William Thomson (Lord Kelvin)

William Thomson, known as Lord Kelvin, was a 19th-century physicist who made significant contributions to thermodynamics, the study of heat and energy. He formulated the Kelvin scale of absolute temperature, which is crucial for understanding how heat energy behaves. He also helped establish the laws of thermodynamics, which describe how energy moves and transforms in physical systems. His work laid the groundwork for modern physics and engineering, particularly in understanding heat engines and refrigeration. Lord Kelvin’s insights helped explain the relationship between heat, work, and energy, fundamentally shaping our understanding of the physical world.
