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 ...

Observing the effects of special relativity doesn't necessarily require objects moving at a significant fraction of the speed ...

A group of physicists has claimed that a key motivation for the many worlds interpretation of quantum mechanics is unnecessary. They seem to think that the many worlds interp ...

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 ...
