Famous Wolfgang Pauli Quotes

“As I regard physics and psychology as complementary types of examination, I am certain that there is an equally valid way that must lead the psychologist 'from behind' (namely, through investigating the archetypes) into the world of physics. As an example of background physics, I shall discuss a motif that occurs regularly in my dreams - namely, fine structure, in particular doublet structure of spectral lines and the separation of a chemical element into two isotopes.”

“The theoretical determination of the fine structure constant is certainly the most important of the unsolved problems of modern physics. We believe that any regression to the ideas of classical physics (as, for instance, to the use of the classical field concept)cannot bring us nearer to this goal. To reach it, we shall, presumably, have to pay with further revolutionary changes of the fundamental concepts of physics with a still farther digression from the concepts of the classical theories.”

“Es gibt keinen Gott und Dirac ist sein Prophet. (There is no God and Dirac is his Prophet.) {A remark made during the Fifth Solvay International Conference (October 1927), after a discussion of the religious views of various physicists, at which all the participants laughed, including Dirac, as quoted in Teil und das Ganze (1969), by Werner Heisenberg, p. 119; it is an ironic play on the Muslim statement of faith, the Shahada, often translated: 'There is no god but Allah, and Muhammad is his Prophet.'}”

“It seems significant that according to quantum physics the indestructibility of energy on one hand which expresses its timeless existence and the appearance of energy in space and time on the other hand correspond to two contradictory (complementary) aspects of reality. In fact, both are always present, but in individual cases the one or the other may be more pronounced.”

“What really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.”
