    Generators Spin
Click For Summary
Angular momentum is fundamentally linked to rotations, while momentum pertains to spatial translations and energy to temporal translations. Spin is a specific type of angular momentum associated with quantum particles. In non-relativistic quantum mechanics (NRQM), spin plays a crucial role in defining the behavior of particles. Understanding these relationships is essential for grasping the principles of NRQM. Spin is indeed related to angular momentum and is a key concept in quantum mechanics.

Angular momentum is related to rotations.
Momentum is related to spatial translations.
Energy is related to temporal translations.
Is spin related to anything?
I only know the introduction to NRQM from Griffiths' book.

Thread 'One does not “prove” the basic principles of Quantum Mechanics'

I am slowly going through the book 'What Is a Quantum Field Theory?' by Michel Talagrand. I came across the following quote: One does not" prove” the basic principles of Quantum Mechanics. The ultimate test for a model is the agreement of its predictions with experiments. Although it may seem trite, it does fit in with my modelling view of QM. The more I think about it, the more I believe it could be saying something quite profound. For example, precisely what is the justification of...
