(Via MetaFilter and L. Spice) The Sarong Theorem Archive is the premier online repository for pictures of mathematicans in sarongs proving theorems.

It talks about the proof of the Kepler conjecture being accepted into the Annals of Mathematics and what this means for the future of mathematics. The conjecture basically states that if you pack spheres into a box the same way oranges are [...]
