|Stokes, Sir George Gabriel 1819-1903.
Irish mathematician and physicist who investigated the wave theory of light and described the phenomena of diffraction (1849) and fluorescence (1852) and the nature of x-rays. He also investigated fluid dynamics, developing the modern theory of motion of viscous fluids. A unit of kinematic viscosity is named for him.
