>What's the source for some of those claims? Googling it, it seems like the claim that he taught himself to read when he was "a little over two" (ie not literally 24 months) has been repeated among multiple reputable news sources (New York Time, SMH, The Age). No comment on the IQ. >Calculus at seven I can believe, but teaching himself reading at 2 sounds like something that goes against what we know about biological and social development of the child. It doesn't seem too far-fetched, to be honest. Back when my wife worked in child-care, she knew this one kid who was speaking in multi-word sentences at 9 months old. Most kids don't reach this milestone until they're 2 1/2. Kids can and do surprise you.
