Going through this material in school the first time was like driving a jalopy down a bumpy dirt road. Seeing Professor Brunton's crystal clear explanations of the same material now is like driving a Cadillac down a newly paved 4 lane highway. These presentations are invaluable and I envy students today who have access to Dr. Brunton's extraordinary library of lectures.

A such relationship between the diagonalization of a matrix and the specific tone of a guitar string is something that has alway amazed me! How is it possible that just by transforming a matrix, we can describe the reality? Nature is not a mathematician who calculates the eigen values and eigen vectors of a huge matrix! I don't understand what is this mysterious link between matrix computation and the physical world...

Best explanation I've heard, on motivating eigenvalue and eigenvectors. When I was first introduced to it, it was just an equation, to define what it is (A*V = L*V). Yeah, there was the mention of basis vectors, and diagonal matrix. But the motivation is to simplify things, keep things clean. The zoo metaphor is a good one. Does one want everything nicely organized, dealing with one animal at a time, or is it the whole confusing mess, with everything interacting with everything else, out in the wild.

For a more mathematical approach to this topic, I'd recommend "L. Sadun, Applied linear algebra. The decoupling principle. 2nd ed. Providence, RI: American Mathematical Society (AMS) (2008; Zbl 1140.15001)". The videos for this book are also on KZread: kzread.info/head/PLZcI2rZdDGQrb4VjOoMm2-o7Fu_mvij8F

Wow! That is a mind blowing class. Thank you! It is always a challenge to link topics in math, but when done it is beautiful. I would say everytime some piece of math is teached it should come up along some motivation, why that tool will be needed somewhere in the future. I remember how useless was to invert matrices in high school or learning eigen-stuff on second semester of college. It is satisfying getting things together!

This video is really really cool! I've ever found the equation A*V = Lambda*V (The same one as the last equation you wrote) from some text book but not found the Eigenvalue system equation (which contains multiple A*V = Lambda*V equations) like this. Could you please suggest/share which text book I can find this Eigenvalue system equation?

Hello Professor, it's really a nice video! I have a small question here, sometimes we have an ill-conditioned system matrix A, and when we do the eigenvalue decomposition, we will inevitably meet small and large eigenvalues (eigenmodes). This kind of system may sensitive to small errors during time evolution. Do you think it's a good idea to do some mode truncations to neglect some fast dynamics in the system?

Well, it depends on what you are interested in. That's what is done in dominant pole approximation for example (large negative eigenvalues, i.e. fast dynamics, are neglected)

I like the idea, but it sort of misses the full scope of what eigenvalues and eigenvectors are. Indeed, if you have a system of distinct eigenvalues which are all present in your ground field, then you've got the result here. However, the fact diagonalization is not always the case despite the existence of eigenvalues and eigenvectors means that defining eigenvectors in terms of diagonalization doesn't actually make mathematical sense. It's a great motivation, but I'd expect to see the other cases handled in a similarly geometric fashion to show exactly what those cases entail.
