Addresses questions of the philosophy of computer use that cut across various specialities, providing examples to make these distinctions clear. Topics considered include numerical analysis, simulations, software, Fortran computer language, and hardware. Indicates that computers do more than analyze experimentors' data. (JN)

Experimentalists in particle physics have long regarded computers as essential components of their apparatus. Theorists are now finding that significant advances in some areas can be accomplished only in partnership with a machine. Needs of experimentalists, interests of theorists, and specialized computers for high-energy experiments are…

Discusses contributions of computers to research in magnetic and inertial-confinement fusion, charged-particle-beam propogation, and space sciences. Considers use in design/control of laboratory and spacecraft experiments and in data acquisition; and reviews major plasma computational methods and some of the important physics problems they…

Discusses a revision of existing respiratory physiology simulations to promote active learning experiences for individual students. Computer graphics were added to aid student's conceptualization of the physiological system. Specific examples are provided, including those dealing with alveolar gas equations and effects of anatomic shunt flow on…

Suggesting that the evolutionary record may be written in proteins and genes, discusses research in which species are compared by immunology, DNA, and radioimmunoassay. Molecular studies show that DNA from humans and chimps is 98 percent identical, a degree of similarity usually occurring only among animals of the same genus. (JN)

Examination of selected material from the history of science can provoke a number of questions about the nature of that activity as indicated in part 1 (SE 533 400). Presented here are some guidelines to help teachers discuss the observation statements and kinds of questions raised in part 1. (JN)

The Mole Concept is a learning cycle (patterned after University of Nebraska-Lincoln's ADAPT model) for the chemical unit "mole." Discusses objectives and activities involved in each phase of the cycle: exploration, invention, and application. Indicates the cycle is superior to traditional lecture-demonstration for teaching the abstract mole…

Describes an experiment in which static/dynamic properties of a helical, steel spring are investigated. During the experiment students discover that the behavior of the springs is non-Hookean at small loads. Background information (including static deflection and period of oscillation) and typical results are provided. (JM)

Understanding the complex stratigraphic/structural relations produced during accretionary events is best achieved through "terrane analysis," wherein individual structural domains are discriminated and their geologic histories compared and analyzed for critical, paleogeographical significant information. Terrane analysis methodology,…

Provides a general description of a preprogramed, microprocessor-based laboratory instrument, discussing its use in monitoring: (1) environmental changes; (2) distribution of count rates from a radioactive source, and (3) motion on an air tract. Includes list of the instrument's various capabilities: frequency meter, voltmeter, interval timer, and…

In response to a question, "Why not use a magnetic or electric field to deflect light?," reviews the relation between electric charge and electric/magnetic fields. Discusses the Faraday effect, (describing matter as an intermediary in the rotation of the place of polarization) and other apparent interactions of light with electric/magnetic fields.…

Results from two surveys of chemists and educators conducted at two conventions indicate weak spots in facilities, poor storage information, and failure to take precautions against reactive hazards. Includes suggestions and a checklist related to a wide range of storage problems. (SK)

Background information and laboratory procedures are provided for an undergraduate experiment requiring students to prepare a coordination compound. (SK)

Describes an advanced simulation illustrating how basic engineering skills can be combined with economic considerations and risk-taking judgments to effectively design and operate a chemical processing unit in a competitive environment. The simulation is used as one of five projects in a technical management course. (SK)

The possibility of changing the prosaic style of college level science textbooks to increase readability was investigated. Conclusions suggest that the readability of college textbook prose is not significantly affected by the stylistic factors employed in most readability formulas. (CJ)
