The Twin Prime Hero

Yitang “Tom” Zhang spent the seven years following the completion of his Ph.D. in mathematics floating between Kentucky and Queens, working for a chain of Subway restaurants, and doing odd accounting work. Now he is on a lecture tour that includes stops at Harvard, Columbia, Caltech, and Princeton, is fielding multiple professorship offers, and spends two hours a day dealing with the press. That’s because, in April, Zhang proved a theorem that had eluded mathematicians for a century or more. When we called Zhang to see what he thought of being thrust into the spotlight, we found a shy, modest man, genuinely disinterested in all the fuss.

On solving an unsolvable problem :

Q : Did you experience any emotions when you realized you’d solved the problem?
A : Not so much. I am a very quiet person.

Q : Were you excited?
A : A little. Not too much.

Edit : Here’s a link to a documentary on Yitang : Counting From Infinity.
