π 隐藏在素数的规律中Pi hiding in prime regularities

3Blue1Brown shows how pi emerges from prime numbers via complex numbers and sums of squares, culminating in a formula for approximating pi.

Why HN likes it: Praised as a beautiful, understandable proof and a favorite among 3Blue1Brown videos.

“This is a really beautiful proof that connects complex numbers and primes to derive a formula for calculating pi.”
