively) became the company's biggest sellers, whilst little investment was made in the fading NSU range; the Prinz models were dropped in 1973 whilst the fatally flawed NSU Ro80 went out of production in 1977, spelling the effective end of the NSU brand. Production of the Audi 100 had been steadily moved from Ingolstadt to Neckarsulm as the 1970s had progressed, and by the appearance of the second generation C2 version in 1976, all production was now at the former NSU plant. Neckarsulm from that point onward would produce Audi's higher-end models. The Audi image at this time was a conservative one, and so, a proposal from chassis engineer Jörg Bensinger was accepted to develop the four-wheel drive technology in Volkswagen's Iltis military vehicle for an Audi performance car and rally racing car. The performance car, introduced in 1980, was named the "Audi Quattro", a turbocharged coupé which was also the first German large-scale production vehicle to feature permanent all-wheel drive through a centre differential. Commonly referred to as the "Ur-Quattro" (the "Ur-" prefix is a German augmentative used, in this case, to mean "original" and is also applied to the first generation of Audi's S4 and S6 Sport Saloons, as in "UrS4" and "UrS6"), few of these vehicles were produced (all hand-built by a single team), but the model was a great success in rallying. Prominent wins proved the viability of all-wheel-drive racecars, and the Audi name became associated with advances in automotive technology. In 1985, with the Auto Union and NSU brands effectively dead, the company's official name was now shortened to simply Audi AG. At the same time the company's headquarters moved back to Ingolstadt and two new wholly owned subsidiaries; Auto Union GmbH and NSU GmbH, were formed to own and manage the historical trademarks and intellectual property of the original constituent companies (the exception being Horch, which had been retained by Daimler-Benz after the VW takeover), and to operate Audi's heritage operations. In 1986, as the Passat-based Audi 80 was beginning to develop a kind of "grandfather's car" image, the type 89 was introduced. This completely new development sold extremely well. However, its modern and dynamic exterior belied the low performance of its base engine, and its base package was quite spartan (even the passenger-side mirror was an option.) In 1987, Audi put forward a new and very elegant Audi 90, which had a much superior set of standard features. In the early 1990s, sales began to slump for the Audi 80 series, and some basic construction problems started to surface. In the early part of the 21st century, Audi set forth on a German racetrack to claim and maintain several world records, such as top speed endurance. This effort was in-line with the company's heritage from the 1930s racing era Silver Arrows. Through the early 1990s, Audi began to shift its target market upscale to compete against German automakers Mercedes-Benz and BMW. This began with the release of the Audi V8 in 1990. It was essentially a new engine fitted to the Audi 100/200, but with noticeable bodywork differences. Most obvious was the new grille that was now incorporated in the bonnet. By 1991, Audi had the four-cylinder Audi 80, the 5-cylinder Audi 90 and Audi 100, the turbocharged Audi 200 and the Audi V8. There was also a coupé version of the 80/90 with both four- and five-cylinder engines. Although the five-cylinder engine was a successful and robust powerplant, it was still a little too different for the target market. With the introduction of an all-new Audi 100 in 1992, Audi introduced a 2.8L V6 engine. This engine was also fitted to a face-lifted Audi 80 (all 80 and 90 models were now badged 80 except for the USA), giving this model a choice of four-, five-, and six-cylinder engines, in saloon, coupé and convertible body styles. The five-cylinder was soon dropped as a major engine choice; however, a turbocharged version remained. The engine, initially fitted to the 200 quattro 20V of 1991, was a derivative of the engine fitted to the Sport Quattro. It was fitted to the Audi Coupé, named the S2, and also to the Audi 100 body, and named the S4. These two models were the beginning of the mass-produced S series of performance cars. Audi 5000 unintended acceleration allegations Sales in the United States fell after a series of recalls from 1982 to 1987 of Audi 5000 models associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents. At the time, NHTSA was investigating 50 car models from 20 manufacturers for sudden surges of power. A 60 Minutes report aired 23 November 1986, featuring interviews with six people who had sued Audi after reporting unintended acceleration, showing an Audi 5000 ostensibly suffering a problem when the brake pedal was pushed. Subsequent investigation revealed that 60 Minutes had engineered the failure – fitting a canister of compressed air on the passenger-side floor, linked via a hose to a hole drilled into the transmission. Audi contended, prior to findings by outside investigators, that the problems were caused by driver error, specifically pedal misapplication. Subsequently, the National Highway Traffic Safety Administration (NHTSA) concluded that the majority of unintended acceleration cases, including all the ones that prompted the 60 Minutes report, were caused by driver error such as confusion of pedals. CBS did not acknowledge the test results of involved government agencies, but did acknowledge the similar results of another study. In a review study published in 2012, NHTSA summarized its past findings about the Audi unintended acceleration problems: "Once an unintended acceleration had begun, in the Audi 5000, due to a failure in the idle-stabilizer system (producing an initial acceleration of 0.3g), pedal misapplication resulting from panic, confusion, or unfamiliarity with the Audi 5000 contributed to the severity of the incident." This summary is consistent with the conclusions of NHTSA's most technical analysis at the time: "Audi idle-stabilization systems were prone to defects which resulted in excessive idle speeds and brief unanticipated accelerations of up to 0.3g [which is similar in magnitude to an emergency stop in a subway car]. These accelerations could not be the sole cause of [(long-duration) sudden acceleration incidents (SAI)], but might have triggered some SAIs by startling the driver. The defective idle-stabilization system performed a type of electronic throttle control. Significantly: multiple "intermittent malfunctions of the electronic control unit were observed and recorded ... and [were also observed and] reported by Transport Canada." With a series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models. Later repairs, of 250,000 cars dating back to 1978, added a device requiring the driver to press the brake pedal before shifting out of park. A legacy of the Audi 5000 and other reported cases of sudden unintended acceleration are intricate gear stick patterns and brake interlock mechanisms to prevent inadvertent shifting into forward or reverse. It is unclear how the defects in the idle-stabilization system were addressed. Audi's U.S. sales, which had reached 74,061 in 1985, dropped to 12,283 in 1991 and remained level for three years, – with resale values falling dramatically. Audi subsequently offered increased warranty protection and renamed the affected models – with the 5000 becoming the 100 and 200 in 1989 – and reached the same sales levels again only by model year 2000. A 2010 BusinessWeek article – outlining possible parallels between Audi's experience and 2009–2010 Toyota vehicle recalls – noted a class-action lawsuit filed in 1987 by about 7,500 Audi 5000-model owners remains unsettled and remains contested in Chicago's Cook County after appeals at the Illinois state and U.S. federal levels. Model introductions In the mid-to-late 1990s, Audi introduced new technologies including the use of aluminium construction. Produced from 1999 to 2005, the Audi A2 was a futuristic super mini, born from the Al2 concept, with many features that helped regain consumer confidence, like the aluminium space frame, which was a first in production car design. In the A2 Audi further expanded their TDI technology through the use of frugal three-cylinder engines. The A2 was extremely aerodynamic and was designed around a wind tunnel. The Audi A2 was criticised for its high price and was never really a sales success but it planted Audi as a cutting-edge manufacturer. The model, a Mercedes-Benz A-Class competitor, sold relatively well in Europe. However, the A2 was discontinued in 2005 and Audi decided not to develop an immediate replacement. The next major model change came in 1995 when the Audi A4 replaced the Audi 80. The new nomenclature scheme was applied to the Audi 100 to become the Audi A6 (with a minor facelift). This also meant the S4 became the S6 and a new S4 was introduced in the A4 body. The S2 was discontinued. The Audi Cabriolet continued on (based on the Audi 80 platform) until 1999, gaining the engine upgrades along the way. A new A3 hatchback model (sharing the Volkswagen Golf Mk4's platform) was introduced to the range in 1996, and the radical Audi TT coupé and roadster were debuted in 1998 based on the same underpinnings. The engines available throughout the range were now a 1.4 L, 1.6 L and 1.8 L four-cylinder, 1.8 L four-cylinder turbo, 2.6 L and 2.8 L V6, 2.2 L turbo-charged five-cylinder and the 4.2 L V8 engine. The V6s were replaced by new 2.4 L and 2.8 L 30V V6s in 1998, with marked improvement in power, torque and smoothness. Further engines were added along the way, including a 3.7 L V8 and 6.0 L W12 engine for the A8. Audi AG today Audi's sales grew strongly in the 2000s, with deliveries to customers increasing from 653,000 in 2000 to 1,003,000 in 2008. The largest sales increases came from Eastern Europe (+19.3%), Africa (+17.2%) and the Middle East (+58.5%). China in particular has become a key market, representing 108,000 out of 705,000 cars delivered in the first three quarters of 2009. One factor for its popularity in China is that Audis have become the car of choice for purchase by the Chinese government for officials, and purchases by the government are responsible for 20% of its sales in China. As of late 2009, Audi's operating profit of €1.17 billion ($1.85 billion) made it the biggest contributor to parent Volkswagen Group's nine-month operating profit of €1.5 billion, while the other marques in Group such as Bentley and SEAT had suffered considerable losses. May 2011 saw record sales for Audi of America with the new Audi A7 and Audi A3 TDI Clean Diesel. In May 2012, Audi reported a 10% increase in its sales—from 408 units to 480 in the last year alone. Audi manufactures vehicles in seven plants around the world, some of which are shared with other VW Group marques although many sub-assemblies such as engines and transmissions are manufactured within other Volkswagen Group plants. Audi's two principal assembly plants in Germany are: Ingolstadt, the former Auto Union site originally opened in 1945 and substantially rebuilt by Daimler-Benz in 1962, and acquired by Volkswagen in 1964 (Q2, A3, A4, A5) Neckarsulm, the former NSU plant, acquired by Volkswagen in 1969: (A4, A5 (cabrio), A6, A7, A8, R8, and all RS variants) - a satellite plant at nearby Böllinger Höfe produces the e-tron GT Outside of Germany, Audi produces vehicles at: Aurangabad, India, since 2006 Bratislava, Slovakia, shared with Volkswagen, SEAT, Škoda and Porsche (Q7 and Q8) Brussels, Belgium, acquired from Volkswagen in 2007 (e-tron) Changchun, China, since 1995 Győr, Hungary (TT, A3, Q3) Jakarta, Indonesia, since 2011 Martorell, Spain, shared with SEAT and Volkswagen (A1, Q3) San José Chiapa, Mexico (2nd gen Q5) In September 2012, Audi announced the construction of its first North American manufacturing plant in Puebla, Mexico. This plant became operative in 2016 and produces the second generation Q5. From 2002 up to 2003, Audi headed the Audi Brand Group, a subdivision of the Volkswagen Group's Automotive Division consisting of Audi, Lamborghini and SEAT, which was focused on sporty values, with the marques' product vehicles and performance being under the higher responsibility of the Audi brand. In January 2014, Audi, along with the Wireless Power Consortium, operated a booth which demonstrated a phone compartment using the Qi open interface standard at the Consumer Electronics Show (CES). In May, most of the Audi dealers in the UK falsely claimed that the Audi A7, A8, and R8 were Euro NCAP safety tested, all achieving five out of five stars. In fact none were tested. In 2015, Audi admitted that at least 2.1 million Audi cars had been involved in the Volkswagen emissions testing scandal in which software installed in the cars manipulated emissions data to fool regulators and allow the cars to pollute at higher than government-mandated levels. The A1, A3, A4, A5, A6, TT, Q3 and Q5 models were implicated in the scandal. Audi promised to quickly find a technical solution and upgrade the cars so they can function within emissions regulations. Ulrich Hackenberg, the head of research and development at Audi, was suspended in relation to the scandal. Despite widespread media coverage about the scandal through the month of September, Audi reported that U.S. sales for the month had increased by 16.2%. Audi's parent company Volkswagen announced on 18 June 2018 that Audi chief executive Rupert Stadler had been arrested. In November 2015, the U.S. Environmental Protection Agency implicated the 3-liter diesel engine versions of the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and the Q5 as further models that had emissions regulation defeat-device software installed. Thus, these models emitted nitrogen oxide at up to nine times the legal limit when the car detected that it was not hooked up to emissions testing equipment. In November 2016, Audi expressed an intention to establish an assembly factory in Pakistan, with the company's local partner acquiring land for a plant in Korangi Creek Industrial Park in Karachi. Approval of the plan would lead to an investment of $30 million in the new plant. Audi planned to cut 9,500 jobs in Germany starting from 2020 till 2025 to fund electric vehicles and digital working. In February 2020, Volkswagen AG announced that it plans to take over all Audi shares it does not own (totalling 0.36%) via a squeeze-out according to German stock corporation law, thus making Audi a fully owned subsidiary of the Volkswagen Group. This change took effect from 16 November 2020, when Audi became a wholly owned subsidiary of the Volkswagen Group. In January 2021, Audi announced that it is planning to sell 1 million vehicles in China in 2023, comparing to 726,000 vehicles in 2020. Technology Audi AI Audi AI is a driver assist feature offered by Audi. The company's stated intent is to offer fully autonomous driving at a future time, acknowledging that legal, regulatory and technical hurdles must be overcome to achieve this goal. On 4 June 2017, Audi stated that its new A8 will be fully self-driving for speeds up to 60 km/h using its Audi AI. Contrary to other cars, the driver will not have to do safety checks such as touching the steering wheel every 15 seconds to use this feature. The Audi A8 will therefore be the first production car to reach level 3 autonomous driving, meaning that the driver can safely turn their attention away from driving tasks, e.g. the driver can text or watch a movie. Audi will also be the first manufacturer to use a 3D Lidar system in addition to cameras and ultrasonic sensors for their AI. Bodyshells Audi produces 100% galvanised cars to prevent corrosion, and was the first mass-market vehicle to do so, following introduction of the process by Porsche, c. 1975. Along with other precautionary measures, the full-body zinc coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year warranty against corrosion perforation to currently 12 years (except for aluminium bodies which do not rust). Space Frame Audi introduced a new series of vehicles in the mid-1990s and continues to pursue new technology and high performance. An all-aluminium car was brought forward by Audi, and in 1994 the Audi A8 was launched, which introduced aluminium space frame technology (called Audi Space Frame or ASF) which saves weight and improves torsion rigidity compared to a conventional steel frame. Prior to that effort, Audi used examples of the Type 44 chassis fabricated out of aluminium as test-beds for the technique. The disadvantage of the aluminium frame is that it is very expensive to repair and requires a specialized aluminium bodyshop. The weight reduction is somewhat offset by the quattro four-wheel drive system which is standard in most markets. Nonetheless, the A8 is usually the lightest all-wheel drive car in the full-size luxury segment, also having best-in-class fuel economy. The Audi A2, Audi TT and Audi R8 also use Audi Space Frame designs. Drivetrains Layout For most of its lineup (excluding the A3, A1, and TT models), Audi has not adopted the transverse engine layout which is typically found in economy cars (such as Peugeot and Citroën), since that would limit the type and power of engines that can be installed. To be able to mount powerful engines (such as a V8 engine in the Audi S4 and Audi RS4, as well as the W12 engine in the Audi A8L W12), Audi has usually engineered its more expensive cars with a longitudinally front-mounted engine, in an "overhung" position, over the front wheels in front of the axle line - this layout dates back to the DKW and Auto Union saloons from the 1950s. But while this allows for the easy adoption of all-wheel drive, it goes against the ideal 50:50 weight distribution. In all its post Volkswagen-era models, Audi has firmly refused to adopt the traditional rear-wheel drive layout favored by its two archrivals Mercedes-Benz and BMW, favoring either front-wheel drive or all-wheel drive. The majority of Audi's lineup in the United States features all-wheel drive standard on most of its expensive vehicles (only the entry-level trims of the A4 and A6 are available with front-wheel drive), in contrast to Mercedes-Benz and BMW whose lineup treats all-wheel drive as an option. BMW did not offer all-wheel drive on its V8-powered cars (as opposed to crossover SUVs) until the 2010 BMW 7 Series and 2011 BMW 5 Series, while the Audi A8 has had all-wheel drive available/standard since the 1990s. Regarding high-performance variants, Audi S and RS models have always had all-wheel drive, unlike their direct rivals from BMW M and Mercedes-AMG whose cars are rear-wheel drive only (although their performance crossover SUVs are all-wheel drive). Audi has recently applied the quattro badge to models such as the A3 and TT which do not use the Torsen-based system as in prior years with a mechanical center differential, but with the Haldex Traction electro-mechanical clutch AWD system. Engines Prior to the introduction of the Audi 80 and Audi 50 in 1972 and 1974, respectively, Audi had led the development of the EA111 and EA827 inline-four engine families. These new power units underpinned the water-cooled revival of parent company Volkswagen (in the Polo, Golf, Passat and Scirocco), whilst the many derivatives and descendants of these two basic engine designs have appeared in every generation of VW Group vehicles right up to the present day. In the 1980s, Audi, along with Volvo, was the champion of the inline-five cylinder, 2.1/2.2 L engine as a longer-lasting alternative to more traditional six-cylinder engines. This engine was used not only in production cars but also in their race cars. The 2.1 L inline five-cylinder engine was used as a base for the rally cars in the 1980s, providing well over after modification. Before 1990, there were engines produced with a displacement between 2.0 L and 2.3 L. This range of engine capacity allowed for both fuel economy and power. For the ultra-luxury version of its Audi A8 fullsize luxury flagship sedan, the Audi A8L W12, Audi uses the Volkswagen Group W12 engine instead of the conventional V12 engine favored by rivals Mercedes-Benz and BMW. The W12 engine configuration (also known as a "WR12") is created by forming two imaginary narrow-angle 15° VR6 engines at an angle of 72°, and the narrow angle of each set of cylinders allows just two overhead camshafts to drive each pair of banks, so just four are needed in total. The advantage of the W12 engine is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 engine could have only a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, the 6.0 L W12 in the Audi A8L W12 is smaller in overall dimensions than the 4.2 L V8 that powers the Audi A8 4.2 variants. The 2011 Audi A8 debuted a revised 6.3-litre version of the W12 (WR12) engine with . Fuel Stratified Injection New models of the A3, A4, A6 and A8 have been introduced, with the ageing 1.8-litre engine now having been replaced by new Fuel Stratified Injection (FSI) engines. Nearly every petroleum burning model in the range now incorporates this fuel-saving technology. Direct-Shift Gearbox In 2003, Volkswagen introduced the Direct-Shift Gearbox (DSG), a type of dual-clutch transmission. It is a type of automatic transmission, drivable like a conventional torque converter automatic transmission. Based on the gearbox found in the Group B S1, the system includes dual electro-hydraulically controlled clutches instead of a torque converter. This is implemented in some VW Golfs, Audi A3, Audi A4 and TT models where DSG is called S-Tronic. LED daytime running lights Beginning in 2005, Audi has implemented white LED technology as daytime running lights (DRL) in their products. The distinctive shape of the DRLs has become a trademark of sorts. LEDs were first introduced on the Audi A8 W12, the world's first production car to have LED DRLs, and have since spread throughout the entire model range. The LEDs are present on some Audi billboards. Since 2010, Audi has also offered the LED technology in low- and high-beam headlights. Multi Media Interface Starting with the 2003 Audi A8, Audi has used a centralised control interface for its on-board infotainment systems, called Multi Media Interface (MMI). It is essentially a rotating control knob and 'segment' buttons – designed to control all in-car entertainment devices (radio, CD changer, iPod, TV tuner), satellite navigation, heating and ventilation, and other car controls with a screen. The availability of MMI has gradually filtered down the Audi lineup, and following its introduction on the third generation A3 in 2011, MMI is now available across the entire range. It has been generally well received, as it requires less menu-surfing with its segment buttons around a central knob, along with 'main function' direct access buttons – with shortcuts to the radio or phone functions. The colour screen is mounted on the upright dashboard, and on the A4 (new), A5, A6, A8, and Q7, the controls are mounted horizontally. Synthetic fuels Audi has assisted with technology to produce synthetic diesel from water and carbon dioxide. Audi calls the synthetic diesel E-diesel. It is also working on synthetic gasoline (which it calls E-gasoline). Logistics Audi uses scanning gloves for parts registration during assembly, and automatic robots to transfer cars from factory to rail cars. Models Current model range The following tables list Audi production vehicles that are sold as of 2018: S and RS models Electric vehicles Audi is planning an alliance with the Japanese electronics giant Sanyo to develop a pilot hybrid electric project for the Volkswagen Group. The alliance could result in Sanyo batteries and other electronic components being used in future models of the Volkswagen Group. Concept electric vehicles unveiled to date include the Audi A1 Sportback Concept, Audi A4 TDI Concept E, and the fully electric Audi e-tron Concept Supercar. Self-driving cars In December 2018, Audi announced to invest 14 billion Euro ($15.9 billion) in e-mobility, self-driving cars. Production figures Data from 1998 to 2010. Figures for different body types/versions of models have been merged to create overall figures for each model. Motorsport Audi has competed in various forms of motorsports. Audi's tradition in motorsport began with their former company Auto Union in the 1930s. In the 1990s, Audi found success in the Touring and Super Touring categories of motor racing after success in circuit racing in North America. Rallying In 1980, Audi released the Quattro, a four-wheel drive (4WD) turbocharged car that went on to win rallies and races worldwide. It is considered one of the most significant rally cars of all time, because it was one of the first to take advantage of the then-recently changed rules which allowed the use of four-wheel drive in competition racing. Many critics doubted the viability of four-wheel drive racers, thinking them to be too heavy and complex, yet the Quattro was to become a successful car. It led its first rally before going off the road, however, the rally world had been served notice 4WD was the future. The Quattro went on to achieve much success in the World Rally Championship. It won the 1983 (Hannu Mikkola) and the 1984 (Stig Blomqvist) drivers' titles, and brought Audi the manufacturers' title in 1982 and 1984. In 1984, Audi launched the short-wheelbase Sport Quattro which dominated rally races in Monte Carlo and Sweden, with Audi taking all podium places, but succumbed to problems further into WRC contention. In 1985, after another season mired in mediocre finishes, Walter Röhrl finished the season in his Sport Quattro S1, and helped place Audi second in the manufacturers' points. Audi also received rally honours in the Hong Kong to Beijing rally in that same year. Michèle Mouton, the only female driver to win a round of the World Rally Championship and a driver for Audi, took the Sport Quattro S1, now simply called the "S1", and raced in the Pikes Peak International Hill Climb. The climb race pits a driver and car to drive to the summit of the Pikes Peak mountain in Colorado, and in 1985, Michèle Mouton set a new record of 11:25.39, and being the first woman to set a Pikes Peak record. In 1986, Audi formally left international rally racing following an accident in Portugal involving driver Joaquim Santos in his Ford RS200. Santos swerved to avoid hitting spectators in the road, and left the track into the crowd of spectators on the side, killing three and injuring 30. Bobby Unser used an Audi in that same year to claim a new record for the Pikes Peak Hill Climb at 11:09.22. In 1987, Walter Röhrl claimed the title for Audi setting a new Pikes Peak International Hill Climb record of 10:47.85 in his Audi S1, which he had retired from the WRC two years earlier. The Audi S1 employed Audi's time-tested inline-five-cylinder turbocharged engine, with the final version generating . The engine was mated to a six-speed gearbox and ran on Audi's famous four-wheel drive system. All of Audi's top drivers drove this car; Hannu Mikkola, Stig Blomqvist, Walter Röhrl and Michèle Mouton. This Audi S1 started the range of Audi 'S' cars, which now represents an increased level of sports-performance equipment within the mainstream Audi model range. In the United States As Audi moved away from rallying and into circuit racing, they chose to move first into America with the Trans-Am in 1988. In 1989, Audi moved to International Motor Sports Association (IMSA) GTO with the Audi 90, however as they avoided the two major endurance events (Daytona and Sebring) despite winning on a regular basis, they would lose out on the title. Touring cars In 1990, having completed their objective to market cars in North America, Audi returned to Europe, turning first to the Deutsche Tourenwagen Meisterschaft (DTM) series with the Audi V8, and then in 1993, being unwilling to build cars for the new formula, they turned their attention to the fast-growing Super Touring series, which are a series of national championships. Audi first entered in the French Supertourisme and Italian Superturismo. In the following year, Audi would switch to the German Super Tourenwagen Cup (known as STW), and then to British Touring Car Championship (BTCC) the year after that. The Fédération Internationale de l'Automobile (FIA), having difficulty regulating the quattro four-wheel drive system, and the impact it had on the competitors, would eventually ban all four-wheel drive cars from competing in the series in 1998, but by then, Audi switched all their works efforts to sports car racing. By 2000, Audi would still compete in the US with their RS4 for the SCCA Speed World GT Challenge, through dealer/team Champion Racing competing against Corvettes, Vipers, and smaller BMWs (where it is one of the few series to permit 4WD cars). In 2003, Champion Racing entered an RS6. Once again, the quattro four-wheel drive was superior, and Champion Audi won the championship. They returned in 2004 to defend their title, but a newcomer, Cadillac with the new Omega Chassis CTS-V, gave them a run for their money. After four victories in a row, the Audis were sanctioned with several negative changes that deeply affected the car's performance. Namely, added ballast weights, and Champion Audi deciding to go with different tyres, and reducing the boost pressure of the turbocharger. In 2004, after years of competing with the TT-R in the revitalised DTM series, with privateer team Abt Racing/Christian Abt taking the 2002 title with Laurent Aïello, Audi returned as a full factory effort to touring car racing by entering two factory-supported Joest Racing A4 DTM cars. 24 Hours of Le Mans Audi began racing prototype sportscars in 1999, debuting at the Le Mans 24 hour. Two car concepts were developed and raced in their first season - the Audi R8R (open-cockpit 'roadster' prototype) and the Audi R8C (closed-cockpit 'coupé' GT-prototype). The R8R scored a credible podium on its racing debut at Le Mans and was the concept which Audi continued to develop into the 2000 season due to favourable rules for open-cockpit prototypes. However, most of the competitors (such as BMW, Toyota, Mercedes and Nissan) retired at the end of 1999. The factory-supported Joest Racing team won at Le Mans three times in a row with the Audi R8 (2000–2002), as well as winning every race in the American Le Mans Series in its first year. Audi also sold the car to customer teams such as Champion Racing. In 2003, two Bentley Speed 8s, with engines designed by Audi, and driven by Joest drivers loaned to the fellow Volkswagen Group company, competed in the GTP class, and finished the race in the top two positions, while the Champion Racing R8 finished third overall, and first in the LMP900 class. Audi returned to the winner's podium at the 2004 race, with the top three finishers all driving R8s: Audi Sport Japan Team Goh finished first, Audi Sport UK Veloqx second, and Champion Racing third. At the 2005 24 Hours of Le Mans, Champion Racing entered two R8s, along with an R8 from the Audi PlayStation Team Oreca. The R8s (which were built to old LMP900 regulations) received a narrower air inlet restrictor, reducing power, and an additional of weight compared to the newer LMP1 chassis. On average, the R8s were about 2–3 seconds off pace compared to the Pescarolo–Judd. But with a team of excellent drivers and experience, both Champion R8s were able to take first and third, while the Oreca team took fourth. The Champion team was also the first American team to win Le Mans since the Gulf Ford GTs in 1967. This also ends the long era of the R8; however, its replacement for 2006, called the Audi R10 TDI, was unveiled on 13 December 2005. The R10 TDI employed many new and innovative features, the most notable being the twin-turbocharged direct injection diesel engine. It was first raced in the 2006 12 Hours of Sebring as a race-test in preparation for the 2006 24 Hours of Le Mans, which it later went on to win. Audi had a win in the first diesel sports car at 12 Hours of Sebring (the car was developed with a Diesel engine due to ACO regulations that favor diesel engines). As well as winning the 24 Hours of Le Mans in 2006, the R10 TDI beat the Peugeot 908 HDi FAP in , and in , (however Peugeot won the 24h in 2009) with a podium clean-sweep (all four 908 entries retired) while breaking a distance record (set by the Porsche 917K of Martini Racing in ), in with the R15 TDI Plus. Audi's sports car racing success would continue with the Audi R18's victory at the 2011 24 Hours of Le Mans. Audi Sport Team Joest's Benoît Tréluyer earned Audi their first pole position in five years while the team's sister car locked out the front row. Early accidents eliminated two of Audi's three entries, but the sole remaining Audi R18 TDI of Tréluyer, Marcel Fässler, and André Lotterer held off the trio of Peugeot 908s to claim victory by a margin of 13.8 seconds. Results American Le Mans Series Audi entered a factory racing team run by Joest Racing into the American Le Mans Series under the Audi Sport North America name in 2000. This was a successful operation with the team winning on its debut in the series at the 2000 12 Hours of Sebring. Factory-backed Audi R8s were the dominant car in ALMS taking 25 victories between 2000 and the end of the 2002 season. In 2003, Audi sold customer cars to Champion Racing as well as continuing to race the factory Audi Sport North America team. Champion Racing won many races as a private team running Audi R8s and eventually replaced Team Joest as the Audi Sport North America between 2006 and 2008. Since 2009 Audi has not taken part in full American Le Mans Series Championships, but has competed in the series opening races at Sebring, using the 12-hour race as a test for Le Mans, and also as part of the 2012 FIA World Endurance Championship season calendar. Results European Le Mans Series Audi participated in the 2003 1000km of Le Mans which was a one-off sports car race in preparation for the 2004 European Le Mans Series. The factory team Audi Sport UK won races and the championship in the 2004 season but Audi was unable to match their sweeping success of Audi Sport North America in the American Le Mans Series, partly due to the arrival of a factory competitor in LMP1, Peugeot. The French manufacturer's 908 HDi FAP became the car to beat in the series from 2008 onwards with 20 LMP wins. However, Audi were able to secure the championship in 2008 even though Peugeot scored more race victories in the season. Results World Endurance Championship 2012 In 2012, the FIA sanctioned a World Endurance Championship which would be organised by the ACO as a continuation of the ILMC. Audi competed won the first WEC race at Sebring and followed this up with a further three successive wins, including the 2012 24 Hours of Le Mans. Audi scored a final 5th victory in the 2012 WEC in Bahrain and were able to win the inaugural WEC Manufacturers' Championship. 2013 As defending champions, Audi once again entered the Audi R18 e-tron quattro chassis into the 2013 WEC and the team won the first five consecutive races, including the 2013 24 Hours of Le Mans. The victory at Round 5, Circuit of the Americas, was of particular significance as it marked the 100th win for Audi in Le Mans prototypes. Audi secured their second consecutive WEC Manufacturers' Championship at Round 6 after taking second place and half points in the red-flagged Fuji race. 2014 For the 2014 season, Audi entered a redesigned and upgraded R18 e-tron quattro which featured a 2 MJ energy recovery system. As defending champions, Audi would once again face a challenge in LMP1 from Toyota, and additionally from Porsche who returned to endurance racing after a 16-year absence. The season-opening 6hrs of Silverstone was a disaster for Audi who saw both cars retire from the race, marking the first time that an Audi car has failed to score a podium in a World Endurance Championship race. Results Formula E Audi provide factory support to Abt Sportsline in the FIA Formula E Championship, The team competed under the title of Audi Sport Abt Formula E Team in the inaugural 2014-15 Formula E season. On 13 February 2014 the team announced its driver line up as Daniel Abt and World Endurance Championship driver Lucas di Grassi. Formula One Audi has been linked to Formula One in recent years but has always resisted due to the company's opinion that it is not relevant to road cars, but hybrid power unit technology has been adopted into the sport, swaying the company's view and encouraging research into the program by former Ferrari team principal Stefano Domenicali. Audi announced in August 2022 that it would enter the Championship as an engine manufacturer in . In October, Audi confirmed its partnership with Sauber Motorsport for the year 2026, acquiring a stake in the company for the German brand to enter the competition by renaming the team and supplying engines. Current factory drivers Marketing Branding The Audi emblem is four overlapping rings that represent the four marques of Auto Union. The Audi emblem symbolises the amalgamation of Audi with DKW, Horch and Wanderer: the first ring from the left represents Audi, the second represents DKW, third is Horch, and the fourth and last ring Wanderer. The design is popularly believed to have been the idea of Klaus von Oertzen, the director of sales at Wanderer – when Berlin was chosen as the host city for the 1936 Summer Olympics and that a form of the Olympic logo symbolized the newly established Auto Union's desire to succeed. Somewhat ironically, the International Olympic Committee later sued Audi in the International Trademark Court in 1995, where they lost. The original "Audi" script, with the distinctive slanted tails on the "A" and "d" was created for the historic Audi company in 1920 by the famous graphic designer Lucian Bernhard, and was resurrected when Volkswagen revived the brand in 1965. Following the demise of NSU in 1977, less prominence was given to the four rings, in preference to the "Audi" script encased within a black (later red) ellipse, and was commonly displayed next to the Volkswagen roundel when the two brands shared a dealer network under the V.A.G banner. The ellipse (known as the Audi Oval) was phased out after 1994, when Audi formed its own independent dealer network, and prominence was given back to the four rings – at the same time Audi Sans (a derivative of Univers) was adopted as the font for all marketing materials, corporate communications and was also used in the vehicles themselves. As part of Audi's centennial celebration in 2009, the company updated the logo, changing the font to left-aligned Audi Type, and altering the shading for the overlapping rings. The revised logo was designed by Rayan Abdullah. Audi developed a Corporate Sound concept, with Audi Sound Studio designed for producing the Corporate Sound. The Corporate Sound project began with sound agency Klangerfinder GmbH & Co KG and s12 GmbH. Audio samples were created in Klangerfinder's sound studio in Stuttgart, becoming part of Audi Sound Studio collection. Other Audi Sound Studio components include The Brand Music Pool, The Brand Voice. Audi also developed Sound Branding Toolkit including certain instruments, sound themes, rhythm and car sounds which all are supposed to reflect the AUDI sound character. Audi started using a beating heart sound trademark beginning in 1996. An updated heartbeat sound logo, developed by agencies KLANGERFINDER GmbH & Co KG of Stuttgart and S12 GmbH of Munich, was first used in 2010 in an Audi A8 commercial with the slogan The Art of Progress. Slogans Audi's corporate tagline is , meaning "Progress through Technology". The German-language tagline is used in many European countries, including the United Kingdom (but not in Italy, where is used), and in other markets, such as Latin America, Oceania, Africa and parts of Asia including Japan. Originally, the American tagline was Innovation through technology, but in Canada Vorsprung durch Technik was used. Since 2007, Audi has used the slogan Truth in Engineering in the U.S. However, since the Audi emissions testing scandal came to light in September 2015, this slogan was lambasted for being discordant with reality. In fact, just hours after disgraced Volkswagen CEO Martin Winterkorn admitted to cheating on emissions data, an advertisement during the 2015 Primetime Emmy Awards promoted Audi's latest advances in low emissions technology with Kermit the Frog stating, "It's not that easy being green." Vorsprung durch Technik was first used in English-language advertising after Sir John Hegarty of the Bartle Bogle Hegarty advertising agency visited the Audi factory in 1982. In the original British television commercials, the phrase was voiced by Geoffrey Palmer. After its repeated use in advertising campaigns, the phrase found its way into popular culture, including the British comedy Only Fools and Horses, the U2 song "Zooropa" and the Blur song "Parklife". Similar-sounding phrases have also been used, including as the punchline for a joke in the movie Lock, Stock, and Two Smoking Barrels and in the British TV series Peep Show. Typography Audi Sans (based on Univers Extended) was originally created in 1997 by Ole Schäfer for MetaDesign. MetaDesign was later commissioned for a new corporate typeface called Audi Type, designed by Paul van der Laan and Pieter van Rosmalen of Bold Monday. The font began to appear in Audi's 2009 products and marketing materials. Sponsorships Audi is a strong partner of different kinds of sports. In football, long partnerships exist between Audi and domestic clubs including Bayern Munich, Hamburger SV, 1. FC Nürnberg, Hertha BSC, and Borussia Mönchengladbach and international clubs including Chelsea, Real Madrid, FC Barcelona, A.C. Milan, AFC Ajax and Perspolis. Audi also sponsors winter sports: The Audi FIS Alpine Ski World Cup is named after the company. Additionally, Audi supports the German Ski Association (DSV) as well as the alpine skiing national teams of Switzerland, Sweden, Finland, France, Liechtenstein, Italy, Austria and the U.S. For almost two decades, Audi fosters golf sport: for example with the Audi quattro Cup and the HypoVereinsbank Ladies German Open presented by Audi. In sailing, Audi is engaged in the Medcup regatta and supports the team Luna Rossa during the Louis Vuitton Pacific Series and also is the primary sponsor of the Melges 20 sailboat. Further, Audi sponsors the regional teams ERC Ingolstadt (hockey) and FC Ingolstadt 04 (soccer). In 2009, the year of Audi's 100th anniversary, the company organized the Audi Cup for the first time. Audi also sponsor the New York Yankees as well. In October 2010 they agreed to a three sponsorship year-deal with Everton. Audi also sponsors the England Polo Team and holds the Audi Polo Awards. Marvel Cinematic Universe Since the start of the Marvel Cinematic Universe, Audi signed a deal to sponsor, promote and provide vehicles for several films. So far these have been, Iron Man, Iron Man 2, Iron Man 3, Avengers: Age of Ultron, Captain America: Civil War, Spider-Man: Homecoming, Avengers: Endgame and Spider-Man: Far From Home. The R8 supercar became the personal vehicle for Tony Stark (played by Robert Downey Jr.) for six of these films. The e-tron vehicles were promoted in Endgame and Far From Home. Several commercials were co-produced by Marvel and Audi to promote several new concepts and some of the latest vehicles such as the A8, SQ7 and the e-Tron fleet. Multitronic campaign In 2001, Audi promoted the new multitronic continuously variable transmission with television commercials throughout Europe, featuring an impersonator of musician and actor Elvis Presley. A prototypical dashboard figure – later named "Wackel-Elvis" ("Wobble Elvis" or "Wobbly Elvis") – appeared in the commercials to demonstrate the smooth ride in an Audi equipped with the multitronic transmission. The dashboard figure was originally intended for use in the commercials only, but after they aired the demand for Wackel-Elvis fans grew among fans and the figure was mass-produced in China and marketed by Audi in their factory outlet store. Audi TDI As part of Audi's attempt to promote its Diesel technology in 2009, the company began Audi Mileage Marathon. The driving tour featured a fleet of 23 Audi TDI vehicles from 4 models (Audi Q7 3.0 TDI, Audi Q5 3.0 TDI, Audi A4 3.0 TDI, Audi A3 Sportback 2.0 TDI with S tronic transmission) travelling across the American continent from New York to Los Angeles, passing major cities like Chicago, Dallas and Las Vegas during the 13 daily stages, as well as natural wonders including the Rocky Mountains, Death Valley and the Grand Canyon. Audi e-tron The next phase of technology Audi is developing is the e-tron electric drive powertrain system. They have shown several concept cars , each with different levels of size and performance. The original e-tron concept shown at the 2009 Frankfurt motor show is based on the platform of the R8 and has been scheduled for limited production. Power is provided by electric motors at all four wheels. The second concept was shown at the 2010 Detroit Motor Show. Power is provided by two electric motors at the rear axle. This concept is also considered to be the direction for a future mid-engined gas-powered 2-seat performance coupe. The Audi A1 e-tron concept, based on the Audi A1 production model, is a hybrid vehicle with a range extending Wankel rotary engine to provide power after the initial charge of the battery is depleted. It is the only concept of the three to have range-extending capability. The car is powered through the front wheels, always using electric power. It is all set to be displayed at the Auto Expo 2012 in New Delhi, India, from 5 January. Powered by a 1.4 litre engine, and can cover a distance up to 54 km s on a single charge. The e-tron was also shown in the 2013 blockbuster film Iron Man 3 and was driven by Tony Stark (Iron Man). In video games Audi has supported the European version of PlayStation Home, the PlayStation 3's online community-based service, by releasing a dedicated Home space. Audi is the first carmaker to develop such a space for Home. On 17 December 2009, Audi released two spaces; the Audi Home Terminal and the Audi Vertical Run. The Audi Home Terminal features an Audi TV channel delivering video content, an Internet Browser feature, and a view of a city. The Audi Vertical Run is where users can access the mini-game Vertical Run, a futuristic mini-game featuring Audi's e-tron concept. Players collect energy and race for the highest possible speeds and the fastest players earn a place in the Audi apartments located in a large tower in the centre of the Audi Space. In both the Home Terminal and Vertical Run spaces, there are teleports where users can teleport back and forth between the two spaces. Audi had stated that additional content would be added in 2010. On 31 March 2015 Sony shutdown the PlayStation Home service rendering all content for it inaccessible.

Aircraft

An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called aviation. The science of aviation, including designing and building aircraft, is called aeronautics. Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air balloons developed in the 18th century. Each of the two World Wars led to great technical advances. Consequently, the history of aircraft can be divided into five eras: Pioneers of flight, from the earliest experiments to 1914. First World War, 1914 to 1918. Aviation between the World Wars, 1918 to 1939. Second World War, 1939 to 1945. Postwar era, also called the Jet Age, 1945 to the present day. Methods of lift Lighter than air – aerostats Aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large cells or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, it adds up to the same weight as the air that the craft displaces. Small hot-air balloons, called sky lanterns, were first invented in ancient China prior to the 3rd century BC and used primarily in cultural celebrations, and were only the second type of aircraft to fly, the first being kites, which were first invented in ancient China over two thousand years ago. (See Han Dynasty) A balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs — usually fixed-wing. In 1919, Frederick Handley Page was reported as referring to "ships of the air," with smaller passenger types as "Air yachts." In the 1930s, large intercontinental flying boats were also sometimes referred to as "ships of the air" or "flying-ships". — though none had yet been built. The advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by a rigid outer framework and separate aerodynamic skin surrounding the gas bags, were produced, the Zeppelins being the largest and most famous. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, so "airship" came to be synonymous with these aircraft. Then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a "balloon" is an unpowered aerostat and an "airship" is a powered one. A powered, steerable aerostat is called a dirigible. Sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship (which may then be rigid or non-rigid). Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back. These soon became known as blimps. During World War II, this shape was widely adopted for tethered balloons; in windy weather, this both reduces the strain on the tether and stabilizes the balloon. The nickname blimp was adopted along with the shape. In modern times, any small dirigible or airship is called a blimp, though a blimp may be unpowered as well as powered. Heavier-than-air – aerodynes Heavier-than-air aircraft, such as airplanes, must find some way to push air or gas downwards so that a reaction occurs (by Newton's laws of motion) to push the aircraft upwards. This dynamic movement through the air is the origin of the term. There are two ways to produce dynamic upthrust — aerodynamic lift, and powered lift in the form of engine thrust. Aerodynamic lift involving wings is the most common, with fixed-wing aircraft being kept in the air by the forward movement of wings, and rotorcraft by spinning wing-shaped rotors sometimes called "rotary wings." A wing is a flat, horizontal surface, usually shaped in cross-section as an aerofoil. To fly, air must flow over the wing and generate lift. A flexible wing is a wing made of fabric or thin sheet material, often stretched over a rigid frame. A kite is tethered to the ground and relies on the speed of the wind over its wings, which may be flexible or rigid, fixed, or rotary. With powered lift, the aircraft directs its engine thrust vertically downward. V/STOL aircraft, such as the Harrier jump jet and Lockheed Martin F-35B take off and land vertically using powered lift and transfer to aerodynamic lift in steady flight. A pure rocket is not usually regarded as an aerodyne because it does not depend on the air for its lift (and can even fly into space); however, many aerodynamic lift vehicles have been powered or assisted by rocket motors. Rocket-powered missiles that obtain aerodynamic lift at very high speed due to airflow over their bodies are a marginal case. Fixed-wing The forerunner of the fixed-wing aircraft is the kite. Whereas a fixed-wing aircraft relies on its forward speed to create airflow over the wings, a kite is tethered to the ground and relies on the wind blowing over its wings to provide lift. Kites were the first kind of aircraft to fly and were invented in China around 500 BC. Much aerodynamic research was done with kites before test aircraft, wind tunnels, and computer modelling programs became available. The first heavier-than-air craft capable of controlled free-flight were gliders. A glider designed by George Cayley carried out the first true manned, controlled flight in 1853. The practical, powered, fixed-wing aircraft (the airplane or aeroplane) was invented by Wilbur and Orville Wright. Besides the method of propulsion, fixed-wing aircraft are in general characterized by their wing configuration. The most important wing characteristics are: Number of wings — monoplane, biplane, etc. Wing support — Braced or cantilever, rigid, or flexible. Wing planform — including aspect ratio, angle of sweep, and any variations along the span (including the important class of delta wings). Location of the horizontal stabilizer, if any. Dihedral angle — positive, zero, or negative (anhedral). A variable geometry aircraft can change its wing configuration during flight. A flying wing has no fuselage, though it may have small blisters or pods. The opposite of this is a lifting body, which has no wings, though it may have small stabilizing and control surfaces. Wing-in-ground-effect vehicles are generally not considered aircraft. They "fly" efficiently close to the surface of the ground or water, like conventional aircraft during takeoff. An example is the Russian ekranoplan nicknamed the "Caspian Sea Monster". Man-powered aircraft also rely on ground effect to remain airborne with minimal pilot power, but this is only because they are so underpowered—in fact, the airframe is capable of flying higher. Rotorcraft Rotorcraft, or rotary-wing aircraft, use a spinning rotor with aerofoil cross-section blades (a rotary wing) to provide lift. Types include helicopters, autogyros, and various hybrids such as gyrodynes and compound rotorcraft. Helicopters have a rotor turned by an engine-driven shaft. The rotor pushes air downward to create lift. By tilting the rotor forward, the downward flow is tilted backward, producing thrust for forward flight. Some helicopters have more than one rotor and a few have rotors turned by gas jets at the tips. Some have a tail rotor to counteract the rotation of the main rotor, and to aid directional control. Autogyros have unpowered rotors, with a separate power plant to provide thrust. The rotor is tilted backward. As the autogyro moves forward, air blows upward across the rotor, making it spin. This spinning increases the speed of airflow over the rotor, to provide lift. Rotor kites are unpowered autogyros, which are towed to give them forward speed or tethered to a static anchor in high-wind for kited flight. Cyclogyros rotate their wings about a horizontal axis. Compound rotorcraft have wings that provide some or all of the lift in forward flight. They are nowadays classified as powered lift types and not as rotorcraft. Tiltrotor aircraft (such as the Bell Boeing V-22 Osprey), tiltwing, tail-sitter, and coleopter aircraft have their rotors/propellers horizontal for vertical flight and vertical for forward flight. Other methods of lift A lifting body is an aircraft body shaped to produce lift. If there are any wings, they are too small to provide significant lift and are used only for stability and control. Lifting bodies are not efficient: they suffer from high drag, and must also travel at high speed to generate enough lift to fly. Many of the research prototypes, such as the Martin Marietta X-24, which led up to the Space Shuttle, were lifting bodies, though the Space Shuttle is not, and some supersonic missiles obtain lift from the airflow over a tubular body. Powered lift types rely on engine-derived lift for vertical takeoff and landing (VTOL). Most types transition to fixed-wing lift for horizontal flight. Classes of powered lift types include VTOL jet aircraft (such as the Harrier jump jet) and tiltrotors, such as the Bell Boeing V-22 Osprey, among others. A few experimental designs rely entirely on engine thrust to provide lift throughout the whole flight, including personal fan-lift hover platforms and jetpacks. VTOL research designs include the Rolls-Royce Thrust Measuring Rig. The Flettner airplane uses a rotating cylinder in place of a fixed wing, obtaining lift from the Magnus effect. The ornithopter obtains thrust by flapping its wings. Size and speed extremes Size The smallest aircraft are toys/recreational items, and nano aircraft. The largest aircraft by dimensions and volume (as of 2016) is the long British Airlander 10, a hybrid blimp, with helicopter and fixed-wing features, and reportedly capable of speeds up to , and an airborne endurance of two weeks with a payload of up to . The largest aircraft by weight and largest regular fixed-wing aircraft ever built, , was the Antonov An-225 Mriya. That Soviet-built (Ukrainian SSR) six-engine transport of the 1980s was long, with an wingspan. It holds the world payload record, after transporting of goods, and has flown loads commercially. With a maximum loaded weight of , it was also the heaviest aircraft built to date. It could cruise at . The aircraft was destroyed during the Russo-Ukrainian War. The largest military airplanes are the Ukrainian Antonov An-124 Ruslan (world's second-largest airplane, also used as a civilian transport), and American Lockheed C-5 Galaxy transport, weighing, loaded, over . The 8-engine, piston/propeller Hughes H-4 Hercules "Spruce Goose" — an American World War II wooden flying boat transport with a greater wingspan (94m/260ft) than any current aircraft and a tail height equal to the tallest (Airbus A380-800 at 24.1m/78ft) — flew only one short hop in the late 1940s and never flew out of ground effect. The largest civilian airplanes, apart from the above-noted An-225 and An-124, are the Airbus Beluga cargo transport derivative of the Airbus A300 jet airliner, the Boeing Dreamlifter cargo transport derivative of the Boeing 747 jet airliner/transport (the 747-200B was, at its creation in the 1960s, the heaviest aircraft ever built, with a maximum weight of over ), and the double-decker Airbus A380 "super-jumbo" jet airliner (the world's largest passenger airliner). Speeds The fastest fixed-wing aircraft and fastest glider, is the Space Shuttle, which re-entered the atmosphere at nearly Mach 25 or The fastest recorded powered aircraft flight and fastest recorded aircraft flight of an air-breathing powered aircraft was of the NASA X-43A Pegasus, a scramjet-powered, hypersonic, lifting body experimental research aircraft, at Mach 9.68 or on 16 November 2004. Prior to the X-43A, the fastest recorded powered airplane flight, and still the record for the fastest manned powered airplane, was the North American X-15, rocket-powered airplane at Mach 6.7 or 7,274 km/h (4,520 mph) on 3 October 1967. The fastest manned, air-breathing powered airplane is the Lockheed SR-71 Blackbird, a U.S. reconnaissance jet fixed-wing aircraft, having reached on 28 July 1976. Propulsion Unpowered aircraft Gliders are heavier-than-air aircraft that do not employ propulsion once airborne. Take-off may be by launching forward and downward from a high location, or by pulling into the air on a tow-line, either by a ground-based winch or vehicle, or by a powered "tug" aircraft. For a glider to maintain its forward air speed and lift, it must descend in relation to the air (but not necessarily in relation to the ground). Many gliders can "soar", i.e., gain height from updrafts such as thermal currents. The first practical, controllable example was designed and built by the British scientist and pioneer George Cayley, whom many recognise as the first aeronautical engineer. Common examples of gliders are sailplanes, hang gliders and paragliders. Balloons drift with the wind, though normally the pilot can control the altitude, either by heating the air or by releasing ballast, giving some directional control (since the wind direction changes with altitude). A wing-shaped hybrid balloon can glide directionally when rising or falling; but a spherically shaped balloon does not have such directional control. Kites are aircraft that are tethered to the ground or other object (fixed or mobile) that maintains tension in the tether or kite line; they rely on virtual or real wind blowing over and under them to generate lift and drag. Kytoons are balloon-kite hybrids that are shaped and tethered to obtain kiting deflections, and can be lighter-than-air, neutrally buoyant, or heavier-than-air. Powered aircraft Powered aircraft have one or more onboard sources of mechanical power, typically aircraft engines although rubber and manpower have also been used. Most aircraft engines are either lightweight reciprocating engines or gas turbines. Engine fuel is stored in tanks, usually in the wings but larger aircraft also have additional fuel tanks in the fuselage. Propeller aircraft Propeller aircraft use one or more propellers (airscrews) to create thrust in a forward direction. The propeller is usually mounted in front of the power source in tractor configuration but can be mounted behind in pusher configuration. Variations of propeller layout include contra-rotating propellers and ducted fans. Many kinds of power plant have been used to drive propellers. Early airships used man power or steam engines. The more practical internal combustion piston engine was used for virtually all fixed-wing aircraft until World War II and is still used in many smaller aircraft. Some types use turbine engines to drive a propeller in the form of a turboprop or propfan. Human-powered flight has been achieved, but has not become a practical means of transport. Unmanned aircraft and models have also used power sources such as electric motors and rubber bands. Jet aircraft Jet aircraft use airbreathing jet engines, which take in air, burn fuel with it in a combustion chamber, and accelerate the exhaust rearwards to provide thrust. Different jet engine configurations include the turbojet and turbofan, sometimes with the addition of an afterburner. Those with no rotating turbomachinery include the pulsejet and ramjet. These mechanically simple engines produce no thrust when stationary, so the aircraft must be launched to flying speed using a catapult, like the V-1 flying bomb, or a rocket, for example. Other engine types include the motorjet and the dual-cycle Pratt & Whitney J58. Compared to engines using propellers, jet engines can provide much higher thrust, higher speeds and, above about , greater efficiency. They are also much more fuel-efficient than rockets. As a consequence nearly all large, high-speed or high-altitude aircraft use jet engines. Rotorcraft Some rotorcraft, such as helicopters, have a powered rotary wing or rotor, where the rotor disc can be angled slightly forward so that a proportion of its lift is directed forwards. The rotor may, like a propeller, be powered by a variety of methods such as a piston engine or turbine. Experiments have also used jet nozzles at the rotor blade tips. Other types of powered aircraft Rocket-powered aircraft have occasionally been experimented with, and the Messerschmitt Me 163 Komet fighter even saw action in the Second World War. Since then, they have been restricted to research aircraft, such as the North American X-15, which traveled up into space where air-breathing engines cannot work (rockets carry their own oxidant). Rockets have more often been used as a supplement to the main power plant, typically for the rocket-assisted take off of heavily loaded aircraft, but also to provide high-speed dash capability in some hybrid designs such as the Saunders-Roe SR.53. The ornithopter obtains thrust by flapping its wings. It has found practical use in a model hawk used to freeze prey animals into stillness so that they can be captured, and in toy birds. Design and construction Aircraft are designed according to many factors such as customer and manufacturer demand, safety protocols and physical and economic constraints. For many types of aircraft the design process is regulated by national airworthiness authorities. The key parts of an aircraft are generally divided into three categories: The structure ("airframe") comprises the main load-bearing elements and associated equipment, as well as flight controls. The propulsion system ("powerplant") (if it is powered) comprises the power source and associated equipment, as described above. The avionics comprise the electrical and electronic control, navigation and communication systems. Structure The approach to structural design varies widely between different types of aircraft. Some, such as paragliders, comprise only flexible materials that act in tension and rely on aerodynamic pressure to hold their shape. A balloon similarly relies on internal gas pressure, but may have a rigid basket or gondola slung below it to carry its payload. Early aircraft, including airships, often employed flexible doped aircraft fabric covering to give a reasonably smooth aeroshell stretched over a rigid frame. Later aircraft employed semi-monocoque techniques, where the skin of the aircraft is stiff enough to share much of the flight loads. In a true monocoque design there is no internal structure left. With the recent emphasis on sustainability hemp has picked up some attention, having a way smaller carbon foot print and 10 times stronger than steel, hemp could become the standard of manufacturing in the future. The key structural parts of an aircraft depend on what type it is. Aerostats Lighter-than-air types are characterised by one or more gasbags, typically with a supporting structure of flexible cables or a rigid framework called its hull. Other elements such as engines or a gondola may also be attached to the supporting structure. Aerodynes Heavier-than-air types are characterised by one or more wings and a central fuselage. The fuselage typically also carries a tail or empennage for stability and control, and an undercarriage for takeoff and landing. Engines may be located on the fuselage or wings. On a fixed-wing aircraft the wings are rigidly attached to the fuselage, while on a rotorcraft the wings are attached to a rotating vertical shaft. Smaller designs sometimes use flexible materials for part or all of the structure, held in place either by a rigid frame or by air pressure. The fixed parts of the structure comprise the airframe. Power The source of motive power for an aircraft is normally called the powerplant, and includes engine or motor, propeller or rotor, (if any), jet nozzles and thrust reversers (if any), and accessories essential to the functioning of the engine or motor (e.g.: starter, ignition system, intake system, exhaust system, fuel system, lubrication system, engine cooling system, and engine controls). Powered aircraft are typically powered by internal combustion engines (piston or turbine) burning fossil fuels -- typically gasoline (avgas) or jet fuel. A very few are powered by rocket power, ramjet propulsion, or by electric motors, or by internal combustion engines of other types, or using other fuels. A very few have been powered, for short flights, by human muscle energy (e.g.: Gossamer Condor). Avionics The avionics comprise any electronic aircraft flight control systems and related equipment, including electronic cockpit instrumentation, navigation, radar, monitoring, and communications systems. Flight characteristics Flight envelope The flight envelope of an aircraft refers to its approved design capabilities in terms of airspeed, load factor and altitude. The term can also refer to other assessments of aircraft performance such as maneuverability. When an aircraft is abused, for instance by diving it at too-high a speed, it is said to be flown outside the envelope, something considered foolhardy since it has been taken beyond the design limits which have been established by the manufacturer. Going beyond the envelope may have a known outcome such as flutter or entry to a non-recoverable spin (possible reasons for the boundary). Range The range is the distance an aircraft can fly between takeoff and landing, as limited by the time it can remain airborne. For a powered aircraft the time limit is determined by the fuel load and rate of consumption. For an unpowered aircraft, the maximum flight time is limited by factors such as weather conditions and pilot endurance. Many aircraft types are restricted to daylight hours, while balloons are limited by their supply of lifting gas. The range can be seen as the average ground speed multiplied by the maximum time in the air. The Airbus A350-900ULR is now the longest range airliner. Flight dynamics Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation around three axes which pass through the vehicle's center of gravity, known as pitch, roll, and yaw. Roll is a rotation about the longitudinal axis (equivalent to the rolling or heeling of a ship) giving an up-down movement of the wing tips measured by the roll or bank angle. Pitch is a rotation about the sideways horizontal axis giving an up-down movement of the aircraft nose measured by the angle of attack. Yaw is a rotation about the vertical axis giving a side-to-side movement of the nose known as sideslip. Flight dynamics is concerned with the stability and control of an aircraft's rotation about each of these axes. Stability An aircraft that is unstable tends to diverge from its intended flight path and so is difficult to fly. A very stable aircraft tends to stay on its flight path and is difficult to maneuver. Therefore, it is important for any design to achieve the desired degree of stability. Since the widespread use of digital computers, it is increasingly common for designs to be inherently unstable and rely on computerised control systems to provide artificial stability. A fixed wing is typically unstable in pitch, roll, and yaw. Pitch and yaw stabilities of conventional fixed wing designs require horizontal and vertical stabilisers, which act similarly to the feathers on an arrow. These stabilizing surfaces allow equilibrium of aerodynamic forces and to stabilise the flight dynamics of pitch and yaw. They are usually mounted on the tail section (empennage), although in the canard layout, the main aft wing replaces the canard foreplane as pitch stabilizer. Tandem wing and tailless aircraft rely on the same general rule to achieve stability, the aft surface being the stabilising one. A rotary wing is typically unstable in yaw, requiring a vertical stabiliser. A balloon is typically very stable in pitch and roll due to the way the payload is slung underneath the center of lift. Control Flight control surfaces enable the pilot to control an aircraft's flight attitude and are usually part of the wing or mounted on, or integral with, the associated stabilizing surface. Their development was a critical advance in the history of aircraft, which had until that point been uncontrollable in flight. Aerospace engineers develop control systems for a vehicle's orientation (attitude) about its center of mass. The control systems include actuators, which exert forces in various directions, and generate rotational forces or moments about the aerodynamic center of the aircraft, and thus rotate the aircraft in pitch, roll, or yaw. For example, a pitching moment is a vertical force applied at a distance forward or aft from the aerodynamic center of the aircraft, causing the aircraft to pitch up or down. Control systems are also sometimes used to increase or decrease drag, for example to slow the aircraft to a safe speed for landing. The two main aerodynamic forces acting on any aircraft are lift supporting it in the air and drag opposing its motion. Control surfaces or other techniques may also be used to affect these forces directly, without inducing any rotation. Impacts of aircraft use Aircraft permit long distance, high speed travel and may be a more fuel efficient mode of transportation in some circumstances. Aircraft have environmental and climate impacts beyond fuel efficiency considerations, however. They are also relatively noisy compared to other forms of travel and high altitude aircraft generate contrails, which experimental evidence suggests may alter weather patterns. Uses for aircraft Aircraft are produced in several different types optimized for various uses; military aircraft, which includes not just combat types but many types of supporting aircraft, and civil aircraft, which include all non-military types, experimental and model. Military A military aircraft is any aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat: Combat aircraft are aircraft designed to destroy enemy equipment using its own armament. Combat aircraft divide broadly into fighters and bombers, with several in-between types, such as fighter-bombers and attack aircraft, including attack helicopters. Non-combat aircraft are not designed for combat as their primary function, but may carry weapons for self-defense. Non-combat roles include search and rescue, reconnaissance, observation, transport, training, and aerial refueling. These aircraft are often variants of civil aircraft. Most military aircraft are powered heavier-than-air types. Other types, such as gliders and balloons, have also been used as military aircraft; for example, balloons were used for observation during the American Civil War and World War I, and military gliders were used during World War II to land troops. Civil Civil aircraft divide into commercial and general types, however there are some overlaps. Commercial aircraft include types designed for scheduled and charter airline flights, carrying passengers, mail and other cargo. The larger passenger-carrying types are the airliners, the largest of which are wide-body aircraft. Some of the smaller types are also used in general aviation, and some of the larger types are used as VIP aircraft. General aviation is a catch-all covering other kinds of private (where the pilot is not paid for time or expenses) and commercial use, and involving a wide range of aircraft types such as business jets (bizjets), trainers, homebuilt, gliders, warbirds and hot air balloons to name a few. The vast majority of aircraft today are general aviation types. Experimental An experimental aircraft is one that has not been fully proven in flight, or that carries a Special Airworthiness Certificate, called an Experimental Certificate in United States parlance. This often implies that the aircraft is testing new aerospace technologies, though the term also refers to amateur-built and kit-built aircraft, many of which are based on proven designs. Model A model aircraft is a small unmanned type made to fly for fun, for static display, for aerodynamic research or for other purposes. A scale model is a replica of some larger design.

Alfred Nobel

Alfred Bernhard Nobel ( , ; 21 October 1833 – 10 December 1896) was a Swedish chemist, engineer, inventor, businessman, and philanthropist. He is best known for having bequeathed his fortune to establish the Nobel Prize, though he also made several important contributions to science, holding 355 patents in his lifetime. Nobel's most famous invention was dynamite, a safer and easier means of harnessing the explosive power of nitroglycerin; it was patented in 1867. Nobel displayed an early aptitude for science and learning, particularly in chemistry and languages; he became fluent in six languages and filed his first patent at age 24. He embarked on many business ventures with his family, most notably owning Bofors, an iron and steel producer that he developed into a major manufacturer of cannons and other armaments. Nobel was later inspired to donate his fortune to the Nobel Prize institution, which would annually recognize those who "conferred the greatest benefit to humankind". The synthetic element nobelium was named after him, and his name and legacy also survives in companies such as Dynamit Nobel and AkzoNobel, which descend from mergers with companies he founded. Nobel was elected a member of the Royal Swedish Academy of Sciences, which, pursuant to his will, would be responsible for choosing the Nobel laureates in physics and in chemistry. Personal life Early life and education Alfred Nobel was born in Stockholm, United Kingdoms of Sweden and Norway on 21 October 1833. He was the third son of Immanuel Nobel (1801–1872), an inventor and engineer, and Karolina Andriette Nobel (née Ahlsell 1805–1889). The couple married in 1827 and had eight children. The family was impoverished and only Alfred and his three brothers survived beyond childhood. Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702), and in his turn, the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age. Alfred Nobel's interest in technology was inherited from his father, an alumnus of Royal Institute of Technology in Stockholm.Following various business failures, Nobel's father moved to Saint Petersburg, Russia and grew successful there as a manufacturer of machine tools and explosives. He invented the veneer lathe (which made possible the production of modern plywood) and started work on the torpedo. In 1842, the family joined him in the city. Now prosperous, his parents were able to send Nobel to private tutors and the boy excelled in his studies, particularly in chemistry and languages, achieving fluency in English, French, German and Russian. For 18 months, from 1841 to 1842, Nobel went to the only school he ever attended as a child, in Stockholm. Nobel gained proficiency in Swedish, French, Russian, English, German, and Italian. He also developed sufficient literary skill to write poetry in English. His Nemesis is a prose tragedy in four acts about the Italian noblewoman Beatrice Cenci. It was printed while he was dying, but the entire stock was destroyed immediately after his death except for three copies, being regarded as scandalous and blasphemous. It was published in Sweden in 2003 and has been translated into Slovenian, French, Italian, and Spanish. Religion Nobel was Lutheran and regularly attended the Church of Sweden Abroad during his Paris years, led by pastor Nathan Söderblom who received the Nobel Peace Prize in 1930. He became an agnostic in youth and was an atheist later in life, though still donated generously to the Church. Health and relationships Nobel travelled for much of his business life, maintaining companies in Europe and America while keeping a home in Paris from 1873 to 1891. He remained a solitary character, given to periods of depression. He remained unmarried, although his biographers note that he had at least three loves, the first in Russia with a girl named Alexandra who rejected his proposal. In 1876, Austro-Bohemian Countess Bertha Kinsky became his secretary, but she left him after a brief stay to marry her previous lover Baron Arthur Gundaccar von Suttner. Her contact with Nobel was brief, yet she corresponded with him until his death in 1896, and probably influenced his decision to include a peace prize in his will. She was awarded the 1905 Nobel Peace prize "for her sincere peace activities". Nobel's longest-lasting relationship was with Sofija Hess from Celje whom he met in 1876. The liaison lasted for 18 years. Residences In the years of 1865 to 1873, Alfred Nobel had his home in Krümmel, Hamburg, he afterward moved to a house in the Avenue Malakoff in Paris that same year. In 1894, when he acquired Bofors-Gullspång, the Björkborn Manor was included, he stayed at his manor house in Sweden during the summers. The manor house became his very last residence in Sweden and has after his death functioned as a museum. Alfred Nobel died on 10 December 1896, in Sanremo, Italy, at his very last residence, Villa Nobel, overlooking the Mediterranean Sea. Scientific career As a young man, Nobel studied with chemist Nikolai Zinin; then, in 1850, went to Paris to further the work. There he met Ascanio Sobrero, who had invented nitroglycerin three years before. Sobrero strongly opposed the use of nitroglycerin because it was unpredictable, exploding when subjected to variable heat or pressure. But Nobel became interested in finding a way to control and use nitroglycerin as a commercially usable explosive; it had much more power than gunpowder. In 1851 at age 18, he went to the United States for one year to study, working for a short period under Swedish-American inventor John Ericsson, who designed the American Civil War ironclad, USS Monitor. Nobel filed his first patent, an English patent for a gas meter, in 1857, while his first Swedish patent, which he received in 1863, was on "ways to prepare gunpowder".The family factory produced armaments for the Crimean War (1853–1856), but had difficulty switching back to regular domestic production when the fighting ended and they filed for bankruptcy. In 1859, Nobel's father left his factory in the care of the second son, Ludvig Nobel (1831–1888), who greatly improved the business. Nobel and his parents returned to Sweden from Russia and Nobel devoted himself to the study of explosives, and especially to the safe manufacture and use of nitroglycerin. Nobel invented a detonator in 1863, and in 1865 designed the blasting cap. On 3 September 1864, a shed used for preparation of nitroglycerin exploded at the factory in Heleneborg, Stockholm, Sweden, killing five people, including Nobel's younger brother Emil. Fazed by the accident, Nobel founded the company Nitroglycerin Aktiebolaget AB in Vinterviken so that he could continue to work in a more isolated area. Nobel invented dynamite in 1867, a substance easier and safer to handle than the more unstable nitroglycerin. Dynamite was patented in the US and the UK and was used extensively in mining and the building of transport networks internationally. In 1875, Nobel invented gelignite, more stable and powerful than dynamite, and in 1887, patented ballistite, a predecessor of cordite. Nobel was elected a member of the Royal Swedish Academy of Sciences in 1884, the same institution that would later select laureates for two of the Nobel prizes, and he received an honorary doctorate from Uppsala University in 1893. Nobel's brothers Ludvig and Robert founded the oil company Branobel and became hugely rich in their own right. Nobel invested in these and amassed great wealth through the development of these new oil regions. During his life, Nobel was issued 355 patents internationally, and by his death, his business had established more than 90 armaments factories, despite his apparently pacifist character. Inventions Nobel found that when nitroglycerin was incorporated in an absorbent inert substance like kieselguhr (diatomaceous earth) it became safer and more convenient to handle, and this mixture he patented in 1867 as "dynamite". Nobel demonstrated his explosive for the first time that year, at a quarry in Redhill, Surrey, England. In order to help reestablish his name and improve the image of his business from the earlier controversies associated with dangerous explosives, Nobel had also considered naming the highly powerful substance "Nobel's Safety Powder", but settled with Dynamite instead, referring to the Greek word for "power" (). Nobel later combined nitroglycerin with various nitrocellulose compounds, similar to collodion, but settled on a more efficient recipe combining another nitrate explosive, and obtained a transparent, jelly-like substance, which was a more powerful explosive than dynamite. Gelignite, or blasting gelatine, as it was named, was patented in 1876; and was followed by a host of similar combinations, modified by the addition of potassium nitrate and various other substances. Gelignite was more stable, transportable and conveniently formed to fit into bored holes, like those used in drilling and mining, than the previously used compounds. It was adopted as the standard technology for mining in the "Age of Engineering", bringing Nobel a great amount of financial success, though at a cost to his health. An offshoot of this research resulted in Nobel's invention of ballistite, the precursor of many modern smokeless powder explosives and still used as a rocket propellant. Nobel Prize There is a well known story about the origin of the Nobel Prize. In 1888, the death of his brother Ludvig supposedly caused several newspapers to publish obituaries of Alfred in error. One French newspaper condemned him for his invention of military explosives—in many versions of the story, dynamite is quoted, although this was mainly used for civilian applications—and this is said to have brought about his decision to leave a better legacy after his death. The obituary stated, ("The merchant of death is dead"), and went on to say, "Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday." Nobel read the obituary and was appalled at the idea that he would be remembered in this way. His decision to posthumously donate the majority of his wealth to found the Nobel Prize has been credited to him wanting to leave behind a better legacy. However, it has been questioned whether or not the obituary in question actually existed. On 27 November 1895, at the Swedish-Norwegian Club in Paris, Nobel signed his last will and testament and set aside the bulk of his estate to establish the Nobel Prizes, to be awarded annually without distinction of nationality. After taxes and bequests to individuals, Nobel's will allocated 94% of his total assets, 31,225,000 Swedish kronor, to establish the five Nobel Prizes. This converted to £1,687,837 (GBP) at the time. In 2012, the capital was worth around SEK 3.1 billion (US$472 million, EUR 337 million), which is almost twice the amount of the initial capital, taking inflation into account. The first three of these prizes are awarded for eminence in physical science, in chemistry and in medical science or physiology; the fourth is for literary work "in an ideal direction" and the fifth prize is to be given to the person or society that renders the greatest service to the cause of international fraternity, in the suppression or reduction of standing armies, or in the establishment or furtherance of peace congresses. The formulation for the literary prize being given for a work "in an ideal direction" ( in Swedish), is cryptic and has caused much confusion. For many years, the Swedish Academy interpreted "ideal" as "idealistic" () and used it as a reason not to give the prize to important but less romantic authors, such as Henrik Ibsen and Leo Tolstoy. This interpretation has since been revised, and the prize has been awarded to, for example, Dario Fo and José Saramago, who do not belong to the camp of literary idealism. There was room for interpretation by the bodies he had named for deciding on the physical sciences and chemistry prizes, given that he had not consulted them before making the will. In his one-page testament, he stipulated that the money go to discoveries or inventions in the physical sciences and to discoveries or improvements in chemistry. He had opened the door to technological awards, but had not left instructions on how to deal with the distinction between science and technology. Since the deciding bodies he had chosen were more concerned with the former, the prizes went to scientists more often than engineers, technicians or other inventors. Sweden's central bank Sveriges Riksbank celebrated its 300th anniversary in 1968 by donating a large sum of money to the Nobel Foundation to be used to set up a sixth prize in the field of economics in honour of Alfred Nobel. In 2001, Alfred Nobel's great-great-nephew, Peter Nobel (born 1931), asked the Bank of Sweden to differentiate its award to economists given "in Alfred Nobel's memory" from the five other awards. This request added to the controversy over whether the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel is actually a legitimate "Nobel Prize". Death Nobel was accused of high treason against France for selling Ballistite to Italy, so he moved from Paris to Sanremo, Italy, in 1891. On 10 December 1896, he suffered a stroke and died. He had left most of his wealth in trust, unbeknownst to his family, in order to fund the Nobel Prize awards. He is buried in Norra begravningsplatsen in Stockholm. Monuments and legacy The Monument to Alfred Nobel (, ) in Saint Petersburg is located along the Bolshaya Nevka River on Petrogradskaya Embankment. It was dedicated in 1991 to mark the 90th anniversary of the first Nobel Prize presentation. Diplomat Thomas Bertelman and Professor Arkady Melua were initiators of the creation of the monument (1989). Professor A. Melua has provided funds for the establishment of the monument (J.S.Co. "Humanistica", 1990–1991). The abstract metal sculpture was designed by local artists Sergey Alipov and Pavel Shevchenko, and appears to be an explosion or branches of a tree. Petrogradskaya Embankment is the street where Nobel's family lived until 1859. Criticism of Nobel focuses on his leading role in weapons manufacturing and sales, and some question his motives in creating his prizes, suggesting they are intended to improve his reputation.

https://en.wikipedia.org/wiki/Anatolia

Anatolia

Anatolia, also known as Asia Minor, is a large peninsula in Western Asia and is the western-most extension of continental Asia. The land mass of Anatolia constitutes most of the territory of contemporary Turkey. Geographically, the Anatolian region is bounded by the Turkish Straits to the north-west, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. Topographically, the Sea of Marmara connects the Black Sea with the Aegean Sea through the Bosporus strait and the Dardanelles strait, and separates Anatolia from Thrace in the Balkan peninsula of Southeastern Europe. The eastern border of Anatolia is a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the south-east, thus Anatolia comprises approximately the western two-thirds of the Asian territory of Turkey. Anatolia sometimes is synonymous with Asian Turkey, thereby including the western part of the Armenian Highlands and northern Mesopotamia and making its eastern and southern borders coterminous with Turkey's borders. The ancient Anatolian peoples spoke the now-extinct Anatolian languages of the Indo-European language family, which were largely replaced by the Greek language during Classical antiquity as well as during the Hellenistic, Roman, and Byzantine periods. The major Anatolian languages included Hittite, Luwian, and Lydian, while other, poorly attested local languages included Phrygian and Mysian. Hurro-Urartian languages were spoken in the southeastern kingdom of Mitanni, while Galatian, a Celtic language, was spoken in Galatia, central Anatolia. The Turkification of Anatolia began under the rule of the Seljuk Empire in the late 11th century, continued under the Ottoman Empire between the late 13th and early 20th centuries, and continues today under the Republic of Turkey. However, various non-Turkic languages continue to be spoken by minorities in Anatolia today, including Kurdish, Neo-Aramaic, Armenian, North Caucasian languages, Laz, Georgian, and Greek. Other ancient peoples in the region included Galatians, Hurrians, Assyrians, Hattians, Cimmerians, as well as Ionian, Dorian, and Aeolic Greeks. Geography Traditionally, Anatolia is considered to extend in the east to an indefinite line running from the Gulf of Alexandretta to the Black Sea, coterminous with the Anatolian Plateau. This traditional geographical definition is used, for example, in the latest edition of Merriam-Webster's Geographical Dictionary. Under this definition, Anatolia is bounded to the east by the Armenian Highlands, and the Euphrates before that river bends to the southeast to enter Mesopotamia. To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria and the Mesopotamian plain. Following the Armenian genocide, Western Armenia was renamed the Eastern Anatolia Region by the newly established Turkish government. In 1941, with the First Geography Congress which divided Turkey into seven geographical regions based on differences in climate and landscape, the eastern provinces of Turkey were placed into the Eastern Anatolia Region, which largely corresponds to the historical region of Western Armenia (named as such after the division of Greater Armenia between the Roman/Byzantine Empire (Western Armenia) and Sassanid Persia (Eastern Armenia) in 387 AD). Vazken Davidian terms the expanded use of "Anatolia" to apply to territory in eastern Turkey that was formerly referred to as Armenia (which had a sizeable Armenian population before the Armenian genocide) an "ahistorical imposition" and notes that a growing body of literature is uncomfortable with referring to the Ottoman East as "Eastern Anatolia". The highest mountain in the Eastern Anatolia Region (also the highest peak in the Armenian Highlands) is Mount Ararat (5123 m). The Euphrates, Araxes, Karasu and Murat rivers connect the Armenian Highlands to the South Caucasus and the Upper Euphrates Valley. Along with the Çoruh, these rivers are the longest in the Eastern Anatolia Region. Etymology The English-language name Anatolia derives from the Greek () meaning "the East" and designating (from a Greek point of view) eastern regions in general. The Greek word refers to the direction where the sun rises, coming from anatello '(Ι) rise up', comparable to terms in other languages such as "levant" from Latin 'to rise', "orient" from Latin 'to arise, to originate', Hebrew mizraḥ 'east' from zaraḥ 'to rise, to shine', Aramaic midnaḥ from denaḥ 'to rise, to shine'. The use of Anatolian designations has varied over time, perhaps originally referring to the Aeolian, Ionian and Dorian colonies situated along the eastern coasts of the Aegean Sea, but also encompassing eastern regions in general. Such use of Anatolian designations was employed during the reign of Roman Emperor Diocletian (), who created the Diocese of the East, known in Greek as the Eastern Diocese, but completely unrelated to the regions of Asia Minor. In their widest territorial scope, Anatolian designations were employed during the reign of Roman Emperor Constantine I (306–337), who created the Praetorian prefecture of the East, known in Greek as the Eastern Prefecture, encompassing all eastern regions of the Late Roman Empire and spanning from Thrace to Egypt. Only after the loss of other eastern regions during the 7th century and the reduction of Byzantine eastern domains to Asia Minor, that region became the only remaining part of the Byzantine East, and thus commonly referred to (in Greek) as the Eastern part of the Empire. At the same time, the Anatolic Theme ( / "the Eastern theme") was created, as a province (theme) covering the western and central parts of Turkey's present-day Central Anatolia Region, centered around Iconium, but ruled from the city of Amorium. The Latinized form "", with its -ia ending, is probably a Medieval Latin innovation. The modern Turkish form derives directly from the Greek name (Anatolḗ). The Russian male name Anatoly, the French Anatole and plain Anatol, all stemming from saints Anatolius of Laodicea (d. 283) and Anatolius of Constantinople (d. 458; the first Patriarch of Constantinople), share the same linguistic origin. Names The oldest known name for any region within Anatolia is related to its central area, known as the "Land of Hatti" – a designation that was initially used for the land of ancient Hattians, but later became the most common name for the entire territory under the rule of ancient Hittites. The first recorded name the Greeks used for the Anatolian peninsula, though not particularly popular at the time, was Ἀσία (Asía), perhaps from an Akkadian expression for the "sunrise" or possibly echoing the name of the Assuwa league in western Anatolia. The Romans used it as the name of their province, comprising the west of the peninsula plus the nearby Aegean Islands. As the name "Asia" broadened its scope to apply to the vaster region east of the Mediterranean, some Greeks in Late Antiquity came to use the name Asia Minor (Μικρὰ Ἀσία, Mikrà Asía), meaning "Lesser Asia" to refer to present-day Anatolia, whereas the administration of the Empire preferred the description Ἀνατολή (Anatolḗ "the East"). The endonym Ῥωμανία (Rōmanía "the land of the Romans, i.e. the Eastern Roman Empire") was understood as another name for the province by the invading Seljuq Turks, who founded a Sultanate of Rûm in 1077. Thus (land of the) Rûm became another name for Anatolia. By the 12th century Europeans had started referring to Anatolia as Turchia. During the era of the Ottoman Empire, mapmakers outside the Empire referred to the mountainous plateau in eastern Anatolia as Armenia. Other contemporary sources called the same area Kurdistan. Geographers have variously used the terms East Anatolian Plateau and Armenian Plateau to refer to the region, although the territory encompassed by each term largely overlaps with the other. According to archaeologist Lori Khatchadourian, this difference in terminology "primarily result[s] from the shifting political fortunes and cultural trajectories of the region since the nineteenth century". Turkey's First Geography Congress in 1941 created two geographical regions of Turkey to the east of the Gulf of Iskenderun-Black Sea line, the Eastern Anatolia Region and the Southeastern Anatolia Region, the former largely corresponding to the western part of the Armenian Highlands, the latter to the northern part of the Mesopotamian plain. According to Richard Hovannisian, this changing of toponyms was "necessary to obscure all evidence" of the Armenian presence as part of the policy of Armenian genocide denial embarked upon by the newly established Turkish government and what Hovannisian calls its "foreign collaborators". History Prehistoric Anatolia Human habitation in Anatolia dates back to the Paleolithic. Neolithic settlements include Çatalhöyük, Çayönü, Nevali Cori, Aşıklı Höyük, Boncuklu Höyük Hacilar, Göbekli Tepe, Norşuntepe, Kosk, and Mersin. Çatalhöyük (7.000 BCE) is considered the most advanced of these. Neolithic Anatolia has been proposed as the homeland of the Indo-European language family, although linguists tend to favour a later origin in the steppes north of the Black Sea. However, it is clear that the Anatolian languages, the earliest attested branch of Indo-European, have been spoken in Anatolia since at least the 19th century BCE. Recent advances in archaeogenetics have confirmed that the spread of agriculture from the Middle East to Europe was strongly correlated with the migration of early farmers from Anatolia about 9,000 years ago, and was not just a cultural exchange. Anatolian Neolithic farmers derived a significant portion of their ancestry from the Anatolian hunter-gatherers, suggesting that agriculture was adopted in site by these hunter-gatherers and not spread by demic diffusion into the region. Ancient Anatolia The earliest historical data related to Anatolia appear during the Bronze Age and continue throughout the Iron Age. The most ancient period in the history of Anatolia spans from the emergence of ancient Hattians, up to the conquest of Anatolia by the Achaemenid Empire in the 6th century BCE. Hattians and Hurrians The earliest historically attested populations of Anatolia were the Hattians in central Anatolia, and Hurrians further to the east. The Hattians were an indigenous people, whose main center was the city of Hattush. Affiliation of Hattian language remains unclear, while Hurrian language belongs to a distinctive family of Hurro-Urartian languages. All of those languages are extinct; relationships with indigenous languages of the Caucasus have been proposed, but are not generally accepted. The region became famous for exporting raw materials. Organized trade between Anatolia and Mesopotamia started to emerge during the period of the Akkadian Empire, and was continued and intensified during the period of the Old Assyrian Empire, between the 21st and the 18th centuries BCE. Assyrian traders were bringing tin and textiles in exchange for copper, silver or gold. Cuneiform records, dated circa 20th century BCE, found in Anatolia at the Assyrian colony of Kanesh, use an advanced system of trading computations and credit lines. Hittite Anatolia (18th–12th century BCE) Unlike the Akkadians and Assyrians, whose Anatolian trading posts were peripheral to their core lands in Mesopotamia, the Hittites were centered at Hattusa (modern Boğazkale) in north-central Anatolia by the 17th century BCE. They were speakers of an Indo-European language, the Hittite language, or nesili (the language of Nesa) in Hittite. The Hittites originated from local ancient cultures that grew in Anatolia, in addition to the arrival of Indo-European languages. Attested for the first time in the Assyrian tablets of Nesa around 2000 BCE, they conquered Hattusa in the 18th century BCE, imposing themselves over Hattian- and Hurrian-speaking populations. According to the widely accepted Kurgan theory on the Proto-Indo-European homeland, however, the Hittites (along with the other Indo-European ancient Anatolians) were themselves relatively recent immigrants to Anatolia from the north. However, they did not necessarily displace the population genetically; they assimilated into the former peoples' culture, preserving the Hittite language. The Hittites adopted the Mesopotamian cuneiform script. In the Late Bronze Age, Hittite New Kingdom () was founded, becoming an empire in the 14th century BCE after the conquest of Kizzuwatna in the south-east and the defeat of the Assuwa league in western Anatolia. The empire reached its height in the 13th century BCE, controlling much of Asia Minor, northwestern Syria, and northwest upper Mesopotamia. However, the Hittite advance toward the Black Sea coast was halted by the semi-nomadic pastoralist and tribal Kaskians, a non-Indo-European people who had earlier displaced the Palaic-speaking Indo-Europeans. Much of the history of the Hittite Empire concerned war with the rival empires of Egypt, Assyria and the Mitanni. The Ancient Egyptians eventually withdrew from the region after failing to gain the upper hand over the Hittites and becoming wary of the power of Assyria, which had destroyed the Mitanni Empire. The Assyrians and Hittites were then left to battle over control of eastern and southern Anatolia and colonial territories in Syria. The Assyrians had better success than the Egyptians, annexing much Hittite (and Hurrian) territory in these regions. Post-Hittite Anatolia (12th–6th century BCE) After 1180 BCE, during the Late Bronze Age collapse, the Hittite Empire disintegrated into several independent Syro-Hittite states, subsequent to losing much territory to the Middle Assyrian Empire and being finally overrun by the Phrygians, another Indo-European people who are believed to have migrated from the Balkans. The Phrygian expansion into southeast Anatolia was eventually halted by the Assyrians, who controlled that region. Luwians Another Indo-European people, the Luwians, rose to prominence in central and western Anatolia BCE. Their language belonged to the same linguistic branch as Hittite. The general consensus amongst scholars is that Luwian was spoken across a large area of western Anatolia, including (possibly) Wilusa (Troy), the Seha River Land (to be identified with the Hermos and/or Kaikos valley), and the kingdom of Mira-Kuwaliya with its core territory of the Maeander valley. From the 9th century BCE, Luwian regions coalesced into a number of states such as Lydia, Caria, and Lycia, all of which had Hellenic influence. Arameans Arameans encroached over the borders of south-central Anatolia in the century or so after the fall of the Hittite empire, and some of the Syro-Hittite states in this region became an amalgam of Hittites and Arameans. These became known as Syro-Hittite states. Neo-Assyrian Empire From the 10th to late 7th centuries BCE, much of Anatolia (particularly the southeastern regions) fell to the Neo-Assyrian Empire, including all of the Syro-Hittite states, Tabal, Kingdom of Commagene, the Cimmerians and Scythians, and swathes of Cappadocia. The Neo-Assyrian empire collapsed due to a bitter series of civil wars followed by a combined attack by Medes, Persians, Scythians and their own Babylonian relations. The last Assyrian city to fall was Harran in southeast Anatolia. This city was the birthplace of the last king of Babylon, the Assyrian Nabonidus and his son and regent Belshazzar. Much of the region then fell to the short-lived Iran-based Median Empire, with the Babylonians and Scythians briefly appropriating some territory. Cimmerian and Scythian invasions From the late 8th century BCE, a new wave of Indo-European-speaking raiders entered northern and northeast Anatolia: the Cimmerians and Scythians. The Cimmerians overran Phrygia and the Scythians threatened to do the same to Urartu and Lydia, before both were finally checked by the Assyrians. Early Greek presence The north-western coast of Anatolia was inhabited by Greeks of the Achaean/Mycenaean culture from the 20th century BCE, related to the Greeks of southeastern Europe and the Aegean. Beginning with the Bronze Age collapse at the end of the 2nd millennium BCE, the west coast of Anatolia was settled by Ionian Greeks, usurping the area of the related but earlier Mycenaean Greeks. Over several centuries, numerous Ancient Greek city-states were established on the coasts of Anatolia. Greeks started Western philosophy on the western coast of Anatolia (Pre-Socratic philosophy). Classical Anatolia In Classical antiquity, Anatolia was described by the Ancient Greek historian Herodotus and later historians as divided into regions that were diverse in culture, language, and religious practices. The northern regions included Bithynia, Paphlagonia, and Pontus; to the west were Mysia, Lydia, and Caria; and Lycia, Pamphylia, and Cilicia belonged to the southern shore. There were also several inland regions: Phrygia, Cappadocia, Pisidia, and Galatia. Languages spoken included the late surviving Anatolic languages, Isaurian, and Pisidian, Greek in western and coastal regions, Phrygian spoken until the 7th century CE, local variants of Thracian in the northwest, the Galatian variant of Gaulish in Galatia until the 6th century CE, Cappadocian in the homonymous region, Armenian in the east, and Kartvelian languages in the northeast. Anatolia is known as the birthplace of minted coinage (as opposed to unminted coinage, which first appears in Mesopotamia at a much earlier date) as a medium of exchange, some time in the 7th century BCE in Lydia. The use of minted coins continued to flourish during the Greek and Roman eras. During the 6th century BCE, all of Anatolia was conquered by the Persian Achaemenid Empire, the Persians having usurped the Medes as the dominant dynasty of Persia. In 499 BCE, the Ionian city-states on the west coast of Anatolia rebelled against Persian rule. The Ionian Revolt, as it became known, though quelled, initiated the Greco-Persian Wars, which ended in a Greek victory in 449 BCE, and the Ionian cities regained their independence. By the Peace of Antalcidas (387 BCE), which ended the Corinthian War, Persia regained control over Ionia. In 334 BCE, the Macedonian Greek king Alexander the Great conquered the Anatolian peninsula from the Achaemenid Persian Empire. Alexander's conquest opened up the interior of Asia Minor to Greek settlement and influence. Following the death of Alexander the Great and the subsequent breakup of the Macedonian Empire, Anatolia was ruled by a series of Hellenistic kingdoms, such as the Attalids of Pergamum and the Seleucids, the latter controlling most of Anatolia. A period of peaceful Hellenization followed, such that the local Anatolian languages had been supplanted by Greek by the 1st century BCE. In 133 BCE the last Attalid king bequeathed his kingdom to the Roman Republic; western and central Anatolia came under Roman control, but Hellenistic culture remained predominant. Mithridates VI Eupator, ruler of the Kingdom of Pontus in northern Anatolia, waged war against the Roman Republic in the year 88 BCE in order to halt the advance of Roman hegemony in the Aegean Sea region. Mithridates VI sought to dominate Asia Minor and the Black Sea region, waging several hard-fought but ultimately unsuccessful wars (the Mithridatic Wars) to break Roman dominion over Asia and the Hellenic world. He has been called the greatest ruler of the Kingdom of Pontus. Further annexations by Rome, in particular of the Kingdom of Pontus by Pompey, brought all of Anatolia under Roman control, except for the southeastern frontier with the Parthian Empire, which remained unstable for centuries, causing a series of military conflicts that culminated in the Roman–Parthian Wars (54 BCE – 217 CE). Early Christian Period After the first division of the Roman Empire, Anatolia became part of the Eastern Roman Empire, otherwise known as the Byzantine Empire or Byzantium. In the 1st century CE, Anatolia became one of the first places where Christianity spread, so that by the 4th century CE, western and central Anatolia were overwhelmingly Christian and Greek-speaking. Byzantine Anatolia was one of the wealthiest and most densely populated places in the Later Roman Empire. Anatolia's wealth grew during the 4th and 5th centuries thanks, in part, to the Pilgrim's Road that ran through the peninsula. Literary evidence about the rural landscape stems from the Christian hagiographies of the 6th-century Nicholas of Sion and 7th-century Theodore of Sykeon. Large and prosperous urban centers of Byzantine Anatolia included Assos, Ephesus, Miletus, Nicaea, Pergamum, Priene, Sardis, and Aphrodisias. From the mid-5th century onwards, urbanism was affected negatively and began to decline, while the rural areas reached unprecedented levels of prosperity in the region. Historians and scholars continue to debate the cause of the urban decline in Byzantine Anatolia between the 6th and 7th centuries, variously attributing it to the Plague of Justinian (541), the Byzantine–Sasanian War (602–628), and the Arab invasion of the Levant (634–638). Medieval Period In the 10 years following the Battle of Manzikert in 1071, the Seljuk Turks from Central Asia migrated over large areas of Anatolia, with particular concentrations around the northwestern rim. The Turkish language and the Islamic religion were gradually introduced as a result of the Seljuk conquest, and this period marks the start of Anatolia's slow transition from predominantly Christian and Greek-speaking, to predominantly Muslim and Turkish-speaking (although ethnic groups such as Armenians, Greeks, and Assyrians remained numerous and retained Christianity and their native languages). In the following century, the Byzantines managed to reassert their control in western and northern Anatolia. Control of Anatolia was then split between the Byzantine Empire and the Seljuk Sultanate of Rûm, with the Byzantine holdings gradually being reduced. In 1255, the Mongols swept through eastern and central Anatolia, and would remain until 1335. The Ilkhanate garrison was stationed near Ankara. After the decline of the Ilkhanate from 1335 to 1353, the Mongol Empire's legacy in the region was the Uyghur Eretna Dynasty that was overthrown by Kadi Burhan al-Din in 1381. By the end of the 14th century, most of Anatolia was controlled by various Anatolian beyliks. Smyrna fell in 1330, and the last Byzantine stronghold in Anatolia, Philadelphia, fell in 1390. The Turkmen Beyliks were under the control of the Mongols, at least nominally, through declining Seljuk sultans. The Beyliks did not mint coins in the names of their own leaders while they remained under the suzerainty of the Mongol Ilkhanids. The Osmanli ruler Osman I was the first Turkish ruler who minted coins in his own name in 1320s; they bear the legend "Minted by Osman son of Ertugrul". Since the minting of coins was a prerogative accorded in Islamic practice only to a sovereign, it can be considered that the Osmanli, or Ottoman Turks, had become formally independent from the Mongol Khans. Ottoman Empire Among the Turkish leaders, the Ottomans emerged as great power under Osman I and his son Orhan I. The Anatolian beyliks were successively absorbed into the rising Ottoman Empire during the 15th century. It is not well understood how the Osmanlı, or Ottoman Turks, came to dominate their neighbours, as the history of medieval Anatolia is still little known. The Ottomans completed the conquest of the peninsula in 1517 with the taking of Halicarnassus (modern Bodrum) from the Knights of Saint John. Modern times With the acceleration of the decline of the Ottoman Empire in the early 19th century, and as a result of the expansionist policies of the Russian Empire in the Caucasus, many Muslim nations and groups in that region, mainly Circassians, Tatars, Azeris, Lezgis, Chechens and several Turkic groups left their homelands and settled in Anatolia. As the Ottoman Empire further shrank in the Balkan regions and then fragmented during the Balkan Wars, much of the non-Christian populations of its former possessions, mainly Balkan Muslims (Bosnian Muslims, Albanians, Turks, Muslim Bulgarians and Greek Muslims such as the Vallahades from Greek Macedonia), were resettled in various parts of Anatolia, mostly in formerly Christian villages throughout Anatolia. A continuous reverse migration occurred since the early 19th century, when Greeks from Anatolia, Constantinople and Pontus area migrated toward the newly independent Kingdom of Greece, and also towards the United States, the southern part of the Russian Empire, Latin America, and the rest of Europe. Following the Russo-Persian Treaty of Turkmenchay (1828) and the incorporation of Eastern Armenia into the Russian Empire, another migration involved the large Armenian population of Anatolia, which recorded significant migration rates from Western Armenia (Eastern Anatolia) toward the Russian Empire, especially toward its newly established Armenian provinces. Anatolia remained multi-ethnic until the early 20th century (see the rise of nationalism under the Ottoman Empire). During World War I, the Armenian genocide, the Greek genocide (especially in Pontus), and the Assyrian genocide almost entirely removed the ancient indigenous communities of Armenian, Greek, and Assyrian populations in Anatolia and surrounding regions. Following the Greco-Turkish War of 1919–1922, most remaining ethnic Anatolian Greeks were forced out during the 1923 population exchange between Greece and Turkey. Of the remainder, most have left Turkey since then, leaving fewer than 5,000 Greeks in Anatolia today. Geology Anatolia's terrain is structurally complex. A central massif composed of uplifted blocks and downfolded troughs, covered by recent deposits and giving the appearance of a plateau with rough terrain, is wedged between two folded mountain ranges that converge in the east. True lowland is confined to a few narrow coastal strips along the Aegean, Mediterranean, and the Black Sea coasts. Flat or gently sloping land is rare and largely confined to the deltas of the Kızıl River, the coastal plains of Çukurova and the valley floors of the Gediz River and the Büyük Menderes River as well as some interior high plains in Anatolia, mainly around Lake Tuz (Salt Lake) and the Konya Basin (Konya Ovasi). There are two mountain ranges in southern Anatolia: the Taurus and the Zagros mountains. Climate Anatolia has a varied range of climates. The central plateau is characterized by a continental climate, with hot summers and cold snowy winters. The south and west coasts enjoy a typical Mediterranean climate, with mild rainy winters, and warm dry summers. The Black Sea and Marmara coasts have a temperate oceanic climate, with cool foggy summers and much rainfall throughout the year. Ecoregions There is a diverse number of plant and animal communities. The mountains and coastal plain of northern Anatolia experience a humid and mild climate. There are temperate broadleaf, mixed and coniferous forests. The central and eastern plateau, with its drier continental climate, has deciduous forests and forest steppes. Western and southern Anatolia, which have a Mediterranean climate, contain Mediterranean forests, woodlands, and scrub ecoregions. Euxine-Colchic deciduous forests: These temperate broadleaf and mixed forests extend across northern Anatolia, lying between the mountains of northern Anatolia and the Black Sea. They include the enclaves of temperate rainforest lying along the southeastern coast of the Black Sea in eastern Turkey and Georgia. Northern Anatolian conifer and deciduous forests: These forests occupy the mountains of northern Anatolia, running east and west between the coastal Euxine-Colchic forests and the drier, continental climate forests of central and eastern Anatolia. Central Anatolian deciduous forests: These forests of deciduous oaks and evergreen pines cover the plateau of central Anatolia. Central Anatolian steppe: These dry grasslands cover the drier valleys and surround the saline lakes of central Anatolia, and include halophytic (salt tolerant) plant communities. Eastern Anatolian deciduous forests: This ecoregion occupies the plateau of eastern Anatolia. The drier and more continental climate is beneficial for steppe-forests dominated by deciduous oaks, with areas of shrubland, montane forest, and valley forest. Anatolian conifer and deciduous mixed forests: These forests occupy the western, Mediterranean-climate portion of the Anatolian plateau. Pine forests and mixed pine and oak woodlands and shrublands are predominant. Aegean and Western Turkey sclerophyllous and mixed forests: These Mediterranean-climate forests occupy the coastal lowlands and valleys of western Anatolia bordering the Aegean Sea. The ecoregion has forests of Turkish pine (Pinus brutia), oak forests and woodlands, and maquis shrubland of Turkish pine and evergreen sclerophyllous trees and shrubs, including Olive (Olea europaea), Strawberry Tree (Arbutus unedo), Arbutus andrachne, Kermes Oak (Quercus coccifera), and Bay Laurel (Laurus nobilis). Southern Anatolian montane conifer and deciduous forests: These mountain forests occupy the Mediterranean-climate Taurus Mountains of southern Anatolia. Conifer forests are predominant, chiefly Anatolian black pine (Pinus nigra), Cedar of Lebanon (Cedrus libani), Taurus fir (Abies cilicica), and juniper (Juniperus foetidissima and J. excelsa). Broadleaf trees include oaks, hornbeam, and maples. Eastern Mediterranean conifer-sclerophyllous-broadleaf forests: This ecoregion occupies the coastal strip of southern Anatolia between the Taurus Mountains and the Mediterranean Sea. Plant communities include broadleaf sclerophyllous maquis shrublands, forests of Aleppo Pine (Pinus halepensis) and Turkish Pine (Pinus brutia), and dry oak (Quercus spp.) woodlands and steppes. Demographics The largest cities in Anatolia (aside from Ankara) are İzmir, Bursa, Antalya, Konya, Adana, İzmit, Mersin, Manisa, Kayseri, Samsun, Balıkesir, Kahramanmaraş, Aydın, Adapazarı, Denizli, Muğla, Eskişehir, Trabzon, Ordu, Afyonkarahisar, Sivas, Tokat, Zonguldak, Kütahya, Çanakkale, Osmaniye, Şırnak and Çorum. All have populations of more than 500,000.

Apple Inc.

