2.2 (a) Lorenz Chaos (continued)
•This is a very simple system of equations with dissipation
•
•Like the damped pendulum, motions settle, but here to the chaotic attractor shown
•
•This could not have been discovered without the computers that appeared in the 1960s
•
•Since the solution is chaotic, it cannot be written down in any formula
•
•In a mathematical sense the problem is unsolvable
•
•All the computer does is solve the equations in an approximate way                                                      @
