THE VIDEO SHELF · euler's identity
e^(iπ) in 3.14 minutes, using dynamics | DE5
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.

In Ask HN: What YouTube channels do you subscribe to?3Blue1Brown's video "Understanding e to the i pi in 3.14 minutes" is a nice compliment to this post. [VIDEO]

In Why is e^(pi I) = -1?IMHO, the "deeper truth" is addition is translation and multiplication is rotation/stretching (at least when it comes to rings and fields). It involves getting a geometric understanding of e to the pi i, and 3blue1brown explains it better than I could: [LINK] [6.28 min] [VIDEO] …
