Scottish education in the nineteenth century world. His students founded practical chemistry at Aberdeen soon after. William Thomson, 1st Baron Kelvin was appointed to the chair of natural philosophy at Glasgow aged only 22. His work included the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics. By 1870 Kelvin and Rankine made Glasgow the leading centre of science and engineering education and investigation in Britain. At Edinburgh, major figures included David Brewster (1781–1868), who made contributions to the science of optics and to the development of photography. Fleeming Jenkin (1833–85) was the first professor of engineering at the university and
Laws of thermodynamics in several ways : More specifically, the First Law encompasses several principles: where denotes the amount of energy transferred into the system as heat. Combining these principles leads to one traditional statement of the first law of thermodynamics: it is not possible to construct a machine which will perpetually output work without an equal amount of energy input to that machine. Or more briefly, a perpetual motion machine of the first kind is impossible. The second law of thermodynamics indicates the irreversibility of natural processes, and, in many cases, the tendency of natural processes to lead towards spatial homogeneity of
