Stokes, Sir George Gabriel

Sir George Gabriel Stokes, 1819–1903, British mathematician and physicist, b. Ireland, studied at Cambridge. From 1849 he was a professor of mathematics at Cambridge; he served as secretary (1854–85) and as president (1885–92) of the Royal Society. His researches, done in many fields, developed the modern theory of viscous fluids, revealed the nature of fluorescence, and helped to establish the composition of chlorophyll. The important work he did on the undulatory theory of light led to publication of his Dynamical Theory of Diffraction (1849). His other publications include Light (1884) and Natural Theology (1891).

Stokess law

Stokes's law A law describing the rate at which suspended particles settle, formulated in 1845 by the physicist Sir George Gabriel Stokes (1819–1903). The settling velocity (V) in cm/s is calculated by V = CD2, where C is a constant related to the density and viscosity of the fluid and the density of the suspension and D is the diameter of the particles (assumed to be spheres) in cm.
