Describes a game in which the symbol omega becomes equivalent to the word ohm, and is then modified or incorporated into a picture to represent a common word or phrase. Recommends the game as a way of humanizing the beginning course. (GA)

Science activities or experiments described are: (1) plant cloning, (2) determining the cost-effectiveness of gas and electric heating, and (3) a physics project competition. (MDR)

Discusses the role of professional societies in encouraging minority participation in their respective vocations. In particular, the actions of professional organizations of physicists are discussed. (CP)

Urges the restructuring of astronomy-astrophysics courses to accommodate nonastronomy majors. Outlines an alternative approach to teach astronomy. (GA)

Proposes an alternative to the classical minimum-deviation method for determining the refractive index of a prism. This new "fixed angle of incidence method" may find applications in research. (Author/GA)

Presents a simplified theoretical analysis of the variation of quantum yield with photon energy in the photoelectric experiment. Describes a way to amplify the experiment and make it more instructive to advanced students through the measurement of quantum yield of a photo cell. (GA)

Describes a dynamical system which is stable at potential maxima. The maxima, called L-4 and L-5, are stable locations of the restricted three-body problem. Energy loss from the system will tend to drive it away from stability. (GA)

Explains how videotape technology has been used in physics instruction, and that the original design which was intended for independent and self-paced instruction has been broadened to include other areas. (GA)

Describes an experiment that allows the student to estimate the diameter of the fovea in his own eye. (GA)

Describes a personalized system of instruction that has been tried in India and its advantages. Shows that students' responses were favorable to this type of instructional approach. (GA)

Describes an experiment which utilizes the technique of double-exposure holographic interferometry to demonstrate electromagnetic wave radiation-pressure effects on an illuminated object. (Author/GA)

Describes an experiment, in solid-state physics, for measuring the Shubnikov-de Haas oscillations in indium antimonide. It also provides an introduction to low-temperature techniques and to cryomagnetic systems. (Author/GA)

Describes the nature and development of an alternative degree program in the area of physics. The program in engineering electronics prepares electronics technicians for employment in industry as senior technicians or junior engineers. (Author/GA)

Reviews the earthquake phenomenon and its possible relation to ionospheric disturbances. Discusses the basic physical principles involved and the methods upon which instrumentation is being developed for possible use in a tsunami disaster warning system. (GA)

Conflicting views have been put forward on the derivation of the distribution of solubilized molecules among micelles. This stems from failure to consider the arrangement of the solubilized molecules in the micelles. In the treatment presented enthalpy effects are ignored as they are not amenable to a simple general theory. (Author/BB)
