What it is

Numberphile talks with Grant Sanderson of 3Blue1Brown about a darts puzzle with a shrinking bullseye. Solving it takes the volumes of high-dimensional spheres, and the answer turns up Euler's number.

Why Hacker News recommends it

Used as a friendly example of high-dimensional geometry showing up in a simple problem, and of ball volume shrinking inside a hypercube.
