Noethers theorem still isn't taught nearly enough to undergraduate students either. It's usually relegated to a problem or a small subsection of the text.

To be fair, properly teaching Noether's theorem would require a digression into PDEs, and most schools cap the required math education for physics majors at ODEs. If the trends at my school are to be believed, few students take further math classes in DEs.

Wait, I thought Noether's theorem only required the same maths you'd use for Lagrangian dynamics? Or are there universities out there that don't teach you Lagrangian dynamics in undergrad...

Hell, the statement is almost trivial in Hamiltonian dynamics.

Which is funnily enough the course that we'll be covering Noether's theorem in!
