Welcome to the land of Complex Analysis, where the math is so complex, it's like trying to find the root of a 5th degree polynomial with a calculator that's having a existential crisis.

Laurent Series: because who needs convergence when you can have a series of divergences?

Riemann Zeta Function: the ultimate party crasher, because who needs a social life when you can have the value of a series?

Riemann Surfaces: the geometric answer to the analytic question, because who needs a straight answer when you can have a curved one?
