GROWTH LIMITS. "Conway conjectures that no pattern can grow without limit. Put another way, any configuration with a finite number of counters cannot grow beyond a finite upper limit to the number of counters on the field. This is probably the deepest and most difficult question posed by the game." https://lnkd.in/dN_g3Fs View in LinkedIn

XYLEM AND PHLOEM. "An intact and functioning nutrient transport system is a requirement for communication between the sites of perception in the leaves and the sites of response. Daylength response is lost when the pathway is disrupted by removing the source leaf, inhibiting transport by localized heat or cold treatments applied at intermediate points in the transport path or stem girdling." https://lnkd.in/d_f7kfY View in LinkedIn

MARTIN GARDER ON LIFE. "In a few cases the society eventually dies out (all counters vanishing), although this may not happen until after a great many generations. Most starting patterns either reach stable figures--Conway calls them "still lifes"--that cannot change or patterns that oscillate forever. Patterns with no initial symmetry tend to become symmetrical. Once this happens the symmetry cannot be lost, although it may increase in richness." https://lnkd.in/dN_g3Fs View in LinkedIn

SMALL DIFFERENCES MAGNIFY, as shown in the Game of Life. See this very compelling lecture by Stanford's Professor Sapoloski. The simplest of rules in this computer game is similar to those of living systems. https://lnkd.in/d2JdRWs View in LinkedIn

"THE GAME OF LIFE is not your typical computer game. It is a 'cellular automaton', and was invented by Cambridge mathematician John Conway. This game became widely known when it was mentioned in an article published by Scientific American in 1970. It consists of a collection of cells which, based on a few mathematical rules, can live, die or multiply. Depending on the initial conditions, the cells form various patterns throughout the course of the game." https://lnkd.in/dVq7BAk View in LinkedIn

LARGE POPULATION. "Life enthusiasts have since catalogued an entire zoo of interesting patterns, such as “spaceships” that travel across the grid, or “guns”, which constantly spawn other patterns. But a pattern that spawned an identical copy of itself proved elusive." Too bad nomenclatures were not biological. https://lnkd.in/d5EF-mB View in LinkedIn

GREEN'S REPLICATOR. "Basically, it is the last step before an actual replicator pattern is built!" "Highlife-like replicators, here we come! I think the first "true" replicator will be built in about 2020. For the 50th anniversary of life" (Game of Life). https://lnkd.in/djU8N2U View in LinkedIn

FIRST REPLICATOR. "On November 23, 2013, Dave Greene built the first replicator in Conway's Game of Life that creates a complete copy of itself, including the instruction tape." https://lnkd.in/dzs-Kxk View in LinkedIn

SELF-CONSTRUCTING CIRCUITRY. "In 2010, something better did come along: Andrew Wade's Gemini spaceship magically appeared on the scene, and things suddenly got much easier for would-be replicator designers. Self-constructing circuitry was no longer just a theoretical possibility but an accomplished fact -- and the Gemini made it look downright easy." https://lnkd.in/dNTQG9j View in LinkedIn

CUMBERSOME START. "In 2009, Adam P. Goucher put together a working universal computer-constructor that could be programmed to make a complete copy of itself. The pattern, however, is so huge and slow that it would have taken an enormous amount of work to program it to self-replicate -- it would have been easier to come up with a new replicator design from scratch. Clearly, in hindsight, everyone was waiting for something better to come along." https://lnkd.in/dNTQG9j View in LinkedIn
