Provides some perspectives on the explosive growth in microscience to show some of the interrelations among science, engineering, and technology. (HM)

Presents a ray-tracing procedure based on some ideas of Herzberger and the matrix approach to geometrical optics. This method, which can be implemented on a programmable pocket calculator, applies to any conic surface, including paraboloids, spheres, and planes. (Author/GA)

Determines the excess surface change carrier density, surface potential, and relative capacitance of a metal insulator semiconductor diode as a function of the gate voltage, using the precise questions and the equations derived with the abrupt depletion layer approximation. (Author/GA)

Diagnoses some of the failings of current methods of teaching physics which are intended to teach both students and teachers of physics as a result of Einstein's contributions to physics. (HM)

Examines present-day and future prospects of the applications of modern magnetohydrodynamics in a number of countries. Explains how the electromagnetic pump, which was invented by Einstein and Leo Szilard, led to the development of applied magnetohydrodynamics. (HM)

Discusses some of the basic theories in cosmology, such as Hubble's laws and the big-bang theories, and looks at some of the ideas of astronomers and scientists with respect to their evaluation of the future of the universe. (GA)

A discussion of Edwin Land's experiments with color images from black-and-white photographs. Information is presented for duplication of these experiments by the amateur photographer. (BB)

Describes a research project undertaken by physics undergraduate students to monitor particulate air contamination in Ponce, Puerto Rico, and to determine the meteorological factors which contribute to it. (GA)

Discusses one of the newest methods used to probe the upper atmosphere using naturally generated infrasound from ocean waves. (GA)

Explains a flexible two-part grading scheme which attempts to mix the best of both the descriptive and analytical treatments of an introductory astronomy course, to allow for differences in the academic backgrounds of the students. (GA)

Describes degree structure, subjects involved, and physics courses offered to students of single honors, as well as double honors, degree programs. (GA)

Describes the decline of public esteem for the scientist and interest in physics. Author discusses the difficulties in recruiting physics students and obtaining federal money. (MA)

Describes the following: a low-pressure sodium light source; a design of hot cathodes for plasma and electron physics experiments; a demonstration cart for a physics of sound course; Bernoulli force using coffee cups; a spark recording for the linear air track; and a demonstration of the effect of altering the cavity resonance of a violin. (GA)

Tries to explain the attraction between unlike charged particles using electromagnetic interaction as described by the quantum field theory. (GA)

Explains how to use glass tubing to form a simple microscope; how to construct an over-voltage protection circuit; and how to demonstrate electromagnetic effects with a coil and rubber bands. (GA)
