"Fat Man" was the type of nuclear weapon the United States detonated over the Japanese city of Nagasaki on 9 August 1945. It was the second and largest of the only two nuclear weapons ever used in warfare, the first being Little Boy, and its detonation marked the third nuclear explosion in history. The first one was built by scientists and engineers at Los Alamos Laboratory using plutonium manufactured at the Hanford Site and was dropped from the Boeing B-29 Superfortress Bockscar piloted by Major Charles Sweeney.
Little Boy was a type of atomic bomb created by the United States as part of the Manhattan Project during World War II. The name is also often used to describe the specific bomb (L-11) used in the bombing of the Japanese city of Hiroshima by the Boeing B-29 Superfortress Enola Gay on 6 August 1945, making it the first nuclear weapon used in warfare, and the second nuclear explosion in history, after the Trinity nuclear test. It exploded with an energy of approximately 15 kilotons of TNT (63 TJ) and had an explosion radius of approximately 1.3 kilometres (0.81 mi) which caused widespread death across the city. It was a gun-type fission weapon which used uranium that had been enriched in the isotope uranium-235 to power its explosive reaction.
The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons. It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the bombs. The Army program was designated the Manhattan District, as its first headquarters were in Manhattan; the name gradually superseded the official codename, Development of Substitute Materials, for the entire project. The project absorbed its earlier British counterpart, Tube Alloys, and subsumed the program from the American civilian Office of Scientific Research and Development. The Manhattan Project employed nearly 130,000 people at its peak and cost nearly US$2 billion, over 80 percent of which was for building and operating the plants that produced the fissile material. Research and production took place at more than 30 sites across the US, the UK, and Canada.
The Doomsday Clock is a symbol that represents the likelihood of a human-made global catastrophe, in the opinion of the members of the Bulletin of the Atomic Scientists. Created by J. Robert Oppenheimer, Albert Einstein & Eugene Rabinowitch and maintained since 1947, the Clock is a metaphor, not a prediction, for threats to humanity from unchecked scientific and technological advances. That is, the time on the Clock is not to be interpreted as actual time. A hypothetical global catastrophe is represented by midnight on the Clock, with the Bulletin's opinion on how close the world is to one represented by a certain number of minutes or seconds to midnight, which is then assessed in January of each year. The main factors influencing the Clock are nuclear warfare, climate change, and artificial intelligence. The Bulletin's Science and Security Board monitors new developments in the life sciences and technology that could inflict irrevocable harm to humanity.
Building on major scientific breakthroughs made during the 1930s, the United Kingdom began the world's first nuclear weapons research project, codenamed Tube Alloys, in 1941, during World War II. The United States, in collaboration with the United Kingdom, initiated the Manhattan Project the following year to build a weapon using nuclear fission. The project also involved Canada. In August 1945, the atomic bombings of Hiroshima and Nagasaki were conducted by the United States, with British consent, against Japan at the close of that war, standing to date as the only use of nuclear weapons in hostilities.
Power Windows is the eleventh studio album by Canadian rock band Rush, released on October 11, 1985 in Canada by Anthem Records and on October 21, 1985 in the United States. After touring in support of their previous album, Grace Under Pressure (1984), the band took a break and reconvened in early 1985 to begin work on a follow-up. The material continued to display the band's exploration of synthesizer-oriented music, this time with the addition of sampling, electronic drums, a string section, and choir, with power being a running lyrical theme. Power Windows was recorded in Montserrat and England with Peter Collins as co-producer and Andy Richards on additional keyboards.
Operation Hurricane was the first test of a British atomic device. A plutonium implosion device was detonated on 3 October 1952 in Main Bay, Trimouille Island, in the Montebello Islands in Western Australia. With the success of Operation Hurricane, the United Kingdom became the third nuclear power, after the United States and the Soviet Union.
The Soviet atomic bomb project was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II.
"2 Minutes to Midnight" is a song by the English heavy metal band Iron Maiden, featured on their fifth studio album, Powerslave (1984). It was released as the band's tenth single, and first from the album on 6 August 1984. It rose to number 11 on the UK Singles Chart and number 25 on Billboard Top Album Tracks. The band's first single to exceed five minutes in length, it remained their longest until the release of "Infinite Dreams" in November 1989.
"The Big Money" is a song by Canadian rock band Rush, originally released on their 1985 album Power Windows. It peaked at #45 on the Billboard Hot 100 and #4 on the Mainstream Rock chart, and has been included on several compilation albums, such as Retrospective II and The Spirit of Radio: Greatest Hits 1974-1987.
The Interim Committee was a secret high-level group created in May 1945 by United States Secretary of War, Henry L. Stimson at the urging of leaders of the Manhattan Project and with the approval of President Harry S. Truman to advise on matters pertaining to nuclear energy. Composed of prominent political, scientific and industrial figures, the Interim Committee had broad terms of reference which included advising the President on wartime controls and the release of information, and making recommendations on post-war controls and policies related to nuclear energy, including legislation. Its first duty was to advise on the manner in which nuclear weapons should be employed against Japan. Later, it advised on legislation for the control and regulation of nuclear energy. It was named "Interim" in anticipation of a permanent body that would later replace it after the war, where the development of nuclear technology would be placed firmly under civilian control. The Atomic Energy Commission was enacted in 1946 to serve this function.
The Franck Report of June 1945 was a document signed by several prominent nuclear physicists recommending that the United States not use the atomic bomb as a weapon to prompt the surrender of Japan in World War II.
The nuclear weapons debate refers to the controversies surrounding the threat, use and stockpiling of nuclear weapons. Even before the first nuclear weapons had been developed, scientists involved with the Manhattan Project were divided over the use of the weapon. The only time nuclear weapons have been used in warfare was during the final stages of World War II when USAAF B-29 Superfortress bombers dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki in early August 1945. The role of the bombings in Japan's surrender and the U.S.'s ethical justification for them have been the subject of scholarly and popular debate for decades.
The Manhattan Project was a research and development project that produced the first atomic bombs during World War II. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers. The Army component of the project was designated the Manhattan District; "Manhattan" gradually became the codename for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion. Over 90% of the cost was for building factories and producing the fissionable materials, with less than 10% for development and production of the weapons.
Atomic spies or atom spies were people in the United States, the United Kingdom, and Canada who are known to have illicitly given information about nuclear weapons production or design to the Soviet Union during World War II and the early Cold War. Exactly what was given, and whether everyone on the list gave it, are still matters of some scholarly dispute. In some cases, some of the arrested suspects or government witnesses had given strong testimonies or confessions which they recanted later or said were fabricated. Their work constitutes the most publicly well-known and well-documented case of nuclear espionage in the history of nuclear weapons. At the same time, numerous nuclear scientists wanted to share the information with the world scientific community, but this proposal was firmly quashed by the United States government.
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.
