The historian Jeremy Bernstein has pointed out that ironically, "John von Neumann and Klaus Fuchs, produced a brilliant invention in 1946 that could have changed the whole course of the development of the hydrogen bomb, but was not fully understood until after the bomb had been successfully made." [338]
In July 1943, Oppenheimer wrote to John von Neumann, asking for his help, and suggesting that he visit Los Alamos where he could get "a better idea of this somewhat Buck Rogers project". [145] At the time, von Neumann was working for the Navy Bureau of Ordnance, Princeton University, the Army's Aberdeen Proving Ground and the NDRC.
The public release of film footage of the city post-attack, and some research about the effects of the attack, was restricted during the occupation of Japan, [255] but the Hiroshima-based magazine, Chugoku Bunka, in its first issue published on 10 March 1946, devoted itself to detailing the damage from the bombing.
John von Neumann promoted the policy of mutual assured destruction. Dr. Strangelove is a scientist and former Nazi, suggesting Operation Paperclip, the US effort to recruit top German technical talent at the end of World War II. [17] [18] He serves as President Muffley's scientific adviser in the War Room.
In September 1943, mathematician John von Neumann had proposed surrounding a fissile "core" by two different high explosives which produced shock waves of different speeds. Alternating the faster- and slower-burning explosives in a carefully calculated configuration would produce a compressive wave upon their simultaneous detonation.
The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
Between 25 June 1943 and 20 April 1945, the 100th Bomb Group took part in just over 300 missions, and it is eight of those that accounted for nearly half of their losses. On average, a crew ...
Radiation implosion was first developed by Klaus Fuchs and John von Neumann in the United States, as part of their work on the original "Classical Super" hydrogen-bomb design. Their work resulted in a secret patent filed in 1946, and later given to the USSR by Fuchs as part of his nuclear espionage .
