“For those who have trouble with a telephone number or with a name to fit a face, it is even problematical contemplating the gap between us and them, the normal and the genius. Someone once asked A. C. Aitken, professor at Edinburgh University, to make 4 divided by 47 into a decimal. After four seconds he started and gave another digit every three-quarters of a second: ‘point 08510638297872340425531914’. He stopped (after twenty-four seconds), discussed the problem for one minute, and then restarted: ‘191489’– five-second pause –‘361702127659574468 . Now that’s the repeating point. It starts again with 085. So if that’s forty-six places, I’m right.” — John Carey
