This blog is a riff on digital humanities. A riff is a repeated phrase in music, used by analogy to describe a improvisation or commentary. In the 16th century, the word 'riff' meant a rift; Speed describes riffs in the earth shooting out flames. The poet Jeffrey Robinson points out that riff perhaps derives from riffle, to make rough.

Maybe we need to explore these other meanings of riff in thinking about digital humanities, and seek out rough and broken ground in the digital terrain.

Riffs on McCarty


A recent highlight for the Department of Digital Humanities at King’s College London was the award of the Roberto Busa prize, the major international award for lifetime achievement in the digital humanities, to Willard McCarty, one of the founding fathers of the Department. Matthew Jockers in introducing Willard’s Busa lecture memorably described him as the ‘Obi-Wan Kenobi of digital humanities’, a denomination which Willard relished.

Occasional lectures of this kind can often be damp squibs, but Willard’s Busa lecture was truly memorable, because it mapped out an intellectual manifesto for the future of the digital humanities which is ambitious, exciting and inspiring. The title illustrates the ambition of the lecture: 'Getting There from Here: Remembering the Future of the Digital Humanities'. Willard’s lecture was live-streamed, and I understand that the archive video will shortly be available online. We are arranging for Willard to repeat his lecture at King’s in the autumn, and it will be published.

Willard’s lecture was incredibly rich and intellectually challenging, so it might be worth starting the process of unpacking his message. Willard’s lecture will I am sure lead to as much discussion and debate as his 2005 book on Humanities Computing, and the lecture should be seen as the next move forward from what Willard describes as the ‘intellectually claustrophobic territory’ represented by his book. Among the key themes in Willard’s lecture to which I would draw particular attention are:

- ‘Failure is our most important product’. In describing his work to see how far tagging could capture aspects of Ovid’s ‘Metamorphoses’, Willard urges us to move away from our preoccupation with creating user-friendly online resources which will enable humanities scholars with low levels of computer literacy more easily to search and interrogate their primary materials. Willard urges a more experimental digital humanities which explores the limits and inadequacies of computing. I couldn’t agree more. For too long, we have seen ourselves as evangelists of technology, trying to convince humanities scholars that machines can be helpful. The risk now is that, as digital technologies become commonplace in the academy, we will assume that there is only one way of doing things, a series of methods and standards which have to be shared and disseminated. The result will be an evisceration of the possibilities of the digital humanities. The only way to avoid this is to embrace that sense of computing as an ‘ongoing, never ending experimental process’ described by Willard, but that means radically changing the type of things we assume that digital humanities should do – death to projects; more experiments, more tinkering, more just trying out.

- ‘Imaginative exploration’.  Willard picks up on Busa’s 1976 question ‘Why can the computer do so little?’ to criticize our assumption that computers simply enable us to reduce the drudgery of scholarship by performing routine tasks more quickly. Thinking of the computer as a ‘mere’ tool is a way of making it safe – it becomes from this perspective just a humdrum piece of technology which gets rid of the tedious aspects of research. Such thinking is a way of avoiding confronting the radical epistemological and phenomenological implications of computing. If we think of digital humanities as a series of ‘methods’ which can be ‘applied’, we are complicit in such denial of the radical implications of the computer. Digital humanities is not a series of methods which can be learnt or introduced but rather a field of exploration. We need to focus on imaginatively exploring the potential (and limitations) of computing rather than on creating ever more efficient scholarly data crunching.

- Learning from artists. Referring back to the 1968 Cybernetic Serendipity exhibition at the Institute of Contemporary Arts, ‘at which artists and engineers experimented with ideas so far ahead of their time they remain mostly ahead of ours’, Willard urges those engaged in the digital humanities to create a stronger dialogue with technologically aware artists. This is a theme I have found echoed in my own work on the AHRC’s ‘Digital Transformations’ theme where it has become evident that the time is ripe for a stronger cross-over between the digital arts and the digital humanities. The kind of work with arduinos, conductive inks or mBed microcontrollers is precisely the field for that restless experimentation, the constant tinkering, that Willard urges us to engage in.

