Carl Ramsauer
Carl Wilhelm Ramsauer (6 February 1879 – 24 December 1955) was a German professor of physics and research physicist, famous for the discovery of the Ramsauer–Townsend effect. He pioneered the field of electron and proton collisions with gas molecules.Mehra, Volume 1, Part 2, 2001, p. 620. Early life Ramsauer was born in Osternburg, Oldenburg. From 1897 to 1907, he studied at the Munich, Tübingen, Berlin, Kiel, London, and Breslau Universities. He was awarded his doctorate at Kiel.Hentschel, 1966, Appendix F, pp. XLII-XLII. Career From 1907 to 1909, Ramsauer was a teaching assistant to Philipp Lenard in the physics department at the Ruprecht Karl University of Heidelberg. It was here that he conducted research on the quantum effect of the transparency of noble gases to slow electrons, known as the Ramsauer–Townsend effect. Subsequently, he was a staff scientist at the Radiological Institute in Heidelberg. During World War I, he served as an artillery officer. Fr ...

Bundesarchiv Bild 102-05559, Carl Wilhelm Ramsauer
The German Federal Archives or Bundesarchiv (BArch) (german: Bundesarchiv) are the National Archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media ( Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the year ...

German Nuclear Energy Project
The Uranverein ( en, "Uranium Club") or Uranprojekt ( en, "Uranium Project") was the name given to the project in Germany to research nuclear technology, including nuclear weapons and nuclear reactors, during World War II. It went through several phases of work, but in the words of historian Mark Walker, it was ultimately "frozen at the laboratory level" with the "modest goal" to "build a nuclear reactor which could sustain a nuclear fission chain reaction for a significant amount of time and to achieve the complete separation of at least tiny amount of the uranium isotopes." The scholarly consensus is that it failed to achieve these goals, and that despite fears at the time, the Germans had never been close to producing nuclear weapons. The first effort started in April 1939, just months after the discovery of nuclear fission in December 1938, but ended only months later shortly ahead of the German invasion of Poland, when many notable physicists were drafted into the ''Wehrma ...

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 ...

Hermann Göring
Hermann Wilhelm Göring (or Goering; ; 12 January 1893 – 15 October 1946) was a German politician, military leader and convicted war criminal. He was one of the most powerful figures in the Nazi Party, which ruled Germany from 1933 to 1945. A veteran World War I fighter pilot ace, Göring was a recipient of the ("The Blue Max"). He was the last commander of ''Jagdgeschwader'' 1 (Jasta 1), the fighter wing once led by Manfred von Richthofen. An early member of the Nazi Party, Göring was among those wounded in Adolf Hitler's failed Beer Hall Putsch in 1923. While receiving treatment for his injuries, he developed an addiction to morphine which persisted until the last year of his life. After Hitler became Chancellor of Germany in 1933, Göring was named as minister without portfolio in the new government. One of his first acts as a cabinet minister was to oversee the creation of the Gestapo, which he ceded to Heinrich Himmler in 1934. Following the establishment of th ...

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 Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was ... 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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernhard Rust
Bernhard Rust (30 September 1883 – 8 May 1945) was Minister of Science, Education and National Culture ( Reichserziehungsminister) in Nazi Germany.Claudia Koonz, ''The Nazi Conscience'', p 134 A combination of school administrator and zealous Nazi, he issued decrees, often bizarre, at every level of the German educational system to immerse German youth in Nazi ideology. He also served as the party '' Gauleiter'' in Hanover and Brunswick from 1925 to 1940. Early life Rust was born in Hanover and obtained a doctorate in German philology and philosophy. After passing the state teaching examination with the grade "''gut''" (i.e. "good") in 1908, he became a high school teacher at Hanover's Ratsgymnasium, then served in the army during World War I. He reached the rank of '' Oberleutnant'', served as a company commander and was awarded the Iron Cross first and second class for bravery. He was wounded in action and sustained a severe head injury, which caused serious mental and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Prandtl
Ludwig Prandtl (4 February 1875 – 15 August 1953) was a German fluid dynamicist, physicist and aerospace scientist. He was a pioneer in the development of rigorous systematic mathematical analyses which he used for underlying the science of aerodynamics, which have come to form the basis of the applied science of aeronautical engineering. In the 1920s he developed the mathematical basis for the fundamental principles of subsonic aerodynamics in particular; and in general up to and including transonic velocities. His studies identified the boundary layer, thin-airfoils, and lifting-line theories. The Prandtl number was named after him. Early years Prandtl was born in Freising, near Munich, in 1875. His mother suffered from a lengthy illness and, as a result, Ludwig spent more time with his father, a professor of engineering. His father also encouraged him to observe nature and think about his observations. He entered the Technische Hochschule Munich in 1894 and graduated wi ...

Quantum Mechanics
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves ( wave–particle duality); and there ar ...

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert Einstein was concerned with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-Semitic
Antisemitism (also spelled anti-semitism or anti-Semitism) is hostility to, prejudice towards, or discrimination against Jews. A person who holds such positions is called an antisemite. Antisemitism is considered to be a form of racism. Antisemitism has historically been manifested in many ways, ranging from expressions of hatred of or discrimination against individual Jews to organized pogroms by mobs, police, police forces, or genocide. Although the term did not come into common usage until the 19th century, it is also applied to previous and later anti-Jewish incidents. Notable instances of Persecution of Jews, persecution include the Rhineland massacres preceding the First Crusade in 1096, the Edict of Expulsion from England in 1290, the 1348–1351 persecution of Jews during the Black Death, the History of the Jews in Spain#Massacres and mass conversions of 1391, massacres of Spanish Jews in 1391, the persecutions of the Spanish Inquisition, the Alhambra Decree, expulsion ...
