Relativity General relativity with focus on action?

AI Thread Summary
The discussion centers on the approach to teaching general relativity through the action principle and variational methods, highlighting the importance of deriving equations of motion from the action of fields. Participants recommend several books that emphasize this methodology, including Landau and Lifshitz's volume 2, which effectively uses the action principle to derive the Einstein field equations. The Hilbert action is noted as a fundamental heuristic argument for understanding the structure of these equations. There is a debate about the use of the term "heuristic," with some arguing that Hilbert's approach is more formal compared to Einstein's intuitive development. Overall, the action principle is seen as a versatile and intuitive tool for understanding the dynamics of general relativity.

I am having a class of general relativity. It seems that the professor will follow an approach which consist of achieve the action, and variate it to get the equations of motion (indeed, that's how we already got the geodesic equation, the dynamics of a particle in electromagnetism, the equation of the fields itself, and the action of massless particle, etc...). Do you know any book that follows such approach? That is, a book that focus mainly on the action of the fields itself.

Nearly every book on GR discusses the action: Carroll, Wald, d'Inverno, etc. Which book do you use?
 
My favorite for introductory GR is Landau+Lifshitz vol. 2. He uses the action principle to derive the Einstein field equation. The Hilbert action is the most simple heuristic argument for why these equations should look as they look.

Introduction to General Relativity by Bambi.

Excerpt from a book description:

"Following the approach of Lev Landau and Evgenii Lifshitz, this book introduces the theory of special and general relativity with the Lagrangian formalism and the principle of least action."

I found the book quite readable and going
straight to its object.

I agree that LL vol 2 is good. You mention Hilbert action as a heuristic argument. Is heuristic the right word here. I thought of Einsteins intuitive manner of developing his equations as heuristic. I would regard Hilbert's development as quite formal.
 
What you call "heuristic" is pretty much a question of your preknowledge. For me the action principle is the most versatile tool to guess equations of motion given a symmetry principle and I think it's much more "intuitive" or "heuristic" than Einstein's derivation.
