Background information, procedures, and results obtained are provided for two experiments. One measures the field strength at a particular moment to an accuracy with a level of error less than two percent. The other gives continuous readings or potentials in the field. (JN)

Describes how to modify the commercially available and inexpensive Griffin-Worden (Kontes) glass pressure reactors to permit sampling of homogeneous reactions, without changing the relative concentration of species present. All required parts necessary for the modification are commercially available. (JN)

Quantifies the interaction of a tennis ball and a tennis court surface. Also shows how, by making a few simple measurements, one court surface can be compared to another court surface. (JN)

Provides the rationale for and examples of experiments designed to test the stability of protons and bound neutrons. Also considers the unification question, cosmological implications, current and future detectors, and current status of knowledge on proton decay. (JN)

Describes an experiment designed to introduce physics majors to the triggered oscilloscope. The experiment uses an inexpensive, easily constructed generator which sends pulses down a long coaxial cable, thus providing useful waveforms. (DH)

Suggests several techniques for using large parabolic detectors (radio and television dishes) to reinforce principles of physics. Includes discussions of: (1) electromagnetic rays, (2) angles of incidence/reflection, and (3) mathematical derivation of focus location. (DH)

Discusses a report of a project that aimed to research needs and develop materials for the teaching of physics in vocational high schools. Describes the model that provided the framework and terminology for discussion at all stages of development, evaluation, and revision of materials. (JOW)

Discusses the role and importance of physics in the engineering curriculum, considering the need for physics knowledge in technology transfer and in preventing architectural disasters. Also discusses preuniversity physics preparation in Saudi Arabia and an optimum engineering physics curriculum, outlining a proposed four-semester physics course.…

What is encompassed by mechanics is discussed in terms of its use to show the ability of mathematics to model the real world. How and when to include mechanics in teaching mathematics is then illustrated and discussed. (MNS)

Presents a syllabus indicating the essential physics content suggested for all students aged 11-16. Major topic areas include matter, energy, interactions, electronics, and physical quantities. Includes commentary on treatment for low ability students and on additional content related to General Certificate of Education (GCE) and Certificate of…

Describes an instructional approach in which students submit topics of interest. The study of these topics begins with a student report followed by questions and discussion with the instructor developing the major concepts. (GS)

Presents a semiclassical description of the interaction between a free atom and a weak optical field under conditions of either a stimulated emission or a stimulated absorption resonance. (MLH)

Discusses the application of the tunneling interpretation to the study of guided light waves. (MLH)

Traces the history of the so-called optical theorem in scattering theory from its beginning over 100 years ago to recent applications of its generalizations. (MLH)

Discusses the use of a co-teaching approach in a calculus-based, first-year, elementary physics class. Presents student questionnaire responses along with a discussion of the techniques, advantages, and disadvantages of this method of teaching. (MLH)
