Book with Good Discussion of Noether's Theorem?

[MissSilvy]

I'm looking for a book that approaches it from preferably a physics slant (in terms of invariance, conserved quantities, and the like) but every mechanics textbook I've looked at gives a poor description. They're heavy on the math but they lack explanation or discussion of the results.

Neuenschwander's "Emmy Noether's Wonderful Theorem" is a nice discussion of the theorems and applications along with some biographical information. Kosmann-Schwarzbach's "The Noether Theorems" has a translation and discussion of the 1918 paper and is a much more historical treatment of influence of the theorems. Both are advanced undergraduate texts.
