摘要:

Although in 1919 I was an undergraduate at the University of Wisconsin, my parents properly felt that it would be a salutary experience for me to spend a summer on another campus. At that time, the University of Chicago had the preeminent graduate summer school in physics; so I went there at the end of my junior year, and took as part of my program a course in optics under Professor Michelson. Although he was 67 years old, he was vigorous both mentally and physically, even playing tennis at the Quadrangle Club. He had a pedagogical system of his own. There was no final written examination; instead, every week he would interrupt his lectures to send some quivering student to the blackboard to explain a topic that he, Michelson, had previously presented. This system has much to be said in its favor. It insures that the students keep abreast of the lecture material and are clear in their exposition. I can remember that when Michelson felt the presentation was not lucid, he made some such remark as, “How would you expect a beginner to understand what you are saying?”

摘要:

One of the objectives of nuclear physics is to acquire a better understanding of nuclear forces. The understanding of nuclear forces can be enhanced by investigations of the effects of the nuclear spins of the interacting particles. To make such investigations when protons are interacting with nuclei, one wishes to have available a beam of protons whose spins are oriented in a chosen direction, i.e., a beam of polarized protons. By scattering these protons from nuclei, one can investigate the nature and strength of the spin‐orbit force which is required by most phenomenological theories of the nucleus, particularly the shell model.

摘要:

The Ultrasonics Symposium seems now to be well established as an annual affair. The 1963 event, held on December 4, 5, and 6, at the Marriott Motor Hotel in Arlington, Va., fully met the high standard set in the previous year. These symposiums, of which the first was held in 1958, are sponsored by the IEEE Professional Technical Group on Sonics and Ultrasonics, which owes its unwieldy name partly to the merger of the American Institute of Electrical Engineers with the Institute of Radio Engineers and partly to its own recent resolve to extend its field of interest from ultrasonics to all sonic phenomena not communicating intelligence to the human ear.

摘要:

The first international conference on luminescence ever to be held took place in Poland in 1936. This was pointed out at the opening of the 1963 International Conference on Luminescence last September 25 in Torun, Poland, by Alexandra Jablonski, president of the Organizing Committee, and the man after whom the diagram used by every worker in the field of luminescence is named. As for the appropriateness of Torun for an international scientific congress—Torun is the birth‐place of Copernicus. The meeting was held in the Nicholas Copernicus University.

摘要:

Your article inPhysics Todayon “Scientific Choice” touches some of the most important questions which we will face in the immediate future. You presented the situation in the clearest possible way and you pointed out the terrible difficulties which are inherent in any form of scientific planning. I agree with most of what you are saying and I like the way in which you said it. There is one important point, however, in which I cannot follow you. I accept your three “external criteria” for scientific choice: technological merit, scientific merit, and social merit. I would even go along with your sharper definition of scientific merit, when you propose that “…other things being equal, that field has the most scientific merit, which contributes most heavily to and illuminates most brightly its neighboring scientific disciplines”. But I cannot follow your arguments when you apply your criteria to the field of high‐energy physics.

摘要:

A Physics Survey Committee has been organized within the Division of Physical Sciences of the National Academy of Sciences—National Research Council to study future requirements for the support of physics in relation to national needs and to the rest of science. The Committee will seek to identify the most significant research problems in various subfields of physics, as a basis for estimating levels of support necessary to assure the balanced development of the field as a whole over the next five to ten years.

摘要:

On the occasion of its 101st annual meeting in Washington, D.C., the National Academy of Sciences presented its Cyrus B. Comstock Award to Chien‐Shiung Wu of Columbia University. The award, which is given every five years by the Academy for the most important discovery or investigation in electricity, magnetism, or radiant energy, paid tribute to Dr. Wu's work in providing the first experimental confirmation of the violation of parity.
