Stephen Hawking, Carl Sagan and Arthur C Clarke sat down for a chat…

Here’s some vintage video of a conversation moderated by the late Magnus Manugsson, between Arthur C Clarke, Carl Sagan and Stephen Hawking, discussing life, god, science, the universe and everything… Let me just say that again: ARTHUR C CLARKE!! CARL SAGAN!!! STEPHEN HAWKING!!! Three of my heroes of science… Has sudden geekswoon… This was recorded in 1988 – strange to think of the four here (including the distinguished Magnus, who used come into my old bookstore from time to time and was always charming when he did), only Professor Hawking is still with us, a man who was told his illness would claim him when he was still just a young man.

Climate Changed – science goes graphic

Climate Changed: a Personal Journey Through the Science,
Philippe Squarzoni,
Abrams Comicarts

climate changed philippe squarzoni abrams cover

Climate change – it’s rarely been far from ours news reports over the last couple of decades, and increasingly so in recent years (freak once in century storms happen repeatedly, is it the climate changing and did we alter it?) and just this week we’ve seen a major UN report on expected climate change and the colossal cost to our civilisation if we don’t actually take action. And that action requires a lot more than people in Western nations changing to energy-saving lightbulbs and doing their recycling more – important though those are. And this month also sees Philippe Squarzoni’s approach to this huge scientific-political-ideological-cultural problem in comics form. In pretty weighty comics form, actually – this graphic science work weighs in at well over four hundred pages. This is not a quick read, nor should it be. We’ve seen an increasing number of graphic works tackling heavyweight subjects in recent years and making them very understandable and accessible to pretty much any reader, in the case of books like this even those with only their basic high school level of science learning.

This is not exactly jumping on the bandwagon though – for starters the book first came out in French from Delcourt a couple of years back, and secondly it is quite clear not just from the length but the detail Squarzoni goes into that this is something he has been working on for years. In fact early one we see that this large, complex work actually grew out of a previous bande dessinee Squarzoni had been working on, a book on French politics. As he researched and drew a section on the environment the author suddenly finds himself coming to a halt. When his partner asks him why, he replies it is because he is using phrases like ‘carbon neutral’ and ‘greenhouse gases’. Common phrases these days, we’re all familiar with those terms, right? His partner points this out. Yes, he responds, but what do they actually mean? I’m using these phrases lifted from bits of research and re-using them in my work but I don’t really know what they actually mean, what they involve and what they portend for the future.

climate changed philippe squarzoni abrams 04

And that is, perhaps, the crux of Climate Changed – many of us know these terms, we even use them sometimes in earnest pub discussions. But how much do most of us really know about the subjects these terms cover (Darryl Cunningham, you are excused this, we know you’ve researched it!)? I mean really understand, not just a vague knowledge assembled from the BBC website articles of the Guardian, but know the various aspects of climate change and how they relate to one another – and there is not just one topic here to get to grips with, this is a real multi-headed monster, a hydra of our own making, and we need, badly need, to understand the problems, and how they interact with one another, before we can even start to consider our response to them. Assuming, of course, we have the luxury of time to formulate a response. And also assuming humanity is wise enough to decide to take relevant action. And let’s be honest, recent events where agreed restrictions on targets like emissions being missed (after already being set fairly low to begin with) or even simply ignored by some nations, that latter part is not looking good right now.

Squarzoni, as you would expect, looks at the science behind climate studies and draws on numerous experts to discuss the observed changes, relating them to historical data gleaned painstakingly from sources such as deep ice cores and tree rings, to give centuries and even millennia of historical context. Because we know the Earth’s environment is always changing – it always has, it probably always will, ours is an incredibly dynamic bio system of overlapping, interacting elements: amount of sunlight reaching the surface, various gases at different altitudes in the atmosphere, currents in the air and the great oceans, the amount of ice at the poles or on glaciers, the amount of vegetation, venting from natural sources such as volcanoes… It’s a massively complex system with each component having effects on the other, which in turn cause further effects, from increased flooding to drought, even to the fabled “mini ice ages” (think of those pictures depicting the ‘frost fairs’ on a solidly frozen Thames). And this is before you factor in human activity…

We’ve started things we cannot control…

Despite the nay-sayers (and there are still many out there, often those with a large financial stake in the status quo of consume more, make more, want more) too many of these scientific studies clearly show large increases in output from human causes which are interacting with this incredibly complex environment’s variables – the charts leap following the industrial revolution really getting going in the 1800s and the post-WWII boom accelerates this at an astonishing speed. And it isn’t just as simple as more power stations pumping out CO2, or too many cars belching exhaust gases into the air – Squarzoni also draws on economic, social and cultural elements to this debate. Advertising imagery crops up numerous times, symbolic of our modern, Western, post-WWII urge to increasingly consume, tied to the cultural ethos of a capitalism that assumes we can endlessly consume, expand, consume more, expand – more production, more buying.

But we live in a finite system, there are only so many resources, and we are using them at an alarming rate. Not just the obvious resources such as fossil fuels being depleted (and increasingly so, with developing nations industrialising) but the simple, everyday items we all take for granted. Shiny new smartphone to replace the previous one – hey, it’s tiny, it’s just me, how much difference does that make? But multiply by the number being marketed and sold across the globe, the resources used to create them (rare minerals, metals), and the energy of mining those resources then that of the factory… And you get the picture. And don’t even get started on people who drive massive SUVs around city centres, the dirty looks Squarzoni gives repeatedly to a large Land Rover parked in the middle of Lyons speaks volumes!

