Matter & Interactions II, Weeks 13 and 14

I’m combining two weeks in this post. The first week, we dealt with magnetic forces. One thing that I have never thought much about is the fact that the quantity is effectively an electric field, but one that depends on velocity. When velocity is involved, reference frames are involved, and that of course means Einstein […]
