Caloric Theory -- from Eric Weisstein's World of Physics

The theory that heat consisted of a fluid (called caloric), which could be transferred from one body to another, but not "created" or "destroyed." The theory was refuted by Rumford, Eric Weisstein's World of Biography Joule, Eric Weisstein's World of Biography Mayer, Eric Weisstein's World of Biography Clausius Eric Weisstein's World of Biography, and others. Rumford Eric Weisstein's World of Biography was among the first to show that work could be converted to heat during the process of boring cannons, but his results were largely ignored.
