Provides an introduction to Debye potentials and simplified derivations of the multipole expansions of electrodynamic fields. (SL)

Describes an oscillating electroscope, an apparatus to verify the time interval between successive events in nuclear decay, and electronic circuits that are the analog of consecutive reactions. (SL)

Demonstrates that if a sinusoidal oscillation of the point of support of a pendulum is approximated by a square wave, a matrix method may be used to discuss parametric resonance and the stability of the inverted pendulum. (Author/SL)

Describes an experiment studying the decay of moth balls to demonstrate diffusion phenomena. (SL)

Discusses computer experiments employing Monte Carlo techniques for describing phase transitions and critical phenomena in theoretical physics. (SL)

Discusses various aspects of presenting a weekly half hour TV science show directed for elementary students. (SL)

Describes physics laboratory apparatus including devices to demonstrate projectile motion, glass cutting, and a pendulum clamp. (SL)

Describes demonstrations, some apparently paradoxical, which can be performed with commercially available magnetic stirrers. (SL)

Presents a triple pendulum used to demonstrate normal modes. Also discusses the mathematical similarity of the equations of three coupled quantum mechanical levels. (SL)

Describes a self-paced, mastery-oriented introductory physics course offered at Cornell University which incorporates aspects of audio-tutorial instruction and the Personalized System of Instruction (PSI). (SL)

Reports results of a study comparing Piagetian level of cognitive development and final course grades for 338 college physics students. Cognitive development is measured via a group questionnaire. Results indicated the correlation between final grade and measured cognitive development was low. (SL)

Describes an inexpensive photo transistor timing system, apparatus for measuring muzzle velocity, and an apparatus for exposing modes of coupled oscillators. (SL)

Describes errors occurring in a textbook presentation of electrical resistance across carbon arcs and filaments. (SL)

Describes a modification to the Jensen and Edwards model current balance utilized in elementary physics laboratories which improves operation and ease of maintenance. (SL)

Cites the increasing need for physicists in medicine. Sketches the qualifications needed to pursue a Master of Science degree (MS) in medical physics fields and provides a brief discussion of Ph.D programs in the field. (CP)
