Many people who are thinking about taking the first trip, that "easy one," don't know exactly what the trip involves. Lots of tourists, driving through Virginia of Kentucky, have stopped to visit a commercial cave. For a fee, a guide takes you in over surfaced paths that wind around electrically-lit rock formations. You could get the impression that caving is much like that, but without the lights, crowds, or the admission charge--just wandering in awe through the crystalline depths of the earth...
Lunar Bombardment. Writing in Nature, Physicist Kuan-Han Sun suggests that a combination of the solar wind, meteorites, and lunar temperature changes provide ideal conditions for thermoluminescence-the release of stored-up energy in the form of visible light during a rapid temperature rise. Like other bodies in the solar system, Sun points out, the moon is constantly bombarded by a solar wind consisting of charged, low-energy particles boiled off the solar surface and "blown" into space. Because these particles, which are mostly protons, follow magnetic lines of force, they can strike the moon from all directions, hitting...
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...
...distance runner has to love the wind running through his hair. He has to have a distance runner's mentality," Hardin says getting up from the couch. Whatever it is, and it seems to be an odd mixture of the serious and the esthetic, Doug...
