      French mathematician Pierre de Fermat wrote a “little theorem” in 1640 that is now the basis of modern computer cryptography.

      The Fast Inverse Square Root is an algorithm that estimates 1/sqrt(x), a very important calculation in computer graphics. Early computers struggled when calculating this value but a programmer solved this mathematical problem…while programming Quake 3. His solution to the problem wasn’t discovered until the source code for the game was released.
