First major literary work (Chaucer’s Canterbury Tales) developed as an app

I wanted something completely different today and found it in a May 2, 2020 article, by Lucie Laumonier for University Affairs, about a multimedia app featuring the Canterbury Tales narrated in middle English,

Four historians from Canada and England have launched the General Prologue app, the first app featuring an audio performance of Geoffrey Chaucer’s The Canterbury Tales in its original 14th-century English.

“Here bygynneth the Book of the tales of Caunterbury,” says the expressive voice of the narrator. The strange Middle English words comprise the opening verse of the medieval masterpiece composed by Chaucer more than 600 years ago. The app, which launched on February 3, is available for iOS and Android users, and through a dedicated website.

A February 2, 2020 University of Saskatchewan news release (also on EurekAlert), announced news of the app’s launch and the international collaboration, which included an academic at University College London (UCL), and the late Terry Jones (of Monty Python fame),

A University of Saskatchewan-led international team has produced the first web and mobile phone app of Geoffrey Chaucer’s The Canterbury Tales–the first major literary work augmented by new scholarship, in any language, presented in an app.

“We want the public, not just academics, to see the manuscript as Chaucer would have likely thought of it–as a performance that mixed drama and humor,” said University of Saskatchewan (USask) English professor Peter Robinson, leader of the project.

“We have become convinced, over many years, that the best way to read the Tales is to hear it performed–just as we imagine that Chaucer himself might have performed it at the court of Richard II.”

The free app is the first edition in a planned series. The app features a 45-minute audio performance of the General Prologue of the Tales–the masterpiece work by the most important English writer before Shakespeare–along with the digitized original manuscript. While listening to the reading, users have access to supporting content such as a translation in modern English, commentary, notes and vocabulary explaining Middle English words used by Chaucer.

The app, an offshoot of Robinson’s 25-year work to digitize the Canterbury Tales, contains key new research work. This includes a new edited text of the Prologue created by USask sessional lecturer Barbara Bordalejo, a new reading of the Tales by former USask student Colin Gibbings, and new findings about the Tales by UCL (University College London) medievalist professor Richard North. The National Library of Wales offered its digitized version of the Prologue‘s original manuscript for the app.

The late Monty Python star Terry Jones, who was a medievalist with two influential books on Chaucer, was also instrumental in developing the content of the app. His translation of The General Prologue and his books feature in the introduction and notes. This work on the app is thought to have been the last major academic project that Jones worked on before his passing on January 21.

The app was released on Android and Apple IoS just after Jones’ birthday on February 1st, in celebration of Jones’ academic work.

“We were so pleased that Terry was able to see and hear this app in the last weeks of his life. His work and his passion for Chaucer was an inspiration to us,” said Robinson, whose work on the Tales has been supported by USask and by the federal Social Sciences and Humanities Research Council (SSHRC). “We talked a lot about Chaucer and it was his idea that the Tales would be turned into a performance.”

Because Chaucer left the Tales unfinished at his death, there is no single text of the Tales, and scholars have to re-construct the text from over 80 distinct manuscripts, mostly written by hand before 1500.

“While the app has material which should be of interest to every Chaucer scholar, it is particularly designed to be useful to people reading Chaucer for the first time. These include not only bachelor of arts university students and school children but also members of the public who have their own interest in Chaucer and his works,” said UCL’s North.

Robinson’s Canterbury Tales project, based at USask since 2010, includes several students who are transcribing all 30,000 pages of the manuscripts into the computer to discover how they are related to each other and to Chaucer’s lost original.

“The app is important for people who do not know the history behind the production of the Canterbury Tales, and to understand how the modern concept of author didn’t exist back then,” said Robinson. “We have many manuscripts copied by hand over time, and the Canterbury Tales Project hopes to establish where they come from, how they were created and who produced them as part of that history.”

Robinson said that the team has ready materials to develop at least two more apps, in particular Miller’s Tale, the second story in the Canterbury Tales.

The General Prologue app was built around the Hengwrt manuscript of the Tales, commonly regarded as the best source for Chaucer’s text and held at The National Library of Wales. The specialist preservation and digitization work undertaken at The National Library of Wales enabled the images of the original manuscript to be presented with supporting content for readers via the app.

