Ascanio Sobrero, Nitroglycerin, and a Big Noise in a Small Village

3 Comments

Today is the birthday of the inventor of nitroglycerin: Ascanio Sobrero.

Ascanio Sobrero
Ascanio Sobrero

Born on 12th October, 1812, the Italian chemist made the discovery while a student at Turin University, by treating glycerin with hot sulphuric and nitric acids.

The industrial and military successes of  nitroglycerin are well known, particularly where it’s been used in stabilised forms as in Alfred Nobel’s patent dynamite.  Less well known is the catalogue of horrific accidents that punctuate the early learning curve of this powerful explosive.

I stumbled upon the echo of one such tragedy while holidaying in Wales this summer.  A lucky stumble too, as the plaque that records the Cwm-y-Glo explosion of 1869 is easy to miss: only locals and wandering hikers need apply.

It’s unlikely David Roberts, Evan Jones, Robert Morris, Griffith Jones, and eleven year old John Jones had heard of Ascanio Sobrero.  Likewise the villagers who collected those victims’ unidentifiable remains after Sobrero’s invention sent them flying in pieces onto the hillside and surrounding villages.

The two horse-drawn wagons at the centre of the disaster, each laden with a ton of nitroglycerin, or  ‘powder oil’, were on the eight mile journey from Caernarvon, on the Welsh coast, to the Glyn Rhonwy slate quarry near Llanberis.

The cargo was destined to blast slate, but when it exploded prematurely just outside the small village where its minders had stopped for refreshment, it likely created the loudest man-made noise known up to that time.    And despite Glyn Rhonwy being one of the first quarries to trial nitroglycerin1starting in 1866, they clearly hadn’t mastered the murderous sensitivity of its handling.  The full report of the accident as it appeared in The Times newspaper is reproduced in reference 4 below – with all the gory details.

The political and economic  impact of the Cwm-y-Glo explosion travelled well beyond Wales.   One direct consequence was the introduction of the Nitro-glycerine Act (1869)(reproduced as ref(3) below): “An Act to prohibit for a limited period the importation, and to restrict and regulate the carriage of Nitro-glycerine“(2), which put severe controls on the explosive’s importation, transportation and use, and encouraged the market for safer alternatives like gun cotton (cellulose nitrate) and Nobel’s dynamite.  Supposedly a temporary measure, during which time “there would be an opportunity given to scientific persons to inquire whether the compound known as nitro-glycerine was an innocent explosive or not.“(2), the restrictions lasted long enough to prompt heated debates around ideas of trade restriction and monopoly.

But the local impact was human, as the following ballad from the time shows.  I’ve had a crack at translating the first few verses from the Welsh (with my father’s help!) – just to get the gist.  The author,  Abel Jones, seems to be catching the brutal reality of the event in true Victorian style.  You can find the whole piece here.  (And, if you’re able and up for it, feel free to translate the whole thing and put it in the comments!)

Rough english translation:

“A ballad about a terrible explosion that happened in 1869 at Cwm y glo.

Dear quarrymen and all rockworkers throughout Arfon and Meirionydd.  Hear about this alarming and terrible accident that has made many hearts sad. There has been accident after accident in the quarries, with falling loose rocks from morning to noon.  They tear the flesh and break the bones and people collect bodies in blankets and sheets.  What heart does not melt at the sight of a mother unable to recognise her son or husband, the tears pouring from the children shouting: ‘Dad, where are you?’. And things are far worse with nitro-glycerine.  We’ve had terrible disasters at Abergele, now we have one at Cwm y glo ”

And the original Welsh:

CAN AM Y
DDAMWAIN ARSWYDUS
Hoff chwarelwyr a’r holl greigwyr
Drwy Arfon a Meirionydd sydd
Clywch alarnad am hyll ddamwain
Filain wnaeth ryw fronau’n brudd

The Times, July 2, 1869

The Nitro-Glycerine Accident. CARNARVON, Thursday.

The terrible accident we reported yesterday by telegraph has led to lamentable results. It seems that four tons of nitro-glycerine formed part of a cargo from Hamburg (Messrs. Noble and Co.), to Carnarvon, consigned to Messrs. De Winton and Co., for Messrs. Webb and Cragg, Glynrhonwy Slate Quarry, Llanberis, sole agents in Carnarvonshire for nitro-glycerine, used instead of ordinary powder for blasting rocks. The ship was moored in the river Menai, and a portion of the explosive oil having been placed in the Llanddwyn magazine, the rest was brought in lighters and placed on the quay in Carnarvon. About 1 o’clock noon, the hour appointed to cart that portion to the quarries, some of the vehicles did not arrive, and, after a delay of some hours, the two carters who have been killed under- took to remove a portion of the nitro-glycerine. These carts left about 4 on Wednesday afternoon, for Glyn-rhonwy Quarry, one of the numerous quarries lately opened on the south aspect of the Vale of LIanberis, and at the foot of Snowdon. A portion of the nitro-glycerine was to be removed today to the Dinorwic Quarry. The other three carts were left for the night in a closed coachhouse, near Bodenalgate, within a mile of Carnarvon, it being too late to re- move the oil to the Penrhyn slate quarries. These are now in the custody of the police. The two carts which caused the accident, were, it appears, in company, and were noticed within a few yards of each other just be- fore the explosion. The exact spot where the accident occurred is where the diversion of a new road lately made by the Llanberis and Carnarvon Railway joins the old road, about 400 yards beyond the centre of Cwm-y-glo village, five miles and a half from Carnarvon and 300 yards from Pont Rhyddalit, the bridge that spans the narrow water uniting the upper and lower lakes of Llanberis. At the time the accident occurred the quarrymen were returning along the road from their occupations to Cwm.y-glo village, when suddenly, without any warning, the quarrymen in front of the carts and those behind heard one long continuous explosion of terrific noise. This spot being surrounded by high mountains on three sides, the echo of the first explosion reverberated several times, as some of those that witnessed the accident informed us, and one mountain seemed to throw the noise with quick succession from one side of. the valley to the other over the lakes. The two lakes, especially the lower, were at once greatly agitated. Clouds of dust, stones, portions of the carts, and the walls around for two roods were either thrown to a great height or cast longitudinally either into the morass on one side or the rocks adjacent. A third of the circumference of a wheel was thrown 50 yards high and fell near a cottager’s garden on the sides of a rocky hill 300 yards off. Portions of flesh and bones (either human or those of the horses) were collected indiscriminately from a radius of 50 yards and placed in cloths. A foot, a chin covered with beard, and a man’s heart were found together about eight yards from the spot. The Cwm-y-glo  Railway Station (the nearest building to the scene of the accident), an inn lately finished, close by, and several (fortunately) unfinished houses a little further off, as well as a chapel, present a desolate sight. The roofs nearest the accident are perforated by falling stones, and window- frames have been blown in and destroyed. The massive doors of the goods department of the railway station are shattered, and windows all round within a radius of two miles present marks of the explosion. Scores of men were thrown down. Those known to be killed are -David Roberts, 35. a native of Denbigh, married, carter; Evan Jones, 22, Tyddyn Llywdyn, Carnarvon, unmarried (son of a widow, partially dependent on her son), carter; Robert Roberts, 26, quarryman (who had only returned from America a few weeks since); a quarryman who was supposed to be passing at the time,.and another whose name we could not ascertain resident at Cwm-y-glo.  About 12 persons have been seriously hurt and as many slightly injured. A leg and in two other instances arms have already been amputated, and two boys-Owen John Roberts and Griffith Pritchard have suffered internal injuries by being thrown down. The greatest distress exists, and even this morning the police were engaged searching the neighbourhood of the accident picking up very small portions of flesh and bone. Such was the terrible power of the oil that the spot where each cart is supposed to have been at the time of the accident is marked by two deep perfectly circular holes, of the same size, each measuring 7ft. 6in. in diameter and 7ft. deep, and a horse-length apart. The stones appear to have been subjected to a terrible rotatory motion, and the holes are in the shape of an inverted cone. Our correspondent, who was at the time of the accident sitting at a friend’s table in Bangor, ten miles off, experienced a shock and heard the rattling of windows at five minutes before 6, about the time fixed by those who witnessed the, accident. The shock was experienced more or less for many miles around.