Apple Inc. is an American multinational technology company headquartered in Cupertino, California, United States. Apple is the largest technology company by revenue (totaling in 2021) and, , is the world's biggest company by market capitalization, the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet (Google), Amazon, Meta (Facebook), and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977 and the company's next computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user interfaces, including the 1984 original Macintosh, announced that year in a critically acclaimed advertisement. By 1985, the high cost of its products and power struggles between executives caused problems. Wozniak stepped back from Apple amicably and pursued other ventures, while Jobs resigned bitterly and founded NeXT, taking some Apple employees with him. As the market for personal computers expanded and evolved throughout the 1990s, Apple lost considerable market share to the lower-priced duopoly of the Microsoft Windows operating system on Intel-powered PC clones (also known as "Wintel"). In 1997, weeks away from bankruptcy, the company bought NeXT to resolve Apple's unsuccessful operating system strategy and entice Jobs back to the company. Over the next decade, Jobs guided Apple back to profitability through a number of tactics including introducing the iMac, iPod, iPhone and iPad to critical acclaim, launching "Think different" and other memorable advertising campaigns, opening the Apple Store retail chain, and acquiring numerous companies to broaden the company's product portfolio. When Jobs resigned in 2011 for health reasons, and died two months later, he was succeeded as CEO by Tim Cook. Apple became the first publicly traded U.S. company to be valued at over $1 trillion in August 2018, then $2 trillion in August 2020, and $3 trillion in January 2022. , it was valued at around $2.2 trillion. The company receives criticism regarding the labor practices of its contractors, its environmental practices, and its business ethics, including anti-competitive practices and materials sourcing. Nevertheless, the company has a large following and enjoys a high level of brand loyalty. It is ranked as one of the world's most valuable brands. History 1976–1980: Founding and incorporation Apple Computer Company was founded on April 1, 1976, by Steve Jobs, Steve Wozniak, and Ronald Wayne as a partnership. The company's first product was the Apple I, a computer designed and hand-built entirely by Wozniak. To finance its creation, Jobs sold his Volkswagen Bus, and Wozniak sold his HP-65 calculator. Wozniak debuted the first prototype Apple I at the Homebrew Computer Club in July 1976. The Apple I was sold as a motherboard with CPU, RAM, and basic textual-video chips—a base kit concept which would not yet be marketed as a complete personal computer. It went on sale soon after debut for . Wozniak later said he was unaware of the coincidental mark of the beast in the number 666, and that he came up with the price because he liked "repeating digits". Apple Computer, Inc. was incorporated on January 3, 1977, without Wayne, who had left and sold his share of the company back to Jobs and Wozniak for $800 only twelve days after having co-founded Apple. Multimillionaire Mike Markkula provided essential business expertise and funding of to Jobs and Wozniak during the incorporation of Apple. During the first five years of operations, revenues grew exponentially, doubling about every four months. Between September 1977 and September 1980, yearly sales grew from $775,000 to $118 million, an average annual growth rate of 533%. The Apple II, also invented by Wozniak, was introduced on April 16, 1977, at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 and Commodore PET, because of its character cell-based color graphics and open architecture. While the Apple I and early Apple II models used ordinary audio cassette tapes as storage devices, they were superseded by the introduction of a -inch floppy disk drive and interface called the Disk II in 1978. The Apple II was chosen to be the desktop platform for the first "killer application" of the business world: VisiCalc, a spreadsheet program released in 1979. VisiCalc created a business market for the Apple II and gave home users an additional reason to buy an Apple II: compatibility with the office. Before VisiCalc, Apple had been a distant third place competitor to Commodore and Tandy. By the end of the 1970s, Apple had become the leading computer manufacturer in the United States. On December 12, 1980, Apple (ticker symbol "AAPL") went public selling 4.6 million shares at $22 per share ($.10 per share when adjusting for stock splits ), generating over $100 million, which was more capital than any IPO since Ford Motor Company in 1956. By the end of the day, 300 millionaires were created, from a stock price of $29 per share and a market cap of $1.778 billion. 1980–1990: Success with Macintosh A critical moment in the company's history came in December 1979 when Jobs and several Apple employees, including human–computer interface expert Jef Raskin, visited Xerox PARC in to see a demonstration of the Xerox Alto, a computer using a graphical user interface. Xerox granted Apple engineers three days of access to the PARC facilities in return for the option to buy 100,000 shares (22.4 million split-adjusted shares ) of Apple at the pre-IPO price of $10 a share. After the demonstration, Jobs was immediately convinced that all future computers would use a graphical user interface, and development of a GUI began for the Apple Lisa, named after Jobs's daughter. The Lisa division would be plagued by infighting, and in 1982 Jobs was pushed off the project. The Lisa launched in 1983 and became the first personal computer sold to the public with a GUI, but was a commercial failure due to its high price and limited software titles. Jobs, angered by being pushed off the Lisa team, took over the company's Macintosh division. Wozniak and Raskin had envisioned the Macintosh as a low-cost computer with a text-based interface like the Apple II, but a plane crash in 1981 forced Wozniak to step back from the project. Jobs quickly redefined the Macintosh as a graphical system that would be cheaper than the Lisa, undercutting his former division. Jobs was also hostile to the Apple II division, which at the time, generated most of the company's revenue. In 1984, Apple launched the Macintosh, the first personal computer to be sold without a programming language. Its debut was signified by "1984", a $1.5 million television advertisement directed by Ridley Scott that aired during the third quarter of Super Bowl XVIII on January 22, 1984. This is now hailed as a watershed event for Apple's success and was called a "masterpiece" by CNN and one of the greatest TV advertisements of all time by TV Guide. The advertisement created great interest in the original Macintosh, and sales were initially good, but began to taper off dramatically after the first three months as reviews started to come in. Jobs had made the decision to equip the original Macintosh with 128 kilobytes of RAM, attempting to reach a price point, which limited its speed and the software that could be used. The Macintosh would eventually ship for , a price panned by critics in light of its slow performance. In early 1985, this sales slump triggered a power struggle between Steve Jobs and CEO John Sculley, who had been hired away from Pepsi two years earlier by Jobs saying, "Do you want to sell sugar water for the rest of your life or come with me and change the world?" Sculley decided to remove Jobs as the head of the Macintosh division, with unanimous support from the Apple board of directors. The board of directors instructed Sculley to contain Jobs and his ability to launch expensive forays into untested products. Rather than submit to Sculley's direction, Jobs attempted to oust him from his leadership role at Apple. Informed by Jean-Louis Gassée, Sculley found out that Jobs had been attempting to organize a boardroom coup and called an emergency meeting at which Apple's executive staff sided with Sculley and stripped Jobs of all operational duties. Jobs resigned from Apple in September 1985 and took a number of Apple employees with him to found NeXT. Wozniak had also quit his active employment at Apple earlier in 1985 to pursue other ventures, expressing his frustration with Apple's treatment of the Apple II division and stating that the company had "been going in the wrong direction for the last five years." Despite Wozniak's grievances, he officially remained employed by Apple, and to this day continues to work for the company as a representative, receiving a stipend estimated to be $120,000 per year for this role. Both Jobs and Wozniak remained Apple shareholders after their departures. After the departures of Jobs and Wozniak, Sculley worked to improve the Macintosh in 1985 by quadrupling the RAM and introducing the LaserWriter, the first reasonably priced PostScript laser printer. PageMaker, an early desktop publishing application taking advantage of the PostScript language, was also released by Aldus Corporation in July 1985. It has been suggested that the combination of Macintosh, LaserWriter and PageMaker was responsible for the creation of the desktop publishing market. This dominant position in the desktop publishing market allowed the company to focus on higher price points, the so-called "high-right policy" named for the position on a chart of price vs. profits. Newer models selling at higher price points offered higher profit margin, and appeared to have no effect on total sales as power users snapped up every increase in speed. Although some worried about pricing themselves out of the market, the high-right policy was in full force by the mid-1980s, notably due to Jean-Louis Gassée's mantra of "fifty-five or die", referring to the 55% profit margins of the Macintosh II. This policy began to backfire in the last years of the decade as desktop publishing programs appeared on PC clones that offered some or much of the same functionality of the Macintosh, but at far lower price points. The company lost its dominant position in the desktop publishing market and estranged many of its original consumer customer base who could no longer afford their high-priced products. The Christmas season of 1989 was the first in the company's history to have declining sales, which led to a 20% drop in Apple's stock price. During this period, the relationship between Sculley and Gassée deteriorated, leading Sculley to effectively demote Gassée in January 1990 by appointing Michael Spindler as the chief operating officer. Gassée left the company later that year. 1990–1997: Decline and restructuring The company pivoted strategy and in October 1990 introduced three lower-cost models, the Macintosh Classic, the Macintosh LC, and the Macintosh IIsi, all of which saw significant sales due to pent-up demand. In 1991, Apple introduced the hugely successful PowerBook with a design that set the current shape for almost all modern laptops. The same year, Apple introduced System 7, a major upgrade to the Macintosh operating system, adding color to the interface and introducing new networking capabilities. The success of the lower-cost Macs and PowerBook brought increasing revenue. For some time, Apple was doing incredibly well, introducing fresh new products and generating increasing profits in the process. The magazine MacAddict named the period between 1989 and 1991 as the "first golden age" of the Macintosh. The success of Apple's lower-cost consumer models, especially the LC, also led to the cannibalization of their higher-priced machines. To address this, management introduced several new brands, selling largely identical machines at different price points, aimed at different markets: the high-end Quadra models, the mid-range Centris line, and the consumer-marketed Performa series. This led to significant market confusion, as customers did not understand the difference between models. The early 1990s also saw the discontinuation of the Apple II series, which was expensive to produce, and the company felt was still taking sales away from lower-cost Macintosh models. After the launch of the LC, Apple began encouraging developers to create applications for Macintosh rather than Apple II, and authorized salespersons to direct consumers towards Macintosh and away from Apple II. The Apple IIe was discontinued in 1993. Throughout this period, Microsoft continued to gain market share with its Windows graphical user interface that it sold to manufacturers of generally less expensive PC clones. While the Macintosh was more expensive, it offered a more tightly integrated user experience, but the company struggled to make the case to consumers. Apple also experimented with a number of other unsuccessful consumer targeted products during the 1990s, including digital cameras, portable CD audio players, speakers, video game consoles, the eWorld online service, and TV appliances. Most notably, enormous resources were invested in the problem-plagued Newton tablet division, based on John Sculley's unrealistic market forecasts. Throughout this period, Microsoft continued to gain market share with Windows by focusing on delivering software to inexpensive personal computers, while Apple was delivering a richly engineered but expensive experience. Apple relied on high profit margins and never developed a clear response; instead, they sued Microsoft for using a GUI similar to the Apple Lisa in Apple Computer, Inc. v. Microsoft Corp. The lawsuit dragged on for years before it was finally dismissed. The major product flops and the rapid loss of market share to Windows sullied Apple's reputation, and in 1993 Sculley was replaced as CEO by Michael Spindler. With Spindler at the helm, Apple, IBM, and Motorola formed the AIM alliance in 1994 with the goal of creating a new computing platform (the PowerPC Reference Platform; PReP), which would use IBM and Motorola hardware coupled with Apple software. The AIM alliance hoped that PReP's performance and Apple's software would leave the PC far behind and thus counter the dominance of Windows. The same year, Apple introduced the Power Macintosh, the first of many Apple computers to use Motorola's PowerPC processor. In the wake of the alliance, Apple opened up to the idea of allowing Motorola and other companies to build Macintosh clones. Over the next two years, 75 distinct Macintosh clone models were introduced. However, by 1996, Apple executives were worried that the clones were cannibalizing sales of their own high-end computers, where profit margins were highest. In 1996, Spindler was replaced by Gil Amelio as CEO. Hired for his reputation as a corporate rehabilitator, Amelio made deep changes, including extensive layoffs and cost-cutting. This period was also marked by numerous failed attempts to modernize the Macintosh operating system (MacOS). The original Macintosh operating system (System 1) was not built for multitasking (running several applications at once). The company attempted to correct this with by introducing cooperative multitasking in System 5, but the company still felt it needed a more modern approach. This led to the Pink project in 1988, A/UX that same year, Copland in 1994, and the attempted purchase of BeOS in 1996. Talks with Be stalled when the CEO, former Apple executive Jean-Louis Gassée, demanded $300 million instead of the $125 million Apple wanted to pay. Only weeks away from bankruptcy, Apple's board decided NeXTSTEP was a better choice for its next operating system and purchased NeXT in late 1996 for $400 million, bringing back Apple co-founder Steve Jobs. 1997–2007: Return to profitability The NeXT acquisition was finalized on February 9, 1997, and the board brought Jobs back to Apple as an advisor. On July 9, 1997, Jobs staged a boardroom coup that resulted in Amelio's resignation after overseeing a three-year record-low stock price and crippling financial losses. The board named Jobs as interim CEO and he immediately began a review of the company's products. Jobs would order 70% of the company's products to be cancelled, resulting in the loss of 3,000 jobs, and taking Apple back to the core of its computer offerings. The next month, in August 1997, Steve Jobs convinced Microsoft to make a $150 million investment in Apple and a commitment to continue developing software for the Mac. The investment was seen as an "antitrust insurance policy" for Microsoft who had recently settled with the Department of Justice over anti-competitive practices. Jobs also ended the Mac clone deals and in September 1997, purchased the largest clone maker, Power Computing. On November 10, 1997, Apple introduced the Apple Store website, which was tied to a new build-to-order manufacturing that had been successfully used by PC manufacturer Dell. The moves paid off for Jobs, at the end of his first year as CEO, the company turned a $309 million profit. On May 6, 1998, Apple introduced a new all-in-one computer reminiscent of the original Macintosh: the iMac. The iMac was a huge success for Apple selling 800,000 units in its first five months and ushered in major shifts in the industry by abandoning legacy technologies like the -inch diskette, being an early adopter of the USB connector, and coming pre-installed with internet connectivity (the "i" in iMac) via Ethernet and a dial-up modem. The device also had a striking teardrop shape and translucent materials, designed by Jonathan Ive, who although hired by Amelio, would go on to work collaboratively with Jobs for the next decade to chart a new course the design of Apple's products. A little more than a year later on July 21, 1999, Apple introduced the iBook, a laptop for consumers. It was the culmination of a strategy established by Jobs to produce only four products: refined versions of the Power Macintosh G3 desktop and PowerBook G3 laptop for professionals, along with the iMac desktop and iBook laptop for consumers. Jobs felt the small product line allowed for a greater focus on quality and innovation. At around the same time, Apple also completed numerous acquisitions to create a portfolio of digital media production software for both professionals and consumers. Apple acquired of Macromedia's Key Grip digital video editing software project which was renamed Final Cut Pro when it was launched on the retail market in April 1999. The development of Key Grip also led to Apple's release of the consumer video-editing product iMovie in October 1999. Next, Apple successfully acquired the German company Astarte in April 2000, which had developed the DVD authoring software DVDirector, which Apple would sell as the professional-oriented DVD Studio Pro software product, and used the same technology to create iDVD for the consumer market. In 2000, Apple purchased the SoundJam MP audio player software from Casady & Greene. Apple renamed the program iTunes, while simplifying the user interface and adding the ability to burn CDs. 2001 would be a pivotal year for the Apple with the company making three announcements that would change the course of the company. The first announcement came on March 24, 2001, that Apple was nearly ready to release a new modern operating system, Mac OS X. The announcement came after numerous failed attempts in the early 1990s, and several years of development. Mac OS X was based on NeXTSTEP, OPENSTEP, and BSD Unix, with Apple aiming to combine the stability, reliability, and security of Unix with the ease of use afforded by an overhauled user interface, heavily influenced by NeXTSTEP. To aid users in migrating from Mac OS 9, the new operating system allowed the use of OS 9 applications within Mac OS X via the Classic Environment. In May 2001, the company opened its first two Apple Store retail locations in Virginia and California, offering an improved presentation of the company's products. At the time, many speculated that the stores would fail, but they went on to become highly successful, and the first of more than 500 stores around the world. On October 23, 2001, Apple debuted the iPod portable digital audio player. The product, which was first sold on November 10, 2001, was phenomenally successful with over 100 million units sold within six years. In 2003, Apple's iTunes Store was introduced. The service offered music downloads for 99¢ a song and integration with the iPod. The iTunes Store quickly became the market leader in online music services, with over five billion downloads by June 19, 2008. Two years later, the iTunes Store was the world's largest music retailer. In 2002, Apple purchased Nothing Real for their advanced digital compositing application Shake, as well as Emagic for the music productivity application Logic. The purchase of Emagic made Apple the first computer manufacturer to own a music software company. The acquisition was followed by the development of Apple's consumer-level GarageBand application. The release of iPhoto in the same year completed the iLife suite. At the Worldwide Developers Conference keynote address on June 6, 2005, Jobs announced that Apple would move away from PowerPC processors, and the Mac would transition to Intel processors in 2006. On January 10, 2006, the new MacBook Pro and iMac became the first Apple computers to use Intel's Core Duo CPU. By August 7, 2006, Apple made the transition to Intel chips for the entire Mac product line—over one year sooner than announced. The Power Mac, iBook, and PowerBook brands were retired during the transition; the Mac Pro, MacBook, and MacBook Pro became their respective successors. On April 29, 2009, The Wall Street Journal reported that Apple was building its own team of engineers to design microchips. Apple also introduced Boot Camp in 2006 to help users install Windows XP or Windows Vista on their Intel Macs alongside Mac OS X. Apple's success during this period was evident in its stock price. Between early 2003 and 2006, the price of Apple's stock increased more than tenfold, from around $6 per share (split-adjusted) to over $80. When Apple surpassed Dell's market cap in January 2006, Jobs sent an email to Apple employees saying Dell's CEO Michael Dell should eat his words. Nine years prior, Dell had said that if he ran Apple he would "shut it down and give the money back to the shareholders". 2007–2011: Success with mobile devices During his keynote speech at the Macworld Expo on January 9, 2007, Jobs announced that Apple Computer, Inc. would thereafter be known as "Apple Inc.", because the company had shifted its emphasis from computers to consumer electronics. This event also saw the announcement of the iPhone and the Apple TV. The company sold 270,000 iPhone units during the first 30 hours of sales, and the device was called "a game changer for the industry". In an article posted on Apple's website on February 6, 2007, Jobs wrote that Apple would be willing to sell music on the iTunes Store without digital rights management (DRM), thereby allowing tracks to be played on third-party players, if record labels would agree to drop the technology. On April 2, 2007, Apple and EMI jointly announced the removal of DRM technology from EMI's catalog in the iTunes Store, effective in May 2007. Other record labels eventually followed suit and Apple published a press release in January 2009 to announce that all songs on the iTunes Store are available without their FairPlay DRM. In July 2008, Apple launched the App Store to sell third-party applications for the iPhone and iPod Touch. Within a month, the store sold 60 million applications and registered an average daily revenue of $1 million, with Jobs speculating in August 2008 that the App Store could become a billion-dollar business for Apple. By October 2008, Apple was the third-largest mobile handset supplier in the world due to the popularity of the iPhone. On January 14, 2009, Jobs announced in an internal memo that he would be taking a six-month medical leave of absence from Apple until the end of June 2009 and would spend the time focusing on his health. In the email, Jobs stated that "the curiosity over my personal health continues to be a distraction not only for me and my family, but everyone else at Apple as well", and explained that the break would allow the company "to focus on delivering extraordinary products". Though Jobs was absent, Apple recorded its best non-holiday quarter (Q1 FY 2009) during the recession with revenue of $8.16 billion and profit of $1.21 billion. After years of speculation and multiple rumored "leaks", Apple unveiled a large screen, tablet-like media device known as the iPad on January 27, 2010. The iPad ran the same touch-based operating system as the iPhone, and all iPhone apps were compatible with the iPad. This gave the iPad a large app catalog on launch, though having very little development time before the release. Later that year on April 3, 2010, the iPad was launched in the U.S. It sold more than 300,000 units on its first day, and 500,000 by the end of the first week. In May of the same year, Apple's market cap exceeded that of competitor Microsoft for the first time since 1989. In June 2010, Apple released the iPhone 4, which introduced video calling using FaceTime, multitasking, and a new uninsulated stainless steel design that acted as the phone's antenna. Later that year, Apple again refreshed its iPod line of MP3 players by introducing a multi-touch iPod Nano, an iPod Touch with FaceTime, and an iPod Shuffle that brought back the clickwheel buttons of earlier generations. It also introduced the smaller, cheaper second generation Apple TV which allowed renting of movies and shows. On January 17, 2011, Jobs announced in an internal Apple memo that he would take another medical leave of absence for an indefinite period to allow him to focus on his health. Chief operating officer Tim Cook assumed Jobs's day-to-day operations at Apple, although Jobs would still remain "involved in major strategic decisions". Apple became the most valuable consumer-facing brand in the world. In June 2011, Jobs surprisingly took the stage and unveiled iCloud, an online storage and syncing service for music, photos, files, and software which replaced MobileMe, Apple's previous attempt at content syncing. This would be the last product launch Jobs would attend before his death. On August 24, 2011, Jobs resigned his position as CEO of Apple. He was replaced by Cook and Jobs became Apple's chairman. Apple did not have a chairman at the time and instead had two co-lead directors, Andrea Jung and Arthur D. Levinson, who continued with those titles until Levinson replaced Jobs as chairman of the board in November after Jobs' death. 2011–present: Post-Jobs era, Cook's leadership On October 5, 2011, Steve Jobs died, marking the end of an era for Apple. The first major product announcement by Apple following Jobs's passing occurred on January 19, 2012, when Apple's Phil Schiller introduced iBook's Textbooks for iOS and iBook Author for Mac OS X in New York City. Jobs stated in the biography "Jobs" that he wanted to reinvent the textbook industry and education. From 2011 to 2012, Apple released the iPhone 4S and iPhone 5, which featured improved cameras, an intelligent software assistant named Siri, and cloud-synced data with iCloud; the third- and fourth-generation iPads, which featured Retina displays; and the iPad Mini, which featured a 7.9-inch screen in contrast to the iPad's 9.7-inch screen. These launches were successful, with the iPhone 5 (released September 21, 2012) becoming Apple's biggest iPhone launch with over two million pre-orders and sales of three million iPads in three days following the launch of the iPad Mini and fourth-generation iPad (released November 3, 2012). Apple also released a third-generation 13-inch MacBook Pro with a Retina display and new iMac and Mac Mini computers. On August 20, 2012, Apple's rising stock price increased the company's market capitalization to a then-record $624 billion. This beat the non-inflation-adjusted record for market capitalization previously set by Microsoft in 1999. On August 24, 2012, a US jury ruled that Samsung should pay Apple $1.05 billion (£665m) in damages in an intellectual property lawsuit. Samsung appealed the damages award, which was reduced by $450 million and further granted Samsung's request for a new trial. On November 10, 2012, Apple confirmed a global settlement that dismissed all existing lawsuits between Apple and HTC up to that date, in favor of a ten-year license agreement for current and future patents between the two companies. It is predicted that Apple will make $280 million a year from this deal with HTC. In May 2014, the company confirmed its intent to acquire Dr. Dre and Jimmy Iovine's audio company Beats Electronics—producer of the "Beats by Dr. Dre" line of headphones and speaker products, and operator of the music streaming service Beats Music—for $3 billion, and to sell their products through Apple's retail outlets and resellers. Iovine believed that Beats had always "belonged" with Apple, as the company modeled itself after Apple's "unmatched ability to marry culture and technology." The acquisition was the largest purchase in Apple's history. During a press event on September 9, 2014, Apple introduced a smartwatch, the Apple Watch. Initially, Apple marketed the device as a fashion accessory and a complement to the iPhone, that would allow people to look at their smartphones less. Over time, the company has focused on developing health and fitness-oriented features on the watch, in an effort to compete with dedicated activity trackers. In January 2016, it was announced that one billion Apple devices were in active use worldwide. On June 6, 2016, Fortune released Fortune 500, their list of companies ranked on revenue generation. In the trailing fiscal year (2015), Apple appeared on the list as the top tech company. It ranked third, overall, with $233 billion in revenue. This represents a movement upward of two spots from the previous year's list. In June 2017, Apple announced the HomePod, its smart speaker aimed to compete against Sonos, Google Home, and Amazon Echo. Towards the end of the year, TechCrunch reported that Apple was acquiring Shazam, a company that introduced its products at WWDC and specializing in music, TV, film and advertising recognition. The acquisition was confirmed a few days later, reportedly costing Apple $400 million, with media reports noting that the purchase looked like a move to acquire data and tools bolstering the Apple Music streaming service. The purchase was approved by the European Union in September 2018. Also in June 2017, Apple appointed Jamie Erlicht and Zack Van Amburg to head the newly formed worldwide video unit. In November 2017, Apple announced it was branching out into original scripted programming: a drama series starring Jennifer Aniston and Reese Witherspoon, and a reboot of the anthology series Amazing Stories with Steven Spielberg. In June 2018, Apple signed the Writers Guild of America's minimum basic agreement and Oprah Winfrey to a multi-year content partnership. Additional partnerships for original series include Sesame Workshop and DHX Media and its subsidiary Peanuts Worldwide, as well as a partnership with A24 to create original films. During the Apple Special Event in September 2017, the AirPower wireless charger was announced alongside the iPhone X, 8 and Watch Series 3. The AirPower was intended to wirelessly charge multiple devices, simultaneously. Though initially set to release in early 2018, the AirPower would be canceled in March 2019, marking the first cancellation of a device under Cook's leadership. On August 19, 2020, Apple's share price briefly topped $467.77, making Apple the first US company with a market capitalization of $2 trillion. During its annual WWDC keynote speech on June 22, 2020, Apple announced it would move away from Intel processors, and the Mac would transition to processors developed in-house. The announcement was expected by industry analysts, and it has been noted that Macs featuring Apple's processors would allow for big increases in performance over current Intel-based models. On November 10, 2020, the MacBook Air, MacBook Pro, and the Mac Mini became the first Mac devices powered by an Apple-designed processor, the Apple M1. In April 2022, it was reported that Samsung Electro-Mechanics would be collaborating with Apple on its M2 chip instead of LG Innotek. Developer logs showed that at least nine Mac models with four different M2 chips were being tested. The Wall Street Journal reported that an effort to develop its own chips left Apple better prepared to deal with the semiconductor shortage that emerged during the pandemic era and led to increased profitability, with sales of Mac computers that included M1 chips rising sharply in 2020 and 2021. It also inspired other companies like Tesla, Amazon, and Meta Platforms to pursue a similar path. In April 2022, Apple opened an online store that allowed anyone in the US to view repair manuals and order replacement parts for specific recent iPhones, although the difference in cost between this method and official repair is anticipated to be minimal. In May 2022, a trademark was filed for RealityOS, an operating system reportedly intended for virtual and augmented reality headsets, first mentioned in 2017. According to Bloomberg, the headset may come out in 2023. Further insider reports state that the device uses iris scanning for payment confirmation and signing into accounts. On June 18, 2022, the Apple Store in Towson, Maryland became the first to unionize in the U.S., with the employees voting to join the International Association of Machinists and Aerospace Workers. On July 7, 2022, Apple added Lockdown Mode to macOS 13 and iOS 16, as a response to the earlier Pegasus revelations; the mode increases security protections for high-risk users against targeted zero-day malware. Products Mac The Mac is Apple's family of personal computers. Macs are known for their ease of use and distinctive aluminium, minimalist designs. Macs have been popular among students, creative professionals, and software engineers. The current lineup consists of the MacBook Air and MacBook Pro laptops, and the iMac, Mac mini, Mac Studio and Mac Pro desktop computers. All Macs except the Mac Pro use Apple silicon chips. Macs run the macOS operating system, and include the Safari web browser, iMovie for home movie editing, GarageBand for music creation, and the iWork productivity suite. Apple also makes pro apps: Final Cut Pro for video production, Logic Pro for musicians and producers, and Xcode for software developers. Apple also sells a variety of accessories for Macs, including the Pro Display XDR, Apple Studio Display, Magic Mouse, Magic Trackpad, and Magic Keyboard. iPhone The iPhone is Apple's line of smartphones, which run the iOS operating system. The first iPhone was unveiled by Steve Jobs on January 9, 2007. Since then, new models have been released annually. When it was introduced, its multi-touch screen was described as "revolutionary" and a "game-changer" for the mobile phone industry. The device has been credited with creating the app economy. As of 2022, the iPhone has 15% market share, yet represents 50% of global smartphone revenues, with Android phones accounting for the rest. The iPhone has generated large profits for the company, and is credited with helping to make Apple one of the world's most valuable publicly traded companies. The most recent iPhones are the iPhone 14, iPhone 14 Plus, iPhone 14 Pro and iPhone 14 Pro Max. iPad The iPad is Apple's line of tablets which run iPadOS. The first-generation iPad was announced on January 27, 2010. The iPad is mainly marketed for consuming multimedia, creating art, working on documents, videoconferencing, and playing games. The iPad lineup consists of several base iPad models, and the smaller iPad Mini, upgraded iPad Air, and high-end iPad Pro. Apple has consistently improved the iPad's performance, with the iPad Pro adopting the same M1 and M2 chips as the Mac; but the iPad still receives criticism for its limited OS. Apple has sold more than 500 million iPads, though sales peaked in 2013. The iPad still remains the most popular tablet computer by sales , and accounted for nine percent of the company's revenue . Apple sells several iPad accessories, including the Apple Pencil, Smart Keyboard, Smart Keyboard Folio, Magic Keyboard, and several adapters. Other products Apple also makes several other products that it categorizes as "Wearables, Home and Accessories". These products include the AirPods line of wireless headphones, Apple TV digital media players, Apple Watch smartwatches, Beats headphones and HomePod Mini smart speakers. , this broad line of products comprises about 11% of the company's revenues. Services Apple also offers a broad line of services that it earns revenue on, including advertising in the App Store and Apple News app, the AppleCare+ extended warranty plan, the iCloud+ cloud-based data storage service, payment services through the Apple Card credit card and the Apple Pay processing platform, a digital content services including Apple Books, Apple Fitness+, Apple Music, Apple News+, Apple TV+, and the iTunes Store. , services comprise about 19% of the company's revenue. Many of the services have been launched since 2019 when Apple announced it would be making a concerted effort to expand its service revenues. Marketing Branding According to Steve Jobs, the company's name was inspired by his visit to an apple farm while on a fruitarian diet. Jobs thought the name "Apple" was "fun, spirited and not intimidating." Steve Jobs and Steve Wozniak were fans of the Beatles, but Apple Inc. had name and logo trademark issues with Apple Corps Ltd., a multimedia company started by the Beatles in 1968. This resulted in a series of lawsuits and tension between the two companies. These issues ended with the settling of their lawsuit in 2007. Apple's first logo, designed by Ron Wayne, depicts Sir Isaac Newton sitting under an apple tree. It was almost immediately replaced by Rob Janoff's "rainbow Apple", the now-familiar rainbow-colored silhouette of an apple with a bite taken out of it. On August 27, 1999, Apple officially dropped the rainbow scheme and began to use monochromatic logos nearly identical in shape to the previous rainbow incarnation. Apple evangelists were actively engaged by the company at one time, but this was after the phenomenon had already been firmly established. Apple evangelist Guy Kawasaki has called the brand fanaticism "something that was stumbled upon," while Ive explained in 2014 that "people have an incredibly personal relationship" with Apple's products. Fortune magazine named Apple the most admired company in the United States in 2008, and in the world from 2008 to 2012. On September 30, 2013, Apple surpassed Coca-Cola to become the world's most valuable brand in the Omnicom Group's "Best Global Brands" report. Boston Consulting Group has ranked Apple as the world's most innovative brand every year since 2005. there are 1.65 billion Apple products in active use. Advertising Apple's first slogan, "Byte into an Apple", was coined in the late 1970s. From 1997 to 2002, the slogan "Think different" was used in advertising campaigns, and is still closely associated with Apple. Apple also has slogans for specific product lines—for example, "iThink, therefore iMac" was used in 1998 to promote the iMac, and "Say hello to iPhone" has been used in iPhone advertisements. "Hello" was also used to introduce the original Macintosh, Newton, iMac ("hello (again)"), and iPod. From the introduction of the Macintosh in 1984, with the 1984 Super Bowl advertisement to the more modern Get a Mac adverts, Apple has been recognized for its efforts towards effective advertising and marketing for its products. However, claims made by later campaigns were criticized, particularly the 2005 Power Mac ads. Apple's product advertisements gained a lot of attention as a result of their eye-popping graphics and catchy tunes. Musicians who benefited from an improved profile as a result of their songs being included on Apple advertisements include Canadian singer Feist with the song "1234" and Yael Naïm with the song "New Soul". Stores The first Apple Stores were originally opened as two locations in May 2001 by then-CEO Steve Jobs, after years of attempting but failing store-within-a-store concepts. Seeing a need for improved retail presentation of the company's products, he began an effort in 1997 to revamp the retail program to get an improved relationship to consumers, and hired Ron Johnson in 2000. Jobs relaunched Apple's online store in 1997, and opened the first two physical stores in 2001. The media initially speculated that Apple would fail, but its stores were highly successful, bypassing the sales numbers of competing nearby stores and within three years reached US$1 billion in annual sales, becoming the fastest retailer in history to do so. Over the years, Apple has expanded the number of retail locations and its geographical coverage, with 499 stores across 22 countries worldwide . Strong product sales have placed Apple among the top-tier retail stores, with sales over $16 billion globally in 2011. Apple Stores underwent a period of significant redesign, beginning in May 2016. This redesign included physical changes to the Apple Stores, such as open spaces and re-branded rooms, as well as changes in function to facilitate interaction between consumers and professionals. Many Apple Stores are located inside shopping malls, but Apple has built several stand-alone "flagship" stores in high-profile locations. It has been granted design patents and received architectural awards for its stores' designs and construction, specifically for its use of glass staircases and cubes. The success of Apple Stores have had significant influence over other consumer electronics retailers, who have lost traffic, control and profits due to a perceived higher quality of service and products at Apple Stores. Due to the popularity of the brand, Apple receives a large number of job applications, many of which come from young workers. Although Apple Store employees receive above-average pay, are offered money toward education and health care, and receive product discounts, there are limited or no paths of career advancement. Market power On March 16, 2020, France fined Apple €1.1 billion for colluding with two wholesalers to stifle competition and keep prices high by handicapping independent resellers. The arrangement created aligned prices for Apple products such as iPads and personal computers for about half the French retail market. According to the French regulators, the abuses occurred between 2005 and 2017 but were first discovered after a complaint by an independent reseller, eBizcuss, in 2012. On August 13, 2020, Epic Games, the maker of the popular game Fortnite, sued Apple and Google after its hugely popular video game was removed from Apple and Google's App Store. The suits come after both Apple and Google blocked the game after it introduced a direct payment system, effectively shutting out the tech titans from collecting fees. In September 2020 Epic Games founded the Coalition for App Fairness together with other thirteen companies, which aims for better conditions for the inclusion of apps in the app stores. Later in December 2020, Facebook agreed to assist Epic in their legal game against Apple, planning to support the company by providing materials and documents to Epic. Facebook had, however, stated that the company will not participate directly with the lawsuit, although did commit to helping with the discovery of evidence relating to the trial of 2021. In the months prior to their agreement, Facebook had been dealing with feuds against Apple relating to the prices of paid apps as well as privacy rule changes. Head of ad products for Facebook Dan Levy commented, saying that "this is not really about privacy for them, this is about an attack on personalized ads and the consequences it's going to have on small-business owners," commenting on the full-page ads placed by Facebook in various newspapers in December 2020. Customer privacy Apple has a notable pro-privacy stance, actively making privacy-conscious features and settings part of its conferences, promotional campaigns, and public image. With its iOS 8 mobile operating system in 2014, the company started encrypting all contents of iOS devices through users' passcodes, making it impossible at the time for the company to provide customer data to law enforcement requests seeking such information. With the popularity rise of cloud storage solutions, Apple began a technique in 2016 to do deep learning scans for facial data in photos on the user's local device and encrypting the content before uploading it to Apple's iCloud storage system. It also introduced "differential privacy", a way to collect crowdsourced data from many users, while keeping individual users anonymous, in a system that Wired described as "trying to learn as much as possible about a group while learning as little as possible about any individual in it". Users are explicitly asked if they want to participate, and can actively opt-in or opt-out. With Apple's release of an update to iOS 14, Apple required all developers of iPhone, iPad, and iPod Touch applications to directly ask iPhone users permission to track them. The feature, titled "App Tracking Transparency", received heavy criticism from Facebook, whose primary business model revolves around the tracking of users' data and sharing such data with advertisers so users can see more relevant ads, a technique commonly known as targeted advertising. Despite Facebook's measures, including purchasing full-page newspaper advertisements protesting App Tracking Transparency, Apple released the update in mid-spring 2021. A study by Verizon subsidiary Flurry Analytics reported only 4% of iOS users in the United States and 12% worldwide have opted into tracking. However, Apple aids law enforcement in criminal investigations by providing iCloud backups of users' devices, and the company's commitment to privacy has been questioned by its efforts to promote biometric authentication technology in its newer iPhone models, which don't have the same level of constitutional privacy as a passcode in the United States. Prior to the release of iOS 15, Apple announced new efforts at combating child sexual abuse material on iOS and Mac platforms. Parents of minor iMessage users can now be alerted if their child sends or receives nude photographs. Additionally, on-device hashing would take place on media destined for upload to iCloud, and hashes would be compared to a list of known abusive images provided by law enforcement; if enough matches were found, Apple would be alerted and authorities informed. The new features received praise from law enforcement and victims rights advocates, however privacy advocates, including the Electronic Frontier Foundation, condemned the new features as invasive and highly prone to abuse by authoritarian governments. Ireland's Data Protection Commission launched a privacy investigation to examine whether Apple complied with the EU's GDPR law following an investigation into how the company processes personal data with targeted ads on its platform. In December 2019, a report found that the iPhone 11 Pro continues tracking location and collecting user data even after users have disabled location services. In response, an Apple engineer said the Location Services icon "appears for system services that do not have a switch in settings." According to published reports by Bloomberg News on March 30, 2022, Apple turned over data such as phone numbers, physical addresses, and IP addresses to hackers posing as law enforcement officials using forged documents. The law enforcement requests sometimes included forged signatures of real or fictional officials. When asked about the allegations, an Apple representative referred the reporter to a section of the company policy for law enforcement guidelines, which stated, "We review every data request for legal sufficiency and use advanced systems and processes to validate law enforcement requests and detect abuse." Corporate affairs Leadership Senior management As of March 16, 2021, the management of Apple Inc. includes: Tim Cook (chief executive officer) Jeff Williams (chief operating officer) Luca Maestri (senior vice president and chief financial officer) Katherine L. Adams (senior vice president and general counsel) Eddy Cue (senior vice president – Internet Software and Services) Craig Federighi (senior vice president – Software Engineering) John Giannandrea (senior vice president – Machine Learning and AI Strategy) Deirdre O'Brien (senior vice president – Retail + People) John Ternus (senior vice president – Hardware Engineering) Greg Josiwak (senior vice president – Worldwide Marketing) Johny Srouji (senior vice president – Hardware Technologies) Sabih Khan (senior vice president – Operations) Board of directors As of January 20, 2023, the board of directors of Apple Inc. includes: Arthur D. Levinson (chairman) Tim Cook (executive director and CEO) James A. Bell Al Gore Alex Gorsky Andrea Jung Monica Lozano Ronald Sugar Susan Wagner Previous CEOs Michael Scott (1977–1981) Mike Markkula (1981–1983) John Sculley (1983–1993) Michael Spindler (1993–1996) Gil Amelio (1996–1997) Steve Jobs (1997–2011) Corporate culture Apple is one of several highly successful companies founded in the 1970s that bucked the traditional notions of corporate culture. Jobs often walked around the office barefoot even after Apple became a Fortune 500 company. By the time of the "1984" television advertisement, Apple's informal culture had become a key trait that differentiated it from its competitors. According to a 2011 report in Fortune, this has resulted in a corporate culture more akin to a startup rather than a multinational corporation. In a 2017 interview, Wozniak credited watching Star Trek and attending Star Trek conventions while in his youth as a source of inspiration for his co-founding Apple. As the company has grown and been led by a series of differently opinionated chief executives, it has arguably lost some of its original character. Nonetheless, it has maintained a reputation for fostering individuality and excellence that reliably attracts talented workers, particularly after Jobs returned to the company. Numerous Apple employees have stated that projects without Jobs's involvement often took longer than projects with it. To recognize the best of its employees, Apple created the Apple Fellows program which awards individuals who make extraordinary technical or leadership contributions to personal computing while at the company. The Apple Fellowship has so far been awarded to individuals including Bill Atkinson, Steve Capps, Rod Holt, Alan Kay, Guy Kawasaki, Al Alcorn, Don Norman, Rich Page, Steve Wozniak, and Phil Schiller. At Apple, employees are intended to be specialists who are not exposed to functions outside their area of expertise. Jobs saw this as a means of having "best-in-class" employees in every role. For instance, Ron Johnson—Senior Vice President of Retail Operations until November 1, 2011—was responsible for site selection, in-store service, and store layout, yet had no control of the inventory in his stores. This was done by Tim Cook, who had a background in supply-chain management. Apple is known for strictly enforcing accountability. Each project has a "directly responsible individual" or "DRI" in Apple jargon. As an example, when iOS senior vice president Scott Forstall refused to sign Apple's official apology for numerous errors in the redesigned Maps app, he was forced to resign. Unlike other major U.S. companies, Apple provides a relatively simple compensation policy for executives that does not include perks enjoyed by other CEOs like country club fees or private use of company aircraft. The company typically grants stock options to executives every other year. In 2015, Apple had 110,000 full-time employees. This increased to 116,000 full-time employees the next year, a notable hiring decrease, largely due to its first revenue decline. Apple does not specify how many of its employees work in retail, though its 2014 SEC filing put the number at approximately half of its employee base. In September 2017, Apple announced that it had over 123,000 full-time employees. Apple has a strong culture of corporate secrecy, and has an anti-leak Global Security team that recruits from the National Security Agency, the Federal Bureau of Investigation, and the United States Secret Service. In December 2017, Glassdoor said Apple was the 48th best place to work, having originally entered at rank 19 in 2009, peaking at rank 10 in 2012, and falling down the ranks in subsequent years. In 2023, Bloomberg's Mark Gurman revealed the existence of Apple's Exploratory Design Group (XDG), which was working to add glucose monitoring to the Apple Watch. Gurman compared XDG to Alphabet's X "moonshot factory". Offices Apple Inc.'s world corporate headquarters are located in Cupertino, in the middle of California's Silicon Valley, at Apple Park, a massive circular groundscraper building with a circumference of . The building opened in April 2017 and houses more than 12,000 employees. Apple co-founder Steve Jobs wanted Apple Park to look less like a business park and more like a nature refuge, and personally appeared before the Cupertino City Council in June 2011 to make the proposal, in his final public appearance before his death. Apple also operates from the Apple Campus (also known by its address, 1 Infinite Loop), a grouping of six buildings in Cupertino that total located about to the west of Apple Park. The Apple Campus was the company's headquarters from its opening in 1993, until the opening of Apple Park in 2017. The buildings, located at 1–6 Infinite Loop, are arranged in a circular pattern around a central green space, in a design that has been compared to that of a university. In addition to Apple Park and the Apple Campus, Apple occupies an additional thirty office buildings scattered throughout the city of Cupertino, including three buildings that also served as prior headquarters: "Stephens Creek Three" (1977–1978), Bandley One" (1978–1982), and "Mariani One" (1982–1993). In total, Apple occupies almost 40% of the available office space in the city. Apple's headquarters for Europe, the Middle East and Africa (EMEA) are located in Cork in the south of Ireland, called the Hollyhill campus. The facility, which opened in 1980, houses 5,500 people and was Apple's first location outside of the United States. Apple's international sales and distribution arms operate out of the campus in Cork. Apple has two campuses near Austin, Texas: a campus opened in 2014 houses 500 engineers who work on Apple silicon and a campus opened in 2021 where 6,000 people to work in technical support, supply chain management, online store curation, and Apple Maps data management. The company, also has several other locations in Boulder, Colorado, Culver City, California, Herzliya (Israel), London, New York, Pittsburgh, San Diego, and Seattle that each employ hundreds of people. Litigation Apple has been a participant in various legal proceedings and claims since it began operation. In particular, Apple is known for and promotes itself as actively and aggressively enforcing its intellectual property interests. Some litigation examples include Apple v. Samsung, Apple v. Microsoft, Motorola Mobility v. Apple Inc., and Apple Corps v. Apple Computer. Apple has also had to defend itself against charges on numerous occasions of violating intellectual property rights. Most have been dismissed in the courts as shell companies known as patent trolls, with no evidence of actual use of patents in question. On December 21, 2016, Nokia announced that in the U.S. and Germany, it has filed a suit against Apple, claiming that the latter's products infringe on Nokia's patents. Most recently, in November 2017, the United States International Trade Commission announced an investigation into allegations of patent infringement in regards to Apple's remote desktop technology; Aqua Connect, a company that builds remote desktop software, has claimed that Apple infringed on two of its patents. In January 2022, Ericsson sued Apple over payment of royalty of 5G technology. Finances Apple is the world's largest technology company by revenue, the world's largest technology company by total assets, and the world's second-largest mobile phone manufacturer after Samsung. In its fiscal year ending in September 2011, Apple Inc. reported a total of $108 billion in annual revenues—a significant increase from its 2010 revenues of $65 billion—and nearly $82 billion in cash reserves. On March 19, 2012, Apple announced plans for a $2.65-per-share dividend beginning in fourth quarter of 2012, per approval by their board of directors. The company's worldwide annual revenue in 2013 totaled $170 billion. In May 2013, Apple entered the top ten of the Fortune 500 list of companies for the first time, rising 11 places above its 2012 ranking to take the sixth position. , Apple has around US$234 billion of cash and marketable securities, of which 90% is located outside the United States for tax purposes. Apple amassed 65% of all profits made by the eight largest worldwide smartphone manufacturers in quarter one of 2014, according to a report by Canaccord Genuity. In the first quarter of 2015, the company garnered 92% of all earnings. On April 30, 2017, The Wall Street Journal reported that Apple had cash reserves of $250 billion, officially confirmed by Apple as specifically $256.8 billion a few days later. , Apple was the largest publicly traded corporation in the world by market capitalization. On August 2, 2018, Apple became the first publicly traded U.S. company to reach a $1 trillion market value. Apple was ranked No. 4 on the 2018 Fortune 500 rankings of the largest United States corporations by total revenue. In July 2022, Apple reported an 11% decline in Q3 profits compared to 2021. Its revenue in the same period rose 2% year-on-year to $83 billion, though this figure was also lower than in 2021, where the increase was at 36%. The general downturn is reportedly caused by the slowing global economy and supply chain disruptions in China. Taxes Apple has created subsidiaries in low-tax places such as Ireland, the Netherlands, Luxembourg, and the British Virgin Islands to cut the taxes it pays around the world. According to The New York Times, in the 1980s Apple was among the first tech companies to designate overseas salespeople in high-tax countries in a manner that allowed the company to sell on behalf of low-tax subsidiaries on other continents, sidestepping income taxes. In the late 1980s, Apple was a pioneer of an accounting technique known as the "Double Irish with a Dutch sandwich", which reduces taxes by routing profits through Irish subsidiaries and the Netherlands and then to the Caribbean. British Conservative Party Member of Parliament Charlie Elphicke published research on October 30, 2012, which showed that some multinational companies, including Apple Inc., were making billions of pounds of profit in the UK, but were paying an effective tax rate to the UK Treasury of only 3 percent, well below standard corporate tax rates. He followed this research by calling on the Chancellor of the Exchequer George Osborne to force these multinationals, which also included Google and The Coca-Cola Company, to state the effective rate of tax they pay on their UK revenues. Elphicke also said that government contracts should be withheld from multinationals who do not pay their fair share of UK tax. According to a US Senate report on the company's offshore tax structure concluded in May 2013, Apple has held billions of dollars in profits in Irish subsidiaries to pay little or no taxes to any government by using an unusual global tax structure. The main subsidiary, a holding company that includes Apple's retail stores throughout Europe, has not paid any corporate income tax in the last five years. "Apple has exploited a difference between Irish and U.S. tax residency rules", the report said. On May 21, 2013, Apple CEO Tim Cook defended his company's tax tactics at a Senate hearing. Apple says that it is the single largest taxpayer in the U.S., with an effective tax rate of approximately of 26% as of Q2 FY2016. In an interview with the German newspaper FAZ in October 2017, Tim Cook stated that Apple was the biggest taxpayer worldwide. In 2016, after a two-year investigation, the European Commission claimed that Apple's use of a hybrid Double Irish tax arrangement constituted "illegal state aid" from Ireland, and ordered Apple to pay 13 billion euros ($14.5 billion) in unpaid taxes, the largest corporate tax fine in history. This was later annulled, after the European General Court ruled that the Commission had provided insufficient evidence. In 2018, Apple repatriated $285 billion to America, resulting in a $38 billion tax payment spread over the following 8 years. Charity Apple is a partner of (PRODUCT)RED, a fundraising campaign for AIDS charity. In November 2014, Apple arranged for all App Store revenue in a two-week period to go to the fundraiser, generating more than US$20 million, and in March 2017, it released an iPhone 7 with a red color finish. Apple contributes financially to fundraisers in times of natural disasters. In November 2012, it donated $2.5 million to the American Red Cross to aid relief efforts after Hurricane Sandy, and in 2017 it donated $5 million to relief efforts for both Hurricane Irma and Hurricane Harvey, as well as for the 2017 Central Mexico earthquake. The company has also used its iTunes platform to encourage donations in the wake of environmental disasters and humanitarian crises, such as the 2010 Haiti earthquake, the 2011 Japan earthquake, Typhoon Haiyan in the Philippines in November 2013, and the 2015 European migrant crisis. Apple emphasizes that it does not incur any processing or other fees for iTunes donations, sending 100% of the payments directly to relief efforts, though it also acknowledges that the Red Cross does not receive any personal information on the users donating and that the payments may not be tax deductible. On April 14, 2016, Apple and the World Wide Fund for Nature (WWF) announced that they have engaged in a partnership to, "help protect life on our planet." Apple released a special page in the iTunes App Store, Apps for Earth. In the arrangement, Apple has committed that through April 24, WWF will receive 100% of the proceeds from the applications participating in the App Store via both the purchases of any paid apps and the In-App Purchases. Apple and WWF's Apps for Earth campaign raised more than $8 million in total proceeds to support WWF's conservation work. WWF announced the results at WWDC 2016 in San Francisco. During the COVID-19 pandemic, Apple's CEO Cook announced that the company will be donating "millions" of masks to health workers in the United States and Europe. On January 13, 2021, Apple announced a $100 million "Racial Equity and Justice Initiative" to help combat institutional racism worldwide. Environment Apple Energy Apple Energy, LLC is a wholly-owned subsidiary of Apple Inc. that sells solar energy. , Apple's solar farms in California and Nevada have been declared to provide 217.9 megawatts of solar generation capacity. In addition to the company's solar energy production, Apple has received regulatory approval to construct a landfill gas energy plant in North Carolina. Apple will use the methane emissions to generate electricity. Apple's North Carolina data center is already powered entirely with energy from renewable sources. Energy and resources Following a Greenpeace protest, Apple released a statement on April 17, 2012, committing to ending its use of coal and shifting to 100% renewable clean energy. By 2013, Apple was using 100% renewable energy to power their data centers. Overall, 75% of the company's power came from clean renewable sources. In 2010, Climate Counts, a nonprofit organization dedicated to directing consumers toward the greenest companies, gave Apple a score of 52 points out of a possible 100, which puts Apple in their top category "Striding". This was an increase from May 2008, when Climate Counts only gave Apple 11 points out of 100, which placed the company last among electronics companies, at which time Climate Counts also labeled Apple with a "stuck icon", adding that Apple at the time was "a choice to avoid for the climate-conscious consumer". In May 2015, Greenpeace evaluated the state of the Green Internet and commended Apple on their environmental practices saying, "Apple's commitment to renewable energy has helped set a new bar for the industry, illustrating in very concrete terms that a 100% renewable Internet is within its reach, and providing several models of intervention for other companies that want to build a sustainable Internet." , Apple states that 100% of its U.S. operations run on renewable energy, 100% of Apple's data centers run on renewable energy and 93% of Apple's global operations run on renewable energy. However, the facilities are connected to the local grid which usually contains a mix of fossil and renewable sources, so Apple carbon offsets its electricity use. The Electronic Product Environmental Assessment Tool (EPEAT) allows consumers to see the effect a product has on the environment. Each product receives a Gold, Silver, or Bronze rank depending on its efficiency and sustainability. Every Apple tablet, notebook, desktop computer, and display that EPEAT ranks achieves a Gold rating, the highest possible. Although Apple's data centers recycle water 35 times, the increased activity in retail, corporate and data centers also increase the amount of water use to in 2015. During an event on March 21, 2016, Apple provided a status update on its environmental initiative to be 100% renewable in all of its worldwide operations. Lisa P. Jackson, Apple's vice president of Environment, Policy and Social Initiatives who reports directly to CEO, Tim Cook, announced that , 93% of Apple's worldwide operations are powered with renewable energy. Also featured was the company's efforts to use sustainable paper in their product packaging; 99% of all paper used by Apple in the product packaging comes from post-consumer recycled paper or sustainably managed forests, as the company continues its move to all paper packaging for all of its products. Apple working in partnership with Conservation Fund, have preserved 36,000 acres of working forests in Maine and North Carolina. Another partnership announced is with the World Wildlife Fund to preserve up to of forests in China. Featured was the company's installation of a 40 MW solar power plant in the Sichuan province of China that was tailor-made to coexist with the indigenous yaks that eat hay produced on the land, by raising the panels to be several feet off of the ground so the yaks and their feed would be unharmed grazing beneath the array. This installation alone compensates for more than all of the energy used in Apple's Stores and Offices in the whole of China, negating the company's energy carbon footprint in the country. In Singapore, Apple has worked with the Singaporean government to cover the rooftops of 800 buildings in the city-state with solar panels allowing Apple's Singapore operations to be run on 100% renewable energy. Liam was introduced to the world, an advanced robotic disassembler and sorter designed by Apple Engineers in California specifically for recycling outdated or broken iPhones. Reuses and recycles parts from traded in products. Apple announced on August 16, 2016, that Lens Technology, one of its major suppliers in China, has committed to power all its glass production for Apple with 100 percent renewable energy by 2018. The commitment is a large step in Apple's efforts to help manufacturers lower their carbon footprint in China. Apple also announced that all 14 of its final assembly sites in China are now compliant with UL's Zero Waste to Landfill validation. The standard, which started in January 2015, certifies that all manufacturing waste is reused, recycled, composted, or converted into energy (when necessary). Since the program began, nearly 140,000 metric tons of waste have been diverted from landfills. On July 21, 2020, Apple announced its plan to become carbon neutral across its entire business, manufacturing supply chain, and product life cycle by 2030. In the next 10 years, Apple will try to lower emissions with a series of innovative actions, including: low carbon product design, expanding energy efficiency, renewable energy, process and material innovations, and carbon removal. In April 2021, Apple said that it had started a $200 million fund in order to combat climate change by removing 1 million metric tons of carbon dioxide from the atmosphere each year. Toxins Following further campaigns by Greenpeace, in 2008, Apple became the first electronics manufacturer to eliminate all polyvinyl chloride (PVC) and brominated flame retardants (BFRs) in its complete product line. In June 2007, Apple began replacing the cold cathode fluorescent lamp (CCFL) backlit LCD displays in its computers with mercury-free LED-backlit LCD displays and arsenic-free glass, starting with the upgraded MacBook Pro. Apple offers comprehensive and transparent information about the CO2e, emissions, materials, and electrical usage concerning every product they currently produce or have sold in the past (and which they have enough data needed to produce the report), in their portfolio on their homepage. Allowing consumers to make informed purchasing decisions on the products they offer for sale. In June 2009, Apple's iPhone 3GS was free of PVC, arsenic, and BFRs. All Apple products now have mercury-free LED-backlit LCD displays, arsenic-free glass, and non-PVC cables. All Apple products have EPEAT Gold status and beat the latest Energy Star guidelines in each product's respective regulatory category. In November 2011, Apple was featured in Greenpeace's Guide to Greener Electronics, which ranks electronics manufacturers on sustainability, climate and energy policy, and how "green" their products are. The company ranked fourth of fifteen electronics companies (moving up five places from the previous year) with a score of 4.6/10. Greenpeace praises Apple's sustainability, noting that the company exceeded its 70% global recycling goal in 2010. It continues to score well on the products rating with all Apple products now being free of PVC plastic and BFRs. However, the guide criticizes Apple on the Energy criteria for not seeking external verification of its greenhouse gas emissions data and for not setting out any targets to reduce emissions. In January 2012, Apple requested that its cable maker, Volex, begin producing halogen-free USB and power cables. Green bonds In February 2016, Apple issued a US$1.5 billion green bond (climate bond), the first ever of its kind by a U.S. tech company. The green bond proceeds are dedicated to the financing of environmental projects. Supply chain Apple products were made in America in Apple-owned factories until the late 1990s; however, as a result of outsourcing initiatives in the 2000s, almost all of its manufacturing is now handled abroad. According to a report by The New York Times, Apple insiders "believe the vast scale of overseas factories, as well as the flexibility, diligence and industrial skills of foreign workers, have so outpaced their American counterparts that "Made in the USA" is no longer a viable option for most Apple products". The company's manufacturing, procurement, and logistics enable it to execute massive product launches without having to maintain large, profit-sapping inventories. In 2011, Apple's profit margins were 40 percent, compared with between 10 and 20 percent for most other hardware companies. Cook's catchphrase to describe his focus on the company's operational arm is: "Nobody wants to buy sour milk." In May 2017, the company announced a $1 billion funding project for "advanced manufacturing" in the United States, and subsequently invested $200 million in Corning Inc., a manufacturer of toughened Gorilla Glass technology used in its iPhone devices. The following December, Apple's chief operating officer, Jeff Williams, told CNBC that the "$1 billion" amount was "absolutely not" the final limit on its spending, elaborating that "We're not thinking in terms of a fund limit... We're thinking about, where are the opportunities across the U.S. to help nurture companies that are making the advanced technology— and the advanced manufacturing that goes with that— that quite frankly is essential to our innovation." As of 2021, Apple uses components from 43 countries. The majority of assembling is done by Taiwanese original design manufacturer firms Foxconn, Pegatron, Wistron and Compal Electronics with factories mostly located inside China, but also Brazil, and India. Taiwan Semiconductor Manufacturing Co., (TSMC) is a pure-play semiconductor manufacturing company. They make the majority of Apple's smartphone SoCs, with Samsung Semiconductor, playing a minority role. Apple, alone accounted for over 25% of TSMC's total income in 2021. Apple's Bionic lineup of smartphone SoCs, are currently made exclusively by TSMC from the A7 bionic onwards, previously manufacturing was shared with Samsung. The M series of Apple SoC for consumer computers and tablets is made by TSMC as well. During the Mac's early history Apple generally refused to adopt prevailing industry standards for hardware, instead creating their own. This trend was largely reversed in the late 1990s, beginning with Apple's adoption of the PCI bus in the 7500/8500/9500 Power Macs. Apple has since joined the industry standards groups to influence the future direction of technology standards such as USB, AGP, HyperTransport, Wi-Fi, NVMe, PCIe and others in its products. FireWire is an Apple-originated standard that was widely adopted across the industry after it was standardized as IEEE 1394 and is a legally mandated port in all Cable TV boxes in the United States. Apple has gradually expanded its efforts in getting its products into the Indian market. In July 2012, during a conference call with investors, CEO Tim Cook said that he "[loves] India", but that Apple saw larger opportunities outside the region. India's requirement that 30% of products sold be manufactured in the country was described as "really adds cost to getting product to market". In May 2016, Apple opened an iOS app development center in Bangalore and a maps development office for 4,000 staff in Hyderabad. In March, The Wall Street Journal reported that Apple would begin manufacturing iPhone models in India "over the next two months", and in May, the Journal wrote that an Apple manufacturer had begun production of iPhone SE in the country, while Apple told CNBC that the manufacturing was for a "small number" of units. In April 2019, Apple initiated manufacturing of iPhone 7 at its Bengaluru facility, keeping in mind demand from local customers even as they seek more incentives from the government of India. At the beginning of 2020, Tim Cook announced that Apple schedules the opening of its first physical outlet in India for 2021, while an online store is to be launched by the end of the year. Worker organizations In 2006, one complex of factories in Shenzhen, China that assembled the iPod and other items had over 200,000 workers living and working within it. Employees regularly worked more than 60 hours per week and made around $100 per month. A little over half of the workers' earnings was required to pay for rent and food from the company. Apple immediately launched an investigation after the 2006 media report, and worked with their manufacturers to ensure acceptable working conditions. In 2007, Apple started yearly audits of all its suppliers regarding worker's rights, slowly raising standards and pruning suppliers that did not comply. Yearly progress reports have been published since 2008. In 2011, Apple admitted that its suppliers' child labor practices in China had worsened. The Foxconn suicides occurred between January and November 2010, when 18 Foxconn (Chinese: 富士康) employees attempted suicide, resulting in 14 deaths—the company was the world's largest contract electronics manufacturer, for clients including Apple, at the time. The suicides drew media attention, and employment practices at Foxconn were investigated by Apple. Apple issued a public statement about the suicides, and company spokesperson Steven Dowling said: The statement was released after the results from the company's probe into its suppliers' labor practices were published in early 2010. Foxconn was not specifically named in the report, but Apple identified a series of serious labor violations of labor laws, including Apple's own rules, and some child labor existed in a number of factories. Apple committed to the implementation of changes following the suicides. Also in 2010, workers in China planned to sue iPhone contractors over poisoning by a cleaner used to clean LCD screens. One worker claimed that he and his coworkers had not been informed of possible occupational illnesses. After a high suicide rate in a Foxconn facility in China making iPads and iPhones, albeit a lower rate than that of China as a whole, workers were forced to sign a legally binding document guaranteeing that they would not kill themselves. Workers in factories producing Apple products have also been exposed to hexane, a neurotoxin that is a cheaper alternative than alcohol for cleaning the products. A 2014 BBC investigation found excessive hours and other problems persisted, despite Apple's promise to reform factory practice after the 2010 Foxconn suicides. The Pegatron factory was once again the subject of review, as reporters gained access to the working conditions inside through recruitment as employees. While the BBC maintained that the experiences of its reporters showed that labor violations were continuing since 2010, Apple publicly disagreed with the BBC and stated: "We are aware of no other company doing as much as Apple to ensure fair and safe working conditions". In December 2014, the Institute for Global Labour and Human Rights published a report which documented inhumane conditions for the 15,000 workers at a Zhen Ding Technology factory in Shenzhen, China, which serves as a major supplier of circuit boards for Apple's iPhone and iPad. According to the report, workers are pressured into 65-hour work weeks which leaves them so exhausted that they often sleep during lunch breaks. They are also made to reside in "primitive, dark and filthy dorms" where they sleep "on plywood, with six to ten workers in each crowded room." Omnipresent security personnel also routinely harass and beat the workers.

Alfons Maria Jakob

Alfons Maria Jakob (2 July 1884 – 17 October 1931) was a German neurologist who worked in the field of neuropathology. He was born in Aschaffenburg, Bavaria and educated in medicine at the universities of Munich, Berlin, and Strasbourg, where he received his doctorate in 1908. During the following year, he began clinical work under the psychiatrist Emil Kraepelin and did laboratory work with Franz Nissl and Alois Alzheimer in Munich. In 1911, by way of an invitation from Wilhelm Weygandt, he relocated to Hamburg, where he worked with Theodor Kaes and eventually became head of the laboratory of anatomical pathology at the psychiatric State Hospital Hamburg-Friedrichsberg. Following the death of Kaes in 1913, Jakob succeeded him as prosector. During World War I he served as an army physician in Belgium, and afterwards returned to Hamburg. In 1919, he obtained his habilitation for neurology and in 1924 became a professor of neurology. Under Jakob's guidance the department grew rapidly. He made significant contributions to knowledge on concussion and secondary nerve degeneration and became a doyen of neuropathology. Jakob was the author of five monographs and nearly 80 scientific papers. His neuropathological research contributed greatly to the delineation of several diseases, including multiple sclerosis and Friedreich's ataxia. He first recognised and described Alper's disease and Creutzfeldt–Jakob disease (named along with Munich neuropathologist Hans Gerhard Creutzfeldt). He gained experience in neurosyphilis, having a 200-bed ward devoted entirely to that disorder. Jakob made a lecture tour of the United States (1924) and South America (1928), of which, he wrote a paper on the neuropathology of yellow fever. He suffered from chronic osteomyelitis for the last seven years of his life. This eventually caused a retroperitoneal abscess and paralytic ileus from which he died following operation.

Agnosticism

Agnosticism is the view or belief that the existence of God, of the divine or the supernatural is unknown or unknowable. Another definition provided is the view that "human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist." The English biologist Thomas Henry Huxley coined the word agnostic in 1869, and said "It simply means that a man shall not say he knows or believes that which he has no scientific grounds for professing to know or believe." Earlier thinkers, however, had written works that promoted agnostic points of view, such as Sanjaya Belatthaputta, a 5th-century BCE Indian philosopher who expressed agnosticism about any afterlife; and Protagoras, a 5th-century BCE Greek philosopher who expressed agnosticism about the existence of "the gods". Defining agnosticism Being a scientist, above all else, Huxley presented agnosticism as a form of demarcation. A hypothesis with no supporting, objective, testable evidence is not an objective, scientific claim. As such, there would be no way to test said hypotheses, leaving the results inconclusive. His agnosticism was not compatible with forming a belief as to the truth, or falsehood, of the claim at hand. Karl Popper would also describe himself as an agnostic. According to philosopher William L. Rowe, in this strict sense, agnosticism is the view that human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist. George H. Smith, while admitting that the narrow definition of atheist was the common usage definition of that word, and admitting that the broad definition of agnostic was the common usage definition of that word, promoted broadening the definition of atheist and narrowing the definition of agnostic. Smith rejects agnosticism as a third alternative to theism and atheism and promotes terms such as agnostic atheism (the view of those who do not hold a belief in the existence of any deity, but claim that the existence of a deity is unknown or inherently unknowable) and agnostic theism (the view of those who believe in the existence of a deity(s), but claim that the existence of a deity is unknown or inherently unknowable). Etymology Agnostic () was used by Thomas Henry Huxley in a speech at a meeting of the Metaphysical Society in 1869 to describe his philosophy, which rejects all claims of spiritual or mystical knowledge. Early Christian church leaders used the Greek word gnosis (knowledge) to describe "spiritual knowledge". Agnosticism is not to be confused with religious views opposing the ancient religious movement of Gnosticism in particular; Huxley used the term in a broader, more abstract sense. Huxley identified agnosticism not as a creed but rather as a method of skeptical, evidence-based inquiry. The term Agnostic is also cognate with the Sanskrit word Ajñasi which translates literally to "not knowable", and relates to the ancient Indian philosophical school of Ajñana, which proposes that it is impossible to obtain knowledge of metaphysical nature or ascertain the truth value of philosophical propositions; and even if knowledge was possible, it is useless and disadvantageous for final salvation. In recent years, scientific literature dealing with neuroscience and psychology has used the word to mean "not knowable". In technical and marketing literature, "agnostic" can also mean independence from some parameters—for example, "platform agnostic" (referring to cross-platform software) or "hardware-agnostic". Qualifying agnosticism Scottish Enlightenment philosopher David Hume contended that meaningful statements about the universe are always qualified by some degree of doubt. He asserted that the fallibility of human beings means that they cannot obtain absolute certainty except in trivial cases where a statement is true by definition (e.g. tautologies such as "all bachelors are unmarried" or "all triangles have three corners"). Types Strong agnosticism (also called "hard", "closed", "strict", or "permanent agnosticism") The view that the question of the existence or nonexistence of a deity or deities, and the nature of ultimate reality is unknowable by reason of our natural inability to verify any experience with anything but another subjective experience. A strong agnostic would say, "I cannot know whether a deity exists or not, and neither can you." Weak agnosticism (also called "soft", "open", "empirical", "hopeful" or "temporal agnosticism") The view that the existence or nonexistence of any deities is currently unknown but is not necessarily unknowable; therefore, one will withhold judgment until evidence, if any, becomes available. A weak agnostic would say, "I don't know whether any deities exist or not, but maybe one day, if there is evidence, we can find something out." Apathetic agnosticism The view that no amount of debate can prove or disprove the existence of one or more deities, and if one or more deities exist, they do not appear to be concerned about the fate of humans. Therefore, their existence has little to no impact on personal human affairs and should be of little interest. An apathetic agnostic would say, "I don't know whether any deity exists or not, and I don't care if any deity exists or not." History Hindu philosophy Throughout the history of Hinduism there has been a strong tradition of philosophic speculation and skepticism. The Rig Veda takes an agnostic view on the fundamental question of how the universe and the gods were created. Nasadiya Sukta (Creation Hymn) in the tenth chapter of the Rig Veda says: Hume, Kant, and Kierkegaard Aristotle, Anselm, Aquinas, Descartes, and Gödel presented arguments attempting to rationally prove the existence of God. The skeptical empiricism of David Hume, the antinomies of Immanuel Kant, and the existential philosophy of Søren Kierkegaard convinced many later philosophers to abandon these attempts, regarding it impossible to construct any unassailable proof for the existence or non-existence of God. In his 1844 book, Philosophical Fragments, Kierkegaard writes: Hume was Huxley's favourite philosopher, calling him "the Prince of Agnostics". Diderot wrote to his mistress, telling of a visit by Hume to the Baron D'Holbach, and describing how a word for the position that Huxley would later describe as agnosticism did not seem to exist, or at least was not common knowledge, at the time. United Kingdom Charles Darwin Raised in a religious environment, Charles Darwin (1809–1882) studied to be an Anglican clergyman. While eventually doubting parts of his faith, Darwin continued to help in church affairs, even while avoiding church attendance. Darwin stated that it would be "absurd to doubt that a man might be an ardent theist and an evolutionist". Although reticent about his religious views, in 1879 he wrote that "I have never been an atheist in the sense of denying the existence of a God. – I think that generally ... an agnostic would be the most correct description of my state of mind." Thomas Henry Huxley Agnostic views are as old as philosophical skepticism, but the terms agnostic and agnosticism were created by Huxley (1825–1895) to sum up his thoughts on contemporary developments of metaphysics about the "unconditioned" (William Hamilton) and the "unknowable" (Herbert Spencer). Though Huxley began to use the term "agnostic" in 1869, his opinions had taken shape some time before that date. In a letter of September 23, 1860, to Charles Kingsley, Huxley discussed his views extensively: And again, to the same correspondent, May 6, 1863: Of the origin of the name agnostic to describe this attitude, Huxley gave the following account: In 1889, Huxley wrote: William Stewart Ross William Stewart Ross (1844–1906) wrote under the name of Saladin. He was associated with Victorian Freethinkers and the organization the British Secular Union. He edited the Secular Review from 1882; it was renamed Agnostic Journal and Eclectic Review and closed in 1907. Ross championed agnosticism in opposition to the atheism of Charles Bradlaugh as an open-ended spiritual exploration. In Why I am an Agnostic () he claims that agnosticism is "the very reverse of atheism". Bertrand Russell Bertrand Russell (1872–1970) declared Why I Am Not a Christian in 1927, a classic statement of agnosticism. He calls upon his readers to "stand on their own two feet and look fair and square at the world with a fearless attitude and a free intelligence". In 1939, Russell gave a lecture on The existence and nature of God, in which he characterized himself as an atheist. He said: However, later in the same lecture, discussing modern non-anthropomorphic concepts of God, Russell states: In Russell's 1947 pamphlet, Am I An Atheist or an Agnostic? (subtitled A Plea For Tolerance in the Face of New Dogmas), he ruminates on the problem of what to call himself: In his 1953 essay, What Is An Agnostic? Russell states: Later in the essay, Russell adds: Leslie Weatherhead In 1965, Christian theologian Leslie Weatherhead (1893–1976) published The Christian Agnostic, in which he argues: Although radical and unpalatable to conventional theologians, Weatherhead's agnosticism falls far short of Huxley's, and short even of weak agnosticism: United States Robert G. Ingersoll Robert G. Ingersoll (1833–1899), an Illinois lawyer and politician who evolved into a well-known and sought-after orator in 19th-century America, has been referred to as the "Great Agnostic". In an 1896 lecture titled Why I Am An Agnostic, Ingersoll related why he was an agnostic: In the conclusion of the speech he simply sums up the agnostic position as: In 1885, Ingersoll explained his comparative view of agnosticism and atheism as follows: Bernard Iddings Bell Canon Bernard Iddings Bell (1886–1958), a popular cultural commentator, Episcopal priest, and author, lauded the necessity of agnosticism in Beyond Agnosticism: A Book for Tired Mechanists, calling it the foundation of "all intelligent Christianity". Agnosticism was a temporary mindset in which one rigorously questioned the truths of the age, including the way in which one believed God. His view of Robert Ingersoll and Thomas Paine was that they were not denouncing true Christianity but rather "a gross perversion of it". Part of the misunderstanding stemmed from ignorance of the concepts of God and religion. Historically, a god was any real, perceivable force that ruled the lives of humans and inspired admiration, love, fear, and homage; religion was the practice of it. Ancient peoples worshiped gods with real counterparts, such as Mammon (money and material things), Nabu (rationality), or Ba'al (violent weather); Bell argued that modern peoples were still paying homage—with their lives and their children's lives—to these old gods of wealth, physical appetites, and self-deification. Thus, if one attempted to be agnostic passively, he or she would incidentally join the worship of the world's gods. In Unfashionable Convictions (1931), he criticized the Enlightenment's complete faith in human sensory perception, augmented by scientific instruments, as a means of accurately grasping Reality. Firstly, it was fairly new, an innovation of the Western World, which Aristotle invented and Thomas Aquinas revived among the scientific community. Secondly, the divorce of "pure" science from human experience, as manifested in American Industrialization, had completely altered the environment, often disfiguring it, so as to suggest its insufficiency to human needs. Thirdly, because scientists were constantly producing more data—to the point where no single human could grasp it all at once—it followed that human intelligence was incapable of attaining a complete understanding of universe; therefore, to admit the mysteries of the unobserved universe was to be actually scientific. Bell believed that there were two other ways that humans could perceive and interact with the world. Artistic experience was how one expressed meaning through speaking, writing, painting, gesturing—any sort of communication which shared insight into a human's inner reality. Mystical experience was how one could "read" people and harmonize with them, being what we commonly call love. In summary, man was a scientist, artist, and lover. Without exercising all three, a person became "lopsided". Bell considered a humanist to be a person who cannot rightly ignore the other ways of knowing. However, humanism, like agnosticism, was also temporal, and would eventually lead to either scientific materialism or theism. He lays out the following thesis: Truth cannot be discovered by reasoning on the evidence of scientific data alone. Modern peoples' dissatisfaction with life is the result of depending on such incomplete data. Our ability to reason is not a way to discover Truth but rather a way to organize our knowledge and experiences somewhat sensibly. Without a full, human perception of the world, one's reason tends to lead them in the wrong direction. Beyond what can be measured with scientific tools, there are other types of perception, such as one's ability know another human through loving. One's loves cannot be dissected and logged in a scientific journal, but we know them far better than we know the surface of the sun. They show us an undefinable reality that is nevertheless intimate and personal, and they reveal qualities lovelier and truer than detached facts can provide. To be religious, in the Christian sense, is to live for the Whole of Reality (God) rather than for a small part (gods). Only by treating this Whole of Reality as a person—good and true and perfect—rather than an impersonal force, can we come closer to the Truth. An ultimate Person can be loved, but a cosmic force cannot. A scientist can only discover peripheral truths, but a lover is able to get at the Truth. There are many reasons to believe in God but they are not sufficient for an agnostic to become a theist. It is not enough to believe in an ancient holy book, even though when it is accurately analyzed without bias, it proves to be more trustworthy and admirable than what we are taught in school. Neither is it enough to realize how probable it is that a personal God would have to show human beings how to live, considering they have so much trouble on their own. Nor is it enough to believe for the reason that, throughout history, millions of people have arrived at this Wholeness of Reality only through religious experience. The aforementioned reasons may warm one toward religion, but they fall short of convincing. However, if one presupposes that God is in fact a knowable, loving person, as an experiment, and then lives according that religion, he or she will suddenly come face to face with experiences previously unknown. One's life becomes full, meaningful, and fearless in the face of death. It does not defy reason but exceeds it. Because God has been experienced through love, the orders of prayer, fellowship, and devotion now matter. They create order within one's life, continually renewing the "missing piece" that had previously felt lost. They empower one to be compassionate and humble, not small-minded or arrogant. No truth should be denied outright, but all should be questioned. Science reveals an ever-growing vision of our universe that should not be discounted due to bias toward older understandings. Reason is to be trusted and cultivated. To believe in God is not to forego reason or to deny scientific facts, but to step into the unknown and discover the fullness of life. Demographics Demographic research services normally do not differentiate between various types of non-religious respondents, so agnostics are often classified in the same category as atheists or other non-religious people. A 2010 survey published in Encyclopædia Britannica found that the non-religious people or the agnostics made up about 9.6% of the world's population. A November–December 2006 poll published in the Financial Times gives rates for the United States and five European countries. The rates of agnosticism in the United States were at 14%, while the rates of agnosticism in the European countries surveyed were considerably higher: Italy (20%), Spain (30%), Great Britain (35%), Germany (25%), and France (32%). A study conducted by the Pew Research Center found that about 16% of the world's people, the third largest group after Christianity and Islam, have no religious affiliation. According to a 2012 report by the Pew Research Center, agnostics made up 3.3% of the US adult population. In the U.S. Religious Landscape Survey, conducted by the Pew Research Center, 55% of agnostic respondents expressed "a belief in God or a universal spirit", whereas 41% stated that they thought that they felt a tension "being non-religious in a society where most people are religious". According to the 2011 Australian Bureau of Statistics, 22% of Australians have "no religion", a category that includes agnostics. Between 64% and 65% of Japanese and up to 81% of Vietnamese are atheists, agnostics, or do not believe in a god. An official European Union survey reported that 3% of the EU population is unsure about their belief in a god or spirit. Criticism Agnosticism is criticized from a variety of standpoints. Some atheists criticize the use of the term agnosticism as functionally indistinguishable from atheism; this results in frequent criticisms of those who adopt the term as avoiding the atheist label. Theistic Theistic critics claim that agnosticism is impossible in practice, since a person can live only either as if God did not exist (etsi deus non-daretur), or as if God did exist (etsi deus daretur). Christian According to Pope Benedict XVI, strong agnosticism in particular contradicts itself in affirming the power of reason to know scientific truth. He blames the exclusion of reasoning from religion and ethics for dangerous pathologies such as crimes against humanity and ecological disasters. "Agnosticism", said Benedict, "is always the fruit of a refusal of that knowledge which is in fact offered to man ... The knowledge of God has always existed". He asserted that agnosticism is a choice of comfort, pride, dominion, and utility over truth, and is opposed by the following attitudes: the keenest self-criticism, humble listening to the whole of existence, the persistent patience and self-correction of the scientific method, a readiness to be purified by the truth. The Catholic Church sees merit in examining what it calls "partial agnosticism", specifically those systems that "do not aim at constructing a complete philosophy of the unknowable, but at excluding special kinds of truth, notably religious, from the domain of knowledge". However, the Church is historically opposed to a full denial of the capacity of human reason to know God. The Council of the Vatican declares, "God, the beginning and end of all, can, by the natural light of human reason, be known with certainty from the works of creation". Blaise Pascal argued that even if there were truly no evidence for God, agnostics should consider what is now known as Pascal's Wager: the infinite expected value of acknowledging God is always greater than the finite expected value of not acknowledging his existence, and thus it is a safer "bet" to choose God. Atheistic According to Richard Dawkins, a distinction between agnosticism and atheism is unwieldy and depends on how close to zero a person is willing to rate the probability of existence for any given god-like entity. About himself, Dawkins continues, "I am agnostic only to the extent that I am agnostic about fairies at the bottom of the garden." Dawkins also identifies two categories of agnostics; "Temporary Agnostics in Practice" (TAPs), and "Permanent Agnostics in Principle" (PAPs). He states that "agnosticism about the existence of God belongs firmly in the temporary or TAP category. Either he exists or he doesn't. It is a scientific question; one day we may know the answer, and meanwhile we can say something pretty strong about the probability" and considers PAP a "deeply inescapable kind of fence-sitting". Ignosticism A related concept is ignosticism, the view that a coherent definition of a deity must be put forward before the question of the existence of a deity can be meaningfully discussed. If the chosen definition is not coherent, the ignostic holds the noncognitivist view that the existence of a deity is meaningless or empirically untestable. A. J. Ayer, Theodore Drange, and other philosophers see both atheism and agnosticism as incompatible with ignosticism on the grounds that atheism and agnosticism accept the statement "a deity exists" as a meaningful proposition that can be argued for or against.

Astatine

Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours. A sample of the pure element has never been assembled, because any macroscopic specimen would be immediately vaporized by the heat of its own radioactivity. The bulk properties of astatine are not known with certainty. Many of them have been estimated from the element's position on the periodic table as a heavier analog of iodine, and a member of the halogens (the group of elements including fluorine, chlorine, bromine, and iodine). However, astatine also falls roughly along the dividing line between metals and nonmetals, and some metallic behavior has also been observed and predicted for it. Astatine is likely to have a dark or lustrous appearance and may be a semiconductor or possibly a metal. Chemically, several anionic species of astatine are known and most of its compounds resemble those of iodine, but it also sometimes displays metallic characteristics and shows some similarities to silver. The first synthesis of the element was in 1940 by Dale R. Corson, Kenneth Ross MacKenzie, and Emilio G. Segrè at the University of California, Berkeley, who named it from the Ancient Greek () 'unstable'. Four isotopes of astatine were subsequently found to be naturally occurring, although much less than one gram is present at any given time in the Earth's crust. Neither the most stable isotope astatine-210, nor the medically useful astatine-211, occur naturally; they can only be produced synthetically, usually by bombarding bismuth-209 with alpha particles. Characteristics Astatine is an extremely radioactive element; all its isotopes have half-lives of 8.1 hours or less, decaying into other astatine isotopes, bismuth, polonium, or radon. Most of its isotopes are very unstable, with half-lives of one second or less. Of the first 101 elements in the periodic table, only francium is less stable, and all the astatine isotopes more stable than francium are in any case synthetic and do not occur in nature. The bulk properties of astatine are not known with any certainty. Research is limited by its short half-life, which prevents the creation of weighable quantities. A visible piece of astatine would immediately vaporize itself because of the heat generated by its intense radioactivity. It remains to be seen if, with sufficient cooling, a macroscopic quantity of astatine could be deposited as a thin film. Astatine is usually classified as either a nonmetal or a metalloid; metal formation has also been predicted. Physical Most of the physical properties of astatine have been estimated (by interpolation or extrapolation), using theoretically or empirically derived methods. For example, halogens get darker with increasing atomic weight – fluorine is nearly colorless, chlorine is yellow green, bromine is red brown, and iodine is dark gray/violet. Astatine is sometimes described as probably being a black solid (assuming it follows this trend), or as having a metallic appearance (if it is a metalloid or a metal). Astatine sublimes less readily than does iodine, having a lower vapor pressure. Even so, half of a given quantity of astatine will vaporize in approximately an hour if put on a clean glass surface at room temperature. The absorption spectrum of astatine in the middle ultraviolet region has lines at 224.401 and 216.225 nm, suggestive of 6p to 7s transitions. The structure of solid astatine is unknown. As an analogue of iodine it may have an orthorhombic crystalline structure composed of diatomic astatine molecules, and be a semiconductor (with a band gap of 0.7 eV). Alternatively, if condensed astatine forms a metallic phase, as has been predicted, it may have a monatomic face-centered cubic structure; in this structure it may well be a superconductor, like the similar high-pressure phase of iodine. Metallic astatine is expected to have a density of 8.91–8.95 g/cm3. Evidence for (or against) the existence of diatomic astatine (At2) is sparse and inconclusive. Some sources state that it does not exist, or at least has never been observed, while other sources assert or imply its existence. Despite this controversy, many properties of diatomic astatine have been predicted; for example, its bond length would be , dissociation energy , and heat of vaporization (∆Hvap) 54.39 kJ/mol. Many values have been predicted for the melting and boiling points of astatine, but only for At2. Chemical The chemistry of astatine is "clouded by the extremely low concentrations at which astatine experiments have been conducted, and the possibility of reactions with impurities, walls and filters, or radioactivity by-products, and other unwanted nano-scale interactions". Many of its apparent chemical properties have been observed using tracer studies on extremely dilute astatine solutions, typically less than 10−10 mol·L−1. Some properties, such as anion formation, align with other halogens. Astatine has some metallic characteristics as well, such as plating onto a cathode, and coprecipitating with metal sulfides in hydrochloric acid. It forms complexes with EDTA, a metal chelating agent, and is capable of acting as a metal in antibody radiolabeling; in some respects astatine in the +1 state is akin to silver in the same state. Most of the organic chemistry of astatine is, however, analogous to that of iodine. It has been suggested that astatine can form a stable monatomic cation in aqueous solution, but electromigration evidence suggests that the cationic At(I) species is protonated hypoastatous acid (H2OAt+), showing analogy to iodine. Astatine has an electronegativity of 2.2 on the revised Pauling scale – lower than that of iodine (2.66) and the same as hydrogen. In hydrogen astatide (HAt), the negative charge is predicted to be on the hydrogen atom, implying that this compound could be referred to as astatine hydride according to certain nomenclatures. That would be consistent with the electronegativity of astatine on the Allred–Rochow scale (1.9) being less than that of hydrogen (2.2). However, official IUPAC stoichiometric nomenclature is based on an idealized convention of determining the relative electronegativities of the elements by the mere virtue of their position within the periodic table. According to this convention, astatine is handled as though it is more electronegative than hydrogen, irrespective of its true electronegativity. The electron affinity of astatine, at 233 kJ mol−1, is 21% less than that of iodine. In comparison, the value of Cl (349) is 6.4% higher than F (328); Br (325) is 6.9% less than Cl; and I (295) is 9.2% less than Br. The marked reduction for At was predicted as being due to spin–orbit interactions. The first ionisation energy of astatine is about 899 kJ mol−1, which continues the trend of decreasing first ionisation energies down the halogen group (fluorine, 1681; chlorine, 1251; bromine, 1140; iodine, 1008). Compounds Less reactive than iodine, astatine is the least reactive of the halogens. Its compounds have been synthesized in nano-scale amounts and studied as intensively as possible before their radioactive disintegration. The reactions involved have been typically tested with dilute solutions of astatine mixed with larger amounts of iodine. Acting as a carrier, the iodine ensures there is sufficient material for laboratory techniques (such as filtration and precipitation) to work. Like iodine, astatine has been shown to adopt odd-numbered oxidation states ranging from −1 to +7. Only a few compounds with metals have been reported, in the form of astatides of sodium, palladium, silver, thallium, and lead. Some characteristic properties of silver and sodium astatide, and the other hypothetical alkali and alkaline earth astatides, have been estimated by extrapolation from other metal halides. The formation of an astatine compound with hydrogen – usually referred to as hydrogen astatide – was noted by the pioneers of astatine chemistry. As mentioned, there are grounds for instead referring to this compound as astatine hydride. It is easily oxidized; acidification by dilute nitric acid gives the At0 or At+ forms, and the subsequent addition of silver(I) may only partially, at best, precipitate astatine as silver(I) astatide (AgAt). Iodine, in contrast, is not oxidized, and precipitates readily as silver(I) iodide. Astatine is known to bind to boron, carbon, and nitrogen. Various boron cage compounds have been prepared with At–B bonds, these being more stable than At–C bonds. Astatine can replace a hydrogen atom in benzene to form astatobenzene C6H5At; this may be oxidized to C6H5AtCl2 by chlorine. By treating this compound with an alkaline solution of hypochlorite, C6H5AtO2 can be produced. The dipyridine-astatine(I) cation, [At(C5H5N)2]+, forms ionic compounds with perchlorate (a non-coordinating anion) and with nitrate, [At(C5H5N)2]NO3. This cation exists as a coordination complex in which two dative covalent bonds separately link the astatine(I) centre with each of the pyridine rings via their nitrogen atoms. With oxygen, there is evidence of the species AtO− and AtO+ in aqueous solution, formed by the reaction of astatine with an oxidant such as elemental bromine or (in the last case) by sodium persulfate in a solution of perchloric acid: the latter species might also be protonated astatous acid, . The species previously thought to be has since been determined to be , a hydrolysis product of AtO+ (another such hydrolysis product being AtOOH). The well characterized anion can be obtained by, for example, the oxidation of astatine with potassium hypochlorite in a solution of potassium hydroxide. Preparation of lanthanum triastatate La(AtO3)3, following the oxidation of astatine by a hot Na2S2O8 solution, has been reported. Further oxidation of , such as by xenon difluoride (in a hot alkaline solution) or periodate (in a neutral or alkaline solution), yields the perastatate ion ; this is only stable in neutral or alkaline solutions. Astatine is also thought to be capable of forming cations in salts with oxyanions such as iodate or dichromate; this is based on the observation that, in acidic solutions, monovalent or intermediate positive states of astatine coprecipitate with the insoluble salts of metal cations such as silver(I) iodate or thallium(I) dichromate. Astatine may form bonds to the other chalcogens; these include S7At+ and with sulfur, a coordination selenourea compound with selenium, and an astatine–tellurium colloid with tellurium. Astatine is known to react with its lighter homologs iodine, bromine, and chlorine in the vapor state; these reactions produce diatomic interhalogen compounds with formulas AtI, AtBr, and AtCl. The first two compounds may also be produced in water – astatine reacts with iodine/iodide solution to form AtI, whereas AtBr requires (aside from astatine) an iodine/iodine monobromide/bromide solution. The excess of iodides or bromides may lead to and ions, or in a chloride solution, they may produce species like or via equilibrium reactions with the chlorides. Oxidation of the element with dichromate (in nitric acid solution) showed that adding chloride turned the astatine into a molecule likely to be either AtCl or AtOCl. Similarly, or may be produced. The polyhalides PdAtI2, CsAtI2, TlAtI2, and PbAtI are known or presumed to have been precipitated. In a plasma ion source mass spectrometer, the ions [AtI]+, [AtBr]+, and [AtCl]+ have been formed by introducing lighter halogen vapors into a helium-filled cell containing astatine, supporting the existence of stable neutral molecules in the plasma ion state. No astatine fluorides have been discovered yet. Their absence has been speculatively attributed to the extreme reactivity of such compounds, including the reaction of an initially formed fluoride with the walls of the glass container to form a non-volatile product. Thus, although the synthesis of an astatine fluoride is thought to be possible, it may require a liquid halogen fluoride solvent, as has already been used for the characterization of radon fluoride. History In 1869, when Dmitri Mendeleev published his periodic table, the space under iodine was empty; after Niels Bohr established the physical basis of the classification of chemical elements, it was suggested that the fifth halogen belonged there. Before its officially recognized discovery, it was called "eka-iodine" (from Sanskrit eka – "one") to imply it was one space under iodine (in the same manner as eka-silicon, eka-boron, and others). Scientists tried to find it in nature; given its extreme rarity, these attempts resulted in several false discoveries. The first claimed discovery of eka-iodine was made by Fred Allison and his associates at the Alabama Polytechnic Institute (now Auburn University) in 1931. The discoverers named element 85 "alabamine", and assigned it the symbol Ab, designations that were used for a few years. In 1934, H. G. MacPherson of University of California, Berkeley disproved Allison's method and the validity of his discovery. There was another claim in 1937, by the chemist Rajendralal De. Working in Dacca in British India (now Dhaka in Bangladesh), he chose the name "dakin" for element 85, which he claimed to have isolated as the thorium series equivalent of radium F (polonium-210) in the radium series. The properties he reported for dakin do not correspond to those of astatine, and astatine's radioactivity would have prevented him from handling it in the quantities he claimed. Moreover, astatine is not found in the thorium series, and the true identity of dakin is not known. In 1936, the team of Romanian physicist Horia Hulubei and French physicist Yvette Cauchois claimed to have discovered element 85 by observing its X-ray emission lines. In 1939, they published another paper which supported and extended previous data. In 1944, Hulubei published a summary of data he had obtained up to that time, claiming it was supported by the work of other researchers. He chose the name "dor", presumably from the Romanian for "longing" [for peace], as World War II had started five years earlier. As Hulubei was writing in French, a language which does not accommodate the "ine" suffix, dor would likely have been rendered in English as "dorine", had it been adopted. In 1947, Hulubei's claim was effectively rejected by the Austrian chemist Friedrich Paneth, who would later chair the IUPAC committee responsible for recognition of new elements. Even though Hulubei's samples did contain astatine-218, his means to detect it were too weak, by current standards, to enable correct identification; moreover, he could not perform chemical tests on the element. He had also been involved in an earlier false claim as to the discovery of element 87 (francium) and this is thought to have caused other researchers to downplay his work. In 1940, the Swiss chemist Walter Minder announced the discovery of element 85 as the beta decay product of radium A (polonium-218), choosing the name "helvetium" (from , the Latin name of Switzerland). Berta Karlik and Traude Bernert were unsuccessful in reproducing his experiments, and subsequently attributed Minder's results to contamination of his radon stream (radon-222 is the parent isotope of polonium-218). In 1942, Minder, in collaboration with the English scientist Alice Leigh-Smith, announced the discovery of another isotope of element 85, presumed to be the product of thorium A (polonium-216) beta decay. They named this substance "anglo-helvetium", but Karlik and Bernert were again unable to reproduce these results. Later in 1940, Dale R. Corson, Kenneth Ross MacKenzie, and Emilio Segrè isolated the element at the University of California, Berkeley. Instead of searching for the element in nature, the scientists created it by bombarding bismuth-209 with alpha particles in a cyclotron (particle accelerator) to produce, after emission of two neutrons, astatine-211. The discoverers, however, did not immediately suggest a name for the element. The reason for this was that at the time, an element created synthetically in "invisible quantities" that had not yet been discovered in nature was not seen as a completely valid one; in addition, chemists were reluctant to recognize radioactive isotopes as legitimately as stable ones. In 1943, astatine was found as a product of two naturally occurring decay chains by Berta Karlik and Traude Bernert, first in the so-called uranium series, and then in the actinium series. (Since then, astatine was also found in a third decay chain, the neptunium series.) Friedrich Paneth in 1946 called to finally recognize synthetic elements, quoting, among other reasons, recent confirmation of their natural occurrence, and proposed that the discoverers of the newly discovered unnamed elements name these elements. In early 1947, Nature published the discoverers' suggestions; a letter from Corson, MacKenzie, and Segrè suggested the name "astatine" coming from the Greek astatos (αστατος) meaning "unstable", because of its propensity for radioactive decay, with the ending "-ine", found in the names of the four previously discovered halogens. The name was also chosen to continue the tradition of the four stable halogens, where the name referred to a property of the element. Corson and his colleagues classified astatine as a metal on the basis of its analytical chemistry. Subsequent investigators reported iodine-like, cationic, or amphoteric behavior. In a 2003 retrospective, Corson wrote that "some of the properties [of astatine] are similar to iodine … it also exhibits metallic properties, more like its metallic neighbors Po and Bi." Isotopes There are 39 known isotopes of astatine, with atomic masses (mass numbers) of 191–229. Theoretical modeling suggests that 37 more isotopes could exist. No stable or long-lived astatine isotope has been observed, nor is one expected to exist. Astatine's alpha decay energies follow the same trend as for other heavy elements. Lighter astatine isotopes have quite high energies of alpha decay, which become lower as the nuclei become heavier. Astatine-211 has a significantly higher energy than the previous isotope, because it has a nucleus with 126 neutrons, and 126 is a magic number corresponding to a filled neutron shell. Despite having a similar half-life to the previous isotope (8.1 hours for astatine-210 and 7.2 hours for astatine-211), the alpha decay probability is much higher for the latter: 41.81% against only 0.18%. The two following isotopes release even more energy, with astatine-213 releasing the most energy. For this reason, it is the shortest-lived astatine isotope. Even though heavier astatine isotopes release less energy, no long-lived astatine isotope exists, because of the increasing role of beta decay (electron emission). This decay mode is especially important for astatine; as early as 1950 it was postulated that all isotopes of the element undergo beta decay, though nuclear mass measurements indicate that 215At is in fact beta-stable, as it has the lowest mass of all isobars with A = 215. A beta decay mode has been found for all other astatine isotopes except for astatine-213, astatine-214, and astatine-216m. Astatine-210 and lighter isotopes exhibit beta plus decay (positron emission), astatine-216 and heavier isotopes exhibit beta minus decay, and astatine-212 decays via both modes, while astatine-211 undergoes electron capture. The most stable isotope is astatine-210, which has a half-life of 8.1 hours. The primary decay mode is beta plus, to the relatively long-lived (in comparison to astatine isotopes) alpha emitter polonium-210. In total, only five isotopes have half-lives exceeding one hour (astatine-207 to -211). The least stable ground state isotope is astatine-213, with a half-life of 125 nanoseconds. It undergoes alpha decay to the extremely long-lived bismuth-209. Astatine has 24 known nuclear isomers, which are nuclei with one or more nucleons (protons or neutrons) in an excited state. A nuclear isomer may also be called a "meta-state", meaning the system has more internal energy than the "ground state" (the state with the lowest possible internal energy), making the former likely to decay into the latter. There may be more than one isomer for each isotope. The most stable of these nuclear isomers is astatine-202m1, which has a half-life of about 3 minutes, longer than those of all the ground states bar those of isotopes 203–211 and 220. The least stable is astatine-214m1; its half-life of 265 nanoseconds is shorter than those of all ground states except that of astatine-213. Natural occurrence Astatine is the rarest naturally occurring element. The total amount of astatine in the Earth's crust (quoted mass 2.36 × 1025 grams) is estimated by some to be less than one gram at any given time. Other sources estimate the amount of ephemeral astatine, present on earth at any given moment, to be up to one ounce (about 28 grams). Any astatine present at the formation of the Earth has long since disappeared; the four naturally occurring isotopes (astatine-215, -217, -218 and -219) are instead continuously produced as a result of the decay of radioactive thorium and uranium ores, and trace quantities of neptunium-237. The landmass of North and South America combined, to a depth of 16 kilometers (10 miles), contains only about one trillion astatine-215 atoms at any given time (around 3.5 × 10−10 grams). Astatine-217 is produced via the radioactive decay of neptunium-237. Primordial remnants of the latter isotope—due to its relatively short half-life of 2.14 million years—are no longer present on Earth. However, trace amounts occur naturally as a product of transmutation reactions in uranium ores. Astatine-218 was the first astatine isotope discovered in nature. Astatine-219, with a half-life of 56 seconds, is the longest lived of the naturally occurring isotopes. Isotopes of astatine are sometimes not listed as naturally occurring because of misconceptions that there are no such isotopes, or discrepancies in the literature. Astatine-216 has been counted as a naturally occurring isotope but reports of its observation (which were described as doubtful) have not been confirmed. Synthesis Formation Astatine was first produced by bombarding bismuth-209 with energetic alpha particles, and this is still the major route used to create the relatively long-lived isotopes astatine-209 through astatine-211. Astatine is only produced in minuscule quantities, with modern techniques allowing production runs of up to 6.6 giga becquerels (about 86 nanograms or 2.47 × 1014 atoms). Synthesis of greater quantities of astatine using this method is constrained by the limited availability of suitable cyclotrons and the prospect of melting the target. Solvent radiolysis due to the cumulative effect of astatine decay is a related problem. With cryogenic technology, microgram quantities of astatine might be able to be generated via proton irradiation of thorium or uranium to yield radon-211, in turn decaying to astatine-211. Contamination with astatine-210 is expected to be a drawback of this method. The most important isotope is astatine-211, the only one in commercial use. To produce the bismuth target, the metal is sputtered onto a gold, copper, or aluminium surface at 50 to 100 milligrams per square centimeter. Bismuth oxide can be used instead; this is forcibly fused with a copper plate. The target is kept under a chemically neutral nitrogen atmosphere, and is cooled with water to prevent premature astatine vaporization. In a particle accelerator, such as a cyclotron, alpha particles are collided with the bismuth. Even though only one bismuth isotope is used (bismuth-209), the reaction may occur in three possible ways, producing astatine-209, astatine-210, or astatine-211. In order to eliminate undesired nuclides, the maximum energy of the particle accelerator is set to a value (optimally 29.17 MeV) above that for the reaction producing astatine-211 (to produce the desired isotope) and below the one producing astatine-210 (to avoid producing other astatine isotopes). Separation methods Since astatine is the main product of the synthesis, after its formation it must only be separated from the target and any significant contaminants. Several methods are available, "but they generally follow one of two approaches—dry distillation or [wet] acid treatment of the target followed by solvent extraction." The methods summarized below are modern adaptations of older procedures, as reviewed by Kugler and Keller. Pre-1985 techniques more often addressed the elimination of co-produced toxic polonium; this requirement is now mitigated by capping the energy of the cyclotron irradiation beam. Dry The astatine-containing cyclotron target is heated to a temperature of around 650 °C. The astatine volatilizes and is condensed in (typically) a cold trap. Higher temperatures of up to around 850 °C may increase the yield, at the risk of bismuth contamination from concurrent volatilization. Redistilling the condensate may be required to minimize the presence of bismuth (as bismuth can interfere with astatine labeling reactions). The astatine is recovered from the trap using one or more low concentration solvents such as sodium hydroxide, methanol or chloroform. Astatine yields of up to around 80% may be achieved. Dry separation is the method most commonly used to produce a chemically useful form of astatine. Wet The irradiated bismuth (or sometimes bismuth trioxide) target is first dissolved in, for example, concentrated nitric or perchloric acid. Following this first step, the acid can be distilled away to leave behind a white residue that contains both bismuth and the desired astatine product. This residue is then dissolved in a concentrated acid, such as hydrochloric acid. Astatine is extracted from this acid using an organic solvent such as butyl or isopropyl ether, diisopropylether (DIPE), or thiosemicarbazide. Using liquid-liquid extraction, the astatine product can be repeatedly washed with an acid, such as HCl, and extracted into the organic solvent layer. A separation yield of 93% using nitric acid has been reported, falling to 72% by the time purification procedures were completed (distillation of nitric acid, purging residual nitrogen oxides, and redissolving bismuth nitrate to enable liquid–liquid extraction). Wet methods involve "multiple radioactivity handling steps" and have not been considered well suited for isolating larger quantities of astatine. However, wet extraction methods are being examined for use in production of larger quantities of astatine-211, as it is thought that wet extraction methods can provide more consistency. They can enable the production of astatine in a specific oxidation state and may have greater applicability in experimental radiochemistry.

It must be used quickly as it decays with a half-life of 7.2 hours; this is long enough to permit multistep labeling strategies. Astatine-211 has potential for targeted alpha-particle therapy, since it decays either via emission of an alpha particle (to bismuth-207), or via electron capture (to an extremely short-lived nuclide, polonium-211, which undergoes further alpha decay), very quickly reaching its stable granddaughter lead-207. Polonium X-rays emitted as a result of the electron capture branch, in the range of 77–92 keV, enable the tracking of astatine in animals and patients. Although astatine-210 has a slightly longer half-life, it is wholly unsuitable because it usually undergoes beta plus decay to the extremely toxic polonium-210. The principal medicinal difference between astatine-211 and iodine-131 (a radioactive iodine isotope also used in medicine) is that iodine-131 emits high-energy beta particles, and astatine does not. Beta particles have much greater penetrating power through tissues than do the much heavier alpha particles. An average alpha particle released by astatine-211 can travel up to 70 µm through surrounding tissues; an average-energy beta particle emitted by iodine-131 can travel nearly 30 times as far, to about 2 mm. The short half-life and limited penetrating power of alpha radiation through tissues offers advantages in situations where the "tumor burden is low and/or malignant cell populations are located in close proximity to essential normal tissues." Significant morbidity in cell culture models of human cancers has been achieved with from one to ten astatine-211 atoms bound per cell. Several obstacles have been encountered in the development of astatine-based radiopharmaceuticals for cancer treatment. World War II delayed research for close to a decade. Results of early experiments indicated that a cancer-selective carrier would need to be developed and it was not until the 1970s that monoclonal antibodies became available for this purpose. Unlike iodine, astatine shows a tendency to dehalogenate from molecular carriers such as these, particularly at sp3 carbon sites (less so from sp2 sites). Given the toxicity of astatine accumulated and retained in the body, this emphasized the need to ensure it remained attached to its host molecule. While astatine carriers that are slowly metabolized can be assessed for their efficacy, more rapidly metabolized carriers remain a significant obstacle to the evaluation of astatine in nuclear medicine. Mitigating the effects of astatine-induced radiolysis of labeling chemistry and carrier molecules is another area requiring further development. A practical application for astatine as a cancer treatment would potentially be suitable for a "staggering" number of patients; production of astatine in the quantities that would be required remains an issue. Animal studies show that astatine, similarly to iodine—although to a lesser extent, perhaps because of its slightly more metallic nature—is preferentially (and dangerously) concentrated in the thyroid gland. Unlike iodine, astatine also shows a tendency to be taken up by the lungs and spleen, possibly because of in-body oxidation of At– to At+. If administered in the form of a radiocolloid it tends to concentrate in the liver. Experiments in rats and monkeys suggest that astatine-211 causes much greater damage to the thyroid gland than does iodine-131, with repetitive injection of the nuclide resulting in necrosis and cell dysplasia within the gland. Early research suggested that injection of astatine into female rodents caused morphological changes in breast tissue; this conclusion remained controversial for many years. General agreement was later reached that this was likely caused by the effect of breast tissue irradiation combined with hormonal changes due to irradiation of the ovaries. Trace amounts of astatine can be handled safely in fume hoods if they are well-aerated; biological uptake of the element must be avoided.

Arable land

Arable land (from the , "able to be ploughed") is any land capable of being ploughed and used to grow crops. Alternatively, for the purposes of agricultural statistics, the term often has a more precise definition: A more concise definition appearing in the Eurostat glossary similarly refers to actual rather than potential uses: "land worked (ploughed or tilled) regularly, generally under a system of crop rotation".In Britain, arable land has traditionally been contrasted with pasturable land such as heaths, which could be used for sheep-rearing but not as farmland. Arable land is vulnerable to land degradation and some types of un-arable land can be enriched to create useful land. Climate change and biodiversity loss, are driving pressure on arable land. By country According to the Food and Agriculture Organization of the United Nations, in 2013, the world's arable land amounted to 1.407 billion hectares, out of a total of 4.924 billion hectares of land used for agriculture. Arable land (hectares per person) Non-arable land Agricultural land that is not arable according to the FAO definition above includes: Meadows and pasturesland used as pasture and grazed range, and those natural grasslands and sedge meadows that are used for hay production in some regions. Permanent cropland that produces crops from woody vegetation, e.g. orchard land, vineyards, coffee plantations, rubber plantations, and land producing nut trees; Other non-arable land includes land that is not suitable for any agricultural use. Land that is not arable, in the sense of lacking capability or suitability for cultivation for crop production, has one or more limitationsa lack of sufficient freshwater for irrigation, stoniness, steepness, adverse climate, excessive wetness with the impracticality of drainage, excessive salts, or a combination of these, among others. Although such limitations may preclude cultivation, and some will in some cases preclude any agricultural use, large areas unsuitable for cultivation may still be agriculturally productive. For example, United States NRCS statistics indicate that about 59 percent of US non-federal pasture and unforested rangeland is unsuitable for cultivation, yet such land has value for grazing of livestock. In British Columbia, Canada, 41 percent of the provincial Agricultural Land Reserve area is unsuitable for the production of cultivated crops, but is suitable for uncultivated production of forage usable by grazing livestock. Similar examples can be found in many rangeland areas elsewhere. Changes in arability Land conversion Land incapable of being cultivated for the production of crops can sometimes be converted to arable land. New arable land makes more food and can reduce starvation. This outcome also makes a country more self-sufficient and politically independent, because food importation is reduced. Making non-arable land arable often involves digging new irrigation canals and new wells, aqueducts, desalination plants, planting trees for shade in the desert, hydroponics, fertilizer, nitrogen fertilizer, pesticides, reverse osmosis water processors, PET film insulation or other insulation against heat and cold, digging ditches and hills for protection against the wind, and installing greenhouses with internal light and heat for protection against the cold outside and to provide light in cloudy areas. Such modifications are often prohibitively expensive. An alternative is the seawater greenhouse, which desalinates water through evaporation and condensation using solar energy as the only energy input. This technology is optimized to grow crops on desert land close to the sea. The use of artifices does not make the land arable. Rock still remains rock, and shallowless than turnable soil is still not considered toilable. The use of artifice is an open-air none recycled water hydroponics relationship. The below described circumstances are not in perspective, have limited duration, and have a tendency to accumulate trace materials in soil that either there or elsewhere cause deoxygenation. The use of vast amounts of fertilizer may have unintended consequences for the environment by devastating rivers, waterways, and river endings through the accumulation of non-degradable toxins and nitrogen-bearing molecules that remove oxygen and cause non-aerobic processes to form. Examples of infertile non-arable land being turned into fertile arable land include: Aran Islands: These islands off the west coast of Ireland (not to be confused with the Isle of Arran in Scotland's Firth of Clyde) were unsuitable for arable farming because they were too rocky. The people covered the islands with a shallow layer of seaweed and sand from the ocean. Today, crops are grown there, even though the islands are still considered non-arable. Israel: The construction of desalination plants along Israel's coast allowed agriculture in some areas that were formerly desert. The desalination plants, which remove the salt from ocean water, have produced a new source of water for farming, drinking, and washing. Slash and burn agriculture uses nutrients in wood ash, but these expire within a few years. Terra preta, fertile tropical soils produced by adding charcoal. Land degradation Examples Examples of fertile arable land being turned into infertile land include: Droughts such as the "Dust Bowl" of the Great Depression in the US turned farmland into desert. Each year, arable land is lost due to desertification and human-induced erosion. Improper irrigation of farmland can wick the sodium, calcium, and magnesium from the soil and water to the surface. This process steadily concentrates salt in the root zone, decreasing productivity for crops that are not salt-tolerant. Rainforest deforestation: The fertile tropical forests are converted into infertile desert land. For example, Madagascar's central highland plateau has become virtually totally barren (about ten percent of the country) as a result of slash-and-burn deforestation, an element of shifting cultivation practiced by many natives.

Author

An author is the writer of a book, article, play, or other written work. A broader definition of the word "author" states: "An author is 'the person who originated or gave existence to anything" and whose authorship determines responsibility for what was created.'" Typically, the first owner of a copyright is the person who created the work, i.e. the author. If more than one person created the work (i.e., multiple authors), then a case of joint authorship takes place. Copyright laws differ around the world. The United States Copyright Office, for example, defines copyright as "a form of protection provided by the laws of the United States (title 17, U.S. Code) to authors of 'original works of authorship.'" Legal significance of authorship Holding the title of "author" over any "literary, dramatic, musical, artistic, [or] certain other intellectual works" gives rights to this person, the owner of the copyright, especially the exclusive right to engage in or authorize any production or distribution of their work. Any person or entity wishing to use intellectual property held under copyright must receive permission from the copyright holder to use this work, and often will be asked to pay for the use of copyrighted material. The copyrights on intellectual work expire after a certain time and it enters the public domain, where it can be used without limit. Copyright laws in many jurisdictions – mostly following the lead of the United States, in which the entertainment and publishing industries have very strong lobbying power – have been amended repeatedly since their inception, to extend the length of this fixed period where the work is exclusively controlled by the copyright holder. Technically, someone owns their work from the time it's created. A notable aspect of authorship emerges with copyright in that, in many jurisdictions, it can be passed down to another upon one's death. The person who inherits the copyright is not the author, but has access to the same legal benefits. Intellectual property laws are complex. Fiction work involves trademark law, likeness rights, fair use rights held by the public (including the right to parody or satirize), and many other interacting complications. Authors may portion out different rights they hold to different parties, at different times, and for different purposes or uses, such as the right to adapt a plot into a film, but only with different character names, because the characters have already been optioned by another company for a television series or a video game. An author may also not have rights when working under contract that they would otherwise have, such as when creating a work for hire (e.g., hired to write a city tour guide by a municipal government that totally owns the copyright to the finished work), or when writing material using intellectual property owned by others (such as when writing a novel or screenplay that is a new installment in an already established media franchise). Philosophical views of the nature of authorship In literary theory, critics find complications in the term author beyond what constitutes authorship in a legal setting. In the wake of postmodern literature, critics such as Roland Barthes and Michel Foucault have examined the role and relevance of authorship to the meaning or interpretation of a text. Barthes challenges the idea that a text can be attributed to any single author. He writes, in his essay "Death of the Author" (1968), that "it is language which speaks, not the author." The words and language of a text itself determine and expose meaning for Barthes, and not someone possessing legal responsibility for the process of its production. Every line of written text is a mere reflection of references from any of a multitude of traditions, or, as Barthes puts it, "the text is a tissue of quotations drawn from the innumerable centers of culture"; it is never original. With this, the perspective of the author is removed from the text, and the limits formerly imposed by the idea of one authorial voice, one ultimate and universal meaning, are destroyed. The explanation and meaning of a work does not have to be sought in the one who produced it, "as if it were always in the end, through the more or less transparent allegory of the fiction, the voice of a single person, the author 'confiding' in us." The psyche, culture, fanaticism of an author can be disregarded when interpreting a text, because the words are rich enough themselves with all of the traditions of language. To expose meanings in a written work without appealing to the celebrity of an author, their tastes, passions, vices, is, to Barthes, to allow language to speak, rather than author. Michel Foucault argues in his essay "What is an author?" (1969) that all authors are writers, but not all writers are authors. He states that "a private letter may have a signatory—it does not have an author." For a reader to assign the title of author upon any written work is to attribute certain standards upon the text which, for Foucault, are working in conjunction with the idea of "the author function." Foucault's author function is the idea that an author exists only as a function of a written work, a part of its structure, but not necessarily part of the interpretive process. The author's name "indicates the status of the discourse within a society and culture," and at one time was used as an anchor for interpreting a text, a practice which Barthes would argue is not a particularly relevant or valid endeavour. Expanding upon Foucault's position, Alexander Nehamas writes that Foucault suggests "an author [...] is whoever can be understood to have produced a particular text as we interpret it," not necessarily who penned the text. It is this distinction between producing a written work and producing the interpretation or meaning in a written work that both Barthes and Foucault are interested in. Foucault warns of the risks of keeping the author's name in mind during interpretation, because it could affect the value and meaning with which one handles an interpretation. Literary critics Barthes and Foucault suggest that readers should not rely on or look for the notion of one overarching voice when interpreting a written work, because of the complications inherent with a writer's title of "author." They warn of the dangers interpretations could suffer from when associating the subject of inherently meaningful words and language with the personality of one authorial voice. Instead, readers should allow a text to be interpreted in terms of the language as "author." Relationship with publisher Self-publishing Self-publishing is a model where the author takes full responsibility and control of arranging financing, editing, printing, and distribution of their own work. In other words, the author also acts as the publisher of their work. Traditional publishing With commissioned publishing, the publisher makes all the publication arrangements and the author covers all expenses. The author of a work may receive a percentage calculated on a wholesale or a specific price or a fixed amount on each book sold. Publishers, at times, reduced the risk of this type of arrangement, by agreeing only to pay this after a certain number of copies had sold. In Canada, this practice occurred during the 1890s, but was not commonplace until the 1920s. Established and successful authors may receive advance payments, set against future royalties, but this is no longer common practice. Most independent publishers pay royalties as a percentage of net receipts – how net receipts are calculated varies from publisher to publisher. Under this arrangement, the author does not pay anything towards the expense of publication. The costs and financial risk are all carried by the publisher, who will then take the greatest percentage of the receipts. See Compensation for more. Vanity publishing This type of publisher normally charges a flat fee for arranging publication, offers a platform for selling, and then takes a percentage of the sale of every copy of a book. The author receives the rest of the money made. Relationship with editor The relationship between the author and the editor, often the author's only liaison to the publishing company, is often characterized as the site of tension. For the author to reach their audience, often through publication, the work usually must attract the attention of the editor. The idea of the author as the sole meaning-maker of necessity changes to include the influences of the editor and the publisher to engage the audience in writing as a social act. There are three principal areas covered by editors – Proofing (checking the Grammar and spelling, looking for typing errors), Story (potentially an area of deep angst for both author and publisher), and Layout (the setting of the final proof ready for publishing often requires minor text changes so a layout editor is required to ensure that these do not alter the sense of the text). Pierre Bourdieu's essay "The Field of Cultural Production" depicts the publishing industry as a "space of literary or artistic position-takings," also called the "field of struggles," which is defined by the tension and movement inherent among the various positions in the field. Bourdieu claims that the "field of position-takings [...] is not the product of coherence-seeking intention or objective consensus," meaning that an industry characterized by position-takings is not one of harmony and neutrality. In particular for the writer, their authorship in their work makes their work part of their identity, and there is much at stake personally over the negotiation of authority over that identity. However, it is the editor who has "the power to impose the dominant definition of the writer and therefore to delimit the population of those entitled to take part in the struggle to define the writer". As "cultural investors," publishers rely on the editor position to identify a good investment in "cultural capital" which may grow to yield economic capital across all positions. According to the studies of James Curran, the system of shared values among editors in Britain has generated a pressure among authors to write to fit the editors' expectations, removing the focus from the reader-audience and putting a strain on the relationship between authors and editors and on writing as a social act. Even the book review by the editors has more significance than the readership's reception. Compensation Authors rely on advance fees, royalty payments, adaptation of work to a screenplay, and fees collected from giving speeches. A standard contract for an author will usually include provision for payment in the form of an advance and royalties. An advance is a lump sum paid in advance of publication. An advance must be earned out before royalties are payable. An advance may be paid in two lump sums: the first payment on contract signing, and the second on delivery of the completed manuscript or on publication. Royalty payment is the sum paid to authors for each copy of a book sold and is traditionally around 10–12%, but self-published authors can earn about 40% – 60% royalties per each book sale. An author's contract may specify, for example, that they will earn 10% of the retail price of each book sold. Some contracts specify a scale of royalties payable (for example, where royalties start at 10% for the first 10,000 sales, but then increase to a higher percentage rate at higher sale thresholds). An author's book must earn the advance before any further royalties are paid. For example, if an author is paid a modest advance of $2000, and their royalty rate is 10% of a book priced at $20 – that is, $2 per book – the book will need to sell 1000 copies before any further payment will be made. Publishers typically withhold payment of a percentage of royalties earned against returns. In some countries, authors also earn income from a government scheme such as the ELR (educational lending right) and PLR (public lending right) schemes in Australia. Under these schemes, authors are paid a fee for the number of copies of their books in educational and/or public libraries. These days, many authors supplement their income from book sales with public speaking engagements, school visits, residencies, grants, and teaching positions. Ghostwriters, technical writers, and textbooks writers are typically paid in a different way: usually a set fee or a per word rate rather than on a percentage of sales. In the year 2016, according to the U.S. Bureau of Labor Statistics, nearly 130,000 people worked in the U.S. as authors making an average of $61,240 per year.

A. A. Milne

Alan Alexander Milne (; 18 January 1882 – 31 January 1956) was an English writer best known for his books about the teddy bear Winnie-the-Pooh, as well as for children's poetry. Milne was primarily a playwright before the huge success of Winnie-the-Pooh overshadowed all his previous work. Milne served in both World Wars, as a lieutenant in the Royal Warwickshire Regiment in the First World War and as a captain in the Home Guard in the Second World War. Milne was the father of bookseller Christopher Robin Milne, upon whom the character Christopher Robin is based. It was during a visit to London Zoo, where Christopher became enamoured with the tame and amiable bear Winnipeg, that Milne was inspired to write the story of Winnie-the-Pooh for his son. Early life and military career Alan Alexander Milne was born in Kilburn, London, to John Vine Milne, who was born in Jamaica, and Sarah Marie Milne (née Heginbotham), on 18 January 1882. He grew up at Henley House School, 6/7 Mortimer Road (now Crescent), Kilburn, a small independent school run by his father. One of his teachers was H. G. Wells, who taught there in 1889–90. Milne attended Westminster School and Trinity College, Cambridge, where he studied on a mathematics scholarship, graduating with a B.A. in Mathematics in 1903. He edited and wrote for Granta, a student magazine. He collaborated with his brother Kenneth and their articles appeared over the initials AKM. Milne's work came to the attention of the leading British humour magazine Punch, where Milne was to become a contributor and later an assistant editor. Considered a talented cricket fielder, Milne played for two amateur teams that were largely composed of British writers: the Allahakbarries and the Authors XI. His teammates included fellow writers J. M. Barrie, Arthur Conan Doyle and P. G. Wodehouse. Milne joined the British Army in World War I and served as an officer in the Royal Warwickshire Regiment. He was commissioned into the 4th Battalion, Royal Warwickshire Regiment, on 1 February 1915 as a second lieutenant (on probation). His commission was confirmed on 20 December 1915. He served on the Somme as a signals officer from July-November 1916, but caught trench fever and was invalided back to England. Having recuperated, he worked as a signals instructor, before being recruited into Military Intelligence to write propaganda articles for MI7 (b) between 1917 and 1918. He was discharged on 14 February 1919, and settled in Mallord Street, Chelsea. He relinquished his commission on 19 February 1920, retaining the rank of lieutenant. After the war, he wrote a denunciation of war titled Peace with Honour (1934), which he retracted somewhat with 1940's War with Honour. During World War II, Milne was one of the most prominent critics of fellow English writer (and Authors XI cricket teammate) P. G. Wodehouse, who was captured at his country home in France by the Nazis and imprisoned for a year. Wodehouse made radio broadcasts about his internment, which were broadcast from Berlin. Although the light-hearted broadcasts made fun of the Germans, Milne accused Wodehouse of committing an act of near treason by cooperating with his country's enemy. Wodehouse got some revenge on his former friend (e.g. in The Mating Season) by creating fatuous parodies of the Christopher Robin poems in some of his later stories, and claiming that Milne "was probably jealous of all other writers.... But I loved his stuff." Milne married Dorothy "Daphne" de Sélincourt (1890–1971) in 1913 and their son Christopher Robin Milne was born in 1920. In 1925, Milne bought a country home, Cotchford Farm, in Hartfield, East Sussex. During World War II, Milne was a captain in the British Home Guard in Hartfield & Forest Row, insisting on being plain "Mr. Milne" to the members of his platoon. He retired to the farm after a stroke and brain surgery in 1952 left him an invalid, and by August 1953, "he seemed very old and disenchanted." Milne died in January 1956, aged 74. Literary career 1903 to 1925 After graduating from Cambridge University in 1903, A. A. Milne contributed humorous verse and whimsical essays to Punch, joining the staff in 1906 and becoming an assistant editor. During this period he published 18 plays and three novels, including the murder mystery The Red House Mystery (1922). His son was born in August 1920 and in 1924 Milne produced a collection of children's poems, When We Were Very Young, which were illustrated by Punch staff cartoonist E. H. Shepard. A collection of short stories for children A Gallery of Children, and other stories that became part of the Winnie-the-Pooh books, were first published in 1925. Milne was an early screenwriter for the nascent British film industry, writing four stories filmed in 1920 for the company Minerva Films (founded in 1920 by the actor Leslie Howard and his friend and story editor Adrian Brunel). These were The Bump, starring Aubrey Smith; Twice Two; Five Pound Reward; and Bookworms. Some of these films survive in the archives of the British Film Institute. Milne had met Howard when the actor starred in Milne's play Mr Pim Passes By in London. Looking back on this period (in 1926), Milne observed that when he told his agent that he was going to write a detective story, he was told that what the country wanted from a "Punch humorist" was a humorous story; when two years later he said he was writing nursery rhymes, his agent and publisher were convinced he should write another detective story; and after another two years, he was being told that writing a detective story would be in the worst of taste given the demand for children's books. He concluded that "the only excuse which I have yet discovered for writing anything is that I want to write it; and I should be as proud to be delivered of a Telephone Directory con amore as I should be ashamed to create a Blank Verse Tragedy at the bidding of others." 1926 to 1928 Milne is most famous for his two Pooh books about a boy named Christopher Robin after his son, Christopher Robin Milne (1920–1996), and various characters inspired by his son's stuffed animals, most notably the bear named Winnie-the-Pooh. Christopher Robin Milne's stuffed bear, originally named Edward, was renamed Winnie after a Canadian black bear named Winnie (after Winnipeg), which was used as a military mascot in World War I, and left to London Zoo during the war. "The Pooh" comes from a swan the young Milne named "Pooh". E. H. Shepard illustrated the original Pooh books, using his own son's teddy Growler ("a magnificent bear") as the model. The rest of Christopher Robin Milne's toys, Piglet, Eeyore, Kanga, Roo and Tigger, were incorporated into A. A. Milne's stories, and two more characters – Rabbit and Owl – were created by Milne's imagination. Christopher Robin Milne's own toys are now on display in New York where 750,000 people visit them every year. The fictional Hundred Acre Wood of the Pooh stories derives from Five Hundred Acre Wood in Ashdown Forest in East Sussex, South East England, where the Pooh stories were set. Milne lived on the northern edge of the forest at Cotchford Farm, , and took his son walking there. E. H. Shepard drew on the landscapes of Ashdown Forest as inspiration for many of the illustrations he provided for the Pooh books. The adult Christopher Robin commented: "Pooh's Forest and Ashdown Forest are identical." Popular tourist locations at Ashdown Forest include: Galleon's Lap, The Enchanted Place, the Heffalump Trap and Lone Pine, Eeyore’s Sad and Gloomy Place, and the wooden Pooh Bridge where Pooh and Piglet invented Poohsticks. Not yet known as Pooh, he made his first appearance in a poem, "Teddy Bear", published in Punch magazine in February 1924 and republished that year in When We Were Very Young. Pooh first appeared in the London Evening News on Christmas Eve, 1925, in a story called "The Wrong Sort of Bees". Winnie-the-Pooh was published in 1926, followed by The House at Pooh Corner in 1928. A second collection of nursery rhymes, Now We Are Six, was published in 1927. All four books were illustrated by E. H. Shepard. Milne also published four plays in this period. He also "gallantly stepped forward" to contribute a quarter of the costs of dramatising P. G. Wodehouse's A Damsel in Distress. The World of Pooh won the Lewis Carroll Shelf Award in 1958. 1929 onwards The success of his children's books was to become a source of considerable annoyance to Milne, whose self-avowed aim was to write whatever he pleased and who had, until then, found a ready audience for each change of direction: he had freed pre-war Punch from its ponderous facetiousness; he had made a considerable reputation as a playwright (like his idol J. M. Barrie) on both sides of the Atlantic; he had produced a witty piece of detective writing in The Red House Mystery (although this was severely criticised by Raymond Chandler for the implausibility of its plot in his essay The Simple Art of Murder in the eponymous collection that appeared in 1950). But once Milne had, in his own words, "said goodbye to all that in 70,000 words" (the approximate length of his four principal children's books), he had no intention of producing any reworkings lacking in originality, given that one of the sources of inspiration, his son, was growing older. Another reason Milne stopped writing children's books, and especially about Winnie-the-Pooh, was that he felt "amazement and disgust" over the fame his son was exposed to, and said that "I feel that the legal Christopher Robin has already had more publicity than I want for him. I do not want CR Milne to ever wish that his name were Charles Robert." In his literary home, Punch, where the When We Were Very Young verses had first appeared, Methuen continued to publish whatever Milne wrote, including the long poem "The Norman Church" and an assembly of articles entitled Year In, Year Out (which Milne likened to a benefit night for the author). In 1930, Milne adapted Kenneth Grahame's novel The Wind in the Willows for the stage as Toad of Toad Hall. The title was an implicit admission that such chapters as Chapter 7, "The Piper at the Gates of Dawn," could not survive translation to the theatre. A special introduction written by Milne is included in some editions of Grahame's novel. Milne and his wife became estranged from their son, who came to resent what he saw as his father's exploitation of his childhood and came to hate the books that had thrust him into the public eye. Christopher's marriage to his first cousin, Lesley de Sélincourt, distanced him still further from his parents – Lesley's father and Christopher's mother had not spoken to each other for 30 years. Death and legacy Commemoration A. A. Milne died at his home in Hartfield, Sussex, on 31 January 1956, nearly two weeks after his 74th birthday. After a memorial service in London, his ashes were scattered in a crematorium's memorial garden in Brighton. The rights to A. A. Milne's Pooh books were left to four beneficiaries: his family, the Royal Literary Fund, Westminster School and the Garrick Club. After Milne's death in 1956, thirteen days after his 74th birthday, his widow sold her rights to the Pooh characters to Stephen Slesinger, whose widow sold the rights after Slesinger's death to the Walt Disney Company, which has made many Pooh cartoon movies, a Disney Channel television show, as well as Pooh-related merchandise. In 2001, the other beneficiaries sold their interest in the estate to the Disney Corporation for $350m. Previously Disney had been paying twice-yearly royalties to these beneficiaries. The estate of E. H. Shepard also received a sum in the deal. The UK copyright on the text of the original Winnie the Pooh books expires on 1 January 2027; at the beginning of the year after the 70th anniversary of the author's death (PMA-70), and has already expired in those countries with a PMA-50 rule. This applies to all of Milne's works except those first published posthumously. The illustrations in the Pooh books will remain under copyright until the same amount of time has passed, after the illustrator's death; in the UK, this will be on 1 January 2047. In the US, copyright will not expire until 95 years after publication for each of Milne's books first published before 1978, but this includes the illustrations. In 2008, a collection of original illustrations featuring Winnie-the-Pooh and his animal friends sold for more than £1.2 million at auction in Sotheby's, London. Forbes magazine ranked Winnie the Pooh the most valuable fictional character in 2002; Winnie the Pooh merchandising products alone had annual sales of more than $5.9 billion. In 2005, Winnie the Pooh generated $6 billion, a figure surpassed only by Mickey Mouse. A memorial plaque in Ashdown Forest, unveiled by Christopher Robin in 1979, commemorates the work of A. A. Milne and Shepard in creating the world of Pooh. The inscription states they "captured the magic of Ashdown Forest, and gave it to the world". Milne once wrote of Ashdown Forest: "In that enchanted place on the top of the forest a little boy and his bear will always be playing." In 2003, Winnie-the-Pooh was ranked number 7 on the BBC's The Big Read poll which determined the UK's "best-loved novels". In 2006, Winnie-the-Pooh received a star on the Hollywood Walk of Fame, marking the 80th birthday of Milne's creation. Marking the 90th anniversary of Milne's creation of the character, and the 90th birthday of Queen Elizabeth II, Winnie-the-Pooh Meets the Queen (2016) sees Pooh meet the Queen at Buckingham Palace. The illustrated and audio adventure is narrated by the actor Jim Broadbent. Also in 2016, a new character, a Penguin, was unveiled in The Best Bear in All the World, which was inspired by a long-lost photograph of Milne and his son Christopher with a toy penguin. An exhibition entitled Winnie-the-Pooh: Exploring a Classic appeared at the Victoria and Albert Museum in London from 9 December 2017 to 8 April 2018. Several of Milne's children's poems were set to music by the composer Harold Fraser-Simson. His poems have been parodied many times, including with the books When We Were Rather Older and Now We Are Sixty. The 1963 film The King's Breakfast was based on Milne's poem of the same name. Milne has been portrayed in television and film. Domhnall Gleeson plays him in Goodbye Christopher Robin, a 2017 biographical drama film. In the 2018 fantasy film Christopher Robin, an extension of the Disney Winnie the Pooh franchise, Tristan Sturrock plays Milne, and filming took place at Ashdown Forest. An elementary school in Houston, Texas, operated by the Houston Independent School District (HISD), is named after Milne. The school, A. A. Milne Elementary School in Brays Oaks, opened in 1991. Archive The bulk of A. A. Milne's papers are housed at the Harry Ransom Center at the University of Texas at Austin. The collection, established at the center in 1964, consists of manuscript drafts and fragments for over 150 of Milne's works, as well as correspondence, legal documents, genealogical records, and some personal effects. The library division holds several books formerly belonging to Milne and his wife Dorothy. The Harry Ransom Center also has small collections of correspondence from Christopher Robin Milne and Milne's frequent illustrator Ernest Shepard. The original manuscripts for Winnie the Pooh and The House at Pooh Corner are archived separately at Trinity College Library, Cambridge. Religious views Milne did not speak out much on the subject of religion, although he used religious terms to explain his decision, while remaining a pacifist, to join the British Home Guard: "In fighting Hitler," he wrote, "we are truly fighting the Devil, the Anti-Christ ... Hitler was a crusader against God." His best known comment on the subject was recalled on his death: He wrote in the poem "Explained": He also wrote in the poem "Vespers": Works Novels Lovers in London (1905.

https://en.wikipedia.org/wiki/Asociaci%C3%B3n%20Alumni

Asociación Alumni

Asociación Alumni, usually just Alumni, is an Argentine rugby union club located in Tortuguitas, Greater Buenos Aires. The senior squad currently competes at Top 12, the first division of the Unión de Rugby de Buenos Aires league system. The club has ties with former football club Alumni because both were established by Buenos Aires English High School students. History Background The first club with the name "Alumni" played association football, having been found in 1898 by students of Buenos Aires English High School (BAEHS) along with director Alexander Watson Hutton. Originally under the name "English High School A.C.", the team would be later obliged by the Association to change its name, therefore "Alumni" was chosen, following a proposal by Carlos Bowers, a former student of the school. Alumni was the most successful team during the first years of Argentine football, winning 10 of 14 league championships contested. Alumni is still considered the first great football team in the country. Alumni was reorganised in 1908, "in order to encourage people to practise all kind of sports, specially football". This was the last try to develop itself as a sports club rather than just a football team, such as Lomas, Belgrano and Quilmes had successfully done in the past, but the efforts were not enough. Alumni played its last game in 1911 and was definitely dissolved on April 24, 1913. Rebirth through rugby In 1951, two guards of the BAEHS, Daniel Ginhson (also a former player of Buenos Aires F.C.) and Guillermo Cubelli, supported by the school's alumni and fathers of the students, they decided to establish a club focused on rugby union exclusively. Former players still alive of Alumni football club and descendants of other players already dead gave their permission to use the name "Alumni". On December 13, in a meeting presided by Carlos Bowers himself (who had proposed the name "Alumni" to the original football team 50 years before), the club was officially established under the name "Asociación Juvenil Alumni", also adopting the same colors as its predecessor. The team achieved good results and in 1960 the club presented a team that won the third division of the Buenos Aires league, reaching the second division. Since then, Alumni has played at the highest level of Argentine rugby and its rivalry with Belgrano Athletic Club is one of the fiercest local derbies in Buenos Aires. Alumni would later climb up to first division winning 5 titles: 4 consecutive between 1989 and 1992, and the other in 2001. In 2002, Alumni won its first Nacional de Clubes title, defeating Jockey Club de Rosario 23–21 in the final.

