Thermodynamics the work of French physicist Nicolas Léonard Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scots-Irish physicist Lord Kelvin was the first to formulate a concise definition of thermodynamics in 1854 which stated, "Thermo-dynamics is the subject of the relation of heat to forces acting between contiguous parts of bodies, and the relation of heat to electrical agency." The initial application of thermodynamics to mechanical heat engines was extended early on to the study of chemical compounds and chemical reactions. Chemical thermodynamics studies the nature of the role of
History of the Jews in 19th-century Poland History of the Jews in 19th-century Poland Jewish Polish history during the 19th century: Official Russian policy would eventually prove to be substantially harsher to the Jews than that under independent Polish rule. The lands that had once been Poland were to remain the home of many Jews, as, in 1772, Catherine II, the tzarina of Russia, instituted the Pale of Settlement, restricting Jews to the western parts of the empire, which would eventually include much Poland although it excluded some areas in which Jews had previously lived.
