Persi Diaconis, Stanford mathematician. Chaos is not the same as randomness.
a system can follow clear laws and still remain practically unpredictable. not because of randomness, but because the smallest difference at the beginning can eventually lead to a completely different outcome.
in the lecture, they explain the key distinction: randomness means the outcome is not predetermined. chaos means the outcome is predetermined, but predicting it accurately requires knowing the initial conditions with impossible precision.
that is why rules do not always give us control. weather, markets, and even simple physical systems can follow strict laws - and still break long-term forecasts.
33 minutes after which “it follows the rules” will no longer mean “it can be predicted.”
