A 1955 Los Alamos computer experiment changed our understanding of chaos
- LAsteNERD 5mo agoIn 1955, Mary Tsingou helped run a computational experiment at Los Alamos that revealed unexpected behavior in nonlinear systems—work that later became foundational to chaos theory and computational science. This piece traces that history from early supercomputers and the Fermi-Pasta-Ulam-Tsingou problem to modern AI systems used to explore uncertainty in scientific research.
