Prime Number Theorem

Hadamard and de la Vallée Poussin prove (1896) that primes thin out like 1/ln n, using Riemann's complex zeta function.

Gauss guessed the law as a teenager, Riemann's 1859 memoir tied primes to the zeros of the zeta function, and the 1896 proofs used complex analysis. The theorem tells us that large primes are plentiful, which public-key cryptography relies on, and it frames the open Riemann Hypothesis.
