Describes the development and provides an example of the type of student investigation that is now considered sufficient for the practical part of the 'A' level physics examination. (GS)

The superpowers are making decisions about tactical and nuclear weapons which may be immutable for Europe for the next 20 years. The maintenance of arsenals for tactical and nuclear weapons should be discussed by more than just the closed circle of professional strategists-by journalists, politicians, philosophers and thoughtful citizens. (BT)

Describes a method in which metals can be identified by the direction of the e.m.f. generated when the junctions in a circuit containing two dissimiliar metals are at different temperatures. (MLH)

Describes a simple experiment using an inexpensive RCA 931A photomultiplier, in which a measurement of the secondary electron emission coefficient is measured at the last dynode. (MLH)

Describes a course that covers such topics as the archeological dating processes and methods that enable the identification and authentication of artifacts, including X-ray diffraction, optical emission spectroscopy, infrared spectroscopy, and neutron activation analysis. (MLH)

Described is an advanced undergraduate physics laboratory experiment for determining an area, and bandwidth-independent parameter, D* ("dee star"), of an infrared detection devices' detectivity. (SL)

Discussed is the need for examining the reasons for teaching optics to help to determine how optics should be taught. (SL)

Describes and evaluates a line of modular electronic instruments that are designed for use in physics instruction, including a power supply, function generator, and counter/timer. (MLH)

Analyzes section 8 of Einstein's relativity paper of 1905, "On the Electrodynamics of Moving Bodies," in its historical context. Relates this section to the rest of the relativity paper, to the genesis of relativity theory, and to contemporaneous work on radiation theory. (Author/MLH)

Describes two experimental apparatus which may be used to demonstrate the skin effect phenomenon. One apparatus shows the decrease of a magnetic field as it penetrates a thickness of metal; the other demonstrates the decrease with depth of current in a wire. (Author/MLH)

Discusses an experimental curriculum project in Hungary that introduces quantum mechanics into the secondary school. Briefly covers the following topics: superposition and intensity of waves, de Broglie wavelength, the uncertainty principle, ground states, quantum numbers, and symmetry. (MLH)

Describes 5 solar energy experiments that can be used in secondary school: flat-plate collector, solar thermoelectric generator, simple concentrators, solar cell, and natural storage of solar energy. (MLH)

Describes a set of student projects, each involving about 240 hours of laboratory time, covering the following topics: wind power monitoring, wind generator design, solar power, and the heat pump. (MLH)

Participants in the symposium of the Committee on the Status of Women in Physics at the meeting of the American Physical Society heard reports and summaries on 10 National Science Foundation funded studies that sought to determine factors influencing education and career decisions by women in science.
