Post math that blows your mind.

>the series expansion of 1/(1+x^2) around 1 has a radius of convergence √2 because this is the distance between 1 and the function's nearest singularity (which is at i) when you view x as an element of the complex plane
>if two functions are holomorphic on a connected open set D and the functions are equal on a subset of D that has a limit point inside D, then the functions are equal on the entirety of D
>if f(1/n)=g(1/n) for all n then f=g everywhere
>the value of a holomorphic function at a point is completely determined by averaging the function's values around a random loop enclosing that point
>the reals don't exist

How useful Tarski's fixed point theorem is compared to how simple it is.
