...freshman game. St. John's forward Bill Schaeffer, whose 30 points led all scorers, hit a short jumper underneath with three seconds left in the game to tip the Yardlings...
...surprisingly, one of the few jubilant scientists in Houston last week was Geochemist Oliver Schaeffer, who led the team that calculated the age of the lunar material. He used potassium-argon dating, a method based on the rate at which radioactive potassium decays into argon (it takes 1.3 billion years for half the potassium to decay); as time passes, the ratio between the potassium and argon in a specimen changes at a known rate, thus revealing the approximate age of the sample. If there is any error at all, Schaeffer explains, he has underestimated the age of the rocks, because...
...addition to the argon that resulted from potassium decay, Schaeffer found an abundance of solar argon-and of helium and neon-that has collected during eons of bombardment by the sun. These particles were lodged only in the surface of the rocks, where they had remained undisturbed for hundreds of millions of years-more evidence that the moon's exterior has not undergone any recent upheavals...
...Gases. About one thing, U.S. space scientists have no complaint: Apollo 11 provided them with a wealth of data and lunar material. Last week, as they completed no fewer than 152 preliminary tests on 55 lbs. of lunar rocks and dust, they made several more interesting discoveries. Geochemist Oliver Schaeffer, seeking to determine what gases are expelled from the sun as solar wind, heated a pinch of moon dust to 3,000° F. Analyzing the escaping gases, he found that the lunar surface had absorbed considerable helium and hydrogen from the sun. But he also noted surprisingly large amounts...
