Robert Karplus founded the Science Curriculum Improvement Study, an experimental program designed to improve elementary school science education. Its headquarters are at the University of California in Berkeley, where Dr. Karplus is a professor of physics. The program encourages pupils to interpret their own observations under guidance.
Theodore H. Berlin was a professor at the Rockefeller Institute until his death in November 1962. At the March 1964 meeting in Philadelphia of the American Physical Society, two sessions of invited papers were given in Dr. Berlin's memory. The speakers included S. A. Goudsmit, Leon Madansky, Kasimir Fajans, E. W. Montroll, C. N. Yang, Joseph Ford, and Mark Kac, whose address is printed below. Although Dr. Berlin contributed to many fields of theoretical physics, his main interest was statistical mechanics.
Two decades of electron physics are discussed in the following article, based on a paper delivered at the April 1964 APS meeting. The author is chief of International Relations at the National Bureau of Standards.
