...home, power-plant and factory combustion of coal and oil containing large percentages of sulphur. More than a tenth of air pollution consists of hydrocarbons, most of them emanating as unburned or only partially burned gaseous compounds from automobile fuel systems. Combustion also produces large quantities of carbon dioxide, nitrogen oxides and other gases...
...these products of combustion were not unpleasant or dangerous enough by themselves, some also undergo complicated chemical changes in the atmosphere that make them even less attractive. In the presence of sunlight, the hydrocarbons and nitrogen oxides emitted largely by automobile exhausts react to produce the sort of brownish and irritating photochemical smog that blankets Los Angeles for most of the year. "Los Angeles smog" is a highly complex soup containing, among other things, nitrogen dioxide, hydrocarbons, ozone (a highly active and poisonous form of oxygen) and peroxyacyl nitrate (commonly called PAN). "London smog," on the other hand, usually contains...
Simulated Solar Wind. To test his theory, Sun borrowed samples of meteorites believed to be similar to those on the moon. Using liquid nitrogen, he cooled them to-320°F. and bombarded them with high-energy electrons that simulated the impact of solar-wind protons for a 14-day period. No glow was produced. When Sun removed the liquid nitrogen and rapidly heated the samples, however, they began to give off vivid and pulsating light. The Westinghouse physicist is now working on further laboratory tests to support his theory. He believes that it can also be confirmed by careful...
Interest in the frozen way to immortality has led to the establishment of firms in Phoenix and New York that design and build equipment to contain bodies preserved by liquid nitrogen. These capsules cost more than $4,000 and require another $150 a year in maintenance. One woman who agreed to have her remains frozen explained: "With bad luck, I'll stay simply dead. With good luck, I may live again. It's worth trying...
