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)

Provides descriptions of courses in physics in medical colleges in England. For each institution, entry requirements, course structure, and main branches of research are included among information provided. (CP)

Describes a computer-based homework grading system that accepts a constructed response by the student, multiple attempts, generation of new data for each student, records of performance, and provision of some feedback about answers. (Author/CP)

Explains the laboratory techniques and equipment necessary for the demonstrations. (CP)

Discusses fundamental scientific concepts involved in the measurement of molecular quantities utilizing the mole. (SL)

Discusses the physics of the human ear and hearing. (SL)

Describes a physics experiment for demonstrating magnetic lines of force. (SL)

Discusses the physics of the atomic model prepared, in 1904, by J. J. Thomson. (SL)
