Describes a computer program which plots electric field line plots. Includes program listing, sample diagrams produced on a BBC model B microcomputer (which could be produced on other microcomputers by modifying the program), and a discussion of the properties of field lines. (JN)

Presents two short microcomputer programs which illustrate features of nonlinear dynamics, including steady states, periodic oscillations, period doubling, and chaos. Logistic maps are explained, inclusion in undergraduate chemistry and physics courses to teach nonlinear equations is discussed, and applications in social and biological sciences…

Presents a system that permits students to engage directly in the process of modelling and to learn some important lessons about models and classes of models. The system described currently runs on RML 380Z and 480Z, Apple II and IIe, and BBC model B microcomputers. (JN)

The use of a microcomputer as the basis of a multichannel analyzer (MCA) system is described. Principles of microcomputer MCA, choice of microcomputer, input-output port, data display, MCA program, and interrupt routine (with flowchart) are the topic areas considered. (JN)

The Rockwell AIM 65 is recommended for use in physics laboratories. Among advantages cited are that the basic board can be purchased customized; for example, it can be purchased with or without a printer, power supply, extra memory, and other items. In addition, the computer is basically designed to control equipment and take data from peripheral…

A BASIC computer program was written for an experiment that measures the time of a fall of a ball-bearing dropped through a measured distance. However, the timing subroutine was written in machine language. The reason for using machine language, the machine language program, hardware used, and the experiment are discussed. (JN)

Describes a microcomputer-based, multichannel digital data acquisition system for acoustic signals. Hardware and software considerations are included. (JN)

Describes an undergraduate laboratory experiment in which a moving coil galvanometer is studied and the electromotive force generated by the swinging coil provides the impulse response information in a form suitable for digitizing and inputing to a microcomputer. Background information and analysis of typical data are included. (JN)

Describes: (1) two experiments using a laser (resonant cavity for light and pinhole camera effect with a hologram); (2) optical differaction patterns displayed by microcomputer; and (3) automating the Hall effect (with comments on apparatus needed and computer program used); and (4) an elegant experiment in mechanical equilibrium. (JN)

Describes how color graphics are built up on microcomputer displays and how a range of colors can be produced. Discusses the logic of color formation, noting that adding/subtracting color can be conveniently demonstrated. Color generating techniques in physics (resistor color coding and continuous spectrum production) are given with program…

Describes a data acquisition system developed for an undergraduate engineering students' instructional laboratory at Georgia Tech. Special emphasis is placed on the design of an A/D Converter Board used to measure the viscosity and temperature of motor oil. The Simons' BASIC Program Listing for the Commodore 64 microcomputer is appended. (LRW)

Discusses the realities of implementing a computer-assisted program in high school level science classes, offering some practical suggestions for making such a program successful. Also includes information on several software packages for interfacing microcomputers to sensing equipment. (JN)

Describes the methods and materials used to obtain satellite pictures from weather satellites. Discusses possible physics lessons which can be done using this equipment including orbital mechanics, and how the satellite works. (CW)

Describes software, hardware, and devices that were designed to provide students with an environment to experiment with basic ideas of mechanics, including nonlinear dynamics. Examines the behavior of a Lorenzian water wheel by comparing experimental data with theoretical results obtained from computer-based sensors. (MDH)

Reviews two computer software packages for use in physical science, physics, and chemistry classes. Includes "Physics of Model Rocketry" for Apple II, and "Black Box" for Apple II and IBM compatible computers. "Black Box" is designed to help students understand the concept of indirect evidence. (CW)
