Angular momentum in quantum mechanics

💻 Book a 1:1 session: https://docs.google.com/forms/d/e/1FA...

📚 Angular momentum is key in understanding many physical situations, perhaps most importantly the behaviour of particles moving in central potentials, like an electron in a hydrogen atom. In this video we upgrade classical angular momentum to a quantum mechanical operator, and we explore some of its properties. We also learn that angular momentum in quantum mechanics is not restricted to orbital angular momentum and introduce the idea of spin angular momentum, which has no classical analogue.
