Science
Science is a systematic endeavor that builds and organizes knowledge in the form of 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 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 physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of 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 Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Boveri
Theodor Heinrich Boveri (12 October 1862 – 15 October 1915) was a German zoologist, comparative anatomist and co-founder of modern cytology. He was notable for the first hypothesis regarding cellular processes that cause cancer, and for describing ''chromatin diminution in nematodes''. Boveri was married to the American biologist Marcella O'Grady (1863–1950). Their daughter Margret Boveri (1900–1975) became one of the best-known journalists in post-World War II Germany. Work Using an optical microscope, Boveri examined the processes involved in the fertilization of the animal egg cell; his favorite research objects were the nematode ''Parascaris'' and sea urchins. Boveri's work with sea urchins showed that it was necessary to have all chromosomes present in order for proper embryonic development to take place. This discovery was an important part of the Boveri–Sutton chromosome theory. He also discovered, in 1888, the importance of the centrosome for the formation of th ...

Walter Sutton
Walter Stanborough Sutton (April 5, 1877 – November 10, 1916) was an American geneticist and physician whose most significant contribution to present-day biology was his theory that the Mendelian laws of inheritance could be applied to chromosomes at the cellular level of living organisms. This is now known as the Boveri-Sutton chromosome theory. Early life Sutton was born in Utica, New York, and was raised on a farm as the fifth of seven sons to Judge William B. Sutton and his wife, Agnes Black Sutton, in Russell, Kansas. On the farm, he developed a mechanical aptitude by maintaining and repairing farm equipment, an aptitude that proved helpful later as he worked on oil drilling rigs and with medical instrumentation. University of Kansas After graduating high school in Russell, he enrolled at the University of Kansas in engineering in 1896. Following the death of his younger brother (John) from typhus in 1897, Sutton switched his major to biology with an interest in medic ...

Edward Adrian Wilson
Edward Adrian Wilson (23 July 1872 – 29 March 1912) was an English polar explorer, ornithologist, natural historian, physician and artist. Early life Born in Cheltenham on 23 July 1872, Wilson was the second son and fifth child of physician Edward Thomas Wilson and his wife, Mary Agnes, née Whishaw. A clever, sensitive, but boisterous boy, he developed a love of the countryside, natural history and drawing from an early age. He was sent as a boarder to a preparatory school in Clifton, Bristol, but after failing to gain a scholarship to public school, he attended Cheltenham College for boys as a day pupil. His mother was a poultry breeder and he spent much of his youth at The Crippetts farm, Leckhampton near Cheltenham. By the age of nine, he had announced to his parents that he was going to become a naturalist. With encouragement and tuition from his father, he started to draw pictures of the wildlife and fauna in the fields around the farm. After passing his exams ...

Ernest Shackleton
Sir Ernest Henry Shackleton (15 February 1874 – 5 January 1922) was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration. Born in Kilkea, County Kildare, Ireland, Shackleton and his Anglo-Irish family moved to Sydenham in suburban south London when he was ten. Shackleton's first experience of the polar regions was as third officer on Captain Robert Falcon Scott's ''Discovery'' expedition of 1901–1904, from which he was sent home early on health grounds, after he and his companions Scott and Edward Adrian Wilson set a new southern record by marching to latitude 82°S. During the ''Nimrod'' expedition of 1907–1909, he and three companions established a new record Farthest South latitude at 88°S, only 97 geographical miles (112 statute miles or 180 kilometres) from the South Pole, the largest advance to the pole in ...

Robert Falcon Scott
Captain Robert Falcon Scott, , (6 June 1868 – c. 29 March 1912) was a British Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the ''Discovery'' expedition of 1901–1904 and the ill-fated ''Terra Nova'' expedition of 1910–1913. On the first expedition, he set a new southern record by marching to latitude 82°S and discovered the Antarctic Plateau, on which the South Pole is located. On the second venture, Scott led a party of five which reached the South Pole on 17 January 1912, less than five weeks after Amundsen's South Pole expedition. A planned meeting with supporting dog teams from the base camp failed, despite Scott's written instructions, and at a distance of 162 miles (261 km) from their base camp at Hut Point and approximately 12.5 miles (20 km) from the next depot, Scott and his companions died. When Scott and his party's bodies were discovered, they had in their possession the first Antarctic fossils ever discov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discovery Expedition
The ''Discovery'' Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean (explorer), Tom Crean and William Lashly. Its scientific results covered extensive ground in biology, zoology, geology, meteorology and magnetism. The expedition discovered the existence of the only McMurdo Dry Valleys, snow-free Antarctic valleys, which contains the lon ...

Giuseppe Mercalli
Giuseppe Mercalli (21 May 1850 – 19 March 1914) was an Italian volcanologist and Catholic Church, Catholic priest. He is known best for the Mercalli intensity scale for measuring earthquake intensity. Biography Born in Milan, Mercalli was ordained a Roman Catholic priest and soon became a professor of Natural Sciences at the seminary of Milan. The Italy, Italian government appointed him a professor at Domodossola, followed by a job at Reggio di Calabria. He was professor of geology at the University of Catania during the late 1880s and finally was given a job at Naples University. He was also director of the Vesuvius Observatory until the time of his death. Giuseppe Mercalli also observed eruptions of the volcanoes Stromboli and Vulcano in the Aeolian Islands. His descriptions of these eruptions became the basis for two indices of the Volcanic Explosivity Index: 1 – Strombolian eruption, and 2 – Vulcanian eruption. He also photographed Vesuvius immediately after its er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
