Quote of the Day
Einstein was only twenty-six when he invented spatial relativity in 1905, but do you know how old he was when he wrote his first paper on the speed of light? Fifteen or sixteen. That’s the magic ten years. It turns out that the time separating people’s first in-depth exposure to a field and their first world-class achievement in that field is ten years, neither more nor less by much. Einstein knew a hell of a lot about light rays and all sorts of odd information related to them by the time he turned twenty-six.
