...Einstein's discomfort with quantum theory make him less a candidate for Person of the Century? Not by much. His own work contributed greatly to quantum theory and to the semiconductor revolution it spawned. And his belief in the existence of a unified field theory could well be proved right in the new century...
...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...
Einstein continued to work on the problem in Berlin, undisturbed by domestic matters and largely unaffected by the war, until he finally found the right equations, in November 1915. Einstein had discussed his ideas with the mathematician David Hilbert during a visit to the University of Gottingen in the summer of 1915, and Hilbert independently found the same equations a few days before Einstein. Nevertheless, as Hilbert admitted, the credit for the new theory belonged to Einstein. It was his idea to relate gravity to the warping of space-time. It is a tribute to the civilized state of Germany...
...length and time). It also requires the existence of an entirely new class of subatomic particles, known as supersymmetric particles, or "sparticles." Moreover, there isn't just one string theory but five. Although scientists could rule out none of them, it seemed impossible that all of them could be right...
...working in physics today, declared that all five supersymmetric string theories represented different approximations of a deeper, underlying theory. He called it M theory. The insight electrified his colleagues and inspired a flurry of productive activity that has now convinced many that string theory is, in fact, on the right track. "It smells right and it feels right," declares Caltech's Kip Thorne, an expert on black holes and general relativity. "At this early stage in the development of a theory, you have to go on smell and feel...
