A hypothesis is a proposed explanation for some event or problem. For a scientific hypothesis, the scientific method requires that one can test it. History. In the early 17th century, Cardinal Bellarmine gave a well known example of the older sense of the word in his warning to Galileo: that he must not treat the motion of the Earth as a reality, but merely as a hypothesis. Today, a hypothesis refers to an idea that needs to be tested. A hypothesis needs more work by the researcher in order to check it. A tested hypothesis that works may become part of a theory—or become a theory itself. The testing should be an attempt to prove that the hypothesis is wrong. That is, there should be a way to falsify the hypothesis, at least in principle if not in practice. People often call a hypothesis an "educated guess". "When it is not clear under which law of nature an effect or class of effect belongs, we try to fill this gap by means of a guess. Such guesses have been given the name "conjectures" or "hypotheses"". Hans Christian Ørsted (1811)  "In general we look for a new law by the following process. First we guess it. ..."  Experimenters may test and reject several hypotheses, before solving the problem or reaching a satisfactory theory. A 'working hypothesis' is just a rough kind of hypothesis that is provisionally accepted as a basis for further research. The hope is that a theory will be produced, even if the hypothesis ultimately fails. Hypotheses are especially important in science. Several philosophers have said that without hypotheses, there could be no science. In recent years, philosophers of science have tried to integrate the various approaches to testing hypotheses (and the scientific method in general), to form a more complete system. The point is that hypotheses are suggested ideas, which are then tested by experiments or observations. Statistics. In statistics, people talk about correlation: correlation is how closely related two events or phenomena are. A proposition (or hypothesis) that two events are related cannot be tested in the same way as a law of nature can be tested. An example would be to see if some drug is effective to treat a given
A city hall or town hall is the headquarters of a city or town's administration and usually houses the city or town council, its associated departments and their employees. It is also usually the base of the city, town, borough or county mayor.  In North America, a hall is labeled a "city" or "town" hall depending on the size of the municipality it serves. City halls are usually found in larger cities and town halls in smaller urban areas. In the United Kingdom, Australia, New Zealand, Hong Kong and many Commonwealth countries, "town hall" is the more common term. During the 1960s many of the older town halls were replaced by "Civic centres". The civic centre was a functional building, offices of the council only, without the art gallery or hall for cultural activities which were a feature of many of the older town halls. "County hall" is used for the headquarters of County council administrations.
A spectrometer is an optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. The independent variable is usually the wavelength of the light.  The variable measured is most often the light's intensity but could also, for instance, be the polarization state. A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities. Spectrometer is a term that is applied to instruments that operate over a very wide range of wavelengths, from gamma rays and X-rays into the far infrared. In general, any particular instrument will operate over a small portion of this total range because of the different techniques used to measure different portions of the spectrum. Below optical frequencies (that is, at microwave, radio, and audio frequencies), the spectrum analyzer is a closely related electronic device. Spectroscopes. Spectrometers are used in spectroscopic analysis to identify materials. Spectroscopes are used often in astronomy and some branches of chemistry. Early spectroscopes were simply a prism with graduations marking wavelengths of light. Modern spectroscopes, such as monochromators, generally use a diffraction grating, a movable slit, and some kind of photodetector, all automated and controlled by a computer. The spectroscope was invented by Gustav Robert Georg Kirchhoff and Robert Wilhelm Bunsen. 1882; Browning, John (1835-1925) NOT_IN_COPYRIGHT - online full-text download
Adenosine diphosphate (or ADP) is the chemical that plants make ATP from, during photosynthesis. A chemical compound that can be converted to ATP with the addition of one phosphate group.
