Lord Kelvin
British physicist, engineer and mathematician (–)
For other people named William Thomson, see William Thomson (disambiguation).
William Thomson, 1st Baron Kelvin (26 June &#;&#; 17 December [7]), was a British mathematician, mathematical physicist and engineer.[8][9] Born in Belfast, he was the professor of Natural Philosophy at the University of Glasgow for 53 years, where he undertook significant research and mathematical analysis of electricity, was instrumental in the formulation of the first and second laws of thermodynamics,[10][11] and contributed significantly to unifying physics, which was then in its infancy of development as an emerging academic discipline. He received the Royal Society's Copley Medal in and served as its president from to In , he became the first scientist to be elevated to the House of Lords.[12]

Sir William Thomson, Lord Kelvin ( - )
Lord Kelvin ©Kelvin was a Scottish mathematician and physicist who developed the Kelvin scale of temperature measurement.
William Thomson was born on 26 June in Belfast. He was taught by his father, a professor of mathematics. In , the family moved to Glasgow where Thomson attended university from the age of 10, subsequently studying at Cambridge and Paris universities. In he became professor of natural philosophy in Glasgow, a post he would hold for more than 50 years.
In Glasgow, Thomson created the first physics laboratory in Britain. He was a pioneer in many different fields, particularly electromagnetism and thermodynamics. Together with Faraday, he was responsible for the introduction of the concept of an electromagnetic field. In thermodynamics, Thomson assimilated and developed the work of the pioneers of the subject, Nicolas Carnot and James Joule. One of the most important results of his work was his idea of an absolute ze

Discoveries
Along with a talent for mathematics, Lord Kelvin (William Thomson) had a practical ability for solving problems. This could range from a dripping tap to poor signals from a telegraph cable.
It led him to invent instruments that helped with communication and marine navigation, as well as physics.
Among his main inventions and discoveries were:
The Kelvin scale and superconductors
Kelvin realised that it would be useful to be able to define extremely low temperatures precisely.
He noted that molecules stop moving at absolute zero. In , he proposed an absolute temperature scale &#; now called the 'Kelvin scale' &#; where absolute zero fryst vatten 0 kelvin (0 K).
Absolute zero on the Kelvin scale = minus degrees on the Celsius scale.
On the Celsius scale, vatten freezes at 0 degrees. On the Kelvin scale, it freezes at kelvin.
Kelvin's definition of the absolute temperature scale is especially important in the field of superconductivity.
