M AXWELL is universally accepted as the greatest heoretical physicist of the nineteenth century. In the words of Max Planck, the senior leader of twentieth-century theoretical physics, "it was his task to build and complete the classical theory, and in doing so he achieved greatness unequalled. His name stands magnificently over the portal of classical physics, and we can say this of him: by his birth, James Clerk Maxwell belongs to Edinburgh, by his personality he belongs to Cambridge, by his work he belongs to the whole world."
