Breaking the writing rules

Who wouldn't want a doorway that looked like this?
Last night I had a quaint dream. Don't stop reading - I know the rule is to never tell other people about your dreams because it's so BORING, but the whole point of this post is about when it makes sense to break the rules.

In the dream I was helping out a company whose sole product was doorways designed in the style of the old Foyles building in Charing Cross Road (don't ask). They were worried about their advertising, which consisted of half page magazine adverts that were totally full of text apart from a backdrop of a Caribbean beach.

Now, one rule of advertising is Don't use too many words. People switch off. Get your message across with images and a few snappy words. (You can have small, secondary text to give follow-on information, but the main message should be short and big.) If you look at adverts on Tube stations these days, for instance, that's generally the case. But when I regularly caught the Tube when I worked at Hatton Cross, one company thought differently.

The adverts were for a Russian restaurant, and they reasoned that people waiting for a tube have nothing else to do but read the adverts - so why not give them something more significant to read? So their adverts had loads of text. And it caused a storm. People loved it. (And briefly other advertisers did the same, though they seem to have forgotten how effective it was now.) Rules in writing are all very well, but sometimes the best result is had from breaking them. Every great writer does this. It doesn't mean you  can write well without knowing what the rules are - but if you know what you are doing, you can consciously break those rules to superb effect.

We had a good example of this at the popular science book writing masterclass a couple of weeks ago. At the end of the event, a panel, including me, were giving feedback on book ideas. What we said several times was that the idea being presented to us was really just a collection of information. To make a good popular science book it needed an arc - an overarching development of a theme across the book. And then someone came up with an idea where each chapter in her book was effectively a separate story with no real connection, apart from the device that was used to link them together. The person with the idea was hesitant, because there was no arc - this was a separate set of individual stories. And the answer was - it's fine to break the rules. (I think I actually said 'There are no rules,' which isn't true, but I meant there are no unbreakable rules.) Here it worked because of the special nature of that linking device.

So the advice to writers (and I think this applies to both non-fiction and fiction) is simple. Learn the rules. Be aware how they apply to your book. Use them conscientiously. And then be prepared to ignore them if it works better that way.

Not in my global village

I have just read the 17 May edition of New Scientist. (My reading filing pile is somewhat random.) In the leader we are told how the illegal export of rhino horns, ivory etc funds terrorist groups like Boko Haram.

Fair enough. Then comes this statement: 'When it comes to wildlife crime it is easy to point the finger at Chinese demand for ivory, rhino horn and tiger penis while forgetting that all consumers contribute to some extent.'

What?  I'm sorry, I find this extremely offensive. You can't make a blanket statement like that without evidence, and a science magazine should know better than to do so. I simply don't accept that I, as it later puts it, as an 'affluent consumer', 'encourage the slaughter of endangered animals.'

I think the slaughter of these animals and the uses of their materials in what is nothing more than a pathetic attempt at magic is unacceptable. I don't in any way support the practices in which they are used. It is the people who believe in the magic and who pay for this indefensible trade who are to blame, full stop.

This is the concept of the global village gone mad. The world is not a village. I do not offer any encouragement to this activity, and for New Scientist to suggest that I do is the worst sort of appeasement. It's time people took responsibility for their own actions, rather than the responsibility being displaced on the rest of us in some kind of misguided internationalism.

Why I've ventured into eBay

One of my (many) favourite parts of the wonderful Buffy the Vampire Slayer is when they need a mcguffin called an Urn of Osiris. One is duly obtained and when someone asks, amazed that this rare item has been so quickly found, the answer is something to the effect of 'Oh, I got it on eBay.'

I have a mixed relationship with selling books on eBay. I used to regularly sell my Organizing a Murder ebook of party games that way, selling at least a copy a week, which worked wonderfully well as there was nothing to post (and I got really happy feedback). Eventually eBay stopped me from selling it because they said I didn't have the rights to do so. Despite many attempts to point out that, as the author, I had every right, I never got anywhere - any attempt to get an non-robotic response out of the supposedly human customer service team at eBay is a nightmare. I think they have now banned selling e-products.

I've never really bothered selling physical books this way, but I thought as an experiment I would try selling a signed copy of Dice World with a personalised dedication. It's on this week - you can take a look here - and at the time of writing it could be yours for £1.04 (UK only, I'm afraid). I've no idea what will come of it, but I think in the writing business you have to be constantly experimenting with different ways of being in contact with the audience, and I hope this will be an effective one. We shall see! I will update the post with the outcome after the event.

* UPDATED 2 August *

The auction has now finished - and the answer based on this very small experiment is 'Probably not worth it.' The book received 8 bids and sold for £4.10, where I would normally sell them at a speaking event for £8. (To put it into context, I have to pay £4.50 to buy them from the publisher.) So not something I'll try again for the moment - but worth a try.

Stalking Mr Muybridge

One of my early popular science books, The Man Who Stopped Time, was on the photographic and moving picture pioneer, Eadweard Muybridge, who did most of his work in Pennsylvania and California, but who was born in Kingston-upon-Thames. Here's an account I wrote at the time of hunting for Muybridge in Kingston.

