The second edition of this well-received book is a clear and readable introduction to the ideas and concepts of particle physics. It bridges the gap between traditional textbooks on the subject and popular accounts that assume little or no background in the physical sciences on the part of the reader. This edition has been carefully revised throughout to provide a completely up-to-date and comprehensive overview of this fascinating subject. Historical aspects are discussed together with the most important recent experiments, and the theoretical development of the subject is traced from its foundations in relativity and quantum mechanics through to the very latest theories. There are also three completely new chapters covering quantum gravity, super-unification, and the relationship between particle physics and cosmology. Read Less
