Rezension bezieht sich auf: Emmy Noether's Wonderful Theorem (Taschenbuch)
For some time already I was looking for a good introduction into the topic of Lagrangians, the Euler-Lagrange equations, the action integral and how they relate to symmetries and invariance. With a background more in mathematics than in physics, I found a few derivations that used too much physicist's math shortcuts that made it hard for me to follow.
This book has just the right mathematical rigor and detail to understand the derivations.
