• On the topic of eigenvalues, this video is a very nice introduction: [VIDEO] (the whole playlist kicks ass; highly recommended for anyone interested in "seeing" what linear algebra is all about)

• 3Blue1Brown explanation of eigenvectors and eigenvalues is very insightful and intuitive [1]. One of my favorite videos from his channel is "Who cares about topology? (Inscribed rectangle problem)" [2]. They way a Torus and Möbius Strip come up as solution to the problem is so …

• A far easier to digest primer on eigenvalues is available from 3Blue1Brown [+]. His presentation format is undeniably approachable, so much so that I think you could probably use it to teach linear algebra and eigenvectors to 9-year olds. [+] [VIDEO]
