Noether's theorem and Newton's Laws | Hugonweb Annotated Link Bibliography

A 2026 Physics Teacher paper by Eugene Hecht. Hecht wrote my intro physics textbook back in 2000.

I'm not sure the connection of Noether's theorem and Newton's laws is convincing, but the conceptual discussion of Noether's theorem is great.

Recall that invariance relates to the unchanging state of a quantity transferred between reference frames. Conservation relates to the unchanging state of a quantity in time, within a given reference frame. The two concepts are not equivalent.

I hadn't compared invariance and conservation before, and this is nice to think about.
