Last night, my new two-part documentary, Light and Dark, aired on BBC4. The man who deserves almost all the praise is director/producer, Stephen Cooter. He wrote most of the script and put the 120 minutes together into something special. It was produced in partnership with The Open University, and essentially explores how we have uncovered the secrets of our universe by using and manipulating light. It is therefore another one of those science docs I enjoy making that mix stories from the history of science with mind-blowing big ideas and concepts that BBC4 audiences enjoy. You can watch it on BBC iPlayer here.
The central premise of this series is that what the human eye can see is only a fraction of the vast amount of matter and energy that exists out in the Universe: our best estimate is that more than 99% of all the stuff that’s out there is hidden in the dark. So how do we know it’s there?
What the commissioners, execs and controllers at the BBC have come to appreciate over the past few years is that science programmes can be delivered across different platforms and at different levels to different audiences. And the stuff I enjoy doing is at a level isn’t aimed at the lowest common denominator. My audiences tell me they don’t mind if they don’t follow all the concepts, they want to be made to feel clever while watching and to have their minds expanded to the point of exploding – in a good way. I was recently told that certain top-level execs at the BBC referred to Light and Dark as ‘mindfuck TV’. I take that as a compliment.
So last night, both during and after the programme, I received a constant stream of comments on Twitter from viewers – so many in fact that I simply could not respond to all. To be fair, most were lovely short tweets saying how much they were enjoying the programme. I have selected a few below that I thought it would be nice to share. Obviously I have removed the Tweeters’ names.
Firstly, let me say something about the cinematographic technique we used to give that wonderful lighting effect. It was achieved using what is called a ‘day for night’ filter on the camera (BTW, cameraman Tom Hayward is quite excellent). The method is also known as nuit américaine (“American night”) and is used to simulate a night scene while filming in daylight. The point being that we wanted to mix up day and night and play with the concept of light and dark. Historically, infrared movie film was used to achieve an equivalent look even with black-and-white film. So it is not new. But it does give a different feel to the films and the vast majority of viewers (going by the statistically reasonable twitter comments) thought it worked brilliantly:
“Light is the key subject of painting, ‘Light & Dark’ is certainly the best program on #art I’ve seen for a long time!”
“the cinematography is beautiful. Unique, relevant and original approach.”
But to balance this, of the very many in favour, there were a tiny number who didn’t like it:
“I think it’s spoiling the programme – to the extent that my wife and I have more or less stopped watching it.”
Well, you can’t please everyone. And at least I didn’t get what Brian Cox seems to have to put up with: complaints that the background music is too distracting.
I was also pleased that a number of viewers picked up the bits where we had some fun, such as the lift sequence going up the medieval bell tower in Venice:
“Loved Light & Dark, especially the ‘Girl from Ipanema’ nod to the Blues Brothers”
Obviously, I appreciate that although I see myself as an incredibly handsome young man, I might not appeal (in a boffiny, eye candy sort of way) to all the young ladies out there, but do I take the following as a compliment?
“My 86 year old mum enjoyed it too. She says you are very handsome. I at least agree with her taste in programmes……”
And these sort of comments don’t bother me at all, honest:
“Another great show, you are just as good as that Cox fella! ….. If only you had some hair!!!”
And as for BBC4 rather than BBC2:
“Superb TV, shouldn’t be hidden away on BBC4. How’d the ratings battle with #imacelebrity go?”
Well, I sort of assume that the overlap of audiences is rather small. And, yes it would be nice if these programmes aired on BBC2 as well. Of course, there are no DVDs to be made of the series as far as I know. So if people don’t record it or catch it on iPlayer, please don’t email or tweet me asking me how you can get hold of it.
Finally, a lot of comments on my use of a blackboard to write down algebraic equations, not just for aesthetic reasons (in a ‘look how beautiful this maths is and how clever I am for being able to understand it’ sort of way) but for a valid reason that is part of the story. In this case it was James Clark Maxwell’s derivation of what is called the ‘wave equation’ that has imbedded in it a very special number: the speed of light (300,000,000 metres per second) starting from a very technical set of squiggles and symbols better known as Maxwell’s equations of electromagnetism. Now, every physics student will learn about this stuff, but you do need to have studied advanced calculus to even begin to understand what the symbols mean, let alone follow my fast and tightly edited blackboard work.
