The 20 greatest equations. Euler's equation is my pick for #1. It's got e, pi, i, 1, and 0...beautiful.

hmm, is sombody studying for the GLAT?

I am still thinking about fractals and whether Feingenbaum's constant can be put next to the Euler equation. So, I would go for Lorenz equations, as example of chaos.

richard feynmann thought that euler's equation was the "greatest", too. in the realms of physics, that's quite a vote.

Don't forget the fundamental operations: addition, multiplication, and exponentiation. Not to mention equality. It's got it all. His "other" equation can't be beat for sheer unexpected pull-it-out-of-a-hatness, though.
