That's completely normal and very unfortunate. I only learned about the geometry of the eigen*s from an EE professor who loved math. Unfortunately, the history of the eigen*s is rooted in the opaque and cryptic (but rigorous) linear algebra definition, and the non-rigorous but meaningful geometry came later.
