I'm friends with an incredibly smart kid. He's 14, but has been put up three grades in school at one point. He does all the obvious enrichment things which are available in the relatively small Australian city he lives in.
His life experience has been pretty unusual. He doesn't really know what it's like to be challenged in school. All his friends are way older than he is. (Once, I asked him how being constantly around people older than him made him feel. He replied, "Concerned for my future.")
He doesn't know anyone like him, which I think is a shame: he'd probably get along very well with them.
Does anyone know any similar kid geniuses? If so, can I give them my friend's details?
Thanks.

He starts solving the problem at the 9:50 mark.
He's supposed to prove that a certain infinite series converges, and he applies the integral test for convergence. It is of course extremely impressive that a 12-year-old would even think of doing this, but the test is clearly not applicable in this case. The summand function is neither non-negative nor monotone decreasing, both of which are requirements for the applicability of the integral test.
To be fair to him, though, they (unintentionally?) gave him a trick question. He was asked to prove that the series converges, but it actually doesn't. Also, I'm sure if I was put on the spot in front of a TV camera there's a high probability I'd make silly mistakes.
It is quite possible that he's improved markedly since then, and if he's a university student and published in Phys. Rev. A then I would guess he has.
Well my instinctive feeling would've been - this won't converge. The problem with people educated by tests. The tests imply there is an answer. In real world when you do something new you don't have clues like 'it converges'. When i was studying stuff, we just had fairly hint-less questions.