We continue to act like it’s nothing. And the worst thing is … it feels pretty good…”

But this isn’t some anti-capitalist diatribe – as Squarzoni points out neither he or any other person in the West has any desire to cut their use of resources from energy to affordable, plentiful food (and industrial scale agriculture is a major emitter of greenhouse gasses), losing our comfortable lifestyle where we have electricity on tap, central heating, easy transport, affordable range of clothing… He doesn’t really fancy cutting his environmental imprint to that of someone living a malnourished life in an underdeveloped nation without clean water, heating, power… And obviously none of us do. But if we can’t believe the lie of endless expansion and ever increasing consumption how do we square that circle of lowering our impact on greenhouse gases and resource scarcity with maintaining a decent standard of living? Especially as, increasingly from the 1980s on a small cadre of oligarchs and super-rich live a publicly indulgent, opulent lifestyle we’re all encouraged to want to emulate (work hard enough and anyone could be a billionaire in a mansion and yacht!). Plus why, he asks, should we ordinary folk decide to cut down on things like flights to cut pollution if the super-rich are swanning around in a Rolls Royce or a giant yacht?

climate changed philippe squarzoni abrams 02

And then there is the developing world – how do rich nations who created much of the pollution and resource consumption problem tell developing nations, no, sorry, you can’t come up to our standards, the planet won’t take it? He has to wrestle with this personal responsibility when offered a dream post, several months artist in residence in Thailand. But as he is in the middle of working on this book and researching the impact of things such as flying how can he in good conscience accept travelling there? He’d love to, but isn’t that hypocritical of him? But if he doesn’t go, but the guy down the street continues to run round town in his gas-guzzling SUV, what different has his personal sacrifice made? And, as his partner asks him, does that mean that he will never fly again? Does that mean the places they’d love to see together will be off-limits for them? What about green technologies? Are some good or just a bandwagon that some big companies (who have given more than their share of pollutants) a new, image-friendly ‘green’ marketplace to exploit? From large corporate installations to the personal, such as solar panels or wind turbines on the roof of our homes, which are actually effective, which will help do a bit to reduce our impact, and which are really just a salve to our conscience?

It’s one of the aspects of this book that makes it so accessible and easily understandable – for all the expert talking heads (which are frequent, but while slightly repetitive as a method, it is nonetheless a good way of getting information from expert sources across to the reader) talking about the Big Picture – what government, massive corporations and trans-global organisations such as the UN are trying to do (or frequently failing to do, depressingly), the sheer array of different experts required to make sense of it all (climatologists, industrial experts, meteorologists, geologists, disaster relief experts, economic experts and more) he continually comes back to the personal level, both from the personal responsibility side of things (what can we do individually? How do we encourage others to do the same so small change become large differences? Why should we if others don’t?) but it also reminds you constantly that the author himself is not a scientist, that he’s coming to this subject himself as an individual and realising from his research that, just as some of the experts are arguing, this is a subject that requires individual responses and changes in lifestyle, but also collective – this is a global problem and no nation will escape effects.

climate changed philippe squarzoni abrams 03

Even if you are lucky enough to live in a country where, say, temperature rises from greenhouse gases are mitigated because actually it makes your region a bit nicer to live in during winter months, you will still suffer because resources from oil to container vessels full of food come in from all around the world. And some of those areas may suddenly stop being so productive. Or may even be under rising waters. And then there are those rising waters – with a huge chunk of our global population (including massive Western cities of millions) right by the coast there will be problems. Perhaps catastrophes (imagine millions being displaced as environmental refugees, both in the developing world and even in the rich, Western nations – consider the thousands of poorer citizens left behind to face the waters in New Orleans after Katrina, but on an even larger scale).

On the art front there are, as you might expect perhaps for a thick tome dealing with science, a lot of graphs, and a lot of ‘talking heads’ as a series of experts from different fields – climatologists, energy experts, economists and more – to deliver large sections of information. But to stop these being too repetitive he also uses a variety of other visual tricks – his obvious love of cinema comes in handy, with frequent visual references to the iconography of film, for instance, and advertising imagery is used regularly, while he keeps grounding this vast subject in the personal with scenes from his own life with his partner and dog, as well as flashbacks to childhood (comparing his journey through life to the relentless change of the world). This also leads to a touching scene further in, as the years go past and their trusted old dog passes away we see later scenes where Squarzoni goes walking in the snow, accompanied by a ‘ghost’ dog, just the outline of his old pal by his side, not actually drawn in detail, the memory of his dog by his side. His walks through the French countryside include some quite lovely large scenes – we may be doing something bad to our environment, but it is still a quite beautiful world, he is pointing out. And in a book where there are many small, close up panels of people talking or detailed charts and graphs it’s nice to be able to breathe in the fresh air of a large, beautifully rendered scene of lakes and mountains.

