Presents notes on three physics experiments on (1) light and lenses, (2) determination of the pVT surface of a freon, and (3) use of an eyepiece with microscopes and telescopes. (RH)

A course in differential equations for mathematics and physics students is designed to encourage students to models of situations in the sciences. (SD)

Five issues concerning nuclear power--economics, danger from accidents, environmental effects, terrorism, and alternatives are debated, with one paragraph statements from opponents and advocates on each of the topics. (CP)

Relates a technique in which teachers can rate their effectiveness by the examination of students' lecture notes. Students are asked to record notes on a carbon of which the teacher is given the copy. Examination of these notes enables the instructor to ascertain communication problems which may be occurring. (CP)

Describes a project which consists of BASIC programs, teacher's guide, and student's notes on six topics for high school biology, chemistry, and physics. Outlines the supply of physics equipment in high schools in three Australian states and presents a procedure for demonstrating small scale temperature inversion in the classroom. (GS)

Data and arguments are presented to support the contention that there may not be sufficient fuel to run the proposed American light water reactor program. Success of the program may also depend on unproven technology of the breeder reactor. A moratorium in the light water reactor program is recommended. (BT)

Describes a demonstration using a heated wire to illustrate the phase change from the body-centered cubic form of iron to the face-centered cubic form. (MLH)

Students enrolled in an audio-tutorial section of an introductory college physics course responded more favorably than did students in the lecture section on a student questionnaire concerned with attitudes toward the course and laboratory. (MLH)

Reports new equipment, techniques, or materials of interest to teachers of physics. (Editor/CP)

Comments on the reports prepared by the Royal Society Joint Committees concerning the need of mathematics in high school chemistry, physics and biology. (CP)

Discusses the physics of fluids flowing through vessels in the context of blood moving in the circulatory system. The method of presentation used is judged suitable for students in an advanced high school science course emphasizing individualized instruction in an interdisciplinary field. (Author/PEB)

Discusses many popular carnival rides in relation to the physics of their operation. Includes calculations showing the g force produced by various attractions. (CP)

Expounds major theories which cosmologists have proposed to determine size and distances of quasars. Relates these to efforts of 17th century astronomers. (CP)

Proposes a method to estimate the number of civilizations which may exist in the universe. Reviews attempts which have been made to contact these bodies. (CP)
