Chaos you can play in:the Malkus Waterwheel Aaron Clauset, Nicky Grigg, May Tan Lim, Erin Miller Santa Fe Institute Complex Systems Summer School June 2003
Equations of Motion Mass change in each cup: Torque balance for wheel: Angle change for each cup:
Angular velocity Lorenz equations time series Waterwheel equations time series
Phase space reconstruction • Delay coordinate embedding requires a delay time (t) and an embedding dimension (dE) • Delay time from first minimum in average mutual information function • Embedding dimension from false nearest neighbours analysis
Reconstructed waterwheel attractors (simulation data) Reconstructed Lorenz attractors
Reconstructed attractors from model and measured time series
