Notes that the rigorous kinetic theory, based on the Boltzmann equation, does not yield exact results although some texts claim this to be so. Stresses that they should be presented as approximations with an indication that refinements in the values are possible. (MVL)

Reviews a list of recommendations developed by the Council on Research & Technology (CORTECH). Suggests summer internships for math and science teachers, more funding for higher education, increasing the number of minorities in science, providing corporate continuing education, and increasing communication between industry, government, and…

Discussed are selected application and future trends in supercritical fluid chromatography (SFC). The greatest application for SFC involves those analytes that are difficult to separate using GC or LC methods. Optimum conditions for SFC are examined. Provided are several example chromatograms. (MVL)

Described is a physics course for satisfying the junior-year writing requirement. Gives nine assignment examples of the course. Discusses the use of the writing component as a teaching aid in junior level "Electricity and Magnetism" course. (YP)

Discussed is a method of measuring the coefficient of linear expansion of a solid. Getting many data points, using a computer program using the least square fit technique, and modifying the apparatus are described. (YP)

A rationale for a science of context is provided. Suggests environmental science as such a science. Two teaching programs are used as examples of successful programs. (CW)

Discusses the use of an overhead projector for the deflection of a vertical image to a screen. Describes three demonstrations: magnetizing of a steel ball bearing and paper clip; convection currents of a hot liquid within a cold liquid; and oscillation of concentrated salt solution into fresh water. (YP)

Attempts to show that in the closed loops of cyclic structures the protons situated in conic regions above and below the ring will be shielded. Uses the diamagnetic and air stable octahedral tin(IV) complexes of porphyrins for study. Notes complexes crystallize easily and offer spectacular purple colors. (MVL)

Summarizes the way in which the nation is preparing scientists and engineers to meet the needs of industry and society. States that by offering special science and mathematics enrichment programs and providing good enthusiastic teaching, young people can be recruited to the sciences. (RT)

Presents an energy function E(p) containing a single integral and one variational parameter, alpha. Represents all two-electron integrals within the local density approximation as a single integral. Identifies this as a simple treatment for use in an introductory quantum mechanics course. (MVL)

Presented are the results of a survey of several classes in a college of agriculture to determine whether students had different attitudes about being taught by professors vs. teaching assistants. Data indicated that professionalism and course content are the most important variables to students. (CW)

Described is a technique for taking a large monolith for the purpose of teaching soil structure. Materials and procedures are detailed. A survey of 93 students indicated that the larger monolith was preferred over the commonly used narrow ones. (CW)

Described are three physics experiments: (1) "Holographic Prism"; (2) "Teaching about Energy with the Gravicar"; and (3) "The Coherer." In each experiment, a brief description of the experiment devised is provided with diagrams and references. (YP)

Describes making a cardboard frog. Discusses the physics of various motions of the frog. Provides diagrams showing how to make the frog, the motions, and the mechanics formulas. (YP)

Discussed is the twentieth anniversary of Cornell's program on science, technology, and society (STS); one of the country's largest and most influential. Described is the current status of STS programs around the country. Surveys social problems affecting STS areas. (MVL)