North’s academic research on the project includes several new discoveries. For instance, he has found evidence suggesting that Chaucer’s Knight, one of the main characters of the Tales, is at the siege of Algeciras near Gilbraltar, in the south of Spain, in 1369 instead of the commonly assumed date 1342-44.

North believes that putting the Knight at this siege puts his age nearer to 50 years old when the reader encounters him with the other pilgrims in the Tabard in the General Prologue–about the age of Chaucer himself.

Brigit Katz covered the story in a February 5, 2020 article for Smithsonian Magazine. Medievallists.net also posted a story (no date) which included two trailers for the app (you’ll find a 1:39 trailer below),

Here’s where you’ll find the app and more,

Enjoy! And for those who caught it, “something completely different” was a reference to Monty Python’s “And Now for Something Completely Different.”

A question of consciousness: Facebotlish (a new language); a July 5, 2017 rap guide performance in Vancouver, Canada; Tom Stoppard’s play; and a little more

This would usually be a simple event announcement but with the advent of a new, related (in my mind if no one else’s) development on Facebook, this has become a roundup of sorts.

Facebotlish (Facebook’s chatbots create their own language)

The language created by Facebook’s chatbots, Facebotlish, was an unintended consequence—that’s right Facebook’s developers did not design a language for the chatbots or anticipate its independent development, apparently.  Adrienne LaFrance’s June 20, 2017 article for theatlantic.com explores the development and the question further,

Something unexpected happened recently at the Facebook Artificial Intelligence Research lab. Researchers who had been training bots to negotiate with one another realized that the bots, left to their own devices, started communicating in a non-human language.

In order to actually follow what the bots were saying, the researchers had to tweak their model, limiting the machines to a conversation humans could understand. (They want bots to stick to human languages because eventually they want those bots to be able to converse with human Facebook users.) …

Here’s what the language looks like (from LaFrance article),

Here’s an example of one of the bot negotiations that Facebook observed:Bob: i can i i everything else . . . . . . . . . . . . . .
Alice: balls have zero to me to me to me to me to me to me to me to me to
Bob: you i everything else . . . . . . . . . . . . . .
Alice: balls have a ball to me to me to me to me to me to me to me
Bob: i i can i i i everything else . . . . . . . . . . . . . .
Alice: balls have a ball to me to me to me to me to me to me to me
Bob: i . . . . . . . . . . . . . . . . . . .
Alice: balls have zero to me to me to me to me to me to me to me to me to
Bob: you i i i i i everything else . . . . . . . . . . . . . .
Alice: balls have 0 to me to me to me to me to me to me to me to me to
Bob: you i i i everything else . . . . . . . . . . . . . .
Alice: balls have zero to me to me to me to me to me to me to me to me to

It is incomprehensible to humans even after being tweaked, even so, some successful negotiations can ensue.

Facebook’s researchers aren’t the only one to come across the phenomenon (from LaFrance’s article; Note: Links have been removed),

Other AI researchers, too, say they’ve observed machines that can develop their own languages, including languages with a coherent structure, and defined vocabulary and syntax—though not always actual meaningful, by human standards.

In one preprint paper added earlier this year [2017] to the research repository arXiv, a pair of computer scientists from the non-profit AI research firm OpenAI wrote about how bots learned to communicate in an abstract language—and how those bots turned to non-verbal communication, the equivalent of human gesturing or pointing, when language communication was unavailable. (Bots don’t need to have corporeal form to engage in non-verbal communication; they just engage with what’s called a visual sensory modality.) Another recent preprint paper, from researchers at the Georgia Institute of Technology, Carnegie Mellon, and Virginia Tech, describes an experiment in which two bots invent their own communication protocol by discussing and assigning values to colors and shapes—in other words, the researchers write, they witnessed the “automatic emergence of grounded language and communication … no human supervision!”

The implications of this kind of work are dizzying. Not only are researchers beginning to see how bots could communicate with one another, they may be scratching the surface of how syntax and compositional structure emerged among humans in the first place.

