NJournal Notes 7.0 The @ symbol and buckminsterfullerene (C60)

Yesterday I discovered a chemical notation that was new to me. It point to a way to construct a simple sentence that communicates the complex adaptive system characteristic of levels.


This morning there was an exchange on Face Book that gives a sense of where I'm going with this.

I wrote a concept piece some time ago about the fabric of life:
"I once saw a documentary about a pygmy hunter. He had an opportunity to kill a forest giraffe but he let it go. He said he let it pass because killing it would leave a hole in the forest. 
After many years of thinking about and working with the relationships that make up our lives, I think I am beginning to understand in the way that wise pygmy hunters understand. The life in a place is a fabric. It comes in up to seven layers that we read about in the permaculture literature (plus the ones under water). It involves threads from all five kingdoms of life that we read about in the ZERI literature (Zero Emissions Research Initiative) 
When this fabric is thickly interwoven with all five threads in all seven layers we feel whole and call it beautiful. When this fabric becomes thread bare we suffer from the absence of its shelter. The fabric is made up from the participation of individual living things – in what biologists call the food web. We participate like all other living things. We are only different in the power we hold to tear holes in the fabric – or to use that same power to enhance the weave. 
The message from Permaculture and ZERI, and all the other organizations experimenting with the relationships that make up our lives, is that saving the world will not come about through political action (although that can be helpful). Government has its own specific role in the fabric. We will save the world by learning to enhance the weave of the fabric of life - in the place where we live."
You can find my response and follow the ongoing  conversation at David's FB thread 


The @ symbol 

The @ symbol (at sign) indicates an atom or molecule trapped inside a cage but not chemically bound to it. For example, a buckminsterfullerene (C60) with an atom (M) would simply be represented as MC60 regardless of whether M was inside the fullerene without chemical bonding or outside, bound to one of the carbon atoms. Using the @ symbol, this would be denoted M@C60 if M was inside the carbon network. A non-fullerene example is [As@Ni12As20]3−, an ion in which one As atom is trapped in a cage formed by the other 32 atoms.

In general form the @ symbol would allow us to write  nP @nStn@nTun Since the notation is content and context agnostic, it can be used to write simple sentences about any living system ( complex adaptive system.) 

Two examples of use in specific contexts. In the context of permaculture we can write Individual @bioregion @biosphere.

In the context of education systems in the United States we can say student @classroom @school @district @state department of education @national department of education @national government

  1. Michael, are you saying the layers of the fabric are like the nested @s? I don't understand why you've chosen the buckminsterfullerene cage with the atom or molecule trapped inside, yet not chemically bound, as an example of nestedness. Aren't the dynamics of CAS, as described by David's permaculture exaple, involve relationships that link the inner and outer? Or maybe the buckminsterfullerene cage has a relationship to what's inside and you are aware of some significance to space in-between of which I'm not aware.

    I think what is missing here are the connections between the inner nPlex to external nShapes (@s) via actions (nEx) that reveal the relationships.

  3. Daniel,
    I just using the notation @. the rest of the model is suboptimal as you suggest. My thinking at that moment is the best thought model is going to something like Tensegrity Icosahedron. I have a feeling strings will be the like the cytoskeleton that came up in a conversation this week. It's going to be something about how different tension on the strings the shape of the icosehedron. Then we put in the external interactions with other icosehedrons through strings coming from the outside.

    Still mulling. I can use whatever help I can get..:-)

  4. Mesmerized article written on this blog with other relevant information. It is straight to the point that how we can improve our skills as well as how we can be represented to a new stream of professionalism.
