Nicolas Léonard Sadi Carnot (1796–1832) Sadi Carnot was the eldest son of Lazare Carnot and he was born in the Palais du Petit-Luxembourg. His younger brother was Hippolyte Carnot. At the time of Sadi's birth, his father was a member of the Directory, the French Revolutionary government which lasted four years from November 1795 to November 1799. Sadi was given named after a medieval Persian poet and philosopher called Sadi of Shiraz. 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. His father was appointed to the high office of Napoleon's minister of war in 1799. Lazare Carnot resigned in 1807 and devoted himself to the education of his two sons. His famous work on the motive power of heat (Réflexions sur la puissance motrice du feu, 1824 is concerned with the relation between heat and mechanical energy. 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. The gas is then compressed, heat being given off, and finally it is returned to its original condition by another compression, accompanied by a rise in temperature. 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. This is an illustration of the second law of thermodynamics. Carnot's work anticipated that of Joule, Kelvin, and others.

CheckFrames(document.URL); b. 11 Aug 1837, Limoges, Haute-Vienne Title: Term: 3 Dec 1887 - 25 Jun 1894 Chronology: 25 Jun 1894, deceased (assassination) The grandson of Lazare Carnot , Carnot as a candidate of the left was elected president of the Republic on the second ballot (3 Dec 1887). Carnot faced the movement led by General Boulanger, which threatened to topple the Third Republic by conspiring with monarchists and attempts to replace the constitution with more authoritarian law. In 1889 the government of Pierre Tirard succeeded in preventive measures and decided to prosecute Boulanger, who fled to Belgium. In May 1891 the workers' demonstration with demands of 8-hour working day resulted in casualties. A new crisis arose from the Panama scandal (1892), when the press discovered that the Panama Canal Company bribed the French politicians in effort to save the collapsing project. The republican regime survived the crisis, but the scandal added strength to the socialist movement. After delivering a speech at a Lyon exposition, at about 9 p.m. on 24 Jun 1894, Carnot was stabbed by the Italian anarchist Sante Caserio, who approached the presidential cortege. Carnot died after three hours of agony soon after midnight (25 Jun 1894).

Sadi Carnot and the Conservation of Energy Vince Ciricola Sadi Carnot was a proponent of the caloric theory, as were nearly all of the prominent figures prior to Joule. He never published anything that varied from that view although he may have indicated otherwise in some of his correspondence. It is interesting to note that Sadi Carnot and Emil Clapeyron were both engineers (Joule was not an engineer). Together they established the foundation on which the science of thermodynamics was built, primarily by physicists. Carnot is one of the few engineers in history who has name recognition. Emil Clapeyron rescued Carnot's paper from almost certain obscurity; he is responsible for the graphical depiction of this cycle familiar to all thermodynamic students and the equations associated with it . It is a testimony to Carnot that despite an incorrect notion on the nature of heat the Carnot Cycle/Engine is an indispensable part of virtually all college thermodynamic courses.

Suite à la démission de Jules Grévy, mis en cause dans le scandale des décorations, Sadi Carnot fut élu Président de la République le 3 décembre 1887. Le début de son mandat fut marqué par l’agitation boulangiste (il signa le décret mettant à la retraite d’office le Général Boulanger), par le ralliement de nombreux catholiques au régime républicain (1890) et les scandales de Panama (1892). Casimir-Perier venait de faire voter les "lois scélérates" visant à réprimer l’agitation syndicale et anarchiste quand Carnot fut assassiné par l’anarchiste Caserio le 24 juin 1894 lors de l’Exposition de Lyon.

Nicolas Léonard Sadi Carnot (Paris 1st June 1796 - 24 August 1832) Eldest son of Lazare Carnot, brother of Hippolyte. Physicist known as the founding father of thermodynamics. Sadi was received twenty-fourth at Ecole Polytechnique in 1812, at the age of sixteen years, where he graduated at the top of his class in Artillery. He fought against the allies with the polytechnicians' battalion during the defense of the Vincennes Fort in 1824. As a candidate to join the General Staff in 1819, he was accepted with the rank of Lieutenant. He left the army with the rank of Captain in the Corps of Engineers in 1828 to settle in Paris. He died there of cholera at the age of thirty-six years, without any heirs. Sadi Carnot is known as the founder of thermodynamics. He published, at his expenses, in 1824 his Reflections on the motive power of fire Réflexions sur la puissance motrice du feu et sur les machines propres à développer cette puissance -. It is in this book of less than a hundred-and-twenty pages and limited to only six hundred copies that he founded what we call today the Second law of thermodynamics or Carnot's Principle . As for the first principle, on the conservation of energy, he also discovered it before the end of his life, as showed by his posthumous papers, published in 1878.

