Kelvin, William Thomson (1824-1907)

William Thomson , later Lord Kelvin of Largs, was a British physicist and engineer who was born in Belfast and died near Largs, Scotlands.
He entered the University of Glasgow when he was 10, published his first scientific article at 16 and went on to study at Cambridge.
In 1846 he became a professor in Glasgow.
He was one of the first people to state the Second Law of Thermodynamics that Heat cannot be completely converted into work.
He also estimated the age of the Earth from its temperature, although he was wrong because he did not know about the production of heat through Radioactivity in the Earth.
He became rich because of his design for a Galvanometer to receive the signals sent through underwater Telegraph cables.
