Rheology - main page Rheology Introduction Rheology is the science of flow and deformation of matter and describes the interrelation between force, deformation and time. The term comes from Greek rheos meaning to flow.
Rheology is applicable to all materials, from gases to solids.
The science of rheology is only about 70 years of age. It was founded by two scientists meeting in the late '20s and finding out having the same need for describing fluid flow properties. The scientists were Professor Marcus Reiner and Professor Eugene Bingham. The Greek philosopher Heraclitus described rheology as panta rei - everything flows . Translated into rheological terms by Marcus Reiner this means everything will flow if you just wait long enough.
