Townsend became the first person to measure the elementary ionic charge. For most of his career, he worked at Oxford as the Chair of Experimental Physics. Up until the First World War, Townsend was a leader in his field of research. He was responsible for the theory of 1900 that ionization occurred as a result of the collision between electrons and the molecules of gases. Townsend's theory was used in 1908 to create the famous Rutherford–Geiger counter for detecting alpha particles. A nice copy of the book containing Townsend’s most important results. Near Fine.

A small scuff to the front board and one tiny tear to the gutter of the title page, overall a pleasing copy.
