This man names a method of finding stress distributions of objects under torsion by solving the differential equation for the deflection of a soap film, his "membrane analogy." The thermal boundary layer thickness scales with the one-third power of a quantity named for this man. He is the alphabetically second namesake of a transformation used to solve the linearized potential equations for compressible, inviscid flow which features a singularity at the speed of sound. Because this man‟s number doesn‟t depend on length scale, the Peclet number is often dividedby the Reynolds number to give this number in dimensional analysis of forced convection, which yields the result that the Nusselt number is a function of the Reynolds number and this number. For 10 points, name this German physicist who introduced a region of fluid in which viscosity is significant, called the boundary layer.
