摘要:

IT TOOK a technological war of world proportions to suggest that the problem of scientific and engineering manpower might profitably be studied, and the threat of another such war to initiate action. Inevitably, government agencies took the lead in analyzing those aspects of the problem that required immediate attention; but discontinuity of effort and uncertainty of purpose characterized official efforts and nullified any constructive or lasting result.

摘要:

Joseph Henry's genius was attracted primarily to the great experimental problems of his age. Although he was a professor of natural philosophy, a discipline which a century ago combined the various branches of physical science, he is not known to have indulged in the kind of formal considerations to which the title of this evening's discourse alludes. Yet I am confident that my subject is not wholly inappropriate to the occasion of a lecture in honor of Joseph Henry. For his eminent biographer, Charles Greeley Abbot, describes him as “a man of varied culture, of large breadth and liberality of views, of generous impulses and of great gentleness and courtesy of manner”. Hence, while the speculations on which I am about to embark can hardly aspire to honor his memory, we may take comfort in supposing that he would gracefully listen to them and accept them as a small token of respect.

摘要:

With the exception of the Hiroshima bomb and Darwin's voyage on theBeagle, few developments of science have had as great an impact upon the human imagination as Agassiz's announcement in 1837 that currently habitable portions of the earth had been covered in geologically recent times by ice sheets thousands of feet in thickness and covering millions of square miles. At first hotly contested, the postulate finally gained universal acceptance because of such indisputable evidence as typically glacial till, drift, and boulders transported hundreds of miles from their bed‐rock origins; deep abrasion markings on the surface of bed‐rock recording the grinding flow; moraines and hills of glacial deposits along with typical lakes, rivers, and so forth.
