Michio Kaku is a professor of physics at the City University of New York, cofounder of string field theory, and the author of several widely acclaimed science books, including Hyperspace, Beyond Einstein, Physics of the Impossible, and Physics of the Future. He is the science correspondent for CBS's This Morning and host of the radio programs Science Fantastic and Explorations in Science. Jennifer Trainer Thompson is a writer and the coeditor with Michio Kaku of Nuclear Power: Both Sides, which The Christian Science Monitor selected as one of the best books of 1982. Her other books include Hot Licks: Great Recipes for Making and Cooking with Hot Sauces, The Yachting Cookbook (coauthored with Elizabeth Wheeler), Trail of Flame, Jump Up and Kiss Me, and The Great Hot Sauce Book. Her articles on science, culture, travel, and foo have appeared in many publications, including The New York Times, Travel & Leisure, and Omni.
Recently, the ``superstring'' theory, which asserts that all physical matter consists of extraordinarily minute vibrating strings, has been touted as the route to the long-sought unified theory of forces; some proponents call it a ``theory of the universe'' that will bring fundamental physics research to a closure. The first author of the present book is a researcher in the field who offers here one of the earliest superstring presentations for lay readers. The beginning chapters offer a not-very-good history of early 20th century physics, but the remainder of the work becomes livelier and more convincing as it approaches Dr. Kaku's own area of expertise. On the whole this is a fairly successful introduction to a new and exciting scientific area. Jack W. Weigel, Univ. of Michigan Lib., Ann Arbor
