Eigenvectors and eigenvalues | Chapter 14, Essence of linear algebra
3Blue1Brown
3Blue1Brown's chapter on eigenvectors and eigenvalues in the Essence of Linear Algebra series. It builds a visual intuition for what they mean, why an eigenbasis is useful, and ends with a puzzle.
HN repeatedly names it the best, most intuitive explanation of eigenvalues, and a gateway to the whole linear algebra series.
