...with Polaroid for the amateur snapshot market. But for some special applications, its lack of negatives or complicated chemical developers is a distinct asset. All that is necessary is to spray the film's photoconductive plastic top with an easily generated positive charge of static electricity. The bottom layer of the film carries an equal, but opposite, negative charge. Those two electric charges, although powerfully attracted to each other, are kept apart by the thin plastic film...
With the help of the sea nymph Calypso, far-wandering Odysseus prepared to sail for home across the wine-dark sea. But when he had finished his boat, why did he cover the bilge with a layer of brushwood? Generations of scholars have sweated over the passage without producing a satisfactory answer. One theory holds that brush is only a mistranslation of ballast; some classicists argue that Odysseus was merely making a bed. A few despairing translators have ignored the brush entirely. Not until recently, when archaeologists learned to skindive. was the puzzling passage explained...
...Jack Benny almost never does. His material is gauged for longevity rather than flash. His patent for permanence is simply that he can do no wrong. His cheapskate, self-deceiving, inept, shrug-it-off, endearing and vainglorious public character has grown round him for decade after decade like layer after layer of cement, and he has long since become utterly indestructible. Many of his peer contemporaries-Eddie Cantor. Fred Allen, Ben Bernie-are either retired or dead; but Benny just keeps on standing there with that look, and warm, unraucous laughter ripples all over the room...
...romance of science and turn out to be teeming with life? Were there, as some romanticists confidently expected, forests of intelligent, moving trees? Or would Mariner prove the accuracy of some of the glummer theories of radio astronomy -that Venus is a barren ball covered with a dull layer of dust? Last week JPL's boss, New Zealand-born Physicist William Hayward Pickering, brought his Mariner team to Washington to deliver a batch of decoded data containing the first series of answers...
...same molecular machinery produces the other colors. When green light from foliage forms a latent image on the green-sensitive layer, the magenta dye, which is nearest that layer, is captured. The other dyes, yellow and cyan, are free to go to the surface and become the green leaves in the finished picture. Similarly, yellow and magenta make red. Intermediate colors form at places where the images overlap weakly, allowing fractional amounts of dye to escape. White light in the picture (such as a cottony summer cloud) makes exposed spots on all three layers, capturing all the dyes and leaving...