It can be quite overwhelming reading – to be honest, despite finding it utterly fascinating and compelling I found it best to limit myself and read it in chunks (the layout of sections actually made this quite a suitable way to approach the book), partly not to simply overload my brain with concepts and figures and arguments, but partly also so I could allow myself time to stop and consider what I was reading. And despite what you may think, it isn’t entirely negative or doom-laden (although there is a strong pessimistic bent) – Squarzoni doesn’t restrict himself to covering everything we’re doing wrong as a species, he marshals many of those same ‘talking heads’ of his expert panel to discuss possible changes. All are adamant we have to change, and the science backs this up – despite some very shoddy media reports – as he points out when some opponents used media claims of dissent between scientists to fuel doubt about climate change a study of a decade of appropriate peer-reviewed scientific journals revealed no such disagreement, compared to about half of articles written by journalists which tried to convey there was doubt about human-made climate change – draw your own conclusions from that. And all point out that such changes are best managed incrementally – none of them want to tip the world back into economic chaos by suddenly imposing major changes without planning viable alternatives, and the quicker we start changing and adapting then the less severe those changes have to be (as opposed to head in the sand, wait till last minute then have to take radical surgery instead of holistic long term treatment approach). And all agree that such change can’t simply be forced, the democratic principle has to be used, people engaged in the debate, informed and give consent (and indeed to pressure) to their political leadership for changes.

climate changed philippe squarzoni abrams 01

It’s a fascinating, thought-provoking work, well-researched (coming with a good bibliography and list of various experts quoted and other resources for learning more), and the graphical approach makes the task of assimilating the mass of complex material much simpler for the reader. Squarzoni is also to be commended for taking in the large range of industrial, economic, social and cultural aspects to climate change and relating them to one another, in addition to the perhaps more obvious issues of just what sorts of waste we’ve pumped out relentlessly into our own biosphere without thinking about what it was doing. This isn’t a single problem, it’s a series of multiple but interconnected problems, some exacerbated by natural causes, but most from human causes which many simply don’t think about much, beyond the afore-mentioned changing to energy efficient bulbs. But as one expert points out in the book, the Earth has it’s own timetable – change is happening and most consider we’ve gone beyond the point where we can stop even more change coming. But we can adapt to it, we can limit the changes, manage them better, if we’re informed and able to make those decisions (and the drive to see them through – actual action, not just fine speeches from politicians or ads telling us how much giant oil companies care about the environment). And as with many problems, reading about them is a fairly good place to start… Don’t be put off by the size of the book or the heavyweight subject matter – as I said Squarzoni does a remarkable job in putting across the subject and also personalising it (it also arrives bearing plaudits and awards from the European scene), and let’s face it, as arguments erupt already over this new UN climate report out this week, we could all do with being more informed on a subject that affects every single person on the planet.

Cosmos, the next generation…

Space has always fascinated me, perhaps not surprisingly as I was born at the peak of the Apollo programme, just a couple of years before Neil Armstrong’s giant leap on the Moon. I had my little astronaut suit to play in, repeats of the original Star Trek, Doctor Who, UFO, numerous other Gerry Anderson shows – space and an optimism in the future and in our ability to learn to use our own brains and science to better humanity were popular topics (sadly so much more pessimistic today for many). I was a child of the Space Age and then grew up in the early Information Age, I had a stack of astronomy books on my shelves even as a kid (reader then, as now). And then there was Cosmos and Carl Sagan on the television. I read and read, by the time I was 9 or 10 I could tell you the difference between a Gemini and a Soyuz and an Apollo capsule, I knew who Kepler was and how his mathematics shaped our understanding of our solar system.

Carl Sagan – Cosmos (Trailer) (1980) from Xhulian Traja on Vimeo.

I loved my books, but in Cosmos I could see it all – a history of science here on Earth and how it applied to our expanding knowledge of the universe itself, not just showing fascinating glimpses of distant creation, but putting it into a context of accumulated knowledge. I didn’t  realise that aspect of it until I was much older, but subliminally the message was received and somewhere inside my young brain, absorbed and applied and forever after I have taken simple delight and pleasure in finding links between pieces of knowledge, that wonderful moment when you realise that something you are reading or watching relates to some other subject you read previously, connection and connection and connection. I still take pleasure when that happens today, and it was a lesson Sagan taught in the original Cosmos, that knowledge is one thing, but the ability to step back, place that piece of knowledge into context, was even more important, because then you start to assemble the jigsaw that shows The Big Picture. We never actually finish that particular jigsaw, because none of us is omniscient, but there’s so much pleasure to be had from assembling and connecting those pieces…

The original Cosmos also helped me humiliate an utter prig of a senior at my school, who tried to make me and my friend feel small and stupid. Back when there was a single BBC Micro for the whole school we were busy programming on it when this senior barged in with a friend, demanding we stop and they get to use it because their science teacher had an “important” programme that “we wouldn’t understand”. I asked what it was, and in a very condescending tone he told us it was to do with Kepler’s laws and we wouldn’t know anything about that. I proceeded to outline the main points of Kepler’s laws and observations and place them in their historical context for good measure. I would only be about eleven or twelve, he was about fifteen. I watched him deflate and become utterly humiliated as it was clear to all in the room that Mr Superior knew less about this subject than a boy did. Thanks to Sagan and Cosmos, where I learned of it then, me being me, I had followed this up by reading more about it. Learning is our friend. And sometimes we can use it in interesting ways, to beat an intellectual bully. Satisfying in itself, and also taught me a lesson too – there’s always someone who knows more than you do…

