A Discussion of attempts to understand the great inter-relationships among all areas of knowledge" by Neils Bohr, a physicist, and others. (SE)

The often observed and misunderstood phenomenon of movement of black and white vanes in toy radiometers under illumination is discussed in a generalized non-mathematical manner. Effects of light pressure, low gas density, friction, heat, and motion are illustrated. (JM)

Discusses an experiment for the measurement of the half-life of cosmic ray muons by using a single scintillator detector. (LS)

discusses the cosmology theory of a black hole, a region where an object loses its identity, but mass, charge, and momentum are conserved. Include are three possible formation processes, theorized properties, and three way they might eventually be detected. (DS)

Describes a one semester introductory physics course for physical science students with PSSC and calculus as prerequisites. Course content concentrates on the properties of the electron, positron, andphoton. Summarizes the student evaluation of the course and the laboratory equipment used. (Author/DS)

Describes an experimental use of computer terminals for instructional purposes in a university-level general physics course over a two-year period. Programs have been written to simulate physical problems otherwise difficult for the student to investigate. (Author/DS)

Describes a novel instructional method for physics involving the use of a computer assisted instruction system equipped with cathode-ray-tube terminals, light pen, and keyboard input. Discusses exercises with regard to content, mediation, scoring and control. Several examples of exercises are given along with results from student evaluation. (LC)

College students in physical science, physics, and engineering physics, who responded to a questionnaire were not well informed regarding U.S. space activities. (BR)
