Global Warming Canaries, Anyone? A short intro to why most scientists are worried about climate change…

18 08 2012

The current state of arctic sea ice (see graph below) sends a chill down my spine.

So what it says is that the ice is melting furiously, and looks like it’s not yet slowing down even though the days have started to draw in.

However, any scientist will tell you that no single data point can be used as evidence of global warming, there are simply too many fluctuations for anything to be concluded over anything but the longest timescales. We cannot simply look at the mean temperature for a hot year and say, there you go, global warming!

Now, the issue is, there are well-known cycles over pretty much all timescales – this pretty much undermines all serious attempts at prediction.

So, what to do? Well all is not lost; there are still some clever little leading indicators we can look at to give us that sobering wake up call.

#1:  CO2

Firstly, we know CO2 concentration is up, no doubt or argument, this can be seen in the famous Hawaii data above, complete with the seasonal ‘breathing’ by global plant-life. The argument is about whether the greenhouse models that say this will result in warming will turn out right. I honestly don’t know, but I wouldn’t even have to wonder if the CO2 levels weren’t going up, would I?

#2: A Record Breaking Rate of Record Breaking

Secondly, rather looking at averages or ‘new records’, we can look at the frequency of records. So rather than saying, “we just had the hottest summer ever in some parts of the US, there’s the proof” we can look at how often records are set all over the world – hottest, coldest, wettest, dryest and so on. This approach creates a filter; if it shows there are more records being broken on the hot side than the cold side, could this be an indicator? I hope not, because there are.

Again, it could be part of a long-term cycle that could bottom out any time now. But on the other hand, if it was going the other way, I wouldn’t have to hope, would I?

#3: Sea Ice

Now the sea ice. The sea ice is another proxy for temperature. The reason it’s interesting to climatologists is because it is a natural way to ‘sum-up’ the total warmth for the year and longer; if ice is reducing over several years, it means that there has been a net surplus of warmth.

CryoSat – The European Space Agency’s Sea Ice Monitoring satellite launched in 2010 – (Image credit ESA)

Today we are seeing a new record set for minimal northern sea ice. And not only is there less area of ice, but it is thinner than previously realized and some models now suggest we could be ice-free in late summer in my lifetime.

Now if that does not strike you cold, then I didn’t make myself clear. This is not some political posturing, not some ‘big-business’ spin, nor greeny fear mongering. It’s a cold clean fact you can interpret for yourself, and it could not be clearer.

So is it time to panic?

Well it can still be argued the melting is part of a cycle, it could of course reverse and hey, no biggy. After all, what does it matter how much ice there is?

Well, yet again, I hate to rely on the ‘hope’ that it’s a cycle. Because if it continues, the next effect will be felt much closer to home…

Sea Level

Sea level is the ultimate proxy for warming. Indeed, sea level change can be so serious, maybe it is the problem rather than the symptom. If the ice on Greenland and Antarctica melt, the rise in sea level would displace hundreds of millions of people and change the landscape so dramatically it’s a fair bet wars and famine will follow. Now that is serious.

So have we seen sea level rise? Well, yes. Here’s the plot:

Now, it looks pretty conclusive but hold the boat. Some say’s it’s proof of warming but not everyone agrees. It’s true it could again be a cycle. Also, the sea level rise is fairly gradual; what people are really arguing about is whether we should expect it to speed up. If temperature goes up a few degrees it could go up 5 or 10 times faster. The speed is the issue. Humanity can cope if the level goes up slowly enough, sure, countries like Tuvalu will be in big trouble either way, but countries like Bangladesh and cities like New York and London will only be in real trouble if the rate increases.

Actual Canaries

Canaries taken into mines in order to detect poisonous gases; the idea being they would suffer the gas faster than the people and if the canary dropped, it was time to vacate. Do we have systems that are hypersensitive to climate change?

Yes! There are many delicately balanced ecosystems that can can pushed over a tipping point with the lightest of touch. Is there an increase in the rate of species loss, or an increase in desertification? Yes!

We can also look at how far north certain plants can survive, how high up mountains trees can live or how early the first buds of spring arrive.

