Argues that a United States built and operated Superconducting Supercollider (SSC) could strain the infrastructure of scientific research. Identifies the areas which would be adversely affected by the funding of the SSC. Advocates construction of the collider as an international enterprise. (ML)

Presents: (1) method for tuning sonometers with a VELA and sensing device; (2) computer simulation of two-dimensional gas diffusion; (3) inexpensive procedure for digitizing with better than 0.5mm precision (with program listing); and (4) a simple optical diffraction analogue apparatus for use with the laser. (DH)

Examines scientific discoveries which underlie the atomic bomb and its technological development in the United States during World War II. Changing views, super-weapon development, early American efforts, production/dropping the bombs, and the Oppenheimer case are considered. (DH)

Described is an inexpensive wave tank used to study the amplitude of tsunamis travelling down a channel of decreasing depth. A detailed discussion to theory and computations is included. (SL)

This book presents a story of the history of gravity, the glue of the universe, and is based on two premises: (1) an understanding of mathematics is not required to grasp the concepts and implications of relativity; and (2) relativity has altered forever the perceptions of gravity, space, time, and how the universe works. A narrative text section…

This report describes a study that investigated the relationship between mental imagery and problem solving in physics, specifically in kinematics. A distinction is made between visual imagery and spatial imagery used in solving physics problems. The results of this study indicate that while spatial imagery may promote problem solving success, the…

The information provided in this booklet is meant to give the necessary background information so that the science of black holes can be taught confidently to secondary students. The featured activities can be used to engage and excite students about the topic of black holes in different disciplines and in a number of ways. Activities include: (1)…

Discusses the use of a simple computer exercise to derive a general law for simple pendulum phenomena with square-law damping. Indicates that less mathematical skills are requires in the computer treatment than in the analytical treatment.

Discusses a lab experiment where rubber bands are used to determine a spring constant and to predict the range when the band is stretched and fired. Included are the formulas involved. (CC)

Discusses the fundamentals of two personnel dosimeters: the lithium fluoride thermoluminescent dosimeter and the silver-activated phosphate glass radiophotoluminescent dosimeter, and indicates the usefulness of this presentation for both teachers and students. (CC)
