Looks like the interview may be fake:
http://english.pravda.ru/society/stories/06-05-2011/117816-grigori_perelman-0/
Also from Pravda.
The following paragraph is a quote, but I can't figure out how to make them in replies:
Moreover, it seemed "impossible and bizarre" for the blogger that Perelman was speaking about the "Poincare conjecture" in the interview. "He solved the conjecture, so it becomes a theorem," the blogger wrote on his webpage. "All those thoughts about nanotechnologies and the ideas of filling hollowness look like rabbi's thoughts about pork flavor properties." The critic stressed out that fundamental science prefers to say that all of that does not have applied relevance, which is the point of it all."
Looks also like there are some aspects of the "interview" not shared in Pravda, like this stuff about nanotechnology.
I'm not sure if that last sentence (of the quoted paragraph) is true or not.
Check out help link in bottom right of reply box.
Grigori Perelman was that reclusive Russian mathematician who proved the Poincaré conjecture, and refused the $1,000,000 prize. He has reportedly said that he refused the reward because he knows "how to control the universe" (full quote below; article linked at end).
My immediate thought is that he refers to the fact that understanding of the world means control of the world, to the extent of your understanding and limit of possibility. Thus the saying "knowledge is power" (which, oddly, the public doesn't really think seems to apply to science). I also see the point of refusing to communicate with the media, which manifestly does not care about science but rather about celebrity (I'm not guilty! this post is just about his ideas, dammit!). But his other comments - about the "boundless", for instance - sound more wild-eyed and vague, so maybe he's thinking of something else.
Also, what is this nonsense at the end? I think it's probably a misinterpretation by a reporter. Or wild exaggerations by Perelman. Or are we all doomed to be folded?
