He was Beyer professor of applied mathematics, Victoria University of Manchester, 1924-28, before his appointment to the Rouse Ball chair of mathematics and to a fellowship at Wadham College, Oxford, in 1928. Milne's earlier work was in mathematical astrophysics, for which he was awarded the Royal Astronomical society's gold medal in 1935. From 1932 he also worked on the problem of the "expanding universe" and in Relativity, Gravitation, and World-Structure (1935), proposed an alternative to Albert Einstein's general relativity theory. His later work, concerned with the interior structure of stars, aroused controversy.
