Life (magazine)
''Life'' was an American magazine published weekly from 1883 to 1972, as an intermittent "special" until 1978, and as a monthly from 1978 until 2000. During its golden age from 1936 to 1972, ''Life'' was a wide-ranging weekly general-interest magazine known for the quality of its photography, and was one of the most popular magazines in the nation, regularly reaching one-quarter of the population. ''Life'' was independently published for its first 53 years until 1936 as a general-interest and light entertainment magazine, heavy on illustrations, jokes, and social commentary. It featured some of the most notable writers, editors, illustrators and cartoonists of its time: Charles Dana Gibson, Norman Rockwell and Jacob Hartman Jr. Gibson became the editor and owner of the magazine after John Ames Mitchell died in 1918.

Atomic Heritage Foundation
The Atomic Heritage Foundation (AHF) is a nonprofit organization originally based in Washington, DC, dedicated to the preservation and interpretation of the Manhattan Project and the Atomic Age and its legacy. Founded by Cynthia Kelly in 2002, the Foundation's stated goal is, "to provide the public not only a better understanding of the past but also a basis for addressing scientific, technical, political, social and ethical issues of the 21st century." AHF works with Congress, the Department of Energy, the National Park Service, state and local governments, nonprofit organizations and the former Manhattan Project communities to preserve and interpret historic sites and develop useful and accessible educational materials for veterans, teachers, and the general public. In June 2019, the Atomic Heritage Foundation and the National Museum of Nuclear Science & History signed an agreement that granted stewardship of the Atomic Heritage Foundation website and all of the AHF's physical co ...

Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

President Truman
Harry S. Truman (May 8, 1884December 26, 1972) was the 33rd president of the United States, serving from 1945 to 1953. A leader of the Democratic Party, he previously served as the 34th vice president from January to April 1945 under Franklin Roosevelt and as a United States senator from Missouri from 1935 to January 1945. Assuming the presidency after Roosevelt's death, Truman implemented the Marshall Plan to rebuild the economy of Western Europe and established both the Truman Doctrine and NATO to contain the expansion of Soviet communism. He proposed numerous liberal domestic reforms, but few were enacted by the conservative coalition that dominated the Congress. Truman grew up in Independence, Missouri, and during World War I fought in France as a captain in the Field Artillery. Returning home, he opened a haberdashery in Kansas City, Missouri, and was elected as a judge of Jackson County in 1922. Truman was elected to the United States Senate from Missouri in 1934. In ...

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, Szilard 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. Szilárd and Met Lab colleague Glenn T. Seaborg co-wrote the report ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago Pile
Chicago Pile-1 (CP-1) was the world's first artificial nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1, during an experiment led by Enrico Fermi. The secret development of the reactor was the first major technical achievement for the Manhattan Project, the Allied effort to create atomic bombs during World War II. Developed by the Metallurgical Laboratory at the University of Chicago, CP-1 was built under the west viewing stands of the original Stagg Field. Although the project's civilian and military leaders had misgivings about the possibility of a disastrous runaway reaction, they trusted Fermi's safety calculations and decided they could carry out the experiment in a densely populated area. Fermi described the reactor as "a crude pile of black bricks and wooden timbers". The reactor was assembled in November 1942, by a team that included Fermi, Leo Szilard (who had previously formulated an idea for non ...

Enrico Fermi
Enrico Fermi (; 29 September 1901 – 28 November 1954) was an Italian (later naturalized American) physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1. He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". He was one of very few physicists to excel in both theoretical physics and experimental physics. Fermi was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and for the discovery of transuranium elements. With his colleagues, Fermi filed several patents related to the use of nuclear power, all of which were taken over by the US government. He made significant contributions to the development of statistical mechanics, Quantum mechanics, quantum theory, and nuclear physics, nuclear and particle physics. Fermi's first major contribution involved the field of statistical mechanics. After Wolfgang Pauli formulated his Pauli exclusion principle, exclusion pri ...
