An example of an analogy used in explaining science:
"The first impact against the very foundations of the beautiful and, apparently eternal, castle of classical physics, an impact that shook practically every single stone of this elaborate building and sent its walls tumbling down, like the walls of Jericho before the blast of Joshua's trumpet, was delivered by what would seem to be an unpretentious experiment carried out in 1887 by an American physicist, A. A. Michelson. The idea of Michelson's experiment is very simple and is based on a physical picture according to which light represents some kind of wave motion travelling through the so called 'light-carrying ether', a hypothetical substance uniformly filling up interstellar space as well as the intervals between the atoms in all material bodies."
