Do you really know what’s happening around you?

Thursday, March 22nd, 2012

The interesting thing about reality is that we don’t notice it until after it has happened, if we notice it at all. At a fundamental level we are experiencing the world as a flow of environmental data; things happen and register with our nervous system through our senses. And, we notice.

Or do we?

The interesting thing about reality is that we don’t notice it until after it has happened. Each sense is processing a constant stream of stimulus, whether we notice it or not. And, it’s all competing to be noticed by our consciousness. Most of it simply passes us by, as if it didn’t happen, but a small amount of it bubbles through our thoughts and awarenesses to cause us to direct our attention. By the time we do, the original event registered by our senses has gone, and been replaced by whatever is happening now.

The interesting thing about reality is that we sometimes don’t notice it at all. A sensation bubbles through our nervous system and we become conscious of it, and then we notice what it means; a sound becomes a plane passing overhead, and we no longer notice the sound just the plane; the sensation in our stomach becomes our hunger, and we only notice the hunger not the muscular tension. The colour, texture and sound in front of me becomes you, and I no longer notice the individual sense data that makes you up, I just notice something that I call you. I stop paying attention to what is going on, and instead pay attention to the abstraction of it, and in that moment I can cease to notice when you do something subtly different from what I expected you to do.

We mostly don’t notice what’s going on in the world, instead we notice what we notice about what’s going on, and then act as if that is what is going on. We replace reality with our model of reality, and reality as it is actually happening fades into the background. Once something has a meaning, that meaning replaces the something, and the raw something ceases to exist.

This has a profound impact on the way that we respond to each other in environments where feedback defines how we work and what are are doing.  Are we responding to what is actually happening, or what we think is happening? How does someone respond to our response, do they respond to what we are doing, or what they think that we are doing?

How often do you notice that the person talking to you was actually talking about something other than what you thought they were? If the answer is rarely, then I suggest you stop and actually pay attention to what’s really going on around you. Do you notice reality as it actually is, or could be that you’ve been paying attention to your imagination instead?

Stop Stealing Dreams

Wednesday, March 7th, 2012

Seth Godin is a leading voice in area of marketing. He write a daily blog with has a huge following, and has written several books. His main viewpoint is that the social contract that brought the mass market into existence had a key component around the construction of schools and education for all. The factory owners not only needed a market for the product that the industrial revolution made possible, but they needed a supply of workers educated sufficiently to enable them to be good factory operators.

The world we live in today is no longer that world. The manufacturing sector has disappeared and we no longer need to educate our kids with the knowledge that they will need for a factory job. In fact, the social contract said give us your kids and we will train them and guarantee them a job. They will then have income and also become our customers. And, you will gain by having product available and an improved standard of living.

The world in which those rules were made, and the world we live in today have diverged, but the structure of education hasn’t. It still compulsory and we are teaching our kids and preparing them for a world that no longer exists. We are lying to them.

Seth has just finished writing a manifesto on education: Stop Stealing Dreams. Please take a few minutes and take a look, and share your comments with me. What are we going to do about it?

Beginning to think about feedback in agile software development

I thought that as an exercise it would be interesting to explore in a series of small blog entries the nature of feedback in dynamical systems, and the implications that that has for an agile delivery methodology. So, stay tuned if you’re interested, as that’s what I’ll attempt to do over the next few days and weeks. Feel free to chime in, so I’m not just talking to myself :).

Seeing things again, as they really are.

Monday, January 9th, 2012

The moon has always been a flat disc, invariably waxing and waning through the illustrations in the story books of my youth. And, so as I grew up, that’s how I saw it – up in the sky, a mixture of bright light and silhouette, mysterious but unquestionably there.

I’m not sure when I became aware that the moon was a ball, in strange oscillation around our home planet. I think that that was from an early age too, when for me the solar system was first full of planets and lumps of rocks. But all I saw when I looked up as a child was the stars and a slice of the moon looking down on me in the night.

Suddenly, I remember when as a teenager it happened; the first time I looked at the moon and a voice in my head revealed in context, “that’s not a shape, that’s a volume!” And instantaneously, I became aware of the enormity of a massive orb encircling in the night sky. A thin slither of light highlighting a mostly dark, invisible globe, hiding in plain sight. The surprise of it still lives me with today, how something so old and familiar can suddenly become new and mysterious again.

Today as dusk threatens to break, I see my friend the moon again. This time it has a companion, a small bright star to keep it company; the only star in the sky. As a child I saw all points of light as stars, but this one is Jupiter; our humble moon and a majestic planet, owning the sky. Only now am I becoming aware that I have been looking at the planets all along, not all stars are stars, and what I thought was hidden was hidden in plain sight.

