Beschreibung:
This book provides a chronological introduction to the electromagnetic theory of light, using selected extracts from classic texts such as Gilbert's De Magnete, Franklin's Experiments and Observations on Electricity, and Huygens' Treatise on Light. Particular attention is given to the works of Faraday, Maxwell and Heaviside, scientists who unified the formerly separate disciplines of electricity, magnetism and light. Their electromagnetic theory-developed during the 19th century-would lead to the invention of modern radar, electrical power grids, and telecommunication networks.
