I'm not sure why you say this is the reverse of emergence. I lost you there. Also as for when something is a something - it is when an observer says there is a something.

>I am miffed that nobody rose to the bait of my question about when is a something a something. What's that I see...a wiggly worm...mmm, tasty... Ok, I'll bite. :-) Something is more of a thing when it has an identifiable function. I would say hurricanes are emergent self-organizing structures of matter that dissipate an energy gradient (vertical difference in air temperature). As gradient dissipators, hurricanes serve a function and are things. (I suspect you knew I would say some such thing) I tend to be more interested in self-organization than emergence only because I think I can get more of a useful handle on the term. It's a working hypothesis that all self-organizing systems do work. With hurricanes I think one might be able to measure the amount of work performed by/on the system and ask if the constraints in the system that allow work to be performed are context-sensitive or context-free. The constraints of the work cycle(s) within a hurricane that result in lost degrees of freedom on the air molecules are context-sensitive. If you removed the nonequilibrium context driving the individual air molecules of a hurricane, the system would lose its emergent function as a gradient dissipator and become an inert concretion. By contrast, if the constraints of any given system are context-free the system might still do work (as a car engine does) but would not be of the self-organizing or emergent type. As for emergence and hurricanes, I think emergence lacks a universal definition at this point. (I tend to conflate it with spontaneous symmetry breaking). You might be interested one of Russ Abott's very readable papers on the subject: http://abbott.calstatela.edu/PapersAndTalks/Emergence%20Explained.pdf Or Cosma's blurb: where he makes a distinction between emergence and self-org http://cscs.umich.edu/~crshalizi/notebooks/self-organization.html http://cscs.umich.edu/~crshalizi/notebooks/emergent-properties.html Or, Jochen's: http://arxiv.org/ftp/nlin/papers/0506/0506028.pdf Please don't stay miffed, Nick :-) -Steve -----Original Message----- From: Nicholas Thompson [mailto:[hidden email]] Sent: Monday, September 26, 2005 7:35 PM To: Friam Cc: Jaan Valsiner Subject: [FRIAM] miffed All -- I am miffed that nobody rose to the bait of my question about when is a something a something.

Nick, I must admit I did not understand your mail completely, but I just learned four new English words: "to miff", "bait", "concretion" and "precipitation". Thanks :-) It may seem inappropriate to discuss the question if hurricanes are things in the light of the recent events, since they have caused so much trouble, anger and suffering. Nevertheless, I think it is interesting that hurricanes get names, although they are non-permanent, volatile and temporary dynamic phenomena. A hurricane is a dynamic weather phenomenon which consists of strong winds that rotate constantly around the center of a low-pressure area. Since hurricanes get names, they can be seen as things. Is wind a "thing"? Is a storm a "thing"? I would say yes, because they are persisting patterns in a dynamic system. http://www.google.com/search?q=define:+Hurricane You do not need agent-based modelling to describe hurricanes. Ordinary differential equations will do. In this sense, they are more "physical" than "social" phenomena, similar to the critical points and avalanches in self-organized criticality or phase transitions in physics. Every dynamic phenomena in a dynamical system - fixed points, critical points, saddle nodes, limit cycles and attractors - can in principle be described as a form of simple "emergence". The form of a hurricane resembles an attractive fixed point in form of a whirl, vortex or spiral. It can be described by a simple linear and two-dimensional differential equation, which has a pair of conjugated complex eigenvalues with negative real part. What all these phenomena have in common is some form of stability in instability, permanence in change, or persistence in dynamics. The critical point in self-organized criticality is characterized by stability in instability, too: the system evolves always automatically to a certain point (for example the critical slope of the sandpile, which is also called "edge of chaos" sometimes) and is therefore stable, but at this point all kinds of avalanches and cascades can occur, and therefore the system is at the same time instable. By the way, hurricanes and galaxies show surprising and interesting similarities. As Eric J. Chaisson says in his book "Cosmic Evolution" (Harvard University Press, 2001): "Interestingly enough, the pancake shape, the spiral-arm structure, the distribution of energy, the differential rotation pattern, and many other morphological characteristics of hurricanes bear an uncanny resemblance to those of spiral galaxies [..] even the "eye" in a hurricane conjures up the purported "hole" (black or otherwise) in the cores of most galaxies.", see http://www.vs.uni-kassel.de/~fromm/Hurricanes.htm -J. |

How right you are.. This reminds me of Blaise Pascal and his thoughts about consciousness: "When I consider the short duration of my life, swallowed up in the eternity before and after, the little space which I fill, and even can see, engulfed in the infinite immensity of spaces whereof I know nothing and which know nothing of me, I am frightened, and am astonished at being here rather than there; for there is no reason why here rather than there, why now rather than then. Who has put me here? By whose order and direction have this place and time been allotted to me? The eternal silence of these infinite spaces frightens me." "What is man in nature? Nothing in relation to the infinite, all in relation to nothing, a mean between nothing and everything." and perhaps of Buddha, who has taught that we can find our true self if we extinguish all thinking and finally ourselves completely in the Nirvana (if the soul does not exist at all and the mind is only an "emergent" dynamic phenomenon of myriads of neurons, then he is probably right): "All things appear and disappear because of the concurrence of causes and conditions. Nothing ever exists entirely alone; everything is in relation to everything else. " "Everything is changeable, everything appears and disappears; there is no blissful peace until one passes beyond the agony of life and death." -J. -----Urspr?ngliche Nachricht----- Von: Friam-bounces at redfish.com [mailto:Friam-bounces at redfish.com] Im Auftrag von Robert Holmes Gesendet: Dienstag, 27.

I think what makes a thing a thing is a profound question. There are
many ways to see it. One is a kind of functional emergence--when it makes interaction and dynamics easier to describe by the people doing the describing. A kind of informational compression, a more complex analogy of why statistics is useful--mean and variance are handy compact descriptors of large amounts of data, but they are not "things" in any objective sense, not a Ding an sich as Kant would have it. I'm not sure anything is a Ding an sich, but that's a much longer conversation.

There was an interesting article in the NY Science Times:
http://www.nytimes.com/2005/09/27/science/earth/27loop.html which you might be able to see. The article discusses the dimension of subsea energy and the depth of warm water needed. So it also depends on subsea counterpart(s) - the loop - and other 'things' which should be considered as the storm makes it's way across our oceans?
