Understanding Rheology: The Philosophy of Flow and Deformation

The Society of Rheology embraces the phrase "panta rei," attributed to Greek philosopher Heraclitus, meaning "everything flows." This motto, suggested by Eugene Cook Bingham, reflects the essence of rheology as the study of deformation and flow of materials. Rheology is fundamental in understanding various fluids, including non-Newtonian fluids that exhibit dynamic behaviors under stress. We explore concepts such as viscosity, polymer interactions, and their applications in everyday life from educational resources and engaging demonstrations.

  1. Capital University Rheology

  2. The Greek letters on the hourglass logo of The Society of Rheology— panta rei (sometimes pronounced “ panta rei”)—may be translated “everything flows.” This phrase (or philosophy) is attributed to the Greek philosopher Heraclitus of Ephesus (536–470 BCE) and is taken from the more complete quote: “Everything flows and nothing abides; everything gives way and nothing stays fixed.” The Society motto was suggested by Eugene Cook Bingham and it reflects the field of study of rheology — deformation and flow.
