Sugiura sends a reprint on angular distribution of the X-ray spectrum with comments.
Sugiura, YoshikatsuSommerfeld expresses his satisfaction about Pauli's paper on closed electronic shells and about his principle of 4 quantum numbers.
Sommerfeld, ArnoldSommerfeld talks about his article in the Planck issue of Annalen Phys. and about his interest in non-integer quantum numbers. He is optimistic about the future of physics and thinks that someone will soon understand the elementary particles, the Pauli-principle and the divergencies. He is less optimistic about the future of civilization.
Sommerfeld, ArnoldSommerfeld makes remarks on the unipolar induction
Sommerfeld, ArnoldSommerfeld suggests that Pauli writes a review on his "optics".
Sommerfeld, ArnoldSommerfeld expresses his admiration over Pauli's "Handbuch-article on Quanta". He says that Schrödinger's wave mechanics does not yet solve the riddle of quanta.
Sommerfeld, ArnoldSommerfeld discusses a work on unipolar induction. He criticizes Weibel's criticism of Sauter's diffraction theory.
Sommerfeld, ArnoldSnyder talks about his failure so far to obtain significant results as regards his theory in the light of Pauli's critical comments.
Snyder, Hartland S
