Swearing with @cadigan, @gavingsmith & @cstross #worldcon #loncon3 Rat’s Monkey’s Ahem

Many pieces of work feature constructed swearing, such as frak in Battlestar Galactica and some of the more farcical attempts at science-oriented swearing in earlier science fiction. (Let’s not even start on Harry Harrison’s bowbidy-bowb.)
I’ve met Mihaela before, when she visited Australia, and she did a great job on keeping the panel going, as well as contributing some excellent swear words of her own. Of course, the authors present did a great job of swearing like a variety of troopers from a range of different timezones and militaries, but there are important aspects to this, which were also excellently covered.
The blurb for the panel reads:
Swearing in science fiction and fantasy is occasionally a minefield of anachronism, but then, there’s often nothing weirder than hearing someone yell “frak”. Or even worse, a teenage character that refuses to curse at all. This panel will explore swear words in the genres. What purpose does swearing have within a society? What purpose does it serve in fiction, and how important, or not, are profanities to the narrative? When are invented curses more (or less) effective than real (contemporary or historical) examples, and why?
The general feeling was that conveying emotion is important and that swearing is an important part of this. It feels really hollow when a hardened space pirate says something like “Oh, dash” and this matters when you’re trying to convey the sense of reality required to hold up the parachute silk of disbelief.
There is one issue, which I raised in question time. Given that many young people do not have the delightfully proper middle and upper-middle class upbringing we see so often in Young Adult fiction, it’s positively disingenuous to remove swearing from certain works because that is the world those kids are growing up in. When people have fewer words at their disposal, they make use of the ones that they have. We know that children in the US from non-educationally successful backgrounds, with few books, can have a vocabulary deficit measured in the thousands of words and, probably, a lot of their emotional conveyance is going to come from the use of swearwords, whether we like it or not.
When someone picks up a book, they have to have a reason to keep reading, either by seeing themselves in there or just being really interested. When YA is a sterile “Boy’s Own” adventure of “Gosh” and “Golly”, this would seem farcical to a teen who is told to take out the f-ing garbage at night or they’d be in the s*. (Bowdlerised to keep my blog’s general rating, embarrassingly enough.) There’s an important issue in reaching the reluctant reader and we’re already aware of how much certain areas of education, such as Computer Science, have to be hidden from peer groups for not being perceived as “cool” enough.
I’m not recommending that Harry Potter has to start calling Ron an *#&*&#$@ piece of #(*#$ that wouldn’t *&#($ in a (()#$# )()#$, but there is a wider world that swearing can constructively reach, if we’re going to try and engage some of these borderline readers. (Of course, the frequency of pseudo-racist slurs between pure bloods and non- in the Potter world is astoundingly awful when you come to think about it, but I’m not actually as positive on that. There’s a big difference between giving people a voice that sounds like theirs and having a large number of cheerful racists mostly getting away with constant, casual racism.)
Panellists may have a completely different opinion on this so I welcome followups! Thank you!
Memories in Amber: How I possibly mildly embarrassed Christopher Priest by Emphasising the Influence of His Writing. #loncon3 #worldcon
Posted: September 4, 2014 Filed under: Education, Opinion | Tags: an infinite summer, christopher priest, contemplation, education, fiction, higher education, Infinite Summer, loncon3, students, summer, thinking, time travel, worldcon Leave a commentMany, many years ago, I read a short story about a young man and woman who, on an English Summer’s day, are frozen in time by visitors from elsewhere, probably the future. There’s a good story that follows, which I won’t go into here, and I really enjoyed it. The only problem was that I read it when I was about 10 and I was at someone else’s house, flicking through their book collection. After that point, although I remembered the story, I did not remember either the title or the author.
Now, this begin before the age of easy searching, I really had no simple way to find the story, unless someone else had read it and recognised my telling of it. When you tell your version of a story to someone else, it’s much like when you make a map – you put the things that interest you on there and this often reveals how much difference there is in interpretation.
Some years went by, probably about 25 or so, and I had taken to browsing collections of short stories in second hand book stores, looking for the work. It wasn’t a full-time occupation but, if I ran across a new store, I’d duck in and see what they had. I must have looked over about 10 countries, on three continents, idly looking for a story that I (by now) dimly remembered.
One day, I found it. The name of the story was “An Infinite Summer” by Christopher Priest, who was actually someone I had read and enjoyed for his novels, in a collection of the same name. I was so delighted after so many years of searching that the bookseller asked me what was up and, on hearing the story, gave the book to me for free.