Again, these indicators fail to give solace. Everywhere we look we see changes, bleached coral, absent butterflies, retreating glaciers.

The conservative approach is to ascribe these changes to the usual cut and thrust of life on earth; some take solace from the fact that humankind has survived because we are the supreme adapters and that the loss of species is exactly how the stronger ones are selected.

Yes, we are great at adapting, however, to kill any complacency that may create, consider the following: for humans just ‘surviving’ is not the goal, that’s easy, we also need to minimize suffering and death, a much tougher aim. We’ve also just recently reduced our adaptability significantly by creating ‘countries’. Countries may seem innocuous, but they come with borders – and mean we can no longer migrate with the climate. Trade across border also needs to be of roughly the same value in both directions.  While some countries will actually see productivity benefits from global warming, most will not, and without the freedom to move, famine will result. Trade imbalances mean inequality will become extreme. The poorest will suffer the most.

So for now changes are happening, and advances in agricultural technology are easily coping; however, because ecosystems are often a fine balance between strong opposing forces, changes may be fast should one of the ropes snap.

Conclusion

Looking at the long history of the earth we have seen much hotter and much colder scenes. We have seen much higher and much lower sea levels. We are being wishful to assume we will stay as we have for the last 10,000 years. It may last, or it may change. Natural cycles could ruin us. And mankind is probably fraying the ropes by messing with CO2 levels.

Can we predict if we are about to fall off of our stable plateau? No, probably not. But is it possible? Heck yeah.

No cheating 😉

guess, dammit

Can you tell what it is? Its something you see often and comes in lots of nice colours 😉

Stuff I Wish I Had Read When I Was Younger

6 11 2010

Over the years I have supervised and mentored several PhD students, and recently our firm started to award scholarships to undergrads, and I was asked to support one such scholar. These scholars are from the best and brightest and so I got to thinking…

Graduates today have it tough, competition is tough, people work longer and harder than ever and stress is hitting us earlier and earlier in life – or so it seems. I would argue that, to some real extent, things have always been getting worse, and therefore by induction, we can prove that they have haven’t really changed at all.

No, the graduates of today have unparalleled opportunity to learn, to travel and to experience. The brightest graduates have the world at their feet and will be its commanders when we are are all retired and done for.

So what could I do to support this scholar? In the end it was easy – I asked myself – what do I know now that I wish I had known sooner? Most of this is in attitudes and is deep in my psychology, and is the result of direct experience – but it turns out that a healthy chunk of my scientific learning experience can be re-lived – by reading some of the books I think steered my course.

So I made a point to summarize some of the best science related books I have read (and some of the most useful internet resources I have found), and dumped the list complete with hyper-links in an email to the scholar. I hope she goes on to be president!

Now having gone to the effort, it would be a crime to keep this email secret, so here it is, (almost) verbatim!

================

As promised, here is a list of useful resources I wish I had known about when I was an undergrad. I am glad I got round to this, it should be useful for several other students I work with, and has also led to me revisiting a few things! I think I may brush it up and pop in on my blog if you don’t mind…obviously I won’t mention you!
Anyway, back to the business. To me, science is not all about chemistry, molecules, atoms, valence electrons and so on. To me, is is the process of trying to understand the world, and this set of materials I have hand picked, should you get through even a part of it, will not only educate but inspire.

This may not be the very best list, and I am sure there are many great books I have not read, but I have stuck with ones that I have, so you will have to rely on other people for further recommendations.