Imagine a future world where technology lets us control our own destiny, enhance our physical and mental performance, extend our lives – perhaps indefinately. How will we come to see ourselves as human beings?  What will it mean to  be human? And how can we manage it all for the common good.

This is the world of Humanity 2.0, and the subject of a new book from Warwick University Professor of Sociology Steve Fuller.

I have to say up front this is the first of Fuller’s books I’ve read through cover to cover, and frankly it was quite a challenge.  Whether it’s the sociologist’s writing style or the somewhat discordant mix of practical and theological content, extracting what Fuller is really trying to say, his thesis if you like, was an uphill job.  To his credit, Fuller has made a series of six short videos summarising his content, and which I’ve added to the end of this post.  They came too late for me, but you’re advised to watch them before reading the book.

That said, I want here to give an overview of the content and critique a few areas particularly where I have issues.

Fuller wants to create egalitarian policy for the development and implementation of transhumanist technologies, and justify sociology’s seat at the multi-disciplinary table that will deliver it.  It’s the laudable focus of his Chapter 3.

But his broader agenda is to dethrone what he sees as a prevailing hegemony of Neo-Darwinism (essentially what Darwin knew plus our knowledge of molecular genetics) and get an alternative variant of intelligent design (I.D.) taught in school science classes; p180:

…the most controversial aspect of my position, namely, that the active promotion of a certain broadly Abrahamic theological perspective is necessary to motivate students to undertake lives in science and to support those who decide to do so.

He’s accordingly raised his game by developing a brand of I.D. better suited to the task as he sees it; p177:

As a true social constructivist, I see myself as one of the constructors of intelligent design theory.  I am not simply remarking from the sidelines about what others have done or are doing, as a historian or journalist might.  Rather I am making a front-line contribution to defining the theory’s identity.

although it’s not clear how much of this is driven from  heart-felt conviction.  Variously describing himself as a Secular Humanist, Humanist, and now Transhumanist, in this Guardian interview  from 2006 he appeared not to favour I.D., but felt it deserved a “fair run for its money”; apparently backing any horse, however lame, that will run against Neo-Darwinism.

Fuller’s appeal to I.D. in Humanity 2.0 is itself ambiguous: he uses the term variously in contexts related to a recognisable deity, p187:

I have been quite open about identifying the ‘intelligence’ of intelligent design with the mind of a version of the Abrahamic God into which the scientist aspires to enter by virtue of having been created in imago dei.

then more in relation to nature, as in his discussion around civic religion, p182:

But what remains specifically ‘religious’ about ‘civic religion’? Two aspects: (1) Science’s findings are framed in terms of the larger significance of things, nature’s ‘intelligent design’, if you will. (2) Science’s pursuit requires a particular species of faith – namely, perseverence in the face of adversity – given science’s rather contestable balance sheet in registering goods and harms….

The former quote is consistent with Fuller’s broader counter to Neo-Darwinism, my reading of which can be summed up as (i.e. my words):

Those committed to a Neo-Darwinist world view are aligned with a historical tradition that decrees we can never know a god who is different from us in kind.  Such people are uninterested in science or technology beyond that required for a continued existence with their fellow animals in a sustainably snug microcosm.  They likewise have no interest in the science and technology of a transhumanist agenda.

It’s never quite clear whether Fuller is projecting God’s image onto man, or man onto God – a model more in line with his version of secular humanism as described in the aforementioned Guardian interview: “human beings at the centre of reality, creating God in their image and likeness” and “taking control of evolution”.   With I.D. tied up with hardcore Creationism in the US, however inappropriately from Fuller’s perspective (he doesn’t support Creationism), some clarification would be helpful.

Coming to structure and content.  The first two chapters major on the idea of human ‘distinctiveness’, or that which makes us uniquely human, discussed in the frame of race and  religion aligned with various biological and theological perspectives from the past, present, and future.  Chapter two specifically defines world views broadly corresponding to ‘naturalistic’ Neo-Darwinism, and a divinely-inspired alternative.

Where naturalistics see themselves “embedded” at one with nature, animals like any others emerging from a process of evolution with natural selection, the divinely-inspired are special: fundamentally separate and above animals, they recognise God because he is an intelligently-designing technician as they are, intent on preserving the essence of their specialness – their humanity.  Traditionally they’d look to do that in soul form, but now have an eye to the alternatives future transhumanist technologies might offer.  All a bit sci-fi for now, but think of uploading thoughts, memories, consciousness to a microchip, robot, clone, hive-mind, or whatever.

Chapter three’s more grounded ‘Policy Blueprint’ centres around the so-called Converging Technologies Agenda (CTA) for the delivery, management, and regulation of technologies for human enhancement, or transhumanism; so: Nanotechnology, Information Technology, Biotechnology and Cognitive Sciences working together under Fuller’s favoured policy regime of ‘anticipatory governance’.

