...case you didn't get one, here are the holiday greetings the presidential types are mailing their many best friends. Counterclockwise from bottom, you'll find Hatch's card (with a Christmas song sheet inside), George W.'s (with a biblical message) and family portraits galore (McCain, Bauer, Gore, Keyes, Forbes, Buchanan); Bradley claims he didn't send cards. The most tastefully sedate one--can you believe it?--features a wreath from The Donald. But only the Clintons have the White House on theirs. That's why this mail is about keeping those letters and dollars coming...
...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...
Nature rarely bestows gifts on scientists, however, without exacting a price, and the price, in this case, takes the form of additional complications. Among other things, string theory requires the existence of up to seven dimensions in addition to the by now familiar four (height, width, 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...
...that, in fact, has turned out to be the case. In 1995, Witten, perhaps the most brilliant theorist 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...
...Newtonian heritage to us, in any case, is pervasive. W.H. Auden in 1939 wrote lines that might have been composed about, say, Kosovo last winter: "I and the world know/ what every schoolboy learns./ Those to whom evil is done/ do evil in return." What is that but Newton's third law of motion? Einstein's image of Newton as a child occurred, oddly enough, to Newton himself. Maybe that's where Einstein got it. Just before he died, Newton remarked, "I do not know what I may appear to the world; but to myself, I seem to have been...
