Although these bell-like reverberations were unlike any seismic event on earth, Columbia University Geophysicist Gary Latham offered a plausible explanation. The effect may have been caused, he said, by a layer of rubble or fractured rock sandwiched between bedrock in the floor of the Ocean of Storms and a solid cover of fine material deposits above. Lacking dampening fluids or gases, the layer of rubble may have acted as an echo chamber in which the seismic waves reverberated. If so, the next big seismic event on the moon should be a scientific spectacular; the third-stage rocket of Apollo...
...around, too, because this stretch of the creek was the spawning area. I watched one perch for two weeks while it faithfully guarded its nest against the other fish. It was there every morning and every evening; then one day it was gone. All that was left was a layer of silt from a construction project that the university had just started a little further up the creek...
...dating each ice layer like growth rings on a tree, the scientists have been able to use the oxygen-isotope ratio to chart yearly variations in weather to depths of 300 ft. Beyond that level, the annual record becomes blurred. But it is still clear enough to let scientists distinguish broad climatological trends. Analysis of the layers showed, for example, that the earth's last ice age began some 70,000 years ago and did not end until about 10,000 years ago. The investigators also made some long-range forecasts. Projecting the established weather pattern, they predicted that...
...Faculty who support the last proposal. suggestions that the administrative load of the Dean of the Faculty might be substantially lightened by the appointment of area Deans have come to us with much greater frequency. But fears have also been expressed that the creation of an additional layer of deans would delay and impede rather than facilitate decision-making. Our own disposition is to believe that decisions on the organization of the Dean's office ought best be left to the Dean who presides over it. Individual Deans will vary widely in their administrative styles and working habits...
...Mariner data, Pimental reported that his ephemeral clue to the existence of Martian life had proved to be false. What he had read as the characteristic "signatures" of methane and ammonia in spectrographic information gathered near the Martian south pole, he admitted, were actually produced by a thick layer of frozen carbon dioxide, otherwise called diy ice. How did the embarrassing error occur? Only when he checked out the experiment in his laboratory, Pimental explained, did he learn that a thick layer of dry ice could produce spectral characteristics similar to those of methane and ammonia...
