Bering, Charles L. – Journal of Chemical Education, 1985
Examines energy interconversions in photosynthesis, limiting the discussion to areas pertinent to chemistry (particularly the energetics of the light reactions). Topic areas considered include bioenergetics, photochemistry, conversion of light energy into electrical potential energy, the chemiosmotic hypothesis, and others. (JN)

Cortel, Adolf – Physics Teacher, 2000
Describes a quantitative approach to the demonstration that the energy of a photon is proportional to its frequency. (CCM)

Jacobs, Stephen F. – American Journal of Physics, 1979
Presents two derivations of the fundamental laser linewidth that have been used successfully in introductory physics courses. The cause of the finite linewidth is identified with phase fluctuations in the electric field due to spontaneous emissions. A factor of 2 discrepancy between the energy and field analysis is explained. (Author/GA)

McKinley, John M. – American Journal of Physics, 1979
Using a photon-counting technique, finds the angular distribution of emitted and detected power and the total radiated power of an arbitrary moving source, and uses the technique to verify the predicted effect of the earth's motion through the cosmic blackbody radiation. (Author/GA)

Angelos, Rebecca; And Others – Journal of Chemical Education, 1979
Spectroscopic aspects of the triboluminescence spectra of three Lifesaver candies are discussed. Emphasis is placed on the experimental methods of measuring spectra and origins of the tribaluminescence. (SA)

Fodor, Jerry A. – Scientific American, 1981
Describes several different philosophies of mind with each philosophy's explanation of the mind-body problem. Philosophies discussed include dualism, materialism, functionalism, radical behaviorism, logical behaviorism and central-state identity. (DS)

Trefil, James S. – 1983
This 12-chapter book examines different phenomena as viewed by those trained in physics. These views (or vistas) are promulgated to demonstrate that the infinite variety of things seen in the material world can be reduced to a handful of general laws and to share with the public the richness of the scientist's world view. The phenomena examined…

Poole, R. T. – Physics Education, 1983
Examines the physical basis for colors of noble metals (copper, silver, gold) developed from energy conservation/quantum mechanical view of free electron photoabsorption. Describes production of absorption edges produced by change in density of occupied valence electron states in the d-band, which allows stronger absorption in the visible photon…

MacIsaac, Dan; Kanner, Gary; Anderson, Graydon – Physics Teacher, 1999
Explains the scientific concepts, technical designs, and materials that make up incandescent light sources. (WRM)

Jordan, Thomas M.; And Others – Science Teacher, 1992
Presents a model of a generic atom that is used to represent the movement of electrons from lower to higher levels and vice-versa due to excitation and de-excitation of the atom. As the process of de-excitation takes place, photons represented by colored ping-pong balls are emitted, indicating the emission of light. (MDH)

Hofstadter, Douglas R. – Scientific American, 1981
Discusses Heisenberg's uncertainty principle in simple terms. Presents scientific examples leading to the development of the principle and describes popular misconceptions associated with it. (SK)

Weichman, F. L.; Austen, D. J. – American Journal of Physics, 1979
Describes the details of constructing, and use of, a solar collector. Uses a black liquid to absorb the energy, the thermosyphon effect to drive the liquid through the collector, and a floodlamp as a surrogate sun. (GA)

Crane, H. Richard – 1992
This book is a collection of 66 "How Things Work" columns from the journal "The Physics Teacher," 1983-1991. All the devices and phenomena are ones that are met in everyday life, involve physics principles, and require explanations that are not immediately obvious. Topics include: touch panels in elevators, liquid crystal…

Roseman, Leonard D. – 1978
These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. This module is concerned with the exchange of energy between an organism and its environment in…
