...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 on a graph and reduce complicated wind motions to a series of simple, understandable oscillations. Thus mathematicians hope to predict how the shape of an airplane wing will affect the motion of the wind. Next practical step would be designing of a wing for more speed, safety, lift. Application of the "ergodic" theorem...

...graph has not been a smoothly rising curve. Objectors have fought it because they feared politics, threats to academic freedom. Aid reached less than half the boys and girls who asked for it. In 1937 the fund was severely cut (to $50,000,000). Finicky colleges like Harvard and Yale haughtily kept NYA out because its pay was skimpy. It was criticized for having such lay figures as Glenn Cunningham, William Green, Owen D. Young, the late Amelia Earhart on its advisory board...
...lecture three weeks ago on the need to balance prices, President Roosevelt singled out plaster as one article for which the price is too high. Leaning back in his chair with a long wooden pointer, he discussed a large graph showing that plaster prices are now twice what they were in 1929 (TIME...
