Everett, A. Gordon – Geotimes, 1973
Descriptors: Ecology, Environmental Education, Geology, Reports
Peer reviewed Peer reviewed
Diebold, John – Chemical and Engineering News, 1973
A need is mentioned, for the modern world, to keep constant check of the trajectory of events that it actually seems to be on, instead of relying on instant and fashionable prophecy. (Author/DF)
Descriptors: Ecology, Environmental Education, Environmental Influences, Resource Materials
Wallace, W. – South Australian Science Teachers Journal, 1972
Descriptors: Laboratory Techniques, Photographic Equipment, Photography, Resource Materials
Peer reviewed Peer reviewed
Smith, Waldo E. – Bulletin of the Atomic Scientists, 1973
The author argues that forecasts of quick depletion of resources in the environment as a result of overpopulation and increased usage may not be free from error. Ignorance still exists in understanding the recovery mechanisms of nature. Long-range forecasts are likely to be wrong in such situations. (PS)

Giacconi, Riccardo – Physics Teacher, 1973
This new field, generated from observations above the atmosphere, has been an unexpected gift to astronomy by giving a better understanding of the role and importance of high energy phenomena. The history, instrumentation, and types of celestial sources observed are discussed. (DF)

Page, Thornton – Science Teacher, 1973
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)

Peer reviewed Peer reviewed
Veverka, J. – Science Teacher, 1973
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)

Gursky, Herbert – Science Teacher, 1973
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)

Berglund, Rene A. – Science Teacher, 1973
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)

Levin, Richard R. – Science Teacher, 1973
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)
