This course introduces graduate students and advanced undergraduates to coal science and technology. Topics include: (1) the nature and occurrence of coal, (2) its chemical and physical characteristics, (3) methods of cleaning and preparing coal, and (4) processes for converting coal into clean solid, liquid, and gaseous fuels, as well as coke.…

Traces physics curriculum innovation in Southeast Asia since the 1950s. The unique features of such innovation in Indonesia, Malaysia, Philippines, Singapore, and Thailand are highlighted. Forecasts for the future of physics education in part of the world are also discussed. (Author/HM)

Reviews several previously published uses of disposable plastic syringes and presents ten new uses in several different areas of physical science. (Author/GA)

Describes an experiment based on Faraday's one-piece generator, where the rotating disk is replaced by a cylindrical permanent magnet. Explains the apparent paradox that an observer in an inertial frame could measure his absolute velocity. (GA)

Describes an introductory physics course for liberal arts majors presented in a manner consistent with Piagetian developmental psychology. The course is organized and offered through lecture demonstrations and homework problems with emphasis on the historical processes of concept formation and the humanistic side of physics. (GA)

A model of Brownian motion is discussed which includes viscosity effects. The model lends itself to Monte Carlo simulation and thus is suitable for an elementary physics laboratory experiment. (BB)

Explores in a non-mathematical treatment some of the hydrodynamical phenomena and forces that affect the operation of ships, especially at high speeds. Discusses the major components of ship resistance such as the different types of drags and ways to reduce them and how to apply those principles for the hovercraft. (GA)

Investigates the development of the concept of heat by children aged four to nine. Analysis revealed 11 thought patterns classified into six categories underlying children's concept of heat. These categories are related to scientific knowledge of the physics of heat. (HM)

Three demonstrations are described: paramagnetic properties of Fe(11) and Fe(111), the preparation of polyurethane foam: a lecture demonstration and the electrolysis of water-fuel cell reactions. A small discussion of the concepts demonstrated is included in each demonstration's description. (MR)

Describes science-related competitive events in which 10th and 11th grade students participated. The organization and operation of the olympiad is detailed. (CP)

Argues for the inclusion of additional science history in the Nuffield physics curriculum. (SL)
