## Main Question or Discussion Point

**Perelman, Poincare Conjecture solved now??**

Seems that this guy has solved the Poincaré Conjecture:

http://en.wikipedia.org/wiki/Grigori_Perelman

He is supposed to get the Fields Medal in Madrid this year, in the next international congress of mathematics. But it is likely that he won't show up.

Is anybody able to give a plain explanation of the conjecture to an engineer?

Thanks in advance.
