Atomic Spies
Atomic spies or atom spies were people in the United States, the United Kingdom, and Canada who are known to have illicitly given information about nuclear weapons production or design to the Soviet Union during World War II and the early Cold War. Exactly what was given, and whether everyone on the list gave it, are still matters of some scholarly dispute. In some cases, some of the arrested suspects or government witnesses had given strong testimonies or confessions which they recanted later or said were fabricated. Their work constitutes the most publicly well-known and well-documented case of nuclear espionage in the history of nuclear weapons. At the same time, numerous nuclear scientists wanted to share the information with the world scientific community, but this proposal was firmly quashed by the United States government. Atomic spies were motivated by a range of factors. Some, such as ideology or a belief in communism, were committed to advancing the interests of the S ...

George Koval
George Abramovich Koval ( rus, Жорж (Георгий) Абрамович Коваль, p=ˈʐorʐ (ɡʲɪˈorɡʲɪj) ɐˈbraməvʲɪtɕ kɐˈvalʲ, a=Ru-George Abramovich Koval.flac, Zhorzh Abramovich Koval; December 25, 1913 – January 31, 2006) was an American engineer who acted as a Soviet intelligence officer for the Soviet atomic bomb project. Koval's infiltration of the Manhattan Project as a GRU (Soviet military intelligence) agent reduced the time it took for the Soviet Union to develop nuclear weapons. Koval was born in Sioux City, Iowa to Jewish emigrants from the part of the Russian Empire that is now Belarus. As an adult, he traveled with his parents to the Soviet Union to settle in the Jewish Autonomous Region near the Chinese border. Koval was recruited by the GRU, trained, and assigned the code name DELMAR. He returned to the United States in 1940 and was drafted into the U.S. Army in early 1943. Koval worked at atomic research laboratories and, according t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dopant
A dopant (also called a doping agent) is a small amount of a substance added to a material to alter its physical properties, such as electrical or optics, optical properties. The amount of dopant is typically very low compared to the material being doped. When doped into crystalline substances, the dopant's atoms get incorporated into the crystal lattice of the substance. The crystalline materials are frequently either crystals of a semiconductor such as silicon and germanium for use in solid-state electronics, or transparency and translucency, transparent crystals for use in the production of various laser types; however, in some cases of the latter, noncrystalline substances such as glass can also be doped with impurities. In solid-state electronics using the proper types and amounts of dopants in semiconductors is what produces the p-type semiconductors and n-type semiconductors that are essential for making transistors and diodes. Transparent crystals Lasing media The p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leo Szilard
Leo Szilard (; ; born Leó Spitz; February 11, 1898 – May 30, 1964) was a Hungarian-born physicist, biologist and inventor who made numerous important discoveries in nuclear physics and the biological sciences. He conceived the nuclear chain reaction in 1933, and patented the idea in 1936. In late 1939 he wrote the letter for Albert Einstein's signature that resulted in the Manhattan Project that built the atomic bomb, and then in 1945 wrote the Szilard petition asking president Harry S. Truman to demonstrate the bomb without dropping it on civilians. According to György Marx, he was one of the Hungarian scientists known as The Martians. Szilard initially attended Palatine Joseph Technical University in Budapest, but his engineering studies were interrupted by service in the Austro-Hungarian Army during World War I. He left Hungary for Germany in 1919, enrolling at Technische Hochschule (Institute of Technology) in Berlin-Charlottenburg (now Technische Universität ...

Albert Einstein
Albert Einstein (14 March 187918 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics. His mass–energy equivalence formula , which arises from special relativity, has been called "the world's most famous equation". He received the 1921 Nobel Prize in Physics for . Born in the German Empire, Einstein moved to Switzerland in 1895, forsaking his German citizenship (as a subject of the Kingdom of Württemberg) the following year. In 1897, at the age of seventeen, he enrolled in the mathematics and physics teaching diploma program at the Swiss ETH Zurich, federal polytechnic school in Zurich, graduating in 1900. He acquired Swiss citizenship a year later, which he kept for the rest of his life, and afterwards secured a permanent position at the Swiss Patent Office in Bern. In 1905, he submitted a successful PhD dissertation to the University of Zurich. In 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leadership
Leadership, is defined as the ability of an individual, group, or organization to "", influence, or guide other individuals, teams, or organizations. "Leadership" is a contested term. Specialist literature debates various viewpoints on the concept, sometimes contrasting Eastern world, Eastern and Western world, Western approaches to leadership, and also (within the West) North American versus European approaches. Some U.S. academic environments define leadership as "a process of social influence in which a person can enlist the aid and Peer support, support of others in the accomplishment of a common and Ethics, ethical task (project management), task". In other words, leadership is an influential Power (social and political), power-relationship in which the power of one party (the "leader") promotes movement/change in others (the "followers"). Some have challenged the more traditional managerial views of leadership (which portray leadership as something possessed or owned by ...

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] |

Igor Kurchatov
Igor Vasilyevich Kurchatov (; 12 January 1903 – 7 February 1960), was a Soviet physicist who played a central role in organizing and directing the former Soviet program of nuclear weapons, and has been referred to as "father of the Russian atomic bomb". As many of his contemporaries in Russia, Kurchatov, initially educated as a naval architect, was an ''autodidact'' in nuclear physics and was brought by Soviet establishment to accelerate the feasibility of the "super bomb". Aided by effective intelligence management by Soviet agencies on the American Manhattan Project, Kurchatov oversaw the quick development and testing of the first Soviet nuclear weapon, which was roughly based on the first American device, at Semipalatinsk in the Kazakh SSR in 1949. Kurchatov, a recipient of many former Soviet honors, had an instrumental role in modern nuclear industry in Russia. His rapid decline in health is mainly attributed to a 1949 radiation accident in Chelyabinsk-40. Kurch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
