Terry Taapurilim: The Top Guy in Mathematics

Terry Taapurilim is one of the world's leading mathematicians. He was already a top gun when he was like 16 or 17, so still cracking new things. His polymath project uses crowdsourcing to find subjects that could benefit from lots of people working on it. It doesn't work for all mathematics, but for some problems, it works really well where lots and lots of different people are doing lots of little different bits.
