Utilizing radiant energy from the sun is a dream that has harried many an experimenter. The sunshine falling in eight hours on a square mile in the tropics is equivalent to the energy stored in 7,400 tons of coal. The difficulty is to devise a sunshine catcher which is not expensive out of all proportion to the power produced. This is the defect of the commonest solar machines which have appeared so far-huge concave reflectors which focus on a boiler, make steam to drive small engines. One of the most optimistic U. S. experimenters, Dr. Charles Greeley Abbott...
...accommodate the concepts of modern quantum theory. Clothing electrical phenomena in mathematical language, Maxwell discovered electromagnetic waves by inventing them out of his own head. He then correlated electromagnetic waves and light waves. But his equations were based on the assumption that these waves could represent any amount of radiant energy, depending on conditions at the source...
Along came Max Planck to knock this assumption into a cocked hat with his discovery of bundles and jumps. In 1900 Planck announced that radiant energy could only be propagated in tiny, indivisible bundles which he called quanta. Furthermore these bundles did not proceed through space continuously, but by jumps. It was not long before experimenters were finding this lumpiness and jerkiness everywhere. Albert Einstein used it to explain photoelectric action. Subatomic explorers found that atoms had only a fixed number of orbits in which their electrons might travel; that the electrons jumped from one orbit to another with emission...
...cure and conquer all. One thing was certain. Spain's one-time Crown Prince Alfonso no longer looks tainted. From 92 Ib. his weight has climbed to 136-since the day twelve months ago when into the Swiss sanatorium where he was lying came a ripe-lipped, radiant Cuban patient, Senorita Edelmira Sampedro, daughter of a rich Cuban merchant...
...Arnold Scheifer's restaurant in New York, George Frei is the waiter in the alpaca jacket who serves the veal stew, the fried potatoes and the draught beer. He served them last week with a broad and radiant grin. For years he saved all his tips so that his boy need never learn to balance a tray or memorize an order. George Frei Jr. wanted to be an architect. George Sr. sent him to the Harlem Vocational School, then to art classes in Cooper Union, then, while he worked as a draughtsman, to New York University. Last week...