Tefnut was the ancient Egyptian goddess of water and fertility. She and her brother and husband, Shu, were created by Atum, Ra or Amun. Tefnut was the mother of Nut and Geb also she is associated with the lion. In art she is represent as a woman with head of the lion with Sun disc. God's plan. Tefnut, along with Shu, were the first deities created by Ra. She had other names, such as Tefenet and Tefnet. She was mainly in charge of moisture, but was also responsible for Order, Time, Justice, Heaven and Hell. She was very closely related to both the sun and the moon. She was known as both the left (moon), and right (sun): 'Eyes of Ra.' Physical description. Once Tefnut fled from Ra as a lioness, causing a great drought. Only Thoth could persuade her to return, so he went to Nubia and got her back. When she got back, there was great rejoice in all the temples. After that incident, Tefnut, normally wearing her fathers’ sun disk, was seen as a lioness, or a woman with a lions’ head. Very rarely ever again was she seen portrayed as a full woman. When Tefnut was in the royal court, she wore a crown made of sprouting plants. Sometimes she was seen lying horizontally between the ground and the sky. She was sometimes pictured with her husband, Shu, helping to hold up Nut. She cried with the pain, and when she cried, that made the ground fertilized. Power &amp; magic. Tefnut sat in judgment of the dead in the underworld. Tefnut wears her fathers’ sun disk, a symbol of power. She carries a scepter and wears an ankh, the symbol of life. As she was the goddess of moisture, she was also related to other deities of moisture and wetness. She was seen holding up the sky with her brother/husband Shu. As she was in charge of moisture, she held other roles as well. Some of them were: Order, justice, time, the weather,He
Sobek was the ancient Egyptian god of the Nile. In art, he was shown with the head of a crocodile. In temples to Sobek, live crocodiles were kept in pools to honor him. Jobs &amp; Roles. Sobek was worshipped wherever the Nile was presenting difficulties. Sobek was the ancient Egyptian god of crocodiles and controlled the waters. Sobek’s role was to protect the pharaoh from evil but it differs with each person. He was the most popular god in Arsinoe (Crocodilopolis in Greek) and was considered the Lord of Faiyu (a place in Egypt). Myths &amp; stories. One day when Sobek was in the Nile, he saw Osiris’ (who was murdered by Set, the god of chaos) body. He was so hungry he could not resist eating part of it. His tongue was cut off as a punishment, which is why crocodiles have no tongues in Egyptian myths. He also caught the sons of Horus when they were born. Physical Appearance. Sobek was seen as a crocodile headed man or very rarely a plain crocodile. Egyptians mummified crocodiles in honor of Sobek. Crocodiles were treated like household pets and were adorned with anklets and other decorative jewels. In temples people kept sacred crocodiles because they thought that they were images of Sobek on earth. The sacred crocodiles were a big attraction, the Egyptian’s believed that if the crocodiles were fed and they accepted their food, you would receive blessings from the God Sobek. Family &amp; friends. Sobek was a friend of Horus. Sobek’s mother Neith was considered the sister of Isis, who was Horus’s mother. This made Sobek the cousin of Horus, which was a very important fact because Horus was a major God. In other myths, Sobek was allied with Set. Set was also sometimes thought of as Sobek's father.

Dar es Salaam (Arabic: دار السلام "Dār as-Salām") is the largest city in East Africa. It has a population of about 4,360,000 people. The city is also Tanzania's richest city. It is an important economic centre.  Dar es Salaam was the capital city of Tanzania until 1996. Even though the capital was moved to Dodoma, Dar es Salaam is still the location of much of the country's government. It is also the capital of the Dar es Salaam Region. The city's name in Arabic means "Abode of Peace". Dar es Salaam was at one time called Mzizima.  Population. The population of Dar es Salaam is increasing at a rate of 4.39% each year. It is the 3rd fastest growing city in Africa and the 9th fastest in the world. The metropolitan area population is expected to reach 5.12 million people by 2020.  This rate is far above the world average. Globally, the growth rate of the human population has been declining since a peak in 1962 and 1963 of 2.20% per annum. In 2009 the estimated annual growth rate was 1.1%. Dar es Salaam's rapidly expanding population presents both significant challenges and opportunities. Infrastructure development has not kept pace with the population growth so there is significant resource pressure, especially on road networks and the national power grid. However, a sizeable population with a growing middle class continues to attract investment in areas such as retail (shopping malls), entertainment (cinemas) and communication (high speed internet). Geography. Dar es Salaam is located on a large harbour on the Eastern Indian Ocean coast of Africa. Dar es Salaam has a tropical savanna climate ("Aw" in the Koeppen climate classification). This is because it is very near the equator and the warm Indian Ocean. The city usually has hot and humid weather during much of the year. Each year the area has two rainy seasons. These are called 'the long rains' (in April and May) and 'the short rains' (in
The U.S. National Hurricane Center (NHC) is a department of the National Weather Service, and a component of the National Centers For Environmental Protection. It is responsible for tracking and forecasting the likely behavior of tropical and subtropical cyclones, potential tropical cyclones, and disturbances. The NHC headquarters is in Miami, Florida. When tropical storm or hurricane conditions are predicted within 48 hours on land, the center issues the proper watches through the news media and NOAA Weather Radio. When those conditions are expected within 36 hours, a warning will be issued. Although it is an organization of the United States, the World Meteorological Organization (WMO) has designated the NHC as Regional Specialised Meteorological Center for the North Atlantic and eastern and central Pacific Ocean. In other words, the NHC is the central source of information for all tropical cyclone forecasts and observations happening in these areas, whatever their effect on the US. The NHC does not come up with their own names, but the WMO comes up with the names instead.
