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 ZND detonation model is a one-dimensional model for the process of detonation of an explosive.It was proposed during World War II independently by Yakov Zeldovich, [1] John von Neumann, [2] and Werner Döring, [3] hence the name.
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 .
[6] von Neumann published his results in August 1947 in the Los Alamos scientific laboratory report on "Blast wave" (PDF). Archived (PDF) from the original on June 1, 2022., although that report was distributed only in 1958. [7] Taylor got clearance to publish his results in 1949 and he published his works in two papers in 1950.
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.
A physical interpretation of the condition is usually based on the later modelling (c. 1943) by Yakov Borisovich Zel'dovich, [5] John von Neumann, [6] and Werner Döring [7] (the so-called ZND detonation model).
However, Oppenheimer, Groves and Parsons lobbied Purnell and Tolman to get John von Neumann to have a look at the problem. Von Neumann suggested the use of shaped charges to initiate implosion. [52] A gun-type nuclear bomb. Oppenheimer considered that there was a "reciprocal lack of confidence" between Parsons and Neddermeyer, [53] and in ...
