The end of the year (as well as a *Plus* birthday today) put us in the mood to reflect on mathematical milestones.

In recent years maths has hit the front page with Andrew Wiles' proof of Fermat's last theorem and Grigori Perelman's proof of the Poincaré conjecture. Maths has also hit the jackpot with the Google page rank algorithm, changing the way the we find information and the way we do business. And Thomas Hales' computer-aided proof of Kepler's Conjecture might signal the way mathematics will be changing in the years to come.