Jarrod’s reading list: science/psychology/economics & so on

  • I’ll start with something really easy, relevant and engaging – an excellent (if quirky) summary of material science: The New Science of Strong Materials – Prof Gordon  has written another on Structures that is also worth reading.
  • Ok, this next one is not a book, but a paper; I like it because it shows that many stuffy professors are wrong when they prescribe boring scientific prose for papers. This paper uses the criminal “us” and “we” and discusses subjects as if with a friend. Shocking form, especially for a junior scientist. This paper by an unknown, changed the world.
  • Guns, Germs and Steel” – this is large-scale scientific thinking at its best- the book looks at how we can explain why the world is the way it is (especially the inequality) by looking at how technology spreads through societies.
  • Mistakes were made…but not by me” – this is required reading if you want to work with other people, so its basically for everyone then…
  • Then to take it to the next level – “How the mind works…” – Stephen Pinker‘s other books are also good if you like this one.
  • “Flatland”, (full text here) was written in 1884, and is essential reading because it defines the cliche “thinking outside of the box”.
  • To make your upcoming economics courses more interesting, first read this easy-to-read popular book: “The Undercover Economist“.
  • Also, Freakonomics– it’s shameless self promotion by egotistical authors, but hell they are smart, so put up with it.
  • The Tipping Point –  Malcolm Gladwell is a current thinker I really like; he’s not satisfied to focus on one thing for very long – his other books are on totally different stuff, but are equally thought provoking.
  • The selfish gene” – Obviously I would firstly recommend “On the Origin of Species”, (full text here) but if you are short of time (which you should be as an undergrad), you can learn most of the basics, and also get updated (well up to the 1970’s at any rate) by reading Dawkins’ classic.
  • I couldn’t ignore statistics, so I will include two – one classic, “How to Lie with Statistics”  and a more modern one “Reckoning with Risk“, they are quite different, but either will get the important points across.

Alas, books are perhaps becoming obsolete, so I better include some other media:-

  • The first one is so good I can’t believe its free – try watch at least one a week, but the odd binge is essential too. http://www.ted.com/
  • Next, an excellent physics recap (or primer) – but  you need lots of time (or a long commute!) to get through this lot – look on the left menu for Podacts/Webcasts on this webpage: http://muller.lbl.gov/teaching/physics10/pffp.html – I cannot begin to praise the worthwhileness of this enough. It used to be called “Physics for future presidents” because it teaches you enough to understand the risks of nuclear energy, and the likelihood that we will all run our cars on water – and let you know when you are being duped or dazzled by big words.
  • When I was somewhat younger there was a TV show called Cosmos, hosted by Carl Sagan, you may know of it. You could watch in now here, though obviously it is dated, so perhaps you shouldn’t; the reason I mention it, is because it was key in creating a generation of scientists, people who were inspired by Carl to be inspired by the universe. The previous generation had the space race and the moon landings to inspire them, but since then science has been on a downhill, with 3-mile island, global warming, etc, etc, and we have had no more Carl Sagans to cheer for us; Cosmos was a rare bit of resistance in the decline of the importance of science in society. You may also know that there have been battles in society (well in the circles on intelligentsia at any rate) about science – on the one had the ‘two cultures debate‘ and more recently, the ‘anti-science’ movement (suggested in books like “The Republican War on Science“. I do not wish to indoctrinate you, but rather make you aware that being a scientist used to be cooler and used to be more respected and something is indeed rotten in the state of Denmark.
  • Getting back on track, here is an excellent guide to critical thinking (something else sadly lacking in the world) – don’t read it, listen to the podcast versions (also on itunes):
    “A Magical Journey through the Land of Logical Fallacies” – Part 1 and Part 2
    I think this should be taught in school. Brian Dunning’s other Skeptoid podcasts put these lessons into practice showing how a scientific approach can debunk an awful lot of the nonsense that is out there (alternative medicine, water dowsers, fortune tellers, ghost hunters, etc etc).
  • If you do happen to have any time left, which I doubt, there are several other podcasts on critical thinking – that use a scientific approach to look at the world and current affairs: –

=============

Postscipt – Dear readers, please feel free to append your own recommendations to my letter in the comments section below. If there is one thing I know well, and that’s how little I know. I feel I only started to read ‘the good stuff’ far too late in life, and so those with more years than me (or better mentors), please do share. But bear in mind, this is principally a science oriented list, and is meant to be accessible to undergraduates – I left out books like Principia Mathematica (Newton) because it is really rather unreadable – and the Princeton Science Library (though awesome) is probably a bit too intense. Also, in the 30 minutes since I sent the email, I have already thought of several others I sort of, well, forgot:

That’s it for now…





Confessions of Scientific Atheist

31 05 2010

The Evolutionary theory of Natural Selection makes extraordinary claims. It explains the ability of creatures to convert sunlight to useful energy, to spin silk, to metabolise sulfurous rock – and much more besides.

