Three methods of studying motion are described. A wind tunnel is utilized in demonstrating flutter. Computer graphics with an oscilloscope are used to investigate the natural modes of vibration and to track the simulated motion of missiles. (TS)

Reviews the functions that should be included in an analytical workstation. Also discusses the common data file structures and the techniques of data interchange between software modules and presents a brief overview of commercial products and their interfacing characteristics. These software include word processors, spreadsheets, database…

Discusses the unique user interface of Apple's Macintosh microcomputer which is changing the way researchers interact with their data. Topic areas addressed include: desktop, mouse, and windows; preparing scientific illustrations; MacPaint; and charts and graphics. Limitations are also noted. (DH)

Taking a prototype chemical reaction (molecular hydrogen plus hydrogen atom), constructs an accurate semiempirical, generalized diatomics-in-molecules potential energy surface, calculates motions of these atoms on this surface using REACTS trajectory program, and presents results as moving picture on a microcomputer graphics system. Provides…

Provides short descriptions of computer application in chemistry including displaying organic molecules, solving stoichiometry problems, developing laboratory schedules, programing periodic chart information on pocket calculators, editing chemical manuscripts, instruction in Lewis Structures of simple molecules, a kinetic simulation system, and…

Procedures for displaying computer-generated text and graphics to a large audience are inexpensive when a Fresnel-mirror projector is used. Although small liquid-crystal displays (LCDs) can be easily projected, large LCDs require some modification (which is described). Other devices with LCD displays (oscilloscopes, televisions, and pulse-height…

Summarizes 13 papers presented at the Fourth Biennial Conference on Chemical Education that dealt with computer-assisted tutorial and graphical instruction of chemistry. (MLH)

A PASCAL graphics and instrument interface program for a Z80/S-100 based microcomputer was developed. The computer interfaces to a stopped-flow spectrophotometer replacing a storage oscilloscope and polaroid camera. Applications of this system are discussed, indicating that graphics and analog-to-digital boards have transformed the computer into…

General principles of computer graphics are reviewed, including discussions of display hardware, geometric modeling, algorithms, and applications in science, computer-aided design, flight training, communications, business, art, and entertainment. (JN)

Presents 11 short descriptions on the applications of computers in chemistry classrooms and laboratories, including among others, using microcomputer graphics to teach quantum theory, a versatile and inexpensive instrument/computer interface, and a microcomputer-controlled scintillation spectrometer. (JN)

Discusses use of two EAI semi-expanded TR-20 units to display solutions to differential equations for harmonic oscillators, quantum-mechanical particles, trajectories, radioactive decay series, and hysteresis curves. Suggests practical applications for both undergraduate physics laboratories and classroom demonstrations. (CC)

Scientists are designing computer models of biological systems, and of compounds with complex molecules, that can be used to get answers once obtainable only by sacrificing laboratory animals. Although most programs are still under development, some are in use by industrial/pharmaceutical companies. The programs and experiments they simulate are…

A method is presented for teaching some topics of kinematics. It involves the use of electronic equipment, which allows active student participation, the systematic analysis and solution of problems, and the use of a quick feedback loop for training. (Author/SK)
