This publication is part of the "Space in the Seventies" series and reviews the National Aeronautics and Space Administration's (NASA) earth orbital scientific research programs in progress and those to be pursued in the coming decade. Research in space physics is described in Part One in these areas: interplanetary monitoring platforms, small…

Presents a theory about the origin of the elements and the evolution of the stars. Relates the nucleosynthesis of nuclides to stellar evolution. (GS)

Traces the history of various theories about Mars that were derived through direct observation. (MLH)

The author, a physicist, chemist, and geologist, describes the new frontiers of scientific research. (Editor/RK)

Asserting that the skills required to tell time by the Big Dipper necessitate both considerable classroom preparation and outdoor practice, this article is designed to help teachers and students prepare for both. Written for students at the fourth grade level, this article includes simple instructions and illustrations. (JC)

A short history of Newton's work in optics, mathematics, and astronomy. (BB)

Describes a method of acquainting physics and astronomy students with the general theory of relativity. (SL)

Provided is a schematic diagram of the projector and a circuit diagram of the optical and electrical components of a simple planetarium that will seat 12 people. There is also a simple map showing major concepts of introductory positional astronomy. (AJ)

Last article in a series reviews online databases in fields of astronomy, earth sciences (geology, oceanography, other geosciences), and materials science (interdisciplinary subject encompassing ceramics, polymers, metals, glasses, etc.), noting coverage and search strategies. A table of 28 databases citing major subjects, producers, and starting…

Presents a condensed version of textbook account of cosmological theory and principles. Topics discussed include quasars, general and special relativity, relativistic cosmology, and the curvature of spacetime. Some philosophical assumptions necessary to the theory are also discussed. (JM)

Describes science activities which have been successful with nonscience majors. Each activity requires students to make observations, record the data gathered, interpret data, and prepare a written report. Subject areas include motion of stars, sunspots, lunar orbits, sunset points, meteor showers, and sun shadows. (JN)

About one-third of the physics majors in the class of 2001 took more than 4 years to complete their undergraduate studies. The most common reasons were receiving a double major and changing majors. There are 761 departments in the US that confer at least a bachelor's degree in physics. These programs produced 4091 bachelor's degrees in the class…

This symposium will provide insights into collaborations among scientists and science educators in a variety of contexts-large research universities, small state and private institutions, and collaborations involving both pre- service and in-service programs. The session will begin with a brief framing of these collaborations as management of the…

Discusses new problems arising from the growing observational data through radio telescope arrays, involving the origin of radio sources, apparent superluminal velocities, conversion of radio sources to relativistic particles, and the nature of compact opaque and extended transparent sources. New physics may be needed to answer these cosmological…
