How to intuitively understand eigenvalue and eigenvector?
Eigenvectors are like the roots of a polynomial. They constrain the transformation in particular ways.

If you have a line or plane which is invariant then there is only so much you can do to the surrounding space without breaking the limitations. So in a sense eigenvectors are not important because they themselves are fixed but rather they limit the behavior of the linear transformation. Each eigenvector is like a skewer which helps to hold the linear transformation into place.

A Beginner’s Guide to Eigenvectors, PCA, Covariance and Entropy

This post introduces eigenvectors and their relationship to matrices in plain language and without a great deal of math. It builds on those ideas to explain covariance, principal component analysis, and information entropy.
