Not all child geniuses are in a rush to get to the PhD finish line. Norbert Weiner was originally a mathematics prodigy, finishing his bachelor's degree from Tuft's College at the age of 14. In graduate school he switched to zoology before his father steered him back toward mathematics and philosophy. Weiner received a PhD in Mathematical Logic from Harvard when he was 17. He went on to coin the term "cybernetics" and work in automation, journalism and communication theory.
