...earth's magnetic field. But near the poles, where the lines of the field bend toward the earth, the protons slam into molecules in the upper atmosphere and cause a shower of electrons. These, in turn, crash into nitrogen molecules, ionizing them and allowing them to combine with oxygen. As a result, nitric oxide (NO) and nitrogen dioxide (NO 2 ) are formed; both react readily with ozone molecules and cause their destruction...
...Brandeis quintet had gone into its swan song and had yet to emerge from the profound torpor. In a singular exhibition of botched marksmanship, the Judges repeatedly rent the oxygen with reckless abandon from any and all points on the floor, as their shooting percentage rivalled the life expenctancy of starved fruit flies...
...snow and weakened several large rock outcroppings; they warned that as much as 40 million cu. yds. of rock, a mass three times greater than that of Grand Coulee Dam, could break loose, slide into the lake and trigger flooding. In September, researchers from Eastern Washington State College, wearing oxygen masks to protect them from the sulfurous fumes, made their way through cave passages in a 140-ft.-thick layer of ice and snow to reach the center of the crater. There they found a football-field-sized lake of steaming acid, some of which is leaking into streams...
...everyone learns sooner or later, home means both heart and hurt. In the home of the Wingfields, modeled on Williams' own, there is the memory of the absent father, the telephone-company man who "fell in love with long distance." The suffocating mother, Amanda, uses up all the oxygen in any room she enters. The crippled sister, Laura, is as fragile as her tiny glass animals, and the task of the artist-to-be, Tom, is to break out of this enmeshing spider web if he is to salvage his own soul...
Lester himself made it to about 21,500 feet. He said that if he had insisted, he might have been given a chance to go to the top of the world, but he would have made some enemies since oxygen and supplies were rare...
