The program employed cassette tape recorders for problem solving, requirement of a high level of mastery (75 percent) and no final exams. Essentially all students were able to achieve the specified mastery level and retain that competence over an extended period of time, accompanied by more positive attitudes toward the course. (DF)

Short articles describe the demonstration of Brownian motion in a bubble included in a quartz crystal, an inexpensive technique for investigating conservation of momentum, a method of teaching vector addition, and ideas for inexpensive substitutes for heavy masses and for additional laboratory bench space. (AL)

The emphasis of the humanistic aspects of physics and the need to make physics understandable to the public are viewed as important in reestablishing public and political support for scientific research. (CP)

Describes an inexpensive, easily constructed device for demonstrating that the speed of light is finite, and for measuring its value. The main components are gallium arsenide light emitting diodes, a light pulser, transistors, and an oscilloscope. Detailed instructions of procedure and experimental results are given. (LC)

Brief descriptions of several of the laboratory experiments which have been incorporated into an acoustics course for music majors. Includes vibratory motion and sound generation, nature, speed, and pitch of sound, spectrum analysis and electronic synthesis of musical sound and some conventional sound experiments. (Author/TS)

Describes an intermediate level mechanics course based on the solution of problems by computer. The nature of these problems and their solution by computer is discussed, and the sources of the programs indicated. (Author/TS)

Describes the advantages and disadvantages of living and teaching in Hawaii with emphasis on situations encountered in the physics classroom. (TS)

Three methods of studying motion are described. A wind tunnel is utilized in demonstrating flutter. Computer graphics with an oscilloscope are used to investigate the natural modes of vibration and to track the simulated motion of missiles. (TS)

Nonphysics majors are presented with a direct current experiment beyond Ohms law and series and parallel laws. This involves construction of an analog computer from common rheostats and student-assembled voltmeters. (Author/TS)

Describes an undergraduate optics laboratory experiment to verify the law of intensity in the Fesnel diffraction of a thin wire. A gas laser as light source and a photocell as detector scan the diffraction pattern. The agreement with the theoretical pattern is remarkably good. (Author/TS)
