I used to think electrons flow through circuits, then I learned they actually move extremely slowly, so when you flip a switch there is no way an electron made it all the way to the lamp and back. So now I assume the energy of an electron is transferred to the rest through the electromagnetic field in the circuit or something like that? Honestly, I don't have the slightest idea how any of this works and what is true and what is false anymore. It's not really relevant to computers and yet it's all very fascinating.