Gaborone is the capital city of Botswana. It has a population of 231,626 people. Gaborone is one of the fastest-growing cities in Africa. Gaborone is on the Notwane River in the southeastern corner of Botswana. It is from the South African border. The main campus of the University of Botswana is in the city. Gaborone's airport, Sir Seretse Khama International Airport, is Botswana's main international airport. History. Before 1969, the city was known as Gaberones. Gaberones replaced Mafeking as the capital of the Bechuanaland Protectorate in 1965. Mafeking was outside the Bechuanaland Protectorate. It was in an area of South Africa. When the Protectorate became independent, Botswana needed a capital city that was inside the country. It had been thought that Lobatse would be the capital. It was later decided that they would create a new capital next to Gaberones, a small colonial administrative settlement. The original name, Gaberones, is from Gaborone's Village. It was named after Chief Kgosi Gaborone of the BaTlokwa tribe. His village, now called Tlokweng, was just across a river from the "Government Camp" (colonial government headquarters). "Gabs" is still a common nickname for Gaborone. A newer nickname for Gaborone is G-City. The centre of the city was constructed in three years. It includes Assembly buildings, government offices, a power station, a hospital, schools, a radio station, a telephone exchange, police stations, a post office, and more than 1,000 houses. Much of the city was in place for Independence Day on September 30 1966, when the county became independent of the United Kingdom. The first mayor of Gaborone was Rev J. D. Jones. The old Gaberones became a suburb of the new Gaborone, and is now known as "the Village".
Libreville is the capital city of Gabon. It is the largest city in that country. The city has a population of 578,156 people. Libreville is a port on the Gabon River, near the Gulf of Guinea. It is a trade center for a timber region. The Libreville International Airport, the headquarters for Air Gabon, is about north of the city. History. The Mpongwé tribe lived in the area long before the French took control of the land in 1839. The city was founded (as Gabon) in 1843 as a trading station. Freed slaves were sent there from the ship L'Elizia. In 1848 it was named Libreville (French for "Freetown"). It was the chief port of French Equatorial Africa from 1934 to 1946. Libreville was named in after Freetown. It grew slowly as a trading post and a minor administrative centre. It had a population of 31,000 when it became independent in 1960. Since independence, the city has grown more quickly. Nearly half the of the people of Gabon live in the city. Things to see. Sights in Libreville include the National Museum of Arts and Traditions, the French cultural centre, St Marie’s Cathedral, the carved wood church of St Michael, Nkembo, the Arboretum de Sibang and two cultural villages. Gabon's school of administration and school of law are in Libreville. The Omar Bongo University is also in Libreville. Industry. The city is home to a shipbuilding industry, brewing industry and sawmills. The city exports raw materials such as wood, rubber and cocoa from the city's main port, and the deepwater port at Owendo.
The Brahmaputra ( son of brahma ), also called Tsangpo in Tibet, is one of the main rivers in Asia. It has its origin in the Himalayas of Tibet. It flows through Tibet, India and Bangladesh. It is long. Massive flooding occurs when the ice melts in the Spring. The Brahmaputra’s source is the Chemayungdung Glacier, which covers the slopes of the Himalayas. It joins with the Ganges river and empties into the Bay of Bengal and also forms the Gangetic delta, which is the largest delta in India.
Lilongwe is the capital city of African country of Malawi. It lies in the center of the country on the Lilongwe river. It is near the border of Malawi, Mozambique, and Zambia. The city has a population of 597,619 people. Lilongwe is the second largest city in Malawi. Climate. Lilongwe has a damp subtropical climate, bordering a subtropical highland climate (Köppen: Cwa), with pleasantly warm summers and mild winters. Due to its altitude, temperatures are lower than other cities located in the tropics. Lilongwe has a short wet season from December to March and a long dry season during much of the rest of the year. However it has a strong rain season, with around during the wettest months. History. The city started as a small village on the banks of the Lilongwe river. It became a British colonial administrative centre at the beginning of the 20th century. In 1974, the capital of the country was moved from Zomba to Lilongwe. Recently, as part of a change in politics in Malawi, the parliament has been moved to Lilongwe. All parliament members must spend time in the new capital. Lilongwe is now the political centre of Malawi, but Blantyre the economic capital of the country. Transport. Lilongwe is visited by Malawi Railways and Shire Bus Lines, local buses and minibuses go between Old Town, City Centre, Kamuzu International Airport, and other urban places, including Mzuzu and Blantyre. People can get taxis from hotels and a taxi lane on Presidential Way, North of City Centre Shopping Centre. Most roads have a lot of traffic, so most Malawians prefer to, or can only afford to, walk or use a bicycle. There is also an airport, Kamuzu International Airport, which is about 35 km north of Lilongwe.
