Pauli makes some critical remarks on a letter by Fierz about the entropy change during a measurement. He adds a short reference to Bohr's view on this problem.
Sem títuloBohr was glad to receive Pauli's article which gives an excellent account of Einstein's pioneering work in quantum theory. Bohr does not know what to answer to Pauli's questions concerning some changes Bohr should make in his paper. The detailed account of the discussions which he had first planned turns out to be much too long for the occasion. Therefore, he is trying to confine himself to the general epistemological aspects of the attitude taken in the discussions, and he has started on a much shorter article which he hopes to have ready very soon. In a few days Bohr will write to Pauli again and tell him how things stand so that it can be decided how to make the best out of it all.
Sem títuloPauli talks about the edition of the Einstein volume. He is glad about Bohr's positive attitude as regards the issue of "Dialectica" on complementary. He also writes on entropy and observation.
Sem títuloAbout a special issue of the journal 'Dialectica' dealing with the concept of complementarity. W. Pauli requests a contribution from N. Bohr.
Sem títuloPauli does not accept Caldirola's suggestion to connect experiments of Lattes, Occhialin and Powell with equations developped by Corben and Schwinger and gives two reasons for it.
Sem títuloPauli thanks Hulthén for sending the French edition of Lagervist's work on the Lamb shift.
Sem títuloPauli agrees with Casimir that quantum electrodynamics have entered a new phase and refers to the recently discovered fact that the magnetic moment of an electron at rest is somewhat larger than Bohr's magneton.
Sem títuloPauli refers to some points for a future discussion with Fierz: 1) on the problem of divergencies in quantum electrodynamics 2) on the relation between concepts and sense perception. He also writes on the laws of nature as physical manifestation of archetypes and he refers to Kepler and his polemic with Fludd.
Sem títuloPauli asks Jordan to send his cosmological works to Prof. Lichnerowicz at Strasbourg. He writes about Jung's interest in parapsychology. He has a negative opinion about a book by an American psychologist, E White, on the "Unobstructed Universe".
Sem títuloEinstein sends his contribution on the subject of complementarity for the periodical Dialectica. Einstein writes about the new progress he made in the extension of the gravitation equation. Alas he was not yet able to obtain a strong and free of any singularities field equation for interesting physical cases. Einstein looks forward to seeing Pauli and his wife in an expected visit. He ends his letter on some remarks on American politics.