LaFrance’s article is well worth reading in its entirety especially since the speculation is focused on whether or not the chatbots’ creation is in fact language. There is no mention of consciousness and perhaps this is just a crazy idea but is it possible that these chatbots have consciousness? The question is particularly intriguing in light of some of philosopher David Chalmers’ work (see his 2014 TED talk in Vancouver, Canada: https://www.ted.com/talks/david_chalmers_how_do_you_explain_consciousness/transcript?language=en runs roughly 18 mins.); a text transcript is also featured. There’s a condensed version of Chalmers’ TED talk offered in a roughly 9 minute NPR (US National Public Radio) interview by Gus Raz. Here are some highlights from the text transcript,

So we’ve been hearing from brain scientists who are asking how a bunch of neurons and synaptic connections in the brain add up to us, to who we are. But it’s consciousness, the subjective experience of the mind, that allows us to ask the question in the first place. And where consciousness comes from – that is an entirely separate question.

DAVID CHALMERS: Well, I like to distinguish between the easy problems of consciousness and the hard problem.

RAZ: This is David Chalmers. He’s a philosopher who coined this term, the hard problem of consciousness.

CHALMERS: Well, the easy problems are ultimately a matter of explaining behavior – things we do. And I think brain science is great at problems like that. It can isolate a neural circuit and show how it enables you to see a red object, to respondent and say, that’s red. But the hard problem of consciousness is subjective experience. Why, when all that happens in this circuit, does it feel like something? How does a bunch of – 86 billion neurons interacting inside the brain, coming together – how does that produce the subjective experience of a mind and of the world?

RAZ: Here’s how David Chalmers begins his TED Talk.

(SOUNDBITE OF TED TALK)

CHALMERS: Right now, you have a movie playing inside your head. It has 3-D vision and surround sound for what you’re seeing and hearing right now. Your movie has smell and taste and touch. It has a sense of your body, pain, hunger, orgasms. It has emotions, anger and happiness. It has memories, like scenes from your childhood, playing before you. This movie is your stream of consciousness. If we weren’t conscious, nothing in our lives would have meaning or value. But at the same time, it’s the most mysterious phenomenon in the universe. Why are we conscious?

RAZ: Why is consciousness more than just the sum of the brain’s parts?

CHALMERS: Well, the question is, you know, what is the brain? It’s this giant complex computer, a bunch of interacting parts with great complexity. What does all that explain? That explains objective mechanism. Consciousness is subjective by its nature. It’s a matter of subjective experience. And it seems that we can imagine all of that stuff going on in the brain without consciousness. And the question is, where is the consciousness from there? It’s like, if someone could do that, they’d get a Nobel Prize, you know?

RAZ: Right.

CHALMERS: So here’s the mapping from this circuit to this state of consciousness. But underneath that is always going be the question, why and how does the brain give you consciousness in the first place?

(SOUNDBITE OF TED TALK)

CHALMERS: Right now, nobody knows the answers to those questions. So we may need one or two ideas that initially seem crazy before we can come to grips with consciousness, scientifically. The first crazy idea is that consciousness is fundamental. Physicists sometimes take some aspects of the universe as fundamental building blocks – space and time and mass – and you build up the world from there. Well, I think that’s the situation we’re in. If you can’t explain consciousness in terms of the existing fundamentals – space, time – the natural thing to do is to postulate consciousness itself as something fundamental – a fundamental building block of nature. The second crazy idea is that consciousness might be universal. This view is sometimes called panpsychism – pan, for all – psych, for mind. Every system is conscious. Not just humans, dogs, mice, flies, but even microbes. Even a photon has some degree of consciousness. The idea is not that photons are intelligent or thinking. You know, it’s not that a photon is wracked with angst because it’s thinking, oh, I’m always buzzing around near the speed of light. I never get to slow down and smell the roses. No, not like that. But the thought is, maybe photons might have some element of raw subjective feeling, some primitive precursor to consciousness.

RAZ: So this is a pretty big idea – right? – like, that not just flies, but microbes or photons all have consciousness. And I mean we, like, as humans, we want to believe that our consciousness is what makes us special, right – like, different from anything else.

CHALMERS: Well, I would say yes and no. I’d say the fact of consciousness does not make us special. But maybe we’ve a special type of consciousness ’cause you know, consciousness is not on and off. It comes in all these rich and amazing varieties. There’s vision. There’s hearing. There’s thinking. There’s emotion and so on. So our consciousness is far richer, I think, than the consciousness, say, of a mouse or a fly. But if you want to look for what makes us distinct, don’t look for just our being conscious, look for the kind of consciousness we have. …

Intriguing, non?

