A propos de cet article

In-8, broché, couverture muette d'origine avec son cordon, tiré à part avec nouvelle pagination, extrait de Proceedings of the Royal Society of London, 5 pp., 1857. Le précurseur des recherches sur la conductivité des métaux, le tiré à part : William Thomson a complété dans cet article les conclusions de ses travaux faits l'année précédente sur la conductivité du nickel et du fer. Ces travaux essentiels ont ensuite servi à la recherche pour les câbles sous-marins. Le nombre de tirés à part à cette époque était de moins d'une quinzaine, ce qui explique la présence de cet article dans très peu d'institutions (deux exemplaires sont recensés à Berlin et à Glasgow). - - - - - The precursor of metal conductivity research, the reprint offprint : William Thomson has supplemented in this article the conclusions of his work done the previous year on the conductivity of nickel and iron. This essential work was then used for research into submarine cables. The number of offprint at that time was less than fifteen, which explains the presence of this article in very few institutions (two copies are recorded in Berlin and Glasgow). William Thomson, 1st Baron Kelvin, OM, GCVO, PC, FRS, FRSE (26 June 1824 - 17 December 1907) was a Scots-Irish mathematical physicist and engineer who was born in Belfast in 1824. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its modern form. He worked closely with mathematics professor Hugh Blackburn in his work. He also had a career as an electric telegraph engineer and inventor, which propelled him into the public eye and ensured his wealth, fame and honour. For his work on the transatlantic telegraph project he was knighted in 1866 by Queen Victoria, becoming Sir William Thomson. He had extensive maritime interests and was most noted for his work on the mariner's compass, which previously had limited reliability. Absolute temperatures are stated in units of kelvin in his honour. While the existence of a lower limit to temperature (absolute zero) was known prior to his work, Lord Kelvin is known for determining its correct value as approximately ?273.16 degree Celsius or ?459.67 degree Fahrenheit. He was ennobled in 1892 in recognition of his achievements in thermodynamics, and of his opposition to Irish Home Rule, becoming Baron Kelvin, of Largs in the County of Ayr. He was the first British scientist to be elevated to the House of Lords. The title refers to the River Kelvin, which flows near his laboratory at the University of Glasgow. His home was the red sandstone mansion Netherhall, in Largs. Despite offers of elevated posts from several world-renowned universities, Kelvin refused to leave Glasgow, remaining professor of Natural Philosophy for over 50 years, until his eventual retirement from that post. The Hunterian Museum at the University of Glasgow has a permanent exhibition on the work of Lord Kelvin including many of his original papers, instruments, and other artifacts, such as his smoking pipe. Active in industrial research and development, he was recruited around 1899 by George Eastman to serve as vice-chairman of the board of the British company Kodak Limited, affiliated with Eastman Kodak.
