Investigates a sequence of inelastic collisions resulting among three spheres, whose centers are on a line, when at the outset the leftmost sphere is propelled to the right and the other two spheres are at rest. Expressions are obtained for velocity, time, and distance variables. (MLH)

Discusses the role of copper in biological systems and metabolism. (MLH)

There is a misconception among undergraduate students that global warming is caused by holes in the ozone layer. In this study, we evaluated the presence of this and other misconceptions surrounding atmospheric chemistry that are responsible for the entanglement of the greenhouse effect and the ozone hole in students' conceptual frameworks. We…

Reports interference fringes that appear when a loaded plate of transparent non-crystalline plastic is placed between crossed polars; describes polarization of light sources and the origin of the analyzing polarizer. (GS)

This monograph was written for the Conference of the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. It is intended for students who have had an introductory college physics course. It seeks to provide an introduction to the idea of distributions in general, and to some aspects of the subject in…

This monograph constitutes the first five chapters of an introductory course in physics for students who do not intend to become professional physicists. The over-all themes and ideas of physics receive the major emphasis, with little stress placed on mathematical manipulation. The style of presentation is mainly a combination of the axiomatic and…

This monograph is a review of the quantum mechanical concepts presented in two other monographs, "The Nature of Atoms" and "Bonds Between Atoms," by the same author. It is assumed the reader is familiar with these ideas. The monograph sketches only those aspects of quantum mechanics that are of most direct use in picturing and calculating the…

This laboratory manual, containing 44 exercises, is intended to be used as part of an audio-tutorial approach to laboratory work in a life-science course for student nurses. Exercises include basic techniques of miscroscopy, microbiology, electrophysiology, routine biochemical analyses of blood and urine, and microscopic examination of prepared…

This monograph was written for the conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. The approach is phenomenological and microscopic, and is intended for college students who are not preparing to become professional physicists. The monograph has three sections. Section I includes a…

Experiments dealing with laser mode structure are presented which are suitable for an upper division undergraduate laboratory. The theory of cavity modes is summarized. The mode structure of the radiation from a helium-neon laser is measured by using a photodiode detector and spectrum analyzer to detect intermode beating. Off-axial modes can be…

Supports the contention that sliding friction explains the inversion of a tippe top when it is spun upon a flat surface. Provides a rigorous analysis of the top's mechanics, together with computer-generated solutions of its equations of motion. (MLH)

Utilization of simple experiments to illustrate a few aspects of physics in which sampling plays a crucial role. (DF)