Although more a check-list than a roadmap – I’m still uncertain of the next steps, there’s interesting discussion here on topics like the substantive PR task of selling transhumanist ideas to a CT-sceptical public (think nanotech), use of IT-style early-end-user-involvement to progress it, and the role for media and science communication.

We can expect issues around personal risk and willingness to participate in enhancement technology trials.  Fuller points to the danger of CT perceived as hollow rebranding (again, echos of Nanotech’s relation to chemistry), and questions around standards and norms for developments and applications: e.g. would we take a nanotech or medical lead in a medical situation using that technology?   There are also emerging and diverse management philosophies to accommodate or rationalise; so the USA taking a more ROI-focused, proactionary, human performance emphasis, hands off approach; while Europe favours a precautionary, state-controlling, human welfare emphasis.

For Fuller, sociology’s egalitarian pedigree, manifest in the Welfare State, qualifies its latent contribution.  And with funding for CT industries biased to the private sector, it looks like the common man is going to need a champion.  No centrally driven, government funded, benevolent upgrade for the species this.  The portents are rather for increasing societal inequality and differentiation: a position Fuller contrasts with the public-focused ‘common good’ research environment of the Cold War.  Cynically, and outside any higher moral ambition, CTA could simply serve as a ‘techno-fix’ for over-population or other pressures on the Welfare State, forcing us to work harder and longer for our deferred pensions – no thanks, or getting us off the hook of our ecological responsibilities.

It’s all scary stuff. When we’re popping cogno-enhancers over the cornflakes, and little Jimmy’s off to college by the grace of his cerebral implant, and your investment-banker neighbours have signed up for the latest ‘life-doubler’ programme; one wonders what will qualify us to live, never mind defining our humanity.  That’s me fantasising,  but drug-based cogno-enhancement is here, and Fuller’s born “always already disabled” scenario could happen, hitting hardest the under-priviledged and those who don’t want, or can’t afford, the latest upgrades.

Chapters four and five are a return to theology and full-on Neo-Darwinist bashing, which is a shame given I suspect there is so much more to say in the vein of Chapter three.

Various off-shoots and mini-theses sprout off the core agenda, like discussion on the debt owed to religion by Science and both the Secularist and Enlightenment movements for their existence, albeit with a concession the influence has waned:

..even if it is true that all supernaturally motivated scientific insights are eventually absorbed into the naturalistic worldview, it does not follow either that the supernaturalism was unnecessary or that naturalism is the final word.

Newton appears as the quintessential religiously motivated scientist, which is fair enough provided we remember back then he had only religion to explain anything.  It’s interesting to ask what sort of science a modern-day Newton might pursue.  Would he be one of Fuller’s Neo-Darwinists for whom ‘God differs in kind’, causing him to eschew all impractical science like cosmology, particle physics and String Theory?

I do struggle with this idea that scientists can’t, won’t, or won’t want to do fancy science unless they turn all ‘intelligent design’.  It’s saying we have to be designed in order to aspire to knowledge or value truth.  Or that because Neo-Darwinists wouldn’t recognise God if they found him curled up in the 10th dimension, they wouldn’t bother with String Theory.

Yet scientists, many of whom are Neo-Darwinists, do that kind of science – big time!  So what is it – force of habit?   Well why not?  Maybe we enjoy all that Brian Cox ‘wonders’ stuff because of an evolutionary misfire: a historic brain artifact associated with some evolved inquisitive tendency for practical survival.  We do fancy science, we make a discovery, we revel in our dopamine spike, we do more fancy science.  Simples. That’s why scientists are such fun folk to have around.

Fuller might see that as a reductionist, even nihilistic, worldview.   He’s said that when Darwin killed God he also killed man, or the only part of man that matters – his humanity.  And this is why despite presenting his arguments in a frame of reasoned academic detachment, I’m coming round to thinking Fuller’s propositions are at end religious plain and simple – even if the religion is his own science-flavoured brand.  He ‘feels’ there is no humanity without god, so we must have god.

Conclusion

If you’re not used to reading sociology texts, which I’m not, Humanity 2.0 is hard going.

It should be clear by now that Humanity 2.0’s high-tech cover art conceals a heavy theological edge with pervasive references to intelligent design in the context of an anti-Neo-Darwinism agenda.  And that’s a shame because it distracts from the more diverse, and frankly more interesting, material also there in plenty for those with open minds.

There’s nothing wrong with theological arguments per se, but mixing rational policy debate with what many will see as off-the-wall, politically charged, I.D. rhetoric is a mistake that’s likely to destructively provoke the very individuals and organisations Fuller should be onboarding to secure sociology’s role in the transhumanist agenda.

Unweaving the Waterfall – Erasmus Darwin at Vauxhall Gardens

1 Comment
Vauxhall Gardens (artwork Tim Jones)

Grandson Charles and Grandfather Erasmus Darwin had at least one thing in common besides their illustrious name: they both took delight in figuring out how the world works – which isn’t to say they always followed the same interests.

Charles, we know, focused on the natural world – often in great, great, detail.   Erasmus, less fixated but still very much the naturalist, engaged also with just about every aspect of science, technology and the trials and tribulations of the human condition you can imagine.

Erasmus Darwin
Charles Darwin

As happy in the botanical garden as the coachmaker’s yard or canal digger’s trench – it was all the same to him, many are the fields where Erasmus Darwin’s substantive contributions, too often unsung, resonate to the present day.

And while Charles was doubtless adventurous in mind and deed – he did afterall make the voyage of the Beagle – Erasmus, in the broader sense I would argue, ‘got out more’.

No surprise then, one evening in 1756, to find a 24 years young Erasmus Darwin at the epicentre of London society and entertainment: the pleasure gardens at Vauxhall.  Less surprising still to find him back at his Nottingham lodgings pre-occupied with reverse-engineering the Gardens’ then prize crowd-pulling spectacle: the artificial waterfall, or Cascade – more of which later.

Vauxhall Gardens in 1751 (five yrs before Erasmus’s visit) Samuel Wale (Wikicommons)

The twelve acre Vauxhall Gardens operated from 1661 to 1859, and enjoyed a fantastically diverse clientele.  Anyone who was anyone – or aspired to be –  had to show their face: from Kings and Queens to honest tradesmen, to a dependable spattering of pick-pockets and prostitutes.

