This episode is about chaos, or more specifically non-linear dynamics and sensitive dependency on initial conditions. We talk to Harry Swinney and Michael Marder, both from UT Austin’s Center for Nonlinear Dynamics. We discuss the basics of chaos, the kinds of systems that exhibit chaotic behavior, fractals, the phase space and the strange attractor. We also discussed practical applications of chaos theory and Harry’s and Michael’s current work.
