The Mind that Changed The World

George Will’s column in today’s Washington Post is about Albert Einstein.

One hundred years ago a minor Swiss civil servant, having traveled home in a streetcar from his job in the Bern patent office, wondered: What would the city’s clock tower look like if observed from a streetcar racing away from the tower at the speed of light? The clock, he decided, would appear stopped because light could not catch up to the streetcar, but his own watch would tick normally. “A storm broke loose in my mind,” Albert Einstein later remembered.