Entertainments at Vauxhall (Photo:Tim Jones. Exhibit at Museum of London)

All mixed shoulder to shoulder, intent on  enjoying music, dancing, or one of the many laid-on spectacles: illuminations, fireworks, circus acts, mechanical wonders, balloon rides, battle recreations and panoramas celebrating the fetes of great explorers.  Top of the list for many would be a romantic diversion with a favoured beau or belle under the tree-covered walkways.

Vauxhall Gardens by David Coke and Alan Borg

Incidentally, if you’re wondering what prompted this post – digging around in a pleasure garden – it’s down to my latest reading: a new History of Vauxhall Gardens, by David Coke and Alan Borg1: a beautifully presented, comprehensive, and accessible read.  Check out the book’s website here and write-ups in the Guardian here and here

I’ve suffered from amateur social historian syndrome since arriving in London eleven years ago – it’s hard to avoid when the place drips with the stuff; but the Vauxhall interest is closer to home – literally; my old flat on the Vauxhall Bridge Road overlooked the former Gardens’ site.  Now home to a plain-vanilla grassed park, the only reminder of former glories is the yearly bonfire night sputter of fireworks launched by good-natured, if boisterous, locals. (On which theme, check out this earlier post).

Echo of past glories. View from my flat in 2003: fireworks rising from the former site of Vauxhall Gardens (Photo: Tim Jones)

Reading the new history though, I was intrigued by how few famous scientists (natural philosophers in their day) or technical folk are associated with the Gardens, either as self-reporting visitors or through third-party narratives .

Maybe the great and the good of the scientific establishment eschewed egalitarian Vauxhall in favour of the more exclusive (and expensive) Ranelagh Gardens across the river in Chelsea?  At least there was a stone bust of Isaac Newton on permanent display at Vauxhall.

Anyhow, it’s entirely possible a trawl through the personal letters of individuals, where they’re catalogued, would turn up further references.

For my part, I checked out Erasmus’s letters –  and he didn’t disappoint.

Coming back to the artificial waterfall or cascade for a moment.  Installed in 1752, Coke & Borg say of it:

To add to its theatricality, the Cascade was concealed behind a curtain which was drawn back at a particular time in the evening, as night fell, to reveal a three-dimensional illuminated scene of a landscape with a precipitous waterfall; the illusion was created with sheets of tin fixed to moving belts, turned by a team of Tyer’s [the owner] lamplighters; when it was running, the noise and spectacle must have been terrific 1.

Then I found this letter from Erasmus, dated 9th Septemebr 1756, describing his interpretation of the operation of the spectacle to his friend Albert Reimarus, drawing and all:

Erasmus’s drawing of the artifiicial waterfall or cascade at Vauxhall Gardens (Picture credit: The Collected Letters of Erasmus Darwin, Cambridge University Press, 2007, Letter 56-6)

“The artificial Water-fall at Vaux Hall I apprehend is done by pieces of Tin, loosely fix’d on the Circumferences of two Wheels.  It was the Motion not being perform’d at Bottom in a parabolic Curve that first made me discover it’s not being natural.  The Velocity at Top is not so great to my rememberance as at the Bottom half of the fall, as I suspect the top Wheel is less than the lower one; a Shade is put where the Wheels join.  At Bottom are many less Wheels I conjecture.  Now the Velocity of the fall from a to b not being encreased was another thing that shock’d my Eye.  What you mean when you say “let the Water fall  over a Parabola etc”, I don’t understand.“

Photo:Tim Jones. Exhibit at Museum of London.

I’m taking expressions like “The Velocity at Top is not so great to my remembrance….” as evidence Erasmus actually visited the Gardens himself in the summer of 1756, possibly accompanied by Reimarus.

For Erasmus, the waterfall ‘game’ was given away by the shape of the flow – something other than parabolic, and not moving at the expected relative speeds.

In fairness to the designer (the concept likely derived from Francis Hayman’s theatrical stagecraft), that exposing the spectacle as anything other than natural required such analysis seems high praise indeed!  Incidentally, Coke & Borg maintain no visual representation of the cascade exists, so this might be as close as we get.

(As an aside, there’s also evidence Erasmus’s sister Susannah (Sukey) visited the Gardens.  In a letter of 12th June 1759 to his wife Mary (Polly), Erasmus accuses his sister of exagerating the number of people attending, 30,000, saying that number would not fit3 (although audiences of 12,000 are known to have gathered).  There’s also a much later association with Charles Darwin, that appears in the correspondence4; not that he visited the Gardens but, as a twelve year old boy, having watched one of Vauxhall’s favourite performers, a ventriloquist named Mr Alexandre, did imitations of animal calls – interesting eh?)

We should take care when talking about Erasmus in this period not to visualise him along the lines of the podgy, red-cheeked albeit aimiable 38 year old captured by Joseph Wright and hanging in the National Portrait Gallery.  In 1756, Erasmus was 24 years old, single (he married Mary/Polly Howard the following year), and largely unknown; he’d only two months earlier unpacked his bags in Nottingham to start his first medical practice.

So this is before he moved to Lichfield, and way before the invitation to become the King’s physician, his rivalry with Samuel Johnson (of dictionary fame and a regular at Vauxhall Gardens to the degree he appears in contemporary prints), or his adulation as England’s best loved poet.  Moreover, the brief spell Erasmus spent in Nottingham is sparsley covered in the literature, with no mention in the standard biographies of trips to London or the Gardens. There’s just the one letter as far as I can tell.

In conclusion, it’s nice to see Erasmus’s early credentials as both engineer and bon viveur reinforced in the one story (however much, as a fan, that assessment might be tainted by confirmation bias :-)).

In their longevity, Vauxhall Gardens represent a unique microcosm, a laboratory for the study of change in societal norms, fashion, culture, politics and contemporary opinion.  Coke’s and Borg’s analysis refreshes our insight on these, and placing Erasmus Darwin at the scene adds to our understanding of his early life.

Update 4/9/11

Twitter friends have suggested Samuel Pepys as an example of a ‘scientist’ known to have visited Vauxhall.  He for sure counts as one of the establishment great and the good, and was a president of the Royal Society to boot.  Coke and Borg do talk about Pepys, who wrote at some length about Vauxhall Gardens in his famous diaries.  I’m afraid I associate Pepys so strongly with the Gardens, and for all his other interests and achievements – not just in science, that I completely forgot to mention him – poor chap.  Still, he’s one guy, and it would be interesting to see if any of the other famous scientific names of the day including Newton, Wren, or, as Rebekah Higgitt (@beckyfh) suggested via twitter, Edmund Halley or Joseph Banks made mention of Vauxhall experiences in their letters.  I must say, if I had my bust up there in all its glory like Newton did, I’d be checking up on it every friday night.

