...TIME'S EDITORIAL STAFF HEARTIEST CONGRATULATIONS ON BOTH THE VISION THAT PROMPTED AND THE COURAGE TO PRINT CHARLOT'S BEAUTIFUL NATIVITY SCENE [TIME DEC. 26]. MAY THE LIGHT OF THE WORLD HELP US TO DISPEL THE CLOUDS OF HATRED, THAT PEACE AND GOOD MAY REIGN ON EARTH...
Once East of the Panama Canal the Pacific Fleet will be joined by two new aircraft carriers, four battleships, seven light cruisers, seven destroyers of the newly formed Atlantic Squadron. A cardinal principle in Navy strategy has long been that "the Fleet" should largely remain together, ready to move as a unit and at maximum strength to any threatened point. Whether the Atlantic Squadron is to grow into a separate Fleet is a matter of dispute...
...psalms and hymns and spiritual songs." On any Sunday throughout the U. S., among the thousands of hymns which drone toward Heaven are sure to be the following well-beloved four: The Church's One Foundation; O, Jesus, I Have Promised; Onward, Christian Soldiers; Softly Now the Light of Day. Last week Rt. Rev. Benjamin Dunlap Dagwell, chub-cheeked Episcopal Bishop of Oregon, suggested that these old soldiers be given a rest. Said the Bishop, who has sung them since he was a chub-cheeked choirboy: "They are fine hymns and should be used from time to time...
Electron Microscopes now attract much attention among scientists who want to see ever smaller & smaller things. The magnification of ordinary microscopes is limited by the wave nature of light. Some things are so small that they slip through the meshes of the light rays like BB shot through a tennis net. Instead of a beam of light the electron microscope utilizes a beam of electrons, which have wave lengths thousands of times shorter than visible light but also make impressions on photographic plates...
Pure science gave way to practical technology when one of Dr. Langmuir's coworkers, Dr. Katharine Burr Blodgett, found that a layer of transparent liquid soap, with a thickness of one-quarter the average wavelength of white light (about 4/1,000,000 in.), made the glass to all intents and purposes invisible. Reason: glass is visible because of the light reflected from its surface; with a soap film there are two reflections, one from the glass and one from the soap; by spacing the two surfaces properly it is possible to get the "crest" of a light wave bouncing...
