To me, it's Euler formula: e^(iπ) + 1 = 0. It combines three most important constants of mathematics into one formula. Sweet !

  that...isn't true. The standard form of Euler's identity is e^(iπ) + 1 = 0. Of course, all the cool kids nowadays use e^(iτ) = 1. ;)

    Ohh, my mistake. Thank you for correction.