Sagan’s books and his Cosmos series had a huge influence on me. I think his series and the programmes of the great Jacques Cousteau taught young me an enormous amount about science and what Sagan called “the awesome machinery of nature.” My brain was never terribly good with maths, so studying science at university was never likely, my thoughts were more wired to the arts and language, and I have no regrets over that because I am forever in love with words, but they, and my piles of related books, left me with a huge fascination for an and appreciation of science and learning. And space exploration and astronomy especially, but again there’s that thing about learning being linked – learning about theories of how the other planets became the way they are prompted me to read some geology to understand this better. As a kid I also loved dinosaurs (which wee boy doesn’t?) and of course that linked with geology, which also lead into theories of evolution, which in turn lead to books about why it is humans can think, have language, create abstract thought, the very faculties that allowed for astonishing things like space exploration. There it is again, link, after link after link, all adding layers of context to what was learned.

And so this evening the much anticipated new Cosmos made its UK debut, with an introduction by President Obama, no less. Of course dear old Carl has been gone for a number of years now, but his influence is still felt, from his own opening narration and choice of similar location to that he used for his original introduction to the use of the ‘spaceship of the imagination’. And the new presenter, Neil deGrasse Tyson also embodies another link to Sagan – a joyfully personal one too, as he recounts at one point how as a seventeen year old student Sagan had invited him to visit. He arrived during heavy snow and Sagan talked to him, showed him his lab and offices at Cornell and presented him with a signed copy of one of his books (which he still has), an encounter which enthused the young man not only to a career in science but to emulate his role model in communicating science to a wider audience, to let everyone share in the knowledge and consider its implications and possibilities, which is important given how such matters often affect all of civilisation.

And so the new show’s first episode this evening… The format is similar to the classic Cosmos, the mixture of astronomy but interspersed with history, both human history of ideas and understanding and the deeper history of our own world, solar system, galaxy and universe. Again, context, links, without which facts don’t mean much. Of course the graphics are vastly superior to the effects the 1980 show could ever hope to create (although back then I still remember marveling at them). But the most important quality, more important than the scientific facts, the history, the learning, was something Sagan gave me in the original, Cousteau did with his shows, Arthur C Clarke did with his books – and that is the quality of sense of wonder. Simple as that – a sense of wonder that makes you feel like a bright eyed child again staring at the stars and imagining and dreaming.  And yes, the new show had that sense of wonder.

The World Outside My Window

This is simply stunning, brief though it is, a timelapse of footage shot of our world rotating below the International Space Station (ISS), all shot in beautifully crisp HD, creating some wonderfully sharp, clear images of our planet from several dozens miles above the atmosphere. Best viewing experience is to select the fullscreen option and just glory in it for a few brief moments…

I’ve been eager to see Gravity for some time – Alfonso Cuarón’s take on PD James novel The Children of Men was a remarkable and powerful movie. This, originally, was to be his ‘quick’ movie after that long slog, but ended up taking several years instead, not least because they had to invent whole new ways of shooting to create the remarkable visual effects. Creating the effect that a person or a ship is in space is not new, of course, it’s been done with varying degrees of success for decades on the big screen, from the realistic approach of 2001 to the scientifically silly but visually wonderful style of Star Wars. Gravity follows more in the realistic mode of 2001 – no deep bass rumbles of mighty ships in the void (where there isn’t any atmosphere to transmit sound) and no sudden and graceful movements of winged craft that fly like planes (even though that is not how you maneuver in space), instead the only sound is inside your helmet or radio, movement is in line with Newton’s laws and the way a body travels in a gravity free, airless environment.


What it does differently from 2001 and other films which tried to portray space exploration as it really is though, is the depiction of being in a zero-gee environment. Cuarón and his team had to really battle to come up with filming systems to allow them to make their actors look like they truly are in a gravity free environment, and ye celluloid gods but it paid off. In fact, and I say this as someone who has been fascinated by space exploration since he was a very small boy, studied it, read about, imagined it, this paid off so well that you could be forgiven for thinking it was actually shot on location in Earth orbit. Yes, it really is that realistic looking. And it is also utterly ravishing, visually, right from an opening shot of a glowing Earth below a team of astronauts from a Shuttle working on the Hubble Space Telescope. Bullock’s specialist, a scientist brought into NASA to work on this particular upgrade because of her technical skills but not really an astronaut (apart from basic training), while Clooney’s veteran astronaut on his final flight is happily trying out a new design of MMU (Maned Maneuvering Unit – a jetpack for space, effectively) and flitting around the team. The glowing Earth below them fills the cinema screen and is simply beautiful, awesome in the proper use of the word.