And it’s still a great story. Character driven, well-written and with just enough time travel to make it work, without bogging down in the unnecessary mechanics of impossible machines.
Let’s move forward to this year, some 10 years later, and I happen to be at LonCon3, the World Science Fiction Convention for 2014, in the room for the sessions “In Conversation: Naomi Alderman and Christopher Priest”. I’m rather excited as I’d never seen Priest in the flesh before and his story is a part of the unfolding of my life. It wasn’t exactly a Golden Fleece but it was definitely a plank on the ship!
So the conversation unfolds and, delightfully, Priest is fiery, smart, opinionated, unrepentantly definite about things that I also happen to be unapologetic about and then he talks about his writing.
“I don’t believe in aliens, space ships or time travel”, he says, which explains much of his work and its fascination with a very human future, devoid of most of the tricks that are used to bring tension into the narrative. But the time travel thing piqued my curiosity, because “An Infinite Summer” is a glorious tale of time and time lost, told within the mythical context of the endless English Summer.
Question time arrives and I pose a question: “You say you don’t believe in time travel but what about ‘An Infinite Summer’? That’s a fantastic time travel story!”
There’s a pause, some time for recollection, and he says” Well, yes, they stopped people in time.” A pause.
I went on, “But weren’t they people from the future?”
And he pauses again, nods, and there is a bit of a chuckle from the audience as the moderator notes that I appear to know that work better than he does now.
“Yes,” he says, “thank you.” I must be honest that his “thank you” sounded a little… cool but I suspect that this was because I was terribly embarrassed myself for putting him in that position.
And yet, what a testament to the strength of the original work and its concept! There I am, transfixed and frozen in time at a moment where a much younger Christopher Priest is writing this story – this story reaches out to me and holds itself in my memory and it is a part of the mythology of my own life. Yet, he, having set the tableau down, moves on to do other things. This is “An Infinite Summer”, told with new players, and possibly, having written this down, somewhere it will be told again.
You never know how people are going to remember you and, in the short span that I’ve been blogging, it’s come back to me how some of my posts resonate deeply with people (not many) and they remember the contents more than I do. Yet I’m already moving on and looking ahead to other things. I should have known this because, as an educator, I sometimes have a bigger place in someone’s world than they do in mine – which I’m trying to change by getting to know my students better. I’m an okay person but I’m a lousy creature of myth.
I don’t actually think I bothered Mr Priest with this and I still love that story – now it’s helped me to realise and appreciate how your works can be seen over a lifetime but also, before I actually get much older, to realise that what I have done is another set of steps towards what I’m going to do.
Thank you, Christopher Priest, for a wonderful story, an experience that echoed it, and being extremely willing to participate with a community that obviously enjoys your work.
Being Honest About Stress, Challenge and Humanity: R U OK? Day #ruok

The RUOK™ logo from https://www.ruok.org.au
R U Ok? Day (September the 11th) is coming up soon, with its focus on reaching out and starting conversations with people that you think might not be ok, or might benefit from a friendly conversation. It’s a great initiative and, as someone who has struggled with mental illness, I’m so happy to see us talking openly about this. For me to out myself as having suffered with depression is no big thing, as I discuss it in other parts of the ‘net, but I realise that some of you might now look at what I do and what I say in a different light.
And, if you do, I have to tell you that you need to change the way that you think about these things. A very large number of humans will go through some form of mental issue in their lives, unsurprisingly given the levels of stress that we put ourselves under, the struggle some people have just to survive and the challenges that lie ahead of us as a rather greedy species on a finite globe. So, yes, I’ve suffered from depression but it is an illness. It is treatable and, when it is treated and managed, then you can’t tell that I have problems. In fact, like many people with the problem, even when I’m suffering, you wouldn’t really know. Nobody asks to get mentally ill so stigmatising, isolating and discriminating against people with a treatable mental condition is not just wrong, it’s pretty stupid. So let’s get beyond this and start talking, openly.
That’s where RUOK? is great because it gives you a day and some agency to reach out to someone who seems a little … off and ask them if they’re ok. Trust me when I say that 99% of them will appreciate it. Yes, 1% might give you some grief but if I knew a bet would pay off 99% of the time, I’d take it. The web site has some great tips for starting conversations so please read them if you’re thinking about doing this. (Pro tip: starting a conversation with “You should just cheer up” is not a great way to start. Or finish. In fact, just scratch that and try again.)
