Pauli gives his opinion on the present situation of quantum electrodynamics.
Sin títuloPauli writes on the concept of individuality in quantum physics and in psychology, on the identity of perception and intuition in the unconscious, and its connection with the concept of time.
Sin títuloPauli has just heard that the second proofs of Bohr's "Dialectica" article have been sent to Bohr. They have to be final and he asks him to return them promptly to the editor. In reading the proofs Pauli noticed a slight error in the German translation of the summary and asks Bohr to correct this. Bohr's article is now excellent. The next time he hopes to write to Bohr about physics again.
Sin títuloSommerfeld thanks Pauli for his article in Naturwissenschaften in honour of Sommerfeld's 80th birthday.
Sin títuloThis is the last letter from the year 1948, written by Pauli just before going home for a New Year's dinner. Pauli is glad to report that he received the issue of "Dialectica" containing Bohr's article. Unfortunately he cannot say anything on the question of the reproduction rights. He has written to the editor again and hopes that Bohr will soon hear something. Pauli was very glad of the "hopeful spirit" of Bohr's letter. He is very interested in the publication of Bohr's old manuscripts, especially the paper with Rosenfeld on the charge measurements. He also thanks him for the copy of the "penetration" paper. He has had no time yet to look at it, because he was working on the new subtractive electrodynamics. He received a paper by Schwinger on self energy and polarisation of the vacuum. He is a master in concealing physical difficulties with mathematical elegance.
Sin títuloPauli writes about a long letter he has sent to Schwinger, Wentzel and Bethe on Vacuum polarization and photon self-energy. He would be interested in Pais, Oppenheimer and Dyson's opinion.
Sin títuloPauli makes more remarks about Schwinger's theory.
Sin títuloPauli congratulates Einstein on his 70th birthday. He remembers gratefully Einstein's address in Princeton 1945 after Pauli received the Nobel Prize. He also writes of his forthcoming contribution to the Einstein volume in the Living Philosophers".
Sin títuloPauli accepts Kronig's invitation.
Sin títuloPauli returns to a problem discussed at the Florence conference concerning irreversibility and the H-theorem.
