Presents a combined knowledge of both the chemistry and physics of amorphous conductors in an attempt to understand these unconventional solids. (CS)

Diagrams and tables supplement textual information regarding the structure of ScNbo-4 and its observed and calculated d-values; excitation and emission spectra and cell constants for the ScTa(1-x)NB(x)O(4) system. (CS)

Compares neutrino and photon emissions, develops the thermodynamic blackbody laws of neutrino emission analogous to laws governing photon emission, points out that combined radiation from a "true blackbody" consists of both photon and neutrino emissions of comparable magnitude, and speculates upon the existence of blackbody neutrino…

Describes several simple experiments that can be used to observe directly the dispersion curve of plasmon surface polaritons (PSP) on flat metal surfaces. A method is described of observing the increonental change in the wave vector of the PSP due to coatings that differ in thickness by a few nanometers. (Author/CS)

Presents equations and techniques for calculating and interpreting many of the spectroscopically important parameters associated with the ground and second excited states of the iodine molecule. (Author/CS)

Guidelines are presented to help the classroom science teacher effectively deal with handicapped students. (SA)

Provides background information, defining areas within organ systems where physiological waterfalls exist. Describes pressure-flow relationships of elastic tubes (blood vessels, airways, renal tubules, various ducts). (CS)

Discusses the concept of time in relation to the age of the chemical elements and the age of the universe. (MLH)

Discusses theories about the possibility of the weakening or strengthening of the gravitational constant, and the cosmological effects of such a change. (MLH)

Discusses the renewed interest in superconductivity research and describes the differences between the two basic types of superconductivity. (MLH)

Discusses a new branch of optical spectroscopy that deals with the optical analogs of spin transients and provides ways to explore dynamic interactions in optically excited materials. (MLH)

Describes resources for information and activities involving volcanoes. Includes an activity that helps students become familiar with the principal types of volcanoes and explores how the viscosity of magma affects the way a volcano erupts. (MKR)

Shows how the thermal power developed by friction is exactly half the supplied power in the general case of a variable force of friction. Investigates the mechanism whereby one-half the input energy is dissipated as heat using mathematical expressions. (YP)

Discusses doing science experiments on a small scale in order to reduce the quantity of chemicals used in science classes. (MKR)

Features science concepts with accompanying activities teachers can use in the classroom. Presents a lesson in optics that utilizes optical illusions to illustrate scientific points and allows students to use the following processes: observing, communicating, controlling variables, hypothesizing, and gathering and interpreting data.
