This man is the namesake of equations which contain terms for Ricci Tensor 
This man is the namesake of equations which contain terms for Ricci Tensor and the stress-energy tensor. Along with Podolsky and Rosen, he names a paradox that was solved by assuming locality with Bell's theorem, and he is also the namesake of a mole of photons. He used the kinetic theory of gases to explain a phenomenon observed by a Scottish botanist Robert Brown. For 10 points, identify this scientist who won the 1921 Nobel Prize in Physics for his work on the photoelectric effect.
