"According to this new theory, and electron moving between orbits would disappear from one and reappear instantaneously in another without visiting the space in between. "This idea -the famous "quantum leap"- is of course utterly strange, but it was too good not to be true."

"It seemed as if there was no end to strangeness. As physicists delved deeper, they realized they had found a world where not only could electrons jump from one orbit to another without travelling across any intervening space, but matter could pop into existance from nothing ar all-"provided", in words of Alan Lightman of MIT, "it disappears again with sufficient haste"

(This is a passage from "A Short History of Nearly Everthing" by Bill Bryson.
It is written for persons like me, with no scientific education whatsoever. But it reads like a novel and do I understand right from these two quoted parts that quantum leaps refer to both micro and macro? )

Things I never knew of but vaguely now prove to be really very interesting.
