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.

Physicist Lee Smolin On Einstein's Unfinished Revolution in Quantum Physics: Author Q&A

I have never fully grasped just what the Theory of Relativity is about, so areas of this book are virtually wasted on me. Undoubtedly it was a revolution in our sense of time, but it seems also to have left a new set of riddles. How did time itself begin? Why has it a definite direction, and can this be reversed? Is "time travel" mere fantasy, or is it factually possible? Much of Paul Davies's book is in question and answer form, but he is not "writing down" and some of his arguments, often supported by diagrams, need concentrated reading. All this is not helped by a small and rather ugly type face.

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.

A computer-generated artwork inspired by quantum mechanics. Credit: Getty. Quantum mechanics is perhaps the most successful theory ever formulated. For almost 90 years, experimenters have subjected it to rigorous tests, none of which has called its foundations into question. It is one of the triumphs of twentieth-century science. In this challenging book, he attempts to examine other options for a theory of the atomic world. Smolin is a theoretical physicist at the Perimeter Institute in Waterloo, Canada, and an outspoken critic of the direction his subject has taken over the past four decades.
