Purely for the sake of simplicity (because it doesn’t affect my argument at all), let’s say it’s a closed, deterministic, well-mixed system with no population structure or evolution or anything like that, so we can describe the dynamics with just two coupled equations, one for prey dynamics and one for predator dynamics. Here’s an example. It’s a population ecology example, but not because population ecology is the only bit of ecology that’s about dynamical systems. That’s why colliding billiard balls are a paradigmatic example of causality in philosophy. The example is predator-prey dynamics.

Records show a game called "crookey", similar to croquet, being played at Castlebellingham in County Louth, Ireland, in 1834, which was introduced to Galway in 1835 and played on the bishop's palace garden, what is billiards and in the same year to the genteel Dublin suburb of Kingstown (today Dún Laoghaire) where it was first spelled as "croquet". You knock over the first domino, which knocks over the second, which knocks over the third. And again for the sake of simplicity, let’s say it’s a constant environment and there’s no particular time at which organisms reproduce or die (e.g., there’s no "mating season"), so reproduction and mortality are always happening, albeit at per-capita and total rates that may vary over time as prey and predator abundances vary.

For example, placing a wood table in a room with high humidity could lead to warping over time, and extreme temperature changes can affect the table’s playability and longevity. If you’re not sure about the difference between these bulb types and how they would affect your pool table lighting design, here’s a quick overview. If you have a smaller table (i.e. 7 feet), you’ll be looking for a lighting fixture closer to 45 inches or smaller, and that uses 4 bulbs or fewer. In general, however, brighter colors do better with less light, darker colors need a little more to help visibility, and colors like green, blue, and tan tend to look good in just about any lighting. The term colour is understood to mean one of the six remaining object balls that are not red, i.e. yellow, green, brown, blue, pink, and black. Alternatively, if you have a 9-foot table, you could use a 4-shade design on a longer bar (i.e. 68") to cover the full playing surface.

To know who will begin the match, you will have to string, which can either be based on an imaginary line (head string) or the number of wins (scoring string). The toy car is pushed into a line of dominoes, the last of which falls onto another toy car, which rolls down a ramp and runs into a ball, which rolls down another ramp… You also win if your opponent accidentally pots the 8 ball, which is illegal. If you pocket the wrong ball, it’s called a foul, which gives your opponent a turn. The "on" balls are those that can be pocketed on any given turn. The game continues until every red ball has been potted and only the six colours and the cue ball are left on the table. Your cue strikes the cue ball, causing it to roll into another ball, causing that ball to roll into the corner pocket.

Losing Hazard: You score if you hit the other cue ball, which should then hit the red ball and pocket the ball to get three points. Winning Hazard: You pot the red ball to get three points. This "rolling" list is maintained and updated throughout the season, with points from tournaments played in the current season replacing points earned from the corresponding tournaments of two seasons ago. Keep in mind that these two other balls are already on the table and that the cue balls are white and yellow. To score points, which are known as counts, you need to bounce the cue ball off the other two balls. Pool balls, on the other hand, are made from two layers of rubber. MDF tables are often made with some type of plastic, thin metal, or particleboard. Pockets: Carom billiards tables do not have pockets at all, as the game does not involve potting balls but rather focuses on hitting object balls in a specific manner. Billiards is all about sequences of causal events. Falling dominoes are sequences of causal events. Note that these two other balls are already on the table, and remember that white and yellow are the cue balls.
