...cloud of its own making. This cloud is the out-spraying of the earth's spherical atmosphere which hugs the earth like a skin about 100 miles thick. Neutral atoms and molecules at the outer rim of the atmosphere dart further away from the earth into space. Sunlight ionizes them, creating an extremely tenuous cloud of ions and electrons. These radiate a faint light of their own, comparable to the light of the sun's corona. Zodiacal light and Gegenschein are the earth's coronal light visible from within. It is without any doubt too faint...
...light did not exert pressure this ion and electron cloud would be spherical in form. But because light does press, sunlight forces the cloud into its egglike shape. The butt side is towards the sun. It is in that direction 30,000 miles thick and appears as the Zodiacal light. From the opposite side of the earth where the cloud's resistance to sunlight pressure is less it is squeezed a million miles or more from earth into a thin taper. That is where the Gegenschein glows. Through that taper the earth's atmosphere very, very slowly escapes...
...humidly hot in Sumatra; the intense sunlight encourages luxuriant plant life. One of the chief Sumatran products is, as all the world knows, rubber. South American rubber is garnered mainly from wild trees, carried through jungle paths. In the Far East and Middle East the business is much more highly organized. To handle the product roads have been built, heavy trucks imported; railroad tracks have been laid. The only primitive factor remaining is the labor-cheap labor that can be bought for about 30? a day. Loinclothed natives do most of the work. They slit the rubber tree...
...incident of the Manhattan meeting of the American Institute of Electrical Engineers last week (see below) was Dr. Matthew Luckiesh's presentation of his new General Electric sunlight lamp. The bulb is 6¼ in. long. It contains two separated tungsten electrodes, a little pool of mercury, a tungsten filament. When the electric switch is turned, current heats the filament to incandescence. The heat vaporizes the mercury. The mercury vapor diffuses between the electrodes and permits the current to jump across as a brilliant mercury arc. The combined light of arc, electrodes and filament appears much whiter than Mazda...
...supplies. They learned that the sun-browned, crudely clad gentleman was no castaway, but a German scientist, Dr. Karl Ritter. He once lived in Berlin, has a wife in Baden. Last July, tired of civilization, anxious to study the effect of uncooked foods on the digestion and sunlight on the skin, he projected the Galapagos venture. First he visited a dentist who extracted all his fallible human teeth and substituted durable artificial ones. Then he set forth with a devoted female assist...
