...balance tests, and exercise with a thick rubber band. But on the first orbit Carpenter began maneuvering the capsule by the "fly-by-wire" system, a semiautomatic device something like power steering on an automobile. As a result, he fell behind in his experiments, and began using up precious hydrogen peroxide, the fuel that is ejected as a gas to turn the capsule in flight. Says one Mercury official: "These guys all want to wobble the stick, and that's where the damn fuel goes." Balloon Bust. Little things kept going wrong. Passing over Nigeria, the temperature in Carpenter...
...clever instrument that can tell the difference was the hit of an erudite conference that met at Venice to discuss new methods of archaeology. Called a proton magnetometer, the gadget is based on a principle of nuclear physics discovered only a few years ago. The nuclei of hydrogen atoms (protons) are, in effect, tiny magnets, and they line up like compass needles parallel to the earth's magnetic field. When nudged out of alignment, they oscillate for a few seconds, the speed of their oscillation changing with the local strength of the earth's magnetism. Buried objects that...
Bottle & Coil. The magnetometer displayed at Venice was developed by Oxford's Research Laboratory for Archaeology, following U.S.-designed electronic circuits. The working arm of the instrument is a small (about 5 oz.) bottle of plain water, which contains hydrogen and, therefore, protons. Surrounding the bottle is an electrical coil connected to a control box. The magnetometer is usually operated by two people, one of whom moves the bottle from point to point, while the other sits at the control box. To make an observation, the controller presses a button, shooting an electric current from a storage battery through...
...height of what will reportedly be the first shot is so great that, for the first time, the residents of a large city, Honolulu, will be able to see the fireball of a hydrogen bomb at the instant of explosion. In 1958, a shot fired forty-eight miles above Johnston Island produced a flash visible in Hawaii, but the point of detonation could not be seen...
...career (Stanford, Princeton, Rochester, Pennsylvania and Carnegie Tech as well as Illinois), Seitz has been an outspoken champion of scientists who devote their talents to national problems. In the midst of the loud soul-searching that followed President Truman's 1950 announcement that the U.S. would develop a hydrogen bomb, Seitz stood before the American Physical Society and laid it on the line for his anti-H-bomb colleagues. Said he: "Who among us will feel sinless if he has remained passively by while Western cul ture was being overwhelmed?" In his new job at the academy, Seitz plans...
