Heisenberg thanks Pauli for the invitation to the symposium in Zurich.
Heisenberg, WernerHeisenberg must cancel his participation in the philosophical congress in Zurich because of his journey to the U.S.A.
Heisenberg, WernerHeisenberg comments on Pauli's calculations on the Lee model. He writes about his own work, especially on Bosons of zero mass in his model.
Heisenberg, WernerHeisenberg writes on the application of Pauli's ideas to quantum electrodynamics and on the avoidance of ghosts.
Heisenberg, WernerHeisenberg talks about some relations between Lee's theory and his.
Heisenberg, WernerHeisenberg writes on the difficulties of the renormalization procedure.
Heisenberg, WernerHeisenberg writes a summary of his theory: axiomatics, properties of elementary particles, ghosts.
Heisenberg, WernerHeisenberg writes on an invariance property of the ghost solutions.
Heisenberg, WernerHeisenberg talks about the arguments of the Japanese physicist Kita. He is against Pauli's rejection in principle of infinite metrics in the Hilbert-space. He writes on his own optimism as regards the present state of field physics.
Heisenberg, WernerHeisenberg believes that the whole electrodynamics can be derived from his model, giving a definite value for e$^{2}/h.c.
