Explains an error that occurs in calculating the conditions for a maximum value of a rate expression for a bimolecular reaction. The rate expression is derived using the Langmuir adsorption isotherm to relate gas pressures and corresponding surface coverages. (GS)

Presents a multipart experiment utilizing the same two compounds in preparation, interpretation of infrared spectra, and kinetic study. Several extensions of the experiment are included. (SLH)

This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. It is intended for use by college students who are non-physics majors. The approach is phenomenological and macroscopic. The monograph contains three chapters. Chapter 1 discusses Faraday's experiments…

This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. The measurement of very small distances and sizes, and the concept of models are discussed in the introduction. The optics of slits is dealt with in chapter 2. Chapter 3 presents the optics of holes.…

This document is a monograph intended for advanced undergraduate students, or beginning graduate students, who have some knowledge of modern physics as well as classical physics, including the elementary quantum mechanical treatment of the hydrogen atom and angular momentum. The first chapter introduces symmetry and relates it to the mathematical…

The rationale of audio-tutorial instruction is discussed, and the history and development of the audio-tutorial botany program at Purdue University is described. Audio-tutorial programs in geology at eleven colleges and one school are described, illustrating several ways in which programs have been developed and integrated into courses. Programs…

This supplementary text material is meant to suggest ways in which the computer can increase students' intuitive understanding of fields and waves. The first way allows the student to produce a number of examples of the physics discussed in the text. For example, more complicated field and potential maps, or intensity patterns, can be drawn from…

The field of inquiry into how atoms are bonded together to form molecules and solids crosses the borderlines between physics and chemistry encompassing methods characteristic of both sciences. At one extreme, the inquiry is pursued with care and rigor into the simplest cases; at the other extreme, suggestions derived from the more careful inquiry…

Discusses the quantization of angular momentum components, Heisenberg-type inequalities for their spectral dispersions, and the quantization of the angular momentum modulus, without using operators or commutation relations. (MLH)

Discusses the Stark effect of the plane rotator using a simple analysis of symmetry features and a careful application of degenerate perturbation theory. (MLH)

Discusses the construction of wave packets by superimposing bound-state eigenfunctions. Illustrates the infinite square well and the infinite square well with a delta-function barrier. (MLH)

Discusses the uses of the Gelfand-Levitan formulation of the inverse problem as a source of exactly solvable bound-state models that are suitable for examples in quantum mechanics courses. (MLH)

Discusses textbook errors concerning the stopping potential and the work function of the collector in Millikan's experiments on the photoelectric effect. (MLH)

Discusses symmetry elements of molecules, symmetry operations, and point groups. Gives ten examples of assigning a point group to a molecule. (MLH)

Presents a simple demonstration of optical activity and a simple method to show crystalline growth. (MLH)
