...ended, they often find their way-as waste-into the air people breathe, the water they drink and the food they eat. Often invisible and immune to bacteriological attack, they damage plants, kill fish, slip undetected through sewage-treatment plants, and blanket entire cities with clouds of noxious vapor. Some, like sulphur dioxide, are clearly toxic-memorably so in the five-day siege of sulphurous smog in Donora, Pa. (pop. 13,000), which struck down 5,910 and killed 18 in October 1948. Others, doctors think, may have serious cumulative effects on human health-which will not show...
...earth's corona, Astrophysicist Shklovsky reasons, is mostly hydrogen which came originally from the earth's oceans. Water vapor works its way up from the lower atmosphere. When it reaches about 60 miles, its molecules are broken into oxygen and hydrogen by solar radiation. The hydrogen, being lighter, tends to rise, and above about 1,000 miles it becomes the main constituent of the atmosphere. Some of its molecules get hot enough and move fast enough to reach escape velocity and leave the earth entirely. Moscow's Professor Shklovsky believes that enough hydrogen has escaped in this...
...carefully, he first froze its joints into position with liquid nitrogen, then popped the bird into his kitchen freezer. When the moisture in the bird's body had turned to ice, Meryman used a vacuum pump and a chemical desiccant to remove the water in the form of vapor from the frozen body.

Twelve minutes have passed. At any point up to two minutes before the launching, the U.S.A.F. officer may turn his key, thus starting the activation of the warhead. But the warhead does not become fully armed until after the missile has been launched...
