Presents a cylindrical cardboard model that helps students at the graduate or undergraduate level to visualize the nature of simultaneity and the propagation of light in a rotating coordinate system. (HM)

Represents the results of a survey study which was conducted in 1975 to collect hard data concerning the physics lecture and laboratory requirements at 32 colleges and universities with accredited engineering programs. (HM)

Relates biographical information about Einstein's life and work at Princeton. Mentions his work in relativity theory, quantum physics, and his friendship with Niels Bohr. (MA)

Presents a discussion of the early developments in the field of quantum chemistry. (BB)

Describes recent changes in the A-level physics syllabus of the University of London. Discusses the new emphasis on understanding and applying rather than pure role learning, and the changes in testing procedures caused by this emphasis. (MLH)

Presents a method for determining the approximate radius vector of a planet or asteroid from two closely separated observation positions, using mathematics suitable for lower division college students. (MLH)

Presents a procedure for finding the elements of the orbit of an astronomical object from three or more observations. From a set of assumed elements an ephemeris is calculated and compared to the observations. (MLH)

Discusses general guidelines for systematically allocating limited resources by separating educational goals, determining priorities, and assigning to each those resources that serve it best. (MLH)

Discusses how students can investigate the relationship between the current and the voltage across a field coil by using a current that has a triangular waveform. (MLH)

Analyzes an NSF-funded program in which the State University of New York provided training and curriculum assistance to school systems in the Long Island region seeking to improve their elementary school science programs. Reveals that, although initial program objectives were achieved, pilot projects did not lead to school-wide adoption. (MLH)

Describes methods for maintaining enrollments and student credit hour production in physics and discusses the implications for staffing general education courses in physics departments. (MLH)

Discusses the problem of the order, reducibility, and equivalence of systems of Dirac gamma matrices. Gives a simple systematic method for finding the matrices connecting different systems of 4 x 4 gamma matrices. (MLH)

Demonstrates a method for solving linear differential equations with polynomial coefficients based on the fact that the operators z and D + d/dz are known to be Hermitian conjugates with respect to the Bargman and Louck-Galbraith scalar products. (MLH)

Explores major expectations of Mach's principle concerning motions due to matter in the rest of the universe. (MLH)

Discusses the problems encountered in translating the term "solid-state" into French. Its various English uses are outlined, and a list of French equivalents are provided. (Text is in French.) (CLK)