https://en.wikipedia.org/wiki/Albert%20Speer

Albert Speer

Berthold Konrad Hermann Albert Speer (; ; 19 March 1905 – 1 September 1981) was a German architect who served as the Minister of Armaments and War Production in Nazi Germany during most of World War II. A close ally of Adolf Hitler, he was convicted at the Nuremberg trials and sentenced to 20 years in prison. An architect by training, Speer joined the Nazi Party in 1931. His architectural skills made him increasingly prominent within the Party, and he became a member of Hitler's inner circle. Hitler commissioned him to design and construct structures including the Reich Chancellery and the Nazi party rally grounds in Nuremberg. In 1937, Hitler appointed Speer as General Building Inspector for Berlin. In this capacity he was responsible for the Central Department for Resettlement that evicted Jewish tenants from their homes in Berlin. In February 1942, Speer was appointed as Reich Minister of Armaments and War Production. Using misleading statistics, he promoted himself as having performed an armaments miracle that was widely credited with keeping Germany in the war. In 1944, Speer established a task force to increase production of fighter aircraft. It became instrumental in exploiting slave labor for the benefit of the German war effort. After the war, Speer was among the 24 "major war criminals" arrested and charged with the crimes of the Nazi regime at the Nuremberg trials. He was found guilty of war crimes and crimes against humanity, principally for the use of slave labor, narrowly avoiding a death sentence. Having served his full term, Speer was released in 1966. He used his writings from the time of imprisonment as the basis for two autobiographical books, Inside the Third Reich and Spandau: The Secret Diaries. Speer's books were a success; the public was fascinated by an inside view of the Third Reich. Speer died of a stroke in 1981. Little remains of his personal architectural work. Through his autobiographies and interviews, Speer carefully constructed an image of himself as a man who deeply regretted having failed to discover the monstrous crimes of the Third Reich. He continued to deny explicit knowledge of, and responsibility for the Holocaust. This image dominated his historiography in the decades following the war, giving rise to the "Speer Myth": the perception of him as an apolitical technocrat responsible for revolutionizing the German war machine. The myth began to fall apart in the 1980s, when the armaments miracle was attributed to Nazi propaganda. Adam Tooze wrote in The Wages of Destruction that the idea that Speer was an apolitical technocrat was "absurd". Martin Kitchen, writing in Speer: Hitler's Architect, stated that much of the increase in Germany's arms production was actually due to systems instituted by Speer's predecessor (Fritz Todt) and furthermore that Speer was intimately involved in the "Final Solution". Early years and personal life Speer was born in Mannheim, into an upper-middle-class family. He was the second of three sons of Luise Máthilde Wilhelmine (Hommel) and Albert Friedrich Speer. In 1918, the family leased their Mannheim residence and moved to a home they had in Heidelberg. Henry T. King, deputy prosecutor at the Nuremberg trials who later wrote a book about Speer said, "Love and warmth were lacking in the household of Speer's youth." His brothers, Ernst and Hermann, bullied him throughout his childhood. Speer was active in sports, taking up skiing and mountaineering. He followed in the footsteps of his father and grandfather and studied architecture. Speer began his architectural studies at the University of Karlsruhe instead of a more highly acclaimed institution because the hyperinflation crisis of 1923 limited his parents' income. In 1924, when the crisis had abated, he transferred to the "much more reputable" Technical University of Munich. In 1925, he transferred again, this time to the Technical University of Berlin where he studied under Heinrich Tessenow, whom Speer greatly admired. After passing his exams in 1927, Speer became Tessenow's assistant, a high honor for a man of 22. As such, Speer taught some of his classes while continuing his own postgraduate studies. In Munich Speer began a close friendship, ultimately spanning over 50 years, with Rudolf Wolters, who also studied under Tessenow. In mid-1922, Speer began courting Margarete (Margret) Weber (1905–1987), the daughter of a successful craftsman who employed 50 workers. The relationship was frowned upon by Speer's class-conscious mother, who felt the Webers were socially inferior. Despite this opposition, the two married in Berlin on 28 August 1928; seven years elapsed before Margarete was invited to stay at her in-laws' home. The couple would have six children together, but Albert Speer grew increasingly distant from his family after 1933. He remained so even after his release from imprisonment in 1966, despite their efforts to forge closer bonds. Party architect and government functionary Joining the Nazis (1931–1934) In January 1931, Speer applied for Nazi Party membership, and on 1 March 1931, he became member number 474,481. The same year, with stipends shrinking amid the Depression, Speer surrendered his position as Tessenow's assistant and moved to Mannheim, hoping to make a living as an architect. After he failed to do so, his father gave him a part-time job as manager of his properties. In July 1932, the Speers visited Berlin to help out the Party before the Reichstag elections. While they were there his friend, Nazi Party official Karl Hanke recommended the young architect to Joseph Goebbels to help renovate the Party's Berlin headquarters. When the commission was completed, Speer returned to Mannheim and remained there as Hitler took office in January 1933. The organizers of the 1933 Nuremberg Rally asked Speer to submit designs for the rally, bringing him into contact with Hitler for the first time. Neither the organizers nor Rudolf Hess were willing to decide whether to approve the plans, and Hess sent Speer to Hitler's Munich apartment to seek his approval. This work won Speer his first national post, as Nazi Party "Commissioner for the Artistic and Technical Presentation of Party Rallies and Demonstrations". Shortly after Hitler came into power, he began to make plans to rebuild the chancellery. At the end of 1933, he contracted Paul Troost to renovate the entire building. Hitler appointed Speer, whose work for Goebbels had impressed him, to manage the building site for Troost. As Chancellor, Hitler had a residence in the building and came by every day to be briefed by Speer and the building supervisor on the progress of the renovations. After one of these briefings, Hitler invited Speer to lunch, to the architect's great excitement. Speer quickly became part of Hitler's inner circle; he was expected to call on him in the morning for a walk or chat, to provide consultation on architectural matters, and to discuss Hitler's ideas. Most days he was invited to dinner. In the English version of his memoirs, Speer says that his political commitment merely consisted of paying his "monthly dues". He assumed his German readers would not be so gullible and told them the Nazi Party offered a "new mission". He was more forthright in an interview with William Hamsher in which he said he joined the party in order to save "Germany from Communism". After the war, he claimed to have had little interest in politics at all and had joined almost by chance. Like many of those in power in the Third Reich, he was not an ideologue, "nor was he anything more than an instinctive anti-Semite." The historian Magnus Brechtken, discussing Speer, said he did not give anti-Jewish public speeches and that his anti-Semitism can best be understood through his actions—which were anti-Semitic. Brechtken added that, throughout Speer's life, his central motives were to gain power, rule, and acquire wealth. Nazi architect (1934–1937) When Troost died on 21 January 1934, Speer effectively replaced him as the Party's chief architect. Hitler appointed Speer as head of the Chief Office for Construction, which placed him nominally on Hess's staff. One of Speer's first commissions after Troost's death was the Zeppelinfeld stadium in Nuremberg. It was used for Nazi propaganda rallies and can be seen in Leni Riefenstahl's propaganda film Triumph of the Will. The building was able to hold 340,000 people. Speer insisted that as many events as possible be held at night, both to give greater prominence to his lighting effects and to hide the overweight Nazis. Nuremberg was the site of many official Nazi buildings. Many more buildings were planned. If built, the German Stadium would have accommodated 400,000 spectators. Speer modified Werner March's design for the Olympic Stadium being built for the 1936 Summer Olympics. He added a stone exterior that pleased Hitler. Speer designed the German Pavilion for the 1937 international exposition in Paris. Berlin's General Building Inspector (1937–1942) On 30 January 1937, Hitler appointed Speer as General Building Inspector for the Reich Capital. This carried with it the rank of State Secretary in the Reich government and gave him extraordinary powers over the Berlin city government. He was to report directly to Hitler, and was independent of both the mayor and the Gauleiter of Berlin. Hitler ordered Speer to develop plans to rebuild Berlin. These centered on a three-mile-long grand boulevard running from north to south, which Speer called the Prachtstrasse, or Street of Magnificence; he also referred to it as the "North–South Axis". At the northern end of the boulevard, Speer planned to build the Volkshalle, a huge domed assembly hall over high, with floor space for 180,000 people. At the southern end of the avenue, a great triumphal arch, almost high and able to fit the Arc de Triomphe inside its opening, was planned. The existing Berlin railroad termini were to be dismantled, and two large new stations built. Speer hired Wolters as part of his design team, with special responsibility for the Prachtstrasse. The outbreak of World War II in 1939 led to the postponement, and later the abandonment, of these plans. Plans to build a new Reich chancellery had been underway since 1934. Land had been purchased by the end of 1934 and starting in March 1936 the first buildings were demolished to create space at Voßstraße. Speer was involved virtually from the beginning. In the aftermath of the Night of the Long Knives, he had been commissioned to renovate the Borsig Palace on the corner of Voßstraße and Wilhelmstraße as headquarters of the Sturmabteilung (SA). He completed the preliminary work for the new chancellery by May 1936. In June 1936 he charged a personal honorarium of 30,000 Reichsmark and estimated the chancellery would be completed within three to four years. Detailed plans were completed in July 1937 and the first shell of the new chancellery was complete on 1 January 1938. On 27 January 1938, Speer received plenipotentiary powers from Hitler to finish the new chancellery by 1 January 1939. For propaganda Hitler claimed during the topping-out ceremony on 2 August 1938, that he had ordered Speer to complete the new chancellery that year. Shortages of labor meant the construction workers had to work in ten-to-twelve-hour shifts. The Schutzstaffel (SS) built two concentration camps in 1938 and used the inmates to quarry stone for its construction. A brick factory was built near the Oranienburg concentration camp at Speer's behest; when someone commented on the poor conditions there, Speer stated, "The Yids got used to making bricks while in Egyptian captivity". The chancellery was completed in early January 1939. The building itself was hailed by Hitler as the "crowning glory of the greater German political empire". During the Chancellery project, the pogrom of Kristallnacht took place. Speer made no mention of it in the first draft of Inside the Third Reich. It was only on the urgent advice of his publisher that he added a mention of seeing the ruins of the Central Synagogue in Berlin from his car. Kristallnacht accelerated Speer's ongoing efforts to dispossess Berlin's Jews from their homes. From 1939 on, Speer's Department used the Nuremberg Laws to evict Jewish tenants of non-Jewish landlords in Berlin, to make way for non-Jewish tenants displaced by redevelopment or bombing. Eventually, 75,000 Jews were displaced by these measures. Speer denied he knew they were being put on Holocaust trains and claimed that those displaced were, "Completely free and their families were still in their apartments". He also said: " ... en route to my ministry on the city highway, I could see ... crowds of people on the platform of nearby Nikolassee Railroad Station. I knew that these must be Berlin Jews who were being evacuated. I am sure that an oppressive feeling struck me as I drove past. I presumably had a sense of somber events." Matthias Schmidt said Speer had personally inspected concentration camps and described his comments as an "outright farce". Martin Kitchen described Speer's often repeated line that he knew nothing of the "dreadful things" as hollow—because not only was he fully aware of the fate of the Jews he was actively participating in their persecution. As Germany started World War II in Europe, Speer instituted quick-reaction squads to construct roads or clear away debris; before long, these units would be used to clear bomb sites. Speer used forced Jewish labor on these projects, in addition to regular German workers. Construction stopped on the Berlin and Nüremberg plans at the outbreak of war. Though stockpiling of materials and other work continued, this slowed to a halt as more resources were needed for the armament industry. Speer's offices undertook building work for each branch of the military, and for the SS, using slave labor. Speer's building work made him among the wealthiest of the Nazi elite. Minister of Armaments Appointment and increasing power In 1941, Speer was elected to the Reichstag from electoral constituency 2 (Berlin-West). On 8 February 1942, Reich Minister of Armaments and Munitions Fritz Todt died in a plane crash shortly after taking off from Hitler's eastern headquarters at Rastenburg. Speer arrived there the previous evening and accepted Todt's offer to fly with him to Berlin. Speer cancelled some hours before take-off because the previous night he had been up late in a meeting with Hitler. Hitler appointed Speer in Todt's place. Martin Kitchen, a British historian, says that the choice was not surprising. Speer was loyal to Hitler, and his experience building prisoner of war camps and other structures for the military qualified him for the job. Speer succeeded Todt not only as Reich Minister but in all his other powerful positions, including Inspector General of German Roadways, Inspector General for Water and Energy and Head of the Nazi Party's Office of Technology. At the same time, Hitler also appointed Speer as head of the Organisation Todt, a massive, government-controlled construction company. Characteristically Hitler did not give Speer any clear remit; he was left to fight his contemporaries in the regime for power and control. As an example, he wanted to be given power over all armaments issues under Hermann Göring's Four Year Plan. Göring was reluctant to grant this. However Speer secured Hitler's support, and on 1 March 1942, Göring signed a decree naming Speer "General Plenipotentiary for Armament Tasks" in the Four Year Plan. Speer proved to be ambitious, unrelenting and ruthless. Speer set out to gain control not just of armaments production in the army, but in the whole armed forces. It did not immediately dawn on his political rivals that his calls for rationalization and reorganization were hiding his desire to sideline them and take control. By April 1942, Speer had persuaded Göring to create a three-member Central Planning Board within the Four Year Plan, which he used to obtain supreme authority over procurement and allocation of raw materials and scheduling of production in order to consolidate German war production in a single agency. Speer was fêted at the time, and in the post-war era, for performing an "armaments miracle" in which German war production dramatically increased. This miracle was brought to a halt in the summer of 1943 by, among other factors, the first sustained Allied bombing. Other factors probably contributed to the increase more than Speer himself. Germany's armaments production had already begun to result in increases under his predecessor, Todt. Naval armaments were not under Speer's supervision until October 1943, nor the Luftwaffe's armaments until June of the following year. Yet each showed comparable increases in production despite not being under Speer's control. Another factor that produced the boom in ammunition was the policy of allocating more coal to the steel industry. Production of every type of weapon peaked in June and July 1944, but there was now a severe shortage of fuel. After August 1944, oil from the Romanian fields was no longer available. Oil production became so low that any possibility of offensive action became impossible and weaponry lay idle. As Minister of Armaments, Speer was responsible for supplying weapons to the army. With Hitler's full agreement, he decided to prioritize tank production, and he was given unrivaled power to ensure success. Hitler was closely involved with the design of the tanks, but kept changing his mind about the specifications. This delayed the program, and Speer was unable to remedy the situation. In consequence, despite tank production having the highest priority, relatively little of the armaments budget was spent on it. This led to a significant German Army failure at the Battle of Prokhorovka, a major turning point on the Eastern Front against the Soviet Red Army. As head of Organisation Todt, Speer was directly involved in the construction and alteration of concentration camps. He agreed to expand Auschwitz and some other camps, allocating 13.7 million Reichsmarks for the work to be carried out. This allowed an extra 300 huts to be built at Auschwitz, increasing the total human capacity to 132,000. Included in the building works was material to build gas chambers, crematoria and morgues. The SS called this "Professor Speer's Special Programme". Speer realized that with six million workers drafted into the armed forces, there was a labor shortage in the war economy, and not enough workers for his factories. In response, Hitler appointed Fritz Sauckel as a "manpower dictator" to obtain new workers. Speer and Sauckel cooperated closely to meet Speer's labor demands. Hitler gave Sauckel a free hand to obtain labor, something that delighted Speer, who had requested 1,000,000 "voluntary" laborers to meet the need for armament workers. Sauckel had whole villages in France, Holland and Belgium forcibly rounded up and shipped to Speer's factories. Sauckel obtained new workers often using the most brutal methods. In occupied areas of the Soviet Union, that had been subject to partisan action, civilian men and women were rounded up en masse and sent to work forcibly in Germany. By April 1943, Sauckel had supplied 1,568,801 "voluntary" laborers, forced laborers, prisoners of war and concentration camp prisoners to Speer for use in his armaments factories. It was for the maltreatment of these people, that Speer was principally convicted at the Nuremberg Trials. Consolidation of arms production Following his appointment as Minister of Armaments, Speer was in control of armaments production solely for the Army. He coveted control of the production of armaments for the Luftwaffe and Kriegsmarine as well. He set about extending his power and influence with unexpected ambition. His close relationship with Hitler provided him with political protection, and he was able to outwit and outmaneuver his rivals in the regime. Hitler's cabinet was dismayed at his tactics, but, regardless, he was able to accumulate new responsibilities and more power. By July 1943, he had gained control of armaments production for the Luftwaffe and Kriegsmarine. In August 1943, he took control of most of the Ministry of Economics, to become, in Admiral Dönitz's words, "Europe's economic dictator". His formal title was changed on 2 September 1943, to "Reich Minister for Armaments and War Production". He had become one of the most powerful people in Nazi Germany. Speer and his hand-picked director of submarine construction Otto Merker believed that the shipbuilding industry was being held back by outdated methods, and revolutionary new approaches imposed by outsiders would dramatically improve output. This belief proved incorrect, and Speer and Merker's attempt to build the Kriegsmarines new generation of submarines, the Type XXI and Type XXIII, as prefabricated sections at different facilities rather than at single dockyards contributed to the failure of this strategically important program. The designs were rushed into production, and the completed submarines were crippled by flaws which resulted from the way they had been constructed. While dozens of submarines were built, few ever entered service. In December 1943, Speer visited Organisation Todt workers in Lapland, while there he seriously damaged his knee and was incapacitated for several months. He was under the dubious care of Professor Karl Gebhardt at a medical clinic called Hohenlychen where patients "mysteriously failed to survive". In mid-January 1944, Speer had a lung embolism and fell seriously ill. Concerned about retaining power, he did not appoint a deputy and continued to direct work of the Armaments Ministry from his bedside. Speer's illness coincided with the Allied "Big Week", a series of bombing raids on the German aircraft factories that were a devastating blow to aircraft production. His political rivals used the opportunity to undermine his authority and damage his reputation with Hitler. He lost Hitler's unconditional support and began to lose power. In response to the Allied Big Week, Adolf Hitler authorized the creation of a Fighter Staff committee. Its aim was to ensure the preservation and growth of fighter aircraft production. The task force was established by 1 March 1944, orders of Speer, with support from Erhard Milch of the Reich Aviation Ministry. Production of German fighter aircraft more than doubled between 1943 and 1944. The growth, however, consisted in large part of models that were becoming obsolescent and proved easy prey for Allied aircraft. On 1 August 1944, Speer merged the Fighter Staff into a newly formed Armament Staff committee. The Fighter Staff committee was instrumental in bringing about the increased exploitation of slave labor in the war economy. The SS provided 64,000 prisoners for 20 separate projects from various concentration camps including Mittelbau-Dora. Prisoners worked for Junkers, Messerschmitt, Henschel and BMW, among others. To increase production, Speer introduced a system of punishments for his workforce. Those who feigned illness, slacked off, sabotaged production or tried to escape were denied food or sent to concentration camps. In 1944, this became endemic; over half a million workers were arrested. By this time, 140,000 people were working in Speer's underground factories. These factories were death-traps; discipline was brutal, with regular executions. There were so many corpses at the Dora underground factory, for example, that the crematorium was overwhelmed. Speer's own staff described the conditions there as "hell". The largest technological advance under Speer's command came through the rocket program. It began in 1932 but had not supplied any weaponry. Speer enthusiastically supported the program and in March 1942 made an order for A4 rockets, the predecessor of the world's first ballistic missile, the V-2 rocket. The rockets were researched at a facility in Peenemünde along with the V-1 flying bomb. The V-2's first target was Paris on 8 September 1944. The program while advanced proved to be an impediment to the war economy. The large capital investment was not repaid in military effectiveness. The rockets were built at an underground factory at Mittelwerk. Labor to build the A4 rockets came from the Mittelbau-Dora concentration camp. Of the 60,000 people who ended up at the camp 20,000 died, due to the appalling conditions. On 14 April 1944, Speer lost control of Organisation Todt to his Deputy, Franz Xaver Dorsch. He opposed the assassination attempt against Hitler on 20 July 1944. He was not involved in the plot, and played a minor role in the regime's efforts to regain control over Berlin after Hitler survived. After the plot Speer's rivals attacked some of his closest allies and his management system fell out of favor with radicals in the party. He lost yet more authority. Defeat of Nazi Germany Losses of territory and a dramatic expansion of the Allied strategic bombing campaign caused the collapse of the German economy from late 1944. Air attacks on the transport network were particularly effective, as they cut the main centres of production off from essential coal supplies. In January 1945, Speer told Goebbels that armaments production could be sustained for at least a year. However, he concluded that the war was lost after Soviet forces captured the important Silesian industrial region later that month. Nevertheless, Speer believed that Germany should continue the war for as long as possible with the goal of winning better conditions from the Allies than the unconditional surrender they insisted upon. During January and February, Speer claimed that his ministry would deliver "decisive weapons" and a large increase in armaments production which would "bring about a dramatic change on the battlefield". Speer gained control over the railways in February, and asked Heinrich Himmler to supply concentration camp prisoners to work on their repair. By mid-March, Speer had accepted that Germany's economy would collapse within the next eight weeks. While he sought to frustrate directives to destroy industrial facilities in areas at risk of capture, so that they could be used after the war, he still supported the war's continuation. Speer provided Hitler with a memorandum on 15 March, which detailed Germany's dire economic situation and sought approval to cease demolitions of infrastructure. Three days later, he also proposed to Hitler that Germany's remaining military resources be concentrated along the Rhine and Vistula rivers in an attempt to prolong the fighting. This ignored military realities, as the German armed forces were unable to match the Allies' firepower and were facing total defeat. Hitler rejected Speer's proposal to cease demolitions. Instead, he issued the "Nero Decree" on 19 March, which called for the destruction of all infrastructure as the army retreated. Speer was appalled by this order, and persuaded several key military and political leaders to ignore it. During a meeting with Speer on 28/29 March, Hitler rescinded the decree and gave him authority over demolitions. Speer ended them, though the army continued to blow up bridges. By April, little was left of the armaments industry, and Speer had few official duties. Speer visited the Führerbunker on 22 April for the last time. He met Hitler and toured the damaged Chancellery before leaving Berlin to return to Hamburg. On 29 April, the day before committing suicide, Hitler dictated a final political testament which dropped Speer from the successor government. Speer was to be replaced by his subordinate, Karl-Otto Saur. Speer was disappointed that Hitler had not selected him as his successor. After Hitler's death, Speer offered his services to the so-called Flensburg Government, headed by Hitler's successor, Karl Dönitz. He took a role in that short-lived regime as Minister of Industry and Production. Speer provided information to the Allies, regarding the effects of the air war, and on a broad range of subjects, beginning on 10 May. On 23 May, two weeks after the surrender of German forces, British troops arrested the members of the Flensburg Government and brought Nazi Germany to a formal end. Post-war Nuremberg trial Speer was taken to several internment centres for Nazi officials and interrogated. In September 1945, he was told that he would be tried for war crimes, and several days later, he was moved to Nuremberg and incarcerated there. Speer was indicted on four counts: participating in a common plan or conspiracy for the accomplishment of crime against peace; planning, initiating and waging wars of aggression and other crimes against peace; war crimes; and crimes against humanity. The chief United States prosecutor, Robert H. Jackson, of the U.S. Supreme Court said, "Speer joined in planning and executing the program to dragoon prisoners of war and foreign workers into German war industries, which waxed in output while the workers waned in starvation." Speer's attorney, Hans Flächsner, successfully contrasted Speer from other defendants and portrayed him as an artist thrust into political life who had always remained a non-ideologue. Speer was found guilty of war crimes and crimes against humanity, principally for the use of slave labor and forced labor. He was acquitted on the other two counts. He had claimed that he was unaware of Nazi extermination plans, and the Allies had no proof that he was aware. His claim was revealed to be false in a private correspondence written in 1971 and publicly disclosed in 2007. On 1 October 1946, he was sentenced to 20 years' imprisonment. While three of the eight judges (two Soviet and American Francis Biddle) advocated the death penalty for Speer, the other judges did not, and a compromise sentence was reached after two days of discussions. Imprisonment On 18 July 1947, Speer was transferred to Spandau Prison in Berlin to serve his prison term. There he was known as Prisoner Number Five. Speer's parents died while he was incarcerated. His father, who died in 1947, despised the Nazis and was silent upon meeting Hitler. His mother died in 1952. As a Nazi Party member, she had greatly enjoyed dining with Hitler. Wolters and longtime Speer secretary Annemarie Kempf, while not permitted direct communication with Speer in Spandau, did what they could to help his family and carry out the requests Speer put in letters to his wife—the only written communication he was officially allowed. Beginning in 1948, Speer had the services of Toni Proost, a sympathetic Dutch orderly to smuggle mail and his writings. In 1949, Wolters opened a bank account for Speer and began fundraising among those architects and industrialists who had benefited from Speer's activities during the war. Initially, the funds were used only to support Speer's family, but increasingly the money was used for other purposes. They paid for Toni Proost to go on holiday, and for bribes to those who might be able to secure Speer's release. Once Speer became aware of the existence of the fund, he sent detailed instructions about what to do with the money. Wolters raised a total of DM158,000 for Speer over the final seventeen years of his sentence. The prisoners were forbidden to write memoirs. Speer was able to have his writings sent to Wolters, however, and they eventually amounted to 20,000 pages. He had completed his memoirs by November 1953, which became the basis of Inside the Third Reich. In Spandau Diaries, Speer aimed to present himself as a tragic hero who had made a Faustian bargain for which he endured a harsh prison sentence. Much of Speer's energy was dedicated to keeping fit, both physically and mentally, during his long confinement. Spandau had a large enclosed yard where inmates were allocated plots of land for gardening. Speer created an elaborate garden complete with lawns, flower beds, shrubbery, and fruit trees. To make his daily walks around the garden more engaging Speer embarked on an imaginary trip around the globe. Carefully measuring distance travelled each day, he mapped distances to the real-world geography. He had walked more than , ending his sentence near Guadalajara, Mexico. Speer also read, studied architectural journals, and brushed up on English and French. In his writings, Speer claimed to have finished five thousand books while in prison. His sentence of twenty years amounted to 7,305 days, which only allotted one and a half days per book. Speer's supporters maintained calls for his release. Among those who pledged support for his sentence to be commuted were Charles de Gaulle and US diplomat George Wildman Ball. Willy Brandt was an advocate of his release, putting an end to the de-Nazification proceedings against him, which could have caused his property to be confiscated. Speer's efforts for an early release came to naught. The Soviet Union, having demanded a death sentence at trial, was unwilling to entertain a reduced sentence. Speer served a full term and was released at midnight on 1 October 1966. Release and later life Speer's release from prison was a worldwide media event. Reporters and photographers crowded both the street outside Spandau and the lobby of the Hotel Berlin where Speer spent the night. He said little, reserving most comments for a major interview published in Der Spiegel in November 1966. Although he stated he hoped to resume an architectural career, his sole project, a collaboration for a brewery, was unsuccessful. Instead, he revised his Spandau writings into two autobiographical books, Inside the Third Reich (in German, Erinnerungen, or Reminiscences) and Spandau: The Secret Diaries. He later published a work about Himmler and the SS which has been published in English as The Slave State: Heinrich Himmler's Masterplan for SS Supremacy or Infiltration: How Heinrich Himmler Schemed to Build an SS Industrial Empire (in German, Der Sklavenstaat - Meine Auseinandersetzung mit der SS). Speer was aided in shaping the works by Joachim Fest and Wolf Jobst Siedler from the publishing house Ullstein. He found himself unable to re-establish a relationship with his children, even with his son Albert who had also become an architect. According to Speer's daughter Hilde Schramm, "One by one my sister and brothers gave up. There was no communication." He supported Hermann, his brother, financially after the war. However, his other brother Ernst had died in the Battle of Stalingrad, despite repeated requests from his parents for Speer to repatriate him. Following his release from Spandau, Speer donated the Chronicle, his personal diary, to the German Federal Archives. It had been edited by Wolters and made no mention of the Jews. David Irving discovered discrepancies between the deceptively edited Chronicle and independent documents. Speer asked Wolters to destroy the material he had omitted from his donation but Wolters refused and retained an original copy. Wolters' friendship with Speer deteriorated and one year before Speer's death Wolters gave Matthias Schmidt access to the unedited Chronicle. Schmidt authored the first book that was highly critical of Speer. Speer's memoirs were a phenomenal success. The public was fascinated by an inside view of the Third Reich and a major war criminal became a popular figure almost overnight. Importantly, he provided an alibi to older Germans who had been Nazis. If Speer, who had been so close to Hitler, had not known the full extent of the crimes of the Nazi regime and had just been "following orders", then they could tell themselves and others they too had done the same. So great was the need to believe this "Speer Myth" that Fest and Siedler were able to strengthen it—even in the face of mounting historical evidence to the contrary. Death Speer made himself widely available to historians and other enquirers. In October 1973, he made his first trip to Britain, flying to London to be interviewed on the BBC Midweek programme. In the same year, he appeared on the television programme The World at War. Speer returned to London in 1981 to participate in the BBC Newsnight programme. He suffered a stroke and died in London on 1 September. He had remained married to his wife, but he had formed a relationship with a German woman living in London and was with her at the time of his death. His daughter, Margret Nissen, wrote in her 2005 memoirs that after his release from Spandau he spent all of his time constructing the "Speer Myth". The Speer myth The Good Nazi After his release from Spandau, Speer portrayed himself as the "good Nazi". He was well-educated, middle class, and bourgeois, and could contrast himself with those who, in the popular mind, typified "bad Nazis". In his memoirs and interviews, he had distorted the truth and made so many major omissions that his lies became known as "myths". Speer even invented his own birth's circumstances, stating falsely that he was born at midday amid crashes of thunder and bells of the nearby Christ Church, whereas it was between three and five o'clock, and the church was built only some years after. Speer took his myth-making to a mass media level and his "cunning apologies" were reproduced frequently in post-war Germany. Isabell Trommer writes in her biography of Speer that Fest and Siedler were co-authors of Speer's memoirs and co-creators of his myths. In return they were paid handsomely in royalties and other financial inducements. Speer, Siedler and Fest had constructed a masterpiece; the image of the "good Nazi" remained in place for decades, despite historical evidence indicating that it was false. Speer had carefully constructed an image of himself as an apolitical technocrat who deeply regretted having failed to discover the monstrous crimes of the Third Reich. This construction was accepted almost at face value by historian Hugh Trevor-Roper when investigating the death of Adolf Hitler for British Intelligence and in writing The Last Days of Hitler. Trevor-Roper frequently refers to Speer as "a technocrat [who] nourished a technocrat's philosophy", one who cared only for his building projects or his ministerial duties, and who thought that politics was irrelevant, at least until Hitler's Nero Decree which Speer, according to his own telling, worked assiduously to counter. Trevor-Roper – who calls Speer an administrative genius whose basic instincts were peaceful and constructive – does take Speer to task, however, for his failure to recognize the immorality of Hitler and Nazism, calling him "the real criminal of Nazi Germany": For ten years he sat at the very centre of political power; his keen intelligence diagnosed the nature and observed the mutations of Nazi government and policy; he saw and despised the personalities around him; he heard their outrageous orders and understood their fantastic ambitions; but he did nothing. Supposing politics to be irrelevant, he turned aside and built roads and bridges and factories, while the logical consequences of government by madmen emerged. Ultimately, when their emergence involved the ruin of all his work, Speer accepted the consequences and acted. Then it was too late; Germany had been destroyed. After Speer's death, Matthias Schmidt published a book that demonstrated that Speer had ordered the eviction of Jews from their Berlin homes. By 1999, historians had amply demonstrated that Speer had lied extensively. Even so, public perceptions of Speer did not change substantially until Heinrich Breloer aired a biographical film on TV in 2004. The film began a process of demystification and critical reappraisal. Adam Tooze in his book The Wages of Destruction said Speer had manoeuvred himself through the ranks of the regime skillfully and ruthlessly and that the idea he was a technocrat blindly carrying out orders was "absurd". Trommer said he was not an apolitical technocrat; instead, he was one of the most powerful and unscrupulous leaders in the Nazi regime. Kitchen said he had deceived the Nuremberg Tribunal and post-war Germany. Brechtken said that if his extensive involvement in the Holocaust had been known at the time of his trial he would have been sentenced to death. The image of the good Nazi was supported by numerous Speer myths. In addition to the myth that he was an apolitical technocrat, he claimed he did not have full knowledge of the Holocaust or the persecution of the Jews. Another myth posits that Speer revolutionized the German war machine after his appointment as Minister of Armaments. He was credited with a dramatic increase in the shipment of arms that was widely reported as keeping Germany in the war. Another myth centered around a faked plan to assassinate Hitler with poisonous gas. The idea for this myth came to him after he recalled the panic when car fumes came through an air ventilation system. He fabricated the additional details. Brechtken wrote that his most brazen lie was fabricated during an interview with a French journalist in 1952. The journalist described an invented scenario in which Speer had refused Hitler's orders and Hitler had left with tears in his eyes. Speer liked the scenario so much that he wrote it into his memoirs. The journalist had unwittingly collaborated in one of his myths. Speer also sought to portray himself as an opponent of Hitler's leadership. Despite his opposition to the 20 July plot, he falsely claimed in his memoirs to have been sympathetic to the plotters. He maintained Hitler was cool towards him for the remainder of his life after learning they had included him on a list of potential ministers. This formed a key element of the myths Speer encouraged. Speer also falsely claimed that he had realised the war was lost at an early stage, and thereafter worked to preserve the resources needed for the civilian population's survival. In reality, he had sought to prolong the war until further resistance was impossible, thus contributing to the large number of deaths and the extensive destruction Germany suffered in the conflict's final months. Denial of responsibility Speer maintained at the Nuremberg trials and in his memoirs that he had no direct knowledge of the Holocaust. He admitted only to being uncomfortable around Jews in the published version of the Spandau Diaries. In his final statement at Nuremberg, Speer gave the impression of apologizing, although he did not directly admit any personal guilt and the only victim he mentioned was the German people. Historian Martin Kitchen states that Speer was actually "fully aware of what had happened to the Jews" and was "intimately involved in the 'Final Solution'". Brechtken said Speer only admitted to a generalized responsibility for the Holocaust to hide his direct and actual responsibility. Speer was photographed with slave laborers at Mauthausen concentration camp during a visit on 31 March 1943; he also visited Gusen concentration camp. Although survivor Francisco Boix testified at the Nuremberg trials about Speer's visit, Taylor writes that, had the photo been available, he would have been hanged. In 2005, The Daily Telegraph reported that documents had surfaced indicating that Speer had approved the allocation of materials for the expansion of Auschwitz concentration camp after two of his assistants inspected the facility on a day when almost a thousand Jews were massacred. Heinrich Breloer, discussing the construction of Auschwitz, said Speer was not just a cog in the work—he was the "terror itself". Speer did not deny being present at the Posen speeches to Nazi leaders at a conference in Posen (Poznań) on 6 October 1943, but claimed to have left the auditorium before Himmler said during his speech: "The grave decision had to be taken to cause this people to vanish from the earth", and later, "The Jews must be exterminated". Speer is mentioned several times in the speech, and Himmler addresses him directly. In 2007, The Guardian reported that a letter from Speer dated 23 December 1971, had been found in a collection of his correspondence with Hélène Jeanty, the widow of a Belgian resistance fighter. In the letter, Speer says, "There is no doubt—I was present as Himmler announced on October 6, 1943, that all Jews would be killed." Armaments miracle Speer was credited with an "armaments miracle". During the winter of 1941–42, in the light of Germany's disastrous defeat in the Battle of Moscow, the German leadership including Friedrich Fromm, Georg Thomas and Fritz Todt had come to the conclusion that the war could not be won. The rational position to adopt was to seek a political solution that would end the war without defeat. Speer in response used his propaganda expertise to display a new dynamism of the war economy. He produced spectacular statistics, claiming a sixfold increase in munitions production, a fourfold increase in artillery production, and he sent further propaganda to the newsreels of the country. He was able to curtail the discussion that the war should be ended. The armaments "miracle" was a myth; Speer had used statistical manipulation to support his claims. The production of armaments did go up; however, this was due to the normal causes of reorganization before Speer came to office, the relentless mobilization of slave labor and a deliberate reduction in the quality of output to favor quantity. By July 1943 Speer's armaments propaganda became irrelevant because a catalogue of dramatic defeats on the battlefield meant the prospect of losing the war could no longer be hidden from the German public. Architectural legacy Little remains of Speer's personal architectural works, other than the plans and photographs. No buildings designed by Speer during the Nazi era are extant in Berlin, other than the 4 entrance pavilions and underpasses leading to the Victory Column or Siegessäule, and the Schwerbelastungskörper, a heavy load-bearing body built around 1941. The concrete cylinder, high, was used to measure ground subsidence as part of feasibility studies for a massive triumphal arch and other large structures planned within Hitler's post-war renewal project for the city of Berlin as the world capital Germania. The cylinder is now a protected landmark and is open to the public. The tribune of the Zeppelinfeld stadium in Nuremberg, though partly demolished, can also be seen. During the war, the Speer-designed Reich Chancellery was largely destroyed by air raids and in the Battle of Berlin. The exterior walls survived, but they were eventually dismantled by the Soviets. Unsubstantiated rumors have claimed that the remains were used for other building projects such as the Humboldt University, Mohrenstraße metro station and Soviet war memorials in Berlin.

Axon

An axon (from Greek ἄξων áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the periphery to the cell body and from the cell body to the spinal cord along another branch of the same axon. Axon dysfunction can be the cause of many inherited and acquired neurological disorders that affect both the peripheral and central neurons. Nerve fibers are classed into three typesgroup A nerve fibers, group B nerve fibers, and group C nerve fibers. Groups A and B are myelinated, and group C are unmyelinated. These groups include both sensory fibers and motor fibers. Another classification groups only the sensory fibers as Type I, Type II, Type III, and Type IV. An axon is one of two types of cytoplasmic protrusions from the cell body of a neuron; the other type is a dendrite. Axons are distinguished from dendrites by several features, including shape (dendrites often taper while axons usually maintain a constant radius), length (dendrites are restricted to a small region around the cell body while axons can be much longer), and function (dendrites receive signals whereas axons transmit them). Some types of neurons have no axon and transmit signals from their dendrites. In some species, axons can emanate from dendrites known as axon-carrying dendrites. No neuron ever has more than one axon; however in invertebrates such as insects or leeches the axon sometimes consists of several regions that function more or less independently of each other. Axons are covered by a membrane known as an axolemma; the cytoplasm of an axon is called axoplasm. Most axons branch, in some cases very profusely. The end branches of an axon are called telodendria. The swollen end of a telodendron is known as the axon terminal which joins the dendron or cell body of another neuron forming a synaptic connection. Axons make contact with other cellsusually other neurons but sometimes muscle or gland cellsat junctions called synapses. In some circumstances, the axon of one neuron may form a synapse with the dendrites of the same neuron, resulting in an autapse. At a synapse, the membrane of the axon closely adjoins the membrane of the target cell, and special molecular structures serve to transmit electrical or electrochemical signals across the gap. Some synaptic junctions appear along the length of an axon as it extends; these are called en passant ("in passing") synapses and can be in the hundreds or even the thousands along one axon. Other synapses appear as terminals at the ends of axonal branches. A single axon, with all its branches taken together, can innervate multiple parts of the brain and generate thousands of synaptic terminals. A bundle of axons make a nerve tract in the central nervous system, and a fascicle in the peripheral nervous system. In placental mammals the largest white matter tract in the brain is the corpus callosum, formed of some 200 million axons in the human brain. Anatomy Axons are the primary transmission lines of the nervous system, and as bundles they form nerves. Some axons can extend up to one meter or more while others extend as little as one millimeter. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across). The largest mammalian axons can reach a diameter of up to 20 µm. The squid giant axon, which is specialized to conduct signals very rapidly, is close to 1 millimeter in diameter, the size of a small pencil lead. The numbers of axonal telodendria (the branching structures at the end of the axon) can also differ from one nerve fiber to the next. Axons in the central nervous system (CNS) typically show multiple telodendria, with many synaptic end points. In comparison, the cerebellar granule cell axon is characterized by a single T-shaped branch node from which two parallel fibers extend. Elaborate branching allows for the simultaneous transmission of messages to a large number of target neurons within a single region of the brain. There are two types of axons in the nervous system: myelinated and unmyelinated axons. Myelin is a layer of a fatty insulating substance, which is formed by two types of glial cells: Schwann cells and oligodendrocytes. In the peripheral nervous system Schwann cells form the myelin sheath of a myelinated axon. Oligodendrocytes form the insulating myelin in the CNS. Along myelinated nerve fibers, gaps in the myelin sheath known as nodes of Ranvier occur at evenly spaced intervals. The myelination enables an especially rapid mode of electrical impulse propagation called saltatory conduction. The myelinated axons from the cortical neurons form the bulk of the neural tissue called white matter in the brain. The myelin gives the white appearance to the tissue in contrast to the grey matter of the cerebral cortex which contains the neuronal cell bodies. A similar arrangement is seen in the cerebellum. Bundles of myelinated axons make up the nerve tracts in the CNS. Where these tracts cross the midline of the brain to connect opposite regions they are called commissures. The largest of these is the corpus callosum that connects the two cerebral hemispheres, and this has around 20 million axons. The structure of a neuron is seen to consist of two separate functional regions, or compartmentsthe cell body together with the dendrites as one region, and the axonal region as the other. Axonal region The axonal region or compartment, includes the axon hillock, the initial segment, the rest of the axon, and the axon telodendria, and axon terminals. It also includes the myelin sheath. The Nissl bodies that produce the neuronal proteins are absent in the axonal region. Proteins needed for the growth of the axon, and the removal of waste materials, need a framework for transport. This axonal transport is provided for in the axoplasm by arrangements of microtubules and intermediate filaments known as neurofilaments. Axon hillock The axon hillock is the area formed from the cell body of the neuron as it extends to become the axon. It precedes the initial segment. The received action potentials that are summed in the neuron are transmitted to the axon hillock for the generation of an action potential from the initial segment. Axonal initial segment The axonal initial segment (AIS) is a structurally and functionally separate microdomain of the axon. One function of the initial segment is to separate the main part of an axon from the rest of the neuron; another function is to help initiate action potentials. Both of these functions support neuron cell polarity, in which dendrites (and, in some cases the soma) of a neuron receive input signals at the basal region, and at the apical region the neuron's axon provides output signals. The axon initial segment is unmyelinated and contains a specialized complex of proteins. It is between approximately 20 and 60 µm in length and functions as the site of action potential initiation. Both the position on the axon and the length of the AIS can change showing a degree of plasticity that can fine-tune the neuronal output. A longer AIS is associated with a greater excitability. Plasticity is also seen in the ability of the AIS to change its distribution and to maintain the activity of neural circuitry at a constant level. The AIS is highly specialized for the fast conduction of nerve impulses. This is achieved by a high concentration of voltage-gated sodium channels in the initial segment where the action potential is initiated. The ion channels are accompanied by a high number of cell adhesion molecules and scaffolding proteins that anchor them to the cytoskeleton. Interactions with ankyrin G are important as it is the major organizer in the AIS. Axonal transport The axoplasm is the equivalent of cytoplasm in the cell. Microtubules form in the axoplasm at the axon hillock. They are arranged along the length of the axon, in overlapping sections, and all point in the same directiontowards the axon terminals. This is noted by the positive endings of the microtubules. This overlapping arrangement provides the routes for the transport of different materials from the cell body. Studies on the axoplasm has shown the movement of numerous vesicles of all sizes to be seen along cytoskeletal filamentsthe microtubules, and neurofilaments, in both directions between the axon and its terminals and the cell body. Outgoing anterograde transport from the cell body along the axon, carries mitochondria and membrane proteins needed for growth to the axon terminal. Ingoing retrograde transport carries cell waste materials from the axon terminal to the cell body. Outgoing and ingoing tracks use different sets of motor proteins. Outgoing transport is provided by kinesin, and ingoing return traffic is provided by dynein. Dynein is minus-end directed. There are many forms of kinesin and dynein motor proteins, and each is thought to carry a different cargo. The studies on transport in the axon led to the naming of kinesin. Myelination In the nervous system, axons may be myelinated, or unmyelinated. This is the provision of an insulating layer, called a myelin sheath. The myelin membrane is unique in its relatively high lipid to protein ratio. In the peripheral nervous system axons are myelinated by glial cells known as Schwann cells. In the central nervous system the myelin sheath is provided by another type of glial cell, the oligodendrocyte. Schwann cells myelinate a single axon. An oligodendrocyte can myelinate up to 50 axons. The composition of myelin is different in the two types. In the CNS the major myelin protein is proteolipid protein, and in the PNS it is myelin basic protein. Nodes of Ranvier Nodes of Ranvier (also known as myelin sheath gaps) are short unmyelinated segments of a myelinated axon, which are found periodically interspersed between segments of the myelin sheath. Therefore, at the point of the node of Ranvier, the axon is reduced in diameter. These nodes are areas where action potentials can be generated. In saltatory conduction, electrical currents produced at each node of Ranvier are conducted with little attenuation to the next node in line, where they remain strong enough to generate another action potential. Thus in a myelinated axon, action potentials effectively "jump" from node to node, bypassing the myelinated stretches in between, resulting in a propagation speed much faster than even the fastest unmyelinated axon can sustain. Axon terminals An axon can divide into many branches called telodendria (Greek for 'end of tree'). At the end of each telodendron is an axon terminal (also called a synaptic bouton, or terminal bouton). Axon terminals contain synaptic vesicles that store the neurotransmitter for release at the synapse. This makes multiple synaptic connections with other neurons possible. Sometimes the axon of a neuron may synapse onto dendrites of the same neuron, when it is known as an autapse. Action potentials Most axons carry signals in the form of action potentials, which are discrete electrochemical impulses that travel rapidly along an axon, starting at the cell body and terminating at points where the axon makes synaptic contact with target cells. The defining characteristic of an action potential is that it is "all-or-nothing"every action potential that an axon generates has essentially the same size and shape. This all-or-nothing characteristic allows action potentials to be transmitted from one end of a long axon to the other without any reduction in size. There are, however, some types of neurons with short axons that carry graded electrochemical signals, of variable amplitude. When an action potential reaches a presynaptic terminal, it activates the synaptic transmission process. The first step is rapid opening of calcium ion channels in the membrane of the axon, allowing calcium ions to flow inward across the membrane. The resulting increase in intracellular calcium concentration causes synaptic vesicles (tiny containers enclosed by a lipid membrane) filled with a neurotransmitter chemical to fuse with the axon's membrane and empty their contents into the extracellular space. The neurotransmitter is released from the presynaptic nerve through exocytosis. The neurotransmitter chemical then diffuses across to receptors located on the membrane of the target cell. The neurotransmitter binds to these receptors and activates them. Depending on the type of receptors that are activated, the effect on the target cell can be to excite the target cell, inhibit it, or alter its metabolism in some way. This entire sequence of events often takes place in less than a thousandth of a second. Afterward, inside the presynaptic terminal, a new set of vesicles is moved into position next to the membrane, ready to be released when the next action potential arrives. The action potential is the final electrical step in the integration of synaptic messages at the scale of the neuron. Extracellular recordings of action potential propagation in axons has been demonstrated in freely moving animals. While extracellular somatic action potentials have been used to study cellular activity in freely moving animals such as place cells, axonal activity in both white and gray matter can also be recorded. Extracellular recordings of axon action potential propagation is distinct from somatic action potentials in three ways: 1. The signal has a shorter peak-trough duration (~150μs) than of pyramidal cells (~500μs) or interneurons (~250μs). 2. The voltage change is triphasic. 3. Activity recorded on a tetrode is seen on only one of the four recording wires. In recordings from freely moving rats, axonal signals have been isolated in white matter tracts including the alveus and the corpus callosum as well hippocampal gray matter. In fact, the generation of action potentials in vivo is sequential in nature, and these sequential spikes constitute the digital codes in the neurons. Although previous studies indicate an axonal origin of a single spike evoked by short-term pulses, physiological signals in vivo trigger the initiation of sequential spikes at the cell bodies of the neurons. In addition to propagating action potentials to axonal terminals, the axon is able to amplify the action potentials, which makes sure a secure propagation of sequential action potentials toward the axonal terminal. In terms of molecular mechanisms, voltage-gated sodium channels in the axons possess lower threshold and shorter refractory period in response to short-term pulses. Development and growth Development The development of the axon to its target, is one of the six major stages in the overall development of the nervous system. Studies done on cultured hippocampal neurons suggest that neurons initially produce multiple neurites that are equivalent, yet only one of these neurites is destined to become the axon. It is unclear whether axon specification precedes axon elongation or vice versa, although recent evidence points to the latter. If an axon that is not fully developed is cut, the polarity can change and other neurites can potentially become the axon. This alteration of polarity only occurs when the axon is cut at least 10 μm shorter than the other neurites. After the incision is made, the longest neurite will become the future axon and all the other neurites, including the original axon, will turn into dendrites. Imposing an external force on a neurite, causing it to elongate, will make it become an axon. Nonetheless, axonal development is achieved through a complex interplay between extracellular signaling, intracellular signaling and cytoskeletal dynamics. Extracellular signaling The extracellular signals that propagate through the extracellular matrix surrounding neurons play a prominent role in axonal development. These signaling molecules include proteins, neurotrophic factors, and extracellular matrix and adhesion molecules. Netrin (also known as UNC-6) a secreted protein, functions in axon formation. When the UNC-5 netrin receptor is mutated, several neurites are irregularly projected out of neurons and finally a single axon is extended anteriorly. The neurotrophic factorsnerve growth factor (NGF), brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NTF3) are also involved in axon development and bind to Trk receptors. The ganglioside-converting enzyme plasma membrane ganglioside sialidase (PMGS), which is involved in the activation of TrkA at the tip of neutrites, is required for the elongation of axons. PMGS asymmetrically distributes to the tip of the neurite that is destined to become the future axon. Intracellular signaling During axonal development, the activity of PI3K is increased at the tip of destined axon. Disrupting the activity of PI3K inhibits axonal development. Activation of PI3K results in the production of phosphatidylinositol (3,4,5)-trisphosphate (PtdIns) which can cause significant elongation of a neurite, converting it into an axon. As such, the overexpression of phosphatases that dephosphorylate PtdIns leads into the failure of polarization. Cytoskeletal dynamics The neurite with the lowest actin filament content will become the axon. PGMS concentration and f-actin content are inversely correlated; when PGMS becomes enriched at the tip of a neurite, its f-actin content is substantially decreased. In addition, exposure to actin-depolimerizing drugs and toxin B (which inactivates Rho-signaling) causes the formation of multiple axons. Consequently, the interruption of the actin network in a growth cone will promote its neurite to become the axon. Growth Growing axons move through their environment via the growth cone, which is at the tip of the axon. The growth cone has a broad sheet-like extension called a lamellipodium which contain protrusions called filopodia. The filopodia are the mechanism by which the entire process adheres to surfaces and explores the surrounding environment. Actin plays a major role in the mobility of this system. Environments with high levels of cell adhesion molecules (CAMs) create an ideal environment for axonal growth. This seems to provide a "sticky" surface for axons to grow along. Examples of CAMs specific to neural systems include N-CAM, TAG-1an axonal glycoproteinand MAG, all of which are part of the immunoglobulin superfamily. Another set of molecules called extracellular matrix-adhesion molecules also provide a sticky substrate for axons to grow along. Examples of these molecules include laminin, fibronectin, tenascin, and perlecan. Some of these are surface bound to cells and thus act as short range attractants or repellents. Others are difusible ligands and thus can have long range effects. Cells called guidepost cells assist in the guidance of neuronal axon growth. These cells that help axon guidance, are typically other neurons that are sometimes immature. When the axon has completed its growth at its connection to the target, the diameter of the axon can increase by up to five times, depending on the speed of conduction required. It has also been discovered through research that if the axons of a neuron were damaged, as long as the soma (the cell body of a neuron) is not damaged, the axons would regenerate and remake the synaptic connections with neurons with the help of guidepost cells. This is also referred to as neuroregeneration. Nogo-A is a type of neurite outgrowth inhibitory component that is present in the central nervous system myelin membranes (found in an axon). It has a crucial role in restricting axonal regeneration in adult mammalian central nervous system. In recent studies, if Nogo-A is blocked and neutralized, it is possible to induce long-distance axonal regeneration which leads to enhancement of functional recovery in rats and mouse spinal cord. This has yet to be done on humans. A recent study has also found that macrophages activated through a specific inflammatory pathway activated by the Dectin-1 receptor are capable of promoting axon recovery, also however causing neurotoxicity in the neuron. Length regulation Axons vary largely in length from a few micrometers up to meters in some animals. This emphasizes that there must be a cellular length regulation mechanism allowing the neurons both to sense the length of their axons and to control their growth accordingly. It was discovered that motor proteins play an important role in regulating the length of axons. Based on this observation, researchers developed an explicit model for axonal growth describing how motor proteins could affect the axon length on the molecular level. These studies suggest that motor proteins carry signaling molecules from the soma to the growth cone and vice versa whose concentration oscillates in time with a length-dependent frequency. Classification The axons of neurons in the human peripheral nervous system can be classified based on their physical features and signal conduction properties. Axons were known to have different thicknesses (from 0.1 to 20 µm) and these differences were thought to relate to the speed at which an action potential could travel along the axonits conductance velocity. Erlanger and Gasser proved this hypothesis, and identified several types of nerve fiber, establishing a relationship between the diameter of an axon and its nerve conduction velocity. They published their findings in 1941 giving the first classification of axons. Axons are classified in two systems. The first one introduced by Erlanger and Gasser, grouped the fibers into three main groups using the letters A, B, and C. These groups, group A, group B, and group C include both the sensory fibers (afferents) and the motor fibers (efferents). The first group A, was subdivided into alpha, beta, gamma, and delta fibersAα, Aβ, Aγ, and Aδ. The motor neurons of the different motor fibers, were the lower motor neuronsalpha motor neuron, beta motor neuron, and gamma motor neuron having the Aα, Aβ, and Aγ nerve fibers, respectively. Later findings by other researchers identified two groups of Aa fibers that were sensory fibers. These were then introduced into a system that only included sensory fibers (though some of these were mixed nerves and were also motor fibers). This system refers to the sensory groups as Types and uses Roman numerals: Type Ia, Type Ib, Type II, Type III, and Type IV. Motor Lower motor neurons have two kind of fibers: Different sensory receptors innervate different types of nerve fibers. Proprioceptors are innervated by type Ia, Ib and II sensory fibers, mechanoreceptors by type II and III sensory fibers and nociceptors and thermoreceptors by type III and IV sensory fibers. Autonomic The autonomic nervous system has two kinds of peripheral fibers: Clinical significance In order of degree of severity, injury to a nerve can be described as neurapraxia, axonotmesis, or neurotmesis. Concussion is considered a mild form of diffuse axonal injury. Axonal injury can also cause central chromatolysis. The dysfunction of axons in the nervous system is one of the major causes of many inherited neurological disorders that affect both peripheral and central neurons. When an axon is crushed, an active process of axonal degeneration takes place at the part of the axon furthest from the cell body. This degeneration takes place quickly following the injury, with the part of the axon being sealed off at the membranes and broken down by macrophages. This is known as Wallerian degeneration. Dying back of an axon can also take place in many neurodegenerative diseases, particularly when axonal transport is impaired, this is known as Wallerian-like degeneration. Studies suggest that the degeneration happens as a result of the axonal protein NMNAT2, being prevented from reaching all of the axon. Demyelination of axons causes the multitude of neurological symptoms found in the disease multiple sclerosis. Dysmyelination is the abnormal formation of the myelin sheath. This is implicated in several leukodystrophies, and also in schizophrenia. A severe traumatic brain injury can result in widespread lesions to nerve tracts damaging the axons in a condition known as diffuse axonal injury. This can lead to a persistent vegetative state. It has been shown in studies on the rat that axonal damage from a single mild traumatic brain injury, can leave a susceptibility to further damage, after repeated mild traumatic brain injuries. A nerve guidance conduit is an artificial means of guiding axon growth to enable neuroregeneration, and is one of the many treatments used for different kinds of nerve injury. History German anatomist Otto Friedrich Karl Deiters is generally credited with the discovery of the axon by distinguishing it from the dendrites. Swiss Rüdolf Albert von Kölliker and German Robert Remak were the first to identify and characterize the axon initial segment. Kölliker named the axon in 1896. Louis-Antoine Ranvier was the first to describe the gaps or nodes found on axons and for this contribution these axonal features are now commonly referred to as the nodes of Ranvier. Santiago Ramón y Cajal, a Spanish anatomist, proposed that axons were the output components of neurons, describing their functionality. Joseph Erlanger and Herbert Gasser earlier developed the classification system for peripheral nerve fibers, based on axonal conduction velocity, myelination, fiber size etc. Alan Hodgkin and Andrew Huxley also employed the squid giant axon (1939) and by 1952 they had obtained a full quantitative description of the ionic basis of the action potential, leading to the formulation of the Hodgkin–Huxley model. Hodgkin and Huxley were awarded jointly the Nobel Prize for this work in 1963. The formulae detailing axonal conductance were extended to vertebrates in the Frankenhaeuser–Huxley equations. The understanding of the biochemical basis for action potential propagation has advanced further, and includes many details about individual ion channels. Other animals The axons in invertebrates have been extensively studied. The longfin inshore squid, often used as a model organism has the longest known axon. The giant squid has the largest axon known. Its size ranges from 0.5 (typically) to 1 mm in diameter and is used in the control of its jet propulsion system. The fastest recorded conduction speed of 210 m/s, is found in the ensheathed axons of some pelagic Penaeid shrimps and the usual range is between 90 and 200 meters/s (cf 100–120 m/s for the fastest myelinated vertebrate axon.) In other cases as seen in rat studies an axon originates from a dendrite; such axons are said to have "dendritic origin". Some axons with dendritic origin similarly have a "proximal" initial segment that starts directly at the axon origin, while others have a "distal" initial segment, discernibly separated from the axon origin. In many species some of the neurons have axons that emanate from the dendrite and not from the cell body, and these are known as axon-carrying dendrites. In many cases, an axon originates at an axon hillock on the soma; such axons are said to have "somatic origin". Some axons with somatic origin have a "proximal" initial segment adjacent the axon hillock, while others have a "distal" initial segment, separated from the soma by an extended axon hillock.

"American shot" or "cowboy shot" is a translation of a phrase from French film criticism, , and refers to a medium-long ("knee") film shot of a group of characters, who are arranged so that all are visible to the camera. The usual arrangement is for the actors to stand in an irregular line from one side of the screen to the other, with the actors at the end coming forward a little and standing more in profile than the others. The purpose of the composition is to allow complex dialogue scenes to be played out without changes in camera position. In some literature, this is simply referred to as a 3/4 shot. One of the other main reasons why French critics called it "American shot" was its frequent use in the western genre. This was because a shot that started at knee level would reveal the weapon of a cowboy, usually holstered at their waist. It is actually the closest the camera can get to an actor while keeping both their face and their holstered gun in frame. The French critics thought it was characteristic of American films of the 1930s or 1940s; however, it was mostly characteristic of cheaper American movies, such as Charlie Chan mysteries where people collected in front of a fireplace or at the foot of the stairs in order to explain what happened a few minutes ago. Howard Hawks legitimized this style in his films, allowing characters to act, even when not talking, when most of the audience would not be paying attention. It became his trademark style.

Acute disseminated encephalomyelitis

Acute disseminated encephalomyelitis (ADEM), or acute demyelinating encephalomyelitis, is a rare autoimmune disease marked by a sudden, widespread attack of inflammation in the brain and spinal cord. As well as causing the brain and spinal cord to become inflamed, ADEM also attacks the nerves of the central nervous system and damages their myelin insulation, which, as a result, destroys the white matter. It is often triggered by a viral infection or vaccinations. ADEM's symptoms resemble the symptoms of multiple sclerosis (MS), so the disease itself is sorted into the classification of the multiple sclerosis borderline diseases. However, ADEM has several features that distinguish it from MS. Unlike MS, ADEM occurs usually in children and is marked with rapid fever, although adolescents and adults can get the disease too. ADEM consists of a single flare-up whereas MS is marked with several flare-ups (or relapses), over a long period of time. Relapses following ADEM are reported in up to a quarter of patients, but the majority of these 'multiphasic' presentations following ADEM likely represent MS. ADEM is also distinguished by a loss of consciousness, coma and death, which is very rare in MS, except in severe cases. It affects about 8 per 1,000,000 people per year. Although it occurs in all ages, most reported cases are in children and adolescents, with the average age around 5 to 8 years old. The disease affects males and females almost equally. ADEM shows seasonal variation with higher incidence in winter and spring months which may coincide with higher viral infections during these months. The mortality rate may be as high as 5%; however, full recovery is seen in 50 to 75% of cases with increase in survival rates up to 70 to 90% with figures including minor residual disability as well. The average time to recover from ADEM flare-ups is one to six months. ADEM produces multiple inflammatory lesions in the brain and spinal cord, particularly in the white matter. Usually these are found in the subcortical and central white matter and cortical gray-white junction of both cerebral hemispheres, cerebellum, brainstem, and spinal cord, but periventricular white matter and gray matter of the cortex, thalami and basal ganglia may also be involved. When a person has more than one demyelinating episode of ADEM, the disease is then called recurrent disseminated encephalomyelitis or multiphasic disseminated encephalomyelitis (MDEM). Also, a fulminant course in adults has been described. Signs and symptoms ADEM has an abrupt onset and a monophasic course. Symptoms usually begin 1–3 weeks after infection. Major symptoms include fever, headache, nausea and vomiting, confusion, vision impairment, drowsiness, seizures and coma. Although initially the symptoms are usually mild, they worsen rapidly over the course of hours to days, with the average time to maximum severity being about four and a half days. Additional symptoms include hemiparesis, paraparesis, and cranial nerve palsies. ADEM in COVID-19 Neurological symptoms were the main presentation of COVID-19, which did not correlate with the severity of respiratory symptoms. The high incidence of ADEM with hemorrhage is striking. Brain inflammation is likely caused by an immune response to the disease rather than neurotropism. CSF analysis was not indicative of an infectious process, neurological impairment was not present in the acute phase of the infection, and neuroimaging findings were not typical of classical toxic and metabolic disorders. The finding of bilateral periventricular relatively asymmetrical lesions allied with deep white matter involvement, that may also be present in cortical gray-white matter junction, thalami, basal ganglia, cerebellum, and brainstem suggests an acute demyelination process. Additionally, hemorrhagic white matter lesions, clusters of macrophages related to axonal injury and ADEM-like appearance were also found in subcortical white matter. Causes Since the discovery of the anti-MOG specificity against multiple sclerosis diagnosis it is considered that ADEM is one of the possible clinical causes of anti-MOG associated encephalomyelitis. About how the anti-MOG antibodies appear in the patients serum there are several theories: A preceding antigenic challenge can be identified in approximately two-thirds of people. Some viral infections thought to induce ADEM include influenza virus, dengue, enterovirus, measles, mumps, rubella, varicella zoster, Epstein–Barr virus, cytomegalovirus, herpes simplex virus, hepatitis A, coxsackievirus and COVID-19. Bacterial infections include Mycoplasma pneumoniae, Borrelia burgdorferi, Leptospira, and beta-hemolytic Streptococci. Exposure to vaccines: The only vaccine proven related to ADEM is the Semple form of the rabies vaccine, but hepatitis B, pertussis, diphtheria, measles, mumps, rubella, pneumococcus, varicella, influenza, Japanese encephalitis, and polio vaccines have all been implicated. The majority of the studies that correlate vaccination with ADEM onset use small samples or case studies. Large scale epidemiological studies (e.g., of MMR vaccine or smallpox vaccine) do not show increased risk of ADEM following vaccination. An upper bound for the risk of ADEM from measles vaccination, if it exists, can be estimated to be 10 per million, which is far lower than the risk of developing ADEM from an actual measles infection, which is about 1 per 1,000 cases. For a rubella infection, the risk is 1 per 5,000 cases. Some early vaccines, later shown to have been contaminated with host animal CNS tissue, had ADEM incident rates as high as 1 in 600. In rare cases, ADEM seems to follow from organ transplantation. Diagnosis ADEM term has been inconsistently used at different times. Currently, the commonly accepted international standard for the clinical case definition is the one published by the International Pediatric MS Study Group, revision 2007. Given that the definition is clinical, it is currently unknown if all the cases with ADEM are positive for anti-MOG autoantibody, but in any case, it seems strongly related to ADEM diagnosis. Differential diagnosis Multiple sclerosis While ADEM and MS both involve autoimmune demyelination, they differ in many clinical, genetic, imaging, and histopathological aspects. Some authors consider MS and its borderline forms to constitute a spectrum, differing only in chronicity, severity, and clinical course, while others consider them discretely different diseases. Typically, ADEM appears in children following an antigenic challenge and remains monophasic. Nevertheless, ADEM does occur in adults, and can also be clinically multiphasic. Problems for differential diagnosis increase due to the lack of agreement for a definition of multiple sclerosis. If MS were defined just by the separation in time and space of the demyelinating lesions as McDonald did, it would not be enough to make a difference, as some cases of ADEM satisfy these conditions. Therefore, some authors propose to establish the separation line in the shape of the lesions around the veins, being therefore "perivenous vs. confluent demyelination". The pathology of ADEM is very similar to that of MS with some differences. The pathological hallmark of ADEM is perivenular inflammation with limited "sleeves of demyelination". Nevertheless, MS-like plaques (confluent demyelination) can appear Plaques in the white matter in MS are sharply delineated, while the glial scar in ADEM is smooth. Axons are better preserved in ADEM lesions. Inflammation in ADEM is widely disseminated and ill-defined, and finally, lesions are strictly perivenous, while in MS they are disposed around veins, but not so sharply. Nevertheless, the co-occurrence of perivenous and confluent demyelination in some individuals suggests pathogenic overlap between acute disseminated encephalomyelitis and multiple sclerosis and misclassification even with biopsy or even postmortem ADEM in adults can progress to MS Multiphasic disseminated encephalomyelitis When the person has more than one demyelinating episode of ADEM, the disease is then called recurrent disseminated encephalomyelitis or multiphasic disseminated encephalomyelitis (MDEM). It has been found that anti-MOG auto-antibodies are related to this kind of ADEM Another variant of ADEM in adults has been described, also related to anti-MOG auto-antibodies, has been named fulminant disseminated encephalomyelitis, and it has been reported to be clinically ADEM, but showing MS-like lesions on autopsy. It has been classified inside the anti-MOG associated inflammatory demyelinating diseases. Acute hemorrhagic leukoencephalitis Acute hemorrhagic leukoencephalitis (AHL, or AHLE), acute hemorrhagic encephalomyelitis (AHEM), acute necrotizing hemorrhagic leukoencephalitis (ANHLE), Weston-Hurst syndrome, or Hurst's disease, is a hyperacute and frequently fatal form of ADEM. AHL is relatively rare (less than 100 cases have been reported in the medical literature ), it is seen in about 2% of ADEM cases, and is characterized by necrotizing vasculitis of venules and hemorrhage, and edema. Death is common in the first week and overall mortality is about 70%, but increasing evidence points to favorable outcomes after aggressive treatment with corticosteroids, immunoglobulins, cyclophosphamide, and plasma exchange. About 70% of survivors show residual neurological deficits, but some survivors have shown surprisingly little deficit considering the magnitude of the white matter affected. This disease has been occasionally associated with ulcerative colitis and Crohn's disease, malaria, sepsis associated with immune complex deposition, methanol poisoning, and other underlying conditions. Also anecdotal association with MS has been reported Laboratory studies that support diagnosis of AHL are: peripheral leukocytosis, cerebrospinal fluid (CSF) pleocytosis associated with normal glucose and increased protein. On magnetic resonance imaging (MRI), lesions of AHL typically show extensive T2-weighted and fluid-attenuated inversion recovery (FLAIR) white matter hyperintensities with areas of hemorrhages, significant edema, and mass effect. Treatment No controlled clinical trials have been conducted on ADEM treatment, but aggressive treatment aimed at rapidly reducing inflammation of the CNS is standard. The widely accepted first-line treatment is high doses of intravenous corticosteroids, such as methylprednisolone or dexamethasone, followed by 3–6 weeks of gradually lower oral doses of prednisolone. Patients treated with methylprednisolone have shown better outcomes than those treated with dexamethasone. Oral tapers of less than three weeks duration show a higher chance of relapsing, and tend to show poorer outcomes. Other anti-inflammatory and immunosuppressive therapies have been reported to show beneficial effect, such as plasmapheresis, high doses of intravenous immunoglobulin (IVIg), mitoxantrone and cyclophosphamide. These are considered alternative therapies, used when corticosteroids cannot be used or fail to show an effect. There is some evidence to suggest that patients may respond to a combination of methylprednisolone and immunoglobulins if they fail to respond to either separately In a study of 16 children with ADEM, 10 recovered completely after high-dose methylprednisolone, one severe case that failed to respond to steroids recovered completely after IV Ig; the five most severe cases – with ADAM and severe peripheral neuropathy – were treated with combined high-dose methylprednisolone and immunoglobulin, two remained paraplegic, one had motor and cognitive handicaps, and two recovered. A recent review of IVIg treatment of ADEM (of which the previous study formed the bulk of the cases) found that 70% of children showed complete recovery after treatment with IVIg, or IVIg plus corticosteroids. A study of IVIg treatment in adults with ADEM showed that IVIg seems more effective in treating sensory and motor disturbances, while steroids seem more effective in treating impairments of cognition, consciousness and rigor. This same study found one subject, a 71-year-old man who had not responded to steroids, that responded to an IVIg treatment 58 days after disease onset. Prognosis Full recovery is seen in 50 to 70% of cases, ranging to 70 to 90% recovery with some minor residual disability (typically assessed using measures such as mRS or EDSS), average time to recover is one to six months. The mortality rate may be as high as 5–10%. Poorer outcomes are associated with unresponsiveness to steroid therapy, unusually severe neurological symptoms, or sudden onset. Children tend to have more favorable outcomes than adults, and cases presenting without fevers tend to have poorer outcomes. The latter effect may be due to either protective effects of fever, or that diagnosis and treatment is sought more rapidly when fever is present. ADEM can progress to MS. It will be considered MS if some lesions appear in different times and brain areas Motor deficits Residual motor deficits are estimated to remain in about 8 to 30% of cases, the range in severity from mild clumsiness to ataxia and hemiparesis. Neurocognitive Patients with demyelinating illnesses, such as MS, have shown cognitive deficits even when there is minimal physical disability. Research suggests that similar effects are seen after ADEM, but that the deficits are less severe than those seen in MS. A study of six children with ADEM (mean age at presentation 7.7 years) were tested for a range of neurocognitive tests after an average of 3.5 years of recovery. All six children performed in the normal range on most tests, including verbal IQ and performance IQ, but performed at least one standard deviation below age norms in at least one cognitive domain, such as complex attention (one child), short-term memory (one child) and internalizing behaviour/affect (two children). Group means for each cognitive domain were all within one standard deviation of age norms, demonstrating that, as a group, they were normal. These deficits were less severe than those seen in similar aged children with a diagnosis of MS. Another study compared nineteen children with a history of ADEM, of which 10 were five years of age or younger at the time (average age 3.8 years old, tested an average of 3.9 years later) and nine were older (mean age 7.7y at time of ADEM, tested an average of 2.2 years later) to nineteen matched controls. Scores on IQ tests and educational achievement were lower for the young onset ADEM group (average IQ 90) compared to the late onset (average IQ 100) and control groups (average IQ 106), while the late onset ADEM children scored lower on verbal processing speed. Again, all groups means were within one standard deviation of the controls, meaning that while effects were statistically reliable, the children were as a whole, still within the normal range. There were also more behavioural problems in the early onset group, although there is some suggestion that this may be due, at least in part, to the stress of hospitalization at a young age. Research The relationship between ADEM and anti-MOG associated encephalomyelitis is currently under research. A new entity called MOGDEM has been proposed. About animal models, the main animal model for MS, experimental autoimmune encephalomyelitis (EAE) is also an animal model for ADEM. Being an acute monophasic illness, EAE is far more similar to ADEM than MS.

Ada Lovelace

Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and to have published the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first computer programmer. Ada Byron was the only legitimate child of poet Lord Byron and Lady Byron. All of Byron's other children were born out of wedlock to other women. Byron separated from his wife a month after Ada was born and left England forever. Four months later, he commemorated the parting in a poem that begins, "Is thy face like thy mother's my fair child! ADA! sole daughter of my house and heart?" He died in Greece when Ada was eight. Her mother remained bitter and promoted Ada's interest in mathematics and logic in an effort to prevent her from developing her father's perceived insanity. Despite this, Ada remained interested in him, naming her two sons Byron and Gordon. Upon her death, she was buried next to him at her request. Although often ill in her childhood, Ada pursued her studies assiduously. She married William King in 1835. King was made Earl of Lovelace in 1838, Ada thereby becoming Countess of Lovelace. Her educational and social exploits brought her into contact with scientists such as Andrew Crosse, Charles Babbage, Sir David Brewster, Charles Wheatstone, Michael Faraday, and the author Charles Dickens, contacts which she used to further her education. Ada described her approach as "poetical science" and herself as an "Analyst (& Metaphysician)". When she was eighteen, her mathematical talents led her to a long working relationship and friendship with fellow British mathematician Charles Babbage, who is known as "the father of computers". She was in particular interested in Babbage's work on the Analytical Engine. Lovelace first met him in June 1833, through their mutual friend, and her private tutor, Mary Somerville. Between 1842 and 1843, Ada translated an article by Italian military engineer Luigi Menabrea about the Analytical Engine, supplementing it with an elaborate set of notes, simply called "Notes". Lovelace's notes are important in the early history of computers, containing what many consider to be the first computer program—that is, an algorithm designed to be carried out by a machine. Other historians reject this perspective and point out that Babbage's personal notes from the years 1836/1837 contain the first programs for the engine. She also developed a vision of the capability of computers to go beyond mere calculating or number-crunching, while many others, including Babbage himself, focused only on those capabilities. Her mindset of "poetical science" led her to ask questions about the Analytical Engine (as shown in her notes) examining how individuals and society relate to technology as a collaborative tool. Biography Childhood Lord Byron expected his child to be a "glorious boy" and was disappointed when Lady Byron gave birth to a girl. The child was named after Byron's half-sister, Augusta Leigh, and was called "Ada" by Byron himself. On 16 January 1816, at Lord Byron's command, Lady Byron left for her parents' home at Kirkby Mallory, taking their five-week-old daughter with her. Although English law at the time granted full custody of children to the father in cases of separation, Lord Byron made no attempt to claim his parental rights, but did request that his sister keep him informed of Ada's welfare. On 21 April, Lord Byron signed the deed of separation, although very reluctantly, and left England for good a few days later. Aside from an acrimonious separation, Lady Byron continued throughout her life to make allegations about her husband's immoral behaviour. This set of events made Lovelace infamous in Victorian society. Ada did not have a relationship with her father. He died in 1824 when she was eight years old. Her mother was the only significant parental figure in her life. Lovelace was not shown the family portrait of her father until her 20th birthday. Lovelace did not have a close relationship with her mother. She was often left in the care of her maternal grandmother Judith, Hon. Lady Milbanke, who doted on her. However, because of societal attitudes of the time—which favoured the husband in any separation, with the welfare of any child acting as mitigation—Lady Byron had to present herself as a loving mother to the rest of society. This included writing anxious letters to Lady Milbanke about her daughter's welfare, with a cover note saying to retain the letters in case she had to use them to show maternal concern. In one letter to Lady Milbanke, she referred to her daughter as "it": "I talk to it for your satisfaction, not my own, and shall be very glad when you have it under your own." Lady Byron had her teenage daughter watched by close friends for any sign of moral deviation. Lovelace dubbed these observers the "Furies" and later complained they exaggerated and invented stories about her. Lovelace was often ill, beginning in early childhood. At the age of eight, she experienced headaches that obscured her vision. In June 1829, she was paralyzed after a bout of measles. She was subjected to continuous bed rest for nearly a year, something which may have extended her period of disability. By 1831, she was able to walk with crutches. Despite the illnesses, she developed her mathematical and technological skills. Ada Byron had an affair with a tutor in early 1833. She tried to elope with him after she was caught, but the tutor's relatives recognised her and contacted her mother. Lady Byron and her friends covered the incident up to prevent a public scandal. Lovelace never met her younger half-sister, Allegra, the daughter of Lord Byron and Claire Clairmont. Allegra died in 1822 at the age of five. Lovelace did have some contact with Elizabeth Medora Leigh, the daughter of Byron's half-sister Augusta Leigh, who purposely avoided Lovelace as much as possible when introduced at court. Adult years Lovelace became close friends with her tutor Mary Somerville, who introduced her to Charles Babbage in 1833. She had a strong respect and affection for Somerville, and they corresponded for many years. Other acquaintances included the scientists Andrew Crosse, Sir David Brewster, Charles Wheatstone, Michael Faraday and the author Charles Dickens. She was presented at Court at the age of seventeen "and became a popular belle of the season" in part because of her "brilliant mind". By 1834 Ada was a regular at Court and started attending various events. She danced often and was able to charm many people, and was described by most people as being dainty, although John Hobhouse, Byron's friend, described her as "a large, coarse-skinned young woman but with something of my friend's features, particularly the mouth". This description followed their meeting on 24 February 1834 in which Ada made it clear to Hobhouse that she did not like him, probably due to her mother's influence, which led her to dislike all of her father's friends. This first impression was not to last, and they later became friends. On 8 July 1835, she married William, 8th Baron King, becoming Lady King. They had three homes: Ockham Park, Surrey; a Scottish estate on Loch Torridon in Ross-shire; and a house in London. They spent their honeymoon at Worthy Manor in Ashley Combe near Porlock Weir, Somerset. The Manor had been built as a hunting lodge in 1799 and was improved by King in preparation for their honeymoon. It later became their summer retreat and was further improved during this time. From 1845, the family's main house was Horsley Towers, built in the Tudorbethan fashion by the architect of the Houses of Parliament, Charles Barry, and later greatly enlarged to Lovelace's own designs. They had three children: Byron (born 1836); Anne Isabella (called Annabella, born 1837); and Ralph Gordon (born 1839). Immediately after the birth of Annabella, Lady King experienced "a tedious and suffering illness, which took months to cure". Ada was a descendant of the extinct Barons Lovelace and in 1838, her husband was made Earl of Lovelace and Viscount Ockham, meaning Ada became the Countess of Lovelace. In 1843–44, Ada's mother assigned William Benjamin Carpenter to teach Ada's children and to act as a "moral" instructor for Ada. He quickly fell for her and encouraged her to express any frustrated affections, claiming that his marriage meant he would never act in an "unbecoming" manner. When it became clear that Carpenter was trying to start an affair, Ada cut it off. In 1841, Lovelace and Medora Leigh (the daughter of Lord Byron's half-sister Augusta Leigh) were told by Ada's mother that Ada's father was also Medora's father. On 27 February 1841, Ada wrote to her mother: "I am not in the least astonished. In fact, you merely confirm what I have for years and years felt scarcely a doubt about, but should have considered it most improper in me to hint to you that I in any way suspected." She did not blame the incestuous relationship on Byron, but instead blamed Augusta Leigh: "I fear she is more inherently wicked than he ever was." In the 1840s, Ada flirted with scandals: firstly, from a relaxed approach to extra-marital relationships with men, leading to rumours of affairs; and secondly, from her love of gambling. She apparently lost more than £3,000 on the horses during the later 1840s. The gambling led to her forming a syndicate with male friends, and an ambitious attempt in 1851 to create a mathematical model for successful large bets. This went disastrously wrong, leaving her thousands of pounds in debt to the syndicate, forcing her to admit it all to her husband. She had a shadowy relationship with Andrew Crosse's son John from 1844 onwards. John Crosse destroyed most of their correspondence after her death as part of a legal agreement. She bequeathed him the only heirlooms her father had personally left to her. During her final illness, she would panic at the idea of the younger Crosse being kept from visiting her. Education From 1832, when she was seventeen, her mathematical abilities began to emerge, and her interest in mathematics dominated the majority of her adult life. Her mother's obsession with rooting out any of the insanity of which she accused Byron was one of the reasons that Ada was taught mathematics from an early age. She was privately educated in mathematics and science by William Frend, William King, and Mary Somerville, the noted 19th-century researcher and scientific author. In the 1840s, the mathematician Augustus De Morgan extended her "much help in her mathematical studies" including study of advanced calculus topics including the "numbers of Bernoulli" (that formed her celebrated algorithm for Babbage's Analytical Engine). In a letter to Lady Byron, De Morgan suggested that Ada's skill in mathematics might lead her to become "an original mathematical investigator, perhaps of first-rate eminence". Lovelace often questioned basic assumptions through integrating poetry and science. Whilst studying differential calculus, she wrote to De Morgan: I may remark that the curious transformations many formulae can undergo, the unsuspected and to a beginner apparently impossible identity of forms exceedingly dissimilar at first sight, is I think one of the chief difficulties in the early part of mathematical studies. I am often reminded of certain sprites and fairies one reads of, who are at one's elbows in one shape now, and the next minute in a form most dissimilar. Lovelace believed that intuition and imagination were critical to effectively applying mathematical and scientific concepts. She valued metaphysics as much as mathematics, viewing both as tools for exploring "the unseen worlds around us". Death Lovelace died at the age of 36 on 27 November 1852, from uterine cancer. The illness lasted several months, in which time Annabella took command over whom Ada saw, and excluded all of her friends and confidants. Under her mother's influence, Ada had a religious transformation and was coaxed into repenting of her previous conduct and making Annabella her executor. She lost contact with her husband after confessing something to him on 30 August which caused him to abandon her bedside. It is not known what she told him. She was buried, at her request, next to her father at the Church of St. Mary Magdalene in Hucknall, Nottinghamshire. A memorial plaque, written in Latin, to her and her father is in the chapel attached to Horsley Towers. Work Throughout her life, Lovelace was strongly interested in scientific developments and fads of the day, including phrenology and mesmerism. After her work with Babbage, Lovelace continued to work on other projects. In 1844, she commented to a friend Woronzow Greig about her desire to create a mathematical model for how the brain gives rise to thoughts and nerves to feelings ("a calculus of the nervous system"). She never achieved this, however. In part, her interest in the brain came from a long-running pre-occupation, inherited from her mother, about her "potential" madness. As part of her research into this project, she visited the electrical engineer Andrew Crosse in 1844 to learn how to carry out electrical experiments. In the same year, she wrote a review of a paper by Baron Karl von Reichenbach, Researches on Magnetism, but this was not published and does not appear to have progressed past the first draft. In 1851, the year before her cancer struck, she wrote to her mother mentioning "certain productions" she was working on regarding the relation of maths and music. Lovelace first met Charles Babbage in June 1833, through their mutual friend Mary Somerville. Later that month, Babbage invited Lovelace to see the prototype for his difference engine. She became fascinated with the machine and used her relationship with Somerville to visit Babbage as often as she could. Babbage was impressed by Lovelace's intellect and analytic skills. He called her "The Enchantress of Number". In 1843, he wrote to her: During a nine-month period in 1842–43, Lovelace translated the Italian mathematician Luigi Menabrea's article on Babbage's newest proposed machine, the Analytical Engine. With the article, she appended a set of notes. Explaining the Analytical Engine's function was a difficult task; many other scientists did not grasp the concept and the British establishment had shown little interest in it. Lovelace's notes even had to explain how the Analytical Engine differed from the original Difference Engine. Her work was well received at the time; the scientist Michael Faraday described himself as a supporter of her writing. The notes are around three times longer than the article itself and include (in Note G), in complete detail, a method for calculating a sequence of Bernoulli numbers using the Analytical Engine, which might have run correctly had it ever been built (only Babbage's Difference Engine has been built, completed in London in 2002). Based on this work, Lovelace is now considered by many to be the first computer programmer and her method has been called the world's first computer program. Others dispute this because some of Charles Babbage's earlier writings could be considered computer programs. Note G also contains Lovelace's dismissal of artificial intelligence. She wrote that "The Analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to perform. It can follow analysis; but it has no power of anticipating any analytical relations or truths." This objection has been the subject of much debate and rebuttal, for example by Alan Turing in his paper "Computing Machinery and Intelligence". Most modern computer scientists argue that this view is outdated and that computer software can develop in ways that cannot necessarily be anticipated by programmers. Lovelace and Babbage had a minor falling out when the papers were published, when he tried to leave his own statement (criticising the government's treatment of his Engine) as an unsigned preface, which could have been mistakenly interpreted as a joint declaration. When Taylor's Scientific Memoirs ruled that the statement should be signed, Babbage wrote to Lovelace asking her to withdraw the paper. This was the first that she knew he was leaving it unsigned, and she wrote back refusing to withdraw the paper. The historian Benjamin Woolley theorised that "His actions suggested he had so enthusiastically sought Ada's involvement, and so happily indulged her ... because of her 'celebrated name'." Their friendship recovered, and they continued to correspond. On 12 August 1851, when she was dying of cancer, Lovelace wrote to him asking him to be her executor, though this letter did not give him the necessary legal authority. Part of the terrace at Worthy Manor was known as Philosopher's Walk; it was there that Lovelace and Babbage were reputed to have walked while discussing mathematical principles. First computer program In 1840, Babbage was invited to give a seminar at the University of Turin about his Analytical Engine. Luigi Menabrea, a young Italian engineer and the future Prime Minister of Italy, transcribed Babbage's lecture into French, and this transcript was subsequently published in the Bibliothèque universelle de Genève in October 1842. Babbage's friend Charles Wheatstone commissioned Ada Lovelace to translate Menabrea's paper into English. She then augmented the paper with notes, which were added to the translation. Ada Lovelace spent the better part of a year doing this, assisted with input from Babbage. These notes, which are more extensive than Menabrea's paper, were then published in the September 1843 edition of Taylor's Scientific Memoirs under the initialism AAL. Ada Lovelace's notes were labelled alphabetically from A to G. In note G, she describes an algorithm for the Analytical Engine to compute Bernoulli numbers. It is considered to be the first published algorithm ever specifically tailored for implementation on a computer, and Ada Lovelace has often been cited as the first computer programmer for this reason. The engine was never completed and so her program was never tested. In 1953, more than a century after her death, Ada Lovelace's notes on Babbage's Analytical Engine were republished as an appendix to B. V. Bowden's Faster than Thought: A Symposium on Digital Computing Machines. The engine has now been recognised as an early model for a computer and her notes as a description of a computer and software. Insight into potential of computing devices In her notes, Ada Lovelace emphasised the difference between the Analytical Engine and previous calculating machines, particularly its ability to be programmed to solve problems of any complexity. She realised the potential of the device extended far beyond mere number crunching. In her notes, she wrote: This analysis was an important development from previous ideas about the capabilities of computing devices and anticipated the implications of modern computing one hundred years before they were realised. Walter Isaacson ascribes Ada's insight regarding the application of computing to any process based on logical symbols to an observation about textiles: "When she saw some mechanical looms that used punchcards to direct the weaving of beautiful patterns, it reminded her of how Babbage's engine used punched cards to make calculations." This insight is seen as significant by writers such as Betty Toole and Benjamin Woolley, as well as the programmer John Graham-Cumming, whose project Plan 28 has the aim of constructing the first complete Analytical Engine. According to the historian of computing and Babbage specialist Doron Swade: Ada saw something that Babbage in some sense failed to see. In Babbage's world his engines were bound by number...What Lovelace saw...was that number could represent entities other than quantity. So once you had a machine for manipulating numbers, if those numbers represented other things, letters, musical notes, then the machine could manipulate symbols of which number was one instance, according to rules. It is this fundamental transition from a machine which is a number cruncher to a machine for manipulating symbols according to rules that is the fundamental transition from calculation to computation—to general-purpose computation—and looking back from the present high ground of modern computing, if we are looking and sifting history for that transition, then that transition was made explicitly by Ada in that 1843 paper. Distinction between mechanism and logical structure Lovelace recognized the difference between the details of the computing mechanism, as covered in a 1834 article on the Difference Engine, and the logical structure of the Analytical Engine, on which the article she was reviewing dwelt. She noted that different specialists might be required in each area. The [1834 article] chiefly treats it under its mechanical aspect, entering but slightly into the mathematical principles of which that engine is the representative, but giving, in considerable length, many details of the mechanism and contrivances by means of which it tabulates the various orders of differences. M. Menabrea, on the contrary, exclusively developes the analytical view; taking it for granted that mechanism is able to perform certain processes, but without attempting to explain how; and devoting his whole attention to explanations and illustrations of the manner in which analytical laws can be so arranged and combined as to bring every branch of that vast subject within the grasp of the assumed powers of mechanism. It is obvious that, in the invention of a calculating engine, these two branches of the subject are equally essential fields of investigation... They are indissolubly connected, though so different in their intrinsic nature, that perhaps the same mind might not be likely to prove equally profound or successful in both. Controversy over contribution Though Lovelace is often referred to as the first computer programmer, some biographers, computer scientists and historians of computing claim otherwise. Allan G. Bromley, in the 1990 article Difference and Analytical Engines: Bruce Collier, who later wrote a biography of Babbage, wrote in his 1970 Harvard University PhD thesis that Lovelace "made a considerable contribution to publicizing the Analytical Engine, but there is no evidence that she advanced the design or theory of it in any way". Eugene Eric Kim and Betty Alexandra Toole consider it "incorrect" to regard Lovelace as the first computer programmer, as Babbage wrote the initial programs for his Analytical Engine, although the majority were never published. Bromley notes several dozen sample programs prepared by Babbage between 1837 and 1840, all substantially predating Lovelace's notes. Dorothy K. Stein regards Lovelace's notes as "more a reflection of the mathematical uncertainty of the author, the political purposes of the inventor, and, above all, of the social and cultural context in which it was written, than a blueprint for a scientific development". Doron Swade, a specialist on history of computing known for his work on Babbage, discussed Lovelace during a lecture on Babbage's analytical engine. He explained that Ada was only a "promising beginner" instead of genius in mathematics, that she began studying basic concepts of mathematics five years after Babbage conceived the analytical engine so she could not have made important contributions to it, and that she only published the first computer program instead of actually writing it. But he agrees that Ada was the only person to see the potential of the analytical engine as a machine capable of expressing entities other than quantities. In his book, Idea Makers, Stephen Wolfram defends Lovelace's contributions. While acknowledging that Babbage wrote several unpublished algorithms for the Analytical Engine prior to Lovelace's notes, Wolfram argues that "there's nothing as sophisticated—or as clean—as Ada's computation of the Bernoulli numbers. Babbage certainly helped and commented on Ada's work, but she was definitely the driver of it." Wolfram then suggests that Lovelace's main achievement was to distill from Babbage's correspondence "a clear exposition of the abstract operation of the machine—something which Babbage never did". In popular culture 1810s Lord Byron wrote the poem "Fare Thee Well" to his wife Lady Byron in 1816, following their separation after the birth of Ada Lovelace. In the poem he writes: And when thou would'st solace gather— When our child's first accents flow— Wilt thou teach her to say "Father!" Though his care she must forego? When her little hands shall press thee— When her lip to thine is pressed— Think of him whose prayer shall bless thee— Think of him thy love had blessed! Should her lineaments resemble Those thou never more may'st see, Then thy heart will softly tremble With a pulse yet true to me. 1970s Lovelace is portrayed in Romulus Linney's 1977 play Childe Byron. 1990s In the 1990 steampunk novel The Difference Engine by William Gibson and Bruce Sterling, Lovelace delivers a lecture on the "punched cards" programme which proves Gödel's incompleteness theorems decades before their actual discovery. In the 1997 film Conceiving Ada, a computer scientist obsessed with Ada finds a way of communicating with her in the past by means of "undying information waves". In Tom Stoppard's 1993 play Arcadia, the precocious teenage genius Thomasina Coverly—a character "apparently based" on Ada Lovelace (the play also involves Lord Byron)—comes to understand chaos theory, and theorises the second law of thermodynamics, before either is officially recognised. 2000s Lovelace features in John Crowley's 2005 novel, Lord Byron's Novel: The Evening Land, as an unseen character whose personality is forcefully depicted in her annotations and anti-heroic efforts to archive her father's lost novel. 2010s The 2015 play Ada and the Engine by Lauren Gunderson portrays Lovelace and Charles Babbage in unrequited love, and it imagines a post-death meeting between Lovelace and her father. Lovelace and Babbage are the main characters in Sydney Padua's webcomic and graphic novel The Thrilling Adventures of Lovelace and Babbage. The comic features extensive footnotes on the history of Ada Lovelace, and many lines of dialogue are drawn from actual correspondence. Lovelace and Mary Shelley as teenagers are the central characters in Jordan Stratford's steampunk series, The Wollstonecraft Detective Agency. Lovelace, identified as Ada Augusta Byron, is portrayed by Lily Lesser in the second season of The Frankenstein Chronicles. She is employed as an "analyst" to provide the workings of a life-sized humanoid automaton. The brass workings of the machine are reminiscent of Babbage's analytical engine. Her employment is described as keeping her occupied until she returns to her studies in advanced mathematics. Lovelace and Babbage appear as characters in the second season of the ITV series Victoria (2017). Emerald Fennell portrays Lovelace in the episode, "The Green-Eyed Monster." The Cardano cryptocurrency platform, which was launched in 2017, uses Ada as the name for their cryptocurrency and Lovelace as the smallest sub-unit of an Ada. "Lovelace" is the name given to the operating system designed by the character Cameron Howe in Halt and Catch Fire. Lovelace is a primary character in the 2019 Big Finish Doctor Who audio play The Enchantress of Numbers, starring Tom Baker as the Fourth Doctor and Jane Slavin as his current companion, WPC Ann Kelso. Lovelace is played by Finty Williams. In 2019, Lovelace is a featured character in the play STEM FEMMES by Philadelphia theater company Applied Mechanics. 2020s Lovelace features as a character in "Spyfall, Part 2", the second episode of Doctor Who, series 12, which first aired on BBC One on 5 January 2020. The character was portrayed by Sylvie Briggs, alongside characterisations of Charles Babbage and Noor Inayat Khan. In 2021, Nvidia named its GPU architecture featured in the RTX 4000 Series, "Ada Lovelace", after her. It is also the first Nvidia architecture to feature both a first and last name. Commemoration The computer language Ada, created on behalf of the United States Department of Defense, was named after Lovelace. The reference manual for the language was approved on 10 December 1980 and the Department of Defense Military Standard for the language, MIL-STD-1815, was given the number of the year of her birth. In 1981, the Association for Women in Computing inaugurated its Ada Lovelace Award. Since 1998, the British Computer Society (BCS) has awarded the Lovelace Medal, and in 2008 initiated an annual competition for women students. BCSWomen sponsors the Lovelace Colloquium, an annual conference for women undergraduates. Ada College is a further-education college in Tottenham Hale, London, focused on digital skills. Ada Lovelace Day is an annual event celebrated on the second Tuesday of October, which began in 2009. Its goal is to "... raise the profile of women in science, technology, engineering, and maths," and to "create new role models for girls and women" in these fields. Events have included Wikipedia edit-a-thons with the aim of improving the representation of women on Wikipedia in terms of articles and editors to reduce unintended gender bias on Wikipedia. The Ada Initiative was a non-profit organisation dedicated to increasing the involvement of women in the free culture and open source movements. The Engineering in Computer Science and Telecommunications College building in Zaragoza University is called the Ada Byron Building. The computer centre in the village of Porlock, near where Lovelace lived, is named after her. Ada Lovelace House is a council-owned building in Kirkby-in-Ashfield, Nottinghamshire, near where Lovelace spent her infancy. In 2012, a Google Doodle and blog post honoured her on her birthday. In 2013, Ada Developers Academy was founded and named after her. The mission of Ada Developers Academy is to diversify tech by providing women and gender diverse people the skills, experience, and community support to become professional software developers to change the face of tech. On 17 September 2013, the BBC Radio 4 biography programme Great Lives devoted an episode to Ada Lovelace; she was sponsored by TV presenter Konnie Huq. As of November 2015, all new British passports have included an illustration of Lovelace and Babbage. In 2017, a Google Doodle honoured her with other women on International Women's Day. On 2 February 2018, Satellogic, a high-resolution Earth observation imaging and analytics company, launched a ÑuSat type micro-satellite named in honour of Ada Lovelace. In March 2018, The New York Times published a belated obituary for Ada Lovelace. On 27 July 2018, Senator Ron Wyden submitted, in the United States Senate, the designation of 9 October 2018 as National Ada Lovelace Day: "To honor the life and contributions of Ada Lovelace as a leading woman in science and mathematics". The resolution (S.Res.592) was considered, and agreed to without amendment and with a preamble by unanimous consent. In November 2020 it was announced that Trinity College Dublin whose library had previously held forty busts, all of them of men, was commissioning four new busts of women, one of whom was to be Lovelace. In March 2022, a statue of Ada Lovelace was installed at the site of the former Ergon House in the City of Westminster, London, honoring its scientific history. The redevelopment was part of a complex with Imperial Chemical House. The statue was sculpted by Etienne and Mary Millner and based on the portrait by Margaret Sarah Carpenter. The sculpture was unveiled on International Women's Day, 2022. It stands on the 7th floor of Millbank Quarter overlooking the junction of Dean Bradley Street and Horseferry Road. In September 2022, Nvidia announced the Ada Lovelace graphics processing unit (GPU) microarchitecture. Bicentenary The bicentenary of Ada Lovelace's birth was celebrated with a number of events, including: The Ada Lovelace Bicentenary Lectures on Computability, Israel Institute for Advanced Studies, 20 December 2015 – 31 January 2016.

August Derleth

August William Derleth (February 24, 1909 – July 4, 1971) was an American writer and anthologist. Though best remembered as the first book publisher of the writings of H. P. Lovecraft, and for his own contributions to the Cthulhu Mythos and the cosmic horror genre, as well as his founding of the publisher Arkham House (which did much to bring supernatural fiction into print in hardcover in the US that had only been readily available in the UK), Derleth was a leading American regional writer of his day, as well as prolific in several other genres, including historical fiction, poetry, detective fiction, science fiction, and biography. A 1938 Guggenheim Fellow, Derleth considered his most serious work to be the ambitious Sac Prairie Saga, a series of fiction, historical fiction, poetry, and non-fiction naturalist works designed to memorialize life in the Wisconsin he knew. Derleth can also be considered a pioneering naturalist and conservationist in his writing. Life The son of William Julius Derleth and Rose Louise Volk, Derleth grew up in Sauk City, Wisconsin. He was educated in local parochial and public high school. Derleth wrote his first fiction at age 13. He was interested most in reading, and he made three trips to the library a week. He would save his money to buy books (his personal library exceeded 12,000 volumes later on in life). Some of his biggest influences were Ralph Waldo Emerson's essays, Walt Whitman, H. L. Mencken's The American Mercury, Samuel Johnson's The History of Rasselas, Prince of Abissinia, Alexandre Dumas, Edgar Allan Poe, Walter Scott, and Henry David Thoreau's Walden. Forty rejected stories and three years later, according to anthologist Jim Stephens, he sold his first story, "Bat's Belfry", to Weird Tales magazine. Derleth wrote throughout his four years at the University of Wisconsin, where he received a B.A. in 1930. During this time he also served briefly as associate editor of Minneapolis-based Fawcett Publications Mystic Magazine. Returning to Sauk City in the summer of 1931, Derleth worked in a local canning factory and collaborated with childhood friend Mark Schorer (later Chairman of the University of California, Berkeley English Department). They rented a cabin, writing Gothic and other horror stories and selling them to Weird Tales magazine. Derleth won a place on the O'Brien Roll of Honor for Five Alone, published in Place of Hawks, but was first found in Pagany magazine. As a result of his early work on the Sac Prairie Saga, Derleth was awarded the prestigious Guggenheim Fellowship; his sponsors were Helen C. White, Nobel Prize-winning novelist Sinclair Lewis and poet Edgar Lee Masters of Spoon River Anthology fame. In the mid-1930s, Derleth organized a Ranger's Club for young people, served as clerk and president of the local school board, served as a parole officer, organized a local men's club and a parent-teacher association. He also lectured in American regional literature at the University of Wisconsin and was a contributing editor of Outdoors Magazine. With longtime friend Donald Wandrei, Derleth founded Arkham House in 1939. Its initial objective was to publish the works of H. P. Lovecraft, with whom Derleth had corresponded since his teenage years. At the same time, he began teaching a course in American Regional Literature at the University of Wisconsin. In 1941, he became literary editor of The Capital Times newspaper in Madison, a post he held until his resignation in 1960. His hobbies included fencing, swimming, chess, philately and comic-strips (Derleth reportedly used the funding from his Guggenheim Fellowship to bind his comic book collection, most recently valued in the millions of dollars, rather than to travel abroad as the award intended.). Derleth's true avocation, however, was hiking the terrain of his native Wisconsin lands, and observing and recording nature with an expert eye. Derleth once wrote of his writing methods, "I write very swiftly, from 750,000 to a million words yearly, very little of it pulp material." In 1948, he was elected president of the Associated Fantasy Publishers at the 6th World Science Fiction Convention in Toronto. He was married April 6, 1953, to Sandra Evelyn Winters. They divorced six years later. Derleth retained custody of the couple's two children, April Rose and Walden William. April earned a Bachelor of Arts degree in English from the University of Wisconsin-Madison in 1977. She became majority stockholder, President, and CEO of Arkham House in 1994. She remained in that capacity until her death. She was known in the community as a naturalist and humanitarian. April died on March 21, 2011. In 1960, Derleth began editing and publishing a magazine called Hawk and Whippoorwill, dedicated to poems of man and nature. Derleth died of a heart attack on July 4, 1971, and is buried in St. Aloysius Cemetery in Sauk City. The U.S. 12 bridge over the Wisconsin River is named in his honor. Derleth was Roman Catholic. In Derleth's biography, Dorothy M. Grobe Litersky stated that Derleth was bisexual, and maintained long-term romantic relationships with both men and women. This assertion has not been verified, however; no names were given of these romantic partners (in the interest of privacy according to Litersky), and no evidence or acknowledgement of Derleth having a bisexual or homosexual orientation has ever been found in his personal correspondence or writings. Career Derleth wrote more than 150 short stories and more than 100 books during his lifetime. The Sac Prairie Saga Derleth wrote an expansive series of novels, short stories, journals, poems, and other works about Sac Prairie. Derleth intended this series to comprise up to 50 novels telling the projected life-story of the region from the 19th century onwards, with analogies to Balzac's Human Comedy and Proust's Remembrance of Things Past. This, and other early work by Derleth, made him a well-known figure among the regional literary figures of his time: early Pulitzer Prize winners Hamlin Garland and Zona Gale, as well as Sinclair Lewis, the last both an admirer and critic of Derleth. As Edward Wagenknecht wrote in Cavalcade of the American Novel, "What Mr. Derleth has that is lacking...in modern novelists generally, is a country. He belongs. He writes of a land and a people that are bone of his bone and flesh of his flesh. In his fictional world, there is a unity much deeper and more fundamental than anything that can be conferred by an ideology. It is clear, too, that he did not get the best, and most fictionally useful, part of his background material from research in the library; like Scott, in his Border novels, he gives, rather, the impression of having drunk it in with his mother's milk." Jim Stephens, editor of An August Derleth Reader, (1992), argues: "what Derleth accomplished....was to gather a Wisconsin mythos which gave respect to the ancient fundament of our contemporary life." The author inaugurated the Sac Prairie Saga with four novellas comprising Place of Hawks, published by Loring & Mussey in 1935. At publication, The Detroit News wrote: "Certainly with this book Mr. Derleth may be added to the American writers of distinction." Derleth's first novel, Still is the Summer Night, was published two years later by the famous Charles Scribners' editor Maxwell Perkins, and was the second in his Sac Prairie Saga. Village Year, the first in a series of journals – meditations on nature, Midwestern village American life, and more – was published in 1941 to praise from The New York Times Book Review: "A book of instant sensitive responsiveness...recreates its scene with acuteness and beauty, and makes an unusual contribution to the Americana of the present day." The New York Herald Tribune observed that "Derleth...deepens the value of his village setting by presenting in full the enduring natural background; with the people projected against this, the writing comes to have the quality of an old Flemish picture, humanity lively and amusing and loveable in the foreground and nature magnificent beyond." James Grey, writing in the St. Louis Dispatch concluded, "Derleth has achieved a kind of prose equivalent of the Spoon River Anthology." In the same year, Evening in Spring was published by Charles Scribners & Sons. This work Derleth considered among his finest. What The Milwaukee Journal called "this beautiful little love story", is an autobiographical novel of first love beset by small-town religious bigotry. The work received critical praise: The New Yorker considered it a story told "with tenderness and charm", while the Chicago Tribune concluded: "It's as though he turned back the pages of an old diary and told, with rekindled emotion, of the pangs of pain and the sharp, clear sweetness of a boy's first love." Helen Constance White, wrote in The Capital Times that it was "...the best articulated, the most fully disciplined of his stories." These were followed in 1943 with Shadow of Night, a Scribners' novel of which The Chicago Sun wrote: "Structurally it has the perfection of a carved jewel...A psychological novel of the first order, and an adventure tale that is unique and inspiriting." In November 1945, however, Derleth's work was attacked by his one-time admirer and mentor, Sinclair Lewis. Writing in Esquire, Lewis observed, "It is a proof of Mr. Derleth's merit that he makes one want to make the journey and see his particular Avalon: The Wisconsin River shining among its islands, and the castles of Baron Pierneau and Hercules Dousman. He is a champion and a justification of regionalism. Yet he is also a burly, bounding, bustling, self-confident, opinionated, and highly-sweatered young man with faults so grievous that a melancholy perusal of them may be of more value to apprentices than a study of his serious virtues. If he could ever be persuaded that he isn't half as good as he thinks he is, if he would learn the art of sitting still and using a blue pencil, he might become twice as good as he thinks he is – which would about rank him with Homer." Derleth good-humoredly reprinted the criticism along with a photograph of himself sans sweater, on the back cover of his 1948 country journal: Village Daybook. A lighter side to the Sac Prairie Saga is a series of quasi-autobiographical short stories known as the "Gus Elker Stories", amusing tales of country life that Peter Ruber, Derleth's last editor, said were "...models of construction and...fused with some of the most memorable characters in American literature." Most were written between 1934 and the late 1940s, though the last, "Tail of the Dog", was published in 1959 and won the Scholastic Magazine short story award for the year. The series was collected and republished in Country Matters in 1996. Walden West, published in 1961, is considered by many Derleth's finest work. This prose meditation is built out of the same fundamental material as the series of Sac Prairie journals, but is organized around three themes: "the persistence of memory...the sounds and odors of the country...and Thoreau's observation that the 'mass of men lead lives of quiet desperation.'" A blend of nature writing, philosophic musings, and careful observation of the people and place of "Sac Prairie." Of this work, George Vukelich, author of "North Country Notebook", writes: "Derleth's Walden West is...the equal of Sherwood Anderson's Winesburg,Ohio, Thornton Wilder's Our Town, and Edgar Lee Masters' Spoon River Anthology." This was followed eight years later by Return to Walden West, a work of similar quality, but with a more noticeable environmentalist edge to the writing, notes critic Norbert Blei. A close literary relative of the Sac Prairie Saga was Derleth's Wisconsin Saga, which comprises several historical novels. Detective and mystery fiction Detective fiction represented another substantial body of Derleth's work. Most notable among this work was a series of 70 stories in affectionate pastiche of Sherlock Holmes, whose creator, Sir Arthur Conan Doyle, he admired greatly. The stories feature a Holmes-styled British detective named Solar Pons, of 7B Praed Street in London. These included one published novel as well (Mr. Fairlie's Final Journey). The series was greatly admired by such notable writers and critics of mystery and detective fiction as Ellery Queen (Frederic Dannay), Anthony Boucher, Vincent Starrett, and Howard Haycraft. In his 1944 volume The Misadventures of Sherlock Holmes, Ellery Queen wrote of Derleth's The Norcross Riddle, an early Pons story: "How many budding authors, not even old enough to vote, could have captured the spirit and atmosphere with as much fidelity?" Queen adds, "...and his choice of the euphonic Solar Pons is an appealing addition to the fascinating lore of Sherlockian nomenclature." Vincent Starrett, in his foreword to the 1964 edition of The Casebook of Solar Pons, wrote that the series is "...as sparkling a galaxy of Sherlockian pastiches as we have had since the canonical entertainments came to an end." Despite close similarities to Doyle's creation, Pons lived in the post-World War I era, in the decades of the 1920s and 1930s. Though Derleth never wrote a Pons novel to equal The Hound of the Baskervilles, editor Peter Ruber wrote: "...Derleth produced more than a few Solar Pons stories almost as good as Sir Arthur's, and many that had better plot construction." Although these stories were a form of diversion for Derleth, Ruber, who edited The Original Text Solar Pons Omnibus Edition (2000), argued: "Because the stories were generally of such high quality, they ought to be assessed on their own merits as a unique contribution in the annals of mystery fiction, rather than suffering comparison as one of the endless imitators of Sherlock Holmes." Some of the stories were self-published, through a new imprint called "Mycroft & Moran", an appellation of humorous significance to Holmesian scholars. For approximately a decade, an active supporting group was the Praed Street Irregulars, patterned after the Baker Street Irregulars. In 1946, Conan Doyle's two sons made some attempts to force Derleth to cease publishing the Solar Pons series, but the efforts were unsuccessful, and were eventually withdrawn. Derleth's mystery and detective fiction also included a series of works set in Sac Prairie and featuring Judge Peck as the central character. Youth and children's fiction Derleth wrote many and varied children's works, including biographies meant to introduce younger readers to explorer Jacques Marquette, as well as Ralph Waldo Emerson and Henry David Thoreau. Arguably most important among his works for younger readers, however, is the Steve and Sim Mystery Series, also known as the Mill Creek Irregulars series. The ten-volume series, published between 1958 and 1970, is set in Sac Prairie of the 1920s and can thus be considered in its own right a part of the Sac Prairie Saga, as well as an extension of Derleth's body of mystery fiction. Robert Hood, writing in the New York Times said: "Steve and Sim, the major characters, are twentieth-century cousins of Huck Finn and Tom Sawyer; Derleth's minor characters, little gems of comic drawing." The first novel in the series, The Moon Tenders, does, in fact, involve a rafting adventure down the Wisconsin River, which led regional writer Jesse Stuart to suggest the novel was one that "older people might read to recapture the spirit and dream of youth." The connection to the Sac Prairie Saga was noted by the Chicago Tribune: "Once again a small midwest community in 1920s is depicted with perception, skill, and dry humor." Arkham House and the "Cthulhu Mythos" Derleth was a correspondent and friend of H. P. Lovecraft – when Lovecraft wrote about "le Comte d'Erlette" in his fiction, it was in homage to Derleth. Derleth invented the term "Cthulhu Mythos" to describe the fictional universe depicted in the series of stories shared by Lovecraft and other writers in his circle. When Lovecraft died in 1937, Derleth and Donald Wandrei assembled a collection of Lovecraft's stories and tried to get them published. Existing publishers showed little interest, so Derleth and Wandrei founded Arkham House in 1939 for that purpose. The name of the company derived from Lovecraft's fictional town of Arkham, Massachusetts, which features in many of his stories. In 1939, Arkham House published The Outsider and Others, a huge collection that contained most of Lovecraft's known short stories. Derleth and Wandrei soon expanded Arkham House and began a regular publishing schedule after its second book, Someone in the Dark, a collection of some of Derleth's own horror stories, was published in 1941. Following Lovecraft's death, Derleth wrote a number of stories based on fragments and notes left by Lovecraft. These were published in Weird Tales and later in book form, under the byline "H. P. Lovecraft and August Derleth", with Derleth calling himself a "posthumous collaborator." This practice has raised objections in some quarters that Derleth simply used Lovecraft's name to market what was essentially his own fiction; S. T. Joshi refers to the "posthumous collaborations" as marking the beginning of "perhaps the most disreputable phase of Derleth's activities". Dirk W. Mosig, S. T. Joshi, and Richard L. Tierney were dissatisfied with Derleth's invention of the term Cthulhu Mythos (Lovecraft himself used Yog-Sothothery) and his presentation of Lovecraft's fiction as having an overall pattern reflecting Derleth's own Christian world view, which they contrast with Lovecraft's depiction of an amoral universe. However, Robert M. Price points out that while Derleth's tales are distinct from Lovecraft's in their use of hope and his depiction of a struggle between good and evil, nevertheless the basis of Derlerth's systemization are found in Lovecraft. He also suggests that the differences can be overstated: Derleth was more optimistic than Lovecraft in his conception of the Mythos, but we are dealing with a difference more of degree than kind. There are indeed tales wherein Derleth's protagonists get off scot-free (like "The Shadow in the Attic", "Witches' Hollow", or "The Shuttered Room"), but often the hero is doomed (e.g., "The House in the Valley", "The Peabody Heritage", "Something in Wood"), as in Lovecraft. And it must be remembered that an occasional Lovecraftian hero does manage to overcome the odds, e.g., in "The Horror in the Museum", "The Shunned House", and 'The Case of Charles Dexter Ward'. Derleth also treated Lovecraft's Great Old Ones as representatives of elemental forces, creating new fictional entities to flesh out this framework. Such debates aside, Derleth's founding of Arkham House and his successful effort to rescue Lovecraft from literary oblivion are widely acknowledged by practitioners in the horror field as seminal events in the field. For instance, Ramsey Campbell has acknowledged Derleth's encouragement and guidance during the early part of his own writing career, and Kirby McCauley has cited Derleth and Arkham House as an inspiration for his own anthology Dark Forces. Arkham House and Derleth published Dark Carnival, the first book by Ray Bradbury, as well. Brian Lumley cites the importance of Derleth to his own Lovecraftian work, and contends in a 2009 introduction to Derleth's work that he was "...one of the first, finest, and most discerning editors and publishers of macabre fiction." Important as was Derleth's work to rescue H.P. Lovecraft from literary obscurity at the time of Lovecraft's death, Derleth also built a body of horror and spectral fiction of his own; still frequently anthologized. The best of this work, recently reprinted in four volumes of short stories – most of which were originally published in Weird Tales, illustrates Derleth's original abilities in the genre. While Derleth considered his work in this genre less important than his most serious literary efforts, the compilers of these four anthologies, including Ramsey Campbell, note that the stories still resonate after more than 50 years. In 2009, The Library of America selected Derleth's story The Panelled Room for inclusion in its two-century retrospective of American Fantastic Tales. Other works Derleth also wrote many historical novels, as part of both the Sac Prairie Saga and the Wisconsin Saga. He also wrote history; arguably most notable among these was The Wisconsin: River of a Thousand Isles, published in 1942. The work was one in a series entitled "The Rivers of America", conceived by writer Constance Lindsay Skinner in the Great Depression as a series that would connect Americans to their heritage through the history of the great rivers of the nation. Skinner wanted the series to be written by artists, not academicians. Derleth, while not a trained historian, was, according to former Wisconsin state historian William F. Thompson, "...a very competent regional historian who based his historical writing upon research in the primary documents and who regularly sought the help of professionals... ." In the foreword to the 1985 reissue of the work by The University of Wisconsin Press, Thompson concluded: "No other writer, of whatever background or training, knew and understood his particular 'corner of the earth' better than August Derleth." Additionally, Derleth wrote a number of volumes of poetry. Three of his collections – Rind of Earth (1942), Selected Poems (1944), and The Edge of Night (1945) – were published by the Decker Press, which also printed the work of other Midwestern poets such as Edgar Lee Masters. Derleth was also the author of several biographies of other writers, including Zona Gale, Ralph Waldo Emerson and Henry David Thoreau. He also wrote introductions to several collections of classic early 20th century comics, such as Buster Brown, Little Nemo in Slumberland, and Katzenjammer Kids, as well as a book of children's poetry entitled A Boy's Way, and the foreword to Tales from an Indian Lodge by Phebe Jewell Nichols. Derleth also wrote under the pen names Stephen Grendon, Kenyon Holmes and Tally Mason. Derleth's papers were donated to the Wisconsin Historical Society in Madison.

