…which this post is too small to contain.

In honor of Pierre de Fermat’s  410th (or maybe 403rd or 404th) birthday, Google’s homepage has a homage to Fermat and his famous Last Theorem:

Of course Fermat did much mathematics besides his Last Theorem.

For example, in Calc II you hopefully did the integral of $x$, $x^2$, and $x^3$ using formulas for geometric series.  It turns out that Fermat was the one who first developed this technique!  See here for a nice short history of doing integrals, including Fermat’s method.
