Describes an experiment which utilizes the technique of double-exposure holographic interferometry to demonstrate electromagnetic wave radiation-pressure effects on an illuminated object. (Author/GA)

To update a traditional construction shop program, students at Passaic Valley High School, New Jersey, developed a mock-up model of a solar-heated A-frame vacation house using prefab construction. The article describes the project and illustrates it with photographs of the model and a drawing of the solar collector. (MF)

After a description of the current constraints on energy growth, the author concludes that solar energy is by far the most attractive energy source. The constraints described fall into the following categories: heat limits, pollution, material constraints, financial constraints, and political limits. (BM)

The potential of solar power satellites as a future means of supplying energy is discussed along with the environmental reasons for using these satellites. (MDR)

Discusses the feasibility of solar housing for northern latitudes. (SL)

The future of solar heated homes looks bright. The increase in availability of solar hardware and information along with tax credits point to an increase in both solar water and space heating. Solar systems can add to the value of a house. (BB)

Describes an experiment studying the decay of moth balls to demonstrate diffusion phenomena. (SL)

Discusses the problem of determining the number of radioactive particles entering a detector window from a parallel and coaxial disk source. (SL)

The new North Campus of the Community College of Denver is heated by solar energy. This article describes the system and its costs. (DC)

Provides instructions for making tin can radiation detectors from empty aluminum cans, aluminum foil, clear plastic, copper wire, silica gel, and fine, unwaxed dental floss put together with tape or glue. Also provides suggestions for activities using the detectors. (JN)

Discusses the theory of radiometric force and the historical development of the radiometer. (MLH)

Discusses three theories used to explain the interaction of electromagnetic radiation with matter: the multiphoton theory, the cascade theory, and the effective photon theory. (MLH)

The proposed Niskey Lake Middle School is designed to have solar heating in half of the building, solar water heating for the entire facility, and solar cooling for the administration area. (Author/MLF)

Discusses textbook errors and alternative explanations concerning Planck's derivation of the distribution function for the energy density of black-body radiation. (MLH)

Includes five brief articles on: solar-heating demonstration equipment, mercury or sodium vapor lamp spectroscopy, an apparatus for simulating variable stars, a voltage-to-frequency converter, and an introductory absorption experiment for low-energy beta particles. (MLH)
