Einstein’s Mirror is a book on relativity with a difference. Following the successful format of their earlier book, The Quantum Universe, the authors blend a simple, non-mathematical account of the underlying theory of special relativity and gravitation with a description of the way these theories have been triumphantly supported by experiment. Applications of relativity in atomic and nuclear physics are wide-ranging, from satellite navigation systems, particle accelerators and nuclear power to quantum chemistry, anti-matter and black holes. The text is enlivened by a superb collection of photographs and by amusing anecdotes about the early pioneers. The closing chapter examines the influence of Einstein’s relativity on the development of science fiction. Final year students at school, general readers with an interest in science, and undergraduates in science subjects will all enjoy and benefit from this fascinating and accessible introduction to one of the most profound scientific discoveries of the twentieth century.
