Why do we call it the George Stokes Chamber?
George Gabriel Stokes, was an Irish mathematician and physicist. Born in County Sligo, Ireland, Stokes spent all of his career at the University of Cambridge, where he was the Lucasian Professor of Mathematics from 1849 until his death in 1903. As a physicist, Stokes made seminal contributions to fluid mechanics, including the Navier–Stokes equations; and to physical optics, with notable works on polarisation and fluorescence.
As a mathematician, he popularised “Stokes’ theorem” in vector calculus and contributed to the theory of asymptotic expansions. Stokes, along with Felix Hoppe-Seyler, first demonstrated the oxygen transport function of haemoglobin, and showed colour changes produced by the aeration of haemoglobin solutions.
Stokes’s work on fluid motion and viscosity led to his calculating the terminal velocity for a sphere falling in a viscous medium.
This became known as Stokes’ law. He derived an expression for the frictional force (also called drag force) exerted on spherical objects with very small Reynolds numbers.