On the technology website Ars Technica last week, Jonah Lehrer argued that taking a sneaky peep at the end of a novel to see how the plot works out needn’t necessarily spoil a good read.

For myself, I quite like surprises, in fiction at least, so for the foreseeable future I’ll be taking my revelations, denouements, and tricks-of-the-tale in the order the author intended.

Real life’s different though, and I do for the most part like to see what’s coming.  And, for sure, there are any number of would-be oracles, specialists, think-tanks, and other miscellaneous pundits ready to enlighten me.

But therein lies a problem.  When the brain gets too much information from too many sources it doesn’t cope so well.  And given that this is all important stuff we need to have an opinion on: over-population, global warming, peak oil, mass epidemics, starvation, save the panda – asteroid strikes; what’s needed is someone to critically scan, boil down, and filter the myriad forecasts and predictions into a digestible round-up.

Enter Jon Turney’s latest book, The Rough Guide to The Future

(The Rough Guide to The Future (Rough Guide Reference))

‘Rough’ is a curious term to describe a guide that in style, by my reckoning, is both scholarly and popular; but, as Turney says, it’s really more of a recognition that no study about everything can ever be complete.

All the same, Rough Guide to the Future is as comprehensive an analysis of forecast data and topical opinion that you’re likely to find, and one I heartily recommend.

I should also say that I read the Guide, in a fitting juxtaposition of futurity with the primal, on my smartphone whilst halfway up a mountain in a tent.  And while I’m sure there’s virtue in that, I’m missing the pencil scrawl and Post-its I’d ordinarily now be pawing over for a review. Kindle highlights and notes just don’t do it for me.

Here goes anyhow.

In terms of the certainty of its themes and predictions, the Guide follows a sort of three part soft-hard-soft progression. Kicking off with a more philosophical discussion around types of futurity and the methods of futurology, there follows a middle section on relatively near-reach developments on issues we really need to sort this century – so a focus on the 50-100 year time scale.  With more speculative and far-reaching ideas boxed off in the later chapters, it’s an effective mix that majors on practical concerns but with plenty of material to keep budding futurists, sci-fi enthusiasts, and philosophy types on board.

Chapters combine quotations, literature survey, case studies, a Prediction File, and a Further Exploration section (references to futurist texts, various government, NGO and think-tank reports, plus a good dose of science fiction).  The Guide is packed with helpful hyperlinks.

The Predictions Files capture the diverse views of fifty invited commentators asked for their highest hope, greatest fear, and best bet for the future.  Turney’s own replies give something of the flavour:

Highest Hope: “We navigate through the eye of the needle of the middle decades of the century well enough to allow the bottom billion a real chance of a humane life.”

Worst Fear: “The environmental calamity so many informed scientists predict gathers pace faster than our efforts to forestall it.”

Best Bet: “Crises, muddling through and continuing vast inequalities are the order of the day.  In spite of that, it remains, technologically and culturally, the most fascinating of times to be alive.”

Scanning the whole set is a roller-coaster ride between optimism and pessimism. From Anne Skare Nielsen’s High Hope along the lines of the world being what we make it:

“That the majority of the world’s inhabitants will come to the sensible conclusion that if we keep on asking others to change, nothing grand will ever happen.  That we – as Buddhists say – have to be the change we want to see in other people.  We should stop instructing and start constructing.  I hope that we can let go of our need to control, learn to “listen louder” and co-create better solutions that will bring out the best in people”

to the sombre hopelessness of Sohail Inayatullah’s Greatest Fear:

“Endless fear, endless poverty, endless loss of spirit, continued nationalism, crisis after crisis with the inability to see the links, deeper causes, or pattern of crises.”

I touched on ideas from the first part of the book, related to time perception and the nature of past and future in my last blog post, so won’t expand further here.

The ‘hard’ ground at the core of the Guide comprises discrete chapters on what Turney calls Global Basics: energy, climate, water, food, health, biodiversity, war, and disasters.  These are preceded and supported by generic discussions on science futures and population, and followed by material covering softer issues (but not as speculative as those in later chapters) around life, societal values, economic models and sustainability, and global cooperation – the logic being these topics overlay or integrate with the Global Basics.  In the chapter Life, Society and Values, I particularly liked the description of Futurelabs’ 3-Worlds exercise, that considers how the world might look were we to adopt or migrate to different sets of dominant social values.

I’m not about to trot through each and every Global Basic here, but it’s impossible to write, or write-up, a guide to the future without mentioning energy and climate change.

Unfortunately, the problems associated with climate change come in two flavours neither of which, as a species, we’ve met before on any scale or have a record of resolving: (a) their impact is global and therefore shared, and (b) they operate over multi-generational timescales.  The challenge is well summed up in former Shell chairman Ron Oxburgh’s Worst Fear:

“That each country acts in its own perceived short term interests in the belief that this will maintain or raise its economic competitiveness; that emissions will continue to rise, and wealthy nations will use their wealth and technology to achieve a degree of short-term adaptation to a rapidly deteriorating climate, allowing the developing world to take its chances.”

If  there’s one common message from the whole guide, but particularly the Global Basics discussion, for me it’s the need not to see our scientific, technical, societal, and political futures in isolation.  It’s easy to retreat to a technical focus, but some thought leaders are striving for the bigger picture – as challenging a task as that might be.  This quote from Tim Jackson of the UK’s Sustainable Development Commission stuck with me:

“the reason why nobody asks the difficult questions that we are asking here is because nobody really has any answers to them”

A somewhat depressing prospect given that the difficult questions are also the important ones.  For me, the apparent absence of any roadmap to transition from what we appear to be in – a treadmill of unsustainable, consumer-driven growth, is deeply worrying.  Few believe this is the century mankind will ramp up to some Utopian ideal, but it will be a poor show if we can’t make substantive corrections to the inequalities in health, wealth and opportunity that characterise today’s (in)humanity.

Incidentally, another message I gleaned from the Guide is that forecasts are, or should be, constantly revised – and some, like the impact of birth rate on future population, are sensitive to small changes.  Likewise the need to question received truths and revisit sources.

Moving to more speculative territory in the last third of the Guide, I should mention how through his many references Turney pays tribute to science fiction.  Since the 19th century, science fiction writers have painted imaginative alternative futures built around surreal technologies, alien life, and revolutionary social orders; and the fiction of the past has often become the fact of the future.

