Goodstein theorem

[sid-code]

If you want some exotic, graduate level math that isn't too hard to understand, check out Goodstein's theorem. This is probably the single most astonishing math result that you can explain to someone who only knows middle school math.

The MathWorld page on Goodstein sequences is also a good start.
