Hugh Everett
Hugh Everett III (; November 11, 1930 – July 19, 1982) was an American physicist who first proposed the many-worlds interpretation (MWI) of quantum physics, which he termed his "relative state" formulation. In contrast to the then-dominant Copenhagen interpretation, the MWI posits that the wave function never collapses and that all possibilities of a quantum superposition are objectively real. Discouraged by the scorn of other physicists for MWI, Everett ended his physics career after completing his PhD. Afterwards, he developed the use of generalized Lagrange multipliers for operations research and applied this commercially as a defense analyst and a consultant. In poor health later in life, he died at the age of 51 in 1982. He is the father of musician Mark Oliver Everett. Although largely disregarded until near the end of Everett's lifetime, the MWI received more credibility with the discovery of quantum decoherence in the 1970s and has received increased attention in recen ...

American Management Systems
American Management Systems (previous NASDAQ symbol: AMSY) was a high technology and management consulting firm, founded in 1970 by a group of five former United States Department of Defense, Defense Department officials who had worked under Robert McNamara in the John F. Kennedy, Kennedy and Lyndon Baines Johnson, Johnson administration. The company grew throughout the 1980s and 1990s, implementing key systems such as the accounting system for New York City and The Standard Procurement System for the United States Department of Defense. The company was acquired by CGI Group in 2004, with AMS's federal defense business being acquired by CACI. History AMS was founded in 1970 by five former Defense Department "Whiz Kids": Charles Rossotti, Ivan Selin, Frank Nicolai, Patrick W. Gross, and Jan Lodal. The company's initial headquarters were in the Washington, D.C. suburb of Arlington, Virginia. The founders drew upon research in attribute-value systems and early relational databases dev ...

Bryce DeWitt
Bryce Seligman DeWitt (January 8, 1923 – September 23, 2004), was an American theoretical physicist noted for his work in gravitation and quantum field theory. Life He was born Carl Bryce Seligman, but he and his three brothers, including the noted ichthyologist Hugh Hamilton DeWitt, added "DeWitt" from their mother's side of the family, at the urging of their father, in 1950. In the early-1970s, this change of name so angered Felix Bloch that he blocked DeWitt's appointment to Stanford University and DeWitt and his wife Cecile DeWitt-Morette, a mathematical physicist, accepted faculty positions at the University of Texas at Austin. DeWitt served in World War II as a naval aviator. He died September 23, 2004 from pancreatic cancer at the age of 81. He is buried in France, and was survived by his wife and four daughters. Work He pioneered work in the quantization of general relativity and, in particular, developed canonical quantum gravity, manifestly covariant methods ...

The Catholic University Of America
The Catholic University of America (CUA) is a private university, private Catholic church, Roman Catholic research university in Washington, D.C. It is a pontifical university of the Catholic Church in the United States and the only institution of higher education founded by United States Conference of Catholic Bishops, U.S. Catholic bishops. Established in 1887 as a graduate and research center following approval by Pope Leo XIII, the university began offering undergraduate education in 1904. It is Carnegie Classification of Institutions of Higher Education, classified among "R2: Doctoral Universities – High research activity". Its campus is adjacent to the Brookland (Washington, D.C.), Brookland neighborhood, known as "Little Rome", which contains 60 Catholic institutions, including Trinity Washington University, the Dominican House of Studies, and Archbishop Carroll High School (Washington, D.C.), Archbishop Carroll High School, as well as the Basilica of the National Shrin ...

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Consistent Histories
In quantum mechanics, the consistent histories (also referred to as decoherent histories) approach is intended to give a modern interpretation of quantum mechanics, generalising the conventional Copenhagen interpretation and providing a natural interpretation of quantum cosmology. This interpretation of quantum mechanics is based on a consistency criterion that then allows probabilities to be assigned to various alternative histories of a system such that the probabilities for each history obey the rules of classical probability while being consistent with the Schrödinger equation. In contrast to some interpretations of quantum mechanics, particularly the Copenhagen interpretation, the framework does not include "wavefunction collapse" as a relevant description of any physical process, and emphasizes that measurement theory is not a fundamental ingredient of quantum mechanics. Histories A ''homogeneous history'' H_i (here i labels different histories) is a sequence of Propositio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
