John Tresch’s beautiful new book charts a series of transformations that collectively ushered in a new cosmology in the Paris of the early-mid nineteenth century. The Romantic Machine: Utopian Science and Technology after Napoleon  (University of Chicago Press, 2012) narrates the emergence of a new image of the machine, a new concept of nature, a new theory of knowledge, and a new political orientation through a series of chapters that each use the work of a single figure to open up a world of romantic machines.
