This rare distinction shows that both of these reviews have become classics of the 20th century theoretical physics literature. It is perhaps surprising that in his later years, Pauli the great critic himself had come to admit th General principles of quantum mechanics at he really was a classicist and not the revolutionary innovator he had thought himself to be in his youth.The success story of these two review artiGeneral principles of quantum mechanics

But all the qualities of Pauli’s writing - his logical insight, his precise formulation, his cautious judgement and his care with details - could not prevent these two articles to be obsolete when they appeared in print. The more important of them, the “Quantenthcorie” of 1926, is a review o General principles of quantum mechanics f the old Bohr-Sommerfeld theory, updated only by occasional footnotes to include electron spin and the exclusion principle.

His first contribution to the old theory was his doctoral thesis on the hydrogen molecule ion written in Sommerfeld’s institute and submitted to Munich U General principles of quantum mechanics niversity in 1921. More important was his investigation of the anomalous Zeeman effect since it culminated in the paper on the exclusion principle (JaGeneral principles of quantum mechanics

Dirac’s theory not only generalised the Pauli spin matrices but also led the way out of the dilemma of the Schrodingcr-Klein-Gordon equation of 1926, which as a one-body spin-zero theory could not exclude negative probabilities. The description of this dilemma and General principles of quantum mechanics its resolution by Dirac’s multi-component wave function is one of the showpieces of Pauli’s exposition in the “Wellenmechanik” of 1933.

For this reason, Pauli modified and considerably shortened both the introduction to the relativistic one-body problem and the section on negative energy states in the edition of 1958.There are two other, quite innocent-looking, changes in this part General principles of quantum mechanics of the 1958 edition. The first is a modification of the footnote concerning the tensor quantities formed with products of the y-matrices. While in theGeneral principles of quantum mechanics
old version Pauli expressed his dissatisfaction with the particular representation used to derive the quadratic identities of this footnote, the new Wolfgang PauliGeneral Principles of Quantum Mechanicsringer-Verlag Berlin Heidelberg New YorkWolfgang PauliGeneral Principles of Quantum MechanicsTran General principles of quantum mechanics ndamental theorem, namely that the 4 X 4 matrix representation is irreducible, has been mentioned already in the 1933 edition.The second innocently looking change concerns Weyl’s two-component equation for massless spin-} particles which Pauli had rejected in the 1933 edition because of its parity v General principles of quantum mechanics iolation.

This was in 1928 when he joined the Swiss Federal Institute of Technology (ETH) in Zurich. It was therefore natural that the 1933 edition contained a section on quantum electrodynamics. Onqyear later, Pauli had shown (in a paper with Weisskopf) that in a second-quantised form the spin-zero K General principles of quantum mechanics lein-Gordon equation was as satisfactory as the spin-} Dirac theory.
