The question of whether modern experiments are limited by the uncertainty principle or by the instruments used to perform the experiments is discussed. Several key experiments show that the instruments limit our knowledge and the principle remains of strictly academic concern. (DF)

Describes purpose and use of elementary school earth science field instruction sites. Scientific concept and methodology objectives are given. General principles for earth science site model selection and implementation are discussed. Operationof site model program in New York City is explained. (JM)

Herbert Simon (Nobel prize-winning economist/professor) expresses his views on human and artificial intelligence, problem solving, inventing concepts, and the future. Includes comments on expert systems, state of the art in artificial intelligence, robotics, and "Bacon," a computer program that finds scientific laws hidden in raw data.…

Discusses whether chemistry should be taught using a purely descriptive approach or using the current "principles" approach. Considers what sort of background should be provided given the uses students are most apt to make of their general chemistry training. (SK)

Presents a self-instructional package for medical students and graduate students and is intended to communicate the basics of ionic equilibria in a lecture format. The package deals with osmotic aspects of the Gibbs-Donnan Equilibrium and with ionic equilibria. (Author/SA)

Discussed is the lack of a scientific foundation and scientific evidence favoring astrology. Included are several research studies conducted to examine astrological tenets which yield generally negative results. (Author/DS)

Traces the history of the search for the ultimate nature of matter. The work of outstanding physicists since the late nineteenth century is discussed as it relates to the total picture of the search for a single unifying theory. (SA)

This article describes the Science Starts Early program, which is designed to expose young, potentially gifted children, particularly girls, to basic scientific principles that will allow them to explore the world around them. A Science Starts Early program curriculum is described and examples are provided of experiments. (Contains references.)…

Discusses some issues that have long been claimed as the exclusive province of the humanities, such as brotherhood and belonging, the sense of beauty, and the meaning of human. Suggests how a knowledge of science can contribute to understanding. (YP)

Describes a pattern of failure to apply relevant scientific principles among pupils. Tenth grade Israeli students were tested and later interviewed in order to determine areas of knowledge in which there was some question concerning knowledge of scientific principles. Suggests that teachers must involve the pupils in situations in which erroneous…

Presents some principles for specifying general classes of polymers for predicting relative chemical attack from acids, bases, oxidants, and certain common antagonists. Also discusses predicting relative solvent effects. Suggests uses of this information in two or three lectures in a chemical engineering materials course. (YP)

Discusses making a computer-simulated rainbow using principles of physics, such as reflection and refraction. Provides BASIC program for the simulation. Appends a program illustrating the effects of dispersion of the colors. (YP)
