Describes the basic acoustical principles of percussion instruments whose vibrating members are multidimensional. (MLH)

Describes the construction and operation of a temperature programmer; it can be built for less than $100 and can be used with any gas chromatograph that uses a variable resistor to control oven temperature. (MLH)

Discusses the concepts involved in constructing a meaningful free energy plot for a chemical reaction and how these concepts are sometimes insufficiently represented in textbooks. (MLH)

Discusses the preparation of compounds representing six oxidation states of manganese; demonstrations involving these compounds are described. (MLH)

Discusses the philosophy and operation of a chemistry course that emphasizes the impact of chemical science on society and the education of scientifically literate citizens. (MLH)

Describes an experiment in which students answer a set of questions about the structure of a simple molecule given the computer output of a Patterson map obtained by X-ray diffraction. (MLH)

Describes a study designed to explore systematically the practical advantages and problems of using videotapes in the undergraduate chemistry laboratory. (MLH)

Presents an analysis of the deterioration of the engineering profession via the production of an oversupply of engineers. (SL)

Surveys of curriculum changes of (n=163) colleges and universities offering 4-year undergraduate programs in geology found that 77% revised their major geology programs in the previous 3 years and 74% reported that the greatest incentive for change was concern about pedagogy. Includes survey. (MKR)

Describes New York University's commitment to general mathematics and science education for undergraduate students, embodied in the College of Arts and Science's core curriculum, the Morse Academic Plan, which includes a three-course sequence, Foundations of Scientific Inquiry, specifically designed for non-majors. (EV)

Discusses how emerging technologies enhance existing methods of learning and create new ways for institutions of higher education to fulfill their core teaching and learning missions, particularly in science, technology, engineering, and mathematics (STEM) fields. Explores technology planning. (EV)

Described is a new university-industry collaboration designed to attack the scientific "pipeline" problem from a materials science perspective. Discussed are the results of a conference that sought to generate interest in graduate study in materials science among well-qualified undergraduates. (KR)

Fire-fighting considerations teachers may want to raise with students in physics classes are discussed. Concepts involved in extinguishing fires and the operation of fire equipment are detailed. (CW)

Discussed are the kinetic interactions of these chemical processes and the determination of the actual order of such reactions. Included are multiple exchange, catalytic exchange with deuterium, and depletion of the original substrate. (CW)

This tutorial is intended to introduce factor and cluster analysis at a level that will afford the senior student or the practicing chemist some insights into the workings of the computer packages employing these methods, without being overwhelming with mathematical detail or process. Included are basic terms and working examples. (CW)
