...fall on the basis of such evidence. But because it is presented more as a loosely buttressed personal obsession, it is not obliged either to stand or fall. Instead, the book's thesis simply sways provocatively to the ritual accompaniment of Harrington's prose-a flexible alloy of Mao-revolutionary and Norman Vincent Peale-inspirational...
...three-run spree in the third. Pete Bernhard walked to lead off the inning and advanced on a wild pitch by losing pitcher John Heyel and an infield out by DeMichele. With two down, Varney hit a grounder to third that went between the legs of the Lions' Jim Alloy...
...blessed with serendipity, the gift of finding something valuable without actually looking for it. Assigned by the Naval Ordnance Laboratory in Maryland to find a nonmagnetic and noncorroding material for tools that could be safely used in dismantling magnetic mines, he finally hit upon 55-Nitinol, a nickel-titanium alloy. During further experiments, however, he discovered that the alloy also had a strange and mysterious quality in the realm of science fiction: It had a "memory...
During laboratory tests, Buehler and Physicist Frederick Wang reported in Ocean Engineering, they fashioned Nitinol into a complex shape at a high temperature, then cooled it and crushed it beyond recognition. When they heated the alloy again, it magically regained its original shape, "remembering" every curve and angle...
...explanation, the scientists say, is that the Nitinol alloy was heated and shaped above its "transitional" temperature range - the temperature at which there is an atomic shift, or a change in its crystalline structure - then allowed to cool. No matter how they then distorted the alloy when it was below its transitional temperature, the atoms dutifully shifted right back to their original positions as soon as the alloy was heated above that temperature again...
