Though we may not be able to predict exactly how a chaotic system will behave moment to moment, knowing the attractor allows us to narrow down the possibilities. The best we can do for three bodies is to predict their movements moment by moment, and feed those predictions back into our equations … Although the computer’s new predictions started out the same as before, the two sets of predictions soon began diverging drastically. In mathematical billiards the ball bounces around according to the same rules as in ordinary billiards, but it has no mass, which means there is no friction. A difference of one part in a thousand: the same sort of difference that a flap of a butterfly’s wing might make to the breeze on your face. On the other hand, this stability is somewhat of an inconvenience to fighter pilots who prefer their aircraft to make rapid changes with minimal effort. The game was played on a huge strip of land, in this case about 1000 yards long and so was more like golf than Croquet - players took great swings at the balls in an effort to hoof them as far along the pitch as possible. Eight Ball is a call shot game played with a cue ball and fifteen object balls, numbered 1 through 15. One player must pocket balls of the group numbered 1 through 7 (solid colors), while the other player has 9 thru 15 (stripes).

No matter how consistent you are with the first shot (the break), the smallest of differences in the speed and angle with which you strike the white ball will cause the pack of billiards to scatter in wildly different directions every time. A stained glass window in England's Gloucester Cathedral, dating from the mid-fourteenth century, shows a figure wielding a stick in the middle of a distinctly golf-like backswing or high-powered croquet shot.

The millions of cells that make up your heart are constantly contracting and relaxing separately as part of an intricate chaotic system with complicated attractors. They are also designed with cloth that is intended to make the ball slide more slowly across the table. No matter where it starts, the ball will immediately move in a very predictable way towards its attractor - the ocean surface. The purpose of a defibrillator - the device that applies a large voltage of electricity across the heart - is not to "restart" the heart cells as such, but rather to give the chaotic system enough of a kick to move it off the fibrillating attractor and back to the healthy heartbeat attractor. A chaotic system will also move predictably towards its attractor in phase space - but instead of points or simple loops, we see "strange attractors" appear - complex and beautiful shapes (known as fractals) that twist and turn, intricately detailed at all possible scales. Fortunately, this intricate state of synchronisation is an attractor of the system - but it is not the only one. The branch of fractal mathematics, pioneered by the French American mathematician Benoît Mandelbröt, allows us to come to grips with the preferred behaviour of this system, even as the incredibly intricate shape of the attractor prevents us from predicting exactly how the system will evolve once it reaches it.

The behaviour of the system can be observed by placing a point at the location representing the starting configuration and watching how that point moves through the phase space. Once there it clings to its attractor as it is buffeted to and fro in a literal sea of chaos, and quickly moves back to the surface if temporarily thrown above or dumped below the waves. If released above the water it will fall, and if released underwater it will float. This means that the ball will bounce infinitely many times on the sides of the billiard table and keep going forever. Carom shots require precise control of the cue ball’s speed and direction, making them a great way to showcase your mastery of cue ball manipulation. What at first glance appears to be random behaviour is completely deterministic - it only seems random because imperceptible changes are making all the difference. It was the first chaotic system to be discovered, long before there was a Chaos Theory. In the interests of saving time he decided not to start from scratch; instead he took the computer’s prediction from halfway through the first run and used that as the starting point.
