【简答题】

A maths talent who won fame this week for giving up a milliondollar prize is living with his mother in
a flat in St Petersburg, coexisting on her £ 30amonth pension, because he has been
unemployed for many years.
The Sunday Telegraph tracked down the strange recluse(隐士) who shocked the maths world
when he solved a centuryold puzzle known as the Poincar? Conjecture.
Grigory Perelman's trouble comes from a split with a leading Russian mathematical institute, the
Steklov, in 2003. When the Institute in St Petersburg failed to reelect him as a member, Dr Perelman
was left feeling an 'absolutely ungifted and untalented person', said a friend. He became unconfident
and cut himself off.
Other friends say he cannot afford to travel to the International Mathematical Union's congress in
Madrid, where many people want him to receive the maths equivalent(等价物) of the Nobel Prize, and
that he is too modest to ask anyone to pay for his trip.
Interviewed in St Petersburg, Dr Perelman insisted that he was unworthy of all the attention, and
was uninterested in the prize. '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 topsecret projects going on here. I just believe the public has no interest in me.'
He continued: 'I know that selfpromotion 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 realized this a long time ago and nobody is going to
change my mind.Newspapers should be more discerning(有洞察力的) over who they write about.
They should have more taste. As far as I am concerned, I can't offer anything for their readers.'
Dr Perelman has some small savings from his time as a lecturer, but is apparently unwilling to increase
them with the D$1 million offered by the Clay Mathematics Institute in Cambridge, Massachusetts,
for solving one of the world's seven 'Millennium Problems'.
