The binding is transfer of photons afaik at present. = Even sound is ultimately transmitted via photons. Electrons transmit photons. They "eat them" and "spit them out". I think of basketball players (electrons) moving slowly passing basketballs quickly (photons) Electrons afaik ACTUALLY don't move very quickly at all. It's the photons they pass that do. == Sound is still pretty amazing to me. Waves blow my mind far more than particles do - how it all works together like that. Love it. == Skipping the photon stuff for a second, I was thinking of the functioning of a computer and semiconductors and information. The speed of electrons is about that of maple syrup or molasses. Electricity works more like sound. It's waves of stuff that's already there. It's why I hate the terminology different places use - and I REALLY hate the way they teach "electricity" in schools. Takes years to unravel, if at all, once they teach it wrong. == Yes, exactly. It's funny... even though I *know* intuitively how it works now, I _still_ get those ancient school lessons getting in the way. It's annoying :) ==
