摘要:

I read C. P. Snow’sTheTwoCulturesin 1960, when I was teaching English at Wellesley, and it made such an impression on me that I spent the next two years trying to redress the imbalance of mind deriving from a purely literary education, by taking a year of undergraduate science and then teaching for a year at a technical college. I wrote a book on the subject, calledScienceandtheShabbyCurateofPoetry, published in 1964. But in the fifteen years since then I have given only sporadic attention to the issue, though I have never forgotten it. I’ve been defeated by the problem of getting past the pious platitudes—’’it’s a crying shame that the two cultures are so divided’’—to arguments that are intellectually or any other way substantial. But now it seems to me that certain external circumstances have change enough that that problem can be resolved; not the problem of the very different experience of men in the humanities from men in the sciences, but the problem of communication between them. What follows are the 1979 reflections on the split, various in character but partly joyful, of a long‐term desponder.

摘要:

From January 29 to February 1, 1979, the American Association of Physics Teachers held its annual Winter Meeting in New York City. In this report we describe the results of an illuminative study which investigated the activities and perceptions of those who participated in that meeting. Through interviews, observations, and an assortment of questionnaires, we gathered information about many different aspects of the meeting and from many different points of view. We describe in the report who the participants were and what they wanted from this meeting. We then evaluate the various activities of the meeting in term of their effectiveness in meeting the participants’ wants. Finally, we point out and discuss a few major issues that emerged in the course of our study and were sources of conflict for many of those attending.

摘要:

We describe three different methods of visualizing the ’’closed universe’’S3, and point out language in Dante’sDivineComedywhich suggests that he visualized his universe in the same ways, making his universe topologicallyS3.

摘要:

Conditions are examined for measurement of the position and momentum of a particle by Compton scattering from various directions. In addition to the usual uncertainty relation that emerges from this analysis, it is shown that, for a given initial frequency, there is generally a critical angular aperture at which the error in position is a minimum.

摘要:

A method for the illustration of the statistical nature of measurements in quantum physics by means of simulation with pocket calculators is described. The application to examples like the double‐slit experiment, Mott scattering, and the demonstration of the uncertainty relation is discussed.

摘要:

A simple technique of holography, using only one source beam is introduced. Impressive curved holograms and rainbow holograms can be fabricated on an unisolated laboratory table with this technique.

摘要:

A simple and deep standard mathematical theorem asserts the existence, for any one‐parameter differentiable group, of an additive parameter, such as the angle for rotations and the rapidity parameter for Lorentz transformations. The importance of this theorem for the applications of group theory in physics is stressed, and an elementary proof is given. The theorem then is applied to the construction from first principles of possible relativity groups.
