How much can you build out of the very simplest building particle, just electrons? You can have a positive electron and a negative electron going around each other, on this picture I was talking about a moment ago. It's an electron that goes forward in time and turns around, comes backward in time, and these two, before they get up there, have a corkscrew. But any rate, not only can you have one positive and one negative electron; you can have two positives, two negatives, and one positive, and more and more. I call these polyelectrons. So far, the most anybody has been able to go in making these things is two positrons and two electrons together. A short lived object, but it lives long enough so that it can be compared sensibly with a molecule. And I call these things polyelectrons as a way to give a shorthand description of what we're talking about. Fun objects, they don't prove anything very much except that if you compare your predictions with experiment, you can say, well, I must know enough to predict.
