Mathematician rejects prize of $1 million cash

Grigory Perelman, the Russian mathematician who cracked a century-old geometric conundrum that has eluded the world's sharpest brains, has rejected a $1 million prize.

Perelman, also known as Grisha, snubbed the cash on principle. He is famously reclusive and has a history of declining awards. His decision is believed to be due to his mistrust of his fellow mathematicians and their qualifications to administer such honors.

"The main reason is my disagreement with the organized mathematical community," Perelman told Interfax, the Russian news agency. "I don't like their decisions; I consider them unjust."
