Prepared at the request of the AAPT Committee on Resource Letters; supported by a grant from the National Science Foundation.This is one of a series of Resource Letters on different topics, intended to guide college physicists to some of the literature and other teaching aids that may help them improve course contents in specified fields of physics. No Resource Letter is meant to be exhaustive and complete; in time there may be more than one letter on some of the main subjects of interest. Comments and suggestions concerning the content and arrangement of letters as well as suggestions for future topics will be welcomed. Please send such communications to Professor Joel E. Gordon, Chairman Resource Letter Committee, Department of Physics, Amherst College, Amherst, Massachusetts 01002.Notation: The letterEafter an item number indicateselementarylevel, useful principally for freshman liberal arts through sophomore physics courses; the letterIindicatesintermediate(junior, senior) level; and the letterAindicatesadvancedmaterial principally suited for senior, graduate study. An asterisk (*) indicates items particularly recommended for introductory study.Additional copies: Available from American Institute of Physics, 335 East 45 Street, New York, New York, 10017. When ordering, request Resource Letter SAP-1 and enclose a return envelope.

摘要:

The Robert A. Millikan Lecture Award is made annually to a physicist chosen by a special committee of the American Association of Physics Teachers because of his creative and imaginative contributions to the teaching of physics. The lecturer selected is one whom the Association wishes to honor at the Summer Meeting in the same way that it honors the Oersted Medalist at the time of the Annual Meeting. The award is made possible through the annual support of of Prentice-Hall, Inc.; the first award was made in 1964.The recipient of this award for 1966 is Alan M. Portis, Professor of Physics at the University of California at Berkeley.The four-year development of the Berkeley Physics Laboratory is described starting from its inception in the Summer of 1962. Reasons for the special attention given to electrons and photons are presented. The use of student groups in the laboratory trials is discussed. The wide response to the laboratory is analyzed. Finally, modifications currently being made in the Laboratory by the Berkeley Physics faculty are presented and discussed.

摘要:

America's leading physicist of the midnineteenth century made his major research contributions while employed full time as a science teacher. A study of Joseph Henry's unpublished correspondence and laboratory journals and the lecture notes of his students reveals the background of his career as a physics professor at Princeton in the 1830's and 1840's. These documents display a reciprocal and mutually advantageous structuring of Henry's lectures and research, which expanded the scope and increased the effectiveness of each. This close interconnection between teaching and research was established by Henry at a time when the research function of the college professor had not yet been accepted.

摘要:

A detailed discussion of nongeometric, or “accidental,” degeneracy is presented in the context of Newtonian, relativistic, and quantum mechanics. An analogy with broken symmetries in elementary-particle physics is used to present an elementary discussion of certain recent developments in theoretical high-energy physics.

摘要:

Adapting an argument by Dyson in quantum electrodynamics, we point out that the attractive and long-range character of the gravitational interaction may seem to prevent the universe from being stable against decay into successively lower energy states. A straightforward solution to this paradox is given, based on the essentially nonlinear nature of gravitational theory. This nonlinearity, whose importance is thus clearly demonstrated, is shown to have a a very elementary origin. A simple approximation, incorporating the nonlinear effects in a physically transparent way, quantitatively substantiates our intuitive argument.

摘要:

The usual expressions for the Compton effect are based on the assumptions that the scattering electron is free and stationary. These assumptions are reasonable when the photon energy is large compared to the electron binding energy; however, in many situations this is not the case, and the binding energy and momentum of the electron alter Compton scattering by causing (1) line broadening, (2) a discrete spectrum, (3) a line-shift defect, (4) a decrease in incoherent scattering at low angles, (5) an increase in coherent scattering at low angles, and (6) a change in recoil electron distribution. These effects are described, and differential and average cross sections for carbon are calculated on the Thomas-Fermi model to illustrate them quantitatively.

摘要:

An electric network is presented in which the energy density is distributed in three-dimensional space in the same fashion as the probability density waves for a spinless particle in any given potential field. The network is of interest in that it can be easily realized physically.

摘要:

This article discusses the problem of the water flask with several unequal holes in the bottom by considering it as a nonlinear work problem which can, nevertheless, be solved by elementary considerations. It is described as a suitable fluid-mechanics experiment for elementary courses, and it is then solved analytically—first without the calculus and then with the help of the calculus. It is the solution without the calculus which is of particular interest for non physics majors, because of its comparative simplicity and lack of cumbersome equations.

摘要:

The kinematics of special relativity is depicted through space-time diagrams, whereby the Lorentz transformation as well as the Galilean can be presented in graphical form rather than analytic. The space-time diagrams are then used to formulate and explain several of the paradoxes of special relativity. The method is a variation of the Minkowski diagram. The reference axes are kept fixed, and the space-time point undergoes an apparent displacement in the plot as the observation frame is changed. The graphical analysis is semiquantitative for some problems and is quantitative for others.
