Like about four years ago, the name of Grigoriy Yakovlevich (Grisha) Perelman is again in the mass-media headlines all around the world.
Grisha is a prominent mathematician, who was able to solve one of the most perplexed mathematical problems of the last two centuries: he had managed to prove the Poincaré conjecture.
In 2006 he was awarded the prestigious Fields Medal
, but had voluntarily and expressly refused to accept it.
Most recently, he has been awarded the not less prestigious Clay Millenium Prize
, but is expected to reject this award as well.