But while the visual aspect of Gravity is remarkable and stunning (even the 3D, something I generally dislike in live action films, is excellent and worth the usual eye strain and headache) this isn’t just an effect fest, there is a story here and it is one which is incredibly tense and indeed intense, seriously gripping the arms of your chair stuff, right the way through. When Mission Control calls a warning to the team that a satellite has been destroyed and the debris is sweeping around the orbit towards them events rapidly spiral out of control into a desperate, against the odds attempt at survival.

gravity movie 02

And survival in an environment no human – no creature on our planet at all – evolved to survive in. It’s a deadly environment that we’ve somehow pushed ourselves and our technology to allow us to live and work in over the last half decade (and it’s worth remembering that in thousands of years of human history it is only a few dozen people over the last sixty years who have gone into space). And it anything goes wrong it can be fatal so very, horribly quickly. Even tiny pieces of debris, even just a bolt, travelling at twenty thousand miles and hour will have such kinetic force it can tear through a ship or a space station like an anti-tank round. And all of a sudden an intricate ship or station, assembled from so many precise components and painstakingly engineered and constructed to be just right to support human life in this environment is turned into Swiss cheese…

gravity movie 04

I won’t ruin it for you by expanding any further on how it develops from this accident. Suffice to say it is edge of the seat stuff, beautifully depicted, while the interaction between Bullock’s damaged scientist and Clooney’s veteran of the space programme, even in desperate straits, is perfectly handled (Clooney projects that image most of us have of the calm, unflappable NASA old school astronaut who takes the most catastrophic failures in his stride). This may be vast scale, big-screen, effects-laden storytelling, but it does not neglect either story or character and I found it profoundly satisfying on the emotional level as well as the spectacle. There are some nice nods to other iconic moments from space films tucked away in among the tense moments – a scene where Bullock floats in an airlock, shimmying out of her space suit recalls Barbarella, Bullock in vest and shorts in the space station reminds me of Ripley in the shuttle at the end of Alien, Bullock again floating, exhausted, in an airlock, the sunrise from space glowing through the window port as he floats in zero gee, curling up almost foetal after surviving one part of her ordeal, the cords around her like an umbilical coil, making her seem at the same time both childlike, a newborn and at the same time recalls the ‘star child’ from 2001 and the transformational power of such experiences and travel. It’s gripping right to the very last and as I said the visuals are simply breath-taking – this is one you want to see on the big screen, not on DVD later on, watch it on a big cinema screen and let yourself be drawn into it until you feel you’re there, floating above the world. An utterly remarkable piece of film-making.

gravity movie 03

And I have to add, on a personal note, those visuals played right into my life-long fascination with space travel; that screen-filling vista of the Earth revolving made my pulse race, just as it always has since I was a kid, at the thought of going into space. I had the same feeling watching In the Shadow of the Moon a few years ago; those Saturn V rockets lit up and my pulse went with them, the same excitement and longing I’ve had since I was five years old, in my little astronaut playsuit and helmet, sitting in an empty box for a spaceship, with an imagination as big as the universe. And even after watching a film like this showing the dangers I know that if I were offered the chance I would go in a heartbeat, that it’s the trip I have always wanted to make since I was that wee boy in his astronaut suit, playing and dreaming; I’m literally a child of the space age, born at the peak of the Apollo programme, and I’m forever disappointed that I’ll almost certainly never get to experience it first hand…

You Are Here…

An infinitesimal dot in a vast space, containing, as the great Carl Sagan once said of another famous image from our exploration of space, the Pale Blue Dot image, every single person you ever knew, your mother, father, brother, your grandfather, his father back to the earliest proto human, every cat, dog, fish, bird, every beggar and king, every famous musician, every humble artisan, all lived on that dot. That’s home. Now Cassini sends us this spectacular image from Saturn, the crown jewel of the solar system, the Earth, a bright, blue dot (arrowed in the pic) glowing in the vast distance, millions of miles away while the magnificent rings of Saturn wheel above.

the earth from Saturn Cassini

Every person, everything we’ve ever done is on that dot, from the first single celled creatures through the great dinosaurs to us, all contained inside that glowing dot. And yet look at this picture, look at how far we can reach, further than anyone in thousands of years of human history – look at how far we can reach when we put out efforts and those big brains evolution gave us to some wonderful effort instead of squabbling and fighting among ourselves on that same small dot. When we’re not doing that, this is the kind of thing we can accomplish, and it is magnificent. A little reminder as we see endless bad news of wars, disasters, economic ruin and more every night on the news that actually we are remarkable, our species built this clever probe, worked out a complex flight path around celestial bodies at huge speed, swinging around gravity wells and did so with such precision it can send us back images of our own world as seen from the rings of Saturn and we can share it at almost the speed of light through fiber optic networks of computers across that little globe, instantly.

The Earth is the shore of the cosmic ocean. Recently we’ve waded a little way out, and the water seems inviting...” Carl Sagan.

The Pale Blue Dot

During the epic Voyager missions, after one of those innovative little mechanical explorers had finished with its primary mission to give us our most astonishing close up encounters with the most distant worlds in our solar system in a detail that Galileo and Copernicus could never have dreamed possible, it was re-tasked and reprogrammed to turn around to look back into our solar system from the cold, dark edge of our own little stellar neighbourhood. The late, great Carl Sagan was one of those who campaigned for this to happen – no small feat given the codes to reprogramme the distant probe would take hours to reach it even travelling at the light speed of radio waves, so far was it from home now, and there was no true scientific knowledge to be gained from this move.

