In this text, written for the general reader rather than for the specialist, the accelerating use of man's environment is considered from agricultural, economic, demographic, and land and other resource use, with principal reference to the United States situation, but with reference to the world scale when appropriate. Environmental threats are…

This book contains five major articles in areas of current importance in air pollution control. They are written by authors who are actively participating in the areas on which they report. It is the aim of each article to completely cover theory, experimentation, and practice in the field discussed. The contents are as follows: Emissions,…

Presented is the utilization of solar radiation as an energy resource principally for the production of electricity. Included are discussions of solar thermal conversion, photovoltic conversion, wind energy, and energy from ocean temperature differences. Future solar energy plans, the role of solar energy in plant and fossil fuel production, and…

Divides the components of the energy crisis into those which demand immediate, moderate term, and long term research efforts. Delineates specific topics in each category and solicits physicists' efforts in these areas. (CP)

Studies the practicality of water-filled flat-plate solar collectors. An estimate of solar energy gathering abilities and applications in heating of homes are considered. (CP)

Mendeleev's prediction of existence of the radioactive element, Polonium, and the discovery of iproniazid and its role in antidepressant therapy are presented. (BB)

The article reviews the literature on environmental causes of learning disabilities, and the appropriate remedial measures. (Author/DLS)

Terraset is a hill with a school inside, located in Reston, Virginia. A solar collector, heat reclamation system, and the earth cover save energy. (Author/MLF)

Discusses the process of star formation. Infrared and radio astronomy, particularly microwave astronomy is used to provide information on different stages of stellar formation. The role of dust and gas which swirl through the interstellar regions of a galaxy and the collapse of a cloud in star formation are also presented. (HM)

Describes the design of a low-cost electronic circuit to serve as a differential thermostat, to control the operation of a solar heating system. It uses inexpensive diodes for sensoring temperature, and a mechanical relay for a switch. (GA)

Presents a derivation of the minimum possible bandwidth of a laser oscillator. (SL)

A retail bookstore and offices for the University of Minnesota's admissions and records department are housed in Williamson Hall. Some 95 percent of the floor area lies below grade; however, window arrangement permits a view of the outdoors or sunlight from almost every part of the building. (Author/MLF)

As background material for a paper on the transuranium elements (SE 537 837), this article reviews: (1) several descriptive terms; (2) nuclear reactions; (3) radioactive decay modes; (4) chemical background; and (5) experimental methods used in this field of research and more broadly in nuclear chemistry. (Author/JN)

Blackbody radiation is used as an example to illustrate that oversimplification in teaching quantum ideas can result in later misunderstanding. Although textbooks give Planck's distribution function in terms of wavelength, there are actually 12 different radiation functions. Some of the more interesting ones are given and discussed. (JN)

Identifies contexts and levels of involvement in which health professionals could make a contribution on nuclear issues. Discusses the implications for continuing education on the anxiety about the health effects of nuclear technology and of the need for information in making decisions about it. (SK)
