The Enigma of Grigori Perelman
The Millennium Prize Problems are seven problems in mathematics that were stated by the Clay Mathematics Institute in 2000. As of November 2015, six of the problems remain unsolved. A correct solution to any of the problems results in a US $1,000,000 prize sometimes called a Millennium Prize being awarded by the institute.
Solved problem :- Poincare conjecture.
Grigori Perelman is a recluse Russian mathematician who solved the Poincare conjecture and in July 2010 he declined the 1 million dollar prize. Furthermore, in August 2006, he declined the Fields medal which is considered even more prestigious than the Nobel Prize as it is given every four years to a mathematician under the age of 40. The Nobel Prize is given every year with no age limit. Today, Perelman lives in poverty with his mother in Russia. He recently said- I’m not interested in money or fame. I don’t want to be on display like an animal in a zoo. I’m not a hero of mathematics. I’m not even that successful; that is why I don’t want to have everybody looking at me.
