In Maxwell's Demon: Why Warmth Disperses and Time Passes, physics professor Hans Christian von Baeyer tells the story of heat through the lives of the scientists who discovered it, most notably James Clerk Maxwell, whose demonic invention has bedeviled generations of physics students with its light-fingered attempts to flout the laws of thermodynamics. An intelligent, submicroscopic gremlin who could sort atoms as they flew at him, Maxwell's Demon would effectively make an impossible task - forcing heat to flow backward - possible. Explaining why the Demon can't have his day has been an…
