Reports on the present and future of the ERIC Clearinghouse on Reading and Communication Skills. (MM)

Impressions of the second International Congress on Mathematical Education are recounted by the author, by M. L. Cornelius (commenting on problem solving, teacher education, and geometry) and by P. Holmes (citing international mathematics education and mathematical applications). A paper by W. W. Sawyer on mathematics clubs and student magazines…

This article is directed to provoking thought on how to attain economic and social objectives while using fewer energy sources. (DF)

The pre-conference documentation, the discussions and the reporting on the United Nations Conference on the Human Environment all indicate the need for information if efforts to solve serious environmental problems are to be successful. Librarians and information specialists must aim for the development of an effective environmental information…

Report on the conference held in Oslo, Norway, in December of 1972. (Editor)

Recent manned and unmanned space probes have detected hydrogen geocorona and airglow emission bands on the night side of the earth, formed by interplanetary materials. (DF)

The Mariner 9 mission has shown that surface changes, thought previously to be a by-product of some form of life, are intimately connected to strong Martian winds which scour the surface. Close-up photographs of the two moons dispel the notion that they are artificial satellites. (DF)

Objects and energy sources are detected whose existence was only hinted at a few years ago. The X-Ray sky has a large number of sources along the Milky Way, most of which lie within 30 degrees of the galactic center, plus a number of faint sources associated with external galaxies. (DF)

The space shuttle, which will be developed for space transportation in the 1980's, will make space flight simple, less time consuming, and less expensive. (DF)

An experimental space station having three-man crews which will live and work there for periods up to 56 days is designed to provide data needed for long-duration space flight and future spacecraft design. This project will answer many scientific and medical questions. (DF)

This section of the annual report on the chemical industry presents data on these areas of chemical production: growth rates, man-made fibers; the 50 largest volume chemicals, major inorganics and organics, plastics, drugs, magnesium, and paint. Includes production figures for 1961, 1969, 1970, 1971 and percent change for 1970-71 and for 1961-71.…
