The invisible hand is an imaginary force, invented (arguably 'discovered') by Adam Smith, to explain the way that markets, composed of selfish desires, can have non-selfish consequences. It is a classic case of "emergence", where a thing of one type leads to a thing of an entire…

Common terms used within Conway's Game of Life. - **Ash** : The debris left behind by a random **pattern** . Commonly composed of still life and simple oscillators. - **Breeder** : any **pattern** that exhibits unbounded quadratic growth. The first and most famous example is Gosp…

A "still life" (in Conway's Game of Life) is any pattern that does not change from one generation to the next. Here are depictions of some of the most common types of still life. (The 'Play' button below will not achieve anything in these cases.) Block (or buoy) 0000 0110 011…

Some patterns in Conway's Game of Life appear to travel across the board, by performing oscillations that recreate the same shape, displaced in some direction. The three listed below all have a periodicity of 4. Glider The most famous, the first discovered, and by far the most…

Here are two famous **Methuselahs** : simple patterns that are long lived and grow quite large: Acorn and R-Pentomino. Acorn 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000…

A 'gun' (in the world of Cellular Automata) is a stationary pattern that emits moving patterns (i.e. spaceships). Note that a gun is a pattern which grows without limit. The first gun to be discovered was the Gosper Glider Gun. It is also the simplest known gun in Conway's Game…

Oscillators are patterns in Game of Life that cycle through a repeating set of states. The number of states in the cycle is called the "periodicity", e.g. "Period 2" means two states that alternate. Period 2 Blinker (period 2) 00000 00000 01110 00000 00000 Toad (Period 2) 00…

The Dragon Curve or Dragon Fractal is a nifty little shape! Here are the first 12 iterations. You see the dragon shape begin to emerge. I've put a red dot before each one, so you can see how it doesn't always go forward right away. ;export dragon to dragon :count :length :angle…

Space-filling curves! Amazing things. Peano sat around thinking and thinking, What was he thinking? He was thinking: I wonder, I wonder, I wonder! Can I draw a continuous line that touches every single point of the unit square, exactly once? (i.e. it never crosses itself!) No…

Swirls and spirals appear in nature in all kinds of places. In the seeds of a sunflower, in the vortex of a hurricane, in the horns of a goat, in the shell of a snail, in the curling fronds of a fern, in this guy's beard. . In this totally naturally occurring jetty: Spirals in…
