In the second half of the nineteenth century, British firms and engineers built, laid, and ran a vast global network of submarine telegraph cables. For the first time, cities around the world were put into almost instantaneous contact, with profound effects on commerce, international affairs, and the dissemination of news. Science, too, was strongly affected, as cable telegraphy exposed electrical researchers to important new phenomena while also providing a new and vastly larger market for their expertise. By examining the deep ties that linked the cable industry to work in electrical physics in the nineteenth century - culminating in James Clerk Maxwell's formulation of his theory of the electromagnetic field - Bruce J. Hunt sheds new light both on the history of the Victorian British Empire and on the relationship between science and technology.

In the nineteenth century, science and technology developed a close and continuing relationship. The most important advancements in physics--the science of energy and the theory of the electromagnetic field--were deeply rooted in the new technologies of the steam engine, the telegraph, and electric power and light. Bruce J. Hunt here explores how the leading technologies of the industrial age helped reshape modern physics.

This period marked a watershed in how human beings exerted power over the world around them. Sweeping changes in manufacturing, transportation, and communications transformed the economy, society, and daily life in ways never before imagined. At the same time, physical scientists made great strides in the study of energy, atoms, and electromagnetism. Hunt shows how technology informed science and vice versa, examining the interaction between steam technology and the formulation of the laws of thermodynamics, for example, and that between telegraphy and the rise of electrical science.

Hunt's groundbreaking introduction to the history of physics points to the shift to atomic and quantum physics. It closes with a brief look at Albert Einstein's work at the Swiss patent office and the part it played in his formulation of relativity theory. Hunt translates his often-demanding material into engaging and accessible language suitable for undergraduate students of the history of science and technology.

James Clerk Maxwell published the Treatise on Electricity and Magnetism in 1873. At his death, six years later, his theory of the electromagnetic field was neither well understood nor widely accepted. By the mid-1890s, however, it was regarded as one of the most fundamental and fruitful of all physical theories. Bruce J. Hunt examines the joint work of a group of young British physicists—G. F. FitzGerald, Oliver Heaviside, and Oliver Lodge—along with a key German contributor, Heinrich Hertz. It was these "Maxwellians" who transformed the fertile but half-finished ideas presented in the Treatise into the concise and powerful system now known as "Maxwell's theory."
