An example of metaphor drawn from science:
"We do well to be skeptical of a grammarian's systemization when it is full of ENANTIOMORPHISM, the pairing with every category of an opposite which is merely the lack of it."
Benjamin Lee Whorf
Whorf, B. L. (1945/2012). Grammatical categories. In J. B. Caroll, S. C. Levinson, & P. Lee (Eds.), Language, Thought, and Reality (2nd ed., pp. 113-130). The MIT Press.
Whorf, famous as a linguist, but with a background in chemical engineering uses a metaphor referring to a concept from crystallography to make a point about language theories.
