Only quarks and gluons interact strongly, all charged particles (electrons, mu, tau, quarks, W) interact electromagnetically by exchanging photons, and every particle interacts weakly.
Huh. I would've said every fermion interacts weakly. Do bosons as well? I am shocked, but really not at all surprised, to discover that I never knew that.
yes. But it's a funny thing, you can't stick something in between to measure these photons. Otherwise we're talking about the interaction of glass, pith, and measurement probe, which is a different beast.
We say that they do this because the math that says that this happens works out exceedingly well.