Alps

The Alps () are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation levels vary greatly and climatic conditions consist of distinct zones. Wildlife such as ibex live in the higher peaks to elevations of , and plants such as edelweiss grow in rocky areas in lower elevations as well as in higher elevations. Evidence of human habitation in the Alps goes back to the Palaeolithic era. A mummified man, determined to be 5,000 years old, was discovered on a glacier at the Austrian–Italian border in 1991. By the 6th century BC, the Celtic La Tène culture was well established. Hannibal notably crossed the Alps with a herd of elephants, and the Romans had settlements in the region. In 1800, Napoleon crossed one of the mountain passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, and artists, in particular, the Romantics, followed by the golden age of alpinism as mountaineers began to ascend the peaks. The Alpine region has a strong cultural identity. The traditional culture of farming, cheesemaking, and woodworking still exists in Alpine villages, although the tourist industry began to grow early in the 20th century and expanded greatly after World War II to become the dominant industry by the end of the century. The Winter Olympic Games have been hosted in the Swiss, French, Italian, Austrian and German Alps. the region is home to 14 million people and has 120 million annual visitors. Etymology and toponymy The English word Alps comes from the Latin Alpes. The Latin word Alpes could possibly come from the adjective albus ("white"), or could possibly come from the Greek goddess Alphito, whose name is related to alphita, the "white flour"; alphos, a dull white leprosy; and finally the Proto-Indo-European word *albʰós. Similarly, the river god Alpheus is also supposed to derive from the Greek alphos and means whitish. In his commentary on the Aeneid of Vergil, the late fourth-century grammarian Maurus Servius Honoratus says that all high mountains are called Alpes by Celts. According to the Oxford English Dictionary, the Latin Alpes might derive from a pre-Indo-European word *alb "hill"; "Albania" is a related derivation. Albania, a name not native to the region known as the country of Albania, has been used as a name for several mountainous areas across Europe. In Roman times, "Albania" was a name for the eastern Caucasus, while in the English languages "Albania" (or "Albany") was occasionally used as a name for Scotland, although it is more likely derived from the Latin word albus, the color white. In modern languages the term alp, alm, albe or alpe refers to a grazing pastures in the alpine regions below the glaciers, not the peaks. An alp refers to a high mountain pasture, typically near or above the tree line, where cows and other livestock are taken to be grazed during the summer months and where huts and hay barns can be found, sometimes constituting tiny hamlets. Therefore, the term "the Alps", as a reference to the mountains, is a misnomer. The term for the mountain peaks varies by nation and language: words such as Horn, Kogel, Kopf, Gipfel, Spitze, Stock, and Berg are used in German-speaking regions; Mont, Pic, Tête, Pointe, Dent, Roche, and Aiguille in French-speaking regions; and Monte, Picco, Corno, Punta, Pizzo, or Cima in Italian-speaking regions. Geography The Alps are a crescent shaped geographic feature of central Europe that ranges in an arc (curved line) from east to west and is in width. The mean height of the mountain peaks is . The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble, and stretching eastward through mid and southern Switzerland. The range continues onward toward Vienna, Austria, and east to the Adriatic Sea and Slovenia. To the south it dips into northern Italy and to the north extends to the southern border of Bavaria in Germany. In areas like Chiasso, Switzerland, and Allgäu, Bavaria, the demarcation between the mountain range and the flatlands are clear; in other places such as Geneva, the demarcation is less clear. The countries with the greatest alpine territory are Austria (28.7% of the total area), Italy (27.2%), France (21.4%) and Switzerland (13.2%). The highest portion of the range is divided by the glacial trough of the Rhône valley, from Mont Blanc to the Matterhorn and Monte Rosa on the southern side, and the Bernese Alps on the northern. The peaks in the easterly portion of the range, in Austria and Slovenia, are smaller than those in the central and western portions. The variances in nomenclature in the region spanned by the Alps make classification of the mountains and subregions difficult, but a general classification is that of the Eastern Alps and Western Alps with the divide between the two occurring in eastern Switzerland according to geologist Stefan Schmid, near the Splügen Pass. The highest peaks of the Western Alps and Eastern Alps, respectively, are Mont Blanc, at , and Piz Bernina, at . The second-highest major peaks are Monte Rosa, at , and Ortler, at , respectively. A series of lower mountain ranges run parallel to the main chain of the Alps, including the French Prealps in France and the Jura Mountains in Switzerland and France. The secondary chain of the Alps follows the watershed from the Mediterranean Sea to the Wienerwald, passing over many of the highest and most well-known peaks in the Alps. From the Colle di Cadibona to Col de Tende it runs westwards, before turning to the northwest and then, near the Colle della Maddalena, to the north. Upon reaching the Swiss border, the line of the main chain heads approximately east-northeast, a heading it follows until its end near Vienna. The northeast end of the Alpine arc, directly on the Danube, which flows into the Black Sea, is the Leopoldsberg near Vienna. In contrast, the southeastern part of the Alps ends on the Adriatic Sea in the area around Trieste towards Duino and Barcola. Passes The Alps have been crossed for war and commerce, and by pilgrims, students and tourists. Crossing routes by road, train, or foot are known as passes, and usually consist of depressions in the mountains in which a valley leads from the plains and hilly pre-mountainous zones. In the medieval period hospices were established by religious orders at the summits of many of the main passes. The most important passes are the Col de l'Iseran (the highest), the Col Agnel, the Brenner Pass, the Mont-Cenis, the Great St. Bernard Pass, the Col de Tende, the Gotthard Pass, the Semmering Pass, the Simplon Pass, and the Stelvio Pass. Crossing the Italian-Austrian border, the Brenner Pass separates the Ötztal Alps and Zillertal Alps and has been in use as a trading route since the 14th century. The lowest of the Alpine passes at , the Semmering crosses from Lower Austria to Styria; since the 12th century when a hospice was built there, it has seen continuous use. A railroad with a tunnel long was built along the route of the pass in the mid-19th century. With a summit of , the Great St Bernard Pass is one of the highest in the Alps, crossing the Italian-Swiss border east of the Pennine Alps along the flanks of Mont Blanc. The pass was used by Napoleon Bonaparte to cross 40,000 troops in 1800. The Mont Cenis pass has been a major commercial and military road between Western Europe and Italy. The pass was crossed by many troops on their way to the Italian peninsula. From Constantine I, Pepin the Short and Charlemagne to Henry IV, Napoléon and more recently the German Gebirgsjägers during World War II. Now the pass has been supplanted by the Fréjus Highway Tunnel (opened 1980) and Rail Tunnel (opened 1871). The Saint Gotthard Pass crosses from Central Switzerland to Ticino; in 1882 the Saint Gotthard Railway Tunnel was opened connecting Lucerne in Switzerland, with Milan in Italy. 98 years later followed Gotthard Road Tunnel ( long) connecting the A2 motorway in Göschenen on the north side with Airolo on the south side, exactly like the railway tunnel. On 1 June 2016 the world's longest railway tunnel, the Gotthard Base Tunnel, was opened, which connects Erstfeld in canton of Uri with Bodio in canton of Ticino by two single tubes of . It is the first tunnel that traverses the Alps on a flat route. From 11 December 2016, it has been part of the regular railway timetable and used hourly as standard ride between Basel/Lucerne/Zurich and Bellinzona/Lugano/Milan. The highest pass in the alps is the Col de l'Iseran in Savoy (France) at , followed by the Stelvio Pass in northern Italy at ; the road was built in the 1820s. Highest mountains The Union Internationale des Associations d'Alpinisme (UIAA) has defined a list of 82 "official" Alpine summits that reach at least . The list includes not only mountains, but also subpeaks with little prominence that are considered important mountaineering objectives. Below are listed the 29 "four-thousanders" with at least of prominence. While Mont Blanc was first climbed in 1786 and the Jungfrau in 1811, most of the Alpine four-thousanders were climbed during the second half of the 19th century, notably Piz Bernina (1850), the Dom (1858), the Grand Combin (1859), the Weisshorn (1861) and the Barre des Écrins (1864); the ascent of the Matterhorn in 1865 marked the end of the golden age of alpinism. Karl Blodig (1859–1956) was among the first to successfully climb all the major 4,000 m peaks. He completed his series of ascents in 1911. Many of the big Alpine three-thousanders were climbed in the early 19th century, notably the Grossglockner (1800) and the Ortler (1804), although some of them were climbed only much later, such at Mont Pelvoux (1848), Monte Viso (1861) and La Meije (1877). The first British Mont Blanc ascent by a man was in 1788; the first ascent by a woman was in 1808. By the mid-1850s Swiss mountaineers had ascended most of the peaks and were eagerly sought as mountain guides. Edward Whymper reached the top of the Matterhorn in 1865 (after seven attempts), and in 1938 the last of the six great north faces of the Alps was climbed with the first ascent of the Eiger Nordwand (north face of the Eiger). Geology and orogeny Important geological concepts were established as naturalists began studying the rock formations of the Alps in the 18th century. In the mid-19th century, the now-defunct theory of geosynclines was used to explain the presence of "folded" mountain chains but by the mid-20th century the theory of plate tectonics became widely accepted. The formation of the Alps (the Alpine orogeny) was an episodic process that began about 300 million years ago. In the Paleozoic Era the Pangaean supercontinent consisted of a single tectonic plate; it broke into separate plates during the Mesozoic Era and the Tethys sea developed between Laurasia and Gondwana during the Jurassic Period. The Tethys was later squeezed between colliding plates causing the formation of mountain ranges called the Alpide belt, from Gibraltar through the Himalayas to Indonesia—a process that began at the end of the Mesozoic and continues into the present. The formation of the Alps was a segment of this orogenic process, caused by the collision between the African and the Eurasian plates that began in the late Cretaceous Period. Under extreme compressive stresses and pressure, marine sedimentary rocks were uplifted, creating characteristic recumbent folds, or nappes, and thrust faults. As the rising peaks underwent erosion, a layer of marine flysch sediments was deposited in the foreland basin, and the sediments became involved in younger nappes (folds) as the orogeny progressed. Coarse sediments from the continual uplift and erosion were later deposited in foreland areas as molasse. The molasse regions in Switzerland and Bavaria were well-developed and saw further upthrusting of flysch. The Alpine orogeny occurred in ongoing cycles through to the Paleogene causing differences in nappe structures, with a late-stage orogeny causing the development of the Jura Mountains. A series of tectonic events in the Triassic, Jurassic and Cretaceous periods caused different paleogeographic regions. The Alps are subdivided by different lithology (rock composition) and nappe structures according to the orogenic events that affected them. The geological subdivision differentiates the Western, Eastern Alps, and Southern Alps: the Helveticum in the north, the Penninicum and Austroalpine system in the centre and, south of the Periadriatic Seam, the Southern Alpine system. According to geologist Stefan Schmid, because the Western Alps underwent a metamorphic event in the Cenozoic Era while the Austroalpine peaks underwent an event in the Cretaceous Period, the two areas show distinct differences in nappe formations. Flysch deposits in the Southern Alps of Lombardy probably occurred in the Cretaceous or later. Peaks in France, Italy and Switzerland lie in the "Houillière zone", which consists of basement with sediments from the Mesozoic Era. High "massifs" with external sedimentary cover are more common in the Western Alps and were affected by Neogene Period thin-skinned thrusting whereas the Eastern Alps have comparatively few high peaked massifs. Similarly the peaks in eastern Switzerland extending to western Austria (Helvetic nappes) consist of thin-skinned sedimentary folding that detached from former basement rock. In simple terms, the structure of the Alps consists of layers of rock of European, African, and oceanic (Tethyan) origin. The bottom nappe structure is of continental European origin, above which are stacked marine sediment nappes, topped off by nappes derived from the African plate. The Matterhorn is an example of the ongoing orogeny and shows evidence of great folding. The tip of the mountain consists of gneisses from the African plate; the base of the peak, below the glaciated area, consists of European basement rock. The sequence of Tethyan marine sediments and their oceanic basement is sandwiched between rock derived from the African and European plates. The core regions of the Alpine orogenic belt have been folded and fractured in such a manner that erosion created the characteristic steep vertical peaks of the Swiss Alps that rise seemingly straight out of the foreland areas. Peaks such as Mont Blanc, the Matterhorn, and high peaks in the Pennine Alps, the Briançonnais, and Hohe Tauern consist of layers of rock from the various orogenies including exposures of basement rock. Due to the ever-present geologic instability, earthquakes continue in the Alps to this day. Typically, the largest earthquakes in the alps have been between magnitude 6 and 7 on the Richter scale. Geodetic measurements show ongoing topographic uplift at rates of up to about 2.5 mm/a in the North, Western and Central Alps, and at ~1 mm/a in the Eastern and South-Western Alps. The underlying mechanisms that jointly drive the present-day uplift pattern are the isostatic rebound due to the melting of the last glacial maximum ice-cap or long-term erosion, detachment of the Western Alpine subducting slab, mantle convection as well as ongoing horizontal convergence between Africa and Europe, but their relative contributions to the uplift of the Alps are difficult to quantify and likely to vary significantly in space and time. Minerals The Alps are a source of minerals that have been mined for thousands of years. In the 8th to 6th centuries, BC during the Hallstatt culture, Celtic tribes mined copper; later the Romans mined gold for coins in the Bad Gastein area. Erzberg in Styria furnishes high-quality iron ore for the steel industry. Crystals, such as cinnabar, amethyst, and quartz, are found throughout much of the Alpine region. The cinnabar deposits in Slovenia are a notable source of cinnabar pigments. Alpine crystals have been studied and collected for hundreds of years and began to be classified in the 18th century. Leonhard Euler studied the shapes of crystals, and by the 19th-century crystal hunting was common in Alpine regions. David Friedrich Wiser amassed a collection of 8000 crystals that he studied and documented. In the 20th century Robert Parker wrote a well-known work about the rock crystals of the Swiss Alps; at the same period a commission was established to control and standardize the naming of Alpine minerals. Glaciers In the Miocene Epoch the mountains underwent severe erosion because of glaciation, which was noted in the mid-19th century by naturalist Louis Agassiz who presented a paper proclaiming the Alps were covered in ice at various intervals—a theory he formed when studying rocks near his Neuchâtel home which he believed originated to the west in the Bernese Oberland. Because of his work he came to be known as the "father of the ice-age concept" although other naturalists before him put forth similar ideas. Agassiz studied glacier movement in the 1840s at the Unteraar Glacier where he found the glacier moved per year, more rapidly in the middle than at the edges. His work was continued by other scientists and now a permanent laboratory exists inside a glacier under the Jungfraujoch, devoted exclusively to the study of Alpine glaciers. Glaciers pick up rocks and sediment with them as they flow. This causes erosion and the formation of valleys over time. The Inn valley is an example of a valley carved by glaciers during the ice ages with a typical terraced structure caused by erosion. Eroded rocks from the most recent ice age lie at the bottom of the valley while the top of the valley consists of erosion from earlier ice ages. Glacial valleys have characteristically steep walls (reliefs); valleys with lower reliefs and talus slopes are remnants of glacial troughs or previously infilled valleys. Moraines, piles of rock picked up during the movement of the glacier, accumulate at edges, centre, and the terminus of glaciers. Alpine glaciers can be straight rivers of ice, long sweeping rivers, spread in a fan-like shape (Piedmont glaciers), and curtains of ice that hang from vertical slopes of the mountain peaks. The stress of the movement causes the ice to break and crack loudly, perhaps explaining why the mountains were believed to be home to dragons in the medieval period. The cracking creates unpredictable and dangerous crevasses, often invisible under new snowfall, which causes the greatest danger to mountaineers. Glaciers end in ice caves (the Rhône Glacier), by trailing into a lake or river, or by shedding snowmelt on a meadow. Sometimes a piece of glacier will detach or break resulting in flooding, property damage, and loss of life. High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the level. The of the Alps covered by glaciers in 1876 had shrunk to by 1973, resulting in decreased river run-off levels. Forty percent of the glaciation in Austria has disappeared since 1850, and 30% of that in Switzerland. Although the Alpine topography shows marked glacial morphologies, the mechanisms by which glacial reshaping occurs are unclear. Numerical modeling suggests that glacial erosion propagates from low elevations to high elevations leading to an early increase of local relief followed by lowering of the mean orogen elevation. Rivers and lakes The Alps provide lowland Europe with drinking water, irrigation, and hydroelectric power. Although the area is only about 11% of the surface area of Europe, the Alps provide up to 90% of water to lowland Europe, particularly to arid areas and during the summer months. Cities such as Milan depend on 80% of water from Alpine runoff. Water from the rivers is used in at least 550 hydroelectricity power plants, considering only those producing at least 10MW of electricity. Major European rivers flow from the Alps, such as the Rhine, the Rhône, the Inn, and the Po, all of which have headwaters in the Alps and flow into neighbouring countries, finally emptying into the North Sea, the Mediterranean Sea, the Adriatic Sea and the Black Sea. Other rivers such as the Danube have major tributaries flowing into them that originate in the Alps. The Rhône is second to the Nile as a freshwater source to the Mediterranean Sea; the river begins as glacial meltwater, flows into Lake Geneva, and from there to France where one of its uses is to cool nuclear power plants. The Rhine originates in a area in Switzerland and represents almost 60% of water exported from the country. Tributary valleys, some of which are complicated, channel water to the main valleys which can experience flooding during the snowmelt season when rapid runoff causes debris torrents and swollen rivers. The rivers form lakes, such as Lake Geneva, a crescent-shaped lake crossing the Swiss border with Lausanne on the Swiss side and the town of Evian-les-Bains on the French side. In Germany, the medieval St. Bartholomew's chapel was built on the south side of the Königssee, accessible only by boat or by climbing over the abutting peaks. Additionally, the Alps have led to the creation of large lakes in Italy. For instance, the Sarca, the primary inflow of Lake Garda, originates in the Italian Alps. The Italian Lakes are a popular tourist destination since the Roman Era for their mild climate. Scientists have been studying the impact of climate change and water use. For example, each year more water is diverted from rivers for snowmaking in the ski resorts, the effect of which is yet unknown. Furthermore, the decrease of glaciated areas combined with a succession of winters with lower-than-expected precipitation may have a future impact on the rivers in the Alps as well as an effect on the water availability to the lowlands. Climate The Alps are a classic example of what happens when a temperate area at lower altitude gives way to higher-elevation terrain. Elevations around the world that have cold climates similar to those of the polar regions have been called Alpine. A rise from sea level into the upper regions of the atmosphere causes the temperature to decrease (see adiabatic lapse rate). The effect of mountain chains on prevailing winds is to carry warm air belonging to the lower region into an upper zone, where it expands in volume at the cost of a proportionate loss of temperature, often accompanied by precipitation in the form of snow or rain. The height of the Alps is sufficient to divide the weather patterns in Europe into a wet north and dry south because moisture is sucked from the air as it flows over the high peaks. The severe weather in the Alps has been studied since the 18th century; particularly the weather patterns such as the seasonal foehn wind. Numerous weather stations were placed in the mountains early in the early 20th century, providing continuous data for climatologists. Some of the valleys are quite arid such as the Aosta valley in Italy, the Maurienne in France, the Valais in Switzerland, and northern Tyrol. The areas that are not arid and receive high precipitation experience periodic flooding from rapid snowmelt and runoff. The mean precipitation in the Alps ranges from a low of per year to per year, with the higher levels occurring at high altitudes. At altitudes between , snowfall begins in November and accumulates through to April or May when the melt begins. Snow lines vary from , above which the snow is permanent and the temperatures hover around the freezing point even during July and August. High-water levels in streams and rivers peak in June and July when the snow is still melting at the higher altitudes. The Alps are split into five climatic zones, each with different vegetation. The climate, plant life, and animal life vary among the different sections or zones of the mountains. The lowest zone is the colline zone, which exists between , depending on the location. The montane zone extends from , followed by the sub-Alpine zone from . The Alpine zone, extending from tree line to the snow line, is followed by the glacial zone, which covers the glaciated areas of the mountain. Climatic conditions show variances within the same zones; for example, weather conditions at the head of a mountain valley, extending directly from the peaks, are colder and more severe than those at the mouth of a valley which tend to be less severe and receive less snowfall. Various models of climate change have been projected into the 22nd century for the Alps, with an expectation that a trend toward increased temperatures will have an effect on snowfall, snowpack, glaciation, and river runoff. Significant changes, of both natural and anthropogenic origins, have already been diagnosed from observations. Ecology Flora Thirteen thousand species of plants have been identified in the Alpine regions. Alpine plants are grouped by habitat and soil type which can be limestone or non-calcareous. The habitats range from meadows, bogs, and woodland (deciduous and coniferous) areas to soil-less scree and moraines, and rock faces and ridges. A natural vegetation limit with altitude is given by the presence of the chief deciduous trees—oak, beech, ash and sycamore maple. These do not reach the same elevation, nor are they often found growing together, but their upper limit corresponds accurately enough to the change from a temperate to a colder climate that is further proved by a change in the presence of wild herbaceous vegetation. This limit usually lies about above the sea on the north side of the Alps, but on the southern slopes it often rises to , sometimes even to . Above the forestry, there is often a band of short pine trees (Pinus mugo), which is in turn superseded by Alpenrosen, dwarf shrubs, typically Rhododendron ferrugineum (on acid soils) or Rhododendron hirsutum (on alkaline soils). Although Alpenrose prefers acidic soil, the plants are found throughout the region. Above the tree line is the area defined as "alpine" where in the alpine meadow plants are found that have adapted well to harsh conditions of cold temperatures, aridity, and high altitudes. The alpine area fluctuates greatly because of regional fluctuations in tree lines. Alpine plants such as the Alpine gentian grow in abundance in areas such as the meadows above the Lauterbrunnental. Gentians are named after the Illyrian king Gentius, and 40 species of the early-spring blooming flower grow in the Alps, in a range of . Writing about the gentians in Switzerland D. H. Lawrence described them as "darkening the day-time, torch-like with the smoking blueness of Pluto's gloom." Gentians tend to "appear" repeatedly as the spring blooming takes place at progressively later dates, moving from the lower altitude to the higher altitude meadows where the snow melts much later than in the valleys. On the highest rocky ledges, the spring flowers bloom in the summer. At these higher altitudes, the plants tend to form isolated cushions. In the Alps, several species of flowering plants have been recorded above , including Ranunculus glacialis, Androsace alpina and Saxifraga biflora. Eritrichium nanum, commonly known as the King of the Alps, is the most elusive of the alpine flowers, growing on rocky ridges at . Perhaps the best known of the alpine plants is Edelweiss which grows in rocky areas and can be found at altitudes as low as and as high as . The plants that grow at the highest altitudes have adapted to conditions by specialization such as growing in rock screes that give protection from winds. The extreme and stressful climatic conditions give way to the growth of plant species with secondary metabolites important for medicinal purposes. Origanum vulgare, Prunella vulgaris, Solanum nigrum, and Urtica dioica are some of the more useful medicinal species found in the Alps. Human interference has nearly exterminated the trees in many areas, and, except for the beech forests of the Austrian Alps, forests of deciduous trees are rarely found after the extreme deforestation between the 17th and 19th centuries. The vegetation has changed since the second half of the 20th century, as the high alpine meadows cease to be harvested for hay or used for grazing which eventually might result in a regrowth of the forest. In some areas, the modern practice of building ski runs by mechanical means has destroyed the underlying tundra from which the plant life cannot recover during the non-skiing months, whereas areas that still practice a natural piste type of ski slope building preserve the fragile underlayers. Fauna The Alps are a habitat for 30,000 species of wildlife, ranging from the tiniest snow fleas to brown bears, many of which have made adaptations to the harsh cold conditions and high altitudes to the point that some only survive in specific micro-climates either directly above or below the snow line. The largest mammal to live in the highest altitudes are the alpine ibex, which have been sighted as high as . The ibex live in caves and descend to eat the succulent alpine grasses. Classified as antelopes, chamois are smaller than ibex and found throughout the Alps, living above the tree line and are common in the entire alpine range. Areas of the eastern Alps are still home to brown bears. In Switzerland the canton of Bern was named for the bears but the last bear is recorded as having been killed in 1792 above Kleine Scheidegg by three hunters from Grindelwald. Many rodents such as voles live underground. Marmots live almost exclusively above the tree line as high as . They hibernate in large groups to provide warmth, and can be found in all areas of the Alps, in large colonies they build beneath the alpine pastures. Golden eagles and bearded vultures are the largest birds to be found in the Alps; they nest high on rocky ledges and can be found at altitudes of . The most common bird is the alpine chough which can be found scavenging at climber's huts or the Jungfraujoch, a high-altitude tourist destination. Reptiles such as adders and vipers live up to the snow line; because they cannot bear the cold temperatures they hibernate underground and soak up the warmth on rocky ledges. The high-altitude Alpine salamanders have adapted to living above the snow line by giving birth to fully developed young rather than laying eggs. Brown trout can be found in the streams up to the snow line. Molluscs such as the wood snail live up the snow line. Popularly gathered as food, the snails are now protected. Several species of moths live in the Alps, some of which are believed to have evolved in the same habitat up to 120 million years ago, long before the Alps were created. Blue butterflies can commonly be seen drinking from the snowmelt; some species of blues fly as high as . The butterflies tend to be large, such as those from the swallowtail Parnassius family, with a habitat that ranges to . Twelve species of beetles have habitats up to the snow line; the most beautiful and formerly collected for its colours but now protected is Rosalia alpina. Spiders, such as the large wolf spider, live above the snow line and can be seen as high as . Scorpions can be found in the Italian Alps. Some of the species of moths and insects show evidence of having been indigenous to the area from as long ago as the Alpine orogeny. In Émosson in Valais, Switzerland, dinosaur tracks were found in the 1970s, dating probably from the Triassic Period. History Prehistory to Christianity About 10,000 years ago, when the ice melted after the Würm glaciation, late Palaeolithic communities were established along the lake shores and in cave systems. Evidence of human habitation has been found in caves near Vercors, close to Grenoble and Echirolles; in Austria, the Mondsee culture shows evidence of houses built on piles to keep them dry. Standing stones have been found in the Alpine areas of France and Italy. The Rock Drawings in Valcamonica are more than 5000 years old; more than 200,000 drawings and etchings have been identified at the site. In 1991, a mummy of a neolithic body, known as Ötzi the Iceman, was discovered by hikers on the Similaun glacier. His clothing and gear indicate that he lived in an alpine farming community, while the location and manner of his death – an arrowhead was discovered in his shoulder – suggests he was travelling from one place to another. Analysis of the mitochondrial DNA of Ötzi, has shown that he belongs to the K1 subclade which cannot be categorized into any of the three modern branches of that subclade. The new subclade has provisionally been named K1ö for Ötzi. Celtic tribes settled in Switzerland between 1500 and 1000 BC. The Raetians lived in the eastern regions, while the west was occupied by the Helvetii and the Allobrogi settled in the Rhône valley and in Savoy. The Ligurians and Adriatic Veneti lived in north-west Italy and Triveneto respectively. Among the many substances Celtic tribes mined was salt in areas such as Salzburg in Austria where evidence of the Hallstatt culture was found by a mine manager in the 19th century. By the 6th century BC the La Tène culture was well established in the region, and became known for high quality decorated weapons and jewellery. The Celts were the most widespread of the mountain tribes—they had warriors that were strong, tall and fair-skinned, and skilled with iron weapons, which gave them an advantage in warfare. During the Second Punic War in 218 BC, the Carthaginian general Hannibal probably crossed the Alps with an army numbering 38,000 infantry, 8,000 cavalry, and 37 war elephants. This was one of the most celebrated achievements of any military force in ancient warfare, although no evidence exists of the actual crossing or the place of crossing. The Romans, however, had built roads along the mountain passes, which continued to be used through the medieval period to cross the mountains and Roman road markers can still be found on the mountain passes. The Roman expansion brought the defeat of the Allobrogi in 121 BC and during the Gallic Wars in 58 BC Julius Caesar overcame the Helvetii. The Rhaetians continued to resist but were eventually conquered when the Romans turned northward to the Danube valley in Austria and defeated the Brigantes. The Romans built settlements in the Alps; towns such as Aosta (named for Augustus) in Italy, Martigny and Lausanne in Switzerland, and Partenkirchen in Bavaria show remains of Roman baths, villas, arenas, and temples. Much of the Alpine region was gradually settled by Germanic tribes, (Lombards, Alemanni, Bavarii, and Franks) from the 6th to the 13th centuries mixing with the local Celtic tribes. Christianity, feudalism, and Napoleonic wars Christianity was established in the region by the Romans and saw the establishment of monasteries and churches in the high regions. The Frankish expansion of the Carolingian Empire and the Bavarian expansion in the eastern Alps introduced feudalism and the building of castles to support the growing number of dukedoms and kingdoms. Castello del Buonconsiglio in Trento, Italy, still has intricate frescoes, excellent examples of Gothic art, in a tower room. In Switzerland, Château de Chillon is preserved as an example of medieval architecture. There are several important alpine saints and one such one is Saint Maurice who gives his name to the town St. Moritz. Much of the medieval period was a time of power struggles between competing dynasties such as the House of Savoy, the Visconti in northern Italy, and the House of Habsburg in Austria and Slovenia. In 1291, to protect themselves from incursions by the Habsburgs, four cantons in the middle of Switzerland drew up a charter that is considered to be a declaration of independence from neighbouring kingdoms. After a series of battles fought in the 13th, 14th, and 15th centuries, more cantons joined the confederacy and by the 16th century, Switzerland was well-established as a separate state. During the Napoleonic Wars in the late 18th century and early 19th century, Napoleon annexed territory formerly controlled by the Habsburgs and Savoys. In 1798, he established the Helvetic Republic in Switzerland; two years later he led an army across the St. Bernard pass and conquered almost all of the Alpine regions. After the fall of Napoléon, many alpine countries developed heavy protections to prevent any new invasion. Thus, Savoy built a series of fortifications in the Maurienne valley to protect the major alpine passes, such as the col du Mont-Cenis that was even crossed by Charlemagne and his father to defeat the Lombards. The latter indeed became very popular after the construction of a paved road ordered by Napoléon Bonaparte. The Barrière de l'Esseillon is a series of forts with heavy batteries, built on a cliff with a perfect view of the valley, a gorge on one side, and steep mountains on the other side. In the 19th century, the monasteries built in the high Alps during the medieval period to shelter travellers and as places of pilgrimage became tourist destinations. The Benedictines had built monasteries in Lucerne, Switzerland, and Oberammergau; the Cistercians in the Tyrol and at Lake Constance, and the Augustinians had abbeys in the Savoy and one in the centre of Interlaken, Switzerland. The Great St Bernard Hospice, built in the 9th or 10th centuries, at the summit of the Great Saint Bernard Pass was a shelter for travellers and place for pilgrims since its inception; by the 19th century it became a tourist attraction with notable visitors such as author Charles Dickens and mountaineer Edward Whymper. Exploration Radiocarbon-dated charcoal placed around 50,000 years ago was found in the Drachloch (Dragon's Hole) cave above the village of Vattis in the canton of St. Gallen, proving that the high peaks were visited by prehistoric people. Seven bear skulls from the cave may have been buried by the same prehistoric people. The peaks, however, were mostly ignored except for a few notable examples, and long left to the exclusive attention of the people of the adjoining valleys. The mountain peaks were seen as terrifying, the abode of dragons and demons, to the point that people blindfolded themselves to cross the Alpine passes. The glaciers remained a mystery and many still believed the highest areas to be inhabited by dragons. Charles VII of France ordered his chamberlain to climb Mont Aiguille in 1356. The knight reached the summit of Rocciamelone where he left a bronze triptych of three crosses, a feat which he conducted with the use of ladders to traverse the ice. In 1492, Antoine de Ville climbed Mont Aiguille, without reaching the summit, an experience he described as "horrifying and terrifying." Leonardo da Vinci was fascinated by variations of light in the higher altitudes, and climbed a mountain—scholars are uncertain which one; some believe it may have been Monte Rosa. From his description of a "blue like that of a gentian" sky it is thought that he reached a significantly high altitude. In the 18th century four Chamonix men almost made the summit of Mont Blanc but were overcome by altitude sickness and snowblindness. Conrad Gessner was the first naturalist to ascend the mountains in the 16th century, to study them, writing that in the mountains he found the "theatre of the Lord". By the 19th century more naturalists began to arrive to explore, study and conquer the high peaks. Two men who first explored the regions of ice and snow were Horace-Bénédict de Saussure (1740–1799) in the Pennine Alps, and the Benedictine monk of Disentis Placidus a Spescha (1752–1833). Born in Geneva, Saussure was enamoured with the mountains from an early age; he left a law career to become a naturalist and spent many years trekking through the Bernese Oberland, the Savoy, the Piedmont and Valais, studying the glaciers and geology, as he became an early proponent of the theory of rock upheaval. Saussure, in 1787, was a member of the third ascent of Mont Blanc—today the summits of all the peaks have been climbed. The Romantics and Alpinists Albrecht von Haller's poem Die Alpen (1732) described the mountains as an area of mythical purity. Jean-Jacques Rousseau was another writer who presented the Alps as a place of allure and beauty, in his novel Julie, or the New Heloise (1761), Later the first wave of Romantics such as Goethe and Turner came to admire the scenery; Wordsworth visited the area in 1790, writing of his experiences in The Prelude (1799). Schiller later wrote the play William Tell (1804), which tells the story of the legendary Swiss marksman William Tell as part of the greater Swiss struggle for independence from the Habsburg Empire in the early 14th century. At the end of the Napoleonic Wars, the Alpine countries began to see an influx of poets, artists, and musicians, as visitors came to experience the sublime effects of monumental nature. In 1816, Byron, Percy Bysshe Shelley and his wife Mary Shelley visited Geneva and all three were inspired by the scenery in their writings. During these visits Shelley wrote the poem "Mont Blanc", Byron wrote "The Prisoner of Chillon" and the dramatic poem Manfred, and Mary Shelley, who found the scenery overwhelming, conceived the idea for the novel Frankenstein in her villa on the shores of Lake Geneva amid a thunderstorm. When Coleridge travelled to Chamonix, he declaimed, in defiance of Shelley, who had signed himself "Atheos" in the guestbook of the Hotel de Londres near Montenvers, "Who would be, who could be an atheist in this valley of wonders". By the mid-19th century scientists began to arrive en masse to study the geology and ecology of the region. From the beginning of the 19th century, the tourism and mountaineering development of the Alps began. In the early years of the "golden age of alpinism" initially scientific activities were mixed with sport, for example by the physicist John Tyndall, with the first ascent of the Matterhorn by Edward Whymper being the highlight. In the later years, the "silver age of alpinism", the focus was on mountain sports and climbing. The first president of the Alpine Club, John Ball, is considered the discoverer of the Dolomites, which for decades were the focus of climbers like Paul Grohmann, Michael Innerkofler and Angelo Dibona. The Nazis Austrian-born Adolf Hitler had a lifelong romantic fascination with the Alps and by the 1930s established a home at Berghof, in the Obersalzberg region outside of Berchtesgaden. His first visit to the area was in 1923 and he maintained a strong tie there until the end of his life. At the end of World War II, the US Army occupied Obersalzberg, to prevent Hitler from retreating with the Wehrmacht into the mountains. By 1940 many of the Alpine countries were under the control of the Axis powers. Austria underwent a political coup that made it part of the Third Reich; France had been invaded and Italy was a fascist regime. Switzerland and Liechtenstein were the only countries to avoid an Axis takeover. The Swiss Confederation mobilized its troops—the country follows the doctrine of "armed neutrality" with all males required to have military training—a number that General Eisenhower estimated to be about 850,000. The Swiss commanders wired the infrastructure leading into the country with explosives, and threatened to destroy bridges, railway tunnels, and roads across passes in the event of a Nazi invasion; and if there was an invasion the Swiss army would then have retreated to the heart of the mountain peaks, where conditions were harsher, and a military invasion would involve difficult and protracted battles. German Ski troops were trained for the war, and battles were waged in mountainous areas such as the battle at Riva Ridge in Italy, where the American 10th Mountain Division encountered heavy resistance in February 1945. At the end of the war, a substantial amount of Nazi plunder was found stored in Austria, where Hitler had hoped to retreat as the war drew to a close. The salt mines surrounding the Altaussee area, where American troops found of gold coins stored in a single mine, were used to store looted art, jewels, and currency; vast quantities of looted art were found and returned to the owners. Largest cities The largest city within the Alps is the city of Grenoble in France. Other larger and important cities within the Alps with over 100,000 inhabitants are in Tyrol with Bolzano (Italy), Trento (Italy) and Innsbruck (Austria). Larger cities outside the Alps are Milan, Verona, Turin (Italy), Munich (Germany), Graz, Vienna, Salzburg (Austria), Ljubljana, Maribor, Kranj (Slovenia), Zurich, Geneva (Switzerland), Nice and Lyon (France). Cities with over 100,000 inhabitants in the Alps are: Alpine people and culture The population of the region is 14 million spread across eight countries. On the rim of the mountains, on the plateaus, and on the plains the economy consists of manufacturing and service jobs whereas in the higher altitudes and the mountains farming is still essential to the economy. Farming and forestry continue to be mainstays of Alpine culture, industries that provide for export to the cities and maintain the mountain ecology. The Alpine regions are multicultural and linguistically diverse. Dialects are common and vary from valley to valley and region to region. In the Slavic Alps alone 19 dialects have been identified. Some of the Romance dialects spoken in the French, Swiss and Italian alps of Aosta Valley derive from Arpitan, while the southern part of the western range is related to Occitan; the German dialects derive from Germanic tribal languages. Romansh, spoken by two percent of the population in southeast Switzerland, is an ancient Rhaeto-Romanic language derived from Latin, remnants of ancient Celtic languages and perhaps Etruscan. Much of the Alpine culture is unchanged since the medieval period when skills that guaranteed survival in the mountain valleys and the highest villages became mainstays, leading to strong traditions of carpentry, woodcarving, baking, pastry-making, and cheesemaking. Farming has been a traditional occupation for centuries, although it became less dominant in the 20th century with the advent of tourism. Grazing and pasture land are limited because of the steep and rocky topography of the Alps. In mid-June, cows are moved to the highest pastures close to the snowline, where they are watched by herdsmen who stay in the high altitudes often living in stone huts or wooden barns during the summers. Villagers celebrate the day the cows are herded up to the pastures and again when they return in mid-September. The Almabtrieb, Alpabzug, Alpabfahrt, Désalpes ("coming down from the alps") is celebrated by decorating the cows with garlands and enormous cowbells while the farmers dress in traditional costumes. Cheesemaking is an ancient tradition in most Alpine countries. A wheel of cheese from the Emmental in Switzerland can weigh up to , and the Beaufort in Savoy can weigh up to . Owners of the cows traditionally receive from the cheesemakers a portion about the proportion of the cows' milk from the summer months in the high alps. Haymaking is an important farming activity in mountain villages that have become somewhat mechanized in recent years, although the slopes are so steep that scythes are usually necessary to cut the grass. Hay is normally brought in twice a year, often also on festival days. In the high villages, people live in homes built according to medieval designs that withstand cold winters. The kitchen is separated from the living area (called the stube, the area of the home heated by a stove), and second-floor bedrooms benefit from rising heat. The typical Swiss chalet originated in the Bernese Oberland. Chalets often face south or downhill and are built of solid wood, with a steeply gabled roof to allow accumulated snow to slide off easily. Stairs leading to upper levels are sometimes built on the outside, and balconies are sometimes enclosed. Food is passed from the kitchen to the stube, where the dining room table is placed. Some meals are communal, such as fondue, where a pot is set in the middle of the table for each person to dip into. Other meals are still served traditionally on carved wooden plates. Furniture has been traditionally elaborately carved and in many Alpine countries, carpentry skills are passed from generation to generation. Roofs are traditionally constructed from Alpine rocks such as pieces of schist, gneiss, or slate. Such chalets are typically found in the higher parts of the valleys, as in the Maurienne valley in Savoy, where the amount of snow during the cold months is important. The inclination of the roof cannot exceed 40%, allowing the snow to stay on top, thereby functioning as insulation from the cold. In the lower areas where the forests are widespread, wooden tiles are traditionally used. Commonly made of Norway spruce, they are called "tavaillon". In the German-speaking parts of the Alps (Austria, Bavaria, South Tyrol, Liechtenstein and Switzerland), there is a strong tradition of Alpine folk culture. Old traditions are carefully maintained among inhabitants of Alpine areas, even though this is seldom obvious to the visitor: many people are members of cultural associations where the Alpine folk culture is cultivated. At cultural events, traditional folk costume (in German Tracht) is expected: typically lederhosen for men and dirndls for women. Visitors can get a glimpse of the rich customs of the Alps at public Volksfeste. Even when large events feature only a little folk culture, all participants take part with gusto. Good opportunities to see local people celebrating the traditional culture occur at the many fairs, wine festivals, and firefighting festivals which fill weekends in the countryside from spring to autumn. Alpine festivals vary from country to country. Frequently they include music (e.g. the playing of Alpenhorns), dance (e.g. Schuhplattler), sports (e.g. wrestling marches and archery), as well as traditions with pagan roots such as the lighting of fires on Walpurgis Night and Saint John's Eve. Many areas celebrate Fastnacht in the weeks before Lent. Folk costume also continues to be worn for most weddings and festivals. Tourism The Alps are one of the more popular tourist destinations in the world with many resorts such as Oberstdorf, in Bavaria, Saalbach in Austria, Davos in Switzerland, Chamonix in France, and Cortina d'Ampezzo in Italy recording more than a million annual visitors. With over 120 million visitors a year, tourism is integral to the Alpine economy with much of it coming from winter sports, although summer visitors are also an important component. The tourism industry began in the early 19th century when foreigners visited the Alps, travelled to the bases of the mountains to enjoy the scenery, and stayed at the spa-resorts. Large hotels were built during the Belle Époque; cog-railways, built early in the 20th century, brought tourists to ever-higher elevations, with the Jungfraubahn terminating at the Jungfraujoch, well above the eternal snow-line, after going through a tunnel in Eiger. During this period winter sports were slowly introduced: in 1882 the first figure skating championship was held in St. Moritz, and downhill skiing became a popular sport with English visitors early in the 20th century, as the first ski-lift was installed in 1908 above Grindelwald. In the first half of the 20th century the Olympic Winter Games were held three times in Alpine venues: the 1924 Winter Olympics in Chamonix, France; the 1928 Winter Olympics in St. Moritz, Switzerland; and the 1936 Winter Olympics in Garmisch-Partenkirchen, Germany. During World War II the winter games were cancelled but after that time the Winter Games have been held in St. Moritz (1948), Cortina d'Ampezzo (1956), Innsbruck, Austria (1964 and 1976), Grenoble, France, (1968), Albertville, France, (1992), and Torino (2006). In 1930, the Lauberhorn Rennen (Lauberhorn Race), was run for the first time on the Lauberhorn above Wengen; the equally demanding Hahnenkamm was first run in the same year in Kitzbühl, Austria. Both races continue to be held each January on successive weekends. The Lauberhorn is the more strenuous downhill race at and poses danger to racers who reach within seconds of leaving the start gate. During the post-World War I period, ski lifts were built in Swiss and Austrian towns to accommodate winter visitors, but summer tourism continued to be important; by the mid-20th century the popularity of downhill skiing increased greatly as it became more accessible and in the 1970s several new villages were built in France devoted almost exclusively to skiing, such as Les Menuires. Until this point, Austria and Switzerland had been the traditional and more popular destinations for winter sports, but by the end of the 20th century and into the early 21st century, France, Italy, and the Tyrol began to see increases in winter visitors. From 1980 to the present, ski-lifts have been modernized and snow-making machines installed at many resorts, leading to mounting concerns regarding the loss of traditional Alpine culture and uncertainties regarding sustainable development. For instance the number of ski resorts and piste kilometres has declined since 2015, a likely result of climatic change. Avalanche/snow-slide 17th-century French-Italian border avalanche: in the 17th century about 2500 people were killed by an avalanche in a village on the French-Italian border. 19th century Zermatt avalanche: in the 19th century, 120 homes in a village near Zermatt were destroyed by an avalanche.

Train travel is well established in the Alps, with, for instance of track for every in a country such as Switzerland. Most of Europe's highest railways are located there. In 2007, the new Lötschberg Base Tunnel was opened, which circumvents the 100 years older Lötschberg Tunnel. With the opening of the Gotthard Base Tunnel on June 1, 2016, it bypasses the Gotthard Tunnel built in the 19th century and realizes the first flat route through the Alps. Some high mountain villages are car-free either because of inaccessibility or by choice. Wengen, and Zermatt (in Switzerland) are accessible only by cable car or cog-rail trains. Avoriaz (in France), is car-free, with other Alpine villages considering becoming car-free zones or limiting the number of cars for reasons of sustainability of the fragile Alpine terrain. The lower regions and larger towns of the Alps are well-served by motorways and main roads, but higher mountain passes and byroads, which are amongst the highest in Europe, can be treacherous even in summer due to steep slopes. Many passes are closed in winter. Several airports around the Alps (and some within), as well as long-distance rail links from all neighbouring countries, afford large numbers of travellers easy access.

Albert Camus

Albert Camus ( , ; ; 7 November 1913 – 4 January 1960) was a French philosopher, author, dramatist, and journalist. He was the recipient of the 1957 Nobel Prize in Literature at the age of 44, the second-youngest recipient in history. His works include The Stranger, The Plague, The Myth of Sisyphus, The Fall, and The Rebel. Camus was born in French Algeria to Pieds Noirs parents. He spent his childhood in a poor neighbourhood and later studied philosophy at the University of Algiers. He was in Paris when the Germans invaded France during World War II in 1940. Camus tried to flee but finally joined the French Resistance where he served as editor-in-chief at Combat, an outlawed newspaper. After the war, he was a celebrity figure and gave many lectures around the world. He married twice but had many extramarital affairs. Camus was politically active; he was part of the left that opposed Joseph Stalin and the Soviet Union because of their totalitarianism. Camus was a moralist and leaned towards anarcho-syndicalism. He was part of many organisations seeking European integration. During the Algerian War (1954–1962), he kept a neutral stance, advocating for a multicultural and pluralistic Algeria, a position that caused controversy and was rejected by most parties. Philosophically, Camus's views contributed to the rise of the philosophy known as absurdism. Some consider Camus's work to show him to be an existentialist, even though he himself firmly rejected the term throughout his lifetime. Life Early years and education Albert Camus was born on 7 November 1913 in a working-class neighborhood in Mondovi (present-day Dréan), in French Algeria. His mother, Catherine Hélène Camus (née Sintès), was French with Balearic Spanish ancestry. He never knew his father, Lucien Camus, a poor French agricultural worker killed in action while serving with Zouaves, in October 1914, during World War I. Camus, his mother and other relatives lived without many basic material possessions during his childhood in the Belcourt section of Algiers. Camus was a second-generation French inhabitant of Algeria, a French territory from 1830 until 1962. His paternal grandfather, along with many others of his generation, had moved to Algeria for a better life during the first decades of the 19th century. Hence, he was called —a slang term for French people born in Algeria. His identity and poor background had a substantial effect on his later life. Nevertheless, Camus was a French citizen and enjoyed more rights than Arab and Berber Algerians under indigénat. During his childhood, he developed a love for football and swimming. Under the influence of his teacher Louis Germain, Camus gained a scholarship in 1924 to continue his studies at a prestigious lyceum (secondary school) near Algiers. In 1930, at the age of 17, he was diagnosed with tuberculosis. Because it is a transmitted disease, he moved out of his home and stayed with his uncle Gustave Acault, a butcher, who influenced the young Camus. It was at that time he turned to philosophy, with the mentoring of his philosophy teacher Jean Grenier. He was impressed by ancient Greek philosophers and Friedrich Nietzsche. During that time, he was only able to study part-time. To earn money, he took odd jobs: as a private tutor, car parts clerk, and assistant at the Meteorological Institute. In 1933, Camus enrolled at the University of Algiers and completed his licence de philosophie (BA) in 1936; after presenting his thesis on Plotinus. Camus developed an interest in early Christian philosophers, but Nietzsche and Arthur Schopenhauer had paved the way towards pessimism and atheism. Camus also studied novelist-philosophers such as Stendhal, Herman Melville, Fyodor Dostoyevsky, and Franz Kafka. In 1933, he also met Simone Hié, then a partner of a friend of Camus, who would become his first wife. Camus played goalkeeper for the Racing Universitaire d'Alger junior team from 1928 to 1930. The sense of team spirit, fraternity, and common purpose appealed to him enormously. In match reports, he was often praised for playing with passion and courage. Any football ambitions, however, disappeared when he contracted tuberculosis. Camus drew parallels among football, human existence, morality, and personal identity. For him, the simplistic morality of football contradicted the complicated morality imposed by authorities such as the state and Church. Formative years In 1934, aged 20, Camus was in a relationship with Simone Hié. Simone had an addiction to morphine, a drug she used to ease her menstrual pains. His uncle Gustave did not approve of the relationship, but Camus married Hié to help her fight her addiction. He subsequently discovered she was in a relationship with her doctor at the same time and the couple later divorced. Camus joined the French Communist Party (PCF) in early 1935. He saw it as a way to "fight inequalities between Europeans and 'natives' in Algeria," even though he was not a Marxist. He explained: "We might see communism as a springboard and asceticism that prepares the ground for more spiritual activities." Camus left the PCF a year later. In 1936, the independence-minded Algerian Communist Party (PCA) was founded, and Camus joined it after his mentor Grenier advised him to do so. Camus's main role within the PCA was to organise the Théâtre du Travail ("Workers' Theatre"). Camus was also close to the Parti du Peuple Algérien (Algerian People's Party (PPA)), which was a moderate anti-colonialist/nationalist party. As tensions in the interwar period escalated, the Stalinist PCA and PPA broke ties. Camus was expelled from the PCA for refusing to toe the party line. This series of events sharpened his belief in human dignity. Camus's mistrust of bureaucracies that aimed for efficiency instead of justice grew. He continued his involvement with theatre and renamed his group Théâtre de l'Equipe ("Theatre of the Team"). Some of his scripts were the basis for his later novels. In 1938, Camus began working for the leftist newspaper Alger républicain (founded by Pascal Pia) as he had strong anti-fascist feelings, and the rise of fascist regimes in Europe was worrying him. By then, Camus had developed strong feelings against authoritative colonialism as he witnessed the harsh treatment of the Arabs and Berbers by French authorities. Alger républicain was banned in 1940 and Camus flew to Paris to take a new job at Paris-Soir as editor-in-chief. In Paris, he almost completed his "first cycle" of works dealing with the absurd and the meaningless—the novel L'Étranger (The Outsider (UK), or The Stranger (US)), the philosophical essay Le Mythe de Sisyphe (The Myth of Sisyphus) and the play Caligula. Each cycle consisted of a novel, an essay and a theatrical play. World War II, Resistance and Combat Soon after Camus moved to Paris, the outbreak of World War II began to affect France. Camus volunteered to join the army but was not accepted because he once had tuberculosis. As the Germans were marching towards Paris, Camus fled. He was laid off from Paris-Soir and ended up in Lyon, where he married pianist and mathematician Francine Faure on 3 December 1940. Camus and Faure moved back to Algeria (Oran) where he taught in primary schools. Because of his tuberculosis, he moved to the French Alps on medical advice. There he began writing his second cycle of works, this time dealing with revolt—a novel La Peste (The Plague) and a play Le Malentendu (The Misunderstanding). By 1943 he was known because of his earlier work. He returned to Paris where he met and became friends with Jean-Paul Sartre. He also became part of a circle of intellectuals including Simone de Beauvoir, André Breton, and others. Among them was the actress María Casares, who would later have an affair with Camus. Camus took an active role in the underground resistance movement against the Germans during the French Occupation. Upon his arrival in Paris, he started working as a journalist and editor of the banned newspaper Combat. He continued writing for the paper after the liberation of France. Camus used a pseudonym for his Combat articles and used false ID cards to avoid being captured. During that period he composed four Lettres à un Ami Allemand (Letters to a German Friend), explaining why resistance was necessary. Post–World War II After the War, Camus lived in Paris with Faure, who gave birth to twins, Catherine and Jean, in 1945. Camus was now a celebrated writer known for his role in the Resistance. He gave lectures at various universities in the United States and Latin America during two separate trips. He also visited Algeria once more, only to leave disappointed by the continued oppressive colonial policies, which he had warned about many times. During this period he completed the second cycle of his work, with the essay L'Homme révolté (The Rebel). Camus attacked totalitarian communism while advocating libertarian socialism and anarcho-syndicalism. Upsetting many of his colleagues and contemporaries in France with his rejection of communism, the book brought about the final split with Sartre. His relations with the Marxist Left deteriorated further during the Algerian War. Camus was a strong supporter of European integration in various marginal organisations working towards that end. In 1944, he founded the Comité français pour la féderation européenne—(CFFE (French Committee for the European Federation))—declaring that Europe "can only evolve along the path of economic progress, democracy, and peace if the nation-states become a federation." In 1947–48, he founded the Groupes de Liaison Internationale (GLI) a trade union movement in the context of revolutionary syndicalism (syndicalisme révolutionnaire). His main aim was to express the positive side of surrealism and existentialism, rejecting the negativity and the nihilism of André Breton. Camus also raised his voice against the Soviet intervention in Hungary and the totalitarian tendencies of Franco's regime in Spain. Camus had numerous affairs, particularly an irregular and eventually public affair with the Spanish-born actress María Casares, with whom he had extensive correspondence. Faure did not take this affair lightly. She had a mental breakdown and needed hospitalisation in the early 1950s. Camus, who felt guilty, withdrew from public life and was slightly depressed for some time. In 1957, Camus received the news that he was to be awarded the Nobel Prize in Literature. This came as a shock to him. He was anticipating André Malraux would win the prestigious award. At age 44, he was the second-youngest recipient of the prize, after Rudyard Kipling, who was 42. After this he began working on his autobiography Le Premier Homme (The First Man) in an attempt to examine "moral learning". He also turned to the theatre once more. Financed by the money he received with his Nobel Prize, he adapted and directed for the stage Dostoyevsky's novel Demons. The play opened in January 1959 at the Antoine Theatre in Paris and was a critical success. During these years, he published posthumously the works of the philosopher Simone Weil, in the series "Espoir" ("Hope") which he had founded for Éditions Gallimard. Weil had great influence on his philosophy, since he saw her writings as an "antidote" to nihilism. Camus described her as "the only great spirit of our times". Death Camus died on 4 January 1960 at the age of 46, in a car accident near Sens, in Le Grand Fossard in the small town of Villeblevin. He had spent the New Year's holiday of 1960 at his house in Lourmarin, Vaucluse with his family, and his publisher Michel Gallimard of Éditions Gallimard, along with Gallimard's wife, Janine, and daughter. Camus's wife and children went back to Paris by train on 2 January, but Camus decided to return in Gallimard's luxurious Facel Vega FV2. The car crashed into a plane tree on a long straight stretch of the Route nationale 5 (now the RN 6 or D606). Camus, who was in the passenger seat, died instantly. Gallimard died a few days later, although his wife and daughter were unharmed. 144 pages of a handwritten manuscript entitled Le premier Homme (The First Man) were found in the wreckage. Camus had predicted that this unfinished novel based on his childhood in Algeria would be his finest work. Camus was buried in the Lourmarin Cemetery, Vaucluse, France, where he had lived. His friend Sartre read a eulogy, paying tribute to Camus's heroic "stubborn humanism". William Faulkner wrote his obituary, saying, "When the door shut for him he had already written on this side of it that which every artist who also carries through life with him that one same foreknowledge and hatred of death, is hoping to do: I was here." Literary career Camus's first publication was a play called Révolte dans les Asturies (Revolt in the Asturias) written with three friends in May 1936. The subject was the 1934 revolt by Spanish miners that was brutally suppressed by the Spanish government resulting in 1,500 to 2,000 deaths. In May 1937 he wrote his first book, L'Envers et l'Endroit (Betwixt and Between, also translated as The Wrong Side and the Right Side). Both were published by Edmond Charlot's small publishing house. Camus separated his work into three cycles. Each cycle consisted of a novel, an essay, and a play. The first was the cycle of the absurd consisting of L'Étranger, Le Mythe de Sysiphe, and Caligula. The second was the cycle of the revolt which included La Peste (The Plague), L'Homme révolté (The Rebel), and Les Justes (The Just Assassins). The third, the cycle of the love, consisted of Nemesis. Each cycle was an examination of a theme with the use of a pagan myth and including biblical motifs. The books in the first cycle were published between 1942 and 1944, but the theme was conceived earlier, at least as far back as 1936. With this cycle, Camus aims to pose a question on the human condition, discuss the world as an absurd place, and warn humanity of the consequences of totalitarianism. Camus began his work on the second cycle while he was in Algeria, in the last months of 1942, just as the Germans were reaching North Africa. In the second cycle, Camus used Prometheus, who is depicted as a revolutionary humanist, to highlight the nuances between revolution and rebellion. He analyses various aspects of rebellion, its metaphysics, its connection to politics, and examines it under the lens of modernity, of historicity and the absence of a God. After receiving the Nobel Prize, Camus gathered, clarified, and published his pacifist leaning views at Actuelles III: Chronique algérienne 1939–1958 (Algerian Chronicles). He then decided to distance himself from the Algerian War as he found the mental burden too heavy. He turned to theatre and the third cycle which was about love and the goddess Nemesis. Two of Camus's works were published posthumously. The first entitled La mort heureuse (A Happy Death) (1970), features a character named Patrice Mersault, comparable to The Strangers Meursault. There is scholarly debate about the relationship between the two books. The second was an unfinished novel, Le Premier homme (The First Man) (1995), which Camus was writing before he died. It was an autobiographical work about his childhood in Algeria and its publication in 1994 sparked a widespread reconsideration of Camus's allegedly unrepentant colonialism. Political stance Camus was a moralist; he claimed morality should guide politics. While he did not deny that morals change over time, he rejected the classical Marxist view that historical material relations define morality. Camus was also strongly critical of Marxism-Leninism, especially in the case of the Soviet Union, which he considered totalitarian. Camus rebuked those sympathetic to the Soviet model and their "decision to call total servitude freedom". A proponent of libertarian socialism, he claimed the USSR was not socialist, and the United States was not liberal. His critique of the USSR caused him to clash with others on the political left, most notably with his on-again, off-again friend Jean-Paul Sartre. Active in the French Resistance to the Nazi occupation of France during World War II, Camus wrote for and edited the Resistance journal Combat. Of the French collaboration with the German occupiers, he wrote: "Now the only moral value is courage, which is useful here for judging the puppets and chatterboxes who pretend to speak in the name of the people." After France's liberation, Camus remarked, "This country does not need a Talleyrand, but a Saint-Just." The reality of the postwar tribunals soon changed his mind: Camus publicly reversed himself and became a lifelong opponent of capital punishment. Camus had anarchist sympathies, which intensified in the 1950s, when he came to believe that the Soviet model was morally bankrupt. Camus was firmly against any kind of exploitation, authority, property, the State, and centralization. He, however, opposed revolution, separating the rebel from the revolutionary and believing that the belief in "absolute truth", most often assuming the guise of history or reason, inspires the revolutionary and leads to tragic results. He believed that rebellion is spurred by our outrage over the world's lack of transcendent significance, while political rebellion is our response to attacks against the dignity and autonomy of the individual. Camus opposed political violence, tolerating it only in rare and very narrowly defined instances, as well as revolutionary terror which he accused of sacrificing innocent lives on the altar of history. Philosophy professor David Sherman considers Camus an anarcho-syndicalist. Graeme Nicholson considers Camus an existentialist anarchist. The anarchist André Prudhommeaux first introduced him at a meeting of the Cercle des Étudiants Anarchistes ("Anarchist Student Circle") in 1948 as a sympathiser familiar with anarchist thought. Camus wrote for anarchist publications such as Le Libertaire (The Libertarian), La Révolution prolétarienne (The Proletarian Revolution), and Solidaridad Obrera ("Workers' Solidarity"), the organ of the anarcho-syndicalist Confederación Nacional del Trabajo (CNT) ("National Confederation of Labor"). Camus kept a neutral stance during the Algerian Revolution (1954–62). While he was against the violence of the National Liberation Front (FLN) he acknowledged the injustice and brutalities imposed by colonialist France. He was supportive of Pierre Mendès' Unified Socialist Party (PSU) and its approach to the crisis; Mendes advocated reconciliation. Camus also supported a like-minded Algerian militant, Aziz Kessous. Camus traveled to Algeria to negotiate a truce between the two belligerents but was met with distrust by all parties. In one, often misquoted incident, Camus confronted an Algerian critic during his 1957 Nobel Prize acceptance speech in Stockholm, rejecting the false equivalence of justice with revolutionary terrorism: "People are now planting bombs in the tramways of Algiers. My mother might be on one of those tramways. If that is justice, then I prefer my mother." Camus's critics have labelled the response as reactionary and a result of a colonialist attitude. He was sharply critical of the proliferation of nuclear weapons and the bombings of Hiroshima and Nagasaki. In the 1950s, Camus devoted his efforts to human rights. In 1952, he resigned from his work for UNESCO when the UN accepted Spain, under the leadership of the caudillo General Francisco Franco, as a member. Camus maintained his pacifism and resisted capital punishment anywhere in the world. He wrote an essay against capital punishment in collaboration with Arthur Koestler, the writer, intellectual, and founder of the League Against Capital Punishment entitled Réflexions sur la peine capitale (Reflections on capital punishment), published by Calmann-Levy in 1957. Role in Algeria Born in Algeria to French parents, Camus was familiar with the institutional racism of France against Arabs and Berbers, but he was not part of a rich elite. He lived in very poor conditions as a child but was a citizen of France and as such was entitled to citizens' rights; members of the country's Arab and Berber majority were not. Camus was a vocal advocate of the "new Mediterranean Culture". This was his vision of embracing the multi-ethnicity of the Algerian people, in opposition to "Latiny", a popular pro-fascist and antisemitic ideology among other Pieds-Noirs—or French or Europeans born in Algeria. For Camus, this vision encapsulated the Hellenic humanism which survived among ordinary people around the Mediterranean Sea. His 1938 address on "The New Mediterranean Culture" represents Camus's most systematic statement of his views at this time. Camus also supported the Blum–Viollette proposal to grant Algerians full French citizenship in a manifesto with arguments defending this assimilative proposal on radical egalitarian grounds. In 1939, Camus wrote a stinging series of articles for the Alger républicain on the atrocious living conditions of the inhabitants of the Kabylie highlands. He advocated for economic, educational and political reforms as a matter of emergency. In 1945, following the Sétif and Guelma massacre after Arab revolts against French mistreatment, Camus was one of only a few mainland journalists to visit the colony. He wrote a series of articles reporting on conditions, and advocating for French reforms and concessions to the demands of the Algerian people. When the Algerian War began in 1954, Camus was confronted with a moral dilemma. He identified with the Pieds-Noirs such as his own parents and defended the French government's actions against the revolt. He argued the Algerian uprising was an integral part of the "new Arab imperialism" led by Egypt, and an "anti-Western" offensive orchestrated by Russia to "encircle Europe" and "isolate the United States". Although favoring greater Algerian autonomy or even federation, though not full-scale independence, he believed the Pieds-Noirs and Arabs could co-exist. During the war, he advocated a civil truce that would spare the civilians. It was rejected by both sides who regarded it as foolish. Behind the scenes, he began working for imprisoned Algerians who faced the death penalty. His position drew much criticism from the left and later postcolonial literary critics, such as Edward Said, who were opposed to European imperialism, and charged that Camus's novels and short stories are plagued with colonial depictions - or conscious erasures - of Algeria's Arab population. In their eyes, Camus was no longer the defender of the oppressed. Camus once said that the troubles in Algeria "affected him as others feel pain in their lungs." Philosophy Existentialism Even though Camus is mostly connected to absurdism, he is routinely categorized as an existentialist, a term he rejected on several occasions. Camus himself said his philosophical origins lay in ancient Greek philosophy, Nietzsche, and 17th-century moralists whereas existentialism arises from 19th- and early 20th-century philosophy such as Kierkegaard, Karl Jaspers, and Heidegger. He also said his work, The Myth of Sisyphus, was a criticism of various aspects of existentialism. Camus was rejecting existentialism as a philosophy, but his critique was mostly focused on Sartrean existentialism, and to a lesser extent on religious existentialism. He thought that the importance of history held by Marx and Sartre was incompatible with his belief in human freedom. David Sherman and others also suggest the rivalry between Sartre and Camus also played a part in his rejection of existentialism. David Simpson argues further that his humanism and belief in human nature set him apart from the existentialist doctrine that existence precedes essence. On the other hand, Camus focused most of his philosophy around existential questions. The absurdity of life, the inevitable ending (death) is highlighted in his acts. His belief was that the absurd—life being void of meaning, or man's inability to know that meaning if it were to exist—was something that man should embrace. His anti-Christianity, his commitment to individual moral freedom and responsibility are only a few of the similarities with other existential writers. More importantly, Camus addressed one of the fundamental questions of existentialism: the problem of suicide. He wrote: "There is only one really serious philosophical question, and that is suicide." Camus viewed the question of suicide as arising naturally as a solution to the absurdity of life. Absurdism Many existentialist writers have addressed the Absurd, each with their own interpretation of what it is and what makes it important. Kierkegaard explains that the absurdity of religious truths prevents us from reaching God rationally. Sartre recognizes the absurdity of individual experience. Camus's thoughts on the Absurd begin with his first cycle of books and the literary essay The Myth of Sisyphus, (Le Mythe de Sisyphe), his major work on the subject. In 1942, he published the story of a man living an absurd life in The Stranger. He also wrote a play about the Roman emperor Caligula, pursuing an absurd logic, which was not performed until 1945. His early thoughts appeared in his first collection of essays, L'Envers et l'endroit (Betwixt and Between) in 1937. Absurd themes were expressed with more sophistication in his second collection of essays, Noces (Nuptials) in 1938. In these essays, Camus reflects on the experience of the Absurd. Aspects of the notion of the Absurd can be found in The Plague. Camus follows Sartre's definition of the Absurd: "That which is meaningless. Thus man's existence is absurd because his contingency finds no external justification". The Absurd is created because man, who is placed in an unintelligent universe, realises that human values are not founded on a solid external component; or as Camus himself explains, the Absurd is the result of the "confrontation between human need and the unreasonable silence of the world." Even though absurdity is inescapable, Camus does not drift towards nihilism. But the realization of absurdity leads to the question: Why should someone continue to live? Suicide is an option that Camus firmly dismisses as the renunciation of human values and freedom. Rather, he proposes we accept that absurdity is a part of our lives and live with it. The turning point in Camus's attitude to the Absurd occurs in a collection of four letters to an anonymous German friend, written between July 1943 and July 1944. The first was published in the Revue Libre in 1943, the second in the Cahiers de Libération in 1944, and the third in the newspaper Libertés, in 1945. The four letters were published as Lettres à un ami allemand (Letters to a German Friend) in 1945, and were included in the collection Resistance, Rebellion, and Death. Camus regretted the continued reference to himself as a "philosopher of the absurd". He showed less interest in the Absurd shortly after publishing Le Mythe de Sisyphe. To distinguish his ideas, scholars sometimes refer to the Paradox of the Absurd, when referring to "Camus's Absurd". Revolt Camus is known for articulating the case for revolting against any kind of oppression, injustice, or whatever disrespects the human condition. He is cautious enough, however, to set the limits on the rebellion. L'Homme révolté (The Rebel) explains in detail his thoughts on the issue. There, he builds upon the absurd (described in The Myth of Sisyphus) but goes further. In the introduction, where he examines the metaphysics of rebellion, he concludes with the phrase "I revolt, therefore we exist" implying the recognition of a common human condition. Camus also delineates the difference between revolution and rebellion and notices that history has shown that the rebel's revolution might easily end up as an oppressive regime; he therefore places importance on the morals accompanying the revolution. Camus poses a crucial question: Is it possible for humans to act in an ethical and meaningful manner, in a silent universe? According to him the answer is yes, as the experience and awareness of the Absurd creates the moral values and also sets the limits of our actions. Camus separates the modern form of rebellion into two modes. First, there is the metaphysical rebellion, which is "the movement by which man protests against his condition and against the whole of creation." The other mode, historical rebellion, is the attempt to materialize the abstract spirit of metaphysical rebellion and change the world. In this attempt, the rebel must balance between the evil of the world and the intrinsic evil which every revolt carries, and not cause any unjustifiable suffering. Legacy Camus's novels and philosophical essays are still influential. After his death, interest in Camus followed the rise (and diminution) of the New Left. Following the collapse of the Soviet Union, interest in his alternative road to communism resurfaced. He is remembered for his skeptical humanism and his support for political tolerance, dialogue, and civil rights. Although Camus has been linked to anti-Soviet communism, reaching as far as anarcho-syndicalism, some neo-liberals have tried to associate him with their policies; for instance, the French President Nicolas Sarkozy suggested that his remains be moved to the Panthéon, an idea that was criticised by Camus's surviving family and angered many on the Left. Tributes In Tipasa (Algeria), inside the Roman ruins, facing the sea and Mount Chenoua, a stele was erected in 1961 in honor of Albert Camus with this phrase in French extracted from his work Noces à Tipasa: "I understand here what is called glory: the right to love beyond measure " (« Je comprends ici ce qu'on appelle gloire : le droit d'aimer sans mesure. »). The French Post published a stamp with his effigy on 26 June 1967.

https://en.wikipedia.org/wiki/Analog%20signal

Analog signal

An analog signal is any continuous signal representing some other quantity, i.e., analogous to another quantity. For example, in an analog audio signal, the instantaneous signal voltage varies continuously with the pressure of the sound waves. In contrast, a digital signal represents the original time-varying quantity as a sampled sequence of quantized values which imposes some bandwidth and dynamic range constraints on the representation. The term analog signal usually refers to electrical signals; however, mechanical, pneumatic, hydraulic and other systems may also convey or be considered analog signals. Representation An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information. Any information may be conveyed by an analog signal; such a signal may be a measured response to changes in a physical variable, such as sound, light, temperature, position, or pressure. The physical variable is converted to an analog signal by a transducer. For example, sound striking the diaphragm of a microphone induces corresponding fluctuations in the current produced by a coil in an electromagnetic microphone or the voltage produced by a condenser microphone. The voltage or the current is said to be an analog of the sound. Noise An analog signal is subject to electronic noise and distortion introduced by communication channels, recording and signal processing operations, which can progressively degrade the signal-to-noise ratio (SNR). As the signal is transmitted, copied, or processed, the unavoidable noise introduced in the signal path will accumulate as a generation loss, progressively and irreversibly degrading the SNR, until in extreme cases, the signal can be overwhelmed. Noise can show up as hiss and intermodulation distortion in audio signals, or snow in video signals. Generation loss is irreversible as there is no reliable method to distinguish the noise from the signal. In contrast, although converting an analog signal to digital form introduces a low-level quantization noise into the signal due to finite resolution of digital systems, once in digital form, the signal can be transmitted, stored, or processed without introducing significant additional noise or distortion. Noise accumulation in analog systems can be minimized by electromagnetic shielding, balanced lines, low-noise amplifiers and high-quality electrical components. In analog systems, it is difficult to detect when such degradation occurs. However, in digital systems, degradation can not only be detected but corrected as well.

https://en.wikipedia.org/wiki/Miss%20Marple

Miss Marple

Miss Marple is a fictional character in Agatha Christie's crime novels and short stories. Jane Marple lives in the village of St. Mary Mead and acts as an amateur consulting detective. Often characterized as an elderly spinster, she is one of Christie's best-known characters and has been portrayed numerous times on screen. Her first appearance was in a short story published in The Royal Magazine in December 1927, "The Tuesday Night Club", which later became the first chapter of The Thirteen Problems (1932). Her first appearance in a full-length novel was in The Murder at the Vicarage in 1930, and her last appearance was in Sleeping Murder in 1976. Origins The character of Miss Marple is based on friends of Christie's step grandmother/aunt (Margaret Miller, née West). Christie attributed the inspiration for the character to multiple sources, stating that Miss Marple was "the sort of old lady who would have been rather like some of my step grandmother's Ealing cronies – old ladies whom I have met in so many villages where I have gone to stay as a girl". Christie also used material from her fictional creation, spinster Caroline Sheppard, who appeared in The Murder of Roger Ackroyd. When Michael Morton adapted the novel for the stage, he replaced the character of Caroline with a young girl. This change saddened Christie and she determined to give old maids a voice: Miss Marple was born. Christie is popularly believed to have taken the name from Marple railway station, through which she passed, though a letter she wrote to a fan appears to prove that the name was inspired by a visit to a sale at Marple Hall in the same town, near her sister Margaret Watts' home at Abney Hall. Character The character of Jane Marple in the first Miss Marple book, The Murder at the Vicarage, is markedly different from how she appears in later books. This early version of Miss Marple is a gleeful gossip and not an especially nice woman. The citizens of St. Mary Mead like her but are often tired of her nosy nature and the fact she seems to expect the worst of everyone. In later books, she becomes a kinder and more modern person. Miss Marple solves difficult crimes thanks to her shrewd intelligence, and St. Mary Mead, over her lifetime, has given her seemingly infinite examples of the negative side of human nature. Crimes always remind her of a previous incident, although acquaintances may be bored by analogies that often lead her to a deeper realisation about the true nature of a crime. She also has a remarkable ability to latch onto a casual comment and connect it to the case at hand. In several stories, she is able to rely on her acquaintance with Sir Henry Clithering, a retired commissioner of the Metropolitan Police, for official information when required. Miss Marple never married and has no close living relatives. Her nephew, the "well-known author" Raymond West (A Caribbean Mystery, 1964), appears in some stories, including The Thirteen Problems, Sleeping Murder, and Ingots of Gold (which also feature his wife, Joyce Lemprière). Raymond overestimates himself and underestimates his aunt's mental acuity. Miss Marple employs young women (including Clara, Emily, Alice, Esther, Gwenda, and Amy) from a nearby orphanage, whom she trains for service as general housemaids after the retirement of her long-time maid-housekeeper, faithful Florence. She was briefly looked after by her irritating companion, Miss Knight. In her later years, companion Cherry Baker, first introduced in The Mirror Crack'd From Side to Side, lives in. Miss Marple has never worked for her living and is of independent means, although she benefits in her old age from the financial support of her nephew Raymond. She is not from the aristocracy or landed gentry, but is quite at home among them; as a gentlewoman, Miss Marple may thus be considered a female version of the gentleman detective, a staple of British detective fiction. She demonstrates a remarkably thorough education, including some art courses that involved the study of human anatomy using human cadavers. In They Do It with Mirrors (1952), it is revealed that Miss Marple grew up in a cathedral close, and that she studied at an Italian finishing school with Americans Ruth Van Rydock and Caroline "Carrie" Louise Serrocold. While Miss Marple is described as "an old lady" in many of the stories, her age is rarely mentioned and is not consistently presented. In At Bertram's Hotel, published in 1965, it is said she visited the hotel when she was 14 and almost 60 years have passed since then, implying that she's nearly 75 years old but in 4:50 from Paddington, published almost a decade earlier in 1957, she says she will be "90 next year." Excluding Sleeping Murder, 41 years passed between the first and last-written novels, and many characters grow and age. An example would be the Vicar's nephew: in The Murder at the Vicarage, the Reverend Mr Clement's nephew Dennis is a teenager; in The Mirror Crack'd from Side to Side, it is mentioned that the nephew is now an adult and has a successful career. The effects of ageing are seen on Miss Marple, such as needing a holiday after illness in A Caribbean Mystery, but she is if anything more agile in Nemesis, set only 16 months later. Miss Marple's background is described in some detail, albeit in glimpses across the novels and short stories in which she appears. She has a very large family, including a sister, the mother of Raymond, and Mabel Denham, a young woman who was accused of poisoning her husband Geoffrey (The Thumb Mark of St. Peter).

McManus, Dreda Say Mitchell, Kate Mosse, and Ruth Ware (published 2022) Books about Miss Marple The Life and Times of Miss Jane Marple – a biography by Anne Hart Stage A stage adaptation of Murder at the Vicarage, by Moie Charles and Barbara Toy, was first seen at Northampton on 17 October 1949; it was directed by Reginald Tate, starred the 35-year-old Barbara Mullen as Miss Marple, and after touring, reached the Playhouse Theatre in London's West End on 14 December. Having run till late March 1950, it then went on tour again. In July 1974, Mullen (by then 60) returned to the role in another national tour of the same play, culminating 12 months later when the show opened at London's Savoy Theatre on 28 July 1975. At the end of March 1976, the Miss Marple role was taken over by Avril Angers, after which the production transferred to the Fortune Theatre on 5 July. The role then passed to Muriel Pavlow in June 1977 and to Gabrielle Hamilton late the following year; the production finally closed in October 1979. On 21 September 1977, while Murder at the Vicarage was still running at the Fortune, a stage adaptation by Leslie Darbon of A Murder Is Announced opened at the Vaudeville Theatre, with Dulcie Gray as Miss Marple. The show ran to the end of September 1978 and then toured. Films Margaret Rutherford Margaret Rutherford played Miss Marple in four films directed by George Pollock between 1961 and 1964. These were successful light comedies, but Christie herself was disappointed with them. Nevertheless, Agatha Christie dedicated the novel The Mirror Crack'd from Side to Side to Rutherford. Rutherford presented the character as a bold and eccentric old lady, different from the prim and birdlike character Christie created in her novels. As penned by Christie, Miss Marple has never worked for a living, but the character as portrayed by Margaret Rutherford briefly works as a cook-housekeeper, a stage actress, a sailor and criminal reformer, and is offered the chance to run a riding establishment-cum-hotel. Her education and genteel background are hinted at when she mentions her awards at marksmanship, fencing, and equestrianism (although these hints are played for comedic value). Murder, She Said (1961) was the first of the four British MGM productions starring Rutherford. This film was based on the 1957 novel 4:50 from Paddington (U.S. title, What Mrs. McGillicuddy Saw!), and the changes made in the plot were typical of the series. In the film, Mrs. McGillicuddy is cut from the plot. Miss Marple herself sees an apparent murder committed on a train running alongside hers. Actress Joan Hickson, who played Marple in the 1984–1992 television adaptations, has a role as a housekeeper in this movie. Murder at the Gallop (1963), based on the 1953 Hercule Poirot novel After the Funeral (in this film, she is identified as Miss JTV Marple, though there was no indication as to what the extra initials might stand for). Murder Most Foul (1964), based on the 1952 Poirot novel Mrs McGinty's Dead. Murder Ahoy! (1964). The last film is not based on any Christie work but displays a few plot elements from They Do It With Mirrors (viz., the ship is used as a reform school for wayward boys and one of the teachers uses them as a crime force), and there is a kind of salute to The Mousetrap. The music to all four films was composed and conducted by Ron Goodwin. The same theme is used on all four films with slight variations in each. The score was written within a couple of weeks by Goodwin who was approached by Pollock after Pollock had heard about him from Stanley Black. Black had worked with Pollock on Stranger in Town in 1957 and had previously hired Goodwin as his orchestrator. Rutherford, who was 68 years old when the first film was shot in February 1961, insisted that she wear her own clothes during the filming of the movie, as well as having her husband, Stringer Davis, appear alongside her as the character Mr Stringer. The Rutherford films are frequently repeated on television in Germany, and in that country Miss Marple is generally identified with Rutherford's quirky portrayal. Rutherford also appeared briefly as Miss Marple in the parodic Hercule Poirot adventure The Alphabet Murders (1965). Angela Lansbury In 1980, Angela Lansbury played Miss Marple in The Mirror Crack'd (EMI, directed by Guy Hamilton), based on Christie's 1962 novel. The film featured an all-star cast that included Elizabeth Taylor, Rock Hudson, Geraldine Chaplin, Tony Curtis, and Kim Novak. Edward Fox appeared as Inspector Craddock, who did Miss Marple's legwork. Lansbury's Marple was a crisp, intelligent woman who moved stiffly and spoke in clipped tones. Unlike most incarnations of Miss Marple, this one smoked cigarettes. Lansbury was later cast as Jessica Fletcher in Murder, She Wrote, a similar role. Television American TV was the setting for the first screen portrayal of Miss Marple with Gracie Fields, the British actress and singer, playing her in a 1956 episode of Goodyear TV Playhouse based on A Murder Is Announced, the 1950 Christie novel. In 1970, the character of Miss Marple was portrayed by Inge Langen in a West German television adaptation of The Murder at the Vicarage (Mord im Pfarrhaus). In 2015, CBS planned a "much younger" version of the character, a granddaughter who takes over a California bookstore. In 2018, Miss Marple was portrayed by Yunjin Kim in the South Korean television series Ms. Ma, Nemesis. Helen Hayes American stage and screen actress Helen Hayes portrayed Miss Marple in two American television films near the end of her decades-long acting career, both for CBS: A Caribbean Mystery (1983) and Murder with Mirrors (1985). Sue Grafton contributed to the screenplay of the former. Hayes's Marple was benign and chirpy. She had earlier appeared in a television film adaptation of the non-Marple Christie story Murder Is Easy, playing an elderly lady somewhat similar to Miss Marple. Joan Hickson From 1984 to 1992, the BBC adapted all of the original Miss Marple novels as a series titled Miss Marple. Joan Hickson played the lead role. In the 1940s, she had appeared on stage in an Agatha Christie play, Appointment with Death, which was seen by Christie who wrote in a note to her, "I hope one day you will play my dear Miss Marple". She portrayed a maid in the 1937 film, Love from a Stranger, which starred Ann Harding and Basil Rathbone, another Agatha Christie play adaptation. As well as portraying Miss Marple on television, Hickson narrated Miss Marple stories for audio books. In the "Binge!" article of Entertainment Weekly Issue #1343–1344 (26 December 2014 – 3 January 2015), the writers picked Hickson as "Best Marple" in the "Hercule Poirot & Miss Marple" timeline.

Geraldine McEwan starred in the first three series. Julia McKenzie took over the role in the fourth season. The adaptations change the plots and characters of the original books (e.g. incorporating lesbian affairs, changing the identities of some killers, renaming or removing significant characters, and even using stories from other books in which Miss Marple did not originally feature). In the Geraldine McEwan series it is revealed that when she was young (portrayed by Julie Cox in a flashback), Miss Marple had an affair with a married soldier, Captain Ainsworth, who was killed in action in World War I, in December 1915. It is also said (in A Murder Is Announced) that she served as an ambulance driver during World War I.

The anime series dramatised the following Miss Marple stories: Strange Jest (EP 3) The Case of the Perfect Maid (EP 4) The Tape-Measure Murder (EP 13) Ingots of Gold (EP 14) The Blue Geranium (EP 15) 4.50 from Paddington (EP 21–24) Motive versus Opportunity (EP 27) Sleeping Murder (EP 30–33) Radio June Whitfield starred as Miss Marple in Michael Bakewell's adaptations of all twelve novels, broadcast on BBC Radio 4 between 1993 and 2001. Three short stories with Whitfield ("Tape-Measure Murder", "The Case of the Perfect Maid" and "Sanctuary") were later broadcast under the collective title Miss Marple's Final Cases weekly 16 – 30 September 2015. Other appearances Marple was highlighted in volume 20 of the Case Closed manga's edition of "Gosho Aoyama's Mystery Library", a section of the graphic novels (usually the last page) where the author introduces a different detective (or occasionally, a villain) from mystery literature, television, or other media. In the 1976 Neil Simon spoof Murder by Death, Miss Marple is parodied as "Miss Marbles" by Elsa Lanchester.

April

April is the fourth month of the year in the Gregorian and Julian calendars. It is the first of four months to have a length of 30 days, and the second of five months to have a length of less than 31 days. April is commonly associated with the season of spring in the Northern Hemisphere, and autumn in the Southern Hemisphere, where it is the seasonal equivalent to October in the Northern Hemisphere and vice versa. History The Romans gave this month the Latin name Aprilis but the derivation of this name is uncertain. The traditional etymology is from the verb aperire, "to open", in allusion to its being the season when trees and flowers begin to "open", which is supported by comparison with the modern Greek use of άνοιξη (ánixi) (opening) for spring. Since some of the Roman months were named in honor of divinities, and as April was sacred to the goddess Venus, her Veneralia being held on the first day, it has been suggested that Aprilis was originally her month Aphrilis, from her equivalent Greek goddess name Aphrodite (Aphros), or from the Etruscan name Apru. Jacob Grimm suggests the name of a hypothetical god or hero, Aper or Aprus. April was the second month of the earliest Roman calendar, before Ianuarius and Februarius were added by King Numa Pompilius about 700 BC. It became the fourth month of the calendar year (the year when twelve months are displayed in order) during the time of the decemvirs about 450 BC, when it also was given 29 days. The 30th day was added during the reform of the calendar undertaken by Julius Caesar in the mid-40s BC, which produced the Julian calendar. The Anglo-Saxons called April ēastre-monaþ. The Venerable Bede says in The Reckoning of Time that this month ēastre is the root of the word Easter. He further states that the month was named after a goddess Eostre whose feast was in that month. It is also attested by Einhard in his work, Vita Karoli Magni. St George's day is the twenty-third of the month; and St Mark's Eve, with its superstition that the ghosts of those who are doomed to die within the year will be seen to pass into the church, falls on the twenty-fourth. In China the symbolic of the earth by the emperor and princes of the blood took place in their third month, which frequently corresponds to April. In Finnish April is huhtikuu, meaning slash-and-burn moon, when gymnosperms for beat and burn clearing of farmland were felled. In Slovene, the most established traditional name is mali traven, meaning the month when plants start growing. It was first written in 1466 in the Škofja Loka manuscript. The month Aprilis had 30 days; Numa Pompilius made it 29 days long; finally Julius Caesar’s calendar reform made it again 30 days long, which was not changed in the calendar revision of Augustus Caesar in 8 BC. Additionally in the Spanish colony, Las Islas Filipinas (now known as the Philippines), the month Aprilis had a significant meaning to the life of the natives as it was associated to the influence of the Chinese during the Spanish colonial period. The importance of this aspect to the lives of the natives was formerly associated to an event called "Abril na Ikaw" as it is closely linked to the famous trader, April Yu. In Ancient Rome, the festival of Cerealia was held for seven days from mid-to-late April, but exact dates are uncertain. Feriae Latinae was also held in April, with the date varying. Other ancient Roman observances include Veneralia (April 1), Megalesia (April 10–16), Fordicidia (April 15), Parilia (April 21), Vinalia Urbana (April 23), Robigalia (April 25), and Serapia (April 25). Floralia was held April 27 during the Republican era, or April 28 on the Julian calendar, and lasted until May 3. However, these dates do not correspond to the modern Gregorian calendar. The Lyrids meteor shower appears on April 16 – April 26 each year, with the peak generally occurring on April 22. Eta Aquariids meteor shower also appears in April. It is visible from about April 21 to about May 20 each year with peak activity on or around May 6. The Pi Puppids appear on April 23, but only in years around the parent comet's perihelion date. The Virginids also shower at various dates in April. The "Days of April" (journées d'avril) is a name assigned in French history to a series of insurrections at Lyons, Paris and elsewhere, against the government of Louis Philippe in 1834, which led to violent repressive measures, and to a famous trial known as the procès d'avril. April symbols April's birthstone is the diamond. The birth flower is typically listed as either the common daisy (Bellis perennis) or the sweet pea. The zodiac signs for the month of April are Aries (until April 19) and Taurus (April 20 onwards). April observances This list does not necessarily imply either official status nor general observance.

Anatoly Karpov

Anatoly Yevgenyevich Karpov (; born May 23, 1951) is a Russian and former Soviet chess grandmaster, former World Chess Champion, ⁣and politician. He was the 12th World Chess Champion from 1975 to 1985, a three-time FIDE World Champion (1993, 1996, 1998), twice World Chess champion as a member of the USSR team (1985, 1989), and a six-time winner of Chess Olympiads as a member of the USSR team (1972, 1974, 1980, 1982, 1986, 1988). The International Association of Chess Press awarded him nine Chess Oscars (1973, 1974, 1975, 1976, 1977, 1979, 1980, 1981, 1984). Karpov's chess tournament successes include over 160 first-place finishes. He had a peak Elo rating of 2780, and his 102 total months at world number one is the third-longest of all time, behind Magnus Carlsen and Garry Kasparov, since the inception of the FIDE ranking list in 1970. Karpov is also an elected Member of the State Duma in Russia. Since 2006, he has chaired the Commission for Ecological Safety and Environmental Protection of the Civic Chamber of the Russian Federation, and since 2007, he has been a member of the Public Council under the Ministry of Defence. Early life Karpov was born into a Russian family on May 23, 1951, in Zlatoust, in the Urals region of the former Soviet Union, and learned to play chess at the age of four. His early rise in chess was swift, as he became a candidate master by age 11. At 12, he was accepted into Mikhail Botvinnik's prestigious chess school, though Botvinnik made the following remark about the young Karpov: "The boy does not have a clue about chess, and there's no future at all for him in this profession." Karpov acknowledged that his understanding of chess theory was very confused at that time, and later wrote that the homework Botvinnik assigned greatly helped him, since it required that he consult chess books and work diligently. Karpov improved so quickly under Botvinnik's tutelage that he became the youngest Soviet master in history at the age of fifteen in 1966; this tied the record established by Boris Spassky in 1952. Career Young master Karpov finished first in his first international tournament, in Třinec, several months later, ahead of Viktor Kupreichik. In 1967, he won the annual Niemeyer Tournament in Groningen. Karpov won a gold medal for academic excellence in high school, and entered Moscow State University in 1968 to study mathematics. He later transferred to Leningrad State University, eventually graduating from there in economics. One reason for the transfer was to be closer to his coach, grandmaster Semyon Furman, who lived in Leningrad. In his writings, Karpov credits Furman as a major influence on his development as a world-class player. In 1969, Karpov became the first Soviet player since Spassky (1955) to win the World Junior Championship, scoring an undefeated 10/11 in the final A group at Stockholm. This victory earned him the International Master title. In 1970, Karpov tied for fourth and fifth places with Pal Benko at an international tournament in Caracas, Venezuela, and earned the international grandmaster title. FIDE awarded him the title during its 41st congress, held during the Chess Olympiad in Siegen, West Germany in September 1970. Grandmaster Karpov won the 1971 Alekhine Memorial tournament in Moscow (jointly with Leonid Stein), ahead of a star-studded field, for his first significant adult victory. His Elo rating shot from 2540 in 1971 to 2660 in 1973, during which he shared second place in the 1973 Soviet championship, one point behind Spassky, and qualified for the Leningrad Interzonal. Candidate Karpov's world junior championship qualified him for one of the two Interzonals, a stage in the 1975 World Championship cycle to choose the challenger to play world champion Bobby Fischer. He finished equal first in the Leningrad Interzonal, qualifying for the 1974 Candidates Matches. Karpov defeated Lev Polugaevsky by the score of +3=5 in the first Candidates' match, earning the right to face former champion Boris Spassky in the semifinal round. Karpov was on record saying that he believed Spassky would easily beat him and win the Candidates' cycle to face Fischer, and that he (Karpov) would win the following Candidates' cycle in 1977. Spassky won the first game as Black in good style, but tenacious, aggressive play from Karpov secured him overall victory by +4−1=6. The Candidates' final was played in Moscow with Victor Korchnoi. Karpov took an early lead, winning the second game against the Sicilian Dragon, then scoring another victory in the sixth game. Following ten consecutive draws, Korchnoi threw away a winning position in the seventeenth game to give Karpov a 3–0 lead. In game 19, Korchnoi succeeded in winning a long endgame, then notched a speedy victory after a blunder by Karpov two games later. Three more draws, the last agreed by Karpov in a clearly better position, closed the match, as he thus prevailed +3−2=19, moving on to challenge Fischer for the world title. Match with Fischer in 1975 Though a world championship match between Karpov and Fischer was highly anticipated, those hopes were never realised. Fischer not only insisted that the match be the first to ten wins (draws not counting), but also that the champion retain the crown if the score was tied 9–9. FIDE, the International Chess Federation, refused to allow this proviso, and gave both players a deadline of April 1, 1975, to agree to play the match under the FIDE-approved rules. When Fischer did not agree, FIDE President Max Euwe declared on April 3, 1975, that Fischer had forfeited his title and Karpov was the new World Champion. Karpov later attempted to set up another match with Fischer, but the negotiations fell through. This thrust the young Karpov into the role of World Champion without having faced the reigning champion. Garry Kasparov argued that Karpov would have had good chances because he had beaten Spassky convincingly and was a new breed of tough professional, and indeed had higher quality games, while Fischer had been inactive for three years. This view is echoed by Karpov himself. Spassky thought that Fischer would have won in 1975, but Karpov would have qualified again and beaten Fischer in 1978. Karpov has said that if he had had the opportunity to play Fischer for the championship in his twenties, he could have been a much better player as a result. World champion Determined to prove himself a legitimate champion, Karpov participated in nearly every major tournament for the next ten years. He convincingly won the Milan tournament in 1975, and captured his first of three Soviet titles in 1976. He created a phenomenal streak of tournament wins against the strongest players in the world. Karpov held the record for most consecutive tournament victories (9) until it was shattered by Garry Kasparov (14). As a result, most chess professionals soon agreed that Karpov was a legitimate world champion. In 1978, Karpov's first title defence was against Viktor Korchnoi, the opponent he had defeated in the 1973–75 Candidates' cycle; the match was played at Baguio, Philippines, with the winner needing six victories. As in 1974, Karpov took an early lead, winning the eighth game after seven draws to open the match. When the score was +5−2=20 in Karpov's favour, Korchnoi staged a comeback, and won three of the next four games to draw level with Karpov. Karpov then won the very next game to retain the title (+6−5=21). Three years later, Korchnoi reemerged as the Candidates' winner against German finalist Robert Hübner to challenge Karpov in Merano, Italy. Karpov handily won this match, 11–7 (+6−2=10), in what is remembered as the "Massacre in Merano". Karpov's tournament career reached a peak at the Montreal "Tournament of Stars" tournament in 1979, where he finished joint first (+7−1=10) with Mikhail Tal ahead of a field of strong grandmasters completed by Jan Timman, Ljubomir Ljubojević, Boris Spassky, Vlastimil Hort, Lajos Portisch, Robert Hübner, Bent Larsen and Lubomir Kavalek. He dominated Las Palmas in 1977 with 13½/15. He also won the prestigious Bugojno tournament in 1978 (shared), 1980 and 1986, the Linares tournament in 1981 (shared with Larry Christiansen) and 1994, the Tilburg tournament in 1977, 1979, 1980, 1982, and 1983, and the Soviet Championship in 1976, 1983, and 1988. Karpov represented the Soviet Union at six Chess Olympiads, in all of which the USSR won the team gold medal. He played as the first reserve at Skopje 1972, winning the board prize with 13/15. At Nice 1974, he advanced to board one and again won the board prize with 12/14. At La Valletta 1980, he was again board one and scored 9/12. At Lucerne 1982, he scored 6½/8 on board one. At Dubai 1986, he scored 6/9 on board two. His last was Thessaloniki 1988, where on board two he scored 8/10. In Olympiad play, Karpov lost only two games out of 68 played. To illustrate Karpov's dominance over his peers as champion, his score was +11−2=20 versus Spassky, +5=12 versus Robert Hübner, +6−1=16 versus Ulf Andersson, +3−1=10 versus Vasily Smyslov, +1=16 versus Mikhail Tal, and +10−2=13 versus Ljubomir Ljubojević. Rivalry with Kasparov Karpov had cemented his position as the world's best player and world champion by the time Garry Kasparov arrived on the scene. In their first match, the World Chess Championship 1984 in Moscow, the first player to win six games would win the match. Karpov built a 4–0 lead after nine games. The next 17 games were drawn, setting a record for world title matches, and it took Karpov until game 27 to gain his fifth win. In game 31, Karpov had a winning position but failed to take advantage and settled for a draw. He lost the next game, after which 14 more draws ensued. Karpov held a solidly winning position in Game 41, but again blundered and had to settle for a draw. After Kasparov won games 47 and 48, FIDE President Florencio Campomanes unilaterally terminated the match, citing the players' health. Karpov is said to have lost 10 kg over the course of the match. The match had lasted an unprecedented five months, with five wins for Karpov, three for Kasparov, and 40 draws. A rematch was set for later in 1985, also in Moscow. The events of the so-called Marathon Match forced FIDE to return to the previous format, with a match limited to 24 games (with Karpov remaining champion if the match finished 12–12). Karpov needed to win the final game to draw the match and retain his title, but lost, surrendering the title to his opponent. The final score was 13–11 (+3−5=16) in favour of Kasparov. Karpov remained a formidable opponent (and the world No. 2) until the mid-1990s. He fought Kasparov in three more world championship matches in 1986 (held in London and Leningrad), 1987 (in Seville), and 1990 (in New York City and Lyon). All three matches were extremely close: the scores were 11½–12½ (+4−5=15), 12–12 (+4−4=16), and 11½–12½ (+3−4=17). In all three matches, Karpov had winning chances up to the last games. The ending of the 1987 Seville match was particularly dramatic. Karpov won the 23rd game when Kasparov miscalculated a combination. In the final game, needing only a draw to win the title, Karpov cracked under time pressure at the end of the first session of play, missed a variation leading to an almost forced draw, and allowed Kasparov to adjourn the game with an extra pawn. After a further mistake in the second session, Karpov was slowly ground down and resigned on move 64, ending the match and allowing Kasparov to keep the title. In their five world championship matches, Karpov scored 19 wins, 21 losses, and 104 draws in 144 games. Overall, Karpov played five matches against Kasparov for the title from 1984 to 1990 without ever defeating him in a match. FIDE champion again (1993–1999) In 1992, Karpov lost a Candidates Match against Nigel Short. But in the World Chess Championship 1993, Karpov reacquired the FIDE World Champion title when Kasparov and Short split from FIDE. Karpov defeated Timman – the loser of the Candidates' final against Short. The next major meeting of Kasparov and Karpov was the 1994 Linares chess tournament. The field, in eventual finishing order, was Karpov, Kasparov, Shirov, Bareev, Kramnik, Lautier, Anand, Kamsky, Topalov, Ivanchuk, Gelfand, Illescas, Judit Polgár, and Beliavsky; with an average Elo rating of 2685, the highest ever at that time. Impressed by the strength of the tournament, Kasparov had said several days before the tournament that the winner could rightly be called the world champion of tournaments. Perhaps spurred on by this comment, Karpov played the best tournament of his life. He was undefeated and earned 11 points out of 13 (the best world-class tournament winning percentage since Alekhine won San Remo in 1930), finishing 2½ points ahead of second-place Kasparov and Shirov. Many of his wins were spectacular (in particular, his win over Topalov is considered possibly the finest of his career). This performance against the best players in the world put his Elo rating tournament performance at 2985, the highest performance rating of any player in history up until 2009, when Magnus Carlsen won the category XXI Pearl Spring chess tournament with a performance of 3002. Chess statistician Jeff Sonas considers Karpov's Linares performance the best tournament result in history. Karpov defended his FIDE title against the rising star Gata Kamsky (+6−3=9) in 1996. In 1998, FIDE largely scrapped the old system of Candidates' Matches, instead having a large knockout event in which a large number of players contested short matches against each other over just a few weeks. In the first of these events, the FIDE World Chess Championship 1998, champion Karpov was seeded straight into the final, defeating Viswanathan Anand (+2−2=2, rapid tiebreak 2–0). In the subsequent cycle, the format was changed, with the champion having to qualify. Karpov refused to defend his title, and ceased to be FIDE World Champion after the FIDE World Chess Championship 1999. Towards retirement Karpov's classical tournament play has been seriously limited since 1997, since he prefers to be more involved in Russian politics. He had been a member of the Supreme Soviet Commission for Foreign Affairs and the president of the Soviet Peace Fund before the Soviet Union dissolved. In addition, he has been involved in several disputes with FIDE. In the September 2009 FIDE rating list, he dropped out of the world's Top 100 for the first time. Karpov usually limits his play to exhibition events, and has revamped his style to specialize in rapid chess. In 2002, he won a match against Kasparov, defeating him in a rapid time control match 2½–1½. In 2006, he tied for first with Kasparov in a blitz tournament, ahead of Korchnoi and Judit Polgár. Karpov and Kasparov played a mixed 12-game match from September 21–24, 2009, in Valencia, Spain. It consisted of four rapid (or semi-rapid) and eight blitz games and took place exactly 25 years after the two players' legendary encounter at the World Chess Championship 1984. Kasparov won the match 9–3. Karpov played a match against Yasser Seirawan in 2012 in St. Louis, Missouri, an important center of the North American chess scene, winning 8–6 (+5−3=6). In November 2012, he won the Cap d'Agde rapid tournament that bears his name (Anatoly Karpov Trophy), beating Vasyl Ivanchuk (ranked 9th in the October 2012 FIDE world rankings) in the final. Professional and political career after retirement from chess In 2003, Karpov opened his first American chess school in Lindsborg, Kansas. On March 2, 2022, the school announced a name change to International School of Chess of the Midwest due to the 2022 Russian invasion of Ukraine. Karpov has been a member of the sixth, seventh and eighth Russian State Dumas. Since 2005, he has been a member of the Public Chamber of Russia. He has involved himself in several humanitarian causes, such as advocating the use of iodised salt. On December 17, 2012, Karpov supported the law in the Russian Parliament banning adoption of Russian orphans by U.S. citizens. Karpov expressed support of the annexation of Crimea by the Russian Federation, and accused Europe of trying to demonize Putin. In August 2019, Maxim Dlugy said that Karpov had been waiting since March for the approval of a non-immigrant visa to the United States, despite frequently visiting the country since 1972. Karpov had been scheduled to teach a summer camp at the Chess Max Academy. Dlugy said that Karpov had been questioned at the US embassy in Moscow about whether he planned to communicate with American politicians. Karpov was among the Russian State Duma members placed under sanctions by the EU during the prelude to the 2022 Russian invasion of Ukraine. In March 2022, after the start of the invasion, the FIDE Council suspended Karpov's title of FIDE Ambassador for Life. In November 2022, Karpov received a head injury that left him concussed; according to some sources, he was placed in an induced coma. Sources vary on the cause of the injury, including allegations that he was attacked while heavily intoxicated. Karpov's daughter Sofia claimed that he had accidentally fallen; this was echoed by the Russian Chess Federation. Candidate for FIDE presidency In March 2010, Karpov announced that he would be a candidate for the presidency of FIDE. The election took place in September 2010 at the 39th Chess Olympiad. In May, a fundraising event took place in New York with the participation of Kasparov and Magnus Carlsen, who both supported his bid and campaigned for him. Nigel Short also supported Karpov's candidacy. On September 29, 2010, Kirsan Ilyumzhinov was reelected as president of FIDE, 95 votes to 55. Style Karpov's "boa constrictor" playing style is solidly positional, taking minimal risks but reacting mercilessly to the slightest error by his opponent. As a result, he is often compared to José Raúl Capablanca, the third world champion. Karpov himself describes his style as follows:Let us say the game may be continued in two ways: one of them is a beautiful tactical blow that gives rise to variations that don't yield to precise calculations; the other is clear positional pressure that leads to an endgame with microscopic chances of victory.... I would choose [the latter] without thinking twice. If the opponent offers keen play I don't object; but in such cases I get less satisfaction, even if I win, than from a game conducted according to all the rules of strategy with its ruthless logic. Notable games Viktor Korchnoi vs. Anatoly Karpov, Moscow 1973 Karpov sacrifices a pawn for a strong center and attack. Anatoly Karpov vs. Gyula Sax, Linares 1983 Karpov sacrifices for an attack that wins the game 20 moves later, after another spectacular sacrifice from Karpov and counter-sacrifice from Sax. It won the tournament's first . This was not the first time Karpov used the sharp Keres Attack (6.g4) – see his win in Anatoly Karpov vs. Vlastimil Hort, Alekhine Memorial Tournament, Moscow 1971. Anatoly Karpov vs. Veselin Topalov, Dos Hermanas 1994 This game features a sham sacrifice of two pieces, which Karpov regains with a variation, culminating in the win of an exchange with a technically won endgame. Hobbies Karpov's extensive stamp collection of Belgian philately and Belgian Congo stamps and postal history covering mail from 1742 through 1980 was sold by David Feldman's auction company between December 2011 and 2012. He is also known to have large chess stamp and chess book collections. His private chess library consists of 9,000 books. Honours and awards Order of Merit for the Fatherland, 3rd class (2001) – for outstanding contribution to the implementation of charitable programmes, the strengthening of peace and friendship between the peoples Order of Friendship (2011) – for his great contribution to strengthening peace and friendship between peoples and productive social activities Order of Lenin (1981) Order of the Red Banner of Labour (1978) Order of Merit, 2nd class (Ukraine) (November 13, 2006) – for his contribution to the victims of the Chernobyl disaster Order of Holy Prince Daniel of Moscow, 2nd class (1996) Order of St. Sergius of Radonezh, 2nd class (2001) Medal "For outstanding contribution to the Collector business in Russia" Honorary member of the Soviet Philately Society (1979) Diploma of the State Duma of the Russian Federation No. 1 Order "For outstanding achievements in sport" (Republic of Cuba) Medal of Tsiolkovsky Cosmonautics Federation of Russia Medal "For Strengthening the penal system", 1st and 2nd class Breastplate of the 1st degree of the Interior Ministry International Association of Chess Press, 9 times voted the best chess player of the year and awarded the "Chess Oscar" Order of Saint Nestor the Chronicler, 1st class Asteroid 90414 Karpov is named after Karpov Anatoly Karpov International Chess Tournament, an annual round-robin tournament held in his honour in Poikovsky, Khanty-Mansi Autonomous Okrug, Russia since 2000 Books Karpov has authored or co-authored several books, most of which have been translated into English.

Auto racing

Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, England, a distance of . It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the construction of the first successful gasoline-fueled automobiles. The first organized contest was on April 28, 1887, by the chief editor of Paris publication , Monsieur Fossier. It ran from Neuilly Bridge to the Bois de Boulogne. On July 22, 1894, the Parisian magazine organized what is considered to be the world's first motoring competition, from Paris to Rouen. One hundred and two competitors paid a 10-franc entrance fee. The first American automobile race is generally held to be the Thanksgiving Day Chicago Times-Herald race of November 28, 1895. Press coverage of the event first aroused significant American interest in the automobile. The Targa Florio was an open road endurance automobile race held in the mountains of Sicily, Italy near the island's capital of Palermo. Founded in 1906, it was the oldest sports car racing event, part of the World Sportscar Championship between 1955 and 1973. With auto construction and racing dominated by France, the French automobile club ACF staged a number of major international races, usually from or to Paris, connecting with another major city, in France or elsewhere in Europe. Aspendale Racecourse, in Australia, was the world's first purpose-built motor racing circuit, opening in January 1906. The pear-shaped track was close to a mile in length, with slightly banked curves and a gravel surface of crushed cement. Brooklands, in Surrey, England, was the first purpose-built 'banked' motor racing venue, opening in June 1907. It featured a concrete track with high-speed banked corners. One of the oldest existing purpose-built automobile racing circuits in the United States, still in use, is the Indianapolis Motor Speedway in Speedway, Indiana. It is the largest capacity sports venue of any variety worldwide, with a top capacity of some 257,000+ seated spectators. NASCAR was founded by Bill France Sr. on February 21, 1948, with the help of several other drivers of the time. The first NASCAR "Strictly Stock" race ever was held on June 19, 1949, at Daytona Beach, Florida, U.S.. From 1962, sports cars temporarily took a back seat to GT cars, with the (FIA) replacing the World Championship for Sports Cars with the International Championship for GT Manufacturers. From 1962 through 2003, NASCAR's premier series was called the Winston Cup Series, sponsored by R. J. Reynolds Tobacco Company cigarette brand Winston. The changes that resulted from RJR's involvement, as well as the reduction of the schedule from 56 to 34 races a year, established 1972 as the beginning of NASCAR's "modern era". The IMSA GT Series evolved into the American Le Mans Series, which ran its first season in 1998. The European races eventually became the closely related European Le Mans Series, both of which mix prototypes and GTs. (TC) is a popular touring car racing series in Argentina, and one of the oldest car racing series still active in the world. The first TC competition took place in 1931 with 12 races, each in a different province. Future Formula One star Juan Manuel Fangio (Chevrolet) won the 1940 and 1941 editions of the TC. It was during this time that the series' Chevrolet-Ford rivalry began, with Ford acquiring most of its historical victories. Categories Open-wheel racing In single-seater (open-wheel) racing, the wheels are not covered, and the cars often have aerofoil wings front and rear to produce downforce and enhance adhesion to the track. The two most popular varieties of open-wheel road racing are Formula One and the IndyCar Series. In Europe and Asia, open-wheeled racing is commonly referred to as 'Formula', with appropriate hierarchical suffixes. In North America, the 'Formula' terminology is not followed (with the exception of F1). The sport is usually arranged to follow an international format (such as F1), a regional format (such as the Formula 3 Euro Series), and/or a domestic, or country-specific, format (such as the German Formula 3 championship, or the British Formula Ford). F1 is a worldwide series that runs only street circuit and race tracks. These cars are heavily based on technology and their aerodynamics. The speed record was set in 2005 by Juan Pablo Montoya hitting 373 km/h (232 mph). Some of the most prominent races are the Monaco Grand Prix, the Italian Grand Prix, and the British Grand Prix. The season ends with the crowning of the World Championship for drivers and constructors. In the United States, the most popular series is the IndyCar Series. The cars have traditionally been similar to, though less technologically sophisticated than, F1 cars, with more restrictions on technology aimed at controlling costs. While these cars are not as technologically advanced, they are faster, mainly because they compete on oval race tracks, being able to average a lap at 388 km/h (241 mph). The series' biggest race is the Indianapolis 500, which is commonly referred to as "The Greatest Spectacle in Racing" due to being the longest continuously run race and having the largest crowd for a single-day sporting event (350,000+). The other major international single-seater racing series is Formula 2 (formerly known as Formula 3000 and GP2 Series). Regional series include Super Formula and Formula V6 Asia (specifically in Asia), Formula Renault 3.5 (also known as the World Series by Renault, succession series of World Series by Nissan), Formula Three, Formula Palmer Audi and Formula Atlantic. In 2009, the FIA Formula Two Championship brought about the revival of the F2 series. Domestic, or country-specific, series include Formula Three and Formula Renault, with the leading introductory series being Formula Ford. Single-seater racing is not limited merely to professional teams and drivers. There exist many amateur racing clubs. In the UK, the major club series are the Monoposto Racing Club, BRSCC F3 (Formerly ClubF3, formerly ARP F3), Formula Vee and Club Formula Ford. Each series caters to a section of the market, with some primarily providing low-cost racing, while others aim for an authentic experience using the same regulations as the professional series (BRSCC F3). There are other categories of single-seater racing, including kart racing, which employs a small, low-cost machine on small tracks. Many of the current top drivers began their careers in karts. Formula Ford represents the most popular first open-wheel category for up-and-coming drivers stepping up from karts. The series is still the preferred option, as it has introduced an aero package and slicks, allowing the junior drivers to gain experience in a race car with dynamics closer to F1. The Star Mazda Series is another entry-level series. Students at colleges and universities can also take part in single-seater racing through the Formula SAE competition, which involves designing and building a single-seater car in a multidisciplinary team and racing it at the competition. This also develops other soft skills, such as teamwork, while promoting motorsport and engineering. The world's first all-female Formula racing team was created in 2006. The group was an assemblage of drivers from different racing disciplines and formed for an MTV reality pilot, which was shot at Mazda Raceway Laguna Seca. In December 2005, the FIA gave approval to Superleague Formula racing, which debuted in 2008, whereby the racing teams are owned and run by prominent sports clubs such as A.C. Milan and Liverpool F.C. After 25 years away from the sport, former Formula 2 champion Jonathan Palmer reopened the F2 category again; most drivers have graduated from the Formula Palmer Audi series. The category is officially registered as the FIA Formula Two championship. Most rounds have two races and are support races to the FIA World Touring Car Championship. Touring car racing Touring car racing is a style of road racing that is run with production-derived four-seat race cars. The lesser use of aerodynamics means following cars have a much easier time passing than in open-wheel racing. It often features full-contact racing with subtle bumping and nudging due to the small speed differentials and large grids. The major touring car championships conducted worldwide are the Supercars Championship (Australia), British Touring Car Championship, Deutsche Tourenwagen Masters (DTM), World Touring Car Championship and the World Touring Car Cup. The European Touring Car Cup is a one-day event open to Super 2000 specification touring cars from Europe's many national championships. The Sports Car Club of America's SPEED World Challenge Touring Car and GT championships are dominant in North America. America's historic Trans-Am Series is undergoing a period of transition, but is still the longest-running road racing series in the U.S. The National Auto Sport Association also provides a venue for amateurs to compete in home-built factory-derived vehicles on various local circuits. Sports car racing In sports car racing, production-derived versions of two-seat sports cars, also known as grand tourers (GTs), and purpose-built sports prototype cars compete within their respective classes on closed circuits. The premier championship series of sports car racing is the FIA World Endurance Championship. The main series for GT car racing is the Blancpain GT Series, divided into two separate championships: the Blancpain GT World Challenge Europe and the Blancpain GT Series Endurance Cup. This series has formed after the folding of the various FIA GT championships. Other major GT championships include the Blancpain GT World Challenge America, Blancpain GT World Challenge Asia, Super GT, and the International GT Open. There are minor regional and national GT series using mainly GT4 and GT3 cars featuring both amateur and professional drivers. Sports prototypes, unlike GT cars, do not rely on road-legal cars as a base. They are closed-wheel and often closed-cockpit purpose-built race cars intended mainly for endurance racing. They have much lower weight and more downforce compared to GT cars, making them much faster. They are raced in the 24 hours of Le Mans (held annually since 1923) and in the (European) Le Mans series, Asian Le Mans Series and the WeatherTech SportsCar Championship. These cars are referred to as LMP (Le Mans prototype) cars with LMP1 being run mainly by manufacturers and the slightly less powerful LMP2 cars run by privateer teams. All three Le Mans Series run GT cars in addition to Le Mans Prototypes; these cars have different restrictions than the FIA GT cars. Another prototype and GT racing championship exists in the United States; the Grand-Am, which began in 2000, sanctions its own endurance series, the Rolex Sports Car Series, which consists of slower and lower-cost race cars compared to LMP and FIA GT cars. The Rolex Sports Car Series and American Le Mans Series announced a merger between the two series forming the WeatherTech SportsCar Championship starting in 2014. These races are often conducted over long distances, at least , and cars are driven by teams of two or more drivers, switching every few hours. Due to the performance difference between production-based sports cars and purpose-built sports prototypes, one race usually involves several racing classes, each fighting for its own championship. Famous sports car races include the 24 Hours of Le Mans, the Rolex 24 at Daytona, 24 Hours of Spa-Franchorchamps, the 12 Hours of Sebring, the 6 Hours of Watkins Glen, and the Petit Le Mans at Road Atlanta. There is also the 24 Hours of the Nürburgring on the infamous Nordschleife track and the Dubai 24 Hour, which is aimed at GT3 and below cars with a mixture of professional and pro-am drivers. Production-car racing Production-car racing, otherwise known as "showroom stock" in the US, is an economical and rules-restricted version of touring-car racing, mainly used to restrict costs. Numerous production racing categories are based on particular makes of cars. Most series, with a few exceptions, follow the Group N regulation. There are several different series that are run all over the world, most notably, Japan's Super Taikyu and IMSA's Firehawk Series, which ran in the 1980s and 1990s all over the United States. Stock car racing In North America, stock car racing is the most popular form of auto racing. Primarily raced on oval tracks, stock cars vaguely resemble production cars, but are in fact purpose-built racing machines that are built to tight specifications and, together with touring cars, also called Silhouette racing cars. The largest stock car racing governing body is NASCAR (National Association for Stock Car Auto Racing). NASCAR's premier series is the NASCAR Cup Series, its most famous races being the Daytona 500, the Southern 500, the Coca-Cola 600, and the Brickyard 400. NASCAR also runs several feeder series, including the Xfinity Series and Gander RV & Outdoors Truck Series (a pickup truck racing series). The series conduct races across the entire continental United States. The NASCAR Pinty's Series conducts races across Canada and the NASCAR PEAK Mexico Series conducts races across Mexico. NASCAR also governs several smaller regional series, such as the Whelen Modified Tour. Modified cars are best described as open-wheel cars. Modified cars have no parts related to the stock vehicle for which they are named after. A number of modified cars display a "manufacturer's" logo and "vehicle name", yet use components produced by another automobile manufacturer. There are also other stock car governing bodies, most notably the Automobile Racing Club of America (ARCA). In the UK, British Stock car racing is also referred to as "Short Circuit Racing". UK Stock car racing started in the 1950s and grew rapidly through the 1960s and 1970s. Events take place on shale or tarmac tracks – usually around 1/4 mile long. There are around 35 tracks in the UK and upwards of 7000 active drivers. The sport is split into three basic divisions – distinguished by the rules regarding car contact during racing. The most famous championship are the BriSCA F1 Stock Cars. Full-contact formulas include Bangers, Bombers, and Rookie Bangers – and racing features Demolition Derbies, Figure of Eight, and Oval Racing. Semi Contact Formulas include BriSCA F1, F2, and Superstox – where bumpers are used tactically. Non-contact formulas include National Hot Rods, Stock Rods, and Lightning Rods. One-make racing One-make, or single marque, championships often employ production-based cars from a single manufacturer or even a single model from a manufacturer's range. There are numerous notable one-make formulae from various countries and regions, some of which – such as the Porsche Supercup and, previously, IROC – have fostered many distinct national championships. Single marque series are often found at the club level, to which the production-based cars, limited modifications, and close parity in performance are very well suited. Some of the better-known single-make series are the Mini 7 Championship (Europe's longest-running one-make championship), the Radical European Masters, John Cooper Mini Challenge, Clio Cup, Ginettas, Caterhams, BMWs, and MX5s. There are also single-chassis single seater formulae, such as Formula Renault and Formula BMW, usually as "feeder" series for "senior" race formula (in the fashion of farm teams). Rallying Rallying is typically distinguished from other forms of motorsport by not running directly against other competitors over laps of a circuit, but instead in a point-to-point format in which participants leave at regular intervals from one or more start points. Cars compete on closed public roads or off-road areas on a point-to-point format where participants and their co-drivers "rally" to a set of points, leaving in regular intervals from start points. A rally is typically conducted over a number of "special stages" on any terrain, which entrants are often allowed to scout beforehand at reduced speeds compiling detailed shorthand descriptions of the track or road as they go. These detailed descriptions are known as pace notes. During the actual rally, the co-driver reads the pace notes aloud (using an in-helmet intercom system) to the driver, enabling them to complete each stage as quickly as possible. Competition is based on the lowest total elapsed time over the course of an event's special stages, including penalties. Rallying at international and most national championship levels involves two classes of homologated road-legal production-based cars; Group N production cars and more modified Group A cars. The top series is the World Rally Championship (WRC), first contested in 1973, but there are also regional championships, and many countries have their own national championships. Some famous rallies include the Monte Carlo Rally, Rally Argentina, Rally Finland, and Rally GB. Another famous event (actually best described as a rally raid) is the Paris-Dakar Rally, conceived in 1978. There are also many smaller, club level, categories of rallies, which are popular with amateurs, making up the "grass roots" of motor sports. Cars at this level may not comply fully with the requirements of group A or group N homologation. Other major rally events include the British Rally Championship, Intercontinental Rally Challenge, African Rally Championship, Asia-Pacific Rally Championship, and endurance rally events like the Dakar Rally. The Targa Tasmania, held on the Australian island state of Tasmania and run annually since 1992, takes its name from the Targa Florio, a former motoring event held on the island of Sicily. The competition concept is drawn directly from the best features of the Mille Miglia, the Coupe des Alpes, and the Tour de Corse. Similarly named events around the world include the Targa Newfoundland based in Canada, Targa West based in Western Australia, Targa New Zealand, and other smaller events. Time Attack Series Time attack events began in Japan in the mid-1960s. They have since spread around the world. Time Attack racing is a type of motorsport in which the racers compete for the best lap time. Each vehicle is timed through numerous circuits of the track. The racers make a preliminary circuit, then run the timed laps, and then finish with a cool-down lap. Time Attack and time trial events differ by competition format and rules. Time Attack has a limited number of laps, time trial has open sessions. Unlike other timed motorsport disciplines such as sprinting and hillclimbing, the car is required to start off under full rolling start conditions following a warm-up lap in which they will have to accelerate out as fast as possible to determine how fast they enter their timed lap. Commonly, as the cars are modified road-going cars, they are required to have tires authorized for road use. Drag racing In drag racing, the objective is to complete a given straight-line distance, from a standing start, ahead of a vehicle in a parallel lane. This distance is traditionally , though has become popular since the 1990s. The vehicles may or may not be given the signal to start at the same time, depending on the class of racing. Vehicles range from the everyday car to the purpose-built dragster. Speeds and elapsed time differ from class to class. Average street cars cover the mile in 12 to 16 seconds, whereas a top fuel dragster takes 4.5 seconds or less, reaching speeds of up to . Drag racing was organized as a sport by Wally Parks in the early 1950s through the National Hot Rod Association (NHRA). The NHRA was formed to discourage street racing. When launching, a top fuel dragster will accelerate at 3.4 g (33 m/s2), and when braking parachutes are deployed the deceleration is 4 g (39 m/s2), more than the Space Shuttle experiences. A top fuel car can be heard over away and can generate a reading from 1.5 to 3.9 on the Richter scale. Drag racing is two cars head-to-head, the winner proceeding to the next round. Professional classes are all first to the finish line wins. Sportsman racing is handicapped (slower car getting a head start) using an index (a lowest e.t. allowed), and cars running under (quicker than) their index "break out" and lose. The slowest cars, bracket racers, are also handicapped, but rather than an index, they use a dial-in. Off-road racing In off-road racing, various classes of specially modified vehicles, including cars, compete in races through off-road environments. In North America these races often take place in the desert, such as the famous Baja 1000. Another format for off-road racing happens on closed-course short course tracks such as Crandon International Off-Road Raceway. In the 1980s and 1990s, the short course was extended to racing inside stadiums in the Mickey Thompson Entertainment Group; this format was revived by Robby Gordon in 2013 with his Stadium Super Trucks series. In Europe, "offroad" refers to events such as autocross or rallycross, while desert races and rally-raids such as the Paris-Dakar, Master Rallye or European "bajas" are called "cross-country rallies." Kart racing The modern kart was invented by Art Ingels, a fabricator at the Indianapolis-car manufacturer Kurtis-Kraft, in Southern California in 1956. Ingels took a small chainsaw engine and mounted it to a simple tube-frame chassis weighing less than 100 lb. Ingels, and everyone else who drove the kart, were startled at its performance capabilities. The sport soon blossomed in Southern California, and quickly spread around the world. Although often seen as the entry point for serious racers into the sport, kart racing, or karting, can be an economical way for amateurs to try racing and is also a fully-fledged international sport in its own right. A large proportion of professional racing drivers began in karts, often from a very young age, such as Michael Schumacher and Fernando Alonso. Several former motorcycle champions have also taken up the sport, notably Wayne Rainey, who was paralysed in a racing accident and now races a hand-controlled kart. As one of the cheapest ways to race, karting is seeing its popularity grow worldwide. Despite their diminutive size, karts of the most powerful class, superkart (assuming a weight of 205 kg (452 lb), and a power output of 100 hp (75 kW)), can have a power-to-weight ratio (including the driver) of 490 hp/tonne (0.22 hp/lb). Without the driver, this figure doubles, to almost 980 hp/tonne (0.44 hp/lb). Historical racing Historic motorsport or vintage motorsport uses vehicles limited to a particular era. Only safety precautions are modernized in these hobbyist races. A historical event can be of various types of motorsport disciplines, from road racing to rallying. Because it is based on a particular era it is more hobbyist-oriented, reducing corporate sponsorship. The only modern equipment used is related to safety and timing. A historical event can be of a number of different motorsport disciplines. Some of the most famous events include the Goodwood Festival of Speed and Goodwood Revival in Britain and Monterey Historic in the United States. Championships range from "grass root" Austin Seven racing to the FIA Thoroughbred Grand Prix Championship for classic Formula One chassis. While there are several professional teams and drivers in historical racing, this branch of auto sport tends to be contested by wealthy car owners and is thus more amateur and less competitive in its approach. Other categories Use of flags In many types of auto races, particularly those held on closed courses, flags are displayed to indicate the general status of the track and to communicate instructions to competitors. While individual series have different rules, and the flags have changed from the first years (e.g., red used to start a race), these are generally accepted. Accidents The worst accident in racing history is the 1955 Le Mans disaster, where more than 80 people died, including the French driver Pierre Levegh. Racing-car setup In auto racing, the racing setup or car setup is the set of adjustments made to the vehicle to optimize its behaviour (performance, handling, reliability, etc.). Adjustments can occur in suspensions, brakes, transmissions, engines, tires, and many others. Aerodynamics Aerodynamics and airflow play big roles in the setup of a race car. Aerodynamic downforce improves the race car's handling by lowering the center of gravity and distributing the weight of the car equally on each tire. Once this is achieved, fuel consumption decreases and the forces against the car are significantly lowered. Many aerodynamic experiments are conducted in wind tunnels, to simulate real-life situations while measuring the various drag forces on the car. These "Rolling roads" produce many wind situations and direct air flow at certain speeds and angles. When a diffuser is installed under the car, the amount of drag force is significantly lowered, and the overall aerodynamics of the vehicle is positively adjusted. Wings and canards channel the airflow in the most efficient way to get the least amount of drag from the car. It is experimentally proven that downforce is gained and the vehicle's handling is considerably changed when aerodynamic wings on the front and rear of the vehicle are installed. Suspension Suspension plays a huge part in giving the race car the ability to be driven optimally. Shocks are mounted vertically or horizontally to prevent the body from rolling in the corners. The suspension is important because it makes the car stable and easier to control and keeps the tires on the road when driving on uneven terrain. It works in three different ways including vertically, longitudinally, and laterally to control movement when racing on various tracks. Tyres Tyres called R-Compounds are commonly used in motorsports for high amounts of traction. The soft rubber allows them to expand when they are heated up, making more surface area on the pavement, therefore producing the most traction. These types of tyres do not have grooves on them. Tyre pressure is dependent on the temperature of the tyre and track when racing. Each time a driver pulls into the pits, the tyre pressure and temperature should be tested for optimal performance. When the tyres get too hot they will swell or inflate and need to be deflated to the correct pressure. When the tyres are not warmed up they will not perform as well. Brakes Brakes on a race car are imperative in slowing and stopping the car at precise times and wear quickly depending on the road or track on which the car is being raced, how many laps are being run, track conditions due to weather, and how many caution runs require more braking. There are three variables to consider in racing: brake pedal displacement, brake pedal force, and vehicle deceleration. Various combinations of these variables work together to determine the stiffness, sensitivity, and pedal force of the brakes. When using the brakes effectively, the driver must go through a buildup phase and end with a modulating phase. These phases include attaining maximum deceleration and modulating the brake pressure. Brake performance is measured in bite and consistency. Bite happens when the driver first applies the brakes and they have not warmed up to the correct temperature to operate efficiently. Consistency is measured in how consistent the friction is during the entire time of braking. These two measurements determine the wear of the brakes. Engine The race car's engine needs a considerable amount of air to produce maximum power. The air intake manifold sucks the air from scoops on the hood and front bumper and feeds it into the engine. Many engine modifications to increase horsepower and efficiency are commonly used in many racing-sanctioning bodies. Engines are tuned on a machine called a dynamometer, which is commonly known in the racing world as a DYNO. The car is driven onto the DYNO and many gauges and sensors are hooked up to the car that are controlled by an online program to test force, torque, or power. Through the testing, the car's engine maps can be changed to get the most horsepower and ultimately speed out of the vehicle. Racing driver Racing drivers, at the highest levels, are usually paid by the team, or by sponsors, and can command very substantial salaries. Contrary to what may be popularly assumed, racing drivers as a group do not have unusually better reflexes or peripheral response time. During repeated physiological (and psychological) evaluations of professional racing drivers, the two characteristics that stand out are racers' near-obsessive need to control their surroundings (the psychological aspect), and an unusual ability to process fast-moving information (physiological). In this, researchers have noted a strong correlation between racers' psychological profiles and those of fighter pilots. In tests comparing racers to members of the general public, the greater the complexity of the information processing matrix, the greater the speed gap between racers and the public. Due partly to the performance capabilities of modern racing cars, racing drivers require a high level of fitness, focus, and the ability to concentrate at high levels for long periods in an inherently difficult environment. Racing drivers mainly complain about pains in the lumbar, shoulder, and neck regions. Racing drivers experience extremely large g-forces because formula cars and sports prototypes generate more downforce and are able to corner at significantly higher speeds. Formula 1 drivers routinely experience g-loadings in excess of 4.5 g.

Ancient philosophy

This page lists some links to ancient philosophy, namely philosophical thought extending as far as early post-classical history (). Overview Genuine philosophical thought, depending upon original individual insights, arose in many cultures roughly contemporaneously. Karl Jaspers termed the intense period of philosophical development beginning around the 7th century BCE and concluding around the 3rd century BCE an Axial Age in human thought. In Western philosophy, the spread of Christianity in the Roman Empire marked the ending of Hellenistic philosophy and ushered in the beginnings of medieval philosophy, whereas in the Middle East, the spread of Islam through the Arab Empire marked the end of Old Iranian philosophy and ushered in the beginnings of early Islamic philosophy.

The first charter of human rights by Cyrus the Great as understood in the Cyrus cylinder is often seen as a reflection of the questions and thoughts expressed by Zarathustra and developed in Zoroastrian schools of thought of the Achaemenid Era of Iranian history. Schools of thought Ideas and tenets of Zoroastrian schools of Early Persian philosophy are part of many works written in Middle Persian and of the extant scriptures of the zoroastrian religion in Avestan language. Among these are treatises such as the Shikand-gumanic Vichar by Mardan-Farrux Ohrmazddadan, selections of Denkard, Wizidagīhā-ī Zātspram ("Selections of Zātspram") as well as older passages of the book Avesta, the Gathas which are attributed to Zarathustra himself and regarded as his "direct teachings".

