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 ...

I'm teaching introductory Newtonian mechanics again this term, and as always I find myself fascinated by bits of the subject that my students are largely indifferent to. This week, that collided with ...

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 ...

The uncertainty principle states that we cannot know the state of a system with arbitrary precision. Now the uncertainty relation between angular momentum and position has been measured in an ...
