Walther Bothe
Walther Wilhelm Georg Bothe (; 8 January 1891 – 8 February 1957) was a German nuclear physicist, who shared the Nobel Prize in Physics in 1954 with Max Born. In 1913, he joined the newly created Laboratory for Radioactivity at the Reich Physical and Technical Institute (PTR), where he remained until 1930, the latter few years as the director of the laboratory. He served in the military during World War I from 1914, and he was a prisoner of war of the Russians, returning to Germany in 1920. Upon his return to the laboratory, he developed and applied coincidence methods to the study of nuclear reactions, the Compton effect, cosmic rays, and the wave–particle duality of radiation, for which he would receive the Nobel Prize in Physics in 1954. In 1930 he became a full professor and director of the physics department at the University of Giessen. In 1932, he became director of the Physical and Radiological Institute at the University of Heidelberg. He was driven out of this posit ...

Oranienburg
Oranienburg () is a town in Brandenburg, Germany. It is the capital of the district of Oberhavel. Geography Oranienburg is a town located on the banks of the Havel river, 35 km north of the centre of Berlin. Division of the town Oranienburg consists of nine districts: * Friedrichsthal * Germendorf * Lehnitz * Malz * Oranienburg * Sachsenhausen * Schmachtenhagen * Wensickendorf * Zehlendorf History Originally named Bötzow, the town of Oranienburg dates from the 12th century and was first mentioned in 1216. Margrave Albert the Bear (ruled 1157–1170) allegedly ordered the construction of a castle on the banks of the Havel. Around the castle stood a settlement of traders and craftsmen. In 1646, Friedrich Wilhelm I of Brandenburg married Louise Henriette of Orange-Nassau (German: ''Oranien-Nassau''). She was so attracted by the town of Bötzow that her husband presented the entire region to her. The princess ordered the construction of a new castle in the Dutch style and ...

Max Born
Max Born (; 11 December 1882 – 5 January 1970) was a German physicist and mathematician who was instrumental in the development of quantum mechanics. He also made contributions to solid-state physics and optics and supervised the work of a number of notable physicists in the 1920s and 1930s. Born won the 1954 Nobel Prize in Physics for his "fundamental research in quantum mechanics, especially in the statistical interpretation of the wave function". Born entered the University of Göttingen in 1904, where he met the three renowned mathematicians Felix Klein, David Hilbert, and Hermann Minkowski. He wrote his PhD thesis on the subject of "Stability of Elastica in a Plane and Space", winning the university's Philosophy Faculty Prize. In 1905, he began researching special relativity with Minkowski, and subsequently wrote his habilitation thesis on the Thomson model of the atom. A chance meeting with Fritz Haber in Berlin in 1918 led to discussion of how an ionic compound is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helmut Rechenberg
Helmut Rechenberg (born November 6, 1937, in Berlin; died November 10, 2016, in Munich) was a German physicist and science historian. Rechenberg studied mathematics, physics and astronomy at the University of Munich and graduated in 1964. At Munich, his work was in experimental physics, studying the magnetism of solids. He moved to the Max Planck Institute for Physics in Munich, where he became Werner Heisenberg's doctoral student. In 1968, he graduated with a doctorate on quantum field theory. From 1970 to 1972 he worked at the University of Texas at Austin, collaborating with George Sudarshan on quantum field theory and with Jagdish Mehra on science history. He then returned to Germany and the Max Planck Institute, from which he officially retired in 2002. His six-volume work with Jagdish Mehra on the history of quantum mechanics has been described as "an extraordinary amount of painstaking scholarship". Rechenberg also co-edited Werner Heisenberg's collected works and from 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humboldt University Of Berlin
Humboldt-Universität zu Berlin (german: Humboldt-Universität zu Berlin, abbreviated HU Berlin) is a German public research university in the central borough of Mitte in Berlin. It was established by Frederick William III on the initiative of Wilhelm von Humboldt, Johann Gottlieb Fichte and Friedrich Ernst Daniel Schleiermacher as the University of Berlin () in 1809, and opened in 1810, making it the oldest of Berlin's four universities. From 1828 until its closure in 1945, it was named Friedrich Wilhelm University (german: Friedrich-Wilhelms-Universität). During the Cold War, the university found itself in East Berlin and was ''de facto'' split in two when the Free University of Berlin opened in West Berlin. The university received its current name in honour of Alexander and Wilhelm von Humboldt in 1949. The university is divided into nine faculties including its medical school shared with the Freie Universität Berlin. The university has a student enrollment of around 32 ...

Max Planck Institute For Nuclear Physics
The Max-Planck-Institut für Kernphysik ("MPI for Nuclear Physics" or MPIK for short) is a research institute in Heidelberg, Germany. The institute is one of the 80 institutes of the Max-Planck-Gesellschaft (Max Planck Society), an independent, non-profit research organization. The Max Planck Institute for Nuclear Physics was founded in 1958 under the leadership of Wolfgang Gentner. Its precursor was the Institute for Physics at the MPI for Medical Research. Today, the institute's research areas are: crossroads of particle physics and astrophysics (astroparticle physics) and many-body dynamics of atoms and molecules (quantum dynamics). The research field of Astroparticle Physics, represented by the divisions of Jim Hinton, Werner Hofmann and Manfred Lindner, combines questions related to macrocosm and microcosm. Unconventional methods of observation for gamma rays and neutrinos open new windows to the universe. What lies behind “dark matter” and “dark energy” is theore ...

Uranverein
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 ''We ...

Deutsche Physik
''Deutsche Physik'' (, "German Physics") or Aryan Physics (german: Arische Physik) was a nationalist movement in the German physics community in the early 1930s which had the support of many eminent physicists in Germany. The term was taken from the title of a four-volume physics textbook by Nobel Laureate Philipp Lenard in the 1930s. ''Deutsche Physik'' was opposed to the work of Albert Einstein and other modern theoretically based physics, which was disparagingly labeled "Jewish physics" (german: Jüdische Physik). Origins This movement began as an extension of a German nationalistic movement in the physics community which went back as far as World War I. On 25 August 1914, during the German invasion of Belgium, German troops used petrol to set fire to the library of the Katholieke Universiteit Leuven. The burning of the library led to a protest note which was signed by eight distinguished British scientists, namely William Bragg, William Crookes, Alexander Fleming, ...
