Henri Daniel Rathgeber
Henri Daniel Rathgeber (11 June 1908 – 20 July 1995) was an Australian physicist who studied cosmic rays but considered his most important contribution to be an economic theory that explain how entropy causes unemployment. Education Rathgeber was born in Paris, Montmartre on 11 June 1908. His father, Daniel Rathgeber was German, working for Robert Bosch GmbH, and his mother Hortense Desmousseaux was French. Just before the outbreak of first world war, he moved to Bad Dürkheim with his French mother, while his father served in the German army. From 1919-1924 he lived in Geneva, Switzerland and went to school at the College. In 1934 he completed an undergraduate degree at the Technische Hochschule in Stuttgart and in 1938 completed his doctorate in physics. During this period the physics department was very active at the Technische Hochschule, with teachers such as Erwin Schrödinger, Erich Regener and Paul Peter Ewald. Rathgeber played an important role in Erich Regene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montmartre
Montmartre ( , ) is a large hill in Paris's northern 18th arrondissement. It is high and gives its name to the surrounding district, part of the Right Bank. The historic district established by the City of Paris in 1995 is bordered by Rue Caulaincourt and Rue Custine on the north, the Rue de Clignancourt on the east and the Boulevard de Clichy and Boulevard de Rochechouart to the south, containing . Montmartre is primarily known for its artistic history, the white-domed Basilica of the Sacré-Cœur on its summit, as well as a nightclub district. The other church on the hill, Saint Pierre de Montmartre, built in 1147, was the church of the prestigious Montmartre Abbey. On 15 August 1534, Saint Ignatius of Loyola, Saint Francis Xavier and five other companions bound themselves by vows in the Martyrium of Saint Denis, 11 Rue Yvonne Le Tac, the first step in the creation of the Jesuits. Near the end of the 19th century and at the beginning of the 20th, during the Belle Époq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erwin Schrödinger
Erwin Rudolf Josef Alexander Schrödinger (, ; ; 12 August 1887 – 4 January 1961), sometimes written as or , was a Nobel Prize-winning Austrian physicist with Irish citizenship who developed a number of fundamental results in quantum theory: the Schrödinger equation provides a way to calculate the wave function of a system and how it changes dynamically in time. In addition, he wrote many works on various aspects of physics: statistical mechanics and thermodynamics, physics of dielectrics, colour theory, electrodynamics, general relativity, and cosmology, and he made several attempts to construct a unified field theory. In his book '' What Is Life?'' Schrödinger addressed the problems of genetics, looking at the phenomenon of life from the point of view of physics. He also paid great attention to the philosophical aspects of science, ancient, and oriental philosophical concepts, ethics, and religion. He also wrote on philosophy and theoretical biology.

University Of Stuttgart Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens ...

Information Theory
Information theory is the scientific study of the quantification, storage, and communication of information. The field was originally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s. The field is at the intersection of probability theory, statistics, computer science, statistical mechanics, information engineering, and electrical engineering. A key measure in information theory is entropy. Entropy quantifies the amount of uncertainty involved in the value of a random variable or the outcome of a random process. For example, identifying the outcome of a fair coin flip (with two equally likely outcomes) provides less information (lower entropy) than specifying the outcome from a roll of a die (with six equally likely outcomes). Some other important measures in information theory are mutual information, channel capacity, error exponents, and relative entropy. Important sub-fields of information theory include s ...

Claude Shannon
Claude Elwood Shannon (April 30, 1916 – February 24, 2001) was an American mathematician, electrical engineer, and cryptographer known as a "father of information theory". As a 21-year-old master's degree student at the Massachusetts Institute of Technology (MIT), he wrote his thesis demonstrating that electrical applications of Boolean algebra could construct any logical numerical relationship. Shannon contributed to the field of cryptanalysis for national defense of the United States during World War II, including his fundamental work on codebreaking and secure telecommunications. Biography Childhood The Shannon family lived in Gaylord, Michigan, and Claude was born in a hospital in nearby Petoskey. His father, Claude Sr. (1862–1934), was a businessman and for a while, a judge of probate in Gaylord. His mother, Mabel Wolf Shannon (1890–1945), was a language teacher, who also served as the principal of Gaylord High School. Claude Sr. was a descendant of New ...

Silvio Gesell
Johann Silvio Gesell (; 17 March 1862 – 11 March 1930) was a German-Argentine economist, merchant, and the founder of Freiwirtschaft, an economic model for market socialism. In 1900 he founded the magazine ''Geld-und Bodenreform'' (''Monetary and Land Reform''), but it soon closed for financial reasons. During one of his stays in Argentina, where he lived in a vegetarian commune, Gesell started the magazine ''Der Physiokrat'' together with Georg Blumenthal. In 1914, it closed due to censorship. The Bavarian Soviet Republic, in which he participated, had a violent end and Gesell was detained for several months on a charge of treason, but was acquitted by a Munich court after a speech he gave in his own defense. Life Silvio Gesell's mother was Walloon and his father was German, originally from Aachen, who worked as a clerk in the then- Prussian district of Malmedy, now part of Belgium. Silvio was the seventh of nine children. After visiting the public Bürgerschule in S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Syme Research Prize
The David Syme Research Prize is an annual award administered by the University of Melbourne for the best original research work in biology, physics, chemistry or geology, produced in Australia during the preceding two years, particular preference is given to original research to enhance industrial and/or commercial development. The Prize was created at the university in 1904 when Melbourne newspaper publisher and owner of ''The Age'' David Syme made a £3,000 bequest for the foundation of the prize. The first prize was awarded in 1906. The publishers of ''The Age'' have continued to fund the award. The prize consists of a medal and of the interest from the original bequest (since 2020 an amount of the order of A$10,000), which may be topped-up further by the publishers. The recipient(s) of the award is chosen by a council selected from the university's Faculty of Science.
