William Thomson, 1st Baron Kelvin

William Thomson, 1st Baron Kelvin, was a renowned 19th-century physicist and engineer who made significant contributions to thermodynamics and electrical science. He is best known for defining the absolute temperature scale, now called the Kelvin scale, which measures temperature from absolute zero, where particles have minimal motion. Kelvin’s work helped improve understanding of heat, energy, and electricity, influencing advances in technology and measurement. His research supported the development of efficient engines and telegraphy. Overall, Kelvin's insights laid foundational principles for modern physics and engineering, earning him a lasting legacy in scientific history.