Such amazing feats in nature require an amazing explanation. The existence of a God is very helpful in this regard; after all, humans have designed diesel cars and digital computers, so why couldn’t an entity with God’s power and talent create all the nature we see?

The trouble many people have with Natural Selection, is that while it can clearly explain some biology, using it to explain away practically all biology (and psychology, language, culture, etc.)  is an extrapolation – and a big one at that.

Why do scientists allow such an extrapolation? Surely this is arrogance?

================

Thinking about this, I have an proposition…

If you come from the premise that there is nothing outside of nature (see my recent post), then it comes easily. If the God option is written off a priori, we have no other logical option than to expect that the gaps in our knowledge of evolution will be filled in eventually. This allows us to sleep at night with the extraordinary.

If you start from the premise that there is a God, then this will strike you are arrogant.

================

The constant supply of greater details, filling in the gaps, gives encouragement to those who feel the theory is right (see God of the Gaps). It’s a bit like looking for Nessy – we can’t do a Star-Trek style ‘scan for lifeforms’ to be sure she does not exist, but the more we search the less likely she is to exist.

Of course, while evolution explaining away the wondrous variety in life does not prove there is no God, it sure makes God less necessary, and less necessarily capable.





What exactly is ‘science’?

14 05 2010

I used to think science was the practice of the scientific method; i.e. you propose a hypothesis, you develop a test of the hypothesis, execute it and prove the hypothesis.

That worked for me until the end of high school.

At university, I was a true nerd. I read all my textbooks cover to cover (mainly because as I was too shy for girls and too poor for booze). During this time, the definition above started to fail. So much of the science was maths, statistics, observation, pattern recognition, logic and quite a bit of rote learning. Not all of it fitted into my definition of science. I became a fan of a new definition: science is the study of the nature of reality .

But then I did post-grad, and I realised that not much in science is ‘proven’ (I guess this is the point of post grad study). Evolution, for example, is not proven. That the sun revolves around the earth is not ‘proven’. I discovered that the only things that could be proven were ‘ideas’ about ‘other ideas’. Bear with me on this one.

Let us say we define the number system – this is an ‘idea’ or conceptual construction. Within this construction we can ‘prove’ that one and one is two. Because we ‘made’ the system, with rules, then we can make factual and true statements about it. We can’t do this about the real world – we cannot say anything with absolute certainly because we rely on flaky inputs like our own highly fallible perception.

It’s like that old chestnut: how can you be sure you are not living in a giant simulation? Of course you can argue that it is pretty unlikely and I would agree, and right there we have a clue to a better definition of science.

It turns out that much of modern science deals in ‘likelihood’ and ‘probability’ rather than proof and certainty. For example, we can say that the theory of evolution is very likely to be more-or-less right, as there is a lot of corroborating evidence. Science cannot be run like a law court – where the prosecution only need to reach a threshold of reasonable doubt to ‘prove’ someone guilty.

Aside for nerds: Science says you can use logic to prove things absolutely, but logic only works with ideas, and there is a breakdown between ideas and reality, so one can never prove things in reality. So it is thoroughly wrong for a court to say that someone has been proven guilty. The courts use this language as a convenience, to “draw a line under” a case as they have not found a moral way to dole out punishments based on probabilities. Imagine a world in which a murder suspect gets a 5 year sentence because the was a 20% chance he was guilty! Sports referees often operate in this decisive way, perhaps because it saves a lot of arguing!

Anyway, good science cannot just give up and say once there is consensus something passes from theory to fact. This is sloppy. We have to keep our options open – forever.

Think for example of Newton’s Laws of Motion. They are called ‘Laws’ because the scientific community had so much faith in them they passed from theory (or a proposed model) to accepted fact. But they were then found wrong. Strange that we persist in calling them laws!

It took Einstein’s courage (and open mindedness) to try out theories that dispensed with a key plank of the laws – that time was utterly inflexible and completely constant and reliable.

So it is that the canon of scientific knowledge has become a complex web of evidence and theories that attempt to ‘best fit’ the evidence.

