Sadi Carnot Against the Second Law of Thermodynamics

In 1824 Sadi Carnot deduced the prototype of the second law of thermodynamics from a postulate that eventually turned out to be false:

Carnot's (false) postulate: Heat is an indestructible substance (caloric) that cannot be converted into work by the heat engine.

Consequence (prototype of the second law of thermodynamics) : As the heat engine produces work, A COLD BODY IS NECESSARY.

That is, since the heat is not...


"Entropy always increases" is another nonsensical mantra in today's schizophrenic science. This statement (which, according to A. Eddington, holds "the supreme position among the laws of Nature") is in fact a theorem deduced by Clausius in 1865:

Jos Uffink, Bluff your Way in the Second Law of Thermodynamics, p. 37: "Hence we obtain: THE ENTROPY PRINCIPLE (Clausius' version) For every nicht umkehrbar [irreversible] process in an adiabatically isolated system which begins and ends in an...
