An example of an analogy used to explain a principle in a popular science book:
"The idea that the same amount of heat causes a greater change of entropy in a cold place than a hot one can seem strange. But consider this as an analogy: A noisy, crowded pub is next to a a quiet library. Five rowdy people leave the pub. The din drops but by an indiscernible amount. The five stumble into the library. The noisiness there increases noticeably. When a group of raucous people enter a quiet place, the increase in disruption there is much greater than its fall in the boisterous place form which they came.
Similarly, when a quantity of heat flows out of a hot room, the fall in entropy there is smaller than the increase that occurs when the heat enters a cold room."
