  1. Santa Fe InstituteComplex Systems Summer School 2003

  2. Summer school activities • Lectures on ‘foundation’ topics: nonlinear dynamics, information theory, statistical mechanics, computational mechanics, agent-based modelling, adaptive computation • Lectures on specific application areas: RNA folding, economic game theory, emergent engineering • Experimental laboratory

  3. Belousov-Zhabotinsky Reaction Motion of a shaken hanging chain A. Belmonte et al (1997) Journal de Physique II 7, 1425-1468.   A Belmonte et al (2001) Physical Review Letters, 87, 114301

  4. Foam coarsening Faraday experiment

  5. 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

  6. Lorenz equations

  7. Periodic and strange attractors

  8. Malkus waterwheel

  9. Equations of Motion Mass change in each cup: Torque balance for wheel: Angle change for each cup:

  10. Simulated mass time series

  11. Angular velocity Lorenz equations time series Waterwheel equations time series

  12. Model-data comparison

  13. 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

  14. Reconstructed waterwheel attractors (simulation data) Reconstructed Lorenz attractors

  15. Reconstructed attractors from model and measured time series

  16. Acknowledgments • Andrew Belmonte, Department of Mathematics, Pennsylvania State University • Ray Goldstein, Physics Department, University of Arizona
