Description de l’éditeur
"Bucky Fuller thought big," Wired magazine recently noted, "Arthur C. Clarke thinks big, but Cliff Pickover outdoes them both." And now, 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? These are questions that Pickover tackles in this 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. Pickover includes numerous diagrams so readers have no trouble following along, computer code that lets us write simulations for various aspects of time travel, and an on-going science fiction tale featuring quirky characters who yearn to travel back in time to hear Chopin play in person. By the time we finish this book, we understand such seemingly arcane concepts as space-time diagrams, light cones, cosmic moment lines, transcendent infinite speeds, Lorentz transformations, superluminal and ultraluminal motions, ninkowskian space-times, Godel universes, closed timelike curves, and Tipler cylinders.
And most important, we will understand that time travel need not be confined to myth, science fiction, Hollywood fantasies, or scientific speculation. Time travel, we will realize, is possible.
PUBLISHERS WEEKLY
If you thought time travel was just for science fiction nuts, think again. As Pickover (Black Holes: A Traveler's Guide) demonstrates, time travel is not the stuff of Asimovian dreams, it being theoretically possible. Of course, how to travel through time is no simple matter, nor is explaining it, but Pickover rises to the challenge in many ways. Witty and profound quotations--from Einstein to Woody Allen--about time and our relationship to it are liberally scattered throughout. Pickover's masterstroke, however, is to divide each chapter into two sections. The first is a second-person narration recording the impromptu discussions about time-travel of a Chopin-obsessed curator from a Museum of Music with his assistant, "a Zetamorph, a member of a race of philosophers from a subterranean air pocket on Ganymede, a moon of Jupiter" and with a female earthling student. The second section, dutifully labeled "The Science behind the Science Fiction," is a sober essayistic review of topics addressed in the narrative half. Despite the popular tone, Pickover does not shy away from the mathematics of time travel. (He even includes an appendix of programmable algorithms.) A careful reader with some basic science should be able to follow Pickover chapter by chapter (and truthfully, some of the formulas can be skimmed). The imaginative and humorous approach makes a difficult subject palatable--and gives a plug for Chopin at the same time.
