Back Pocket Big Picture

(This article originally appeared at conservationtoday.org)

Over Christmas, according to the Carbon Neutral Company’s online calculator, my wife and I were responsible for the release of 4.2 tonnes of CO2 into the atmosphere – our share of a 19000km round trip flight from London to Los Angeles.   With two such flights a year, that makes our individual emission 4.2 tonnes, or nearly half the UK per person annual average of  9.51 tonnes.

To reel off excuses for this travel (my better half hails from the US, and we like to see the in-laws in the flesh occasionally) is to miss the point, which is that I, and many more like me, at least now have some awareness and quantification of the impact we’re making; our consciousness has been raised.

We’re all part of the problem, each with our own circumstances,  and each needing a plan to address our impact.   My plan might involve paying the Carbon Neutral Company’s recommended carbon off-set fee of £35.70 in support of a Chinese hydro-electric project.  It won’t on this occasion, because while I support off-setting as one tool in the bag of control measures,  I’ve chosen instead to donate to projects benefiting animals already affected by the complex interplay of climate factors – which I’m about to come on to.

Starting the year with a  knowledge of your personal carbon footprint is only part of the story.  While sufficient perhaps for the average citizen to act upon and make a difference, policy makers, industry leaders, NGOs, conservationists, educators, and the plethora of other stakeholders and interest groups directly involved in climate change issues, need the bigger picture.

This is the bigger picture I’ll be working to in 2009, and it comes from the UK Government’s former Chief Scientific Advisor – Sir David King.   It’s been in my head, sparking ideas and resonating with a whole range of experience since I scribbled it on the back of a business card back in November.   I saw Sir David at an environmental media awards evening organised by PAWS, where he used the diagram to illustrate the important challenges of the 21st Century, and their inter-dependency.

Examples of specific  inter-dependencies are well represented in Conservation Today articles: from unpredictable climate induced pathogen interactions impacting biodiversity, to corporate actions influencing food production, to how health and education are changing the global population dynamic.   King’s representation is helpful in encapsulating the whole smash; its something you can carry around in your mental back pocket.   Away from specifics,  it also for me informs at least three more oblique, but no less important, themes that I’ll now expand upon:

  • The importance of  not generalising
  • The imperative for interdisciplinary and international cooperation
  • An opportunity for business and an alternative to rampant consumerism?

Don’t Generalise

I’ll illustrate how generalisations are dangerous with reference to two processes: desalination and GM crop growing.

Desalination is a process that has been criticised for its energy intensity and associated CO2 footprint.  King referred to the Australian province of Victoria’s response to seven years of drought conditions, whereby a third of its water will in future come from new desalination capacity.  Ultimately powered by Australia’s plentiful coal reserves, the plants will indirectly yield CO2, which will warm the planet, which will intensify the drought, which will demand more desalination plants.   It’s a simplified picture – but you get the point; in this case technology is a short term fix to a  grim spiral.

I’ve since though found a more positive example of ‘Green Desalination’ in the form of California’s Carlsbad Project.  Here, a 50 million gallon per day desalination plant is being built to supply up to 8% of San Diego County’s water needs, involving co-location of the plant with a new power station at the coast.   The encouraging  part is that when completed in 2011, it promises to be the first US plant to have a net zero carbon footprint.

So why can the Americans do it but not the Australians?    First off – don’t generalise – every situation is different; processes and power stations are not inherently evil.  San Diego County currently imports 90 percent of its water from a distance of more than 800km, from Sacramento Bay Delta and Colorado River, and the electricity needed to deliver and treat that water is close to what the new plant will use.   The mitigation of the remaining ‘CO2 gap’ will be achieved at the site through initiatives like green building design; on-site solar power generation; funding renewables; and acquisition of renewable energy credits.  Further carbon dioxide will be sequestrated by creation of coastal wetlands and reforestation (we know how important those are, see here) – and that will impact biodiversity.  See how our diagram is working here?

We also generalise when we impose the luxury of our western standards on to less wealthy societies.  Increased desertification and flooding in some Asian regions is combining with a healthier, more educated, and therefore at least temporarily increasing, population, to demand that rice farming become more intensive.  This means farming on land that may flood, requiring flood resistant rice strains – which are readily available as GM seeds.  In practice though, farmers wishing to export product beyond their own needs refrain from using GM rice because of the negative attitude it attracts in the west.  As a result, such farms may fail to meet even local food needs.  Given my personal stance on GM crops, that amounts to a case of  “one man’s lifestyle choice is another man’s starvation”.

