Perelman

Peter Woit has more links to stories about Grigory Perelman, the mathematician who seems to have proved the Poincare Conjecture. One of them, in The Telegraph, tells a pretty grim story.
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.

The Sunday Telegraph tracked down the eccentric recluse who stunned the maths world when he solved a century-old puzzle known as the Poincaré Conjecture.

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.

Other friends say he cannot afford to travel to this week's International Mathematical Union's congress in Madrid, where his peers want him to receive the maths equivalent of the Nobel Prize, and that he is too modest to ask anyone to underwrite his trip.

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."

Sylvia Nasar (who wrote A Beautiful Mind) is on the case. She and David Gruber have a piece in this weeks New Yorker, which, unfortunately, is not on line.

Anti-Libertarian: re-post

The most pointed critique of social security and liberalism in general is the libertarian critique. The problem with libertarians, for a liberal, is that we have too much in common. We both believe in individual rights, tolerance of individual differences, and dislike government prescription of religion. The basic difference, it seems to me, is the different answers we give to Cain's (with thanks to the Captain - my original version had the corpse asking the question!) famous question: "Am I my brother's keeper?" That's not really my basic bitch against the libertarians though. My real complaint is the same as my complaint against most religion - its premise is a fraud. For those who can't stand to wait for the punchline, I believe that trying to implement libertarian principles leads to tyranny or social disintegration. Demonstrating that takes some historical (and pre-historical) context. For all but the last 15,000 or so of the 100,000 years the human spec

Uneasy Lies The Head

Uneasy lies the head that wears a crown ........... Shakespeare Henry IV, Part II. So it is with us and our slightly distant primate cousins , so it seems. A 9-year study of wild baboons in Kenya by Princeton University and the Institute of Primate Research may turn conventional assumptions of alphas males upside down. The study found that alpha males have high testosterone levels, which allows them to dominate other baboons, get access to more food, and attract better mates. This is expected. Surprisingly, though, the alpha males also have high levels of stress hormone glucocorticoid, which scientists measured from their feces samples. In fact, the stress of alpha baboons was on par with low-ranking baboons. The convention wisdom is that access to food and females provides life security and thus less stress for dominant males. Conversely, weak males who are constantly threatened by starvation and physical violence from stronger males are thought to be more stressed. The st

We Call it Soccer

The US played its best, and maybe only good game of World Cup, but lost thanks to brilliant goalkeeping by the Swedish keeper and the bizarre method soccer uses to settle ties when three US stars could not put the ball on frame from the 12 yard spot.  At the end it came down to a blocked shot that spun in by maybe a couple of centimeters. Well, that's football - too much like life.   Which brings me to a modest proposal.  Replace the thirty minute overtimes with as many 7-player 15 minute periods as needed to settle it.  Scoring should be much easier with fewer players.
