Sadi Carnot (Paris, June 1 1796 - Paris, August 24 1832) was a French mathematician who wrote on the principles of the second law of thermodynamics in his treatise on heat engines (Carnot cycle).
Sadi Carnot, a son of the eminent geometer Lazare Nicholas Marguerite Carnot, was the most eminent of Fourier's contemporaries who were interested in the theory of heat.
Sadi Carnot was born at Paris, France, in 1796, and died there of cholera in 1832; he was an officer in the French army.

 Nicolas Léonard Sadi Carnot - Wikipedia, the free encyclopedia
Nicolas Léonard Sadi Carnot (June 1, 1796 - August 24, 1832) was a French mathematician who gave the first successful theoretical account of heat engines, the Carnot cycle, and laid the foundations of the second law of thermodynamics.
Born Paris, Sadi Carnot was the son of the eminent geometer Lazare Nicholas Marguerite Carnot and brother of Hippolyte Carnot.
Perhaps the most important contribution Carnot made to thermodynamics was the process of abstraction of the essential features of the steam engine as it was known in his day into a more general, idealized heat engine.

When early in 1889, Boulanger was finally driven into exile, it fell to Carnot to appear as head of the state on two occasions of special interest, the celebration of the centenary of the French Revolution in 1889 and the opening of the Paris Exhibition of the same year.
Carnot was reaching the zenith of popularity, when, on June 24, 1894, after delivering at a public banquet at Lyon a speech in which he appeared to imply that he nevertheless would not seek re-election, he was stabbed by an Italian anarchist named Sante Jeronimo Caserio and died almost immediately.
The stabbing aroused widespread horror and grief, and the president was honoured with an elaborate funeral ceremony in the Panthéon, Paris.

Sadi Carnot was the eldest son of Lazare Carnot and he was born in the Palais du Petit-Luxembourg.
Sadi Carnot was born at a time of unrest and political turmoil in France and, due the position of his father, whose fortunes changed dramatically many times, he was brought up in a totally unstable environment of interacting politics and science.
Carnot's father was appointed minister of the interior and Sadi Carnot was put in a somewhat difficult position in the military academy with his father in such a prominent position.

His first work, published in 1784, was on machines; it contains a statement which foreshadows the principle of energy as applied to a falling weight, and the earliest proof of the fact that kinetic energy is lost in the collision of imperfectly elastic bodies.
His son Sadi Carnot was responsible for the second law of thermodynamics.
His grandson Marie François Sadi Carnot (son of Hyppolyte) was President of France from 1887 until his assassination in 1894.

Carnot ainda hesitou entre o conceito de calor como fluido material e a noção de calor como resultado de movimentos moleculares.
Carnot demonstrou que o funcionamento de toda máquina térmica supõe uma fonte quente e uma fonte fria; há então o transporte de uma quantidade de calor da primeira para a segunda.
Carnot, depois de realizar uma análise cuidadosa do funcionamento do motor térmico, construiu uma máquina que, trabalhando com gás aquecido ou resfriado, servia para medir a quantidade de energia mecânica produzida; permitia também calcular a porcentagem de energia térmica transformada em mecânica.

Nicolas LEonard Sadi Carnot[nEkOlA´ lAOnAr´ sAdE´ kArnO´] Pronunciation Key, 1796–1832, French physicist, a founder of modern thermodynamics; son of Lazare N. Carnot.
Carnot devised an ideal engine in which a gas is allowed to expand to do work, absorbing heat in the process, and is expanded again without transfer of heat but with a temperature drop.
This series of operations, known as Carnot's cycle, shows that even under ideal conditions a heat engine cannot convert into mechanical energy all the heat energy supplied to it; some of the heat energy must be rejected.

If the work required to drive the heat pump was less than the work given off by the heat engine (hence the need for a variable work output requirement for this thing to work), then using two differing heat reservoirs you could produce unlimited work.
Carnot was, however, a strong believer in the impossibility of perpetual motion, so he used this whole scenario as proof that there can be no variation in the work output of an ideal heat engine if the heat input Q

 Biological Energy
Carnot saw that it did not matter if the hill and water wheel were at sea level or on top of a mountain, what was important was the difference between the two heights (6 meters in this case).
He was able to show that entropy could be measured and expressed in units of calories per degree Celsius.
Carnot realized that in any practical conversion of fuel (wood, coal, oil) into heat and then into mechanical work (turning a steam engine), some part of the stored energy (the potential energy) is always lost of dissipated and does no useful work.

He saw that, in a steam engine, motive power is produced when heat "drops" from the higher temperature of the boiler to the lower temperature of the condenser, just as water, when falling, provides power in a waterwheel.
Several factors might account for this delay in recognition; the number of copies printed was limited and the dissemination of scientific literature was slow, and such a work was hardly expected to come from France when the leadership in steam technology had been centred in England for a century.
Eventually Carnot's views were incorporated by the thermodynamic theory as it was developed by Rudolf Clausius in Germany (1850) and William Thomson (later Lord Kelvin) in Britain (1851).