Vedic philosophy Indian philosophy begins with the Vedas wherein questions pertaining to laws of nature, the origin of the universe and the place of man in it are asked. In the famous Rigvedic Hymn of Creation (Nasadiya Sukta) the poet asks: "Whence all creation had its origin, he, whether he fashioned it or whether he did not, he, who surveys it all from highest heaven, he knows—or maybe even he does not know." In the Vedic view, creation is ascribed to the self-consciousness of the primeval being (Purusha). This leads to the inquiry into the one being that underlies the diversity of empirical phenomena and the origin of all things. Cosmic order is termed rta and causal law by karma. Nature (prakriti) is taken to have three qualities (sattva, rajas, and tamas). Vedas Upanishads Hindu philosophy Sramana philosophy Jainism and Buddhism are continuation of the Sramana school of thought. The Sramanas cultivated a pessimistic worldview of the samsara as full of suffering and advocated renunciation and austerities. They laid stress on philosophical concepts like Ahimsa, Karma, Jnana, Samsara and Moksa. Cārvāka (Sanskrit: चार्वाक) (atheist) philosophy, also known as Lokāyata, it is a system of Hindu philosophy that assumes various forms of philosophical skepticism and religious indifference. It is named after its founder, Cārvāka, author of the Bārhaspatya-sūtras. Classical Indian philosophy In classical times, these inquiries were systematized in six schools of philosophy. Some of the questions asked were: What is the ontological nature of consciousness? How is cognition itself experienced? Is mind (chit) intentional or not? Does cognition have its own structure? The six schools of Indian philosophy are: Nyaya Vaisheshika Samkhya Yoga Mimamsa (Purva Mimamsa) Vedanta (Uttara Mimamsa) Ancient Indian philosophers 1st millennium BCE Parashara – writer of Viṣṇu Purāṇa.

Adi Shankara – philosopher and theologian, most renowned exponent of the Advaita Vedanta school of philosophy. Ancient Chinese philosophy Chinese philosophy is the dominant philosophical thought in China and other countries within the East Asian cultural sphere that share a common language, including Japan, Korea, and Vietnam. Schools of thought Hundred Schools of Thought The Hundred Schools of Thought were philosophers and schools that flourished from the 6th century to 221 BCE, an era of great cultural and intellectual expansion in China. Even though this period – known in its earlier part as the Spring and Autumn period and the Warring States period – in its latter part was fraught with chaos and bloody battles, it is also known as the Golden Age of Chinese philosophy because a broad range of thoughts and ideas were developed and discussed freely. The thoughts and ideas discussed and refined during this period have profoundly influenced lifestyles and social consciousness up to the present day in East Asian countries. The intellectual society of this era was characterized by itinerant scholars, who were often employed by various state rulers as advisers on the methods of government, war, and diplomacy. This period ended with the rise of the Qin Dynasty and the subsequent purge of dissent. The Book of Han lists ten major schools, they are: Confucianism, which teaches that human beings are teachable, improvable and perfectible through personal and communal endeavour especially including self-cultivation and self-creation. A main idea of Confucianism is the cultivation of virtue and the development of moral perfection. Confucianism holds that one should give up one's life, if necessary, either passively or actively, for the sake of upholding the cardinal moral values of ren and yi. Legalism. Often compared with Machiavelli, and foundational for the traditional Chinese bureaucratic empire, the Legalists examined administrative methods, emphasizing a realistic consolidation of the wealth and power of autocrat and state. Taoism (also called Daoism), a philosophy which emphasizes the Three Jewels of the Tao: compassion, moderation, and humility, while Taoist thought generally focuses on nature, the relationship between humanity and the cosmos; health and longevity; and wu wei (action through inaction). Harmony with the Universe, or the source thereof (Tao), is the intended result of many Taoist rules and practices. Mohism, which advocated the idea of universal love: Mozi believed that "everyone is equal before heaven", and that people should seek to imitate heaven by engaging in the practice of collective love. His epistemology can be regarded as primitive materialist empiricism; he believed that human cognition ought to be based on one's perceptions – one's sensory experiences, such as sight and hearing – instead of imagination or internal logic, elements founded on the human capacity for abstraction. Mozi advocated frugality, condemning the Confucian emphasis on ritual and music, which he denounced as extravagant. Naturalism, the School of Naturalists or the Yin-yang school, which synthesized the concepts of yin and yang and the Five Elements; Zou Yan is considered the founder of this school. Agrarianism, or the School of Agrarianism, which advocated peasant utopian communalism and egalitarianism. The Agrarians believed that Chinese society should be modeled around that of the early sage king Shen Nong, a folk hero which was portrayed in Chinese literature as "working in the fields, along with everyone else, and consulting with everyone else when any decision had to be reached." The Logicians or the School of Names, which focused on definition and logic. It is said to have parallels with that of the Ancient Greek sophists or dialecticians. The most notable Logician was Gongsun Longzi. The School of Diplomacy or School of Vertical and Horizontal [Alliances], which focused on practical matters instead of any moral principle, so it stressed political and diplomatic tactics, and debate and lobbying skill. Scholars from this school were good orators, debaters and tacticians. The Miscellaneous School, which integrated teachings from different schools; for instance, Lü Buwei found scholars from different schools to write a book called Lüshi Chunqiu cooperatively. This school tried to integrate the merits of various schools and avoid their perceived flaws. The School of "Minor-talks", which was not a unique school of thought, but a philosophy constructed of all the thoughts which were discussed by and originated from normal people on the street. Another group is the School of the Military that studied strategy and the philosophy of war; Sunzi and Sun Bin were influential leaders. However, this school was not one of the "Ten Schools" defined by Hanshu. Early Imperial China The founder of the Qin Dynasty, who implemented Legalism as the official philosophy, quashed Mohist and Confucianist schools. Legalism remained influential until the emperors of the Han Dynasty adopted Daoism and later Confucianism as official doctrine. These latter two became the determining forces of Chinese thought until the introduction of Buddhism. Confucianism was particularly strong during the Han Dynasty, whose greatest thinker was Dong Zhongshu, who integrated Confucianism with the thoughts of the Zhongshu School and the theory of the Five Elements. He also was a promoter of the New Text school, which considered Confucius as a divine figure and a spiritual ruler of China, who foresaw and started the evolution of the world towards the Universal Peace. In contrast, there was an Old Text school that advocated the use of Confucian works written in ancient language (from this comes the denomination Old Text) that were so much more reliable. In particular, they refuted the assumption of Confucius as a godlike figure and considered him as the greatest sage, but simply a human and mortal. The 3rd and 4th centuries saw the rise of the Xuanxue (mysterious learning), also called Neo-Taoism. The most important philosophers of this movement were Wang Bi, Xiang Xiu and Guo Xiang. The main question of this school was whether Being came before Not-Being (in Chinese, ming and wuming). A peculiar feature of these Taoist thinkers, like the Seven Sages of the Bamboo Grove, was the concept of feng liu (lit. wind and flow), a sort of romantic spirit which encouraged following the natural and instinctive impulse. Buddhism arrived in China around the 1st century AD, but it was not until the Northern and Southern, Sui and Tang Dynasties that it gained considerable influence and acknowledgement. At the beginning, it was considered a sort of Taoist sect, and there was even a theory about Laozi, founder of Taoism, who went to India and taught his philosophy to Buddha. Mahayana Buddhism was far more successful in China than its rival Hinayana, and both Indian schools and local Chinese sects arose from the 5th century. Two chiefly important monk philosophers were Sengzhao and Daosheng. But probably the most influential and original of these schools was the Chan sect, which had an even stronger impact in Japan as the Zen sect.

Amber Diceless Roleplaying Game

The Amber Diceless Roleplaying Game is a role-playing game created and written by Erick Wujcik, set in the fictional universe created by author Roger Zelazny for his Chronicles of Amber. The game is unusual in that no dice are used in resolving conflicts or player actions; instead a simple diceless system of comparative ability, and narrative description of the action by the players and gamemaster, is used to determine how situations are resolved. Amber DRPG was created in the 1980s, and is much more focused on relationships and roleplaying than most of the roleplaying games of that era. Most Amber characters are members of the two ruling classes in the Amber multiverse, and are much more advanced in matters of strength, endurance, psyche, warfare and sorcery than ordinary beings. This often means that the only individuals who are capable of opposing a character are from his or her family, a fact that leads to much suspicion and intrigue. History Erick Wujcik wanted to design a role-playing game based on Amber for West End Games, and they agreed to look at his work. Wujcik intended to integrate the feel of the Amber setting from the novels into a role-playing game, and playtested his system for a few months at the Michigan Gaming Center where he decided to try it out as a diceless game. West End Games was not interested in a diceless role-playing game, so Wujcik acquired the role-playing game rights to Amber and offered the game to R. Talsorian Games, until he withdrew over creative differences. Wujcik then founded Phage Press, and published Amber Diceless Role-playing in 1991. The original 256-page game book was published in 1991 by Phage Press, covering material from the first five novels (the "Corwin Cycle") and some details – sorcery and the Logrus – from the remaining five novels (the "Merlin Cycle"), in order to allow players to roleplay characters from the Courts of Chaos. Some details were changed slightly to allow more player choice – for example, players can be full Trump Artists without having walked the Pattern or the Logrus, which Merlin says is impossible; and players' psychic abilities are far greater than those shown in the books. A 256-page companion volume, Shadow Knight, was published in 1993. This supplemental rule book includes the remaining elements from the Merlin novels, such as Broken Patterns, and allows players to create Constructs such as Merlin's Ghostwheel. The book presents the second series of novels not as additions to the series' continuity but as an example of a roleplaying campaign with Merlin, Luke, Julia, Jurt and Coral as the PCs. The remainder of the book is a collection of essays on the game, statistics for the new characters and an update of the older ones in light of their appearance in the second series, and (perhaps most usefully for GMs) plot summaries of each of the ten books. The book includes some material from the short story "The Salesman's Tale," and some unpublished material cut from Prince of Chaos, notably Coral's pregnancy by Merlin. Both books were translated into French and published by Jeux Descartes in 1994 and 1995. A third book, Rebma, was promised. Cover art was commissioned and pre-orders were taken, but it was never published. Wujcik also expressed a desire to create a book giving greater detail to the Courts of Chaos. The publishing rights to the Amber DRPG games were acquired in 2004 by Guardians of Order, who took over sales of the game and announced their intention to release a new edition of the game. However, no new edition was released before Guardians of Order went out of business in 2006. The two existing books are now out-of-print, but they have been made available as PDF downloads. In June 2007 a new publishing company, headed by Edwin Voskamp and Eric Todd, was formed with the express purpose of bringing Amber DRPG back into print. The new company is named Diceless by Design. In May 2010, Rite Publishing secured a license from Diceless by Design to use the rules system with a new setting in the creation of a new product to be written by industry and system veteran Jason Durall. The project Lords of Gossamer & Shadow (Diceless) was funded via Kickstarter in May 2013. In Sept 2013 the project was completed, and on in Nov 2013 Lords of Gossamer and Shadow (Diceless) was released publicly in full-color Print and PDF, along with additional supplements and continued support. Setting The game is set in the multiverse described in Zelazny's Chronicles of Amber. The first book assumes that gamemasters will set their campaigns after the Patternfall war; that is, after the end of the fifth book in the series, The Courts of Chaos, but uses material from the following books to describe those parts of Zelazny's cosmology that were featured there in more detail. The Amber multiverse consists of Amber, a city at one pole of the universe wherein is found the Pattern, the symbol of Order; The Courts of Chaos, an assembly of worlds at the other pole where can be found the Logrus, the manifestation of Chaos, and the Abyss, the source or end of all reality; and Shadow, the collection of all possible universes (shadows) between and around them. Inhabitants of either pole can use one or both of the Pattern and the Logrus to travel through Shadow. It is assumed that players will portray the children of the main characters from the books – the ruling family of Amber, known as the Elder Amberites – or a resident of the Courts. However, since some feel that being the children of the main characters is too limiting, it is fairly common to either start with King Oberon's death before the book begins and roleplay the Elder Amberites as they vie for the throne; or to populate Amber from scratch with a different set of Elder Amberites. The former option is one presented in the book; the latter is known in the Amber community as an "Amethyst" game. A third option is to have the players portray Corwin's children, in an Amber-like city built around Corwin's pattern; this is sometimes called an "Argent" game, since one of Corwin's heraldic colours is Silver. System Attributes Characters in Amber DRPG are represented by four attributes: Psyche, Strength, Endurance and Warfare. Psyche is used for feats of willpower or magic Strength is used for feats of strength or unarmed combat Endurance is used for feats of endurance Warfare is used for armed combat, from duelling to commanding armies The attributes run from −25 (normal human level), through −10 (normal level for a denizen of the Courts of Chaos) and 0 (normal level for an inhabitant of Amber), upwards without limit. Scores above 0 are "ranked", with the highest score being ranked 1st, the next-highest 2nd, and so on. The character with 1st rank in each attribute is considered "superior" in that attribute, being considered to be substantially better than the character with 2nd rank even if the difference in scores is small. All else being equal, a character with a higher rank in an attribute will always win a contest based on that attribute. The Attribute Auction A character's ability scores are purchased during character creation in an auction; players get 100 character points, and bid on each attribute in turn. The character who bids the most for an attribute is "ranked" first and is considered superior to all other characters in that attribute. Unlike conventional auctions, bids are non-refundable; if one player bids 65 for psyche and another wins with a bid of 66, then the character with 66 is "superior" to the character with 65 even though there is only one bid difference. Instead, lower bidding characters are ranked in ascending order according to how much they have bid, the characters becoming progressively weaker in that attribute as they pay less for it. After the auction, players can secretly pay extra points to raise their ranks, but they can only pay to raise their scores to an existing rank. Further, a character with a bid-for rank is considered to have a slight advantage over character with a bought-up rank. The Auction simulates a 'history' of competition between the descendants of Oberon for player characters who have not had dozens of decades to get to know each other. Through the competitive Auction, characters may begin the game vying for standings. The auction serves to introduce some unpredictability into character creation without the need to resort to dice, cards, or other randomizing devices. A player may intend, for example, to create a character who is a strong, mighty warrior, but being "outplayed" in the auction may result in lower attribute scores than anticipated, therefore necessitating a change of character concept. Since a player cannot control another player's bids, and since all bids are non-refundable, the auction involves a considerable amount of strategizing and prioritization by players. A willingness to spend as many points as possible on an attribute may improve your chances of a high ranking, but too reckless a spending strategy could leave a player with few points to spend on powers and objects. In a hotly contested auction, such as for the important attribute of warfare, the most valuable skill is the ability to force one's opponents to back down. With two or more equally determined players, this can result in a "bidding war," in which the attribute is driven up by increments to large sums. An alternative strategy is to try to cow other players into submission with a high opening bid. Most players bid low amounts between one and ten points in an initial bid in order to feel out the competition and to save points for other uses. A high enough opening bid could signal a player's determination to be first ranked in that attribute, thereby dissuading others from competing. Psyche in Amber DRPG compared to the Chronicles Characters with high psyche are presented as having strong telepathic abilities, being able to hypnotise and even mentally dominate any character with lesser psyche with whom they can make eye-contact. This is likely due to three scenes in the Chronicles: first, when Eric paralyzes Corwin with an attack across the Trump and refuses to desist because one or the other would be dominated; second, when Corwin faces the demon Strygalldwir, it is able to wrestle mentally with him when their gazes meet; and third, when Fiona is able to keep Brand immobile in the final battle at the Courts of Chaos. However, in general, the books only feature mental battles when there is some reason for mind-to-mind contact (for example, Trump contact) and magic or Trump is involved in all three of the above conflicts, so it is not clear whether Zelazny intended his characters to have such a power; the combination of Brand's "living trump" powers and his high Psyche (as presented in the roleplaying game) would have guaranteed him victory over Corwin. Shadow Knight does address this inconsistency somewhat, by presenting the "living trump" abilities as somewhat limited. Powers Characters in Amber DRPG have access to the powers seen in the Chronicles of Amber: Pattern, Logrus, Shape-shifting, Trump, and magic. Pattern: A character who has walked the pattern can walk in shadow to any possible universe, and while there can manipulate probability. Logrus: A character who has mastered the Logrus can send out Logrus tendrils and pull themselves or objects through shadow. Shape-shifting: Shape-shifters can alter their physical form and abilities. Trump: Trump Artists can create Trumps, a sort of tarot card which allows mental communication and travel. The book features Trump portraits of each of the elder Amberites. The trump picture of Corwin is executed in a subtly different style – and has features very similar to Roger Zelazny's. Magic: Three types of magic are detailed: Power Words, with a quick, small effect; Sorcery, with pre-prepared spells as in many other game systems; and Conjuration, the creation of small objects. Each of the first four powers is available in an advanced form. Artifacts, Personal shadows and Constructs While a character with Pattern, Logrus or Conjuration can acquire virtually any object, players can choose to spend character points to obtain objects with particular virtues – unbreakability, or a mind of their own. Since they have paid points for the items, they are a part of the character's legend, and cannot lightly be destroyed. Similarly, a character can find any possible universe, but they can spend character points to know of or inhabit shadows which are (in some sense) "real" and therefore useful. The expansion, Shadow Knight, adds Constructs – artifacts with connections to shadows. Stuff Unspent character points become good stuff – a good luck for the character. Players are also allowed to overspend (in moderation), with the points becoming bad stuff – bad luck which the Gamemaster should inflict on the character. Stuff governs how non-player characters perceive and respond to the character: characters with good stuff will often receive friendly or helpful reactions, while characters with bad stuff are often treated with suspicion or hostility. As well as representing luck, stuff can be seen as representing a character's outlook on the universe: characters with good stuff seeing the multiverse as a cheerful place, while characters with bad stuff see it as hostile. Conflict resolution In any given fair conflict between two characters, the character with the higher score in the relevant attribute will eventually win. The key words here are fair and eventually – if characters' ranks are close, and the weaker character has obtained some advantage, then the weaker character can escape defeat or perhaps prevail. Close ranks result in longer contests while greater difference between ranks result in fast resolution. Alternatively, if characters' attribute ranks are close, the weaker character can try to change the relevant attribute by changing the nature of the conflict. For example, if two characters are wrestling the relevant attribute is Strength; a character could reveal a weapon, changing it to Warfare; they could try to overcome the other character's mind using a power, changing it to Psyche; or they could concentrate their strength on defense, changing it to Endurance. If there is a substantial difference between characters' ranks, the conflict is generally over before the weaker character can react. The "Golden Rule" Amber DRPG advises gamemasters to change rules as they see fit, even to the point of adding or removing powers or attributes. Reception In the June 1992 edition of Dragon (Issue 182), both Lester Smith and Allen Varney published reviews of this game. Smith admired the professional production qualities of the 256-page rulebook, noting that because it was Smyth sewn in 32-page signatures, the book would always lie flat when opened. However, he found the typeface difficult to read, and the lack a coherent hierarchy of rules increased the reading difficulty as well. Smith admired the Attribute Auction and point-buy system for skills, and the focus on roleplaying in place of dice-rolling, but he mused that all of the roleplaying would mean "GMs have to spend quite a bit of time and creative effort coming up with wide-reaching plots for their players to work through. Canned, linear adventures just won't serve." He concluded by stating that the diceless system is not for every gamer: "As impressed as I am with the game, do I think it is the 'end-all' of role-playing games, or that diceless systems are the wave of the future? I'll give a firm “No” on both counts... However, I certainly do think that the Amber Diceless Roleplaying Game is destined for great popularity and a niche among the most respected of role-playing game designs." Allen Varney thought the "Attribute Auction" to be "brilliant and elegant", but he wondered if character advancement was perhaps too slow to keep marginal players interested. He also believed that being a gamemaster would be "tough work. Proceed with caution." Varney recommended that players need some familiarity with the first five "Amber" novels by Zelazny. He concluded, "The intensity of the Amber game indicates [game designer Erik ] Wujcik is on to something. When success in every action depends on the role and not the roll, players develop a sense of both control and urgency, along with creativity that borders on mania." In Issue 65 of Challenge, Dirk DeJong had a good first impression of the game, especially the information provided about the Amber family members and their various flaws and strengths. However he found that "The biggest problem with this endeavor, and its downfall, is the nature of the conflict systems. First, they are diceless, really diceless, and don't involve any sort of random factors at all, aside from those that you can introduce by roleplaying them out. Thus, if you get involved with a character who's better than you at sword-fighting, even if only by one point out of 100, you're pretty much dead meat, unless you can act your way out." DeJong also disagreed with the suggestion that if the referee and players disagreed with a rule to simply remove it from the game. "I thought the entire idea of using rules and random results was to prevent the type of arguments that I can see arising from this setup." DeJong concluded on an ambivalent note, saying, "If you love Zelazny and the Amber series, jump on it, as this is the premier sourcebook for running an Amber campaign. [...] Personally, I just can't get turned on by a system that expects me to either be content with a simple subtraction of numbers to find out who won, or to describe an entire combat blow by blow, just so that I can attempt some trick to win." Loyd Blankenship reviewed Amber in Pyramid #2 (July/Aug., 1993), and stated that "Amber is a valuable resource to a GM - even if he isn't running an Amber game. For gamers who have an aspiring actor or actress lurking within their breast, or for someone running a campaign via electronic mail or message base, Amber should be given serious consideration." Other reviews and commentary White Wolf #31 (May/June, 1992) Shadis #10 (Dec., 1993) Casus Belli #70 (July 1992) Community Despite the game's out-of-print status, a thriving convention scene exists supporting the game. Amber conventions, known as Ambercons, are held yearly in Massachusetts, Michigan, Portland (United States), Milton Keynes (England), Belfast (Northern Ireland) and Modena, Italy. Additionally, Phage Press published 12 volumes of a dedicated Amber DRPG magazine called Amberzine. Some Amberzine issues are still available from Phage Press.

https://en.wikipedia.org/wiki/Artistic%20revolution

Artistic revolution

Throughout history, forms of art have gone through periodic abrupt changes called artistic revolutions. Movements have come to an end to be replaced by a new movement markedly different in striking ways. Scientific and technological Not all artistic revolutions were political. Sometimes, science and technological innovations have brought about unforeseen transformations in the works of artists. The stylistic revolution known as Impressionism, by painters eager to more accurately capture the changing colors of light and shadow, is inseparable from discoveries and inventions in the mid-19th century in which the style was born. Michel Eugène Chevreul, a French chemist hired as director of dyes at a French tapestry works, began to investigate the optical nature of color in order to improve color in fabrics. Chevreul realized It was the eye, and not the dye, that had the greatest influence on color, and from this, he revolutionized color theory by grasping what came to be called the law of simultaneous contrast: that colors mutually influence one another when juxtaposed, each imposing its own complementary color on the other. The French painter Eugène Delacroix, who had been experimenting with what he called broken tones, embraced Chevreul's book, The Law of Contrast of Color (1839) with its explanations of how juxtaposed colors can enhance or diminish each other, and his exploration of all the visible colors of the spectrum. Inspired by Chevreul’s 1839 treatise, Delacroix passed his enthusiasm on to the young artists who were inspired by him. It was Chevreul who led the Impressionists to grasp that they should apply separate brushstrokes of pure color to a canvas and allow the viewer’s eye to combine them optically. They were aided greatly in this by innovations in oil paint itself. Since the Renaissance, painters had to grind pigment, add oil and thus create their own paints; these time-consuming paints also quickly dried out, making studio painting a necessity for large works, and limiting painters to mix one or two colors at a time and fill in an entire area using just that one color before it dried out. In 1841, a little-known American painter named John G. Rand invented a simple improvement without which the Impressionist movement could not have occurred: the small, flexible tin tube with removable cap in which oil paints could be stored. Oil paints kept in such tubes stayed moist, usable, and portable. For the first time since the Renaissance, painters were not trapped by the time frame of how quickly oil paint dried. Paints in tubes could be easily loaded up and carried out into the real world, to directly observe the play of color and natural light, in shadow and movement, to paint in the moment. Selling the oil paint in tubes also brought about the arrival of dazzling new pigments - chrome yellow, cadmium blue - invented by 19th century industrial chemists. The tubes freed the Impressionists to paint quickly, and across an entire canvas, rather than carefully delineated single-color sections at a time; in short, to sketch directly in oil - racing across the canvas in every color that came to hand and thus inspiring their name of "impressionists" - since such speedy, bold brushwork and dabs of separate colors made contemporary critics think their paintings were mere impressions, not finished paintings, which were to have no visible brush marks at all, seamless under layers of varnish. Pierre-Auguste Renoir said, “Without colors in tubes, there would be no Cézanne, no Monet, no Pissarro, and no Impressionism.” Finally, the careful, hyper-realistic techniques of French neo-classicism were seen as stiff and lifeless when compared to the remarkable new vision of the world as seen through the new invention of photography by the mid-1850s. It was not merely that the increasing ability of this new invention, particularly by the French inventor Daguerre, made the realism of the painted image redundant as he deliberately competed in the Paris diorama with large-scale historical paintings. The neo-classical subject matter, limited by Academic tradition to Greek and Roman legends, historical battles and Biblical stories, seemed oppressively clichéd and limited to artists eager to explore the actual world in front of their own eyes revealed by the camera - daily life, candid groupings of everyday people doing simple things, Paris itself, rural landscapes and most particularly the play of captured light - not the imaginary lionizing of unseen past events. Early photographs influenced Impressionist style by its use of asymmetry, cropping and most obviously the blurring of motion, as inadvertently captured in the very slow speeds of early photography. Edgar Degas, Claude Monet, Pierre-Auguste Renoir - in their framing, use of color, light and shadow, subject matter - put these innovations to work to create a new language of visual beauty and meaning. Faking revolution: the CIA and Abstract Expressionism Their initial break with realism into an exploration of light, color and the nature of paint was brought to an ultimate conclusion by the abstract expressionists who broke away from recognizable content of any kind into works of pure shape, color and painterliness which emerged at the end of the Second World War. At first thought of as primitive, inept works - as in "my four year old could do that - these works were misunderstood and neglected until given critical and support by the rise of art journalists and critics who championed their work in the 1940s and 50s, expressing the power of such work in aesthetic terms the artists themselves seldom used, or even understood. Jackson Pollock who pioneered splatter painting, dispensing with a paint brush altogether, soon became lionized as the angry young man in a large spread in Life magazine. In fact, in a deliberate, secret and successful effort to separate artistic revolutions from political ones, abstract expressionists like Pollock, Robert Motherwell, Willem de Kooning and Mark Rothko, while seemingly difficult, pathbreaking artists, were in fact secretly supported for twenty years by the Central Intelligence Agency (CIA) in a Cold War policy begun in 1947 to prove that the United States could foster more artistic freedom than the Soviet bloc. "It was recognized that Abstract Expressionism was the kind of art that made Socialist Realism look even more stylized and rigid and confined than it was," said former CIA case worker Donald Jameson, who finally broke the silence on this program in 1995. Ironically, the covert CIA support for these radical works was required because an attempt to use government funds for a European tour of these works during the Truman administration led to a public uproar in conservative McCarthy-era America, with Truman famously remarking, "If that's art, I'm a Hottentot." Thus, the program was hidden under the guise of fabricated foundations and the support of wealthy patrons who were actually using CIA funds, not their own, to sponsor traveling exhibitions of American abstract expressionists all over the world, publish books and articles praising them and to purchase and exhibit abstract expressionist works in major American and British museums. Thomas Braden, in charge of these cultural programs for the CIA, in the early years of the Cold War, had formerly been executive secretary of the Museum of Modern Art, America's leading institution for 20th century art and the charges of collusion between the two echoed for many years after this program was revealed, though most of the artists involved had no idea they were being used in this way and were furious when they found out.

Acoustics

Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, craft, science and technology have provoked one another to advance the whole, as in many other fields of knowledge. Robert Bruce Lindsay's "Wheel of Acoustics" is a well accepted overview of the various fields in acoustics. History Etymology The word "acoustic" is derived from the Greek word ἀκουστικός (akoustikos), meaning "of or for hearing, ready to hear" and that from ἀκουστός (akoustos), "heard, audible", which in turn derives from the verb ἀκούω(akouo), "I hear". The Latin synonym is "sonic", after which the term sonics used to be a synonym for acoustics and later a branch of acoustics. Frequencies above and below the audible range are called "ultrasonic" and "infrasonic", respectively. Early research in acoustics In the 6th century BC, the ancient Greek philosopher Pythagoras wanted to know why some combinations of musical sounds seemed more beautiful than others, and he found answers in terms of numerical ratios representing the harmonic overtone series on a string. He is reputed to have observed that when the lengths of vibrating strings are expressible as ratios of integers (e.g. 2 to 3, 3 to 4), the tones produced will be harmonious, and the smaller the integers the more harmonious the sounds. For example, a string of a certain length would sound particularly harmonious with a string of twice the length (other factors being equal). In modern parlance, if a string sounds the note C when plucked, a string twice as long will sound a C an octave lower. In one system of musical tuning, the tones in between are then given by 16:9 for D, 8:5 for E, 3:2 for F, 4:3 for G, 6:5 for A, and 16:15 for B, in ascending order. Aristotle (384–322 BC) understood that sound consisted of compressions and rarefactions of air which "falls upon and strikes the air which is next to it...", a very good expression of the nature of wave motion. On Things Heard, generally ascribed to Strato of Lampsacus, states that the pitch is related to the frequency of vibrations of the air and to the speed of sound. In about 20 BC, the Roman architect and engineer Vitruvius wrote a treatise on the acoustic properties of theaters including discussion of interference, echoes, and reverberation—the beginnings of architectural acoustics. In Book V of his De architectura (The Ten Books of Architecture) Vitruvius describes sound as a wave comparable to a water wave extended to three dimensions, which, when interrupted by obstructions, would flow back and break up following waves. He described the ascending seats in ancient theaters as designed to prevent this deterioration of sound and also recommended bronze vessels of appropriate sizes be placed in theaters to resonate with the fourth, fifth and so on, up to the double octave, in order to resonate with the more desirable, harmonious notes. During the Islamic golden age, Abū Rayhān al-Bīrūnī (973-1048) is believed to have postulated that the speed of sound was much slower than the speed of light. The physical understanding of acoustical processes advanced rapidly during and after the Scientific Revolution. Mainly Galileo Galilei (1564–1642) but also Marin Mersenne (1588–1648), independently, discovered the complete laws of vibrating strings (completing what Pythagoras and Pythagoreans had started 2000 years earlier). Galileo wrote "Waves are produced by the vibrations of a sonorous body, which spread through the air, bringing to the tympanum of the ear a stimulus which the mind interprets as sound", a remarkable statement that points to the beginnings of physiological and psychological acoustics. Experimental measurements of the speed of sound in air were carried out successfully between 1630 and 1680 by a number of investigators, prominently Mersenne. Meanwhile, Newton (1642–1727) derived the relationship for wave velocity in solids, a cornerstone of physical acoustics (Principia, 1687). Age of Enlightenment and onward Substantial progress in acoustics, resting on firmer mathematical and physical concepts, was made during the eighteenth century by Euler (1707–1783), Lagrange (1736–1813), and d'Alembert (1717–1783). During this era, continuum physics, or field theory, began to receive a definite mathematical structure. The wave equation emerged in a number of contexts, including the propagation of sound in air. In the nineteenth century the major figures of mathematical acoustics were Helmholtz in Germany, who consolidated the field of physiological acoustics, and Lord Rayleigh in England, who combined the previous knowledge with his own copious contributions to the field in his monumental work The Theory of Sound (1877). Also in the 19th century, Wheatstone, Ohm, and Henry developed the analogy between electricity and acoustics. The twentieth century saw a burgeoning of technological applications of the large body of scientific knowledge that was by then in place. The first such application was Sabine's groundbreaking work in architectural acoustics, and many others followed. Underwater acoustics was used for detecting submarines in the first World War. Sound recording and the telephone played important roles in a global transformation of society. Sound measurement and analysis reached new levels of accuracy and sophistication through the use of electronics and computing. The ultrasonic frequency range enabled wholly new kinds of application in medicine and industry. New kinds of transducers (generators and receivers of acoustic energy) were invented and put to use. Definition Acoustics is defined by ANSI/ASA S1.1-2013 as "(a) Science of sound, including its production, transmission, and effects, including biological and psychological effects. (b) Those qualities of a room that, together, determine its character with respect to auditory effects." The study of acoustics revolves around the generation, propagation and reception of mechanical waves and vibrations. The steps shown in the above diagram can be found in any acoustical event or process. There are many kinds of cause, both natural and volitional. There are many kinds of transduction process that convert energy from some other form into sonic energy, producing a sound wave. There is one fundamental equation that describes sound wave propagation, the acoustic wave equation, but the phenomena that emerge from it are varied and often complex. The wave carries energy throughout the propagating medium. Eventually this energy is transduced again into other forms, in ways that again may be natural and/or volitionally contrived. The final effect may be purely physical or it may reach far into the biological or volitional domains. The five basic steps are found equally well whether we are talking about an earthquake, a submarine using sonar to locate its foe, or a band playing in a rock concert. The central stage in the acoustical process is wave propagation. This falls within the domain of physical acoustics. In fluids, sound propagates primarily as a pressure wave. In solids, mechanical waves can take many forms including longitudinal waves, transverse waves and surface waves. Acoustics looks first at the pressure levels and frequencies in the sound wave and how the wave interacts with the environment. This interaction can be described as either a diffraction, interference or a reflection or a mix of the three. If several media are present, a refraction can also occur. Transduction processes are also of special importance to acoustics. Fundamental concepts Wave propagation: pressure levels In fluids such as air and water, sound waves propagate as disturbances in the ambient pressure level. While this disturbance is usually small, it is still noticeable to the human ear. The smallest sound that a person can hear, known as the threshold of hearing, is nine orders of magnitude smaller than the ambient pressure. The loudness of these disturbances is related to the sound pressure level (SPL) which is measured on a logarithmic scale in decibels. Wave propagation: frequency Physicists and acoustic engineers tend to discuss sound pressure levels in terms of frequencies, partly because this is how our ears interpret sound. What we experience as "higher pitched" or "lower pitched" sounds are pressure vibrations having a higher or lower number of cycles per second. In a common technique of acoustic measurement, acoustic signals are sampled in time, and then presented in more meaningful forms such as octave bands or time frequency plots. Both of these popular methods are used to analyze sound and better understand the acoustic phenomenon. The entire spectrum can be divided into three sections: audio, ultrasonic, and infrasonic. The audio range falls between 20 Hz and 20,000 Hz. This range is important because its frequencies can be detected by the human ear. This range has a number of applications, including speech communication and music. The ultrasonic range refers to the very high frequencies: 20,000 Hz and higher. This range has shorter wavelengths which allow better resolution in imaging technologies. Medical applications such as ultrasonography and elastography rely on the ultrasonic frequency range. On the other end of the spectrum, the lowest frequencies are known as the infrasonic range. These frequencies can be used to study geological phenomena such as earthquakes. Analytic instruments such as the spectrum analyzer facilitate visualization and measurement of acoustic signals and their properties. The spectrogram produced by such an instrument is a graphical display of the time varying pressure level and frequency profiles which give a specific acoustic signal its defining character. Transduction in acoustics A transducer is a device for converting one form of energy into another. In an electroacoustic context, this means converting sound energy into electrical energy (or vice versa). Electroacoustic transducers include loudspeakers, microphones, particle velocity sensors, hydrophones and sonar projectors. These devices convert a sound wave to or from an electric signal. The most widely used transduction principles are electromagnetism, electrostatics and piezoelectricity. The transducers in most common loudspeakers (e.g. woofers and tweeters), are electromagnetic devices that generate waves using a suspended diaphragm driven by an electromagnetic voice coil, sending off pressure waves. Electret microphones and condenser microphones employ electrostatics—as the sound wave strikes the microphone's diaphragm, it moves and induces a voltage change. The ultrasonic systems used in medical ultrasonography employ piezoelectric transducers. These are made from special ceramics in which mechanical vibrations and electrical fields are interlinked through a property of the material itself. Acoustician An acoustician is an expert in the science of sound. Education There are many types of acoustician, but they usually have a Bachelor's degree or higher qualification. Some possess a degree in acoustics, while others enter the discipline via studies in fields such as physics or engineering. Much work in acoustics requires a good grounding in Mathematics and science. Many acoustic scientists work in research and development. Some conduct basic research to advance our knowledge of the perception (e.g. hearing, psychoacoustics or neurophysiology) of speech, music and noise. Other acoustic scientists advance understanding of how sound is affected as it moves through environments, e.g. underwater acoustics, architectural acoustics or structural acoustics. Other areas of work are listed under subdisciplines below. Acoustic scientists work in government, university and private industry laboratories. Many go on to work in Acoustical Engineering. Some positions, such as Faculty (academic staff) require a Doctor of Philosophy. Subdisciplines Archaeoacoustics Archaeoacoustics, also known as the archaeology of sound, is one of the only ways to experience the past with senses other than our eyes. Archaeoacoustics is studied by testing the acoustic properties of prehistoric sites, including caves. Iegor Rezkinoff, a sound archaeologist, studies the acoustic properties of caves through natural sounds like humming and whistling. Archaeological theories of acoustics are focused around ritualistic purposes as well as a way of echolocation in the caves. In archaeology, acoustic sounds and rituals directly correlate as specific sounds were meant to bring ritual participants closer to a spiritual awakening. Parallels can also be drawn between cave wall paintings and the acoustic properties of the cave; they are both dynamic. Because archaeoacoustics is a fairly new archaeological subject, acoustic sound is still being tested in these prehistoric sites today. Aeroacoustics Aeroacoustics is the study of noise generated by air movement, for instance via turbulence, and the movement of sound through the fluid air. This knowledge is applied in acoustical engineering to study how to quieten aircraft. Aeroacoustics is important for understanding how wind musical instruments work. Acoustic signal processing Acoustic signal processing is the electronic manipulation of acoustic signals. Applications include: active noise control; design for hearing aids or cochlear implants; echo cancellation; music information retrieval, and perceptual coding (e.g. MP3 or Opus). Architectural acoustics Architectural acoustics (also known as building acoustics) involves the scientific understanding of how to achieve good sound within a building. It typically involves the study of speech intelligibility, speech privacy, music quality, and vibration reduction in the built environment. Commonly studied environments are hospitals, classrooms, dwellings, performance venues, recording and broadcasting studios. Focus considerations include room acoustics, airborne and impact transmission in building structures, airborne and structure-borne noise control, noise control of building systems and electroacoustic systems . Bioacoustics Bioacoustics is the scientific study of the hearing and calls of animal calls, as well as how animals are affected by the acoustic and sounds of their habitat. Electroacoustics This subdiscipline is concerned with the recording, manipulation and reproduction of audio using electronics. This might include products such as mobile phones, large scale public address systems or virtual reality systems in research laboratories. Environmental noise and soundscapes Environmental acoustics is concerned with noise and vibration caused by railways, road traffic, aircraft, industrial equipment and recreational activities. The main aim of these studies is to reduce levels of environmental noise and vibration. Research work now also has a focus on the positive use of sound in urban environments: soundscapes and tranquility. Musical acoustics Musical acoustics is the study of the physics of acoustic instruments; the audio signal processing used in electronic music; the computer analysis of music and composition, and the perception and cognitive neuroscience of music. Noise The goal this acoustics sub-discipline is to reduce the impact of unwanted sound. Scope of noise studies includes the generation, propagation, and impact on structures, objects, and people. Innovative model development Measurement techniques Mitigation strategies Inupt to the establishment of standards and regulations Noise research investigates the impact of noise on humans and animals to include work in definitions, abatement, transportation noise, hearing protection, Jet and rocket noise, building system noise and vibration, atmospheric sound propagation, soundscapes, and low-frequency sound. Psychoacoustics Many studies have been conducted to identify the relationship between acoustics and cognition, or more commonly known as psychoacoustics, in which what one hears is a combination of perception and biological aspects. The information intercepted by the passage of sound waves through the ear is understood and interpreted through the brain, emphasizing the connection between the mind and acoustics. Psychological changes have been seen as brain waves slow down or speed up as a result of varying auditory stimulus which can in turn affect the way one thinks, feels, or even behaves. This correlation can be viewed in normal, everyday situations in which listening to an upbeat or uptempo song can cause one's foot to start tapping or a slower song can leave one feeling calm and serene. In a deeper biological look at the phenomenon of psychoacoustics, it was discovered that the central nervous system is activated by basic acoustical characteristics of music. By observing how the central nervous system, which includes the brain and spine, is influenced by acoustics, the pathway in which acoustic affects the mind, and essentially the body, is evident. Speech Acousticians study the production, processing and perception of speech. Speech recognition and Speech synthesis are two important areas of speech processing using computers. The subject also overlaps with the disciplines of physics, physiology, psychology, and linguistics. Structural Vibration and Dynamics Structural acoustics is the study of motions and interactions of mechanical systems with their environments and the methods of their measurement, analysis, and control . There are several sub-disciplines found within this regime: Modal Analysis Material characterization Structural health monitoring Acoustic Metamaterials Friction Acoustics Applications might include: ground vibrations from railways; vibration isolation to reduce vibration in operating theatres; studying how vibration can damage health (vibration white finger); vibration control to protect a building from earthquakes, or measuring how structure-borne sound moves through buildings. Ultrasonics Ultrasonics deals with sounds at frequencies too high to be heard by humans. Specialisms include medical ultrasonics (including medical ultrasonography), sonochemistry, ultrasonic testing, material characterisation and underwater acoustics (sonar). Underwater acoustics Underwater acoustics is the scientific study of natural and man-made sounds underwater. Applications include sonar to locate submarines, underwater communication by whales, climate change monitoring by measuring sea temperatures acoustically, sonic weapons, and marine bioacoustics.

Atomic physics

Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. Atomic physics typically refers to the study of atomic structure and the interaction between atoms. It is primarily concerned with the way in which electrons are arranged around the nucleus and the processes by which these arrangements change. This comprises ions, neutral atoms and, unless otherwise stated, it can be assumed that the term atom includes ions. The term atomic physics can be associated with nuclear power and nuclear weapons, due to the synonymous use of atomic and nuclear in standard English. Physicists distinguish between atomic physics—which deals with the atom as a system consisting of a nucleus and electrons—and nuclear physics, which studies nuclear reactions and special properties of atomic nuclei. As with many scientific fields, strict delineation can be highly contrived and atomic physics is often considered in the wider context of atomic, molecular, and optical physics. Physics research groups are usually so classified. Isolated atoms Atomic physics primarily considers atoms in isolation. Atomic models will consist of a single nucleus that may be surrounded by one or more bound electrons. It is not concerned with the formation of molecules (although much of the physics is identical), nor does it examine atoms in a solid state as condensed matter. It is concerned with processes such as ionization and excitation by photons or collisions with atomic particles. While modelling atoms in isolation may not seem realistic, if one considers atoms in a gas or plasma then the time-scales for atom-atom interactions are huge in comparison to the atomic processes that are generally considered. This means that the individual atoms can be treated as if each were in isolation, as the vast majority of the time they are. By this consideration, atomic physics provides the underlying theory in plasma physics and atmospheric physics, even though both deal with very large numbers of atoms. Electronic configuration Electrons form notional shells around the nucleus. These are normally in a ground state but can be excited by the absorption of energy from light (photons), magnetic fields, or interaction with a colliding particle (typically ions or other electrons). Electrons that populate a shell are said to be in a bound state. The energy necessary to remove an electron from its shell (taking it to infinity) is called the binding energy. Any quantity of energy absorbed by the electron in excess of this amount is converted to kinetic energy according to the conservation of energy. The atom is said to have undergone the process of ionization. If the electron absorbs a quantity of energy less than the binding energy, it will be transferred to an excited state. After a certain time, the electron in an excited state will "jump" (undergo a transition) to a lower state. In a neutral atom, the system will emit a photon of the difference in energy, since energy is conserved. If an inner electron has absorbed more than the binding energy (so that the atom ionizes), then a more outer electron may undergo a transition to fill the inner orbital. In this case, a visible photon or a characteristic X-ray is emitted, or a phenomenon known as the Auger effect may take place, where the released energy is transferred to another bound electron, causing it to go into the continuum. The Auger effect allows one to multiply ionize an atom with a single photon. There are rather strict selection rules as to the electronic configurations that can be reached by excitation by light — however, there are no such rules for excitation by collision processes. History and developments One of the earliest steps towards atomic physics was the recognition that matter was composed of atoms. It forms a part of the texts written in 6th century BC to 2nd century BC, such as those of Democritus or written by . This theory was later developed in the modern sense of the basic unit of a chemical element by the British chemist and physicist John Dalton in the 18th century. At this stage, it wasn't clear what atoms were, although they could be described and classified by their properties (in bulk). The invention of the periodic system of elements by Dmitri Mendeleev was another great step forward. The true beginning of atomic physics is marked by the discovery of spectral lines and attempts to describe the phenomenon, most notably by Joseph von Fraunhofer. The study of these lines led to the Bohr atom model and to the birth of quantum mechanics. In seeking to explain atomic spectra, an entirely new mathematical model of matter was revealed. As far as atoms and their electron shells were concerned, not only did this yield a better overall description, i.e. the atomic orbital model, but it also provided a new theoretical basis for chemistry (quantum chemistry) and spectroscopy. Since the Second World War, both theoretical and experimental fields have advanced at a rapid pace. This can be attributed to progress in computing technology, which has allowed larger and more sophisticated models of atomic structure and associated collision processes. Similar technological advances in accelerators, detectors, magnetic field generation and lasers have greatly assisted experimental work.

Anglicanism

Anglicanism is a Western Christian tradition that has developed from the practices, liturgy, and identity of the Church of England following the English Reformation, in the context of the Protestant Reformation in Europe. It is one of the largest branches of Christianity, with around 110 million adherents worldwide . Adherents of Anglicanism are called Anglicans; they are also called Episcopalians in some countries. The majority of Anglicans are members of national or regional ecclesiastical provinces of the international Anglican Communion, which forms the third-largest Christian communion in the world, after the Roman Catholic Church and the Eastern Orthodox Church. These provinces are in full communion with the See of Canterbury and thus with the Archbishop of Canterbury, whom the communion refers to as its primus inter pares (Latin, 'first among equals'). The Archbishop calls the decennial Lambeth Conference, chairs the meeting of primates, and is the president of the Anglican Consultative Council. Some churches that are not part of the Anglican Communion or recognised by it, also call themselves Anglican, including those that are within the Continuing Anglican movement and Anglican realignment. Anglicans base their Christian faith on the Bible, traditions of the apostolic church, apostolic succession ("historic episcopate"), and the writings of the Church Fathers. Anglicanism forms one of the branches of Western Christianity, having definitively declared its independence from the Holy See at the time of the Elizabethan Religious Settlement. Many of the new Anglican formularies of the mid-16th century corresponded closely to those of historical Protestantism. These reforms in the Church of England were understood by one of those most responsible for them, Thomas Cranmer, the Archbishop of Canterbury, and others as navigating a middle way between two of the emerging Protestant traditions, namely Lutheranism and Calvinism. In the first half of the 17th century, the Church of England and its associated Church of Ireland were presented by some Anglican divines as comprising a distinct Christian tradition, with theologies, structures, and forms of worship representing a different kind of middle way, or via media, between Protestantism and Catholicism – a perspective that came to be highly influential in later theories of Anglican identity and expressed in the description of Anglicanism as "catholic and reformed". The degree of distinction between Protestant and Catholic tendencies within the Anglican tradition is routinely a matter of debate both within specific Anglican churches and throughout the Anglican Communion. Unique to Anglicanism is the Book of Common Prayer, the collection of services in one prayer book used for centuries. The book is acknowledged as a principal tie which binds the Anglican Communion together as a liturgical rather than a confessional tradition or one possessing a magisterium as in the Roman Catholic Church. After the American Revolution, Anglican congregations in the United States and British North America (which would later form the basis for the modern country of Canada) were each reconstituted into autonomous churches with their own bishops and self-governing structures; these were known as the American Episcopal Church and the Church of England in the Dominion of Canada. Through the expansion of the British Empire and the activity of Christian missions, this model was adopted as the model for many newly formed churches, especially in Africa, Australasia, and the Asia-Pacific. In the 19th century, the term Anglicanism was coined to describe the common religious tradition of these churches; as also that of the Scottish Episcopal Church, which, though originating earlier within the Church of Scotland, had come to be recognised as sharing this common identity. Terminology The word Anglican originates in , a phrase from the Magna Carta dated 15 June 1215, meaning "the Anglican Church shall be free". Adherents of Anglicanism are called Anglicans. As an adjective, "Anglican" is used to describe the people, institutions, and churches, as well as the liturgical traditions and theological concepts developed by the Church of England. As a noun, an Anglican is a member of a church in the Anglican Communion. The word is also used by followers of separated groups which have left the communion or have been founded separately from it, although this is considered as a misuse by the Anglican Communion. The word Anglicanism came into being in the 19th century. The word originally referred only to the teachings and rites of Christians throughout the world in communion with the see of Canterbury, but has come to sometimes be extended to any church following those traditions rather than actual membership in the modern Anglican Communion. Although the term Anglican is found referring to the Church of England as far back as the 16th century, its use did not become general until the latter half of the 19th century. In British parliamentary legislation referring to the English Established Church, there is no need for a description; it is simply the Church of England, though the word "Protestant" is used in many legal acts specifying the succession to the Crown and qualifications for office. When the Union with Ireland Act created the United Church of England and Ireland, it is specified that it shall be one "Protestant Episcopal Church", thereby distinguishing its form of church government from the Presbyterian polity that prevails in the Church of Scotland. The word Episcopal is preferred in the title of the Episcopal Church (the province of the Anglican Communion covering the United States) and the Scottish Episcopal Church, though the full name of the former is The Protestant Episcopal Church in the United States of America. Elsewhere, however, the term "Anglican Church" came to be preferred as it distinguished these churches from others that maintain an episcopal polity. Definition Anglicanism, in its structures, theology, and forms of worship, is commonly understood as a distinct Christian tradition representing a middle ground between what are perceived to be the extremes of the claims of 16th-century Roman Catholicism and the Lutheran and Reformed varieties of Protestantism of that era. As such, it is often referred to as being a via media (or "middle way") between these traditions. The faith of Anglicans is founded in the Scriptures and the Gospels, the traditions of the Apostolic Church, the historical episcopate, the first four ecumenical councils, and the early Church Fathers (among these councils, especially the premier four ones, and among these Fathers, especially those active during the five initial centuries of Christianity, according to the quinquasaecularist principle proposed by the English bishop Lancelot Andrewes and the Lutheran dissident Georg Calixtus). Anglicans understand the Old and New Testaments as "containing all things necessary for salvation" and as being the rule and ultimate standard of faith. Reason and tradition are seen as valuable means to interpret scripture (a position first formulated in detail by Richard Hooker), but there is no full mutual agreement among Anglicans about exactly how scripture, reason, and tradition interact (or ought to interact) with each other. Anglicans understand the Apostles' Creed as the baptismal symbol and the Nicene Creed as the sufficient statement of the Christian faith. Anglicans believe the catholic and apostolic faith is revealed in Holy Scripture and the Catholic creeds and interpret these in light of the Christian tradition of the historic church, scholarship, reason, and experience. Anglicans celebrate the traditional sacraments, with special emphasis being given to the Eucharist, also called Holy Communion, the Lord's Supper or the Mass. The Eucharist is central to worship for most Anglicans as a communal offering of prayer and praise in which the life, death, and resurrection of Jesus Christ are proclaimed through prayer, reading of the Bible, singing, giving God thanks over the bread and wine for the innumerable benefits obtained through the passion of Christ, the breaking of the bread, the blessing of the cup, and the partaking of the body and blood of Christ as instituted at the Last Supper, however one wished to define the Presence. The consecrated bread and wine, which are the true body and blood of Christ after a spiritual manner, are outward symbols of an inner grace given by Christ, which to the repentant conveys forgiveness and cleaning from sin. While many Anglicans celebrate the Eucharist in similar ways to the predominant western Catholic tradition, a considerable degree of liturgical freedom is permitted, and worship styles range from the simple to elaborate. Unique to Anglicanism is the Book of Common Prayer (BCP), the collection of services that worshippers in most Anglican churches have used for centuries. It was called common prayer originally because it was intended for use in all Church of England churches, which had previously followed differing local liturgies. The term was kept when the church became international, because all Anglicans used to share in its use around the world. In 1549, the first Book of Common Prayer was compiled by Thomas Cranmer, who was then Archbishop of Canterbury. While it has since undergone many revisions and Anglican churches in different countries have developed other service books, the Prayer Book is still acknowledged as one of the ties that bind Anglicans together. Identity Early history The founding of Christianity in Britain is commonly attributed to Joseph of Arimathea, according to Anglican legend, and is commemorated in Glastonbury Abbey. Many of the early Church Fathers wrote of the presence of Christianity in Roman Britain, with Tertullian stating "those parts of Britain into which the Roman arms had never penetrated were become subject to Christ". Saint Alban, who was executed in AD 209, is the first Christian martyr in the British Isles. For this reason he is venerated as the British protomartyr. The historian Heinrich Zimmer writes that "Just as Britain was a part of the Roman Empire, so the British Church formed (during the fourth century) a branch of the Catholic Church of the West; and during the whole of that century, from the Council of Arles (316) onward, took part in all proceedings concerning the Church." After Roman troops withdrew from Britain, the "absence of Roman military and governmental influence and overall decline of Roman imperial political power enabled Britain and the surrounding isles to develop distinctively from the rest of the West. A new culture emerged around the Irish Sea among the Celtic peoples with Celtic Christianity at its core. What resulted was a form of Christianity distinct from Rome in many traditions and practices." The historian Charles Thomas, in addition to the Celticist Heinrich Zimmer, writes that the distinction between sub-Roman and post-Roman Insular Christianity, also known as Celtic Christianity, began to become apparent around AD 475, with the Celtic churches allowing married clergy, observing Lent and Easter according to their own calendar, and having a different tonsure; moreover, like the Eastern Orthodox and the Oriental Orthodox Churches, the Celtic churches operated independently of the Pope's authority, as a result of their isolated development in the British Isles. In what is known as the Gregorian mission, Pope Gregory I sent Augustine of Canterbury to the British Isles in AD 596, with the purpose of evangelising the pagans there (who were largely Anglo-Saxons), as well as to reconcile the Celtic churches in the British Isles to the See of Rome. In Kent, Augustine persuaded the Anglo-Saxon king "Æthelberht and his people to accept Christianity". Augustine, on two occasions, "met in conference with members of the Celtic episcopacy, but no understanding was reached between them." Eventually, the "Christian Church of the Anglo-Saxon kingdom of Northumbria convened the Synod of Whitby in 663/664 to decide whether to follow Celtic or Roman usages." This meeting, with King Oswiu as the final decision maker, "led to the acceptance of Roman usage elsewhere in England and brought the English Church into close contact with the Continent". As a result of assuming Roman usages, the Celtic Church surrendered its independence, and, from this point on, the Church in England "was no longer purely Celtic, but became Anglo-Roman-Celtic". The theologian Christopher L. Webber writes that, although "the Roman form of Christianity became the dominant influence in Britain as in all of western Europe, Anglican Christianity has continued to have a distinctive quality because of its Celtic heritage." The Church in England remained united with Rome until the English Parliament, through the Act of Supremacy (1534), declared King Henry VIII to be the Supreme Head of the Church of England to fulfill the "English desire to be independent from continental Europe religiously and politically." As the change was mostly political, done in order to allow for the annulment of Henry VIII's marriage, the English Church under Henry VIII continued to maintain Roman Catholic doctrines and the sacraments despite the separation from Rome. With little exception, Henry VIII allowed no changes during his lifetime. Under King Edward VI (1547–1553), however, the church in England underwent what is known as the English Reformation, in the course of which it acquired a number of characteristics that would subsequently become recognised as constituting its distinctive "Anglican" identity. Development With the Elizabethan Settlement of 1559, the Protestant identity of the English and Irish churches was affirmed by means of parliamentary legislation which mandated allegiance and loyalty to the English Crown in all their members. The Elizabethan church began to develop distinct religious traditions, assimilating some of the theology of Reformed churches with the services in the Book of Common Prayer (which drew extensively on the Sarum Rite native to England), under the leadership and organisation of a continuing episcopate. Over the years, these traditions themselves came to command adherence and loyalty. The Elizabethan Settlement stopped the radical Protestant tendencies under Edward VI by combining the more radical elements of the Second Prayer Book of 1552 with the conservative "Catholic" First Prayer Book of 1549. From then on, Protestantism was in a "state of arrested development", regardless of the attempts to detach the Church of England from its "idiosyncratic anchorage in the medieval past" by various groups which tried to push it towards a more Reformed theology and governance in the years 1560–1660. Although two important constitutive elements of what later would emerge as Anglicanism were present in 1559 – scripture, the historic episcopate, the Book of Common Prayer, the teachings of the First Four Ecumenical Councils as the yardstick of catholicity, the teaching of the Church Fathers and Catholic bishops, and informed reason – neither the laypeople nor the clergy perceived themselves as Anglicans at the beginning of Elizabeth I's reign, as there was no such identity. Neither does the term via media appear until the 1627 to describe a church which refused to identify itself definitely as Catholic or Protestant, or as both, "and had decided in the end that this is virtue rather than a handicap". Historical studies on the period 1560–1660 written before the late 1960s tended to project the predominant conformist spirituality and doctrine of the 1660s on the ecclesiastical situation one hundred years before, and there was also a tendency to take polemically binary partitions of reality claimed by contestants studied (such as the dichotomies Protestant-"Popish" or "Laudian"-"Puritan") at face value. Since the late 1960s, these interpretations have been criticised. Studies on the subject written during the last forty-five years have, however, not reached any consensus on how to interpret this period in English church history. The extent to which one or several positions concerning doctrine and spirituality existed alongside the more well-known and articulate Puritan movement and the Durham House Party, and the exact extent of continental Calvinism among the English elite and among the ordinary churchgoers from the 1560s to the 1620s are subjects of current and ongoing debate. In 1662, under King Charles II, a revised Book of Common Prayer was produced, which was acceptable to high churchmen as well as some Puritans, and is still considered authoritative to this day. In so far as Anglicans derived their identity from both parliamentary legislation and ecclesiastical tradition, a crisis of identity could result wherever secular and religious loyalties came into conflict – and such a crisis indeed occurred in 1776 with the American Declaration of Independence, most of whose signatories were, at least nominally, Anglican. For these American patriots, even the forms of Anglican services were in doubt, since the Prayer Book rites of Matins, Evensong, and Holy Communion all included specific prayers for the British Royal Family. Consequently, the conclusion of the War of Independence eventually resulted in the creation of two new Anglican churches, the Episcopal Church in the United States in those states that had achieved independence; and in the 1830s The Church of England in Canada became independent from the Church of England in those North American colonies which had remained under British control and to which many Loyalist churchmen had migrated. Reluctantly, legislation was passed in the British Parliament (the Consecration of Bishops Abroad Act 1786) to allow bishops to be consecrated for an American church outside of allegiance to the British Crown (since no dioceses had ever been established in the former American colonies). Both in the United States and in Canada, the new Anglican churches developed novel models of self-government, collective decision-making, and self-supported financing; that would be consistent with separation of religious and secular identities. In the following century, two further factors acted to accelerate the development of a distinct Anglican identity. From 1828 and 1829, Dissenters and Catholics could be elected to the House of Commons, which consequently ceased to be a body drawn purely from the established churches of Scotland, England, and Ireland; but which nevertheless, over the following ten years, engaged in extensive reforming legislation affecting the interests of the English and Irish churches; which, by the Acts of Union of 1800, had been reconstituted as the United Church of England and Ireland. The propriety of this legislation was bitterly contested by the Oxford Movement (Tractarians), who in response developed a vision of Anglicanism as religious tradition deriving ultimately from the ecumenical councils of the patristic church. Those within the Church of England opposed to the Tractarians, and to their revived ritual practices, introduced a stream of bills in parliament aimed to control innovations in worship. This only made the dilemma more acute, with consequent continual litigation in the secular and ecclesiastical courts. Over the same period, Anglican churches engaged vigorously in Christian missions, resulting in the creation, by the end of the century, of over ninety colonial bishoprics, which gradually coalesced into new self-governing churches on the Canadian and American models. However, the case of John Colenso, Bishop of Natal, reinstated in 1865 by the English Judicial Committee of the Privy Council over the heads of the Church in South Africa, demonstrated acutely that the extension of episcopacy had to be accompanied by a recognised Anglican ecclesiology of ecclesiastical authority, distinct from secular power. Consequently, at the instigation of the bishops of Canada and South Africa, the first Lambeth Conference was called in 1867; to be followed by further conferences in 1878 and 1888, and thereafter at ten-year intervals. The various papers and declarations of successive Lambeth Conferences have served to frame the continued Anglican debate on identity, especially as relating to the possibility of ecumenical discussion with other churches. This ecumenical aspiration became much more of a possibility, as other denominational groups rapidly followed the example of the Anglican Communion in founding their own transnational alliances: the Alliance of Reformed Churches, the Ecumenical Methodist Council, the International Congregational Council, and the Baptist World Alliance. Theories Anglicanism was seen as a middle way, or via media, between two branches of Protestantism, Lutheranism and Reformed Christianity. In their rejection of absolute parliamentary authority, the Tractarians – and in particular John Henry Newman – looked back to the writings of 17th-century Anglican divines, finding in these texts the idea of the English church as a via media between the Protestant and Catholic traditions. This view was associated – especially in the writings of Edward Bouverie Pusey – with the theory of Anglicanism as one of three "branches" (alongside the Roman Catholic Church and the Orthodox Church) historically arising out of the common tradition of the earliest ecumenical councils. Newman himself subsequently rejected his theory of the via media, as essentially historicist and static and hence unable to accommodate any dynamic development within the church. Nevertheless, the aspiration to ground Anglican identity in the writings of the 17th-century divines and in faithfulness to the traditions of the Church Fathers reflects a continuing theme of Anglican ecclesiology, most recently in the writings of Henry Robert McAdoo. The Tractarian formulation of the theory of the via media between Protestantism and Roman Catholicism was essentially a party platform, and not acceptable to Anglicans outside the confines of the Oxford Movement. However, this theory of the via media was reworked in the ecclesiological writings of Frederick Denison Maurice, in a more dynamic form that became widely influential. Both Maurice and Newman saw the Church of England of their day as sorely deficient in faith; but whereas Newman had looked back to a distant past when the light of faith might have appeared to burn brighter, Maurice looked forward to the possibility of a brighter revelation of faith in the future. Maurice saw the Protestant and Catholic strands within the Church of England as contrary but complementary, both maintaining elements of the true church, but incomplete without the other; such that a true catholic and evangelical church might come into being by a union of opposites. Central to Maurice's perspective was his belief that the collective elements of family, nation, and church represented a divine order of structures through which God unfolds his continuing work of creation. Hence, for Maurice, the Protestant tradition had maintained the elements of national distinction which were amongst the marks of the true universal church, but which had been lost within contemporary Roman Catholicism in the internationalism of centralised papal authority. Within the coming universal church that Maurice foresaw, national churches would each maintain the six signs of Catholicity: baptism, Eucharist, the creeds, Scripture, an episcopal ministry, and a fixed liturgy (which could take a variety of forms in accordance with divinely ordained distinctions in national characteristics). Not surprisingly, this vision of a becoming universal church as a congregation of autonomous national churches proved highly congenial in Anglican circles; and Maurice's six signs were adapted to form the Chicago-Lambeth Quadrilateral of 1888. In the latter decades of the 20th century, Maurice's theory, and the various strands of Anglican thought that derived from it, have been criticised by Stephen Sykes, who argues that the terms Protestant and Catholic as used in these approaches are synthetic constructs denoting ecclesiastic identities unacceptable to those to whom the labels are applied. Hence, the Catholic Church does not regard itself as a party or strand within the universal church – but rather identifies itself as the universal church. Moreover, Sykes criticises the proposition, implicit in theories of via media, that there is no distinctive body of Anglican doctrines, other than those of the universal church; accusing this of being an excuse not to undertake systematic doctrine at all. Contrariwise, Sykes notes a high degree of commonality in Anglican liturgical forms and in the doctrinal understandings expressed within those liturgies. He proposes that Anglican identity might rather be found within a shared consistent pattern of prescriptive liturgies, established and maintained through canon law, and embodying both a historic deposit of formal statements of doctrine, and also framing the regular reading and proclamation of scripture. Sykes nevertheless agrees with those heirs of Maurice who emphasise the incompleteness of Anglicanism as a positive feature, and quotes with qualified approval the words of Michael Ramsey: Doctrine "Catholic and reformed" The distinction between Reformed and Catholic, and the coherence of the two, is a matter of debate within the Anglican Communion. The Oxford Movement of the mid-19th century revived and extended doctrinal, liturgical, and pastoral practices similar to those of Roman Catholicism. This extends beyond the ceremony of high church services to even more theologically significant territory, such as sacramental theology (see Anglican sacraments). While Anglo-Catholic practices, particularly liturgical ones, have become more common within the tradition over the last century, there are also places where practices and beliefs resonate more closely with the evangelical movements of the 1730s (see Sydney Anglicanism). Guiding principles For high-church Anglicans, doctrine is neither established by a magisterium, nor derived from the theology of an eponymous founder (such as Calvinism), nor summed up in a confession of faith beyond the ecumenical creeds (such as the Lutheran Book of Concord). For them, the earliest Anglican theological documents are its prayer books, which they see as the products of profound theological reflection, compromise, and synthesis. They emphasise the Book of Common Prayer as a key expression of Anglican doctrine. The principle of looking to the prayer books as a guide to the parameters of belief and practice is called by the Latin name lex orandi, lex credendi ("the law of prayer is the law of belief"). Within the prayer books are the fundamentals of Anglican doctrine: the Apostles' and Nicene creeds, the Athanasian Creed (now rarely used), the scriptures (via the lectionary), the sacraments, daily prayer, the catechism, and apostolic succession in the context of the historic threefold ministry. For some low-church and evangelical Anglicans, the 16th-century Reformed Thirty-Nine Articles form the basis of doctrine. Distinctives of Anglican belief The Thirty-Nine Articles played a significant role in Anglican doctrine and practice. Following the passing of the 1604 canons, all Anglican clergy had to formally subscribe to the articles. Today, however, the articles are no longer binding, but are seen as a historical document which has played a significant role in the shaping of Anglican identity. The degree to which each of the articles has remained influential varies. On the doctrine of justification, for example, there is a wide range of beliefs within the Anglican Communion, with some Anglo-Catholics arguing for a faith with good works and the sacraments. At the same time, however, some evangelical Anglicans ascribe to the Reformed emphasis on sola fide ("faith alone") in their doctrine of justification (see Sydney Anglicanism). Still other Anglicans adopt a nuanced view of justification, taking elements from the early Church Fathers, Catholicism, Protestantism, liberal theology, and latitudinarian thought. Arguably, the most influential of the original articles has been Article VI on the "sufficiency of scripture", which says that "Scripture containeth all things necessary to salvation: so that whatsoever is not read therein, nor may be proved thereby, is not to be required of any man, that it should be believed as an article of the Faith, or be thought requisite or necessary to salvation." This article has informed Anglican biblical exegesis and hermeneutics since earliest times. Anglicans look for authority in their "standard divines" (see below). Historically, the most influential of these – apart from Cranmer – has been the 16th-century cleric and theologian Richard Hooker, who after 1660 was increasingly portrayed as the founding father of Anglicanism. Hooker's description of Anglican authority as being derived primarily from scripture, informed by reason (the intellect and the experience of God) and tradition (the practices and beliefs of the historical church), has influenced Anglican self-identity and doctrinal reflection perhaps more powerfully than any other formula. The analogy of the "three-legged stool" of scripture, reason, and tradition is often incorrectly attributed to Hooker. Rather, Hooker's description is a hierarchy of authority, with scripture as foundational and reason and tradition as vitally important, but secondary, authorities. Finally, the extension of Anglicanism into non-English cultures, the growing diversity of prayer books, and the increasing interest in ecumenical dialogue have led to further reflection on the parameters of Anglican identity. Many Anglicans look to the Chicago-Lambeth Quadrilateral of 1888 as the sine qua non of communal identity. In brief, the quadrilateral's four points are the scriptures as containing all things necessary to salvation; the creeds (specifically, the Apostles' and Nicene Creeds) as the sufficient statement of Christian faith; the dominical sacraments of Baptism and Holy Communion; and the historic episcopate. Divines Within the Anglican tradition, "divines" are clergy of the Church of England whose theological writings have been considered standards for faith, doctrine, worship, and spirituality, and whose influence has permeated the Anglican Communion in varying degrees through the years. While there is no authoritative list of these Anglican divines, there are some whose names would likely be found on most lists – those who are commemorated in lesser feasts of the Anglican churches and those whose works are frequently anthologised. The corpus produced by Anglican divines is diverse. What they have in common is a commitment to the faith as conveyed by scripture and the Book of Common Prayer, thus regarding prayer and theology in a manner akin to that of the Apostolic Fathers. On the whole, Anglican divines view the via media of Anglicanism not as a compromise, but as "a positive position, witnessing to the universality of God and God's kingdom working through the fallible, earthly ecclesia Anglicana". These theologians regard scripture as interpreted through tradition and reason as authoritative in matters concerning salvation. Reason and tradition, indeed, is extant in and presupposed by scripture, thus implying co-operation between God and humanity, God and nature, and between the sacred and secular. Faith is thus regarded as incarnational and authority as dispersed. Amongst the early Anglican divines of the 16th and 17th centuries, the names of Thomas Cranmer, John Jewel, Matthew Parker, Richard Hooker, Lancelot Andrewes, and Jeremy Taylor predominate. The influential character of Hooker's Of the Laws of Ecclesiastical Polity cannot be overestimated. Published in 1593 and subsequently, Hooker's eight-volume work is primarily a treatise on church-state relations, but it deals comprehensively with issues of biblical interpretation, soteriology, ethics, and sanctification. Throughout the work, Hooker makes clear that theology involves prayer and is concerned with ultimate issues and that theology is relevant to the social mission of the church. The 18th century saw the rise of two important movements in Anglicanism: Cambridge Platonism, with its mystical understanding of reason as the "candle of the Lord", and the evangelical revival, with its emphasis on the personal experience of the Holy Spirit. The Cambridge Platonist movement evolved into a school called Latitudinarianism, which emphasised reason as the barometer of discernment and took a stance of indifference towards doctrinal and ecclesiological differences. The evangelical revival, influenced by such figures as John Wesley and Charles Simeon, re-emphasised the importance of justification through faith and the consequent importance of personal conversion. Some in this movement, such as Wesley and George Whitefield, took the message to the United States, influencing the First Great Awakening and creating an Anglo-American movement called Methodism that would eventually break away, structurally, from the Anglican churches after the American Revolution. By the 19th century, there was a renewed interest in pre-Reformation English religious thought and practice. Theologians such as John Keble, Edward Bouverie Pusey, and John Henry Newman had widespread influence in the realm of polemics, homiletics and theological and devotional works, not least because they largely repudiated the old high-church tradition and replaced it with a dynamic appeal to antiquity which looked beyond the Reformers and Anglican formularies. Their work is largely credited with the development of the Oxford Movement, which sought to reassert Catholic identity and practice in Anglicanism. In contrast to this movement, clergy such as the Bishop of Liverpool, J. C. Ryle, sought to uphold the distinctly Reformed identity of the Church of England. He was not a servant of the status quo, but argued for a lively religion which emphasised grace, holy and charitable living, and the plain use of the 1662 Book of Common Prayer (interpreted in a partisan evangelical way) without additional rituals. Frederick Denison Maurice, through such works as The Kingdom of Christ, played a pivotal role in inaugurating another movement, Christian socialism. In this, Maurice transformed Hooker's emphasis on the incarnational nature of Anglican spirituality to an imperative for social justice. In the 19th century, Anglican biblical scholarship began to assume a distinct character, represented by the so-called "Cambridge triumvirate" of Joseph Lightfoot, F. J. A. Hort, and Brooke Foss Westcott. Their orientation is best summed up by Westcott's observation that "Life which Christ is and which Christ communicates, the life which fills our whole beings as we realise its capacities, is active fellowship with God." The earlier part of the 20th century is marked by Charles Gore, with his emphasis on natural revelation, and William Temple's focus on Christianity and society, while, from outside England, Robert Leighton, Archbishop of Glasgow, and several clergy from the United States have been suggested, such as William Porcher DuBose, John Henry Hobart (1775–1830, Bishop of New York 1816–30), William Meade, Phillips Brooks, and Charles Brent. Churchmanship Churchmanship can be defined as the manifestation of theology in the realms of liturgy, piety and, to some extent, spirituality. Anglican diversity in this respect has tended to reflect the diversity in the tradition's Reformed and Catholic identity. Different individuals, groups, parishes, dioceses and provinces may identify more closely with one or the other, or some mixture of the two. The range of Anglican belief and practice became particularly divisive during the 19th century, when some clergy were disciplined and even imprisoned on charges of introducing illegal ritual while, at the same time, others were criticised for engaging in public worship services with ministers of Reformed churches. Resistance to the growing acceptance and restoration of traditional Catholic ceremonial by the mainstream of Anglicanism ultimately led to the formation of small breakaway churches such as the Free Church of England in England (1844) and the Reformed Episcopal Church in North America (1873). Anglo-Catholic (and some broad-church) Anglicans celebrate public liturgy in ways that understand worship to be something very special and of utmost importance. Vestments are worn by the clergy, sung settings are often used, and incense may be used. Nowadays, in most Anglican churches, the Eucharist is celebrated in a manner similar to the usage of Roman Catholics and some Lutherans, though, in many churches, more traditional, "pre–Vatican II" models of worship are common (e.g., an "eastward orientation" at the altar). Whilst many Anglo-Catholics derive much of their liturgical practice from that of the pre-Reformation English church, others more closely follow traditional Roman Catholic practices. The Eucharist may sometimes be celebrated in the form known as High Mass, with a priest, deacon and subdeacon (usually actually a layman) dressed in traditional vestments, with incense and sanctus bells and prayers adapted from the Roman Missal or other sources by the celebrant. Such churches may also have forms of eucharistic adoration such as Benediction of the Blessed Sacrament. In terms of personal piety, some Anglicans may recite the Rosary and Angelus, be involved in a devotional society dedicated to "Our Lady" (the Blessed Virgin Mary) and seek the intercession of the saints. In recent decades, the prayer books of several provinces have, out of deference to a greater agreement with Eastern Conciliarism (and a perceived greater respect accorded Anglicanism by Eastern Orthodoxy than by Roman Catholicism), instituted a number of historically Eastern and Oriental Orthodox elements in their liturgies, including introduction of the Trisagion and deletion of the filioque clause from the Nicene Creed. For their part, those evangelical (and some broad-church) Anglicans who emphasise the more Protestant aspects of the Church stress the Reformation theme of salvation by grace through faith. They emphasise the two dominical sacraments of Baptism and Eucharist, viewing the other five as "lesser rites". Some evangelical Anglicans may even tend to take the inerrancy of scripture literally, adopting the view of Article VI that it contains all things necessary to salvation in an explicit sense. Worship in churches influenced by these principles tends to be significantly less elaborate, with greater emphasis on the Liturgy of the Word (the reading of the scriptures, the sermon, and the intercessory prayers). The Order for Holy Communion may be celebrated bi-weekly or monthly (in preference to the daily offices), by priests attired in choir habit, or more regular clothes, rather than Eucharistic vestments. Ceremony may be in keeping with their view of the provisions of the 17th-century Puritans – being a Reformed interpretation of the Ornaments Rubric – no candles, no incense, no bells, and a minimum of manual actions by the presiding celebrant (such as touching the elements at the Words of Institution). In recent decades, there has been a growth of charismatic worship among Anglicans. Both Anglo-Catholics and evangelicals have been affected by this movement such that it is not uncommon to find typically charismatic postures, music, and other themes evident during the services of otherwise Anglo-Catholic or evangelical parishes. The spectrum of Anglican beliefs and practice is too large to be fit into these labels. Many Anglicans locate themselves somewhere in the spectrum of the broad-church tradition and consider themselves an amalgam of evangelical and Catholic. Such Anglicans stress that Anglicanism is the via media (middle way) between the two major strains of Western Christianity and that Anglicanism is like a "bridge" between the two strains. Sacramental doctrine and practice In accord with its prevailing self-identity as a via media or "middle path" of Western Christianity, Anglican sacramental theology expresses elements in keeping with its status as being both a church in the Catholic tradition as well as a Reformed church. With respect to sacramental theology, the Catholic heritage is perhaps most strongly asserted in the importance Anglicanism places on the sacraments as a means of grace, sanctification, and salvation, as expressed in the church's liturgy and doctrine. Of the seven sacraments, all Anglicans recognise Baptism and the Eucharist as being directly instituted by Christ. The other five – Confession/Absolution, Matrimony, Confirmation, Holy Orders (also called Ordination), and Anointing of the Sick (also called Unction) – are regarded variously as full sacraments by Anglo-Catholics and many high church and some broad-church Anglicans, but merely as "sacramental rites" by other broad-church and low-church Anglicans, especially evangelicals associated with Reform UK and the Diocese of Sydney. Eucharistic theology Anglican eucharistic theology is divergent in practice, reflecting the essential comprehensiveness of the tradition. A few low-church Anglicans take a strictly memorialist (Zwinglian) view of the sacrament. In other words, they see Holy Communion as a memorial to Christ's suffering, and participation in the Eucharist as both a re-enactment of the Last Supper and a foreshadowing of the heavenly banquet – the fulfilment of the eucharistic promise. Other low-church Anglicans believe in the real presence of Christ in the Eucharist but deny that the presence of Christ is carnal or is necessarily localised in the bread and wine. Despite explicit criticism in the Thirty-Nine Articles, many high-church or Anglo-Catholic Anglicans hold, more or less, the Catholic view of the real presence as expressed in the doctrine of transubstantiation, seeing the Eucharist as a liturgical representation of Christ's atoning sacrifice with the elements actually transformed into Christ's body and blood. The majority of Anglicans, however, have in common a belief in the real presence, defined in one way or another. To that extent, they are in the company of the continental reformer Martin Luther and Calvin rather than Ulrich Zwingli. The Catechism of the American BCP of 1976 repeats the standard Anglican view ("The outward and visible sign in the Eucharist is the bread and wine"..."The inward and spiritual grace in the Holy Communion is the Body and Blood of Christ given to his people, and received by faith") without further definition. It should be remembered that Anglicanism has no official doctrine on this matter, believing it is wiser to leave the Presence a mystery. The faithful can believe privately whatever explanation they favour, be it transubstantiation, consubstantiation, receptionism, or virtualism (the two most congenial to Anglicans for centuries until the Oxford Movement), each of which espouses belief in the real presence in one way or another, or memorialism, which has never been an option with Anglicans. A famous Anglican aphorism regarding Christ's presence in the sacrament, commonly misattributed to Queen Elizabeth I, is first found in print in a poem by John Donne: He was the word that spake it, He took the bread and brake it: And what that word did make it, I do believe and take it. An Anglican position on the eucharistic sacrifice ("Sacrifice of the Mass") was expressed in the response Saepius officio of the Archbishops of Canterbury and York to Pope Leo XIII's Papal Encyclical Apostolicae curae: viz. that the Prayer Book contained a strong sacrificial theology. Later revisions of the Prayer Book influenced by the Scottish Canon of 1764 first adopted by the Protestant Episcopal Church in 1789 made this assertion quite evident: "we do make and celebrate before thy Divine Majesty with these thy holy gifts, which we now OFFER unto thee, the memorial thy Son has commanded us to make", which is repeated in the 1929 English BCP and included in such words or others such as "present" or "show forth" in subsequent revisions. Anglican and Roman Catholic representatives declared that they had "substantial agreement on the doctrine of the Eucharist" in the Windsor Statement on Eucharistic Doctrine by the Anglican-Roman Catholic International Consultation (1971) and the Elucidation of the ARCIC Windsor Statement (1979). The final response (1991) to these documents by the Vatican made it plain that it did not consider the degree of agreement reached to be satisfactory. Practices In Anglicanism, there is a distinction between liturgy, which is the formal public and communal worship of the Church, and personal prayer and devotion, which may be public or private. Liturgy is regulated by the prayer books and consists of the Holy Eucharist (some call it Holy Communion or Mass), the other six Sacraments, and the Divine Office or Liturgy of the Hours. Book of Common Prayer The Book of Common Prayer (BCP) is the foundational prayer book of Anglicanism. The original book of 1549 (revised in 1552) was one of the instruments of the English Reformation, replacing the various "uses" or rites in Latin that had been used in different parts of the country with a single compact volume in the language of the people, so that "now from henceforth all the Realm shall have but one use". Suppressed under Queen Mary I, it was revised in 1559, and then again in 1662, after the Restoration of Charles II. This version was made mandatory in England and Wales by the Act of Uniformity and was in standard use until the mid-20th century. With British colonial expansion from the 17th century onwards, Anglican churches were planted around the globe. These churches at first used and then revised the Book of Common Prayer until they, like their parent church, produced prayer books which took into account the developments in liturgical study and practice in the 19th and 20th centuries, which come under the general heading of the Liturgical Movement. Worship Anglican worship services are open to all visitors. Anglican worship originates principally in the reforms of Thomas Cranmer, who aimed to create a set order of service like that of the pre-Reformation church but less complex in its seasonal variety and said in English rather than Latin. This use of a set order of service is not unlike the Catholic tradition. Traditionally, the pattern was that laid out in the Book of Common Prayer. Although many Anglican churches now use a wide range of modern service books written in the local language, the structures of the Book of Common Prayer are largely retained. Churches which call themselves Anglican will have identified themselves so because they use some form or variant of the Book of Common Prayer in the shaping of their worship. Anglican worship, however, is as diverse as Anglican theology. A contemporary "low-church" service may differ little from the worship of many mainstream non-Anglican Protestant churches. The service is constructed around a sermon focused on Biblical exposition and opened with one or more Bible readings and closed by a series of prayers (both set and extemporised) and hymns or songs. A "high church" or Anglo-Catholic service, by contrast, is usually a more formal liturgy celebrated by clergy in distinctive vestments and may be almost indistinguishable from a Roman Catholic service, often resembling the "pre–Vatican II" Tridentine rite. Between these extremes are a variety of styles of worship, often involving a robed choir and the use of the organ to accompany the singing and to provide music before and after the service. Anglican churches tend to have pews or chairs, and it is usual for the congregation to kneel for some prayers but to stand for hymns and other parts of the service such as the Gloria, Collect, Gospel reading, Creed and either the Preface or all of the Eucharistic Prayer. Anglicans may genuflect or cross themselves in the same way as Roman Catholics. Other more traditional Anglicans tend to follow the 1662 Book of Common Prayer, and retain the use of the King James Bible. This is typical in many Anglican cathedrals and particularly in Royal Peculiars such as the Savoy Chapel and the Queen's Chapel. These services reflect older Anglican liturgies and differ from the Traditional Anglican Communion in that they are in favour of women priests and the ability of clergy to marry. These Anglican church services include classical music instead of songs, hymns from the New English Hymnal (usually excluding modern hymns such as "Lord of the Dance"), and are generally non-evangelical and formal in practice. Until the mid-20th century the main Sunday service was typically morning prayer, but the Eucharist has once again become the standard form of Sunday worship in many Anglican churches; this again is similar to Roman Catholic practice. Other common Sunday services include an early morning Eucharist without music, an abbreviated Eucharist following a service of morning prayer, and a service of evening prayer, sometimes in the form of sung Evensong, usually celebrated between 3 and 6 pm. The late-evening service of Compline was revived in parish use in the early 20th century. Many Anglican churches will also have daily morning and evening prayer, and some have midweek or even daily celebration of the Eucharist. An Anglican service (whether or not a Eucharist) will include readings from the Bible that are generally taken from a standardised lectionary, which provides for much of the Bible (and some passages from the Apocrypha) to be read out loud in the church over a cycle of one, two, or three years (depending on which eucharistic and office lectionaries are used, respectively). The sermon (or homily) is typically about ten to twenty minutes in length, often comparably short to sermons in evangelical churches. Even in the most informal Anglican services, it is common for set prayers such as the weekly Collect to be read. There are also set forms for intercessory prayer, though this is now more often extemporaneous. In high and Anglo-Catholic churches there are generally prayers for the dead. Although Anglican public worship is usually ordered according to the canonically approved services, in practice many Anglican churches use forms of service outside these norms. Liberal churches may use freely structured or experimental forms of worship, including patterns borrowed from ecumenical traditions such as those of the Taizé Community or the Iona Community. Anglo-Catholic parishes might use the modern Roman Catholic liturgy of the Mass or more traditional forms, such as the Tridentine Mass (which is translated into English in the English Missal), the Anglican Missal, or, less commonly, the Sarum Rite. Catholic devotions such as the Rosary, Angelus, and Benediction of the Blessed Sacrament are also common among Anglo-Catholics. Eucharistic discipline Only baptised persons are eligible to receive communion, although in many churches communion is restricted to those who have not only been baptised but also confirmed. In many Anglican provinces, however, all baptised Christians are now often invited to receive communion and some dioceses have regularised a system for admitting baptised young people to communion before they are confirmed. The discipline of fasting before communion is practised by some Anglicans. Most Anglican priests require the presence of at least one other person for the celebration of the Eucharist (referring back to Christ's statement in Matthew 18:20, "When two or more are gathered in my name, I will be in the midst of them."), though some Anglo-Catholic priests (like Roman Catholic priests) may say private Masses. As in the Roman Catholic Church, it is a canonical requirement to use fermented wine for communion. Unlike in Roman Catholicism, the consecrated bread and wine are always offered to the congregation at a eucharistic service ("communion in both kinds"). This practice is becoming more frequent in the Roman Catholic Church as well, especially through the Neocatechumenal Way. In some churches, the sacrament is reserved in a tabernacle or aumbry with a lighted candle or lamp nearby. In Anglican churches, only a priest or a bishop may be the celebrant at the Eucharist. Divine office All Anglican prayer books contain offices for Morning Prayer (Matins) and Evening Prayer (Evensong). In the original Book of Common Prayer, these were derived from combinations of the ancient monastic offices of Matins and Lauds; and Vespers and Compline, respectively. The prayer offices have an important place in Anglican history. Prior to the Catholic revival of the 19th century, which eventually restored the Holy Eucharist as the principal Sunday liturgy, and especially during the 18th century, a morning service combining Matins, the Litany, and ante-Communion comprised the usual expression of common worship, while Matins and Evensong were sung daily in cathedrals and some collegiate chapels. This nurtured a tradition of distinctive Anglican chant applied to the canticles and psalms used at the offices (although plainsong is often used as well). In some official and many unofficial Anglican service books, these offices are supplemented by other offices such as the Little Hours of Prime and prayer during the day such as (Terce, Sext, None, and Compline). Some Anglican monastic communities have a Daily Office based on that of the Book of Common Prayer but with additional antiphons and canticles, etc., for specific days of the week, specific psalms, etc. See, for example, Order of the Holy Cross and Order of St Helena, editors, A Monastic Breviary (Wilton, Conn.: Morehouse-Barlow, 1976). The All Saints Sisters of the Poor, with convents in Catonsville, Maryland, and elsewhere, use an elaborated version of the Anglican Daily Office. The Society of St. Francis publishes Celebrating Common Prayer, which has become especially popular for use among Anglicans. In England, the United States, Canada, Australia, New Zealand, and some other Anglican provinces, the modern prayer books contain four offices: Morning Prayer, corresponding to Matins, Lauds and Prime; Prayer During the Day, roughly corresponding to the combination of Terce, Sext, and None (Noonday Prayer in the USA); Evening Prayer, corresponding to Vespers (and Compline); Compline. In addition, most prayer books include a section of prayers and devotions for family use. In the US, these offices are further supplemented by an "Order of Worship for the Evening", a prelude to or an abbreviated form of Evensong, partly derived from Orthodox prayers. In the United Kingdom, the publication of Daily Prayer, the third volume of Common Worship, was published in 2005. It retains the services for Morning and Evening Prayer and Compline and includes a section entitled "Prayer during the Day". A New Zealand Prayer Book of 1989 provides different outlines for Matins and Evensong on each day of the week, as well as "Midday Prayer", "Night Prayer" and "Family Prayer". Some Anglicans who pray the office on daily basis use the present Divine Office of the Roman Catholic Church. In many cities, especially in England, Anglican and Roman Catholic priests and lay people often meet several times a week to pray the office in common. A small but enthusiastic minority use the Anglican Breviary, or other translations and adaptations of the pre–Vatican II Roman Rite and Sarum Rite, along with supplemental material from cognate western sources, to provide such things as a common of Octaves, a common of Holy Women, and other additional material. Others may privately use idiosyncratic forms borrowed from a wide range of Christian traditions. "Quires and Places where they sing" In the late medieval period, many English cathedrals and monasteries had established small choirs of trained lay clerks and boy choristers to perform polyphonic settings of the Mass in their Lady chapels. Although these "Lady Masses" were discontinued at the Reformation, the associated musical tradition was maintained in the Elizabethan Settlement through the establishment of choral foundations for daily singing of the Divine Office by expanded choirs of men and boys. This resulted from an explicit addition by Elizabeth herself to the injunctions accompanying the 1559 Book of Common Prayer (that had itself made no mention of choral worship) by which existing choral foundations and choir schools were instructed to be continued, and their endowments secured. Consequently, some thirty-four cathedrals, collegiate churches, and royal chapels maintained paid establishments of lay singing men and choristers in the late 16th century. All save four of these have – with interruptions during the Commonwealth and the COVID-19 pandemic – continued daily choral prayer and praise to this day. In the Offices of Matins and Evensong in the 1662 Book of Common Prayer, these choral establishments are specified as "Quires and Places where they sing". For nearly three centuries, this round of daily professional choral worship represented a tradition entirely distinct from that embodied in the intoning of Parish Clerks, and the singing of "west gallery choirs" which commonly accompanied weekly worship in English parish churches. In 1841, the rebuilt Leeds Parish Church established a surpliced choir to accompany parish services, drawing explicitly on the musical traditions of the ancient choral foundations. Over the next century, the Leeds example proved immensely popular and influential for choirs in cathedrals, parish churches, and schools throughout the Anglican communion. More or less extensively adapted, this choral tradition also became the direct inspiration for robed choirs leading congregational worship in a wide range of Christian denominations. In 1719, the cathedral choirs of Gloucester, Hereford, and Worcester combined to establish the annual Three Choirs Festival, the precursor for the multitude of summer music festivals since. By the 20th century, the choral tradition had become for many the most accessible face of worldwide Anglicanism – especially as promoted through the regular broadcasting of choral evensong by the BBC; and also in the annual televising of the festival of Nine Lessons and Carols from King's College, Cambridge. Composers closely concerned with this tradition include Edward Elgar, Ralph Vaughan Williams, Gustav Holst, Charles Villiers Stanford, and Benjamin Britten. A number of important 20th-century works by non-Anglican composers were originally commissioned for the Anglican choral tradition – for example, the Chichester Psalms of Leonard Bernstein and the Nunc dimittis of Arvo Pärt. Communion Principles of governance Contrary to popular misconception, the British monarch is not the constitutional "head" of the Church of England but is, in law, the church's "supreme governor", nor does the monarch have any role in provinces outside England. The role of the crown in the Church of England is practically limited to the appointment of bishops, including the Archbishop of Canterbury, and even this role is limited, as the church presents the government with a short list of candidates from which to choose. This process is accomplished through collaboration with and consent of ecclesial representatives (see Ecclesiastical Commissioners). Although the monarch has no constitutional role in Anglican churches in other parts of the world, the prayer books of several countries where the monarch is head of state contain prayers for him or her as sovereign. A characteristic of Anglicanism is that it has no international juridical authority. All forty-two provinces of the Anglican Communion are autonomous, each with their own primate and governing structure. These provinces may take the form of national churches (such as in Canada, Uganda or Japan) or a collection of nations (such as the West Indies, Central Africa or South Asia), or geographical regions (such as Vanuatu and Solomon Islands) etc. Within these provinces there may exist subdivisions, called ecclesiastical provinces, under the jurisdiction of a metropolitan archbishop. All provinces of the Anglican Communion consist of dioceses, each under the jurisdiction of a bishop. In the Anglican tradition, bishops must be consecrated according to the strictures of apostolic succession, which Anglicans consider one of the marks of catholicity. Apart from bishops, there are two other orders of ordained ministry: deacon and priest. No requirement is made for clerical celibacy, though many Anglo-Catholic priests have traditionally been bachelors. Because of innovations that occurred at various points after the latter half of the 20th century, women may be ordained as deacons in almost all provinces, as priests in most and as bishops in many. Anglican religious orders and communities, suppressed in England during the Reformation, have re-emerged, especially since the mid-19th century, and now have an international presence and influence. Government in the Anglican Communion is synodical, consisting of three houses of laity (usually elected parish representatives), clergy and bishops. National, provincial and diocesan synods maintain different scopes of authority, depending on their canons and constitutions. Anglicanism is not congregational in its polity: it is the diocese, not the parish church, which is the smallest unit of authority in the church. (See Episcopal polity). Archbishop of Canterbury The Archbishop of Canterbury has a precedence of honour over the other primates of the Anglican Communion, and for a province to be considered a part of the communion means specifically to be in full communion with the see of Canterbury – though this principle is currently subject to considerable debate, especially among those in the so-called Global South, including American Anglicans. The archbishop is, therefore, recognised as primus inter pares ("first amongst equals"), even though he does not exercise any direct authority in any province outside England, of which he is chief primate. Rowan Williams, the Archbishop of Canterbury from 2002 to 2012, was the first archbishop appointed from outside the Church of England since the Reformation: he was formerly the Archbishop of Wales. As "spiritual head" of the communion, the Archbishop of Canterbury maintains a certain moral authority and has the right to determine which churches will be in communion with his see. He hosts and chairs the Lambeth Conferences of Anglican Communion bishops and decides who will be invited to them. He also hosts and chairs the Anglican Communion Primates' Meeting and is responsible for the invitations to it. He acts as president of the secretariat of the Anglican Communion Office and its deliberative body, the Anglican Consultative Council. Conferences The Anglican Communion has no international juridical organisation. All international bodies are consultative and collaborative, and their resolutions are not legally binding on the autonomous provinces of the communion. There are three international bodies of note. The Lambeth Conference is the oldest international consultation. It was first convened by Archbishop Charles Longley in 1867 as a vehicle for bishops of the communion to "discuss matters of practical interest, and pronounce what we deem expedient in resolutions which may serve as safe guides to future action". Since then, it has been held roughly every ten years. Invitation is by the Archbishop of Canterbury. The Anglican Consultative Council was created by a 1968 Lambeth Conference resolution and meets biennially. The council consists of representative bishops, clergy and laity chosen by the forty-two provinces. The body has a permanent secretariat, the Anglican Communion Office, of which the Archbishop of Canterbury is president. The Anglican Communion Primates' Meeting is the most recent manifestation of international consultation and deliberation, having been first convened by Archbishop Donald Coggan in 1978 as a forum for "leisurely thought, prayer and deep consultation". Ordained ministry Like the Roman Catholic Church and the Orthodox churches, the Anglican Communion maintains the threefold ministry of deacons, presbyters (usually called "priests"), and bishops. Episcopate Bishops, who possess the fullness of Christian priesthood, are the successors of the apostles. Primates, archbishops, and metropolitans are all bishops and members of the historical episcopate who derive their authority through apostolic succession – an unbroken line of bishops that can be traced back to the 12 apostles of Jesus. Priesthood Bishops are assisted by priests and deacons. Most ordained ministers in the Anglican Communion are priests, who usually work in parishes within a diocese. Priests are in charge of the spiritual life of parishes and are usually called the rector or vicar. A curate (or, more correctly, an "assistant curate") is a priest or deacon who assists the parish priest. Non-parochial priests may earn their living by any vocation, although employment by educational institutions or charitable organisations is most common. Priests also serve as chaplains of hospitals, schools, prisons, and in the armed forces. An archdeacon is a priest or deacon responsible for administration of an archdeaconry, which is often the name given to the principal subdivisions of a diocese. An archdeacon represents the diocesan bishop in his or her archdeaconry. In the Church of England, the position of archdeacon can only be held by someone in priestly orders who has been ordained for at least six years. In some other parts of the Anglican Communion, the position can also be held by deacons. In parts of the Anglican Communion where women cannot be ordained as priests or bishops but can be ordained as deacons, the position of archdeacon is effectively the most senior office to which an ordained woman can be appointed. A dean is a priest who is the principal cleric of a cathedral or other collegiate church and the head of the chapter of canons. If the cathedral or collegiate church has its own parish, the dean is usually also rector of the parish. However, in the Church of Ireland, the roles are often separated, and most cathedrals in the Church of England do not have associated parishes. In the Church in Wales, however, most cathedrals are parish churches and their deans are now also vicars of their parishes. The Anglican Communion recognises Roman Catholic and Eastern Orthodox ordinations as valid. Outside the Anglican Communion, Anglican ordinations (at least of male priests) are recognised by the Old Catholic Church, Porvoo Communion Lutherans, and various Independent Catholic churches. Diaconate In Anglican churches, deacons often work directly in ministry to the marginalised inside and outside the church: the poor, the sick, the hungry, the imprisoned. Unlike Orthodox and most Roman Catholic deacons who may be married only before ordination, deacons are permitted to marry freely both before and after ordination, as are priests. Most deacons are preparing for priesthood and usually only remain as deacons for about a year before being ordained priests. However, there are some deacons who remain so. Many provinces of the Anglican Communion ordain both men and women as deacons. Many of those provinces that ordain women to the priesthood previously allowed them to be ordained only to the diaconate. The effect of this was the creation of a large and overwhelmingly female diaconate for a time, as most men proceeded to be ordained priest after a short time as a deacon. Deacons, in some dioceses, can be granted licences to solemnise matrimony, usually under the instruction of their parish priest and bishop. They sometimes officiate at Benediction of the Blessed Sacrament in churches which have this service. Deacons are not permitted to preside at the Eucharist (but can lead worship with the distribution of already consecrated communion where this is permitted), absolve sins, or pronounce a blessing. It is the prohibition against deacons pronouncing blessings that leads some to believe that deacons cannot solemnise matrimony. Laity All baptised members of the church are called Christian faithful, truly equal in dignity and in the work to build the church. Some non-ordained people also have a formal public ministry, often on a full-time and long-term basis – such as lay readers (also known as readers), churchwardens, vergers, and sextons. Other lay positions include acolytes (male or female, often children), lay eucharistic ministers (also known as chalice bearers), and lay eucharistic visitors (who deliver consecrated bread and wine to "shut-ins" or members of the parish who are unable to leave home or hospital to attend the Eucharist). Lay people also serve on the parish altar guild (preparing the altar and caring for its candles, linens, flowers, etc.), in the choir and as cantors, as ushers and greeters, and on the church council (called the "vestry" in some countries), which is the governing body of a parish. Religious orders A small yet influential aspect of Anglicanism is its religious orders and communities. Shortly after the beginning of the Catholic Revival in the Church of England, there was a renewal of interest in re-establishing religious and monastic orders and communities. One of Henry VIII's earliest acts was their dissolution and seizure of their assets. In 1841, Marian Rebecca Hughes became the first woman to take the vows of religion in communion with the Province of Canterbury since the Reformation. In 1848, Priscilla Lydia Sellon became the superior of the Society of the Most Holy Trinity at Devonport, Plymouth, the first organised religious order. Sellon is called "the restorer, after three centuries, of the religious life in the Church of England". For the next one hundred years, religious orders for both men and women proliferated throughout the world, becoming a numerically small but disproportionately influential feature of global Anglicanism. Anglican religious life at one time boasted hundreds of orders and communities, and thousands of religious. An important aspect of Anglican religious life is that most communities of both men and women lived their lives consecrated to God under the vows of poverty, chastity, and obedience (or, in Benedictine communities, Stability, Conversion of Life, and Obedience) by practising a mixed life of reciting the full eight services of the Breviary in choir, along with a daily Eucharist, plus service to the poor. The mixed life, combining aspects of the contemplative orders and the active orders, remains to this day a hallmark of Anglican religious life. Another distinctive feature of Anglican religious life is the existence of some mixed-gender communities. Since the 1960s, there has been a sharp decline in the number of professed religious in most parts of the Anglican Communion, especially in North America, Europe, and Australia. Many once large and international communities have been reduced to a single convent or monastery with memberships of elderly men or women. In the last few decades of the 20th century, novices have for most communities been few and far between. Some orders and communities have already become extinct. There are, however, still thousands of Anglican religious working today in approximately 200 communities around the world, and religious life in many parts of the Communion – especially in developing nations – flourishes. The most significant growth has been in the Melanesian countries of the Solomon Islands, Vanuatu, and Papua New Guinea. The Melanesian Brotherhood, founded at Tabalia, Guadalcanal, in 1925 by Ini Kopuria, is now the largest Anglican Community in the world, with over 450 brothers in the Solomon Islands, Vanuatu, Papua New Guinea, the Philippines, and the United Kingdom. The Sisters of the Church, started by Mother Emily Ayckbowm in England in 1870, has more sisters in the Solomons than all their other communities. The Community of the Sisters of Melanesia, started in 1980 by Sister Nesta Tiboe, is a growing community of women throughout the Solomon Islands. The Society of Saint Francis, founded as a union of various Franciscan orders in the 1920s, has experienced great growth in the Solomon Islands. Other communities of religious have been started by Anglicans in Papua New Guinea and in Vanuatu. Most Melanesian Anglican religious are in their early to mid-20s – vows may be temporary and it is generally assumed that brothers, at least, will leave and marry in due course – making the average age 40 to 50 years younger than their brothers and sisters in other countries. Growth of religious orders, especially for women, is marked in certain parts of Africa. Worldwide distribution Anglicanism represents the third largest Christian communion in the world, after the Roman Catholic Church and the Eastern Orthodox Church. The number of Anglicans in the world is over 85 million . The 11 provinces in Africa saw growth in the last two decades. They now include 36.7 million members, more Anglicans than there are in England. England remains the largest single Anglican province, with 26 million members. In most industrialised countries, church attendance has decreased since the 19th century. Anglicanism's presence in the rest of the world is due to large-scale emigration, the establishment of expatriate communities, or the work of missionaries. The Church of England has been a church of missionaries since the 17th century, when the Church first left English shores with colonists who founded what would become the United States, Australia, Canada, New Zealand, and South Africa, and established Anglican churches. For example, an Anglican chaplain, Robert Wolfall, with Martin Frobisher's Arctic expedition, celebrated the Eucharist in 1578 in Frobisher Bay. The first Anglican church in the Americas was built at Jamestown, Virginia, in 1607. By the 18th century, missionaries worked to establish Anglican churches in Asia, Africa, and Latin America. The great Church of England missionary societies were founded; for example, the Society for Promoting Christian Knowledge (SPCK) in 1698, the Society for the Propagation of the Gospel in Foreign Parts (SPG) in 1701, and the Church Mission Society (CMS) in 1799. The 19th century saw the founding and expansion of social-oriented evangelism with societies such as the Church Pastoral Aid Society (CPAS) in 1836, Mission to Seafarers in 1856, Girls' Friendly Society (GFS) in 1875, Mothers' Union in 1876, and Church Army in 1882, all carrying out a personal form of evangelism. The 20th century saw the Church of England developing new forms of evangelism such as the Alpha course in 1990, which was developed and propagated from Holy Trinity Brompton Church in London. In the 21st century, there has been renewed effort to reach children and youth. Fresh expressions is a Church of England missionary initiative to youth begun in 2005, and has ministries at a skate park through the efforts of St George's Church, Benfleet, Essex – Diocese of Chelmsford – or youth groups with evocative names, like the C.L.A.W (Christ Little Angels – Whatever!) youth group at Coventry Cathedral. And for the unchurched who do not actually wish to visit a brick and mortar church, there are Internet ministries such as the Diocese of Oxford's online Anglican i-Church, which appeared on the web in 2005. Ecumenism Anglican interest in ecumenical dialogue can be traced back to the time of the Reformation and dialogues with both Orthodox and Lutheran churches in the 16th century. In the 19th century, with the rise of the Oxford Movement, there arose greater concern for reunion of the churches of "Catholic confession". This desire to work towards full communion with other denominations led to the development of the Chicago-Lambeth Quadrilateral, approved by the third Lambeth Conference of 1888. The four points (the sufficiency of scripture, the historic creeds, the two dominical sacraments, and the historic episcopate) were proposed as a basis for discussion, although they have frequently been taken as a non-negotiable bottom-line for any form of reunion. Theological diversity Anglicanism in general has always sought a balance between the emphases of Catholicism and Protestantism, while tolerating a range of expressions of evangelicalism and ceremony. Clergy and laity from all Anglican churchmanship traditions have been active in the formation of the Continuing movement. While there are high church, broad-church and low-church Continuing Anglicans, many Continuing churches are Anglo-Catholic with highly ceremonial liturgical practices. Others belong to a more evangelical or low-church tradition and tend to support the Thirty-nine Articles and simpler worship services. Morning Prayer, for instance, is often used instead of the Holy Eucharist for Sunday worship services, although this is not necessarily true of all low-church parishes. Most Continuing churches in the United States reject the 1979 revision of the Book of Common Prayer by the Episcopal Church and use the 1928 version for their services instead. In addition, Anglo-Catholic bodies may use the Anglican Missal, Anglican Service Book or English Missal when celebrating Mass. Internal conflict A changing focus on social issues after the Second World War led to Lambeth Conference resolutions countenancing contraception and the remarriage of divorced persons. Eventually, most provinces approved the ordination of women. In more recent years, some jurisdictions have permitted the ordination of people in same-sex relationships and authorised rites for the blessing of same-sex unions (see Homosexuality and Anglicanism). "The more liberal provinces that are open to changing Church doctrine on marriage in order to allow for same-sex unions include Brazil, Canada, New Zealand, Scotland, South India, South Africa, the US and Wales," while the more conservative provinces are primarily located in the Global South. The lack of social consensus among and within provinces of diverse cultural traditions has resulted in considerable conflict and even schism concerning some or all of these developments (see Anglican realignment). More conservative elements within and outside of Anglicanism (primarily African churches and factions within North American Anglicanism) have opposed these changes, while some liberal and moderate Anglicans see this opposition as representing a new fundamentalism within Anglicanism and "believe a split is inevitable and preferable to continued infighting and paralysis." Some Anglicans opposed to various liberalising changes, in particular the ordination of women, have become Roman Catholics or Orthodox. Others have, at various times, joined the Continuing Anglican movement. Continuum The term "Continuing Anglicanism" refers to a number of church bodies which have formed outside of the Anglican Communion in the belief that traditional forms of Anglican faith, worship, and order have been unacceptably revised or abandoned within some Anglican Communion churches in recent decades. They therefore claim that they are "continuing" traditional Anglicanism. The modern Continuing Anglican movement principally dates to the Congress of St. Louis, held in the United States in 1977, where participants rejected changes that had been made in the Episcopal Church's Book of Common Prayer and also the Episcopal Church's approval of the ordination of women to the priesthood. More recent changes in the North American churches of the Anglican Communion, such as the introduction of same-sex marriage rites and the ordination of gay and lesbian people to the priesthood and episcopate, have created further separations. Continuing churches have generally been formed by people who have left the Anglican Communion. The original Anglican churches are charged by the Continuing Anglicans with being greatly compromised by secular cultural standards and liberal theology. Many Continuing Anglicans believe that the faith of some churches in communion with the Archbishop of Canterbury has become unorthodox and therefore have not sought to also be in communion with him. The original continuing parishes in the United States were found mainly in metropolitan areas. Since the late 1990s, a number have appeared in smaller communities, often as a result of a division in the town's existing Episcopal churches. The 2007–08 Directory of Traditional Anglican and Episcopal Parishes, published by the Fellowship of Concerned Churchmen, contained information on over 900 parishes affiliated with either the Continuing Anglican churches or the Anglican realignment movement, a more recent wave of Anglicans withdrawing from the Anglican Communion's North American provinces. Social activism A concern for social justice can be traced to very early Anglican beliefs, relating to an intertwined theology of God, nature, and humanity. The Anglican theologian Richard Hooker wrote in his book The Works of that Learned and Judicious Divine that "God hath created nothing simply for itself, but each thing in all things, and of every thing each part in other have such interest, that in the whole world nothing is found whereunto any thing created can say, 'I need thee not.'" Such statements demonstrate a theological Anglican interest in social activism, which has historically appeared in movements such as evangelical Anglican William Wilberforce's campaign against slavery in the 18th century, or 19th century issues concerning industrialisation. Working conditions and Christian socialism Lord Shaftesbury, a devout evangelical, campaigned to improve the conditions in factories, in mines, for chimney sweeps, and for the education of the very poor. For years, he was chairman of the Ragged School Board. Frederick Denison Maurice was a leading figure advocating reform, founding so-called "producer's co-operatives" and the Working Men's College. His work was instrumental in the establishment of the Christian socialist movement, although he himself was not in any real sense a socialist but "a Tory paternalist with the unusual desire to theories his acceptance of the traditional obligation to help the poor", influenced Anglo-Catholics such as Charles Gore, who wrote that "the principle of the incarnation is denied unless the Christian spirit can be allowed to concern itself with everything that interests and touches human life." Anglican focus on labour issues culminated in the work of William Temple in the 1930s and 1940s." Pacifism A question of whether or not Christianity is a pacifist religion has remained a matter of debate for Anglicans. The leading Anglican spokesman for pacifist ideas, from 1914 to 1945, was Ernest Barnes, bishop of Birmingham from 1924 to 1953. He opposed both world wars. In 1937, the Anglican Pacifist Fellowship emerged as a distinct reform organisation, seeking to make pacifism a clearly defined part of Anglican theology. The group rapidly gained popularity amongst Anglican intellectuals, including Vera Brittain, Evelyn Underhill, and the former British political leader George Lansbury. Furthermore, Dick Sheppard, who during the 1930s was one of Britain's most famous Anglican priests due to his landmark sermon broadcasts for BBC Radio, founded the Peace Pledge Union, a secular pacifist organisation for the non-religious that gained considerable support throughout the 1930s. Whilst never actively endorsed by Anglican churches, many Anglicans unofficially have adopted the Augustinian "Just War" doctrine. The Anglican Pacifist Fellowship remains highly active throughout the Anglican world. It rejects this doctrine of "just war" and seeks to reform the Church by reintroducing the pacifism inherent in the beliefs of many of the earliest Christians and present in their interpretation of Christ's Sermon on the Mount. The principles of the Anglican Pacifist Fellowship are often formulated as a statement of belief that "Jesus' teaching is incompatible with the waging of war ... that a Christian church should never support or justify war ... [and] that our Christian witness should include opposing the waging or justifying of war." Confusing the matter was the fact that the 37th Article of Religion in the Book of Common Prayer states that "it is lawful for Christian men, at the commandment of the Magistrate, to wear weapons, and serve in the wars." Therefore, the Lambeth Council in the modern era has sought to provide a clearer position by repudiating modern war and developed a statement that has been affirmed at each subsequent meeting of the council. This statement was strongly reasserted when "the 67th General Convention of the Episcopal Church reaffirms the statement made by the Anglican Bishops assembled at Lambeth in 1978 and adopted by the 66th General Convention of the Episcopal Church in 1979, calling "Christian people everywhere ... to engage themselves in non-violent action for justice and peace and to support others so engaged, recognising that such action will be controversial and may be personally very costly... this General Convention, in obedience to this call, urges all members of this Church to support by prayer and by such other means as they deem appropriate, those who engaged in such non-violent action, and particularly those who suffer for conscience' sake as a result; and be it further Resolved, that this General Convention calls upon all members of this Church seriously to consider the implications for their own lives of this call to resist war and work for peace for their own lives." After World War II The focus on other social issues became increasingly diffuse after the Second World War. On the one hand, the growing independence and strength of Anglican churches in the Global South brought new emphasis to issues of global poverty, the inequitable distribution of resources, and the lingering effects of colonialism. In this regard, figures such as Desmond Tutu and Ted Scott were instrumental in mobilising Anglicans worldwide against the apartheid policies of South Africa. Rapid social change in the industrialised world during the 20th century compelled the church to examine issues of gender, sexuality, and marriage. Ordinariates within the Roman Catholic Church On 4 November 2009, Pope Benedict XVI issued an apostolic constitution, Anglicanorum Coetibus, to allow groups of former Anglicans to enter into full communion with the Roman Catholic Church as members of personal ordinariates. 20 October 2009 announcement of the imminent constitution mentioned: Pope Benedict XVI approved, within the apostolic constitution, a canonical structure that provides for personal ordinariates which will allow former Anglicans to enter full communion with the Roman Catholic Church while preserving elements of distinctive Anglican spiritual patrimony. For each personal ordinariate, the ordinary may be a former Anglican bishop or priest. It was expected that provision would be made to allow the retention of aspects of Anglican liturgy.

