What is Leon Cooper known for?
I am best known for my work on superconductivity, specifically the BCS theory—named for John Bardeen, Robert Schrieffer, and myself. We explained how certain materials conduct electricity with zero resistance at very low temperatures. The key insight was the Cooper pair: two electrons, which normally repel each other, can form a bound state through lattice vibrations, or phonons. This pairing allows them to move without scattering, eliminating resistance. That work earned us the Nobel Prize in Physics in 1972. Later in my career, I turned to neural networks and cognitive science, applying the physicist's habit of stripping problems down to their essentials to understand how the brain learns and stores memories. I've always been drawn to fundamental questions, whether in condensed matter or in the mind.
