4:21Now PlayingIn our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's why it's called quantum theory, we are showing how particles, or quanta, run the whole show. The electromagnetic force was the first one to get a facelift, so let's check out how these quantum field theories work by looking at quantum electrodynamics!
