First printing of these importent papers on the philosophy of Quantum physics. "If we have to go on with these damned quantum jumps, then I'm sorry that I ever got involved." (E.Schrodinger)."In it he contrasts the smooth evolution of the Schrodinger wavefunction with the erratic behaviour of the picture by which the wavefunction is usually supplemented, or 'interpreted', in the minds of most physicists. He objects in particular to the notion of 'stationary states', and above all to 'quantum jumping' between those states. He regards these concepts as hangovers from the old Bohr quantum theory, of 1913, and entirely unmotivated by anything in the mathematics of the new theory of 1926. (J.S. Bell).

FIRST PRINTINGS: THE VERY RARE ORIGINAL OFFPRINT AND THE ORIGINAL ISSUES IN THE RARE WRAPPERS of Schrödinger's consideration of quantum jumps and the future of physics. "Throughout his life, Schrödinger sought to discredit Bohr's concept of quantum jumping. His forceful attacks culminated in the 1952 paper 'Are There Quantum Jumps?' In this paper he also presented some objections against Born's collision treatment and probabilistic interpretation." Schrödinger also "repeated his old arguments, enveloped in a good deal of rhetoric. Physical science is at present in danger, he argued, of being severed both from its glorious history and from its cultural milieu. Physicists must concern themselves, not only with ingenious theoretical constructs and their agreement with experimental data, but also with the suitability of their concepts to be absorbed into a general spiritual culture of mankind: 'Science is not a soliloquy. It gains value only within its cultural milieu, only by having contact with all those who are now, and who in future will be, engaged in promoting spiritual culture and knowledge.' "Not all concepts, according to Schrödinger, are destined to survive: 'A theoretical science. where the initiated continue musing to each other in terms that are, at best, understood by a small group of close fellow travelers, will necessarily be cut off from the rest of cultural mankind, in the long run it is bound to atrophy and ossify'. The 'abbreviated language' of quantum jumps, Schrödinger argued, is not a suitable candidate for long-term survival. There were other 'ingenious constructs of the human mind that gave an exceedingly accurate description of observed facts and have yet lost all interest except to historian,' for example, the epicycles of planetary motion. The modern analogue of epicycles, Schrödinger prophesied, are the quantum jumps" (Beller, Quantum Dialogue: The Making of a Revolution).
