From one danger, however, even the aqualung could not secure the divers--the drunken elation induced by nitrogen gas under the tremendous pressures of the depths. In the intoxication of the "zone of rapture", the diver may lose control, as one of the group did, and tear the aqualung from his back as an impulsive gift to a passing fish...
...rapture, which comes on at about 200 ft., is apparently caused by the oversaturation of the nervous system with nitrogen or carbon dioxide under the increased pressure. "The first stage," writes Cousteau, "is a mild anesthesia, after Which the diver becomes a god. If a passing fish seems to require air, the crazed diver may tear out his air pipe or mouth grip [and offer it to the fish] as a sublime gift...
Willy Knoblauch was a model worker at the hot carbide furnaces of the Piesteritz nitrogen plant in Communist East Germany. The comrade leaders of the plant union liked Willy. But Willy did not care much for them...
...severe operation; it may last five. But before the first week is out, the process normally begins to reverse itself, presumably because the hormone switches have been flicked. The patient than gets hungry. He needs fat and carbohydrates from food to provide calories. He starts to take up nitrogen and rebuild muscle protein at the same prodigious rate as a one-year-old (suggesting that the growth hormone may have been switched on). The need for sodium goes down, while that for potassium goes up. Weeks or months later, the body replaces its store...
Chemist Libby's water clock will be based on the same principle as the carbon 14 calendar. Some ten miles high, in the stratosphere, cosmic rays stream in from outer space. With far more force than an atom-smasher, the cosmic rays collide with nitrogen atoms. The crash produces hydrogen, carbon 14 and a minute amount of radioactive tritium. The atoms of cosmic tritium join molecules of water vapor and fall to the earth in snow and rain...