When getting under the skin on Edweard Muybridge you can’t avoid Kingston-upon-Thames. It inevitably means regular visits to the North Kingston Centre, an unfriendly, echoing civic building tagged onto a school, which houses the local history room. The room, entered through a strangely bunker-like door, resembles every reference library you have ever been in. Old well-used tables, a slightly musty smell and a few modern contrivances – PCs, photocopier, microfilm readers – sitting uncomfortably alongside the huge bound volumes of the local paper. Very friendly and helpful staff, though.

But that’s a little world of its own as is the Kingston Museum, with its dramatic Muybridge exhibit taking up a sizeable corner of the small, unassuming building. They are great sources of information, but they aren’t the Kingston that Muybridge knew. However, three significant sites remain for the Muybridge groupie – the King’s Stone, the Muybridge family house (and workplace) and the house he spent his last years in after returning from America.

 The King’s Stone, that one-time English Stone of Scone, later used as a mounting block in the marketplace, stands in splendid isolation outside the ugly curve of the Guildhall, a circa 1930s monstrosity of brick and verdigris. (The verdigris may be a false memory.) The stone itself is set around with protective railings, in a surprisingly pleasant tree-lined area with bench seats, a platform over the river that disappears underground just before reaching the site.

They’re a little faded now, but you can still make out those early English kings’ names, including the two distinctive ‘Eadweard’s that almost certainly inspired Edward Muggeridge to start his gradual transformation into the more dramatic Eadweard Muybridge. And surprisingly, the inset coins of the period are still there too. But the real surprise was to look up and realize why the King’s Stone was so likely to have influenced Muybridge when it was put in its fancy new setting in 1850. From the stone there is a clear view of the upper windows, the domestic windows, of the Muggeridge property. He could see the stone from his family home. (The stone has been moved a little since 1850, but was outside the old Guildhall on a very similar spot).

Is Eadweard’s birthplace a museum, a National Trust, preserved in aspic view on this unique man’s origins? Not exactly. Crossing the High Street from the Stone takes you to a house that is actually significantly more handsome than its faded state and commercial use suggest. Downstairs, in Eadweard’s day, was the family coal merchant and corn chandlery. Handy for the Thames, running at the back of the property, it would have been  bustling, noisy and more than a little dirty. Now it’s a computer shop. Not a glossy chain store but one of those little places that rarely seem to have any customers, but somehow manage to hang on at the edge of the hi-tech revolution with a combination of bravado and individuality.

The upstairs, what would have been the family home, is now the offices of a business consultancy. Filing cabinets and a mix of modern and older office furniture sit in the Victorian spaces with the usual discomfort of a converted older building that hasn’t had a huge amount of money spent on it. But the biggest change is at the back.

Here, where the young Eadweard would have played among the coal heaps, where the Muggeridge yard would have stretched down to the ugly but practical banks of the suburban Thames, are now two mid-rise blocks of apartments, cutting off the house from the river, dividing the past from the present. I’m sure they’re meant to be stylish, but to me they just looked sad and out of place – but I was seeing them through Muybridge eyes.

And so to Liverpool Road, and Muybridge’s last home, from the place he was born to the place he died. I decided to walk and it proved quite a journey – if not quite a lifetime, the trek seemed to go on and on, through the town centre, then those scruffy streets that lurk on the edges, where everything is a bit run down, before appearing to leave Kingston entirely. At last, (long last) I was into classic leafy suburbs, the sort of streets where there’s never quite enough space for all the cars, and onto Liverpool Road itself. I’d got a blister by now and was feeling noticeably sorry for myself, so it’s no great surprise that I entered Liverpool Road and started to suspect that the solid villa Muybridge had lived out his life in was long gone.

For house after house there was a string of those 1930s brick non-entities that fill so many suburbs. The sort of houses that took just a touch of an architectural idea, but were never  brave enough to do anything with it. Some have a rounded porch. Others bay windows or a spot of half-timbering – but it’s always done so inoffensively that it has quite the opposite effect to the modern eye. There’s nothing wrong with these houses – I’ve lived in one. They’re comfortable and practical. But boring.

Now the house Muybridge died in is number 2, yet these houses had bigger numbers that grew rather than reducing as I walked along the road. And then it becomes obvious why. Suddenly I was in the real Liverpool Road with bigger houses, older, nothing fancy but much more effective. And there was number 2. Perhaps there was nothing else in Muybridge’s day – this was where the road started and the rest was what? A park? (Is it a coincidence that number 2 is called Park House?) No matter, I was there, the blister was worth it.

 Now I have to confess I was very nervous at this point. It’s one thing to go into a shop or even knock on the door of a business and ask if you can take a look, but it’s another to walk up to the front door of a private house and ask them, as I hoped to, if there’s anything left of Muybridge’s time there. Do they ever, when digging the garden, I wonder, come across the remnants of his scale model of the American great lakes, the garden feature he was working on when he died?

