摘要:

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 in 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. Such communications should be sent to Professor Joel Gordon, Chairman, Resource Letter Committee, Department of Physics, Amherst College, Amherst, Massachusetts.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 CR-1 and enclose a stamped return envelope.

摘要:

By means of a series of arguments, a general Lorentz transformation is derived in the infinitesimal. This gives the generators of the group, and exponentiation produces a finite transformation.

摘要:

The basic ideas of theSU(3) symmetry model of strongly interacting particles are explained in a manner that should make the presentation clear to anyone who has had a course in ordinary quantum mechanics.

摘要:

Ice is melted by electrical heat supplied to a constant-temperature calorimeter. The amount of ice melted is obtained by observing the change in volume of the system at constant pressure. The determination of the latent heat is precise to within ±1%. In a less precise variation, supercooled water is allowed to freeze and the latent heat is determined from the expansion of the system and the amount of warming which occurs. Students react to the phenomenon with surprise; although the precision is poor, the supercooling experiment is a very effective teaching device.

摘要:

A simple method is given for finding the terms obtained from a configuration containing a number of equivalent electrons. This method is based entirely upon two facts: (1) the Pauli principle prevents any two electrons from having the same quantum numbers; and, (2) one and only one completely antisymmetric wavefunction can be constructed from any given set of allowed quantum numbers. Because of its simplicity, both in concept and in application, this system is well suited to presentation to undergraduate students of modern physics.

摘要:

The design and construction of a simple hydrostatic-pressure system suitable for the undergraduate laboratory are described. Operation of the apparatus is illustrated by measurements of the effect of pressure on the dielectric constant of several liquids. The system can be used for a wide range of advanced undergraduate experiments, an assortment of which is suggested in an appendix.

摘要:

The Kronig-Penney model for the electron potential in a crystal is discussed for a simple cubic lattice. The model is adapted to a semiconductor, and it is shown that quantities such as effective mass and optical absorption coefficients near the absorption edge may be calculated.

摘要:

This paper deals with the problem of the interpretation of quantum mechanics, the nature of physical theory, and the future of physics. First, the question of why there are so many different interpretations of quantum mechanics proposed and accepted by outstanding quantum experts is treated. This requires a discussion of the relation between physics and philosophy and drawing a distinction between aphysical formalismand aphysical explanation. The Copenhagen interpretation is considered, criticized, and found to be unsatisfactory in some respects. Finally, an interpretation that contains ideas from previous interpretations but which may itself be new, is proposed. Hopefully, this is superior to the previous interpretations. It has, I believe, the advantage of logical clarity. In the process of doing this, I introduce a theory of levels of physical theory, according to which microscopic physical theory, as it develops in successive stages, becomes more and more adaptable to explaining—or at least taking cognizance of—fundamental biological or ultimately psychological phenomena.
