Without leaving comfortable Cavendish Laboratory in Cambridge, England, Physicist J. F. Nye took a crack at a new kind of Arctic exploration. Using the integrations of abstruse equations, he ranged over Greenland's great icecap, checking the observations of scientists who had made the trip in person. In Nature magazine, Dr. Nye reports his findings. Greenland, he concludes, is probably a mountain range rising from the sea, surrounding a vast, frozen, inland lake...
...Light. The Army has dreamed of drafting the atom into the artillery ever since it heard about Hiroshima. But the dream was wild and impractical until the atomic scientists discovered how to bring off small, controlled, atomic explosions. Then a young Army ordnance expert who is also a nuclear physicist, Colonel Angelo R. del Campo, drew up some sketches and took them to the AEC laboratories at Los Alamos. Working in high secrecy, West Pointer del Campo spent months juggling the requirements of artillery against the requirements of an atomic charge. (Sample: the mechanical parts of an atomic bomb need...
Edward C. Pickering, professor of Astronomy, was the central figure after 1876. He entered with a new attack on astronomy, applying his background as a physicist to the construction of equipment capable of measuring the light of the various stars to determine their magnitudes. He began the photographic survey of the skies, and his work was so extensive that much of it has been used to solve fundamental problems of today...
...often important for doctors to know how much water there is in a patient's body, especially if he has heart disease. Almost 20 years ago, Physicist George Hevesy worked out a way to use the stable isotope of hydrogen (deuterium or hydrogen-2) in heavy water for this purpose. But the technique is complicated and takes a long time. Now the University of California's Dr. John H. Lawrence, one of the first and most imaginative of the atomic medicine men, can do the job far faster with heavy-heavy water, the oxide of hydrogen3 or tritium...
...first radio-iodine used had an atomic weight of 128, but Dr. Joseph G. Hamilton, pioneering with it at the University of California complained that it lost its radioactivity too fast' Physicist Glenn Seaborg nodded, said-"I'll see what I can find." He found iodine-131 -Which is also believed to be the vital element in the H-bomb.*Thanks to the accident of prior discovery, radium has never been brought under similar control. Anyone can buy as much as he can afford and carry it home in his pocket. It might cost...
