...brood of planets must be an exceedingly rare thing in the sky; the solar system may be unique among the billions of stars which constitute the Milky Way galaxy. To Sir James it is a simple matter of mathematical probability. He has done much to propagate the "tidal theory" of the solar system's origin which is probably more widely accepted among astronomers than any other. In this view, some 2,000,000,000 years ago, a wandering star happened to swing close to the sun, from which by its gravitational pull it drew out a long filament...
...twelve other men were working up underneath the completed centre span of the new San Francisco-Marin County bridge.* Like wrinkled grey granite, 220 ft. below them ran the swift tidal currents of the Golden Gate. Most of the men were standing on a heavy wooden platform, slung below the rail-girders on steel beams. They were yanking away the boards from beneath the hardened concrete floor of the 4,200-ft. span. Two men were below them picking fallen boards out of the stout hempen safety net that stretched the whole length of the span...
Krakatau, a volcanic island in the Sunda Straits about 25 miles from Java, destroyed two-thirds of itself in a mighty explosion in 1883, sent out a tidal wave that drowned 36,000 inhabitants of adjacent lands. In the Krakatau group, four new islands were formed from the wreck of the former three. Naturalists agreed almost unanimously that every particle of life, down to the last seed and spore, must have been wiped out by lava, ash, gas and steam, that if life again took root on the islands it must come from outside. A minutely detailed story of vegetable...
Last week a tidal wave of propaganda against venereal disease, having gathered force for 13 months, flooded the entire nation. In San Francisco and Manhattan, in New Orleans and Duluth, and in 200 communities lying between, groups of earnest men and women who support the American Social Hygiene Association listened to facts and exhortations. From the President of the U. S. and his wife down to the most blushing volunteer social worker, there was evidenced a determination to make venereal diseases, especially syphilis, as rare as typhoid fever. Repeatedly quoted.was President Roosevelt's recent dictum, first of its kind...
History of Propaganda. The tidal wave of propaganda against venereal diseases began on the Atlantic Coast, in the offices of Surgeon General Parran in Washington and Social Hygienist Snow in Manhattan. But in a sense the wave may be considered a tremendous backwash from California. At Palo Alto and San Francisco in the late 1890s, stubby little William Freeman Snow and tall, lanky Ray Lyman Wilbur were undergraduates (with Herbert Hoover), medical students, later professors together. Dr. Wilbur became (1911) Dean of Stanford University's medical school. Dr. Snow went East, organized and became (1914) general director...
