...return to the wrinkle theory of mountain building-but with a difference. The earth was cool and solid when it was formed, says Lyttleton; then radioactivity gradually heated its rocky material. A few billion years ago, the earth's central core got hot enough to change from a plastic solid to a true liquid. Under the enormous pressure that exists near the center of the earth, liquid rock is more compressible than solid rock. So when the core liquefied, it was squeezed into a smaller amount of space, allowing the layers about it to settle down...
Most of the earth's material is plastic enough to contract evenly, but the thin surface crust is rigid. Instead of contracting smoothly when the core shrank, it cracked and wrinkled, just as in the old theory. Sometimes parts of the earth's crust slid over other parts like sheets of ice in a fast-flowing river. These surface irregularities, much changed by erosion, are the earth's mountains...
...here that I decided that serenity could be an important contribution to our environ ment, because our cities are so chaotic and full of turmoil." Work on the consulate general - a white structure raised slightly off the ground like a Japanese temple and surrounded by bronze and plastic sun screens- drew him to Japan again, and Yamasaki decided to go the long way and take a look at some of the rest of the world. The great formative experience was comparing the Taj Mahal and Chandigarh, but he also learned a significant lesson from Europe's great Gothic cathedrals...
...claimed that the interlopers planned to set up a "guerrilla corridor" in Kwangtung "to open the way for a subsequent military adventure of invading the mainland." To back up the story, Communist newspapers splashed front-page pictures of the captured agents and their stockpiles of U.S. rifles, grenades, and plastic demolition equipment...
...heart murmur, then gradually failing strength until an operation seemed unavoidable. But to the surgeons who opened her chest two years ago, her aortic narrowing seemed inoperable. Last summer Patricia went to Dr. Arthur E. Prevedel, 44, who put her into Children's Hospital in Denver. He worked plastic tubes through arm veins into both sides of her heart, injected a radiopaque dye and took X rays to get a clear picture of her narrowed aorta. Her operation differed only in technical details from Ro Anne's. Dr. Prevedel sewed in a similar Teflon patch, and Patricia went...