I am very open with my students, which I know some people think is potentially unprofessional, and I am a strong believer in cognitive apprenticeship. We are, pretty much, all the same in many respects and me pretending that everything I do comes fully formed and perfect from my amazing brain is a lie. My wisdom, such as it is, is the accumulated memory of the mistakes I’ve made that haven’t killed me yet. My students need to know that the people around them struggle, wonder, stress out and, quite frequently, rise above it all to keep on doing wonderful and beautiful things. I am still professional but I am honest and I am human.
I want to share with all of you something that I wrote on the death of Robin Williams, which I’ve edited slightly for language, but it’s been shared a lot over my other social feeds so it obviously resonates with people. However, many of my students won’t have seen it because I keep my private social life and ‘work’ social media separated. So here it is. I hope that you find it useful and, if you need help, maybe nudges you to help, and if you know someone you’re worried about, it inspires you to ask them “R U OK?”
Mental illness is a poisonous and weird thing. If your eyes changed function, you’d see things differently. When your brain changes function, everything gets weird – and the only impression you have of the perceptual world is suddenly flawed and untrustworthy. But it’s a biochemical issue like diabetes – regulatory systems that aren’t working properly and cannot just be “got over” by thinking happily. Ask a diabetic whether they’ve “really tried” to handle their sugar and see how far that gets you. 🙂
I wrote something, years ago, that I’ve never posted, to try and explain why some people just can’t stay. The nastiest thing about mental illness is that it can show you a world and a way of thinking that makes suicide apparently logical and, even more sadly, necessary. If you saw that world, then maybe you wouldn’t stay either. This doesn’t make it easier on the survivors but it’s important to recognise the role that an actual illness plays here. That f***ing ba***rd, cancer, takes people from us all the time but it at least has the decency to wield the knife itself. Depression puts the knife in the hands of its victim and makes it look like calculated agency, which hurts the people left behind even more.
There is no magic bullet for helping people with mental illness. Some need visible support. Some need solitude. Some need to work. Some drown in it. That’s because mental illness affects people, in all of their variety and their glorious irrationality, and I am no more a poster child for depression than anyone else. I can’t even tell you how to help me and, given how much I communicate, that’s the most irritating thing of all. But I do know that the ongoing support of caring people who are watching and listening makes a big difference and those of you who are aware and supporting, you keep up that good work! (And thank you, on behalf of the people who are still here because other people helped.)
It’s a sad day with Robin WIlliams passing but this is only a part of him. It’s a sad and mad part of him and I wish it hadn’t happened but I won’t let it define him, because his struggles were a part of him and his contribution to laughter and joy were so much greater. The least I can do is to see past his ‘mental diabetes’ to celebrate his actual talent and contribution. And offer my deepest sympathies and condolences to his family and friends.
Rest well, Robin.
Digital Humanities: Reflections on distant reading and why the ability to fly hasn’t stopped us walking.
Posted: August 17, 2014 Filed under: Education | Tags: close reading, colonisation, computer science, cultural colonisation, digital humanities, distant reading, education, higher education, humanities, italian Futurism, Marinetti 4 CommentsOne of the themes explored in the Digital Humanities is often “what exactly do we mean by Digital Humanities” because everyone asks and there are any number of self-described skeptics who seem to have an inability to add any new categories to their knowledge hierarchies. We’re studying the intersection of traditional computing and humanities so we’re asking the old question of “where does the desert end” which is only answered locally and specifically, rather than globally and generally. But a major fear for Humanists that came up during the week I was in Maryland was the threat of a colonising external force that would fundamentally alter what Humanists did until it was unrecognisable. I’m going to talk briefly about my view of digital humanities as a parallel augmentation, rather than a displacing colonisation.
Many areas of Humanities use the notion of close reading, where the text is carefully read and interpreted as part of a sustained effort. While this is exemplary for extracting themes and really getting into the work it doesn’t scale up well. We keep producing things to read and there is a limit as to how many things you can close read. This is where distant reading can come in, because it scans works thematically and syntactically, and provides an aggregate or abstraction to the reader. This is scalable and fast, because we can computerise it, but it risks inaccuracy, shallowness and is guaranteed to have the bias of the analysis software.
Let me step back and talk about travel for a moment. We started (well, by we, I mean bipedal humans) moving around on our feet. Then we did things with animals – in a vehicular sense – then the wheel, then lots of wheels, plus animals, plus betting – and that’s how we got the Colosseum. At some point, we stopped trying to put petrol into animals (who kept exploding) and tried it in cars intend. Suddenly we could zoom around, which widened our stride, but had the downside of enabling Italian Futurism at the start of the 20th century which led to all sorts of odd things and the declaration of war as the “great hygiene” until a lot of them died in the Great War – seriously, Marinetti, what were you thinking? (As a side note, the Futurist Cookbook is worth reading because it’s very Heston Blumenthal, just 90 years beforehand.)
