Wolfgang Pauli: News

“It is always the older that emanates the new one.”

Wolfgang Pauli

Letter to Markus Fierz (13 October 1951)

“Nevertheless, there remains still in the new kind of theory an objective reality, inasmuch as these theories deny any possibility for the observer to influence the result of a measurement, once the experimental arrangement is chosen.”

Context: In the new pattern of thought we do not assume any longer the detached observer, occurring in the idealizations of this classical type of theory, but an observer who by his indeterminable effects creates a new situation, theoretically described as a new state of the observed system. In this way every observation is a singling out of a particular factual result, here and now, from the theoretical possibilities, therefore making obvious the discontinuous aspect of physical phenomena.
Nevertheless, there remains still in the new kind of theory an objective reality, inasmuch as these theories deny any possibility for the observer to influence the result of a measurement, once the experimental arrangement is chosen. Therefore particular qualities of an individual observer do not enter into the conceptual framework of the theory.

“The layman always means, when he says "reality" that he is speaking of something self-evidently known; whereas to me it seems the most important and exceedingly difficult task of our time is to work on the construction of a new idea of reality.”

“Against all the retrogressive endeavors (Bohm, Schrödinger etc. and in some sense also Einstein) I am sure that the statistical character of the ψ-function and hence of nature’s laws – on which you insisted from the very beginning against Schrödinger’s resistance – will define the style of the laws at least for some centuries. It may be that later, e. g. in connection with the living processes, one will find something entirely new, but to dream of a way back, back to the classical style of Newton-Maxwell (and these are just dreams these gentlemen are giving themselves up to) seems to me hopeless, digressive, bad taste. And, we could add, it is not even a beautiful dream.”
