this page is confusing. it contradicts itself all over the place.

1. it says schrodinger used the term negative entropy, and brillouin used the term negentropy later. then later it says 'by using the term "Negentropy", [schroedinger] could....'

2. it says "negentropy is a misconception...", then it goes on to explain the technical meaning of negentropy. if it's a misconception, exactly what is it explaining, or where is the misconception? (did he mean it's merely a misnomer?)

4. it's not clear what schodinger is saying in the quote.. what's described above is NOT free energy, but the quote seems to be implying that schodinger thought life is free energy.. i'm sure he was smarter than that, but then, what the heck was he saying?

(i'd also like to know if the thermodynamic description of negentropy and the information-theoretic description of negentropy are isomorphic.)

I think that this article should be merged into syntropy.

Nonsense

This page is complete nonsense. The author obviously has no idea about random variables, densities.

If you are looking for more information . . .

I read this article as a supplement to what I was studying in a college course, and as was pointed out in the previous posts, it is much too confusing to be of any use. The author seems to think that negative entropy only refers to living systems and not systems in general. If there are those looking for a better explanation of what entropy and negative entropy are look in Organizational Communication: Foundations, Challenges, and Misunderstandings second edition by Modaff, DeWine, and Butler. The section you want is in Chapter 4 (Systems Theory) on page 73. It is a college text book so I do not know how difficult it is to find, but it is a great resource if you are looking into something other then biological systems in the application of the term negentropy. 71.191.23.120 (talk) 21:13, 9 December 2008 (UTC)[reply]

Term is incorrect

Coining an antonym by adding the prefix 'neg' to it makes no sense grammatically. First of all entropy is a scalar: It has no direction and hence is not positive. Secondly, in english the correct rendering of such a prefix would be anentropy (like aerobic/anaerobic). You might as well say something was negpossible, negimagineable or negsensical. Article should be permanently deleted along with any reference to it. —Preceding unsigned comment added by 114.77.66.225 (talk) 04:42, 14 August 2009 (UTC)[reply]

Network entropy

What is "Network entropy"? I cannot find it in the work of P. Comon, as cited. —Preceding unsigned comment added by 161.53.64.104 (talk) 12:32, 18 January 2010 (UTC)[reply]

relation to Gibbs free energy

Learning about entropy, and the thermodynamic law that any entropy decrease is offset by entropy increase (such as heat energy) of the surroundings I came to understand syntropy as the local decrease in entropy minus the 'generation' of entropy, or the sum total of entropy increase in the system and surroundings. While the magnitude of this may be Helmholz free energy (related to Gibbs free energy) I may define syntropy as its derivative (i.e. how fast it changes over time). Is that definition ever used? 24.184.234.24 (talk) 04:30, 1 October 2010 (UTC)LeucineZipper[reply]
