Nuclear Energy In Germany
Nuclear power was used in Germany from the 1960s until it was fully phased out in April 2023. German nuclear power began with research reactors in the 1950s and 1960s, with the first commercial plant coming online in 1969. By 1990, nuclear power accounted for about a quarter of the electricity produced in the country. Nuclear power accounted for 13.3% of German electricity supply in 2021, supplied by six power plants. Three of these were switched off at the end of 2021, and the other three ceased operations by April 2023. The anti-nuclear movement in Germany has a long history dating back to the early 1970s and intensified following the Chernobyl disaster in 1986. After the March 2011 Fukushima nuclear disaster and subsequent anti-nuclear protests, the government announced that it would close all of its nuclear power plants by 2022. Eight of the 17 operating reactors in Germany were permanently shut down following Fukushima. While nuclear power was gradually phased out of the G ...

Lise Meitner
Elise Lise Meitner ( ; ; 7 November 1878 – 27 October 1968) was an Austrian-Swedish nuclear physicist who was instrumental in the discovery of nuclear fission. After completing her doctoral research in 1906, Meitner became the second woman from the University of Vienna to earn a doctorate in physics. She spent much of her scientific career in Berlin, where she was a physics professor and a department head at the Max Planck Institute for Chemistry, Kaiser Wilhelm Institute for Chemistry. She was the first woman to become a full professor of physics in Germany. She lost her positions in 1935 because of the anti-Jewish Nuremberg Laws of Nazi Germany, and the 1938 Anschluss resulted in the loss of her Austrian citizenship. On 13–14 July 1938, she fled to the Netherlands with the help of Dirk Coster. She lived in Stockholm for many years, ultimately becoming a Swedish citizen in 1949, but relocated to Britain in the 1950s to be with family members. In mid-1938, chemists Otto H ...

Kahl Nuclear Power Plant
The Kahl plant was the first nuclear power plant ever to be built in Germany. It was located in Karlstein am Main and was an (at the time) experimental boiling water reactor. It was built by General Electric and supplied by Siemens. At the end of 2008, the demolition works had been finished. The station was the subject of the 1961 short documentary film, '' Kahl''.

Industrialised Countries
A developed country, or advanced country, is a sovereign state that has a high quality of life, developed economy, and advanced technological infrastructure relative to other less industrialized nations. Most commonly, the criteria for evaluating the degree of economic development are the gross domestic product (GDP), gross national product (GNP), the per capita income, level of industrialization, amount of widespread infrastructure and general standard of living. Which criteria are to be used and which countries can be classified as being developed are subjects of debate. Different definitions of developed countries are provided by the International Monetary Fund and the World Bank; moreover, HDI ranking is used to reflect the composite index of life expectancy, education, and income per capita. In 2025, 40 countries fit all three criteria, while an additional 21 countries fit two out of three. Developed countries have generally more advanced post-industrial economies, m ...

Manhattan Project
The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons. It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the bombs. The Army program was designated the Manhattan District, as its first headquarters were in Manhattan; the name gradually superseded the official codename, Development of Substitute Materials, for the entire project. The project absorbed its earlier British counterpart, Tube Alloys, and subsumed the program from the American civilian Office of Scientific Research and Development. The Manhattan Project employed nearly 130,000 people at its peak and cost nearly US$2 billion (equivalent to about $ b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alsos Mission
The Alsos Mission was an organized effort by a team of British and United States military, scientific, and intelligence personnel to discover enemy scientific developments during World War II. Its chief focus was to investigate the progress that Germany was making in the area of nuclear technology, and to seize any German nuclear resources that would either be of use to the Manhattan Project or worth denying to the Soviet Union. It also investigated German chemical and biological weapon development and the means to deliver them, and any other advanced Axis technology it was able to get information about in the course of the other investigations (such as the V-2 rocket program). The Alsos Mission was created after the September 1943 Allied invasion of Italy as part of the Manhattan Project's mission to coordinate foreign intelligence related to enemy nuclear activity. The team had a twofold assignment: search for personnel, records, material, and sites to evaluate the above progr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a Nuclear fission, fission nuclear chain reaction. They are used for Nuclear power, commercial electricity, nuclear marine propulsion, marine propulsion, Weapons-grade plutonium, weapons production and Research reactor, research. Fissile material, Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutron, neutrons and split, releasing energy and multiple neutrons, which can induce further fission. Reactors stabilize this, regulating Neutron absorber, neutron absorbers and neutron moderator, moderators in the core. Fuel efficiency is exceptionally high; Enriched uranium#Low-enriched uranium (LEU), low-enriched uranium is 120,000 times more energy dense than coal. Heat from nuclear fission is passed to a working fluid Nuclear reactor#By coolant, coolant. In commercial reactors, this drives Turbine, turbines and electrical generator shafts. Some reactors are used for district heating, and isotopes, isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Werner Heisenberg
Werner Karl Heisenberg (; ; 5 December 1901 – 1 February 1976) was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics and a principal scientist in the German nuclear program during World War II. He published his Umdeutung paper, ''Umdeutung'' paper in 1925, a major reinterpretation of old quantum theory. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, his matrix mechanics, matrix formulation of quantum mechanics was substantially elaborated. He is known for the uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics". Heisenberg also made contributions to the theories of the Fluid dynamics, hydrodynamics of turbulent flows, the atomic nucleus, ferromagnetism, cosmic rays, and subatomic particles. He introduced the concept of a wave function collapse. He was also instrumental in planning the first West Germa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranverein
Nazi Germany undertook several research programs relating to nuclear technology, including nuclear weapons and nuclear reactors, before and during World War II. These were variously called () or (). The first effort started in April 1939, just months after the discovery of nuclear fission in Berlin in December 1938, but ended shortly ahead of the September 1939 German invasion of Poland, for which many German physicists were drafted into the . A second effort under the administrative purview of the 's began on September 1, 1939, the day of the invasion of Poland. The program eventually expanded into three main efforts: (nuclear reactor) development, uranium and heavy water production, and uranium isotope separation. Eventually, the German military determined that nuclear fission would not contribute significantly to the war, and in January 1942 the turned the program over to the Reich Research Council () while continuing to fund the activity. The program was split up among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jewish Physics
''Deutsche Physik'' (, "German Physics") or Aryan Physics () 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 appears in 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" (). Origins This movement began as an extension of a German nationalistic movement in the physics community which went back to the start of World War I with Austria's declaration of war on 28 July 1914. On 25 August 1914, during the German Rape 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 ...
