Kernphysikalische Forschungsberichte
''Kernphysikalische Forschungsberichte'' (''Research Reports in Nuclear Physics'') was an internal publication of the German ''Uranverein'', which was initiated under the ''Heereswaffenamt'' (Army Ordnance Office) in 1939; in 1942, supervision of the ''Uranverein'' was turned over to the Reichsforschungsrat under the Reichserziehungsministerium. Reports in this publication were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. Many of the reports are available at the Karlsruhe Nuclear Research Center and the Niels Bohr Library of the American Institute of Physics. Many of them are reprinted and transcribed in the book "''Collected Works / Gesammelte Werke''" listed below which is available in most libraries. There are reports n ...

Abraham Esau
Robert Abraham Esau (7 June 1884 – 12 May 1955) was a German physicist. After receipt of his doctorate from the University of Berlin, Esau worked at Telefunken, where he pioneered very high frequency (VHF) waves used in radar, radio, and television, and he was president of the ''Deutscher Telefunken Verband''. During World War I, he was a prisoner of war of the French; he was repatriated to Germany in 1919. In 1925, he was appointed professor at the University of Jena, where he also served as rector. From 1933, Esau was the State Councilor in Thuringia. From 1937, Esau was head of the physics section of the newly created Reich Research Council (RFR). From 1939, he was a professor at the University of Berlin and president of the Reich Physical and Technical Institute. From his position in the RFR, he initiated the first meeting of the Uranium Club in early 1939, the precursor to the Army Ordnance Office (HWA) German nuclear energy project, which began in September of that year. ...

Reichserziehungsministerium
The Reich Ministry of Science, Education and Culture (german: , also unofficially known as the "Reich Education Ministry" (german: ), or "REM") existed from 1934 until 1945 under the leadership of Bernhard Rust and was responsible for unifying the education system of Nazi Germany and aligning it with the goals of Nazi leadership. Background The REM was the successor to the former ''Preußisches Ministerium für Wissenschaft, Kunst und Volksbildung'' (Prussian Ministry of Science, Art and Culture), creating for the first time in Germany a centralized and hierarchical institution in control of the Reich's education sector. In 1934, the REM took over from the ''Reichsinnenministerium'' (Reich Interior Ministry) the supervision of colleges and universities in Germany, as well as research institutions such as the ''Physikalisch-Technische Reichsanstalt'' (abbreviated PTR; translation: Reich Physical and Technical Institute.); today, the PTR is known as the ''Physikalisch-Technische ...

Reichsforschungsrat
The Reichsforschungsrat was created in Germany in 1936 under the Education Ministry for the purpose of centralized planning of all basic and applied research, with the exception of aeronautical research. It was reorganized in 1942 and placed under the Ministry of Armaments. Creation On the initiative of Erich Schumann, the Reichsforschungsrat (RFR, Reich Research Council) was inaugurated on 16 March 1937 by Reich Minister Bernhard Rust of the Reichserziehungsministerium (REM, Reich Education Ministry). The RFR was set up to centralize planning for all basic and applied research in Germany, with the exception of aeronautical research, which was under the supervision of Reich Marshal Hermann Göring. General Karl Heinrich Emil Becker, head of the ''Heereswaffenamt'' (HWA, Army Ordnance Office) and dean and professor in the faculty of defense technology at the Technische Hochschule Berlin, was its president (1937 to 1940). After Becker’s death in 1940, Rust took over as president of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Fission
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission of heavy elements was discovered on Monday 19 December 1938, by German chemist Otto Hahn and his assistant Fritz Strassmann in cooperation with Austrian-Swedish physicist Lise Meitner. Hahn understood that a "burst" of the atomic nuclei had occurred. Meitner explained it theoretically in January 1939 along with her nephew Otto Robert Frisch. Frisch named the process by analogy with biological fission of living cells. For heavy nuclides, it is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). Like nuclear fusion, for fission to produce energy, the total binding energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Docent
The title of docent is conferred by some European universities to denote a specific academic appointment within a set structure of academic ranks at or below the full professor rank, similar to a British readership, a French " ''maître de conférences''" (MCF), and equal to or above the title of " associate professor". Docent is also used at some (mainly German) universities generically for a person who has the right to teach. The term is derived from the Latin word ''docēns'', which is the present active participle of ''docēre'' (to teach, to lecture). Becoming a docent is often referred to as Habilitation or doctor of science and is an academic qualification that shows that the holder is qualified to be employed at the level of associate or full professor. Docent is the highest academic title in several countries, and the qualifying criteria are research output that corresponds to 3-5 doctoral dissertations, supervision of PhD students, and experience in teaching at the ...
