Sir William Thomson (Lord Kelvin)

Sir William Thomson, also known as Lord Kelvin, was a prominent 19th-century physicist and mathematician. He is best known for establishing the absolute temperature scale, known as the Kelvin scale, which is critical in thermodynamics. Thomson contributed to various fields, including the understanding of electricity and heat. He famously helped develop the first transatlantic telegraph cable. His work laid foundational principles in physics, and he emphasized the importance of rigorous scientific measurement. Lord Kelvin's insights continue to influence science and engineering today, making him a pivotal figure in the history of modern science.
