Edward Teller (Hungarian: Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian and American theoretical physicist and chemical engineer who is known colloquially as "the father of the hydrogen bomb" and one of the creators of the Teller–Ulam design based on Stanisław Ulam's design.
Leaflet sorties were undertaken on 1 and 4 August. Hiroshima may have been leafleted in late July or early August, as survivor accounts talk about a delivery of leaflets a few days before the atomic bomb was dropped. [92] Three versions were printed of a leaflet listing 11 or 12 cities targeted for firebombing; a total of 33 cities listed.
This and other scientific missions to Japan provided valuable data on the effects of the atomic bomb, and led to the creation of the Atomic Bomb Casualty Commission. [324] In anticipation of the bombings, Groves had commissioned physicist Henry DeWolf Smyth to prepare a sanitized technical history of the project for public consumption. The idea ...
This involved writing to Frederick Lindemann, the UK's prime scientific adviser during WW1. However, this failed to dig up evidence as Lindemann reported that actually Szilárd's "security was good to the point of brusqueness". [6] The first atomic bomb, known as Little Boy, was dropped on Hiroshima on August 6, 1945.
After Truman ordered the crash program to develop the hydrogen bomb in January 1950, the Boston Daily Globe published a cutaway description of a hypothetical hydrogen bomb with the caption Artist's conception of how H-bomb might work using atomic bomb as a mere "trigger" to generate enough heat to set up the H-bomb's "thermonuclear fusion" process.
In 1957, hydrogen bomb architect Edward Teller and other Livermore weapons scientists proposed a gigawatt-level electrical plant, based on steam generation from 1 megaton bombs dropped every 12 hours into a 1,000 ft cavity. American research on such plants continued throughout the Cold War.
The first atomic bomb test by the Soviet Union in August 1949 came earlier than Americans expected, and over the next several months, there was an intense debate within the U.S. government, military, and scientific communities over whether to proceed with the development of the far more powerful, nuclear fusion–based hydrogen bomb, then known ...
Klaus Emil Julius Fuchs (29 December 1911 – 28 January 1988) was a German theoretical physicist and atomic spy who supplied information from the American, British, and Canadian Manhattan Project to the Soviet Union during and shortly after World War II.
