Stephen Hawking was a theoretical physicist known for his work in general relativity and quantum gravity. Here is a summary of his life, work, and publications, based on the sources: Early Life and Education: Hawking was born in Oxford, England, on 8 January 1942, and he died in Cambridge, England, on 14 March 2018. He attended University College, Oxford, for his BA and Trinity Hall, Cambridge, for his PhD. His doctoral advisor was Dennis W. Sciama. Other academic advisors included Robert Berman Scientific Career and Contributions: Hawking's fields of study included general relativity and quantum gravity. He held positions at the University of Cambridge, the California Institute of Technology, and the Perimeter Institute for Theoretical Physics. He is known for several key scientific concepts and theories: His doctoral thesis was titled "Properties of Expanding Universes" (1966). His work also touched on concepts including micro black holes, primordial black holes, the chronology protection conjecture, soft hair, the Bekenstein-Hawking formula, Hawking energy, Hawking-Page phase transition, Gibbons-Hawking ansatz, Gibbons-Hawking effect, Gibbons-Hawking space, Gibbons-Hawking-York boundary term, and the Hartle-Hawking state. Hawking's research explored the singularities of gravitational collapse and cosmology, the wave function of the universe, quantum cosmology, and the origin of structure in the universe. He collaborated with numerous colleagues including Roger Penrose. Publications and Media: Hawking is the author of several popular books, including A Brief History of Time. He also wrote The Universe in a Nutshell, which was structured so that chapters could be read in any order after the first two. Hawking also published Black Holes and Baby Universes. His final work collected some of his most profound writings. He co-authored some of his popular books He wrote forewords for other books. He authored children's fiction He was the subject of films and series including "The Theory of Everything". He made appearances in popular media such as the Monty Python Live (Mostly) show in 2014. He used his fame to advertise products. He applied to trademark his name in 2015. Hawking's academic works are also extensive. Personal Life and Views: Hawking had a disability and used a speech-generating device to communicate. He was involved in disability outreach. He had plans for a trip to space Hawking held personal views on topics such as the relevance of philosophy, the future of humanity, religion and atheism, and politics. Awards and Honors: He received the Hawking Fellowship. He received the Medal for Science Communication. There is also the Stephen Hawking medal for Science Communication. Other: Hawking's work touched on concepts of existential risk from artificial intelligence and related concepts. He made statements on the AI risk of extinction. This summary encapsulates Stephen Hawking's significant contributions to science, literature, and popular culture.
