5.0 out of 5 stars
A very clear explanation of physics for the layman, June 16, 2000
Unfortunately, the first book by Gary Zukav that I read was 'Seat of the Soul.' That was a mistake. I was disappointed because he offered no background, or justification, or source for his ideas. he simply laid them out pedantically, as fait accompli. This book is much better. I can see why it achieved critical acclaim. It is a clear attempt to explain physics to the layman in terms that he will understand. It still has some faults, but generally he does an excellent job. Well, maybe not faults--just misplaced emphasis. For example, he goes on at great length explaining the connection between wavelength and frequency and amplitude, charting them and talking them to death, although they are very simple, easy to understand concepts. He does the same thing with three-dimensional coordinates. But, when he comes to difficult material to grasp, he often slides into incomprehensible language, for example: "In a quantum mechanical experiment, the observed system, traveling undisturbed between the region of preparation and the region of measurement, develops according to the Schrodinger wave equation. During this time, all of the allowed things that could happen to it unfold as a developing wave function. However, as soon as it interacts with a measuring device (the observing system), one of those possibilities actualizes and the rest cease to exist. The quantum leap is from a multifaceted potentiality to a single actuality." (Page 75). Pretty turgid prose. What he is talking about is the firing of a photon through a shield with two slits in it, at a wall where the hits were registered. Much of the book could have been written in far simpler terminology, while approximating the activity discussed in more intelligible terms for the layman. However, that said, Zukav does a good job of explaining some very difficult material. Probably the scientists whom he ran the manuscript by contributed to the confusion by insisting on language more precise than was needed in order to get the ideas across. He does manage to express the mysteries uncovered by high-energy physicists, and the tendency of quantum mechanics, more and more, to resemble statements made hundreds of years ago by the Eastern mystics. I recommend this book, and have no difficulty assigning it five stars. Joseph Pierre, Author of The Road to Damascus: Our Journey Through Eternity
