Barry Parker's books reliably make the abstract engaging and the complex accessible. -- Dr. E.C. Krupp, Director, Griffith Observatory, Los Angeles "An excellent book. . . . It captures Einstein's deep insight into the mysteries of space and time. The clarity of Parker's writing style, creative use of illustrations, and humorous cartoons make the topics of black holes, cosmology, and quantum mechanics easy to comprehend. I highly recommend this captivating book for both the nonscientist and scientist." -- Robert L. Zimmerman, Institute of Theoretical Science, University of Oregon "Stimulating! . . . In this book, Parker has achieved an enjoyable, well-thought-out blend of Einstein's personal history along with his most notable scientific achievements which have revolutionized our concepts of space and time, gravity, and the structure of stars and the universe." -- Dr. V. Gordon Lind, Physics Department, Utah State University "Excellent. . . . This book preserves the integrity of Einstein's theories and makes their ideas accessible and comprehensible. . . . It was a joy to learn as much about Einstein and his life as I did about his ideas. This book also clears up a few minconceptions about Einstein. . . . An interesting, well-written narrative of the essence of modern physics and how it came to be." -- Dr. J. Ward Moody, Department of Physics and Astronomy, Brigham Young University
