...that reach the earth's surface (most are burned up by the atmosphere), they estimate that meteors have deposited 450 billion tons of iron, 30 billion tons of nickel, 10 billion tons of phosphorous, 9 billion tons of carbon, 6 billion tons of copper and 3 billion tons of cobalt on or near the lunar surface. If their figures are correct, the meteor fall would also have contributed 300 billion tons of carbonaceous chondrites, containing about 30 billion tons of water chemically locked in crystals with other compounds...
...transitional temperature of these structures and of all Nitinol alloys can be "set" anywhere from - 320°F. to 330°F., Buehler explains, either by varying the percentages of nickel and titanium or by substituting cobalt for some or all of the nickel. Instead of going to the trouble of assembling structures under the sea, for example, Buehler suggests prefabricating them out of Nitinol set below seawater temperatures, cooling and compressing them and then airdropping them-still cooled -into the water. Raised above their transitional temperature by the water, they would unfold and remain rigid on the ocean bottom...
Popping Fuses. The ground rules called for the two cars, heading in opposite directions, to follow the same route, which would have a total of 53 stations where their batteries could be recharged. The floor of Caltech's minibus was covered with 20 lead-cobalt batteries, on top of which were pads where off-duty drivers slept. M.I.T.'s team borrowed a set of $20,000 nickel-cadmium batteries. Characteristically, the engineers used linear equations to work out a handicap system...
...improvements and prospects of further gains, said Dr. Myron P. Nobler, result from the use of modern radiation at supervoltage levels. This may come from a linear accelerator, a large cobalt-60 source, or a generator that puts out 2,000,000 electron volts. To protect the patient from radiation sickness and to spare normal tissue, healthy parts of his body must be shielded. At Memorial Hospital, said Dr. Nobler, an X ray with a grid background is made of the body area involved. On this X ray the radiologists mark the vital organs, such as lungs, which must...
...eggs, his favorite dish. He took his first hesitant steps, a few yards from his bed to an armchair on a sunny balcony, badgered his wife to bring the family for a visit, and nicknamed the daily blood sampler "Old Dracula." Every other day he got a dose of cobalt-60 radiation that his doctors had or dered in hopes of controlling the expected-indeed, inevitable-attempt by his system to reject the "foreign" heart muscle in his chest. Even so, he was doing so famously in the early part of the week that he hoped to go home...