Nicolas Léonard Sadi Carnot (1776 - 1832) französischer Ingenieur Carnot wurde am 1. Juni 1776 in Paris geboren. Von 1812 bis 1814 studierte er Mathematik, Chemie und Mechanik an der École Polytechnique in Paris. Anschließend war er als Ingenieur beim französischem Militär tätig. Er führte 1824 den nach ihm benannten Carnot-Prozess bei Wärmekraftmaschinen ein und bestimmte den maximal möglichen Wirkungsgrad der idealen Wärmekraftmaschine (siehe auch Stirlingmaschine). Im selben Jahr (1824) publizierte er seine Forschungsergebnisse in seinem Buch "Réflexions sur la puissance motrice du feu et sur les machines propres à développer cette puissance". 1828 ging er in den Ruhestand um sich ganz seinen wissenschaftlichen Studien widmen zu können. Ab 1830 untersuchte er die Beziehungen zwischen Temperatur und Druck bei Gasen und berechnete das mechanische Wärmeäquivalent. Nicolas Léonard Sadi Carnot verstarb am 24. August 1832 in Paris

Carnot - la thermodynamique et les premières machines Sadi Carnot (1796-1832) est un des fondateurs de la thermodynamique. Après avoir épousé la théorie, qui prévalait à l'époque, que la chaleur est une forme de matière, il écrit en 1831, un an avant sa mort à l'age de 36 ans: «Lorsqu'une hypothèse ne suffit plus à l'explication des phénomènes, elle doit être abandonnée. C'est le cas où se trouve l'hypothèse par laquelle on considère le calorique comme une matière, comme un fluide subtil. [...] La chaleur n'est autre que la puissance motrice [...] qui a changé de forme.» Il poursuivait: «On peut donc poser en thèse générale que la puissance motrice est en quantité invariable dans la nature, qu'elle n'est jamais à proprement parler ni produite, ni détruite. A la vérité, elle change de forme...» Carnot énonçait ainsi, quinze ans avant James Joule, la première loi de la thermodynamique. La machine idéale de Carnot, réversible et sans frottement, a permis de comprendre la conversion de chaleur en travail. Né du besoin de faire rendre le plus de travail possible à une quantité donnée de charbon, le développement de meilleures machines à vapeur était, depuis Denis Papin, l'objet d'une intense activité.

Carnot, (Nicolas Leonard) Sadi French scientist and military engineer who founded the science of thermodynamics. His pioneering work was Reflexions sur la puissance motrice du feu/On the Motive Power of Fire, which considered the changes that would take place in an idealized, frictionless steam engine. Carnot's theorem showed that the amount of work that an engine can produce depends only on the temperature difference that occurs in the engine. He described the maximum amount of heat convertible into work by the formula (T1 T2)/T2, where T1 is the temperature of the hottest part of the machine and T2 is the coldest part. Carnot was born in Paris and educated there and at the Ecole Genie in Metz. He became an army engineer, at first inspecting and reporting on fortifications and from 1819 based in Paris. In formulating his theorem, Carnot considered the case of an ideal heat engine following a reversible sequence known as the Carnot cycle. This cycle consists of the isothermal expansion and adiabatic expansion of a quantity of gas, producing work and consuming heat, followed by isothermal compression and adiabatic compression, consuming work and producing heat to restore the gas to its original state of pressure, volume, and temperature. Carnot's law states that no engine is more efficient than a reversible engine working between the same temperatures. The Carnot cycle differs from that of any practical engine in that heat is consumed at a constant temperature and produced at another constant temperature; no work is done in overcoming friction at any stage; and no heat is lost to the surroundings.
