Presents a brief biography of Sir Isaac Newton, lists contemporary scientists and scientific developments and discusses Newton's optical research and conceptual position concerning the nature of light. (JR)

Discusses how handedness at one level may give rise to handedness at another. Presents examples from plants and animals, molecules, atoms, to elementary particles. Examines the chiral symmetry in life and when it starts. (YP)

Points out that large earthquakes can take place not only on faults that cut the earth's surface but also on blind faults under folded terrain. Describes four examples of fold earthquakes. Discusses the fold earthquakes using several diagrams and pictures. (YP)

Examines evolutionary trends, specifically trends in size, complexity, and fitness. Notes that documentation of these trends consists of either long lists of cases, or descriptions of a small number of salient cases. Proposes the use of random samples to avoid this "saliency bias." (SR)

This paper deals with a number of conceptual and theoretical issues that underlie the proposal to employ narrative explanations in science education: What is narrative? What is explanation? and What is narrative explanation? In answering these questions, we develop a framework of narrative elements and characteristics of narrative explanations.…

This paper conveys information about a Physics laboratory experiment for students with some theoretical knowledge about oscillatory motion. Students construct a simple pendulum that behaves as an ideal one, and analyze model assumption incidence on its period. The following aspects are quantitatively analyzed: vanishing friction, small amplitude,…

Presents information on the properties and largest spirals of the Local Group galaxies. Explains the three categories of galaxies, identifies the brightest members of the Local Group, and discusses recent discoveries within the group. (ML)

Promotes the study of ancient rocky shores by showing how they can be recognized and what directions future research may follow. A bibliography of previous research articles, arranged by geologic period, is provided in the appendix to this paper. (CW)

Discusses the technology used for transduction between electrical and acoustical signals. In particular, the recent developments in microwave ultrasonics research are presented. (JP)

Reviews the Hafele-Keating experiment on relativistic changes in eastward and westward moving cesium atomic clocks. Recommends the use of the Sagnac effect to remove the east-west time asymmetry and of the general-relativistic effect to elucidate the clock-rate changes. (CC)

Critical analysis is a legitimate aspect of scientific development. Examination of the limitations of behavioristic theory in its passage to therapeutic practice and the nonexplicit supplementary mechanisms inherent in the latter generates several such propositions, four are presented. (Author/CG)

Discusses the master equation of a stochastic model in chemical process systems. Presents a solution technique known as the System Size Expansion. (YP)

Describes Neptune through Voyager 2 including the discovery, location, atmosphere, ring arcs, radiation, two satellites, and Voyager's goals. Provides several diagrams and pictures. (YP)

Traditionally nuclear chemistry appears in the last few chapters of chemistry textbooks and is not normally considered a mainstream topic. In addition, some science teachers lack the training or equipment to teach nuclear chemistry. Yet nuclear chemistry is a very important topic that should be taught in all chemistry classrooms. Learning about…

Chemistry Is in the News (CIITN) is an innovative project aimed at enhancing higher-order cognitive skills (HOCS) via connecting university-level chemistry to everyday life and real-world issues. The CIITN project and its related Web tools were presented in a workshop to illustrate their conceptual framework, educational potential, and…
