A Brief History of Time-Stephen Hawking

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 of the 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 travel and 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 book the 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 to reach. 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 matters by means of illustrations throughout the text, depicting.

The Meaning of Relativity - Albert Eistein

in 1921, five years after the appearance of his comprehensive paper on general relativity and twelve years before he left Europe permanently to join the Institute for Advanced Study, Albert Einstein visited Princeton University, where he delivered the Stafford Little Lectures for that year. These four lectures constituted an overview of his then controversial theory of relativity. Princeton University Press made the lectures available under the title The Meaning of Relativity, the first book by Einstein to be produced by an American publisher. As subsequent editions were brought out by the Press, Einstein included new material amplifying the theory. A revised version of the appendix "Relativistic Theory of the Non-Symmetric Field," added to the posthumous edition of 1956, was Einstein's last scientific paper.

Review:

"A condensed unified presentation intended for one who has already gone through a standard text and digested the mechanics of tensor theory and the physical basis of relativity. Einstein's little book then serves as an excellent tying-together of loose ends and as a broad survey of the subject."--Physics Today

The God Delusion Richard Dawkins Free Download

The God Delusion is a 2006 bestselling^[1] non-fiction book by English biologist Richard Dawkins, professorial fellow of New College, Oxford,^[2][3] and inaugural holder of the Charles Simonyi Chair for the Public Understanding of Science at the University of Oxford.

In The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that belief in a personal god qualifies as a delusion, which he defines as a persistent false belief held in the face of strong contradictory evidence. He is sympathetic to Robert Pirsig's statement in Lila that "when one person suffers from a delusion it is called insanity. When many people suffer from a delusion it is called religion".^[4]

As of January 2010, the English version of The God Delusion had sold over 2 million copies.^[5] It was ranked No.2 on the Amazon.com bestsellers' list in November 2006.^[6][7] In early December 2006, it reached No.4 in the New York Times Hardcover Nonfiction Best Seller list after nine weeks on the list.^[8] It remained on the list for 51 weeks until 30 September 2007.^[9] The German version, entitled Der Gotteswahn, had sold over 260,000 copies as of 28 January 2010.
