...Cornell researchers, a young Israeli chemist named Akiba Bar-Nun and his biochemist wife Nurit, tested the theory in a relatively simple experiment. They filled one end of a brass-and-Pyrex tube with a mixture of ammonia, methane, ethane and water vapor-all probable ingredients of the earth's early atmosphere. A thin plastic membrane separated the gases from the other end of the tube, which contained chemically inert helium. The Bar-Nuns increased the helium pressure until the membrane broke. This produced a shock wave that swept into the gaseous mixture at high speed, momentarily creating temperatures...

...module's two spherical oxygen tanks was completely empty; nearly 320 Ibs. of supercold ( -297° F.) oxygen, a highly pressured mix of gas and liquid, had gushed out of the spacecraft, apparently through a rupture in its thin alloy skin. Looking out of his window, Lovell could see vapor streaming by. "We are venting something into space," he reported. "It's a gas of some sort." At the same time, the spacecraft began to pitch and roll in reaction to the violent expulsion...
...allot $600 to help the state root out a blight called pine blister rust went down because, as one man said: "We can do it better, and for nothing." One item on the "warrant," or agenda, suggested replacing Mount Vernon's 22 conventional street lights with 17 mercury-vapor lights to provide better illumination. When the first selectman explained that the change would increase the monthly electric bill by $25.90, a resident shouted: "Forget it!" It was unanimously voted down...
Golden Tube. The target of the chromatographic detective work performed by the bomb sniffer is the vapor from a chemical called ethylene glycol dinitrate (EGDN), one of the principal components of emissions given off by dynamite. With the aid of a small internal fan, the detector samples air in the vicinity of a suspect object and passes the vapors over a modern equivalent of Tsvett's limestone-a rough gold-plated copper surface that has a special affinity for EGDN. As the molecules adhere to it, their concentration increases. The special surface is then heated...