Sagan, however, always understood that science has to appeal to both the heart as well as the head, emotion and intellect, and be able to make everyone grasp why it was important to us. The spacecraft was turned and took what is now known as the family portrait, a view of most of the planets in our solar system, a perspective no-one in the entire history of humanity had ever beheld before, a real “going where no-one had gone before” moment. In that family portrait is a pale, blue dot, not even an entire pixel in size – our world, the Earth. As Sagan put it, everything any of us has ever known, every person we have read of, every person who built a monument we’ve gazed at, everyone we have ever loved and all those who came before them, right back to the emergence of our ancestors out of ancient Africa’s cradle to start out human journey, every one of them, peasant and king alike, lived on that tiny dot. Joel Somerfield’s animation is very short but celebrates that moment, using the words of Sagan, a moment when emotion and science, heart and intellect, gave our species a new perspective on the majesty of creation and our own place in it, just a tiny mote floating in the glow of the sun, miniscule in astronomical terms, fragile, but never, ever unimportant, but a wonder in a sea of wonders, a haven of spectacularly diverse life. Our home.

Turing 100

Professor Jim Al Khalili, ERS Turing lecture 02

(Professor Jim Al-Khalili signing books after the Turing lecture)

On Thursday night I attended a special guest lecture at Edinburgh University’s George Square Theatre, organised by the Edinburgh Royal Society, with author, theoretical physicist and broadcaster (he’s presented some excellent science documentaries on the BBC and C4) Professor Jim Al-Khalili. It was part of a series of events going on this year to mark 100 years since one of the great minds of the 20th century, Alan Turing, was born. I’ve always been a huge admirer of Turing – the father of computing and Artificial Intelligence, working out systems on pencil and paper before he and his colleagues, along with the GPO’s hugely gifted electronic engineer Tommy Flowers, created the world’s first electronic computer, a device so secret it was classified for decades while publicly others took the glory for ‘first’ computers later. Because they used this to help break the Nazi Enigma codes, without which the Second World War might have taken many more years of hard struggle and countless thousands more lives. He and his Bletchley Park colleagues were, in a real sense, war heroes, just not the sort who carry a rifle into combat, but utterly essential to the defeat of the Axis and the safeguarding of free civilisation. Turing was also a gifted visionary who was able to conceive of using science and mathematics to model thought processes years before others, giving new pathways to exploring both computing technology then emerging as well as understanding more how the incredibly complex human brain works and how that could be applied to machines, if they too could be make to think, each step along that road revealing more about the astonishing complexity of our own minds than that of our complex technology.

Sadly in the 50s Turing, a homosexual man, was arrested, homosexuality being illegal at the time, stripped of his security clearance despite his wartime record and given a choice of chemical castration or prison. He took the former but was never the same; depressed he took his own life with an arsenic laced apple. So little appreciation from the government of the country he had helped save with his genius and dedication and a reminder today when we see some clergy and politicians making unsavoury remarks about gay people how such comments can lead to attitudes and actions which can take lives, to the detriment of all of society… Turing remains one of my scientific heroes, though, and I was pleased that a public campaign a couple of years ago resulted in the then Labour government of Gordon Brown publishing an official apology for the way Turing had been treated back in the Britain of the 50s.

The Big E over the Big Apple

With the shuttle programme – and NASA’s ability, for the moment, to send manned missions into space – now grounded and the surviving spacecraft being sent to various museums around America today there was a very special moment as a modified 747 carried a very special shuttle flying low over New York City for everyone to watch. The spacecraft was the Enterprise. The ending of the shuttle programme is much like the ending of Concorde for many of us – when we were kids they were the future, now they are history and that would be fine, it would be natural, if they were retired to make way for the next generation of craft to replace them, but they’re not. We’ve stepped backwards, it feels, become smaller. But for a final hurrah this was a remarkable one, the Enterprise, her very name resonates for many of us, flying over New York, captured here with Lady Liberty and the Empire State in the frame by Bill Ingalls:

What a remarkable shot, a couple of the great world landmarks with a piece of flying space exploration history. Enterprise was named after NASA called for a public vote to name the first spaceship; the geek community, of course, got together and made sure to vote en masse that she would be called the Enterprise, because she was the first of a series that would boldly go… Enterprise herself never brushed against the hard vacuum of space though, she started her career at NASA riding piggyback just like she was today – she was designed to test aerodynamics, a bit of a new area for spacecraft design at the time because most were odd shaped objects on the end of a rocket but the shuttle, she was meant to fly back down from orbit through the atmosphere like a conventional plane, hence the tests. As a boy I followed the emerging shuttle programme and remember well watching news reports of the Enterprise’s flights paving the way for the first full shuttle launch.

