Thom•son, Sir William (1st Baron Kelvin of Largs) (1824-1907), British physicist. One of the most influential scientists of the 19th century, Thomson made important contributions in almost every branch of the physical sciences. He was a prolific inventor. He created the first physics laboratory in Great Britain and was the first to teach physics in a lab. He developed the Kelvin scale in 1848. From 1848 on he did thermodynamic research, often in collaboration with James P. Joule. Between 1851-54 Thomson helped to formulate the first two laws of thermodynamics. During the next few years he laid the theoretical foundations for submarine telegraphic transmission. He was the leading scientist involved in the laying of the transatlantic cable. He also made discoveries in electromagnetism and investigated wave motion and vortex motion.
adj : relating to, conforming to, or being the Kelvin scale .
