The new Civil/Mineral Engineering Building on the University of Minnesota Minneapolis campus is a demonstration design in energy conservation and innovation in active and passive solar energy applications. Its antecedents at the university represent contributory steps in the identification of issues and the development of design principles. (MLW)

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…

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 Solar City Daegu 2050 Project (SCD 2050) represents a comprehensive model for shaping the future of this city of 2.5 million residents with a mixed industrial and services economic base. Its specific aims are as follows: realization of a carbon footprint consistent with standards of global sustainability and equity; the development of a…

Qualitative analysis schemes are used in undergraduate laboratory settings as a way to introduce equilibrium concepts and logical thinking. The main component of all qualitative analysis schemes is a flame test, as the color of light emitted from certain elements is distinctive and a flame photometer or spectrophotometer in each laboratory is…

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…