A deep breath and I approached. The house was almost hidden behind a wall and mature trees with a gate at each entrance – high, solid metal, green painted gates that you can’t peek through. High, solid, metal, green, locked gates. No way in. Okay, I thought, I’ll try the entryphone, ask for an audience. There wasn’t one. Even a prison has an entryphone, but 2, Liverpool Road was a blank, faceless, impenetrable mystery. I took some photographs, of the building and the couple of commemorative plaques on the wall. I stood a little longer.  But there was nothing left to do. Nothing but trudge back to the centre of town and the railway station.

There is a postscript to this. I couldn’t believe that the occupants of 2 Liverpool Road could have no interest in the fact that their home once housed a famous person. I wrote them a very nice letter, with a stamped addressed envelope enclosed. Asking for a little colour. Anything they could tell me. There was no reply. Is there anyone in there, or just cinematographic ghosts?

What were magic books for?

I'm currently reading Philip Ball's new book Invisible for review (you can find out more about it at or and there is a very interesting, if slightly pointed remark about magic books in it. Ball says:
'Magical books thus acquired the same talismanic function as a great deal of the academic literature today: to be read, learned, cited, but never used.'
I did rather enjoy the dig at poor old academics, though there is an element of truth to make that dig stick. But I was also interested in the idea that these kind of books weren't really meant to be used.

I was familiar with some of the early versions, as Roger Bacon was fond of one of the many (now known to be fake) books over the years called something like 'Secret of Secrets', usually claiming to be the wisdom of some ancient seer - in Bacon's case of Hermes Tresmegistus, a fabled mystic who seemed to combine Ancient Greek and Ancient Egyptian wisdom in one soggy whole.

Ball's assertion is an interesting one, because I had always assumed that the impossible-to-follow complexities of books of magic spells were primarily so the faking author could always say 'It's not the spell's fault, but yours that it didn't work, because you didn't quite do it right.' (Interestingly a similar argument is sometimes applied to alternative remedies in the health sphere.)

Rather than this, Ball suggests that the obscurity and impracticality is like a badge, a recognition of mutual membership of a secret and powerful society. And I think that when you realise that, you look at scientific papers and esoterically complex maths being employed in science in a new light. Not to say it mustn't be used, in some Stalinist-style attempt to impose political agendas on scientific theories but rather as further explanation to scientists that this why popular science, flawed though you may believe it to be, is so important, because it allows us to lift the veil and show that scientists are not just the latest proponents of magic, but doing something far better.

The fragility of physics

We are used to thinking of science as being logical and ironclad in its approach. Admittedly, it doesn't provide the ultimate truth or definitive facts. One of the hardest things for many to grasp (including some scientists) is that all science can ever do is give us the best theories supported by the current data. It only takes one new observation that can be verified to throw the best scientific theory out of the window.

At least that is the principle. But scientists are human and certainly don't want to start from scratch when this happens. So what they usually do is patch. They modify the theory until it does fit the data again.

The trouble is, you can only do this so far before the creaking theory becomes hard to keep alive, but by now it is often a Frankenstein's monster with a life of its own, sustained apart from anything else, by careers that have been dedicated to bringing it into being.

This was always the complaint Fred Hoyle had about the way his steady state cosmology theory was so easily discarded. Evidence came out from very distant observations, far back in time, that aspects of the universe were not as his theory predicted. So it was thrown out (American cosmologists never liked it, so this was easily done). Hoyle and his colleagues subsequently patched it in the usual manner so it would match current observations, but it was ignored. Here's the thing, though. Along the way, the rival big bang theory (Hoyle's derogatory title) was also patched. At least three times. So when data came along to show that big bang was wrong, it wasn't thrown out. Politics in cosmology? Quite possibly. I'm not saying steady state is right - it most likely isn't - but the decision when to accept a patch is arbitrary and has an element of politics about it, something outsiders would not expect from science.

However, the patch I was thinking of in my title 'the fragility of physics' wasn't in the field of cosmology which, let's face it, is always likely to contain an element of speculation.  What's more, this is a patch of jaw-dropping, ear-wiggling proportions. It was so extreme that Paul Dirac, one of the greatest physicists who ever lived, refused to accept the theories depending on it. And that's a problem.

A great book... but
spot the patch
Why? Because these are some of the most central (and wonderful) theories in physics. Quantum electrodynamics, for example, which explains the the interaction between light and matter (and the electromagnetic interaction between matter particles). QED is generally held up as one of the greatest theories in physics. It is astoundingly accurate in its predictions - as Richard Feynman was fond of pointing out, it makes predictions that match experiment with an accuracy that is the equivalent of predicting the distance from London to New York (he used two US cities, but let's not be parochial) to the width of a human hair. And QED depends entirely on this patch. As does the standard model, our current best model of how matter and three of the four forces of nature work and interact.

The name given to this patch makes it sound harmless - it's called renormalisation. So why did it get Dirac in such a twist? Because theories like QED are quantum theories that rely on adding together all possible outcomes with their associated probabilities. And because quantum theory allows interesting things to happen like pairs of matter and antimatter particles to pop out of nowhere and disappear again all the time, it has a tendency to predict that some essential values are infinite. So, for instance, without renormalisation, QED told its mystified developers that the mass of an electron was infinite.

