Heisenberg writes about Weisskopf's calculations regarding self-energy.
Heisenberg, WernerHeisenberg replies to Pauli's critical remarks about his last letter.
Heisenberg, WernerHeisenberg writes on the quantization of the outer electron of an atom on weak external magnetic fields and in increasing fields until the Paschen-Back-effect.
Heisenberg, WernerHeisenberg writes about the Einstein - de Haas effect, the failure of Bohr's theory of He, his own work with Born and about Lande's theory of multiplets.
Heisenberg, WernerHeisenberg writes on stability considerations in H$_{2}$ and about failure of the energy-calculations for He.
Heisenberg, WernerHeisenberg writes on the recent Göttingen theory of the anomalous Zeeman effect.
Heisenberg, WernerHeisenberg writes about Einstein's objections to Bohr's radiation theory and Born's comments on Kramer's dispersion formula.
Heisenberg, WernerHeisenberg writes about the intensity rules of Ornstein as correspondence of the correspondence principle.
Heisenberg, WernerHeisenberg writes about Pauli's latest work and congratulates Pauli for all the "lies" contained in it.
Heisenberg, WernerHeisenberg corrects a mistake he made in an earlier letter to Pauli, where he wrote "Einkristall" but meant 'Kristallgitter". He claims that calculation of energy levels in the new quantum mechanics is completely fixed once the multiplication rule for Fourier series is accepted. He is convinced that the new quantum mechanics is correct.
