...project will cost in toto upwards of $170,000,000. Materials for the dam were not included in the builders' contract, will be bought separately by the Government. The Southern Pacific's railroad tracks and Western Union's wires must be expensively rerouted through a tunnel west of the dam. A long system of canals and transverse ditches will be dug, to carry water not only to Sacramento Valley farmers but far south into the San Joaquin Valley, whence waters have been diverted to thirsty Madera, Fresno, Tulare, Kings and Kern counties...
...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 of an airplane wing will affect the motion of the wind. Next practical step would be designing of a wing for more speed...
...their hands ever manage a steering wheel, many New York school children will know that acceleration, not braking, is the way to control skidding; that the best way to start on an icy surface is in high, not low gear. They will know the dangerous effect of automobile radios, "tunnel vision" (inability to see out of the corner of the eye), and thinking about quarrels with one's wife (perseveration). As pedestrians they will be taught to cross at crossings, hold umbrellas high, walk to the left on rural highways and at night to carry a light or something...
Last week Administrator Hopkins' staff was busy checking over new projects submitted by local administrators for addition to their "back-logs"-work to be done when current projects are finished-plans to occupy 1,000 men for six months building a sewer and tunnel at Michigan Avenue and St. Clair Street, Chicago; 21,200 man-hours working the roads of Greene County...
...twelve hours the fire raged, go feet below the river surface, 70 feet from shore, fought hopelessly by sand hogs with hand extinguishers, firemen who braved the terrific pressure to attack it with hoses. After a grim night of defeat, tunnel engineers resorted to extraordinary tactics. Slowly, pound by pound, they began reducing the air pressure in the fire-swept section. Just as slowly, the air wall gave way and the river it had been holding out began to muck in. In half an hour, it half-filled the section, doused the fire...
