"I like this book: it is bold and strong; Professor 't Hooft has been a leader in the world of theoretical physics, and the knowledge and opinions he transmits are testaments of that. This book is great for students of physics and for well-seasoned researchers looking for a bigger picture....I applaud Professor 't Hooft for his willingness to write this provocative book." American Scientist
"The story is told with a confidence that comes only from deep understanding...gives the reader a sense of the exemplary, century-long cooperative effort that created the modern science of particle physics...it is easily accessible to the nonphysicist." New Scientist
"It gives a remarkable account of the interior dialogue of particle theory." Physics Today
"I recommend this book to professionals and some members of the general audience that have an interest in the concept of elementary particles as seen by the eyes of this author." Otto M. Friedrich, Jr., Science Books & Films
"Gerard t'Hooft has made outstanding contributions in theoretical particle physics, and if this attempt to explain his subject to a lay audience is a guide, he could become an excellent populariser, too....With analogies and anecdotes, t'Hooft skillfully enters the world of particles....the reader is now invited to enjoy t'Hooft's first-hand account of the great revolution in gauge theories in which he played such a singular role, culminating in his personal thoughts on string theory, black holes, and more." Frank Close
"...provides a lucid explanation of the motivations behind these theories and of their advantages and disadvantages, along with speculations about the possible form of a true theory of everything." Robert H. March, Physics Today
From 1960 until 1990 theoretical physicists and experimentalists worked together to probe deeper and deeper into the basic structure of matter. The author's involvement in the era enhances his account of one of the most exciting periods in the history of physics.
