...young women. Nevertheless, he became not just a political force but a spiritual guide for those repelled by the hate and greed that polluted this century. "Generations to come," said Albert Einstein, "will scarce believe that such a one as this ever in flesh and blood walked upon this earth...
...most careful and accurate of these experiments was carried out by Albert Michelson and Edward Morley at the Case Institute in Cleveland, Ohio, in 1887. They compared the speed of light in two beams at right angles to each other. As the earth rotates on its axis and orbits the sun, they reasoned, it will move through the ether, and the speed of light in these two beams should diverge. But Michelson and Morley found no daily or yearly differences between the two beams of light. It was as if light always traveled at the same speed relative...
...number of experiments, including one in which an extremely accurate timepiece was flown around the world and then compared with one that had stayed in place. If you wanted to live longer, you could keep flying to the east so the speed of the plane added to the earth's rotation. However, the tiny fraction of a second you gained would be more than offset by eating airline meals...
...didn't begin to think seriously about the problem until he was at the German University in Prague in 1911. He realized that there is a close relationship between acceleration and a gravitational field. Someone in a closed box cannot tell whether he is sitting at rest in the earth's gravitational field or being accelerated by a rocket in free space. (This being before the age of Star Trek, Einstein thought of people in elevators rather than spaceships. But you cannot accelerate or fall freely very far in an elevator before disaster strikes...
...France's worst storm in this century highlighted an advanced industrial society's vulnerability to nature's wrath. "The sight of toppled steeples and chimneys and craters opening up in old structures all over Paris after a storm makes you wonder what a small earth tremor could do to this city," says Crumley. "In the end, it's a sign that nature can't be totally leashed or predicted." At least Mother Nature had the good grace to strike a week before the New Year - had the storm come amid Friday night's planned outdoor celebrations in Paris, the death...
