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…

Although many experiments to detect gravity waves are underway, and others are planned, so far none of them has reproduced Joseph Weber's results, first reported in 1967. (Author/DF)

Most knowledge of planetary atmospheres is gained through spectroscopic techniques. Information regarding what we know about several planets, particularly Jupiter, is presented. (DF)

X-ray emitting bodies orbiting stars have been located. Research on black holes has brought out many characteristics of these X-ray emitting bodies. (PS)

Inconsistencies have arisen between earth-bound observations and data collected from space probes. These inconsistencies center on the moon's structure, temperature, magnetization, composition, and origin. (DF)

A discussion of earth-bound and space observations of lunar data concerning the moon's structure, evolution, age, and chemical composition. (DF)

A brief review of the evidence that nuclear reactions are the main source of stellar energy, how nuclear reactions synthesize the elements, and how nuclear reactions determine the course of stellar evolution. (Author/CP)

When tested outdoors, students receiving instruction in observational astronomy in a planetarium performed better than students taught using a normal classroom with a celestial globe. (AL)
