Letter from W. Pauli to E. Kahler.

Letter from W. Pauli to E. Panofsky.

Pauli writes about the publicity given to Heisenberg in radio and press. He writes about the prospects and difficulties of his joint work with Heisenberg. He writes about his participation to the solid-state seminar in Kittel.

Pauli replies to Wentzel's letter which gives hope that Schafroth, Bardeen, Bogoljubow and Wentzel will find a model of supra-conductivity. He writes about the Max Planck medal.

Pauli sends his timetable for the next two months. He writes about two ways of dealing with the Uhlenbeck-Pais models, and about Glaser's approach.