But this is what I mean when I say the BBC have changed the way science is presented. Ten years ago it was unheard of (apart from on an Open University lecture programme) for a physics professor to write equations on a blackboard on prime time TV. I believe I am right in thinking that I started the ball rolling on my 2007 documentary, Atom. It is part of the same trend I mentioned earlier whereby audiences want to be involved in the excitement of someone appreciating high level maths used to uncover profound ideas about the Universe without necessarily needing to follow all the steps.
I should say that Brian Cox, in his Science of Doctor Who lecture at the Royal Institution that was aired on BBC2 last week, also wrote down Maxwell’s equations and derived the speed of light, just as I did. And that was on BBC2!!!!
Here are some comments about this:
“Fantastic show. Well produced, lovely cutaways complete and informative as usual. Well done! Wave equation simply stunning”
“Masterfully done, sir. (plus Maxwell’s equations on prime-time telly!) #LightAndDark”
“Yay! Shame they cut some of the algebra, but good to see this paid for by my license fee. Great show.”
“Great to see a grown up scientific programme which shows us the mathematics.”
OK, I acknowledge that many viewers would even have understood the maths. After all, I made sure all my own students were watching it.
And then there were those felt there wasn’t enough science. Yes, I know, you can’t please everyone. They asked: where was discussion of light as photons? Where was Einstein’s relativity? Where was Herschel’s discovery of infrared radiation? etc etc.
Come on guys, I only had an hour!
Anyway, I was left with a warm feeling after many tweets like these:
“Thanks for the best science TV I’ve ever seen. Brilliant! Reflections from your gleaming cranium in nearly every frame! ”
“Beautiful, in places almost poetic, stuff tonight. Can’t wait for part two”
Yes, part 2 is even more ‘mindfuck TV’. I will be delving into the mysteries of the Dark and reveal just how little we still know about our universe. I explain the strange discovery of dark matter and dark energy, a mysterious force that is thought to make up 73% of our universe, and is pushing it apart at an ever-more rapid rate.
Enjoy. Continue reading
This blog was prompted by an online article I was alerted to by Roger Highfield on Twitter, which discussed how neuroscientists were conducting experiments suggesting that free will is indeed just an illusion. It was rather dismissive of the years (no, make that centuries) of philosophical debate that has seemingly not brought us any closer to an answer. Now, as a physicist I am usually at the front of the hard-nosed scientist queue when it comes to philosophy bashing. But on this issue, I am not so sure. Continue reading
So, how do I feel about the Higgs discovery? Am I excited, indifferent or even just a little disappointed? Before CERN’s announcement on the 4 July 2012, I had asked myself on many occasions whether I hoped the Higgs would be discovered or not. After all, if there were no such thing as the Higgs field, or Higgs mechanisms that supposedly gave particles their mass, and hence no Higgs Boson (the particle that is no more than a brief condensation of Higgs field energy) then we would need to revise our theories of the subatomic world… and that would be pretty exciting. Well, it seems like that won’t be necessary (for now) because experiments have confirmed what theory predicted all along. Continue reading
I have been prompted to write this blog, instead of chilling with a glass of wine after a busy week and watching a movie on TV, because of the flurry of comments via email and Twitter that I have received today regarding the latest news from the Opera neutrino experiment.
It’s entirely my own fault. After the first announcement back in September I volunteered on Twitter, then on BBC television to eat my boxer shorts on live TV if this result is proven to be right. Now, many people mistakenly believe that this second repeated experiment is the confirmation needed for me to fetch the ketchup. Continue reading
I thought about tweeting this but realised I couldn’t explain it in 140 characters and I hate multiple run-on tweets. So here it is in a blog:
In October of this year I start presenting a new science programme on BBC Radio 4. It will be on every Tuesday at 0900 – a fantastic slot just after the Today Programme. In fact, the hope is that this will become a long-running fixture on R4 with around 30 or so episodes a year, so that the Tuesday 9am slot becomes associated with it. Just think what else is on at that time throughout the week: on Monday it’s Start the Week, Wednesday it’s Midweek, Thursday is In Our Time and Friday it’s Desert Island Discs. Tuesday is the only day without a recognised fixture.
