摘要:

This gathering, not an ordinary session concerned with scientific research, is devoted to appraising and evaluating the general spirit of high‐energy physics. We hope to bring to the surface the reason it is an important field of science—the reason it should continue to receive support in something like the exponentially growing rate that it has in the past.

摘要:

We know that there are two frontiers in the study of the basic laws of natural science: the frontier of the very large, the cosmos, and the frontier of the very small, the structure of the elementary particles out of which the entire universe is constructed, including us. The combination of these two (at the present time theoretically unrelated, although we hope that this situation won't persist) gives us the basic scientific laws that form the foundations for our discussions of science. The research in both of these fields is necessarily a close partnership of theory and observation, and the availability of numerous experiments in the study of the very small is what has made progress in that field more rapid and more exciting in recent years than progress at the other end. But, as interesting observations of the cosmos accumulate, cosmology too should flourish. One thing that makes the adventure of working in our field particularly rewarding, especially in attempting to improve the theory, is that at this basic level of science a chief criterion for the selection of a correct hypothesis, even more than elsewhere in science, seems to be the criterion of beauty, simplicity, or elegance.

摘要:

My instructions this morning were to give a survey of the subject we call elementary particle physics, emphasizing the experimental aspects. I will choose what I believe to be interesting and exciting and try to see how we got where we are. The objects we call elementary particles have changed over the years and Fig. 1 is meant to illustrate this.

摘要:

We are here today to discuss the means by which the development of advanced accelerator facilities can best implement the further exploration of highenergy phenomena. I shall refrain from showing a chart of the type that purports to indicate, by a double‐logarithmic plot of available energy vs time, that accelerators of increasingly high energy areinevitable. We might, however, recall the recommendations that the Ramsey Panel submitted a year ago to the Atomic Energy Commission's General Advisory Committee and to the President's Office of Science and Technology. Figure 1 is adopted from a similar diagram in the report of this Panel, whose recommendations with respect to the new facilities required to insure continued progress in high‐energy physics clearly attached highest importance to advancement of the “energy frontier.”

摘要:

C. N. Yang:We have just heard three speakers describing to us various problems which arise in theoretical and experimental high‐energy physics, and in the designs of high‐energy accelerators. The problem of the aims, prospects, and the impact of the whole enterprise is a very complex subject. I shall confine myself to a few remarks concerning the historical aspect of the subject. High‐energy physics is a natural continuation of the traditional efforts by physicists to study the structure of matter. By all standards of comparison, I think we are not exaggerating when we say that achievements in this line of research have been most spectacular in the past sixty years. At the turn of the century, physicists, as we recall, were just looking at the structure of atoms. Thirty years later, the subject of studies progressed to atomic nuclei, and today we are looking at subnuclear constituents. The increase in energy is equally impressive; in fact, perhaps even more so. We have progressed from a few electron volts to millions of electron volts to today's multibillion electron volts. Reviewing the progress of the experimental techniques that have made possible these investigations, one is deeply impressed by the power and the ingenuity that were brought to bear at each stage of this development. With the greatly awakened interest in science in all nations, with the rapid progress of technology, there seems to be little doubt that new experimental techniques will be developed to meet every new challenge encountered in this enterprise. The impact of these developments on technology, on human affairs, and on other sciences has been important beyond description.

摘要:

High‐pressure research has undergone a considerable expansion in the past decade, particularly in the areas of physics, geophysics, and geochemistry, and in industrial chemistry. This expansion has been motivated in part by the successful industrial synthesis of diamond, in part by the increased emphasis on experiment in the earth sciences, and in large part by realization of the possibilities of performing experiments with interatomic distance as a prime variable.
