摘要:

On May 6th a bill was introduced in the House of Representatives calling for the establishment in the executive branch of the Government of an independent agency to be known as the “National Physical Sciences Laboratories” and having all of the present functions and responsibilities of the National Bureau of Standards. The bill, H. R. 5043, was introduced by Representative DeWitt S. Hyde (R., Maryland) and has been referred to the House Committee on Interstate and Foreign Commerce.

摘要:

A 263‐page document on the present scientific and professional manpower situation in the United States has been submitted to the White House by the National Manpower Council, a nonprofit survey group established two years ago at the Columbia University Graduate School of Business by General Eisenhower to provide a continuing appraisal of the nation's manpower problems and policies in a period of enduring emergency. The Council was supported by a grant from the Ford Foundation. Warning that “scientists and professional people cannot be stockpiled like commodities against future shortages”, the Council examined in detail the problems of providing sufficient engineers, physicists, teachers, and doctors to satisfy future requirements.

摘要:

In a brief report inNaturefor April 12, 1953, K. B. Mather of the physics department of the University of Ceylon describes an expedition to the Garhwal Himalayas carried out in 1951 to investigate cosmic radiation with nuclear emulsions. The plates were exposed at an altitude of 18,400 feet at the Mana Pass on the border of India and Tibet, although the party reached an altitude of 19,150 feet in the course of the expedition. Mather points out that a number of reasonably accessible sites where high‐altitude stations of a temporary nature could be established at altitudes up to 20,000 feet exist in the Himalayas near the Tibetan border, and that electronic equipment as well as emulsions can be used at such stations if funds for porters are available.

摘要:

A new semiconducting material,a compound of aluminum and antimony, has been developed at the Battelle Memorial Institute in Columbus, Ohio. This potential competitor of germanium and silicon has already been used to make rectifiers with good high‐temperature characteristics, and possibly may also be used in making transistors. The cost of both aluminum and antimony is less than fifty cents per pound, compared with almost $350 per pound for germanium, and, although raw material cost is only a part of the expense involved in manufacturing a transistor or rectifier, the tremendous price difference makes the aluminum‐antimony compound a promising material for further study.
