extending the framework from the city to the society

Understanding living things can be hard. Sometimes things that don't appear to be living can be.

summary


In this post I will argue why we should consider large bureaucracy and corporation as actually living things. They are not actually made of the same stuff that we are familiar with living things being made of, but they are none the less alive. I think its important to understand these creatures, grasp how they perceive the world and perhaps then we can begin understand their cognition.

introduction


I have often argued that people are unable to comprehend what they can't see. We build a variety of tools to enable us to see into things which are beyond our ability for observation in part to allow us to see and understand more.

Microscopes are a good example of this principle. Before we were able to observe the microscopic we had no idea what were bacteria or how much of what modern medicine is built upon worked or that it even existed.

In my blog I occasionally make reference to a concept that I call "The Machine". In this article I will attempt to explain what this concept is. The Machine is not just a mechanism, The Machine is actually a kind of living organism but one which certainly not entirely organic and transcends a couple of layers of conceptuality. This is what makes the concept difficult to grasp and for many it will seem just some sort of fancy.

So what is a living thing? Seems at first like an easy task to identify that which is living and that which is not. I would like to venture a definition; I think that anything which can:
  • make an observable change on the world
  • reproduce
  • make a decision
  • die
is a living thing. Seems pretty obvious, but perhaps many will struggle against this definition set when I apply it in a moment.

How often have you heard some politician or company director or person employed in some role in a company, say
"I didn't want to do it, but I had no other choice in my role"
Quite often I'm sure.

People have struggled for as long as we have written records (and probably longer) to understand what is it that makes a person or an animal alive. The various sciences have grappled with the question and we have uncovered many things about the nature of the bodies of living things to expand our understandings. While we understand much about biology, biochemistry, anatomy and even the electro-chemistry of nerves we just don't know why people are alive or why they die.

In this essay I would like to turn the question around, instead of looking at us I'd like to look at things outside of us, things we can't see but yet like the common cold know exists. We often call then systems.

Lets start with a system called Government.

Once upon a time in history we were manged in less complex groups and had a person who was our leader. We might call this person a King. Eventually the area of power under the control of a King grew too large and he called upon others to administer his authority for him.

This can become so large as to overwhelm the King and others in the system that the King has created. Eventually those who the King gave power to realise that they command more power than the King. So when something occurs to give them reason they can challenge his authority and even wrest power from the King.

Since I'm Australian and since Australian government derives its existence from the English government I thought I'd examine the this history (not because its special in any particular way).

In 1215 members of the King of Englands system Barons rebelled against him and forced him to sign the Magna Carta. This essentially took power from him and imposed a codified system of written ideas called laws.

These laws removed his power to act in any way that he wished and imposed upon him punishments (punishments upon the King!) if he resisted these laws.
a committee of 25 barons who could at any time meet and overrule the will of the King if he defied the provisions of the Charter, seizing his castles and possessions if it was considered necessary(wikipedia).
So for the first time in English history the King, the person who ruled the land according to his will, was subjugated to rules written on paper.

I would guess at this point that some are saying: But these are just rules, just writing, they are not living, they are not something which can constitute as a living thing.

This is true, they are just a set of rules. But then so too are all the chemical reactions which define how our bodies work. These rules of chemistry and physics can also be used and manipulated to effect us and our thinking. Anti depressant drugs are a good example of this.

Lets consider a system with some very simple rules. Imagine a checker board for a game, but one which only has white squares. The rules of our game are simple,

  1. if a checker exists on our board then that square is "alive" and if no checker is on a square then that is "dead"
  2. Any live square with fewer than two live neighbours dies, as if caused by under-population.
  3. Any live square with two or three live neighbours lives on to the next generation.
  4. Any live square with more than three live neighbours dies, as if by overcrowding.
  5. Any dead square with exactly three live neighbours becomes a live square.

This is essentially the rules of the game called Life by John Conway. It seems very simple, just a set of rules or laws governing what happens to the checkers. It also defines a method of spawning new life and a circumstance where death occurs.

gliderYet from this simplicity of rules comes something which if we represent it as it moves through time we see something amazing. Sometimes things seem to be alive, like the walker represented here to the left.

The graphic at left is an example of stepping though these rules and showing how this "thing" moves across the board in a simple movement behavior. Sure, its not living, perhaps its not even real ... but then when you look at the biochemistry of just one part of your body (say insulin production) that doesn't look alive either.

The same set of rules with enough pieces to act upon can make amazing things. For example:

this combination of rules and its effect on the pieces creates a system which is self perpetuating and grows forever.

So is this a machine? Well classically we call things made of metal that use energy and go round and round machines. Stuff like this classical representation of a 4 stroke engine. It used to be harder to think of a machine as being something just composed of rules.

It is in fact exactly that when you look at it from an engineering or scientific perspective. The engine is a collection of the rules of thermodynamics, chemistry and physics.

By applying these rules (collecting things together in the correct manner) we can create a machine.