The imperative for interdisciplinary and international cooperation

Inter-relating challenges demand an increased coordination of the political, infrastructure, research, and educational aspects associated with each.   Global warming is possibly the defining example of a need for innovatory thinking combined with an imperative for pan-disciplinary co-operation; not only across the sciences, but involving engineering, medicine, commercial, and policy elements.   The slow progress made at recent climate summits suggests the required international policy infrastructure just does not exist.  So where are the rays of hope?   The world has high hopes of Obama, and his promised global energy forum could be part of a more mature future; remember this:

“In addition I will create a Global Energy Forum—based on the G8+5, which includes all G-8 members plus Brazil, China, India, Mexico and South Africa—comprising the largest energy consuming nations from both the developed and developing world. This forum would focus exclusively on global energy and environmental issues. I will also create a Technology Transfer Program dedicated to exporting climate-friendly technologies, including green buildings, clean coal and advanced automobiles, to developing countries to help them combat climate change”

And closer to home, encouraging exemplar organisations have emerged, such as the  University College London’s Environment Institute, who are developing a pan-disciplinary approach to global warming; and King’s own organisation, the Smith School of Enterprise and the Environment in Oxford, which aims to help governments, companies, and individuals meet future environmental challenges in the context of the bigger picture.

An opportunity for business and an alternative to rampant consumption

I could easily have overprinted the big picture interactions diagram with a giant $ sign, given that all our challenges are inescapably embedded in an economic and political web of capitalist growth imperative, feeding on consumption and wealth generation.     Question is – has that web, via the present financial crisis and to a background of increased environmental awareness, had a wake up call in any positive sense?

I’m going to stick my neck out and take an upbeat, even optimistic, tack on how business and the capitalist monster can become our greatest assest in tackling the century’s environmental challenges.   How come?   Because I believe there will be a significant shift of attitudes in (a) business awareness of the opportunities from environment related projects (like the Carlsbad desalination scheme), (b) increased government investment in such projects, both as a way of countering recession and addressing the underlying environmental need, (c) a less predictable re-think on the part of private individuals about the role of consumption – particularly excessive consumption in the west –  on their well-being.   I’m most optimistic about (a) and (b), precisely because the required technologies and management practices are at present so underdeveloped.   I’m less sure about the form of, or optimistic about how we might achieve, the revised international infrastructure needed to moderate individual nation’s interests.

Two Cultures

Are you a scientist, or more of an artistic person?   Or maybe you’re a bit of both?  Do you care?  And does it matter?

two cultures
Has the arts-science gap widened fifty years on? ©Tim Jones

It mattered to CP Snow in 1959, when he wrote the essay ‘The Two Cultures’.   Snow saw society split into two groups, or cultures: the artistic intellectuals and the natural scientists (natural because they study the natural world).   Each misunderstood the others language, ideas, and contribution.  The relationship was often one of unproductive hostility.

Fifty years on, towards the end of last month, I joined the London Consortium’s  ‘Art and Science Now’ programme, to see how Snow’s ideas are standing up in the eyes of leading figures from the world of arts, science, public policy, science communication and philosophy.

This post is part summary, part observation, and part photo gallery (thanks largely to  Sven Klinge, whom I met at the conference and who provided most of the pictures here).   Not all the speakers from the Dana event are reported here.   Don’t read any significance into that – its just a time issue.   Also, plenty of additional ideas came through in the final panel session and Q&A, which are likely to inspire future posts – but there’s more than enough to be going on with here.    The full event ran for three days, 22nd-24th January; I joined on 23rd and 24th.

NOTE: now includes a summary of Gillian Beer’s paper not included in the original post

First Day – 23rd January, Science Museum’s Dana Centre

The session kicked off with Steve Connor, Director of the London Consortium, introducing keynote speaker George Rousseau.

Reading a prepared text, Rousseau’s talk majored on the virtues and challenges of cultural collaboration framed as  inter-disciplinary working, including the concept of ‘bridging’.

Today, multi-disciplinary working is needs-driven by otherwise insoluble complex problems, yet we attack and treat with suspicion those who move between disciplines  – “we rush to shoot them down”.   Acknowledging that the best minds have always worked in multiple fields (Rousseau made the standard reference to Lunar Men here) doesn’t seem to help us.

