This kid is such a stud. I had the honor of meeting him at a conference a few years ago when he was only 11 or 12. He answered questions about math like an intelligent grad student, conveying his own ideas in fully grammatical sentences without ums or ahs. It was as if he were reading from a textbook on the subject that he had written. One of the presenters called him on stage and tried to tease him a bit, but he was utterly un-phased by it, and gave intelligent, straightforward replies.
