At lunch with a math friend years ago, he showed me an integral whose solution was, he said, so beautiful that it compelled him to become a professional mathematician. I scribbled the integral down on a napkin, but for the life of me I cannot remember the trick he found so compelling.
And these things are hard to Google...
$$ \int_{-\infty}^{\infty} e^{-x^2} dx $$
