A Beautiful Mind...

But, a somewhat messy personality:

A maths genius who won fame last week for apparently spurning a million-dollar prize is living with his mother in a humble flat in St Petersburg, co-existing on her £30-a-month pension, because he has been unemployed since December.

....Grigory "Grisha" Perelman's predicament stems from an acrimonious split with a leading Russian mathematical institute, the Steklov, in 2003. When the Institute in St Petersburg failed to re-elect him as a member, Dr Perelman, 40, was left feeling an "absolutely ungifted and untalented person", said a friend. He had a crisis of confidence and cut himself off.

....Interviewed in St Petersburg last week, Dr Perelman insisted that he was unworthy of all the attention, and was uninterested in his windfall. "I do not think anything that I say can be of the slightest public interest," he said. "I am not saying that because I value my privacy, or that I am doing anything I want to hide. There are no top-secret projects going on here. I just believe the public has no interest in me."

He continued: "I know that self-promotion happens a lot and if people want to do that, good luck to them, but I do not regard it as a positive thing. I realised this a long time ago and nobody is going to change my mind. "Newspapers should be more discerning over who they write about. They should have more taste. As far as I am concerned, I can't offer anything for their readers.

"I don't base that on any negative experiences with the press, although they have been making up nonsense about my father being a famous physicist. It's just plain and simply that I don't care what anybody writes about me at all."
