Szilárd Petition
The Szilárd petition, drafted and circulated in July 1945 by scientist Leo Szilard, was signed by 70 scientists working on the Manhattan Project in Oak Ridge, Tennessee, and the Metallurgical Laboratory in Chicago, Illinois. It asked President Harry S. Truman to inform Japan of the terms of surrender demanded by the allies, and allow Japan to either accept or refuse these terms, before America used atomic weapons. However, the petition never made it through the chain of command to President Truman. It was not declassified and made public until 1961. Later, in 1946, Szilárd jointly with Albert Einstein, created the Emergency Committee of Atomic Scientists that counted among its board, Linus Pauling (Nobel Peace Prize in 1962). Background The petition was preceded by the Franck Report, written by the Committee on the Social and Political Implications of the Atomic Bomb, of which James Franck was the chair.

Petition From Leo Szilard And Other Scientists To President Harry S
A petition is a request to do something, most commonly addressed to a government official or public entity. Petitions to a deity are a form of prayer called supplication. In the colloquial sense, a petition is a document addressed to an official and signed by numerous individuals. A petition may be oral rather than written, or may be transmitted via the Internet. Legal ''Petition'' can also be the title of a legal pleading that initiates a legal case. The initial pleading in a civil lawsuit that seeks only money (damages) might be called (in most U.S. courts) a ''complaint''. An initial pleading in a lawsuit that seeks non-monetary or "equitable" relief, such as a request for a writ of ''mandamus'' or ''habeas corpus'', custody of a child, or probate of a will, is instead called a ''petition''. Act on petition is a "summary process" used in probate, ecclesiastical and divorce cases, designed to handle matters which are too complex for simple motion. The parties in a case exchan ...

Nuclear Arms Race
The nuclear arms race was an arms race competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War. During this same period, in addition to the American and Soviet nuclear stockpiles, other countries developed nuclear weapons, though no other country engaged in Nuclear weapon design, warhead production on nearly the same scale as the two superpowers. The race began during World War II, dominated by the Western Allies' Manhattan Project and Soviet atomic spies. Following the atomic bombings of Hiroshima and Nagasaki, the Soviet Union accelerated Soviet atomic bomb project, its atomic bomb project, resulting in the RDS-1 test in 1949. Both sides then pursued an all-out effort, realizing deployable thermonuclear weapons by the mid-1950s. The arms race in Nuclear weapons testing, nuclear testing culminated with the 1961 Tsar Bomba. Atmospheric testing was ended in the 1963 Partial Nuclear Test Ban Treaty. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
