Promotional Information

This book explains, using diverse means, the quark model of the proton and neutron. It sketches the history of the quark idea and succeeds in explaining to nonphysicists why physicists believe in quarks even though a single quark has never been observed. I really like this book, which will serve important purposes. -- Gerald A. Miller, University of Washington

Reviews

Smith gives us a series of extremely readable and well-chosen analogies to explain the science. His relaxed style makes for an enjoyable read... [A] useful addition to the popular literature on particle physics. -- Alan Martin New Scientist Hidden Worlds is a satisfying account of the physics of quarks... Smith, a practicing nuclear physicist, conveys a clear picture of contemporary research and gives a well-articulated perspective from which to view modern nuclear and particle physics. Particularly noteworthy is the fine balance between the discussions of theory and experiment... Although the science background needed to understand the material is slight, this is a rather more sophisticated book than many popular accounts of modern physics... A thoughtful book for undergraduates or interested laypersons. Choice