This clashes a teeny bit with reality. We know the mass of an electron. It's around 9x10-31 kg. That's small. It's 9 divided by a very big number, 1 followed by 31 zeroes. Rather different from infinity. (To be fair, any number is as different from infinity as it gets.)

So what did Feynman and crew do to patch it? They knew the mass of an electron, so they ignored what the theory predicted and plugged the actual value in. And the result of this 'renormalisation' was that QED worked wonderfully.

We should never forget, though, that Dirac had a point. This is a very scary thing to do - and QED and the standard model and all the work that is built on that edifice has this patch as its absolute foundation. Renormalisation can be justified for the same reason that Newton got away with using his early version of calculus, which also had a flaw involving infinity at its heart. Because it works.

But it doesn't meant that there isn't something missing from the theory, something that might send physics in a whole new direction, overthrowing everything we've done in this field to date. And that's why I love science dearly. Because if that does happen, while some will grumble, and some will never let go of their favourite old theory, science as a whole will move on, and most will be thrilled by this new development.

Proper summer reading

The actual beach I intend to be sitting on with these books
I recently mocked a feature in the Observer, where lots of the sort of people who always get asked this kind of thing, told the paper all the boring, worthy and generally show-offy books that (they claimed) made up their holiday reading.

The piece is labelled 'best holiday reads' - but these books really aren't holiday reads at all. We all know that these select literati will leave those classics and economics tomes at home and pack the Dan Browns (or, for the more tasteful, P. G. Wodehouse) in a plain brown wrapper. Or, even better on a Kindle. So I thought it was time to come up with an honest holiday reading list.

Here are three books I've just bought to take with my to sunny France later in the summer:
  • Neal Stephenson: Reamde - because every holiday pile should include one book that's thick enough to act as a doorstop and/or to defend yourself against muggers and bag snatchers. And Stephenson is certainly good value for money - but also manages to entertain, and get the brain going at the same time.
  • Dave Gorman - America Unchained - because I love a humorous travel book as light reading. While I'm not sure anyone can equal Bill Bryson, I'm sure Mr Gorman will prove highly entertaining on his trip around the US.
  • James Runcie - The Perils of the Night - what could be more relaxing than a good British murder? And in this case it's set in Cambridge, so a double bonus. I've no idea if the books in this series are any good, I just picked it up off Waterstones' 'BOGOHP' table, but every holiday read should include one shot in the dark.
... what, you may, say, no popular science books? Well, no - I read about 40 popular science books a year, so for me it's time for a break. But that doesn't mean that they don't make great holiday reads for less regular popsci readers - so I'd be delighted if you called in at to select some holiday fun (or even to rip me off as my Quantum Age is still 99p on Kindle) - but equally, should you want to confess to Mills and Boon or Agatha Christie, feel free. It's a holiday, after all!

So... what are yours? Honestly, now.

Masters of Grauniad Central

The panel looking gormless
(photo Debbie Gilpin @Deborah_Deborah)
I had the pleasure of helping organise and taking part in a 'How to write a popular science book' masterclass on Sunday, and just wanted to take the opportunity to say that if the attendees enjoyed it as much as I did they will have had a good day indeed.

We had a fascinating keynote speech on why communicating science is important from Professor Stephen Curry, one of the organisers of Science is Vital and an early scientist blogger, a great talk from science journalist and author of Geek Nation Angela Saini on what makes a good popular science book (and what doesn't), various odds and sods from me, ranging from research to selling your book, and a spot-on fact-filled guide to producing the perfect proposal and the book production process from ex-MD of Icon Books and author of The Science Magpie, Simon Flynn.

The closing part of the event was a chance for members of the audience to give brief pitches for book ideas to panel made up of Simon, bestselling author M. G. Harris and me so that we could (hopefully) give some words of wisdom.

Throw in the most lavish 'light lunch' I've ever had and it was a day that went past remarkably quickly. Apart from seeing old friends in the other presenters, I really enjoyed meeting the audience, who were a fascinating bunch, and hearing some of their book ideas, at least three of which I would be rushing out to buy if they are ever published.

Lessons? Many. But I would particularly note the importance of having passion in your subject and narrative in your writing - plus having an utterly brilliant proposal. 

It was a great day and I hope we have a chance to do another.

Please rip me off!

Here's the thing - I'm very pleased with my new book The Quantum Age. It combines the weird and wonderful nature of quantum physics with an exploration of remarkable quantum applications, from lasers to superconductors, and the stories of the development of these ideas and technologies featuring some big (and sometimes decidedly strange) characters.

The Kindle edition usually sells for about £8.99, but as part of their 'Summer Reads' promotion, Amazon currently has it at 99p ($1.69) - because why wouldn't you want to read about something as mind boggling as quantum physics on the beach? Being a Kindle ebook, you can read it on a Kindle device, but also on tablets, smartphones, laptops, the better kinds of abacus* - so there's no excuse.

