Overview

"""Bucky Fuller thought big,"" Wired magazine recently noted, ""Arthur C. Clarke thinks big, but Cliff Pickover outdoes them both."" In his newest book, Cliff Pickover outdoes even himself, probing a mystery that has baffled mystics, philosophers, and scientists throughout history--What is the nature of time? In Time: A Traveler's Guide, Pickover takes readers to the forefront of science as he illuminates the most mysterious phenomenon in the universe--time itself. Is time travel possible? Is time real? Does it flow in one direction only? Does it have a beginning and an end? What is eternity? Pickover's book offers a stimulating blend of Chopin, philosophy, Einstein, and modern physics, spiced with diverting side-trips to such topics as the history of clocks, the nature of free will, and the reason gold glitters. Numerous diagrams ensure readers will have no trouble following along. By the time we finish this book, we understand a wide variety of scientific concepts pertaining to time. And most important, we will understand that time travel is, indeed, possible."

A playful introduction to modern physics from a Discovery magazine columnist. Pickover frames his discussion of time in a didactic science-fictional tale (told somewhat clumsily in the second person) set a few decades in the future and featuring an alien philosopher named Mr. Veil, who is your assistant at the Museum of Music. In order to travel backward in time to enjoy the piano playing of Chopin (whose music functions as a leitmotif here), you must instruct Veil in the nature of time and space, particularly Einstein's Relativity Theory. Veil performs simple experiments using futuristic hardware to demonstrate the key issues: the subjective nature of now, the flexibility of time and space in systems in motion relative to one another, and the speed of light as an invariable. After each brief chunk of story, the text steps back to examine the science behind the science fiction in a more straightforwardly didactic manner. Pickover encourages the reader to approach the material in an interactive way, offering computer programs (in BASIC) to calculate some of the quantities discussed. Frequent references to popular sci-fi movies and stories make the concepts even more accessible to readers. After the by-now well-worn subject of relativity is sufficiently explained, the latter chapters discuss the possibility of real time travel, using such speculative techniques as wormholes (caused by the enormous gravitation of black holes) and giant rotating cylinders. Along the way, Pickover looks at the broader philosophical implications of time travel, especially in relation to the paradoxes involving causality and the immutability of the past. While much of this is familiar to sci-fi fans and followers of popular science, the basic principles are clearly explained, and the shift from the framing story to straight exposition is not too abrupt. In spite of the overly cute narrative form, this could serve as an entertaining introduction to modern scientific principles for bright students as well as adults. (Kirkus Reviews)

There are several good books about the physics of time travel, which (surprisingly) is not forbidden by the laws of physics as understood today. Pickover's variation on the theme is entertaining and accessible, and chiefly distinguished by including a few short computer programs which can be used to demonstrate some of the things he describes. It is positively naughty of the author, though, not to include in his references either John Gribbin's In Search of the Edge of Time or Kip Thorne's Black Holes and Time Warps, which cover very similar ground and which he must have read. If you already have either of those books, you don't need this one; if you haven't, this is as good an introduction to the subject as they are. (Kirkus UK)
