Describes the objectives and content of a physics laboratory program for freshman students at the British Columbia Institute of Technology. The first part of the program consists of basic physics experiments, while the second part emphasizes student work on projects in geophysics that have direct technical applications. (LC)

An optical dectector consisting of a high-speed PIN diode and a transistor was evaluated for use in student experiments with a pulsed-ruby laser. Pulses with 36-nsec risetimes were clearly resolved. (LC)

A 1-hour laboratory exercise which demonstrates the correctness of the relativistic relationship between energy and momentum is described. In addition, a value of Planck's constant and the velocity of light can be derived. (JN)

Physicists at the European Organization for Nuclear Research discovered W particles using a giant particle accelerator. Existence of the particles confirms a 15-year-old theory about the nature of the universe, proving that electromagnetic and weak forces are related and raising hopes for a comprehensive theory which includes the strong force. (JN)

Described are recent developments and discoveries in radioastronomy. Topics discussed include galactic structures, stellar evolution, the binary pulsar and general relativity, extragalactic radioastronomy, model of the source of radioactive emission and quasars. (DS)

Described are several techniques and pieces of equipment developed by the Police Scientific Department Branch in its application of physics to police problems. Topics discussed include fingerprints, documents, and photographs. (Author/DS)

Summarizes results of a survey conducted by the Manpower Statistics Division of the American Institute of Physics (AIP). Questions were asked of nine member societies of the AIP concerning demographic and employment data such as professional self-identification, type of employer by highest degree, primary work activity, and annual salary.
