In a modular approach, instruments are considered as systems composed of modules, each module performing a particular function. Examines process of relating specifications for instruments to those for particular modules, effect of microcomputers on modular approach, and extension of the approach to such devices as "hyphenated" or tandem…

Describes the soon-to-be-established National Resource for Computation in Chemistry (NRCC), a user-oriented, federally supported computing center for chemists. Discusses probable funding, staffing and organization, data bases, and the priorities of chemical topics to be serviced. (MLH)

Describes a graduate-level course in physical-organic chemistry in which students learn to solve problems using computer programs available through the Quantum Chemistry Program Exchange. Includes condensed syllabus and time line showing where various computational programs are introduced. (Author/JN)

The use of the analog computer to plot the gain frequency of a system under test is presented. Both linear and logarithmic plots are considered. The method is applicable with almost no frequency restrictions when the system under test is simulated on the computer. (SK)

Describes impact of micrographics; microcomputer simulations of scintillation spectrometry and chemical/enzyme kinetics experiments; various computer programs (formulas and equations and equilibrium demonstration and lunar data plotting, among others); multiplexing in instrument readout displays; microcomputer-controlled flash photolysis…

Reviews the nature of computer networks and previews their development by focusing on ways they are useful to scientists and to science, including applications for remote computer access, electronic mail, bulletin boards, teleconferencing, file transfer, resource sharing, and imbedding nontextual communications. (JN)

A physical chemistry computer program with seven subprograms (available from the author) was developed to present student questions, evaluate mathematical expressions (calculator mode), retrieve tables, and refresh output on the terminal. Criteria for easily adding new questions are listed and sample output included. (SK)

Presents the mathematical background for solving eigenvalue problems, with illustrations of the applications in computer programing. The numerical matrix treatment is presented, with a demonstration of the simple HMO theory. (CS)

Provided are several perspectives on technology, addressing changes in learners related to technology, changes in contemporary life related to technology, and changes in subject areas related to technology (indicating that technology has created such new tools for inquiry as computer programming, word processing, online database searches, and…

Describes the attempts of a teacher to use a personal microcomputer to provide tutoring in an undergraduate physics course. (GA)

Discusses (1) instructional uses of VisiCalc; (2) use of a spreadsheet to calculate the activity coefficients of lead in amalgams from measurements of the potentials of cells without liquid junction; and (3) the computerized solution (analogous to a titration) of simultaneous equations for determining equilibrium pH of a raindrop. (JN)

Teaching and research in physiology encompass increasingly complex notions of the system under study. Computer modeling fosters understanding by extending the ability to formulate, test, and evaluate hypotheses about the system, and to describe experimental data. The exploration of the model system's behavior serves teaching and investigation in…

Describes a program which uses a series of algebraic equations calculating mean skin temperature and mean body temperature. The program, which uses the well-established physiological model by Burton, is written in Microsoft BASIC for TRS-80 microcomputers; however, it can be easily modified for other microcomputers. (JN)

Describes (1) interfacing the Commodore VIC-20 using joystick game ports; (2) a chromatographic integrator for the TRS-80; (3) upgrading input/output capabilities of the TRS-80 color microcomputer; (4) IBM PC interfaced to a Perkin-Elmer DSC-1 differential scanning calorimeter; and (5) an undergraduate experiment in which students design a…

Microcomputers can record laboratory measurements which human laboratory partners can never collect. Simple, harder, and general-purpose interfaces are discussed, with suggestions for several experiments involving an exercise bike, acceleration, and pendulums. Additional applications with pH meters, spectrophotometers, and chromatographs are also…
