"In this fascinating and accessible book, physicist Victor J. Stenger guides the lay reader through the key developments of quantum mechanics and the debate over its apparent paradoxes. In the process, he critically appraises recent metaphysical fads popularized by such authors as Deepak Chopra and Fritjof Capra. Dr. Stenger's knack for elucidating scientific ideas and controversies in language that the nonspecialist can comprehend opens up to the widest possible audience a wealth of information on the most important findings of contemporary physics." "Stenger makes it clear that current scientific hypotheses about the material nature of reality are all we need to explain the available evidence and that mystical notions say more about the human need to believe than about the fundamental makeup of the universe."--BOOK JACKET.
