I began to write an acerbic comment at "everything is a spring". I then thought about it, and realised you're so right. Linear algebra is crazy. Thank you for the insight. (It struck me that all of quantum mechanics I've ever studied in university was about learning to solve more sophisticated harmonic osciollators.)
