Atom-smashing machines-once the mysterious toys of theoretical physicists-have recently been put to everyday metallurgical chores: > In assaying ores, Geologists at M.I.T. have announced that when a sample of rock is bombarded with neutrons (heavy nuclear particles) from the cyclotron, some elements in the ore become radioactive and give off particles which can be detected either 1) on a photographic film in contact with the ore, or 2) with a Geiger counter, an instrument which clicks or marks a tape as each particle shoots through it. Since each element has a unique rate of radioactive decay (e.g., radioactivity...
Kenneth Henderson '26, of the American Alpine Club, showed movies of rock climbs in the While Mountains. These pictures included scenes of several climbs that the Club has recently made or is going to undertake for the first time in several years. The new climbs were made possible by the unusually large number of leaders in the Club this year...

Until its 12 in. guns are silenced, until the troops are bombed out of galleries bored through solid rock in the rearing head of the tadpole, the Jap can never hope to sail his ships into Manila Bay. For south of Corregidor it is only seven miles to the other shore of the harbor's mouth...
This is too huge a labor pool to transfer easily to other mining, but South African economists have themselves raised the question of using U.S. equipment for more useful purposes than gold, and have complained that their gold labor is being wastefully used. Rock-bound old General Smuts is having trouble enough keeping his Union together in the face of political opposition, race problems and fifth columning. Though South Africa may have to limp along with no new equipment, a likelier spot for a real labor shift is Rhodesia, with some 75,000 gold miners. Rhodesia's copper production...
Patrick Scanlon, William Cahill and Peter Roddy, tenders of Tuskar Light, last week saw a shiny, globular object float into the area swept by the light's beam. It was a mine. Slowly the waves carried it toward the rock. The three marooned men banked on the chance that tides might carry the mine to one side, but each wave closed the gap, a few inches at a time...
