Electrodynamics from Ampère to Einstein (Broché)

Three quarters of a century elapsed between Ampère's definition of electrodynamics and Einstein's reform of the concepts of space and time. The two events occurred in utterly different worlds: the French Academy of Sciences of the 1820s seems very remote from the Bern patent Office of the early 1900s, and the forces between two electric currents quite foreign to the optical synchronization of clocks. Yet Ampère's electrodynamics and Einstein's relativity are firmly connected through a historical chain involving German extensions of Ampère's work, competition with British field conceptions, Dutch synthesis, and fin de siècle cristicim of the aether-matter connection. Olivier Darrigol retraces this intriguing evolution, with a physicist's attention to conceptual and instrumental developments, and with a historian's awareness of their cultural and material embeddings. This book exploits a wide range of sources, and incorporates the many important insights of other scholars. Thorough accounts are given of crucial episodes such as Faraday's redefinition of charge and current, the genesis of Maxwell field equations, and Hertz, experiments on fart - electric oscillations. Thus there emerges a vivid picture of the intellectual and instrumental variety of nineteenth-century physics. The most influential investigators worked at the crossroads between different disciplines and traditions: they did not separate theory from experiment, they frequently drew on competing traditions, and their scientific interests extended beyond physics into chemistry, mathematics, physiology and other areas. By bringing out there important features, this book offers a tightly connected and yet sharply contrasted view of early electrodynamics. This book won the Marc-Auguste Pictet prize of the Société de physique et d'Histoire Naturelle de Genève for the year 2000.
