**University of California at Berkeley, Summer Session, 1928**

With G C Evans and H B Phillips; but not otherwise listed (the next year, Weyl was one of four lecturers at UCB, with three at UCLA; all listed in advance)

Weyl, like Hardy, was visiting Princeton University; although he returned to Zurich, it was this visit that later set him up for appointment at the IAS although he still vacillated over that appointment; the Bulletin of the AMS notes, "he will make an extended tour during the month of May, travelling slowly from Princeton westward to California" (35 (1929), p. 280). Many of his talks were on topics related to mathematical physics.

*Representations of groups, applications and representations of groups for quantum mechanics*

[It is sometimes remarked that mathematics on the West Coast of the USA got off to a somewhat slow and undistinguished start, but it is interesting to note that Carathéodory, Hardy, and Weyl all made the pilgrimage to California.]

Also touring in the USA in 1929 were P A M Dirac, from Cambridge, and E A Milne, from Oxford. Veblen was to try to get Dirac to Princeton for a period similar to Hardy's visit, but with substantial remuneration from Princeton, in contrast to the funds Veblen secured from the International Education Board for his exchange with Hardy; but Dirac was unable to come until the academic year 1930-31.

Dirac lectured on quantum mechanics at the University of Wisconsin in April and May, 1929. He and Milne were two of the four lecturers giving courses at a symposium on theoretical physics at the University of Michigan, 24 June-16 August, 1929: Milne spoke on problems in astrophysics and vector and tensor methods in statics and dynamics; Dirac gave an introduction to quantum mechanics.
