Book Description

27 April 1995
Paul Davies examines the consequences of Einstein's relativety theory, some 100 years after it was first put forward. Important though Einstein's theory turned out to be, it does not solve "the riddle of time". The search to find a unified field theory, or "Theory of Everything", remains at the top of the scientific agenda. When scientists began to explore the implications of Einstein's time for the universe as a whole, they made the discovery that time, and hence all of physical reality, must have a definite origin in the past. The origin of time is known today as the big bang. In this book, Davies recounts the struggles with the mysteries of time, black holes, time warps, time travel, the existence of God, the nature of the universe and the place of humans in the cosmos.

In this book Paul Davies provides a comprehensive, brilliant discussion of the nature of time. Beginning with Einstein's revolution which abolished the classical view of absolute time and space, Davies ranges widely into the scientific and philosophical ramifications of relativity. The bottom line is that our "common sense" notions of past, present, and future and our perception of time as flowng from present into future are distortions of reality. Instead of a flowing time that moves from present to future, time is actually a block of past, present, and future that is simply "there." The common sense notion of past, present, and future must be discarded if we are to understand the nature of time.Davies' discussion of time is exhaustive. And, while the book is difficult, particularly to a non-scientist like me, Davies has a gift for explaining very complex ideas in a way that a layperson can comprehend (but with effort; this is not casual reading!). Davies' prose is elegant and clear. He provides interesting insights into the lives of major scientific figures, particularly Einstein. And, he has a likable sense of humor. This book was a JOY TO READ.

4.0 out of 5 stars Comprehensive and informative 8 July 2002
By A Customer
Format:Paperback
Time has become a huge subject, particularly since Hawking set pen to paper, and raised the popular science bar. Davis's book shows just how many aspects of time can be considered, and how many unanswered questions remain after Einstein and others blew the concept apart early in the 20th century.
Each chapter is largely self-contained, is intelligent and accesible, and manages not to patronise - a flaw of so much of the popular science genre. The scientist biographies are there of course, as are the obligatory Feynman diagrams, but what sets this apart from similar books are the chapters on perception. "What time is now" is superbly thought-provoking, as it explores how our minds perceive each moment of time... novel and just a little frightening

As an A-level student I found this book a great insight into the world of theoretical physics - expressed in lay terms. It doesn't take a great deal of scientific knowledge to understand the principles that Davies tries to convey, making this a very enjoyable and fascinating read.
His explanations of Einstein's Special and General Theories of Relativity are concise and explained rigorously using conceivable scenarios. I enjoyed this very much and hope that others will enjoy this book as much as I did.

This is a masterpiece. I have read all of the relativity/time books by Hawking, Feynman, Rohrlich, etc., and this is the best by far. It is extremely easy to understand, plus Davies presents ideas that most authors leave out (such as Wheeler's single particle universe). If you have any interest in relativity or the nature of time, read this one.

4.0 out of 5 stars We still don't know what it is. 19 Nov 1998
By A Customer
Format:Paperback
If you've ever wondered what is time, where did it come from, does it flow, why does it seem to go in one direction, will it have an end, or is it slowing down, you'll not find your answers in Paul Davies' book "About Time." Neither are you likely to find your answers anywhere else. For me, the most profound knowledge that came from reading Davies' book is the reminder that we really don't know what time is. We live in it, experience it, but really - on a fundamental level - fail to comprehend it.
Davies has subtitled his book "Einstein's unfinished revolution," and he does an excellent job of exposing the reader to some of the unexpected (from a common-sense point of view) conclusions we draw about time from the special and general theories of relativity. He offers an interesting historical perspective on the life of Einstein, and how he developed his theories. Davies also provides some interesting background on experiments that have validated Einstein's space-time, reviewing the qualitative results from some of the more important experiments.
After this introduction to the non-universal time of relativity, Davies takes us to the ultimate time machine: black holes. He offers some interesting explanations about what an imaginary traveler to a black hole might see looking out, and how we - looking in - might view the hapless victim as she neared the event horizon.
As the book progresses, conclusions and examples become less and less concrete. Relative time is a proven fact, and most physicists consider black holes a foregone conclusion. From there, Davies takes us to the very root of some of the biggest issues in cosmology: the origin of time and the age of the universe.

4.0 out of 5 stars Brilliant - It really makes your head spin! 14 Jun 1999
By A Customer
Format:Paperback
My only criticism with this book is that the first chapter is a bit too long and philosopihical, so it takes a while to get into, but if you enjoy philosophy then it is not a problem, and if you don't then you can just skip it without losing any of the understanding of the theories that come later. He presents loads of different and amazing theories from different areas of physics and brings them all together near the end, and has one of the best explanations of the Twins Paradox and relativity that I have seen so far in a popular science book. It's impossible to put down, and your perspective of the universe will be completely different after reading it - it is amazing.
