Formed from Ancient Greek ῥέω (rhéō, “flow”) +‎ -logy (“study of”, suffix ultimately from Ancient Greek). See also rheo-.

   • 2022 April 19, Jennifer Chu, “MIT Engineers Introduce the Oreometer”, in MIT News‎^[1]:

     Curious as to whether other had explored the connection between Oreos and rheology, Owens found mention of a 2016 Princeton University study in which physicists first reported that indeed, when twisting Oreos by hand, the cream almost always came off on one wafer.
