Presents simple and inexpensive demonstrations of properties of metallic glasses. (SL)

Presents an experimental method for introducing special relativity which utilizes the distinction between Doppler effects for sound and for light. (SL)

In a senior modern physics laboratory, design" or ingenuity" experiments were introduced to acquaint students with methods of doing complete experiments. The former deals with proposed long term studies while the latter deals with apparatus and short term actual studies. Students rated the design" experiments higher. (Author/TS)

Discusses the philosophy and operation of a self-instructional laboratory at MIT which utilizes visual materials reinforced by audio tapes and is designed to give the student a taste of how to collect, display, and interpret data. Indicates that the approach results in the flexibility needed to serve self-paced courses. (CC)

Discusses the use of a set of experiments to provide undergraduate electrical engineering students with a knowledge of the state of the art in modern coherent optics from an engineering standpoint. (CC)

Presents three notes on new equipment, techniques, or materials of interest to teachers of physics. (HM)

Presents an undergraduate laboratory exercise in elementary statistics in which students verify empirically the various aspects of the Gaussian distribution. Sampling techniques and other commonly used statistical procedures are introduced. (CP)

Discusses a simplified Millikan oil-drop experiment which emphasizes the enplanation of basic concepts in mechanics and electrostatics, the use of home-made apparatus, the request for an individual's observation of his own drop, and the application of statistical analysis in data interpretation. (CC)

Describes the use of Marchant 1016PR with a magnetic tape reader, Monroe 1665 with a punchcard reader, and Hewlett-Packard 9820A with an X-Y plotter to conduct introductory physics laboratory programs. Indicates that the course allows more physics to be done in the same amount of time. (CC)

Discusses a demonstration in which the near and far focusing distances of a student volunteer are measured and his or her glasses prescription is computed. (HM)

Describes an exercise developed by the author to help college students to become familiar with the technique of photoelectric photometry of variable stars and permits each student to work with data he or she has personally obtained. (HM)

Provides an account of the way in which one small university has coped with limited funds and a small staff to provide laboratory activities for freshman physics courses. (CP)
