Convened by Robert Fox (University of Oxford)

In his Réflexions sur la puissance motrice du feu, a modest volume published in 1824, Sadi Carnot laid some of the most important foundations of modern thermodynamics and power technology. In certain respects, the book was not an easy read, and it had faults. The result was a masterpiece, though arguably a flawed one, and it remained almost unread until it was discovered and reconfigured by William Thomson (the future Lord Kelvin) and Rudolf Clausius from the late 1840s. Given the importance that physical scientists and engineers now attach to such fundamental ideas as the Carnot cycle, the second principle of thermodynamics, and the notion of entropy – all of which have roots in Carnot’s thinking – why was the Réflexions neglected for so long? The contributions to this workshop explore the origins, content, and long-term impact of Carnot’s ideas, including the legacy of debates about energy sources and implications for climate change that continue to engage us today.
