Oliver Heaviside (1850-1925), the self-taught physicist and electrical engineer, began his career as an operator on the newly laid Anglo-Danish telegraph cable in 1868. The most advanced electrical technology of the time, the cable system inspired several of his early mathematical papers. This monograph, first published as a paper in the Philosophical Magazine in 1888, then as a book in 1889, draws on his established work on telegraphic propagation and self-inductance, and on Maxwell's field theory. In a fascinating insight into the contemporary scientific community, he complains that these...