It is easy to get lost in the familiar and well known, the well heeled grooves of life. We take our relationship to the things in the world for granted, and over time they become comfortable and unchanging; we never think to question them or notice whether our ideas about them need updating. The same is true of our relationships with each other. Most individuals that we meet are pigeonholed into some category or other, after a very short time in their presence, and it is then subsequently very rare for a relationship to change dramatically, and for two individuals to get to know each other again as if for the first time.

I am reminded as I recall this childhood incident that it’s even possible for the most fundamental things, to become more than they were. That, quite literally, as sure that I am of what is real and what it means, I must hold open the possibility that at some level my working assumptions are wrong, and some deeper truth and understanding could be revealed to me.

As I find myself entering this new year, full of awareness that not so far beneath the surface of what I take for granted are relationships and inspirations staring me in the face but not previously seen, and I ponder on which of these will reveal themselves first.

On technology, time machines, and imagination

Thursday, October 6th, 2011

A long long time ago, when the land was owned by dinosaurs and man had not started breathing yet, times were simpler. There were no mobile phones or computers, no lasers or global positioning satellites, no steam engines, cars, planes, clocks, radios, toaster waffles.

But here’s a profound thought: our understanding of physics tells us that the Laws are Nature immutable; they’ve been the same since the Universe began (or forever, if you believe that it’s always just been). That means that any of our magical and revolutionary devices that we’ve invented today with our clever modern know-how would have just as easily worked back in time, millions of years ago, aeons before they were conceived.

Imagine then that we have a time machine (probably a Tardis, so that it’s big enough on the inside to hold all our junk). We could load it up with radio towers, diesel and generators, and a load of mobile phones, and take them on a ride back in time. Set it all up and switch it on, and it would work! We’d be able to make phone calls, and sell monthly contracts to tyrannosaurs so that they could keep in touch with the Daily Fossil!

Why is this exciting, I guess you are asking? Hmm indeed.

Well, project yourself now to the future, the distant future, maybe over 10,000 years from now. It’s plausible to expect that we would have solved many mysteries. We’ll know what dark energy is, and dark matter too, and the Universe will be our slave. We’ll have discovered new phenomena, and developed new technologies and materials; our clothes will all have nano-scale detailing and we’ll all drive around in vehicles with the new Ubbba-Drive-4S, powered by our own sense of satisfaction.

So then, what if one of our future selves dives into their Tardis-4S, packed with goodies, and descends on our timeline? Arthur C. Clarke said that any sufficiently advanced technology would be indistinguishable from magic, and so it would seem when your future-ganger switches on their 4D-Quanta-Viddy and holograms of yourself from all the adjacent parallel realities appear instantaneously beside you. Magic indeed!

But the point is that their technological toys would work in the here and now, rather nicely too. (Just imagine how much you could flog them for on E-Bay!) That is to say, that the only reason that we don’t have such miraculous faculties available to us today is not because the Universe doesn’t support such nonsense, but because no one has thought of it yet! It’s a limitation of our imaginations, not a limit of nature.

It is possible for someone, right here right now, to invent some amazing technology so amazing that we would not recognise it in relation to the world that we already understand. And the only thing stopping us from conceiving of such things is our imagination, and the limitations that we hold in place that prevent us from seeing and understanding the possibilities that are potentialities in the system that are available to be harnessed.

So, how do you relate to the possibilities that are available to you right now? My point is that there are known possibilities and unknown possibilities (apologies to Rumsfeld). Unless you hold a space available in your imagination for the unknown ones you might never genuinely do anything that will surprise you, or astonish you, and the world will never benefit from that wonderful thing that only you could give birth to.

A few conversations….

Friday, September 30th, 2011

It’s not unusual for me to have extensive conversations with strangers. These days I’m spending a lot of time on trains, and have a lot of opportunity to partake of the company of many an interesting person.

In recent days, as well as the usual banter and jokes with the ticket staff, and random quips with fellow table sharers, I’ve managed to get myself embroiled in deep conversations about the design and influence of every day objects (with a marketing guru); the nature of the education in the school system, how it was constructed to prevent free thinking individuals and how the government is unable to redesign it in terms of its historical context (with a regional school coordinator); and the nature of consciousness, how it is affected by lack of sleep, and how everyday reality is shaped by random events and the attitude you have as you make your self present to it (mostly with myself.)

A take on the the faster-than-light neutrinos, and the cracks in our understanding of nature.