Anguilla

Anguilla ( ) is a British Overseas Territory in the Caribbean. It is one of the most northerly of the Leeward Islands in the Lesser Antilles, lying east of Puerto Rico and the Virgin Islands and directly north of Saint Martin. The territory consists of the main island of Anguilla, approximately long by wide at its widest point, together with a number of much smaller islands and cays with no permanent population. The territory's capital is The Valley. The total land area of the territory is , with a population of approximately (). Etymology The native Arawak name for the island was Malliouhana. In reference to the island's shape, the Italian , meaning "eel" (in turn, from the Latin diminutive of anguis, "snake") was used as its name. History Anguilla was first settled by Indigenous Amerindian peoples who migrated from South America. The earliest Native American artefacts found on Anguilla have been dated to around 1300 BC; remains of settlements date from AD 600. There are two known petroglyph sites in Anguilla: Big Spring and Fountain Cavern. The rock ledges of Big Spring contain over 100 petroglyphs (dating back to AD 600-1200), the majority consisting of three indentations that form faces. Precisely when Anguilla was first seen by Europeans is uncertain: some sources claim that Columbus sighted the island during his second voyage in 1493, while others state that the first European explorer was the French Huguenot nobleman and merchant René Goulaine de Laudonnière in 1564. The Dutch West India Company established a fort on the island in 1631. However, the Company later withdrew after its fort was destroyed by the Spanish in 1633. Traditional accounts state that Anguilla was first colonised by English settlers from Saint Kitts beginning in 1650. The settlers focused on planting tobacco, and to a lesser extent cotton. The French temporarily took over the island in 1666 but returned it to English control under the terms of the Treaty of Breda the next year. Major John Scott who visited in September 1667, wrote of leaving the island "in good condition" and noted that in July 1668, "200 or 300 people fled thither in time of war". The French attacked again in 1688, 1745 and 1798, causing much destruction but failing to capture the island. It is likely that the early European settlers brought enslaved Africans with them. Historians confirm that African slaves lived in the region in the early 17th century, such as slaves from Senegal living on St Kitts in the mid-1600s. By 1672 a slave depot existed on the island of Nevis, serving the Leeward Islands. While the time of African arrival in Anguilla is difficult to place precisely, archival evidence indicates a substantial African presence of at least 100 enslaved people by 1683; these seem to have come from Central Africa as well as West Africa. The slaves were forced to work on the sugar plantations which had begun to replace tobacco as Anguilla's main crop. Over time the African slaves and their descendants came to vastly outnumber the white settlers. The African slave trade was eventually terminated within the British Empire in 1807, and slavery outlawed completely in 1834. Many planters subsequently sold up or left the island. During the early colonial period, Anguilla was administered by the British through Antigua; in 1825, it was placed under the administrative control of nearby Saint Kitts. Anguilla was federated with St Kitts and Nevis in 1882, against the wishes of many Anguillans. Economic stagnation, and the severe effects of several droughts in the 1890s and later the Great Depression of the 1930s led many Anguillans to emigrate for better prospects elsewhere. Full adult suffrage was introduced to Anguilla in 1952. After a brief period as part of the West Indies Federation (1958–62), the island of Anguilla became part of the associated state of Saint Kitts-Nevis-Anguilla with full internal autonomy in 1967. However many Anguillans had no wish to be a part of this union, and resented the dominance of St Kitts within it. On 30 May 1967 Anguillans forcibly ejected the St Kitts police force from the island and declared their separation from St Kitts following a referendum. The events, led by Atlin Harrigan and Ronald Webster among others, became known as the Anguillan Revolution; its goal was not independence per se, but rather independence from Saint Kitts and Nevis and a return to being a British colony. With negotiations failing to break the deadlock, a second referendum confirming Anguillans' desire for separation from St Kitts was held and the Republic of Anguilla was declared unilaterally, with Ronald Webster as president. Efforts by British envoy William Whitlock failed to break the impasse and 300 British troops were subsequently sent in March 1969. British authority was restored, and confirmed by the Anguilla Act of July 1971. In 1980, Anguilla was finally allowed to formally secede from Saint Kitts and Nevis and become a separate British Crown colony (now a British overseas territory). Since then, Anguilla has been politically stable, and has seen a large growth in its tourism and offshore financing sectors. Geography and geology Anguilla is a flat, low-lying island of coral and limestone in the Caribbean Sea, measuring some 16 miles (26 km) long and 3.5 miles (6 km) in width. It lies to the east of Puerto Rico and the Virgin Islands and directly north of Saint Martin, separated from that island by the Anguilla Channel. The soil is generally thin and poor, supporting scrub, tropical and forest vegetation. The terrain is generally low-lying, with the highest terrain located in the vicinity of The Valley; Crocus Hill, Anguilla's highest peak at , lies in the western regions of the town. Anguilla is noted for its ecologically important coral reefs and beaches. Apart from the main island of Anguilla itself, the territory includes a number of other smaller islands and cays, mostly tiny and uninhabited: Anguillita Blowing Rock Dog Island Little Scrub Island Prickly Pear Cays Scrub Island Seal Island Sombrero, also known as Hat Island Sandy Island Scilly Cay Geology Anguilla (and the wider Anguilla Bank) is of volcanic origin, lying on the Lesser Antilles volcanic island arc, and tuffs and volcaniclastic breccias of Eocene age are exposed locally on the island. The island was largely submerged during the Miocene, leading to the formation of the reefal limestone Anguilla Formation, which was subsequently tectonically uplifted and cover most of the island today. Since the late Pleistocene, however, Anguilla has undergone tectonic subsidence at a rate of around 1-2mm/yr. Climate Temperature Northeastern trade winds keep this tropical island relatively cool and dry. Average annual temperature is . July–October is its hottest period, December–February, its coolest. Rainfall Rainfall averages annually, although the figures vary from season to season and year to year. The island is subject to both sudden tropical storms and hurricanes, which occur in the period from July to November. The island suffered damage in 1995 from Hurricane Luis and severe flooding from Hurricane Lenny in 1999. Governance Political system Anguilla is an internally self-governing overseas territory of the United Kingdom. Its politics take place in a framework of a parliamentary representative democratic dependency, whereby the Premier is the head of government, and of a pluriform multi-party system. The United Nations Committee on Decolonization includes Anguilla on the United Nations list of non-self-governing territories. The territory's constitution is the Anguilla Constitutional Order 1 April 1982 (amended 1990). Executive power is exercised by the government, with legislative power being vested in both the government and the House of Assembly. The judiciary is independent of the executive and the legislature. Defence As a British overseas territory, the UK is responsible for Anguilla's military defence, although there are no active garrisons or armed forces present in the territory. Since 2020, the Royal Navy has forward-deployed the offshore patrol vessel HMS Medway long-term to the Caribbean for patrol and sovereignty protection duties. Anguilla had a small marine police force, comprising around 32 personnel, which operated one VT Halmatic M160-class 52-foot fast patrol boat. Policing on the island is the responsibility of the Royal Anguilla Police Force. Population Demographics The majority of residents (90.08%) are black, most of whom are the descendants of enslaved people transported from Africa. Minorities include whites at 3.74% and people of mixed race at 4.65% (figures from 2001 census). 72% of the population is Anguillan while 28% is non-Anguillan (2001 census). Of the non-Anguillan population, many are citizens of the United States, United Kingdom, St Kitts & Nevis, the Dominican Republic, Jamaica and Nigeria. 2006 and 2007 saw an influx of large numbers of Chinese, Indian and Mexican workers, brought in as labour for major tourist developments due to the local population not being large enough to support the labour requirements. Religion Christian churches did not have a consistent or strong presence during the initial period of English colonisation; spiritual and religious practices of Europeans and Africans tended to reflect their regional origins. As early as 1813, Christian ministers formally ministered to enslaved Africans and promoted literacy among converts. The Wesleyan (Methodist) Missionary Society of England built churches and schools from 1817. According to the 2001 census, Christianity is Anguilla's predominant religion, with 29% of the population practising Anglicanism; another 23.9% are Methodist. Other churches on the island include Seventh-day Adventist, Baptist, Roman Catholic (served by the Diocese of Saint John's–Basseterre, with the See at Saint John on Antigua and Barbuda) and a small community of Jehovah's Witnesses (0.7%). Between 1992 and 2001, the number of followers of the Church of God and Pentecostals increased considerably. There are at least 15 churches on the island. Although a minority on the island, Anguilla is an important location to followers of Rastafarian religion as the birthplace of Robert Athlyi Rogers, author of the Holy Piby which had a strong influence on Rastafarian and other Africa-centre belief systems. More recently, a Muslim cultural centre has opened on the island. Languages Today most people in Anguilla speak a British-influenced variety of standard English. Other languages are also spoken on the island, including varieties of Spanish, Chinese and the languages of other immigrant communities. However, the most common language other than Standard English is the island's own English-lexifier Creole language (not to be confused with Antillean Creole ('French Creole'), spoken in French islands such as Martinique and Guadeloupe). It is referred to locally by terms such as "dialect" (pronounced "dialek"), Anguilla Talk or "Anguillian". It has its main roots in early varieties of English and West African languages, and is similar to the dialects spoken in English-speaking islands throughout the Eastern Caribbean in terms of its structural features. Linguists who are interested in the origins of Anguillan and other Caribbean Creoles point out that some of its grammatical features can be traced to African languages while others can be traced to European languages. Three areas have been identified as significant for the identification of the linguistic origins of those forced migrants who arrived before 1710: the Gold Coast, the Slave Coast and the Windward Coast. Sociohistorical information from Anguilla's archives suggest that Africans and Europeans formed two distinct, but perhaps overlapping speech communities in the early phases of the island's colonisation. "Anguillian" is believed to have emerged as the language of the masses as time passed, slavery was abolished and locals began to see themselves as "belonging" to Anguillan society. Education There are six government primary schools, one government secondary school (Albena Lake Hodge Comprehensive School), and two private schools. There is a single library, the Edison L. Hughes Education & Library Complex of the Anguilla Public Library. A branch of the Saint James School of Medicine was established in 2011 in Anguilla. It is a private, for-profit medical school headquartered in Park Ridge, Illinois. There is a University of the West Indies Open campus site in the island. Culture The island's cultural history begins with the native Taino, Arawak and Carib. Their artefacts have been found around the island, telling of life before European settlers arrived. The Anguilla National Trust (ANT) was established in 1989 and opened its current office in 1991 charged with the responsibility of preserving the heritage of the island, including its cultural heritage. As throughout the Caribbean, holidays are a cultural fixture. Anguilla's most important holidays are of historic as much as cultural importance – particularly the anniversary of the emancipation (previously August Monday in the Park), celebrated as the Summer Festival, or Carnival. British festivities, such as the King's Birthday, are also celebrated. Cuisine Anguillan cuisine is influenced by native Caribbean, African, Spanish, French, and English cuisines. Seafood is abundant, including prawns, shrimp, crab, spiny lobster, conch, mahi-mahi, red snapper, marlin, and grouper. Salt cod is a staple food eaten on its own and used in stews, casseroles and soups. Livestock is limited due to the small size of the island and people there use poultry, pork, goat, and mutton, along with imported beef. Goat is the most commonly eaten meat, used in a variety of dishes. The official national food of Anguilla is pigeon peas and rice. A significant amount of the island's produce is imported due to limited land suitable for agriculture production; much of the soil is sandy and infertile. The agriculture produce of Anguilla includes tomatoes, peppers, limes and other citrus fruits, onion, garlic, squash, pigeon peas, and callaloo. Starch staple foods include imported rice and other foods that are imported or locally grown, including yams, sweet potatoes and breadfruit. Literature The Anguilla National Trust has programmes encouraging Anguillan writers and the preservation of the island's history. In 2015, Where I See The Sun – Contemporary Poetry in Anguilla A New Anthology by Lasana M. Sekou was published by House of Nehesi Publishers. Among the forty three poets in the collection are Rita Celestine-Carty, Bankie Banx, John T. Harrigan, Patricia J. Adams, Fabian Fahie, Dr. Oluwakemi Linda Banks, and Reuel Ben Lewi. Music Various Caribbean musical genres are popular on the island, such as reggae, soca and calypso. Sports Boat racing has deep roots in Anguillan culture and is the national sport. There are regular sailing regattas on national holidays, such as Carnival, which are contested by locally built and designed boats. These boats have names and have sponsors that print their logo on their sails. As in many other former British colonies, cricket is also a popular sport. Anguilla is the home of Omari Banks, who played for the West Indies Cricket Team, while Cardigan Connor played first-class cricket for English county side Hampshire and was 'chef de mission' (team manager) for Anguilla's Commonwealth Games team in 2002. Other noted players include Chesney Hughes, who played for Derbyshire County Cricket Club in England. Rugby union is represented in Anguilla by the Anguilla Eels RFC, who were formed in April 2006. The Eels have been finalists in the St. Martin tournament in November 2006 and semi-finalists in 2007, 2008, 2009 and Champions in 2010. The Eels were formed in 2006 by Scottish club national second row Martin Welsh, Club Sponsor and President of the AERFC Ms. Jacquie Ruan, and Canadian standout Scrumhalf Mark Harris (Toronto Scottish RFC). Anguilla is the birthplace of sprinter Zharnel Hughes who has represented Great Britain since 2015, and England at the 2018 Commonwealth Games. He won the 100 metres at the 2018 European Athletics Championships, the 4 x 100 metres at the same championships, and the 4 x 100 metres for England at the 2018 Commonwealth Games. He also won a relay team gold at the 2022 Birmingham Commonwealth Games and a silver on the relay for Great Britain at the 2020 Olympic Games. Shara Proctor, British Long Jump Silver Medalist in World Championships in Beijing first represented Anguilla in the event until 2010 when she began to represent Great Britain and England. Under the Anguillan Flag she achieved several medals in the NACAC games. Keith Connor, triple jumper, is also an Anguillan. He represented Great Britain and England and achieved several international titles including Commonwealth and European Games gold medals and an Olympic bronze medal. Keith later became Head Coach of Australia Athletics. Natural history Wildlife Anguilla has habitat for the Cuban tree frogs (Osteopilus septentrionalis). The red-footed tortoise (Chelonoidis carbonaria) is a species of tortoise found here, which originally came from South America. Hurricanes in the mid-90s led to over-water dispersal of the green iguanas (Iguana iguana) to Anguilla. All three animals are introductions. Five species of bats are known in the literature from Anguilla – the threatened insular single leaf bat (Monophyllus plethodon), the Antillean fruit-eating bat (Brachyphylla cavernarum), the Jamaican fruit bat (Artibeus jamaicensis), the Mexican funnel-eared bat (Natalus stramineus), and the velvety free-tailed bat (Molossus molossus). Notable people Kelvin Liddie (born 1981), Anguillan football player Carlos Newton, former UFC Welterweight Champion Shara Proctor, longjump athlete Zharnel Hughes , sprinter Economy Anguilla's thin arid soil being largely unsuitable for agriculture, the island has few land-based natural resources. Its main industries are tourism, offshore incorporation and management, offshore banking, captive insurance and fishing. Anguilla's currency is the East Caribbean dollar, though the US dollar is also widely accepted. The exchange rate is fixed to the US dollar at US$1 = EC$2.70. The economy, and especially the tourism sector, suffered a setback in late 1995 due to the effects of Hurricane Luis in September. Hotels were hit particularly hard but a recovery occurred the following year. Another economic setback occurred during the aftermath of Hurricane Lenny in 2000. Before the 2008 worldwide crisis, the economy of Anguilla was growing strongly, especially the tourism sector, which was driving major new developments in partnerships with multi-national companies. Anguilla's tourism industry received a major boost when it was selected to host the World Travel Awards in December 2014. Known as "the Oscars of the travel industry", the awards ceremony was held at the CuisinArt Resort and Spa and was hosted by Vivica A. Fox. Anguilla was voted the World's Leading Luxury Island Destination from a short list of top-tier candidates such as St. Barts, the Maldives, and Mauritius. Anguilla's financial system comprises seven banks, two money services businesses, more than 40 company managers, more than 50 insurers, 12 brokers, more than 250 captive intermediaries, more than 50 mutual funds, and eight trust companies. Anguilla has become a popular tax haven, having no capital gains, estate, profit, sales, or corporate taxes. In April 2011, faced with a mounting deficit, it introduced a 3% "Interim Stabilisation Levy", Anguilla's first form of income tax. Anguilla also has a 0.75% property tax. Anguilla aims to obtain 15% of its energy from solar power to become less reliant on expensive imported diesel. The Climate & Development Knowledge Network is helping the government gather the information it needs to change the territory's legislation, so that it can integrate renewables into its grid. Barbados has also made good progress in switching to renewables, but many other Small Island Developing States are still at the early stages of planning how to integrate renewable energy into their grids. "For a small island we're very far ahead," said Beth Barry, Coordinator of the Anguilla Renewable Energy Office. "We've got an Energy Policy and a draft Climate Change policy and have been focusing efforts on the question of sustainable energy supply for several years now. As a result, we have a lot of information we can share with other islands." Transportation Air Anguilla is served by Clayton J. Lloyd International Airport (prior to 4 July 2010 known as Wallblake Airport). The primary runway at the airport is in length and can accommodate moderate-sized aircraft. Regional scheduled passenger services connect to various other Caribbean islands via local airlines. In December 2021 Anguilla inaugurated its first ever international regular commercial jet service flight to and from the mainland U.S. American Eagle operating on behalf of American Airlines began nonstop Embraer 175 regional jet service to Anguilla from Miami in an aviation watershed moment for Anguilla with the airport also currently attempting to attract other international air carriers. Other airlines currently serving the airport include Tradewind Aviation and Cape Air which provide scheduled air service to San Juan, Puerto Rico. Several other small airlines serve the airport as well. The airport can handle large narrow-body jets such as the Boeing 737 and Airbus A320 and has growing private jet service flights with a new private jet terminal being built. Road Aside from taxis, there is no public transport on the island. Cars drive on the left. Boat There are regular ferries from Saint Martin to Anguilla. It is a 20-minute crossing from Marigot, St. Martin to Blowing Point, Anguilla. Ferries commence service from 7:00 am. There is also a charter service, from Blowing Point, Anguilla to Princess Juliana Airport to make travel easier. This way of travel is the most common method of transport between Anguilla and St. Martin.

Ashmore and Cartier Islands

The Territory of Ashmore and Cartier Islands is an uninhabited external territory of Australia consisting of four low-lying tropical islands in two separate reefs, and the territorial sea generated by the islands. The territory is located in the Indian Ocean situated on the edge of the continental shelf, about off the northwest coast of Australia and south of the Indonesian island of Rote. Ashmore Reef is called Pulau Pasir by Indonesians and Nusa Solokaek in the Rotenese language. Both names have the meaning "sand island". Geography The territory comprises Ashmore Reef, which includes West, Middle, and East Islands, and two lagoons, and Cartier Reef, which includes Cartier Island. Ashmore Reef covers approximately and Cartier Reef , both measurements extending to the limits of the reefs. West, Middle, and East Islands have a combined land area variously reported as , and . Cartier Island has a reported land area of . History According to Australian literature, Cartier Island was visited by Captain Nash in 1800, and named after his ship Cartier. Ashmore Island was seen by Captain Samuel Ashmore in 1811 from his ship Hibernia and named after him. Ashmore Island was annexed by the United Kingdom in 1878, as was Cartier Island in 1909. After their annexation, the British government occasionally granted licences on the islands for fishing or guano extraction. In the 1920s, the islands were used as a base for poachers targeting the Western Australian pearling industry. The lack of effective policing led to Australian lobbying for a transfer of control. A British order-in-council dated 23 July 1931 stated that Ashmore and Cartier Islands would be placed under the authority of the Commonwealth of Australia when Australia passed legislation to accept them, and formal administration began two years later. The Commonwealth's resulting Ashmore and Cartier Islands Acceptance Act 1933 came into operation on 10 May 1934, when the islands formally became a territory. The act authorised the Governor of Western Australia to make ordinances for the territory. In July 1938 the territory was annexed to the Northern Territory, then also administered by the Commonwealth, whose laws, ordinances and regulations applied to the Northern Territory. When self-government was granted to the Northern Territory on 1 July 1978, administration of Ashmore and Cartier Islands was retained by the Commonwealth. In 1983, the territory was declared a nature reserve under the National Parks and Wildlife Conservation Act 1975, now replaced by the Environment Protection and Biodiversity Conservation Act 1999. Cartier Island, which was a former bombing range, became a marine reserve in 2000. After the islands became a first point of contact with the Australian migration zone, in September 2001, the Australian government excised the Ashmore and Cartier Islands from the Australian migration zone. Indonesian heritage and memorandum Ashmore has been regularly visited and fished by Indonesian fishermen since the early eighteenth century. A 1974 Memorandum of Understanding (MOU) between Australia and Indonesia sets out arrangements by which traditional fishers can access resources in Australia's territorial sea in the region. This allows traditional Indonesian fishermen to access parts of Ashmore for shelter, freshwater and to visit grave sites. The area, known as the MOU Box, contains the Ashmore and Cartier Islands Territory. Governance Today, the territory is administered from Canberra by the Department of Infrastructure, Regional Development and Cities, which is also responsible for the administration of the territories of Christmas Island, Cocos (Keeling) Islands, the Coral Sea Islands, Jervis Bay Territory and Norfolk Island. The Attorney-General's Department had been responsible for the administration of Australian territories until the 2010 federal election. In that year the responsibility for Australian territories was transferred to the then Department of Regional Australia, Local Government, Arts and Sport, and from 18 September 2013 the Department of Infrastructure and Regional Development has administered Australian territories. Defence of Ashmore and Cartier Islands is the responsibility of Australia, with periodic visits by the Royal Australian Navy, Royal Australian Air Force and the Australia Border Force. Nearby Hibernia Reef, northeast of Ashmore Reef, is not part of the Territory, but belongs to Western Australia. It has no permanently dry land area, although large parts of the reef become exposed during low tide. Environment and protection The Ashmore Reef Marine Park and Cartier Island Marine Park are both classed as strict nature reserves (IUCN Ia) and protect biodiverse areas of significant and international importance, as well as cultural heritage. Cartier Island is an unvegetated sand island, with access prohibited because of the risk of unexploded ordnances. There are no ports or harbours, only offshore anchorage. Today, all the wells in the Territory are infected with cholera or contaminated and undrinkable. The Australian Border Force vessel is stationed off the reef for up to 300 days per year. The islands are also visited by seasonal caretakers and occasional scientific researchers. Economy The area around the Ashmore and Cartier Islands has been a traditional fishing ground of Indonesian fishermen for centuries, and continues. In the 1850s, American whalers operated in the region. Outside of fishing, the islands were historically used as sources of guano, beche-de-mer, trochus and tortoiseshell. Mining of phosphate deposits took place on Ashmore Island in the latter half of the 19th century. Petroleum extraction activities take place at the Jabiru and Challis oil fields, which are adjacent to the Territory, and which are administered by the Northern Territory's Department of Mines and Energy on behalf of the Commonwealth. Migration As Ashmore Reef is the closest point of Australian territory to Indonesia, it was a popular target for people smugglers transporting asylum seekers en route to Australia. Once they had landed on Ashmore Island, asylum seekers could claim to have entered Australian migration zone and request to be processed as refugees. The use of Ashmore Island for this purpose created great notoriety during late 2001, when refugee arrivals became a major political issue in Australia. The Australian Government argued that as Australia was not the country of first asylum for these "boat people", Australia did not have a responsibility to accept them. A number of things were done to discourage the use of the Territory for this purpose, such as attempting to have the people smugglers arrested in Indonesia; the so-called Pacific Solution of processing them in third countries; the boarding and forced turnaround of the boats by Australian military forces; and finally excising the Territory and many other small islands from the Australian migration zone. Two boatloads of asylum seekers were each detained for several days in the lagoon at Ashmore Island after failed attempts by the Royal Australian Navy to turn them back to Indonesia in October 2001.

Acoustic theory

Acoustic theory is a scientific field that relates to the description of sound waves. It derives from fluid dynamics. See acoustics for the engineering approach. For sound waves of any magnitude of a disturbance in velocity, pressure, and density we have In the case that the fluctuations in velocity, density, and pressure are small, we can approximate these as Where is the perturbed velocity of the fluid, is the pressure of the fluid at rest, is the perturbed pressure of the system as a function of space and time, is the density of the fluid at rest, and is the variance in the density of the fluid over space and time. In the case that the velocity is irrotational (), we then have the acoustic wave equation that describes the system: Where we have Derivation for a medium at rest Starting with the Continuity Equation and the Euler Equation: If we take small perturbations of a constant pressure and density: Then the equations of the system are Noting that the equilibrium pressures and densities are constant, this simplifies to A Moving Medium Starting with We can have these equations work for a moving medium by setting , where is the constant velocity that the whole fluid is moving at before being disturbed (equivalent to a moving observer) and is the fluid velocity. In this case the equations look very similar: Note that setting returns the equations at rest. Linearized Waves Starting with the above given equations of motion for a medium at rest: Let us now take to all be small quantities. In the case that we keep terms to first order, for the continuity equation, we have the term going to 0. This similarly applies for the density perturbation times the time derivative of the velocity. Moreover, the spatial components of the material derivative go to 0. We thus have, upon rearranging the equilibrium density: Next, given that our sound wave occurs in an ideal fluid, the motion is adiabatic, and then we can relate the small change in the pressure to the small change in the density by Under this condition, we see that we now have Defining the speed of sound of the system: Everything becomes For Irrotational Fluids In the case that the fluid is irrotational, that is , we can then write and thus write our equations of motion as The second equation tells us that And the use of this equation in the continuity equation tells us that This simplifies to Thus the velocity potential obeys the wave equation in the limit of small disturbances. The boundary conditions required to solve for the potential come from the fact that the velocity of the fluid must be 0 normal to the fixed surfaces of the system. Taking the time derivative of this wave equation and multiplying all sides by the unperturbed density, and then using the fact that tells us that Similarly, we saw that . Thus we can multiply the above equation appropriately and see that Thus, the velocity potential, pressure, and density all obey the wave equation. Moreover, we only need to solve one such equation to determine all other three. In particular, we have For a moving medium Again, we can derive the small-disturbance limit for sound waves in a moving medium. Again, starting with We can linearize these into For Irrotational Fluids in a Moving Medium Given that we saw that If we make the previous assumptions of the fluid being ideal and the velocity being irrotational, then we have Under these assumptions, our linearized sound equations become Importantly, since is a constant, we have , and then the second equation tells us that Or just that Now, when we use this relation with the fact that , alongside cancelling and rearranging terms, we arrive at We can write this in a familiar form as This differential equation must be solved with the appropriate boundary conditions. Note that setting returns us the wave equation. Regardless, upon solving this equation for a moving medium, we then have See also Acoustic attenuation Sound Fourier analysis References Fluid dynamics Acoustics Sound

Alexander Mackenzie (politician)

Alexander Mackenzie (January 28, 1822 – April 17, 1892) was a Canadian politician who served as the second prime minister of Canada, in office from 1873 to 1878. Mackenzie was born in Logierait, Perthshire, Scotland. He left school at the age of 13, following his father's death to help his widowed mother, and trained as a stonemason. Mackenzie immigrated to Canada when he was 19, settling in what became Ontario. His masonry business prospered, allowing him to pursue other interests – such as the editorship of a pro-Reformist newspaper called the Lambton Shield. Mackenzie was elected to the Legislative Assembly of the Province of Canada in 1862, as a supporter of George Brown. In 1867, Mackenzie was elected to the new House of Commons of Canada for the Liberal Party. He became leader of the party (thus Leader of the Opposition) in mid-1873, and a few months later succeeded John A. Macdonald as prime minister, following Macdonald's resignation in the aftermath of the Pacific Scandal. Mackenzie and the Liberals won a clear majority at the 1874 election. He was popular among the general public for his humble background and apparent democratic tendencies. As prime minister, Mackenzie continued the nation-building programme that had been begun by his predecessor. His government established the Supreme Court of Canada and Royal Military College of Canada, and created the District of Keewatin to better administer Canada's newly acquired western territories. However, it made little progress on the transcontinental railway, and struggled to deal with the aftermath of the Panic of 1873. At the 1878 election, Mackenzie's government suffered a landslide defeat. He remained leader of the Liberal Party for another two years, and continued on as a Member of Parliament (MP) until his death, due to a stroke. Early life Mackenzie was born on January 28, 1822, in Logierait, Perthshire, Scotland, the son of Mary Stewart (Fleming) and Alexander Mackenzie Sr. (born 1784) who were married in 1817. The site of his birthplace is known as Clais-'n-deoir (the Hollow of the Weeping), where families said their goodbyes as the convicted were led to nearby Gallows Hill. The house in which he was born was built by his father. He was the third of 10 boys, seven of whom survived infancy. Alexander Mackenzie Sr. was a carpenter and ship's joiner who had to move around frequently for work after the end of the Napoleonic Wars in 1815. Mackenzie's father died on March 7, 1836, and at the age of 13, Alexander Mackenzie Jr. was thus forced to end his formal education to help support his family. He apprenticed as a stonemason and met his future wife, Helen Neil, in Irvine, where her father was also a stonemason. The Neils were Baptist and shortly thereafter, Mackenzie converted from Presbyterianism to Baptist beliefs. Together with the Neils, he immigrated to Canada in 1842 to seek a better life. Mackenzie's faith was to link him to the increasingly influential temperance cause, particularly strong in Canada West where he lived, a constituency of which he was to represent in the Parliament of Canada. The Neils and Mackenzie settled in Kingston, Ontario. The limestone in the area proved too hard for his stonemason tools, and not having money to buy new tools, Mackenzie took a job as a labourer constructing a building on Princess Street. The contractor on the job claimed financial difficulty, so Mackenzie accepted a promissory note for summer wages. The note later proved to be worthless. Subsequently, Mackenzie won a contract building a bomb-proof arch at Fort Henry. He later became a foreman on the construction of Kingston's four Martello Towers – Murney Tower, Fort Frederick, Cathcart Tower, and Shoal Tower. He was also a foreman on the construction of the Welland Canal and the Lachine Canal. While working on the Beauharnois Canal, a one-ton stone fell and crushed one of his legs. He recovered, but never regained the strength in that leg. While in Kingston, Mackenzie became a vocal opponent of religious and political entitlement and corruption in government. Mackenzie married Helen Neil (1826–52) in 1845 and with her had three children, with only one girl, Mary, surviving infancy. Helen and he moved to Sarnia, Ontario (known as Canada West) in 1847 and Mary was born in 1848. They were soon joined from Scotland by the rest of Mackenzie's brothers and his mother. He began working as a general contractor, earning a reputation for being a hard-working, honest man, as well as having a working man's view on fiscal policy. Mackenzie helped construct many courthouses and jails across southern Ontario. A number of these still stand today, including the Sandwich Courthouse and Jail now known as the Mackenzie Hall Cultural Centre in Windsor, Ontario, and the Kent County Courthouse and Jail in Chatham, Ontario. He even bid, unsuccessfully, on the construction of the Parliament buildings in Ottawa in 1859. Helen died in 1852, finally succumbing to the effects of excessive doses of mercury-based calomel used to treat a fever while in Kingston. In 1853, he married Jane Sym (1825–93). Early political involvement Mackenzie involved himself in politics almost from the moment he arrived in Canada. He fought passionately for equality and the elimination of all forms of class distinction. In 1851, he became the secretary for the Reform Party for Lambton. After convincing him to run in Kent/Lambton, Mackenzie campaigned relentlessly for George Brown, owner of the Reformist paper The Globe in the 1851 election, helping Brown to win his first seat in the Legislative Assembly. Mackenzie and Brown remained the closest of friends and colleagues for the rest of their lives. In 1852, Mackenzie became editor of another reformist paper, the Lambton Shield. As an editor, Mackenzie was perhaps a little too vocal, leading the paper to a lawsuit for libel against the local conservative candidate. Because a key witness claimed Cabinet Confidence and would not testify, the paper lost the suit and was forced to fold due to financial hardship. After his brother, Hope Mackenzie, declined to run, Alexander was petitioned to run and won his first seat in the Legislative Assembly as a supporter of George Brown in 1861. When Brown resigned from the Great Coalition in 1865 over reciprocity negotiations with the United States, Mackenzie was invited to replace him as the president of the council. Wary of Macdonald's motivations and true to his principles, Mackenzie declined. He entered the House of Commons of Canada in 1867, representing the Lambton, Ontario, riding. No cohesive national Liberal Party of Canada existed at the time and with Brown not winning his seat, no official leader emerged. Mackenzie did not believe he was the best qualified for the position, and although he resisted offers of the position, he nevertheless sat as the de facto leader of the Official Opposition. Prime Minister (1873–1878) When the Macdonald government fell due to the Pacific Scandal in 1873, the Governor General, Lord Dufferin, called upon Mackenzie, who had been chosen as the leader of the Liberal Party a few months earlier, to form a new government. Mackenzie formed a government and asked the Governor General to call an election for January 1874. The Liberals won a majority of the seats in the House of Commons having garnered 40% of the popular vote. Mackenzie remained prime minister until the 1878 election when Macdonald's Conservatives returned to power with a majority government. For a man of Mackenzie's humble origins to attain such a position was unusual in an age which generally offered such opportunity only to the privileged. Lord Dufferin expressed early misgivings about a stonemason taking over government, but on meeting Mackenzie, Dufferin revised his opinions: Mackenzie served concurrently as Minister of Public Works and oversaw the completion of the Parliament buildings. While drawing up the plans for the West Block, he included a circular staircase leading directly from his office to the outside of the building, which allowed him to escape the patronage-seekers waiting for him in his ante-chamber. Proving Dufferin's reflections on his character to be true, Mackenzie disliked intensely the patronage inherent in politics. Nevertheless, he found it a necessary evil to maintain party unity and ensure the loyalty of his fellow Liberals. In keeping with his democratic ideals, Mackenzie refused the offer of a knighthood three times, and was thus the only one of Canada's first eight Prime Ministers not to be knighted. He also declined appointment to the UK Privy Council and hence does not bear the title "Right Honourable". His pride in his working class origins never left him. Once, while touring Fort Henry as prime minister, he asked the soldier accompanying him if he knew the thickness of the wall beside them. The embarrassed escort confessed that he didn't and Mackenzie replied, "I do. It is five feet, ten inches. I know, because I built it myself!" As Prime Minister, Alexander Mackenzie strove to reform and simplify the machinery of government, achieving a remarkable record of reform legislation. He introduced the secret ballot; advised the creation of the Supreme Court of Canada; the establishment of the Royal Military College of Canada in Kingston in 1874; and the creation of the Office of the Auditor General in 1878. He completed the Intercolonial Railway, but struggled to progress on the national railway due to a worldwide economic depression, almost coming to blows with the then Governor General Lord Dufferin over imperial interference. Mackenzie stood up for the rights of Canada as a nation and fought for the supremacy of Parliament and honesty in government. Above all else, he was known and loved for his honesty and integrity. However, his term was marked by economic depression that had grown out of the Panic of 1873, which Mackenzie's government was unable to alleviate. In 1874, Mackenzie negotiated a new free trade agreement with the United States, eliminating the high protective tariffs on Canadian goods in US markets. However, this action did not bolster the economy, and construction of the CPR slowed drastically due to lack of funding. In 1876, the Conservative opposition announced a National Policy of protective tariffs, which resonated with voters. When an election was held at the conclusion of Mackenzie's five-year term, the Conservatives were swept back into office in a landslide victory. Supreme Court appointments Mackenzie chose the following jurists to be appointed as justices of the Supreme Court of Canada by the Governor General: Sir William Buell Richards (Chief Justice) – September 30, 1875 Télesphore Fournier – September 30, 1875 William Alexander Henry – September 30, 1875 Sir William Johnstone Ritchie – September 30, 1875 Sir Samuel Henry Strong – September 30, 1875 Jean-Thomas Taschereau – September 30, 1875 Sir Henri Elzéar Taschereau – October 7, 1878 Later life After his government's defeat, Mackenzie remained Leader of the Opposition for another two years, until 1880. In 1881, he became the first president of The North American Life Assurance Company. He was soon struck with a mysterious ailment that sapped his strength and all but took his voice. Sitting in silence, he nevertheless remained an undefeated MP until his death in 1892 from a stroke that resulted from hitting his head during a fall. He died in Toronto and was buried in Lakeview Cemetery in Sarnia, Ontario. Character Mackenzie's first biography in 1892 referred to him as Canada's Stainless Statesman. He was a devout Baptist and teetotaller who found refuge in, and drew strength from, his family, friends, and faith. He was also a loyal friend and an incorrigible prankster (stuffed chimney on young in-laws; rolled boulder down Thunder Cape towards friend A. McKellar; burned Tory campaign placards in hotel woodstove early in morning). Unpretentious and down to earth, his public official austerity was in striking contrast to private compassion and giving nature. He was the soul of honour and integrity, a proud man who sought no recognition or personal enrichment and accepted gifts reluctantly. He preferred to follow than lead (unreferenced – many times he refused leadership offers) and often found duty outweighed heavy burden of office. He was uncompromising on his principles, perhaps too much so. An historian at the time said, "He was, and ever will remain, the Sir Galahad of Canadian politics." Very proud of his Scottish heritage, he was forever a Scot: "Nemo me impune lacessit" (no one attacks me with impunity). The Upper Canada rebellion leader W.L. Mackenzie referred to him, "He is every whit a self-made, self-educated man. Has large mental capacity and indomitable energy." Canada's Governor General, Lord Dufferin, said of him, he is "as pure as crystal, and as true as steel, with lots of common sense." A close friend, Chief Justice Sir Louis Davies, said he was "the best debater the House of Commons has ever known." A friend and colleague in Cabinet who went on to become prime minister of Canada, Sir Wilfrid Laurier, said he was "one of the truest and strongest characters to be met within Canadian history. He was endowed with a warm heart and a copious and rich fancy, though veiled by a somewhat reticent exterior, and he was of friends the most tender and true." Another friend and colleague, who went on to become premier of Ontario, Sir George Ross, said, "Mackenzie was sui generis a debater. His humorous sallies blistered like a blast from a flaming smelter. His sterling honesty is a great heritage, and will keep his memory green to all future generations." At his eulogy, Rev. Dr. Thomas compared him to the Duke of Wellington, who "stood four square, to all the winds that blow." Newspaper around the world and in Canada had this to say about him. The London Times – the untiring energy, the business-like accuracy, the keen perception and reliable judgment, and above all the inflexible integrity, which marked his private life, he carried without abatement of one jot into his public career. The Westminster Review – a man, who although, through failing health and failing voice, he had virtually passed out of public life, yet retained to the last the affectionate veneration of the Canadian people as no other man of the time can be said to have done. The Charlottetown Patriot – in all that constitutes the real man, the honest statesman, the true patriot, the warm friend, and sincere Christian, he had few equals. Possessed of a clear intellect, a retentive memory, and a ready command of appropriate words, he was one of the most logical and powerful speakers we have ever heard. The St. John Telegraph – he was loved by the people and his political opponents were compelled to respect him even above their own chosen leader. As a statesman, he has had few equals. The Montreal Star – it is one of the very foremost architects of the Canadian nationality that we mourn. In the dark days of ’73, Canadians were in a state of panic, distrusting the stability of their newly-built Dominion; no one can tell what would have happened had not the stalwart form of Alexander Mackenzie lifted itself above the screaming, vociferating and denying mass of politicians, and all Canada felt at once, there was a man who could be trusted. The Toronto Globe – he was a man who loved the people and fought for their rights against privilege and monopoly in every form. The Philadelphia Record – Like Caesar, who twice refused a knightly crown, Alexander Mackenzie refused knighthood three times. Unlike Caesar, he owed his political overthrow to his incorruptible honesty and unswerving integrity. Legacy In their 1999 study of the Prime Ministers of Canada, which included the results of a survey of Canadian historians, J. L. Granatstein and Norman Hillmer found that Mackenzie was in 11th place just after John Sparrow David Thompson.

Ashoka

Ashoka (, ; also Asoka;  – 232 BCE), popularly known as Ashoka the Great, was the third emperor of the Maurya Empire of the Indian subcontinent during to 232 BCE. His empire covered a large part of the Indian subcontinent, stretching from present-day Afghanistan in the west to present-day Bangladesh in the east, with its capital at Pataliputra. A patron of Buddhism, he is credited with playing an important role in the spread of Buddhism across ancient Asia. Much of the information about Ashoka comes from his Brahmi edicts, which are among the earliest long inscriptions of ancient India, and the Buddhist legends written centuries after his death. Ashoka was a son of Bindusara, and a grandson of the dynasty's founder Chandragupta. During his father's reign, he served as the governor of Ujjain in central India. According to some Buddhist legends, he also suppressed a revolt in Takshashila as a prince, and after his father's death, killed his brothers to ascend the throne. Ashoka's edicts state that during his eighth regnal year (), he conquered Kalinga after a brutal war, and the destruction caused by the war made him repent violence. This claim is omitted in his inscriptions found in the Kalinga region, possibly because Ashoka considered it politically inappropriate to admit his remorse before the people of Kalinga, or because the claims made in the edicts are not fully accurate and are meant to impress the people of other regions. Ashoka subsequently devoted himself to the propagation of "dhamma" or righteous conduct, the major theme of the edicts. Ashoka's edicts suggest that a few years after the Kalinga War, he was gradually drawn towards Buddhism. The Buddhist legends do not mention the Kalinga War at all, and variously state that Ashoka converted to Buddhism after being dissatisfied with the leaders of the other faiths or after witnessing miracles performed by Buddhist leaders. They credit Ashoka with establishing a large number of stupas, patronising the Third Buddhist council, supporting Buddhist missionaries, making generous donations to the sangha, and even persecuting non-Buddhists. The historicity of these legends is debated among modern historians, as they are often inconsistent with the edicts and among themselves, contain mythological elements, and exaggerate Ashoka's wickedness before and his piousness after his conversion to Buddhism. Ashoka's own edicts suggest that he favoured Buddhism, but also patronised the other major contemporary faiths including Brahmanism, Jainism, and Ājīvikaism. Ashoka's existence as a historical king had almost been forgotten, but this changed with the decipherment of the Brahmi script in the 19th century. Historians connected the titles Priyadasi and Devanampriya mentioned in his edicts to the Ashoka of Buddhist legends, and established Ashoka's reputation as one of the greatest Indian emperors. The emblem of the modern Republic of India is an adaptation of the Lion Capital of Ashoka. Sources of information Information about Ashoka comes from his inscriptions; other inscriptions that mention him or are possibly from his reign; and ancient literature, especially Buddhist texts. These sources often contradict each other, although various historians have attempted to correlate their testimony. So, for example, while Ashoka is often attributed with building many hospitals during his time, there is no clear evidence that any hospitals existed in ancient India during the 3rd century BC or that Ashoka was responsible for commissioning the construction of any. Inscriptions Ashoka's inscriptions are the earliest self-representations of imperial power in the Indian subcontinent. However, these inscriptions are focused mainly on the topic of dhamma, and provide little information regarding other aspects of the Maurya state or society. Even on the topic of dhamma, the content of these inscriptions cannot be taken at face value. In the words of American academic John S. Strong, it is sometimes helpful to think of Ashoka's messages as propaganda by a politician whose aim is to present a favourable image of himself and his administration, rather than record historical facts. A small number of other inscriptions also provide some information about Ashoka. For example, he finds a mention in the 2nd century Junagadh rock inscription of Rudradaman. An inscription discovered at Sirkap mentions a lost word beginning with "Priy", which is theorised to be Ashoka's title "Priyadarshi", although this is not certain. Some other inscriptions, such as the Sohgaura copper plate inscription, have been tentatively dated to Ashoka's period by some scholars, although others contest this. Buddhist legends Much of the information about Ashoka comes from Buddhist legends, which present him as a great, ideal king. These legends appear in texts that are not contemporary to Ashoka and were composed by Buddhist authors, who used various stories to illustrate the impact of their faith on Ashoka. This makes it necessary to exercise caution while relying on them for historical information. Among modern scholars, opinions range from downright dismissal of these legends as mythological to acceptance of all historical portions that seem plausible. The Buddhist legends about Ashoka exist in several languages, including Sanskrit, Pali, Tibetan, Chinese, Burmese, Sinhala, Thai, Lao, and Khotanese. All these legends can be traced to two primary traditions: the North Indian tradition preserved in the Sanskrit-language texts such as Divyavadana (including its constituent Ashokavadana); and Chinese sources such as A-yü wang chuan and A-yü wang ching. the Sri Lankan tradition preserved in Pali-lanuage texts, such as Dipavamsa, Mahavamsa, Vamsatthapakasini (a commentary on Mahavamsa), Buddhaghosha's commentary on the Vinaya, and Samanta-pasadika. There are several significant differences between the two traditions. For example, the Sri Lankan tradition emphasizes Ashoka's role in convening the Third Buddhist council, and his dispatch of several missionaries to distant regions, including his son Mahinda to Sri Lanka. However, the North Indian tradition makes no mention of these events. It describes other events not found in the Sri Lankan tradition, such as a story about another son named Kunala. Even while narrating the common stories, the two traditions diverge in several ways. For example, both Ashokavadana and Mahavamsa mention that Ashoka's queen Tishyarakshita had the Bodhi Tree destroyed. In Ashokavadana, the queen manages to have the tree healed after she realises her mistake. In the Mahavamsa, she permanently destroys the tree, but only after a branch of the tree has been transplanted in Sri Lanka. In another story, both the texts describe Ashoka's unsuccessful attempts to collect a relic of Gautama Buddha from Ramagrama. In Ashokavadana, he fails to do so because he cannot match the devotion of the Nagas who hold the relic; however, in the Mahavamsa, he fails to do so because the Buddha had destined the relic to be enshrined by King Dutthagamani of Sri Lanka. Using such stories, the Mahavamsa glorifies Sri Lanka as the new preserve of Buddhism. Other sources Numismatic, sculptural, and archaeological evidence supplements research on Ashoka. Ashoka's name appears in the lists of Mauryan kings in the various Puranas. However, these texts do not provide further details about him, as their Brahmanical authors were not patronised by the Mauryans. Other texts, such as the Arthashastra and Indica of Megasthenes, which provide general information about the Maurya period, can also be used to make inferences about Ashoka's reign. However, the Arthashastra is a normative text that focuses on an ideal rather than a historical state, and its dating to the Mauryan period is a subject of debate. The Indica is a lost work, and only parts of it survive in the form of paraphrases in later writings. The 12th-century text Rajatarangini mentions a Kashmiri king Ashoka of Gonandiya dynasty who built several stupas: some scholars, such as Aurel Stein, have identified this king with the Maurya king Ashoka; others, such as Ananda W. P. Guruge dismiss this identification as inaccurate. Alternative interpretation of the epigraphic evidence For some scholars, such as Christopher I. Beckwith, Ashoka, whose name only appears in the Minor Rock Edicts, is not the same as king Piyadasi, or Devanampiya Piyadasi (i.e. "Beloved of the Gods Piyadasi", "Beloved of the Gods" being a fairly widespread title for "King"), who is named as the author of the Major Pillar Edicts and the Major Rock Edicts. Beckwith suggests that Piyadasi was living in the 3rd century BCE, was probably the son of Chandragupta Maurya known to the Greeks as Amitrochates, and only advocated for piety ("Dharma") in his Major Pillar Edicts and Major Rock Edicts, without ever mentioning Buddhism, the Buddha, or the Samgha (the single notable exception is the 7th Edict of the Major Pillar Edicts which does mention the Samgha, but is a considered a later fake by Beckwith). Also, the geographical spread of his inscription shows that Piyadasi ruled a vast Empire, contiguous with the Seleucid Empire in the West. On the contrary, for Beckwith, Ashoka was a later king of the 1st–2nd century CE, whose name only appears explicitly in the Minor Rock Edicts and allusively in the Minor Pillar Edicts, and who does mention the Buddha and the Samgha, explicitly promoting Buddhism. The name "Priyadarsi" does occur in two of the minor edicts (Gujarra and Bairat), but Beckwith again considers them as later fabrications. The minor inscriptions cover a very different and much smaller geographical area, clustering in Central India. According to Beckwith, the inscriptions of this later Ashoka were typical of the later forms of "normative Buddhism", which are well attested from inscriptions and Gandhari manuscripts dated to the turn of the millennium, and around the time of the Kushan Empire. The quality of the inscriptions of this Ashoka is significantly lower than the quality of the inscriptions of the earlier Piyadasi. Names and titles The name "A-shoka" literally means "without sorrow". According to an Ashokavadana legend, his mother gave him this name because his birth removed her sorrows. The name Priyadasi is associated with Ashoka in the 3rd–4th century CE Dipavamsa. The term literally means "he who regards amiably", or "of gracious mien" (Sanskrit: Priya-darshi). It may have been a regnal name adopted by Ashoka. A version of this name is used for Ashoka in Greek-language inscriptions: βασιλεὺς Πιοδασσης ("Basileus Piodassēs"). Ashoka's inscriptions mention his title Devanampiya (Sanskrit: Devanampriya, "Beloved of the Gods"). The identification of Devanampiya and Ashoka as the same person is established by the Maski and Gujarra inscriptions, which use both these terms for the king. The title was adopted by other kings, including the contemporary king Devanampiya Tissa of Anuradhapura and Ashoka's descendant Dasharatha Maurya. Date The exact date of Ashoka's birth is not certain, as the extant contemporary Indian texts did not record such details. It is known that he lived in the 3rd century BCE, as his inscriptions mention several contemporary rulers whose dates are known with more certainty, such as Antiochus II Theos, Ptolemy II Philadelphus, Antigonus II Gonatas, Magas of Cyrene, and Alexander (of Epirus or Corinth). Thus, Ashoka must have been born sometime in the late 4th century BCE or early 3rd century BCE (), Ancestry Ashoka's own inscriptions are fairly detailed but make no mention of his ancestors. Other sources, such as the Puranas and the Mahavamsa state that his father was the Mauryan emperor Bindusara, and his grandfather was Chandragupta – the founder of the Empire. The Ashokavadana also names his father as Bindusara, but traces his ancestry to Buddha's contemporary king Bimbisara, through Ajatashatru, Udayin, Munda, Kakavarnin, Sahalin, Tulakuchi, Mahamandala, Prasenajit, and Nanda. The 16th century Tibetan monk Taranatha, whose account is a distorted version of the earlier traditions, describes Ashoka as the illegitimate son of king Nemita of Champarana from the daughter of a merchant. Ashokavadana states that Ashoka's mother was the daughter of a Brahmin from Champa, and was prophesied to marry a king. Accordingly, her father took her to Pataliputra, where she was inducted into Bindusara's harem, and ultimately, became his chief queen. The Ashokavadana does not mention her by name, although other legends provide different names for her. For example, the Asokavadanamala calls her Subhadrangi. The Vamsatthapakasini or Mahavamsa-tika, a commentary on Mahavamsa, calls her "Dharma" ("Dhamma" in Pali), and states that she belonged to the Moriya Kshatriya clan. A Divyavadana legend calls her Janapada-kalyani; according to scholar Ananda W. P. Guruge, this is not a name, but an epithet. According to the 2nd-century historian Appian, Chandragupta entered into a marital alliance with the Greek ruler Seleucus I Nicator, which has led to speculation that either Chandragupta or his son Bindusara married a Greek princess. However, there is no evidence that Ashoka's mother or grandmother was Greek, and most historians have dismissed the idea. As a prince Ashoka's own inscriptions do not describe his early life, and much of the information on this topic comes from apocryphal legends written hundreds of years after him. While these legends include obviously fictitious details such as narratives of Ashoka's past lives, they have some plausible historical information about Ashoka's period. According to the Ashokavadana, Bindusara disliked Ashoka because of his rough skin. One day, Bindusara asked the ascetic Pingala-vatsajiva to determine which of his sons was worthy of being his successor. He asked all the princes to assemble at the Garden of the Golden Pavilion on the ascetic's advice. Ashoka was reluctant to go because his father disliked him, but his mother convinced him to do so. When minister Radhagupta saw Ashoka leaving the capital for the Garden, he offered to provide the prince with a royal elephant for the travel. At the Garden, Pingala-vatsajiva examined the princes and realised that Ashoka would be the next king. To avoid annoying Bindusara, the ascetic refused to name the successor. Instead, he said that one who had the best mount, seat, drink, vessel and food would be the next king; each time, Ashoka declared that he met the criterion. Later, he told Ashoka's mother that her son would be the next king, and on her advice, left the kingdom to avoid Bindusara's wrath. While legends suggest that Bindusara disliked Ashoka's ugly appearance, they also state that Bindusara gave him important responsibilities, such as suppressing a revolt in Takshashila (according to north Indian tradition) and governing Ujjain (according to Sri Lankan tradition). This suggests that Bindusara was impressed by the other qualities of the prince. Another possibility is that he sent Ashoka to distant regions to keep him away from the imperial capital. Rebellion at Taxila According to the Ashokavadana, Bindusara dispatched prince Ashoka to suppress a rebellion in the city of Takshashila (present-day Bhir Mound in Pakistan). This episode is not mentioned in the Sri Lankan tradition, which instead states that Bindusara sent Ashoka to govern Ujjain. Two other Buddhist texts – Ashoka-sutra and Kunala-sutra – state that Bindusara appointed Ashoka as a viceroy in Gandhara (where Takshashila was located), not Ujjain. The Ashokavadana states that Bindusara provided Ashoka with a fourfold-army (comprising cavalry, elephants, chariots and infantry) but refused to provide any weapons for this army. Ashoka declared that weapons would appear before him if he was worthy of being a king, and then, the deities emerged from the earth and provided weapons to the army. When Ashoka reached Takshashila, the citizens welcomed him and told him that their rebellion was only against the evil ministers, not the king. Sometime later, Ashoka was similarly welcomed in the Khasa territory and the gods declared that he would go on to conquer the whole earth. Takshashila was a prosperous and geopolitically influential city, and historical evidence proves that by Ashoka's time, it was well-connected to the Mauryan capital Pataliputra by the Uttarapatha trade route. However, no extant contemporary source mentions the Takshashila rebellion, and none of Ashoka's records states that he ever visited the city. That said, the historicity of the legend about Ashoka's involvement in the Takshashila rebellion may be corroborated by an Aramaic-language inscription discovered at Sirkap near Taxila. The inscription includes a name that begins with the letters "prydr", and most scholars restore it as "Priyadarshi", which was the title of Ashoka. Another evidence of Ashoka's connection to the city may be the name of the Dharmarajika Stupa near Taxila; the name suggests that it was built by Ashoka ("Dharma-raja"). The story about the deities miraculously bringing weapons to Ashoka may be the text's way of deifying Ashoka; or indicating that Bindusara – who disliked Ashoka – wanted him to fail in Takshashila. Governor of Ujjain According to the Mahavamsa, Bindusara appointed Ashoka as the viceroy of present-day Ujjain (Ujjeni), which was an important administrative and commercial centre in the Avanti province of central India. This tradition is corroborated by the Saru Maru inscription discovered in central India; this inscription states that he visited the place as a prince. Ashoka's own rock edict mentions the presence of a prince viceroy at Ujjain during his reign, which further supports the tradition that he himself served as a viceroy at Ujjain. Pataliputra was connected to Ujjain by multiple routes in Ashoka's time, and on the way, Ashoka entourage may have encamped at Rupnath, where his inscription has been found. According to the Sri Lankan tradition, Ashoka visited Vidisha, where he fell in love with a beautiful woman on his way to Ujjain. According to the Dipamvamsa and Mahamvamsa, the woman was Devi – the daughter of a merchant. According to the Mahabodhi-vamsa, she was Vidisha-Mahadevi and belonged to the Shakya clan of Gautama Buddha. The Buddhist chroniclers may have fabricated the Shakya connection to connect Ashoka's family to Buddha. The Buddhist texts allude to her being a Buddhist in her later years but do not describe her conversion to Buddhism. Therefore, it is likely that she was already a Buddhist when she met Ashoka. The Mahavamsa states that Devi gave birth to Ashoka's son Mahinda in Ujjain, and two years later, to a daughter named Sanghamitta. According to the Mahavamsa, Ashoka's son Mahinda was ordained at the age of 20 years, during the sixth year of Ashoka's reign. That means Mahinda must have been 14 years old when Ashoka ascended the throne. Even if Mahinda was born when Ashoka was as young as 20 years old, Ashoka must have ascended the throne at 34 years, which means he must have served as a viceroy for several years. Ascension to the throne Legends suggest that Ashoka was not the crown prince, and his ascension on the throne was disputed. Ashokavadana states that Bindusara's eldest son Susima once slapped a bald minister on his head in jest. The minister worried that after ascending the throne, Susima may jokingly hurt him with a sword. Therefore, he instigated five hundred ministers to support Ashoka's claim to the throne when the time came, noting that Ashoka was predicted to become a chakravartin (universal ruler). Sometime later, Takshashila rebelled again, and Bindusara dispatched Susima to curb the rebellion. Shortly after, Bindusara fell ill and was expected to die soon. Susima was still in Takshashila, having been unsuccessful in suppressing the rebellion. Bindusara recalled him to the capital and asked Ashoka to march to Takshashila. However, the ministers told him that Ashoka was ill and suggested that he temporarily install Ashoka on the throne until Susmia's return from Takshashila. When Bindusara refused to do so, Ashoka declared that if the throne were rightfully his, the gods would crown him as the next king. At that instance, the gods did so, Bindusara died, and Ashoka's authority extended to the entire world, including the Yaksha territory located above the earth and the Naga territory located below the earth. When Susima returned to the capital, Ashoka's newly appointed prime minister Radhagupta tricked him into a pit of charcoal. Susima died a painful death, and his general Bhadrayudha became a Buddhist monk. The Mahavamsa states that when Bindusara fell sick, Ashoka returned to Pataliputra from Ujjain and gained control of the capital. After his father's death, Ashoka had his eldest brother killed and ascended the throne. The text also states that Ashoka killed ninety-nine of his half-brothers, including Sumana. The Dipavamsa states that he killed a hundred of his brothers and was crowned four years later. The Vamsatthapakasini adds that an Ajivika ascetic had predicted this massacre based on the interpretation of a dream of Ashoka's mother. According to these accounts, only Ashoka's uterine brother Tissa was spared. Other sources name the surviving brother Vitashoka, Vigatashoka, Sudatta (So-ta-to in A-yi-uang-chuan), or Sugatra (Siu-ka-tu-lu in Fen-pie-kung-te-hun). The figures such as 99 and 100 are exaggerated and seem to be a way of stating that Ashoka killed several of his brothers. Taranatha states that Ashoka, who was an illegitimate son of his predecessor, killed six legitimate princes to ascend the throne. It is possible that Ashoka was not the rightful heir to the throne and killed a brother (or brothers) to acquire the throne. However, the Buddhist sources have exaggerated the story, which attempts to portray him as evil before his conversion to Buddhism. Ashoka's Rock Edict No. 5 mentions officers whose duties include supervising the welfare of "the families of his brothers, sisters, and other relatives". This suggests that more than one of his brothers survived his ascension. However, some scholars oppose this suggestion, arguing that the inscription talks only about the families of his brothers, not the brothers themselves. Date of ascension According to the Sri Lankan texts Mahavamsa and the Dipavamsa, Ashoka ascended the throne 218 years after the death of Gautama Buddha and ruled for 37 years. The date of the Buddha's death is itself a matter of debate, and the North Indian tradition states that Ashoka ruled a hundred years after the Buddha's death, which has led to further debates about the date. Assuming that the Sri Lankan tradition is correct, and assuming that the Buddha died in 483 BCE – a date proposed by several scholars – Ashoka must have ascended the throne in 265 BCE. The Puranas state that Ashoka's father Bindusara reigned for 25 years, not 28 years as specified in the Sri Lankan tradition. If this is true, Ashoka's ascension can be dated three years earlier, to 268 BCE. Alternatively, if the Sri Lankan tradition is correct, but if we assume that the Buddha died in 486 BCE (a date supported by the Cantonese Dotted Record), Ashoka's ascension can be dated to 268 BCE. The Mahavamsa states that Ashoka consecrated himself as the king four years after becoming a sovereign. This interregnum can be explained assuming that he fought a war of succession with other sons of Bindusara during these four years. The Ashokavadana contains a story about Ashoka's minister Yashas hiding the sun with his hand. Professor P. H. L. Eggermont theorised that this story was a reference to a partial solar eclipse that was seen in northern India on 4 May 249 BCE. According to the Ashokavadana, Ashoka went on a pilgrimage to various Buddhist sites sometime after this eclipse. Ashoka's Rummindei pillar inscription states that he visited Lumbini during his 21st regnal year. Assuming this visit was a part of the pilgrimage described in the text, and assuming that Ashoka visited Lumbini around 1–2 years after the solar eclipse, the ascension date of 268–269 BCE seems more likely. However, this theory is not universally accepted. For example, according to John S. Strong, the event described in the Ashokavadana has nothing to do with chronology, and Eggermont's interpretation grossly ignores the literary and religious context of the legend. Reign before Buddhist influence Both Sri Lankan and North Indian traditions assert that Ashoka was a violent person before Buddhism. Taranatha also states that Ashoka was initially called "Kamashoka" because he spent many years in pleasurable pursuits (kama); he was then called "Chandashoka" ("Ashoka the fierce") because he spent some years performing evil deeds; and finally, he came to be known as Dhammashoka ("Ashoka the righteous") after his conversion to Buddhism. The Ashokavadana also calls him "Chandashoka", and describes several of his cruel acts: The ministers who had helped him ascend the throne started treating him with contempt after his ascension. To test their loyalty, Ashoka gave them the absurd order of cutting down every flower-and fruit-bearing tree. When they failed to carry out this order, Ashoka personally cut off the heads of 500 ministers. One day, during a stroll at a park, Ashoka and his concubines came across a beautiful Ashoka tree. The sight put him in an amorous mood, but the women did not enjoy caressing his rough skin. Sometime later, when Ashoka fell asleep, the resentful women chopped the flowers and the branches of his namesake tree. After Ashoka woke up, he burnt 500 of his concubines to death as punishment. Alarmed by the king's involvement in such massacres, prime minister Radha-Gupta proposed hiring an executioner to carry out future mass killings to leave the king unsullied. Girika, a Magadha village boy who boasted that he could execute the whole of Jambudvipa, was hired for the purpose. He came to be known as Chandagirika ("Girika the fierce"), and on his request, Ashoka built a jail in Pataliputra. Called Ashoka's Hell, the jail looked pleasant from the outside, but inside it, Girika brutally tortured the prisoners. The 5th-century Chinese traveller Faxian states that Ashoka personally visited the underworld to study torture methods there and then invented his methods. The 7th-century traveller Xuanzang claims to have seen a pillar marking the site of Ashoka's "Hell". The Mahavamsa also briefly alludes to Ashoka's cruelty, stating that Ashoka was earlier called Chandashoka because of his evil deeds but came to be called Dharmashoka because of his pious acts after his conversion to Buddhism. However, unlike the north Indian tradition, the Sri Lankan texts do not mention any specific evil deeds performed by Ashoka, except his killing of 99 of his brothers. Such descriptions of Ashoka as an evil person before his conversion to Buddhism appear to be a fabrication of the Buddhist authors, who attempted to present the change that Buddhism brought to him as a miracle. In an attempt to dramatise this change, such legends exaggerate Ashoka's past wickedness and his piousness after the conversion. Kalinga war and conversion to Buddhism Ashoka's inscriptions mention that he conquered the Kalinga region during his 8th regnal year: the destruction caused during the war made him repent violence, and in the subsequent years, he was drawn towards Buddhism. Edict 13 of the Edicts of Ashoka Rock Inscriptions expresses the great remorse the king felt after observing the destruction of Kalinga: On the other hand, the Sri Lankan tradition suggests that Ashoka was already a devoted Buddhist by his 8th regnal year, converted to Buddhism during his 4th regnal year, and constructed 84,000 viharas during his 5th–7th regnal years. The Buddhist legends make no mention of the Kalinga campaign. Based on Sri Lankan tradition, some scholars, such as Eggermont, believe Ashoka converted to Buddhism before the Kalinga war. Critics of this theory argue that if Ashoka were already a Buddhist, he would not have waged the violent Kalinga War. Eggermont explains this anomaly by theorising that Ashoka had his own interpretation of the "Middle Way". Some earlier writers believed that Ashoka dramatically converted to Buddhism after seeing the suffering caused by the war since his Major Rock Edict 13 states that he became closer to the dhamma after the annexation of Kalinga. However, even if Ashoka converted to Buddhism after the war, epigraphic evidence suggests that his conversion was a gradual process rather than a dramatic event. For example, in a Minor Rock Edict issued during his 13th regnal year (five years after the Kalinga campaign), he states that he had been an upasaka (lay Buddhist) for more than two and a half years, but did not make much progress; in the past year, he was drawn closer to the sangha and became a more ardent follower. The Kalinga War According to Ashoka's Major Rock Edict 13, he conquered Kalinga 8 years after ascending to the throne. The edict states that during his conquest of Kalinga, 100,000 men and animals were killed in action; many times that number "perished"; and 150,000 men and animals were carried away from Kalinga as captives. Ashoka states that the repentance of these sufferings caused him to devote himself to the practice and propagation of dharma. He proclaims that he now considered the slaughter, death and deportation caused during the conquest of a country painful and deplorable; and that he considered the suffering caused to the religious people and householders even more deplorable. This edict has been inscribed at several places, including Erragudi, Girnar, Kalsi, Maneshra, Shahbazgarhi and Kandahar. However, it is omitted in Ashoka's inscriptions found in the Kalinga region, where the Rock Edicts 13 and 14 have been replaced by two separate edicts that make no mention of Ashoka's remorse. It is possible that Ashoka did not consider it politically appropriate to make such a confession to the people of Kalinga. Another possibility is the Kalinga war and its consequences, as described in Ashoka's rock edicts, are "more imaginary than real". This description is meant to impress those far removed from the scene, thus unable to verify its accuracy. Ancient sources do not mention any other military activity of Ashoka, although the 16th-century writer Taranatha claims that Ashoka conquered the entire Jambudvipa. First contact with Buddhism Different sources give different accounts of Ashoka's conversion to Buddhism. According to Sri Lankan tradition, Ashoka's father, Bindusara, was a devotee of Brahmanism, and his mother Dharma was a devotee of Ajivikas. The Samantapasadika states that Ashoka followed non-Buddhist sects during the first three years of his reign. The Sri Lankan texts add that Ashoka was not happy with the behaviour of the Brahmins who received his alms daily. His courtiers produced some Ajivika and Nigantha teachers before him, but these also failed to impress him. The Dipavamsa states that Ashoka invited several non-Buddhist religious leaders to his palace and bestowed great gifts upon them in the hope that they would answer a question posed by the king. The text does not state what the question was but mentions that none of the invitees were able to answer it. One day, Ashoka saw a young Buddhist monk called Nigrodha (or Nyagrodha), who was looking for alms on a road in Pataliputra. He was the king's nephew, although the king was not aware of this: he was a posthumous son of Ashoka's eldest brother Sumana, whom Ashoka had killed during the conflict for the throne. Ashoka was impressed by Nigrodha's tranquil and fearless appearance, and asked him to teach him his faith. In response, Nigrodha offered him a sermon on appamada (earnestness). Impressed by the sermon, Ashoka offered Nigrodha 400,000 silver coins and 8 daily portions of rice. The king became a Buddhist upasaka, and started visiting the Kukkutarama shrine at Pataliputra. At the temple, he met the Buddhist monk Moggaliputta Tissa, and became more devoted to the Buddhist faith. The veracity of this story is not certain. This legend about Ashoka's search for a worthy teacher may be aimed at explaining why Ashoka did not adopt Jainism, another major contemporary faith that advocates non-violence and compassion. The legend suggests that Ashoka was not attracted to Buddhism because he was looking for such a faith, rather, for a competent spiritual teacher. The Sri Lankan tradition adds that during his sixth regnal year, Ashoka's son Mahinda became a Buddhist monk, and his daughter became a Buddhist nun. A story in Divyavadana attributes Ashoka's conversion to the Buddhist monk Samudra, who was an ex-merchant from Shravasti. According to this account, Samudra was imprisoned in Ashoka's "Hell", but saved himself using his miraculous powers. When Ashoka heard about this, he visited the monk, and was further impressed by a series of miracles performed by the monk. He then became a Buddhist. A story in the Ashokavadana states that Samudra was a merchant's son, and was a 12-year-old boy when he met Ashoka; this account seems to be influenced by the Nigrodha story. The A-yu-wang-chuan states that a 7-year-old Buddhist converted Ashoka. Another story claims that the young boy ate 500 Brahmanas who were harassing Ashoka for being interested in Buddhism; these Brahmanas later miraculously turned into Buddhist bhikkus at the Kukkutarama monastery, which Ashoka visited. Several Buddhist establishments existed in various parts of India by the time of Ashoka's ascension. It is not clear which branch of the Buddhist sangha influenced him, but the one at his capital Pataliputra is a good candidate. Another good candidate is the one at Mahabodhi: the Major Rock Edict 8 records his visit to the Bodhi Tree – the place of Buddha's enlightenment at Mahabodhi – after his tenth regnal year, and the minor rock edict issued during his 13th regnal year suggests that he had become a Buddhist around the same time. Reign after Buddhist influence Construction of Stupas and Temples Both Mahavamsa and Ashokavadana state that Ashoka constructed 84,000 stupas or viharas. According to the Mahavamsa, this activity took place during his fifth–seventh regnal years. The Ashokavadana states that Ashoka collected seven out of the eight relics of Gautama Buddha, and had their portions kept in 84,000 boxes made of gold, silver, cat's eye, and crystal. He ordered the construction of 84,000 stupas throughout the earth, in towns that had a population of 100,000 or more. He told Elder Yashas, a monk at the Kukkutarama monastery, that he wanted these stupas to be completed on the same day. Yashas stated that he would signal the completion time by eclipsing the sun with his hand. When he did so, the 84,000 stupas were completed at once. The Mahavamsa states that Ashoka ordered construction of 84,000 viharas (monasteries) rather than the stupas to house the relics. Like Ashokavadana, the Mahavamsa describes Ashoka's collection of the relics, but does not mention this episode in the context of the construction activities. It states that Ashoka decided to construct the 84,000 viharas when Moggaliputta Tissa told him that there were 84,000 sections of the Buddha's Dhamma. Ashoka himself began the construction of the Ashokarama vihara, and ordered subordinate kings to build the other viharas. Ashokarama was completed by the miraculous power of Thera Indagutta, and the news about the completion of the 84,000 viharas arrived from various cities on the same day. The construction of following stupas and viharas is credited to Ashoka: Sanchi, Madhya Pradesh, India Dhamek Stupa, Sarnath, Uttar Pradesh, India Mahabodhi Temple, Bihar, India Barabar Caves, Bihar, India Nalanda Mahavihara (some portions like Sariputta Stupa), Bihar, India Taxila University (some portions like Dharmarajika Stupa and Kunala Stupa), Taxila, Pakistan Bhir Mound (reconstructed), Taxila, Pakistan Bharhut stupa, Madhya Pradesh, India Deorkothar Stupa, Madhya Pradesh, India Butkara Stupa, Swat, Pakistan Sannati Stupa, Karnataka, India Mir Rukun Stupa, Nawabshah, Pakistan Propagation of Dhamma Ashoka's rock edicts suggest that during his eighth–ninth regnal years, he made a pilgrimage to the Bodhi Tree, started propagating dhamma, and performed social welfare activities. The welfare activities included establishment of medical treatment facilities for humans and animals; plantation of medicinal herbs; and digging of wells and plantation of trees along the roads. These activities were conducted in the neighbouring kingdoms, including those of the Cholas, the Pandyas, the Satiyaputras, Tamraparni, the Greek kingdom of Antiyoka. The edicts also state that during his tenth–eleventh regnal years, Ashoka became closer to the Buddhist sangha, and went on a tour of the empire that lasted for at least 256 days. By his 12th regnal year, Ashoka had started inscribing edicts to propagate dhamma, having ordered his officers (rajjukas and pradesikas) to tour their jurisdictions every five years for inspection and for preaching dhamma. By the next year, he had set up the post of the dharma-mahamatra. During his 14th regnal year, he commissioned the enlargement of the stupa of Buddha Kanakamuni. Third Buddhist Council The Sri Lankan tradition presents a greater role for Ashoka in the Buddhist community. In this tradition, Ashoka starts feeding monks on a large scale. His lavish patronage to the state patronage leads to many fake monks joining the sangha. The true Buddhist monks refuse to co-operate with these fake monks, and therefore, no uposatha ceremony is held for seven years. The king attempts to eradicate the fake monks, but during this attempt, an over-zealous minister ends up killing some real monks. The king then invites the elder monk Moggaliputta-Tissa, to help him expel non-Buddhists from the monastery founded by him at Pataliputra. 60,000 monks (bhikkhus) convicted of being heretical are de-frocked in the ensuing process. The uposatha ceremony is then held, and Tissa subsequently organises the Third Buddhist council, during the 17th regnal year of Ashoka. Tissa compiles Kathavatthu, a text that reaffirms Theravadin orthodoxy on several points. The North Indian tradition makes no mention of these events, which has led to doubts about the historicity of the Third Buddhist council. Richard Gombrich argues that the non-corroboration of this story by inscriptional evidence cannot be used to dismiss it as completely unhistorical, as several of Ashoka's inscriptions may have been lost. Gombrich also argues that Asohka's inscriptions prove that he was interested in maintaining the "unanimity and purity" of the Sangha. For example, in his Minor Rock Edict 3, Ashoka recommends the members of the Sangha to study certain texts (most of which remain unidentified). Similarly, in an inscription found at Sanchi, Sarnath, and Kosam, Ashoka mandates that the dissident members of the sangha should be expelled, and expresses his desire to the Sangha remain united and flourish. The 8th century Buddhist pilgrim Yijing records another story about Ashoka's involvement in the Buddhist sangha. According to this story, the earlier king Bimbisara, who was a contemporary of the Gautama Buddha, once saw 18 fragments of a cloth and a stick in a dream. The Buddha interpreted the dream to mean that his philosophy would be divided into 18 schools after his death, and predicted that a king called Ashoka would unite these schools over a hundred years later. Buddhist missions In the Sri Lankan tradition, Moggaliputta-Tissa – who is patronised by Ashoka – sends out nine Buddhist missions to spread Buddhism in the "border areas" in . This tradition does not credit Ashoka directly with sending these missions. Each mission comprises five monks, and is headed by an elder. To Sri Lanka, he sent his own son Mahinda, accompanied by four other Theras – Itthiya, Uttiya, Sambala and Bhaddasala. Next, with Moggaliputta-Tissa's help, Ashoka sent Buddhist missionaries to distant regions such as Kashmir, Gandhara, Himalayas, the land of the Yonas (Greeks), Maharashtra, Suvannabhumi, and Sri Lanka. The Sri Lankan tradition dates these missions to Ashoka's 18th regnal year, naming the following missionaries: Mahinda to Sri Lanka Majjhantika to Kashmir and Gandhara Mahadeva to Mahisa-mandala (possibly modern Mysore region) Rakkhita to Vanavasa Dhammarakkhita the Greek to Aparantaka (western India) Maha-dhamma-rakkhita to Maharashtra Maharakkhita to the Greek country Majjhima to the Himalayas Soṇa and Uttara to Suvaṇṇabhūmi (possibly Lower Burma and Thailand) The tradition adds that during his 19th regnal year, Ashoka's daughter Sanghamitta went to Sri Lanka to establish an order of nuns, taking a sapling of the sacred Bodhi Tree with her. The North Indian tradition makes no mention of these events. Ashoka's own inscriptions also appear to omit any mention of these events, recording only one of his activities during this period: in his 19th regnal year, he donated the Khalatika Cave to ascetics to provide them a shelter during the rainy season. Ashoka's Pillar Edicts suggest that during the next year, he made pilgrimage to Lumbini – the place of Buddha's birth, and to the stupa of the Buddha Kanakamuni. The Rock Edict XIII states that Ashoka's won a "dhamma victory" by sending messengers to five kings and several other kingdoms. Whether these missions correspond to the Buddhist missions recorded in the Buddhist chronicles is debated. Indologist Etienne Lamotte argues that the "dhamma" missionaries mentioned in Ashoka's inscriptions were probably not Buddhist monks, as this "dhamma" was not same as "Buddhism". Moreover, the lists of destinations of the missions and the dates of the missions mentioned in the inscriptions do not tally the ones mentioned in the Buddhist legends. Other scholars, such as Erich Frauwallner and Richard Gombrich, believe that the missions mentioned in the Sri Lankan tradition are historical. According to these scholars, a part of this story is corroborated by archaeological evidence: the Vinaya Nidana mentions names of five monks, who are said to have gone to the Himalayan region; three of these names have been found inscribed on relic caskets found at Bhilsa (near Vidisha). These caskets have been dated to the early 2nd century BCE, and the inscription states that the monks are of the Himalayan school. The missions may have set out from Vidisha in central India, as the caskets were discovered there, and as Mahinda is said to have stayed there for a month before setting out for Sri Lanka. According to Gombrich, the mission may have included representatives of other religions, and thus, Lamotte's objection about "dhamma" is not valid. The Buddhist chroniclers may have decided not to mention these non-Buddhists, so as not to sideline Buddhism. Frauwallner and Gombrich also believe that Ashoka was directly responsible for the missions, since only a resourceful ruler could have sponsored such activities. The Sri Lankan chronicles, which belong to the Theravada school, exaggerate the role of the Theravadin monk Moggaliputta-Tissa in order to glorify their sect. Some historians argue that Buddhism became a major religion because of Ashoka's royal patronage. However, epigraphic evidence suggests that the spread of Buddhism in north-western India and Deccan region was less because of Ashoka's missions, and more because of merchants, traders, landowners and the artisan guilds who supported Buddhist establishments. Violence after conversion According to the Ashokavadana, Ashoka resorted to violence even after converting to Buddhism. For example: He slowly tortured Chandagirika to death in the "hell" prison. He ordered a massacre of 18,000 heretics for a misdeed of one. He launched a pogrom against the Jains, announcing a bounty on the head of any heretic; this resulted in the beheading of his own brother – Vitashoka. According to the Ashokavadana, a non-Buddhist in Pundravardhana drew a picture showing the Buddha bowing at the feet of the Nirgrantha leader Jnatiputra. The term nirgrantha ("free from bonds") was originally used for a pre-Jaina ascetic order, but later came to be used for Jaina monks. "Jnatiputra" is identified with Mahavira, 24th Tirthankara of Jainism. The legend states that on complaint from a Buddhist devotee, Ashoka issued an order to arrest the non-Buddhist artist, and subsequently, another order to kill all the Ajivikas in Pundravardhana. Around 18,000 followers of the Ajivika sect were executed as a result of this order. Sometime later, another Nirgrantha follower in Pataliputra drew a similar picture. Ashoka burnt him and his entire family alive in their house. He also announced an award of one dinara (gold coin) to anyone who brought him the head of a Nirgrantha heretic. According to Ashokavadana, as a result of this order, his own brother was mistaken for a heretic and killed by a cowherd. Ashoka realised his mistake, and withdrew the order. For several reasons, scholars say, these stories of persecutions of rival sects by Ashoka appear to be clear fabrications arising out of sectarian propaganda. Family Queens Various sources mention five consorts of Ashoka: Devi (or Vedisa-Mahadevi-Shakyakumari), Karuvaki, Asandhimitra (Pali: Asandhimitta), Padmavati, and Tishyarakshita (Pali: Tissarakkha). Karuvaki is the only queen of Ashoka known from his own inscriptions: she is mentioned in an edict inscribed on a pillar at Allahabad. The inscription names her as the mother of prince Tivara, and orders the royal officers (mahamattas) to record her religious and charitable donations. According to one theory, Tishyarakshita was the regnal name of Kaurvaki. According to the Mahavamsa, Ashoka's chief queen was Asandhimitta, who died four years before him. It states that she was born as Ashoka's queen because in a previous life, she directed a pratyekabuddha to a honey merchant (who was later reborn as Ashoka). Some later texts also state that she additionally gave the pratyekabuddha a piece of cloth made by her. These texts include the Dasavatthuppakarana, the so-called Cambodian or Extended Mahavamsa (possibly from 9th–10th centuries), and the Trai Bhumi Katha (15th century). These texts narrate another story: one day, Ashoka mocked Asandhamitta was enjoying a tasty piece of sugarcane without having earned it through her karma. Asandhamitta replied that all her enjoyments resulted from merit resulting from her own karma. Ashoka then challenged her to prove this by procuring 60,000 robes as an offering for monks. At night, the guardian gods informed her about her past gift to the pratyekabuddha, and next day, she was able to miraculously procure the 60,000 robes. An impressed Ashoka makes her his favourite queen, and even offers to make her a sovereign ruler. Asandhamitta refuses the offer, but still invokes the jealousy of Ashoka's 16,000 other women. Ashoka proves her superiority by having 16,000 identical cakes baked with his royal seal hidden in only one of them. Each wife is asked to choose a cake, and only Asandhamitta gets the one with the royal seal. The Trai Bhumi Katha claims that it was Asandhamitta who encouraged her husband to become a Buddhist, and to construct 84,000 stupas and 84,000 viharas. According to Mahavamsa, after Asandhamitta's death, Tissarakkha became the chief queen. The Ashokavadana does not mention Asandhamitta at all, but does mention Tissarakkha as Tishyarakshita. The Divyavadana mentions another queen called Padmavati, who was the mother of the crown-prince Kunala. As mentioned above, according to the Sri Lankan tradition, Ashoka fell in love with Devi (or Vidisha-Mahadevi), as a prince in central India. After Ashoka's ascension to the throne, Devi chose to remain at Vidisha than move to the royal capital Pataliputra. According to the Mahavmsa, Ashoka's chief queen was Asandhamitta, not Devi: the text does not talk of any connection between the two women, so it is unlikely that Asandhamitta was another name for Devi. The Sri Lankan tradition uses the word samvasa to describe the relationship between Ashoka and Devi, which modern scholars variously interpret as sexual relations outside marriage, or co-habitation as a married couple. Those who argue that Ashoka did not marry Devi argue that their theory is corroborated by the fact that Devi did not become Ashoka's chief queen in Pataliputra after his ascension. The Dipavamsa refers to two children of Ashoka and Devi – Mahinda and Sanghamitta. Sons Tivara, the son of Ashoka and Karuvaki, is the only of Ashoka's sons to be mentioned by name in the inscriptions. According to North Indian tradition, Ashoka had a son named Kunala. Kunala had a son named Samprati. The Sri Lankan tradition mentions a son called Mahinda, who was sent to Sri Lanka as a Buddhist missionary; this son is not mentioned at all in the North Indian tradition. The Chinese pilgrim Xuanzang states that Mahinda was Ashoka's younger brother (Vitashoka or Vigatashoka) rather than his illgetimate son. The Divyavadana mentions the crown-prince Kunala alias Dharmavivardhana, who was a son of queen Padmavati. According to Faxian, Dharmavivardhana was appointed as the governor of Gandhara. The Rajatarangini mentions Jalauka as a son of Ashoka. Daughters According to Sri Lankan tradition, Ashoka had a daughter named Sanghamitta, who became a Buddhist nun. A section of historians, such as Romila Thapar, doubt the historicity of Sanghamitta, based on the following points: The name "Sanghamitta", which literally means the friend of the Buddhist Order (sangha), is unusual, and the story of her going to Ceylon so that the Ceylonese queen could be ordained appears to be an exaggeration. The Mahavamsa states that she married Ashoka's nephew Agnibrahma, and the couple had a son named Sumana. The contemporary laws regarding exogamy would have forbidden such a marriage between first cousins. According to the Mahavamsa, she was 18 years old when she was ordained as a nun. The narrative suggests that she was married two years earlier, and that her husband as well as her child were ordained. It is unlikely that she would have been allowed to become a nun with such a young child. Another source mentions that Ashoka had a daughter named Charumati, who married a kshatriya named Devapala. Brothers According to the Ashokavadana, Ashoka had an elder half-brother named Susima. According to Sri Lankan tradition, this brother was Tissa, who initially lived a luxurious life, without worrying about the world. To teach him a lesson, Ashoka put him on the throne for a few days, then accused him of being an usurper, and sentenced him to die after seven days. During these seven days, Tissa realised that the Buddhist monks gave up pleasure because they were aware of the eventual death. He then left the palace, and became an arhat. The Theragatha commentary calls this brother Vitashoka. According to this legend, one day, Vitashoka saw a grey hair on his head, and realised that he had become old. He then retired to a monastery, and became an arhat. Faxian calls the younger brother Mahendra, and states that Ashoka shamed him for his immoral behaviour. The brother than retired to a dark cave, where he meditated, and became an arhat. Ashoka invited him to return to the family, but he preferred to live alone on a hill. So, Ashoka had a hill built for him within Pataliputra. The Ashoka-vadana states that Ashoka's brother was mistaken for a Nirgrantha, and killed during a massacre of the Nirgranthas ordered by Ashoka. Imperial extent The extent of the territory controlled by Ashoka's predecessors is not certain, but it is possible that the empire of his grandfather Chandragupta extended across northern India from the western coast (Arabian Sea) to the eastern coast (Bay of Bengal), covering nearly two-thirds of the Indian subcontinent. Bindusara and Ashoka seem to have extended the empire southwards. The distribution of Ashoka's inscriptions suggests that his empire included almost the entire Indian subcontinent, except its southernmost parts. The Rock Edicts 2 and 13 suggest that these southernmost parts were controlled by the Cholas, the Pandyas, the Keralaputras, and the Satiyaputras. In the north-west, Ashoka's kingdom extended up to Kandahar, to the east of the Seleucid Empire ruled by Antiochus II. The capital of Ashoka's empire was Pataliputra in the Magadha region. Religion and philosophy Relationship with Buddhism The Buddhist legends state that Ashoka converted to Buddhism, although this has been debated by a section of scholars. The Minor Rock Edict 1 leaves no doubt that Ashoka was a follower of Buddhism. In this edict, he calls himself an upasaka (a lay follower of Buddhism) and a sakya (i.e. Buddhist, after Gautama Buddha's title Shakya-Muni). This and several other edicts are evidence of his Buddhist affiliation: In his Minor Rock Edict 1, Ashoka adds that he did not make much progress for a year after becoming an upasaka, but then, he "went to" the Sangha, and made more progress. It is not certain what "going to" the Sangha means – the Buddhist tradition that he lived with monks may be an exaggeration, but it clearly means that Ashoka was drawn closer to Buddhism. In his Minor Rock Edict 3, he calls himself an upasaka, and records his faith in the Buddha and the Sangha. In the Major Rock Edict 8, he records his visit to Sambodhi (the sacred Bodhi Tree at Bodh Gaya), ten years after his coronation. In the Lumbini (Rumminidei) inscription, he records his visit to the Buddha's birthplace, and declares his reverence for the Buddha and the sangha. In the Nigalisagar inscription, he records his doubling in size of a stupa dedicated to a former Buddha, and his visit to the site for worship. Some of his inscriptions reflect his interest in maintaining the Buddhist sangha (see #Purification of sangha below). The Saru Maru inscription states that Ashoka dispatched the message while travelling to Upunita-vihara in Manema-desha. Although the identity of the destination is not certain, it was obviously a Buddhist monastery (vihara). Other religions A legend in the Buddhist text Vamsatthapakasini states that an Ajivika ascetic invited to interpret a dream of Ashoka's mother had predicted that he would patronise Buddhism and destroy 96 heretical sects. However, such assertions are directly contradicted by Ashoka's own inscriptions. Ashoka's edicts, such as the Rock Edicts 6, 7, and 12, emphasise tolerance of all sects. Similarly, in his Rock Edict 12, Ashoka honours people of all faiths. In his inscriptions, Ashoka dedicates caves to non-Buddhist ascetics, and repeatedly states that both Brahmins and shramanas deserved respect. He also tells people "not to denigrate other sects, but to inform themselves about them". In fact, there is no evidence that Buddhism was a state religion under Ashoka. None of Ashoka's extant edicts record his direct donations to the Buddhists. One inscription records donations by his queen Karuvaki, while the emperor is known to have donated the Barabar Caves to the Ajivikas. There are some indirect references to his donations to Buddhists. For example, the Nigalisagar Pillar inscription records his enlargement of the Konakamana stupa. Similarly, the Lumbini (Rumminidei) inscription states that he exempted the village of Buddha's birth from the land tax, and reduced the revenue tax to one-eighth. Ashoka appointed the dhamma-mahamatta officers, whose duties included the welfare of various religious sects, including the Buddhist sangha, Brahmins, Ajivikas, and Nirgranthas. The Rock Edicts 8 and 12, and the Pillar Edict 7, mandate donations to all religious sects. Ashoka's Minor Rock Edict 1 contains the phrase "amissā devā". According to one interpretation, the term "amissā" derives from the word "amṛṣa" ("false"), and thus, the phrase is a reference to Ashoka's belief in "true" and "false" gods. However, it is more likely that the term derives from the word "amiśra" ("not mingled"), and the phrase refers to celestial beings who did not mingle with humans. The inscription claims that the righteousness generated by adoption of dhamma by the humans attracted even the celestial gods who did not mingle with humans. Dharma Ashoka's various inscriptions suggest that he devoted himself to the propagation of "Dharma" (Pali: Dhamma), a term that refers to the teachings of Gautama Buddha in the Buddhist circles. However, Ashoka's own inscriptions do not mention Buddhist doctrines such as the Four Noble Truths or Nirvana. The word "Dharma" has various connotations in the Indian religions, and can be generally translated as "law, duty, or righteousness". In the Kandahar inscriptions of Ashoka, the word "Dharma" has been translated as eusebeia (Greek) and qsyt (Aramaic), which further suggests that his "Dharma" meant something more generic than Buddhism. The inscriptions suggest that for Ashoka, Dharma meant "a moral polity of active social concern, religious tolerance, ecological awareness, the observance of common ethical precepts, and the renunciation of war." For example: Abolition of the death penalty (Pillar Edict IV) Plantation of banyan trees and mango groves, and construction of resthouses and wells, every along the roads. (Pillar Edict 7). Restriction on killing of animals in the royal kitchen (Rock Edict 1); the number of animals killed was limited to two peacocks and a deer daily, and in future, even these animals were not to be killed. Provision of medical facilities for humans and animals (Rock Edict 2). Encouragement of obedience to parents, "generosity toward priests and ascetics, and frugality in spending" (Rock Edict 3). He "commissions officers to work for the welfare and happiness of the poor and aged" (Rock Edict 5) Promotion of "the welfare of all beings so as to pay off his debt to living creatures and to work for their happiness in this world and the next." (Rock Edict 6) Modern scholars have variously understood this dhamma as a Buddhist lay ethic, a set of politico-moral ideas, a "sort of universal religion", or as an Ashokan innovation. On the other hand, it has also been interpreted as an essentially political ideology that sought to knit together a vast and diverse empire. Ashoka instituted a new category of officers called the dhamma-mahamattas, who were tasked with the welfare of the aged, the infirm, the women and children, and various religious sects. They were also sent on diplomatic missions to the Hellenistic kingdoms of west Asia, in order to propagate the dhamma. Historically, the image of Ashoka in the global Buddhist circles was based on legends (such as those mentioned in the Ashokavadana) rather than his rock edicts. This was because the Brahmi script in which these edicts were written was forgotten soon and remained undeciphered until its study by James Prinsep in the 19th century. The writings of the Chinese Buddhist pilgrims such as Faxian and Xuanzang suggest that Ashoka's inscriptions mark the important sites associated with Gautama Buddha. These writers attribute Buddhism-related content to Ashoka's edicts, but this content does not match with the actual text of the inscriptions as determined by modern scholars after the decipherment of the Brahmi script. It is likely that the script was forgotten by the time of Faxian, who probably relied on local guides; these guides may have made up some Buddhism-related interpretations to gratify him, or may have themselves relied on faulty translations based on oral traditions. Xuanzang may have encountered a similar situation, or may have taken the supposed content of the inscriptions from Faxian's writings. This theory is corroborated by the fact that some Brahmin scholars are known to have similarly come up with a fanciful interpretation of Ashoka pillar inscriptions, when requested to decipher them by the 14th century Muslim king Firuz Shah Tughlaq. According to Shams-i Siraj's Tarikh-i Firoz Shahi, after the king had these pillar transported from Topra and Mirat to Delhi as war trophies, these Brahmins told him that the inscriptions prophesied that nobody would be able to remove the pillars except a king named Firuz. Moreover, by this time, there were local traditions that attributed the erection of these pillars to the legendary hero Bhima. According to scholars such as Richard Gombrich, Ashoka's dharma shows Buddhist influence. For example, the Kalinga Separate Edict I seems to be inspired by Buddha's Advice to Sigala and his other sermons. Animal welfare Ashoka's rock edicts declare that injuring living things is not good, and no animal should be slaughtered for sacrifice. However, he did not prohibit common cattle slaughter or beef eating. He imposed a ban on killing of "all four-footed creatures that are neither useful nor edible", and of specific animal species including several birds, certain types of fish and bulls among others. He also banned killing of female goats, sheep and pigs that were nursing their young; as well as their young up to the age of six months. He also banned killing of all fish and castration of animals during certain periods such as Chaturmasa and Uposatha. Ashoka also abolished the royal hunting of animals and restricted the slaying of animals for food in the royal residence. Because he banned hunting, created many veterinary clinics and eliminated meat eating on many holidays, the Mauryan Empire under Ashoka has been described as "one of the very few instances in world history of a government treating its animals as citizens who are as deserving of its protection as the human residents". Foreign relations It is well known that Ashoka sent dütas or emissaries to convey messages or letters, written or oral (rather both), to various people. The VIth Rock Edict about "oral orders" reveals this. It was later confirmed that it was not unusual to add oral messages to written ones, and the content of Ashoka's messages can be inferred likewise from the XIIIth Rock Edict: They were meant to spread his dhammavijaya, which he considered the highest victory and which he wished to propagate everywhere (including far beyond India). There is obvious and undeniable trace of cultural contact through the adoption of the Kharosthi script, and the idea of installing inscriptions might have travelled with this script, as Achaemenid influence is seen in some of the formulations used by Ashoka in his inscriptions. This indicates to us that Ashoka was indeed in contact with other cultures, and was an active part in mingling and spreading new cultural ideas beyond his own immediate walls. Hellenistic world In his rock edicts, Ashoka states that he had encouraged the transmission of Buddhism to the Hellenistic kingdoms to the west and that the Greeks in his dominion were converts to Buddhism and recipients of his envoys: It is possible, but not certain, that Ashoka received letters from Greek rulers and was acquainted with the Hellenistic royal orders in the same way as he perhaps knew of the inscriptions of the Achaemenid kings, given the presence of ambassadors of Hellenistic kings in India (as well as the dütas sent by Ashoka himself). Dionysius is reported to have been such a Greek ambassador at the court of Ashoka, sent by Ptolemy II Philadelphus, who himself is mentioned in the Edicts of Ashoka as a recipient of the Buddhist proselytism of Ashoka. Some Hellenistic philosophers, such as Hegesias of Cyrene, who probably lived under the rule of King Magas, one of the supposed recipients of Buddhist emissaries from Asoka, are sometimes thought to have been influenced by Buddhist teachings. The Greeks in India even seem to have played an active role in the propagation of Buddhism, as some of the emissaries of Ashoka, such as Dharmaraksita, are described in Pali sources as leading Greek (Yona) Buddhist monks, active in spreading Buddhism (the Mahavamsa, XII). Some Greeks (Yavana) may have played an administrative role in the territories ruled by Ashoka. The Girnar inscription of Rudradaman records that during the rule of Ashoka, a Yavana Governor was in charge in the area of Girnar, Gujarat, mentioning his role in the construction of a water reservoir. It is thought that Ashoka's palace at Patna was modelled after the Achaemenid palace of Persepolis. Legends about past lives Buddhist legends mention stories about Ashoka's past lives. According to a Mahavamsa story, Ashoka, Nigrodha and Devnampiya Tissa were brothers in a previous life. In that life, a pratyekabuddha was looking for honey to cure another, sick pratyekabuddha. A woman directed him to a honey shop owned by the three brothers. Ashoka generously donated honey to the pratyekabuddha, and wished to become the sovereign ruler of Jambudvipa for this act of merit. The woman wished to become his queen, and was reborn as Ashoka's wife Asandhamitta. Later Pali texts credit her with an additional act of merit: she gifted the pratyekabuddha a piece of cloth made by her. These texts include the Dasavatthuppakarana, the so-called Cambodian or Extended Mahavamsa (possibly from 9th–10th centuries), and the Trai Bhumi Katha (15th century). According to an Ashokavadana story, Ashoka was born as Jaya in a prominent family of Rajagriha. When he was a little boy, he gave the Gautama Buddha dirt imagining it to be food. The Buddha approved of the donation, and Jaya declared that he would become a king by this act of merit. The text also state that Jaya's companion Vijaya was reborn as Ashoka's prime-minister Radhagupta. In the later life, the Buddhist monk Upagupta tells Ashoka that his rough skin was caused by the impure gift of dirt in the previous life. Some later texts repeat this story, without mentioning the negative implications of gifting dirt; these texts include Kumaralata's Kalpana-manditika, Aryashura's Jataka-mala, and the Maha-karma-vibhaga. The Chinese writer Pao Ch'eng's Shih chia ju lai ying hua lu asserts that an insignificant act like gifting dirt could not have been meritorious enough to cause Ashoka's future greatness. Instead, the text claims that in another past life, Ashoka commissioned a large number of Buddha statues as a king, and this act of merit caused him to become a great emperor in the next life. The 14th century Pali-language fairy tale Dasavatthuppakarana (possibly from ) combines the stories about the merchant's gift of honey, and the boy's gift of dirt. It narrates a slightly different version of the Mahavamsa story, stating that it took place before the birth of the Gautama Buddha. It then states that the merchant was reborn as the boy who gifted dirt to the Buddha; however, in this case, the Buddha his attendant to Ānanda to create plaster from the dirt, which is used repair cracks in the monastery walls. Last years Tissarakkha as the queen Ashoka's last dated inscription - the Pillar Edict 4 is from his 26th regnal year. The only source of information about Ashoka's later years are the Buddhist legends. The Sri Lankan tradition states that Ashoka's queen Asandhamitta died during his 29th regnal year, and in his 32nd regnal year, his wife Tissarakkha was given the title of queen. Both Mahavamsa and Ashokavadana state that Ashoka extended favours and attention to the Bodhi Tree, and a jealous Tissarakkha mistook "Bodhi" to be a mistress of Ashoka. She then used black magic to make the tree wither. According to the Ashokavadana, she hired a sorceress to do the job, and when Ashoka explained that "Bodhi" was the name of a tree, she had the sorceress heal the tree. According to the Mahavamsa, she completely destroyed the tree, during Ashoka's 34th regnal year. The Ashokavadana states that Tissarakkha (called "Tishyarakshita" here) made sexual advances towards Ashoka's son Kunala, but Kunala rejected her. Subsequently, Ashoka granted Tissarakkha kingship for seven days, and during this period, she tortured and blinded Kunala. Ashoka then threatened to "tear out her eyes, rip open her body with sharp rakes, impale her alive on a spit, cut off her nose with a saw, cut out her tongue with a razor." Kunala regained his eyesight miraculously, and pleaded for mercy for the queen, but Ashoka had her executed anyway. Kshemendra's Avadana-kalpa-lata also narrates this legend, but seeks to improve Ashoka's image by stating that he forgave the queen after Kunala regained his eyesight. Death According to the Sri Lankan tradition, Ashoka died during his 37th regnal year, which suggests that he died around 232 BCE. According to the Ashokavadana, the emperor fell severely ill during his last days. He started using state funds to make donations to the Buddhist sangha, prompting his ministers to deny him access to the state treasury. Ashoka then started donating his personal possessions, but was similarly restricted from doing so. On his deathbed, his only possession was the half of a myrobalan fruit, which he offered to the sangha as his final donation. Such legends encourage generous donations to the sangha and highlight the role of the kingship in supporting the Buddhist faith. Legend states that during his cremation, his body burned for seven days and nights. Legacy In The Outline of History (1920), H. G. Wells wrote, "Amidst the tens of thousands of names of monarchs that crowd the columns of history, their majesties and graciousnesses and serenities and royal highnesses and the like, the name of Ashoka shines, and shines, almost alone, a star." Architecture Besides the various stupas attributed to Ashoka, the pillars erected by him survive at various places in the Indian subcontinent. Ashoka is often credited with the beginning of stone architecture in India, possibly following the introduction of stone-building techniques by the Greeks after Alexander the Great. Before Ashoka's time, buildings were probably built in non-permanent material, such as wood, bamboo or thatch. Ashoka may have rebuilt his palace in Pataliputra by replacing wooden material by stone, and may also have used the help of foreign craftmen. Ashoka also innovated by using the permanent qualities of stone for his written edicts, as well as his pillars with Buddhist symbolism. Symbols Ashokan capitals were highly realistic and used a characteristic polished finish, Mauryan polish, giving a shiny appearance to the stone surface. Lion Capital of Ashoka, the capital of one of the pillars erected by Ashoka features a carving of a spoked wheel, known as the Ashoka Chakra. This wheel represents the wheel of Dhamma set in motion by the Gautama Buddha, and appears on the flag of modern India. This capital also features sculptures of lions, which appear on the seal of India. Inscriptions The edicts of Ashoka are a collection of 33 inscriptions on the Pillars of Ashoka, as well as boulders and cave walls, issued during his reign. These inscriptions are dispersed throughout modern-day Pakistan and India, and represent the first tangible evidence of Buddhism. The edicts describe in detail the first wide expansion of Buddhism through the sponsorship of one of the most powerful kings of Indian history, offering more information about Ashoka's proselytism, moral precepts, religious precepts, and his notions of social and animal welfare. Before Ashoka, the royal communications appear to have been written on perishable materials such as palm leaves, birch barks, cotton cloth, and possibly wooden boards. While Ashoka's administration would have continued to use these materials, Ashoka also had his messages inscribed on rock edicts. Ashoka probably got the idea of putting up these inscriptions from the neighbouring Achaemenid empire. It is likely that Ashoka's messages were also inscribed on more perishable materials, such as wood, and sent to various parts of the empire. None of these records survive now. Scholars are still attempting to analyse both the expressed and implied political ideas of the Edicts (particularly in regard to imperial vision), and make inferences pertaining to how that vision was grappling with problems and political realities of a "virtually subcontinental, and culturally and economically highly variegated, 3rd century BCE Indian empire. Nonetheless, it remains clear that Ashoka's Inscriptions represent the earliest corpus of royal inscriptions in the Indian subcontinent, and therefore prove to be a very important innovation in royal practices." Most of Ashoka's inscriptions are written in a mixture of various Prakrit dialects, in the Brahmi script. Several of Ashoka's inscriptions appear to have been set up near towns, on important routes, and at places of religious significance. Many of the inscriptions have been discovered in hills, rock shelters, and places of local significance. Various theories have been put forward about why Ashoka or his officials chose such places, including that they were centres of megalithic cultures, were regarded as sacred spots in Ashoka's time, or that their physical grandeur may be symbolic of spiritual dominance. Ashoka's inscriptions have not been found at major cities of the Maurya empire, such as Pataliputra, Vidisha, Ujjayini, and Taxila. It is possible that many of these inscriptions are lost; the 7th century Chinese pilgrim Xuanzang refers to some of Ashoka's pillar edicts, which have not been discovered by modern researchers. It appears that Ashoka dispatched every message to his provincial governors, who in turn, relayed it to various officials in their territory. For example, the Minor Rock Edict 1 appears in several versions at multiple places: all the versions state that Ashoka issued the proclamation while on a tour, having spent 256 days on tour. The number 256 indicates that the message was dispatched simultaneously to various places. Three versions of a message, found at edicts in the neighbouring places in Karnataka (Brahmagiri, Siddapura, and Jatinga-Rameshwara), were sent from the southern province's capital Suvarnagiri to various places. All three versions contain the same message, preceded by an initial greeting from the arya-putra (presumably Ashoka's son and the provincial governor) and the mahamatras (officials) in Suvarnagiri. Coinage The caduceus appears as a symbol of the punch-marked coins of the Maurya Empire in India, in the 3rd–2nd century BCE. Numismatic research suggests that this symbol was the symbol of king Ashoka, his personal "Mudra". This symbol was not used on the pre-Mauryan punch-marked coins, but only on coins of the Maurya period, together with the three arched-hill symbol, the "peacock on the hill", the triskelis and the Taxila mark. Modern scholarship Rediscovery Ashoka had almost been forgotten, but in the 19th century James Prinsep contributed in the revelation of historical sources. After deciphering the Brahmi script, Prinsep had originally identified the "Priyadasi" of the inscriptions he found with the King of Ceylon Devanampiya Tissa. However, in 1837, George Turnour discovered an important Sri Lankan manuscript (Dipavamsa, or "Island Chronicle" ) associating Piyadasi with Ashoka: Since then, the association of "Devanampriya Priyadarsin" with Ashoka was confirmed through various inscriptions, and especially confirmed in the Minor Rock Edict inscription discovered in Maski, directly associating Ashoka with his regnal title Devanampriya ("Beloved-of-the-Gods"): Another important historian was British archaeologist John Hubert Marshall, who was director-General of the Archaeological Survey of India. His main interests were Sanchi and Sarnath, in addition to Harappa and Mohenjodaro. Sir Alexander Cunningham, a British archaeologist and army engineer, and often known as the father of the Archaeological Survey of India, unveiled heritage sites like the Bharhut Stupa, Sarnath, Sanchi, and the Mahabodhi Temple. Mortimer Wheeler, a British archaeologist, also exposed Ashokan historical sources, especially the Taxila. Perceptions and historiography The use of Buddhist sources in reconstructing the life of Ashoka has had a strong influence on perceptions of Ashoka, as well as the interpretations of his Edicts. Building on traditional accounts, early scholars regarded Ashoka as a primarily Buddhist monarch who underwent a conversion from the Vedic religion to Buddhism and was actively engaged in sponsoring and supporting the Buddhist monastic institution. Some scholars have tended to question this assessment. Romila Thappar writes about Ashoka that "We need to see him both as a statesman in the context of inheriting and sustaining an empire in a particular historical period, and as a person with a strong commitment to changing society through what might be called the propagation of social ethics." The only source of information not attributable to Buddhist sources are the Ashokan Edicts, and these do not explicitly state that Ashoka was a Buddhist. In his edicts, Ashoka expresses support for all the major religions of his time: Buddhism, Brahmanism, Jainism, and Ajivikaism, and his edicts addressed to the population at large (there are some addressed specifically to Buddhists; this is not the case for the other religions) generally focus on moral themes members of all the religions would accept. For example, Amartya Sen writes, "The Indian Emperor Ashoka in the third century BCE presented many political inscriptions in favor of tolerance and individual freedom, both as a part of state policy and in the relation of different people to each other". However, the edicts alone strongly indicate that he was a Buddhist. In one edict he belittles rituals, and he banned Vedic animal sacrifices; these strongly suggest that he at least did not look to the Vedic tradition for guidance. Furthermore, many edicts are expressed to Buddhists alone; in one, Ashoka declares himself to be an "upasaka", and in another he demonstrates a close familiarity with Buddhist texts. He erected rock pillars at Buddhist holy sites, but did not do so for the sites of other religions. He also used the word "dhamma" to refer to qualities of the heart that underlie moral action; this was an exclusively Buddhist use of the word. However, he used the word more in the spirit than as a strict code of conduct. Romila Thappar writes, "His dhamma did not derive from divine inspiration, even if its observance promised heaven. It was more in keeping with the ethic conditioned by the logic of given situations. His logic of Dhamma was intended to influence the conduct of categories of people, in relation to each other. Especially where they involved unequal relationships." Finally, he promotes ideals that correspond to the first three steps of the Buddha's graduated discourse. Much of the knowledge about Ashoka comes from the several inscriptions that he had carved on pillars and rocks throughout the empire. All his inscriptions present him as compassionate and loving. In the Kalinga rock edits, he addresses his people as his "children" and mentions that as a father he desires their good. Impact of pacifism After Ashoka's death, the Maurya dynasty declined rapidly. The various Puranas provide different details about Ashoka's successors, but all agree that they had relatively short reigns. The empire seems to have weakened, fragmented, and suffered an invasion from the Bactrian Greeks. Some historians, such as H. C. Raychaudhuri, have argued that Ashoka's pacifism undermined the "military backbone" of the Maurya empire. Others, such as Romila Thapar, have suggested that the extent and impact of his pacifism have been "grossly exaggerated".

Analytical Engine

The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. In other words, the structure of the Analytical Engine was essentially the same as that which has dominated computer design in the electronic era. The Analytical Engine is one of the most successful achievements of Charles Babbage. Babbage was never able to complete construction of any of his machines due to conflicts with his chief engineer and inadequate funding. It was not until 1941 that Konrad Zuse built the first general-purpose computer, Z3, more than a century after Babbage had proposed the pioneering Analytical Engine in 1837. Design Babbage's first attempt at a mechanical computing device, the Difference Engine, was a special-purpose machine designed to tabulate logarithms and trigonometric functions by evaluating finite differences to create approximating polynomials. Construction of this machine was never completed; Babbage had conflicts with his chief engineer, Joseph Clement, and ultimately the British government withdrew its funding for the project. During this project, Babbage realised that a much more general design, the Analytical Engine, was possible. The work on the design of the Analytical Engine started around 1833. The input, consisting of programs ("formulae") and data, was to be provided to the machine via punched cards, a method being used at the time to direct mechanical looms such as the Jacquard loom. For output, the machine would have a printer, a curve plotter, and a bell. The machine would also be able to punch numbers onto cards to be read in later. It employed ordinary base-10 fixed-point arithmetic. There was to be a store (that is, a memory) capable of holding 1,000 numbers of 40 decimal digits each (ca. 16.6 kB). An arithmetic unit (the "mill") would be able to perform all four arithmetic operations, plus comparisons and optionally square roots. Initially (1838) it was conceived as a difference engine curved back upon itself, in a generally circular layout, with the long store exiting off to one side. Later drawings (1858) depict a regularised grid layout. Like the central processing unit (CPU) in a modern computer, the mill would rely upon its own internal procedures, to be stored in the form of pegs inserted into rotating drums called "barrels", to carry out some of the more complex instructions the user's program might specify. The programming language to be employed by users was akin to modern day assembly languages. Loops and conditional branching were possible, and so the language as conceived would have been Turing-complete as later defined by Alan Turing. Three different types of punch cards were used: one for arithmetical operations, one for numerical constants, and one for load and store operations, transferring numbers from the store to the arithmetical unit or back. There were three separate readers for the three types of cards. Babbage developed some two dozen programs for the Analytical Engine between 1837 and 1840, and one program later. These programs treat polynomials, iterative formulas, Gaussian elimination, and Bernoulli numbers. In 1842, the Italian mathematician Luigi Federico Menabrea published a description of the engine in French, based on lectures Babbage gave when he visited Turin in 1840. In 1843, the description was translated into English and extensively annotated by Ada Lovelace, who had become interested in the engine eight years earlier. In recognition of her additions to Menabrea's paper, which included a way to calculate Bernoulli numbers using the machine (widely considered to be the first complete computer program), she has been described as the first computer programmer. Construction Late in his life, Babbage sought ways to build a simplified version of the machine, and assembled a small part of it before his death in 1871. In 1878, a committee of the British Association for the Advancement of Science described the Analytical Engine as "a marvel of mechanical ingenuity", but recommended against constructing it. The committee acknowledged the usefulness and value of the machine, but could not estimate the cost of building it, and were unsure whether the machine would function correctly after being built. Intermittently from 1880 to 1910, Babbage's son Henry Prevost Babbage was constructing a part of the mill and the printing apparatus. In 1910, it was able to calculate a (faulty) list of multiples of pi. This constituted only a small part of the whole engine; it was not programmable and had no storage. (Popular images of this section have sometimes been mislabelled, implying that it was the entire mill or even the entire engine.) Henry Babbage's "Analytical Engine Mill" is on display at the Science Museum in London. Henry also proposed building a demonstration version of the full engine, with a smaller storage capacity: "perhaps for a first machine ten (columns) would do, with fifteen wheels in each". Such a version could manipulate 20 numbers of 25 digits each, and what it could be told to do with those numbers could still be impressive. "It is only a question of cards and time", wrote Henry Babbage in 1888, "... and there is no reason why (twenty thousand) cards should not be used if necessary, in an Analytical Engine for the purposes of the mathematician". In 1991, the London Science Museum built a complete and working specimen of Babbage's Difference Engine No. 2, a design that incorporated refinements Babbage discovered during the development of the Analytical Engine. This machine was built using materials and engineering tolerances that would have been available to Babbage, quelling the suggestion that Babbage's designs could not have been produced using the manufacturing technology of his time. In October 2010, John Graham-Cumming started a "Plan 28" campaign to raise funds by "public subscription" to enable serious historical and academic study of Babbage's plans, with a view to then build and test a fully working virtual design which will then in turn enable construction of the physical Analytical Engine. As of May 2016, actual construction had not been attempted, since no consistent understanding could yet be obtained from Babbage's original design drawings. In particular it was unclear whether it could handle the indexed variables which were required for Lovelace's Bernoulli program. By 2017, the "Plan 28" effort reported that a searchable database of all catalogued material was available, and an initial review of Babbage's voluminous Scribbling Books had been completed. Many of Babbage's original drawings have been digitised and are publicly available online. Instruction set Babbage is not known to have written down an explicit set of instructions for the engine in the manner of a modern processor manual. Instead he showed his programs as lists of states during their execution, showing what operator was run at each step with little indication of how the control flow would be guided. Allan G. Bromley has assumed that the card deck could be read in forwards and backwards directions as a function of conditional branching after testing for conditions, which would make the engine Turing-complete: ...the cards could be ordered to move forward and reverse (and hence to loop)... The introduction for the first time, in 1845, of user operations for a variety of service functions including, most importantly, an effective system for user control of looping in user programs. There is no indication how the direction of turning of the operation and variable cards is specified. In the absence of other evidence I have had to adopt the minimal default assumption that both the operation and variable cards can only be turned backward as is necessary to implement the loops used in Babbage's sample programs. There would be no mechanical or microprogramming difficulty in placing the direction of motion under the control of the user. In their emulator of the engine, Fourmilab say: The Engine's Card Reader is not constrained to simply process the cards in a chain one after another from start to finish. It can, in addition, directed by the very cards it reads and advised by whether the Mill's run-up lever is activated, either advance the card chain forward, skipping the intervening cards, or backward, causing previously-read cards to be processed once again. This emulator does provide a written symbolic instruction set, though this has been constructed by its authors rather than based on Babbage's original works. For example, a factorial program would be written as: N0 6 N1 1 N2 1 × L1 L0 S1 – L0 L2 S0 L2 L0 CB?11 where the CB is the conditional branch instruction or "combination card" used to make the control flow jump, in this case backward by 11 cards. Influence Predicted influence Babbage understood that the existence of an automatic computer would kindle interest in the field now known as algorithmic efficiency, writing in his Passages from the Life of a Philosopher, "As soon as an Analytical Engine exists, it will necessarily guide the future course of the science. Whenever any result is sought by its aid, the question will then arise—By what course of calculation can these results be arrived at by the machine in the shortest time?" Computer science From 1872 Henry continued diligently with his father's work and then intermittently in retirement in 1875. Percy Ludgate wrote about the engine in 1914 and published his own design for an Analytical Engine in 1909. It was drawn up in detail, but never built, and the drawings have never been found. Ludgate's engine would be much smaller (about , which corresponds to cube of side length ) than Babbage's, and hypothetically would be capable of multiplying two 20-decimal-digit numbers in about six seconds. In his Essays on Automatics (1913) Leonardo Torres y Quevedo, inspired by Babbage, designed a theoretical electromechanical calculating machine which was to be controlled by a read-only program. The paper also contains the idea of floating-point arithmetic. Vannevar Bush's paper Instrumental Analysis (1936) included several references to Babbage's work. In the same year he started the Rapid Arithmetical Machine project to investigate the problems of constructing an electronic digital computer. Despite this groundwork, Babbage's work fell into historical obscurity, and the Analytical Engine was unknown to builders of electromechanical and electronic computing machines in the 1930s and 1940s when they began their work, resulting in the need to re-invent many of the architectural innovations Babbage had proposed. Howard Aiken, who built the quickly-obsoleted electromechanical calculator, the Harvard Mark I, between 1937 and 1945, praised Babbage's work likely as a way of enhancing his own stature, but knew nothing of the Analytical Engine's architecture during the construction of the Mark I, and considered his visit to the constructed portion of the Analytical Engine "the greatest disappointment of my life". The Mark I showed no influence from the Analytical Engine and lacked the Analytical Engine's most prescient architectural feature, conditional branching. J. Presper Eckert and John W. Mauchly similarly were not aware of the details of Babbage's Analytical Engine work prior to the completion of their design for the first electronic general-purpose computer, the ENIAC. Comparison to other early computers If the Analytical Engine had been built, it would have been digital, programmable and Turing-complete. It would, however, have been very slow. Luigi Federico Menabrea reported in Sketch of the Analytical Engine: "Mr. Babbage believes he can, by his engine, form the product of two numbers, each containing twenty figures, in three minutes". By comparison the Harvard Mark I could perform the same task in just six seconds. A modern PC can do the same thing in well under a billionth of a second. In popular culture The cyberpunk novelists William Gibson and Bruce Sterling co-authored a steampunk novel of alternative history titled The Difference Engine in which Babbage's difference and Analytical Engines became available to Victorian society. The novel explores the consequences and implications of the early introduction of computational technology. Moriarty by Modem, a short story by Jack Nimersheim, describes an alternative history where Babbage's Analytical Engine was indeed completed and had been deemed highly classified by the British government. The characters of Sherlock Holmes and Moriarty had in reality been a set of prototype programs written for the Analytical Engine. This short story follows Holmes as his program is implemented on modern computers and he is forced to compete against his nemesis yet again in the modern counterparts of Babbage's Analytical Engine. A similar setting is used by Sydney Padua in the webcomic The Thrilling Adventures of Lovelace and Babbage. It features an alternative history where Ada Lovelace and Babbage have built the Analytical Engine and use it to fight crime at Queen Victoria's request. The comic is based on thorough research on the biographies of and correspondence between Babbage and Lovelace, which is then twisted for humorous effect. The Orion's Arm online project features the Machina Babbagenseii, fully sentient Babbage-inspired mechanical computers. Each is the size of a large asteroid, only capable of surviving in microgravity conditions, and processes data at 0.5% the speed of a human brain.

Antarctic Treaty System

The Antarctic Treaty and related agreements, collectively known as the Antarctic Treaty System (ATS), regulate international relations with respect to Antarctica, Earth's only continent without a native human population. It was the first arms control agreement established during the Cold War, setting aside the continent as a scientific preserve, establishing freedom of scientific investigation, and banning military activity; for the purposes of the treaty system, Antarctica is defined as all the land and ice shelves south of 60°S latitude. Since September 2004, the Antarctic Treaty Secretariat, which implements the treaty system, is headquartered in Buenos Aires, Argentina. The main treaty was opened for signature on December 1, 1959, and officially entered into force on June 23, 1961. The original signatories were the 12 countries active in Antarctica during the International Geophysical Year (IGY) of 1957–58: Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the Soviet Union, the United Kingdom, and the United States. These countries had established over 55 Antarctic research stations for the IGY, and the subsequent promulgation of the treaty was seen as a diplomatic expression of the operational and scientific cooperation that had been achieved. , the treaty has 56 parties. History 1940s After the Second World War, the U.S. considered establishing a claim in Antarctica. From August 26, 1946, and until the beginning of 1947, it carried out Operation Highjump, the largest military expeditionary force that the United States had ever sent to Antarctica, consisting of 13 ships, 4,700 men, and numerous aerial devices. Its goals were to train military personnel and to test materiel in conditions of extreme cold for a hypothetical war in the Antarctic. On September 2, 1947, the quadrant of Antarctica in which the United States was interested (between 24° W and 90° W) was included as part of the security zone of the Inter-American Treaty of Reciprocal Assistance, committing its members to defend it in case of external aggression. In August 1948, the United States proposed that Antarctica be under the guardianship of the United Nations, as a trust territory administered by Argentina, Australia, Chile, France, the United States, the United Kingdom, and New Zealand. This idea was rejected by Argentina, Australia, Chile, France, and Norway. Before the rejection, on August 28, 1948, the United States proposed to the claimant countries some form of internationalization of Antarctica, and this was supported by the United Kingdom. Chile responded by presenting a plan to suspend all Antarctic claims for five to ten years, while negotiating a final solution, but this did not find acceptance. In 1950, the interest of the United States to keep the Soviet Union away from Antarctica was frustrated, when the Soviets informed the claimant states that they would not accept any Antarctic agreement in which they were not represented. The fear that the USSR would react by making a territorial claim, bringing the Cold War to Antarctica, led the United States to make none. International conflicts Various international conflicts motivated the creation of an agreement for the Antarctic. Some incidents had occurred during the Second World War, and a new one occurred in Hope Bay on February 1, 1952, when the Argentine military fired warning shots at a group of Britons. The response of the United Kingdom was to send a warship that landed marines at the scene on February 4. In 1949, Argentina, Chile, and the United Kingdom signed a Tripartite Naval Declaration committing not to send warships south of the 60th parallel south, which was renewed annually until 1961 when it was deemed unnecessary when the treaty entered into force. This tripartite declaration was signed after the tension generated when Argentina sent a fleet of eight warships to Antarctica in February 1948. On January 17, 1953, Argentina reopened the Lieutenant Lasala refuge on Deception Island, leaving a sergeant and a corporal in the Argentine Navy. On February 15, in the incident on Deception Island, 32 royal marines landed from the British frigate HMS Snipe armed with Sten machine guns, rifles, and tear gas capturing the two Argentine sailors. The Argentine refuge and a nearby uninhabited Chilean shelter were destroyed, and the Argentine sailors were delivered to a ship from that country on February 18 near South Georgia. A British detachment remained three months on the island while the frigate patrolled its waters until April. On May 4, 1955, the United Kingdom filed two lawsuits, against Argentina and Chile respectively, before the International Court of Justice to declare the invalidity of the claims of the sovereignty of the two countries over Antarctic and sub-Antarctic areas. On July 15, 1955, the Chilean government rejected the jurisdiction of the court in that case, and on August 1, the Argentine government also did so, so on March 16, 1956, the claims were closed. In 1956 and 1958, India tried unsuccessfully to bring the Antarctic issue to the United Nations General Assembly. International Geophysical Year In 1950, the International Council of Scientific Unions (ICSU) had discussed the possibility of holding a third International Polar Year. At the suggestion of the World Meteorological Organization, the idea of the International Polar Year was extended to the entire planet, thus creating the International Geophysical Year that took place between July 1, 1957, and December 31, 1958. In this event, 66 countries participated. At the ICSU meeting in Stockholm from September 9 to 11, 1957, the creation of a Special Committee for Antarctic Research (SCAR) was approved, inviting the twelve countries conducting Antarctic investigations to send delegates to integrate the committee, with the purpose of exchanging scientific information among its members regarding Antarctica. The SCAR was later renamed to the Scientific Committee for Research in Antarctica. Both Argentina and Chile stated that research carried out on the continent during the International Geophysical Year would not give any territorial rights to the participants, and that the facilities that were erected during that year should be dismantled at the end of it. However, in February 1958, the United States proposed that the Antarctic investigations should be extended for another year, and the Soviet Union reported that it would maintain its scientific bases until the studies being carried out had been completed. Negotiation of the treaty Scientific bases increased international tension concerning Antarctica. The danger of the Cold War spreading to that continent caused the President of the United States, Dwight D. Eisenhower, to convene an Antarctic Conference of the twelve countries active in Antarctica during the International Geophysical Year, to sign a treaty. In the first phase, representatives of the twelve nations met in Washington, who met in sixty sessions between June 1958 and October 1959 to define a basic negotiating framework. However, no consensus was reached on a preliminary draft. In the second phase, a conference at the highest diplomatic level was held from October 15 to December 1, 1959, when the Treaty was signed. The central ideas with full acceptance were the freedom of scientific research in Antarctica and the peaceful use of the continent. There was also a consensus for demilitarization and the maintenance of the status quo. The positions of the United States, the Soviet Union, the United Kingdom, and New Zealand coincided in the establishment of an international administration for Antarctica, proposing that it should be within the framework of the United Nations. Australia and the United Kingdom expressed the need for inspections by observers, and the British also proposed the use of military personnel for logistical functions. Argentina proposed that all atomic explosions be banned in Antarctica, which caused a crisis that lasted until the last day of the conference, since the United States, along with other countries, intended to ban only those that were made without prior notice and without prior consultation. The support of the USSR and Chile for the Argentine proposal finally caused the United States to retract its opposition. The signing of the treaty was the first arms control agreement that occurred in the framework of the Cold War, and the participating countries managed to avoid the internationalization of Antarctic sovereignty. Other agreements Other agreements – some 200 recommendations adopted at treaty consultative meetings and ratified by governments – include: Agreed Measures for the Conservation of Antarctic Fauna and Flora (1964) (entered into force in 1982) The Convention for the Conservation of Antarctic Seals (1972) The Convention for the Conservation of Antarctic Marine Living Resources (1982) The Convention on the Regulation of Antarctic Mineral Resource Activities (1988) (signed in 1988, not in force) The Protocol on Environmental Protection to the Antarctic Treaty was signed October 4, 1991, and entered into force January 14, 1998; this agreement prevents development and provides for the protection of the Antarctic environment through five specific annexes on marine pollution, fauna and flora, environmental impact assessments, waste management, and protected areas. It prohibits all activities relating to mineral resources except scientific. A sixth annex on liability arising from environmental emergencies was adopted in 2005, but is yet to enter into force. Bilateral treaties Exchange of Notes constituting an Agreement between the Governments of Australia, New Zealand and the United Kingdom of Great Britain and Northern Ireland, and the Government of the French Republic, regarding Aerial Navigation in the Antarctic (Paris, October 25, 1938) Treaty Between the Government of Australia and the Government of the French Republic on Cooperation in the Maritime Areas Adjacent to the French Southern and Antarctic Territories (TAAF), Heard Island and the McDonald Islands (Canberra, November 24, 2003) Agreement on Cooperative Enforcement of Fisheries Laws between the Government of Australia and the Government of the French Republic in the Maritime Areas Adjacent to the French Southern and Antarctic Territories, Heard Island and the McDonald Islands (Paris, January 8, 2007) Meetings The Antarctic Treaty System's yearly Antarctic Treaty Consultative Meetings (ATCM) are the international forum for the administration and management of the region. Only 29 of the 56 parties to the agreements have the right to participate in decision-making at these meetings, though the other 27 are still allowed to attend. The decision-making participants are the Consultative Parties and, in addition to the 12 original signatories, including 17 countries that have demonstrated their interest in Antarctica by carrying out substantial scientific activity there. The Antarctic Treaty also has Special Antarctic Treaty Consultative Meetings (SATCM), which are generally summoned to treat more important topics but are less frequents and Meetings of Experts. Parties As of 2023, there are 56 states party to the treaty, 29 of which, including all 12 original signatories to the treaty, have consultative (voting) status. The consultative members include the 7 countries that claim portions of Antarctica as their territory. The 49 non-claimant countries do not recognize the claims of others. 42 parties to the Antarctic Treaty have also ratified the "Protocol on Environmental Protection to the Antarctic Treaty". * Has an overlapping claim with another one or two claimants. † Reserved the right to make a claim. Antarctic Treaty Secretariat The Antarctic Treaty Secretariat was established in Buenos Aires, Argentina in September 2004 by the Antarctic Treaty Consultative Meeting (ATCM). Jan Huber (the Netherlands) served as the first Executive Secretary for five years until August 31, 2009. He was succeeded on September 1, 2009, by Manfred Reinke (Germany). Reinke was succeeded by Albert Lluberas (Uruguay), who was elected in June 2017 at the 40th Antarctic Consultative Treaty Meeting in Beijing, China. The tasks of the Antarctic Treaty Secretariat can be divided into the following areas: Supporting the annual Antarctic Treaty Consultative Meeting (ATCM) and the meeting of the Committee for Environmental Protection (CEP). Facilitating the exchange of information between the Parties required in the Treaty and the Environment Protocol. Collecting, storing, arranging and publishing the documents of the ATCM. Providing and disseminating public information about the Antarctic Treaty system and Antarctic activities. Legal system Antarctica currently has no permanent population and therefore it has no citizenship nor government. Personnel present on Antarctica at any time are always citizens or nationals of some sovereignty outside Antarctica, as there is no Antarctic sovereignty. The majority of Antarctica is claimed by one or more countries, but most countries do not explicitly recognize those claims. The area on the mainland between 90 degrees west and 150 degrees west is the only major land on Earth not claimed by any country. Until 2015 the interior of the Norwegian Sector, the extent of which had never been officially defined, was considered to be unclaimed. That year, Norway formally laid claim to the area between its Queen Maud Land and the South Pole. Governments that are party to the Antarctic Treaty and its Protocol on Environmental Protection implement the articles of these agreements, and decisions taken under them, through national laws. These laws generally apply only to their own citizens, wherever they are in Antarctica, and serve to enforce the consensus decisions of the consultative parties: about which activities are acceptable, which areas require permits to enter, what processes of environmental impact assessment must precede activities, and so on. The Antarctic Treaty is often considered to represent an example of the common heritage of mankind principle. Australia Since the designation of the Australian Antarctic Territory pre-dated the signing of the Antarctic Treaty, Australian laws that relate to Antarctica date from more than two decades before the Antarctic Treaty era. In terms of criminal law, the laws that apply to the Jervis Bay Territory (which follows the laws of the Australian Capital Territory) apply to the Australian Antarctic Territory. Key Australian legislation applying Antarctic Treaty System decisions include the Antarctic Treaty Act 1960, the Antarctic Treaty (Environment Protection) Act 1980 and the Antarctic Marine Living Resources Conservation Act 1981. United States The law of the United States, including certain criminal offences by or against U.S. nationals, such as murder, may apply to areas not under jurisdiction of other countries. To this end, the United States now stations special deputy U.S. Marshals in Antarctica to provide a law enforcement presence. Some U.S. laws directly apply to Antarctica. For example, the Antarctic Conservation Act, Public Law 95-541, et seq., provides civil and criminal penalties for the following activities, unless authorized by regulation or statute: the taking of native Antarctic mammals or birds the introduction into Antarctica of non-indigenous plants and animals entry into specially protected or scientific areas the discharge or disposal of pollutants into Antarctica or Antarctic waters the importation into the U.S. of certain items from Antarctica Violation of the Antarctic Conservation Act carries penalties of up to US$10,000 in fines and one year in prison. The Departments of the Treasury, Commerce, Transportation, and the Interior share enforcement responsibilities. The Act requires expeditions from the U.S. to Antarctica to notify, in advance, the Office of Oceans and Polar Affairs of the State Department, which reports such plans to other nations as required by the Antarctic Treaty. Further information is provided by the Office of Polar Programs of the National Science Foundation. New Zealand In 2006, the New Zealand police reported that jurisdictional issues prevented them issuing warrants for potential American witnesses who were reluctant to testify during the Christchurch Coroner's investigation into the death by poisoning of Australian astrophysicist Rodney Marks at the South Pole base in May 2000. Dr. Marks died while wintering over at the United States' Amundsen–Scott South Pole Station located at the geographic South Pole. Prior to autopsy, the death was attributed to natural causes by the National Science Foundation and the contractor administering the base. However, an autopsy in New Zealand revealed that Dr. Marks died from methanol poisoning. The New Zealand Police launched an investigation. In 2006, frustrated by lack of progress, the Christchurch Coroner said that it was unlikely that Dr. Marks ingested the methanol knowingly, although there is no certainty that he died as the direct result of the act of another person. During media interviews, the police detective in charge of the investigation criticized the National Science Foundation and contractor Raytheon for failing to co-operate with the investigation. South Africa Under the South African Citizens in Antarctica Act, 1962, South African law applies to all South African citizens in Antarctica, and they are subject to the jurisdiction of the magistrate's court in Cape Town. The Antarctic Treaties Act, 1996 incorporates the Antarctic Treaty and related agreements into South African law. In regard to violations of these treaties, South Africa also asserts jurisdiction over South African residents and members of expeditions organised in South Africa.

