Exclusion Principle, Lorentz Group and Reflection of Space-Time and Charge

Zusammenfassung

The 70th anniversary of Niels Bohr’s birthday reminds me of a long and still continuing common pilgrimage since the year 1922, in which so many stations are involved. Without pretension of completeness I mention here only some of them in their relation to the particular subject of this paper which, I hope, he will permit me to dedicate to him on the occasion of this celebration.

I am just writing down the reflection-paper for the Bohrvolume. ... Writing down my ideas I feel that ‘His Majesty’ = Julien Schwinger should know every thing what is in this paper. But he will never tell it, so this will be forever ‘unobservable’.

Pauli an Rosenfeld, 28. September 1954

Pauli’s last achievement is the very curious Lüders-Pauli theorem, which states essentially that in virtue of certain purely formal transformation properties of fields all equations must remain invariant under the combined transformations of change of sign of the space coordinates, change of sign of the time, and replacement of all particles by their antiparticles. This theorem has taken on special significance quite recently when the discovery of parity non-conservation in weak interactions has revealed that in nature one does not have invariance with respect to each of these transformations taken separetely.