Since the advent of computers it becomes perhaps easier to understand that a system can in fact be just a collection of rules, after all programing languages are actually just descriptions of what to do and what decisions to make.

Clearly computer programs require computers to operate them and equally our government system requires humans to execute the instructions and do the tasks.

So people have become the base hardware for the machine which we run and execute.

If this sounds like something out of the matrix, or something out of fiction which could not be possible; ask yourself this question:
Can you imagine a person doing something that that don't want to do but have to do it because its their job and that they are compelled to do this by law?

so what about reproduction?



gliderWell consider that the English Government started colonies in Australia, when on 13 May, 1787, the First Fleet of 11 ships set sail for Botany Bay. They intended to establish a colony. That would require governance and that governance was clearly going to be modeled on that of England. The English government had successfully spawned a child. This child then became children with the creation of additional colonies of New South Wales, Victoria and so on.

Eventually some years later these colonies consider unification and the creation of a new governing body; the Federal Government was spawned in 1901.

When it comes to rules for the system to have complex morphology have a look at the list of legislations below, each one of them being far more complex in nature than the simple 5 rules which defined the operation of the "Life" simulation above.

If Government is a living thing then clearly Government is a very complex living thing.

It is not however only Governments which can be considered as living things. Companies too (especially under corporate law) are legal entities; they hold property, employ people, and make decisions.

So it would seem that we already have in our midst an organism which lives, yet does not breath and can not be easily touched. It shapes our lives and controls us in ways which expand with the rules which it creates.

If you doubt this then consider this article in a UK news paper where a child is accused of being racist by calling a boy ‘broccoli head’ and another was said to be homophobic for telling a teacher ‘this work is gay’. The article goes on to mention:
Schools are forced to report the language to education authorities, which keep a register of incidents.

and that
In total, 34,000 nursery, primary and secondary pupils were effectively classed as bigots because of anti-bullying rules.

The school can keep the pupil’s name and ‘crime’ on file. The record can be passed from primaries to secondaries or when a pupil moves between schools.

And if schools are asked for a pupil reference by a future employer or a university, the record could be used as the basis for it, meaning the pettiest of incidents has the potential to blight a child for life.

This does not sound like the sort of reaction a human would have on how to treat their kids but yet this is the reaction that the machine has for sorting us out.

What about this? It sounds more like a system protecting its component parts rather than something designed to look after humans.


I believe that there are far more examples and comparisons I could make to support my argument that Government and Corporations are actually living things, but rather than do that I'll leave you with a couple questions.

How do you negociate with such a machine?
Will it listen to you?
and can it be directed by human will?

holding the system responsible or even punishment of the system


If we decide that we don't like the party in control of government and we vote them out, does that change the machinery of government or just put it on a different PC?

As it stands at the moment we have very little understanding of this life form. We as yet are perhaps uncertain that it is a living thing, but make no mistake this thing can control our lives, alter the environment and exert influence.

The simple rule based system above called 'life' created stuff not so much different to observing bacteria growth, look again at the list of rules below which form our Acts of Law in Australia and tell me that does not form the basis for even more complex interactions. Combined with the execution on the human computing platform I think its almost certain we have something alive here.

other paradigms

Urban Metabolism has been used by other Authors to assist in the conceptualization of a topic using the metabolic framework as a metaphor. Gandy for instance took a non-functionalist approach to this in his work.

I was thinking earlier today that other such metaphors can be substantial aids to other concepts,for example;

if we regard a city as a complex multi cellular organism, then a possible view of this is that particular roles within the city can be compared to metabolic pathways or even organs.

More complex organisms take advantage of cognition to advance their possibility for success in life. The less complex animals regularly differentiate food from toxins, remember where food and water is and as complexity evolves develop methods specific to hunting particular prey or remembering where food is.

This can be applied to the human situation and to the city.

Clearly the city needs to optimize itself and to adapt to changes, both environmental and those which result from the reorganization or growth of its population.

But does the city always make ideal choices?

Town planning for instance relies on many complex determinations and regulations. These are no different to the rules which govern any chemical reaction. However more than regulation is required as the rules in managing a complex environment outstrip the ability of codification.

I would argue that this is why complex organisms developed cognition.

The city has at its disposal cognitive ability in that the components of the city are actually humans. To be effective this cognition requires memory, and this is something which at the moment is present only in people.

This means that effective use of cognition in the city requires that many of the people who make decisions and determine policy need to have not only knowledge but memory: meaning they have had to work in that role for some decades.

An excellent example of this comes to mind in the damage occurring in Queensland due to flooding at the moment. Much of this damage is occurring due to changes in zoning of areas from flood prone to not flood prone. While in the previous 15 years flooding did not occur, in the previous 30 it did. Those with experience would know that.

energy flows in the city

identification of a problem


Energy is perhaps one of the most critically significant aspects of metabolism, the simplistic view of food = energy misses the point on how that energy is generated and transported.