You are probably thinking, yes, but I don't want to deprive Brian of income. Don't worry - I really do want you to get a copy. Leaving aside the fact that not everyone would buy it at full price, if enough of you do buy it at 99p it can soar up the Kindle charts, become much more visible and that gives it a huge amount of momentum of its own.

So please do rush over to (just click that link) or, and rip me off. You'll make my day. (And please spread this as widely as you can!)

*OK, maybe not the abacus.

To boldly stay at home

I was mildly depressed by the title of a piece in The Telegraph the other day by Sinclair Mckay. 'Let's hope galactic travel never takes off,' it reads, with the subhead 'A British launch pad for space tourism will diminish the mystery of the universe.'

One of the reasons I was mildly depressed was that in a few weeks time I've a new book out from my US publisher, St Martin's Press called Final Frontier, celebrating our attempts to travel into space and looking positively into the future.

To be honest, the article isn't as extreme as the title, but I think there are several ways that Mr Mckay gets it wrong. The first is that term 'galactic travel'. Of course any space travel is likely to be 'galactic travel' in the sense that it's unlikely to be intergalactic - but by that argument, nipping down to the shops is galactic travel, and that already has taken off. Quite a while ago. I think the headline writer is investing too much in Richard Branson's rather cocky (oxymoron) 'Virgin Galactic', as the kind of travel that's likely to happen from a British spaceport would mostly be sub-orbital - so not really even travel within the solar system, let alone on a galactic scale.

As for that subtitle, there is no more baloney than to say space travel 'diminishes the mystery of the universe'. This is reminiscent of the Keats suggestion that Newton somehow diminished the wonder of nature by explaining the colours of the rainbow and unravelling its mysteries. As Richard Dawkins so eloquently pointed out in his book Unweaving the Rainbow (see, I can say nice things about him), the reverse is true. When we find out more about the rainbow (or the universe) we add extra depths of wonder - we still have the joy of seeing it, but we also have the thrill of understanding it. Mystery is a great tempter, but we also want some outcomes - if all mysteries remain unfulfilled it is not enough for any but the gullible - and the wonder of the universe is that there always new mysteries, so we don't run out of challenges.

As it happens, the text of the article has some elements I can agree with. Simply popping into space to see the view - space tourism - is not really advancing humanity and, frankly, would be nice if we could do without it, were it not that it is a good way of funding some aspects of space technology, because one of the big shifts in the way we approach space travel is the increasing involvement of the private sector. This is too big a venture to leave to either governments or the private sphere alone.

I'm not, by the way, arguing that instead space exploration should be mostly about science. It is never going to be mostly about science. We can pretty well always get more bangs for our scientific buck by using unmanned equipment than going to all the expense of keeping humans alive. But one thing I did rediscover when writing that book was my sense of joy in the idea of humans going out into deep space. Yes, it is corny - but there really is something special about boldly going in good Star Trek fashion.

So when Mr Mckay says 'I mean no disrespect to the platoons of boffins... It is more to do with a sense that the illimitable darkness and mystery of the universe has already been diminished.' I say tosh and baloney. The more we find out about the universe, the greater its sense of wonder. The medieval universe was little more than the solar system - they had no idea about the kind of amazing sights that the Hubble telescope (only made possible by going into space) gives us every day.

Bring it on.

Doing pretty well?

Yesterday, a couple of people on Facebook shared this Voltaire quote with me, illustrated by an image of the masses being crushed by a rich hand. (You could tell it was rich, because it had a fancy bejewelled ring.) It struck me this was a much more interesting concept than was probably intended, because it may well tell us a lot about how things have get better, at least in some parts of the world.

The fact is, in the West at least, we are doing pretty well on this measure, to the extent that you begin to wonder if anyone does rule over us by this definition (is that democracy?).

Specifically there is no possibility that we aren't allowed to criticize politicians or bankers or rich businesspeople (if you doubt this, watch an episode of Have I Got News for You). We don't just do it, we do it for entertainment. We are also allowed to criticize religion as we never were before, which is just as well when you look at the amount of negative stories in the news with a religious context. (A lot of people are scared of criticizing one particular religion because of fear of irrational backlash, but that is very different from not being allowed to criticize.)

There was a time when we weren't allowed to criticize the establishment - but that goes back to before the 1950s, and as the recent kerfuffle over the Butler-Schloss appointment shows, there are now no forbidden targets there.

So who aren't we allowed to criticize? Perhaps anyone the media considers to be a 'saint', though even there, thanks to Jimmy Savile, we are beginning to realize that media sainthood isn't all it's cracked up to be. I could joke about people from Liverpool, or Welsh rugby players and male voice choirs - but that's just as case of people not liking their pride being dented, not a situation where we aren't allowed to make a criticism.

You might say that the draconian libel laws mean we aren't allowed to criticize anyone with lots of money, but even that's not really true. We are allowed to do so, but we need to make sure our allegations are backed up by evidence. And surely that's not a bad thing? Of course there will be specific cases like Simon Singh's appalling treatment by the BCA where a bad decision means unnecessary suffering, but that has led to a change in the law - and he did win in the end.

