Don Page (physicist)
Don Nelson Page (born December 31, 1948) is an American-born Canadian theoretical physicist at the University of Alberta, Canada. Work Page's work focuses on quantum cosmology and theoretical gravitational physics, and he is noted for being a doctoral student of Stephen Hawking, who was at Caltech during 1974-1975, in addition to publishing several journal articles with him. Page got his BA at William Jewell College in the United States in 1971, attaining an MS in 1972 and a PhD in 1976 at Caltech. His professional career started as a research assistant in Cambridge from 1976-1979, followed by an assistant professorship at Penn State from 1979-1983, and then an associate professor at Penn State until 1986 before taking on the title of professor in 1986. Page spent four more years at Penn State before moving to become a professor at the University of Alberta in Canada in 1990. In 1993, he argued that if a black hole starts in a pure quantum state and evaporates completely by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Hole Information Paradox
The black hole information paradox is a paradox that appears when the predictions of quantum mechanics and general relativity are combined. The theory of general relativity predicts the existence of black holes that are regions of spacetime from which nothing—not even light—can escape. In the 1970s, Stephen Hawking applied the semiclassical approach of quantum field theory in curved spacetime to such systems and found that an isolated black hole would emit a form of radiation (now called Hawking radiation in his honor). He also argued that the detailed form of the radiation would be independent of the initial state of the black hole, and depend only on its mass, electric charge and angular momentum. The information paradox appears when one considers a process in which a black hole is formed through a physical process and then evaporates away entirely through Hawking radiation. Hawking's calculation suggests that the final state of radiation would retain information only about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canadian Physicists
Canadians () are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity and Canadian values. Canada has also been strongly influenced by its linguistic, geographic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Problem Of Time
In theoretical physics, the problem of time is a conceptual conflict between quantum mechanics and general relativity. Quantum mechanics regards the flow of time as universal and absolute, whereas general relativity regards the flow of time as malleable and relative. This problem raises the question of what time really is in a physical sense and whether it is truly a real, distinct phenomenon. It also involves the related question of why time seems to flow in a single direction, despite the fact that no known physical laws at the microscopic level seem to require a single direction. Time in quantum mechanics In classical mechanics, a special status is assigned to time in the sense that it is treated as a classical background parameter, external to the system itself. This special role is seen in the standard Copenhagen interpretation of quantum mechanics: all measurements of observables are made at certain instants of time and probabilities are only assigned to such measurements. ...

Kalam Cosmological Argument
The Kalam cosmological argument is a modern formulation of the cosmological argument for the existence of God. It is named after the ''Kalam'' (medieval Islamic scholasticism) from which many of its key ideas originated. Philosopher and theologian William Lane Craig was principally responsible for revitalising these ideas for modern academic discourse through his book '' The Kalām Cosmological Argument'' (1979), as well as other publications. The argument's central thesis is the metaphysical impossibility of a temporally past-infinite universe and of actual infinities existing in the real world, traced by Craig to 11th-century Persian Muslim scholastic philosopher Al-Ghazali. This feature distinguishes it from other cosmological arguments, such as Aquinas's Second Way, which rests on the impossibility of a causally ordered infinite regress, and those of Leibniz and Samuel Clarke, which refer to the principle of sufficient reason.

Sean M
Sean, also spelled Seán or Séan in Hiberno-English, is a male given name of Irish origin. It comes from the Irish versions of the Biblical Hebrew name ''Yohanan'' (), Seán (anglicized as '' Shaun/ Shawn/ Shon'') and Séan (Ulster variant; anglicized ''Shane/Shayne''), rendered '' John'' in English and Johannes/Johann/Johan in other Germanic languages. The Norman French ''Jehan'' (see '' Jean'') is another version. In the Irish language, the presence and placement of the síneadh fada is significant, as it changes the meaning of the name. The word "Sean" in Irish means "old", while the word "Séan" means "omen". For notable people named Sean, refer to List of people named Sean. Origin The name was adopted into the Irish language most likely from ''Jean'', the French variant of the Hebrew name ''Yohanan''. As Irish has no letter (derived from ; English also lacked until the late 17th Century, with ''John'' previously been spelt ''Iohn'') so it is substituted by , as was the ...

William Lane Craig
William Lane Craig (; born August 23, 1949) is an American Analytic philosophy, analytic philosopher, Christian apologetics, Christian apologist, author, and theologian. He is a professor of philosophy at Houston Christian University and at the Talbot School of Theology of Biola University. Craig has updated and defended the Kalam cosmological argument for the existence of God. He has also published work where he argues in favor of the historical plausibility of the resurrection of Jesus. His study of divine aseity and Platonism culminated with his book ''God Over All''. Early life and education Craig was born August 23, 1949, in Peoria, Illinois, Peoria, Illinois, to Mallory and Doris Craig. He attended East Peoria Community High School from 1963 to 1967, where he competed in debate and won the state championship in oratory. In September 1965, his junior year, he became a Christian.

Evangelicalism
Evangelicalism (), also called evangelical Christianity or evangelical Protestantism, is a worldwide, interdenominational movement within Protestantism, Protestant Christianity that emphasizes evangelism, or the preaching and spreading of the Gospel, Christian gospel. The term evangelical is derived from the Koine Greek word ''euangelion'', meaning “good news,” in reference to the message of salvation through Jesus Christ. Evangelicalism typically places a strong emphasis on personal conversion to Christianity, conversion, often described as being “born again (Christianity), born again,” and regards the Bible as the ultimate authority in matters of Christian theology, faith and practice. The definition and scope of evangelicalism are subjects of debate among theology, theologians and religious studies, scholars. Some critics argue that the term encompasses a wide and diverse range of beliefs and practices, making it difficult to define as a coherent or unified movement ...
