An example of an analogy used by a scientist:
"By this formulation one reduced the whole mechanics of gravitation to the solution of a single system of covariant partial differential equations. … But it is similar to a building, one wing of which is made of fine marble (left part of the equation), but the other wing of which is built of low-grade wood (right side of equation)."