I’ve never been a science fiction nut, but remember as a teenager lapping up futurist works like Arthur C Clarke’s Profiles of the Future and Report on Planet 3, then in the 90’s Francis Kinsman’s Millenium 2000, and most recently Damien Broderick’s Year Million collection.  Now, thanks to the Guide, I’ve rediscovered the works of H.G.Wells and W.Olaf Stapledon – who both convince me how few ideas are truly new.

There’s discussion around life extension, cryogenic preservation, and transhumanism – including the increasingly ubiquitous concept of The Singularity, a condition some think will arise, even within the next 50 years, whereby technology and artificial intelligence will run exponentially away from us, designing and building ever superior versions of itself – even attaining its own form of consciousness.  My take from the Guide on this?  The jury is still well and truly out.

The good news is that through improved nutrition and medicine many more people will be living very much longer (but not necessarily at their leisure).  And through genetic upgrades, we’ll be enhancing our physical performance, visual range, and cognitive abilities.  A brave new world made real.

Then there’s the prospect for life on other worlds, the concept of deep time, and the ultimate fate of life, the universe, and everything;   which, cheerfully, boils down to the heat death of the universe in some tens of trillions of years: a concept clarified not as some giant toasting (although the Earth does get one of those along the way), but the end of heat, energy, and everything from the potato chip to the proton.

So sitting in my tent having completed the Guide, from the seemingly overwhelming challenges of Global Basics to the end of the universe, I ask myself the obvious question: “Does it really, cosmically speaking, matter if I don’t get up and go to work?….”.

At which point I remind myself I’ve two more weeks of holiday to go, and keep on smiling.

After all, there’s still time to put things right.  And the end of the future is a long way off.

Blast Through Your Past – with Google Street View

2 Comments

“in Sensation we believe external Things exist, in Memory we believe they were, in Imagination we neither do the one nor the other” (Erasmus Darwin quoting poet Richard Gifford back to himself in a letter of 1768.)

Here’s something to try if you haven’t already done it: make a Google Street View tour of all the old homes you’ve ever lived in.

Of course, if you’ve yet to leave the parental home it’s going to be a dull exercise, but if you’ve been around a while and lived in lots of different places, there’s the joy of reminiscing and spotting that the new owners have gotten around to replacing that leaky porch you ignored all those rainy winters.

Street View hasn't caught up with the Belgians - or vica versa

It took me half an hour to track down the twelve places I’ve lived in, bought, or rented over the years (some in the pic above); although the flat I lived in for four years in Brussels came out as, well, flat.  Belgium seems to have been overlooked by Google Street View)

Apart from the idle interest, dredging the past evokes ideas around the concept of time and how we store information and remember things; although if that’s just me, it’s because I’m presently transitioning between two books that touch on the topic: The Information by James Gleick and Jon Turney’s Winton Prize-longlisted The Rough Guide to the Future.

We capture so much nowadays – Gleick: “The information produced and consumed by humankind used to vanish  – that was the norm, the default.  The sight, the sounds, the songs, the spoken word just melted away.”

Then came the first marks on paper, drawings, writing; then photographs. Gleick again:

“Now expectations have inverted.  Everything may be recorded and preserved, at least potentially: every musical performance; every crime in a shop, elevator, or street; every volcano or tsunami on the remotest shore; every card played or piece moved in an online game; every rugby scrum and cricket match.”

Whether it’s Street View, Flickr, or Friends Reunited, there’s a bunch of stuff pushing in on us, persuading us to reconstruct our pasts in a way that was alien even five years ago.

What does it mean?  Is it good?

For sure, any ideas we might have had about ‘clean breaks’ and ‘moving on’ get a good muddying.  Old friends: material and personal, reappear unbidden – sometimes welcome, othertimes unsettling away from their original context.

In his chapter About Time, Turney says our memories impact our ability to think about the future; afterall, past experience is pretty much all we have to draw on.

The way we build memories, he says, may have adapted specifically to enable the efficient anticipation of new situations, and there is even evidence of a physical link in how we think about past and future events – neurological scans revealing common areas of brain activity.

Our memories “seem to work by storing individual pieces of past experience separately, as part of a complicated, interconnected web …. Our brains then assemble recollections of past episodes by adding together bits of information that seem to be related.”

As it happens, by Turney’s reckoning, I’m probably at the optimum age for projecting  possible futures.  Meaning, I’m old enough to have collected some experiences, but not so old I’ve forgotten them all.  (I love some of the terminology people use for age brackets, particularly the ‘old old’ – meaning over 80.  At 49, I’m holding out for ‘young middle-age’.)

I want to wind up the post by sharing some great life-changing revelations resulting from this technology-induced disturbance in my mental time-space continuum and reassessment of ‘self’. But as the most emotionally charged evocations seem to relate to the unfeasible number of lawnmowers I’ve owned over the years, I’ll skip on that and instead leave you with a bit of topical DNA:

The Moon Hoaxing Scandal of 1835

Leave a comment

Herschell pictured on a papier mache box lid at the Museum of the History of Science, Oxford (Photo: Tim Jones)

The fantastic weather in Oxford yesterday meant museum visits took a back seat to a good punting session on the Cherwell (a violation of physics in its own right with me at the helm).

Oxford (Photo:Tim Jones)
Oxford

But we did get a half hour in the Museum of the History of Science , where I snapped this papier mache box lid, a great early example of newspapers not letting facts get in the way of a good story.  For what they lacked in hacking scandals in 1835, they made up for in hoaxing, in stories like the one to which this exhibit relates: The Great Moon Hoax.

The picture is a satirical sketch of the astronomer Sir John Herschel, in a scene based on a series of reports by Richard Adams Locke for the New York Sun in 1835, supposedly describing observations made by Herschel at his South Africa observatory.

From the New York Sun 1835 (Wikicommons)

You can read up on the detail at the museum of hoaxes), but in this rendition, which is new to me, I particularly like the weird equipment combo Herschel’s minions are wielding around him: some sort of camera obscura / microscope mash-up by the looks of things.  Maybe those instruments were more familiar than telescopes?   Or, more likely, the  journo just let his imagination get the better of him.  Either way, I guess it’s still the little winged moon-men that steal the show.

The exhibit put me in mind of two lectures on a similar tack I enjoyed in the Royal Society’s History of Science series.   You might like to check them out:

‘Fleas, lice, and an elephant on the moon’  by Dr Felicity Henderson (Sept 24 2010)

‘The Telescope at 400: a Satirical Journey’ by Richard Dunn (April 24 2009)

A couple of months back, I sent away for a free set of genome fridge magnets from the Open University.  Problem is, our fridge is a built-in one hiding behind solid Brazilian Rosewood chipboard/oak veneers; and they aren’t magnetic.