Alas, there are still many propositions that many so-called scientists would claim are fact or at least ‘above reproach’. Evolution is attacked (rather pathetically), but the defenders would do well to take care before they call it ‘fact’. It is not fact, it is a superbly good explanation for the evidence, which has yet to fail a test of its predictions. So it is very very likely to be right, but it cannot be said to be fact.

This is not just a point of pedantry (though I am a bit of a pedant) – it is critical to keep this in mind as it is the key to improving our model.

Two great examples of models people forget are still in flux…

1) The big bang theory

2) Quantum theory

I will not go into global warming here though it is tempting. That is one where it doesn’t even matter if it is fact, because game theory tells you that either way, we better stop making CO2 urgently.

Back to the big bang.

I heard on the Skeptic’s Guide podcast today about an NSF questionnaire that quizzed people about whether they believed the universe was started with a massive explosion, and they tried to paint the picture that if you didn’t believe that, then you were ignorant of science. This annoyed me, because the big bang theory is now too often spoken of as if it were fact. Yes, the theory contributes viable explanations for red-shifted pulsars, background radiation, etc, etc, but people are quick to forget that it is an extrapolation relying on a fairly tall pile of suppositions.

I am not saying it is wrong, all I am saying is that it would be crazy to stop exploring other possibilities at this point.

You get a feeling for the sort of doubts you should have from the following thought experiment:

Imagine you are a photon born in the big bang. You have no mass, so you cannot help but travel at ‘light speed’. But being an obedient photon, you obey the contractions in the Lorentz equations to the letter, and time thus cannot pass for you. However, you are minding your own business one day when suddenly you zoom down toward planet earth and head straight into a big radiotelescope. Scientists analyse you and declare that you are background radiation dating from the big bang and that you have been travelling for over 13 billion years (they know this because they can backtrack the expansion of the universe). Only trouble is, that for you, no time has passed, so for you, the universe is still new. Who is right? What about a particle that was travelling at 0.999 x the speed of light since the big bang? For it, the universe is some other intermediate age. So how old is the universe, really?

This reminds us of the fundamental proposition of relatively – time is like a gooey compressible stretchable mess, and so is space, so the distance across the universe may be 13.5 billion light years, or it might be a micron (how it felt to the photon). It all depends on your perspective. It is much like the statement that the sun does not revolve around the earth and that it is the other way around. No! The sun does revolve a round the earth. You can see it clearly does. From our perspective at least.

Now, quantum theory.

Where do I start? String theory? Entanglement? Please.

The study of forces, particles, EM radiation and the like is the most exciting part of science. But being so complex, so mysterious, so weird and counter intuitive, it is super vulnerable to abuse.

Most people have no idea how to judge the merits of quantum theories. Physicists are so deep in there, they have little time (or desire or capability) to explain themselves. They also love the mystique.

I do not want to ingratiate myself with physicists, so I will add that the vast majority have complete integrity. They do want to understand and then share. However, I have been working in the field for long enough to know that there are weaknesses, holes and downright contradictions in the modern theory that are often underplayed. In fact these weaknesses are what make the field so attractive to people like me, but is also a dirty little secret.

The fact is that the three forces (weak nuclear, strong nuclear and magnetic) have not been explained anything like as well as gravity has (by relativity). And don’t get me started on quantum gravity.

———————-

Anyway, thinking about all these issues, I concluded that science was (definition #3) the grand (platonic) model we are building of reality, ever evolving to best fit our observations.

My man, Plato

That works well for me. However, I recently came across a totally different definition for science:

# 4) “Science is a tool to help make the subjective objective.”

OK I paraphrased it to make it more snappy. It was really a discussion about how science was developed to overcome the fallibility of the human mind. Examples of weaknesses it needs to overcome are:

  1. The way our perception is filtered by preconceptions
  2. How we see pattern where there is none
  3. How we select evidence to match our opinion (confirmation bias)
  4. How we  read too much into anecdotal evidence
  5. etc etc.

I could go on. So ‘science’ is the collection of tricks we use to overcome our weaknesses.

I like this definition. We are all going about, and in our heads we are building our model of the world… and its time for an audit!





Evolution in the toilet bowl

2 04 2010

No, this blog is not about how evolution theory is going down the toilet, crushed in the cold grip of reason by The Discovery Institute.

