The phrase '''''edge of chaos''''' was coined by [[computer scientist]] [[Christopher Langton]] in [[1990]]. The phrase originally refers to an area in the range of a [[variable]], λ (lambda), which was varied while examining the behavior of a [[cellular automata]] (CA). As λ varied, the behavior of the CA went through a [[phase transition]] of behaviors. Langton found a small area conducive to produce CAs capable of [[universal computation]]. At around the same time [[physicist]] [[James P. Crutchfield]] and others used the phrase ''onset of chaos'' to describe more or less the same concept.

== Thank you ==

[[Image:Edge_of_Chaos.png|thumb|Edge of Chaos]]

Thank you for speaking up on the behalf of a user you did not even know. I appreciate your efforts for justice. Should you have any lingering concerns, I encourage you to come to my talk page and join the dialog there on what has occured. Discussion is the best way to calm stormy waters.

In the sciences in general, the phrase has come to refer to a metaphor that some [[physics|physical]], [[biology|biological]], [[economics|economic]] and [[sociology|social]] [[system]]s operate in a region between order and complete [[randomness]] or [[chaos theory|chaos]], where the [[Complexity|complexity]] is maximal.

The generality and significance of the idea, however, has since been called into question by [[Melanie Mitchell]] and others. The phrase has also been borrowed by the business community and is sometimes used inappropriately and in contexts that are far from the original scope of the meaning of the term.

==Ignore all rules==

[[Stuart Kauffman]] has studied [[mathematical model]]s of [[evolution|evolving]] systems in which the rate of evolution is maximized near the edge of chaos.

First, obviously, if rule 5 were deleted, it would become four pillars rather than five. I think that any change to the four/five pillars should be well discussed on its talk page first. Failure to do so would be to ignore all rules, which could be seen as [[WP:POINT]].

I personally think that the five pillars document is fine, because it says that there are no rules other than those listed, and the writers' rules of engagement are one of the pillars. The real problem is that Ignore All Rules is the wrong summary of the guideline, and is sufficiently wrong as to be a destructive title, because it can easily be read as meaning that one can ignore civility.

==Final decision==

Regarding the [http://en.wikipedia.org/w/index.php?title=Wikipedia:Neutral_point_of_view&curid=39805&diff=28415528&oldid=28413773 revert; the claim that all five pillars are unchangeable has no foundation in policy], why is it there then?

I wouldn't know how, but why would you want to anyway? [[User:Bluemoose|Martin]] 14:32, 22 November 2005 (UTC)

:Aha, so you mean find occurances where it was expanded when it used [http://en.wikipedia.org/w/index.php?title=Template:Prettytable&oldid=23029079 this] revision of the prettytable. In which case the only way I think you could find them would be to get someone to use an SQL query on the database dump, but I don't know how successful that would be. At the moment I am not capable of doing this, but plently of other people are. [[User:Bluemoose|Martin]] 16:10, 22 November 2005 (UTC)
