What do we mean 物质? What fundamental particles do we know up to now? Say electron, positron, photon, muon, neutrino, and so on.www.ddhw.com photons are the quanta responsible for electromagnetic interaction W+, W-, Z are responsible for weak interaction, etc Do you have to distinguish static electric field and dynamic electromagnetic field? At last, Is static magnetic (electric) field really a true field, or simply a conveniet term? If it is really a field, what's the quanta for it? www.ddhw.com
