Euler's identity blew me away when I first learned it a year ago:

e^iĻ€ + 1 = 0

This is mine too. How is it possible that

   * the ratio between the a circle's circumference and diameter
   * the number such that the derivative of e^x = e^x
   * the square root of negative 1
Have anything to relate them to one another?? That last one isn't even a number!

Mind. Blown. The universe is one crazy place.

which also means that ln(-1) = i*pi

o, and another cool one is (1/2)! = sqrt(pi)
