Thermodynamics: History through whom most physicists learned of Carnot s work, Benoit Pierre EmileClapeyron,6 was a firm adherent of the idea that heat was a material fluid. http://thermodynamicstudy.net/history1.html
Extractions: The History of Thermodynamics With the aid of these new concepts he proceeded, in one of the most brilliant feats of the imagination in the history of science, to show that with a heat reservoir at a given temperature from which heat could be taken by a working substance, and with another reservoir at a lower temperature into which it could reject heat, the greatest possible amount of mechanical work can be obtained when all the processes undergone by the working substance are reversible. The argument runs, in brief, as follows: Suppose we have an engine whose working substance, e.g., steam, takes an amount of heat (H) from a hot reservoir (such as a steam boiler), does an amount of work (W) on an external load, rejects an amount of heat (h) to a cooler reservoir, and is then returned to its original condition, so that the process can be repeated indefinitely. If all these operations can be imagined to be performed reversibly the engine will, when the work (W) is done upon it in each cycle by an outside agency, run in the reverse direction, taking the heat (h) from the cooler and delivering the heat (H) to the hotter reservoir in each cycle. previous page next page More of thermodynamics

Extractions: Died: Aug. 24, 1832, Paris), French scientist who described the Carnot cycle, relating to the theory of heat engines. Carnot was the eldest son of the French Revolutionary figure Lazare Carnot and was named for a medieval Persian poet and philosopher, Sa'di of Shiraz. His early years were a period of unrest, and the family suffered many changes of fortune. His father fled into exile soon after Sadi's birth; in 1799 he returned to be appointed Napoleon's minister of war but was soon forced to resign. A writer on mathematics and mechanics as well as military and political matters, the elder Carnot now had the leisure to direct his son's early education. During Napoleon's brief return to power in 1815, Lazare Carnot was minister of the interior, but, following the emperor's final abdication, he fled to Germany, never to return to France. Sadi remained an army officer for most of his life, despite disputes about his seniority, denial of promotion, and the refusal to employ him in the job for which he had been trained. In 1819 he transferred to the recently formed General Staff but quickly retired on half pay, living in Paris on call for army duty. Friends described him as reserved, almost taciturn, but insatiably curious about science and technical processes. The problem occupying Carnot was how to design good steam engines. Steam power already had many uses-draining water from mines, excavating ports and rivers, forging iron, grinding grain, and spinning and weaving cloth-but it was inefficient. The import into France of advanced engines after the war with Britain showed Carnot how far French design had fallen behind. It irked him particularly that the British had progressed so far through the genius of a few engineers who lacked formal scientific education. British engineers had also accumulated and published reliable data about the efficiency of many types of engines under actual running conditions; and they vigorously argued the merits of low- and high-pressure engines and of single-cylinder and multicylinder engines.

Extractions: Amin's Cycle In the interest of balance Eric Krieg requested I add a link to his site, http://www.phact.org/e/z/amin.htm Personally I have never seen any place where Amin has claimed to over come friction. Update: Seems that Amin has left town under the specter of some kind of farad. Keep that in mind when reading the following information. I've left it as it was for historical reference.

Boltzmann (Ludwig) : (Wien, 1844- Trieste, 1906) ce physicien viennois se consacra essentiellement à la théorie cinétique des gaz, c'est à dire à la répartition statistique des vitesses des molécules dans un gaz à une température donnée, mais ses concepts de mécanique statistique ont été exploités avec succès dans la théorie électronique où l'on a parfois considéré les électrons quasi-libres comme un "gaz d'électrons". Boole Bourdon Braun A ne pas confondre avec son homonyme Wernher von Braun Bravais Burroughs Cailletet (Louis) : (Chatillon sur Seine, 1832- Paris,1913) physicien et industriel français,. Il s'intéressa d'abord à la métallurgie et aux propriétés du fer (en travaillant dans les forges de la Côte d'Or), puis il s'intéressa aux gaz et tout particulièrement à l'hydrogène (propriétés de diffusion). Mais on le connait surtout comme auteur de travaux sur la liquéfaction des gaz (vers 1877) en particulier de tous ceux alors considérés comme "permanents" tels l'azote, l'oxygène, l'acétylène. C'est le père de l'air liquide et de toutes les applications qui en découlent. Il entra à l'Académie des Sciences en 1884.
