These millions of cells must work in sync, contracting in just the right sequence at just the right time to produce a healthy heartbeat. If you would like to play the animation again, double click the refresh button in the top right corner. Once this computer program was up and running, Lorenz could produce long-term forecasts by feeding the predicted weather back into the computer over and over again, with each run forecasting further into the future. How can order on a small scale produce chaos on a larger scale? We can see that after many bounces, the trajectory of the ball converges to the horizontal. Each red ball when pocketed remains in the pocket, while the colours when pocketed, as long as any reds remain on the table, are placed on their respective spots. Interestingly, what we get is an elliptical caustic curve that shares the same foci as the elliptical table, and so these are confocal ellipses. The ellipse is then the locus of all points such that the sum of the distances from these two foci is always a constant. But we know from the aforementioned definition of the ellipse that any such path must have exactly the same length!

Suppose they were all at the exact same point on Earth (which they won't be, thus mitigating the effects of the jump). Notice that three points are aligned: the point marking your position, the point on the mirror where you see the reflection of the object and the (imaginary) point behind the mirror where you believe the object to be. Although I don't usually like hacking stuff to get it for free, I think the clothes are a noble exception. Ceres, the solar system's largest asteroid, has less than 1/40,000th the mass of Earth; the Moon, a mere 1/80th. These objects are the heaviest you're likely to find - there are heavier moons and entire planets you could consider using, but to be honest from this point of view it looks more like using a succession of hundreds, thousands or tens of thousands of smaller asteroid impacts would be a better bet. 2. For which numbers does the arithmetic billiard path end in the corner opposite to the starting point? One fascinating aspect of mathematical billiards is that it gives us a geometrical method to determine the least common multiple and the greatest common divisor of two natural numbers. During play, when a player cannot hit the ball that the rules require him to hit (because of obstruction by another ball or balls), he is said to be snookered and loses his turn; this situation gives the game its name.

Scaling up the picture from the previous example by a factor of 3 then gives us this picture. The mathematician Ian Stewart used the following example to illustrate an attractor. 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. But why stop there? Carom billiards involves players scoring points by bouncing the cue ball off the opponent’s ball and into a pocket. Players take turns shooting, aiming to pocket objects. The player continues shooting as long as they legally pocket balls. The break shot starts the game, where a player strikes the racked balls with the cue ball. The player who pots the 9-ball wins. Scoring a carom also entitles the player to another shot, and his turn, or inning, continues until he misses, when it becomes his opponent’s turn. The skill involved consists of developing one scoring stroke after another. Phase space may seem fairly abstract, but one important application lies in understanding your heartbeat. Rather than simply bouncing off, the object destroyed much of both itself and Earth, causing a VAST spray of matter to be hurled off from the impact point; this matter coagulated into what is now the Moon.

The principle here is much the same, with the railguns behaving somewhat like discretized versions of thrusters, what is billiards providing instantaneous changes in velocity as opposed to sustained steady change. The major problem here is figuring out how to pick up big pieces of continental plate without breaking them. If you can tease out the pattern’s underlying chaotic systems, you can effect a measure of control over randomness and turn instability into an asset. You can challenge the clock and compete against other swimmers in this state-of-the-art swimming facility while you swim laps by yourself in the pool. While looking at an object in a mirror, you have the impression that the object is behind the mirror. What happens if you play billiards on an elliptical table, with no friction? Over the centuries, billiards gained popularity among the elite and eventually became a beloved pastime for people of all backgrounds. What’s the best way to improve my billiards skills? Intermagus has made some nifty little 6-tile billiards lamps for - what else - your billiards rooms.