This blog is about how toilet bowls can be used to show speciation forces at work [speciation – the birth of new species].

You see, I have just recently moved to the US, and have noticed the toilets here exhibit characteristics different to their UK and European cousins. Most specifically, US toilets are filled far higher with water and the water surface is greatly increased in diameter. Furthermore, the flush-handles in the US are more often on the left, rather than on the right as they are in the UK.

How can it be in such a small and networked world, such a speciation could occur and indeed survive?

———————————————–

A short stroll on the ‘net does not reveal much about how Americans came to prefer deep water, so I will have a guess. Presumably some big brand (like American Standard) was strongly dominant and the flagship model offered deeper water –  perhaps to prevent skid-marks, or maybe to ensure ‘complete submersion’. As this brand was so strong it was copied, and became the standard. Time passed, and now the average american might turn their nose up at the European low-level option (or indeed the interesting Asian options).

Question: When a European sees an American toilet, are they amazed at its superiority?

No. People don’t like change – and the deep American version is probably not actually any better. For example, the chance of urine splashing on the seat (or on one’s rear for those sitting) is increased, and so therefore, if anything, I would say the ‘deep dish’ is inferior.

So what does this say about evolution? It shows how a contraption, in different environments, will evolve to become different. But more interesting (to me at least) is that Americans and Europeans are not really significantly different and thus the pressures at play were really rather random. It is not as it American toilets have evolved to be stronger because Americans are larger (that would be no surprise) –  this ‘depth’ evolution is different – and very real, but the result of an almost random mutation (of the water depth) that is perhaps not any fitter, just different, and it has survived, despite its weaknesses, due to its isolation across the pond.

What I am saying is that in replicating systems, things will drift apart (there is a natural divergence) on a fast time scale, and the survival of a trait is on a longer time scale. Perhaps in 200 years time we will see no more deep toilets, but right now we have a new species.

Thus I propose you may actually get speciation from drift alone without fitness actually being tested.

———————————————-

So will a device that gently catches one’s emissions and silently whisks them away, instantly, with no splashing, odour, mess or need to flush will supplant the lot? No, because it will probably be expensive, and this cost pressure will always ensure room in the ‘ecosystem’ for multiple solutions – the “two planks over a ditch’ option will always be around because it is so cheap and simple.

———————————————–

Anyway,  next time you go, think about what the toilet might teach us about the subtler aspects of evolution by selection. It’s valuable thinking time after all!  🙂

———————————————–

Epilogue: an aside on valves…

There are obviously several competing technologies for the flush valve, and none has proven clearly superior; so the fact that the US does not (in my short experience) have a very high penetration of the siphon valve (‘claimed’ by Thomas Crapper), does not surprise me. It is indeed much more leak-proof than the popular ‘flapper’ valve, but more complex and thus prone to breakdown. However, the newly popular half-flush siphon valve, which can be easily retrofitted looks to be a clear leap in its evolution. Competition is hot though, and heading to the US, we will wait with bated breath to see which technology wins out 😉

Some references:

Environmental pressures are a new force in the future evolution of the toilet. First we had the dual flush, now we have the “No Mix” toilet that keeps 1’s and 2’s apart for tailored treatment! http://www.sciencedaily.com/releases/2010/03/100310134258.htm





The Apple Mac: It’s a religion…

6 02 2010

It has been explained by writers better than I how our minds are wired in a way that makes them vulnerable to religion.

Whether it is our desire to feel secure or have simple and complete explanations for natural phenomena or simply because we enjoy the social scene at church, there is no doubting the power of the effect. Even in modern times, entire lives, indeed entire civilizations are devoted to the superstitious concept of supernatural Gods.

Although L. Ron Hubbard may have started a religion while knowing it was all a sham, most religions did not need such deliberate action. Our innate need to have faith in things has allowed religious concepts to emerge and evolve freely in our communities as far back as records go.

So why do I bring that up?

It occurred to me today while pondering why people are so defensive about Apple Mac computers – I realised that their behaviour had much in common with religious ‘zeal’.

