Perelman, who I find adorable by the way, is described in this documentary - in Russian, with English subtitles - as a national hero.
I find the movie deeply poetic; so musical in fact that I want to learn mathematics or - who knows - do mathematics.  I'm just not sure how to proceed.

A butterfly flutter from afar reaches the ear to whisper and stir the belly like a song wake up drive yo!
