In simplest terms, viscosity is defined as “the resistance to flow” and is often referred to as the thickness of a fluid. The concept of a fluid having a “thickness” has existed for thousands of years, however the term “viscosity” was not introduced until 1929. Even Newton referred to viscosity as “the lack of slipperiness of the parts of the liquid” (Sir Isaac Newton, Principia, 1687).