Moving on to ideas of responsibility, can those on each side of the science / humanities divide understand each other sufficiently to be conscious of their respective responsibilities in the world?   Scientists might understand the arts better than artists understand science, but so what if they can’t sort out their responsibilities?   Can we not work with a unified sense of knowledge to achieve that?

Rousseau’s vision is for a world in which we all work across boundaries and know what we have to do (this is what academics call a crude summary).   Rousseau went on to discuss at length what that vision might mean within academia, such as the emergence of multi-disciplinary selection committees filling leading academic appointments with multi-skilled candidates.

Rousseau’s Q&A was short and disappointing.   A question on unified knowledge – asking how the different ways in which artists and scientists define the word knowledge might prevent sensible commune, was not engaged with.  I took the question to mean knowledge derived from ‘feeling’ – acceptable and embraced by the artist, as opposed to the scientists’ equivalent based on the ‘rational’.  But  Rousseau simply declared the word knowledge to be a lexical term and that he didn’t really know what knowledge was.  Considering the forum, I found that answer surprising and unfulfilling.


The Science Museum’s Robert Bud opened the afternoon session with his keynote speech.  Opening his talk with a photo of Dawkins’s atheist bus, Bud quickly took us back a hundred years, to the split between the  ‘two sides of the road’  in South Kensington – close enough to what we call the V&A and the Science Museum today.  The ‘arts side’ was painted as a backward looking centre for the maintenance of elitist taste; the science side more practical and forward looking, representing progressive materialism and a rejection of the spiritual.  The tension between these, Bud argued, formed the roots of Snow’s cultural divide.

Bud set his mission to the clarification of Snow’s real meaning.   In developing the story, he pointed to the iconic importance of Francis Crick’s DNA double helix, not only as the basis for life and replacement for the soul, but as the basis for Crick’s, and later Snow’s, fundamental beliefs.

Referencing an essay by Jacob Bronowski, Bud linked Snow to Crick.   With a letter from Snow to Bronowski as evidence, he showed that the content of Bronowski’s essay,  ‘the abacus and the rose – a dialogue concerning the two world systems‘, was aligned with the real intent behind Snow’s  essay.  Bronowski couched his text as a dialogue between Potts, a Cricks-type scientific stereotype, and Harping, a Kingsley Amis-type reader in English.  In the fictional debate, the artistic protagonist sees no beauty in life unless there is some subjectivity or element of human judgment associated with it.  Potts on the other hand, the scientist, has no need of that.  In other aspects too, the  Harping character generally meets our modern stereotype of an anti-technology, anti-progress, luddite.  This is starting to remind me of the themes in Dawkins’s ‘Unweaving the rainbow‘.

Sure enough, having implicated Crick with Bronowski’s Potts character, and aligned Bronowski’s views with the intent of Snow’s essay, Bud now linked Crick to Richard Dawkins.  Not only through their shared activity on genetic themes, but also through Dawkins’s atheism, expressed so recently on the sides of another British cultural icon – the London Bus.

Through this elegant, methodical, approach with use of evidence, Bud had boxed down Snow’s intended meaning to the sort of black and white intellectual stand-off that is unfashionable in some quarters.   Alan Sokal would later show a similar level of attention to the content and bounding of his argument.

Bud concluded, for the avoidance of any doubt, with this reference to the two cultures debate:  [it has] “not been primarily about the conflict between academic disciplines, between whether history or physics is more important, it’s been about materialism against the reality of non-material entities; about god and life.  Thank you

Second Day – 23rd January, Tate Modern Art Gallery

This was the first time I’d seen Marcus du Sautoy in the flesh.

With an appearance and demeanor  somewhere between a children’s TV presenter and a younger Jasper Carrott, wearing a tee-shirt emblazoned with the phrase  ‘i are scientists‘,  I can see how he’ll fit well into Dawkins’s old job, but definitely not his shoes.

Full of energy and wit, there is also something of the diplomat about du Sautoy.  The recurring theme of  ‘bridging’ came up, with maths as the unlikely bridge between science and the arts.  Du Sautoy explained the mathematical structure of music; he is involved in a range of projects that link the two.  He was sympathetic and supportive of the ‘artist in residence’ type of cross-rift exchange that one audience member was involved with.

