...designed to be damaged electrically by meteorites at least 10 microns (1/2500 in.) in diameter, showed no more than one hit (possibly none) in 32 days. The satellite was not damaged, and Manring and Dubin conclude that only long exposure to this concentration of micrometeorites would do it any harm...
...poured some vodka into the goldfish bowl this afternoon--doesn't seem to be doing them any harm...
...Safe is a cold-war projection of an engineering principle used for decades in aircraft design and around dangerous machinery. The principle: if a device can fail, it must be assumed that it will fail, and it must be designed so that its failure will do minimal or no harm. Fail Safe on U.S. railroads, for example, means "the dead man's throttle." If an engineer dies at the controls, his pressure on a foot pedal or hand lever is released, and the train automatically goes into an emergency stop. Fail Safe at SAC means that SAC bomber crews...
...thought of building his new pleasure dome anywhere but in Brooklyn. He would be satisfied, he said, with the land around the Long Island Rail Road station at the west end of Brooklyn. That ancient terminal, he figured, would soon have to be rebuilt anyway; it would do no harm to tear down the adjacent slums, and the nearby Fort Greene meat market was long overdue for relocation. All O'Malley asked was land, condemned and handed over to him cheap. So in March of 1955 Democrat O'Malley rounded up his own political pals, buttered...
...behaves too much like calcium. The human body must have calcium, especially for its bones, but it makes little distinction between calcium and strontium. So when there is strontium around, it picks that up too-and deposits it in the bones where the radioactive forms can do the most harm.* When doctors try to flush strontium out of the system, the body is similarly undiscriminating: it is likely to get rid of too much calcium at the same time...
