A Brief History of Time attempts to explain a range of subjects in cosmology, including the Big Bang, black holes and light cones, to the nonspecialist reader. Its main goal is to give an overview ofthe subject but, unusual for a popular science book, it also attempts to explain some complex mathematics. The 1996 edition of the book and subsequent editions discuss the possibility of time traveland wormholes and explore the possibility of having a universe without a quantum singularity at the beginning of time.
The author notes that an editor warned him that for every equation in the bookthe readership would be halved, hence it includes only a single equation: E = mc2. Early in 1983, Hawking 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 toreach. It was with some difficulty that he persuaded Hawking to drop all but one equation.[4] In addition to Hawking's notable abstention from presenting equations, the book also simplifies mattersby means of illustrations throughout the text, depicting complex models and diagrams.
[edit]Editions

1988: First edition. It included an Introduction by Carl Sagan that tells the following story:Sagan was in London for a scientific conference in 1974, and between sessions he wandered into a different room, where a larger meeting was taking place. "I realized that I was watching an ancientceremony: the investiture of new fellows into the Royal Society, one of the most ancient scholarly organizations on the planet. In the front row, a young man in a wheelchair was, very slowly, signing hisname in a book that bore on its earliest pages the signature of Isaac Newton... Stephen Hawking was a legend even then." In his Introduction, Sagan goes on to add that Hawking is the "worthy...