- ‘We need the technosciences just as much, more than many of us realize, more than some of us fear.’  Willard powerfully argues the need for the digital humanities to connect more closely with the sciences. At one level, this is simply because the discipline will wither and die if it loses its connection with its epistemological roots. At another, shared issues and concerns mean that scientists are people we can and should be talking to. One of the most fascinating events I attended recently was a multi-disciplinary workshop on theproblems of Big Data organized by the Large Hadron Collider community. The cross-connections and parallels across different disciplines were fascinating. We need more of that sort of dialogue – we won’t learn much new from talking to historians or classicists but talking to scientists will lead us into completely fresh pastures.

- Where is the criticism? Willard, taking up questions posed by Alan Liu and Fred Gibbs, emphasizes the importance of retaining a critical stance in exploring these areas. Indeed, one of the things which we as humanities scholars bring to the table in discussions with scientists and technologists are the remarkable theoretical tools which are among the great intellectual achievements of the past fifty years (and in turn have their roots in the scientific discoveries of men like Einstein, Heisenberg and Freud). The most fruitful areas of future development for the digital humanities will be at these intersections of science, art and criticism – as critical code studies are beginning to illustrate. A key element for this in Willard’s discussion is the importance of historicizing our understanding of an engagement with computing.

- Resonate with the humanities! Just as digital humanities wilts if it ignores its roots in computing science, likewise its roots in the humanities cannot be forgotten. Willard expresses the aim perfectly when he says that the results of our foraging across the sciences, technology, arts and culture should ‘resonate with the humanities’. The mix we produce from our hunter-gatherer expeditions will not necessarily fall into such easily recognizable categories as history, literature or archaeology, but what we find and express should have resonances across all these disciplines. Here, I think we can draw inspiration from disciplines such as bibliography or manuscript studies. To take an example from my own work, my study of the restoration of the burnt manuscripts of Sir Robert Cotton has, I believe, implications across a range of historical, literary and other studies, but I would find it difficult to categorise it as history or literature – I hope it has wider resonances, as our DH experiments should.      

Willard described in his Busa lecture a new type of digital humanities. This is a digital humanities which remembers its roots and traditions – indeed to some extent Busa’s 1976 question ‘Why can a computer do so little?’ provides the key epigram for the lecture. It is a digital humanities which is intellectually restless and exists in marginal lands: ‘I’ve imagined us as maritime explorers in an archipelago of disciplines, peripatetic, prowling the margins; I’ve imagined us with the novelist David Malouf, adventurous youth discovering life and death in a wild, dangerous acre of bush’. This area is defined by a triangulation between science, digital arts and making and cultural criticism. It is an area of experiment – of tinkering and playing with cross-connections. It is a zone of failure but also of restless intellectual energy.

At the end of his lecture, Willard commented how the digital photograph albums we increasingly produce in the name of improved access distort and oversimplify our understanding of the act of remembering. It is a tragedy how so much of what we do in the digital humanities denies the possibility of reinventing and changing the textual and other forms we have inherited. Our ‘digital scholarly editions’ are so conservatively conceived that they would be recognized and understood by the Grimm Brothers; we continue to use the calendar form, deeply bound up with print technology, to reproduce abridgements of historical documents; our collections of images are little more than photograph albums. Is the computer really no more than a digital photocopier? Does our digital humanities work explore whether it has greater potentiality? If we are to embrace Willard’s vision of a more intellectually restless and experimental digital humanities, we need to abandon many of the assumptions we have made about what we do in the digital humanities. Building endless numbers of unimaginative, repetitive, stereotyped and hidebound projects is not enough. As digital humanities develops, it is difficult to escape the suspicion that for many the routine creation of digital projects or the cutting and slicing of data provides a quiet peaceful haven, where we can code quietly without the risk of demanding intellectual challenges or complex theoretical considerations. Data is too often at the moment seen as a substitute for thought. Willard’s fundamental message is that digital humanities should be intellectually demanding and challenging, posing fundamental philosophical and theoretical questions at every turn. Willard describes here the intellectual constituency of the digital humanities, and it is the exploration and investigation of this constituency which should be our concern. We can discuss pointlessly and forever how big and what shape the text of the digital humanities should be (and what the labels on the door mean), but in the end it is only the conversations that take place within it which count.

