The Geometry of Chaos
Like Duolingo, but for The Geometry of Chaos. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.

Key ideas in The Geometry of Chaos
- Deterministic systems follow fixed rules but can still be unpredictable
- A positive Lyapunov exponent indicates chaotic divergence
- Small initial differences grow exponentially in chaotic systems
- The distance between trajectories grows exponentially over time
- The distinction between deterministic rules and long-term predictability
- How the Lyapunov exponent quantifies the rate of divergence
- The exponent is derived from the ratio of final to initial separation
- Logarithmic scales are used to linearize exponential growth rates
- The process of calculating the Lyapunov exponent from a sequence of states
- A single time series contains 'echoes' of all other variables it interacted with
- Lagged versions of the data act as proxies for the missing dimensions
- Time lag must be large enough to let the system evolve but small enough to maintain a relationship
- Embedding dimension must be high enough to 'unfold' the geometry
- The practical consequences of choosing reconstruction parameters
- Reconstruction starts with a 1D stream and ends with a geometric object
- The conceptual mechanism of Takens' Embedding Theorem
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives The Geometry of Chaos the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
