rheometryn.

Brit.

/rɪˈɒmᵻtri/, U.S.

/riˈɑmətri/

Origin: Formed within English, by compounding. Etymons: rheo- comb. form, -metry comb. form.

Etymology: < rheo- comb. form + -metry comb. form. In senses 2 and 3 after rheometer n.

†1. Mathematics. The Newtonian calculus. Cf. fluxion n. 5. Obsolete. rare.

rheometry1841

1841 R. Park Pantology ix. v. 337 For this branch of Mathematics, we venture to propose the name Rheometry; from the Greek ῥεω, I flow, suggested by the name Fluxions, applied to this science by Newton.
