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
German resistance to Nazism sent from the German resistance were hardly satisfactory; for example in 1941 a proposal by Goerdeler demanded borders of 1914 with France, Belgium and Poland, as well as acceptance of annexation of Austria and Sudetenland. While German popular memory and public discourse portrays the resistance as isolated due to demand of unconditional surrender, in reality its isolation was due to unrealistic expectations of what the Allies would accept; while German commentators write that the resistance tried "to save that which remained to be saved", they omit the fact that it included a significant portion of territories conquered by Nazi Germany
