element in the theory. Therefore, “classical physics” includes the physics of Isaac Newton and relativity, both of which are structuredin this one-to-one manner. It does not, however, include quantum mechanics, which, as we shall see, is one of the things that makes quantum mechanics unique.
Be gentle with yourself as you read. This book contains many rich and multifaceted stories, all of which are heady (pun?) stuff. You cannot learn them all at once any more than you can learn the stories told in War and Peace, Crime and Punishment , and Les Misérables all at once. I suggest that you read this book for your pleasure, and not to learn what is in it. There is a complete index at the back of the book and a good table of contents in the front. Between the two of them, you can return to any subject that catches your interest. Moreover, by enjoying yourself, you probably will remember more than if you had set about to learn it all.
One last note; this is not a book about physics and eastern philosophies. Although the poetic framework of Wu Li is conducive to such comparisons, this book is about quantum physics and relativity. In the future I hope to write another book specifically about physics and Buddhism. In view of the eastern flavor of Wu Li , however, I have included in this book those similarities between eastern philosophies and physics that seemed to me so obvious and significant that I felt that I would be doing you a disservice if I did not mention them in passing.
Happy reading.

When I tell my friends that I study physics, they move their heads from side to side, they shake their hands at the wrist, and they whistle, “Whew! That’s difficult.” This universal reaction to the word “physics” is a wall that stands between what physicists do and what most people think they do. There is usually a big difference between the two.
Physicists themselves are partly to blame for this sad situation. Their shop talk sounds like advanced Greek, unless you are Greek or a physicist. When they are not talking to other physicists, physicists speak English. Ask them what they do, however, and they sound like the natives of Corfu again.
On the other hand, part of the blame is ours. Generally speaking, we have given up trying to understand what physicists (and biologists, etc.) really do. In this we do ourselves a disservice. These people are engaged in extremely interesting adventures that are not that difficult to understand. True, how they do what they do sometimes entails a technical explanation which, if you are not an expert, can produce an involuntary deep sleep. What physicists do, however, is actually quite simple. They wonder what the universe is really made of, how it works, what we are doing in it, and where it is going, if it is goinganyplace at all. In short, they do the same things that we do on starry nights when we look up at the vastness of the universe and feel overwhelmed by it and a part of it at the same time. That is what physicists really do, and the clever rascals get paid for doing it.
Unfortunately, when most people think of “physics,” they think of chalkboards covered with undecipherable symbols of an unknown mathematics. The fact is that physics is not mathematics. Physics, in essence, is simple wonder at the way things are and a divine (some call it compulsive) interest in how that is so. Mathematics is the tool of physics. Stripped of mathematics, physics becomes pure enchantment.
I had spoken often to a friend, who was a physicist, about the possibility of writing a book, unencumbered with technicalities and mathematics, to explain the exciting insights that motivate current physics. So when he invited me to a conference on physics that he and Michael Murphy were arranging at the Esalen Institute, I accepted with a purpose.
The Esalen Institute (it is named for an Indian tribe) is in northern California. The northern