Alfred Lawson

Alfred William Lawson (March 24, 1869 – November 29, 1954) was an English born professional baseball player, aviator and utopian philosopher. He was a baseball player, manager, and league promoter from 1887 through 1916 and went on to play a pioneering role in the U.S. aircraft industry. He published two early aviation trade journals. He is frequently cited as the inventor of the airliner and was awarded several of the first air mail contracts, which he ultimately could not fulfill. He founded the Lawson Aircraft Company in Green Bay, Wisconsin, to build military training aircraft and later the Lawson Airplane Company in South Milwaukee, Wisconsin, to build airliners. The crash of his ambitious Lawson L-4 "Midnight Liner" during its trial flight takeoff on May 8, 1921, ended his best chance for commercial aviation success. In 1904, he wrote a utopian novel, Born Again, in which he developed the philosophy which later became Lawsonomy. Baseball career (1888–1907) He made one start for the Boston Beaneaters and two for the Pittsburgh Alleghenys during the 1890 season. His minor league playing career lasted through 1895. He later managed in the minors from 1905 to 1907. Union Professional League In 1908, he started a new professional baseball league known as the Union Professional League. The league took the field in April but folded one month later owing to financial difficulties. Aviation career (1908–1928) An early advocate or rather evangelist of aviation, in October 1908 Lawson started the magazine Fly to stimulate public interest and educate readers in the fundamentals of the new science of aviation. It sold for 10 cents a copy from newsstands across the country. In 1910, moving to New York City, he renamed the magazine Aircraft and published it until 1914. The magazine chronicled the technical developments of the early aviation pioneers. Lawson was the first advocate for commercial air travel, coining the term "airline." He also advocated for a strong American flying force, lobbying Congress in 1913 to expand its appropriations for Army aircraft. In early 1913, he learned to fly the Sloan-Deperdussin and the Moisant-Bleriot monoplanes, becoming an accomplished pilot. Later that year he bought a Thomas flying boat and became the first air commuter regularly flying from his country house in Seidler's Beach, New Jersey, to the foot of 75th Street in New York City (about 35 miles). In 1917, utilizing the knowledge gained from ten years of advocating aviation, he built his first airplane, the Lawson Military Tractor 1 (MT-1) trainer, and founded the Lawson Aircraft Corporation. The company's plant was sited at Green Bay, Wisconsin. There he secured a contract and built the Lawson MT-2. He also designed the steel fuselage Lawson Armored Battler, which never got beyond the drafting board, given doubts within the Army aviation community and the signing of the armistice. After the war, in 1919 Lawson started a project to build America's first airline. He secured financial backing, and in five months he had built and demonstrated in flight his biplane airliner, the 18-passenger Lawson L-2. He demonstrated its capabilities in a 2000-mile multi-city tour from Milwaukee to Chicago-Toledo-Cleveland-Buffalo-Syracuse-New york City-Washington, D.C.-Collinsville-Dayton-Chicago and back to Milwaukee, creating a buzz of positive press. The publicity allowed him to secure an additional $1 million to build the 26-passenger Midnight Liner. The aircraft crashed on takeoff on its maiden flight. In late 1920, he secured government contracts for three airmail routes and to deliver ten war planes, but owing to the fall 1920 recession, he could not secure the necessary $100,000 in cash reserves called for in the contracts and had to decline them. In 1926, he started his last airliner, the 56-seat, two-tier Lawson super airliner. In this phase of his life, he was considered one of the leading thinkers in the budding American commercial aviation community, but his troubles with getting financial backing for his ideas led him to turn to economics, philosophy, and organization. Lawsonomy (1929–1954) In the 1920s, Lawson promoted health practices, including vegetarianism, and claimed to have found the secret of living to 200. He also developed his own highly unusual theories of physics, according to which such concepts as "penetrability", "suction and pressure" and "zig-zag-and-swirl" were discoveries on par with Einstein's theory of relativity. He published numerous books on these concepts, all set in a distinctive typography. He later propounded his own philosophy, Lawsonomy, and the Lawsonian religion. He also developed, during the Great Depression, the populist economic theory of "Direct Credits", according to which banks are the cause of all economic woes, the oppressors of both capital and labour. Lawson believed that the government should replace banks as the provider of loans to business and workers. He predicted the worldwide adoption of Lawsonian principles once "everybody understands this subject". His rallies and lectures attracted thousands of listeners in the early 1930s, mainly in the upper Midwest, but by the late 1930s the crowds had dwindled. His claims about his own greatness became increasingly hyperbolic. The Lawsonomy trilogy, considered by Lawson himself to be his intellectual masterpiece, is full of such self-referential statements as "About every two thousand years a new teacher with advanced intellectual equipment appears upon earth to lead the people a step or two nearer the one God of everybody". In 1943, he founded the Humanity Benefactor Foundation and University of Lawsonomy in Des Moines, on the site of Des Moines University, to spread his teachings and offer the degree of "Knowledgian", but after various IRS and other investigations it was closed and finally sold in 1954, the year of Lawson's death. His financial arrangements remain mysterious to this day, and in later years he seems to have owned little property, moving from city to city as a guest of his farflung acolytes. In 1952, he was brought before a United States Senate investigative committee on allegations that his organization had bought war surplus machines and then sold them for a profit, despite claiming non-profit status. His attempt to explain Lawsonomy to the senators ended in mutual frustration and bafflement. A farm near Racine, Wisconsin, is the only remaining university facility, although a tiny handful of churches may yet survive in places such as Wichita, Kansas. The large sign, formerly reading "University of Lawsonomy", was a familiar landmark for motorists in the region for many years and was visible from Interstate 94 about north of the Illinois state line, on the east side of the highway. A storm in the spring of 2009 destroyed the sign, although the supporting posts are still visible. On the northbound side of Interstate 94, a sign on the roof of the building nearest the freeway said "Study Natural Law" until being shingled over in October 2014. In 2018, the Town of Mount Pleasant paid $933,000 to purchase the property on the northbound side of Interstate 94 for the Foxconn project. All remaining buildings were demolished and removed. Lawsonomy maintains a small following to this day. See also List of topics characterized as pseudoscience References Further reading Henry, Lyell D. Zig-Zag-and Swirl: Alfred W.

Andes

The Andes, Andes Mountains or Andean Mountain Range (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest mountain range outside Asia. The highest mountain outside Asia, Argentina's Mount Aconcagua, rises to an elevation of about above sea level. The peak of Chimborazo in the Ecuadorian Andes is farther from the Earth's center than any other location on the Earth's surface, due to the equatorial bulge resulting from the Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border, which rises to . The Andes are also part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica. Etymology The etymology of the word Andes has been debated. The majority consensus is that it derives from the Quechua word 'east' as in Antisuyu (Quechua for 'east region'), one of the four regions of the Inca Empire. The term cordillera comes from the Spanish word cordel 'rope' and is used as a descriptive name for several contiguous sections of the Andes, as well as the entire Andean range, and the combined mountain chain along the western part of the North and South American continents. Geography The Andes can be divided into three sections: The Southern Andes in Argentina and Chile, south of Llullaillaco. The Central Andes in Peru and Bolivia. The Northern Andes in Venezuela, Colombia, and Ecuador. In the northern part of the Andes, the separate Sierra Nevada de Santa Marta range is often treated as part of the Northern Andes. The Leeward Antilles islands Aruba, Bonaire, and Curaçao, which lie in the Caribbean Sea off the coast of Venezuela, were formerly thought to represent the submerged peaks of the extreme northern edge of the Andes range, but ongoing geological studies indicate that such a simplification does not do justice to the complex tectonic boundary between the South American and Caribbean plates. Geology The Andes are a Mesozoic–Tertiary orogenic belt of mountains along the Pacific Ring of Fire, a zone of volcanic activity that encompasses the Pacific rim of the Americas as well as the Asia-Pacific region. The Andes are the result of tectonic plate processes, caused by the subduction of oceanic crust beneath the South American Plate as the Nazca Plate and South American Plate converge. These processes were accelerated by the effects of climate. As the uplift of the Andes created a rain shadow on the western fringes of Chile, ocean currents and prevailing winds carried moisture away from the Chilean coast. This caused some areas of the subduction zone to be sediment starved, causing excess friction and an increased rate of compressed coastal uplift. The main cause of the rise of the Andes is the compression of the western rim of the South American Plate due to the subduction of the Nazca Plate and the Antarctic Plate.To the east, the Andes range is bounded by several sedimentary basins, such as Orinoco, Amazon Basin, Madre de Dios and Gran Chaco, that separate the Andes from the ancient cratons in eastern South America. In the south, the Andes share a long boundary with the former Patagonia Terrane. To the west, the Andes end at the Pacific Ocean, although the Peru-Chile trench can be considered their ultimate western limit. From a geographical approach, the Andes are considered to have their western boundaries marked by the appearance of coastal lowlands and a less rugged topography. The Andes Mountains also contain large quantities of iron ore located in many mountains within the range. The Andean orogen has a series of bends or oroclines. The Bolivian Orocline is a seaward concave bending in the coast of South America and the Andes Mountains at about 18° S. At this point, the orientation of the Andes turns from Northwest in Peru to South in Chile and Argentina. The Andean segment north and south of the Orocline have been rotated 15° to 20° counter clockwise and clockwise respectively. The Bolivian Orocline area overlaps with the area of maximum width of the Altiplano Plateau and according to Isacks (1988) the Orocline is related to crustal shortening. The specific point at 18° S where the coastline bends is known as the "Arica Elbow". Further south lies the Maipo Orocline a more subtle Orocline between 30° S and 38°S with a seaward-concave break in trend at 33° S. Near the southern tip of the Andes lies the Patagonian Orocline. Orogeny The western rim of the South American Plate has been the place of several pre-Andean orogenies since at least the late Proterozoic and early Paleozoic, when several terranes and microcontinents collided and amalgamated with the ancient cratons of eastern South America, by then the South American part of Gondwana. The formation of the modern Andes began with the events of the Triassic when Pangaea began the break up that resulted in developing several rifts. The development continued through the Jurassic Period. It was during the Cretaceous Period that the Andes began to take their present form, by the uplifting, faulting and folding of sedimentary and metamorphic rocks of the ancient cratons to the east. The rise of the Andes has not been constant, as different regions have had different degrees of tectonic stress, uplift, and erosion. Tectonic forces above the subduction zone along the entire west coast of South America where the Nazca Plate and a part of the Antarctic Plate are sliding beneath the South American Plate continue to produce an ongoing orogenic event resulting in minor to major earthquakes and volcanic eruptions to this day. In the extreme south, a major transform fault separates Tierra del Fuego from the small Scotia Plate. Across the wide Drake Passage lie the mountains of the Antarctic Peninsula south of the Scotia Plate which appear to be a continuation of the Andes chain. The regions immediately east of the Andes experience a series of changes resulting from the Andean orogeny. Parts of the Sunsás Orogen in Amazonian craton disappeared from the surface of earth being overridden by the Andes. The Sierras de Córdoba, where the effects of the ancient Pampean orogeny can be observed, owe their modern uplift and relief to the Andean orogeny in the Tertiary. Further south in southern Patagonia the onset of the Andean orogeny caused the Magallanes Basin to evolve from being an extensional back-arc basin in the Mesozoic to being a compressional foreland basin in the Cenozoic. Volcanism The Andes range has many active volcanoes distributed in four volcanic zones separated by areas of inactivity. The Andean volcanism is a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones that are separated from each other by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products and morphology. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences inside volcanic zones and even between neighbouring volcanoes. Despite being a type location for calc-alkalic and subduction volcanism, the Andean Volcanic Belt has a large range of volcano-tectonic settings, such as rift systems and extensional zones, transpressional faults, subduction of mid-ocean ridges and seamount chains apart from a large range of crustal thicknesses and magma ascent paths, and different amount of crustal assimilations. Ore deposits and evaporates The Andes Mountains host large ore and salt deposits and some of their eastern fold and thrust belt acts as traps for commercially exploitable amounts of hydrocarbons. In the forelands of the Atacama Desert some of the largest porphyry copper mineralizations occur making Chile and Peru the first- and second-largest exporters of copper in the world. Porphyry copper in the western slopes of the Andes has been generated by hydrothermal fluids (mostly water) during the cooling of plutons or volcanic systems. The porphyry mineralization further benefited from the dry climate that let them largely out of the disturbing actions of meteoric water. The dry climate in the central western Andes has also led to the creation of extensive saltpeter deposits which were extensively mined until the invention of synthetic nitrates. Yet another result of the dry climate are the salars of Atacama and Uyuni, the first one being the largest source of lithium today and the second the world's largest reserve of the element. Early Mesozoic and Neogene plutonism in Bolivia's Cordillera Central created the Bolivian tin belt as well as the famous, now depleted, deposits of Cerro Rico de Potosí. History The Andes Mountains, initially inhabited by hunter-gatherers, experienced the development of agriculture and rise of politically centralised civilizations, which culminated in the establishment of the century-long Inca Empire. This all changed in the 16th century, when the Spanish conquistadors colonized the mountains in the advance of the mining economy. In tide of anti-imperialist nationalism, the Andes became the scene of a series of independence wars in the 19th century when rebel forces swept through the region to overthrow Spanish colonial rule. Since then, many former Spanish territories have become five independent Andean states. Climate and hydrology The climate in the Andes varies greatly depending on latitude, altitude, and proximity to the sea. Temperature, atmospheric pressure and humidity decrease in higher elevations. The southern section is rainy and cool, the central section is dry. The northern Andes are typically rainy and warm, with an average temperature of in Colombia. The climate is known to change drastically in rather short distances. Rainforests exist just kilometres away from the snow-covered peak Cotopaxi. The mountains have a large effect on the temperatures of nearby areas. The snow line depends on the location. It is at between in the tropical Ecuadorian, Colombian, Venezuelan, and northern Peruvian Andes, rising to in the drier mountains of southern Peru south to northern Chile south to about 30°S before descending to on Aconcagua at 32°S, at 40°S, at 50°S, and only in Tierra del Fuego at 55°S; from 50°S, several of the larger glaciers descend to sea level. The Andes of Chile and Argentina can be divided into two climatic and glaciological zones: the Dry Andes and the Wet Andes. Since the Dry Andes extend from the latitudes of Atacama Desert to the area of Maule River, precipitation is more sporadic and there are strong temperature oscillations. The line of equilibrium may shift drastically over short periods of time, leaving a whole glacier in the ablation area or in the accumulation area. In the high Andes of Central Chile and Mendoza Province, rock glaciers are larger and more common than glaciers; this is due to the high exposure to solar radiation. In these regions glaciers occur typically at higher altitudes than rock glaciers. The lowest active rock glacier occur at 900 m a.s.l. in Aconcagua. Though precipitation increases with the height, there are semiarid conditions in the nearly highest mountains of the Andes. This dry steppe climate is considered to be typical of the subtropical position at 32–34° S. The valley bottoms have no woods, just dwarf scrub. The largest glaciers, for example the Plomo glacier and the Horcones glaciers, do not even reach in length and have an only insignificant ice thickness. At glacial times, however, c. 20,000 years ago, the glaciers were over ten times longer. On the east side of this section of the Mendozina Andes, they flowed down to and on the west side to about above sea level. The massifs of Cerro Aconcagua (), Cerro Tupungato () and Nevado Juncal () are tens of kilometres away from each other and were connected by a joint ice stream network. The Andes' dendritic glacier arms, i.e. components of valley glaciers, were up to long, over thick and overspanned a vertical distance of . The climatic glacier snowline (ELA) was lowered from to at glacial times. Flora The Andean region cuts across several natural and floristic regions, due to its extension, from Caribbean Venezuela to cold, windy and wet Cape Horn passing through the hyperarid Atacama Desert. Rainforests and tropical dry forests used to encircle much of the northern Andes but are now greatly diminished, especially in the Chocó and inter-Andean valleys of Colombia. Opposite of the humid Andean slopes are the relatively dry Andean slopes in most of western Peru, Chile and Argentina. Along with several Interandean Valles, they are typically dominated by deciduous woodland, shrub and xeric vegetation, reaching the extreme in the slopes near the virtually lifeless Atacama Desert. About 30,000 species of vascular plants live in the Andes, with roughly half being endemic to the region, surpassing the diversity of any other hotspot. The small tree Cinchona pubescens, a source of quinine which is used to treat malaria, is found widely in the Andes as far south as Bolivia. Other important crops that originated from the Andes are tobacco and potatoes. The high-altitude Polylepis forests and woodlands are found in the Andean areas of Colombia, Ecuador, Peru, Bolivia and Chile. These trees, by locals referred to as Queñua, Yagual and other names, can be found at altitudes of above sea level. It remains unclear if the patchy distribution of these forests and woodlands is natural, or the result of clearing which began during the Incan period. Regardless, in modern times the clearance has accelerated, and the trees are now considered to be highly endangered, with some believing that as little as 10% of the original woodland remains. Fauna The Andes are rich in fauna: With almost 1,000 species, of which roughly 2/3 are endemic to the region, the Andes are the most important region in the world for amphibians. The diversity of animals in the Andes is high, with almost 600 species of mammals (13% endemic), more than 1,700 species of birds (about 1/3 endemic), more than 600 species of reptile (about 45% endemic), and almost 400 species of fish (about 1/3 endemic). The vicuña and guanaco can be found living in the Altiplano, while the closely related domesticated llama and alpaca are widely kept by locals as pack animals and for their meat and wool. The crepuscular (active during dawn and dusk) chinchillas, two threatened members of the rodent order, inhabit the Andes' alpine regions. The Andean condor, the largest bird of its kind in the Western Hemisphere, occurs throughout much of the Andes but generally in very low densities. Other animals found in the relatively open habitats of the high Andes include the huemul, cougar, foxes in the genus Pseudalopex, and, for birds, certain species of tinamous (notably members of the genus Nothoprocta), Andean goose, giant coot, flamingos (mainly associated with hypersaline lakes), lesser rhea, Andean flicker, diademed sandpiper-plover, miners, sierra-finches and diuca-finches. Lake Titicaca hosts several endemics, among them the highly endangered Titicaca flightless grebe and Titicaca water frog. A few species of hummingbirds, notably some hillstars, can be seen at altitudes above , but far higher diversities can be found at lower altitudes, especially in the humid Andean forests ("cloud forests") growing on slopes in Colombia, Ecuador, Peru, Bolivia and far northwestern Argentina. These forest-types, which includes the Yungas and parts of the Chocó, are very rich in flora and fauna, although few large mammals exist, exceptions being the threatened mountain tapir, spectacled bear and yellow-tailed woolly monkey. Birds of humid Andean forests include mountain-toucans, quetzals and the Andean cock-of-the-rock, while mixed species flocks dominated by tanagers and furnariids commonly are seen – in contrast to several vocal but typically cryptic species of wrens, tapaculos and antpittas. A number of species such as the royal cinclodes and white-browed tit-spinetail are associated with Polylepis, and consequently also threatened. Human activity The Andes Mountains form a north–south axis of cultural influences. A long series of cultural development culminated in the expansion of the Inca civilization and Inca Empire in the central Andes during the 15th century. The Incas formed this civilization through imperialistic militarism as well as careful and meticulous governmental management. The government sponsored the construction of aqueducts and roads in addition to preexisting installations. Some of these constructions are still in existence today. Devastated by European diseases and by civil war, the Incas were defeated in 1532 by an alliance composed of tens of thousands of allies from nations they had subjugated (e.g. Huancas, Chachapoyas, Cañaris) and a small army of 180 Spaniards led by Francisco Pizarro. One of the few Inca sites the Spanish never found in their conquest was Machu Picchu, which lay hidden on a peak on the eastern edge of the Andes where they descend to the Amazon. The main surviving languages of the Andean peoples are those of the Quechua and Aymara language families. Woodbine Parish and Joseph Barclay Pentland surveyed a large part of the Bolivian Andes from 1826 to 1827. Cities In modern times, the largest cities in the Andes are Bogotá, with a metropolitan population of over ten million, and Santiago, Medellín, Cali, and Quito. Lima is a coastal city adjacent to the Andes and is the largest city of all Andean countries. It is the seat of the Andean Community of Nations. La Paz, Bolivia's seat of government, is the highest capital city in the world, at an elevation of approximately . Parts of the La Paz conurbation, including the city of El Alto, extend up to . Other cities in or near the Andes include Bariloche, Catamarca, Jujuy, Mendoza, Salta, San Juan, Tucumán, and Ushuaia in Argentina; Calama and Rancagua in Chile; Cochabamba, Oruro, Potosí, Sucre, Sacaba, Tarija, and Yacuiba in Bolivia; Arequipa, Cajamarca, Cusco, Huancayo, Huánuco, Huaraz, Juliaca, and Puno in Peru; Ambato, Cuenca, Ibarra, Latacunga, Loja, Riobamba and Tulcán in Ecuador; Armenia, Cúcuta, Bucaramanga, Duitama, Ibagué, Ipiales, Manizales, Palmira, Pasto, Pereira, Popayán, Sogamoso, Tunja, and Villavicencio in Colombia; and Barquisimeto, La Grita, Mérida, San Cristóbal, Tovar, Trujillo, and Valera in Venezuela. The cities of Caracas, Valencia, and Maracay are in the Venezuelan Coastal Range, which is a debatable extension of the Andes at the northern extremity of South America. Transportation Cities and large towns are connected with asphalt-paved roads, while smaller towns are often connected by dirt roads, which may require a four-wheel-drive vehicle. The rough terrain has historically put the costs of building highways and railroads that cross the Andes out of reach of most neighboring countries, even with modern civil engineering practices. For example, the main crossover of the Andes between Argentina and Chile is still accomplished through the Paso Internacional Los Libertadores. Only recently the ends of some highways that came rather close to one another from the east and the west have been connected. Much of the transportation of passengers is done via aircraft. However, there is one railroad that connects Chile with Peru via the Andes, and there are others that make the same connection via southern Bolivia. See railroad maps of that region. There are multiple highways in Bolivia that cross the Andes. Some of these were built during a period of war between Bolivia and Paraguay, in order to transport Bolivian troops and their supplies to the war front in the lowlands of southeastern Bolivia and western Paraguay. For decades, Chile claimed ownership of land on the eastern side of the Andes. However, these claims were given up in about 1870 during the War of the Pacific between Chile and the allied Bolivia and Peru, in a diplomatic deal to keep Peru out of the war. The Chilean Army and Chilean Navy defeated the combined forces of Bolivia and Peru, and Chile took over Bolivia's only province on the Pacific Coast, some land from Peru that was returned to Peru decades later. Bolivia has been a completely landlocked country ever since. It mostly uses seaports in eastern Argentina and Uruguay for international trade because its diplomatic relations with Chile have been suspended since 1978. Because of the tortuous terrain in places, villages and towns in the mountains—to which travel via motorized vehicles is of little use—are still located in the high Andes of Chile, Bolivia, Peru, and Ecuador. Locally, the relatives of the camel, the llama, and the alpaca continue to carry out important uses as pack animals, but this use has generally diminished in modern times. Donkeys, mules, and horses are also useful. Agriculture The ancient peoples of the Andes such as the Incas have practiced irrigation techniques for over 6,000 years. Because of the mountain slopes, terracing has been a common practice. Terracing, however, was only extensively employed after Incan imperial expansions to fuel their expanding realm. The potato holds a very important role as an internally consumed staple crop. Maize was also an important crop for these people, and was used for the production of chicha, important to Andean native people. Currently, tobacco, cotton and coffee are the main export crops. Coca, despite eradication programmes in some countries, remains an important crop for legal local use in a mildly stimulating herbal tea, and, both controversially and illegally, for the production of cocaine. Irrigation In unirrigated land, pasture is the most common type of land use. In the rainy season (summer), part of the rangeland is used for cropping (mainly potatoes, barley, broad beans and wheat). Irrigation is helpful in advancing the sowing data of the summer crops which guarantees an early yield in the period of food shortage. Also, by early sowing, maize can be cultivated higher up in the mountains (up to ). In addition, it makes cropping in the dry season (winter) possible and allows the cultivation of frost-resistant vegetable crops like onion and carrot. Mining The Andes rose to fame for their mineral wealth during the Spanish conquest of South America. Although Andean Amerindian peoples crafted ceremonial jewelry of gold and other metals, the mineralizations of the Andes were first mined on a large scale after the Spanish arrival. Potosí in present-day Bolivia and Cerro de Pasco in Peru were among the principal mines of the Spanish Empire in the New World. Río de la Plata and Argentina derive their names from the silver of Potosí. Currently, mining in the Andes of Chile and Peru places these countries as the first and second major producers of copper in the world. Peru also contains the 4th largest goldmine in the world: the Yanacocha. The Bolivian Andes produce principally tin although historically silver mining had a huge impact on the economy of 17th century Europe. There is a long history of mining in the Andes, from the Spanish silver mines in Potosí in the 16th century to the vast current porphyry copper deposits of Chuquicamata and Escondida in Chile and Toquepala in Peru. Other metals including iron, gold, and tin in addition to non-metallic resources are important. Peaks This list contains some of the major peaks in the Andes mountain range.

https://en.wikipedia.org/wiki/Anagram

Anagram

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For example, the word anagram itself can be rearranged into nag a ram, as well as the word binary into brainy and the word adobe into abode. The original word or phrase is known as the subject of the anagram. Any word or phrase that exactly reproduces the letters in another order is an anagram. Someone who creates anagrams may be called an "anagrammatist", and the goal of a serious or skilled anagrammatist is to produce anagrams that reflect or comment on their subject. Examples Anagrams may be created as a commentary on the subject. They may be a parody, a criticism or satire. For example: "New York Times" = "monkeys write" "Church of Scientology" = "rich-chosen goofy cult" "McDonald's restaurants" = "Uncle Sam's standard rot" "coronavirus" = "carnivorous" "She Sells Sanctuary" = "Santa; shy, less cruel" or "Satan; cruel, less shy" An anagram may also be a synonym of the original word. For example: "evil" = "vile" "a gentleman" = "elegant man" "eleven plus two" = "twelve plus one" An anagram that has a meaning opposed to that of the original word or phrase is called an "antigram". For example: "restful" = "fluster" "cheater" = "teacher" "funeral" = "real fun" "adultery" = "true lady" "forty five" = "over fifty" "Santa" = "Satan" They can sometimes change from a proper noun or personal name into an appropriate sentence: "William Shakespeare" = "I am a weakish speller" "Madam Curie" = "Radium came" "George Bush" = "He bugs Gore" "Tom Marvolo Riddle" = "I am Lord Voldemort" They can change part of speech, such as the adjective "silent" to the verb "listen". "Anagrams" itself can be anagrammatized as "Ars magna" (Latin, 'the great art'). History Anagrams can be traced back to the time of the ancient Greeks, and were used to find the hidden and mystical meaning in names. They were popular throughout Europe during the Middle Ages, for example with the poet and composer Guillaume de Machaut. They are said to date back at least to the Greek poet Lycophron, in the third century BCE; but this relies on an account of Lycophron given by John Tzetzes in the 12th century. In the Talmudic and Midrashic literature, anagrams were used to interpret the Hebrew Bible, notably by Eleazar of Modi'im. Later, Kabbalists took this up with enthusiasm, calling anagrams temurah. Anagrams in Latin were considered witty over many centuries. Est vir qui adest, explained below, was cited as the example in Samuel Johnson's A Dictionary of the English Language. They became hugely popular in the early modern period, especially in Germany. Any historical material on anagrams must always be interpreted in terms of the assumptions and spellings that were current for the language in question. In particular, spelling in English only slowly became fixed. There were attempts to regulate anagram formation, an important one in English being that of George Puttenham's Of the Anagram or Posy Transposed in The Art of English Poesie (1589). Influence of Latin As a literary game when Latin was the common property of the literate, Latin anagrams were prominent. Two examples are the change of Ave Maria, gratia plena, Dominus tecum (Latin: Hail Mary, full of grace, the Lord [is] with you) into Virgo serena, pia, munda et immaculata (Latin: Serene virgin, pious, clean and spotless), and the anagrammatic answer to Pilate's question, Quid est veritas? (Latin: What is truth?), namely, Est vir qui adest (Latin: It is the man who is here). The origins of these are not documented. Latin continued to influence letter values (such as I = J, U = V and W = VV). There was an ongoing tradition of allowing anagrams to be "perfect" if the letters were all used once, but allowing for these interchanges. This can be seen in a popular Latin anagram against the Jesuits: Societas Jesu turned into Vitiosa seces (Latin: Cut off the wicked things). Puttenham, in the time of Elizabeth I, wished to start from Elissabet Anglorum Regina (Latin: Elizabeth Queen of the English), to obtain Multa regnabis ense gloria (Latin: By thy sword shalt thou reign in great renown); he explains carefully that H is "a note of aspiration only and no letter", and that Z in Greek or Hebrew is a mere SS. The rules were not completely fixed in the 17th century. William Camden in his Remains commented, singling out some letters—Æ, K, W, and Z—not found in the classical Roman alphabet: Early modern period When it comes to the 17th century and anagrams in English or other languages, there is a great deal of documented evidence of learned interest. The lawyer Thomas Egerton was praised through the anagram gestat honorem ('he carries honor'); the physician George Ent took the anagrammatic motto genio surget ('he rises through spirit/genius'), which requires his first name as Georgius. James I's courtiers discovered in "James Stuart" "a just master", and converted "Charles James Stuart" into "Claims Arthur's seat" (even at that point in time, the letters I and J were more-or-less interchangeable). Walter Quin, tutor to the future Charles I, worked hard on multilingual anagrams on the name of father James. A notorious murder scandal, the Overbury case, threw up two imperfect anagrams that were aided by typically loose spelling and were recorded by Simonds D'Ewes: "Francis Howard" (for Frances Carr, Countess of Somerset, her maiden name spelled in a variant) became "Car findes a whore", with the letters E hardly counted, and the victim Thomas Overbury, as "Thomas Overburie", was written as "O! O! a busie murther" (an old form of "murder"), with a V counted as U. William Drummond of Hawthornden, in an essay On the Character of a Perfect Anagram, tried to lay down rules for permissible substitutions (such as S standing for Z) and letter omissions. William Camden provided a definition of "Anagrammatisme" as "a dissolution of a name truly written into his letters, as his elements, and a new connection of it by artificial transposition, without addition, subtraction or change of any letter, into different words, making some perfect sense appliable (i.e., applicable) to the person named." Dryden in MacFlecknoe disdainfully called the pastime the "torturing of one poor word ten thousand ways". "Eleanor Audeley", wife of Sir John Davies, is said to have been brought before the High Commission in 1634 for extravagances, stimulated by the discovery that her name could be transposed to "Reveale, O Daniel", and to have been laughed out of court by another anagram submitted by Sir John Lambe, the dean of the Arches, "Dame Eleanor Davies", "Never soe mad a ladie". An example from France was a flattering anagram for Cardinal Richelieu, comparing him to Hercules or at least one of his hands (Hercules being a kingly symbol), where Armand de Richelieu became Ardue main d'Hercule ("difficult hand of Hercules"). Modern period Examples from the 19th century are the transposition of "Horatio Nelson" into Honor est a Nilo (Latin: Honor is from the Nile); and of "Florence Nightingale" into "Flit on, cheering angel". The Victorian love of anagramming as recreation is alluded to by the mathematician Augustus De Morgan using his own name as an example; "Great Gun, do us a sum!" is attributed to his son William De Morgan, but a family friend John Thomas Graves was prolific, and a manuscript with over 2,800 has been preserved. With the advent of surrealism as a poetic movement, anagrams regained the artistic respect they had had in the Baroque period. The German poet Unica Zürn, who made extensive use of anagram techniques, came to regard obsession with anagrams as a "dangerous fever", because it created isolation of the author. The surrealist leader André Breton coined the anagram Avida Dollars for Salvador Dalí, to tarnish his reputation by the implication of commercialism. Applications While anagramming is certainly a recreation first, there are ways in which anagrams are put to use, and these can be more serious, or at least not quite frivolous and formless. For example, psychologists use anagram-oriented tests, often called "anagram solution tasks", to assess the implicit memory of young adults and adults alike. Establishment of priority Natural philosophers (astronomers and others) of the 17th century transposed their discoveries into Latin anagrams, to establish their priority. In this way they laid claim to new discoveries before their results were ready for publication. Galileo used for (Latin: I have observed the most distant planet to have a triple form) for discovering the rings of Saturn in 1610. Galileo announced his discovery that Venus had phases like the Moon in the form (Latin: These immature ones have already been read in vain by me -oy), that is, when rearranged, (Latin: The Mother of Loves [= Venus] imitates the figures of Cynthia [= the moon]). In both cases, Johannes Kepler had solved the anagrams incorrectly, assuming they were talking about the Moons of Mars () and a red spot on Jupiter (), respectively. By coincidence, he turned out to be right about the actual objects existing. In 1656, Christiaan Huygens, using a better telescope than those available to Galileo, figured that Galileo's earlier observations of Saturn actually meant it had a ring (Galileo's tools were only sufficient to see it as bumps) and, like Galileo, had published an anagram, . Upon confirming his observations, three years later he revealed it to mean (Latin: It [Saturn] is surrounded by a thin, flat, ring, nowhere touching, inclined to the ecliptic). When Robert Hooke discovered Hooke's law in 1660, he first published it in anagram form, , for (Latin: as the extension, so the force). Pseudonyms Anagrams are connected to pseudonyms, by the fact that they may conceal or reveal, or operate somewhere in between like a mask that can establish identity. For example, Jim Morrison used an anagram of his name in the Doors song "L.A. Woman", calling himself "Mr. Mojo Risin'". The use of anagrams and fabricated personal names may be to circumvent restrictions on the use of real names, as happened in the 18th century when Edward Cave wanted to get around restrictions imposed on the reporting of the House of Commons. In a genre such as farce or parody, anagrams as names may be used for pointed and satiric effect. Pseudonyms adopted by authors are sometimes transposed forms of their names; thus "Calvinus" becomes "Alcuinus" (here V = U) or "François Rabelais" = "Alcofribas Nasier". The name "Voltaire" of François Marie Arouet fits this pattern, and is allowed to be an anagram of "Arouet, l[e] j[eune]" (U = V, J = I) that is, "Arouet the younger". Other examples include: "Damon Albarn" = "Dan Abnormal" "Dave Barry" = "Ray Adverb" "Arrigo Boito" = "Tobia Gorrio" "Buckethead" = "Death Cube K" "Daniel Clowes" = "Enid Coleslaw" "Siobhán Donaghy" = "Shanghai Nobody" "Glen Duncan" = "Declan Gunn" "(Theodor) Geisel" = "(Theo) Le Sieg" "Edward Gorey" = "Ogdred Weary", = "Regera Dowdy" or = "E. G. Deadworry" (and others) "Anna Madrigal" = "A man and a girl" "Ted Morgan" = "(Sanche) de Gramont" "Lorin Morgan-Richards" = "Marcil d'Hirson Garron" "Vladimir Nabokov" = "Vivian Darkbloom", = "Vivian Bloodmark", = "Blavdak Vinomori", or = "Dorian Vivalkomb" Several of these are "imperfect anagrams", letters having been left out in some cases for the sake of easy pronunciation. Titles Anagrams used for titles afford scope for some types of wit. Examples: Homer Hickam Jr.'s book Rocket Boys was adapted into the 1999 film October Sky. The tapes for the revival of the BBC show Doctor Who were labeled with the anagram Torchwood, which later went on to be used as the name for a spin-off show. In multi-episode shows, the program occasionally substitutes the anagram of an actor's name for the actual name to prevent revealing the true identity of the role (for instance, The Master) being played by the actor. The New Wave band Missing Persons' best-selling album was called Spring Session M. Hip-hop artist MF Doom recorded a 2004 album called Mm..Food. Brian Eno's album Before and After Science includes a song entitled "King's Lead Hat", an anagram of "Talking Heads", a band Eno has worked with. Juan Maria Solare's piano ballad "Jura ser anomalía" (literally "he/she swears to be an anomaly") is an anagram of the composer's full name. His composition for English horn titled "A Dot in Time" is an anagram of "Meditation", which describes the piece. The title of his piano piece that is a homage to Claude Debussy is "Seduce Us Badly". Bill Evans's overdubbed piano elegy for fellow jazz pianist Sonny Clark is titled "N.Y.C.'s No Lark," and another composition, "Re: Person I Knew" is a tribute to his producer, Orrin Keepnews. The title of Imogen Heap's album iMegaphone is an anagram of her name. Progressive rock group Rush published a song on their 1989 album Presto titled "Anagram (for Mongo)" that makes use of anagrams in every line of the song. The title of the fifth album by American rock band Interpol, El Pintor, is an anagram of the band's name and also Spanish for "the painter". Many of the song titles on Aphex Twin's ...I Care Because You Do are anagrams of either "Aphex Twin", "The Aphex Twin", or "Richard D. James". In Disney's 1964 film Mary Poppins, Dick Van Dyke played Mr. Dawes Sr. as the anagram of his name, Navckid Keyd. In the credits, the words unscrambled themselves to reveal his name. The title of King Crimson's 1982 song Thela Hun Ginjeet is an anagram of "heat in the jungle". Two albums released in 2022 by Australian rock band King Gizzard & the Lizard Wizard titled "Made in Timeland" and "Laminated Denim". Coincidences In Hebrew, the name "Gernot Zippe" (גרנוט ציפה), the inventor of the Zippe-type centrifuge, is an anagram of the word "centrifuge" (צנטריפוגה). The sentence "Name is Anu Garg", referring to anagrammer and founder of wordsmith.org Anu Garg, can be rearranged to spell "Anagram genius". Games and puzzles Anagrams are in themselves a recreational activity, but they also make up part of many other games, puzzles and game shows. The Jumble is a puzzle found in many newspapers in the United States requiring the unscrambling of letters to find the solution. Cryptic crossword puzzles frequently use anagrammatic clues, usually indicating that they are anagrams by the inclusion of a descriptive term like "confused" or "in disarray". An example would be Businessman burst into tears (9 letters). The solution, stationer, is an anagram of into tears, the letters of which have burst out of their original arrangement to form the name of a type of businessman. Numerous other games and contests involve some element of anagram formation as a basic skill. Some examples: In Anagrams, players flip tiles over one at a time and race to take words. They can "steal" each other's words by rearranging the letters and extending the words. In a version of Scrabble called Clabbers, the name itself is an anagram of Scrabble. Tiles may be placed in any order on the board as long as they anagram to a valid word. On the British game show Countdown, contestants are given 30 seconds to make the longest word from nine random letters. In Boggle, players make constrained words from a grid of sixteen random letters, by joining adjacent cubes. On the British game show BrainTeaser, contestants are shown a word broken into randomly arranged segments and must announce the whole word. At the end of the game there is a "Pyramid" which starts with a three-letter word. A letter appears in the line below to which the player must add the existing letters to find a solution. The pattern continues until the player reaches the final eight-letter anagram. The player wins the game by solving all the anagrams within the allotted time. In Bananagrams, players place tiles from a pool into crossword-style word arrangements in a race to see who can finish the pool of tiles first. Ciphers Multiple anagramming is a technique used to solve some kinds of cryptograms, such as a permutation cipher, a transposition cipher, and the Jefferson disk. Solutions may be computationally found using a Jumble algorithm. Methods of construction Sometimes, it is possible to "see" anagrams in words, unaided by tools, though the more letters involved the more difficult this becomes. The difficulty is that for a word of different letters, there are (factorial of ) different permutations and so different anagrams of the word. Anagram dictionaries can also be used. Computer programs, known as "anagram search", "anagram servers", "anagram solvers", offer a much faster route to creating anagrams, and a large number of these programs are available on the Internet. Some programs use the Anatree algorithm to compute anagrams efficiently. The program or server carries out an exhaustive search of a database of words, to produce a list containing every possible combination of words or phrases from the input word or phrase using a jumble algorithm. Some programs (such as Lexpert) restrict to one-word answers. Many anagram servers (for example, The Words Oracle) can control the search results, by excluding or including certain words, limiting the number or length of words in each anagram, or limiting the number of results. Anagram solvers are often banned from online anagram games. The disadvantage of computer anagram solvers, especially when applied to multi-word anagrams, is their poor understanding of the meaning of the words they are manipulating. They usually cannot filter out meaningful or appropriate anagrams from large numbers of nonsensical word combinations. Some servers attempt to improve on this using statistical techniques that try to combine only words that appear together often. This approach provides only limited success since it fails to recognize ironic and humorous combinations. Some anagrammatists indicate the method they used. Anagrams constructed without the aid of a computer are noted as having been done "manually" or "by hand"; those made by utilizing a computer may be noted "by machine" or "by computer", or may indicate the name of the computer program (using Anagram Genius). There are also a few "natural" instances: English words unconsciously created by switching letters around. The French chaise longue ("long chair") became the American "chaise lounge" by metathesis (transposition of letters and/or sounds). It has also been speculated that the English "curd" comes from the Latin crudus ("raw"). Similarly, the ancient English word for bird was "brid". Prominent anagrammatists The French king Louis XIII had a man named Thomas Billon appointed as his Royal Anagrammatist with an annual salary of 1200 pounds. Among contemporary anagrammers, Anu Garg, created an Internet Anagram Server in 1994 together with the satirical anagram-based newspaper The Anagram Times. Mike Keith has anagrammed the complete text of Moby Dick. He, along with Richard Brodie, has published The Anagrammed Bible that includes anagrammed version of many books of the Bible. Popular television personality Dick Cavett is known for his anagrams of famous celebrities such as Alec Guinness and Spiro Agnew.

Army

An army, ground force or land force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or country. It may also include aviation assets by possessing an army aviation component. Within a national military force, the word army may also mean a field army. In some countries, such as France and China, the term "army", especially in its plural form "armies", has the broader meaning of armed forces as a whole, while retaining the colloquial sense of land forces. To differentiate the colloquial army from the formal concept of military force, the term is qualified, for example in France the land force is called Armée de terre, meaning Land Army, and the air and space force is called Armée de l'Air et de l’Espace, meaning Air and Space Army. The naval force, although not using the term "army", is also included in the broad sense of the term "armies" — thus the French Navy is an integral component of the collective French Armies (French Armed Forces) under the Ministry of the Armies. A similar pattern is seen in China, with the People's Liberation Army (PLA) being the overall military, the land force being the PLA Ground Force, and so forth for the PLA Air Force, the PLA Navy, and other branches. By convention, irregular military is understood in contrast to regular armies which grew slowly from personal bodyguards or elite militia. Regular in this case refers to standardized doctrines, uniforms, organizations, etc. Regular military can also refer to full-time status (standing army), versus reserve or part-time personnel. Other distinctions may separate statutory forces (established under laws such as the National Defence Act), from de facto "non-statutory" forces such as some guerrilla and revolutionary armies. Armies may also be expeditionary (designed for overseas or international deployment) or fencible (designed for – or restricted to – homeland defence). Structure Armies are always divided into various specialties, according to the mission, role, and training of individual units, and sometimes individual soldiers within a unit. Some of the groupings common to all armies include the following: Infantry Armoured forces Artillery Signal corps Military police Medical corps History India India's armies were among the first in the world. In the first recorded battle, the Battle of the Ten Kings, a Hindu Aryan king named Sudas defeated an alliance of ten kings and their supportive chieftains. During the Iron Age, the Maurya and Nanda Empires had the largest armies in the world, the peak being approximately over 600,000 Infantry, 30,000 Cavalry, 8,000 War-Chariots and 9,000 War Elephants not including tributary state allies. In the Gupta age, large armies of longbowmen were recruited to fight off invading horse archer armies. Elephants, pikemen and cavalry were other featured troops. In Rajput times, the main piece of equipment was iron or chain-mail armor, a round shield, either a curved blade or a straight sword, a chakra disc, and a katar dagger. China The states of China raised armies for at least 1000 years before the Spring and Autumn Annals. By the Warring States period, the crossbow had been perfected enough to become a military secret, with bronze bolts that could pierce any armor. Thus any political power of a state rested on the armies and their organization. China underwent political consolidation of the states of Han (韓), Wei (魏), Chu (楚), Yan (燕), Zhao (趙) and Qi (齊), until by 221 BCE, Qin Shi Huang (秦始皇帝), the first emperor of the Qin dynasty, attained absolute power. This first emperor of China could command the creation of a Terracotta Army to guard his tomb in the city of Xi'an (西安), as well as a realignment of the Great Wall of China to strengthen his empire against insurrection, invasion and incursion. Sun Tzu's The Art of War remains one of China's Seven Military Classics, even though it is two thousand years old. Since no political figure could exist without an army, measures were taken to ensure only the most capable leaders could control the armies. Civil bureaucracies (士大夫) arose to control the productive power of the states, and their military power. Sparta The Spartan Army was one of the earliest known professional armies. Boys were sent to a barracks at the age of seven or eight to train for becoming a soldier. At the age of thirty, they were released from the barracks and allowed to marry and have a family. After that, men devoted their lives to war until their retirement at the age of 60. The Spartan Army was largely composed of hoplites, equipped with arms and armor nearly identical to each other. Each hoplite bore the Spartan emblem and a scarlet uniform. The main pieces of this armor were a round shield, a spear and a helmet. Ancient Rome The Roman Army had its origins in the citizen army of the Republic, which was staffed by citizens serving mandatory duty for Rome. Reforms turned the army into a professional organization which was still largely filled by citizens, but these citizens served continuously for 25 years before being discharged. The Romans were also noted for making use of auxiliary troops, non-Romans who served with the legions and filled roles that the traditional Roman military could not fill effectively, such as light skirmish troops and heavy cavalry. After their service in the army they were made citizens of Rome and then their children were citizens also. They were also given land and money to settle in Rome. In the Late Roman Empire, these auxiliary troops, along with foreign mercenaries, became the core of the Roman Army; moreover, by the time of the Late Roman Empire tribes such as the Visigoths were paid to serve as mercenaries. Medieval Europe In the earliest Middle Ages it was the obligation of every aristocrat to respond to the call to battle with his own equipment, archers, and infantry. This decentralized system was necessary due to the social order of the time, but could lead to motley forces with variable training, equipment and abilities. The more resources the noble had access to, the better his troops would be. Initially, the words "knight" and "noble" were used interchangeably as there was not generally a distinction between them. While the nobility did fight upon horseback, they were also supported by lower class citizens – and mercenaries and criminals – whose only purpose was participating in warfare because, most often than not, they held brief employment during their lord's engagement. As the Middle Ages progressed and feudalism developed in a legitimate social and economic system, knights started to develop into their own class with a minor caveat: they were still in debt to their lord. No longer primarily driven by economic need, the newly established vassal class were, instead, driven by fealty and chivalry. As central governments grew in power, a return to the citizen armies of the classical period also began, as central levies of the peasantry began to be the central recruiting tool. England was one of the most centralized states in the Middle Ages, and the armies that fought in the Hundred Years' War were, predominantly, composed of paid professionals. In theory, every Englishman had an obligation to serve for forty days. Forty days was not long enough for a campaign, especially one on the continent. Thus the scutage was introduced, whereby most Englishmen paid to escape their service and this money was used to create a permanent army. However, almost all high medieval armies in Europe were composed of a great deal of paid core troops, and there was a large mercenary market in Europe from at least the early 12th century. As the Middle Ages progressed in Italy, Italian cities began to rely mostly on mercenaries to do their fighting rather than the militias that had dominated the early and high medieval period in this region. These would be groups of career soldiers who would be paid a set rate. Mercenaries tended to be effective soldiers, especially in combination with standing forces, but in Italy they came to dominate the armies of the city states. This made them considerably less reliable than a standing army. Mercenary-on-mercenary warfare in Italy also led to relatively bloodless campaigns which relied as much on maneuver as on battles. In 1439 the French legislature, known as the Estates General (French: états généraux), passed laws that restricted military recruitment and training to the king alone. There was a new tax to be raised known as the taille that was to provide funding for a new Royal army. The mercenary companies were given a choice of either joining the Royal army as compagnies d'ordonnance on a permanent basis, or being hunted down and destroyed if they refused. France gained a total standing army of around 6,000 men, which was sent out to gradually eliminate the remaining mercenaries who insisted on operating on their own. The new standing army had a more disciplined and professional approach to warfare than its predecessors. The reforms of the 1440s, eventually led to the French victory at Castillon in 1453, and the conclusion of the Hundred Years' War. By 1450 the companies were divided into the field army, known as the grande ordonnance and the garrison force known as the petite ordonnance. Early modern First nation states lacked the funds needed to maintain standing forces, so they tended to hire mercenaries to serve in their armies during wartime. Such mercenaries typically formed at the ends of periods of conflict, when men-at-arms were no longer needed by their respective governments. The veteran soldiers thus looked for other forms of employment, often becoming mercenaries. Free Companies would often specialize in forms of combat that required longer periods of training that was not available in the form of a mobilized militia. As late as the 1650s, most troops were mercenaries. However, after the 17th century, most states invested in better disciplined and more politically reliable permanent troops. For a time mercenaries became important as trainers and administrators, but soon these tasks were also taken by the state. The massive size of these armies required a large supporting force of administrators. The newly centralized states were forced to set up vast organized bureaucracies to manage these armies, which some historians argue is the basis of the modern bureaucratic state. The combination of increased taxes and increased centralization of government functions caused a series of revolts across Europe such as the Fronde in France and the English Civil War. In many countries, the resolution of this conflict was the rise of absolute monarchy. Only in England and the Netherlands did representative government evolve as an alternative. From the late 17th century, states learned how to finance wars through long term low interest loans from national banking institutions. The first state to master this process was the Dutch Republic. This transformation in the armies of Europe had great social impact. The defense of the state now rested on the commoners, not on the aristocrats. However, aristocrats continued to monopolize the officer corps of almost all early modern armies, including their high command. Moreover, popular revolts almost always failed unless they had the support and patronage of the noble or gentry classes. The new armies, because of their vast expense, were also dependent on taxation and the commercial classes who also began to demand a greater role in society. The great commercial powers of the Dutch and English matched much larger states in military might. As any man could be quickly trained in the use of a musket, it became far easier to form massive armies. The inaccuracy of the weapons necessitated large groups of massed soldiers. This led to a rapid swelling of the size of armies. For the first time huge masses of the population could enter combat, rather than just the highly skilled professionals. It has been argued that the drawing of men from across the nation into an organized corps helped breed national unity and patriotism, and during this period the modern notion of the nation state was born. However, this would only become apparent after the French Revolutionary Wars. At this time, the levée en masse and conscription would become the defining paradigm of modern warfare. Before then, however, most national armies were in fact composed of many nationalities. In Spain armies were recruited from all the Spanish European territories including Spain, Italy, Wallonia (Walloon Guards) and Germany. The French recruited some soldiers from Germany, Switzerland as well as from Piedmont. Britain recruited Hessian and Hanovrian troops until the late 18th century. Irish Catholics made careers for themselves in the armies of many Catholic European states. Prior to the English Civil War in England, the monarch maintained a personal bodyguard of Yeomen of the Guard and the Honourable Corps of Gentlemen at Arms, or "gentlemen pensioners", and a few locally raised companies to garrison important places such as Berwick on Tweed or Portsmouth (or Calais before it was recaptured by France in 1558). Troops for foreign expeditions were raised upon an ad hoc basis. Noblemen and professional regular soldiers were commissioned by the monarch to supply troops, raising their quotas by indenture from a variety of sources. On January 26, 1661 Charles II issued the Royal Warrant that created the genesis of what would become the British Army, although the Scottish and English Armies would remain two separate organizations until the unification of England and Scotland in 1707. The small force was represented by only a few regiments. After the American Revolutionary War the Continental Army was quickly disbanded as part of the Americans' distrust of standing armies, and irregular state militias became the sole ground army of the United States, with the exception of one battery of artillery guarding West Point's arsenal. Then First American Regiment was established in 1784. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army. The first of these, the Legion of the United States, was established in 1791. Until 1733 the common soldiers of Prussian Army consisted largely of peasantry recruited or impressed from Brandenburg–Prussia, leading many to flee to neighboring countries. To halt this trend, Frederick William I divided Prussia into regimental cantons. Every youth was required to serve as a soldier in these recruitment districts for three months each year; this met agrarian needs and added extra troops to bolster the regular ranks. Russian tsars before Peter I of Russia maintained professional hereditary musketeer corps (streltsy in Russian) that were highly unreliable and undisciplined. In times of war the armed forces were augmented by peasants. Peter I introduced a modern regular army built on German model, but with a new aspect: officers not necessarily from nobility, as talented commoners were given promotions that eventually included a noble title at the attainment of an officer's rank. Conscription of peasants and townspeople was based on quota system, per settlement. Initially it was based on the number of households, later it was based on the population numbers. The term of service in the 18th century was for life. In 1793 it was reduced to 25 years. In 1834 it was reduced to 20 years plus 5 years in reserve and in 1855 to 12 years plus 3 years of reserve. The first Ottoman standing army were Janissaries. They replaced forces that mostly comprised tribal warriors (ghazis) whose loyalty and morale could not always be trusted. The first Janissary units were formed from prisoners of war and slaves, probably as a result of the sultan taking his traditional one-fifth share of his army's booty in kind rather than cash. From the 1380s onwards, their ranks were filled under the devşirme system, where feudal dues were paid by service to the sultan. The "recruits" were mostly Christian youths, reminiscent of mamluks. China organized the Manchu people into the Eight Banner system in the early 17th century. Defected Ming armies formed the Green Standard Army. These troops enlisted voluntarily and for long terms of service. Late modern Conscription allowed the French Republic to form the Grande Armée, what Napoleon Bonaparte called "the nation in arms", which successfully battled European professional armies. Conscription, particularly when the conscripts are being sent to foreign wars that do not directly affect the security of the nation, has historically been highly politically contentious in democracies. In developed nations, the increasing emphasis on technological firepower and better-trained fighting forces, make mass conscription unlikely in the foreseeable future. Russia, as well as many other nations, retains mainly a conscript army. There is also a very rare citizen army as used in Switzerland (see Military of Switzerland). Field army A particular army can be named or numbered to distinguish it from military land forces in general. For example, the First United States Army and the Army of Northern Virginia. In the British Army it is normal to spell out the ordinal number of an army (e.g. First Army), whereas lower formations use figures (e.g. 1st Division). Armies (as well as army groups and theaters) are large formations which vary significantly between armed forces in size, composition, and scope of responsibility. In the Soviet Red Army and the Soviet Air Force, "Armies" could vary in size, but were subordinate to an Army Group-sized "front" in wartime. In peacetime, a Soviet army was usually subordinate to a military district. Viktor Suvorov's Inside the Soviet Army describes how Cold War era Soviet military districts were actually composed of a front headquarters and a military district headquarters co-located for administration and deception ('maskirovika') reasons. Formations In many countries, especially in Europe or North America, armies are often subdivided as follows: See also List of armies List of armies by country List of numbered armies List of countries by number of military and paramilitary personnel Military organization Paramilitary References External links Types of military forces

Alabaster

Alabaster is a mineral or rock that is soft, often used for carving, and is processed for plaster powder. Archaeologists and the stone processing industry use the word differently from geologists. The former use it in a wider sense that includes varieties of two different minerals: the fine-grained massive type of gypsum and the fine-grained banded type of calcite. Geologists define alabaster only as the gypsum type. Chemically, gypsum is a hydrous sulfate of calcium, while calcite is a carbonate of calcium. The two types of alabaster have similar properties. They are usually lightly colored, translucent, and soft stones. They have been used throughout history primarily for carving decorative artifacts. The calcite type is also denominated "onyx-marble", "Egyptian alabaster", and "Oriental alabaster" and is geologically described as either a compact banded travertine or "a stalagmitic limestone marked with patterns of swirling bands of cream and brown". "Onyx-marble" is a traditional, but geologically inaccurate, name because both onyx and marble have geological definitions that are distinct from even the broadest definition of "alabaster". In general, ancient alabaster is calcite in the wider Middle East, including Egypt and Mesopotamia, while it is gypsum in medieval Europe. Modern alabaster is probably calcite but may be either. Both are easy to work and slightly soluble in water. They have been used for making a variety of indoor artwork and carving, and they will not survive long outdoors. The two kinds are readily distinguished by their different hardnesses: gypsum alabaster (Mohs hardness 1.5 to 2) is so soft that a fingernail scratches it, while calcite (Mohs hardness 3) cannot be scratched in this way but yields to a knife. Moreover, calcite alabaster, being a carbonate, effervesces when treated with hydrochloric acid, while gypsum alabaster remains almost unaffected. Etymology The origin of "alabaster" is in Middle English through Old French "alabastre", in turn derived from Latin "alabaster", and that from Greek "ἀλάβαστρος" ("alabastros") or "ἀλάβαστος" ("alabastos"). The Greek words denoted a vase of alabaster. The name may be derived further from ancient Egyptian "a-labaste", which refers to vessels of the Egyptian goddess Bast. She was represented as a lioness and frequently depicted as such in figures placed atop these alabaster vessels. Ancient Roman authors, Pliny the Elder and Ptolemy, wrote that the stone used for ointment jars called alabastra came from a region of Egypt known as Alabastron or Alabastrites. Properties and usability The purest alabaster is a snow-white material of fine uniform grain, but it often is associated with an oxide of iron, which produces brown clouding and veining in the stone. The coarser varieties of gypsum alabaster are converted by calcination into plaster of Paris, and are sometimes known as "plaster stone". The softness of alabaster enables it to be carved readily into elaborate forms, but its solubility in water renders it unsuitable for outdoor work. If alabaster with a smooth, polished surface is washed with dishwashing liquid, it will become rough, dull and whiter, losing most of its translucency and lustre. The finer kinds of alabaster are employed largely as an ornamental stone, especially for ecclesiastical decoration and for the rails of staircases and halls. Modern processing Working techniques Alabaster is mined and then sold in blocks to alabaster workshops. There they are cut to the needed size ("squaring"), and then are processed in different techniques: turned on a lathe for round shapes, carved into three-dimensional sculptures, chiselled to produce low relief figures or decoration; and then given an elaborate finish that reveals its transparency, colour, and texture. Marble imitation In order to diminish the translucency of the alabaster and to produce an opacity suggestive of true marble, the statues are immersed in a bath of water and heated gradually—nearly to the boiling point—an operation requiring great care, because if the temperature is not regulated carefully, the stone acquires a dead-white, chalky appearance. The effect of heating appears to be a partial dehydration of the gypsum. If properly treated, it very closely resembles true marble and is known as "marmo di Castellina". Dyeing Alabaster is a porous stone and can be "dyed" into any colour or shade, a technique used for centuries. For this the stone needs to be fully immersed in various pigmentary solutions and heated to a specific temperature. The technique can be used to disguise alabaster. In this way a very misleading imitation of coral that is called "alabaster coral" is produced. Types, occurrence, history Typically only one type is sculpted in any particular cultural environment, but sometimes both have been worked to make similar pieces in the same place and time. This was the case with small flasks of the alabastron type made in Cyprus from the Bronze Age into the Classical period. Window panels When cut in thin sheets, alabaster is translucent enough to be used for small windows. It was used for this purpose in Byzantine churches and later in medieval ones, especially in Italy. Large sheets of Aragonese gypsum alabaster are used extensively in the contemporary Cathedral of Our Lady of the Angels, which was dedicated in 2002 by the Los Angeles, California Archdiocese. The cathedral incorporates special cooling to prevent the panes from overheating and turning opaque. The ancients used the calcite type, while the modern Los Angeles cathedral is using gypsum alabaster. There are also multiple examples of alabaster windows in ordinary village churches and monasteries in northern Spain. Calcite alabaster Calcite alabaster, harder than the gypsum variety, was the kind primarily used in ancient Egypt and the wider Middle East (but not Assyrian palace reliefs), and is also used in modern times. It is found as either a stalagmitic deposit from the floor and walls of limestone caverns, or as a kind of travertine, similarly deposited in springs of calcareous water. Its deposition in successive layers gives rise to the banded appearance that the marble often shows on cross-section, from which its name is derived: onyx-marble or alabaster-onyx, or sometimes simply (and wrongly) as onyx. Egypt and the Middle East Egyptian alabaster has been worked extensively near Suez and Assiut. This stone variety is the "alabaster" of the ancient Egyptians and Bible and is often termed Oriental alabaster, since the early examples came from the Far East. The Greek name alabastrites is said to be derived from the town of Alabastron in Egypt, where the stone was quarried. The locality probably owed its name to the mineral; the origin of the mineral name is obscure (though see above). The "Oriental" alabaster was highly esteemed for making small perfume bottles or ointment vases called alabastra; the vessel name has been suggested as a possible source of the mineral name. In Egypt, craftsmen used alabaster for canopic jars and various other sacred and sepulchral objects. The sarcophagus of Seti I, found in his tomb near Thebes, is on display in Sir John Soane's Museum, London; it is carved in a single block of translucent calcite alabaster from Alabastron. Algerian onyx-marble has been quarried largely in the province of Oran. Calcite alabaster was quarried in ancient Israel in the cave known today as the Twins Cave near Beit Shemesh. Herod used this alabaster for baths in his palaces. North America In Mexico, there are famous deposits of a delicate green variety at La Pedrara, in the district of Tecali, near Puebla. Onyx-marble occurs also in the district of Tehuacán and at several localities in the US including California, Arizona, Utah, Colorado and Virginia. Gypsum alabaster Gypsum alabaster is the softer of the two varieties, the other being calcite alabaster. It was used primarily in medieval Europe, and is also used in modern times. Ancient and Classical Near East "Mosul marble" is a kind of gypsum alabaster found in the north of modern Iraq, which was used for the Assyrian palace reliefs of the 9th to 7th centuries BC; these are the largest type of alabaster sculptures to have been regularly made. The relief is very low and the carving detailed, but large rooms were lined with continuous compositions on slabs around high. The Lion Hunt of Ashurbanipal and military Lachish reliefs, both 7th century and in the British Museum, are some of the best known. Gypsum alabaster was widely used for small sculpture for indoor use in the ancient world, especially in ancient Egypt and Mesopotamia. Fine detail could be obtained in a material with an attractive finish without iron or steel tools. Alabaster was used for vessels dedicated for use in the cult of the deity Bast in the culture of the ancient Egyptians, and thousands of gypsum alabaster artifacts dating to the late 4th millennium BC also have been found in Tell Brak (present day Nagar), in Syria. In Mesopotamia, gypsum alabaster was the material of choice for figures of deities and devotees in temples, as in a figure believed to represent the deity Abu dating to the first half of the 3rd millennium BC and currently kept in New York. Aragon, Spain Much of the world's alabaster extraction is performed in the centre of the Ebro Valley in Aragon, Spain, which has the world's largest known exploitable deposits. According to a brochure published by the Aragon government, alabaster has elsewhere either been depleted, or its extraction is so difficult that it has almost been abandoned or is carried out at a very high cost. There are two separate sites in Aragon, both are located in Tertiary basins. The most important site is the Fuentes-Azaila area, in the Tertiary Ebro Basin. The other is the Calatayud-Teruel Basin, which divides the Iberian Range in two main sectors (NW and SE). The abundance of Aragonese alabaster was crucial for its use in architecture, sculpture and decoration. There is no record of likely use by pre-Roman cultures, so perhaps the first ones to use alabaster in Aragon were the Romans, who produced vessels from alabaster following the Greek and Egyptian models. It seems that since the reconstruction of the Roman Wall in Zaragoza in the 3rd century AD with alabaster, the use of this material became common in building for centuries. Muslim Saraqusta (today, Zaragoza) was also called "Medina Albaida", the White City, due to the appearance of its alabaster walls and palaces, which stood out among gardens, groves and orchards by the Ebro and Huerva Rivers. The oldest remains in the Aljafería Palace, together with other interesting elements like capitals, reliefs and inscriptions, were made using alabaster, but it was during the artistic and economic blossoming of the Renaissance that Aragonese alabaster reached its golden age. In the 16th century sculptors in Aragon chose alabaster for their best works. They were adept at exploiting its lighting qualities and generally speaking the finished art pieces retained their natural color. Volterra (Tuscany) In Europe, the centre of the alabaster trade today is Florence, Italy. Tuscan alabaster occurs in nodular masses embedded in limestone, interstratified with marls of Miocene and Pliocene age. The mineral is worked largely by means of underground galleries, in the district of Volterra. Several varieties are recognized—veined, spotted, clouded, agatiform, and others. The finest kind, obtained principally from Castellina, is sent to Florence for figure-sculpture, while the common kinds are carved locally, into vases, lights, and various ornamental objects. These items are objects of extensive trade, especially in Florence, Pisa, and Livorno. In the 3rd century BC the Etruscans used the alabaster of Tuscany from the area of modern-day Volterra to produce funeral urns, possibly taught by Greek artists. During the Middle Ages the craft of alabaster was almost completely forgotten. A revival started in the mid-16th century, and until the beginning of the 17th century alabaster work was strictly artistic and did not expand to form a large industry. In the 17th and 18th centuries production of artistic, high-quality Renaissance-style artifacts stopped altogether, being replaced by less sophisticated, cheaper items better suited for large-scale production and commerce. The new industry prospered, but the reduced need of skilled craftsmen left only few still working. The 19th century brought a boom to the industry, largely due to the "traveling artisans" who went and offered their wares to the palaces of Europe, as well as to America and the East. In the 19th century new processing technology was also introduced, allowing for the production of custom-made, unique pieces, as well as the combination of alabaster with other materials. Apart from the newly developed craft, artistic work became again possible, chiefly by Volterran sculptor Albino Funaioli. After a short slump, the industry was revived again by the sale of mass-produced mannerist Expressionist sculptures, and was further enhanced in the 1920s by a new branch creating ceiling and wall lamps in the Art Deco style and culminating in the participation at the 1925 International Exposition of Modern Industrial and Decorative Arts from Paris. Important names from the evolution of alabaster use after World War II are Volterran Umberto Borgna, the "first alabaster designer", and later on the architect and industrial designer Angelo Mangiarotti. England and Wales Gypsum alabaster is a common mineral, which occurs in England in the Keuper marls of the Midlands, especially at Chellaston in Derbyshire, at Fauld in Staffordshire, and near Newark in Nottinghamshire. Deposits at all of these localities have been worked extensively. In the 14th and 15th centuries its carving into small statues and sets of relief panels for altarpieces was a valuable local industry in Nottingham, as well as a major English export. These were usually painted, or partly painted. It was also used for the effigies, often life size, on tomb monuments, as the typical recumbent position suited the material's lack of strength, and it was cheaper and easier to work than good marble. After the English Reformation the making of altarpiece sets was discontinued, but funerary monument work in reliefs and statues continued. Besides examples of these carvings still in Britain (especially at the Nottingham Castle Museum, British Museum, and Victoria and Albert Museum), trade in mineral alabaster (rather than just the antiques trade) has scattered examples in the material that may be found as far afield as the Musée de Cluny, Spain, and Scandinavia. Alabaster also is found, although in smaller quantity, at Watchet in Somerset, near Penarth in Glamorganshire, and elsewhere. In Cumbria it occurs largely in the New Red rocks, but at a lower geological horizon. The alabaster of Nottinghamshire and Derbyshire is found in thick nodular beds or "floors" in spheroidal masses known as "balls" or "bowls" and in smaller lenticular masses termed "cakes". At Chellaston, where the local alabaster is known as "Patrick", it has been worked into ornaments under the name of "Derbyshire spar"―a term more properly applied to fluorspar. Black alabaster Black alabaster is a rare anhydrite form of the gypsum-based mineral. This black form is found in only three veins in the world, one each in United States, Italy, and China. Alabaster Caverns State Park, near Freedom, Oklahoma is home to a natural gypsum cave in which much of the gypsum is in the form of alabaster. There are several types of alabaster found at the site, including pink, white, and the rare black alabaster.

Ahab

Ahab (; Aḫâbbu [a-ḫa-ab-bu]; Achaáb; ) was the seventh king of Israel, the son and successor of King Omri and the husband of Jezebel of Sidon, according to the Hebrew Bible. The Hebrew Bible presents Ahab as a wicked king, particularly for condoning Jezebel's influence on religious policies and his principal role behind Naboth's arbitrary execution. The existence of Ahab is historically supported outside the Bible. Shalmaneser III of Assyria documented in 853 BC that he defeated an alliance of a dozen kings in the Battle of Qarqar; one of these was Ahab. He is also mentioned on the inscriptions of the Mesha Stele. Ahab became king of Israel in the thirty-eighth year of King Asa of Judah, and reigned for twenty-two years, according to 1 Kings. William F. Albright dated his reign to 869–850 BC, while Edwin R. Thiele offered the dates 874–853 BC. Most recently, Michael Coogan has dated Ahab's reign to 871–852 BC. Reign King Omri, Ahab's father and founder of the short-lived Omri dynasty, seems to have been a successful military leader; he is reported in the text of the Moabite Mesha Stele to have "oppressed Moab for many days." During Ahab's reign, Moab, which had been conquered by his father, remained tributary. Ahab was allied by marriage with Jehoshaphat, who was king of Judah. Only with Aram-Damascus is he believed to have had strained relations, though the two kingdoms also shared an alliance for some years. Ahab married Jezebel, the daughter of the King of Tyre. tells the story of Ahab and Jezebel, and indicates that Jezebel was a dominant influence on Ahab, persuading him to abandon Yahweh and establish the religion of Baal in Israel. Ahab lived in Samaria, the royal capital established by Omri, and built a temple and altar to Baal there. These actions were said to have led to severe consequences for Israel, including a drought that lasted for several years and Jezebel's fanatical religious persecution of the prophets of Yahweh, which Ahab condoned. His reputation was so negative that in 1 Kings 16:34, the author attributed to his reign the deaths of Abiram and Segub, the sons of Hiel of Bethel, caused by their father's invocation of Joshua's curse several centuries before. According to , war later erupted between Ahab and king Hadadezer of Aram-Damascus (which the Bible refers to as "Ben-Hadad II") and that Ahab was able to defeat and capture him; however, soon after that, a peace treaty was made between the two and alliance between Israel and Aram-Damascus was formed. Battle of Qarqar The Battle of Qarqar is mentioned in extra-biblical records, and was perhaps at Apamea, where Shalmaneser III of Assyria fought a great confederation of princes from Cilicia, Northern Syria, Israel, Ammon, and the tribes of the Syrian desert (853 BCE), including Arabs, Ahab the Israelite (A-ha-ab-bu matSir-'a-la-a-a) and Hadadezer (Adad-'idri). Ahab's contribution was estimated at 2000 chariots and 10,000 men. In reality, however, the number of chariots in Ahab's forces was probably closer to a number in the hundreds (based upon archaeological excavations of the area and the foundations of stables that have been found). If, however, the numbers are referring to allies, they could possibly include forces from Tyre, Judah, Edom, and Moab. The Assyrian king claimed a victory, but his immediate return and subsequent expeditions in 849 BC and 846 BC against a similar but unspecified coalition seem to show that he met with no lasting success. Jezreel has been identified as Ahab's fortified chariot and cavalry base. Ahab and the prophets In the Biblical text, Ahab has five important encounters with prophets: The first encounter is with Elijah, who predicts a drought because of Ahab's sins. Because of this, Ahab refers to him as "the troubler of Israel" (1 Kings 18:17). This encounter ends with Elijah's victory over the prophets of Baal in a contest held for the sake of Ahab and the Israelites, to bring them into repentance. The second encounter is between Ahab and an unnamed prophet in . The third is again between Ahab and an unnamed prophet who condemns Ahab for his actions in a battle that had just taken place. The fourth is when Elijah confronts Ahab over his role in the unjust execution of Naboth and usurpation of the latter's ancestral vineyard. Upon the prophet's remonstration ("Hast thou killed and also taken possession?"), Ahab sincerely repented, which God relays to Elijah. The fifth encounter is with Micaiah, the prophet who, when asked for advice to recapturing Ramoth-Gilead, sarcastically assures Ahab that he will be successful. Micaiah ultimately tells him the truth of God's plan to kill Ahab in battle, due to his reliance on the false prophets, who were empowered by a deceiving spirit. Death of Ahab After some years, Ahab with Jehoshaphat of Judah went to recover Ramoth-Gilead from the Arameans. During this battle, Ahab disguised himself, but he was mortally wounded by an unaimed arrow. The Hebrew Bible says that dogs licked his blood, according to the prophecy of Elijah. But the Septuagint adds that pigs also licked his blood, symbolically making him unclean to the Israelites, who abstained from pork. Ahab was succeeded by his sons, Ahaziah and Jehoram. Jezebel's death, however, was more dramatic than Ahab's. As recorded in , Jehu had his servants throw Jezebel out of a window, causing her death. The dogs ate Jezebel's body, leaving nothing but her skull, her feet, and the palms of her hands, as prophesied by Elijah. Legacy 1 Kings 16:29 through 22:40 contains the narrative of Ahab's reign. His reign was slightly more emphasized upon than the previous kings, due to his blatant trivialization of the "sins of Jeroboam", which the previous kings of Israel were plagued by, and his subsequent marriage with a pagan princess, the nationwide institution of Baal worship, the persecution of Yahweh's prophets and Naboth's shocking murder. These offenses and atrocities stirred up populist resentment from figures such as Elijah and Micaiah. Indeed, he is referred to by the author of Kings as being "more evil than all the kings before him". Nonetheless, there were achievements that the author took note of, including his ability to fortify numerous Israelite cities and build an ivory palace. Adherents of the Yahwist religion found their principal champion in Elijah. His denunciation of the royal dynasty of Israel and his emphatic insistence on the worship of Yahweh and Yahweh alone, illustrated by the contest between Yahweh and Baal on Mount Carmel, form the keynote to a period that culminated in the accession of Jehu, an event in which Elijah's chosen disciple Elisha was the leading figure and the Omride Dynasty was brutally defeated. In Rabbinic literature Ahab was one of the three or four wicked kings of Israel singled out by tradition as being excluded from the future world of bliss (Sanh. x. 2; Tosef., Sanh. xii. 11). Midrash Konen places him in the fifth department of Gehenna, as having the heathen under his charge. Though held up as a warning to sinners, Ahab is also described as displaying noble traits of character (Sanh. 102b; Yer. Sanh. xi. 29b). Talmudic literature represents him as an enthusiastic idolater who left no hilltop in the Land of Israel without an idol before which he bowed, and to which he or his wife, Jezebel, brought his weight in gold as a daily offering. So defiant in his apostasy was he that he had inscribed on all the doors of the city of Samaria the words, "Ahab hath abjured the living God of Israel." Nevertheless, he paid great respect to the representatives of learning, "to the Torah given in twenty-two letters," for which reason he was permitted to reign for twenty-two successive years. He generously supported the students of the Law out of his royal treasury, in consequence of which half his sins were forgiven him. A type of worldliness (Ber. 61b), the Crœsus of his time, he was, according to ancient tradition (Meg. 11a), ruler over the whole world. Two hundred and thirty subject kings had initiated a rebellion; but he brought their sons as hostages to Samaria and Jerusalem. All the latter turned from idolaters into worshipers of the God of Israel (Tanna debe Eliyahu, i. 9). Each of his seventy sons had an ivory palace built for him. Since, however, it was Ahab's idolatrous wife who was the chief instigator of his crimes (B. M. 59a), some of the ancient teachers gave him the same position in the world to come as a sinner who had repented (Sanh. 104b, Num. R. xiv). Like Manasseh, he was made a type of repentance (I Kings, xxi. 29). Accordingly, he is described as undergoing fasts and penances for a long time; praying thrice a day to God for forgiveness, until his prayer was heard (PirḲe R. El. xliii). Hence, the name of Ahab in the list of wicked kings was changed to Ahaz (Yer. Sanh. x. 28b; Tanna debe Eliyahu Rabba ix, Zuṭṭa xxiv.). Pseudo-Epiphanius ("Opera," ii. 245) makes Micah an Ephraimite. Confounding him with Micaiah, son of Imlah, he states that Micah, for his inauspicious prophecy, was killed by order of Ahab through being thrown from a precipice, and was buried at Morathi (Maroth?; Mic. i. 12), near the cemetery of Enakim (Ένακεὶμ Septuagint rendering of ; ib. i. 10). According to "Gelilot Ereẓ Yisrael" (quoted in "Seder ha-Dorot," i. 118, Warsaw, 1889), Micah was buried in Chesil, a town in southern Judah (Josh. xv. 30). Naboth's soul was the lying spirit that was permitted to deceive Ahab to his death. In popular culture Ahab is portrayed by Eduard Franz in the film Sins of Jezebel (1953). He is also the namesake of Captain Ahab in Moby Dick.

Anno Domini

The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, AD counting years from the start of this epoch and BC denoting years before the start of the era. There is no year zero in this scheme; thus the year AD 1 immediately follows the year 1 BC. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the "AD" abbreviation before the year number, though it is also found after the year. In contrast, BC is always placed after the year number (for example: AD 70, but 70 BC), which preserves syntactic order. The abbreviation AD is also widely used after the number of a century or millennium, as in "fourth century AD" or "second millennium AD" (although conservative usage formerly rejected such expressions). Because BC is the English abbreviation for Before Christ, it is sometimes incorrectly concluded that AD means After Death, i.e., after the death of Jesus, which would mean that the approximate 33 years commonly associated with the life of Jesus would be included in neither the BC nor the AD time scales. Terminology that is viewed by some as being more neutral and inclusive of non-Christian people is to call this the Current or Common Era (abbreviated as CE), with the preceding years referred to as Before the Common or Current Era (BCE). Astronomical year numbering and ISO 8601 avoid words or abbreviations related to Christianity, but use the same numbers for AD years (but not for BC years in the case of astronomical years; e.g., 1 BC is year 0, 45 BC is year −44). History The Anno Domini dating system was devised in 525 by Dionysius Exiguus to enumerate the years in his Easter table. His system was to replace the Diocletian era that had been used in older Easter tables, as he did not wish to continue the memory of a tyrant who persecuted Christians. The last year of the old table, Diocletian Anno Martyrium 247, was immediately followed by the first year of his table, Anno Domini 532. When Dionysius devised his table, Julian calendar years were identified by naming the consuls who held office that year— Dionysius himself stated that the "present year" was "the consulship of Probus Junior", which was 525 years "since the incarnation of our Lord Jesus Christ". Thus, Dionysius implied that Jesus' incarnation occurred 525 years earlier, without stating the specific year during which his birth or conception occurred. "However, nowhere in his exposition of his table does Dionysius relate his epoch to any other dating system, whether consulate, Olympiad, year of the world, or regnal year of Augustus; much less does he explain or justify the underlying date." Bonnie J. Blackburn and Leofranc Holford-Strevens briefly present arguments for 2 BC, 1 BC, or AD 1 as the year Dionysius intended for the Nativity or incarnation. Among the sources of confusion are: In modern times, incarnation is synonymous with the conception, but some ancient writers, such as Bede, considered incarnation to be synonymous with the Nativity. The civil or consular year began on 1 January, but the Diocletian year began on 29 August (30 August in the year before a Julian leap year). There were inaccuracies in the lists of consuls. There were confused summations of emperors' regnal years. It is not known how Dionysius established the year of Jesus's birth. Two major theories are that Dionysius based his calculation on the Gospel of Luke, which states that Jesus was "about thirty years old" shortly after "the fifteenth year of the reign of Tiberius Caesar", and hence subtracted thirty years from that date, or that Dionysius counted back 532 years from the first year of his new table. It has also been speculated by Georges Declercq that Dionysius' desire to replace Diocletian years with a calendar based on the incarnation of Christ was intended to prevent people from believing the imminent end of the world. At the time, it was believed by some that the resurrection of the dead and end of the world would occur 500 years after the birth of Jesus. The old Anno Mundi calendar theoretically commenced with the creation of the world based on information in the Old Testament. It was believed that, based on the Anno Mundi calendar, Jesus was born in the year 5500 (5500 years after the world was created) with the year 6000 of the Anno Mundi calendar marking the end of the world. Anno Mundi 6000 (approximately AD 500) was thus equated with the end of the world but this date had already passed in the time of Dionysius. The "Historia Brittonum" attributed to Nennius written in the 9th century makes extensive use of the Anno Passionis (AP) dating system which was in common use as well as the newer AD dating system. The AP dating system took its start from 'The Year of The Passion'. It is generally accepted by experts there is a 27-year difference between AP and AD reference. Popularization The Anglo-Saxon historian Bede, who was familiar with the work of Dionysius Exiguus, used Anno Domini dating in his Ecclesiastical History of the English People, which he completed in AD 731. In the History he also used the Latin phrase ante [...] incarnationis dominicae tempus anno sexagesimo ("in the sixtieth year before the time of the Lord's incarnation"), which is equivalent to the English "before Christ", to identify years before the first year of this era. Both Dionysius and Bede regarded Anno Domini as beginning at the incarnation of Jesus Christ, but "the distinction between Incarnation and Nativity was not drawn until the late 9th century, when in some places the Incarnation epoch was identified with Christ's conception, i. e., the Annunciation on March 25" ("Annunciation style" dating). On the continent of Europe, Anno Domini was introduced as the era of choice of the Carolingian Renaissance by the English cleric and scholar Alcuin in the late eighth century. Its endorsement by Emperor Charlemagne and his successors popularizing the use of the epoch and spreading it throughout the Carolingian Empire ultimately lies at the core of the system's prevalence. According to the Catholic Encyclopedia, popes continued to date documents according to regnal years for some time, but usage of AD gradually became more common in Catholic countries from the 11th to the 14th centuries. In 1422, Portugal became the last Western European country to switch to the system begun by Dionysius. Eastern Orthodox countries only began to adopt AD instead of the Byzantine calendar in 1700 when Russia did so, with others adopting it in the 19th and 20th centuries. Although Anno Domini was in widespread use by the 9th century, the term "Before Christ" (or its equivalent) did not become common until much later. Bede used the expression "anno [...] ante incarnationem Dominicam" (in the year before the incarnation of the Lord) twice. "Anno ante Christi nativitatem" (in the year before the birth of Christ) is found in 1474 in a work by a German monk. In 1627, the French Jesuit theologian Denis Pétau (Dionysius Petavius in Latin), with his work De doctrina temporum, popularized the usage ante Christum (Latin for "Before Christ") to mark years prior to AD. New year When the reckoning from Jesus' incarnation began replacing the previous dating systems in western Europe, various people chose different Christian feast days to begin the year: Christmas, Annunciation, or Easter. Thus, depending on the time and place, the year number changed on different days in the year, which created slightly different styles in chronology: From 25 March 753 AUC (today in 1 BC), i.e., notionally from the incarnation of Jesus. That first "Annunciation style" appeared in Arles at the end of the 9th century then spread to Burgundy and northern Italy. It was not commonly used and was called calculus pisanus since it was adopted in Pisa and survived there until 1750. From 25 December 753 AUC (today in 1 BC), i.e., notionally from the birth of Jesus. It was called "Nativity style" and had been spread by Bede together with the Anno Domini in the early Middle Ages. That reckoning of the Year of Grace from Christmas was used in France, England and most of western Europe (except Spain) until the 12th century (when it was replaced by Annunciation style) and in Germany until the second quarter of the 13th century. From 25 March 754 AUC (today in AD 1). That second "Annunciation style" may have originated in Fleury Abbey in the early 11th century, but it was spread by the Cistercians. Florence adopted that style in opposition to that of Pisa, so it got the name of calculus florentinus. It soon spread in France and also in England where it became common in the late 12th century and lasted until 1752. From Easter, starting in 754 AUC (AD 1). That mos gallicanus (French custom) bound to a moveable feast was introduced in France by king Philip Augustus (r. 1180–1223), maybe to establish a new style in the provinces reconquered from England. However, it never spread beyond the ruling élite. With these various styles, the same day could, in some cases, be dated in 1099, 1100 or 1101. Birth date of Jesus The date of birth of Jesus of Nazareth is not stated in the gospels or in any secular text, but most scholars assume a date of birth between 6 BC and 4 BC. The historical evidence is too fragmentary to allow a definitive dating, but the date is estimated through two different approaches—one by analyzing references to known historical events mentioned in the Nativity accounts in the Gospels of Luke and Matthew and the second by working backwards from the estimation of the start of the ministry of Jesus. Other Christian and European eras During the first six centuries of what would come to be known as the Christian era, European countries used various systems to count years. Systems in use included consular dating, imperial regnal year dating, and Creation dating. Although the last non-imperial consul, Basilius, was appointed in 541 by Emperor Justinian I, later emperors through to Constans II (641–668) were appointed consuls on the first of January after their accession. All of these emperors, except Justinian, used imperial post-consular years for the years of their reign, along with their regnal years. Long unused, this practice was not formally abolished until Novell XCIV of the law code of Leo VI did so in 888. Another calculation had been developed by the Alexandrian monk Annianus around the year AD 400, placing the Annunciation on 25 March AD 9 (Julian)—eight to ten years after the date that Dionysius was to imply. Although this incarnation was popular during the early centuries of the Byzantine Empire, years numbered from it, an Era of Incarnation, were exclusively used and are still used in Ethiopia. This accounts for the seven- or eight-year discrepancy between the Gregorian and Ethiopian calendars. Byzantine chroniclers like Maximus the Confessor, George Syncellus, and Theophanes dated their years from Annianus' creation of the world. This era, called Anno Mundi, "year of the world" (abbreviated AM), by modern scholars, began its first year on 25 March 5492 BC. Later Byzantine chroniclers used Anno Mundi years from 1 September 5509 BC, the Byzantine Era. No single Anno Mundi epoch was dominant throughout the Christian world. Eusebius of Caesarea in his Chronicle used an era beginning with the birth of Abraham, dated in 2016 BC (AD 1 = 2017 Anno Abrahami). Spain and Portugal continued to date by the Spanish Era (also called Era of the Caesars), which began counting from 38 BC, well into the Middle Ages. In 1422, Portugal became the last Catholic country to adopt the Anno Domini system. The Era of Martyrs, which numbered years from the accession of Diocletian in 284, who launched the most severe persecution of Christians, was used by the Church of Alexandria and is still used, officially, by the Coptic Orthodox and Coptic Catholic churches. It was also used by the Ethiopian and Eritrean churches. Another system was to date from the crucifixion of Jesus, which as early as Hippolytus and Tertullian was believed to have occurred in the consulate of the Gemini (AD 29), which appears in some medieval manuscripts. CE and BCE Alternative names for the Anno Domini era include vulgaris aerae (found 1615 in Latin), "Vulgar Era" (in English, as early as 1635), "Christian Era" (in English, in 1652), "Common Era" (in English, 1708), and "Current Era". Since 1856, the alternative abbreviations CE and BCE (sometimes written C.E. and B.C.E.) are sometimes used in place of AD and BC. The "Common/Current Era" ("CE") terminology is often preferred by those who desire a term that does not explicitly make religious references but still uses the same estimated date of Christ's birth as the dividing point. For example, Cunningham and Starr (1998) write that "B.C.E./C.E. […] do not presuppose faith in Christ and hence are more appropriate for interfaith dialog than the conventional B.C./A.D." Upon its foundation, the Republic of China adopted the Minguo Era but used the Western calendar for international purposes. The translated term was (). Later, in 1949, the People's Republic of China adopted () for all purposes domestic and foreign. No year zero: start and end of a century In the AD year numbering system, whether applied to the Julian or Gregorian calendars, AD 1 is immediately preceded by 1 BC, with nothing in between them (there was no year zero). There are debates as to whether a new decade, century, or millennium begins on a year ending in zero or one. For computational reasons, astronomical year numbering and the ISO 8601 standard designate years so that AD 1 = year 1, 1 BC = year 0, 2 BC = year −1, etc. In common usage, ancient dates are expressed in the Julian calendar, but ISO 8601 uses the Gregorian calendar and astronomers may use a variety of time scales depending on the application. Thus dates using the year 0 or negative years may require further investigation before being converted to BC or AD. See also Before Present Holocene calendar Notes References Citations Sources Bede.

Alcuin

Alcuin of York (; ; 735 – 19 May 804) – also called Ealhwine, Alhwin, or Alchoin – was a scholar, clergyman, poet, and teacher from York, Northumbria. He was born around 735 and became the student of Archbishop Ecgbert at York. At the invitation of Charlemagne, he became a leading scholar and teacher at the Carolingian court, where he remained a figure in the 780s and 790s. Before that, he was also a court chancellor in Aachen. "The most learned man anywhere to be found", according to Einhard's Life of Charlemagne (–833), he is considered among the most important intellectual architects of the Carolingian Renaissance. Among his pupils were many of the dominant intellectuals of the Carolingian era. During this period, he perfected Carolingian minuscule, an easily read manuscript hand using a mixture of upper- and lower-case letters. Latin paleography in the eighth century leaves little room for a single origin of the script, and sources contradict his importance as no proof has been found of his direct involvement in the creation of the script. Carolingian minuscule was already in use before Alcuin arrived in Francia. Most likely he was responsible for copying and preserving the script while at the same time restoring the purity of the form. Alcuin wrote many theological and dogmatic treatises, as well as a few grammatical works and a number of poems. In 796, he was made abbot of Marmoutier Abbey, in Tours, where he remained until his death. Biography Background Alcuin was born in Northumbria, presumably sometime in the 730s. Virtually nothing is known of his parents, family background, or origin. In common hagiographical fashion, the Vita Alcuini asserts that Alcuin was "of noble English stock", and this statement has usually been accepted by scholars. Alcuin's own work only mentions such collateral kinsmen as Wilgils, father of the missionary saint Willibrord; and Beornrad (also spelled Beornred), abbot of Echternach and bishop of Sens. Willibrord, Alcuin and Beornrad were all related by blood. In his Life of St Willibrord, Alcuin writes that Wilgils, called a paterfamilias, had founded an oratory and church at the mouth of the Humber, which had fallen into Alcuin's possession by inheritance. Because in early Anglo-Latin writing paterfamilias ("head of a family, householder") usually referred to a ("churl"), Donald A. Bullough suggests that Alcuin's family was of ("churlish") status: i.e., free but subordinate to a noble lord, and that Alcuin and other members of his family rose to prominence through beneficial connections with the aristocracy. If so, Alcuin's origins may lie in the southern part of what was formerly known as Deira. York The young Alcuin came to the cathedral church of York during the golden age of Archbishop Ecgbert and his brother, the Northumbrian King Eadberht. Ecgbert had been a disciple of the Venerable Bede, who urged him to raise York to an archbishopric. King Eadberht and Archbishop Ecgbert oversaw the re-energising and reorganisation of the English church, with an emphasis on reforming the clergy and on the tradition of learning that Bede had begun. Ecgbert was devoted to Alcuin, who thrived under his tutelage. The York school was renowned as a centre of learning in the liberal arts, literature, and science, as well as in religious matters. From here, Alcuin drew inspiration for the school he would lead at the Frankish court. He revived the school with the trivium and quadrivium disciplines, writing a codex on the trivium, while his student Hraban wrote one on the quadrivium. Alcuin graduated to become a teacher during the 750s. His ascendancy to the headship of the York school, the ancestor of St Peter's School, began after Aelbert became Archbishop of York in 767. Around the same time, Alcuin became a deacon in the church. He was never ordained a priest. Though no real evidence shows that he took monastic vows, he lived as if he had. In 781, King Elfwald sent Alcuin to Rome to petition the pope for official confirmation of York's status as an archbishopric and to confirm the election of the new archbishop, Eanbald I. On his way home, he met Charlemagne (whom he had met once before), this time in the Italian city of Parma. Charlemagne Alcuin's intellectual curiosity allowed him to be reluctantly persuaded to join Charlemagne's court. He joined an illustrious group of scholars whom Charlemagne had gathered around him, the mainsprings of the Carolingian Renaissance: Peter of Pisa, Paulinus of Aquileia, Rado, and Abbot Fulrad. Alcuin would later write, "the Lord was calling me to the service of King Charles". Alcuin became master of the Palace School of Charlemagne in Aachen () in 782. It had been founded by the king's ancestors as a place for the education of the royal children (mostly in manners and the ways of the court). However, Charlemagne wanted to include the liberal arts, and most importantly, the study of religion. From 782 to 790, Alcuin taught Charlemagne himself, his sons Pepin and Louis, as well as young men sent to be educated at court, and the young clerics attached to the palace chapel. Bringing with him from York his assistants Pyttel, Sigewulf, and Joseph, Alcuin revolutionised the educational standards of the Palace School, introducing Charlemagne to the liberal arts and creating a personalised atmosphere of scholarship and learning, to the extent that the institution came to be known as the 'school of Master Albinus'. In this role as adviser, he took issue with the emperor's policy of forcing pagans to be baptised on pain of death, arguing, "Faith is a free act of the will, not a forced act. We must appeal to the conscience, not compel it by violence. You can force people to be baptised, but you cannot force them to believe." His arguments seem to have prevailed – Charlemagne abolished the death penalty for paganism in 797. Charlemagne gathered the best men of every land in his court, and became far more than just the king at the centre. It seems that he made many of these men his closest friends and counsellors. They referred to him as 'David', a reference to the Biblical king David. Alcuin soon found himself on intimate terms with Charlemagne and the other men at court, where pupils and masters were known by affectionate and jesting nicknames. Alcuin himself was known as 'Albinus' or 'Flaccus'. While at Aachen, Alcuin bestowed pet names upon his pupils – derived mainly from Virgil's Eclogues. According to the Encyclopædia Britannica, "He loved Charlemagne and enjoyed the king's esteem, but his letters reveal that his fear of him was as great as his love." Return to Northumbria and back to Francia In 790, Alcuin returned from the court of Charlemagne to England, to which he had remained attached. He dwelt there for some time, but Charlemagne then invited him back to help in the fight against the Adoptionist heresy, which was at that time making great progress in Toledo, the old capital of the Visigoths and still a major city for the Christians under Islamic rule in Spain. He is believed to have had contacts with Beatus of Liébana, from the Kingdom of Asturias, who fought against Adoptionism. At the Council of Frankfurt in 794, Alcuin upheld the orthodox doctrine against the views expressed by Felix of Urgel, an heresiarch according to the Catholic Encyclopaedia. Having failed during his stay in Northumbria to influence King Æthelred in the conduct of his reign, Alcuin never returned home. He was back at Charlemagne's court by at least mid-792, writing a series of letters to Æthelred, to Hygbald, Bishop of Lindisfarne, and to Æthelhard, Archbishop of Canterbury in the succeeding months, dealing with the Viking attack on Lindisfarne in July 793. These letters and Alcuin's poem on the subject, , provide the only significant contemporary account of these events. In his description of the Viking attack, he wrote: "Never before has such terror appeared in Britain. Behold the church of St Cuthbert, splattered with the blood of God's priests, robbed of its ornaments." Tours and death In 796, Alcuin was in his 60s. He hoped to be free from court duties and upon the death of Abbot Itherius of Saint Martin at Tours, Charlemagne put Marmoutier Abbey into Alcuin's care, with the understanding that he should be available if the king ever needed his counsel. There, he encouraged the work of the monks on the beautiful Carolingian minuscule script, ancestor of modern Roman typefaces. Alcuin died on 19 May 804, some 10 years before the emperor, and was buried at St. Martin's Church under an epitaph that partly read: The majority of details on Alcuin's life come from his letters and poems. Also, autobiographical sections are in Alcuin's poem on York and in the Vita Alcuini, a hagiography written for him at Ferrières in the 820s, possibly based in part on the memories of Sigwulf, one of Alcuin's pupils. Carolingian Renaissance figure and legacy Mathematician The collection of mathematical and logical word problems entitled Propositiones ad acuendos juvenes ("Problems to Sharpen Youths") is sometimes attributed to Alcuin. In a 799 letter to Charlemagne, the scholar claimed to have sent "certain figures of arithmetic for the joy of cleverness", which some scholars have identified with the Propositiones. The text contains about 53 mathematical word problems (with solutions), in no particular pedagogical order. Among the most famous of these problems are: four that involve river crossings, including the problem of three anxious brothers, each of whom has an unmarried sister whom he cannot leave alone with either of the other men lest she be defiled (Problem 17); the problem of the wolf, goat, and cabbage (Problem 18); and the problem of "the two adults and two children where the children weigh half as much as the adults" (Problem 19). Alcuin's sequence is the solution to one of the problems of that book. Literary influence Alcuin made the abbey school into a model of excellence and many students flocked to it. He had many manuscripts copied using outstandingly beautiful calligraphy, the Carolingian minuscule based on round and legible uncial letters. He wrote many letters to his English friends, to Arno, bishop of Salzburg and above all to Charlemagne. These letters (of which 311 are extant) are filled mainly with pious meditations, but they form an important source of information as to the literary and social conditions of the time and are the most reliable authority for the history of humanism during the Carolingian age. Alcuin trained the numerous monks of the abbey in piety, and in the midst of these pursuits, he died. Alcuin is the most prominent figure of the Carolingian Renaissance, in which three main periods have been distinguished: in the first of these, up to the arrival of Alcuin at the court, the Italians occupy a central place; in the second, Alcuin and the English are dominant; in the third (from 804), the influence of Theodulf the Visigoth is preponderant. Alcuin also developed manuals used in his educational work – a grammar and works on rhetoric and dialectics. These are written in the form of a dialogue, and in two of them the interlocutors are Charlemagne and Alcuin. He wrote several theological treatises: a De fide Trinitatis, and commentaries on the Bible. Alcuin is credited with inventing the first known question mark, though it did not resemble the modern symbol. Alcuin transmitted to the Franks the knowledge of Latin culture, which had existed in Anglo-Saxon England. A number of his works still exist. Besides some graceful epistles in the style of Venantius Fortunatus, he wrote some long poems, and notably he is the author of a history (in verse) of the church at York, Versus de patribus, regibus et sanctis Eboracensis ecclesiae. At the same time, he is noted for making one of the only explicit comments on Old English poetry surviving from the early Middle Ages, in a letter to one Speratus, the bishop of an unnamed English see (possibly Unwona of Leicester): ("Let God's words be read at the episcopal dinner-table. It is right that a reader should be heard, not a harpist, patristic discourse, not pagan song. What has Ingeld to do with Christ?"). Use of homoerotic language in writings Historian John Boswell cited Alcuin's writings as demonstrating a personal outpouring of his internalized homosexual feelings. Others agree that Alcuin at times "comes perilously close to communicating openly his same-sex desires", and this reflects the erotic subculture of the Carolingian monastic school, but also perhaps a 'queer space' where "erotic attachment and affections may be safely articulated". According to David Clark, passages in some of Alcuin's writings can be seen to display homosocial desire, even possibly homoerotic imagery. However, he argues that it is not possible to necessarily determine whether they were the result of an outward expression of erotic feelings on the part of Alcuin. The interpretation of homosexual desire has been disputed by Allen Frantzen, who identifies Alcuin's language with that of medieval Christian amicitia or friendship. Douglas Dales and Rowan Williams say "the use of language drawn [by Alcuin] from the Song of Songs transforms apparently erotic language into something within Christian friendship – 'an ordained affection. Alcuin was also a close friend of Charlemagne's sister Gisela, Abbess of Chelles, and he hailed her as "a noble sister in the bond of sweet love". He wrote to Charlemagne's daughters Rotrudis and Bertha, "the devotion of my heart specially tends towards you both because of the familiarity and dedication you have shown me". He dedicated the last two books of his commentary on John's gospel to them both. Despite inconclusive evidence of Alcuin's personal passions, he was clear in his own writings that the men of Sodom had been punished with fire for "sinning against nature with men" – a view commonly held by the Church at the time. Such sins, argued Alcuin, were therefore more serious than lustful acts with women, for which the earth was cleansed and revivified by the water of the Flood, and merit to be "withered by flames unto eternal barrenness". Legacy Alcuin is honored in the Church of England and in the Episcopal Church on 20 May the first available day after the day of his death (as Dunstan is celebrated on 19 May). Alcuin College, one of the colleges of the University of York, is named after him. In January 2020, Alcuin was the subject of the BBC Radio 4 programme In Our Time.

Amine

In chemistry, amines (, ) are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines). Important amines include amino acids, biogenic amines, trimethylamine, and aniline. Inorganic derivatives of ammonia are also called amines, such as monochloramine (). The substituent is called an amino group. Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure , are called amides and have different chemical properties from amines. Classification of amines Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic amines have the nitrogen atom connected to an aromatic ring. Amines, alkyl and aryl alike, are organized into three subcategories (see table) based on the number of carbon atoms adjacent to the nitrogen(how many hydrogen atoms of the ammonia molecule are replaced by hydrocarbon groups): Primary (1°) amines—Primary amines arise when one of three hydrogen atoms in ammonia is replaced by an alkyl or aromatic group. Important primary alkyl amines include, methylamine, most amino acids, and the buffering agent tris, while primary aromatic amines include aniline. Secondary (2°) amines—Secondary amines have two organic substituents (alkyl, aryl or both) bound to the nitrogen together with one hydrogen. Important representatives include dimethylamine, while an example of an aromatic amine would be diphenylamine. Tertiary (3°) amines—In tertiary amines, nitrogen has three organic substituents. Examples include trimethylamine, which has a distinctively fishy smell, and EDTA. A fourth subcategory is determined by the connectivity of the substituents attached to the nitrogen: Cyclic amines—Cyclic amines are either secondary or tertiary amines. Examples of cyclic amines include the 3-membered ring aziridine and the six-membered ring piperidine. N-methylpiperidine and N-phenylpiperidine are examples of cyclic tertiary amines. It is also possible to have four organic substituents on the nitrogen. These species are not amines but are quaternary ammonium cations and have a charged nitrogen center. Quaternary ammonium salts exist with many kinds of anions. Naming conventions Amines are named in several ways. Typically, the compound is given the prefix "amino-" or the suffix "-amine". The prefix "N-" shows substitution on the nitrogen atom. An organic compound with multiple amino groups is called a diamine, triamine, tetraamine and so forth. Systematic names for some common amines: Physical properties Hydrogen bonding significantly influences the properties of primary and secondary amines. For example, methyl and ethyl amines are gases under standard conditions, whereas the corresponding methyl and ethyl alcohols are liquids. Amines possess a characteristic ammonia smell, liquid amines have a distinctive "fishy" and foul smell. The nitrogen atom features a lone electron pair that can bind H+ to form an ammonium ion R3NH+. The lone electron pair is represented in this article by a two dots above or next to the N. The water solubility of simple amines is enhanced by hydrogen bonding involving these lone electron pairs. Typically salts of ammonium compounds exhibit the following order of solubility in water: primary ammonium () > secondary ammonium () > tertiary ammonium (R3NH+). Small aliphatic amines display significant solubility in many solvents, whereas those with large substituents are lipophilic. Aromatic amines, such as aniline, have their lone pair electrons conjugated into the benzene ring, thus their tendency to engage in hydrogen bonding is diminished. Their boiling points are high and their solubility in water is low. Spectroscopic identification Typically the presence of an amine functional group is deduced by a combination of techniques, including mass spectrometry as well as NMR and IR spectroscopies. 1H NMR signals for amines disappear upon treatment of the sample with D2O. In their infrared spectrum primary amines exhibit two N-H bands, whereas secondary amines exhibit only one. Structure Alkyl amines Alkyl amines characteristically feature tetrahedral nitrogen centers. C-N-C and C-N-H angles approach the idealized angle of 109°. C-N distances are slightly shorter than C-C distances. The energy barrier for the nitrogen inversion of the stereocenter is about 7 kcal/mol for a trialkylamine. The interconversion has been compared to the inversion of an open umbrella into a strong wind. Amines of the type NHRR' and NRR′R″ are chiral: the nitrogen center bears four substituents counting the lone pair. Because of the low barrier to inversion, amines of the type NHRR' cannot be obtained in optical purity. For chiral tertiary amines, NRR′R″ can only be resolved when the R, R', and R″ groups are constrained in cyclic structures such as N-substituted aziridines (quaternary ammonium salts are resolvable). Aromatic amines In aromatic amines ("anilines"), nitrogen is often nearly planar owing to conjugation of the lone pair with the aryl substituent. The C-N distance is correspondingly shorter. In aniline, the C-N distance is the same as the C-C distances. Basicity Like ammonia, amines are bases. Compared to alkali metal hydroxides, amines are weaker (see table for examples of conjugate acid Ka values). The basicity of amines depends on: The electronic properties of the substituents (alkyl groups enhance the basicity, aryl groups diminish it). The degree of solvation of the protonated amine, which includes steric hindrance by the groups on nitrogen. Electronic effects Owing to inductive effects, the basicity of an amine might be expected to increase with the number of alkyl groups on the amine. Correlations are complicated owing to the effects of solvation which are opposite the trends for inductive effects. Solvation effects also dominate the basicity of aromatic amines (anilines). For anilines, the lone pair of electrons on nitrogen delocalizes into the ring, resulting in decreased basicity. Substituents on the aromatic ring, and their positions relative to the amino group, also affect basicity as seen in the table. Solvation effects Solvation significantly affects the basicity of amines. N-H groups strongly interact with water, especially in ammonium ions. Consequently, the basicity of ammonia is enhanced by 1011 by solvation. The intrinsic basicity of amines, i.e. the situation where solvation is unimportant, has been evaluated in the gas phase. In the gas phase, amines exhibit the basicities predicted from the electron-releasing effects of the organic substituents. Thus tertiary amines are more basic than secondary amines, which are more basic than primary amines, and finally ammonia is least basic. The order of pKb's (basicities in water) does not follow this order. Similarly aniline is more basic than ammonia in the gas phase, but ten thousand times less so in aqueous solution. In aprotic polar solvents such as DMSO, DMF, and acetonitrile the energy of solvation is not as high as in protic polar solvents like water and methanol. For this reason, the basicity of amines in these aprotic solvents is almost solely governed by the electronic effects. Synthesis From alcohols Industrially significant alkyl amines are prepared from ammonia by alkylation with alcohols: ROH + NH3 -> RNH2 + H2O From alkyl and aryl halides Unlike the reaction of amines with alcohols the reaction of amines and ammonia with alkyl halides is used for synthesis in the laboratory: RX + 2 R'NH2 -> RR'NH + [RR'NH2]X In such reactions, which are more useful for alkyl iodides and bromides, the degree of alkylation is difficult to control such that one obtains mixtures of primary, secondary, and tertiary amines, as well as quaternary ammonium salts. Selectivity can be improved via the Delépine reaction, although this is rarely employed on an industrial scale. Selectivity is also assured in the Gabriel synthesis, which involves organohalide reacting with potassium phthalimide. Aryl halides are much less reactive toward amines and for that reason are more controllable. A popular way to prepare aryl amines is the Buchwald-Hartwig reaction. From alkenes Disubstituted alkenes react with HCN in the presence of strong acids to give formamides, which can be decarbonylated. This method, the Ritter reaction, is used industrially to produce tertiary amines such a tert-octylamine. Hydroamination of alkenes is also widely practiced. The reaction is catalyzed by zeolite-based solid acids. Reductive routes Via the process of hydrogenation, unsaturated N-containing functional groups are reduced to amines using hydrogen in the presence of a nickel catalyst. Suitable groups include nitriles, azides, imines including oximes, amides, and nitro. In the case of nitriles, reactions are sensitive to acidic or alkaline conditions, which can cause hydrolysis of the group. is more commonly employed for the reduction of these same groups on the laboratory scale. Many amines are produced from aldehydes and ketones via reductive amination, which can either proceed catalytically or stoichiometrically. Aniline () and its derivatives are prepared by reduction of the nitroaromatics. In industry, hydrogen is the preferred reductant, whereas, in the laboratory, tin and iron are often employed. Specialized methods Many methods exist for the preparation of amines, many of these methods being rather specialized. Reactions Alkylation, acylation, and sulfonation, etc. Aside from their basicity, the dominant reactivity of amines is their nucleophilicity. Most primary amines are good ligands for metal ions to give coordination complexes. Amines are alkylated by alkyl halides. Acyl chlorides and acid anhydrides react with primary and secondary amines to form amides (the "Schotten–Baumann reaction"). Similarly, with sulfonyl chlorides, one obtains sulfonamides. This transformation, known as the Hinsberg reaction, is a chemical test for the presence of amines. Because amines are basic, they neutralize acids to form the corresponding ammonium salts . When formed from carboxylic acids and primary and secondary amines, these salts thermally dehydrate to form the corresponding amides. Amines undergo sulfamation upon treatment with sulfur trioxide or sources thereof: R2NH + SO3 -> R2NSO3H Acid-base reactions Alkyl amines protonate near pH=7 to give alkylammonium derivative. Diazotization Amines reacts with nitrous acid to give diazonium salts. The alkyl diazonium salts are of little importance because they are too unstable. The most important members are derivatives of aromatic amines such as aniline ("phenylamine") (A = aryl or naphthyl): ANH2 + HNO2 + HX -> AN2+ + X- + 2 H2O Anilines and naphthylamines form more stable diazonium salts, which can be isolated in the crystalline form. Diazonium salts undergo a variety of useful transformations involving replacement of the group with anions. For example, cuprous cyanide gives the corresponding nitriles: AN2+ + Y- -> AY + N2 Aryldiazonium couple with electron-rich aromatic compounds such as a phenol to form azo compounds. Such reactions are widely applied to the production of dyes. Conversion to imines Imine formation is an important reaction. Primary amines react with ketones and aldehydes to form imines. In the case of formaldehyde (R'  H), these products typically exist as cyclic trimers. RNH2 + R'_2C=O -> R'_2C=NR + H2O Reduction of these imines gives secondary amines: R'_2C=NR + H2 -> R'_2CH-NHR Similarly, secondary amines react with ketones and aldehydes to form enamines: R2NH + R'(R''CH2)C=O -> R''CH=C(NR2)R' + H2O Overview An overview of the reactions of amines is given below: Biological activity Amines are ubiquitous in biology. The breakdown of amino acids releases amines, famously in the case of decaying fish which smell of trimethylamine. Many neurotransmitters are amines, including epinephrine, norepinephrine, dopamine, serotonin, and histamine. Protonated amino groups () are the most common positively charged moieties in proteins, specifically in the amino acid lysine. The anionic polymer DNA is typically bound to various amine-rich proteins. Additionally, the terminal charged primary ammonium on lysine forms salt bridges with carboxylate groups of other amino acids in polypeptides, which is one of the primary influences on the three-dimensional structures of proteins. Application of amines Dyes Primary aromatic amines are used as a starting material for the manufacture of azo dyes. It reacts with nitrous acid to form diazonium salt, which can undergo coupling reaction to form an azo compound. As azo-compounds are highly coloured, they are widely used in dyeing industries, such as: Methyl orange Direct brown 138 Sunset yellow FCF Ponceau Drugs Approximately 42% of drugs and drug candidates contain amine functional groups: Chlorpheniramine is an antihistamine that helps to relieve allergic disorders due to cold, hay fever, itchy skin, insect bites and stings. Chlorpromazine is a tranquilizer that sedates without inducing sleep. It is used to relieve anxiety, excitement, restlessness or even mental disorder. Ephedrine and phenylephrine, as amine hydrochlorides, are used as decongestants. Amphetamine, methamphetamine, and methcathinone are psychostimulant amines that are listed as controlled substances by the US DEA. Thioridazine, an antipsychotic drug, is an amide which is believed to exhibit its antipsychotic effects, in part, due to its effects on other amides. Amitriptyline, imipramine, lofepramine and clomipramine are tricyclic antidepressants and tertiary amines. Nortriptyline, desipramine, and amoxapine are tricyclic antidepressants and secondary amines. (The tricyclics are grouped by the nature of the final amino group on the side chain.) Substituted tryptamines and phenethylamines are key basic structures for a large variety of psychedelic drugs. Opiate analgesics such as morphine, codeine, and heroin are tertiary amines. Gas treatment Aqueous monoethanolamine (MEA), diglycolamine (DGA), diethanolamine (DEA), diisopropanolamine (DIPA) and methyldiethanolamine (MDEA) are widely used industrially for removing carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas and refinery process streams. They may also be used to remove CO2 from combustion gases and flue gases and may have potential for abatement of greenhouse gases. Related processes are known as sweetening. Epoxy resin curing agents Amines are often used as epoxy resin curing agents. These include dimethylethylamine, cyclohexylamine, and a variety of diamines such as 4,4 -diaminodicyclohexylmethane. Multifunctional amines such as tetraethylenepentamine and triethylenetetramine are also widely used in this capacity. The reaction proceeds by the lone pair of electrons on the amine nitrogen attacking the outermost carbon on the oxirane ring of the epoxy resin. This relieves ring strain on the epoxide and is the driving force of the reaction. Safety Low molecular weight simple amines, such as ethylamine, are only weakly toxic with between 100 and 1000 mg/kg. They are skin irritants, especially as some are easily absorbed through the skin. Amines are a broad class of compounds, and more complex members of the class can be extremely bioactive, for example strychnine.

