The second was the chapter in Roger Penrose’s book The Emperor’s New Mind in which he discusses entropy. He points out that there’s a sense in which it’s incorrect to say we eat food because we need the energy it contains. The conservation of energy means that it is neither created nor destroyed; we are radiating energy constantly, at pretty much the same rate that we absorb it. The difference is that the heat energy we radiate is a high-entropy form of energy, meaning it’s disordered. The chemical energy we absorb is a low-entropy form of energy, meaning it’s ordered. In effect, we are
