One day, he started to keep remembering digits of pi, by the next day he remembered the first 30, the next week, he remembered almost 1000 digits.

A cursory Google search points to Jordan Ellenberg's book "How not to be wrong," where he acknowledges hearing this from his PhD adviser, but calls it "a common piece of folk advice" without identifying a definitive source.Dustin Mixonhttp://dustingmixon.wordpress.comnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1079324037347594142018-11-26T11:33:18.086-05:002018-11-26T11:33:18.086-05:00If there were a counterexample to Goldbach that di...If there were a counterexample to Goldbach that didn't "require hard math" wouldn't it have been found by now?
