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)

Describes a concentrated course of one week duration in elementary computer physics. The purpose of it is to introduce computer physics and to show how to remove the traditional constraints on physics courses, and to gain insight into the solutions of complex problems using the computer. (GA)

Analyzes using path analysis models, student attainment of the objectives of a first year university physics course. Four aspects of physics attainment are identified: (1) theoretical; (2) applied; (3) experimental; and (4) attitudinal objectives. (HM)

Describes a method of measuring small temperature differences that amount to a .01K, using an arrangement of a copper-constantan thermocouple, a microamplifier and a galvanometer, as an indirect way of measuring heat energy. (GA)

Reports the results of a study designed to measure any changes in the Piagetian level of intellectual functioning of students after taking one introductory college physics course for one semester. No developmental progress was found as a result of taking such a course. (Author/GA)

Describes four demonstrations of the Leidenfrost phenomenon; floating of liquid drops on their own vapor above a hot surface, delayed quenching of red-hot brass by water, explosion of vessels containing suspended liquid droplets, and momentary incombustibility of living tissue immersed in boiling oil. (Author/GA)

Describes an apparatus for investigating the behavior of photoelectrons in a uniform magnetic field in either a vacuum or a low-pressure gas. Presents data and discusses some basic features of the photoelectric effect and the diffusion of free electrons in a gas. (GA)

Because study of climatology in most college and university geography departments is descriptive, it gives no fundamental insights into geophysical processes. In order to achieve a quantified understanding of atmospheric processes, geographers must have expertise in mathematics, physics, and instrumentation. For journal availability, see 506 593.…
