About Time: Einsteins Unfinished Revolution by Paul Davies

An elegant, witty, and engaging exploration of the riddle of time, which examines the consequences of Einsteins theory of relativity and offers startling suggestions about what recent research may reveal.
The eternal questions of science and religion were profoundly recast by Einsteins theory of relativity and its implications that time can be warped by motion and gravitation, and that it cannot be meaningfully divided into past, present, and future.
In About Time, Paul Davies discusses the big bang theory, chaos theory, and the recent discovery that the universe appears to be younger than some of the objects in it, concluding that Einsteins theory provides only an incomplete understanding of the nature of time. Davies explores unanswered questions such as:
* Does the universe have a beginning and an end?
* Is the passage of time merely an illusion?
* Is it possible to travel backward -- or forward -- in time?
About Time weaves physics and metaphysics in a provocative contemplation of time and the universe.

When Albert Einstein formulated his theory of relativity it brought about a revolution in our understanding of time, yet also presented a new set of mysteries. Einstein's time can be warped, leading to bizarre possibilities such as black holes and time travel, while making a nonsense of our perception of a 'now' or a division of time into past, present and future. He gives straightforward descriptions of topics such as the theory of relativity, the relation between time dilation and the speed of light and Hawking's 'imaginary time'. He concludes that, despite decades of progress in unravelling the mysteries of time, the revolution is still underway Price Search in Elephant: Search.

Thank you! In a long ramble interspersed with biographical digressions, personal reflections, and questions from a hypothetical ""skeptic"" baffled by the quantum world, Davies discourses on concepts of time embodied in ancient cultural and religious beliefs; the Newtonian clockwork universe, in which time flows according to unbending mathematical laws; Einstein's theory that time is relative and flexible; and nonintuitive ideas from quantum mechanics. In this light, he interprets the history of human intellectual development. There have been revolutionary changes, he notes, but the story is far from over. Davies is energized by the notion that nature is permissive -- that just about anything can happen if it is not forbidden by a physical law.

In About Time: Einstein's Unfinished Revolution Paul Davies confronts the puzzles and paradoxes of time that have bemused the world's greatest thinkers throughout the ages. When Albert Einstein formulated his theory of relativity it brought about a revolution in our understanding of time, yet also presented a new set of mysteries. Einstein's time can be warped, leading to bizarre possibilities such as black holes and time travel, while making a nonsense of our perception of a 'now' or a division of time into past, present and future. In About Time Paul Davies tackles the tough questions about time, including the strange relationship between physical time and our psychological perception of it. He gives straightforward descriptions of topics such as the theory of relativity, the relation between time dilation and the speed of light and Hawking's 'imaginary time'. He concludes that, despite decades of progress in unravelling the mysteries of time, the revolution is still underway Writing with passion and wit, he lets his scientific message shine through' - New Statesman.
