DESCRIPTION:Thermodynamics centres on the fact that work and heat are not 
 functions of state yet the natural formalism to capture this fact was deni
 ed to thermodynamics by its historical pre-dating of vector field notation
 .  One reason for re-examining this omission is provided by the work of Sa
 di Carnot who initiated thermodynamics.  His results\, which he derived fr
 om his grand principle\, were not obtained by what is now called the secon
 d law of thermodynamics or by the first law of thermodynamics.  His result
 s were obtained a (co)vector formula\, albeit expressed in words not symbo
 ls.  Carnots formula allowed him to obtain several standard results of the
 rmodynamics\, including the Clausius-Clapeyron equation.  The formula also
  implies the Maxwell relations.