So, just for once, perhaps we should give ourselves a pat on the back and stop being so negative. Well done, us.

Hearing infinity

I frequently get emails from people who have read my books (usually satisfied customers!) - but the other day, for the first time, I was contacted by someone who had enjoyed listening to one - the audio book version of A Brief History of Infinity.

Something that was particularly encouraging about hearing from Richard Madigan in New York was that the audio experience was sufficiently clear that he felt inspired to produce the graphic below of Galileo's 'parallel wheels' thought experiment.

For some reason I had always imagined it turning the other way, but it's fun having a concept in an audio book made very elegantly visual this way.

Here's the GIF:

Soil Association versus science

The Soil Association's carefully worded announcement heading
I like to keep an eye on the UK's organic body, the Soil Association. I have been a little suspicious about their approach to science ever since I queried an outburst from them on the subject of nanoparticles six years ago.

In January 2008, the Soil Association, banned nanoparticles from organic products. Nanoparticles are ultra-small particles of anything, provided the substance is divided up into pieces that are just a few nanometres (billionths of a metre) across. But the Social Association specifically only banned man-made nanoparticles, claiming that natural ones (like soot) are fine because ‘life has evolved with these.’

This is just not an acceptable argument. If a nanoparticle is dangerous because of its scale – entirely possible, because the physics (rather than chemistry) of particles of this size is quite different from the objects we are familiar with – then that danger is just as present whether it’s natural or not. Even where scale isn’t the only factor, natural nanparticles can be dangerous because of the way they interact with the body.. Viruses are natural nanoparticles, and like soot, aren’t ideal for the health.

The Soil Association defends its position by saying that their approach is on a parallel with carbon dioxide in the air, where there is no problem with the natural carbon dioxide, only the manmade extra contribution. This is a specious argument, both because carbon dioxide is carbon dioxide, and if levels are too high it doesn’t matter where it’s coming from – but also because there is no comparison between CO2 and a nanoparticle that could be directly physically dangerous to humans.

To make matters worse, the Soil Association also say that it can’t control natural nanoparticles present in the environment, they’re just there. But this is relevant; the Soil Association isn’t an environmental control group. It is discussing what goes into organic products, and there is nothing to stop a manufacturer putting natural nanoparticles into a product either by accident or intent. You might as well say we don’t mind a manufacturer putting salmonella into organic food, because it’s natural. If the Soil Association believes nanoparticles are a bad thing, it should ban all nanoparticles from a product that gets their seal of approval, not just artificial ones.

In summing up, the Soil Association let slip the reason it takes this strange attitude. I was told by a representative ‘[T]he organic movement nearly always takes a principles-based regulatory approach, rather than a case-by-case approach based on scientific information.’ In other words, theirs is a knee-jerk reaction to concepts, rather than one based on actual science.

The latest example of this in action was a joyous announcement they sent out proclaiming that a 'landmark paper' had shown significant differences in the nutritional cogent of organic and non-organic crops. (Interestingly, they did not send out a similar email when the last two papers came out showing no significant differences.)

Even though the Soil Assocation email gives the appearance of celebrating a victory for organic food, it is very carefully never actually says that the study showed that organic food was nutritionally better - and there's a good reason for that it. It doesn't. The big item that the Soil Association flags up is that the study showed more antioxidants in organic food. Unfortunately, this is a dead duck argument. There is no known nutritional benefits from consuming antioxidants. The only known outcome is that if you consume too much (typically from supplements) it increases the risk of death. So quite why they were trumpeting this as if it's a good thing, I don't know.

The email goes on to mention a couple of other lesser items, including the old canard about pesticide residues. But what it fails to mention is that the only significant nutritional difference highlighted by the study was a negative for organics. It said that organic food had a small but significant deficit in protein compared with non-organic food. As Professor Tom Sanders of King's College, London commented to the BBC: 'In terms of macronutrients (protein, carbohydrate, fat), the organic products contained less protein. Other nutrient differences were trivial and well inside the normal range of variation that occurs with different varieties, soil types and variations in weather.'

Strange they didn't mention that.

It's not natural

Human hair louse - nature at its best
There used to be a common saying - less so in these 'everything goes' days - where people would shake their heads and say 'It's not natural.' But they got it all wrong - what they were really thinking is  'it's not civilised' or to put it another way, 'it's too natural.'

The reason this phrase is so back to front is that we have a rosily incorrect mental picture of what is 'natural'. As soon as we hear the word we get a knee-jerk reaction that's all rosy and fuzzy about rolling hills and beautiful scenery and pretty animals and whole grain, organic, hand-knitted yoghurt. And of course there are circumstances where natural is better. Processed foods for instance. There are nations that are particularly good at beating the nature out of food and drink - dare I mention US squirty cheese (or is it Cheez?), chocolate and attempts to make tea to name but three.

However, most of the time, being natural is not so good. Here's a few aspects where we've improved on being natural.

