In 2000, the United States published seven mathematical problems of the Millennium. Who can solve any of these seven problems and directly take away $ 654.38+0 million?

Through this way of offering rewards to the public, it has attracted a large number of eager math lovers. Solve a problem, they can get away with it 1 million dollars, and they can become famous in the field of mathematics overnight. Various honors and extra income are enough to ensure their basic life for the rest of their lives.

But there is such a great mathematical god who solved one of the problems but gave up taking 1 10,000 dollars. Facing the reporter's question, he replied roughly: I'm not interested in money. I just solved a math problem and don't like being put in the spotlight by you.

This mathematical genius is Russian mathematician grigory perelman.

Perelman solved the problem of Poincare conjecture, which was put forward by French mathematician Poincare. This conjecture is as simple as one sentence: any simply connected closed three-dimensional manifold must be homeomorphic on a three-dimensional sphere. This kind of mathematical problem, people who can understand the problem, is already a high IQ among ordinary people.

Based on his own experience, Poincare thinks that this situation can be applied to any three-dimensional manifold, but he can't prove it himself. This conjecture was put forward by Poincare in 1904 and finally confirmed by perelman in 2006.

Perelman didn't solve math problems for money. Mathematics is as obsessed with him as an internet addiction teenager playing games. He began to study Poincare conjecture from 1995, and it took him seven years to solve this problem in 2002. At that time, perelman just uploaded his proof process as draft paper to a website and sent an email to a dozen mathematicians to see if it was correct.

Unexpectedly, this behavior caused a sensation in mathematics, and he was invited to MIT to explain it to mathematicians. The whole 90-minute proof analysis process made some people admire perelman from the bottom of their hearts.

Some mathematicians tried to prove that perelman was wrong, but after more than three years, no one found any problem, which was finally confirmed in 2006, and the problem that puzzled mathematicians for a century was solved!

Solving Poincare's conjecture, perelman can completely put on a suit and tie, and as a mathematician, he can go to a famous university to make money. Various invitations and positions are also overwhelming. Someone offered him a position of 1 working only 1 month a year, and the salary was determined by himself, as long as people appeared, but perelman finally refused it, just like he refused the 1 10,000 dollars of Millennium Mathematics.

Perelman refused more than that. He also rejected the 2006 Fields Prize in mathematics, which belongs to the same category as the Nobel Prize. Rejected the academician of the Russian Academy of Sciences recommended in 2004; Reject 1996 "Outstanding Mathematician Award" awarded by European Mathematical Society; 1996 rejected the employment of Stanford, Princeton and other research institutes; In 2005, he also resigned from all positions.

For several months, perelman has been working hard on mathematical problems. He has studied the Poincare conjecture for seven years, as if from scratch. He lives only by the savings accumulated in his previous job, and his life is very simple, and sometimes he is mistaken for a tramp.