Shu was the ancient Egyptian god of dry air, and so was a calming and cooling influence. He was also like Atlas from Greek mythology—his job was to separate Nut and Geb Power and Magic. Shu had warlike traits like strength, speed and stamina and became associated with the pharaoh. He takes a human form wearing a plume (the hieroglyph of his name) on his head and with his arms raised supporting the sky-goddess. Nut to keep her apart from her consort the earth god Geb. Shu was described as dwelling in the sun's disk. He often appeared as a bearded man holding up the sky while protecting the earth. At times he was depicted as a lion or a human with a lion's head. At other times he wore four ostrich feathers. These feathers symbolized the four columns that held up the sky when Shu himself was not there to do the job. When in his role as god of light, Shu carried a sun disk. Hymn. "That is my daughter, the living female one, Tefnut, who shall be with her brother Shu. Life is his name, Order is her name. [At first] I lived with my two children, my little ones, the one before me, the other behind me. Life reposed with my daughter Order, the one within me, the other without me. I rose over them, but their arms were around me." Was a hymn to Shu. Ancient Egyptians prayed to him for a good life and prayed to him for light. People worshipped Shu in prayers, hymns, and in a chapel. People gave him offerings. Shu appeared in tombs and temples. He was a well known god. Temples. Shu belongs to the cosmic deities and as such no temples were dedicated to him. Cosmic deity's were never worshipped in a personified form, therefore there was no need for temples to worshipped them. A chapel was built to Shu, Atum, and Tefnut. No festivals has been historically verified Shu was worshipped through prayers and gatherings. Worshipped. Shu was the god of the water,
Malabo is the capital city of Equatorial Guinea. It is on the northern coast of Bioko Island. The number of people living there has grown quickly over the past ten years to about 100,000. Notable buildings in Malabo include Malabo Cathedral and the Malabo Court Building. The city is served by Malabo International Airport, while ferries sail from its port to Douala and Bata. History. The city was first founded by the British in 1827. They paid Spain for use of the island during colonial times. The British named the city Port Clarence. It was used as a naval station help stop the slave trade. Many newly freed slaves settled there before the creation of Sierra Leone as a colony for freed slaves. While many of them later moved to Sierra Leone. When the island returned to Spanish control, Malabo was renamed Santa Isabel. It replaced the town of Bata as the capital of the country in 1969. The city was renamed Malabo in 1973 because President Francisco Macías Nguema wanted to replace European place names with "authentic" African ones.

""Shield volcanoes" redirects here." A shield volcano is a large volcano with shallowly-sloping sides. The name derives from a translation of "Skjaldbreiður", an Icelandic shield volcano whose name means "broad shield," from its resemblance to a warrior's shield.  Shield volcanoes are usually formed by lava that flows easily. Consequently, a volcanic mountain having a broad profile is built up over time by flow after flow of relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. Many of the largest volcanoes on Earth are shield volcanoes.  The largest is Mauna Loa on the Big Island of Hawaii. Shield volcanoes can be so large they are sometimes considered a mountain range, such as the and the Rainbow Range, both of which are in Canada. These shield volcanoes formed when the North American Plate moved over a hotspot similar to the one feeding the Hawaiian Islands, called the Anahim hotspot. There are also shield volcanoes, for example, in Washington, Oregon, and the Galapagos Islands. The Piton de la Fournaise, on Réunion Island, is one of the more active shield volcanoes on earth, with one eruption per year on average. Shield volcanoes are known to form on other planets. The largest known mountain in the solar system, Olympus Mons on Mars, is a shield volcano. Shield volcanoes on Mars are higher and much more massive than those on Earth.  On Earth, because of plate tectonics, hotspot volcanoes eventually move away from the source of their magma and the volcanoes are individually less massive than might otherwise be the case. Shield volcanoes usually occur along constructive boundaries or above hotspots. However, the many large shield volcanoes of the Cascade Range of northern California and Oregon are over a more complex environment. On other planets. Shield volcanoes are not only found on Earth, they can also be found on Mars, Venus, and Io, which is a moon of Jupiter. The volcanoes on Mars are bigger than those on Earth.
