Theory Briefing
- Edward Lorenz's weather model showed that a minuscule input change could produce wildly different outcomes, birthing the butterfly effect metaphor.
- PBS NOVA's Athena Brensberger traces how that accidental discovery cascaded into the formal scientific framework known as chaos theory.
- Chaos theory reveals that complex systems are exquisitely sensitive to initial conditions, making long-term prediction fundamentally — not just practically — impossible.