“Utterly unique… both brilliantly entertaining and hugely informative” ★ ★ ★ ★ ★ – Broadway Baby

“An education, inspiring, and wonderfully entertaining show from beginning to end” ★ ★ ★ ★ ★ – Mumble Comedy

There’s quite the poster for this rap guide performance,

In addition to  the Vancouver and Edinburgh performance (the show was premiered at the Brighton Fringe Festival in May 2017; see Simon Topping’s very brief review in this May 10, 2017 posting on the reviewshub.com), Brinkman is raising money (goal is $12,000US; he has raised a little over $3,000 with approximately one month before the deadline) to produce a CD. Here’s more from the Rap Guide to Consciousness campaign page on Indiegogo,

Brinkman has been working with neuroscientists, Dr. Anil Seth (professor and co-director of Sackler Centre for Consciousness Science) and Dr. Heather Berlin (Brinkman’s wife as noted earlier; see her Wikipedia entry or her website).

There’s a bit more information about the rap project and Anil Seth in a May 3, 2017 news item by James Hakner for the University of Sussex,

The research frontiers of consciousness science find an unusual outlet in an exciting new Rap Guide to Consciousness, premiering at this year’s Brighton Fringe Festival.

Professor Anil Seth, Co-Director of the Sackler Centre for Consciousness Science at the University of Sussex, has teamed up with New York-based ‘peer-reviewed rapper’ Baba Brinkman, to explore the latest findings from the neuroscience and cognitive psychology of subjective experience.

What is it like to be a baby? We might have to take LSD to find out. What is it like to be an octopus? Imagine most of your brain was actually built into your fingertips. What is it like to be a rapper kicking some of the world’s most complex lyrics for amused fringe audiences? Surreal.

In this new production, Baba brings his signature mix of rap comedy storytelling to the how and why behind your thoughts and perceptions. Mixing cutting-edge research with lyrical performance and projected visuals, Baba takes you through the twists and turns of the only organ it’s better to donate than receive: the human brain. Discover how the various subsystems of your brain come together to create your own rich experience of the world, including the sights and sounds of a scientifically peer-reviewed rapper dropping knowledge.

The result is a truly mind-blowing multimedia hip-hop theatre performance – the perfect meta-medium through which to communicate the dazzling science of consciousness.

Baba comments: “This topic is endlessly fascinating because it underlies everything we do pretty much all the time, which is probably why it remains one of the toughest ideas to get your head around. The first challenge with this show is just to get people to accept the (scientifically uncontroversial) idea that their brains and minds are actually the same thing viewed from different angles. But that’s just the starting point, after that the details get truly amazing.”

Baba Brinkman is a Canadian rap artist and award-winning playwright, best known for his “Rap Guide” series of plays and albums. Baba has toured the world and enjoyed successful runs at the Edinburgh Fringe Festival and off-Broadway in New York. The Rap Guide to Religion was nominated for a 2015 Drama Desk Award for “Unique Theatrical Experience” and The Rap Guide to Evolution (“Astonishing and brilliant” NY Times), won a Scotsman Fringe First Award and a Drama Desk Award nomination for “Outstanding Solo Performance”. The Rap Guide to Climate Chaos premiered in Edinburgh in 2015, followed by a six-month off-Broadway run in 2016.

Baba is also a pioneer in the genre of “lit-hop” or literary hip-hop, known for his adaptations of The Canterbury Tales, Beowulf, and Gilgamesh. He is a recent recipient of the National Center for Science Education’s “Friend of Darwin Award” for his efforts to improve the public understanding of evolutionary biology.

Anil Seth is an internationally renowned researcher into the biological basis of consciousness, with more than 100 (peer-reviewed!) academic journal papers on the subject. Alongside science he is equally committed to innovative public communication. A Wellcome Trust Engagement Fellow (from 2016) and the 2017 British Science Association President (Psychology), Professor Seth has co-conceived and consulted on many science-art projects including drama (Donmar Warehouse), dance (Siobhan Davies dance company), and the visual arts (with artist Lindsay Seers). He has also given popular public talks on consciousness at the Royal Institution (Friday Discourse) and at the main TED conference in Vancouver. He is a regular presence in print and on the radio and is the recipient of awards including the BBC Audio Award for Best Single Drama (for ‘The Sky is Wider’) and the Royal Society Young People’s Book Prize (for EyeBenders). This is his first venture into rap.

