Genius

A controversial proof of a 102-year-old mathematical puzzler has taken the top spot on the journal Science's annual list of scientific breakthroughs. Other entries on the top 10 list ranged from the deciphering of Neanderthal DNA to studies of the world's shrinking ice sheets. But it was Russian mathematician Grigory Perelman's proof of the Poincare Conjecture, literally one of the field's million-dollar challenges, that most impressed America's premier peer-reviewed science publication.

I know. What could possibly beat Neanderthal DNA!!?! I tried to follow the Poncaire controversy earlier this year. But I never really understood the proof until I saw this cover. It's a way to turn dumbells into balls. Science is awesome.
