Seeing Foucault''s Pendulum - Seeing the Earth Move Michael Hagner

An investigation of a cosmic experimentIn 1851, the physicist Léon Foucault performed an unforgettable experiment. By suspending a large pendulum inside the dome of Paris’ Pantheon, Foucault provided the first simple, direct empirical evidence of the Earth''s rotation—an undeniable demonstration of heliocentrism. This experiment, conducted long after the Copernican Revolution and using a laboratory apparatus rather than astronomical observation, visually confirmed what had previously been accepted as theory. The pendulum’s motion clearly illustrated the Earth''s rotation. But Foucault’s experiment did not end there. It sparked a range of subsequent reenactments and interpretations, each adding new layers to its meaning. Repeated over and again, its afterlives were many as were its ramifications.Historian Michael Hagner revisits this epoch-making experiment and its reception from the nineteenth century to the present day and follows how cosmological questions conjoined political and aesthetic judgments about the public staging and history of science. The pendulum experiment, Hagner argues, is more than just a mere scientific demonstration. It contains within it the histories of technological innovation, ideological conflicts, and the rise of popular culture and visual media. In a series of insightful studies of literary, artistic, and scientific reenactments, Hagner uses both words and images to narrate the rich and complex legacy of this experiment.Seeing Foucault'
