rheology (ree-OL-oh-jee) - n., the study of the flow and deformation of matter.
This can be the flow of liquids, but also plastic matter and substances with a complex microstructure such as muds, sludges, suspensions, polymers, and glasses. Viscosity is everything to the rheologist. The Wikipedia article is fascinating, if you want to know more. Coined either in 1920 or 1929 (sources disagree) by American scientist Eugene C. Bingham, inspired by the aphorism πάντα ῥεῖ, everything flows, of Simplicius of Cilicia from Ancient Greek roots rhéō, flow + -logy, now understood as study of.