In the Footsteps of Boulton and Watt


 I've been thinking a lot lately about a theme I broached in my inaugural lecture, the parallels between the industrial and agricultural changes in Britain in the late 18th and 19th centuries and the current digital revolution. I feel that the changes associated with the Industrial Revolution give us a better framework for interpreting present changes than the arrival of print in Western Europe in the 15th century.

I want to explore these themes more deeply in my keynote for the Sheffield Digital Humanities Congress in September, but when I was invited to speak at Birmingham City University at the excellent InterFace conference, organised by a talented group of postgraduates (and many thanks to Tychonas Michailidis for the excellent arrangements), it seemed a perfect opportunity to try out some of my ideas in the city of Matthew Boulton and James Watt.

I became fascinated by Watt's project to build a Sculpture Copying Machine, which, with Watt's proposed use of artificial stone in liquid form, seemed extraordinarily like 3D printing. The way in which a team from the Science Museum and from UCL had afterwards used 3D scanning to recreate a bust of Watt from moulds found in his workshop seemed to bring the story full circle.

The slides from my talk to InterFace are available here.

It was very worthwhile trying out these ideas in Birmingham - I had some helpful and constructive response from the audience, but using history to make comments on current digital cultures is complex. Space makes it difficult to avoid turning the discussion of figures like Watt into a eulogy in the manner of a latter-day Samuel Smiles. In considering how history helps us understand the digital, its striking how the history can lose out. It was useful to have had some practice in trying to balance this out before I hit Sheffield in September...

Geo600: Gravity's Rainbow


I have a worry that this blog could start to assume a very elderly and curmudgeonly tone, and that I will start to establish myself as a sort of digital Victor Meldrew. I certainly feel that it is one of the roles of the digital humanities scholar to try and counter the kind of puppyish techno-enthusiasm which seems to believe that Twitter (or Tumblr or Instagram or whatever is next) can solve the problems of humanity. The digital humanities should be a means by which more rigorous critical and theoretical perspectives can be brought to bear on our engagement with the changing digital world. We should want to own an iPad and feel that we can make use of it (strongly yes on both counts for me), but we should also recognize that as a cultural, political and social object, the iPad raises lots of very challenging questions as to how knowledge will be controlled, commodified and mediated in the future. However, in developing such critical perspectives, there is a risk of losing one’s enthusiasm for innovation. In its earliest days, humanities computing was notable for the way in which it was constantly pushing forward the envelope and trying new things. I wonder whether we have lost something of that spirit.

I was prompted to reflect on the importance of innovation by a fascinating article in yesterday’s newspaper about a remarkable project to detect gravitational waves. The newspaper described the project as Anglo-German, but two of the main collaborators in Geo600 are based in the Physics Department at my former home of the University of Glasgow, and I wish I had known about the project while I was at Glasgow, because I would have beaten a path straight to its door.

I’ll try to summarise the project which, since I only scraped an O-level in Physics, will be, I'm sure, an inept and crude account. Einstein proposed that big stellar events like supernovae send out gravitational waves which sweep through the universe. However according to Einstein these waves would be so weak that it would be impossible ever to detect them. Thus, when light from the supernova explosion that formed the Crab Nebula reached the earth in 1054, at about the same time a gravitational wave would also have reached the earth, but its effect would have been barely perceptible.

