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
The Resistance to Theory The Resistance to Theory "The Resistance to Theory" is an essay by Paul de Man (1919–83), a renowned literary critic and theorist belonging to the Yale School of Deconstruction, which appeared in "Yale French Studies" 63 (1982) and was widely anthologized. The essay later became part of the book by the same name. The essay remains a key statement in poststructuralist approaches to literary studies. Paul de Man says that the essay was written at the request of the Committee on the Research Activities of the Modern Language Association as a contribution to a collective volume entitled "Introduction to Scholarship
