Show Hot and Cold Overhead Man's effort to learn more about this universe is interesting and nothing is more remarkable than the willingness of scientists :o abandon-erroneous beliefs once they are convinced that new tacts have been discovered. For years, balloon observations have led scientists to believe that the stratosphere is icy cold, but recent experiments by Dr. Fred L. Whipple, of Harvard University, Universi-ty, seem to indicate that this theory is altogehter wrong. Dr. Whipple says that his experiments ex-periments indicate that at an altitude alti-tude of twenty miles, the temperature tem-perature rises from about fifty-five fifty-five degrees below zero until at thirty-eight miles it reaches one hundred degrees centigrade, which is the boiling point of water. Still farther out in space, the scientist reports, the temperature drops again and at fifty miles is ninety degrees below zero. Then it increases again until at seventy miles and higher the temperature is about twenty degrees centigrade, centi-grade, which is ordinary room temperature. Just w-hat this information is worth at this time may be a matter of speculation, out you can take it for granted that scien- j tists will use it as a Dasis to ascertain as-certain new facts. Eventually, j when all facts are available, we might begin to understand some-! thing about the universe, of which the world is only a tiny j part. |
