The first principle is that you must not fool yourself — and you are the easiest person to fool. - Richard Feynman.

$\dfrac{1}{\pi} = \dfrac{2 \sqrt{2}}{9801} \displaystyle \sum _{k = 0}^{\infty} \dfrac{(4k)! (1103 + 26390k)}{{(k!)}^4 {396}^{4k}}$

Oh, you're wondering what the above is? It's simply one of Ramanujan's infinite series that converges to the reciprocal of $\pi$.

A love of form, an art, that's what interests me.
