Lord Kelvin or William Thompson was a famous physicist, mathematician and engineer, who is best known for his work in the mathematical analysis of electricity. Born to a mathematician father in the 19th century, he was tutored in advanced mathematics from his early childhood and became an accomplished mathematician while still in school. He continued studying science and mathematics at the ‘University of Cambridge’. At the age of 22, he joined the ‘University of Glasgow’ as a professor of natural philosophy, a branch of academics we now know as physics. In spite of invitations from more renowned universities, Kelvin remained at the Glasgow for 50 years. During his long scientific career, he wrote 600 papers. He played an important role in the formulation of the second law of thermodynamics. The absolute temperature scale’s base unit Kelvin ‘K’ is named in his honor. Apart from having a profound influence on the scientific thought of that era, he is also known for his contributions in laying the transatlantic telegraph cable.
