This is an excellent program, but I dislike that the presenter and one of the interviewees both say that chaotic systems are "inherently unpredictable". Chaotic (classical) systems are deterministic, so the same initial conditions will always give you the same result.<p>What makes them chaotic is that they are exponentially sensitive to initial conditions (i.e. "the butterfly effect"). This means that a difference that might go undetected in the initial condition can cause a potentially large change to the final result.
