Described is a rock encyclopedia combining rock sample sets and encyclopedic word and picture entries which can be used as a realistic information resource for independent study or as a part of a course. (JT)

Reports proceedings of the First Annual Workshop at the Interface of High School and College Chemistry, sponsored by the Cincinnati Section of the American Chemical Society. The conference brought together secondary and college chemistry teachers in an effort to establish communication and enhance interaction between the two groups. (Author/CS)

Thermochemical cycles are used to decide which hypothetical compounds might exist and, if not, what is the factor that condemns them to non-existence. Hypothetical compounds of rare gases provide examples of the approach with added historical interest that thermochemical considerations led to prediction and demonstration that XePtF-6 was stable.…

Provides syllabus for courses in introductory polymer chemistry (including major topics and recommended time allotments) and currently available textbooks and audio courses which may be used with the syllabus. Syllabus topics are congruent with those used in American Chemical Society (ACS) standardized examination in polymer chemistry. (Author/JN)

Describes interactive, computer-graphics program emulating behavior of high resolution, ultraviolet-visible analog recording spectrophotometer. Graphics terminal behaves as recording absorption spectrophotometer. Objective of the emulation is study of optimization of the instrument to yield accurate absorption spectra, including…

Describes a semi-automatic viscometer which incorporates a microprocessor system and uses optoelectronics to detect flow of liquid through the capillary, flow time being displayed on a timer with accuracy of 0.01 second. The system could be made fully automatic with an additional microprocessor circuit and inclusion of a pump. (Author/JN)

Describes modification of a gas viscometer to produce a low cost instrument with high precision and safe design. Three tungsten electrodes are mounted in the viscometer using graded glass seals and a ball trap is inserted between mercury reservoir and all external stopcocks. Also describes modifications in experimental procedures. (Author/JN)

Describes an experiment in which parameters from an "ab-initio" potential are used to calculate vibrational-rotational energy levels and construct a "stick spectrum" for the overtone emission of the hydroxyl radical. Provides background information on ab-initio spectrum, experimental procedures, and analysis of data. (Author/JN)

Highlights a symposium on analytical applications of nuclear magnetic resonance spectroscopy (NMR), discussing pulse Fourier transformation technique, two-dimensional NMR, solid state NMR, and multinuclear NMR. Includes description of ORACLE, an NMR data processing system at Syracuse University using real-time color graphics, and algorithms for…

Based on the premise that most engineering students will own their own microcomputers, discusses the teaching of circuit analysis, possible directions to be taken in hardware analysis, and impact on the mathematics related to circuit analysis. (SK)

Specific illustrations are given of questions and problems designed to lead students in introductory physics courses into visualizing and reasoning qualitatively about physical phenomena. Examples include phenomena related to mechanics, electrostatic/magnetic interactions, resistive direct-current circuits, and Thompson's experiments marking the…

Develops simple numerical estimates to quantify a variety of energy economics issues, including among others, a modified Verhulst equation (considers effect of finite resources on petroleum) for supply/demand economics and a phenomenological model for market penetration also presents an analysis of economic returns of an energy conservation…

Distinguishes between computer hardware and software and discusses status of software, application development productivity, software production, and research directions. (JN)

Describes UNIX time-sharing operating system, including the program environment, software development tools, flexibility and ease of change, portability and other advantages, and five applications and three nonapplications of the system. (JN)

Supplies information to answer typical student questions relating to the significance of "plus" and "minus" superscripts used for electronic states of linear molecules. (SK)
