History

Contributors in the Development of the Second Law:

• Nicholas Léonard Sadi Carnot (1 June 1796 – 24 August 1832)

  

  Nicholas Léonard Sadi Carnot

  • Considered to be the father of Thermodynamics
  • Major Scientific Contributions:
    • Carnot heat engine
    • Carnot theorem
    • Carnot efficiency
  • His research was centered around learning if the work available from a heat source was limited, and whether the efficiency of a heat engine could be improved upon by replacing steam with a different substance
• Rudolf Clausius ( 2 January 1822 – 24 August 1888)

  

  Rudolf Clausius

  • German Physicist
  • Developed the Clausius statement, which states that in general, heat can not flow spontaneously from a low temperature to a high temperature
  • Wrote a famous paper titled "On the Moving Force of Heat and the Laws of Heat which May be Deduced Therefrom"
    • Pointed out differences between the concept of conservation of energy
    • Stated that assumptions about the Caloric theory were incorrect
  • Presented the idea of Entropy and named it as such
  • Was known for taking a mathematical approach to physics
• William Thompson (26 June 1824 – 17 December 1907)

  

  William Thompson

  • Mathematical physicist and engineer
  • Formulated the Kelvin Statement, which states that there is no way to convert all of the energy in a given system into work without losing energy
  • Developed the vortex theory of the atom
• Constantin Carathéodory (13 September 1873 – 2 February 1950)

  

  Constantin Caratheodory

  • German mathematician of Greek origin
  • Principle of Caratheodory
  • Took on thermodynamics with a mathematical axiomatic foundation
  • Created his own version of the Second Law of Thermodynamics by stating that "In the neighborhood of any initial state, there are states which cannot be approached arbitrarily close through adiabatic changes of state."
