摘要:

We may well start in this first issue by telling how Physics Today came into existence.

摘要:

We have progressed far enough since the war to be able to delineate trends in the pattern of science in this country, so that it becomes well worthwhile to take stock and examine whether on the whole it is a sound pattern that is being formed for the future. Much that is salutary is immediately apparent. The conspicuous swing that has occuried toward greater emphasis on the physical sciences was inevitable, in view of the startling effects produced by their application in the waging of war, and especially since the tension did not lift with the coming of formal peace. Yet the form which this emphasis took in this country is, in retrospect, a bit surprising.

摘要:

Events of importance to science have been happening in Washington since the war in almost unbroken series. In some cases, the struggle for mutual understanding among scientists and politicians, administrators and military personnel may have its less happy aspects, but because of the great power of science in national and international affairs at the present time, some of this is inevitable. On the whole, considerable understanding is being achieved.

摘要:

The international physics meeting in Holland in July 1948 may attract a considerable number of physicists, and in view of this it seems worthwhile to sketch the organization of research in physics in that country. Fundamental research is centered in the laboratories of the three state universities at Leyden, Utrecht, and Groningen, and in the municipal university at Amsterdam.

摘要:

Tracing the working of any one of the human senses from a physical stimulus to its perception by man brings into play taxing problems which reach to the limits of knowledge in each of the sciences it touches. Vision—color vision—is a particularly complicated process to study. Physicists investigate light, how it is emitted, absorbed, reflected, and how it passes through space. Physicists and biologists study how it passes through the eye; biochemists, histologists, electrophysiologists, neurologists, and so forth, study how it is received by the nerve‐sensitive retina and then passed on to the brain. Somewhere along the line the psychologist enters the fray.

摘要:

Resonance absorption is observed when a substance containing magnetic nuclei—protons, for example—is subjected to a strong constant magnetic field and to a weak radiofrequency magnetic field.

摘要:

I have seen physicists in their natural habitats, which are the universities; at their roundups, which are the regular meetings of the American Physical Society; on the prowl at Almagordo, Las Cruces, Bikini, Washington, Brazil; at a good many way stations; and (once) in jail. I have seen them talking—on the whole very sensibly—on physics; a little less sensibly on more remote matters; and very foolishly about newspapers.

摘要:

The connection between physics and cancer is peculiarly intimate—as intimate as cause and effect. For radiation, a valuable agent in the treatment of cancer, can itself cause cancer. This curious interrelationship exists largely because no one knows what causes growth, whether it be normal or abnormal. The primary problem in cancer is not an exploration of such isolated problems as the connection between radiation and cancer. It is the much larger and much more stimulating problem of understanding the fundamentals of growth.

摘要:

University of Texas physicists, under the direction of Dr. S. Leroy Brown, have constructed a mechanical harmonic synthesizer‐analyzer for solving certain types of mathematical equations.
