...lava and "black smokers" heat up the depths of the oceans, a controversy over whose model correctly predicts the shape of the earth's crust and mantle is heating up geologists at Harvard and around the country...
According to Professor of Geology Adam M. Dziewonski, hotspots underneath mid-oceanic ridges in the earth's mantle can reach depths of 300 or even 600 kilometers. This suggests that mid-oceanic ridges are active suppliers of crust-forming material, rather than simply passive openings from which hot mass flows...
...analyzing tens of thousands of waves to determine their trajectories and velocities, the Harvard team extrapolated a model of hot and cool spots in the mantle. They were able to prove that hotspots underlying mid-oceanic ridges affect wave speed more than 100 kilometers below the crust, and therefore that the hotspots must extend to such depths, some up to 600 kilometers...
...football game. We stayed long enough to catch an overdose of Princetonian white picket fences and rabid Ivy League alums sporting fedoras, blue sportcoats with PRINCETON TIGER pins and drooling orange and black. If Atlantic City is one big dirty underbelly, then Princeton can safely be called the upper crust. Anyway, two versions of Americana over the space of two rainy New Jersey days. You can't beat that...
Actually, it might have been better to have presented The Importance of Being Earnest with an American flavor than to have created this harsh imitation of the upper crust English accent. It was one of the few flaws of this performance: this attempt to bridge the Atlantic gap was often wildly funny, but it was certainly not Wilde...
