...Harvard in 1900, became a professor in 1918 after winning the Cross of the Legion of Honor in France. Now head of the department of Mathematics and periodical (average every five years) author, he is one of the best known, mathematicians in the world. After writing on the Complex Domain (1924), he does not find it hard to count his eight children...
...with the study of fluctuating or oscillating motions. Ever since the 18th Century mathematicians have occupied themselves with the hypothetical case of an infinite piece of string. In how many ways could such a string vibrate? Today the problem has taken a more practical turn. Mathematicians want to separate complex waves and oscillations into simpler movements. Chief use for harmonic analysis is study of the problems presented by the whirls and eddies of air around airplane wings. For example, harmonic analysis makes it possible to measure the varying speed at different points in a wind tunnel, to plot these speeds...
Economists have about the same fun drawing conclusions from the weekly reports of the Federal Reserve System as scientists do drawing new diagrams of the atom. On one series of the complex Federal Reserve statistics all commentators are agreed-that the rise and fall of commercial loans by U. S. banks is usually a good measure of business activity. Thus, all through Depression II the volume of credit issued to business has fallen (with occasional minor reversals) some $20,000,000 a week in New York City, another $20,000,000 in the rest of the U. S. Last week...
...never practiced law in St. Louis, and he became, in his own eyes at least, a failure. He also became the most puzzling and complex of American men of letters-a politician who was also an expert in medieval architecture, a novelist who wrote under a pseudonym and accused his friends of writing his books, a leading historian who announced flatly that histories were all lies, an amateur geologist, economist, photographer and naturalist, and an author whose two masterpieces were published despite his strenuous efforts to suppress them...
...washing dishes, judged Mr. Fuller's proposal that the house be set up by being dropped from a Zeppelin a little visionary. Although it excited less discussion, critics were more impressed by his model bathroom exhibited in Manhattan four months ago, supplanting the present complex arrangement of pipes and drains with a unified, economical design as symmetrical as a piece of metal sculpture...