The new controller of Radio 4, Gwyneth Williams, has been absolutely key in getting this programme commissioned – well, she’s the boss, right? Anyway, what is so fantastic is that Gwyn is very keen to get more science on Radio 4 and for science to continue its rapid move into mainstream culture – for instance, The Infinite Monkey Cage, presented by Robin Ince and Brian Cox, recently won a Sony Award.
So, what will the programme be about and why do I need your help?
The first thing to say is that this will not be like In Our Time with Melvyn Bragg, nor will it be like Material World, the excellent science magazine programme presented by Quentin Cooper. We have already recorded two pilots for the new series, differing in format, so that the powers that be in the BBC can decide on the style, format and flavour of the programme. At the moment, a very rough way of explaining what it is about is that it is like Desert Island Discs, without the discs. Each week, I will be talking to a different prominent figure from the world of science (by which I mean ‘science’ in its broadest sense: natural science, maths, engineering, technology, medicine and social science). There wil be Nobel Prize winners, shakers and movers, advisers to governments, writers or just fascinating people who have made a contribution to our understanding of the Universe. So, whereas Kirsty Young might ask her guests on DID something like ‘tell me why you never got on with your father’, I might ask ‘tell me where you were when you first had that Eureka moment that led to your scientific breakthrough’, or some such thing.
So, here’s the thing: we still don’t have a title for the programme!
We have come up with ideas like ‘Latitude‘, ‘The Life Scientific’, ‘This Scientific Life‘, ‘Science Talk‘. I even suggested ‘Curious Minds‘ but it was pointed out to me that that is the strapline for the whole of Radio 4: “Radio for Curious Minds”. Although it would be kinda nice to have the programme title reflect so perfectly the ethos of the network.
So, ideas please: either below in comments or tweet them to me (@jimalkhalili) with the hashtag #radio4sciencetitle
I thank you.
P.S. Apparently I am not allowed to offer a prize if a title is used but I will certainly publicise who came up with it if you are happy for me to do so.
So, 2011 is already shaping up to be another busy and exciting year for yours truly. As I write, I am currently coming to the end of filming on Everything and Nothing, a beautiful 2 x 1 hour documentary about some of the deepest ideas in science. It can be encompassed by the following quote by Blaise Pascal : Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed. Continue reading
So, I’m sitting on a train back from Waterloo to Portsmouth on a Saturday morning having just been interviewed on Radio 4′s travelogue programme, Excess Baggage. I really should now be reading that PhD thesis in my bag that I am still only a quarter of the way through. I mean it’s not as though it isn’t on a riveting topic in theoretical physics (“Antisymmetrisation of few-body models for light nuclei”) – and if the author sees this blog before the Tuesday viva, rest assured I will have read and digested it before then and promise to ask only ‘nice’ questions during your examination.
Anyway, I will get back to reading the thesis shortly, but this may well be a slightly longer journey than usual due to the snow, so enough time to finish this blog. After all, I have not updated my website since October and feel a little guilty knowing how many millions of people around the planet hang on my every word. You see, that’s the problem; in my blogs I feel I should only be writing about deep and profound subjects from my corner of science, rather than the self-indulgent, self-promoting ‘wot I’ve got up to recently’ stream of consciousness that is the preserve of ‘proper’ celebrities as well as the delusional egos for whom Facbook Status Updates are just not enough.

It is one thing to introduce the world’s most famous scientist to a live audience; it’s even more exciting to do so at a venue like the Royal Albert Hall. Well, that’s exactly what I got to do last Wednesday evening. There is of course no doubting the pulling power and star appeal of Stephen Hawking, and I knew that the 5,500 sell-out crowd could have been three times as big had an even larger venue, the O2 Arena, been chosen instead – as it nearly was. Still I was pleased it was at the fabulous Albert Hall.