It's natural:
  • ... to die young. Without modern medicine the majority of people die before reaching adulthood.
  • ... to encounter poisons and pesticides. Some of the most poisonous substances in existence are natural, many of them acting as natural pesticides.
  • ... to suffer in the sun if you have fair skin. Okay, evolution can naturally take care of this to some extent by increasing pigmentation (or by not losing it in the first place), but this takes time and doesn't help you personally.
  • ... to be afflicted by parasites. Worms, fleas, lice - that's everyday reality. No one said nature was nice. But you can have fun grooming each other.
  • ... to stay in a relatively small area for life. Like visiting far flung places? It's unnatural.
  • ... for life to be unfair. We apply lots of unnatural 'fairness' to help those who need it, whether it's benefits or aid for those with disability and chronic illnesses.
I could carry on for a long time. I hope you get the point. There was no bucolic, happy, natural past to wish we could return to. Not everything modern or unnatural is good - we need to keep and cherish the best of nature - but things are mostly far better than nature provides, and we should be thankful for that.

Red hair twaddle

Yes, alright, it was a windy day.
I feel the strong urge to share with you what may be the worst piece of science-based reporting I've seen this year. It's from UK free newspaper Metro and it is titled Red head? Climate change could make you and your ginger compatriots EXTINCT. (The usually respectable Independent also covered this 'story.')

It may not be obvious now, but as the slightly younger picture of me alongside demonstrates, I am a member of this apparently endangered grouping. But what does the story say exactly? I will extract some of it's joyfulness, so you don't have to read it (though admittedly in the original you get a picture of Lily Cole rather than me).

The suggestion is that due to climate change and the 'rapidly increasing temperature across the British Isles, the red hair gene could soon be a thing of the past.' And the way we are told this story makes me shudder - and not because I am an endangered ginger. Take this line:

Scientists believe that we evolved over time to have red hair in this part of the world because of a lack of sunshine.

Whoa! Now first of all, the *HMMM* detector is always alerted by being told that 'scientists say' or 'scientists believe'. Who are these scientists and where can we find their paper on this subject? I don't expect a newspaper article to give me an explicit reference (though it would be nice), but I would like to see 'Dr Hamish McSpod of the University of Life made it clear in his paper "Why gingers are doomed" published in Nature'... or whatever, so I can nip over and take a look. What do we get? Nothing. I have asked Metro for references, but strangely they haven't replied.

And second of all, we didn't evolve to have red hair 'because of a lack of sunshine.' I could accept that an accidental mutation producing red hair and pale skin resulted in preferential survival in a low sunshine location like the UK (as the pale skin makes vitamin D production easier with less sun exposure), but don't make it sound as if evolution thought 'ooh, lack of sunshine, let's try red hair'. It doesn't work that way.

We then get told by Alastair Moffat of 'Scotlands DNA' that ‘If it was to get less cloudy and there was more sun, there would be fewer people carrying the gene.’ Hang on. Alastair Moffat of what? ScotlandsDNA is a company that 'aims to provide new insights into the genetic origins of Scots and those of Scots descent'. It does this by selling DNA tests. For money. And Alastair Moffat is a former director of the Edinburgh Festival Fringe, so clearly knows what he is talking about when it comes to science.

But leaving aside the suspicion that this was an article driven by a press release to sell DNA tests, is what Mr Moffat said true? If there were more sun, he tells us, there would be fewer people carrying the gene. This would be true if lots of red-haired people were dying out before they could reproduce (presumably from skin cancer). But we have this high tech stuff called sunblock now, and us red-heads really know how to use it. What certainly isn't the case is that evolution will some how decide 'We don't need that gene any more, as it's sunny, let's get rid of it.' Evolution is not directed.

Then, after the obligatory picture of Prince Harry (no comment), comes the absolute cracker of a finale:

Those with the warm-toned barnet can, surprisingly, create their own vitamin D, to make up for the fact that they cannot get it from sunshine as easily as people all over the rest of the world can.

So yup, you do the math. More sunshine equals more vitamin D, which means, our hair doesn’t need to do the work for us.

Please read that at least twice, because it is wonderfully bizarre. Bear in mind that:

  1. Everyone makes their own vitamin D from sunlight hitting their skin - it's just that fair skin lets more ultraviolet through, making vitamin D faster than does a darker skin. 
  2. Our hair does not do any work for us. It is dead. If you believed this article, you'd think there was a vitamin D factory in your hair, pumping the stuff into your body.

Listening to Time Machines

 One of my favourite activities is giving talks based on my books, and I'm grateful to Bath University for hosting a talk recently on How to Build a Time Machine as part of their General University Lecture Programme.

While an audio version misses out on the excitement of seeing me wave my arms about (not to mention missing the sight of the cardboard box of time), it still might be of interest to hear the talk, which doesn't use slides. You should be able to play it using the controls at the top of the screen - but if that doesn't work, click here to access the podcast. It lasts about 45 minutes.

If it's a subject that interests you, please take a moment to have a look at my book, which inevitably can go into a lot more detail and cover many more aspects of the science of time travel.

What is it?

A little quiz for you today. What do you think this is?