As a wee boy raised on repeats of the classic Star Trek it made me happy to see a real spacecraft being named Enterprise and, Americans being rather good at marking big occasions, when she was first revealed to the public Trek creator Gene Rodenberry and many of the original cast were there to wish her good skies, way back in 1976 (pic below and following borrowed from

And here three and a half decades or so on is one of those illustrious crewmembers of the fictional USS Enterprise giving the Vulcan salute – live long and prosper – to his old friend, the shuttle Enterprise, as she heads for the Intrepid Sea, Air and Space Musuem in New York. Rather fitting she will be near the USS Intrepid, which any old Star Trek hand knows was the name of one of the other Constitution class starships in the original Trek, the same class of vessel as Jim Kirk’s Enterprise (Intrepid being crewed entirely by Vulcans, if my memory serves):



As I said, like with Concorde, it feels wrong to know that the shuttle are gone, that something that promised the exciting future of space exploration to a young boy is now a historical artefact in a museum and that we didn’t mothball them to make way for a new generation of faster, bigger, more efficient spacecraft. Still, one of these days there will be another Enterprise, I am sure. Larger, with a greater range, this Enterprise A, B or C ships will boldly go further… As Captain Jean-Luc Picard himself once noted when asked if they would ever build another Enterprise “plenty more letters in the alphabet”.



One day, another Enterprise, please, make it so…

Reviews From the Past: How To Build a Nuclear Bomb

Another of my almost-lost reviews from years ago – tis review of Frank Barnaby’s science/history book was first written for The Alien Online back in November 2003 and was quite pertinent at the time as rows over the claims for WMDs in Iraq pre-invasion then the failure to find any post-invasion and the idea that we had largely been lied to by governments to justify the war was growing.
How to Build a Nuclear Bomb and Other Weapons of Mass Destruction

By Frank Barnaby
Published Granta, September 2003

How I learned to fear the bomb and start worrying more

Okay, first off, despite the cheeky title this is not a manual on the construction of thermonuclear devices. So those of you who were technically minded and looking for a project to occupy you over the long winter nights can stop reading now. What this little book actually does do is act as a handy-sized, easy to understand primer on Weapons of Mass Destruction – those WMDs all the cool kids are talking so much about these days.

Barnaby, a nuclear physicist who worked at Aldermaston, amongst other places, lays out concise explanations in a language easily accessible to the layman, describing each of the three main WMDs: atomic, biological and chemical (now you know where 2000 AD’s ABC Warriors got their name from).

The section on each type of weapon system is then broken down into brief overviews explaining the history of the weapon’s development, how they work, how they can be deployed by governments or small groups, what effects they have and, even more depressing, the history of their actual use, from chemical weapons on the fields of WWI Flanders to nuclear annihilation over WWII Japan.

This is not to say that Barnaby is an alarmist. Far from it; in fact he seems to have written this sensible book in order to counteract the souped-up hyperbole of the mass media in our post 9-11 world and the dreadful spin (if not actual misleading or even lying claims) about WMDS from governments. He has aimed to cut through this and produce an effective introduction to let the thinking person understand some of the real history, possible effects and uses of WMDs. In this respect I’d say he was extremely successful. For example, I now know that WMDs are not in fact invisible. Which does make me wonder why the US/UK can’t find all those ones in Iraq.

Although very informative, this book is, almost by its nature, disturbing reading. Describing how simple it is for someone to create chemical or biological weapons is frankly terrifying, and the example of the Tokyo subway attack using Sarin (the group responsible also had produced Anthrax) highlights the danger. The fact that immensely wealthy and powerful international pharmaceutical companies have used their might to stymie effective checks on production facilities in case someone is using them to secretly create bio or chemical weapons is even more alarming. There is no international system of checks – as exists for nuclear facilities – because the companies are too worried about possible industrial espionage and are prepared to put the lives of others at risk to protect their profits.

This is unlikely to be of surprise to anyone who has followed these same companies’ years of trying to block cheap, generic drugs to third world nations, but it is still more than a little astonishing that even in the current political climate there is no body to check up on chemical and biological facilities world wide. Given their history – look how many such weapons were created by IG Farben in Nazi Germany alone – you’d think the industry would be a little more safety compliant.

There was one aspect of this book that was even more horrifying and disturbing than this however. This dealt with the history of the deployment and use of WMDs. Often by the same ‘responsible’ governments who now act out military adventures to supposedly save civilization from madmen armed with WMDs. Chemical agents dropped in Vietnam, gas weapons used by Germany, Britain and France in World War I and, of course, the nuclear fires over Hiroshima and Nagasaki that burned the horror of WMDs indelibly into the public mind for all time in much the same way as they burned people’s shadows into the walls.

And before anyone argues that these events are being taken out of historical context, Barnaby discusses the vast destructive arsenals Russia, Britain, America, China and France hold to this very day and are reluctant to get rid of, while trying to ensure other nations do not possess similar weapons; although to his credit he does not take a political stance on this, merely reports the facts.

So, yes, this is disturbing material, but if you follow current events then you should know this stuff so you can try and cut through the spin and scare-tactic headlines. Information is a weapon every bit as effective as WMDs and its one weapon we should all have access to.

Reviews from the past: Living Dolls

This review was first posted on The Alien Online back in May of 2002. By coincidence it was the second pop-science book on the subject of historical automata I posted on there within a short space of time, the other being Tom Standage’s fascintaing book on the famous Mechanical Turk (reposted here). Wood’s book is more wide ranging though, going through a number of famous historical automatons across the centuries, right through to modern day scientists working in advanced robotics, along the way taking in the birth of modern cinema, stage magic and some of the figures who moved through both fields like George Melies, magician, showman, pioneer of early cinema and a displayer of automata, even taking in remarkable humans who some believed were really automata.

