Robert Oppenheimer, American Prometheus, Kai Bird and Martin Sherwin trace the evolution of three intersecting strands of thought that have shaped the modern world: the evolution of communism from its 1930's, quasi-liberal form into a rigid, authoritarian ideology; the evolution of quantum mechanics; and the evolution of our country's thinking about the strategic . The two had similar political views; she wrote for the Western Worker, a Communist Party newspaper. [190], On June 7, 1949, Oppenheimer testified before the House Un-American Activities Committee that he had associations with the Communist Party USA in the 1930s.

In the first of these, a 1938 paper co-written with Robert Serber titled "On the Stability of Stellar Neutron Cores",[49] Oppenheimer explored the properties of white dwarfs. Most people were silent. Rita Oppenheimer were childhood sweethearts, having met at the Ethical Culture School in New York (also attended by J. Robert OPPENHEIMER.) The other group felt that developing the H-bomb would not in fact improve the Western security position and that using the weapon against large civilian populations would be an act of genocide, and advocated instead a more flexible response to the Soviets involving tactical nuclear weapons, strengthened conventional forces, and arms control agreements.

Oppenheimer's achievements in physics included the BornOppenheimer approximation for molecular wave functions, work on the theory of electrons and positrons, the OppenheimerPhillips process in nuclear fusion, and the first prediction of quantum tunneling. [14] He completed the third and fourth grades in one year and skipped half of the eighth grade. After World War II, Oppenheimer published only five scientific papers, one of which was in biophysics, and none after 1950. In 1965, when he was persuaded to quote again for a television broadcast, he said: We knew the world would not be the same. He was on the point of questioning me.

[159] As he later recalled: The program we had in 1949 was a tortured thing that you could well argue did not make a great deal of technical sense. While they marched in protest, the state of Washington outlawed the Communist Party, and required all government employees to swear a loyalty oath. He also instituted temporary memberships for scholars from the humanities, such as T. S. Eliot and George F. Kennan. [264][265] The Day After Trinity, a 1980 documentary about J. Robert Oppenheimer and the building of the atomic bomb, was nominated for an Academy Award and received a Peabody Award. John Earl Haynes, Harvey Klehr and Alexander Vassiliev, Spies: The Rise and Fall of the KGB in America (New Haven: Yale University Press, 2009), p. 58. [17], In 1924, Oppenheimer was informed that he had been accepted into Christ's College, Cambridge. He liked things that were difficult and since much of the scientific work appeared easy for him, he developed an interest in the mystical and the cryptic. His associates fell into two camps: one saw him as an aloof and impressive genius and aesthete, the other as a pretentious and insecure poseur. [85] Debates over Oppenheimer's party membership or lack thereof have turned on very fine points; almost all historians agree he had strong left-wing views during this time and interacted with party members, though there is considerable dispute over whether he was officially a member of the party.

"[258], The question of the scientists' responsibility toward humanity inspired Bertolt Brecht's drama Galileo (1955), left its imprint on Friedrich Drrenmatt's Die Physiker, and is the basis of the opera Doctor Atomic by John Adams (2005), which was commissioned to portray Oppenheimer as a modern-day Faust. Scouting for a site in late 1942, Oppenheimer was drawn to New Mexico, not far from his ranch. Fromet Mendelssohn ne Guggenheim. Was Oppenheimer a member of the Communist Party? [112] This included opinions on such sensitive issues as whether the Soviet Union should be advised of the weapon in advance of its use against Japan. Oppenheimer asked Fermi whether he could produce enough strontium without letting too many in on the secret. "[240], The rehabilitation implied by the award was partly symbolic, as Oppenheimer still lacked a security clearance and could have no effect on official policy, but the award came with a $50,000 tax-free stipend, and its award outraged many prominent Republicans in Congress. In its presentation to the Interim Committee, the scientific panel offered its opinion not just on the likely physical effects of an atomic bomb, but on its likely military and political impact. [188] He had been under close surveillance since the early 1940s, his home and office bugged, his phone tapped and his mail opened. [202] A transcript of the hearings was published in June 1954,[203] with some redactions. When the New York Mineralogical Society invited J.
