Pauli letter collection: letter to Niels Bohr

This 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.