Living Dolls by Gaby Wood

Machines which mimic human life, humans who appear as perfect doll-like automatons – not science fiction, but history

Typical – you wait ages for a book that deals with historical automatons and then two come along at once.

Anyone who has read the recently published the Mechanical Turk (see earlier review) by Tom Standage will be at least partially familiar with some of the subjects in this new book from Observer writer Gaby Wood. Understandably The Turk itself commands a fair chunk of the book – it is, after all, one of the most famous attempts to counterfeit life artificially. The question here is, does Living Dolls contain enough new material to make it worth reading if you have already perused The Turk? Personally I think the answer is a resounding ‘yes’.

Living Dolls eschews the in-depth concentration on a single strand of automata for a more general and wide-based historical overview. Wood certainly covers many of the same areas as Standage – Vaucanson’s mechanical duck, his magical flute player and of course The Turk – but she is preparing her grounds for a somewhat more anthropological approach. Her broader overview allows her to examine what it means to be human or machine and how the lines have been blurred by successive generations of mechanicians, scientists and illusionists (not all as different and occupation as you may suppose). Wood carries the reader through the wonderful devices of the 18th and 19th century with a journalist’s understanding for the human angle, affording us a more empathic approach to this fascinating subject than Standage, with a fine eye for wry amusement along the way (for instance the mechanical child who writes essays at his desk and occasionally scribbles “I think therefore I am, I do not think, do I therefore exist?”).

Wood includes in her definition of artificial life the creation of cinema in the 1890s and also the first phonographs, with excellent chapters on Edison and George Melies. It is hard to imagine for us now, but when Edison first created the phonograph he had inadvertently given away one of the defining characteristics of humans – speech and language – to a machine. Moreover, this machine could store a voice, playing it back long after the speaker has ceased to exist – this was indeed a marvel of the age and also deeply disturbing, especially when fitted inside Edison’s talking doll. Melies, a great stage illusionist who ran the Robert Houdin theatre (the magician and automaton maker who gave Harry Houdini his stage name), uses the early cinema to create new takes on human forms. One of the first to realise he could use the new medium for magical effects and tricks, Wood argues that Melies, by making what appear to be humans perform actions impossible in real life, had actually created a new type of simulacrum. In an age of virtual reality, this is certainly a subject to be considered and it is fascinating to see the precursors to our modern conundrum with technology and The Real back in the age of steam.

The final chapter deals less with the mechanical and more with difference. Wood brings us into the early twentieth century and the heyday of the travelling carnival and all-American freak show. We are introduced to many fascinating and richly colourful characters, notably the Schneiders, who appeared under the stage name of the Doll Family. This was a travelling act of a family of midgets, who unlike some small people have limbs that are in proportion, making them appear like either children or miniature versions of adults. Is this straying from the subject, fascinating as it is?

Wood, successfully in my opinion, argues that in a fine historical reversal the Doll Family were often perceived by curious audiences as simulacra. No real person could be this size and in proportion, so they must be clockwork dolls or automata of some sort. We have moved from the public gasping in admiration at mechanical devices counterfeiting life so well they believe a human agent must either be inside or controlling them to an era where they believe small humans to be unreal, mechanical concoctions. In an era of psychoanalysis this fits in perfectly with notions of the Uncanny and the all-too-human fear of the Other. The Dolls, especially Harry, appeared in many Hollywood films and were well loved. Tod Browning, who began working in these same carnivals went on to direct Lugosi in Dracula before casting Harry and other real life carnival performers in his astonishing film, Freaks. A fascinating mixture of mechanical (the moving image and recorded voice) and people very different from the ‘normal’ range of humanity – what is human? What is normal? How can we consider if a machine has life or thought if we are so prejudiced against other humans who look different? In a wonderful personal coda to this chapter Wood is examining archives in Florida, where the Dolls retired. After reading Harry’s obituary – he passed away in the 80s – she decides to drive past the address listed as his last home, a kind of pilgrimage. She is shocked to find the Doll name still on the mailbox and further surprised to find Elly – Tiny Doll – still in residence. It is a wonderfully personal and warm moment, a piece of the history she has researched, still here, no longer a chapter in a book but a breathing, feeling person.

The very last short chapter takes Wood to Japan to observe the latest in robotic technology. In another amusing twist she finds that Professor Takanishi has constructed an artificial flautist, completing a circle from the eighteenth century to the twenty-first. She asks him if this in tribute to Vaucanson’s famed eighteenth century mechanical flute player. Takanishi answers in the negative. In fact he is of the opinion that a mechanical flute player is so difficult to create that Vaucanson could not possibly have constructed one nearly two hundred years ago. I share Wood’s ironic amusement at this modern scientist’s lack of history in his own subject of research.

As with Standage’s Turk, Living Dolls is a book of wonders, from past to present. Little reminders that the mechanical miracles that are now commonplace in our modern world are not new, and debates over the status of humanity and intelligence and machines have been with us for a long time. I found The Turk to be a fascinating and absorbing book, but Living Dolls has perhaps a more human, warm and personal touch to the subject. Oh, why not spoil yourself and read the pair of them!? Then the next time you watch Data in Star Trek TNG debating if he is really “alive” you will be able to appreciate the rich history behind his Pinocchio-like dilemma.
