This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

This statement is a crucial underpinning of physical laws, from those that govern the rotation ... momentum. The symmetry of moving around in a circle amounts to the law of conservation of angular ...

This expansion is most noticeable on the largest cosmic scales. Angular momentum is crucial to cosmic rotation. When two objects in space come close together, their mutual gravity pulls them ...
