Explains that the role of physics in a developing country should be relevant and productive. Discusses the state of research in physics, and concludes that it should be geared toward practical and local needs, and that adequate funding is vital. (GA)

Describes a flexible course structure in physics that allows the transfer of students between different programs, up to the end of second year of study. (GA)

Describes a simple method for measuring the heat of vaporization of water, which gives results within five percent of the accepted value. (GA)

Describes a demonstration of P and S (longitudinal and transverse waves), using students' bodies as media, to explain seismic waves in a geology course. (GA)

Describes a laboratory game called SUPERCHARGE, used as an aid to help students understand the concept of equipotential surfaces generated by distributions of charges. (GA)

Describes the following: an electric circuit for an expensive photometer, an amplifier circuit capable of demonstrating many aspects of behavior of free and driven oscillators, and finally a projection recording system which uses an unmodified XY or XT recorder and a separate overhead projector. (GA)

Compares the content of some undergraduate and graduate courses in chemical kinetics and chemical reactor engineering. (BB)

This course is based on the premise that a sound base in the mechanics and electrokinetics of the dispersed phase is essential for an understanding of the macroscopically apparent behavior of such disperse systems. (Author/BB)

Describes an instructional unit on heating and lighting in the home. Discusses the location, production, distribution and use of fossil fuels as well as the production and distribution of electricity. (GA)

Describes the use of atomic spectra that are excited in inductively coupled plasmas for the simultaneous or sequential determination of the elements at all concentration levels. (HM)

Describes the procedure, the circuitry, and the calibration required to convert a voltmeter into a pH meter for use in the physics laboratory. (GA)

A computer program which simulates an interstellar gas and dust cloud has been used to study Kirchhoff's laws of spectral analysis in introductory astronomy courses. The model parameters can be varied to stimulate various effects observed in actual clouds. Students are given exercises to use the program in a manner similar to a lab experiment.…

Calculates the energy-band structure of noninteracting electrons in a one-dimensional crystal using exact and approximate methods for a rectangular-well atomic potential. A comparison of the two solutions as a function of potential-well depth and ratio of lattice spacing to well width is presented. (Author/GA)

Describes a liberal arts physics course for all majors interested in holography or to satisfy the general education requirements. An outline of the course and some experience of offering it are given. (Author/GA)

The work output of a human body in various tasks and the biochemistry of oxygen consumption in muscles is discussed. (CP)
