The concept of additional spatial dimensions is as far from intuitive as any idea can be. Indeed, although Harvard physicist Randall does a very nice job of explaining—often deftly through the use of creative analogies—how our universe may have many unseen dimensions, readers' heads are likely to be swimming by the end of the book. Randall works hard to make her astoundingly complex material understandable, providing a great deal of background for recent advances in string and supersymmetry theory. As coauthor of the two most important scientific papers on this topic, she's ideally suited to popularize the idea. What is absolutely clear is that physicists simply do not yet know if there are extra dimensions a fraction of a millimeter in size, dimensions of infinite size or only the dimensions we see. What's also clear is that the large hadron collider, the world's most powerful tool for studying subatomic particles, is likely to provide information permitting scientists to differentiate among these ideas soon after it begins operation in Switzerland in 2007. Randall brings much of the excitement of her field to life as she describes her quest to understand the structure of the universe. B&w illus.

Randall, a professor of physics at Harvard, offers a tour of current questions in particle physics, string theory, and cosmology, paying particular attention to the thesis that more physical dimensions exist than are usually acknowledged. Writing for a general audience, Randall is patient and kind: she encourages readers to skip around in the text, corrals mathematical equations in an appendix at the back, and starts off each chapter with an allegorical story, in a manner recalling the work of George Gamow. Although the subject itself is intractably difficult to follow, the exuberance of Randall's narration is appealing. She's honest about the limits of the known, and almost revels in the uncertainties that underlie her workincluding the possibility that some day it may all be proved wrong.

Our world apparently consists of more than the three spatial dimensions and the fourth dimension of time we are aware of according to Randall. Read morePublished 6 months ago by Randolph Eck
This book totally met my expectations. Ms Randall does a superb job relating other, unseen dimensions to our more narrow 3-dimensional world/ minds. Read morePublished 7 months ago by MJ Mc
