Near-infrared is the region closest in wavelength to the radiation detectable by the human eye, mid- and far-infrared are progressively further from the visible spectrum. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (the common silicon detectors are sensitive to about 1,050 nm, while InGaAs's sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately, international standards for these specifications are not currently available.

Between the 8th and 18th centuries, the use of glazed ceramics was prevalent in Islamic art, usually assuming the form of elaborate pottery. Tin-opacified glazing was one of the earliest new technologies developed by the Islamic potters. The first Islamic opaque glazes can be found as blue-painted ware in Basra, dating to around the 8th century. Another contribution was the development of stone-paste ceramics, originating from 9th century Iraq. Other centers for innovative ceramic pottery in the Old world included Fustat (from 975 to 1075), Damascus (from 1100 to around 1600) and Tabriz (from 1470 to 1550).

Impermanence (Pāli: anicca) expresses the Buddhist notion that all compounded or conditioned phenomena (all things and experiences) are inconstant, unsteady, and impermanent. Everything we can experience through our senses is made up of parts, and its existence is dependent on external conditions. Everything is in constant flux, and so conditions and the thing itself are constantly changing. Things are constantly coming into being, and ceasing to be. Since nothing lasts, there is no inherent or fixed nature to any object or experience. According to the doctrine of impermanence, life embodies this flux in the aging process, the cycle of rebirth (saṃsāra), and in any experience of loss. The doctrine asserts that because things are impermanent, attachment to them is futile and leads to suffering (dukkha).

The people of Somerset are mentioned in the Anglo-Saxon Chronicle's entry for AD 845, in the inflected form "Sumursætum", and the county is recorded in the entry for 1015 using the same name. The archaic name Somersetshire was mentioned in the Chronicle's entry for 878. Although "Somersetshire" was in common use as an alternative name for the county, it went out of fashion in the late 19th century, and is no longer used possibly due to the adoption of "Somerset" as the county's official name after the establishment of the county council in 1889. As with other counties not ending in "shire," the suffix was superfluous, as there was no need to differentiate between the county and a town within it.

Ripple current is the AC component of an applied source (often a switched-mode power supply) whose frequency may be constant or varying. Ripple current causes heat to be generated within the capacitor due to the dielectric losses caused by the changing field strength together with the current flow across the slightly resistive supply lines or the electrolyte in the capacitor. The equivalent series resistance (ESR) is the amount of internal series resistance one would add to a perfect capacitor to model this. Some types of capacitors, primarily tantalum and aluminum electrolytic capacitors, as well as some film capacitors have a specified rating value for maximum ripple current.

---

Question: What is one type of capacitor that has a specified rating value for maximum ripple current?
Answer: aluminum electrolytic capacitors.

Downtown Oklahoma City, which has 7,600 residents, is currently seeing an influx of new private investment and large scale public works projects, which have helped to resuscitate a central business district left almost deserted by the Oil Bust of the early 1980s. The centerpiece of downtown is the newly renovated Crystal Bridge and Myriad Botanical Gardens, one of the few elements of the Pei Plan to be completed. In the next few years a massive new central park will link the gardens near the CBD and the new convention center to be built just south of it to the North Canadian River, as part of a massive works project known as Core to Shore; the new park is part of MAPS3, a collection of civic projects funded by a 1-cent temporary (seven-year) sales tax increase.

Wood has been an important construction material since humans began building shelters, houses and boats. Nearly all boats were made out of wood until the late 19th century, and wood remains in common use today in boat construction. Elm in particular was used for this purpose as it resisted decay as long as it was kept wet (it also served for water pipe before the advent of more modern plumbing).

The principle of the modern computer was first described by mathematician and pioneering computer scientist Alan Turing, who set out the idea in his seminal 1936 paper, On Computable Numbers. Turing reformulated Kurt Gödel's 1931 results on the limits of proof and computation, replacing Gödel's universal arithmetic-based formal language with the formal and simple hypothetical devices that became known as Turing machines. He proved that some such machine would be capable of performing any conceivable mathematical computation if it were representable as an algorithm. He went on to prove that there was no solution to the Entscheidungsproblem by first showing that the halting problem for Turing machines is undecidable: in general, it is not possible to decide algorithmically whether a given Turing machine will ever halt.

