Describes the basic procedures for use of an electron-spin resonance spectrometer and potassium azide (KN3) in an experiment which extends from the phase of sample preparation (crystal growth, sample mounting, and orientation) through data taking to the stages of calculation and theoretical explanation. (Author/DS)

Described is the use of the Doppler Effect with microwaves in the measurement of the acceleration due to gravity of falling objects. The experiments described add to the repertoire of quantitative student microwave experiments. (Author/DS)

A magnetic multipole apparatus suitable for the physics teaching laboratory is described. The apparatus enables the student to measure the magnetic field configuration of a single large coil, and of systems of one or more small coils. (Author/DS)

A technique is presented for producing holograms using equipment which is already in the possesion of the majority of college physics departments, which includes a slightly modified Michelson interferometer, a helium-neon laser, and a long focal-length lens. Production of high quality holograms has been achieved by inexperienced undergraduates…

Described is a laboratory experiment in measurement of electrostatic potentials to help students gain an idea of potentials, which will provide a basis for deeper understanding of electricity and magnetism. The theoretical potential in this report is derived by taking into account the boundary of the actual experimental setup. (Author/DS)

Described is the use of cleavage as an aid to microscopic determination of unknown minerals by immersion methods. Cleavages are examined in relation to fragment shapes, types of extinction, and cleavage-optical relationships. (Author/DS)

Describes the nineteenth century wave machines which can be found in the Smithsonian Institution, at Kenyon, and other colleges. Included is information about the apparatus, queries, and descriptions of different wave machines and how they work. Information included may inspire the reader with similar apparatus to repair it and use it again.…

A regression equation incorporating grade point average (GPA), calculus grade, and grades in two sections of the Pharmacy College Admission Test was significantly more useful than using GPA alone. A minimum sum of scores in three PCAT sections was most effective. Cross-validation with new samples was recommended. (Author/CP)

This article describes an introductory physics laboratory program which teaches three skills: (1) the ability to make estimates and order-of-magnitude calculations, and to use these to check experimental work, (2) the ability to use qualitative and quantitative statistics, and (3) the ability to describe an experiment in one's own words.…

Examines current usage of the term "biomechanics" and emphasizes the importance of differentiating between structure and material. Describes current prolects in biomechanics and lists four points about the educational significance of the field. (GS)

Presents information about the structure, protection of the structure, fuel, atmospheric effects, zone layer impact, and safety relative to the operation of the Concorde that might be of interest to a chemist. (GS)

Presents results of a study regarding the status of the teaching of ethics in American higher education. Five general goals are proposed in the report for the teaching of ethics and recommendations are made for the introduction of new courses in ethics. (CS)

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

Discusses the conflict between the religious and scientific imaginations as existing between the intellectual realms of unquestioning faith and constant questioning. Relates this conflict to writers of the seventeenth and eighteenth centuries, e.g., Bacon, Kepler, Wilkins, Godwin, Harrington, Campanella, Cyrano, Le Bret, Defoe, Swift, Voltiare,…

Summarizes results of a questionnaire asking if the ASC standarized test influences what is taught in inorganic chemistry courses. Chief controlling factors are indicated to be: (1) instructor's preference and (2) textbook content. Suggestions are given to enhance amount of inorganic chemistry in undergraduate curricula.
