Discusses the use of a small computer to solve self-consistent field problems of one-dimensional systems of two or more interacting particles in an elementary quantum mechanics course. Indicates that the calculation can serve as a useful introduction to the iterative technique. (CC)

Mechanical movement, pressure, floating bodies, heat phenomena, electrical phenomena, when applied to military problems "for the patriotic edification and military instruction of the children" excite interest and place theory on concrete foundations. Examples of applied physical concepts follow in this article. (Author/JH)

Reviews the basic theory underlying the lift and drag forces of a magnetically levitated vehicle riding over a continuous sheet guideway. Included are descriptions of the future vehicle characteristics and the students' construction of a superconducting magnetically levitated merry-go-round demonstration apparatus in a laboratory experiment. (CC)

Discusses the construction of a diffractometer table and four microwave models which are built of styrofoam balls with implanted metallic reflecting spheres and designed to simulate the structures of carbon (graphite structure), sodium chloride, tin oxide, and palladium oxide. Included are samples of Bragg patterns and computer-analysis results.…

Presents ideas from readers on techniques and equipment that might be useful in teaching secondary school science. Suggests how to construct cheap wall charts, modify a vacuum cleaner into a blower, construct a stereo microscope lamp holder, and outlines simple physics laboratory experiments. (JR)

Discusses the radioactive waste management in Belgium, Canada, France, Germany, India, Italy, Japan, the United Kingdom, the United States, and the USSR. Indicates that scientists and statesmen should look beyond their own lifetimes into future centuries and millennia to conduct long-range plans essential to protection of future generations. (CC)

At Harvard, physics courses are divided into units that the students can master at their own pace and that offer more student-teacher contact and personal attention. (PG)

Discusses three possible methods of thinking about the implications of the definitions of the Avogadro constant and number. Indicates that there is only one way to arrive at a simple and standard conclusion. (CC)

Develops a simplified electrostatic model of the heart with conduction within the torso neglected to relate electrocardiogram patterns to the charge distribution within the myocardium. Suggests its application to explanation of Coulomb's law in general physics. (CC)

Describes an experiment suitable for high school physics classes in which students determine the wavelength of electromagnetic radiation of u.h.f. television transmissions. Elaborate equipment is not required, and details are given for the construction of a dipole. (JR)

Discusses the development of a model for implementing Project Physics without the use of physics teachers. Indicates that students can study Unit 3, independently, with the aid of the supplementary materials produced in this project and achieve as well as the average student in a teacher-taught class. (CC)
