Etymology
Coined by American scientist Eugene C. Bingham in 1920, following a suggestion by a colleague, Markus Reiner; inspired by aphorism πάντα ῥεῖ (pánta rheî, “everything flows”) by Simplicius of Cilicia. Formed from Ancient Greek ῥέω (rhéō, “flow”) + -logy (“study of”, suffix ultimately from Ancient Greek). See also rheo-.
