But I do not know what you mean by orbits “falling into the nucleus.” Surely we are agreed that even the kinematics of quantum theory is wholly different from that of classical mechanics (the hν relation!). I therefore see no geometrically intelligible or controllable meaning in the notion of “falling into the nucleus.” It is, in fact, my sincere conviction that any interpretation of the Rydberg formula in terms of circular or elliptical orbits within classical geometry possesses not the slightest physical significance, and my entire pitiful effort is directed at exterminating the concept of orbits – after all, they cannot be… Πηγή
