Science
Science is a systematic endeavor that Scientific method, builds and organizes knowledge in the form of Testability, testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 Common Era, BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the Universe, physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of History of science in classical antiquity, Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the ...

Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend to survive and reproduce more than individuals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Geographical Society
The Royal Geographical Society (with the Institute of British Geographers), often shortened to RGS, is a learned society and professional body for geography based in the United Kingdom. Founded in 1830 for the advancement of geographical sciences, the Society has 16,000 members, with its work reaching the public through publications, research groups and lectures. The Society was founded in 1830 under the name ''Geographical Society of London'' as an institution to promote the 'advancement of geographical science'. It later absorbed the older African Association, which had been founded by Sir Joseph Banks in 1788, as well as the Raleigh Club and the Palestine Association. In 1995 it merged with the Institute of British Geographers, a body for academic geographers, to officially become the Royal Geographical Society ''with IBG''. The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The member ...

Second Zambesi Expedition
The Second Zambezi expedition, from 1858 to 1864, was launched by the Royal Geographical Society of Britain to explore Southeast Africa for mineral deposits and other natural resources. The expedition led to the establishment of the Central Africa Mission and was under the command of Dr. David Livingstone, who would become famous for his journeys into the interior of Africa.

David Livingstone
David Livingstone (; 19 March 1813 – 1 May 1873) was a Scottish physician, Congregationalist, and pioneer Christian missionary with the London Missionary Society, an explorer in Africa, and one of the most popular British heroes of the late 19th-century Victorian era. David was the husband of Mary Moffat Livingstone, from the prominent 18th Century missionary family, Moffat. He had a mythic status that operated on a number of interconnected levels: Protestant missionary martyr, working-class "rags-to-riches" inspirational story, scientific investigator and explorer, imperial reformer, anti-slavery crusader, and advocate of British commercial and colonial expansion. Livingstone's fame as an explorer and his obsession with learning the sources of the Nile River was founded on the belief that if he could solve that age-old mystery, his fame would give him the influence to end the East African Arab–Swahili slave trade. "The Nile sources", he told a friend, "are valuabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Tanganyika
Lake Tanganyika () is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean. Etymology "Tanganika" was the name of the lake that Henry Morton Stanley encountered when he was at Ujiji in 1876. The name first originated from the Bembe language when they arrived in South Kivu around the 7th century, they discovered the lake and started calling it “êtanga ‘ya’ni’â” which means “a big river” in their Bantu language. Stanley found also other names for the lake among different ethnic groups, like the Kimana, the Yemba and the Msaga. An altern ...

John Hanning Speke
Captain John Hanning Speke (4 May 1827 – 15 September 1864) was an English explorer and officer in the British Indian Army who made three exploratory expeditions to Africa. He is most associated with the search for the source of the Nile and was the first European to reach Lake Victoria (known to locals as ''Nam Lolwe'' in Dholuo and ''Nnalubaale'' or ''Ukerewe'' in Luganda). Speke is also known for propounding the Hamitic hypothesis in 1863, in which he supposed that the Tutsi ethnic group were descendants of the biblical figure Ham, and had lighter skin and more Hamitic features than the Bantu Hutu over whom they ruled. Life Speke was born on 4 May 1827 at Orleigh Court, Buckland Brewer, near Bideford, North Devon. In 1844 he was commissioned into the British Army and posted to British India, where he served in the 46th Bengal Native Infantry under Sir Hugh Gough during the Punjab campaign and under Sir Colin Campbell during the First Anglo-Sikh War. He was promot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Francis Burton
Sir Richard Francis Burton (; 19 March 1821 – 20 October 1890) was a British explorer, writer, orientalist scholar,and soldier. He was famed for his travels and explorations in Asia, Africa, and the Americas, as well as his extraordinary knowledge of languages and cultures. According to one count, he spoke twenty-nine languages. Burton's best-known achievements include: a well-documented journey to Mecca in disguise, at a time when non-Muslims were forbidden access on pain of death; an unexpurgated translation of '' One Thousand and One Nights'' (commonly called ''The Arabian Nights'' in English after early translations of Antoine Galland's French version); the publication of the '' Kama Sutra'' in English; a translation of ''The Perfumed Garden'', the "Arab ''Kama Sutra''"; and a journey with John Hanning Speke as the first Europeans to visit the Great Lakes of Africa in search of the source of the Nile.
