He's not Cauchy, but this scientist is the first alphabetical namesake of a pair of stress tensors, one of which is the transpose of the nominal stress tensor.
With A. E. H. Love, this scientist names a two-dimensional extension of Euler-Bernoulli beam theory. This scientist also names a set of equations for calculating the hydrodynamic torque and force of a rigid body in an ideal fluid. He's not Cauchy, but this scientist is the first alphabetical namesake of a pair of stress tensors, one of which is the transpose of the nominal stress tensor. A theorem named for this scientist relates the (*) emissivity and absorptivity of a body in thermal equilibrium. One law created by this scientist states that the sum of currents flowing into a node must equal the current flowing out of the node, and that law is frequently paired with his "loop rule". For 10 points, name this German scientist who also coined the term "black body radiation".
