It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...

Many people don't know too much about angular momentum—and that's fine. But what about figure skaters? Whether they understand the concept of angular momentum doesn't matter but they use it in one of ...

a) In a weak magnetic field, broad cyclotron orbits suppress the orbital contribution, allowing spin polarization to dominate, (b) In strong magnetic fields, tight cyclotron orbits enhance orbital ...

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 ...

We live and die by data these days. Data rates and latencies are everything, with data centers and chips designed to maximize communication speeds. The hero in the world of data is the optical fiber.
