Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. I'm teaching introductory Newtonian mechanics again this term, and as ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...

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 ...

Yes. I just posted about MythBusters. However, I thought this would be an appropriate time to also talk about the physics involved with the "shoot the merry go round" myth. The basic idea of the myth ...

Topological insulators do not allow conduction in the bulk, yet they support edge modes that travel along the boundary only in one direction, determined by the carried electron spin, with inherent ...
