Irving Langmuir

Irving Langmuir was an influential American physical chemist known for his work in several areas, including plasma physics. He advanced our understanding of gases ionized into plasma—where electrons and ions interact. He introduced concepts such as Langmuir waves, which describe oscillations in plasma. Langmuir's research helped explain electron configurations and the kinetic theory of plasmas, which studies how particles behave in different energy states. His pioneering insights have been foundational in technologies like gas discharge lamps and semiconductors, bridging chemistry and physics to deepen our understanding of matter in various states.
