quantum-jump is master-signifier

At the invitation of Bohr, Schrödinger visited Copenhagen in September, 1926, to lecture on wave mechanics. Long discussions, lasting several days, then took place concerning the foundations of quantum theory, in which Schrödinger was able to give a convincing picture of the new simple ideas of wave mechanics, while Bohr explained to him that not even Planck’s Law could be understood without the quantum jumps.
— “If we are going to stick to this damned quantum-jumping, then I regret that I ever had anything to do with quantum theory,” Schrödinger exclaimed finally in despair, to which Bohr replied:
— “But the rest of us are thankful that you did, because you have contributed so much to the clarification of the quantum theory.”

(Heisenberg, 1955, tribute book for the 70th birthday of Niels Bohr)
