Document Summary
Industrial revolution was trying to exploit the forces of nature to power machinery, looking at machinery and not to produce motive force. Carnot, his son sadi, productive motive force, focused of the steam engine following the movements of caloric through the engine, steam was only a way of transporting caloric, caloric was conserved. Oersted, interested in natural philosophy, universe should be regarded as a single organic cosmic entity, convinced there was a link between electricity and magnetism. Ampere, surrent-carrying wire that is a helix acts as a regular magnet. Seebeck, examine connections between electricity, magnetism and heat, produce magnetic phenomena by heat, a circuit of copper and bismuth where the metals joined, a current registered. Grove, correlation of physical forces, no one force could be shown to cause another because they are all mutually correlative, Mayer, heat of tropics bore correlation to oxygenation of blood, heat is motion, calculated fall of specific weight for the heating of 1 c.
