Lord Kelvin (1824-1907),British physicist. Born William Thomson,he entered Glasgow University at the age of ten. Kelvin supported Joule's thermodynamics work and later proposed a law of the conservation of energy. In 1848 Kelvin proposed the existence of absolute zero and suggested the use of the absolute temperature scale,which was named the Kelvin scale. Kelvin worked in electromagnetism,being the first to use vectors to represent magnetic induction and magnetic force. He improved electric cable design,making trans-Atlantic telegraphy viable. 19th century engraving based on a photograph by John Fergus of Largs | |
