Erste Ausgabe. - Joule began work about 1845 on a fourth method for determining the mechanical value of heat. His latest efforts received a polite but unremarkable reception at the Cambridge meeting of the British Association. This time the experiments involved a paddle wheel placed in a can filled with water. Weights attached over pulleys working in opposite directions communicated motion to the paddle wheel. Joule argued that the force spent in revolving the paddle wheel produced a certain increment in the temperature of the water..." (DNB). - Tafel etw. stockfleckig. - Exlibris. - (1499)
