Waves & Whirlpools: on Energy, Structure, Matter, & Antimatter (Part IV)

With the first parts of this series (read part I, part II, and part III), we've built up the idea that the electric charge of a particle is very closely analogous to the angular momentum of an eddy in a fluid. Alike-spinning whirlpools repel, while opposite-spinning ones attract and, when they meet, annihilate one another--with the energy they contained radiating away as waves, just like matter and antimatter. But the surface of a pond is only two-dimensional, so to find out just how far this an...
