Q: How can electrons “jump” between places without covering the intervening distance?
A standing wave (like a guitar string, or an electron orbital) usually has “nodes” where the wave is always zero. But of course there’s a big difference between the wave being zero at a node, and the wave being unable to get to the other side of that node. One of my personal fave examples of “large scale” quantum weirdness is microwave ovens. A microwave oven creates a standing wave of photons with a “plus-shaped” (+) node, which leaves the center of the chamber especially cold. So thinking of things like electrons as particles leads to incorrect conclusions.
