This article discusses the need for more accurate and complete input data and field verification of the various models of air pollutant dispension. Consideration should be given to changing the form of air quality standards based on enhanced dispersion modeling techniques. (Author/RE)

Microprocessor-based student experiments are described, including flowcharts of a typical program for time interval measurement and experimental and measurement subroutines. (JN)

Describes ray tracing techniques and the method of virtual mirrors to locate images when using multiple mirrors. (JN)

Suggesting that physics need not be entirely mathematically oriented, offers examples and personal anecdotes illustrating how the applications of physics in other disciplines can be used to supplement traditional lectures and the physics of everyday phenomena. (JN)

Describes the design of a simple yet flexible microprocessor and how to construct it using a breadboard. (DC)

Following a list of six recommendations of the 1970 International Conference on Education for Physics Teaching, summarizes content and conclusions of major sessions of the 1980 Conference. Sessions focused on teaching interactions, concepts and misconceptions; evaluation and assessment, constraints and realities of physics instruction, and…

Presents transcripts of freshmen engineering majors solving elementary physics problems to examine some limitations of formula-centered approaches to problem solving. Although students use formulas successfully, the qualitative conception of the underlying physical situation is weak. Results from written tests indicate that this phenomenon may be…

A physicist argues for the establishment of ground rules in the current nuclear power debate so that vital policy decisions and discussions stay within the realm of rationality permitting useful and meaningful exchanges of information and data. (BT)

Provides physics teachers with comments on the value and role of demonstrations during lecture sessions. (SK)

Describes the structure and content of a four-year physics/microcomputer degree program at the University of Surrey. (SK)

Focusing on history of physics, which began about 600 B.C. with the Ionian Greeks and reaching full development within three centuries, suggests that the creation of the concept of the atom is understandable within the context of Greek physical theory; so is the rejection of the atomic theory by the Greek physicists. (Author/SK)

Discusses the meaning of symmetry of the laws of physics and symmetry of the universe and the connection between symmetries and asymmetries of the laws of physics and those of the universe. An explanation of Hamilton's principle is offered. The material is suitable for informal discussions with students. (Author/SK)

Electronic energy levels in noble gas atoms may be determined with a simple teaching apparatus incorporating a resonance potentials tube in which the electron beam intensity is held constant. The resulting spectra are little inferior to those obtained by more elaborate electron-impact methods and complement optical emission spectra. (Author/SK)

Presents ten selected physics notes which could be used in school physics courses. Each includes the name of the author and a description of activities suggested. A reading list is also presented. (HM)

Discusses the deficiencies of presenting the theme of energy in the current West German school textbooks. The article emphasizes the structural importance of entropy for the understanding of energy and suggests how the physics teacher can contribute to the development of an appropriate attitude toward the energy crisis.
