Quantum Theory, Groups and Representations

   I'd recommend

   Physics From Symmetry by Jakob Schwichtenberg

   Also, (though I've not read it) this appears to be a longer, more detailed text in the same vein:

   Quantum Theory, Groups and Representations: An Introduction by Peter Woit

   This one gets to the EM field on page 573 :-/

   This reminds me of Peter Woit, a theoretical physicist who has written a book on "Quantum Theory, Groups and Representations", asking if QM is a probabilistic theory.

   By the way, this example illustrates the point I made in another comment: you can have a long career in physics and even become professor of theoretical physics without ever caring about the interpretation of QM.

   Edit: I can't resist copying the opening of a recent comment in that thread.

   And perhaps no physics here, either, unless we say how the state of the world is described by that vector: that is, how we can use the vector to make predictions of experimental results.

   (A long and insightful comment by Baez follows)
