Super-cooled water is water which has been chilled to a temperature below zero degrees Centigrade, without being allowed to freeze. When the chilling process stops, the water quickly freezes into small crystals resembling snowflakes...
...order to stimulate interest in science among the nation's youth, Dr. J. Allen Hynek, Associate Director of the Smithsonian Astrophysical Institute, has suggested scientific fairy tales to accompany "Mother Goose" stories. Bed-time lessons "on the origin of the numeral zero" should be inculcated in children in order to give them "a basic interest in science from an early age," preferably before they enter kindergarten...
...Year glaciological program for the Northern Hemisphere, leader of a four-man scientific expedition encamped (at 8,000 ft.) since April on McCall Glacier in Alaska's Brooks Range; apparently by his own hand (stripped to the waist, he walked some 200 yd. from camp, lay down in zero weather, froze in time-honored Eskimo-suicide fashion...
PROGESTERONE (the natural form) and the synthetic progestagens are female hormones. Given to men, they can both increase fertility and serve as temporary desexing agents, said Dr. Carl G. Heller after studies at Oregon State Penitentiary. In men with a low sperm count, the drugs drop the count to zero, but when the drugs are stopped, there is a rebound to more normal levels, increasing the likelihood of conception. In normal-count men, the drugs also reduce sexual desire, suggesting that they might be used along with psychotherapy in treating homosexuals...
...more astonishing is the evidence of a scientific society that produced a calendar (circa 353 B.C.), based on astronomical observations, which is considered more accurate than the Julian calendar that was devised in 46 B.C. The Mayans reckoned time from a zero date beginning, according to one scientist, with Oct. 15, 3375 B.C. Their month (urinal) lasted 20 days; a year (tun) 18 months, or 360 days,' which was completed (to correspond more accurately to the solar year) by adding five so-called "unlucky days." Thus they had a fixed calendar year of 365 days. It was nearly...