Then we developed planes and the journey that took months on foot, weeks on animal and days by car, could take hours. But we never stopped walking, although we could now use our more advanced techniques to walk in new places and ultimately go further.
I feel exactly the same about close and distant reading. There are now (hooray) too many books on most subjects for any person to read in their life, let alone in a span to allow detailed analysis in a timely fashion. But this doesn’t mean we have to stop close reading. It means that we can look into topics and areas, refine our distant reading and visualisation, and then drill down once we’ve landed somewhere. Better still, distant reading allows us to link areas of close reading that may not be apparently connected – we can fly to a new place to explore that will develop the knowledge we already have.
Personally, I’d love it if the Humanities came and did a bit of colonisation in Computer Science, but I can completely understand why the reverse is culturally confronting. And I can also understand the many trad CS people who would also feel threatened by a counter-colonisation – although I probably don’t agree with their reasoning.
Going to a course like this is always good for my thinking as it requires me to switch gears and lens to get things done. I strongly recommend stepping out of the comfort zone of your own discipline when you can as it gives you extra knowledge and some valuable perspective.
Teaching in Hong Kong, Reflections
Posted: July 26, 2014 Filed under: Education | Tags: AsiaBound, Computer Emergency Response Team, computer security, CUHK, CUHK campus, education, evaluation, exams, exchange, higher education, Hong Kong, learning, Lee Woo Sing, Lee Woo Sing College, networking, podcasts, reflections, security, students, teaching, thinking Leave a commentI used to wait for a while before writing my reflections, to give myself time to sort the information and think about things. These days, one amazing thing finishes and then another starts. I’ve had a lot less free time than I thought I would on this course and I have about a day of downtime before starting work again on Monday (I fly back this afternoon) and then I’m off again on another project a week from then. So I’ll try and capture my thoughts now, although I always hope to come back and adjust them later as I think. (I actually have a maxim when I’m travelling to “do it while I’m there” because I’ve discovered that, too often, the way back takes you on a different path, so I may never revisit this but, knowing this, I’ll try to put in as much as I can.)
In talking to the students, and in seeing their marks, this has been a success but, like all pathfinders, the problem now is marking the trail so that other people can find it. How do we do this again? How do we it better? Well, we’re already talking about setting up the administration earlier to get some things going that we wanted the first time around and I’ve got a list of suggestions from the students as to what they think could be better.
But this was a strong validation of guided study groups, blended learning, flipping, collaborative work and giving students some freedom. This also justified putting the effort into industry visits and sharing what we do in our school with our students. This has been an excellent educational experience, with emphasis on both parts of that. The community has made it work, because the students commented that they’d never spent so much time digging into references to understand what was going on, and that discussion was an important part of that. However, their physical proximity allowed them to do it face-to-face, rather than on a forum.
That’s an interesting point – if you look at our electronic footprint, you’d think the course was a failure. Instead, because we spent at least 3-4 hours together every day, issues were resolved quickly and only broadcast when they had to be. You’d be right in assuming that that can be a little wearing on the instructor, because you’re always on, but that’s why I’m here.
The next trick is going to be getting this to work for less crazy instructors – in the last couple of days, I’ve been really tired, because the constant “on” (while doing my normal job back home in the cracks) is not what I’m used to and I don’t have my usual home comforts to settle back in to, in order to unwind. Not a big complaint, as I’ve been very comfortable, but a lot of people would find it hard to leave their families for three weeks, let alone act as mentor, guide and teacher to 10 people across that time. Having said that, the students have been great and I’ve worried more about them as a general principle than I’ve had to deal with as a reaction to problems. But it is still wearing.
Probably, the most important thing to do next time is to go ahead with the pan of integrating local students as well, to maximise the mix. Travel broadens the mind, because the longer you spend in other cultures, the more of your own you can start to see without your own biases. We’ve done very well in exposing students to different areas of HK and Macua, in seeing other communities and industries, and in meeting people – but this would be so much better if they worked side-by-side with students from CUHK. Apart from a learning experience, we could be building working and friendship relationships measured in decades rather than a trip measured in weeks.
