Spin, Angular Momentum, Momentum, Energy & NRQM

In summary, spin is a quantum property of particles that describes their intrinsic angular momentum and differs from classical angular momentum. Momentum and energy are fundamental quantities in physics, with their relationship given by E = p^2/2m in classical mechanics. The uncertainty principle states that it is impossible to know both momentum and position of a particle simultaneously, and this is a fundamental principle in quantum mechanics. Spin is incorporated into the non-relativistic quantum mechanics framework through the wavefunction and Hamiltonian, allowing for the description and calculation of spin-dependent properties. The conservation of angular momentum is a fundamental law in physics and is also conserved in quantum mechanics, with discrete values due to quantization.

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.

Spin is part of angular momentum.
