An incident occurred in the physics laboratory at the University of Göttingen. An expensive measuring device, for no apparent reason, suddenly stopped working, although Pauli was in fact absent. James Franck, the director of the institute, reported the incident to his colleague Pauli in Zürich with the humorous remark that at least this time Pauli was innocent. However, it turned out that Pauli had been on a railway journey to Zürich and had switched trains in the Göttingen rail station at about the time of the failure. The incident is reported in George Gamow 's book Thirty Years That Shook Physics, where it is also claimed the more talented the theoretical physicist, the stronger the effect.
