Stokes, George Gabriel (1819–1903)
George Stokes was a British mathematician and physicist, born in Ireland. He was professor of mathematics (1849–1903) at Cambridge and served as president (1885–92) of the Royal Society. Stokes is celebrated for his law of viscosity (Stokes's law), which describes the movement of a solid sphere in a fluid. It forms the basis of the modern theory of viscous fluids. He also developed an important theorem of vector analysis, accurately described and named fluorescence, and proposed the concept of an ether. Stokes' book, Dynamic Theory of Diffraction (1849) was an important work in the wave theory of light. He was a pioneer of geodesy.
