The need to provide reliable information on the properties of substances and materials has led to the proposed establishment of a numerical data system. The problems this poses, the most urgent of which is that of developing basic methodological principles underlying the data system processes, are discussed. (32 references) (Author/KE)

A biography of the founding editor is presented concerning his career and his interests in physics teaching. (DF)

The findings of this investigation are based upon an analysis of actual use data recorded from all volumes and issues left by library users on study tables and on trucks in the photocopy area. (27 references) (Author/SJ)

Describes a method for direct calculation of energy levels by using elementary techniques. Describes the limitations of the approach but also claims that with a minimum amount of labor a student can get greater understanding of atomic physics problems. (PS)

Describes briefly the works of the physicist including references to the concept of lubrication. Brief explanations of streamlining, turbulent motion of fluid particles, and method of determining the value of J constant are included. (PS)

It maintains that there is a strong need for clearing the confusion around several theories of gravitation. A comprehensive theoretical framework is suggested against which every theory should be tested. The hope is that only one theory of gravitation will emerge from rigorous examination and provide a strong base for future research. (PS)

Answers to questions in a grade 11 physics examination were analyzed to provide information on the cognitive development of Australian science students. Data from questions concerned with volume, mass and weight, levers and proportion, speed and velocity, acceleration and relative speed are compared with Piaget's findings: many of the students do…

A steady, detectable evolution in the direction of higher quality and greater diversity has taken place over the years. Important changes are underway in two areas: (1) the development of courses, curriculum, and instructional strategies; (2) the evaluation of the effectiveness of teaching and materials development activities. Includes…

Describes the use of the analog computer in the solution of the bouncing ball problem. The problem is treated theoretically and the results of the computations may be observed graphically or on an oscilloscope. Also discussed are the distortions of the ball due to impact, and possibilities of expanding the problem to include more complex…

Three problems in radioactive buildup and decay are presented and solved. Matrix algebra is used to solve the second problem. The third problem deals with flux depression and is solved by the use of differential equations. (LC)

Describes a working model of a Foucault pendulum at intermediate latitudes constructed of a steel drill rod with a steel ball attached at one end. The rod makes an angle of 45 degrees with the rotation axis of a horizontal turntable. The vibrating system is the same as that which led Foucault to construct his first gravity pendulum. (LC)

Surveys the types of computer usage in science education, both current and planned. The computer facilities are classified as interactive, semi-interactive or non-interactive. Interactive facilities make possible educational use of the computer administrator or producer of materials. The computer generally, and each mode in particular, is…

European travel can provide an intimate view of the implements and locales of great discoveries in physics for the knowledgeable traveler. The four museums at Cambridge, London, Remscheid-Lennep, and Munich display a full range of discovery apparatus in modern physics as outlined here. (Author/TS)
