Why Is It So? - Season 2 Episode 3 Episodul 3 (2012)
Professor Miller rattles off several types of energy, and adds that heat energy is a degenerate form. Whenever work is done, heat is a by-product. Thus Miller takes a nail out with a hammer, pumps a bicycle pump, slides a string around the neck of a perfume bottle and bends a paper clip to generate small amounts of heat.
