The field of inquiry into how atoms are bonded together to form molecules and solids crosses the borderlines between physics and chemistry encompassing methods characteristic of both sciences. At one extreme, the inquiry is pursued with care and rigor into the simplest cases; at the other extreme, suggestions derived from the more careful inquiry…

This booklet provides a reference to the quantities, units, and their symbols which are used in physical science. It is a revision of a 1969 report and takes account of the progress which has been made in obtaining international agreement on the definitions, names, and symbols for units and on the rules for the expression of relations involving…

The study indicates that jobs in astronomy have become severely limited in the last few years, with a near balance between supply and demand of astronomers. The following issues are assessed in this study: the current supply of astronomers in the United States, and its change as a function of time; the background and make-up of astronomers in the…

Described are problems and techniques for safe disposal of radioactive waste. Degrees of radioactivity, temporary storage, and long-term permanent storage are discussed. Included are diagrams of estimated waste volumes to the year 2000 and of an artist's conception of a permanent underground disposal facility. (SL)

This document provides a listing of 500 abbreviations and acronyms related to physics with the definition of each. Each abbreviation was used in journals received by the Purdue University Physics Library during the years 1973-1976. (SL)

Argues for increased use of films in physics education and lists some of the most outstanding physics films. (CP)

Discusses some aspects of the logical consistency of quantum physics and its relation to the usual definitions of reality. (MLH)

Discusses how to make and fly boomerangs. (BB)

Some applications of mathematics to bicycle gearing, speedometers, and bicycle braking are discussed. A method of calculating bicycle speed is developed. (MP)

Discussed is the problem of finding the volume common to two intersecting right circular cylinders. (MP)

Describes an experiment illustrating a lesson in wave interference using bright colors in a soap film. Illustrations provided. (MA)

This article establishes a systematic way for the student to enumerate the various possible arrangements for particles distributed among energy levels. (Author/BB)

Describes some of the techniques that enable the amateur microscopist to make scientifically revealing photographs, using simple and inexpensive equipment. (GA)

Reports on some recommendations made by a subpanel on High Energy Physics Manpower for the purpose of employing additional physicists through the transfer of some postdoctoral monies to produce long-term positions, and the creation of a five-year national fellowship program. (GA)

Discussed are how models arise, are used, and abandoned in favor of some different theory. Maxwell's work in electromagnetic theory is used as an example. (MDR)
