The Force of Symmetry gives an elementary introduction to the spectacular interplay between the three great themes of contemporary physics: quantum behaviour; relativity; and symmetry. In clear, non-technical language, though without oversimplification, it explores many fascinating aspects of modern physics, discussing the nature and interaction of force and matter. All these themes are drawn together, towards the end of the book, to describe the most successful physics theory in history, the 'standard model' of subatomic particles. The lively and non-technical approach of this book will make it suitable for first-year undergraduates in the physical sciences and mathematics, or even to those just about to embark on such courses. It will also be a valuable accompaniment to more advanced texts on quantum mechanics and particle physics.
Every scientific fact begins as an opinion about the unknown?a theory?that becomes fact as evidence piles up to support it. But what if two theories exist that correspond perfectly to observed phenome
