...flat, as had been assumed? His idea was that mass and energy would warp space-time in some manner yet to be determined. Objects like apples or planets would try to move in straight lines through space-time, but their paths would appear to be bent by a gravitational field because space-time is curved...
...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...
Einstein could never accept that the universe was at its heart a cosmic crapshoot, so that today his papers on unified field theory seem hopelessly archaic. But the puzzle they tried to solve is utterly fundamental. In simply recognizing the problem, Einstein was so daringly far-sighted that only now has the rest of physics begun to catch up. A new generation of physicists has at last taken on the challenge of creating a complete theory--one capable of explaining, in Einstein's words, "every element of the physical reality." And judging from the progress they have made, the next...
What would Einstein have made of such wild imaginings? Columbia's Greene, for one, thinks he would have loved them. After all, Greene notes in his recently published book, The Elegant Universe, Einstein played around with the idea of extra dimensions as a strategy for producing a unified field theory...
...conqueror--unless the myth was an omen for living like a wild animal in the steppes around Lake Baikal. His father Yesugei was poisoned by enemies and his widowed mother Hoelun chased away from their tribe with her brood, including her eldest, nine-year-old Temujin. The outcasts ate field mice and marmots even as they fought off thieves out for their horses, the most precious of nomad property. Bitterness cultivated a heart of iron. After a half-brother grabbed a fish he had hooked, Temujin would kill the offending sibling in a hail of arrows. He never showed remorse...
