Product Description
Amazon.co.uk Review
The thought that humans might one day be able to harness time, travelling freely from one age to another, has been a fixture of science fiction for years. Science fact is beginning to catch up to the long-held dream: in this entertaining survey, researcher-writer Clifford Pickover observes that current theories of physics support--or at least do not rule out--the possibilities of time travel.
In chapters that mix whimsical science-fiction scenarios with brief essays on matters of fact, Pickover takes a leisurely stroll through various chrono-cosmological theories and discusses their attendant virtues, flaws, and inherent paradoxes. One modern notion, Kurt Gödel's addendum to Albert Einstein's general theory of relativity, posits a rotating universe in which it is possible for a traveller to move between states of time and return to the present (assuming, of course, that there is such a thing as the present); the theory depends on a universe that rotates slowly, which seems not to be the case, but, as Pickover points out, it nevertheless provides a mathematical basis for time travel--which, he suggests, is a fine and worthy start. Pickover peppers his well-illustrated text with learned asides on such matters as light-cone diagrams, rocket clocks, string theory, parallel universes and other topics real and speculative. What he turns up in the course of his narrative is fascinating--and fuel for anyone who entertains dreams of inter-dimensional wandering. --Gregory McNamee
Review
"Pickover...stretches the limits of computers, art, and thought."--Los Angeles Times
"Only Clifford Pickover would think of mixing time travel and music. Gripping, clear -- this book could well be his best yet! A must buy for all wannabe time travelers."-- Ian Stewart, Scientific American
"The irrepressible and prolific Clifford Pickover... romps joyously through at least four perfectly respectable scientific routes to time travel: relatively, particle physics, quantum mechanics and psychology."--New Scientist
"How to travel through time is no simple matter, nor is explaining it, but Pickover rises to the challenge in many ways....The imaginative and humorous approach makes a difficult subject palatable."--Publishers Weekly

I find this subject facinating and this book really does add to my facination. Even though the science of the subject may be quiet dense, Pickover manages to present it in a way where everyone can understand the concept of time travel .A book that puts you thinking for sure.

If you lost the faith, you are a few pages from finding it!
20 April 2000
Format:Hardcover
I am completely sure that every kind of reader will get pleasure from this book; furthermore, I guarantee that any reader will recover his/her lost faith in time travel. If you saw "Contact" (the movie), or you often read science-fiction novels or even if you just want to enjoy a good and productive reading, you are strongly advised to buy and read this excellent and fascinating book. "Time: A Traveler's Guide" was written in the same clear, precise and funny way as "Black Holes: A Traveler's Guide" was done in its opportunity. The book now featured by Dr. Pickover will let you discover the "science behind the science-fiction" about the main topic by means of a science-fiction story plenty of funny dialogs, diagrams, formulas and graphics that make the information, and the book in general, a delight to read. You will NOT need vast knowledge in physics or mathematics to understand the ideas, and furthermore, to realize that time travel is possible. The book also offers a great deal of information about the special and the general theory of relativity besides spacetime physics. I also recommend Pickover's book about Black Holes as an excellent complement because that book is one of the best text in this topic and you will see that black holes could serve (in a far but possible future) to travel through time. Sincerely, buy the book and you will see that every page you read becomes a piece of your renovated faith in a dream as beautiful as paradoxical, TIME TRAVEL!

Is your brain a time machine?
5 Jun 1999
Format:Hardcover
This was written after Black Holes, A Traveller's Guide and follows exactly the same format. The story was not quite as good, but the subject matter of the book was more interesting and relevant to everyday experience (at least for techies) , particularly the chapter on The Brain's Time Machine. The brain compensates for delay loops in the human body's operating system, and knowing how these work enables experiments to be performed that make it look as though people can see short periods into the future.

Quantum Physics Can Be Fun
10 April 2004
Format:Paperback
An outstanding book - I have never before read a book that dealt with such advanced concepts that was so easy to read and comprehend and as hard to put down (I read it in a weekend). Dr. Pickover's style of making the first half of each chapter a sci-fi story, with the second half "the science behind the story" makes this book fun and teaches you without having to work. Definately inspires creative thought.
I have a few more Pickover books on order and look forward to more. (...)
