摘要:

The Reserve Forces Act of 1955 has been placed on the statutes and thus the military manpower program of the nation has been settled for a time—possibly a long time. It seems unlikely that the Congress will open up these touchy issues short of a gathering international storm. The present legislation could be with us a long time.

摘要:

For a number of reasons physics journals published in the Soviet Union have not enjoyed an especially wide circulation in the United States, but even if the mails suddenly were to be filled with Soviet physics periodicals there would still be the difficulty that scarcely one American physicist in a hundred can read enough Russian to make use of a scientific paper in that language. While it has been argued that so glaring a deficiency should and eventually must be remedied in the schooling of future physicists, the fact remains that physicists in this country have been unable to follow the published literature of Soviet research, even by means of translations. Although various agencies have undertaken the translation of selected physics papers from the USSR, there exists no complete and up‐to‐date set of English translations of the Soviet physics journals. At the same time there is abundant evidence that physicists in the USSR have a close familiarity with the non‐Soviet physics literature and are making swift and efficient use of Western research techniques and results.

摘要:

The usefulness of logarithms in the measurement of many of the stimuli to which human beings are sensitive is almost too obvious to need argument. Three reasons are commonly given to justify the practice:1. The intensity ranges of the physical stimuli are enormous—energy ranges of trillions to one are involved in vision and hearing.2. To a rough approximation, discrimination follows a law of relativity: the just detectable increment in a stimulus is proportional to the magnitude of the stimulus (Weber's law). Hence, to the extent that Weber's law holds, the logarithmic difference that is just detectable is constant.3. According to Fechner's law, the subjective magnitude of a sensation is supposed to be proportional to the logarithm of the magnitude of the stimulus.

摘要:

The history of education has been a series of stormy, volcanic eruptions which have periodically changed the character of American Education. Educators have been hampered because they have been without one consistent aim. Education has been a public enterprise and therefore at the mercy of certain pressure groups, individual opinions, and community whims. Educators have also been hampered because the great philosophers of education have interpreted the values of education individually and personally. Each has been an educational missionary who gathers a group of followers, deviates from other groups, and eventually becomes powerful enough to break through a small fissure in the side of the volcano of education and start another little volcano.
