An attempt to empirically test conflicting hypotheses on whether scientific discoveries are the result of research by many or few scientists. The data, drawn from physics, supports the hypothesis that physicists making important discoveries depend on the research of a relatively small number of scientists. (Author/JB)

The history of the short film and the single concept film loop is presented. Lists fourteen reasons why it may be necessary to make and use a film loop. Film loop projectors are analyzed according to present features and deficiencies with predictions on future improvements. (DS)

Describes the five-year masters degree program in physics at the Moscow State University. The program combines general instruction in physics and mathematics with specialized research experience. Discusses (1) entrance requirements, (2) course philosophy, and (3) course requirements. Selected examples of questions from the entrance and course…

Details are provided of computer-simulated experiments developed by the co-directors of the Learning Research and Development Center (LRDC), University of Pittsburgh. The initial materials were designed to help students learn physics. New materials are being developed along similar lines for elementary mathematics. The views of the creators are…

Provides a detailed, non-mathematical analysis of total internal reflection based on the interaction of light and matter and the principle of superposition. Discusses factors affecting the critical angle and the percent of the incident beam that is refracted and reflected. (JM)
