Helen R. Quinn is professor emerita of particle physics and astrophysics at the Stanford Linear Accelerator Center at Stanford University. A member of the National Academy of Sciences, she is the coauthor of The Charm of Strange Quarks: Mysteries and Revolutions of Particle Physics. Yossi Nir is professor of physics at the Weizmann Institute of Science in Israel.

"Two distinguished physicists, Quinn and Nir trace in some detail both the history of modern particle physics and its relation to cosmology. Even though the text is free from equations, the authors clearly explain the details of the theories presented and their development. The logic and the meaning of the connections among the ideas make it interesting and challenging….This is a fine book that belongs in college libraries."---K. L. Schick, emeritus, Union College (NY), for, CHOICE --- "With the theme of a murder mystery installed in the reader by a silhouette on the cover, this book takes the reader on a tour de force of the case at hand. This book takes the reader on breathtaking foray into the depths of the particle that make-up our body and our worlds. And like an affable Dr. Watson, the reader can journey with [Helen Quinn and Yossi Nir] as they explore this still unsolved case." --- "For those curious about why the universe is the way it is, this book is a reminder of how much we have learned about physics at its smallest and largest scales, but also how much more we have yet to understand."---Jeff Foust, Space Review --- "In this page-turner, true science is written in the thrilling tone of science fiction. Quinn and Nir present the history of the antimatter problem and discuss its impact on our understanding of the cosmos--all without introducing a single equation or even a Greek letter. They reveal tantalizing possibilities for solving this puzzle, made possible by high-precision experiments that particle physicists like Quinn and Nir themselves undertake. For anyone wanting to know how physics works and physicists think, the writers make one of the greatest unsolved problems in physics both comprehensive and compelling." --- "[A] remarkable book which provides one of the most satisfying tours of particle physics I have ever read."---Marcus Chown, BBC Focus Magazine --- "[For] anyone wanting to know how physics works and physicists think, the writers have made a difficult topic comprehensible as well as compelling."---Joe Mielke, ForeWord Magazine --- "The standard model of particle physics is Quinn and Nir's arena for discussing one of its inadequacies: it has yet to answer why in the trillionths of a second after the big bang, there was a tiny numerical superiority of matter over antimatter; if there was not, atoms would not have formed. Addressing nonscientists, the authors describe the nature of this intriguing problem...[This book] will challenge yet reward readers with understanding of a fascinating subject at the frontier of science."---Gilbert Taylor, Booklist --- "Quinn and Nir have a daunting task explaining . . . one of the most active areas of theoretical physics today. If you like reading cosmologist Steven Hawking's A Brief History of Time, or particle physicist Brian Greene's The Elegant Universe, you will find The Mystery of the Missing Antimatter an absorbing scientific whodunit."---Laurence A. Marschall, Natural History --- "The big mystery about antimatter, as far as scientists are concerned, is why there isn't more of it in the universe. This is a serious and well-researched exposition of particle physics and cosmology that shows how science came upon antimatter and is now trying to understand the asymmetry between matter and antimatter. A nice feature is the occasional inclusion of personal recollections of the development of the standard model and of the scientists involved, which adds charm to the narrative. [O]ne of the best overviews...essential reading for students of physics who want to know what research in theoretical particle physics is doing."---Frank Close, Times Higher Education --- "Honorable Mention for the 2008 PROSE Award in Chemistry and Physics, Association of American Publishers"
