this section makes no sense. does it mean a coin has complexity 1/2 and a system of ten coins has complexity 1/1024?

stuff like this:

"The study of such systems as applied to our universe is in its infancy and speculative in nature, but it appears that there are some low probability systems that are able to sustain themselves through time."

is just philosophizing? perhaps what all this needs is solid external references show a passage in a standard physics textbook to see if physicists think this is a useful concept?

why isn't the wiki on thermodynamic system enough? Wikiskimmer 21:28, 29 June 2007 (UTC)Reply

Also in this section, it's not clear what is meant by "Newtonian ball situation". Is this meant to refer to this sort of system?: https://en.wikipedia.org/wiki/Newton%27s_cradle --Rapidedit1 (talk) 13:56, 24 April 2014 (UTC)Reply

The category:physical systems gives an impresion of what physical systems in general are about. As you can see there, a physical system is an abstraction of all kinds of systems with fysical characteristics. The thermodynamic system is although also an abstrac term, still one of the many physical systems. - Mdd 21:45, 29 June 2007 (UTC)Reply

The reference to Heisenberg's book Physics and Philosophy seems not correct. In his book, he talks about systems of mathematical 'axioms' and 'concepts' to be closed. He is, IMHO, not talking about the boundaries delimited for the study of physical phenomena to which isolated, open an closed system refer to. It maybe the case that Heisenberg does speaks of this classification somewhere else in his book, but certainly not in the page linked in this article.Kakila (talk) 15:49, 11 August 2011 (UTC)Reply