Then it occurred to me how much the success of Apple relies on perception and conception. If it was just about getting the fastest computer, you would not buy a Mac. If it was about buying something that has wide compatibility, you would not buy a Mac. If it was about cost, you certainly would not buy a Mac.

Some might argue that Macs are more intuitive and ‘easy to use’. These are people whose idea of computing is buying a shiny box, plugging it in and doing exactly what they are expected to do. They are people who just accept it when they are told they need to buy a new printer. Or worse, they blame the printer – what a crappy printer, not compatible! These are people who do not need to set up a complex network, or run a database server.

Anyone who has a Powerbook G4 that cost several grand and is not actually compatible with the latest OSX release, yet needs that OSX release in order to actually work, and still hugs and caresses the machine as it it were a newborn baby while defending its honour and wanting to spend another several grand on a newer shinier one, is, in my opinion, dabbling in a cult.

OK, before you write me off as some sort of anti-mac fanatic, I will admit they are beautiful.

Moving swiftly on, I think it is worth analysing Apple’s success.

How does a company that controls the details of their products so completely compete with a product (the PC) that is made by hundreds of companies all constantly competing, innovating, coming and going, rising and falling? The modular design of the PC allows almost anyone to buy all the bits and assemble the machine themselves; with so many companies making monitors and keyboards and hard drives, some will make bad (fatal) decisions and die, some will make good decisions and thrive and if there are enough upstarts to keep up the supply, the consumer will only ever see the winners, even if their victory was a flook, it was a victory none the less.

You could say that PC is the computer you get from natural selection (survival of the fittest), the Mac is the the computer you get when you try to control the evolution (unnatural selection).

Now a company that tries to make everything itself can capture the value chain, sure, but as it is only one company, it cannot make even one fatal decision, and thus needs to be a little more cautious. This means it is doomed to always lag slightly on the performance vs value curve – so what does it do?

Easy, get the consumer to accept poor value. Make up for performance by buying in high quality technologies (lcd screens, hard disks, etc), and make the customer pay the premium. Then focus on marketing.

Marketing is the art of making people want something. It is unnecessary for products people need.

So what happened at Apple?

Apple, perhaps by good luck, became perceived as a David vs the Goliaths of IBM and Microsoft. For some reason (was it deliberate?) Apple computers gained traction in music recording and graphic design, and gained a sort of bohemian chic that is rather impressive considering that it is essentially “Big Business” and, like most companies, designed to make money.

Clever partnerships, and particularly the inspired partnership with Adobe (think Acrobat PDF’s, think PhotoShop) strengthened their position with journalists, publishers and illustrators establishing the Mac as the creative profession’s computer of choice.

This turned out to be a good thing, as the naughties have been the most art friendly decade yet, as popular culture has come to resent things like ‘work’ and ‘industry’, and a certain sections of society have come to view activities like sport as trivial and meaningless when compared to the value and depth in culture, poetry, good food, yoga, spiritualism and so on.

In other words, the artists have moved up in the world.

Some of the more switched on folk will realise that brands like Gucci/Armani/Christian Dior or Ferrari/Porche/Aston Martin  or Rolex/Michel Herbelin/Patek Philippe are based entirely on massaging the egos of their customers, and in the last case, they probably don’t even keep better time than a black plastic Casio.

But not many of the arty crowd have realised that Apple is using their independent nature against them. The Mac user seems to be infected with the idea that in using a Mac they are somehow being beneficent to the world, will somehow be more creative, they they are part of some loving brotherhood that has exclusive access to the truth and the light.

This is because, by accident or design, the Apple brand has been developed to find that part of our mind that wants to believe and wants to belong, and is easily dazzled; the brand is acting like a religion.

Apple’s alliance with artists continues with U2 and the Black Eyes Peas, both highly credible symbols of free-thinking modernism. But I want you to ask yourself: what is free thinking about this computer company? I’m not sure, but I suspect the only free-thinking thing about Apple is its association with icons of the free-thinking world. It is just an electronics company for Pete’s sake. Like Sony, like Samsung, like Nokia.

If you believe there is any more to it than that, then you are welcome to pay for it.

PS: Besides the defunct G4 in the drawer, there is also an iPod classic in my home. I like it. I like to hold it. Mmm.