Sad as it might seem, I’ve often pondered on behalf of Anthony Grayling, as to the wisdom of a book-branding philosophy that entails the title ending with the words “…of things”: ‘The Mystery of Things’, ‘The Reason of Things’, ‘The Meaning of Things’, ‘The Heart of Things’, ‘The Form of Things’ , for one tract of his extensive range of popular philosophy books.  Maybe it’s just me, but agonising over a purchasing decision in a bookstore, I can never remember which of these ‘things’ editions I already own, and invariably end up leaving the store empty handed.

Yet Grayling remains the philosopher I feel I could most comfortably engage with in chat over a beer.  His ability, without patronising, to transpose  complex ideas into the common tongue, combined with an unforced sense of humour, is appealing.

Grayling approached Snow from historical and educational perspectives.  Again, as Bud had stressed earlier, Snow was late to the debate.  In the early decades of the 20th century, Wittgenstein , whose texts Grayling reminded us would be familiar from our previous night’s bath time  reading, had defended the ‘feeling’ world of morality and religion from the reductive encroachments of the empirical scientists’ world view.

In 1880, at a time when the so-called Civic Universities, like my alma-mater Birmingham, were for the first time concentrating on scientific and practical subjects, Thomas Huxley addressed the issues perceived around the arts and sciences, spelling out the importance of a scientific education for all in understanding the world.  In retort, Huxley’s friend Matthew Arnold, while agreeing with much of his colleague’s argument for science, strongly defended a complementary role for the humanities as a vehicle for human reflectivity – amongst other virtues.

Yet class  was to override any happy balance that the Huxley-Arnold discourse might have anticipated.  The wealthy and influential social elite, trained in the classics from school through to Oxbridge, were empowered and equipped to exercise a disproportionate influence over society, compared that is to the growing, parallel yet separate, class of technically proficient industrialists.

Key developments in the twentieth century, Grayling argued, were a change in status for science in recognition of its  indispensability to modern infrastructure and the exercise of war, and the increase in complexity and requirement for specialism in scientific pursuits.

Specialism led to streaming in the schools system, separating the population at an early age into classicists and scientists.  It was this galvanisation through specialisation of an already divisive educational system that, Grayling argued, had prompted Snow’s commentary.  The powerful elite saw the importance of science, but without understanding.  It prompted the pithy rationale of keeping the “expert on tap, not on top”.   Efforts by the ‘new’ universities to introduce reciprocal training for arts and science students enjoyed  abject failure.

In summing up the position today, Grayling considered that in important respects, and specifically with regard to the scientific literacy of the general public and elected officials, Snow’s gap is very much wider fifty years on.  Further, this condition is damagingly influential on how scientific issues are being read.  Grayling pointed to how the public debate on evolution could only persist through ignorance of biology, causing a mistaken belief that there is any substance at all in the contrary argument.  The tradition of thinking in the humanities is, Grayling believes, more towards the need for neat answers and closure to issues and debates, representing the antithesis of the scientific acceptability of open ended questions.

Grayling closed with an appeal for scientific literacy, achieved in part through a change in attitude towards, and engagement as adults with, life-long learning.

The relevance of Charles Darwin to a debate on Snow might not be obvious; yet Gillian Beer made it so.

Before developing her main theme around extinction and Darwin, Beer informed us that Snow’s main reason for wanting to see science and technology working effectively in the world was so it could be used to combat global poverty.   Maybe that is a less well known, more human, driver in the debate around Snow’s motivations?

As it turns out, as illustration, Darwin’s attitude to extinction, and the various interplays of scientific, social, and personal experience that influenced that attitude, have much to inform our thinking.    When human beings are involved, thoughts and actions are rarely down to science alone.

For Darwin, said Beer, extinction was an ordinary necessity in the process of natural selection.  Without extinction there would be no new animals, no improvement.  And anyhow, the whole process dovetailed nicely with the Victorian cultural values of progress and hierarchy.

There was some sadness attached to species loss, yet the world remained full and in balance.   Why react?  Extinction is a gradual process; Darwin scoffed at the idea of cataclysm.   And there was every reason to believe the animal kingdom could continue to look after itself well into the distant future.

The very far  future was different though.  A cooling sun and dying earth played on Darwin’s mind.  The religious had their afterlife, but for Darwin the finality of an extinction of man was an intolerable prospect.

How different things are today.

Extinctions are more simultaneous and widespread; we contemplate E.O.Wilson’s ominous forecast of 50% species loss over 50 years.  And we feel guilt.  We can place five historical mass extinctions, and further cataclysm is a real prospect on a warming earth.

