James Prescott Joule, William Thomson, and the mechanical equivalent of heat.
James Prescott Joule, a Manchester owner of a brewery stood in the lecture hall and looked into the faces of the audience that was going to listen to his talk. It was the annual meeting of the British Association for the Advancement of Sciences, the conference where most scientists presented their latest achievements. However, Joule felt a bit uncomfortable, as he was not a trained scientist and considered himself a bit as an outsider. Moreover, it seemed to him that the audience was not really waiting for him to start, but seemingly more eager for him to stop. He seemed to see disinterest in most of the faces that were looking at him. Before starting his communication, Joule took a deep breath and thought about what had him brought here. ...
