...population. After World War II, efforts at purification were set back further: detergents and other chemical effluents left the lower Thames covered with foam, literally choking the river to death. Deprived of oxygen, one fish species after another vanished. River passengers became ill from the rotten-egg aroma of hydrogen sulfide rising from the polluted waters...
...Rome still more was being said on the subject. Remarked Belgium's Cardinal Suenens: "People will ask, 'Is he John or is he Paul?' He will be both in his own way. His manner is more John's, but it is like mixing oxygen and hydrogen - you get water, two different elements producing a third substance...
...inward pull of the star's gravity. In a star like the sun, the battle between radiation and gravity is long stalemated; the sun has been shining for some 5 billion years and will remain relatively unchanged for another 5 billion. After the star exhausts most of the hydrogen near its core and begins to burn hydrogen in its outer regions, it swells into a red giant. When the sun reaches this stage, its hot gases will envelop Mercury, Venus and the earth...
...milliseconds, the doughnut-shaped device known as the Princeton Large Torus held a plasma of hydrogen and deuterium in a strong magnetic field at a temperature of 60 million degrees centigrade-four times higher than the sun's own internal heat and better than twice the mark set at Princeton last December. Equally important, feared instabilities at that temperature did not occur, making the physicists more confident than ever that they will be able to demonstrate the scientific feasibility of fusion by reaching the magical break-even point: when as much energy comes out of a reaction as goes...
Funny how much difference a week or so can make. Eight days ago the universe-leading Red Sox were sighted somewhere on the far side of Mars, tooling for the World Series with all engines on full; now it looks like they might have been sold some bad liquid hydrogen by the shady character who runs the NASA-surplus parts shop down at Cape Canaveral. The thrust just isn't there. The Bosox have now lost seven of their last eight games, and their once-astronomical division lead has shrunk to a mere five-and-a-half games over...
