Presents new least-squares algorithms that update a fit after each point is entered so trends can be detected promptly as an experiment proceeds. (MLH)

Analyzes simple electrical circuits, showing that for high frequencies they have frequency and time responses identical to the spontaneous radiative decay of atoms. Compares a two-circuit electrical system with a two-level atom. (MLH)

Discusses ways to improve physics curricula, such as including events from science history and using discovery techniques. (MLH)

Provides directions for constructing graphical alignment charts to solve a variety of mathematical physics problems. (MLH)

Outlines a selection of demonstrations for teaching color science to students of science, fine arts, and interior design. (MLH)

Examines the geometrical interpretation of the vector operation curl for vector fields "A" such that "A" dot curl "A" is not equal to zero. (MLH)

Shows that radioactivity is a binomially distributed process, based on a probability equation approach, for any value of the observation time. (MLH)

Describes a belt hook that is both functional and can be used to demonstrate the center of gravity. (MLH)

Presents a translated reprinting of an article that appeared in a Russian scientific journal in 1971 about some life incidents and beliefs of the physicist Landau. (MLH)

Discusses theories and research concerning the radiation produced by electrons when they are accelerated centripetally in particle accelerators. (MLH)

Describes how physics concepts can be taught by relating them to pleasant experiences. (MLH)

Describes an experiment in which chemistry students determine the efficiency of a laboratory burner used to heat water. The reaction is assumed to be the complete combustion of methane, CH4. The experiment is appropriate for secondary school chemistry students familiar with heats of reaction and simple calorimetry. Contains pre-laboratory and…

Three studies investigated the analogical reasoning of 127 children in a physics task using an analogy generated by the children. Found that 9- to 10-year olds showed spontaneous transfer in both negative and positive analogy training conditions, while 7-year olds showed no transfer in the positive analogy condition but transferred only selected…

Describes the use of a bell in the classroom to demonstrate the phenomena of beats and resonance. Explains properties of the bell, and its use in place of a demonstration with a spring is discussed. (PVD)

Describes an approach to teaching atomic, nuclear, and particle physics using the history of the most important discoveries in that field. Uses the manuscripts, first publications, measurements and data of initial discoveries, and the photos of apparatus and of famous physicists to arouse student interest. Presents examples from the life and work…
