Thomson, William

Thomson, William ( Lord Kelvin) (1824–1907) A mathematician and physicist at Glasgow University, Kelvin is best known for his theory of thermodynamics, which he applied to his work on the age of the Earth. He used studies of the internal heat of the Earth, the age of the Sun, and tidal friction, to give an estimate of the Earth's age of about 20 million years. This led to conflict with geologists and evolutionists, who saw evidence that the Earth must be much older. See KELVIN SCALE.
