摘要:

In physics, as in professional occupations in general, there has been up to the present time very little information as to the incomes which members of the profession can expect to earn during their working lives, and the influence on their earnings of such factors as educational background, experience, and type of employment.

摘要:

Man has been studying the magnetic field of the earth for centuries. The existence of this field of force must be deduced by the use of scientific instruments since, unlike gravity, it is not detectable by our human senses. Measurements of the Earth's magnetic field have been made from deep down in mines up to nearly one hundred miles above the surface.

摘要:

For nearly six years there has been in existence at the California Institute of Technology a program of research work directed at increasing the precision of all measurements in nuclear spectroscopy and especially the precision with which nuclear energy levels may be determined. This trend toward higher precision of measurement is to be observed at present in nearly every area of nuclear physics (except possibly in the still new very high energy field) for it is generally realized that, while much primary qualitative information has been acquired, a real understanding and interpretation of the problems of nuclear structure and the internal mechanics of nuclei must wait for a sufficient fund of accurate and reliable quantitative numerical data to furnish a foundation for theory to build upon.

摘要:

The Atomic Energy Act of 1946 provides in Section 2(b) that “There shall be a General Advisory Committee to advise the Commission on scientific and technical matters relating to materials, production, and research and development, to be composed of nine members, who shall be appointed from civilian life by the President.” The Act further directs that “The Committee shall designate one of its own members as Chairman. The Committee shall meet at least four times in every calendar year.” Beyond that, the Act does not specify how the Committee is to perform its advisory functions, how it is to obtain the information and analysis on which to base its advice, nor how to determine the issues to which it should direct its attention.

摘要:

A number of new facilities and improvements in the high‐altitude laboratories in Europe have been instituted recently, the most significant of which we shall recapitulate, since they may be of interest to colleagues from other countries desirous of making use of them.

摘要:

The origin of the aurora borealis, a subject of much speculation and scholarly debate, may quite plausibly be ascribed to proton and alpha particle bombardment of the upper atmosphere, according to Aden B.

摘要:

The National Science Foundationhas contracted with the National Academy of Sciences for a broad survey to determine the nature and extent of research and of teaching in applied mathematics in the United States. The survey, to be carried out with the cooperation of the Office of Naval Research, the Office of Ordnance Research of the Army, and the Office of Scientific Research of the Air Force, is expected to take one year. As part of the study, a conference on training and research needs in applied mathematics will be held during the spring of 1953 to consider the findings of the survey and to examine the future of research and teaching in the field. Data and recommendations of the survey and the conference will be made available to all agencies.
