Fritjof Capra brought the mystical implications of subatomic physics to popular consciousness for the very first time back in 1975. Many books have been written in the ensuing years about the connections between quantum theory and the ideas of Buddhism, Hinduism, and Taoism, but The Tao of Physics serves as the foundation on which the others have been built, and its wisdom has stood the test of time. Its publication in over twenty languages stands as testimony to its universal applicability and enduring significance. This special edition celebrates the fiftieth anniversary of the perennial classic and includes new material by the author--a preface, an updated afterword, and a postscript--reflecting on further discoveries and developments in the years since the book's initial publication.
