"This is a complete comprehensive textbook of all areas of classical and relativistic Physics including mechanics, E & M, quantum theory, perturbation, solid state, and particle physics. ... It is good enough to be read cover to cover and will not disappoint the reader reviewer. I highly recommend this book for physics students, and investigators in physics theories." (Joseph J. Grenier, Amazon.com, January, 2016) "This is a splendid and very comprehensive review of the special and general theories of relativity and their applications, in a collection of about 40 articles by experts in the field. ... the book will appeal to a wide variety of readers, from advanced undergraduates to experts in the field. ... I doubt that there is any physicist who would not find something new and interesting here." (Alan Heavens, The Observatory, Vol. 135 (1245), April, 2015)
