...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 on a graph and reduce complicated wind motions to a series of simple, understandable oscillations. Thus mathematicians hope to predict how the shape...
...pastime of bouncing a rubber ball off the face of a wooden paddle. But those who have ever spent a night in Miami or Havana know that "high lie" is the way you pronounce the Cuban national game, spelled jai alai and played by scooping the ball in mid-air with shallow wicker baskets and hurling it against the walls of a long concrete court...
...boundaries of a fair serve (between the fault and pass line)-see diagram. Three walls are of concrete, the fourth is of wire netting to protect the spectators from a ball that travels 100 miles an hour. Object of the game is to scoop the ball (either in the air or on first bounce) as it bounds off the front wall, and, in a split second, return it so that it will be in a difficult position for the opposing player (or players) to catch. Points are scored in the same manner as tennis or handball. Winning score varies from...
...points were allowed for time, 25 for tone, 50 for execution (the technique of trills and capers with which every good piper decks out the tune he is playing). If a piper missed a melodic trick, or if he allowed his reed to "choke" (stop vibrating for lack of air), he was docked a point or two by the judges. Last week's winners: stocky James Bremner of Kearny, Pipe-Major John MacKenzie of Brooklyn, Piper Ed mund Tucker of Manhattan...
...they did in 1937, possibly larger. Last year, radio as a whole helped itself to about 17? of the U. S. advertising dollar,* running even with magazines, second to newspapers, which got 59?. Of radio's 17?, network-time sales took about 7?. The remainder went for air time sold by individual stations...
