Discusses various topics related to planetary geomorphology, including: research techniques; such geomorphic processes as impact, volcanic, degradational, eolian, and hillslope/mass movement processes; and channels and valleys. Indicates that the subject should be taught as a series of scientific questions rather than scientific results of…

Measurement of the brightness of moonlight by comparison with lamp-light from a low wattage light bulb is an elementary project in astronomy which illustrates scientific principles for the freshman level. Two methods used for the comparison (shadow brightness method and grease spot method) are explained, with suggestions and expected answers. (DH)

Describes (in separate articles) 20 developments in science, technology, and medicine that were made during the twentieth century and had significant impact on society. They include discoveries related to intelligence tests, plastics, aviation, antibiotics, genetics, evolution, birth control, computers, transistors, DNA, lasers, statistics,…

Discusses types of solar eclipses and the frequency of their occurrence. Emphasis is placed on the May 30, 1984 solar eclipse. Ideas for building a pinhole camera to view the eclipse, to determine if the sun is changing size, and to report scientific findings are provided. (BC)

Presents data on the mathematics attitudes of elementary education majors (N=81) and compares them to data obtained from students in a general astronomy course (N=71). Results indicate that the education students, as a whole, were positive in their attitudes toward success in and usefulness of mathematics. (JN)

Presents a chapter from an introductory college-level astronomy textbook in which full-color photographs and numerous diagrams highlight an extensive description of the planet Jupiter. Topics include Jupiter's geology, rotation, magnetic field, atmosphere (including clouds and winds), and the Great Red Spot. (DH)

Six articles review current understanding and research in solar physics. Included are topics on sunspots, the corona, solar flares, solar waves, and solar-energy generation. Also included is a resume of physical data relating to the sun. (SL)

This issue of Exploratorium Magazine focuses on Antarctica. Antarctica has one of the most extreme climates in the world with an untouched environment inviting researchers with great opportunities for study. This issue describes the journey of four Exploratorium staff members to frozen Antarctica. Chapters include: (1) "Life at the Bottom of…

Solving problems in a visuospatial domain, such as astronomy, may require not only knowledge about the phenomena within the domain but an ability to instantiate knowledge spatially to generate solutions, as well. Spatial ability assessments and interviews of undergraduates show that problem-solving ability can be limited regardless of the…

This report provides data on students earning physics and astronomy Bachelors degrees for the academic years ending in 1999 and 2000. A survey was sent to each of the 763 degree-granting departments that confer physics degrees, and responses were received from 2,721 physics major seniors from both classes. Findings show that physics Bachelors…

This paper describes the PICCO (PICtorial-COmputer) project the aim of which has been to study the development of the children's conceptual models and exploration strategies in the PICCO environment. The phenomenon, which was selected for the pictorial computer simulation, PICCO, was the variations of sunlight and the heat of the sun as…

This report is based on an annual survey of physics degree recipients conducted approximately 6 months after the end of the academic year in which they received their degrees. During the 1997-1998 academic year, there were 1,323 physics Ph.D.s conferred at the 183 departments granting physics doctorates in the United States. Departments reported…

Presents the initial analytical results of 1973 survey data obtained from over 52,500 respondents in the physics and astronomy community. Indicates a decrease in unemployment and a continuous salary increase from 1970 to 1973. Included are descriptions of subfield employment, work activities, and situations of minority groups. (CC)

Briefly describes the nature of comets, and in particular, discusses Comet Kohoutek, one of the most spectacular celestial phenomena of this century. (JR)
