Inviscid flow Inviscid flow Inviscid flow is the flow of an inviscid fluid, in which the viscosity of the fluid is equal to zero. Though there are limited examples of inviscid fluids, known as superfluids, inviscid flow has many applications in fluid dynamics. The Reynolds number of inviscid flow approaches infinity as the viscosity approaches zero. When viscous forces are neglected, such as the case of inviscid flow, the Navier-Stokes equation can be simplified to a form known as the Euler equation. This simplified equation is applicable to inviscid flow as well as flow with low viscosity and a Reynolds number much
German resistance to Nazism Lieutenant Heinrich Graf von Lehndorff-Steinort: “The assassination must be attempted, "coûte que coûte" [whatever the cost]. Even if it fails, we must take action in Berlin. For the practical purpose no longer matters; what matters now is that the German resistance movement must take the plunge before the eyes of the world and of history. Compared to that, nothing else matters.” In retrospect it is surprising that these months of plotting by the resistance groups in the Army and the state apparatus, in which dozens of people were involved and of which many more, including very senior Army officers, were
