Exploratory Experiments: Ampčre, Faraday, and the Origins of Electrodynamics
University of Pittsburgh Press, 12. jún. 2016 - 544 síđur
The nineteenth century was a formative period for electromagnetism and electrodynamics. Hans Christian Řrsted’s groundbreaking discovery of the interaction between electricity and magnetism in 1820 inspired a wave of research, led to the science of electrodynamics, and resulted in the development of electromagnetic theory. Remarkably, in response, André-Marie Ampčre and Michael Faraday developed two incompatible, competing theories. Although their approaches and conceptual frameworks were fundamentally different, together their work launched a technological revolution—laying the foundation for our modern scientific understanding of electricity—and one of the most important debates in physics, between electrodynamic action-at-a-distance and field theories.
In this foundational study, Friedrich Steinle compares the influential work of Ampčre and Faraday to reveal the prominent role of exploratory experimentation in the development of science. While this exploratory phase was responsible for decisive conceptual innovations, it has yet to be examined in such great detail. Focusing on Ampčre’s and Faraday’s research practices, reconstructed from previously unknown archival materials, including laboratory notes, diaries, letters, and interactions with instrument makers, this book considers both the historic and epistemological basis of exploratory experimentation and its importance to scientific development.
