Pauli makes some remarks on the non-homogeneous Lorentz group and also on the unsatisfactory approach to the space-time continuum in physics.
Sem títuloPauli makes further remarks on entropy and measurment. He also replies to a mathematical question asked by Fierz.
Sem títuloPauli writes about the magnetic moment of $H_{3}$. He is working on the theory of it with Villars.
Sem títuloPauli writes about his plans for his visit to Sweden.
Sem títuloPauli asks Heisenberg for a contribution to a special issue of "Dialectica" about complementarity.
Sem títuloPauli replies to some points in Heisenberg's letters (18th April 1947 and 20th June 1947). The idea of an analytical continuation of the S-matrix is a failure. He is scepticalabout future theories, especially as the problem of the dimensionless constant e2/(n.c) is not solved. He doesn't believe in the existence of a universal length. He does not believe either in the mathematical existence of a convergent quantum electrodynamics with arbitrary e2/(n.c). He writes of his impending visit to Sweden and Copenhagen.
Sem títuloPauli received an invitation to India from Dr. S S Nehru and he is asking Bhabha for more details. He thinks his visit would be possible in 1949. He says that Dr. Villars has made a theory on the magnetic moments of H3 and Jost has extended the theory of the emission of many low frequency photons.
Sem títuloPauli says that he thanked Nehru for his invitation, but declined because he plans a visit to Sweden and Copenhagen in September. He told Nehru that he has accepted Bhabha's invitation.
Sem títuloPauli gives titles of his two lectures in Lund.
Sem títuloPauli makes remarks on Jordan's five-dimentional theory and on Pauli's tensor calculus.