In 1238, King James I of Aragon, with an army composed of Aragonese, Catalans, Navarrese and crusaders from the Order of Calatrava, laid siege to Valencia and on 28 September obtained a surrender. Fifty thousand Moors were forced to leave. Poets such as Ibn al-Abbar and Ibn Amira mourned this exile from their beloved Valencia. After the Christian victory and the expulsion of the Muslim population the city was divided between those who had participated in the conquest, according to the testimony in the Llibre del Repartiment (Book of Distribution). James I granted the city new charters of law, the Furs of Valencia, which later were extended to the whole kingdom of Valencia. Thenceforth the city entered a new historical stage in which a new society and a new language developed, forming the basis of the character of the Valencian people as they are known today.

Some Estonians, unwilling to side directly with the Nazis, joined the Finnish Army (which was allied with the Nazis) to fight against the Soviet Union. The Finnish Infantry Regiment 200 (Estonian: soomepoisid) was formed out of Estonian volunteers in Finland. Although many Estonians were recruited into the German armed forces (including Estonian Waffen-SS), the majority of them did so only in 1944 when the threat of a new invasion of Estonia by the Red Army had become imminent. In January 1944 Estonia was again facing the prospect of invasion from the Red Army and the last legitimate prime minister of the Republic of Estonia (according to the Constitution of the Republic of Estonia) delivered a radio address asking all able-bodied men born from 1904 through 1923 to report for military service. The call resulted in around 38,000 new enlistments and several thousand Estonians who had joined the Finnish Army came back to join the newly formed Territorial Defense Force, assigned to defend Estonia against the Soviet advance. It was hoped[by whom?] that by engaging in such a war Estonia would be able to attract Western support for Estonian independence.

The Age of Enlightenment was a European affair. The 17th century "Age of Reason" opened the avenues to the decisive steps towards modern science, which took place during the 18th century "Age of Enlightenment". Directly based on the works of Newton, Descartes, Pascal and Leibniz, the way was now clear to the development of modern mathematics, physics and technology by the generation of Benjamin Franklin (1706–1790), Leonhard Euler (1707–1783), Mikhail Lomonosov (1711–1765) and Jean le Rond d'Alembert (1717–1783), epitomized in the appearance of Denis Diderot's Encyclopédie between 1751 and 1772. The impact of this process was not limited to science and technology, but affected philosophy (Immanuel Kant, David Hume), religion (the increasingly significant impact of science upon religion), and society and politics in general (Adam Smith, Voltaire), the French Revolution of 1789 setting a bloody cesura indicating the beginning of political modernity[citation needed]. The early modern period is seen as a flowering of the European Renaissance, in what is often known as the Scientific Revolution, viewed as a foundation of modern science.

The Legend of Zelda: Twilight Princess is an action-adventure game focused on combat, exploration, and item collection. It uses the basic control scheme introduced in Ocarina of Time, including context-sensitive action buttons and L-targeting (Z-targeting on the Wii), a system that allows the player to keep Link's view focused on an enemy or important object while moving and attacking. Link can walk, run, and attack, and will automatically jump when running off of or reaching for a ledge.[c] Link uses a sword and shield in combat, complemented with secondary weapons and items, including a bow and arrows, a boomerang, bombs, and the Clawshot (similar to the Hookshot introduced earlier in the The Legend of Zelda series).[d] While L-targeting, projectile-based weapons can be fired at a target without the need for manual aiming.[c]

Jidaigeki (literally historical drama) has always been a staple program on Japanese movies and television. The programs typically feature a samurai. Samurai films and westerns share a number of similarities and the two have influenced each other over the years. One of Japan’s most renowned directors, Akira Kurosawa, greatly influenced the samurai aspect in western film-making.[citation needed] George Lucas’ Star Wars series incorporated many aspects from the Seven Samurai film. One example is that in the Japanese film, seven samurai warriors are hired by local farmers to protect their land from being overrun by bandits; In George Lucas’ Star Wars: A New Hope, a similar situation arises. Kurosawa was inspired by the works of director John Ford and in turn Kurosawa's works have been remade into westerns such as The Seven Samurai into The Magnificent Seven and Yojimbo into A Fistful of Dollars. There is also a 26 episode anime adaptation (Samurai 7) of The Seven Samurai. Along with film, literature containing samurai influences are seen as well.

