...consequence of relativity is the relation between mass and energy. Einstein's postulate that the speed of light should appear the same to everyone implied that nothing could be moving faster than light. What happens is that as energy is used to accelerate a particle or a spaceship, the object's mass increases, making it harder to accelerate any more. To accelerate the particle to the speed of light is impossible because it would take an infinite amount of energy. The equivalence of mass and energy is summed up in Einstein's famous equation E=mc2, probably the only physics...
...generally regarded as a sort of petrified object, rendered deaf and blind by the years," Albert Einstein confided near the end of his life. He was, alas, correct. During the last three decades of his remarkable career, Einstein had become obsessed by the dream of producing a unified field theory, a series of equations that would establish an underlying link between the seemingly unrelated forces of gravity and electromagnetism...
Still, today eBay is one of the most dazzling sites on the Internet. Log on and feast your eyes on a global garage sale that includes--well, just about any inanimate object you've ever seen, heard of or lusted after. That Partridge Family lunch box that made you feel like the Man in third grade? The bidding starts at $5. That Art Deco clock you always wanted? There were recently 19 of them being auctioned on eBay. Sure there's kitsch (Elvis snow globes, anyone?), and a scary number of Beanie Babies. But there's also luxe (usually...
...illusion that has appeared in very different guises to different groups. Says Greenwich observatory director Kristen Lippencott, who put together the British exhibition: "Time is not the thing on our wrists. Time is a cultural object." For many outside the Western European tradition, for instance, time is a circle that turns on a daily, yearly and even a cosmic scale. The Hindu concept of reincarnation is perhaps the most familiar example, but the Hopi in the American Southwest and the Inuit in the Arctic also look at the world as a series of repeating cycles with no beginning...
...came up with when he had a similar problem: "Definitely Not the Dumbest Guy in the Deke House." Political pundits are warning us that the public is in danger of seeing all the presidential candidates as caricatures--McCain as a hothead, for instance, and Gore as a manlike object and Forbes as a terminal dork. Just who might be responsible for leaving the voters with these impressions is not the sort of question political pundits bother their pretty little heads about. It may be worth noting, though, that in recent weeks the New Republic has carried cover drawings of Bush...
