Nth Country Experiment
The ''N''th Country Experiment was an experiment conducted by Lawrence Livermore National Laboratory starting in May 1964 which sought to assess the risk of nuclear proliferation. The experiment consisted in paying three recent young physicists who had just received their PhDs, though had no prior weapons experience, to develop a working nuclear weapon design using only unclassified information, and with basic computational and technical support. "The goal of the participants should be to design an explosive with a militarily significant yield", the report on the experiment read, "A working context for the experiment might be that the participants have been asked to design a nuclear explosive which, if built in small numbers, would give a small nation a significant effect on their foreign relations." The experiment ended on April 10, 1967, after only three man-years of work over two and a half calendar years. According to a heavily redacted declassified version of the summary, it ...

Nuclear Proliferation
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the ''Non-Proliferation Treaty'' or ''NPT''. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (up to and including the so-called countervalue targeting of civilians with nuclear weapons), de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states. Four countries besides the five recognized Nuclear Weapons States have acquired, or are presumed to have acquired, nuclear weapons: India, Pakistan, North Korea, and Israel. None of these four is a party to the NPT, although North Korea acceded to the NPT in 1985, then withdrew in 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physics Experiments
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (. ...

Thermonuclear Bomb
A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make possible the use of non-fissile depleted uranium as the weapon's main fuel, thus allowing more efficient use of scarce fissile material such as uranium-235 () or plutonium-239 (). The first full-scale thermonuclear test was carried out by the United States in 1952; the concept has since been employed by most of the world's nuclear powers in the design of their weapons. Modern fusion weapons consist essentially of two main components: a nuclear fission primary stage (fueled by or ) and a separate nuclear fusion secondary stage containing thermonuclear fuel: the heavy hydrogen isotopes deuterium and tritium, or in modern weapons lithium deuteride. ...

Howard Morland
Howard Morland (born September 14, 1942) is an American journalist and activist against nuclear weapons who, in 1979, became famous for apparently discovering the "secret" of the hydrogen bomb (the Teller–Ulam design) and publishing it after a lengthy censorship attempt by the Department of Energy (''United States v. The Progressive''). Because of some similarities in experience, he became outspoken in the protest against the detention of Mordechai Vanunu. Career Morland graduated from Emory University in 1965 and entered Air Force pilot training, at Lubbock, Texas, aspiring to a career in astronautics or commercial aviation. pp 23, 24. As a C-141 jet transport pilot, he was trained to carry nuclear weapons as cargo. He noted that the full-size bomb casings used in training were astonishingly small, of a size that could easily be mishandled. His wartime assignment was flying from California to Vietnam two to three times a month, returning with combat veterans and the bodies ...

Smyth Report
The Smyth Report (officially ''Atomic Energy for Military Purposes'') is the common name of an administrative history written by American physicist Henry DeWolf Smyth about the Manhattan Project, the Allied effort to develop atomic bombs during World War II. The subtitle of the report is ''A General Account of the Development of Methods of Using Atomic Energy for Military Purposes''. It was released to the public on August 12, 1945, just days after the atomic bombings of Hiroshima and Nagasaki on August 6 and 9. Smyth was commissioned to write the report by Major General (United States), Major General Leslie R. Groves, Jr., the director of the Manhattan Project. The Smyth Report was the first official account of the development of the atomic bombs and the basic physical processes behind them. It also served as an indication as to what information was Declassification, declassified; anything in the Smyth Report could be discussed openly. For this reason, the Smyth Report focu ...

Nuclear Terrorism
Nuclear terrorism refers to any person or persons detonating a nuclear weapon as an act of terrorism (i.e., illegal or immoral use of violence for a political or religious cause). Some definitions of nuclear terrorism include the sabotage of a nuclear facility and/or the detonation of a radiological device, colloquially termed a dirty bomb, but consensus is lacking. In legal terms, nuclear terrorism is an offense committed if a person unlawfully and intentionally "uses in any way radioactive material … with the intent to cause death or serious bodily injury; or with the intent to cause substantial damage to property or to the environment; or with the intent to compel a natural or legal person, an international organization or a State to do or refrain from doing an act", according to the 2005 United Nations International Convention for the Suppression of Acts of Nuclear Terrorism. The possibility of terrorist organizations using nuclear weapons (including those of a small siz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Aristotle Phillips
John Aristotle Phillips (born August 23, 1955) is a U.S. entrepreneur specializing in political campaigns, who became famous for attempting to design a nuclear weapon while a student. "A-Bomb Kid" Phillips was born in August 1955 to Greek immigrant parents and raised in North Haven, Connecticut. In 1976, while attending Princeton University as a junior undergraduate, he designed a nuclear weapon using publicly available books and papers. In February 1977, several months after the story first went public, Phillips was contacted by a Pakistani official trying to purchase his bomb design, an incident addressed on the Senate floor by William Proxmire and Charles Percy. Phillips was a celebrity by this time, dubbed The A-Bomb Kid by the media, and making a series of television appearances including a featured spot on the game show '' To Tell the Truth''. Phillips was an underachieving student who played the tiger mascot at Princeton games. Hoping to stay at the school, he proposed a t ...
