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
Thermodynamics the laws of thermodynamics. The qualifier "classical" reflects the fact that it represents the first level of understanding of the subject as it developed in the 19th century and describes the changes of a system in terms of macroscopic empirical (large scale, and measurable) parameters. A microscopic interpretation of these concepts was later provided by the development of "statistical mechanics". Statistical mechanics, also called statistical thermodynamics, emerged with the development of atomic and molecular theories in the late 19th century and early 20th century, and supplemented classical thermodynamics with an interpretation of the microscopic interactions between individual particles or quantum-mechanical
