This letter encloses a manuscript by Darwin. Bohr looks forward to meeting Pauli in Como.
Bohr, NielsAbout a manuscript in progress by Bohr and Rosenfeld on "measure problems", Pauli's remarks on a manuscript of a conference by Bohr during the Solvay congress, works on atom structure published in the 'Physical Review'.
Bohr, NielsBohr comments on a book by A Pauly (1905) on "Darwinism and Lamarchism". Bohr gives his attitude to the great progress in biology and psychology made in recent time, in the light of the results of atomic physics as regards the description of phenomene.
Bohr, NielsAbout Wolfgang Pauli's death.
Bohr, NielsBorn accepts an invitation to a symposium. He hopes to enter his new house in Pyrmont in ten days. He writes on his ideas about an indeterministic, statistical formulation of classical mechanics and the transition from the individual state to a statistical equilibrium. He writes of his impending honorary doctorate in Oxford.
Born, MaxBorn replies to a letter from Pauli and gives a clarification of his and Pauli's divergent views as regards the statistical theory of irreversible processes.
Born, MaxBorn expresses a great interest in Pauli's paper on Eyl's theory and agrees in particular to his remark that continuum theory cannot be applied to the interior of the electron because of the introduction of quantities which are in principle unobservable. He suggests to Pauli to prove that the surface energy of NaCl cube is smaller than that of any other surface.
Born, MaxBudini has not yet reached a satisfactory result as regards the orthogonality of the eigen-solutions of an equation connected with the regular representation of the homogeneous Lorentz group.
Budini, PaoloBudini thanks Pauli for his letter. He is now convinced that the eigen-functions in question are not orthogonal to each other.
Budini, PaoloCaldirola replies to Pauli's question about time dilatation.
Caldirola, Piero
