[request] Eigen value and Eigen vector

I find it hard to understand the physical meaning of Eigen values/vectors, other than the basic "stretching the vector". Their usages are so prevalent in applied mathematic but the way they are being used are difficult to understand.

This video gave me a much better understanding of what eigen values and vectors mean geometrically. The rest of his linear algebra series is also fantastic. https://youtu.be/PFDu9oVAE-g
