"In How to Build a Time Machine we start each chapter with an affirmation; ‘Yes, time travel is possible . . . ' There’s clarification, ‘ifs,’ often detailed historic references; consequences; and then the practicalities—at which point you might have the feeling that it’s not possible after all. But then there’s the ‘Or is it?’ and one cannot but take the bait and turn the page (loop). To name but a few, what does the following have to do with time-travel?: near-light speed travel; an infinitely long cylinder built from dust—or a less ambitious one (!) built from Neutron stars; Wormholes; Paradoxes; Black/White Holes; Antimatter; Dark Energy . . . ? If you’re like me when presented with such a list—appetite whet to the point of drooling—this is a book written with you in mind! One last and very important point: Clegg is both a writer and a Physicist; and it’s as a writer—one who is able to communicate physics to the non-specialist—and that makes this book so very enjoyable. The hard stuff is there; between the lines; but we’re not asked to deal with it—Clegg leads us through, in his own imitable style! There are just two equations: Einstein’s E=MC2 (of course!), and Maxwell’s—the latter because they’re so 'beautifully spare and simple looking.' Perfect."—Dr. Peet Morris, Oxford University "Here's the book the science reading community's been waiting for . . . The resulting vision will tantalize your instinct."—San Francisco Book Review "A solid overview of some of the quirkier corners of physics, with an entertaining connection to pop culture."—Kirkus Reviews
"With an eye to making science interesting and understandable, Clegg continues to craft accessible works out of difficult topics, in this case the nature of time . . . Clegg reminds us of how much humans have accomplished in the science so far and of the many things once thought unimaginable that are now part of everyday life. An engaging read, highly recommended . . . Clegg excels at making science accessible."—Rachel M. Minkin, Michigan State University Libraries, Lansing, Library Journal
