Explains using exponential mathematics, the effect of growth on rate of consuming energy resources. Concludes that we are running out of energy resources at a greater rate than many people think. Lists few options left such as conservation by stopping growth of consumption, recycling, and research to develop alternate sources. (GA)

Presents a picture of the conditions in which discoveries are made and the effort required to reconstruct the conditions in which past discoveries were made. (SL)

Compares the features and the philosophy underlying the "bookstrap" model of strongly interacting particles with the concepts of Mahayana Buddhism. Indicates that a study of Eastern ideas might lead to the new viewpoint necessary for the future development of the hadron physics. (CC)

An analog solution was obtained for the Nenst-Planck and Poisson equations which describe the ion concentration across a simple membrane held at a potential difference. The electric field variation within the membrane was also determined. (Author/TS)

Describes an interdisciplinary course for advanced undergraduates in the physical and biological sciences. The goal is to understand a living cell from the most basic standpoint possible. The ideas of physics, chemistry, and molecular biology are all essential to the course, which leads to a unified view of the sciences. (PR)

Describes using computer-based interviews as a research technique for investigating how students think about physics. One program called Graphs and Tracks, designed for use as an instructional aid, displays motions of a ball rolling along a track. Another program called Atwood, requires students to predict effects on motion or graphs of motion.…

Presents innovative ideas that have been incorporated into the applied physics program at the Humacao Campus of the University of Puerto Rico since 1981. Describes a program that was designed as a professional (terminal) one with mechanisms to guide students who wish to pursue graduate studies. (Author/YDS)

Describes a course for graduate teaching assistants aimed at familiarizing them with teaching techniques besides lecturing and to demonstrate how teachers' behaviors affect student learning. Utilizes a threefold format: each teaching associate is videotaped while teaching, each analyzes his videotape, and weekly seminars are held. (Author/GS)

Provides a list of 25 books in the areas of science history, physics-and-society issues, physics and politics, and the social responsibility of physics. The authors feel that the materials cited would be most useful for potential teachers of physics-and-society courses. (CP)

Samples of filtered airborne particulate, collected daily for the first month after the September 18, 1977 Chinese nuclear detonation, showed fourteen fission products. Fluctuations in the daily fallout activity levels suggested a global fallout orbit time of approximately twenty days. (Author/BB)

A simple Monte Carlo method is used to simulate an atomistic model of solid-state diffusion. This approach illustrates some of the principles of diffusion and in particular verifies a solution to Fick's second law. The role and calculation of the diffusion correlation factor is also discussed. (Author/BB)
