A device which provides an inexpensive means for making precise studies of the kinetics of gas molecules is discussed. Two experiments are described: (1) Measurement of the vibrational relaxation time of gas molecules and (2) determination of intermolecular forces in molecules. (Author/DF)

Describes the theoretical principles and experimental arrangement in determining the transmission and reflection coefficients for polarizations which are parallel and perpendicular to the plane of incidence. Indicates an error of the order of five percent in the results obtained. (CC)

Prospective physics researchers do not get enough background and sophistication in physics at the undergraduate level in a college with no research program. Authors describe an enrichment program for such students that takes place during two summers of an MS degree program. (PS)

Photographs of streakies were used to teach the concept of Rutherford scattering. Magnetic pucks with lights were used as streakies. (PS)

Results are reported on a one year introductory course for Chicano, Black, American Indian, and Asian-American minority students. Teaching innovations employed were edited lecture notes and a class council. Evaluation of student performance including a comparison with students in other introductory physics courses and student evaluation are…

Describes the application of basic dynamics of rotations to the case of turning on skis, first without and then with external torques. Various elements are combined in different techniques and suggestions for further extensions and a list of laboratory exercises based on skiing are included. (DF)

Satyendranath Bose was first to prove Planck's Law by using ideal quantum gas. Einstein credited Bose for this first step in the development of quantum statistical mechanics. Bose did not realize the importance of his work, perhaps because of peculiar academic settings in India under British rule. (PS)
