A Brief History of Time: From the Big Bang to Black Holes

CreateSpace Independent Publishing Platform, 2015 M05 29 - 86 páginas
Hawking attempts to explain a range of subjects in cosmology, including the big bang, black holes and light cones, to the nonspecialist reader. His main goal is to give an overview of the subject, but he also attempts to explain some complex mathematics. In the 1996 edition of the book and subsequent editions, Hawking discusses the possibility of time travel and wormholes and explores the possibility of having a universe without a quantum singularity at the beginning of time.Early in 1983, Hawking first approached Simon Mitton, the editor in charge of astronomy books at Cambridge University Press, with his ideas for a popular book on cosmology. Mitton was doubtful about all the equations in the draft manuscript, which he felt would put off the buyers in airport bookshops that Hawking wished to reach. With some difficulty, he persuaded Hawking to drop all but one equation.[4] The author himself notes in the book's acknowledgements that he was warned that for every equation in the book, the readership would be halved, hence it includes only a single equation: E = mc2. The book does employ a number of complex models, diagrams, and other illustrations to detail some of the concepts it explores.

Acerca del autor (2015)

Stephen William Hawking was born in Oxford, England on January 8, 1942. He received a first class honors degree in natural science from Oxford University and a Ph.D. from Cambridge University. He was a theoretical physicist and has held the post of Lucasian Professor of Mathematics at Cambridge University from 1982 until his death. In 1974, he was elected a Fellow of the Royal Society, the world's oldest scientific organization. In 1963, he learned he had amyotrophic lateral sclerosis, a neuromuscular wasting disease also known as Lou Gehrig's disease. The disease confined him to a wheelchair and reduced his bodily control to the flexing of a finger and voluntary eye movements, but left his mental faculties untouched. He became a leader in exploring gravity and the properties of black holes. He wrote numerous books including A Brief History of Time: From the Big Bang to Black Holes, Black Holes and Baby Universes, On the Shoulders of Giants, A Briefer History of Time, The Universe in a Nutshell, The Grand Design, and Brief Answers to the Big Questions. In 1982, he was named a commander of the British Empire. A film about his life, The Theory of Everything, was released in 2014 and was based on his first wife Jane Hawking's book Traveling to Infinity: My Life with Stephen. He died on March 14, 2018 at the age of 76.
