Outlines the contributions of J. H. Jeans to the laws of radiation and explains the interactions of Jeans with Rayleigh and Lorentz. (GS)

Some quantitative methods are illustrated that might be used to select design elements that are appropriate year-round and matched to the annual climate profile, and, in addition, to apportion architectural and mechanical strategies so that they complement one another. (Author/MLF)

Discusses safety in school laboratories and school lab accidents in Britain and suggests ways of reducing potential hazards of school science. (HM)

An architect designed his combination living and working structure with a central solar heated area and nine thermal zones to make the most efficient use of energy collected. (Author/MLF)

Discusses Barkla's part in the controversy around the J-phenomenon, and the different factors that contributed to the refutation of the phenomenon. (GA)

Information is presented on the use of solar energy for heating and cooling. (BB)

Describes 21 completed projects now using solar energy for heating, cooling, or electricity. Included are elementary schools in Atlanta and San Diego, a technical school in Detroit, and Trinity University in San Antonio, Texas. (MLF)

Applications of this model to problems associated with basic phenomena in radioactivity, heat transfer, neutron chain reactions, RC circuits and vacuum pumping are presented. Example computations for each situation are included. (CW)

Presented is an activity in which a mystery setting is used to motivate students to construct their own decay curves of melting ice used as an analogy to radioactive decay. Procedures, materials, apparatus, discussion topics, presentation, and thermodynamics are discussed. (CW)

The Centers for Disease Control and Prevention (CDC) now categorizes skin cancer as epidemic. Nearly 90% of these deadly cancers start from sun exposure during the childhood years. This makes sun exposure in school-age children a serious public health risk, also one that school nurses can address. Solar radiation is now classified as a "known…

This paper reports on a study conducted among Greek kindergarten teachers aiming to explore their conceptual frameworks on a major environmental issue of our times: the ozone layer depletion. The choice of this particular issue was premised on its novelty, complexity and abstractness which present teachers with difficulties in its teaching. A free…

Unified Technical Concepts (UTC) is a modular system for teaching applied physics in two-year postsecondary technician programs. This UTC laboratory textbook, the second of two volumes, consists of 45 learning modules dealing with basic concepts of physics. Addressed in the individual chapters of the guide are the following topics: force…

Communication through the modulation of electromagnetic radiation has become a foundational technique in modern technology. In this paper we discuss a modern day method of eavesdropping based upon the modulation of laser light reflected from a window pane. A simple and affordable classroom demonstration of a "laser microphone" is…

The processes and associated dilemmas of nuclear power plant decommissioning are reviewed in this publication. Decommissioning involves the clearing up and disposal of a retired nuclear plant and its equipment of such a way as to safeguard the public from the dangers of radioactivity. Related problem areas are identified and include: (1) closure…

This conference was held to alert physicians worldwide of the mortal peril of nuclear war to public health, with the hope that they will help educate their communities about the effects of nuclear war. Summary papers prepared during the conference include: medical consequences of nuclear war with special reference to Europe--immediate problems for…