The Geo600 project is attempting to achieve what Einstein thought impossible – to measure the impact of these gravitational waves. In order to do so, it is necessary to design and construct incredibly sensitive detectors,  capable of detecting changes which would cause the detector to move by only a few hundred billion-billionths of a metre. The detectors that have been built are so sensitive that they show the effect of the waves pounding on the beach fifty miles away, or will be affected by the gravitational pull of a person walking past. If these detectors are successful, they will prove Einstein right in predicting the existence of gravitational waves, but wrong in thinking that these waves could never be detected. Verifying an important aspect of the Speial Theory of Relatively is clearly valuable enough as a scientific outcome, but the Geo600 project proposes also completely to transform the nature of astronomy. To quote Professor Jim Hough at Glasgow: ‘We are going to create a completely new kind of astronomy…  Until now, everything we have learned about the universe has been based on studies of electromagnetic radiation – from infrared to visible light to gamma ray detection. Gravity waves will create a completely new type of astronomy’.

The humble humanities scholar may feel that she or he will never need or want to develop such ambitious projects. But reading the article on gravitational waves made my mind run back to a quotation from Charles Babbage, the Victorian pioneer of computing, that I used in a talk at the University of Kentucky in 1995. Here’s what I said then:

"In the Ninth Bridgewater Treatise, Babbage pointed out how a knowledge of mechanical laws gives you a different view of the world. When you speak, the waves spread out, gradually losing strength and impetus, but still remaining, until the only trace is perhaps in the movement of molecules, but still there. Likewise, the cries of a drowning man would create sound waves which would spread out through the water, until only the water atoms retained the impression of them. With a sufficiently powerful computer, Babbage speculated, you might be able to detect those faint traces and recover the last words of the dying man. This would be true of any object - the Beowulf manuscript would retain the faint impression of the conversations the scribe had while writing it. That is the meaning of the phrase I suggested to Kevin as a motto for this conference, and which Ackroyd also uses in his novel: 'Every atom, impressed with good and with ill, retains at once the motions which philosophers and sages have imparted to it, mixed and combined in ten thousand ways with all that is worthless and base. The air itself is one vast library, on whose pages are for ever written all that man has ever said or woman whispered.' Babbage's notion that you could recapture those words must have seemed bizarre in 1837, but in these days of chaos theory it seems less strange. Perhaps one day we will hear the Beowulf scribe speaking. There is certainly a challenge there which I think we should take up".

This image that ‘the air itself is one vast library’ was also taken up, I noticed, by James Gleick in The Information. If we can detect gravitational waves, can’t we also detect sound waves from the past, and open up the vast library in the air? Is it really so impracticable? Isn’t this the kind of innovation that the digital humanities should be working with physicists and other scientists to take forward? It seems that we don’t develop visionary research in the humanities on the same scale as in the sciences.  It is this kind of visionary research, the ‘big humanities’, that scholars in the digital humanities should be arguing the case for.    

Postscript 17 August 2012

The idea that in some way sounds of the past can be recaptured from the air occurred to others apart from Babbage. Friedrich Kittler's challenging and celebrated work, Gramophone, Film, Typewriter reproduces  Salomo Friendlaender's short story, 'Goethe Speaks into the Phonograph' (1916). This takes the idea that the air in a room where Goethe once spoke would still retain the impression of the waves generated by his voice, but adds a grotesque aspect by suggesting that, in order to recreate Goethe's voice, it would be necessary for the airwaves to be directed across Goethe's vocal chords (which fortunately had been preserved after his death). For Kittler, the idea of recapturing these historic sound waves from the air reflected the awareness of sound waves created by the discovery of the gramophone. If the abiding image of the digital is the binary opposition of one/off, the gramophone reflected the triumph of the analogue unit of the wave. In a sense, this idea of recapturing the past from soundwaves in the air might be seen as an analogue fantasy.
