Summary

Summary

Twentieth-century physics was a long, strange trip indeed. Stranger still is what might lie ahead. In this startling book, science writer Tom Siegfried takes us into a weird world of quark nuggets, selectrons, quintessence, and quantum cosmology and introduces us to some of the most imaginative ideas being batted about by scientists today, from funny energy to mirror matter to two-timing universes. In addition, he reviews theories of the past both proven and unproven-offering us a grounding in our scientific history as well as an informed and intriguing look at the possibilities of tomorrow.

Booklist Review

There are three kinds of popular science book: the kind written by experts whose knowledge far exceeds their ability to tell an entertaining story; the kind written by experts who also happen to be terrific writers (Sagan, Gould); and the kind written by knowledgeable laypersons. This is the third kind. The author, science editor at the Dallas Morning News, is a journalist by trade, but he writes about science like a pro, making complex ideas seem straightforward. Witness his explanation of the mind-bending concept of "negative energy" (a vital aspect of quantum physics), which he equates to being in debt--when we spend more on credit than we earn, we not only don't have any money, we have "negative" dollars. There are lots of mind-bending ideas in here (a collapsing star goes from thousands of miles in diameter to about 20 miles in diameter in roughly a second), but nowhere does the author get bogged down in convoluted explanations or high-tech prose. A light, energetic introduction to cutting-edge physics and cosmology. --David Pitt


Publisher's Weekly Review

The universe, as physicists have come to know it, is a very strange place, filled with particles known as quarks. Space itself, physicists have come to understand, is curved, and there may well be more than the three spatial and one temporal dimensions we have become accustomed to. Making sense of these fascinating but complex ideas for the general reader is a difficult task, one that science journalist Siegfried (The Bit and the Pendulum) accomplishes deftly, with wit and insight. Siegfried attempts to provide answers to the two basic questions that absorb physicists today: "What is the universe made of?" and "How does the universe work?" Although his answers, like those of the physicists he writes about, are tentative and contingent on the next major discovery, Siegfried brings clarity and a great deal of enthusiasm to the search for understanding. He does a superb job of explaining how mathematical advances have led to an amazing array of "prediscoveries," from the existence of antimatter to the concept of an expanding universe. He also looks to the future and outlines numerous weird possibilities, from minuscule superstrings to parallel universes. Along the way, he presents a thoroughly engaging, if just a bit eclectic, history of physics. Siegfried has turned a difficult subject into a book that is difficult to put down. (Sept.)

Library Journal Review

Siegfried's title is a pun of sorts, referring both to strange matter, i.e., matter composed of up, down, and strange quarks as opposed to normal matter, composed of only up and down quarks, and perhaps also to some of the most recent nonstandard proposals of theoretical physicists and cosmologists. These include supersymmetry, string theory, various suggestions concerning the nature of the dark matter that seems to permeate the universe (and is hypothesized to explain gravitational forces), and multiplicities of dimensions going beyond the familiar three for space and one for time. Siegfried is a science journalist who has obviously devoted much time and thoughtful attention to discussions with the leading researchers in these esoteric areas. Without using mathematics, he has produced a very readable study that should give intelligent lay readers a good idea of what theorists are up to and why they are venturing into this remarkably challenging terrain.

Choice Review

Siegfried undertakes the intimidating challenge of explaining some of the toughest problems that physicists and astronomers currently are struggling to solve. Readers will explore a veritable zoo of weird particles, mirror matter, dark matter and energy, multiple universes, and more in the borderland between particle physics and cosmology. Many of these concepts seemed radical only a few years ago--and some still are. Siegfried (science editor, Dallas Morning News) does a good job of distinguishing between the two. This is basically an account of the quest for an understanding of the most fundamental nature of the physical universe. In most of the largely independent chapters, Siegfried begins with a historical perspective and quickly extrapolates to what the future-accepted paradigm might be. The introduction aptly calls the book "a guide to the pre-discoveries of the twentieth century." Expect a twisted, convoluted story, just like the real universe! Die-hard science buffs will find the book hard to put down. ^BSumming Up: Highly recommended. General readers; lower-division undergraduate through graduate students; two-year technical program students. T. D. Oswalt Florida Institute of Technology