Wednesday, September 28th, 2011

A recent report in the news indicated excitement about the suggestion that neutrinos had been found at Cern travelling faster than the speed of light. One of possible explanations put forward was that maybe the neutrinos were tunnelling through some extra dimension.

The statement was made in the content of quantum field theory and what is called the Standard Model of Particle Physics. This is an empirical model which condenses our best understanding of nature yet, describing all of the known sub-atomic particles in nature, along with all the known forces which govern their interactions.

However, the Standard Model isn’t exact. It contains 18 free parameters which need to be fine-tuned by experiment in order for the equations to be predictive. Many experiments have been run to measure what these values should be, and the result is that the theory now predicts the results of all the particle physics experiments that we can conduct to the highest precision of any prediction that we have ever made. Even so, we can’t get away from the fact that we had to set these “constants” by hand, and that means that although the theory can describe what we observe, it fails to explain why.

Theoretical physicists continue to invent new models, searching for a mathematical structure which could hope to explain the nature of the free parameters, and try constrain their values. It’s here that ideas like String Theory and Super-Symmetry originated, and the whole idea that the Universe might consist of not just 3 space and 1 time dimension but extra spacial dimensions; 6 or 7, or even 22 in some String theories. These extra dimensions appear as a side-effect of the condition that models must be mathematically consistent, and describe matter that behaves compatibly with existing observations. Therefore if we believe that this new maths in some way describe reality, we must also try and understand how it is that the extra dimensions exist physically.

It’s in this context that the idea that these neutrinos might be extra-dimensional travellers originates from. Arguably, one of the research goals of the experiments taking place at Cern is to try and find ways of probing for a “signal” that these extra-dimensions exist, so that we can prove or disprove the models that predict them. So, if more interesting events emerge you should expect to hear more of these kinds of sound bites in the news.

But, before we get carried away, there already exist gaps in our understanding of neutrinos without any need for extra dimensions. We’ve recently discovered that the three different kinds of neutrino transmute into and out of each each other as they travel through space-time, and have what is described as a “flavour changing symmetry” that wasn’t previously known. We don’t know why that happens, but now that we know it does we’ve had to extend the Standard Model to include it as an ad-hoc extension. This adds another 7 free parameters that also need to be fine-tuned.

This brings the quantity of variables in our “vanilla model” that are needed to explain why the Universe behaves the way it does, to a staggering 25. Each one has to take a very precise number, which if it varied by the smallest amount the entire Universe as we know it would not be possible! That’s a lot of extra dimensions to come to terms with, before we even start to consider the addition of extra spacial ones.

There are also other holes in our knowledge which are revealed when our best theories are used to try and explain the information returned to us from the high precision measuring devices which we have pointed out into the Cosmos. These holes are currently labelled Dark Energy and Dark Matter, and their explanation is occupying some of the brightest minds on the planet. Some of the most advanced particle physics experiments at Cern have been constructed in the hope that they might hope to explain these cosmological quandaries, by testing new theoretical models and also, of course, trying to find the biggest hole of all: a predicted piece of the Standard Model call the Higgs field, and better known in the media as the so called “God” particle.

No-one can really put their hand on their hearts and say that they understand why the symmetries in the Standard Model have to be the way that they are. That’s why so much work has been put into String Theory and Super-Symmetry, which are really just wild stabs at trying to find some mathematical structure which would incorporate all the symmetries that we find in nature, and constraining the free parameters (or at least reducing the quantity of them!) And, let’s not talk about the Higgs! If it turns out not to be found experimentally (and we’ve been looking for it for years), then the whole thing falls flat on its face, and we have to return to the drawing board altogether and have a big re-think. It’s not looking good for the Higgs, so far.

Now, I’m not saying that this is in anyway an explanation for neutrinos potentially travelling faster than light. If that result is confirmed, it will definitely turn things on their heads. But, unlike almost all of the physicists that I know, I don’t think that we’re anywhere close with the current models that we have. At best the Standard Model is a toy model which happens to be tweakable to explain what we see. It’s a very high quality toy, but nevertheless we have no theory that predicts it, and it’s wrong in at least a few different ways that we’ve currently discovered and have no workable fixes for. Super-Symmetry has pretty much been ruled out by recent experimental results, Super-String theory isn’t even testable. No-one has successfully managed to unify general relativity with Quantum Field Theory, and what explanations exist of Dark Energy and Dark Matter are barely tangible and untestable.

We know so much, but yet we know so little. Something’s going to give, despite the multitude of books written by prominent physicists proclaiming to being on the verge of understanding it all. Don’t belief them, they’re deluded!

Watch this space; the cracks are beginning to appear.
