Corrected solutions including radiation damping are obtained from relativistically correct equations of motion for a free electron in a plane electromagnetic wave. (SL)

Describes the treatment of hard-core potentials (nucleon-nucleon interaction) in quantum mechanics. (SL)

Defines and investigates a moment of inertia tensor for a quantum mechanical wave packet. (SL)

Presents an operator which transforms quantum functions to solve problems of the stationary state wave functions for a particle and the motion and spreading of a Gaussian wave packet in uniform gravitational fields. (SL)

Presents a completely arithmetic development of Newtonian dynamics in which all classical conservation laws are valid and all equations are in forms amenable to high-speed digital computer computation. (SL)

Describes a slide rule which can be used to simplify the quantum mechanics of half-integral spin. (SL)

Describes a study investigating the combined effect of certain variables on student achievement in classical mechanics. The purpose was to (1) describe preinstructional knowledge and skills; (2) correlate these variables with the student's success in learning classical mechanics; and (3) develop hypothesis about relationships between these…

Presents a derivation of the minimum possible bandwidth of a laser oscillator. (SL)

The Boyle-Mariotte gas law was formulated in terms of pneumatic springs," subsumed by Hooke under his own stress-strain relation, and generally regarded as a law of elasticity. The subsequent development of Boyle's principle and elasticity provide thought-provoking test cases for Kuhn's notations of paradigm and puzzle solving in physics.…

Presents data from 10 years of teaching using Peer Instruction (PI) in calculus- and algebra-based introductory physics courses for non-majors. Results indicate increased mastery of both conceptual reasoning and quantitative problem solving upon implementing PI. Discusses ways to improve the implementation of PI. (Contains 34 references.)…

Derives the general Doppler formula in a nonstatic universe using assumptions of special relativity, homogeneity and isotropy of the universe. Examples of applications to physical cosmology are given. (SL)

Studies the role of context in students' uses of alternative conceptual models by using Newton's third law. Identifies four contextual features that are frequently used by students in their reasoning. Probes the effects of specific contextual features on student reasoning using a multiple-choice survey. (Contains 39 references.) (Author/YDS)

Uses the Dresden and Feiock quantum mechanical Kac ring pedagogical model to illustrate formal results and approximation limitations of nonequilibrium statistical mechanics. (SL)
