This publication is one of a series of information booklets for the general public published by the United States Atomic Energy Commission. This booklet deals with the handling, processing and disposal of radioactive wastes. Among the topics discussed are: The Nature of Radioactive Wastes; Waste Management; and Research and Development. There are…

This programmed instruction booklet is an interim version of instructional materials being developed by Harvard Project Physics. It is the first of two booklets on the topic of waves and covers pulses, how pulses travel, and what happens when two pulses pass through the same region at the same time. For the second booklet in this series, see SE…

This is the second of two programmed instruction booklets on the topic of waves, developed by Harvard Project Physics. It covers the relationships among the frequency, period, wavelength, and speed of a periodic wave. For the first booklet in this series, see SE 015 552. (DT)

This study was designed to assess the use of an individualized laboratory-oriented high school physics program used in one Black Hawk County, Iowa, school. The three problems investigated were: (1) what short-term and long-term learning resulted from the use of the materials, (2) what student characteristics were related to learning outcomes, and…

The historical development of rocketry and nuclear technology includes a specific description of Systems for Nuclear Auxiliary Power (SNAP) programs. Solar cells and fuel cells are considered as alternative power supplies for space use. Construction and operation of space power plants must include considerations of the transfer of heat energy to…

The operation of nuclear rockets with respect both to rocket theory and to various fuels is described. The development of nuclear reactors for use in nuclear rocket systems is provided, with the Kiwi and NERVA programs highlighted. The theory of fuel element and reactor construction and operation is explained with particular reference to rocket…

This 1971 revision deals with radioisotopes and their use in power generators. Early developments and applications for the Systems for Nuclear Auxiliary Power (SNAP) and Radioisotope Thermoelectric Generators (RTGs) are reviewed. Present uses in space and on earth are included. Uses in space are as power sources in various satellites and space…

This booklet in the "World of the Atom" Series replaces the earlier Books on Atomic Energy for Adults and Children. It includes annotated bibliographies for children (grade level indicated) and adults. Over 60 books are classed as elementary and over 70 as advanced. These are alphabetized by title and also indexed by author. A list of…

Photographs illustrate several principles of physics which can be observed in everyday situations. (CP)

Describes the difference between the approach of statistical probability and the deterministic approach to physical theories. Shows that it is near the truth to see physical theory as a hierarchical structure in which successively complex levels alternate between probabilistic and deterministic explanations. (Author/GA)

Distinguishes between the work done by the source and the work received by the system. Shows that a comparison of the magnitudes of quasistatic and nonstatic work can be carried out only through the use of the laws of thermodynamics. (GA)

Discusses a laboratory experiment in isotope production designed to help the students understand some of the concepts in elementary nuclear physics. (GA)

Derives an equation relating the internal pressure of a rubber balloon to its radius. Shows that the theoretical pressure curve is experimentally verifiable, and discusses the problem of equilibrium configuration of two interconnected ballons. (Author/GA)

The density matrix is used to obtain an expression for the mean value of any spin operator in the scattering of particles with arbitrary spin. The example of spin-1/2-spin-1 scattering is developed and physical information obtained by establishing connections with the polarization tensor and Wolfenstein observables. (Author/GA)
