Electronic devices for seeing in very dim light have become commonplace, but all of them are blind in total darkness. Last week Baird Associates. Inc. of Cambridge, Mass, showed a recently declassified "camera" that needs no light at all, only infra-red (heat) radiation from faintly warm objects...
When the heat-ray image forms on the plastic, the "bright" parts of it are warmer than the dim parts. Their heat passes through the plastic and evaporates part of the oil film, making it locally thinner. When light is turned on the oil film, it glows in the bright "interference" colors of an oil slick floating on water. The colors have nothing to do with the real colors in visible light of the object that Eva is viewing. They show thin or thick parts of the oil film-and therefore outline the object by its temperature. Hot parts show...
...Boys' dinner, Widmerpool, as the man of the '30s, horrifies all by making a long, uninvited speech on economics. The old housemaster, a neurotic, twisted pillar of the Old Order, salutes the onset of economics by suffering a stroke, and the Old Boys disband to their dim and several destinies...
...issue: interpretation of the so-called "non-Biblical writings" found with Old Testament scripts among the Dead Sea Scrolls. The verbal storm created by scholars has unleashed some fancy copy in the press; more important, it has stirred public interest in material that previously was confined to the dim offices of archeologists and theologians...
Mars Problem. Most romantic use of "light amplification" is in astronomy. The biggest telescopes do not magnify more than much smaller ones do; their purpose is to gather more light, making dim stars and nebulae bright enough to affect a photographic plate. Much the same result can be accomplished by amplifying dim light instead of gathering more of it. Dr. Albert G. Wilson, director of Lowell Observatory, Flagstaff, Ariz., believes that a 40-in. telescope equipped with a Lumicon will equal a 240-in. telescope in luminescence. The 200-in. Hale telescope on Palomar Mountain, the world's biggest...
