Off-topic, but this whole website is a gold mine. I just finished reading "Coordinate-Free Linear Algebra" and "Hamiltonian and Lagrangian Mechanics", making tensor products, Lie derivatives and Poisson brackets finally click. Thermodynamics is next on my list.

If the author ever lurks here, thank you so much for putting these online!

I do! Thanks for the kind words. I'm happy to hear someone enjoyed the linear algebra article --- after I finished that one and heard from some people who tried to read it I ended up with the impression that I'd pitched it too hard, so it's nice to know someone got something out of it.