More positively, stuffed animals in glass cases have made way for movie films of living, moving, animals.    And, while like Darwin, we  might not see a personal eternity, our understanding of genes at least gives us some intellectual compensation that something  continues.

In her close, Beer came back to the theme of the interaction of science and culture over time, [concluding that while]:

different elements of Darwin’s theory point in different directions, and have been pressed into service by opposed ideologies; that does not undermine his experimental evidence or his theoretical reach, but it does I think demonstrate how the cultures of scientific enquiry, social assumption, and bodily experience all interact, over time, to change ideas.  Thankyou.

 

This was my second serving of Ben Goldacre in a week; having heard  him speak at a Centre For Inquiry event reported here.

Ben Goldacre

Today, less spontaneous and the better for it, Goldacre’s rant was unambiguously focused on the evils of the ‘humanities graduate editors’ of  mainstream news media.He really hates these guys, whom for Goldacre most closely resemble the Snowian (Snowic?, Snowoid?) stereotype of artist as scientific philistine –  ignorant, and dangerously active with it.

Goldacre’s thesis is that we have moved beyond a condition of mere disconnect in which arts graduates are dismissive of science, to one in which the same group feel entitled to make comment in areas and on subjects they know nothing about.   He resents the lack of in-depth science reporting in the mainstream media and, as a mantra now, champions the non-specialist  but educated reader – the people who “did bio-chemistry at Leicester, and now work in senior management at Marks & Spencers“.   He went on to illustrate his talk with slides covering a whole range of mercilessly crass and inaccurate reports extracted from his beloved tabloids and equally unsafe broadsheets.  For more, see Ben’s book Bad Science for an enjoyable read.

Goldacre gets his important points across with a sense of fun.   That said, today’s comic highlight was at his own expense when, during the final panel session, a deferential compliment back-fired.  Having answered a string of audience questions specifically addressed to him, Ben now paused to announce that as a mere ‘D-list’ public intellectual he should defer to the  ‘B-list’ public intellectuals – Grayling and Sokal – seated either side of him.Ben’s categorisation was arguably correct for a small population that counts Dawkins in its number, but that didn’t stop Ben changing colour in response to Grayling’s playful objection to his grade.

Jonathan Miller doesn’t like to be called a polymath.

Jonathan Miller

But what do you call a writer, performer, neurologist, and internationally distinguished director of theatre and opera?  Perhaps Steven Connor’s introduction of Miller as an intellectual amphibian was more acceptable; it got a smile.

Sitting across from his interviewer, Associate Director of the London Consortium Colin McCabe, Miller played upon his  intimidating status to the full, a status that has earnt him the right, and the expectation from others, to speak plainly.  He did so with a vengeance.

The idea of  ‘Two Cultures’ would be first a mystery, and second anathema, in the household of Miller’s formative years.   Engaged equally and variously as artists and scientists, the family were  simply doing what intelligent people did; they flitted effortlessly between interests.

Jonathan Miller (Photo Sven Klinge)

Schooling had played a part, but only in the form of an unruly master who ignored the formal curriculum, a reference that put me in mind of Richard Dawkins’s  reminiscing  about his happy days at Oundle School.   But how far would those examples get, elitist at best by current fashion, as educational models today?

With his neurologist cap on, Miller shared his fascination with the mind’s learning and skills capabilities.  For example, taking three days off from a failed activity can result in a skill magically appearing, subconscious processing  having kicked in unbeknown.

Miller’s latest interest is to form shapes and assemblies out of metal, just structures that interest him and which, again, he resists to label as art.   Art and science are very different things to Miller.  Most art is “to do with people doodling“, while science is “quite clearly directed enquiry prompted by a context which determines what is going to count as an interesting problem“.   He sees the “rightness” of what constitutes a satisfactory artistic endeavour is totally different to the “rightness”  of what can be concluded from science.

Miller took a similar line to Bud, in so far as he saw the important differences between art and science as quite fundamental.  As for the two helping each other out, Miller has  “deep suspicion of this notion of being artist in residence‘, a reference to an earlier audience point, and what he saw as an unnecessary  formalisation given that art and science are ‘in residence’ within each of us all the time.  He pointed to a nine year period between 1905 and 1914, when interesting developments ranging from relativity to cubism, to the de-construction of music, appeared as the products of a natural cross-fertilisation of interests.  The first cubist artists, responsible for the development of military camouflage, were not “artists in residence“, but “artists in uniform“, their input naturally falling into place.

