Gordon Sutherland
Sir Gordon Brims Black McIvor Sutherland FRS (8 April 1907 – 27 June 1980) was a Scottish physicist. Biography Sutherland was born on 8 April 1907 at Watten, Caithness. He was the youngest of seven children of Peter Sutherland and Eliza Hope (née Morrison), both teachers. He was taught by his parents until he was ten, when he attended Leven Academy for a year before moving to Morgan Academy in Dundee for 6 years. From there he went to the University of St Andrews where he took the unusual route of studying for a double degree: an MA in mathematics and applied mathematics, and a BSc in physics. This involved a 5-year combination of courses that had not been taken before. He graduated in 1928 and 1929 with first-class honours in each. Sutherland’s first research work was at Trinity College, Cambridge under Ralph H. Fowler, but after a year he concluded that he did not have the mathematical ability to be a good theoretical physicist, so he switched to experimental work on R ...

David M
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

American Academy Of Arts And Sciences
The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a thorough petition, review, and election process. The academy's quarterly journal, ''Dædalus'', is published by MIT Press on behalf of the academy. The academy also conducts multidisciplinary public policy research. History The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people." The sixty-two incorporating fellows represented varying interests and high standing in the political, professional, and commercial secto ...

Nuclear Magnetic Resonance
Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. This process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei, which depends on the strength of the static magnetic field, the chemical environment, and the magnetic properties of the isotope involved; in practical applications with static magnetic fields up to ca. 20 tesla, the frequency is similar to VHF and UHF television broadcasts (60–1000 MHz). NMR results from specific magnetic properties of certain atomic nuclei. Nuclear magnetic resonance spectroscopy is widely used to determine the structure of organic molecules in solution and study molecular physics and crystals as well as non-crystalline materials. ...

SS United States
SS ''United States'' is a retired ocean liner built between 1950 and 1951 for the United States Lines at a cost of (equivalent to $ million in ). The ship is the largest ocean liner constructed entirely in the United States and the fastest ocean liner to cross the Atlantic in either direction, retaining the Blue Riband for the highest average speed since her maiden voyage in 1952 and still holds title today. She was designed by American naval architect William Francis Gibbs and could be converted into a troopship if required by the Navy in time of war. ''United States'' maintained an uninterrupted schedule of transatlantic passenger service until 1969 and was never used as a troopship. The ship has been sold several times since the 1970s, with each new owner trying unsuccessfully to make the liner profitable. Eventually, the ship's fittings were sold at auction, and hazardous wastes, including asbestos panels throughout the ship, were removed, leaving her almost comple ...

Bomber Command
Bomber Command is an organisational military unit, generally subordinate to the air force of a country. The best known were in Britain and the United States. A Bomber Command is generally used for strategic bombing (although at times, e.g. during the Normandy Landings, may be used for tactical bombing), and is composed of bombers (i.e. planes used to bomb targets). RAF Bomber Command RAF Bomber Command was formed in 1936 to be responsible for all bombing activities of the RAF. It found especial fame during World War II, when its aircraft were used for devastating night-time air raids on Germany and occupied Europe, principally the former, their bombing raids causing tremendous destruction of urban areas and factories. Much of its personnel was drawn from outside the United Kingdom, many coming from the British Empire. Under the British Commonwealth Air Training Plan, many Commonwealth countries contributed squadrons or individuals to British air and ground staff. For example, N ...

2,2,4-Trimethylpentane
2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH3)3CCH2CH(CH3)2. It is one of several isomers of octane (C8H18). This particular isomer is the standard 100 point on the octane rating scale (the zero point is ''n''-heptane). It is an important component of gasoline, frequently used in relatively large proportions (around 10%) to increase the knock resistance of fuel. Strictly speaking, if the standard meaning of ‘iso’ is followed, the name ''isooctane'' should be reserved for the isomer 2-methylheptane. However, 2,2,4-trimethylpentane is by far the most important isomer of octane and historically it has been assigned this name. Production Isooctane is produced on a massive scale in the petroleum industry by alkylation of isobutene with isobutane. This process is conducted in alkylation units in the presence of acid catalysts. It can also be produced from isobutylene by dimerization using an Amberlyst catalyst to p ...

William Penney, Baron Penney
William George Penney, Baron Penney, (24 June 19093 March 1991) was an English mathematician and professor of mathematical physics at the Imperial College London and later the rector of Imperial College London. He had a leading role in the development of High Explosive Research, Britain's clandestine nuclear programme that started in 1942 during the Second World War which produced the first British atomic bomb in 1952. As the head of the British delegation working on the Manhattan Project at Los Alamos Laboratory, Penney initially carried out calculations to predict the damage effects generated by the blast wave of an atomic bomb. Upon returning home, Penney directed the British nuclear weapons directorate, codenamed Tube Alloys and directed scientific research at the Atomic Weapons Research Establishment which resulted in the first detonation of a British nuclear bomb in Operation Hurricane in 1952. After the test, Penney became chief advisor to the new United Kingdom Atomi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
