Friction friction and wear in so-called self-lubricating materials. Fluid friction occurs between fluid layers that are moving relative to each other. This internal resistance to flow is named "viscosity". In everyday terms, the viscosity of a fluid is described as its "thickness". Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. The less viscous the fluid, the greater its ease of deformation or movement. All real fluids (except superfluids) offer some resistance to shearing and therefore are viscous. For teaching and explanatory purposes it is helpful to use the concept of an inviscid fluid

In "The International Journal of Humanities & Peace", Carol Burke wrote that "God Makes the Rivers to Flow" (2003) contains "rich resources" that offer "much to satisfy even the most restless mind." In addition to the "vast assortment of inspiring passages," the section on using passages for specific purposes is "practical," the biographical notes are "interesting," and the introduction "entertainingly encourages" readers to begin personal transformation. Burke states that many passage sources will be familiar, but "many other passages perhaps less familiar, from Hinduism,