Professor Seth said: “There is nothing more familiar, and at the same time more mysterious than consciousness, but research is finally starting to shed light on this most central aspect of human existence. Modern neuroscience can be incredibly arcane and complex, posing challenges to us as public communicators.

“It’s been a real pleasure and privilege to work with Baba on this project over the last year. I never thought I’d get involved with a rap artist – but hearing Baba perform his ‘peer reviewed’ breakdowns of other scientific topics I realized here was an opportunity not to be missed.”

Interestingly, Seth has another Canadian connection; he’s a Senior Fellow of the Azrieli Program in Brain, Mind & Consciousness at the Canadian Institute for Advanced Research (CIFAR; Wikipedia entry). By the way, the institute  was promised $93.7M in the 2017 Canadian federal government budget for the establishment of a Pan-Canadian Artificial Intelligence Strategy (see my March 24, 2017 posting; scroll down about 25% of the way and look for the highlighted dollar amount). You can find out more about the Azrieli programme here and about CIFAR on its website.

The Hard Problem (a Tom Stoppard play)

Brinkman isn’t the only performance-based artist to be querying the concept of consciousness, Tom Stoppard has written a play about consciousness titled ‘The Hard Problem’, which debuted at the National Theatre (UK) in January 2015 (see BBC [British Broadcasting Corporation] news online’s Jan. 29, 2015 roundup of reviews). A May 25, 2017 commentary by Andrew Brown for the Guardian offers some insight into the play and the issues (Note: Links have been removed),

There is a lovely exchange in Tom Stoppard’s play about consciousness, The Hard Problem, when an atheist has been sneering at his girlfriend for praying. It is, he says, an utterly meaningless activity. Right, she says, then do one thing for me: pray! I can’t do that, he replies. It would betray all I believe in.

So prayer can have meanings, and enormously important ones, even for people who are certain that it doesn’t have the meaning it is meant to have. In that sense, your really convinced atheist is much more religious than someone who goes along with all the prayers just because that’s what everyone does, without for a moment supposing the action means anything more than asking about the weather.

The Hard Problem of the play’s title is a phrase coined by the Australian philosopher David Chalmers to describe the way in which consciousness arises from a physical world. What makes it hard is that we don’t understand it. What makes it a problem is slightly different. It isn’t the fact of consciousness, but our representations of consciousness, that give rise to most of the difficulties. We don’t know how to fit the first-person perspective into the third-person world that science describes and explores. But this isn’t because they don’t fit: it’s because we don’t understand how they fit. For some people, this becomes a question of consuming interest.

There are also a couple of video of Tom Stoppard, the playwright, discussing his play with various interested parties, the first being the director at the National Theatre who tackled the debut run, Nicolas Hytner: https://www.youtube.com/watch?v=s7J8rWu6HJg (it runs approximately 40 mins.). Then, there’s the chat Stoppard has with previously mentioned philosopher, David Chalmers: https://www.youtube.com/watch?v=4BPY2c_CiwA (this runs approximately 1 hr. 32 mins.).

I gather ‘consciousness’ is a hot topic these days and, in the venacular of the 1960s, I guess you could describe all of this as ‘expanding our consciousness’. Have a nice weekend!

Carbon nanotubes the natural way; weaving carbon nanotubes into heaters; how designers think; robotic skin

Today I’ll be focusing, in a very mild way, on carbon nanotubes. First, a paper in Astrophysical Journal Letters (Feb. 2010 issue) titled, The Formation of Graphite Whiskers in the  Primitive Solar Nebula, is where an international team of scientists have shared an intriguing discovery about carbon nanotubes. From the news item on physorg.com,

Space apparently has its own recipe for making carbon nanotubes, one of the most intriguing contributions of nanotechnology here on Earth, and metals are conspicuously missing from the list of ingredients.

[Joesph] Nuth’s team [based at NASA’s Goddard Space Flight Center] describes the modest chemical reaction. Unlike current methods for producing carbon nanotubes—tiny yet strong structures with a range of applications in electronics and, ultimately, perhaps even medicine—the new approach does not need the aid of a metal catalyst. “Instead, nanotubes were produced when graphite dust particles were exposed to a mixture of carbon monoxide and hydrogen gases,” explains Nuth.

