How does each electron pass through two slits at the same time? It must move discontinuously...,

It is a pity that Hawking only used several pages to explain the mysterious quantum world. Especially, his explanation of Feynman's path integral approach was misleading. The paths in Feynman's approach are not classical continuous paths at all, as Hawking depicted in his book. They are also quantum states.
However, Hawking's claim that each single electron must pass through two slits at the same time is right. But how does a single electron pass through two slits at the same time? It is well known that Hawking preferred many worlds theory, but he didn't refer to it in the book. In fact, it seems evident that the single electron can only pass through the two slits at the same time in a discontinuous way. Therefore, its motion must be not continuous but discontinuous. Such discontinuous motion is imaginable and comprehensible. It 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.
