...that 1905 paper, Einstein pointed out that because you could not detect whether or not you were moving through the ether, the whole notion of an ether was redundant. Instead, Einstein started from the postulate that the laws of science should appear the same to all freely moving observers. In particular, observers should all measure the same speed for light, no matter how they were moving...
...still at the patent office in Bern, but didn't begin to think seriously about the problem until he was at the German University in Prague in 1911. He realized that there is a close relationship between acceleration and a gravitational field. Someone in a closed box cannot tell whether he is sitting at rest in the earth's gravitational field or being accelerated by a rocket in free space. (This being before the age of Star Trek, Einstein thought of people in elevators rather than spaceships. But you cannot accelerate or fall freely very far in an elevator before...
...theory of relativity was readily mistranslated as a justification for relativism says more about the way the world was already tending than about Einstein. His stature gave an underpinning to ideas that had nothing to do with his science or personal inclinations.

For the rest of us, his image offers something much simpler--a shining set of ideals to emulate. Individual freedom. Political liberty. Social justice. Nonviolent protest. Passive resistance. Religious tolerance. His work and his spirit awakened the 20th century to ideas that serve as a moral beacon for all epochs...