Miller’s point, that the propensity for the arts and natural sciences to unconsciously intermingle is a product of the time we are living in, may well be valid.  Yet do we live in such a golden age today?  Maybe we need to make some clunky ‘artist in residence’ type gestures to kick the right-thinking along.  Miller conceded that the very complexity of science today made polymathism [my word!] a challenge; there are too few hours in the day.  Indeed, to expand on a recurring theme, it is problematic enough today for scientists in the same subject area to understand each others’ work.  In my experience, it is the same complexity and associated promise of narrowness that drives potential candidates away from a training or career in science.

In a forgivable ploy to avoid final-session empty seat syndrome, Alan Sokal was held back till the 4.00pm slot.

Alan Sokal and Patrick Wright

Sokal is something of an icon for followers of the arts-science debate.  In 1996, he wrote a spoof academic paper parodying the pseudo-intellectual content and style then being used by an academic group known as the cultural relativists – signatories to a particularly strong  flavour of post-modernism.  Their thesis as it applies to science is that science is made up – constructed –  by people to meet their political wants.  Any cultural relativist could write a ten thousand word essay on how over-simplistic that definition is; but that’s partly the point.  There is a socio-cultural angle to the most astringent definitions of science, but in the 80s and 90s it all got out of hand.  Meanwhile, Sokal’s meaningless paper was accepted and published by the journal ‘Social Text’.  His own revelation that the paper was meaningless did much to expose the low standards of evidence and understanding in the prevailing discourse of the cultural relativists.  It also precipitated what became known as ‘the science wars’.

Speaking on his birthday, Sokal immediately set out a field he could play on.  That meant  focusing on the relationship of science and scientific inquiry with society as a whole, rather than the Snow question per-se, and defining exactly which definition of science he would be talking about.

Sokal’s was an  appeal for a scientific world view in which we are all scientists, some better than others perhaps, but all working to the same rules.    The corner stones of this vision would be clear thinking and a respect for evidence.

Clear thinking meant also the clear writing that Sokal, and earlier Grayling, had demanded.  But what is science?   It suits some academic commentators not to bolt down definitions in this way, they see it as restrictive and narrowing of debate, but Sokal is firmly out of that camp.  It’s worth pondering Sokal’s four definitions of science:

  1. It denotes an intellectual endeavour aimed at a rational understanding of the natural and social world
  2. It denotes a corpus of currently accepted substantive knowledge
  3. It denotes the community of scientists with its mores and social and economic structure
  4. It denotes applied science and technology

Again, there are those who would argue the first two cannot be discussed outside of the second two, and would attach especial dependency of 1,2,and 4 on 3 – the social aspect.  Not so Sokal.

As if nothing had changed in the thirteen years since his ‘exposure’ publication, he launched a scathing attack on those who would deny that scientific knowledge constitutes objective knowledge of a reality external to ourselves.   In these moments, in that lecture hall, it felt like Snow’s rift had evaporated – ‘science’ had won.  There was no robust response from the floor as Sokal ridiculed one sociologist after another by relaying quotes from his book Beyond The Hoax.   For example:

the validity of theoretical propositions in the sciences is in no way affected by factual evidence – Kenneth Gergen

the natural world has a small or non-existent role in the construction of scientific knowledge – Harry Collins

for the relativists such as ourselves, there is no sense attached to the idea that some standards or beliefs are really rational as distinct from merely locally accepted as such – Barry Barnes & David Bloor.

For Sokal, this type of writing, and the thought behind it, aims to confuse truth with claims of truth.  Of course, any post-modernist worth his salt would head that one off at the pass with a denial of there being any absolute truth.   Sokal conceded that the more extreme forms of post-modernist thinking were now in retreat, in part due to his own efforts, but mostly due to the example provided by George Bush of where “science bashing” can worryingly lead.

A diversion into pseudoscience complemented Goldacre’s talk and led into the real point Sokal wanted to address  – the universal applicability of the scientific method across all areas of human activity.  Why do we use one set of standards for evidence in physics, chemistry and biology, and then relax the standard for religion, medicine or politics?  Sokal interestingly framed his argument for a unified approach as the “inverse of scientific imperialism“, whereby science should be seen as just one instance of the application of a rational world view in which empirical claims are supported by empirical evidence (the antithesis of dogma).