One cool radiator....

Talk about blessing in disguise.  Now we have this fantastic genome-inspired  central heating radiator.  Good eh? (There’s me, then there’s Damien Hirst.)

So, 22 matching pairs of chromosomes, plus an X-Y pair (because I claim to be male; females have an X-X pair), for a total of 46.

Cool radiator.  Result.

Birmingham’s New Library is Virtually There

3 Comments

Notes:

22/7/11: I’ve added an update to this post at the end.

25/9/13: Daden’s slideshow on the finished project added

I’ve got a bit of a soft spot for Birmingham.   I visited the museums when I was a kid, and particularly liked the Museum of Science and Industry.  Then I spent six years studying engineering and researching at the University during the 1980s: many happy memories there too.  But I don’t think in all that time I visited the main public library; at the University we seemed to have everything we needed on campus.

Anyhow, I’m making up for it now with a visit to Birmingham’s NEW library – all from the comfort of my armchair, and at six o’clock in the morning no less.

While construction of the actual building is ongoing, this virtual world simulation in Second Life has been built to help the designers test out the design and make some fine tunings based on public reaction.

Regular readers might know I’m quite sympathetic to virtual worlds, although I’ve often felt I’m ahead of the curve in my enthusiasm.  This simulation by virtual world consultants and builders Daden Ltd reminded me of a similar pilot the London Strategic Health Authority built in association with Dave Taylor‘s team at Imperial College, to test out peoples reactions to getting around a building delivering centralised medical services.  I found out about the Library project from a post on Hypergrid Business Magazine; so hats off to them.

Anyhow, I think one of the points of these exercises is to judge first reactions and impressions, so this post is just my unedited walk-through, stopping now and again to take virtual photographs, with a few of my thoughts along the way.  For the avoidance of doubt, I’m the guy with the NASA 50 tee-shirt and angry ant buried in my shoulder – don’t ask.   I’ll remind you how to make your own visit at the end of the post.

Birmingham sure has changed since I lived here.  You appear in the simulation next to an explanatory board outside the library in a large piazza.  Real photographs on easels are scattered around the simulation showing how real-life construction of that particular bit of the library is progressing.

I thought I’d get cute and do what I’d do in real life, arriving at, say, the British Library in London: get my priorities right and suss out the coffee, toilets and restaurant.  The other important resource is a place to plug in my computer and recharge my phone.  And w-fi of course.  And a place to sit.  And on-line catalogues.  And books.

Anyhow, they were way ahead of me.  The first little bit of interaction that hits you is a survey of how you like to take coffee: with friends, with  a good book, place to meet up with folk etc.  There’s instant feedback on the poll in the form of coloured pillars proportional in size to the response.  I could have ticked several boxes, but plumped for coffee with a good book.

As it turned out, there are quite a lot of toilets.

On to a cafe / restaurant area.  This all has a great feel to it by the way, with a good sense of space and scale.  On the eating front though, I wasn’t clear quite what will be on offer; i.e. will there be various grades of bar, cafe, restaurant, fine-dining etc.  Maybe they don’t know yet.

More loos.

Looks like a theatre, although I didn’t manage to get into the auditorium itself.  I think I’ll pop back later in the day and see if any of these desks are manned by virtual people.  I did bump into one other visitor on this crack of dawn visit, but no project people.

This is cute: kiddies area with kiddy-size furniture and cuddly penguins and stuff lying around.  Middle-age man with ant on shoulder hanging around.  There was also some attractive Spanish Steps-style cushioned seating in this zone; think my camera jammed on that one.

 

Here’s a bunch of those wind-open walk-in book cabinets you find in libraries.

This is the Youth Zone again, with practice booths on the left.  Not sure what’s being practiced  – languages maybe?

Working up the building, here’s a suitably dark-tomed business area.

Interesting to see if this artwork makes it to real thing.  Again, this sort of thing in the simulation conveys the tone and attitude of the place.  More loos, notice.

Some empty spaces still to be developed: meeting rooms maybe?   Incidentally, I like the way this simulation lets you walk through the occasional unopened door, or even wall.  Interaction adds realism, but fiddly interaction for no purpose  – like aligning yourself with a revolving door to get through it – is just irritating.   They  got the balance here right I think.

This was quite something.  Towering walls covered in books.  Guess we’re in a library.

Near the top of the building is a roof garden.  Some nice views over the piazza.  Reminded me of the Royal Festival Hall on the South Bank – only better.

Top floors are staff only: explains why I couldn’t get up there.

The only weird techno-hiccup I found.  Sit down to play the piano and you fall into the floor.

Free of the Carbonite, taking in the cultural vibe.  Looks like some Friday evening entertainment, drink in hand, can be had.

Speaking of which.  The whole consumption thing in virtual worlds is a little weird by the way; but you can imagine what this area will be like with folk milling around after work.

And off I go.

In conclusion, it’s fair to say I got a pretty good overall impression of how the building is likely to feel and the facilities on offer.  If you want to know how the actual library activities will work: how to access databases and such like, that’s not what this is about.

I just whisked round quickly today, but I’ll go back later and leave some feedback.  The Hypergrid piece talks about various feedback mechanisms – virtual Post-Its and such like, although I can’t say they jumped out at me.  I’m also guessing the library may add more interactive tools, videos and such like explaining more detail on the facilities, as time goes on.

It will also be interesting to see if the simulation is kept alive after the library-proper is built; I’m thinking simultaneous broadcasts of events from the lecture theatre for example.  Very handy for us London-dwellers.

As promised: if you want to visit, you’ll need a Second Life account (free), and then teleport to the Library of Birmingham region.  You can find me in Second Life as Erasmus Magic.

Overall, looks like a great library in the making; and a friendly, intuitive job on the simulation by the library staff and Daden.

 

UPDATE 22/7/2011

Information point

That was one fast whistle stop tour.   So fast, as Soulla Stylianou from Daden kindly pointed out, that I completely missed the Library Guide I should have picked up on the way in: a sort of Heads-Up-Display that lets you take a self-guided tour and draw on extra info from the various giant turquoise i’s floating around.

So I’ve just made a return visit to virtual Birmingham – suitably equipped this time – also taking in the aptly named ‘Book Tour’, an annotated ride taken magic carpet fashion on a giant book.  And why not?

I now know amongst other things about the close integration on the project with Birmingham Reperatory Theatre (REP) and, for example, that the practice rooms are for musical instruments, not, as previously suspected, languages.