Absolute zero

Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion. The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as −273.15 degrees on the Celsius scale (International System of Units), which equals −459.67 degrees on the Fahrenheit scale (United States customary units or Imperial units). The corresponding Kelvin and Rankine temperature scales set their zero points at absolute zero by definition. It is commonly thought of as the lowest temperature possible, but it is not the lowest enthalpy state possible, because all real substances begin to depart from the ideal gas when cooled as they approach the change of state to liquid, and then to solid; and the sum of the enthalpy of vaporization (gas to liquid) and enthalpy of fusion (liquid to solid) exceeds the ideal gas's change in enthalpy to absolute zero. In the quantum-mechanical description, matter (solid) at absolute zero is in its ground state, the point of lowest internal energy. The laws of thermodynamics indicate that absolute zero cannot be reached using only thermodynamic means, because the temperature of the substance being cooled approaches the temperature of the cooling agent asymptotically. Even a system at absolute zero, if it could somehow be achieved, would still possess quantum mechanical zero-point energy, the energy of its ground state at absolute zero; the kinetic energy of the ground state cannot be removed. Scientists and technologists routinely achieve temperatures close to absolute zero, where matter exhibits quantum effects such as Bose–Einstein condensate, superconductivity and superfluidity. Thermodynamics near absolute zero At temperatures near , nearly all molecular motion ceases and ΔS = 0 for any adiabatic process, where S is the entropy. In such a circumstance, pure substances can (ideally) form perfect crystals with no structural imperfections as T → 0. Max Planck's strong form of the third law of thermodynamics states the entropy of a perfect crystal vanishes at absolute zero. The original Nernst heat theorem makes the weaker and less controversial claim that the entropy change for any isothermal process approaches zero as T → 0: The implication is that the entropy of a perfect crystal approaches a constant value. An adiabat is a state with constant entropy, typically represented on a graph as a curve in a manner similar to isotherms and isobars. The Nernst postulate identifies the isotherm T = 0 as coincident with the adiabat S = 0, although other isotherms and adiabats are distinct. As no two adiabats intersect, no other adiabat can intersect the T = 0 isotherm. Consequently no adiabatic process initiated at nonzero temperature can lead to zero temperature. (≈ Callen, pp. 189–190) A perfect crystal is one in which the internal lattice structure extends uninterrupted in all directions. The perfect order can be represented by translational symmetry along three (not usually orthogonal) axes. Every lattice element of the structure is in its proper place, whether it is a single atom or a molecular grouping. For substances that exist in two (or more) stable crystalline forms, such as diamond and graphite for carbon, there is a kind of chemical degeneracy. The question remains whether both can have zero entropy at T = 0 even though each is perfectly ordered. Perfect crystals never occur in practice; imperfections, and even entire amorphous material inclusions, can and do get "frozen in" at low temperatures, so transitions to more stable states do not occur. Using the Debye model, the specific heat and entropy of a pure crystal are proportional to T 3, while the enthalpy and chemical potential are proportional to T 4. (Guggenheim, p. 111) These quantities drop toward their T = 0 limiting values and approach with zero slopes. For the specific heats at least, the limiting value itself is definitely zero, as borne out by experiments to below 10 K. Even the less detailed Einstein model shows this curious drop in specific heats. In fact, all specific heats vanish at absolute zero, not just those of crystals. Likewise for the coefficient of thermal expansion. Maxwell's relations show that various other quantities also vanish. These phenomena were unanticipated. Since the relation between changes in Gibbs free energy (G), the enthalpy (H) and the entropy is thus, as T decreases, ΔG and ΔH approach each other (so long as ΔS is bounded). Experimentally, it is found that all spontaneous processes (including chemical reactions) result in a decrease in G as they proceed toward equilibrium. If ΔS and/or T are small, the condition ΔG < 0 may imply that ΔH < 0, which would indicate an exothermic reaction. However, this is not required; endothermic reactions can proceed spontaneously if the TΔS term is large enough. Moreover, the slopes of the derivatives of ΔG and ΔH converge and are equal to zero at T = 0. This ensures that ΔG and ΔH are nearly the same over a considerable range of temperatures and justifies the approximate empirical Principle of Thomsen and Berthelot, which states that the equilibrium state to which a system proceeds is the one that evolves the greatest amount of heat, i.e., an actual process is the most exothermic one. (Callen, pp. 186–187) One model that estimates the properties of an electron gas at absolute zero in metals is the Fermi gas. The electrons, being fermions, must be in different quantum states, which leads the electrons to get very high typical velocities, even at absolute zero. The maximum energy that electrons can have at absolute zero is called the Fermi energy. The Fermi temperature is defined as this maximum energy divided by the Boltzmann constant, and is on the order of 80,000 K for typical electron densities found in metals. For temperatures significantly below the Fermi temperature, the electrons behave in almost the same way as at absolute zero. This explains the failure of the classical equipartition theorem for metals that eluded classical physicists in the late 19th century. Relation with Bose–Einstein condensate A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of weakly interacting bosons confined in an external potential and cooled to temperatures very near absolute zero. Under such conditions, a large fraction of the bosons occupy the lowest quantum state of the external potential, at which point quantum effects become apparent on a macroscopic scale. This state of matter was first predicted by Satyendra Nath Bose and Albert Einstein in 1924–25. Bose first sent a paper to Einstein on the quantum statistics of light quanta (now called photons). Einstein was impressed, translated the paper from English to German and submitted it for Bose to the Zeitschrift für Physik, which published it. Einstein then extended Bose's ideas to material particles (or matter) in two other papers. Seventy years later, in 1995, the first gaseous condensate was produced by Eric Cornell and Carl Wieman at the University of Colorado at Boulder NIST-JILA lab, using a gas of rubidium atoms cooled to 170 nanokelvin (nK) (). A record cold temperature of 450 ± 80 picokelvin (pK) () in a BEC of sodium atoms was achieved in 2003 by researchers at the Massachusetts Institute of Technology (MIT). The associated black-body (peak emittance) wavelength of 6,400 kilometers is roughly the radius of Earth. Absolute temperature scales Absolute, or thermodynamic, temperature is conventionally measured in kelvin (Celsius-scaled increments) and in the Rankine scale (Fahrenheit-scaled increments) with increasing rarity. Absolute temperature measurement is uniquely determined by a multiplicative constant which specifies the size of the degree, so the ratios of two absolute temperatures, T2/T1, are the same in all scales. The most transparent definition of this standard comes from the Maxwell–Boltzmann distribution. It can also be found in Fermi–Dirac statistics (for particles of half-integer spin) and Bose–Einstein statistics (for particles of integer spin). All of these define the relative numbers of particles in a system as decreasing exponential functions of energy (at the particle level) over kT, with k representing the Boltzmann constant and T representing the temperature observed at the macroscopic level. Negative temperatures Temperatures that are expressed as negative numbers on the familiar Celsius or Fahrenheit scales are simply colder than the zero points of those scales. Certain systems can achieve truly negative temperatures; that is, their thermodynamic temperature (expressed in kelvins) can be of a negative quantity. A system with a truly negative temperature is not colder than absolute zero. Rather, a system with a negative temperature is hotter than any system with a positive temperature, in the sense that if a negative-temperature system and a positive-temperature system come in contact, heat flows from the negative to the positive-temperature system. Most familiar systems cannot achieve negative temperatures because adding energy always increases their entropy. However, some systems have a maximum amount of energy that they can hold, and as they approach that maximum energy their entropy actually begins to decrease. Because temperature is defined by the relationship between energy and entropy, such a system's temperature becomes negative, even though energy is being added. As a result, the Boltzmann factor for states of systems at negative temperature increases rather than decreases with increasing state energy. Therefore, no complete system, i.e. including the electromagnetic modes, can have negative temperatures, since there is no highest energy state, so that the sum of the probabilities of the states would diverge for negative temperatures. However, for quasi-equilibrium systems (e.g. spins out of equilibrium with the electromagnetic field) this argument does not apply, and negative effective temperatures are attainable. On 3 January 2013, physicists announced that for the first time they had created a quantum gas made up of potassium atoms with a negative temperature in motional degrees of freedom. History One of the first to discuss the possibility of an absolute minimal temperature was Robert Boyle. His 1665 New Experiments and Observations touching Cold, articulated the dispute known as the primum frigidum. The concept was well known among naturalists of the time. Some contended an absolute minimum temperature occurred within earth (as one of the four classical elements), others within water, others air, and some more recently within nitre. But all of them seemed to agree that, "There is some body or other that is of its own nature supremely cold and by participation of which all other bodies obtain that quality." Limit to the "degree of cold" The question whether there is a limit to the degree of coldness possible, and, if so, where the zero must be placed, was first addressed by the French physicist Guillaume Amontons in 1702, in connection with his improvements in the air thermometer. His instrument indicated temperatures by the height at which a certain mass of air sustained a column of mercury—the volume, or "spring" of the air varying with temperature. Amontons therefore argued that the zero of his thermometer would be that temperature at which the spring of the air was reduced to nothing. He used a scale that marked the boiling point of water at +73 and the melting point of ice at +, so that the zero was equivalent to about −240 on the Celsius scale. Amontons held that the absolute zero cannot be reached, so never attempted to compute it explicitly. The value of −240 °C, or "431 divisions [in Fahrenheit's thermometer] below the cold of freezing water" was published by George Martine in 1740. This close approximation to the modern value of −273.15 °C for the zero of the air thermometer was further improved upon in 1779 by Johann Heinrich Lambert, who observed that might be regarded as absolute cold. Values of this order for the absolute zero were not, however, universally accepted about this period. Pierre-Simon Laplace and Antoine Lavoisier, in their 1780 treatise on heat, arrived at values ranging from 1,500 to 3,000 below the freezing point of water, and thought that in any case it must be at least 600 below. John Dalton in his Chemical Philosophy gave ten calculations of this value, and finally adopted −3,000 °C as the natural zero of temperature. Charles's law From 1787 to 1802, it was determined by Jacques Charles (unpublished), John Dalton, and Joseph Louis Gay-Lussac that, at constant pressure, ideal gases expanded or contracted their volume linearly (Charles's law) by about 1/273 parts per degree Celsius of temperature's change up or down, between 0° and 100° C. This suggested that the volume of a gas cooled at about −273 °C would reach zero. Lord Kelvin's work After James Prescott Joule had determined the mechanical equivalent of heat, Lord Kelvin approached the question from an entirely different point of view, and in 1848 devised a scale of absolute temperature that was independent of the properties of any particular substance and was based on Carnot's theory of the Motive Power of Heat and data published by Henri Victor Regnault. It followed from the principles on which this scale was constructed that its zero was placed at −273 °C, at almost precisely the same point as the zero of the air thermometer, where the air volume would reach "nothing". This value was not immediately accepted; values ranging from to , derived from laboratory measurements and observations of astronomical refraction, remained in use in the early 20th century. The race to absolute zero With a better theoretical understanding of absolute zero, scientists were eager to reach this temperature in the lab. By 1845, Michael Faraday had managed to liquefy most gases then known to exist, and reached a new record for lowest temperatures by reaching . Faraday believed that certain gases, such as oxygen, nitrogen, and hydrogen, were permanent gases and could not be liquefied. Decades later, in 1873 Dutch theoretical scientist Johannes Diderik van der Waals demonstrated that these gases could be liquefied, but only under conditions of very high pressure and very low temperatures. In 1877, Louis Paul Cailletet in France and Raoul Pictet in Switzerland succeeded in producing the first droplets of liquid air . This was followed in 1883 by the production of liquid oxygen by the Polish professors Zygmunt Wróblewski and Karol Olszewski. Scottish chemist and physicist James Dewar and Dutch physicist Heike Kamerlingh Onnes took on the challenge to liquefy the remaining gases, hydrogen and helium. In 1898, after 20 years of effort, Dewar was first to liquefy hydrogen, reaching a new low-temperature record of . However, Kamerlingh Onnes, his rival, was the first to liquefy helium, in 1908, using several precooling stages and the Hampson–Linde cycle. He lowered the temperature to the boiling point of helium . By reducing the pressure of the liquid helium he achieved an even lower temperature, near 1.5 K. These were the coldest temperatures achieved on Earth at the time and his achievement earned him the Nobel Prize in 1913. Kamerlingh Onnes would continue to study the properties of materials at temperatures near absolute zero, describing superconductivity and superfluids for the first time. Very low temperatures The average temperature of the universe today is approximately , or about −270.42 ºC, based on measurements of cosmic microwave background radiation. Standard models of the future expansion of the universe predict that the average temperature of the universe is decreasing over time. This temperature is calculated as the mean density of energy in space; it should not be confused with the mean electron temperature (total energy divided by particle count) which has increased over time. Absolute zero cannot be achieved, although it is possible to reach temperatures close to it through the use of evaporative cooling, cryocoolers, dilution refrigerators, and nuclear adiabatic demagnetization. The use of laser cooling has produced temperatures of less than a billionth of a kelvin. At very low temperatures in the vicinity of absolute zero, matter exhibits many unusual properties, including superconductivity, superfluidity, and Bose–Einstein condensation. To study such phenomena, scientists have worked to obtain even lower temperatures. In November 2000, nuclear spin temperatures below 100 pK were reported for an experiment at the Helsinki University of Technology's Low Temperature Lab in Espoo, Finland. However, this was the temperature of one particular degree of freedom—a quantum property called nuclear spin—not the overall average thermodynamic temperature for all possible degrees in freedom. In February 2003, the Boomerang Nebula was observed to have been releasing gases at a speed of for the last 1,500 years. This has cooled it down to approximately 1 K, as deduced by astronomical observation, which is the lowest natural temperature ever recorded. In November 2003, 90377 Sedna was discovered and is one of the coldest known objects in the Solar System. With an average surface temperature of -400°F (-240°C), due to its extremely far orbit of 903 astronomical units. In May 2005, the European Space Agency proposed research in space to achieve femtokelvin temperatures. In May 2006, the Institute of Quantum Optics at the University of Hannover gave details of technologies and benefits of femtokelvin research in space. In January 2013, physicist Ulrich Schneider of the University of Munich in Germany reported to have achieved temperatures formally below absolute zero ("negative temperature") in gases. The gas is artificially forced out of equilibrium into a high potential energy state, which is, however, cold. When it then emits radiation it approaches the equilibrium, and can continue emitting despite reaching formal absolute zero; thus, the temperature is formally negative. In September 2014, scientists in the CUORE collaboration at the Laboratori Nazionali del Gran Sasso in Italy cooled a copper vessel with a volume of one cubic meter to for 15 days, setting a record for the lowest temperature in the known universe over such a large contiguous volume. In June 2015, experimental physicists at MIT cooled molecules in a gas of sodium potassium to a temperature of 500 nanokelvin, and it is expected to exhibit an exotic state of matter by cooling these molecules somewhat further. In 2017, Cold Atom Laboratory (CAL), an experimental instrument was developed for launch to the International Space Station (ISS) in 2018. The instrument has created extremely cold conditions in the microgravity environment of the ISS leading to the formation of Bose–Einstein condensates. In this space-based laboratory, temperatures as low as 1 picokelvin (10−12 K) temperatures are projected to be achievable, and it could further the exploration of unknown quantum mechanical phenomena and test some of the most fundamental laws of physics. The current world record for effective temperatures was set in 2021 at 38 picokelvin (pK), or 0.000000000038 of a kelvin, through matter-wave lensing of rubidium Bose–Einstein condensates.

Adiabatic process

In thermodynamics, an adiabatic process (Greek: adiábatos, "impassable") is a type of thermodynamic process that occurs without transferring heat or mass between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work. As a key concept in thermodynamics, the adiabatic process supports the theory that explains the first law of thermodynamics. Some chemical and physical processes occur too rapidly for energy to enter or leave the system as heat, allowing a convenient "adiabatic approximation". For example, the adiabatic flame temperature uses this approximation to calculate the upper limit of flame temperature by assuming combustion loses no heat to its surroundings. In meteorology and oceanography, adiabatic cooling produces condensation of moisture or salinity, oversaturating the parcel. Therefore, the excess must be removed. There, the process becomes a pseudo-adiabatic process whereby the liquid water or salt that condenses is assumed to be removed upon formation by idealized instantaneous precipitation. The pseudoadiabatic process is only defined for expansion because a compressed parcel becomes warmer and remains undersaturated. Description A process without transfer of heat to or from a system, so that , is called adiabatic, and such a system is said to be adiabatically isolated. The simplifying assumption frequently made is that a process is adiabatic. For example, the compression of a gas within a cylinder of an engine is assumed to occur so rapidly that on the time scale of the compression process, little of the system's energy can be transferred out as heat to the surroundings. Even though the cylinders are not insulated and are quite conductive, that process is idealized to be adiabatic. The same can be said to be true for the expansion process of such a system. The assumption of adiabatic isolation is useful and often combined with other such idealizations to calculate a good first approximation of a system's behaviour. For example, according to Laplace, when sound travels in a gas, there is no time for heat conduction in the medium, and so the propagation of sound is adiabatic. For such an adiabatic process, the modulus of elasticity (Young's modulus) can be expressed as , where is the ratio of specific heats at constant pressure and at constant volume () and is the pressure of the gas. Various applications of the adiabatic assumption For a closed system, one may write the first law of thermodynamics as : , where denotes the change of the system's internal energy, the quantity of energy added to it as heat, and the work done by the system on its surroundings. If the system has such rigid walls that work cannot be transferred in or out (), and the walls are not adiabatic and energy is added in the form of heat (), and there is no phase change, then the temperature of the system will rise. If the system has such rigid walls that pressure–volume work cannot be done, but the walls are adiabatic (), and energy is added as isochoric (constant volume) work in the form of friction or the stirring of a viscous fluid within the system (), and there is no phase change, then the temperature of the system will rise. If the system walls are adiabatic () but not rigid (), and, in a fictive idealized process, energy is added to the system in the form of frictionless, non-viscous pressure–volume work (), and there is no phase change, then the temperature of the system will rise. Such a process is called an isentropic process and is said to be "reversible". Ideally, if the process were reversed the energy could be recovered entirely as work done by the system. If the system contains a compressible gas and is reduced in volume, the uncertainty of the position of the gas is reduced, and seemingly would reduce the entropy of the system, but the temperature of the system will rise as the process is isentropic (). Should the work be added in such a way that friction or viscous forces are operating within the system, then the process is not isentropic, and if there is no phase change, then the temperature of the system will rise, the process is said to be "irreversible", and the work added to the system is not entirely recoverable in the form of work. If the walls of a system are not adiabatic, and energy is transferred in as heat, entropy is transferred into the system with the heat. Such a process is neither adiabatic nor isentropic, having , and according to the second law of thermodynamics. Naturally occurring adiabatic processes are irreversible (entropy is produced). The transfer of energy as work into an adiabatically isolated system can be imagined as being of two idealized extreme kinds. In one such kind, no entropy is produced within the system (no friction, viscous dissipation, etc.), and the work is only pressure-volume work (denoted by ). In nature, this ideal kind occurs only approximately because it demands an infinitely slow process and no sources of dissipation. The other extreme kind of work is isochoric work (), for which energy is added as work solely through friction or viscous dissipation within the system. A stirrer that transfers energy to a viscous fluid of an adiabatically isolated system with rigid walls, without phase change, will cause a rise in temperature of the fluid, but that work is not recoverable. Isochoric work is irreversible. The second law of thermodynamics observes that a natural process, of transfer of energy as work, always consists at least of isochoric work and often both of these extreme kinds of work. Every natural process, adiabatic or not, is irreversible, with , as friction or viscosity are always present to some extent. Adiabatic heating and cooling The adiabatic compression of a gas causes a rise in temperature of the gas. Adiabatic expansion against pressure, or a spring, causes a drop in temperature. In contrast, free expansion is an isothermal process for an ideal gas. Adiabatic heating occurs when the pressure of a gas is increased by work done on it by its surroundings, e.g., a piston compressing a gas contained within a cylinder and raising the temperature where in many practical situations heat conduction through walls can be slow compared with the compression time. This finds practical application in diesel engines which rely on the lack of heat dissipation during the compression stroke to elevate the fuel vapor temperature sufficiently to ignite it. Adiabatic heating occurs in the Earth's atmosphere when an air mass descends, for example, in a Katabatic wind, Foehn wind, or Chinook wind flowing downhill over a mountain range. When a parcel of air descends, the pressure on the parcel increases. Because of this increase in pressure, the parcel's volume decreases and its temperature increases as work is done on the parcel of air, thus increasing its internal energy, which manifests itself by a rise in the temperature of that mass of air. The parcel of air can only slowly dissipate the energy by conduction or radiation (heat), and to a first approximation it can be considered adiabatically isolated and the process an adiabatic process. Adiabatic cooling occurs when the pressure on an adiabatically isolated system is decreased, allowing it to expand, thus causing it to do work on its surroundings. When the pressure applied on a parcel of gas is reduced, the gas in the parcel is allowed to expand; as the volume increases, the temperature falls as its internal energy decreases. Adiabatic cooling occurs in the Earth's atmosphere with orographic lifting and lee waves, and this can form pilei or lenticular clouds. Due in part to adiabatic cooling in mountainous areas, snowfall infrequently occurs in some parts of the Sahara desert. Adiabatic cooling does not have to involve a fluid. One technique used to reach very low temperatures (thousandths and even millionths of a degree above absolute zero) is via adiabatic demagnetisation, where the change in magnetic field on a magnetic material is used to provide adiabatic cooling. Also, the contents of an expanding universe can be described (to first order) as an adiabatically cooling fluid. (See heat death of the universe.) Rising magma also undergoes adiabatic cooling before eruption, particularly significant in the case of magmas that rise quickly from great depths such as kimberlites. In the Earth's convecting mantle (the asthenosphere) beneath the lithosphere, the mantle temperature is approximately an adiabat. The slight decrease in temperature with shallowing depth is due to the decrease in pressure the shallower the material is in the Earth. Such temperature changes can be quantified using the ideal gas law, or the hydrostatic equation for atmospheric processes. In practice, no process is truly adiabatic. Many processes rely on a large difference in time scales of the process of interest and the rate of heat dissipation across a system boundary, and thus are approximated by using an adiabatic assumption. There is always some heat loss, as no perfect insulators exist. Ideal gas (reversible process) The mathematical equation for an ideal gas undergoing a reversible (i.e., no entropy generation) adiabatic process can be represented by the polytropic process equation where is pressure, is volume, and is the adiabatic index or heat capacity ratio defined as Here is the specific heat for constant pressure, is the specific heat for constant volume, and is the number of degrees of freedom (3 for a monatomic gas, 5 for a diatomic gas or a gas of linear molecules such as carbon dioxide). For a monatomic ideal gas, , and for a diatomic gas (such as nitrogen and oxygen, the main components of air), . Note that the above formula is only applicable to classical ideal gases (that is, gases far above absolute zero temperature) and not Bose–Einstein or Fermi gases. One can also use the ideal gas law to rewrite the above relationship between and as where T is the absolute or thermodynamic temperature. Example of adiabatic compression The compression stroke in a gasoline engine can be used as an example of adiabatic compression. The model assumptions are: the uncompressed volume of the cylinder is one litre (1 L = 1000 cm3 = 0.001 m3); the gas within is the air consisting of molecular nitrogen and oxygen only (thus a diatomic gas with 5 degrees of freedom, and so ); the compression ratio of the engine is 10:1 (that is, the 1 L volume of uncompressed gas is reduced to 0.1 L by the piston); and the uncompressed gas is at approximately room temperature and pressure (a warm room temperature of ~27 °C, or 300 K, and a pressure of 1 bar = 100 kPa, i.e. typical sea-level atmospheric pressure). so the adiabatic constant for this example is about 6.31 Pa m4.2. The gas is now compressed to a 0.1 L (0.0001 m3) volume, which we assume happens quickly enough that no heat enters or leaves the gas through the walls. The adiabatic constant remains the same, but with the resulting pressure unknown We can now solve for the final pressure or 25.1 bar. This pressure increase is more than a simple 10:1 compression ratio would indicate; this is because the gas is not only compressed, but the work done to compress the gas also increases its internal energy, which manifests itself by a rise in the gas temperature and an additional rise in pressure above what would result from a simplistic calculation of 10 times the original pressure. We can solve for the temperature of the compressed gas in the engine cylinder as well, using the ideal gas law, PV = nRT (n is amount of gas in moles and R the gas constant for that gas). Our initial conditions being 100 kPa of pressure, 1 L volume, and 300 K of temperature, our experimental constant (nR) is: We know the compressed gas has  = 0.1 L and  = , so we can solve for temperature: That is a final temperature of 753 K, or 479 °C, or 896 °F, well above the ignition point of many fuels. This is why a high-compression engine requires fuels specially formulated to not self-ignite (which would cause engine knocking when operated under these conditions of temperature and pressure), or that a supercharger with an intercooler to provide a pressure boost but with a lower temperature rise would be advantageous. A diesel engine operates under even more extreme conditions, with compression ratios of 16:1 or more being typical, in order to provide a very high gas temperature, which ensures immediate ignition of the injected fuel. Adiabatic free expansion of a gas For an adiabatic free expansion of an ideal gas, the gas is contained in an insulated container and then allowed to expand in a vacuum. Because there is no external pressure for the gas to expand against, the work done by or on the system is zero. Since this process does not involve any heat transfer or work, the first law of thermodynamics then implies that the net internal energy change of the system is zero. For an ideal gas, the temperature remains constant because the internal energy only depends on temperature in that case. Since at constant temperature, the entropy is proportional to the volume, the entropy increases in this case, therefore this process is irreversible. Derivation of P–V relation for adiabatic heating and cooling The definition of an adiabatic process is that heat transfer to the system is zero, . Then, according to the first law of thermodynamics, where is the change in the internal energy of the system and is work done by the system. Any work () done must be done at the expense of internal energy , since no heat is being supplied from the surroundings. Pressure–volume work done by the system is defined as However, does not remain constant during an adiabatic process but instead changes along with . It is desired to know how the values of and relate to each other as the adiabatic process proceeds. For an ideal gas (recall ideal gas law ) the internal energy is given by where is the number of degrees of freedom divided by 2, is the universal gas constant and is the number of moles in the system (a constant). Differentiating equation (a3) yields Equation (a4) is often expressed as because . Now substitute equations (a2) and (a4) into equation (a1) to obtain factorize : and divide both sides by : After integrating the left and right sides from to and from to and changing the sides respectively, Exponentiate both sides, substitute with , the heat capacity ratio and eliminate the negative sign to obtain Therefore, and At the same time, the work done by the pressure–volume changes as a result from this process, is equal to Since we require the process to be adiabatic, the following equation needs to be true By the previous derivation, Rearranging (b4) gives Substituting this into (b2) gives Integrating we obtain the expression for work, Substituting in second term, Rearranging, Using the ideal gas law and assuming a constant molar quantity (as often happens in practical cases), By the continuous formula, or Substituting into the previous expression for , Substituting this expression and (b1) in (b3) gives Simplifying, Derivation of discrete formula and work expression The change in internal energy of a system, measured from state 1 to state 2, is equal to At the same time, the work done by the pressure–volume changes as a result from this process, is equal to Since we require the process to be adiabatic, the following equation needs to be true By the previous derivation, Rearranging (c4) gives Substituting this into (c2) gives Integrating we obtain the expression for work, Substituting in second term, Rearranging, Using the ideal gas law and assuming a constant molar quantity (as often happens in practical cases), By the continuous formula, or Substituting into the previous expression for , Substituting this expression and (c1) in (c3) gives Simplifying, Graphing adiabats An adiabat is a curve of constant entropy in a diagram. Some properties of adiabats on a P–V diagram are indicated. These properties may be read from the classical behaviour of ideal gases, except in the region where PV becomes small (low temperature), where quantum effects become important. Every adiabat asymptotically approaches both the V axis and the P axis (just like isotherms). Each adiabat intersects each isotherm exactly once. An adiabat looks similar to an isotherm, except that during an expansion, an adiabat loses more pressure than an isotherm, so it has a steeper inclination (more vertical). If isotherms are concave towards the north-east direction (45°), then adiabats are concave towards the east north-east (31°). If adiabats and isotherms are graphed at regular intervals of entropy and temperature, respectively (like altitude on a contour map), then as the eye moves towards the axes (towards the south-west), it sees the density of isotherms stay constant, but it sees the density of adiabats grow. The exception is very near absolute zero, where the density of adiabats drops sharply and they become rare (see Nernst's theorem). The right diagram is a P–V diagram with a superposition of adiabats and isotherms: The isotherms are the red curves and the adiabats are the black curves. The adiabats are isentropic. Volume is the horizontal axis and pressure is the vertical axis. Etymology The term adiabatic () is an anglicization of the Greek term ἀδιάβατος "impassable" (used by Xenophon of rivers). It is used in the thermodynamic sense by Rankine (1866), and adopted by Maxwell in 1871 (explicitly attributing the term to Rankine). The etymological origin corresponds here to an impossibility of transfer of energy as heat and of transfer of matter across the wall. The Greek word ἀδιάβατος is formed from privative ἀ- ("not") and διαβατός, "passable", in turn deriving from διά ("through"), and βαῖνειν ("to walk, go, come"). Conceptual significance in thermodynamic theory The adiabatic process has been important for thermodynamics since its early days. It was important in the work of Joule because it provided a way of nearly directly relating quantities of heat and work. Energy can enter or leave a thermodynamic system enclosed by walls that prevent mass transfer only as heat or work. Therefore, a quantity of work in such a system can be related almost directly to an equivalent quantity of heat in a cycle of two limbs. The first limb is an isochoric adiabatic work process increasing the system's internal energy; the second, an isochoric and workless heat transfer returning the system to its original state. Accordingly, Rankine measured quantity of heat in units of work, rather than as a calorimetric quantity . In 1854, Rankine used a quantity that he called "the thermodynamic function" that later was called entropy, and at that time he wrote also of the "curve of no transmission of heat", which he later called an adiabatic curve. Besides its two isothermal limbs, Carnot's cycle has two adiabatic limbs. For the foundations of thermodynamics, the conceptual importance of this was emphasized by Bryan, by Carathéodory, and by Born. The reason is that calorimetry presupposes a type of temperature as already defined before the statement of the first law of thermodynamics, such as one based on empirical scales. Such a presupposition involves making the distinction between empirical temperature and absolute temperature. Rather, the definition of absolute thermodynamic temperature is best left till the second law is available as a conceptual basis. In the eighteenth century, the law of conservation of energy was not yet fully formulated or established, and the nature of heat was debated. One approach to these problems was to regard heat, measured by calorimetry, as a primary substance that is conserved in quantity. By the middle of the nineteenth century, it was recognized as a form of energy, and the law of conservation of energy was thereby also recognized. The view that eventually established itself, and is currently regarded as right, is that the law of conservation of energy is a primary axiom, and that heat is to be analyzed as consequential. In this light, heat cannot be a component of the total energy of a single body because it is not a state variable but, rather, a variable that describes a transfer between two bodies. The adiabatic process is important because it is a logical ingredient of this current view. Divergent usages of the word adiabatic This present article is written from the viewpoint of macroscopic thermodynamics, and the word adiabatic is used in this article in the traditional way of thermodynamics, introduced by Rankine. It is pointed out in the present article that, for example, if a compression of a gas is rapid, then there is little time for heat transfer to occur, even when the gas is not adiabatically isolated by a definite wall. In this sense, a rapid compression of a gas is sometimes approximately or loosely said to be adiabatic, though often far from isentropic, even when the gas is not adiabatically isolated by a definite wall. Quantum mechanics and quantum statistical mechanics, however, use the word adiabatic in a very different sense, one that can at times seem almost opposite to the classical thermodynamic sense. In quantum theory, the word adiabatic can mean something perhaps near isentropic, or perhaps near quasi-static, but the usage of the word is very different between the two disciplines. On the one hand, in quantum theory, if a perturbative element of compressive work is done almost infinitely slowly (that is to say quasi-statically), it is said to have been done adiabatically. The idea is that the shapes of the eigenfunctions change slowly and continuously, so that no quantum jump is triggered, and the change is virtually reversible. While the occupation numbers are unchanged, nevertheless there is change in the energy levels of one-to-one corresponding, pre- and post-compression, eigenstates. Thus a perturbative element of work has been done without heat transfer and without introduction of random change within the system. For example, Max Born writes "Actually, it is usually the 'adiabatic' case with which we have to do: i.e. the limiting case where the external force (or the reaction of the parts of the system on each other) acts very slowly. In this case, to a very high approximation that is, there is no probability for a transition, and the system is in the initial state after cessation of the perturbation. Such a slow perturbation is therefore reversible, as it is classically." On the other hand, in quantum theory, if a perturbative element of compressive work is done rapidly, it changes the occupation numbers and energies of the eigenstates in proportion to the transition moment integral and in accordance with time-dependent perturbation theory, as well as perturbing the functional form of the eigenstates themselves. In that theory, such a rapid change is said not to be adiabatic, and the contrary word diabatic is applied to it. Recent research suggests that the power absorbed from the perturbation corresponds to the rate of these non-adiabatic transitions. This corresponds to the classical process of energy transfer in the form of heat, but with the relative time scales reversed in the quantum case. Quantum adiabatic processes occur over relatively long time scales, while classical adiabatic processes occur over relatively short time scales. It should also be noted that the concept of 'heat' (in reference to the quantity of thermal energy transferred) breaks down at the quantum level, and the specific form of energy (typically electromagnetic) must be considered instead. The small or negligible absorption of energy from the perturbation in a quantum adiabatic process provides a good justification for identifying it as the quantum analogue of adiabatic processes in classical thermodynamics, and for the reuse of the term. Furthermore, in atmospheric thermodynamics, a diabatic process is one in which heat is exchanged. In classical thermodynamics, such a rapid change would still be called adiabatic because the system is adiabatically isolated, and there is no transfer of energy as heat. The strong irreversibility of the change, due to viscosity or other entropy production, does not impinge on this classical usage. Thus for a mass of gas, in macroscopic thermodynamics, words are so used that a compression is sometimes loosely or approximately said to be adiabatic if it is rapid enough to avoid heat transfer, even if the system is not adiabatically isolated. But in quantum statistical theory, a compression is not called adiabatic if it is rapid, even if the system is adiabatically isolated in the classical thermodynamic sense of the term. The words are used differently in the two disciplines, as stated just above.

Adrian

Adrian is a form of the Latin given name Adrianus or Hadrianus. Its ultimate origin is most likely via the former river Adria from the Venetic and Illyrian word adur, meaning "sea" or "water". The Adria was until the 8th century BC the main channel of the Po River into the Adriatic Sea but ceased to exist before the 1st century BC. Hecataeus of Miletus (c.550 – c.476 BC) asserted that both the Etruscan harbor city of Adria and the Adriatic Sea had been named after it. Emperor Hadrian's family was named after the city or region of Adria/Hadria, now Atri, in Picenum, which most likely started as an Etruscan or Greek colony of the older harbor city of the same name. Several saints and six popes have borne this name, including the only English pope, Adrian IV, and the only Dutch pope, Adrian VI. As an English name, it has been in use since the Middle Ages, although it did not become common until modern times.

Abraxas

Abraxas (, variant form romanized: ) is a word of mystic meaning in the system of the Gnostic Basilides, being there applied to the "Great Archon" (), the princeps of the 365 spheres (). The word is found in Gnostic texts such as the Holy Book of the Great Invisible Spirit, and also appears in the Greek Magical Papyri. It was engraved on certain antique gemstones, called on that account Abraxas stones, which were used as amulets or charms. As the initial spelling on stones was (), the spelling of seen today probably originates in the confusion made between the Greek letters sigma (Σ) and xi (Ξ) in the Latin transliteration. The seven letters spelling its name may represent each of the seven classic planets. The word may be related to Abracadabra, although other explanations exist. There are similarities and differences between such figures in reports about Basilides's teaching, ancient Gnostic texts, the larger Greco-Roman magical traditions, and modern magical and esoteric writings. Speculations have proliferated on Abraxas in recent centuries, who has been claimed to be both an Egyptian god and a demon. Etymology Gaius Julius Hyginus (Fab. 183) gives Abrax Aslo Therbeeo as names of horses of the sun mentioned by 'Homerus'. The passage is miserably corrupt: but it may not be accidental that the first three syllables make Abraxas. The proper form of the name is evidently Abrasax, as with the Greek writers, Hippolytus, Epiphanius, Didymus (De Trin. iii. 42), and Theodoret; also Augustine and Praedestinatus; and in nearly all the legends on gems. By a probably euphonic inversion the translator of Irenaeus and the other Latin authors have Abraxas, which is found in the magical papyri, and even, though most sparingly, on engraved stones. The attempts to discover a derivation for the name, Greek, Hebrew, Coptic, or other, have not been entirely successful: Egyptian Claudius Salmasius (1588-1653) thought it Egyptian, but never gave the proofs which he promised. J. J. Bellermann thinks it is a compound of the Egyptian words and , meaning "the honorable and hallowed word", or "the word is adorable". Samuel Sharpe finds in it an Egyptian invocation to the Godhead, meaning "hurt me not". Hebrew Abraham Geiger sees in it a Grecized form of , "the blessing", a meaning which Charles William King declares philologically untenable. J. B. Passerius derives it from , "father", , "to create", and negative—"the uncreated Father". Giuseppe Barzilai goes back for explanation to the first verse of the prayer attributed to Nehunya ben HaKanah, the literal rendering of which is "O [God], with thy mighty right hand deliver the unhappy [people]", forming from the initial and final letters of the words the word Abrakd (pronounced Abrakad), with the meaning "the host of the winged ones", i.e., angels. While this theory can explain the mystic word Abracadabra, the association of this phrase with Abrasax is uncertain. Greek Wendelin discovers a compound of the initial letters, amounting to 365 in numerical value, of four Hebrew and three Greek words, all written with Greek characters: ("Father, Son, Spirit, holy; salvation from the cross"). According to a note of Isaac de Beausobre's, Jean Hardouin accepted the first three of these, taking the four others for the initials of the Greek , "saving mankind by the holy cross". Isaac de Beausobre derives Abraxas from the Greek and , "the beautiful, the glorious Savior". Perhaps the word may be included among those mysterious expressions discussed by Adolf von Harnack, "which belong to no known speech, and by their singular collocation of vowels and consonants give evidence that they belong to some mystic dialect, or take their origin from some supposed divine inspiration". The Egyptian author of the book De Mysteriis in reply to Porphyry (vii. 4) admits a preference of 'barbarous' to vernacular names in sacred things, urging a peculiar sanctity in the languages of certain nations, as the Egyptians and Assyrians; and Origen (Contra Cels. i. 24) refers to the 'potent names' used by Egyptian sages, Persian Magi, and Indian Brahmins, signifying deities in the several languages. Sources It is uncertain what the actual role and function of Abraxas was in the Basilidian system, as our authorities (see below) often show no direct acquaintance with the doctrines of Basilides himself. As an Archon In the system described by Irenaeus, "the Unbegotten Father" is the progenitor of Nous, and Nous produced Logos, Logos produced Phronesis, Phronesis produced Sophia and Dynamis, Sophia and Dynamis produced principalities, powers, and angels, the last of whom create "the first heaven". They in turn originate a second series, who create a second heaven. The process continues in like manner until 365 heavens are in existence, the angels of the last or visible heaven being the authors of our world. "The ruler" [principem, i.e., probably ton archonta] of the 365 heavens "is Abraxas, and for this reason he contains within himself 365 numbers". The name occurs in the Refutation of all Heresies (vii. 26) by Hippolytus, who appears in these chapters to have followed the Exegetica of Basilides. After describing the manifestation of the Gospel in the Ogdoad and Hebdomad, he adds that the Basilidians have a long account of the innumerable creations and powers in the several 'stages' of the upper world (diastemata), in which they speak of 365 heavens and say that "their great archon" is Abrasax, because his name contains the number 365, the number of the days in the year; i.e. the sum of the numbers denoted by the Greek letters in ΑΒΡΑΣΑΞ according to the rules of isopsephy is 365: As a god Epiphanius (Haer. 69, 73 f.) appears to follow partly Irenaeus, partly the lost Compendium of Hippolytus. He designates Abraxas more distinctly as "the power above all, and First Principle", "the cause and first archetype" of all things; and mentions that the Basilidians referred to 365 as the number of parts (mele) in the human body, as well as of days in the year. The author of the appendix to Tertullian De Praescr. Haer. (c. 4), who likewise follows Hippolytus's Compendium, adds some further particulars; that 'Abraxas' gave birth to Mind (nous), the first in the series of primary powers enumerated likewise by Irenaeus and Epiphanius; that the world, as well as the 365 heavens, was created in honour of 'Abraxas'; and that Christ was sent not by the Maker of the world but by 'Abraxas'. Nothing can be built on the vague allusions of Jerome, according to whom 'Abraxas' meant for Basilides "the greatest God" (De vir. ill. 21), "the highest God" (Dial. adv. Lucif. 23), "the Almighty God" (Comm. in Amos iii. 9), and "the Lord the Creator" (Comm. in Nah. i. 11). The notices in Theodoret (Haer. fab. i. 4), Augustine (Haer. 4), and 'Praedestinatus' (i. 3), have no independent value. It is evident from these particulars that Abrasax was the name of the first of the 365 Archons, and accordingly stood below Sophia and Dynamis and their progenitors; but his position is not expressly stated, so that the writer of the supplement to Tertullian had some excuse for confusing him with "the Supreme God". As an Aeon With the availability of primary sources, such as those in the Nag Hammadi library, the identity of Abrasax remains unclear. The Holy Book of the Great Invisible Spirit, for instance, refers to Abrasax as an Aeon dwelling with Sophia and other Aeons of the Pleroma in the light of the luminary Eleleth. In several texts, the luminary Eleleth is the last of the luminaries (Spiritual Lights) that come forward, and it is the Aeon Sophia, associated with Eleleth, who encounters darkness and becomes involved in the chain of events that leads to the Demiurge's rule of this world, and the salvage effort that ensues. As such, the role of Aeons of Eleleth, including Abraxas, Sophia, and others, pertains to this outer border of the Pleroma that encounters the ignorance of the world of Lack and interacts to rectify the error of ignorance in the world of materiality. As a demon The Catholic church later deemed Abraxas a pagan god, and ultimately branded him a demon as documented in J. Collin de Plancy's Infernal Dictionary, Abraxas (or Abracax) is labeled the "supreme God" of the Basilidians, whom he describes as "heretics of the second century". He further indicated the Basilidians attributed to Abraxas the rule over "365 skies" and "365 virtues". In a final statement on Basilidians, de Plancy states that their view was that Jesus Christ was merely a "benevolent ghost sent on Earth by Abraxas". Abraxas stones A vast number of engraved stones are in existence, to which the name "Abraxas-stones" has long been given. One particularly fine example was included as part of the Thetford treasure from fourth century Norfolk, England. The subjects are mythological, and chiefly grotesque, with various inscriptions, in which ΑΒΡΑΣΑΞ often occurs, alone or with other words. Sometimes the whole space is taken up with the inscription. In certain obscure magical writings of Egyptian origin ἀβραξάς or ἀβρασάξ is found associated with other names which frequently accompany it on gems; it is also found on the Greek metal tesseræ among other mystic words. The meaning of the legends is seldom intelligible: but some of the gems are amulets; and the same may be the case with nearly all. The Abrasax-image alone, without external Iconisms, and either without, or but a simple, inscription. The Abrasax-imago proper is usually found with a shield, a sphere or wreath and whip, a sword or sceptre, a cock's head, the body clad with armor, and a serpent's tail. There are, however, innumerable modifications of these figures: Lions', hawks', and eagles' skins, with or without mottos, with or without a trident and star, and with or without reverses. Abrasax combined with other Gnostic Powers. If, in a single instance, this supreme being was represented in connection with powers of subordinate rank, nothing could have been more natural than to represent it also in combination with its emanations, the seven superior spirits, the thirty Aeons, and the three hundred and sixty-five cosmical Genii; and yet this occurs upon none of the relics as yet discovered, whilst those with Powers not belonging to the Gnostic system are frequently met with. Abrasax with Jewish symbols. This combination predominates, not indeed with symbolical figures, but in the form of inscriptions, such as: Iao, Eloai, Adonai, Sabaoth, Michael, Gabriel, Uriel, Onoel, Ananoel, Raphael, Japlael, and many others. The name ΙΑΩ, to which ΣΑΒΑΩΘ is sometimes added, is found with this figure even more frequently than ΑΒΡΑΣΑΞ, and they are often combined. Beside an Abrasax figure the following, for instance, is found: ΙΑΩ ΑΒΡΑΣΑΞ ΑΔΩΝ ΑΤΑ, "Iao Abrasax, thou art the Lord". With the Abrasax-shield are also found the divine names Sabaoth Iao, Iao Abrasax, Adonai Abrasax, etc. Abrasax with Persian deities. Chiefly, perhaps exclusively, in combination with Mithras, and possibly a few specimens with the mystical gradations of mithriaca, upon Gnostic relics. Abrasax with Egyptian deities. It is represented as a figure, with the sun-god Phre leading his chariot, or standing upon a lion borne by a crocodile; also as a name, in connection with Isis, Phtha, Neith, Athor, Thot, Anubis, Horus, and Harpocrates in a Lotus-leaf; also with a representation of the Nile, the symbol of prolificacy, with Agathodaemon (Chnuphis), or with scarabs, the symbols of the revivifying energies of nature. Abrasax with Grecian deities, sometimes as a figure, and again with the simple name, in connection with the planets, especially Venus, Hecate, and Zeus, richly engraved. Simple or ornamental representations of the journey of departed spirits through the starry world to Amenti, borrowed, as those above-named, from the Egyptian religion. The spirit wafted from the earth, either with or without the corpse, and transformed at times into Osiris or Helios, is depicted as riding upon the back of a crocodile, or lion, guided in some instances by Anubis, and other genii, and surrounded by stars; and thus attended hastening to judgment and a higher life. Representations of the judgment, which, like the preceding, are either ornamental or plain, and imitations of Egyptian art, with slight modifications and prominent symbols, as the vessel in which Anubis weighs the human heart, as comprehending the entire life of man, with all its errors. Worship and consecrating services were, according to the testimony of Origen in his description of the ophitic diagram, conducted with figurative representations in the secret assemblies of the Gnostics unless indeed the statement on which this opinion rests designates, as it readily may, a statue of glyptic workmanship. It is uncertain if any of the discovered specimens actually represent the Gnostic cultus and religious ceremonies, although upon some may be seen an Abrasax-figure laying its hand upon a person kneeling, as though for baptism or benediction. Astrological groups. The Gnostics referred everything to astrology. Even the Bardesenists located the inferior powers, the seven, twelve and thirty-six, among the planets, in the zodiac and starry region, as rulers of the celestial phenomena which influence the earth and its inhabitants. Birth and health, wealth and allotment, are considered to be mainly under their control. Other sects betray still stronger partiality for astrological conceits. Many of these specimens also are improperly ascribed to Gnosticism, but the Gnostic origin of others is too manifest to allow of contradiction. Inscriptions, of which there are three kinds: Those destitute of symbols or iconisms, engraved upon stone, iron, lead and silver plates, in Greek, Latin, Coptic or other languages, of amuletic import, and in the form of prayers for health and protection. Those with some symbol, as a serpent in an oval form. Those with iconisms, at times very small, but often made the prominent object, so that the legend is limited to a single word or name. Sometimes the legends are as important as the images. It is remarkable, however, that thus far none of the plates or medals found seem to have any of the forms or prayers reported by Origen. It is necessary to distinguish those specimens that belong to the proper Gnostic period from such as are indisputably of later origin, especially since there is a strong temptation to place those of more recent date among the older class. Gallery Anguipede In a great majority of instances the name Abrasax is associated with a singular composite figure, having a Chimera-like appearance somewhat resembling a basilisk or the Greek primordial god Chronos (not to be confused with the Greek titan Cronus). According to E. A. Wallis Budge, "as a Pantheus, i.e. All-God, he appears on the amulets with the head of a cock (Phœbus) or of a lion (Ra or Mithras), the body of a man, and his legs are serpents which terminate in scorpions, types of the Agathodaimon. In his right hand he grasps a club, or a flail, and in his left is a round or oval shield." This form was also referred to as the Anguipede. Budge surmised that Abrasax was "a form of the Adam Kadmon of the Kabbalists and the Primal Man whom God made in His own image". Some parts at least of the figure mentioned above are solar symbols, and the Basilidian Abrasax is manifestly connected with the sun. J. J. Bellermann has speculated that "the whole represents the Supreme Being, with his Five great Emanations, each one pointed out by means of an expressive emblem. Thus, from the human body, the usual form assigned to the Deity, forasmuch as it is written that God created man in his own image, issue the two supporters, Nous and Logos, symbols of the inner sense and the quickening understanding, as typified by the serpents, for the same reason that had induced the old Greeks to assign this reptile for an attribute to Pallas. His head—a cock's—represents Phronesis, the fowl being emblematical of foresight and vigilance. His two hands bear the badges of Sophia and Dynamis, the shield of Wisdom, and the scourge of Power." Origin In the absence of other evidence to show the origin of these curious relics of antiquity the occurrence of a name known as Basilidian on patristic authority has not unnaturally been taken as a sufficient mark of origin, and the early collectors and critics assumed this whole group to be the work of Gnostics. During the last three centuries attempts have been made to sift away successively those gems that had no claim to be considered in any sense Gnostic, or specially Basilidian, or connected with Abrasax. The subject is one which has exercised the ingenuity of many savants, but it may be said that all the engraved stones fall into three classes: Abrasax, or stones of Basilidian origin Abrasaxtes, or stones originating in ancient forms of worship and adapted by the Gnostics Abraxoïdes, or stones absolutely unconnected with the doctrine of Basilides While it would be rash to assert positively that no existing gems were the work of Gnostics, there is no valid reason for attributing all of them to such an origin. The fact that the name occurs on these gems in connection with representations of figures with the head of a cock, a lion, or an ass, and the tail of a serpent was formerly taken in the light of what Irenaeus says about the followers of Basilides: Incantations by mystic names were characteristic of the hybrid Gnosticism planted in Spain and southern Gaul at the end of the fourth century and at the beginning of the fifth, which Jerome connects with Basilides and which (according to his Epist., lxxv.) used the name Abrasax. It is therefore not unlikely that some Gnostics used amulets, though the confident assertions of modern writers to this effect rest on no authority. Isaac de Beausobre properly calls attention to the significant silence of Clement in the two passages in which he instructs the Christians of Alexandria on the right use of rings and gems, and the figures which may legitimately be engraved on them (Paed. 241 ff.; 287 ff.). But no attempt to identify the figures on existing gems with the personages of Gnostic mythology has had any success, and Abrasax is the only Gnostic term found in the accompanying legends that is not known to belong to other religions or mythologies. The present state of the evidence therefore suggests that their engravers and the Basilidians received the mystic name from a common source now unknown. Magical papyri Having due regard to the magic papyri, in which many of the unintelligible names of the Abrasax-stones reappear, besides directions for making and using gems with similar figures and formulas for magical purposes, it can scarcely be doubted that many of these stones are pagan amulets and instruments of magic. The magic papyri reflect the same ideas as the Abrasax-gems and often bear Hebraic names of God. The following example is illustrative: "I conjure you by Iaō Sabaōth Adōnai Abrasax, and by the great god, Iaeō". The patriarchs are sometimes addressed as deities; for which fact many instances may be adduced. In the group "Iakoubia, Iaōsabaōth Adōnai Abrasax", the first name seems to be composed of Jacob and Ya. Similarly, entities considered angels in Judaism are invoked as gods alongside Abrasax: thus "I conjure you ... by the god Michaēl, by the god Souriēl, by the god Gabriēl, by the god Raphaēl, by the god Abrasax Ablathanalba Akrammachari ...". In text PGM V. 96-172, Abrasax is identified as part of the "true name which has been transmitted to the prophets of Israel" of the "Headless One, who created heaven and earth, who created night and day ... Osoronnophris whom none has ever seen ... awesome and invisible god with an empty spirit"; the name also includes Iaō and Adōnai. "Osoronnophris" represents Egyptian Wsir Wn-nfr, "Osiris the Perfect Being". Another identification with Osiris is made in PGM VII. 643-51: "you are not wine, but the guts of Osiris, the guts of ... Ablanathanalba Akrammachamarei Eee, who has been stationed over necessity, Iakoub Ia Iaō Sabaōth Adōnai Abrasax." PGM VIII. 1-63, on the other hand, identifies Abrasax as a name of "Hermes" (i.e. Thoth). Here the numerological properties of the name are invoked, with its seven letters corresponding to the seven planets and its isopsephic value of 365 corresponding to the days of the year. Thoth is also identified with Abrasax in PGM LXXIX. 1-7: "I am the soul of darkness, Abrasax, the eternal one, Michaēl, but my true name is Thōouth, Thōouth." One papyrus titled the "Monad" or the "Eighth Book of Moses" (PGM XIII. 1–343) contains an invocation to a supreme creator God; Abrasax is given as being the name of this God in the language of the baboons. The papyrus goes on to describe a cosmogonic myth about Abrasax, describing how he created the Ogdoad by laughing. His first laughter created light; his second divided the primordial waters; his third created the mind; his fourth created fertility and procreation; his fifth created fate; his sixth created time (as the sun and moon); and his seventh and final laughter created the soul. Then, from various sounds made by Abrasax, there arose the serpent Python who "foreknew all things", the first man (or Fear), and the god Iaō, "who is lord of all". The man fought with Iaō, and Abrasax declared that Iaō's power would derive from both of the others, and that Iaō would take precedence over all the other gods. This text also describes Helios as an archangel of God/Abrasax. The Leyden Papyrus recommends that this invocation be pronounced to the moon: The magic word "Ablanathanalba", which reads in Greek the same backward as forward, also occurs in the Abrasax-stones as well as in the magic papyri. This word is usually conceded to be derived from the Hebrew (Aramaic), meaning "Thou art our father" (אב לן את), and also occurs in connection with Abrasax; the following inscription is found upon a metal plate in the Karlsruhe Museum: In literature In popular culture In the 2022 point n' click videogame The Excavation of Hob's Barrow, by developer Cloak and Dagger Games and published by Wadjet Eye Games, Abraxas is a god/demon closely inspired by the original Gnostic Mythology. In Marvel comics, the character Abraxas embodies the destruction of the multiverse (first appearance: 2001). "Mt. Abraxas" is the title of the first track of occult rock band Uncle Acid & the Deadbeats's third studio album Mind Control (2013). Abraxas appears as a demon in Charmed season 2 (1999–2000). Abraxas appears as a demon in Supernatural season 14 (2018–2019). In the 2008 visual novel 11eyes: Tsumi to Batsu to Aganai no Shōjo, Kukuri can summon her soul in the form of a chained guardian angel named Abraxas. When released from his chains, he becomes a godlike entity named Demiurge. The 2018 video game Darksiders III features a demon named Abraxis. South Korean band BTS's videos frequently mention Abraxas and much of their storyline is based around the deity. In 1970, the second studio album of Latin rock band Santana was named Abraxas, derived from a passage in the Hermann Hesse novel Demian. In 1987 The Abraxas Foundation was founded by Boyd Rice as a Social Darwinist think tank. In the 2018 thriller Mandy, the "horn of Abraxas" is a sort of stone flute with magical properties. Brother Swan uses it to summon the Black Skulls, a demonic biker gang. In the 2019 role-playing game Fire Emblem: Three Houses, Abraxas is the name of a damage-dealing Faith spell. In the 2010 song "Lead Poisoning" by Alkaline Trio, Matt Skiba sings the line "Now I pray to Abraxas my soul to keep". In season 1, episode 2 of Netflix's 2020 animated show The Midnight Gospel the main character, Clancy Gilroy, purchases an avatar named Braxis, which he then uses to explore alternate universes. Braxis looks like the traditional images of Abraxas where the creature has a human body and the head of a rooster. Like the traditional images, Braxis has serpents for legs and his arms are also like those in traditional representations. In the 2018 video game Assassin's Creed Odyssey, Abraxas is the name of the legendary fiery horse the player acquires if they reach the Tier 1 level in the hierarchy of mercenaries. In J. K. Rowling's Harry Potter series (1997–2007), Abraxas is the name of Lucius Malfoy's father, as well as the name of a race of winged horses in the same fictional world. In the 2015 sci-fi/action movie Jupiter Ascending, the most powerful family in the Cosmos known as the House of Abrasax. Abraxas, in the Gnostic role of Great Archon, is the antagonist of the 2021 video game Cruelty Squad. In the 2021 TV-adaptation of Isaac Asimov's Foundation series, the Abraxas Conjecture is the name of the mathematical proof that Gaal Dornick solves using Kalle's Ninth Proof of Folding. In Sarah J. Maas' Throne of Glass series (2014–2018), the similarly-named Abraxos is the wyvern mount of Manon Blackbeak. In the 1992 Discworld novel Small Gods by Terry Pratchett, Abraxas was an Ephebian philosopher who wrote about the nature of gods in his scroll On Religion, theorising that gods died if belief in them is diverted towards a rigid, hierarchical church structure, as had nearly happened with the Great God Om due to fear of the Omnian Quisition. Having survived being struck by lightning fifteen times as a result, he earned the nickname 'Charcoal'. In the Shin Megami Tensei video game franchise (first release: 1987), Abraxas is a demon. In the 2020 video game Genshin Impact, Abrax (also known as Aberaku no Mikoto, ) was a historical figure in Enkanomiya who created the Dainichi Mikoshi, an artificial sun device whose name is described as meaning "chariot of the sun". In the 1997 animated series Revolutionary Girl Utena by animation studio Be-Papas, Abraxas is referenced in the series soundtrack. The title being; "The God's Name Is Abraxas". In the 1999 movie Adolescence of Utena by animation studio Be-Papas, Abraxas is referenced in the film's soundtrack. The title of the song being; "Abraxas ~ Sunny Garden". In 2019, electronic music producers Seven Lions and Dimibo formed a psytrance trio called “Abraxis.” The project consists of a back story in which Reginald Abraxis formed the Abraxis Institute, in order to help people explore their full potential and achieve self-actualization.

AWK

AWK (awk) is a domain-specific language designed for text processing and typically used as a data extraction and reporting tool. Like sed and grep, it is a filter, and is a standard feature of most Unix-like operating systems. The AWK language is a data-driven scripting language consisting of a set of actions to be taken against streams of textual data – either run directly on files or used as part of a pipeline – for purposes of extracting or transforming text, such as producing formatted reports. The language extensively uses the string datatype, associative arrays (that is, arrays indexed by key strings), and regular expressions. While AWK has a limited intended application domain and was especially designed to support one-liner programs, the language is Turing-complete, and even the early Bell Labs users of AWK often wrote well-structured large AWK programs. AWK was created at Bell Labs in the 1970s, and its name is derived from the surnames of its authors: Alfred Aho, Peter Weinberger, and Brian Kernighan. The acronym is pronounced the same as the name of the bird species auk, which is illustrated on the cover of The AWK Programming Language. When written in all lowercase letters, as awk, it refers to the Unix or Plan 9 program that runs scripts written in the AWK programming language. History AWK was initially developed in 1977 by Alfred Aho (author of egrep), Peter J. Weinberger (who worked on tiny relational databases), and Brian Kernighan. AWK takes its name from their respective initials. According to Kernighan, one of the goals of AWK was to have a tool that would easily manipulate both numbers and strings. AWK was also inspired by Marc Rochkind's programming language that was used to search for patterns in input data, and was implemented using yacc. As one of the early tools to appear in Version 7 Unix, AWK added computational features to a Unix pipeline besides the Bourne shell, the only scripting language available in a standard Unix environment. It is one of the mandatory utilities of the Single UNIX Specification, and is required by the Linux Standard Base specification. AWK was significantly revised and expanded in 1985–88, resulting in the GNU AWK implementation written by Paul Rubin, Jay Fenlason, and Richard Stallman, released in 1988. GNU AWK may be the most widely deployed version because it is included with GNU-based Linux packages. GNU AWK has been maintained solely by Arnold Robbins since 1994. Brian Kernighan's nawk (New AWK) source was first released in 1993 unpublicized, and publicly since the late 1990s; many BSD systems use it to avoid the GPL license. AWK was preceded by sed (1974). Both were designed for text processing. They share the line-oriented, data-driven paradigm, and are particularly suited to writing one-liner programs, due to the implicit main loop and current line variables. The power and terseness of early AWK programs – notably the powerful regular expression handling and conciseness due to implicit variables, which facilitate one-liners – together with the limitations of AWK at the time, were important inspirations for the Perl language (1987). In the 1990s, Perl became very popular, competing with AWK in the niche of Unix text-processing languages. Structure of AWK programs An AWK program is a series of pattern action pairs, written as: condition { action } condition { action } ... where condition is typically an expression and action is a series of commands. The input is split into records, where by default records are separated by newline characters so that the input is split into lines. The program tests each record against each of the conditions in turn, and executes the action for each expression that is true. Either the condition or the action may be omitted. The condition defaults to matching every record. The default action is to print the record. This is the same pattern-action structure as sed. In addition to a simple AWK expression, such as foo == 1 or /^foo/, the condition can be BEGIN or END causing the action to be executed before or after all records have been read, or pattern1, pattern2 which matches the range of records starting with a record that matches pattern1 up to and including the record that matches pattern2 before again trying to match against pattern1 on subsequent lines. In addition to normal arithmetic and logical operators, AWK expressions include the tilde operator, ~, which matches a regular expression against a string. As handy syntactic sugar, /regexp/ without using the tilde operator matches against the current record; this syntax derives from sed, which in turn inherited it from the ed editor, where / is used for searching. This syntax of using slashes as delimiters for regular expressions was subsequently adopted by Perl and ECMAScript, and is now common. The tilde operator was also adopted by Perl. Commands AWK commands are the statements that are substituted for action in the examples above. AWK commands can include function calls, variable assignments, calculations, or any combination thereof. AWK contains built-in support for many functions; many more are provided by the various flavors of AWK. Also, some flavors support the inclusion of dynamically linked libraries, which can also provide more functions. The print command The print command is used to output text. The output text is always terminated with a predefined string called the output record separator (ORS) whose default value is a newline. The simplest form of this command is: print This displays the contents of the current record. In AWK, records are broken down into fields, and these can be displayed separately: print $1 Displays the first field of the current record print $1, $3 Displays the first and third fields of the current record, separated by a predefined string called the output field separator (OFS) whose default value is a single space character Although these fields ($X) may bear resemblance to variables (the $ symbol indicates variables in Perl), they actually refer to the fields of the current record. A special case, $0, refers to the entire record. In fact, the commands "print" and "print $0" are identical in functionality. The print command can also display the results of calculations and/or function calls: /regex_pattern/ { # Actions to perform in the event the record (line) matches the above regex_pattern print 3+2 print foobar(3) print foobar(variable) print sin(3-2) } Output may be sent to a file: /regex_pattern/ { # Actions to perform in the event the record (line) matches the above regex_pattern print "expression" > "file name" } or through a pipe: /regex_pattern/ { # Actions to perform in the event the record (line) matches the above regex_pattern print "expression" | "command" } Built-in variables Awk's built-in variables include the field variables: $1, $2, $3, and so on ($0 represents the entire record). They hold the text or values in the individual text-fields in a record. Other variables include: NR: Number of Records. Keeps a current count of the number of input records read so far from all data files. It starts at zero, but is never automatically reset to zero. FNR: File Number of Records. Keeps a current count of the number of input records read so far in the current file. This variable is automatically reset to zero each time a new file is started. NF: Number of Fields. Contains the number of fields in the current input record. The last field in the input record can be designated by $NF, the 2nd-to-last field by $(NF-1), the 3rd-to-last field by $(NF-2), etc. FILENAME: Contains the name of the current input-file. FS: Field Separator. Contains the "field separator" used to divide fields in the input record. The default, "white space", allows any sequence of space and tab characters. FS can be reassigned with another character or character sequence to change the field separator. RS: Record Separator. Stores the current "record separator" character. Since, by default, an input line is the input record, the default record separator character is a "newline". OFS: Output Field Separator. Stores the "output field separator", which separates the fields when Awk prints them. The default is a "space" character. ORS: Output Record Separator. Stores the "output record separator", which separates the output records when Awk prints them. The default is a "newline" character. OFMT: Output Format. Stores the format for numeric output. The default format is "%.6g". Variables and syntax Variable names can use any of the characters [A-Za-z0-9_], with the exception of language keywords. The operators + - * / represent addition, subtraction, multiplication, and division, respectively. For string concatenation, simply place two variables (or string constants) next to each other. It is optional to use a space in between if string constants are involved, but two variable names placed adjacent to each other require a space in between. Double quotes delimit string constants. Statements need not end with semicolons. Finally, comments can be added to programs by using # as the first character on a line. User-defined functions In a format similar to C, function definitions consist of the keyword function, the function name, argument names and the function body. Here is an example of a function. function add_three (number) { return number + 3 } This statement can be invoked as follows: (pattern) { print add_three(36) # Outputs '''39''' } Functions can have variables that are in the local scope. The names of these are added to the end of the argument list, though values for these should be omitted when calling the function. It is convention to add some whitespace in the argument list before the local variables, to indicate where the parameters end and the local variables begin. Examples Hello World Here is the customary "Hello, world" program written in AWK: BEGIN { print "Hello, world!" exit } Print lines longer than 80 characters Print all lines longer than 80 characters. Note that the default action is to print the current line. length($0) > 80 Count words Count words in the input and print the number of lines, words, and characters (like wc): { words += NF chars += length + 1 # add one to account for the newline character at the end of each record (line) } END { print NR, words, chars } As there is no pattern for the first line of the program, every line of input matches by default, so the increment actions are executed for every line. Note that words += NF is shorthand for words = words + NF. Sum last word { s += $NF } END { print s + 0 } s is incremented by the numeric value of $NF, which is the last word on the line as defined by AWK's field separator (by default, white-space). NF is the number of fields in the current line, e.g. 4. Since $4 is the value of the fourth field, $NF is the value of the last field in the line regardless of how many fields this line has, or whether it has more or fewer fields than surrounding lines. $ is actually a unary operator with the highest operator precedence. (If the line has no fields, then NF is 0, $0 is the whole line, which in this case is empty apart from possible white-space, and so has the numeric value 0.) At the end of the input the END pattern matches, so s is printed. However, since there may have been no lines of input at all, in which case no value has ever been assigned to s, it will by default be an empty string. Adding zero to a variable is an AWK idiom for coercing it from a string to a numeric value. (Concatenating an empty string is to coerce from a number to a string, e.g. s "". Note, there's no operator to concatenate strings, they're just placed adjacently.) With the coercion the program prints "0" on an empty input, without it, an empty line is printed. Match a range of input lines NR % 4 == 1, NR % 4 == 3 { printf "%6d %s\n", NR, $0 } The action statement prints each line numbered. The printf function emulates the standard C printf and works similarly to the print command described above. The pattern to match, however, works as follows: NR is the number of records, typically lines of input, AWK has so far read, i.e. the current line number, starting at 1 for the first line of input. % is the modulo operator. NR % 4 == 1 is true for the 1st, 5th, 9th, etc., lines of input. Likewise, NR % 4 == 3 is true for the 3rd, 7th, 11th, etc., lines of input. The range pattern is false until the first part matches, on line 1, and then remains true up to and including when the second part matches, on line 3. It then stays false until the first part matches again on line 5. Thus, the program prints lines 1,2,3, skips line 4, and then 5,6,7, and so on. For each line, it prints the line number (on a 6 character-wide field) and then the line contents. For example, when executed on this input: Rome Florence Milan Naples Turin Venice The previous program prints: 1 Rome 2 Florence 3 Milan 5 Turin 6 Venice Printing the initial or the final part of a file As a special case, when the first part of a range pattern is constantly true, e.g. 1, the range will start at the beginning of the input. Similarly, if the second part is constantly false, e.g. 0, the range will continue until the end of input. For example, /^--cut here--$/, 0 prints lines of input from the first line matching the regular expression ^--cut here--$, that is, a line containing only the phrase "--cut here--", to the end. Calculate word frequencies Word frequency using associative arrays: BEGIN { FS="[^a-zA-Z]+" } { for (i=1; i<=NF; i++) words[tolower($i)]++ } END { for (i in words) print i, words[i] } The BEGIN block sets the field separator to any sequence of non-alphabetic characters. Note that separators can be regular expressions. After that, we get to a bare action, which performs the action on every input line. In this case, for every field on the line, we add one to the number of times that word, first converted to lowercase, appears. Finally, in the END block, we print the words with their frequencies. The line for (i in words) creates a loop that goes through the array words, setting i to each subscript of the array. This is different from most languages, where such a loop goes through each value in the array. The loop thus prints out each word followed by its frequency count. tolower was an addition to the One True awk (see below) made after the book was published. Match pattern from command line This program can be represented in several ways. The first one uses the Bourne shell to make a shell script that does everything. It is the shortest of these methods: #!/bin/sh pattern="$1" shift awk '/'"$pattern"'/ { print FILENAME ":" $0 }' "$@" The $pattern in the awk command is not protected by single quotes so that the shell does expand the variable but it needs to be put in double quotes to properly handle patterns containing spaces. A pattern by itself in the usual way checks to see if the whole line ($0) matches. FILENAME contains the current filename. awk has no explicit concatenation operator; two adjacent strings concatenate them. $0 expands to the original unchanged input line. There are alternate ways of writing this. This shell script accesses the environment directly from within awk: #!/bin/sh export pattern="$1" shift awk '$0 ~ ENVIRON["pattern"] { print FILENAME ":" $0 }' "$@" This is a shell script that uses ENVIRON, an array introduced in a newer version of the One True awk after the book was published. The subscript of ENVIRON is the name of an environment variable; its result is the variable's value. This is like the getenv function in various standard libraries and POSIX. The shell script makes an environment variable pattern containing the first argument, then drops that argument and has awk look for the pattern in each file. ~ checks to see if its left operand matches its right operand; !~ is its inverse. Note that a regular expression is just a string and can be stored in variables. The next way uses command-line variable assignment, in which an argument to awk can be seen as an assignment to a variable: #!/bin/sh pattern="$1" shift awk '$0 ~ pattern { print FILENAME ":" $0 }' "pattern=$pattern" "$@" Or You can use the -v var=value command line option (e.g. awk -v pattern="$pattern" ...). Finally, this is written in pure awk, without help from a shell or without the need to know too much about the implementation of the awk script (as the variable assignment on command line one does), but is a bit lengthy: BEGIN { pattern = ARGV[1] for (i = 1; i < ARGC; i++) # remove first argument ARGV[i] = ARGV[i + 1] ARGC-- if (ARGC == 1) { # the pattern was the only thing, so force read from standard input (used by book) ARGC = 2 ARGV[1] = "-" } } $0 ~ pattern { print FILENAME ":" $0 } The BEGIN is necessary not only to extract the first argument, but also to prevent it from being interpreted as a filename after the BEGIN block ends. ARGC, the number of arguments, is always guaranteed to be ≥1, as ARGV[0] is the name of the command that executed the script, most often the string "awk". Also note that ARGV[ARGC] is the empty string, "". # initiates a comment that expands to the end of the line. Note the if block. awk only checks to see if it should read from standard input before it runs the command. This means that awk 'prog' only works because the fact that there are no filenames is only checked before prog is run! If you explicitly set ARGC to 1 so that there are no arguments, awk will simply quit because it feels there are no more input files. Therefore, you need to explicitly say to read from standard input with the special filename -. Self-contained AWK scripts On Unix-like operating systems self-contained AWK scripts can be constructed using the shebang syntax. For example, a script that prints the content of a given file may be built by creating a file named print.awk with the following content: #!/usr/bin/awk -f { print $0 } It can be invoked with: ./print.awk <filename> The -f tells AWK that the argument that follows is the file to read the AWK program from, which is the same flag that is used in sed. Since they are often used for one-liners, both these programs default to executing a program given as a command-line argument, rather than a separate file. Versions and implementations AWK was originally written in 1977 and distributed with Version 7 Unix. In 1985 its authors started expanding the language, most significantly by adding user-defined functions. The language is described in the book The AWK Programming Language, published 1988, and its implementation was made available in releases of UNIX System V. To avoid confusion with the incompatible older version, this version was sometimes called "new awk" or nawk. This implementation was released under a free software license in 1996 and is still maintained by Brian Kernighan (see external links below). Old versions of Unix, such as UNIX/32V, included awkcc, which converted AWK to C. Kernighan wrote a program to turn awk into C++; its state is not known. BWK awk, also known as nawk, refers to the version by Brian Kernighan. It has been dubbed the "One True AWK" because of the use of the term in association with the book that originally described the language and the fact that Kernighan was one of the original authors of AWK. FreeBSD refers to this version as one-true-awk. This version also has features not in the book, such as tolower and ENVIRON that are explained above; see the FIXES file in the source archive for details. This version is used by, for example, Android, FreeBSD, NetBSD, OpenBSD, macOS, and illumos. Brian Kernighan and Arnold Robbins are the main contributors to a source repository for nawk: . gawk (GNU awk) is another free-software implementation and the only implementation that makes serious progress implementing internationalization and localization and TCP/IP networking. It was written before the original implementation became freely available. It includes its own debugger, and its profiler enables the user to make measured performance enhancements to a script. It also enables the user to extend functionality with shared libraries. Some Linux distributions include gawk as their default AWK implementation. As of version 5.2 (September 2022) gawk includes a persistent memory feature that can remember script-defined variables and functions from one invocation of a script to the next and pass data between unrelated scripts, as described in the Persistent-Memory gawk User Manual: . gawk-csv. The CSV extension of gawk provides facilities for handling input and output CSV formatted data. mawk is a very fast AWK implementation by Mike Brennan based on a bytecode interpreter. libmawk is a fork of mawk, allowing applications to embed multiple parallel instances of awk interpreters. awka (whose front end is written atop the mawk program) is another translator of AWK scripts into C code. When compiled, statically including the author's libawka.a, the resulting executables are considerably sped up and, according to the author's tests, compare very well with other versions of AWK, Perl, or Tcl. Small scripts will turn into programs of 160–170 kB. tawk (Thompson AWK) is an AWK compiler for Solaris, DOS, OS/2, and Windows, previously sold by Thompson Automation Software (which has ceased its activities). Jawk is a project to implement AWK in Java, hosted on SourceForge. Extensions to the language are added to provide access to Java features within AWK scripts (i.e., Java threads, sockets, collections, etc.). xgawk is a fork of gawk that extends gawk with dynamically loadable libraries. The XMLgawk extension was integrated into the official GNU Awk release 4.1.0. QSEAWK is an embedded AWK interpreter implementation included in the QSE library that provides embedding application programming interface (API) for C and C++. libfawk is a very small, function-only, reentrant, embeddable interpreter written in C BusyBox includes an AWK implementation written by Dmitry Zakharov. This is a very small implementation suitable for embedded systems. CLAWK by Michael Parker provides an AWK implementation in Common Lisp, based upon the regular expression library of the same author.

Álfheimr

In Norse cosmology, Álfheimr (Old Norse: , "Land of the Elves" or "Elfland"; anglicized as Alfheim), also called "Ljósálfheimr" ( , "home of the Light Elves"), is home of the Light Elves. Attestations Álfheim as an abode of the Elves is mentioned only twice in Old Norse texts. The eddic poem Grímnismál describes twelve divine dwellings beginning the stanza 5 with: Ýdalir call they     the place where Ull A hall for himself hath set; And Álfheim the gods     to Frey once gave As a tooth-gift in ancient times. A tooth-gift was a gift given to an infant on the cutting of the first tooth. In the 12th century eddic prose Gylfaginning, Snorri Sturluson relates it in the stanza 17 as the first of a series of abodes in heaven: That which is called Álfheim is one, where dwell the peoples called ljósálfar [Light Elves]; but the dökkálfar [Dark Elves] dwell down in the earth, and they are unlike in appearance, but by far more unlike in nature. The Light-elves are fairer to look upon than the sun, but the Dark-elves are blacker than pitch. The account later, in speaking of a hall in the Highest Heaven called Gimlé that shall survive when heaven and earth have died, explains: It is said that another heaven is to the southward and upward of this one, and it is called Andlang [Andlangr 'Endlong'] but the third heaven is yet above that, and it is called Vídbláin [Vídbláinn 'Wide-blue'] and in that heaven we think this abode is. But we believe that none but Light-Elves inhabit these mansions now. It is not indicated whether these heavens are identical to Álfheim or distinct. Some texts read Vindbláin (Vindbláinn 'Wind-blue') instead of Vídbláin. Modern commentators speculate (or sometimes state as fact) that Álfheim was one of the nine worlds (heima) mentioned in stanza 2 of the eddic poem Völuspá.

Agate

Agate () is a common rock formation, consisting of chalcedony and quartz as its primary components, with a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. The ornamental use of agate was common in Ancient Greece, in assorted jewelry and in the seal stones of Greek warriors, while bead necklaces with pierced and polished agate date back to the 3rd millennium BCE in the Indus Valley civilisation. Etymology The stone was given its name by Theophrastus, a Greek philosopher and naturalist, who discovered the stone along the shore line of the Dirillo River or Achates () in Sicily, sometime between the 4th and 3rd centuries BCE. Formation and properties Agate minerals have the tendency to form on or within pre-existing rocks, creating difficulties in accurately determining their time of formation. Their host rocks have been dated to have formed as early as the Archean Eon. Agates are most commonly found as nodules within the cavities of volcanic rocks. These cavities are formed from the gases trapped within the liquid volcanic material forming vesicles. Cavities are then filled in with silica-rich fluids from the volcanic material, layers are deposited on the walls of the cavity slowly working their way inwards. The first layer deposited on the cavity walls is commonly known as the priming layer. Variations in the character of the solution or in the conditions of deposition may cause a corresponding variation in the successive layers. These variations in layers result in bands of chalcedony, often alternating with layers of crystalline quartz forming banded agate. Hollow agates can also form due to the deposition of liquid-rich silica not penetrating deep enough to fill the cavity completely. Agate will form crystals within the reduced cavity, and the apex of each crystal may point towards the center of the cavity. The priming layer is often dark green, but can be modified by iron oxide resulting in a rust like appearance. Agate is very durable, and is often found detached from its host matrix, which has eroded away. Once removed, the outer surface is usually pitted and rough from filling the cavity of its former matrix. Agates have also been found in sedimentary rocks, normally in limestone or dolomite; these sedimentary rocks acquire cavities often from decomposed branches or other buried organic material. If silica-rich fluids are able to penetrate into these cavities agates can be formed. Types Lace agate is a variety that exhibits a lace-like pattern with forms such as eyes, swirls, bands or zigzags. Blue lace agate is found in Africa and is especially hard. Crazy lace agate, typically found in Mexico, is often brightly colored with a complex pattern, demonstrating randomized distribution of contour lines and circular droplets, scattered throughout the rock. The stone is typically coloured red and white but is also seen to exhibit yellow and grey combinations as well. Moss agate, as the name suggests, exhibits a moss-like pattern and is of a greenish colour. The coloration is not created by any vegetative growth, but rather through the mixture of chalcedony and oxidized iron hornblende. Dendritic agate also displays vegetative features, including fern-like patterns formed due to the presence of manganese and iron oxides. Turritella agate (Elimia tenera) is formed from the shells of fossilized freshwater Turritella gastropods with elongated spiral shells. Similarly, coral, petrified wood, porous rocks and other organic remains can also form agate. Coldwater agates, such as the Lake Michigan cloud agate, did not form under volcanic processes, but instead formed within the limestone and dolomite strata of marine origin. Like volcanic-origin agates, Coldwater agates formed from silica gels that lined pockets and seams within the bedrock. These agates are typically less colorful, with banded lines of grey and white chalcedony. Greek agate is a name given to pale white to tan colored agate found in the former Greek colony of Sicily as early as 400 BCE. The Greeks used it for making jewelry and beads. Brazilian agate is found as sizable geodes of layered nodules. These occur in brownish tones inter-layered with white and gray. It is often dyed in various colors for ornamental purposes. Polyhedroid agate forms in a flat-sided shape similar to a polyhedron. When sliced, it often shows a characteristic layering of concentric polygons. It has been suggested that growth is not crystallographically controlled but is due to the filling-in of spaces between pre-existing crystals which have since dissolved. Iris agate is a finely-banded and usually colorless agate, that when thinly sliced, exhibits spectral decomposition of white light into its constituent colors, requiring 400 to up to 30,000 bands per inch. Other forms of agate include Holley blue agate (also spelled "Holly blue agate"), a rare dark blue ribbon agate found only near Holley, Oregon; Lake Superior agate; Carnelian agate (has reddish hues); Botswana agate; plume agate; condor agate; tube agate containing visible flow channels or pinhole-sized "tubes"; fortification agate with contrasting concentric banding reminiscent of defensive ditches and walls around ancient forts; Binghamite, a variety found only on the Cuyuna iron range (near Crosby) in Crow Wing County, Minnesota; fire agate showing an iridescent, internal flash or "fire," the result of a layer of clear agate over a layer of hydrothermally deposited hematite; Patuxent River stone, a red and yellow form of agate only found in Maryland; and enhydro agate, which contains tiny inclusions of water, sometimes with air bubbles. Agate is a beautiful and versatile gemstone that is often used in jewelry making. It is a type of chalcedony, a mineral in the quartz family, and is known for its colorful, banded patterns and wide range of hues. Here are a few reasons why agate makes amazing jewelry: Durability: Agate is a relatively hard and durable gemstone, which makes it a good choice for jewelry that will be worn frequently or subjected to rough handling. It has a Mohs hardness rating of 6.5-7, which means it is resistant to scratching and chipping. Versatility: Agate comes in a wide range of colors, including shades of red, orange, yellow, green, blue, purple, and pink, as well as black and white. This makes it a versatile choice for a wide variety of jewelry styles and color schemes. Metaphysical properties: Agate is believed to have grounding and stabilizing properties, and is often used to promote balance, harmony, and calm. It is also said to enhance mental function and increase energy. Affordability: Agate is generally more affordable than other gemstones, which makes it a good choice for those on a budget. Uses Agate is one of the most common materials used in the art of hardstone carving, and has been recovered at a number of ancient sites, indicating its widespread use in the ancient world; for example, archaeological recovery at the Knossos site on Crete illustrates its role in Bronze Age Minoan culture. It has also been used for centuries for leather burnishing tools. The decorative arts use it to make ornaments such as pins, brooches or other types of jewellery, paper knives, inkstands, marbles and seals. Agate is also still used today for decorative displays, cabochons, beads, carvings and Intarsia art as well as face-polished and tumble-polished specimens of varying size and origin. Idar-Oberstein was one of the centers which made use of agate on an industrial scale. Where in the beginning locally found agates were used to make all types of objects for the European market, this became a globalized business around the turn of the 20th century: Idar-Oberstein imported large quantities of agate from Brazil, as ship's ballast. Making use of a variety of proprietary chemical processes, they produced colored beads that were sold around the globe. Agates have long been used in arts and crafts. The sanctuary of a Presbyterian church in Yachats, Oregon, has six windows with panes made of agates collected from the local beaches. Industrial uses of agate exploit its hardness, ability to retain a highly polished surface finish and resistance to chemical attack. It has traditionally been used to make knife-edge bearings for laboratory balances and precision pendulums, and sometimes to make mortars and pestles to crush and mix chemicals. Health impact Respiratory diseases such as silicosis, and a higher incidence of tuberculosis among workers involved in the agate industry, have been studied in India and China.

Ahmed III

Ahmed III (, Aḥmed-i sālis) (30 December 16731 July 1736) was Sultan of the Ottoman Empire and a son of Sultan Mehmed IV (r. 1648–1687). His mother was Gülnuş Sultan, originally named Evmania Voria, who was an ethnic Greek. He was born at Hacıoğlu Pazarcık, in Dobruja. He succeeded to the throne in 1703 on the abdication of his brother Mustafa II (1695–1703). Nevşehirli Damat İbrahim Pasha and the Sultan's daughter, Fatma Sultan (wife of the former) directed the government from 1718 to 1730, a period referred to as the Tulip Era. The first days of Ahmed III's reign passed with efforts to appease the janissaries who were completely disciplined. However, he was not effective against the janissaries who made him sultan. Çorlulu Ali Pasha, who Ahmed brought to the Grand Vizier, tried to help him in administrative matters, made new arrangements for the treasury and Sultan. He supported Ahmed in his fight with his rivals. Early life and education Sultan Ahmed was born on 30 December 1673. His father was Sultan Mehmed IV, and his mother was Gülnuş Sultan, originally named Evmenia. His birth occurred in Hacıoğlupazarı, where Mehmed stayed to hunt on his return from Poland in 1673, while Gülnuş was pregnant at that time. In 1675, He and his brother, Prince Mustafa (future Mustafa II) were circumcised. During the same ceremony their sisters Hatice Sultan and Fatma Sultan were married to Musahip Mustafa Pasha and Kara Mustafa Pasha respectively. The celebrations lasted 20 days. He grew up in the Edirne Palace. His schooling began during one of the sporadic visits of the court to Istanbul, following a courtly ceremony called bad-i basmala, which took place on 9 August 1679 in the Istavroz Palace. He was brought up in the imperial harem in Edirne with a traditional princely education, studying the Qur’an, the hadiths (traditions of Prophet Muhammad), and the fundamentals of Islamic sciences, history, poetry and music under the supervision of private tutors. One of his tutors was chief mufti Feyzullah Efendi. Ahmed was apparently curious and intellectual in nature, spending most of his time reading and practising calligraphy. The poems that he wrote manifest his profound knowledge of poetry, history, Islamic theology and philosophy. He was also interested in calligraphy, which he had studied with the leading court calligraphers, primarily with Hafız Osman Efendi (died 1698), who influenced his art immensely, and, therefore, practiced it because of the influence of his elder brother, the future Sultan Mustafa II, who also became a notable calligrapher. During his princehood in Edirne, Ahmed made friends with a bright officer-scribe, Ibrahim, from the city of Nevşehir, who was to become one of the outstanding Grand Viziers of his future reign. From 1687, following the deposition of his father, he lived in isolation for sixteen years in the palaces of Edirne and Istanbul. During this period he dedicated himself to calligraphy and intellectual activities. Reign Accession The Edirne succession occurred between 19 August to 23 August. Under Mustafa, Istanbul had been out of control for a long time. As arrests and executions mounted, theft and robbery incidents became common. The people were dissatisfied with the poor governing of the Empire. Mustafa was deposed by the Janissaries and Ahmed, who succeeded him to the throne on 22 August 1703. The first Friday salute was held in Bayezid Mosque. Fındıklılı Mehmed Ağa welcomed the new sultan at the Harem gate on the Hasoda side, entered the arm, brought him to the Cardigan-i Saadet Department and placed them on the throne, and were among the first to pay tribute to him. As part of the fief system, Ahmed reorganized the land law in 1705. Bringing order to land ownership reduced the crime wave and brought peace to the troubled Empire. Due to his ardent support of the new laws, Ahmed was given the title 'law-giver', a title given to only three sultans earlier, Bayezid II (r.1481-1512), Selim I (r.1512-1520) and Suleyman the Magnificent (r.1520-1566). In the first three years of his reign, Ahmed appointed four separate Grand Viziers. However, the government only gained stability after the appointment of Çorlulu Ali Pasha in May 1706. Russo-Turkish War of 1710–11 Ahmed III cultivated good relations with France, doubtless in view of Russia's menacing attitude. He afforded refuge in Ottoman territory to Charles XII of Sweden (1682–1718) after the Swedish defeat at the hands of Peter I of Russia (1672–1725) in the Battle of Poltava of 1709. In 1710 Charles XII convinced Sultan Ahmed III to declare war against Russia, and the Ottoman forces under Baltacı Mehmet Pasha won a major victory at the Battle of Prut. In the aftermath, Russia returned Azov back to the Ottomans, agreed to demolish the fortress of Taganrog and others in the area, and to stop interfering in the affairs of the Polish–Lithuanian Commonwealth. Forced against his will into war with Russia, Ahmed III came nearer than any Ottoman sovereign before or since to breaking the power of his northern rival, whose armies his grand vizier Nevşehirli Damat İbrahim Pasha succeeded in completely surrounding at the Pruth River Campaign in 1711. The subsequent Ottoman victories against Russia enabled the Ottoman Empire to advance to Moscow, had the Sultan wished. However, this was halted as a report reached Istanbul that the Safavids were invading the Ottoman Empire, causing a period of panic, turning the Sultan's attention away from Russia. Wars with Venice and Austria On 9 December 1714, war was declared on Venice, and an army under Silahdar Damat Ali Pasha's command, the Ottomans managed to recover the whole Morea (Peloponnese) from Venice through coordinated operations of the army and navy. This success alarmed Austria and in April 1716, Emperor Charles VI provoked the Porte into a declaration of war. The unsuccessful battle, also commanded by Silahdar Ali Pasha, ended with the treaty of Passarovitz, signed on 21 July 1718, according to which Belgrade, Banat, and little Wallachia were ceded to Austria. This failure was a real disappointment for Ahmed and after the bad conditions imposed by this treaty, Istanbul's economy suffered from increased inflation and all of its attendant evils. Ibrahim Pasha who was the second leading figure of the empire after Ahmed had joined the Morea campaign in 1715, and was appointed as the city of Nish's minister of finance the following year. This post helped him realize the downturn of the state's finances and, due to his insight of this sensitive financial situation he avoided war as much as possible during his vizierate. Ibrahim Pasha's policy of peace suited Ahmed as well since he had no wish to lead any military campaigns, in addition to the fact that his interest in art and culture made him reluctant to leave his Istanbul. Character of Ahmed's rule While shooting competitions were held in Okmeydanı with the idea of increasing the morale of the soldiers and the people, a new warship was launched in Tersane-i Amir. He tried three grand viziers at short intervals. Instead of Hasan Pasha, he appointed Kalaylikoz Ahmed Pasha on 24 September 1704, and Baltacı Mehmed Pasha on 25 December 1704. It was a great pleasure that the ambassadors of Iran and Austria, who came from 1706 to 1707. In 1707, the conspiracy led by Eyüplü Ali Ağa was unearthed to bring the sultan off the throne. Necks were cut in front of the Bab-I-Hümayun. Ahmed III left the finances of the Ottoman Empire in a flourishing condition, which had remarkably been obtained without excessive taxation or extortion procedures. He was a cultivated patron of literature and art, and it was in his time that the first printing press authorized to use the Arabic or Turkish languages was set up in Istanbul, operated by Ibrahim Muteferrika (while the printing press had been introduced to Constantinople in 1480, all works published before 1729 were in Greek, Armenian, or Hebrew). It was in this reign that an important change in the government of the Danubian Principalities was introduced: previously, the Porte had appointed Hospodars, usually native Moldavian and Wallachian boyars, to administer those provinces; after the Russian campaign of 1711, during which Peter the Great found an ally in Moldavia Prince Dimitrie Cantemir, the Porte began overtly deputizing Phanariote Greeks in that region, and extended the system to Wallachia after Prince Stefan Cantacuzino established links with Eugene of Savoy. The Phanariotes constituted a kind of Dhimmi nobility, which supplied the Porte with functionaries in many important departments of the state. Relations with the Mughal Empire Jahandar Shah In the year 1712, the Mughal Emperor Jahandar Shah, the grandson of Aurangzeb sent gifts to the Ottoman Sultan Ahmed III and referred to himself as the Ottoman Sultan's devoted admirer. Farrukhsiyar The Mughal Emperor Farrukhsiyar a grandson of Aurangzeb, is also known to have sent a letter to the Ottomans but this time it was received by the Grand Vizier Nevşehirli Damad Ibrahim Pasha providing a graphic description of the efforts of the Mughal commander Syed Hassan Ali Khan Barha against the Rajput and Maratha rebellion. Deposition Sultan Ahmed III had become unpopular by reason of the excessive pomp and costly luxury in which he and his principal officers indulged; on 20 September 1730, a mutinous riot of seventeen Janissaries, led by the Albanian Patrona Halil, was aided by the citizens as well as the military until it swelled into an insurrection in front of which the Sultan was forced to give up the throne. Ahmed voluntarily led his nephew Mahmud I (1730–54) to the seat of sovereignty and paid allegiance to him as Sultan of the Empire. He then retired to the Kafes previously occupied by Mahmud and died at Topkapı Palace after six years of confinement. Architecture Ahmed III built water claps, fountain and park waterfalls. Ahmed, who built three libraries, one inside the Topkapı Palace, and one of the famous lines of his period. Ahmed was a master in the writings on plates. Some plates and inscriptions have survived. The “Basmala” at the Topkapi Palace apartment door with its plates in the Üsküdar Yeni Mosque are among them. Topkapı Palace and its buildings have been the subject of many researches and publications. Among these researches, many different scope studies are also noticed together with postgraduate theses. Consequently, they provide rich information about the palace, which provides a long list of highly qualified scientific articles and books, guides and brochures promoting the palace and museum. However, Topkapi Palace and its units still have aspects to be explored and details to be discussed. Among them Ahmed III library can also be counted. A library was built by Ahmed in 1724–25 to the right of the porch in front of the tomb. The structure, which has stone-brick alternate meshed walls, is square-shaped and covered with a flattened dome with an octagonal rim, which is provided with pendants. There are original pen works left in the pendants and dome of the library. Disasters In 1714, an Egyptian galleon standing near the Gümrük (Eminönü) Pier caught fire and burned, and two hundred people died. Fire of 1718 While Nevşehirli Damat Ibrahim Pasha continued his preparations for return to Istanbul, a fire broke out in Istanbul. Unkapanı, Azapkapı, Zeyrek, Fatih, Saraçhane, Horhor, Etmeydanı, Molla Gürani, Altımermer, Ayazma Gate, Kantarcılar, Vefa, Vez Neciler, Old Rooms, Acemioğlanlar Barracks, Çukur Çeşme, Langa, Davudpaşa districts were burned from the fire. Earthquake of 1719 However, this festivity went astringent as it came just after the three-minute big earthquake on 14 May 1719. While the city walls of Istanbul were destroyed in the earthquake, 4000 people died in Izmit and Yalova was destroyed. After the earthquake, reconstruction work started in Istanbul. The most meaningful element that reflects the cultural aspect or weight of these works until today is the Topkapı Palace Enderun Library, which was built that year. A rich foundation was established for this institution, which is also known as Sultan Ahmed-i Salis Library, which has a face-to-face with its architectural and valuable manuscripts. Family Ahmed III is known to be the Sultan with the largest family of the Ottoman dynasty. The hostess of his harem was Dilhayat Kalfa, known to be one of the greatest Turkish composeress of the early modern period. Consorts Ahmed III had at least twenty-one consorts: Emetullah Kadın.

In fiction In Voltaire's Candide, the eponymous main character meets the deposed Ahmed III on a ship from Venice to Constantinople. The Sultan is in the company of five other deposed European monarchs, and he tells Candide, who initially doubts his credentials: I am not jesting, my name is Achmet III. For several years I was Sultan; I dethroned my brother; my nephew dethroned me; they cut off the heads of my viziers; I am ending my days in the old seraglio; my nephew, Sultan Mahmoud, sometimes allows me to travel for my health, and I have come to spend the Carnival at Venice." This episode was taken up by the modern Turkish writer Nedim Gürsel as the setting of his 2001 novel Le voyage de Candide à Istanbul. In fact, there is no evidence of the deposed Sultan being allowed to make such foreign travels, nor did Voltaire (or Gürsel) assert that it had any actual historical foundation.

Acropolis

An acropolis was the settlement of an upper part of an ancient Greek city, especially a citadel, and frequently a hill with precipitous sides, mainly chosen for purposes of defense. The term is typically used to refer to the Acropolis of Athens, yet every Greek city had an acropolis of its own. Acropoloi were used as religious centers and places of worship, forts, and places in which the royal and high-status resided. Acropolises became the nuclei of large cities of classical ancient times, and served as important centers of a community. Some well-known acropoloi have become the centers of tourism in present-day, and, especially, the Acropolis of Athens has been a revolutionary center for the studies of ancient Greece since the Mycenaean period. Many of them have become a source of revenue for Greece, and represent some great technology during the period. Origin An acropolis is defined by the Greek definition of , ; from () or () meaning “highest; edge; extremity”, and () meaning “city.” The plural of () is , also commonly as and , and in Greek. This word was first used in the 14th century BCE, in the context of Mycenaean kings and community. The term acropolis is also used to describe the central complex of overlapping structures, such as plazas and pyramids, in many Maya cities, including Tikal and Copán. Acropolis is also the term used by archaeologists and historians for the urban Castro culture settlements located in Northwestern Iberian hilltops. It is primarily associated with the Greek cities of Athens, Argos (with Larisa), Thebes (with Cadmea), Corinth (with its Acrocorinth), and Rhodes (with its Acropolis of Lindos). It may also be applied generically to all such citadels including Rome, Carthage, Jerusalem, Celtic Bratislava, Asia Minor, or Castle Rock in Edinburgh. An example in Ireland is the Rock of Cashel. In Central Italy, many small rural communes still cluster at the base of a fortified habitation known as of the commune. Other parts of the world have developed other names for the high citadel, or , which often have reinforced a naturally strong site. Because of this, many cultures have included acropolises in their societies, however, do not use the same name for them. Differing acropoleis The acropolis of a city was used in many ways, with regards to ancient time and through references. Because an acropolis was built at the highest part of a city, it served as a highly functional form of protection—a fortress—as well as being a home to the royal of a city, and a center for religion through the worshipping of different gods. There have been many classical and ancient acropolises, including the most commonly-known, Acropolis of Athens, as well as the Tepecik Acropolis at Patara, Ankara Acropolis, Acropolis of La Blanca, Acropolis at the Maya Site in Guatemala, and the Acropolis at Halieis. The most famous example is the Athenian Acropolis, which is a collection of structures featuring a citadel on the highest part of land in ancient (and modern-day) Athens, Greece. Many notable structures at this site were constructed in the 5th century BCE, including the Propylaea, Erechtheion, and the Temple of Athena. The Temple is also commonly known as the Parthenon, which is derived from the divine Athena Parthenos. There were often dances, music, and plays held at this acropolis, and it served as a community center for the city of Athens. This acropolis became a prime tourist destination by the second century AD during the Roman Empire, and was known as "the Greece of Greece," as coined by an unknown poet. Although originating in the mainland of Greece, use of this acropolis model quickly spread to Greek colonies such as the Dorian Lato on Crete during the Archaic Period. The Tepecik Acropolis at Patara served as a harbor to nearby communities and naval forces, such as Antigonos I Monopthalmos and Demetrios Poliorketes, and combined land and sea. Its fortification wall and Bastion date back to the Classical period. The acropolis was constructed in the fourth century BCE by the Hekatomnids that ultimately led to its seizure in 334 BCE by Alexander the Great. The acropolis contributed significantly to the overall development that took place during the Hellenistic empires. This acropolis was the earliest place of settlement, probably dating back to the third millennium BCE. During excavations that took place in 1989, ceramic items, terracotta figurines, coins, bone and stone objects were found that date to the fourth century BCE. The fortification wall and bastion that are built at this acropolis uses a style of masonry, commonly known as the Greek word (meaning "woven"). This style of masonry was likely used for weight-bearing purposes. The Acropolis at Halieis dates back to the Neolithic and Classical periods. It included a fortified wall, sanctuary of Apollo (two temples, an altar, a race course), and necropolis (cemetery). This acropolis was the highest point of fortification on the south edge at Halieis. There was a small open-air cult space, including an altar and monuments. The Ankara Acropolis, which was set in modern-day Turkey, is a historically prominent space that has changed over time through the urban development of the country from the Phrygian period. This acropolis was well known as a spot for holy worshipping, and was symbolic of the time. It has also been a place that has historically recognized the legislative changes that Turkey has faced.   The Acropolis of La Blanca was created in Guatemala as a small, ancient Maya settlement and archaeological site that is located adjacent to the Salsipuedes River. This acropolis developed as a place of residence for the city of La Blanca's rulers. Its main period of usage was during the Classical period of 600 AD to 850 AD, as the city developed as a commercial place of trade among a number of nearby settlements. The Mayan Acropolis site in Guatemala included a burial site and vaulted tombs of the highest status royal. This funerary structure was integrated into this sacred landscape, and illustrated the prosperity of power between the royal figures of Pedras Negras in Guatemala. Modern-day uses Tourism Acropolises today have become the epicenters of tourism and attraction sites in many modern-day Greek cities. The Athenian Acropolis, in particular, is the most famous, and has the best vantage point in Athens, Greece. Today, tourists can purchase tickets to visit the Athenian Acropolis, including walking, sightseeing, and bus tours, as well as a classic Greek dinner. Cultural ties Because of its classical Hellenistic and Greco-Roman style, the ruins of Mission San Juan Capistrano's Great Stone Church in California, United States has been called an American Acropolis. The civilization developed its religious, educational, and cultural aspects of the acropolis, and is used today as a location that holds events, such as operas. The neighborhood of Morningside Heights in New York City is commonly referred to as the "Academic Acropolis" due to its high elevation and the concentration of educational institutions in the area, including Columbia University and its affiliates, Barnard College, Teachers College, Union Theological Seminary and the Jewish Theological Seminary of America; Manhattan School of Music; Bank Street College of Education; and New York Theological Seminary. The analogy is also aided by the neoclassical architecture of the Columbia University campus, which was designed by McKim, Mead & White in the early 20th century. Excavations Much of the modern-day uses of acropolises have been discovered through excavations that have developed over the course of many years. For example, the Athenian Acropolis includes a Great Temple that holds the Parthenon, a specific space for ancient worship. Through today's findings and research, the Parthenon treasury is able to be recognized as the west part of the structure (the Erechtheion), as well as the Parthenon itself. Most excavations have been able to provide archaeologists with samples of pottery, ceramics, and vessels. The excavation of the Acropolis of Halieis produced remains that provided context that dated the Acropolis at Halieis from the Final Neolithic period through the first Early Helladic period.

Amaranth

Amaranthus is a cosmopolitan genus of annual or short-lived perennial plants collectively known as amaranths. Some amaranth species are cultivated as leaf vegetables, pseudocereals, and ornamental plants. Catkin-like cymes of densely packed flowers grow in summer or autumn. Amaranth varies in flower, leaf, and stem color with a range of striking pigments from the spectrum of maroon to crimson and can grow longitudinally from tall with a cylindrical, succulent, fibrous stem that is hollow with grooves and bracteoles when mature. There are approximately 75 species in the genus, 10 of which are dioecious and native to North America with the remaining 65 monoecious species endemic to every continent (except Antarctica) from tropical lowlands to the Himalayas. Members of this genus share many characteristics and uses with members of the closely related genus Celosia. Amaranth grain is collected from the genus. The leaves of some species are also eaten. Description Amaranth is a herbaceous plant or shrub that is either annual or perennial across the genus. Flowers vary interspecifically from the presence of 3 or 5 tepals and stamens, whereas a 7-porate pollen grain structure remains consistent across the family. Species across the genus contain concentric rings of vascular bundles, and fix carbon efficiently with a C4 photosynthetic pathway. Leaves are approximately and of oval or elliptical shape that are either opposite or alternate across species, although most leaves are whole and simple with entire margins. Amaranth has a primary root with deeper spreading secondary fibrous root structures. Inflorescences are in the form a large panicle that varies from terminal to axial, color, and sex. The tassel of fluorescence is either erect or bent and varies in width and length between species. Flowers are radially symmetric and either bisexual or unisexual with very small, bristly perianth and pointy bracts. Species in this genus are either monecious (e.g. A. hybridus,) or dioecious (e.g. A. palmeri). Fruits are in the form of capsules referred to as a unilocular pixdio that opens at maturity. The top (operculum) of the unilocular pixdio releases the urn that contains the seed. Seeds are circular form from 1 to 1.5 millimeters in diameter and range in color with a shiny, smooth seed coat. The panicle is harvested 200 days after cultivation with approximately 1,000 to 3,000 seeds harvested per gram. Chemistry Amaranth grain contains phytochemicals that are not defined as nutrients and may be antinutrient factors, such as polyphenols, saponins, tannins, and oxalates. These compounds are reduced in content and antinutrient effect by cooking. Taxonomy Amaranthus shows a wide variety of morphological diversity among and even within certain species. Amaranthus is part of the Amaranthaceae that is part of the larger grouping of the Carophyllales. Although the family (Amaranthaceae) is distinctive, the genus has few distinguishing characters among the 75 species present across six continents. This complicates taxonomy and Amaranthus has generally been considered among systematists as a "difficult" genus and to hybridize often. In 1955, Sauer classified the genus into two subgenera, differentiating only between monoecious and dioecious species: Acnida (L.) Aellen ex K.R. Robertson and Amaranthus. Although this classification was widely accepted, further infrageneric classification was (and still is) needed to differentiate this widely diverse group. Mosyakin and Robertson 1996 later divided into three subgenera: Acnida, Amaranthus, and Albersia. The support for the addition of the subdivision Albersia because of its indehiscent fruits coupled with three elliptic to linear tepals to be exclusive characters to members of this subgenus. The classification of these groups are further supported with a combination of floral characters, reproductive strategies, geographic distribution, and molecular evidence. The phylogenies of Amaranthus using maximum parsimony and Bayesian analysis of nuclear and chloroplast genes suggest five clades within the genus: Diecious / Pumilus, Hybris, Galapagos, Eurasian/ South African, Australian (ESA), ESA + South American. Amaranthus includes three recognised subgenera and 75 species, although species numbers are questionable due to hybridisation and species concepts. Infrageneric classification focuses on inflorescence, flower characters and whether a species is monoecious/dioecious, as in the Sauer (1955) suggested classification. Bracteole morphology present on the stem is used for taxonomic classification of Amaranth. Wild species have longer bracteoles compared to cultivated species. A modified infrageneric classification of Amaranthus includes three subgenera: Acnida, Amaranthus, and Albersia, with the taxonomy further differentiated by sections within each of the subgenera. There is near certainty that A. hypochondriacus is the common ancestor to the cultivated grain species, however the later series of domestication to follow remains unclear. There has been opposing hypotheses of a single as opposed to multiple domestication events of the three grain species. There is evidence of phylogenetic and geographical support for clear groupings that indicate separate domestication events in South America and Central America. A. hybridus may derive from South America, whereas A. caudatus, A. hypochondriacus, and A. quentiensis are native to Central and North America. Species Species include: Amaranthus acanthochiton – greenstripe Amaranthus acutilobus – a synonym of Amaranthus viridis Amaranthus albus – white pigweed, tumble pigweed Amaranthus anderssonii Amaranthus arenicola – sandhill amaranth Amaranthus australis – southern amaranth Amaranthus bigelovii – Bigelow's amaranth Amaranthus blitoides – mat amaranth, prostrate amaranth, prostrate pigweed Amaranthus blitum – purple amaranth Amaranthus brownii – Brown's amaranth Amaranthus californicus – California amaranth, California pigweed Amaranthus cannabinus – tidal-marsh amaranth Amaranthus caudatus – love-lies-bleeding, pendant amaranth, tassel flower, quilete Amaranthus chihuahuensis – Chihuahuan amaranth Amaranthus crassipes – spreading amaranth Amaranthus crispus – crispleaf amaranth Amaranthus cruentus – purple amaranth, red amaranth, Mexican grain amaranth Amaranthus deflexus – large-fruit amaranth Amaranthus dubius – spleen amaranth, khada sag Amaranthus fimbriatus – fringed amaranth, fringed pigweed Amaranthus floridanus – Florida amaranth Amaranthus furcatus Amaranthus graecizans Amaranthus grandiflorus Amaranthus greggii – Gregg's amaranth Amaranthus hybridus – smooth amaranth, smooth pigweed, red amaranth Amaranthus hypochondriacus – Prince-of-Wales feather, prince's feather Amaranthus interruptus – Australian amaranth Amaranthus minimus Amaranthus mitchellii Amaranthus muricatus – African amaranth Amaranthus obcordatus – Trans-Pecos amaranth Amaranthus palmeri – Palmer's amaranth, Palmer pigweed, careless weed Amaranthus polygonoides – tropical amaranth Amaranthus powellii – green amaranth, Powell amaranth, Powell pigweed Amaranthus pringlei – Pringle's amaranth Amaranthus pumilus – seaside amaranth Amaranthus quitensis - Mucronate Amaranth Amaranthus retroflexus – red-root amaranth, redroot pigweed, common amaranth Amaranthus saradhiana Amaranthus scleranthoides – variously Amaranthus sclerantoides Amaranthus scleropoides – bone-bract amaranth Amaranthus spinosus – spiny amaranth, prickly amaranth, thorny amaranth Amaranthus standleyanus Amaranthus thunbergii – Thunberg's amaranth Amaranthus torreyi – Torrey's amaranth Amaranthus tricolor – Joseph's-coat Amaranthus tuberculatus – rough-fruit amaranth, tall waterhemp Amaranthus viridis – slender amaranth, green amaranth Amaranthus watsonii – Watson's amaranth Amaranthus wrightii – Wright's amaranth Etymology "Amaranth" derives from Greek (), "unfading", with the Greek word for "flower", (), factoring into the word's development as amaranth, the unfading flower. Amarant is an archaic variant. The name was first applied to the related Celosia (Amaranthus and Celosia share long-lasting dried flowers), as Amaranthus plants were not yet known in Europe. Ecology Amaranth weed species have an extended period of germination, rapid growth, and high rates of seed production, and have been causing problems for farmers since the mid-1990s. This is partially due to the reduction in tillage, reduction in herbicidal use and the evolution of herbicidal resistance in several species where herbicides have been applied more often. The following 9 species of Amaranthus are considered invasive and noxious weeds in the U.S and Canada: A. albus, A. blitoides, A. hybridus, A. palmeri, A. powellii, A. retroflexus, A. spinosus, A. tuberculatus, and A. viridis. A new herbicide-resistant strain of A. palmeri has appeared; it is glyphosate-resistant and so cannot be killed by herbicides using the chemical. Also, this plant can survive in tough conditions. The species Amaranthus palmeri (Palmer amaranth) causes the greatest reduction in soybean yields and has the potential to reduce yields by 17-68% in field experiments. Palmer amaranth is among the "top five most troublesome weeds" in the southeast of the United States and has already evolved resistances to dinitroaniline herbicides and acetolactate synthase inhibitors. This makes the proper identification of Amaranthus species at the seedling stage essential for agriculturalists. Proper weed control needs to be applied before the species successfully colonizes in the crop field and causes significant yield reductions. An evolutionary lineage of around 90 species within the genus has acquired the carbon fixation pathway, which increases their photosynthetic efficiency. This probably occurred in the Miocene. Uses All parts of the plant are considered edible, though some may have sharp spines that need to be removed before consumption. Nutrition Uncooked amaranth grain by weight is 12% water, 65% carbohydrates (including 7% dietary fiber), 14% protein, and 7% fat (table). A reference serving of uncooked amaranth grain provides of food energy, and is a rich source (20% or more of the Daily Value, DV) of protein, dietary fiber, pantothenic acid, vitamin B6, folate, and several dietary minerals (table). Uncooked amaranth is particularly rich in manganese (159% DV), phosphorus (80% DV), magnesium (70% DV), iron (59% DV), and selenium (34% DV). Cooking decreases its nutritional value substantially across all nutrients, with only dietary minerals remaining at moderate levels. Cooked amaranth leaves are a rich source of vitamin A, vitamin C, calcium, and manganese, with moderate levels of folate, iron, magnesium, and potassium. Amaranth does not contain gluten. History The native range of the genus is cosmopolitan. In pre-Hispanic times, amaranth was cultivated by the Aztec and their tributary communities in a quantity very similar to maize. Known to the Aztecs as , amaranth is thought to have represented up to 80% of their energy consumption before the Spanish conquest. Another important use of amaranth throughout Mesoamerica was in ritual drinks and foods. To this day, amaranth grains are toasted much like popcorn and mixed with honey, molasses, or chocolate to make a treat called , meaning "joy" in Spanish. While all species are believed to be native to the New World, several have been cultivated and introduced to warm regions worldwide. Amaranth's cosmopolitan distribution makes it one of many plants providing evidence of pre-Columbian oceanic contact. The earliest archeological evidence for amaranth in the Old World was found in an excavation in Narhan, India, dated to 1000–800 BCE. Because of its importance as a symbol of indigenous culture, its palatability, ease of cooking, and a protein that is particularly well-suited to human nutritional needs, interest in amaranth seeds (especially A. cruentus and A. hypochondriacus) revived in the 1970s. It was recovered in Mexico from wild varieties and is now commercially cultivated. It is a popular snack in Mexico, sometimes mixed with chocolate or puffed rice, and its use has spread to Europe and other parts of North America. Seed Several species are raised for amaranth "grain" in Asia and the Americas. Amaranth and its relative quinoa are considered pseudocereals because of their similarities to cereals in flavor and cooking. The spread of Amaranthus is of a joint effort of human expansion, adaptation, and fertilization strategies. Grain amaranth has been used for food by humans in several ways. The grain can be ground into a flour for use like other grain flours. It can be popped like popcorn, or flaked like oatmeal. Seeds of Amaranth grain have been found in Antofagasta de la Sierra Department, Catamarca, Argentina in the southern Puna desert of the north of Argentina dating from 4,500 years ago, with evidence suggesting earlier use. Archeological evidence of seeds from A. hypochondriacus and A. crutenus found in a cave in Tehuacán, Mexico, suggests amaranth was part of Aztec civilization in the 1400s. Ancient amaranth grains still used include the three species Amaranthus caudatus, A. cruentus, and A. hypochondriacus. Evidence from single-nucleotide polymorphisms and chromosome structure supports A. hypochondriacus as the common ancestor of the three grain species. It has been proposed as an inexpensive native crop that could be cultivated by indigenous people in rural areas for several reasons: A small amount of seed plants a large area (seeding rate 1 kg/ha). Yields are high compared to the seeding rate: 1,000 kg or more per hectare. It is easily harvested and easily processed, post harvest, as there are no hulls to remove. Its seeds are a source of protein. It has rich content of the dietary minerals, calcium, magnesium, phosphorus, and potassium. In cooked and edible forms, amaranth retains adequate content of several dietary minerals. It is easy to cook. Boil in water with twice the amount of water as grain by volume (or 2.4 times as much water by weight). Amaranth seed can also be popped one tablespoon at a time in a hot pan without oil, shaken every few seconds to avoid burning. It grows fast and, in three cultivated species, the large seedheads can weigh up to 1 kg and contain a half-million small seeds. In the United States, the amaranth crop is mostly used for seed production. Most amaranth in American food products starts as a ground flour, blended with wheat or other flours to create cereals, crackers, cookies, bread or other baked products. Despite utilization studies showing that amaranth can be blended with other flours at levels above 50% without affecting functional properties or taste, most commercial products use amaranth only as a minor portion of their ingredients despite them being marketed as "amaranth" products. Leaves, roots, and stems Amaranth species are cultivated and consumed as a leaf vegetable in many parts of the world. Four species of Amaranthus are documented as cultivated vegetables in eastern Asia: Amaranthus cruentus, Amaranthus blitum, Amaranthus dubius, and Amaranthus tricolor. Asia In Indonesia and Malaysia, leaf amaranth is called (although the word has since been loaned to refer to spinach, in a different genus). In the Philippines, the Ilocano word for the plant is ; the Tagalog word for the plant is or . In Uttar Pradesh and Bihar in India, it is called and is a popular red leafy vegetable (referred to in the class of vegetable preparations called ). It is called chua in Kumaun area of Uttarakhand, where it is a popular red-green vegetable. In Karnataka in India, it is called () . It is used to prepare curries such as hulee, palya, majjigay-hulee, and so on. In Kerala, it is called cheera and is consumed by stir-frying the leaves with spices and red chili peppers to make a dish called cheera thoran. In Tamil Nadu, it is called and is regularly consumed as a favourite dish, where the greens are steamed and mashed with light seasoning of salt, red chili pepper, and cumin. It is called . In the states of Andhra Pradesh and Telangana and other Telugu speaking regions of the country, this leaf is called as "Thotakura" and is cooked as a standalone curry, added as a part of mix leafy vegetable curry or added in preparation of a popular dal called in (Telugu). In Maharashtra, it is called and is available in both red and white colour. In Orissa, it is called , it is used to prepare , in which the leaf is fried with chili and onions. In West Bengal, the green variant is called () and the red variant is called (). In China, the leaves and stems are used as a stir-fry vegetable, or in soups. In Vietnam, it is called and is used to make soup. Two species are popular as edible vegetable in Vietnam: (Amaranthus tricolor) and or (Amaranthus viridis). Africa A traditional food plant in Africa, amaranth has the potential to improve nutrition, boost food security, foster rural development and support sustainable land care. In Bantu regions of Uganda and western Kenya, it is known as doodo or litoto. It is also known among the Kalenjin as a drought crop (chepkerta). In Lingala (spoken in the Congo), it is known as or . In Nigeria, it is a common vegetable and goes with all Nigerian starch dishes. It is known in Yoruba as , a short form of (meaning "make the husband fat"), or (meaning "we have money left over for fish"). In Botswana, it is referred to as morug and cooked as a staple green vegetable. Europe In Greece, purple amaranth (Amaranthus Blitum) is a popular dish called , or . It is boiled, then served with olive oil and lemon juice like a salad, sometimes alongside fried fish. Greeks stop harvesting the plant (which also grows wild) when it starts to bloom at the end of August. Americas In Brazil, green amaranth was, and to a degree still is, often considered an invasive species as all other species of amaranth (except the generally imported A. caudatus cultivar), though some have traditionally appreciated it as a leaf vegetable, under the names of or , which is consumed cooked, generally accompanying the staple food, rice and beans. In the Caribbean, the leaves are called bhaji in Trinidad and callaloo in Jamaica, and are sautéed with onions, garlic, and tomatoes, or sometimes used in a soup called pepperpot soup. Oil Making up about 5% of the total fatty acids of amaranth, squalene is extracted as a vegetable-based alternative to the more expensive shark oil for use in dietary supplements and cosmetics. Dyes The flowers of the 'Hopi Red Dye' amaranth were used by the Hopi (a tribe in the western United States) as the source of a deep red dye. Also a synthetic dye was named "amaranth" for its similarity in color to the natural amaranth pigments known as betalains. This synthetic dye is also known as Red No. 2 in North America and E123 in the European Union. Ornamentals The genus also contains several well-known ornamental plants, such as Amaranthus caudatus (love-lies-bleeding), a vigorous, hardy annual with dark purplish flowers crowded in handsome drooping spikes. Another Indian annual, A. hypochondriacus (prince's feather), has deeply veined, lance-shaped leaves, purple on the under face, and deep crimson flowers densely packed on erect spikes. Amaranths are recorded as food plants for some Lepidoptera (butterfly and moth) species including the nutmeg moth and various case-bearer moths of the genus Coleophora: C. amaranthella, C. enchorda (feeds exclusively on Amaranthus), C. immortalis (feeds exclusively on Amaranthus), C. lineapulvella, and C. versurella (recorded on A. spinosus). Culture Diego Durán described the festivities for the Aztec god . The Aztec month of (7 December to 26 December) was dedicated to . People decorated their homes and trees with paper flags; ritual races, processions, dances, songs, prayers, and finally human sacrifices were held. This was one of the more important Aztec festivals, and the people prepared for the whole month. They fasted or ate very little; a statue of the god was made out of amaranth seeds and honey, and at the end of the month, it was cut into small pieces so everybody could eat a piece of the god. After the Spanish conquest, cultivation of amaranth was outlawed, while some of the festivities were subsumed into the Christmas celebration. Amaranth is associated with longevity and, poetically, with death and immortality. Amaranth garlands were used in the mourning of Achilles. John Milton's Paradise Lost portrays a showy amaranth in the Garden of Eden, "remov'd from Heav'n" when it blossoms because the flowers "shade the fountain of life". He describes amaranth as "immortal" in reference to the flowers that generally do not wither and retain bright reddish tones of color, even when deceased; referred to in one species as "love-lies-bleeding."

Agathon

Agathon (; ; ) was an Athenian tragic poet whose works have been lost. He is best known for his appearance in Plato's Symposium, which describes the banquet given to celebrate his obtaining a prize for his first tragedy at the Lenaia in 416. He is also a prominent character in Aristophanes' comedy the Thesmophoriazusae. Life and career Agathon was the son of Tisamenus, and the lover of Pausanias, with whom he appears in both the Symposium and Plato's Protagoras. Together with Pausanias, he later moved to the court of Archelaus, king of Macedon, who was recruiting playwrights; it is here that he probably died around 401 BC. Agathon introduced certain innovations into the Greek theater: Aristotle tells us in the Poetics (1456a) that the characters and plot of his Anthos were original and not, following Athenian dramatic orthodoxy, borrowed from mythological or historical subjects. Agathon was also the first playwright to write choral parts which were apparently independent from the main plot of his plays. Agathon is portrayed by Plato as a handsome young man, well dressed, of polished manners, courted by the fashion, wealth and wisdom of Athens, and dispensing hospitality with ease and refinement. The epideictic speech in praise of love which Agathon recites in the Symposium is full of beautiful but artificial rhetorical expressions, and has led some scholars to believe he may have been a student of Gorgias. In the Symposium, Agathon is presented as the friend of the comic poet Aristophanes, but this alleged friendship did not prevent Aristophanes from harshly criticizing Agathon in at least two of his comic plays: the Thesmophoriazousae and the (now lost) Gerytades. In the later play Frogs, Aristophanes softens his criticisms, but even so it may be only for the sake of punning on Agathon's name (ἁγαθός "good") that he makes Dionysus call him a "good poet". Agathon was also a friend of Euripides, another recruit to the court of Archelaus of Macedon. Physical appearance Agathon's extraordinary physical beauty is brought up repeatedly in the sources; the historian W. Rhys Roberts observes that "ὁ καλός Ἀγάθων (ho kalos Agathon) has become almost a stereotyped phrase." The most detailed surviving description of Agathon is in the Thesmophoriazousae, in which Agathon appears as a pale, clean-shaven young man dressed in women's clothes. Scholars are unsure how much of Aristophanes' portrayal is fact and how much mere comic invention. After a close reading of the Thesmophoriazousae, the historian Jane McIntosh Snyder observed that Agathon's costume was almost identical to that of the famous lyric poet Anacreon, as he is portrayed in early 5th-century vase-paintings. Snyder theorizes that Agathon might have made a deliberate effort to mimic the sumptuous attire of his famous fellow-poet, although by Agathon's time, such clothing, especially the κεκρύφαλος (kekryphalos, an elaborate covering for the hair) had long fallen out of fashion for men. According to this interpretation, Agathon is mocked in the Thesmophoriazousae not only for his notorious effeminacy, but also for the pretentiousness of his dress: "he seems to think of himself, in all his elegant finery, as a rival to the old Ionian poets, perhaps even to Anacreon himself." Plato's epigram Agathon has been thought to be the subject of Lovers' Lips, an epigram attributed to Plato: Kissing Agathon, I had my soul upon my lips; for it rose, poor wretch, as though to cross over. Another translation reads: Kissing Agathon, I found my soul at my lips. Poor thing! It went there, hoping--to slip across. Although the authenticity of this epigram was accepted for many centuries, it was probably not composed for Agathon the tragedian, nor was it composed by Plato. Stylistic evidence suggests that the poem (with most of Plato's other alleged epigrams) was actually written some time after Plato had died: its form is that of the Hellenistic erotic epigram, which did not become popular until after 300 BC. According to 20th-century scholar Walther Ludwig, the poems were spuriously inserted into an early biography of Plato sometime between 250 BC and 100 BC and adopted by later writers from this source. Known plays Of Agathon's plays, only six titles and thirty-one fragments have survived: Aerope Alcmeon Anthos or Antheus ("The Flower") Mysoi ("Mysians") Telephos ("Telephus") Thyestes Fragments in A Nauck, Tragicorum graecorum fragmenta (1887).

Arthur Aikin

Arthur Aikin (19 May 177315 April 1854) was an English chemist, mineralogist and scientific writer, and was a founding member of the Chemical Society (now the Royal Society of Chemistry). He first became its treasurer in 1841, and later became the society's second president. Life He was born at Warrington, Lancashire into a distinguished literary family of prominent Unitarians. The best known of these was his paternal aunt, Anna Laetitia Barbauld, a woman of letters who wrote poetry and essays as well as early children's literature. His father, Dr John Aikin, was a medical doctor, historian, and author. His grandfather, also called John (1713–1780), was a Unitarian scholar and theological tutor, closely associated with Warrington Academy. His sister Lucy (1781–1864) was a historical writer. Their brother Charles Rochemont Aikin was adopted by their famous aunt and brought up as their cousin. Arthur Aikin studied chemistry under Joseph Priestley in the New College at Hackney, and gave attention to the practical applications of the science. In early life, he was a Unitarian minister for a short time. Aikin lectured on chemistry at Guy's Hospital for thirty-two years. He became the President of the British Mineralogical Society in 1801 for five years up until 1806 when the Society merged with the Askesian Society. From 1803 to 1808 he was editor of the Annual Review. In 1805 Aiken also became a proprietor of the London Institution, which was officially founded in 1806. He was one of the founders of the Geological Society of London in 1807 and was its honorary secretary in 1812–1817. He also gave lectures in 1813 and 1814. He contributed papers on the Wrekin and the Shropshire coalfield, among others, to the transactions of that society. His Manual of Mineralogy was published in 1814.

He was founder of the Chemical Society of London in 1841, being its first treasurer and, between 1843 and 1845, second president. In order to support himself, outside of his work with the British Mineralogical Society, the London Institution and the Geological Society, Aiken worked as a writer, translator and lecturer to the public and to medical students at Guy's Hospital. His writing and journalism were useful for publicising foreign scientific news to the wider British public.
