Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed the "gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945. Concerns about whether the complex Fat Man design would work led to a decision to conduct the first nuclear test. The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, inspired by the poetry of John Donne.
The Tsar Bomba, also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested. The Soviet physicist Andrei Sakharov oversaw the project at Arzamas-16, while the main work of design was by Sakharov, Viktor Adamsky, Yuri Babayev, Yuri Smirnov, and Yuri Trutnev. The project was ordered by Nikita Khrushchev in July 1961 as part of the Soviet resumption of nuclear testing after the Test Ban Moratorium, with the detonation timed to coincide with the 22nd Congress of the Communist Party of the Soviet Union.
Nuclear technology is technology that involves the nuclear reactions of atomic nuclei. Among the notable nuclear technologies are nuclear reactors, nuclear medicine and nuclear weapons. It is also used, among other things, in smoke detectors and gun sights.
The Atomic Cafe is a 1982 American documentary film directed by Kevin Rafferty, Jayne Loader and Pierce Rafferty. It is a compilation of clips from newsreels, military training films, and other footage produced in the United States early in the Cold War on the subject of nuclear warfare. Without any narration, the footage is edited and presented in a manner to demonstrate how misinformation and propaganda was used by the U.S. government and popular culture to ease fears about nuclear weapons among the American public.
The Atomic Age, also known as the Atomic Era, is the period of history following the detonation of the first nuclear weapon, The Gadget at the Trinity test in New Mexico on 16 July 1945 during World War II. Although nuclear chain reactions had been hypothesized in 1933 and the first artificial self-sustaining nuclear chain reaction had taken place in December 1942, the Trinity test and the ensuing bombings of Hiroshima and Nagasaki that ended World War II represented the first large-scale use of nuclear technology and ushered in profound changes in sociopolitical thinking and the course of technological development.
Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity on July 16, 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945. The purpose of the tests was to investigate the effect of nuclear weapons on warships.
Nuclear weapons tests are experiments carried out to determine the performance, yield, and effects of nuclear weapons and have resulted until 2020 in up to 2.4 million people dying from its global fallout. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different conditions, and how personnel, structures, and equipment are affected when subjected to nuclear explosions. However, nuclear testing has often been used as an indicator of scientific and military strength. Many tests have been overtly political in their intention; most nuclear weapons states publicly declared their nuclear status through a nuclear test.
Trinitite, also known as atomsite or Alamogordo glass, is the glassy residue left on the desert floor after the plutonium-based Trinity nuclear bomb test on July 16, 1945, near Alamogordo, New Mexico. The glass is primarily composed of arkosic sand composed of quartz grains and feldspar that was melted by the atomic blast. It was first academically described in American Mineralogist in 1948.
Operation Greenhouse was the fifth American nuclear test series, the second conducted in 1951 and the first to test principles that would lead to developing thermonuclear weapons. Conducted at the new Pacific Proving Ground, on islands of the Enewetak Atoll, it mounted the devices on large steel towers to simulate air bursts. This series of nuclear weapons tests was preceded by Operation Ranger and succeeded by Operation Buster-Jangle.
Elugelab, or Elugelap, was an island, part of the Enewetak Atoll in the Marshall Islands. It was destroyed in the world's first full-scale thermonuclear explosion, the Mike shot of Operation Ivy, on November 1, 1952. Prior to being destroyed, the island was described as "just another small naked island of the atoll".
Jack W. Aeby was an American environmental physicist most famous for having taken the only well-exposed color photograph of the first detonation of a nuclear weapon on July 16, 1945, at the Trinity nuclear test site in New Mexico.
High-altitude nuclear explosions are the result of nuclear weapons testing within the upper layers of the Earth's atmosphere and in outer space. Several such tests were performed at high altitudes by the United States and the Soviet Union between 1958 and 1962.
Upshot–Knothole Grable was a nuclear weapons test conducted by the United States as part of Operation Upshot–Knothole. Detonation of the nuclear weapon, a W9 warhead, occurred 19 seconds after its deployment at 8:30am PDT on May 25, 1953, in Area 5 of the Nevada Test Site.
The National Museum of Nuclear Science & History is a national repository of nuclear science information chartered by the 102nd United States Congress under Public Law 102-190, and located in unincorporated Bernalillo County, New Mexico, with an Albuquerque postal address. It is adjacent to both the Albuquerque city limits and Kirtland Air Force Base.
Radio Bikini is a 1988 American documentary film directed by Robert Stone. It was nominated for an Academy Award in 1988 for Best Documentary Feature. It was later aired on the PBS series The American Experience.
The Day After Trinity is a 1981 documentary film directed and produced by Jon H. Else in association with KTEH public television in San Jose, California.
How to Photograph an Atomic Bomb is a history and photography book written by Peter Kuran and published in 2006 by VCE.
The Bomb is a 2015 American documentary film about the history of nuclear weapons, from theoretical scientific considerations at the very beginning, to their first use on August 6, 1945, to their global political implications in the present day. The film was written and directed by Rushmore DeNooyer for PBS. The project took a year and a half to complete, since much of the film footage and images were only recently declassified by the United States Department of Defense.
Target Nevada Special Film Project (S.F.P.) 281 (1951) is an instructional documentary short film produced by United States Air Force (USAF). The film documents the story of the USAF support to the United States Atomic Energy Commission for 1949–1951 continental atom bomb tests. In an era of postwar "atomic scare" films, Target Nevada is a straightforward documentary film on nuclear weapons testing.
