Perelman is in news again. After three years of proof checking, mathematicians are convinced that this guy has indeed cracked the conjecture.
Apparently, this unwordly genius is "missing" somewhere in Russia and is not responding to emails. People have also started conjecturing tha he will turn down the Clay Math million dollar prize and the prestigious Fields Medal, which he will most likely receive next tuesday.
NY Times (free subscription maybe required) has a nice article on the problem, its history and Perelman. Click here for a related article by Simon Singh.
For the mathematically inclined, Bruce Kleiner and John Lott have a page with materials related to Perelman's work on Ricci flow.
