摘要:

THE THIRD ANNUAL REPORT of the National Science Foundation, transmitted to the White House in November and sent by the President to Congress in January, summarizes the Foundation's activities for the 1953 fiscal year, which ended last June 30th. The total cost of NSF operations in 1953 was $4.43 million, of which almost seventy‐five percent was used for research grants and for fellowships. Most of the remainder was spent on national science policy studies, a review of the research and training programs, dissemination of scientific information, and attendance at international scientific meetings.

摘要:

ADDITIONAL BASIC RESEARCH, President Eisenhower told Congress, “is needed to build up the fund of knowledge on which will be based the development of new crops for agriculture, new methods of safeguarding health, new tools for industry, and new weapons. A further important result is the training which basic research projects provide for graduate students in our universities. The number of trained scientists graduating each year falls short of the needs of our growing economy and is still declining. Enlargement of the research program and the related fellowship program will help counteract this trend.”

摘要:

THE TIMETABLE OF EVENTS that occurred during the first moments of the expansion of the universe is discussed in some detail by Ralph A. Alpher, James W. Follin, Jr., and Robert C. Herman, all of the Applied Physics Laboratory, Johns Hopkins, in their article, “Physical Conditions in the Initial Stages of the Expanding Universe”, which has appeared in the December 15thPhysical Review.

摘要:

Nature abhors a vacuum, the ancient physicists told us. And judging from the modern quantum theory of the vacuum it is not very surprising. Indeed, since Dirac propounded his theory of the electron, there have appeared many papers in which the properties of the vacuum have been discussed in terms of very complicated (and sometimes divergent) integrals. Instead of being the simplest problem in the world, the motion of a free electron in a vacuum appears to be an extremely complicated phenomenon. Instead of being an elementary nothingness, like the antithesis of Hegel's “Being” or that which Torricelli would have produced with a perfect pump, the vacuum of quantum electrodynamics can “fluctuate”, can be “polarized”, and can contain “negative energy electrons”. What is worse, its fluctuations and polarization are infinite and the number of negative energy electrons is infinite also.

摘要:

Is there any point in trying to make a case for physics research in a small college? Isn't all of the really important research which needs to be done now being carried on in the universities and in the large government and industrial laboratories, where the extensive and costly facilities and necessary manpower are available? What role does the small college play in fulfilling the urgent need for increasing the national scientific potential? These are the basic questions which the recently held Conference on Physics Research in Colleges tried to answer.