So at the end of the conference we had returned to a dichotomy of  rational and dogmatic world views  that Bud, the day before, had used to characterise and clarify as Snow’s true intent, and which Grayling had reinforced as the real issue.  And in conclusion to his talk, Sokal stated his belief that the transition from the dogmatic to an evidence-based world view is very far from being complete.

Natural Shrinkage

Back to the (more) serious stuff soon.  But to finish the apple story, how scary is this?

Scary
Scary

Hot on the heels of the Amazing Shrinking Head, I’ve dug this out of the archives.  Taken last year at Hampton Court Palace,  it’s an apple that has naturally dried out after someone stuck it on a spiked  fence.  With skin this time, there seems to be a natural predilection to eye-holes, and maybe a trace of nose?   (BenGoldacreDisclaimer – warning, one example does not constitute a scientifically, statistically significant, sample. Great Metro copy though).

But non significant
But not significant

The Amazing Shrunken Head

Here’s something you can be getting on with when you should be working etc.

Get that shrinking feeling
Getting a shrinking feeling?

It’s actually a little experiment the missus has been running right under my nose. And a fine demonstration it is too, of the scientific principle of  ‘DEHYDRATION’.

I’m sure you’ve already figured it out.  Peel an ordinary apple, carve a face on it, put it in the fridge.  Two weeks later – Mr Evil Applehead.

Enjoy!

Second Earth

This is pretty cool.  A getting together of Google Earth and Second Life to make ‘Second Earth’, located on (above?) the SciLands virtual continent, which I stumbled across while checking out a SciLands event this weekend.

Essentially it’s  a way to represent 3D data in Second Life, with the vertical scale exaggerated.  Explanatory video here plus a couple of my own InWorld pics.

Second Earth - A mash-up of GoogleEarth and Second Life

UK on Second Earth - Looking a bit flat?

Presumably it’s therefore possible to map the entire Google Earth contour data set into Second Life or a similar virtual world.  And, it follows that,  when our avatars are sufficiently programmed up with our personalities and such like, we can just set the thing running and jump into a hole in the ground with some sleeping tablets.  Matrix here we come – yeh!

I’m getting cynical.  Must be February.

Attenborough On Darwin

Reminder –  David Attenborough on Darwin, Sunday BBC1 9pm.   Here is Nature’s trailer.

According to the Radio Times, Attenborough gets hate mail from creationists over his views.

DA says:

“They always mean beautiful things like hummingbirds. I always reply by saying that I think of a little child in east Africa with a worm burrowing through his eyeball. The worm cannot live in any other way, except by burrowing through eyeballs. I find that hard to reconcile with the notion of a divine and benevolent creator.”

Nice guy (David A, not the other one).


Appearances Can Be Deceptive

I keep running into this demonstration of how strange our brains can be, so thought I’d have a go myself.

Have a look at the inverted face below.  Upside down, but still pretty cute eh?

Cute
Cute

Now look at the next picture where she’s turned the right way round – yuk!

But it’s exactly the same picture just inverted.  Our brains somehow pick out the individual elements of the face and reconstruct them as we normally expect to see them – I guess?   Personally, I can’t see a glum person in the top picture without turning my head to a degree – I’ve just discovered – not so good for my neck.

Not so cute.  Well, not so happy anyhow.
Not so cute. Well, not so happy anyhow.

This simple example was made by cutting, rotating, and pasting the mouth of the girl in the painting.

I saw something like this a couple of years back at the Exploratorium Science Centre in San Francisco.    The most recent demonstration I’ve seen was at the Weird Science event here in London earlier this month, where Richard Wiseman had us all in hysterics with a doctored picture of Margaret Thatcher.  That was doubly strange, as: (a) he’d turned the eyes round as well (which is the correct thing to do, but my painting struggles because of the hair) and, (b) rotated the image slowly, which revealed there is a certain point where the brain clicks over to seeing the ‘new’ image – the gestalt switch moment.

The Exploratorium exhibition also included so-called hybrid images of faces that change expression depending on how near or far you stand from them.  The effect still works very well on a computer screen, but you need to stand a long way back.

Not entirely sure how the brain processes compare for the two types of phenomena, but I find the ‘switch’ is more gradual with the hybrid images.   In deference to copyright I’ll not share the snaps I took, but you can find something very similar at the ‘Hybrid Images’ website owned by Dr.Aude Olivia, Dept. of Brain and Cognitive Sciences at MIT.
