Reddit mentions of Introduction to Quantum Mechanics

I am using Conquering the Physics GRE as an overview, but I really enjoy anything from David Morin and David J. Griffiths for the level of questions and explanations (and in-book/online solutions manuals that go a long way towards showing you how to think like a physicist). But my "library" for preparing for the physics GRE is:

CM: Morin, Problems and Solutions in Introductory Mechanics and Introduction to Classical Mechanics

Gregory, Classical Mechanics for extra explanations and problems

EM: Griffiths, Introduction to Electrodynamics 3e

QM: Griffiths, Introduction to Quantum Mechanics 3e

Thermo/Stat.Mech: Schroeder, An Introduction to Thermal Physics

Kittel and Kroemer, Thermal Physics

Waves: Morin, on his website are ten chapters to what appears to be a Waves book in the making

Atomic, Lab Methods: Conquering the Physics GRE and any online resources I can find.

Momentum is the value that the momentum operator gives you. It will be related to the time evolution of the field, as you would expect for a quantity classically related to velocity. In coherent states, which are mixtures of states in any bases that are sufficiently localized in space, the classical limit is recovered.


Spin is the result of another operator, but what it gives you is the angular momentum of an electron. Everybody agrees on this. No physicist thinks it's actually spinning because they're not dense and have enough imagination to know a vector quantity can exist all on its own. Here are two experts that agree on this definition - I know this because all the experts agree on the definition, because they're all working with the exact same mathematical model.

This is literally first year stuff, as in actual first years taking physics classes in college will learn it. Occasionally, they will delay it to their second year - I suppose that was my ego at play.