Comics are a medium used to express ideas by images, often combined with text or other visual information. Comics frequently takes the form of juxtaposed sequences of panels of images. Often textual devices such as speech balloons, captions, and onomatopoeia indicate dialogue, narration, sound effects, or other information. Size and arrangement of panels contribute to narrative pacing. Cartooning and similar forms of illustration are the most common image-making means in comics; fumetti is a form which uses photographic images. Common forms of comics include comic strips, editorial and gag cartoons, and comic books. Since the late 20th century, bound volumes such as graphic novels, comics albums, and tankōbon have become increasingly common, and online webcomics have proliferated in the 21st century.

Many of these species have adaptations to help in under-water locomotion. Water beetles and water bugs have legs adapted into paddle-like structures. Dragonfly naiads use jet propulsion, forcibly expelling water out of their rectal chamber. Some species like the water striders are capable of walking on the surface of water. They can do this because their claws are not at the tips of the legs as in most insects, but recessed in a special groove further up the leg; this prevents the claws from piercing the water's surface film. Other insects such as the Rove beetle Stenus are known to emit pygidial gland secretions that reduce surface tension making it possible for them to move on the surface of water by Marangoni propulsion (also known by the German term Entspannungsschwimmen).

In 1887, the British Empire celebrated Victoria's Golden Jubilee. Victoria marked the fiftieth anniversary of her accession on 20 June with a banquet to which 50 kings and princes were invited. The following day, she participated in a procession and attended a thanksgiving service in Westminster Abbey. By this time, Victoria was once again extremely popular. Two days later on 23 June, she engaged two Indian Muslims as waiters, one of whom was Abdul Karim. He was soon promoted to "Munshi": teaching her Hindustani, and acting as a clerk. Her family and retainers were appalled, and accused Abdul Karim of spying for the Muslim Patriotic League, and biasing the Queen against the Hindus. Equerry Frederick Ponsonby (the son of Sir Henry) discovered that the Munshi had lied about his parentage, and reported to Lord Elgin, Viceroy of India, "the Munshi occupies very much the same position as John Brown used to do." Victoria dismissed their complaints as racial prejudice. Abdul Karim remained in her service until he returned to India with a pension on her death.

In 1974, the unmanned AstroFlight Sunrise plane made the first solar flight. On 29 April 1979, the Solar Riser made the first flight in a solar-powered, fully controlled, man carrying flying machine, reaching an altitude of 40 feet (12 m). In 1980, the Gossamer Penguin made the first piloted flights powered solely by photovoltaics. This was quickly followed by the Solar Challenger which crossed the English Channel in July 1981. In 1990 Eric Scott Raymond in 21 hops flew from California to North Carolina using solar power. Developments then turned back to unmanned aerial vehicles (UAV) with the Pathfinder (1997) and subsequent designs, culminating in the Helios which set the altitude record for a non-rocket-propelled aircraft at 29,524 metres (96,864 ft) in 2001. The Zephyr, developed by BAE Systems, is the latest in a line of record-breaking solar aircraft, making a 54-hour flight in 2007, and month-long flights were envisioned by 2010. As of 2015, Solar Impulse, an electric aircraft, is currently circumnavigating the globe. It is a single-seat plane powered by solar cells and capable of taking off under its own power.

The changes brought about by these developments have led many scholars to view this period as the end of the Middle Ages and beginning of modern history and early modern Europe. However, the division is somewhat artificial, since ancient learning was never entirely absent from European society. As a result there was developmental continuity between the ancient age (via classical antiquity) and the modern age. Some historians, particularly in Italy, prefer not to speak of the late Middle Ages at all, but rather see the high period of the Middle Ages transitioning to the Renaissance and the modern era.

Question: What period do Italian historians believe came immediately after the High Period of the Middle Ages?
Answer: the Renaissance.

The value of the U.S. dollar declined significantly during wartime, especially during the American Civil War, World War I, and World War II. The Federal Reserve, which was established in 1913, was designed to furnish an "elastic" currency subject to "substantial changes of quantity over short periods", which differed significantly from previous forms of high-powered money such as gold, national bank notes, and silver coins. Over the very long run, the prior gold standard kept prices stable—for instance, the price level and the value of the U.S. dollar in 1914 was not very different from the price level in the 1880s. The Federal Reserve initially succeeded in maintaining the value of the U.S. dollar and price stability, reversing the inflation caused by the First World War and stabilizing the value of the dollar during the 1920s, before presiding over a 30% deflation in U.S. prices in the 1930s.
