Applications of wheels are shown to be an invaluable tool in teaching the processes and technology of science. (DF)

An experiment in which both Raman-Nath and Bragg diffraction of light by acoustic waves in water are observed in the sound frequency range from 5 to 45 MHz. The apparatus consists of a laser, light detector, rf power source, quartz transducer, and homemade water cell. (Author/DF)

A description is given in which a computer program can be used to illustrate principles of statistical mechanics. The concepts of ensembles, statistical averages, and responses are classified particularly with respect to the role of statistical fluctuations. (DF)

Describes the operation principles, construction, and accessories of a land or survey gyrocompass. Indicates an agreement within O.1 degree in the direct comparison of the gyro-north with the astronomic north. (CC)

The potential of the computer usage in instruction is discussed. A project was initiated to identify areas where the computer might yield significant advances in teaching. (DF)

Presents a preview of the report by the National Academy of Science Physics Survey Committee, which deals principally with the opportunities for physicists during the 1970's. The 14 chapter report, to be available by midsummer of 1972, considers physics in a broad context and perspective both in science and technology and in the whole of the…
