Walther Nernst

Walther Nernst (1864-1941), was a distinguished German chemist and physicist who helped establish the modern foundation of physical chemistry. He is most famous for formulating the Third Law of Thermodynamics in 1906, which states that as a system approaches absolute zero, its entropy reaches a constant minimum. This profound discovery earned him the 1920 Nobel Prize in Chemistry. Nernst also developed the Nernst equation, a fundamental formula in electrochemistry that relates the voltage of a chemical cell to its concentration gradients. A highly practical inventor, he created the Nernst lamp, an early, efficient electric light bulb. During his later years, Nernst was a vocal opponent of Adolf Hitler and the Nazi regime, bravely rejecting their pseudoscientific racial theories. His brilliant combination of thermodynamics and chemistry left a permanent legacy across physical sciences, engineering, and industry.
