Physics and physicists of the past fifty years
Dr. Wigner, Members of the American Physical Society and of other Societies associated with the American Institute of Physics, and Guests: In the case of British organizations such as the Royal Society and the British Association, it is quite customary for the president to deliver an address of a general, nontechnical character. On the other hand, in the case at least of the American Physical Society, a purely technical paper is much more common. It seems to me, however, that at a meeting where several hundred technical papers appear on the program, at least one nontechnical paper may appropriately find a place.
