John von Neumann (/ v ɒ n ˈ n ɔɪ m ən / von NOY-mən; Hungarian: Neumann János Lajos [ˈnɒjmɒn ˈjaːnoʃ ˈlɒjoʃ]; December 28, 1903 – February 8, 1957) was a Hungarian and American mathematician, physicist, computer scientist and engineer.
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 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. This model admits finite-rate chemical reactions and thus the process of detonation consists of the following ...
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.
According to György Marx, the extraterrestrial origin of the Hungarian scientists is proved by the fact that the names of Leó Szilárd, John von Neumann, and Theodore von Kármán cannot be found on the map of Budapest, but craters can be found on the Moon bearing their names: [2] Szilard, Von Neumann, Von Kármán, and a crater on Mars, Von ...
The limited series, which premiered in February 2025, stars Kaitlyn Dever as Gibson, who launched a media empire after falsely claiming she was fighting cancer in her liver, blood and kidneys ...
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
