Lorenz AttractorDrag to orbit, scroll to zoom. Two hundred thousand specks follow a stripped-down weather model. No two ever repeat a path, yet every one stays caught on the same butterfly-shaped surface — order and unpredictability in the same object.In 1961 Edward Lorenz reran a forecast from a rounded-off printout and got a wildly different result. Boiling convection down to three equations, he found trajectories that never settle and never cross — a “strange attractor.” The talk title stuck: does the flap of a butterfly’s wings in Brazil set off a tornado in Texas?
