e^(iπ) in 3.14 minutes, using dynamics | DE5
3Blue1Brown
A short 3Blue1Brown video explaining Euler's formula e^(i*pi) = -1 through dynamics, treating velocity as the thing that moves a point to a new position. It builds geometric intuition for why an exponent with i produces rotation.
HN commenters point to it as a quick, visual way to understand Euler's identity.