I also found that for more background to the project, the best starting point is this briefing area, where there’s also DIY training on offer for the Second Life novice.

Lastly, I checked out the interactive control and feedback tools; the simulation lets visitors:

– in ‘annotated spaces’, make comments in the form of smiley-ball graphics that other visitors can in turn comment on , voting an idea up (agree=green) or down (disagree=red).  Active votes range from an appeal to ensure desks are made user-friendly for disabled people, to someone who doesn’t like the yellow carpet.

– with a click change the furnishings / decor / mood of an area, i.e. gallery, music, seating :

 – vote on multiple choice answers to questions posed by the organisers.

Second time around, I’m still of the view simulations like this, while not perfect, bring an angle to communications – and in this case I guess a consultation – that can’t be achieved any other way.  I like the comment/voting system; it will be interesting to see how many green and red smileys appear over the coming months.

Ducks per Second: A Most Useful Unit of Velocity

2 Comments

Figure 1 - Sand Martin approaches from rear of convoy

Figure 2 - Sand Martin passes over second duck in convoy

When I lived in the Midlands of the UK, away from the bussle of London’s controlled airspace, one of my pleasures on an evening was to hire a light aircraft at my local airfield and tootle off for an hour or so practicing maneoveurs and generally enjoying the sunset – all very peaceful.

Except, one evening when I was out tootling above the Cotswolds; like a flash, an RAF Tornado jet whooshed from under me, matching my track but far exceeding my speed, and all uncomfortably close – a disappearing dot before I could blink.

In fact, he was probably a good 500 ft below me and certainly had on-board radar – so nothing actually dangerous going on. (There’s a popular myth  – that may be true – that on such occasions the military use light aircraft for practice interception.)

Anyhow, it made an impression on me, and today the memory returned unbidden with these two photographs snapped at the Rick Pond in Hampton Court Park.  They show a Sand Martin in a low-level, high speed pass over a convoy of ducklings – as bemused, no doubt, as I was 4000 feet above the Cotswolds (Figs 1 & 2).

Low-flying Sand Martin (Riparia riparia) with Mallards

I’d been trying to catch the Martins’ aerobatic fly-catching with no success, and started snapping the ducks more as a gesture of resigned failure. I only spotted the Martin when I downloaded the flash card.

This type of ‘buzzing’ seems to be in the Sand Martin’s nature. People on the bank get similar treatment – the bird coming from behind, passing within inches of heads, as if honing their own targeting systems.

I’d left the camera in rapid fire mode of 8 fps, so the time interval between the two photographs is known.   If we also know the length of a duck, we can calculate the Martin’s speed, in ducks per second –  or more tedious conventional units.   So:

Assuming SML = 0.3m  (Standard Mallard Length)

Time between pictures at 8 f.p.s = 0.125 s

Ducks passed between frames = 5.75 (use the grid to measure; one duck = 2 grid squares)

Bird Velocity = (5.75/0.125) = 46 ducks / second (Systeme Canard)

or  (46×0.3)                              = 13.8 metres / second (SI)

0r  (13.8×2.24)                         = 31 m.p.h.

There we have it.  Hugely practicable and useful method for measurement of the velocity of birds over water 🙂

And this is quite possibly where the Sand Martins live.  A short hop at 31 mph.

Cygnets and Swan Necks – a Case of Lead Poisoning?

Leave a comment

Cygnets on 10th May, about a week old

Meet the new arrivals.  At a pool close to where I live in the south of England, I’ve been following the progress of these cygnets since their birth five weeks ago; the  picture and the video were taken about a week after hatching.

The same breeding pair has built a nest in the same spot for the last four years: sometimes they get lucky – othertimes it looks like they go through the motions – or maybe the youngsters get dispatched by predators  before I see them.

And for sure, it’s not all sweetness and light.  Since I shot the video, one of the cygnets has developed a problem with its neck.

Swans , and particularly cygnets in their first year, are vulnerable to a host of threats: from natural predators like herons, crows, magpies and foxes;

to a bunch of man-made hazards including:  being shot at, getting caught up with fishing tackle, lead poisoning, being attacked by pet dogs, crashing into electricity pylons, and getting run down by cars.   Even well-meaning but misguided feeding can be injurious – mouldy bread is poisonous to swans.

When I visited the brood on 30th May, when the cygnets were about three weeks old, I noticed one of their number struggling to keep its head up.  That might be caused by an injury, but it’s also a known symptom of lead poisoning.

Cygnets on 30th May, one is having trouble holding its head up

Lead fishing sinker weights are banned in the UK

As Doreen Graham of the Scottish Society for the Protection of Animals said in this 2007 BBC report : “Lead poisoning is quite easy to identify in a swan because they cannot lift their heads and their heads are resting on their backs”.  There was a particularly bad spate of lead poisoning during the 1960s, although since then, with a ban on lead fishing weights, or sinkers, the Royal Society for the Protection of Birds (RSPB) believes the problem has diminished.

Lead shotgun pellets are the other likely culprit.  There are bans or restrictions on the use of lead shot throughout the UK, with detail variations across the devolved constituencies; but there’s always the danger of legacy poisoning from old pellets lying in the reeds or on the pool bed.

All swans rest their heads and necks at times – it’s how they rest and sleep; but this one’s doing it most of the time, standing out from the group:

The other cygnets appear to sense the difference,  taking the occasional peck at their handicapped sibling:

While the parents appear indifferent:

Fast forward to 8th June, when the cygnets are a month old, and at first sight there’s an improvement: it’s all heads-up in this convoy.  But on closer inspection, number 4 from the left isn’t quite right:

Cygnets on 8th June

and in this pre-roost preening session, there’s clearly still a problem:

As twilight deepens, the female swan, or pen, climbs into the nest, followed by the cygnets:

It’s easy to make up stories, but here a parent appears to attend the neck of one of the cygnets (I can’t confirm it’s ‘the’ cygnet):

And they settle for the night:

For now, the afflicted cygnet appears to be growing at a normal rate and, despite some earlier sniping by siblings, appears to be accepted by the group.   I’ll be keeping an eye on this family  over the coming weeks and update the blog with any developments.

 

 UPDATE 8 July

Happy ending.  Here’s the whole crew on 19th June – 11 days after the pics above.   All six cygnets holding their heads up high.  I’ve only just got round to updating, but if they’ve got this far they’re probably going to make the distance.  Whatever was wrong with the afflicted cygnet seems to have worked itself through/out.  (Not that these guys aren’t still in a warzone.)
