"This is Frank Close's masterpiece — his best book, and one of the very best introductions to physics for the layperson. Close is a master expositor." — The (London) Sunday Times "Close's writing is beguiling, mingling personal and historical anecdote with carefully measured doses of exposition in such a way as to guide the reader painlessly into rather deep intellectual waters." — Nature "Life, intrinsically related to asymmetries, is the theme of this book, and Close offers us an absorbing and scientifically correct account of symmetry and its deep implications." — CERN Courier This thought-provoking work by a physicist and popular science writer explores the origins of asymmetry from the molecular level to that of the universe at large. Frank Close takes readers on a tour of asymmetry that ranges from the development of human embryos to the mysterious Higgs boson, or "God particle," and ongoing research at Switzerland's CERN laboratory.
