The collected papers of Sir George Stokes, the outstanding and influential nineteenth-century Cambridge mathematician.Sir George Stokes established the science of hydrodynamics with his law of viscosity describing the velocity of a small sphere through a viscous fluid. He published no books, and these collected papers (issued between 1880 and 1905) constitute the main surviving record of the work of this outstanding mathematician.Sir George Stokes established the science of hydrodynamics with his law of viscosity describing the velocity of a small sphere through a viscous fluid.

He published no books, but was a prolific lecturer and writer of papers for the Royal Society, the British Association for the Advancement of Science, the Victoria Institute and other mathematical and scientific institutions. These collected papers (issued between 1880 and 1905) are therefore the only readily available record of the work of an outstanding and influential mathematician, who was Lucasian Professor of Mathematics in Cambridge for over fifty years, Master of Pembroke College, President of the Royal Society (18851890), Associate Secretary of the Royal Commission on the University of Cambridge and a Member of Parliament for the University.Obituary notice by Lord Rayleigh; 1.
