As a first introduction, its more instructive to develop physical theories from physical postulates (like speed of light is constant), rather than constraining possible theories using more abstract mathematical principles.

Undergrads will not appreciate the latter, as much as they will the first. Especially, because in the third semester, where relativity is first introduced, most physics undergrads don't know any group theory.

I wonder if we taught Emmy Noether’s theorem in tenth grade if people would love physics more.
