Josef-Maria Jauch
Josef Maria Jauch (September 20, 1914 in Lucerne – August 30, 1974 in Geneva) was a Swiss/American theoretical physicist, known for his work on quantum electrodynamics and on the foundations of quantum theory, and leader of the "Geneva School" of mathematical physics. Biography Early life Jauch was born on 20 September 1914 in Lucerne, Switzerland, the son of Josef Alois Jauch (a telegraph operator) and Emma Laura Rosa Jauch (née Conti). He had two older siblings: Adelheid Jauch and Emil Josef Karl Jauch. After his mother died in 1916, his father remarried, and a half-sister was born: Margrit Jauch (Fuchs). At the age of twelve he became fascinated with a fact he found stated in a popular astronomy book, that an orbiting body with period T, if brought to a stop, would fall into the central mass in time T/\sqrt, which he showed could be derived from Kepler's law. Jauch was also interested in music, studying the violin from age twelve with his father, and then professionally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SS Drottningholm
SS ''Drottningholm'' was one of the earliest steam turbine ocean liners. She was designed as a transatlantic liner and mail ship for Allan Line, built in Scotland, and launched in 1904 as RMS ''Virginian''. Her sister ship, , was built in Ireland, launched four months earlier, and was the World's first turbine-powered liner. In the First World War ''Virginian'' spent a few months as a troopship and was then converted into an armed merchant cruiser (AMC). In August 1917 a U-boat damaged her with a torpedo. In 1920 she was sold to the Swedish American Line and remnamed ''Drottningholm''. As a neutral passenger ship during the Second World War she performed notable service repatriating thousands of civilians of various countries on both sides of the war. In 1948 ''Drottningholm'' was then sold to a company in the Italian Home Lines group, who changed her name to ''Brasil''. In 1951 Home Lines chartered her to Hamburg America Line, and the line her name changed again, this time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Jung
Carl Gustav Jung ( ; ; 26 July 1875 – 6 June 1961) was a Swiss psychiatrist and psychoanalyst who founded analytical psychology. Jung's work has been influential in the fields of psychiatry, anthropology, archaeology, literature, philosophy, psychology, and religious studies. Jung worked as a research scientist at the Burghölzli psychiatric hospital, in Zurich, under Eugen Bleuler. During this time, he came to the attention of Sigmund Freud, the founder of psychoanalysis. The two men conducted a lengthy correspondence and collaborated, for a while, on a joint vision of human psychology. Freud saw the younger Jung as the heir he had been seeking to take forward his "new science" of psychoanalysis and to this end secured his appointment as president of his newly founded International Psychoanalytical Association. Jung's research and personal vision, however, made it difficult for him to follow his older colleague's doctrine and they parted ways. This division was pe ...

Gregor Wentzel
Gregor Wentzel (17 February 1898 – 12 August 1978) was a German physicist known for development of quantum mechanics. Wentzel, Hendrik Kramers, and Léon Brillouin developed the Wentzel–Kramers–Brillouin approximation in 1926. In his early years, he contributed to X-ray spectroscopy, but then broadened out to make contributions to quantum mechanics, quantum electrodynamics, and meson theory. Life and education Gregor Wentzel was born in Düsseldorf, Germany, as the first of four children of Joseph and Anna Wentzel. He married Anna "Anny" Pohlmann in 1929 and his only child, Donat Wentzel, was born in 1934. The family moved to the USA in 1948 until he and Anny returned to Ascona, Switzerland in 1970. Career Wentzel began his university education in mathematics and physics in 1916, at the University of Freiburg. During 1917 and 1918, he served in the armed forces during World War I.

Erich Hecke
Erich Hecke (20 September 1887 – 13 February 1947) was a German mathematician known for his work in number theory and the theory of modular forms. Biography Hecke was born in Buk, Province of Posen, German Empire (now Poznań, Poland). He obtained his doctorate in Göttingen under the supervision of David Hilbert. Kurt Reidemeister and Heinrich Behnke were among his students. In 1933 Hecke signed the '' Loyalty Oath of German Professors to Adolf Hitler and the National Socialist State''. Hecke died in Copenhagen, Denmark. André Weil, in the foreword to his text Basic Number Theory says: "To improve upon Hecke, in a treatment along classical lines of the theory of algebraic numbers, would be a futile and impossible task", referring to Hecke's book "Lectures on the Theory of Algebraic Numbers." Research His early work included establishing the functional equation for the Dedekind zeta function, with a proof based on theta functions. The method extended to the L-functions ...

Representation Theory Of Semisimple Lie Algebras
In mathematics, the representation theory of semisimple Lie algebras is one of the crowning achievements of the theory of Lie groups and Lie algebras. The theory was worked out mainly by E. Cartan and H. Weyl and because of that, the theory is also known as the Cartan–Weyl theory. The theory gives the structural description and classification of a finite-dimensional representation of a semisimple Lie algebra (over \mathbb); in particular, it gives a way to parametrize (or classify) irreducible finite-dimensional representations of a semisimple Lie algebra, the result known as the theorem of the highest weight. There is a natural one-to-one correspondence between the finite-dimensional representations of a simply connected compact Lie group ''K'' and the finite-dimensional representations of the complex semisimple Lie algebra \mathfrak g that is the complexification of the Lie algebra of ''K'' (this fact is essentially a special case of the Lie group–Lie algebra corresponden ...

Strong Interaction
The strong interaction or strong force is a fundamental interaction that confines quarks into proton, neutron, and other hadron particles. The strong interaction also binds neutrons and protons to create atomic nuclei, where it is called the nuclear force. Most of the mass of a common proton or neutron is the result of the strong interaction energy; the individual quarks provide only about 1% of the mass of a proton. At the range of 10−15 m (slightly more than the radius of a nucleon), the strong force is approximately 100 times as strong as electromagnetism, 106 times as strong as the weak interaction, and 1038 times as strong as gravitation. The strong interaction is observable at two ranges and mediated by two force carriers. On a larger scale (of about 1 to 3 fm), it is the force (carried by mesons) that binds protons and neutrons (nucleons) together to form the nucleus of an atom. On the smaller scale (less than about 0.8 fm, the radius of a nuc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edward Lee Hill
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned ...
