A group of scientists at the Santa Fe Institute are creating a new science called complexity. They are exploring interconnectedness, chaos, and order to understand nature, human behavior, and the universe. They want to know how life began, why ecosystems collapse, and how the economy behaves unpredictably. By studying these questions, they aim to uncover the common threads that connect them all. Their goal is to understand how complex structures like galaxies, plants, and brains emerge in the universe.
