This thorough introduction to Einstein's special theory of relativity is suitable for anyone with a minimum of one year of undergraduate physics with calculus. The authors cover every aspect of special relativity, including the impact of special relativity in quantum theory, with an introduction to relativistic quantum mechanics and quantum field theory. They also discuss the group theory of the Lorentz group, supersymmetry, and such cutting-edge topics as general relativity, the standard model of elementary particles and its extensions, and superstring theory, giving a survey of important unsolved problems. The book is accompanied by an interactive CD-ROM illustrating classic problems in relativity involving motion.
