The Geometry of Chaos, a free math course on Tomo

The Geometry of Chaos

Master the hidden order within seemingly random systems. Learn to predict the unpredictable by exploring the deep mathematical structures of fractals, strange attractors, and nonlinear dynamics.

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.

A short one: 24 levels across 3 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Finding Order in the Noise, Measuring the Infinite, and The Mechanics of Complexity.

What you'll learn

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
