>detailed discussion of this area is beyond the scope of this book. For additional material regarding this topic, the reader is referred to reference works on the subject.

In other words: the author is too much of a brainlet to present the topic

>oh boy, I can't wait to learn about a two-level spin system! maybe I'll calculate the energies of an electron in a magnetic field!
>w-wait, why is this getting into group theory? and quantum field theory? I just want to know how spins behave

Brainlet detected. You don't need group theory or QFT to understand spin.

detailed discussion of spin requires both topics. so you agree with me that a first year QM undergrad book doesn't need them then? and that the OPs point was stupid?
otherwise I'm not sure what your response means

Babby's first representation theory doesn't require group theory and can be expected to be covered in an undergrad intro to QM.

stop changing the argument. OP said "detailed discussion" and you're arguing for "brief introduction," when I was pointing out how stupid it would be for introductory textbooks to include detailed discussions on certain topics

Spin is a very simple subject for which a detailed discussion and a brief introduction are basically the same.

If you can present supplementary material in a page or two for the thing you are trying to present you are both failing as an author and scientist.
It is really that simple.

He's not wrong. There are some intricacies, but the basics are easy.

Oh boy, you retards sure forgot your Dirac's equation huh

I wouldn't call solving the Dirac's equation easy, but it sure as fuck doesn't require any group theory or qft