The structure of the carbon nanotubes produced in these experiments was determined by Yuki Kimura, a materials scientist at Tohoku University, Japan, who examined the samples under a powerful transmission electron microscope. He saw particles on which the original smooth graphite gradually morphed into an unstructured region and finally to an area rich in tangled hair-like masses. A closer look with an even more powerful microscope showed that these tendrils were in fact cup-stacked carbon nanotubes, which resemble a stack of Styrofoam cups with the bottoms cut out.

Since metals are used as catalysts for creating carbon nanotubes, this discovery hints at the possibility of a ‘greener’ process. In conjunction with the development at McGill (mentioned on this blog here) for making chemical reactions greener by using new nonmetallic catalysts, there may be some positive environmental impacts due to nanotechnology.

Meanwhile here on earth, there’s another new carbon nanotube development and this time it has to do with the material’s conductivity. From the news item on Nanowerk,

An interesting development using multifilament yarns is a new fabric heater made by weaving CNTEC® conductive yarns from Kuraray Living Co., Ltd. This fabric generates heat homogeneously all over the surface because of its outstanding conductivity and is supposed to be the first commercial use of Baytubes® CNTs from Bayer MaterialScience in the Japanese market.

The fabric heater is lightweight and thin, compact and shows a long-lasting bending resistance. It can be used for instance for car seats, household electrical appliances, for heating of clothes and as an anti-freezing material. Tests revealed that it may for example be installed in the water storage tank of JR Hokkaido’s “Ryuhyo-Norokko” train. Inside this train the temperature drops to around -20 °C in wintertime, because so far no heating devices other than potbelly stoves are available. According to JR Hokkaido railway company the fabric heater performed well in preventing the water from freezing. A seat heating application of the fabric heater is still on trial on another JR Hokkaido train line. It is anticipated that the aqueous dispersions might as well be suitable for the compounding of various kinds of materials.

I sometimes suspect that these kinds of nanotechnology-enabled applications are going to change the world in such a fashion that our ancestors (assuming we survive disasters) will be able to understand us only dimly. The closest analogy I have is with Chaucer. An English-speaker trying to read The Canterbury Tales in the language that Chaucer used to write, Middle English, needs to learn an unfamiliar language.

On a completely different topic, Cliff Kuang at Fast Company has written an item on designers and the Myer-Briggs personality test (industrial designer Michael Roller’s website with his data),

Designers love to debate about what personality type makes for the best designer. So Michael Roller took the extra step of getting a bunch of designers to take the Myers Briggs personality test, and published the results …

In other words, designers are less akin to the stereotypical touchy-feely artist, and more like engineers who always keep the big picture in mind.

This reminds me of a piece I wrote up on Kevin Dunbar (here) and his work investigating how scientists think. He came to the conclusion that when they use metaphors and analogies to describe their work to scientists in specialties not identical to their own, new insights and breakthroughs can occur. (Note: he takes a more nuanced approach than I’m able to use in a single, descriptive sentence.) What strikes me is that scientists often need to take a more ‘artistic and intuitive’ [my words] approach to convey information if they are to experience true breakthroughs.

My last bit is an item about more tactile robotic skin. From the news item on the Azonano website,

Peratech Limited, the leader in new materials designed for touch technology solutions, has announced that they have been commissioned by the MIT Media Lab to develop a new type of electronic ‘skin’ that enables robotic devices to detect not only that they have been touched but also where and how hard the touch was.

The key to the sensing technology is Peratech’s patented ‘QTC’ materials. QTC’s, or Quantum Tunnelling Composites, are a unique new material type which provides a measured response to force and/or touch by changing its electrical resistance – much as a dimmer light switch controls a light bulb. This enables a simple electronic circuit within the robot to determine touch. Being easily formed into unique shapes – including being ‘draped’ over an object much like a garment might, QTC’s provide a metaphor [emphasis mine] for how human skin works to detect touch.

Yes, I found another reference to metaphors although this metaphor is being used to convey information to a nontechnical audience. As for the ‘graphite whiskers’ in the title for the article which opened this posting, it is another metaphor and here, I suspect, it’s being used to describe something to other scientists who have specialties that are not identical to the researchers’ (as per Kevin Dunbar’s work).
