A six-volume collection of the scientific papers of Lord Kelvin (18241907), one of Britain's most eminent mathematical physicists.This collection brings together in six volumes the published articles of the eminent mathematical physicist and engineer William Thomson, first Baron Kelvin (18241907). Topics covered include heat, electricity, magnetism and electrotelegraphy, hydrodynamics, tidal theory and navigation.This collection brings together in six volumes the published articles of the eminent mathematical physicist and engineer William Thomson, first Baron Kelvin (18241907). Topics covered include heat, electricity, magnetism and electrotelegraphy, hydrodynamics, tidal theory and navigation.William Thomson, first Baron Kelvin (18241907), is best known for devising the Kelvin scale of absolute temperature and for his work on the first and second laws of thermodynamics, though throughout his 53-year career as a mathematical physicist and engineer at the University of Glasgow he investigated a wide range of scientific questions in areas ranging from geology to transatlantic telegraph cables. The extent of his work is revealed in the six volumes of his Mathematical and Physical Papers, published from 1882 until 1911, consisting of articles that appeared in scientific periodicals from 1841 onwards. Volume 2, published in 1884, includes articles from the period 18531856, and puts a special emphasis on the issue of the development of electric telegraphy. Also included is Thomson's Bakerian Lecture on the electro-dynamic qualities of metals.64. On the mutual attraction and repulsion between two electrified spherical conductors; 65.
