Cavalier as he may have been about his wives, he had a deep moral sense. At the height of World War I, he risked the Kaiser's wrath by signing an antiwar petition, one of only four scientists in Germany to do so. Yet, paradoxically, he helped develop a gyrocompass for U-boats. During the troubled 1920s, when Jews were being singled out by Hitler's rising Nazi Party as the cause of Germany's defeat and economic woes, Einstein and his "Jewish physics" were a favorite target. Nazis, however, weren't his only foes. For Stalinists, relativity represented rampant...
...response to Germany's growing anti-Semitism, he became a passionate Zionist, yet he also expressed concern about the rights of Arabs in any Jewish state. Forced to quit Germany when the Nazis came to power, Einstein accepted an appointment at the new Institute for Advanced Study in Princeton, N.J., a scholarly retreat largely created around him. (Asked what he thought he should be paid, Einstein, a financial innocent, suggested $3,000 a year. The hardheaded Elsa got that upped to $16,000.) Though occupied with his lonely struggle to unify gravity and electromagnetism in a single mathematical framework...
...fixed speed through the ether. So if you were traveling in the same direction as the light, you would expect that its speed would appear to be lower, and if you were traveling in the opposite direction to the light, that its speed would appear to be higher. Yet a series of experiments failed to find any evidence for differences in speed due to motion through the ether...
...geometry of reality. What if space-time--an entity Einstein invented to incorporate the three familiar dimensions of space with a fourth dimension, time--was curved, and not 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...
...indication of God's freedom to start the universe off any way God wanted. Others (myself included) feel that the beginning of the universe should be governed by the same laws that hold at all other times. We have made some progress toward this goal, but we don't yet have a complete understanding of the origin of the universe...
