Abstract
PROF. J. R. PARTINGTON writes : I knew Planck as professor of theoretical physics in the University of Berlin. His course was spread over more than one year, and I began with the last and most difficult part, comprising thermodynamics, the theory of heat, relativity, and quantum theory, next year taking the first part, which dealt with general mechanics and the theory of deformable bodies. The lectures began at 9 a.m. in the University building in Unter den Linden; they were very well attended, and there were always many standing around the room. As the lecture-room was well heated and rather close, some of the listeners would from time to time drop to the floor, but this did not disturb the lecture. The windows were all closed, partly because of the intense cold and partly because of‘the noise of the changing of the guard outside. There was also an exercise class, conducted by Planck himself, which nominally began at 8 a.m., but usually about 8.15. The medical lectures began at 6 a.m., so the University building was well aired by that time.
