Gustafson is sending Gunnar Källén to Pauli. He reports on Fröberg's scattering work and he is creating a post for Bradt.
Sin títuloPauli recommends his assistant Jost to Bethe. He gives a critical comments on a paper by Dyson about regularization.
Sin títuloPauli thanks Kronig and his wife for their hospitality.
Sin títuloFierz gives Pauli his calculation on $\Box$ G-H.
Sin títuloPauli comments on an essay by Erich Neumann in the Eranos-Yearbook of 1948.
Sin títuloPauli returns to a problem discussed at the Florence conference concerning irreversibility and the H-theorem.
Sin títuloPauli refers to questions regarding the equivalence of pseudovector coupling.
Sin títuloPauli confirms that there will be a physics meeting in Basel in September. Schwinger, Rabi, Fermi, Cockcroft, Dyson and others have promised to come. Pauli is going to Princeton in November, but he will be back in May 1950. He gives some comments on his own latest work.
Sin títuloPauli thanks Weyl for his book on the philosophy of mathematics and natural science. He makes two critical remarks: 1) It is not correct to connect Leibniz with the principle of exclusion. 2) There is no asymmetry of the past-future relation in spontaneous radiation processes, but the concept of spontaneity needs a better definition.
Sin títuloIn this letter, Pauli gives further remarks on Weyl's parallel between Leibniz's principle and the exclusion principle. He also writes on Jung's synchronicity and its relation to causal events. It's said that the "elimination of all uncontrolable factors necessarily leads to destruction of the significance of synchronicity".
