  • The energy of work
    • Energy and industry:  Mechanisation, growth of the city, EFFICIENCY major industrial drive
    • Factories
      • Ideological representation: 1) 'Minding', no labour required 2) Order and reason, no chaos 3) Master in control. This is PROJECTION of what want it to look like.
        • Humans as machines
        • System of ORDER and RATIONALITY. Linked with social order.
    • Energy and the French - Sadi Carnot
      • 'To take away from England her steam engines would be to dry up all her sources of wealth, to ruin everything on whch her prosperity depends' - NATIONAL RIVALRIES
      • 1824 'Reflexions': EFFICIENCY! Managerial concerns. Heat is CONSERVED.
    • Energy and the Germans
      • Work on ENERGY mostly done as analysis of HUMAN LABOUR. Helmholtz had a medical background - dietetics, how to extract work from food (physiological model)
        • James Joule - opposite to German physiological model - human behaviour modelled on machines.
          • National style of science influenced by the way that industry was set up (Germany vs Britain)
    • Energy and the Brits - James Joule
      • James Joule - opposite to German physiological model - human behaviour modelled on machines.
        • National style of science influenced by the way that industry was set up (Germany vs Britain)
      • Work is performed when heat is converted into work. Heat and work TOGETHER are conserved, but HEAT IS CONSUMED. Paradox with Joule
      • Industry influencing science: Britain experiencing displacement of COAL by ELECTRICITY - how to compare profit of different systems!
    • William Thomson resolves paradox between Joule and Carnot
      • Heat and work are mutually convertible at a fixed rate (Joule)
      • Universal tendency towards dissipation and loss of available work
        • People at the time thought this was depressing. Links with DEGENERATION