While many animals put food into their mouth and digest it in their intestinal tract its is not just the end of the story. If we think of both kinetic and potential energy then chemistry contains potential energy and things like muscles turn that into kinetic energy and places like the brain and neural systems use that potential energy for other processes.

So while energy is perhaps centrally generated (by the gut) it is distributed to locations and then converted locally on demand.

I've been thinking of writing about this topic for a while, but last night I happened to be watching a BBC programe called "Britan from above". This went a little into depth about the issues of managing loads and demands on the electrical system. Starting with an overview of the City of London, they observed all the patterns of activity from the air and remarked how much like a machine it was to observe the way millions of people went about their daily lives "on that tiny island". It immediately piqued my Urban Metabolism mind as being exactly a good description base.

As night fell on the city they rose to altitude to see the network of lights and started to consider the generatoin of electricity. From here they cut to an interview with the senior electrical controller of the UK's electrical grid, where they discussed the nightly ebb and flow of electrical demands within the UK.

This was simply a stunning display of what is wrong with our fundamental paradigm of energy generation and distribution.

Simon (as he was named) sat with a TV on tuned into the "East Enders" waiting for the end of the program so that he could cue in massive additions to available the power grid to cope with peaks in demand of 600 mega watts occurring just because everyone would get up and put the kettle on.

He pulled in power from several hydro electric systems all cued to suddenly inject massive amounts of power into the grid (potentially frying it if not balanced) and even had to pull power from generators in France.

A stunning display of the effects of distributed but synchronised demands.

Imagine for example you're talking on the phone and walking across the road on the phone and suddenly "Bwaaaaaa" a bus blows its horn and you realise "shit, there's a bus coming straight at me"

You suddenly put everything you've got and lurch out of the way. In that instant you drew together almost every muscle you had and pulled quite a peak demand on your system.

You didn't need to cue in power from the bloke next to you, so clearly you're managing your energy much better than the urban metabolism is presently.

the natural solution



So how do we do it ... I mean as metabolic organisms we can't just pull power from external sources when we suddenly need to call upon every muscle of our body. Lets go back to look at our metabolism and we see that while we get energy from consuming food, we transport that energy to be stored in locations (or reservoirs) like fat and perhaps less obviously in blood sugar and Glycogen.

This blood sugar is the energy reserve which is called upon to provide the muscles with the energy (ATP) they need for providing the kinetic energy. There is even a mechanism (the Mitochondria) to keep this going well past the point where Oxygen is available in the system.

This system (unlike the electrical grid) decouples conversion of the energy resource (food for us or coal for the power station) from the delivery of energy at the site. I think its fair to say that almost all organisms from the simplest single cell organisms through to mammals follow this strategy.

solutions suggested by this analysis


For our city, electricity (not APT) is the currency of energy. We convert the chemical energy stored in our fuels using a chemical process (burning), a nuclear process (using thermal capture and steam to make the conversion) or even capture of kinetic energy in the form of hydro electrical generation. What ever way we use we get our energy as electricity there. From there we distribute it to the homes or businesses (the cells) via a network.

Economies of scale mean that its better to make the conversion to electricity in the power station and transport it to us, so learly what we need to do is store that energy to use it when we need it not just when its made.

A quick review of the electrical industry will soon reveal that its not a problem to generate the average amounts of energy we need, its just dealing with the spikes which is the problem. Some sort of reservoir of energy at our homes would be ideal.

Well, that doesn't take much thinking as we have had rechargable batteries for well over a century. These can provide both deep cycling (long discharge) and support many cycles of charge and discharge.

A system like this takes (say) 5% of your maximum demand all the time and provides the extra resources of energy for the shorter times when you actually need them. Times like:
  • when the lights are all turned on around the town as people wake up to go to work,
  • when the fridge motor kicks in to start cooling down your fridge
  • when you start cooking dinner or boiling the jug (if you aren't diversifying your energy already by using Gas that is...)
This technology is essentially the same as a UPS or that which is used to store the output of a solar power system would, when connected to the grid, essentially:
  • take 90% of the fluctuations out of the system,
  • make management and planning of the infrastructure easier
  • be more compact and cheaper than those used in Solar Electrical Systems (because they could be trickle charged all the time)
Considering that many power companies actually sell "off peak" electricity at much lower than normal rates anyway, although this is so far aimed at just electrical hot water systems.

This also brings with it an added benefits of;
  • security: whole regions could be 'blacked out' without impact for short time and damage to the grid would not be as catastrophic
  • capacity building: enhanced knowledge and awareness of power usage by each householder will likely result in more interest / knowledge in efficient behavior
  • economic benefits: a more distributed "power economy" would also result in the generation of some new long term jobs perhaps in the maintenance of home storage systems

I'm actually surprised that people are not thinking of doing this already ...

initial questions

One of the first things which comes to my mind is what will be the issues with storage cells, their lifecycle and disposal?
