A Russian genius has turned down a $1 million (£660,000) prize for solving one of the world's most complex maths problems.Grigory Perelman, 44, was dubbed the world's cleverest man after solving the Poincare Conjecture - which had baffled mathematicians for more than a century.
By solving the problem - a theorem about the characterisation of the 3D sphere among 3D manifolds - he stood to receive £660,000 from the US-based Clay Mathematics Institute.
But Perelman says he does not need the money and he has previously refuse to accept the Fields medal (the Nobel prize of mathematics) for his work.
Perelman is said to live in a bare, cockroach-infested flat in St Petersburg… and before you ask, yes, he knows exactly how much one million is. A spokesperson for the Clay Mathematics Institute said: "The Poincaré conjecture is one of the seven Millennium Prize Problems established by CMI in 2000.
"The Prizes were conceived to record some of the most difficult problems with which mathematicians were grappling at the turn of the second millennium."
The man is a recluse. How does anyone know his apartment is infested? Pathetic.
