MSN Usually, we think of electrons as more materialistic than photons, because they at least have a little rest mass, but Dirac Electrons don't have rest mass, and now they've been discovered as naturally occurring in at least one material. You could say, they're proof that without photons, ya got nothing kid! While, without electrons, ya might as well have nothing! And, nothing from nothing ain't nothing! They're proof that photons and electrons form a self-organizing system, that can be up to 125% efficient. And, should obey a well known multifractal equation, explaining all of their other distinctive behaviors as expressing particle-wave duality over larger and smaller scales and magnitudes, according to the specific context.
