• It started billions of years ago, when big leafy plants covered the Earth, and dinosaurs ruled. They died off, and over many eons decayed in an anaerobic environment, got compressed and shit, and eventually became crude oil. Many, many homework assignments later, they got rudely pumped to the surface, mostly by folks who never got to college because they had others doing their homework for them. The oil was loaded onto ships and pumped through pipelines to refineries, where it was separated into different kinds of pollutants. Some of that fuel -- typically diesel fuel or kerosene, was shipped off to be burned up in huge turbines connected by a shaft to electric generators, which produced electricity in exchange for emitting air pollutants to be breathed by people who don't do their own homework. The electricity flowed out of the generator in big wires, through transformers and shit, and finally into the house that had the light bulb. The electrons rushed in through the circuit breakers and junction boxes, and some of it went off to the living room where the kids were sitting around watching Lost instead of doing their own homework. Other electrons rushed over to the light bulb, which was left on by a kid who almost never does his own homework. They pushed up through the bottom electrode of the bulb, and into the filament -- a thin wire that RESISTS the flow of electricity a bit, much like some kids resist doing their homework. Because of this resistance, the wire got hot, and glowed, producing light... the same kind of light that can be used to do one's homework by. Then the electrons flowed out the other electrode, back into the wiring, out through the circuit breaker panel, back up onto the power pole, and finally back to the generator, which was glad to have them. Moral of the story: do your own homework.
