Briefly reviews the history of nuclear energy, artificial transmutations, the fission process, and nuclear energetics. A comparison of magnitude is made between chemical and nuclear energy. (CS)

Describes an organic chemistry experiment demonstrating the effect of temperature on reactivity as measured by reverse phase high performance liquid chromatography. (CS)

Presents an undergraduate analytical chemistry experiment that promotes an interpretation of the molecular aspects of solute partitioning, enhancing student understanding of separation science and liquid chromatography. (CS)

Described is a way for an amateur to build a mercury-vapor ion laser which was devised by Dean Morelli. Morelli's laser emits bright pulses of green light and dimmer pulses of red-orange light and is the first gaseous-ion laser. (Author/DS)

Provides information regarding underwater vision. Includes a discussion of optically important interfaces, increased eye size of organisms at greater depths, visual peculiarities regarding the habitat of the coastal environment, and various pigment visual systems. (CS)

Describes electroreceptivity in fishes, including information on electric signals in water, electroreceptors, electric organs, electric sense in weak-electric fishes, electrolocation, electrocommunication, and evolutionary considerations. (CS)

Discussed is the automobile in terms of the Otto cycle, engine heat losses, internal engine losses, drive train losses, road power, and driving habits. Each of these topics is described and calculations are shown to aid the physics teacher in the use of the automobile in the physics classroom. (Author/DS)

Discussed are two current physics research areas. Solar cell efficiencies are discussed relating to present and future conversion efficiencies. Topics discussed in Astrophysics include the observation of astronomical bodies at different wavelengths, in terms of electromagnetic spectrum, tools of astronomy, compact stars, pulsars X-ray binaries,…

Centrifugal Force is described and defined in terms of the underlying theory and terminology with the aid of rigorous analysis of this phenomenon. (DS)

Describes the photodiode array and the electrical connections necessary for it. Also shows a few of the optical demonstration possibilities-shadowgraphs for measuring small objects, interference and diffraction effects, angular resolution of an optical system, and a simple spectrometer. (Author/DS)

Describes a university-wide program directed at reducing the improper storage and disposal of toxic chemical wastes from laboratories. Specific information is included on the implementation of a waste pick-up service, safety equipment, materials and methods for packaging, and costs of the program. (CS)

Indicates that women are eased out of science careers by factors other than a supposed lack of spatial ability. Advocates that the masculine bias in science be reduced through the humanization of science and technology and a realignment of societal goals. (GS)

Describes methods for using the high-resolution electron microscope in conjunction with other tools to reveal the identity and environment of atoms. Problems discussed include the ultimate structure of real crystalline solids including defect structure and the mechanisms of chemical reactions. (CS)

Details rules and lists of cards for a card game based on rummy as an aid in the teaching of cardiovascular physiology, appropriate for first- and second-year osteopathic medical students. (CS)

Provides historical examples of intuitive discovery applicable to the teaching of physics for majors. Cites details for the discovery of Coulomb's law, emphasizing the roles of Joseph Priestley and Henry Cavendish. Also discusses the career of Ivar Giaever, a Nobel Prize winner of 1973 in solid state physics. (CS)
