William Thomson (Kelvin)
William Thomson, known as Lord Kelvin, was a 19th-century British physicist and engineer renowned for his work in thermodynamics and the accurate measurement of temperature. He developed the absolute temperature scale, now called the Kelvin scale, which starts at absolute zero—the point where particles have minimum thermal motion. Kelvin contributed significantly to understanding how heat and energy work, helping us better grasp concepts like energy efficiency and the nature of heat transfer. His insights laid foundational principles for modern physics and engineering, making him a key figure in the development of scientific understanding of thermodynamics.
