=William Thomson, Lord Kelvin=

"When you are face to face with a difficulty, you are up against a discovery."
Sir Willian Thomson, or better known as Lord Kelvin, lived from the year 1824 to 1907. He was a very famous British mathematical physicist and engineer. He became famous through his **Law of Thermodynamics** and unification of the emerging discipline of physics in its modern form



In 1851, together with fellow scientist Rudolph Clausius, he published his findings about the **Second Law of Thermodynamics**.
Basically the Second Law of Thermodynamics claims that heat generally cannot flow spontaneously from a material at lower temperature to a material at higher temperature.

He changed the existing view of heat as being a fluid to an understanding of the energy of motion of molecules. The term "Kinetic Energy" was introduced by Lord Kelvin, in 1856.

Both the Kelvin Scale and Kelvin (K), the SI unit for temperature, is named after Lord Kelvin, as he was the one who wrote of the need for an "absolute thermometric scale".
