...champion leaper-to-a-conclusion. Last year Dr. Ehrenhaft started a sharp argument among physicists by announcing that magnetism has currents which flow like electricity (TIME, May 22). At a Manhattan meeting of the American Physical Society last week, he told how he had projected a very fine light beam vertically in a glass tube, then dropped into the beam microscopic particles of matter (e.g., chromium). When the particles were smaller than the light's wave length, they fell straight down. But bigger particles, instead of falling straight, as they would have if affected only by gravity, fell...
...Sussex ploughman asked Dr. George K. A. Bell, Bishop of Chichester, to bless the plough, "the sign of all our labor in the countryside." The Bishop, wearing a gleaming cape of green and gold, raised his hand over the plough and the kneeling farmers: "God speed the plough: the beam and the mouldboard, the slade and the sidecap, the share and the coulters . . . in fair weather and foul, in success and disappointment, in rain and wind, or in frost and sunshine. God speed the plough...
Landing is accomplished by means of radio. In a normal instrument landing, a pilot aligns his plane on a radio signal beam from the field and steers his plane along it. In the new system, the radio signals themselves steer the ship; the pilot need not touch the controls. One instrument, the "localizer," guides the plane toward the middle of the runway; another, the "glide path," controls its descent. The instruments can pick up a plane 15 to 35 miles away at 3,000 feet altitude and glide it in to a perfect three-point landing...
...beam of light bends when it passes from water to air or vice versa; it also bends when it passes through air masses of varying density. Barnes and Bellinger caught these rapid changes in air density by means of an extremely fast mercury lamp with an exposure of less than one-millionth of a second. The light, flashed through a region of disturbed air, recorded on a photographic plate a "shadowgraph" showing groups of bunched air molecules. Using a more elaborate rig, which has a knife-edge that stops all but the bent light rays, the experimenters developed a technique...
Publisher Hillman and Editor Lyons bristle at the suggestion that their new 25? slick-paper, pocket-sized magazine is another Coronet, beam at comparison with Reader's Digest. Disinterested readers may find Pageant an agreeable blend...