A few helpful hints. 'A piece of tree' won't do - this is a part of a piece of early technology. But what was it used for? And how? To give some scale, it's about 30 cm across.

And the answer is...

... it's a piece of a wooden water main. I saw it on a visit to WRC in Swindon with Radio Wiltshire presenter Mark O'Donnell (the recordings of our visit will be broadcasting on his Sunday morning show, probably starting next Sunday). The company provides services to the water companies and have interesting facilities, including an indoor section of road as a test pit where pipes are buried and then put under pressure to see how and when they fail.

Remarkably, the WRC chief exec informed us that, in all probability, there are still some wooden water pipes in use in the UK. Another surprise was to discover that a fair number of older houses still get their drinking water through lead pipes. The water companies use a dilute phosphoric acid to coat the pipes on the inside so that lead doesn't get into the drinking water.

Half getting Spotify

Some related artists, earlier
I can't justify paying £10 a month for Spotify, the music streaming service, but I have dabbled with the free version, and now that it is possible, for instance, to specify that you want to play the tracks of a specific album in the mobile version (even if it has to be shuffled), I am finally starting to get the point of Spotify. Of course, it's useless for all my 70s concept prog rock albums, which have to be played in the correct track order, or Rick Wakeman comes round and duffs you up. But for a lot of others, shuffle is just fine.

However I do still have a bit of a problem with the streaming service (over and above the feeble royalty payments they make to the performers). The thing is, when I want music at the moment I typically go to my iTunes library and flick through it and I'm looking at stuff I know and love - I can browse it sensibly. But Spotify is too big to browse in an undirected fashion.

I find myself staring at the interface thinking 'I can play almost anything. What should I choose?' And I don't know where to start. If you go into Browse, it really doesn't help. I know I can, for instance, go into Pink Floyd and choose 'Related Artists'... and use that kind of mechanism to navigate through stuff I might like... but even so, it's hard work.

So much though I find the concept appealing, I think I'm still mostly stuck in old fogy iTunes land.

Get started on your book!

I'd like to draw your attention to the 'Writing a popular science book' Masterclass organised by the Guardian on 20 July in London.

Whether you are a scientist who would like to get wider public interest in your field, or just someone who has always wanted to write a book, this is a great opportunity to gain the necessary know-how on everything from choosing topics to selling your idea and the publishing process.

With talks from scientist and communicator Professor Stephen Curry, TV presenter and author Angela Saini, former science book publisher and author Simon Flynn, award winning science writer Brian Clegg and former biologist and author M G Harris, plus the opportunity to pitch your book ideas to an expert panel for instant feedback, it should be a brilliant day. 

To ensure a place, tickets need to be booked by 7 July - you can find all the details on the Guardian website.

Here's a little more about the team:

Brian Clegg is a popular science writer with 20 books in print who has written for publications from the Observer to Playboy. After degrees in Natural Sciences and Operational Research, he worked at British Airways before leaving to set up a company giving training in business creativity. These days, most of his time is taken up writing popular science books and giving talks. He is a Fellow of the Royal Society of Arts. Find out more on Brian's website.

Angela Saini is a British science journalist and author, whose first book Geek Nation: How Indian Science is Taking Over the World was published in 2011. Angela has also been published in Science, Wired, the Guardian and New Scientist and is a frequent presenter on BBC radio, for shows including Material World and More or Less. In 2008, she carried out an investigation into bogus universities which was broadcast on the BBC TV's flagship Ten O'Clock News.

Simon Flynn has degrees in chemistry and philosophy and worked for a good number of years in publishing, becoming managing director of leading UK independent publisher Icon Books. He recently left the publishing world to become a science teacher.

MG Harris is the author of the popular Joshua Files series of novels. Born in Mexico and brought up in Manchester, she studied biochemistry at St Catherine's College, Oxford University, before pursuing a doctorate at St Cross College, Oxford. MG spent several years working in research laboratories before setting up her own internet company. She is a successful young adult fiction author and will bring to the panel a mix of expertise in biology and in the narrative style so important for good popular science. In an attempt to cover up the fact that at heart she's a bit of a geek, MG spends as much time as possible going out to salsa clubs to dance.

Stephen Curry is a Professor of Structural Biology at Imperial College. His main research interests are in structural analysis — using X-ray crystallography— of the molecular basis of replication RNA viruses such as foot-and-mouth disease virus and noroviruses (which include the infamous 'winter vomiting bug'). Since 2008 Curry has written regularly about his research and the scientific life past and present on his Reciprocal Space blog and at the Guardian, Curry is also a founder member and vice-chair of Science is Vital, a UK group that campaigns on scientific issues, and is on the board of directors of the Campaign for Science and Engineering.

Now that's what I call a graph

Reading for review Superintelligence by Nick Bostrom, I couldn't help but be struck by this graph:

The remarkable thing is, if you zoom in, a huge amount of that growth has happened in my lifetime. We talk casually of change, but I think this emphasises how different things are now from the way they have been at any time in history.

And as for the famous climate change 'hockey stick' graph - 'Call that a hockey stick? THIS is a hockey stick!' (HT to Crocodile Dundee.)
