　　The Centurys Greatest Minds

　　Albert Einstein

　　The scientific touchstones of the modern agethe Bomb, space travel, electronics, Quantum physicsall bear his imprint. Einstein had conjured the whole business, it seemed. He did not invent the thought experiment, but he raised it to high art. Imagine twins , wearing identical watches; one stays home, while the other rides in a spaceship near the speed of light little wonder that from 1919, Einstein wasand remains todaythe worlds most famous scientist. In his native Germany he became a target for hatred . As a Jew, a liberal, a humanist, an internationalist, he attracted the enmity of rationalist and anti-semites. His was now a powerful voice, widely heard, always attended to , especially after he moved to the U.S. He used it to promote zionism, pacifism, in his secret 1939 letter to Franklin D. Roosevelt, the construction of a uranium bomb. Meanwhile, like any demigod, he made bits of legend: that he failed math in school . That he opened a book and found an uncashed $1,500 check he had left as a bookmark .That he was careless about socks, collars, slippers that he couldnt even remember his address: 112 Mercer Street in Princeton, where he finally settled. He died there in 1955 And after the rest of Einstein had been cremated, his brain remained, soaking for decades in a jar of formaldehyde belonging to Dr. Thomas Harvey. No one had bothered to dissect the brain of Freud, Stravinsky or Joyce, but in the 1980s, bits of Einsteinian gray matter were making the rounds of certain neurobiologists, who thus learned absolutely nothing. It was just a brainthe brain that dreamed a plastic fourth dimension, that banished the ether, that released the pins binding us to absolute space and time, that refused to believe God played dice. In embracing Einstein, our century took leave of a prior universe and an erstwhile God. The new versions were not so rigid and deterministic as the Newtonian world. Einsteins. God was no clockmaker, but the embodiment of reason in nature. This God did not control our actions or even sit in judgment on them. This God seemed rather kindly and absentminded, as a matter of fact . Physics was free, and we too are free, in the Einstein universe which is where we live.

　　Einsteins Theory of Relativity

　　Special Relativity

　　Relativity says that light always moves in a straight line through empty space, and always at the same speed in a vacuum, no matter what your observation point. From these simple claims follow bizarre consequence that challenge common sense and our perception of reality.

　　 A moving clock runs slower than a stationary one from the perspective of a stationary observer.

　　 A moving object appears to shrink in the direction of motion, as seen by a stationary observer

　　General Relativity

　　In general relativity, time is considered a dimension like height, width and depth, creating a four dimensional universe called space-time. Einstein argued that gravity is really a warping of space-time,with the greatest distortions near the most massive objects. Because light travels in a straight line through the contours of space-time, a light beam will curve where space-time curves, this curving was first measured in 1919
