In 1885, (at the age of 23), Bragg was appointed Elder Professor of Mathematics and Experimental Physics at the University of Adelaide, and started work there early in 1886. Being a skilled mathematician, at that time he had limited knowledge of physics, most of which was in the form of applied mathematics he had
