Science: Sun Gun

*U.S. Diplomat Herbert Agar, an ex-newsman and a greater expert on propaganda than on science, said in London last week: "If the war had gone on another six months ... it was probable that someone would have learned to break the atom without controlling it. ... There was a danger that the Germans would have learned . . . first. . . ."

†The British last week revealed a fantastic antiaircraft weapon of their own: aerial minefields. Laid by old bombers just before an air attack, the air mines were suspended from balloons and small parachutes by piano wire; when a plane hit the lower part of the wire, the delicately attached mine would slide down and hit the plane. The British claimed that air mines downed at least a half-dozen German planes over London during the blitz. Once a small boy found a wire lying on the ground, yanked it, blew up a house six blocks away.
