5.0 out of 5 stars How does a single electron pass through two slits at the same time? It must move discontinuously..., 23 May 2007
This review is from: The Elegant Universe: Superstrings, Hidden Dimensions and the Quest for the Ultimate Theory (Paperback)
Greene gave a very popular introduction of the mysterious quantum world. His H-Bar is an ingenious pun. However, his explanation of Feynman's path integral was wrong. Maybe he inherited from Hawking. The paths in Feynman's approach are purely quantum states, not classical continuous paths at all, as Greene depicted in his book. Nor did Feynman claim that his method implied such a bizarre picture.

However, a single electron does pass through two slits at the same time in the double-slit experiment. But how does it pass through two slits at the same time? Nobody knew. In fact, it seems very evident that the single electron can only pass through the two slits at the same time in a discontinuous way. Therefore, its motion may be not continuous but discontinuous. To our surprise, such discontinuous motion is imaginable and comprehensible. This intriguing idea has actually been lucidly expounded in a recent book Quantum Motion - Unveiling the Mysterious Quantum World. A more popular introduction can be found at my name.

Once we realize that motion is discontinuous and random in reality, we may finally understand the mysterious quantum world, where an electron can pass through two slits at the same time.

All very interesting, but says next to nothing about the book.
