Describes various movement activities through which young children may discover topological relationships which provide a foundation for their growing understanding of space. (CM)

A basic scheme for scientific theorizing is presented. Subtopics include: (1) the plausibility of model; (2) mathematical formulation; and (3) dangers of models. (MDR)

The author illustrates and discusses some critical barrier phenomena, such as the optics of mirrors and heat and cold, which most people have difficulty extending beyond an everyday understanding. (Author/MA)

This article describes the work of the Royal Academy of Science and the Royal Academy of Spanish in developing current scientific and technical vocabulary. (NCR)

Demonstrates erroneous results obtained if change in a vector under parallel transport about a closed path in Riemannian spacetime is made in a complete circuit rather than just half a circuit. (Author/SL)

Reviews the debate between physicists Compton and Millikan over cosmic radiation in the 1930's and the resultant social repercussions against science. (SL)

Harlan Smith, chairman of the University of Texas's Astronomy Department, discusses a mobile lunar laser ranging station which could help determine the exact rates of movement between continents and help geophysicists understand earthquakes. He also discusses its application for studying fundamental concepts of cosmology and physics. (Editor/RK)

Considers the different analogies used by James Rettie, Teilhard de Chardin, Robert Ardrey, Jacob Bronowski, Richard Leakey, Steven Weinberg, Heinz Pagels, and Carl Sagan to make concepts related to time and natural history accessible to the layperson. Suggests that these analogies be used at the undergraduate level in both humanities and science…

Scientific terms and names included in "Cultural Literacy: What Every American Needs to Know" are analyzed and geology related terms are listed. Some items not listed are considered. (RH)

Examines research related to the retina's coding of visual input with emphasis on the organization of two kinds of ganglion cell receptive fields. Reviews current techniques for examining the shapes and arrangement in the retina of entire populations of nerve cells. (ML)

The author states that two costs will be involved in the coming change in technology education: financial and personal. He questions what group of educators will teach technology education in the future. (CH)

Discusses recent advances in the study of mammalian immunology. Explains the roles of two families of lymphocytes, the B cells and T cells. Also examines evolutionary mechanisms related to the immune system. (ML)

A variety of problems, ranging from vocabulary to pre-existing belief structures, prevent efficient learning among biology students. Several of these problems are discussed, with implications for teaching college level biology addressed. (JN)

Discusses a number of significant persons and ideas in the European development of notions relating to faunal succession. Major focus is on the 17th through the 19th centuries, from the onset of rational investigations of the earth to definition of the stratigraphic zone. (JN)

More than five hundred chemistry/science text books from a variety of countries and written at all levels of education have been looked at to see how they dealt with the topic of physical and chemical change. Textbooks have continued to cover this chemical topic for over one hundred years. What evidence do school textbooks contain about the…