In summary, it went well and we managed to combine engaging learning with effective learning – so I’m very happy to call this a successful start, already.
If you’ve been following the course, thanks for reading, and I’m always happy to answer questions in the comments! Ciao!
Take us out, Bruce!
Teaching in Hong Kong, Day 15 (Final Day)
Posted: July 26, 2014 Filed under: Education | Tags: alumni, AsiaBound, Computer Emergency Response Team, computer security, CUHK, CUHK campus, durian, education, exams, exchange, higher education, Hong Kong, learning, Lee Woo Sing, Lee Woo Sing College, networking, podcasts, security, students, teaching Leave a commentThe final day started a little late as we didn’t have as much to do. At 10am we kicked off with a quick end-of-course note from me, thanking the students for their enthusiasm and their participation, and their willingness to go along with the whole scheme. They, in turn, presented me with a very large book about cats (a running theme in the course and my own family contains three cats – where, by contains, I of course mean exists for the service of) which they had all inscribed. It was a delightful way to start the day!
Shally and Louis from the OAL came along and we presented them with gifts to thank them for all of their help and support during the last three weeks: Australian wine and excellent chocolate, in case you’re wondering. They, in turn, presented us with lemon cake, a CUHK dessert speciality, which is a sort of lemony.. frozen.. corn flakey… iced? treat that is deliciously indescribable! Thank you again to everyone at CUHK: Shally, Louis, Phoebe, Daniel and Cora, for all of your help while we’ve been here!
After a very pleasant 30 minutes, we got back to the final on-campus business, the quiz and the short-answer exam. With that concluded, I was able to inform the students to check their marks to look at their progress and some students will notice that they already have enough raw marks to pass – although they won’t stop now!
That concluded the course, except for a vegetarian dinner at a Buddhist “mock meat” restaurant in Hung Hom, arranged by David, our Alumni Ambassador for Hong Kong and China. The meal was astounding and we got take a double decker bus ride through Hung Hom from the MTR to get there – adding another experience into the mix! Here are some of the photos and dishes from the meal:
Here are two pictures with David serving from the (ample) banquet and the students enjoying themselves:
(The very small student is David’s daughter – Ashley.) Those of you with sharp eyes might recognise the fruit on the table as Durian – the King of Fruits and the fruit with one of the most amazing reputations. David went out specially to go and get two beautiful durians for the students to try something new (Kelvin and I needed no convincing as we are both strongly committed to the durian) and most people were very pleasantly surprised that the smell wasn’t as bad as they’d heard and that the taste was very much worth pursuing It is, however, amazingly rich, there’s a lot of the avocado richness concealed in the ultra-mango and (being honest) spring onion flavours of the durian.
Here’s the final picture of the course, standing proud in front of the defeated durian. We came to Hong Kong to learn, to experience and to have a lot of fun. And we did all three. Thank you, Hong Kong!
Teaching in Hong Kong, Day 14
Posted: July 25, 2014 Filed under: Education | Tags: AsiaBound, Computer Emergency Response Team, computer security, CUHK, CUHK campus, education, exams, exchange, heartbleed bug, higher education, Hong Kong, learning, Lee Woo Sing, Lee Woo Sing College, networking, podcasts, security, SSL, students, teaching, xkcd Leave a commentThursday the 24th was a very straightforward day as we were bringing most of the coursework to a close and moving into the evaluation phase – not just for the students but for the course itself. We started with a tutorial on security, where we went through a range of issues and looked into the most commonly occurring problems, as recorded by the Computer Emergency Response Team (CERT) webpage. A lot of the problems we get are caused by:
- Programmers not checking what users type into their programs.
- Programmers not properly limiting what programs send to each other.
- “Back door” exploits where hard-coded usernames and passwords are left in.
We had a chance to discuss white hat and black hat hacking – patching a bug will get you a small cheque and a shout out, reporting an exploit to a criminal syndicate can make you rich. (And hunted or dead, for that matter.) It’s an interesting area – ethically and academically.
I’d asked the students, on Tuesday, to pick an area of security to talk about for 5-10 minutes and this proved to be a really interesting activity, taking longer than the hour I’d allotted for it. Topics included the Stuxnet Worm, and you can imagine we got a lot of interesting discussion out of this one, mobile device problems, the RTM Work from 1988, Botnets, Cross-site scripting issues, and the Heartbleed bug. (Compulsory XKCD comic here.)

XKCD 1354 – Heartbleed explained concisely and accurately.
I like asking the students to go out and find things because, by presenting it to each other, we get infectious enthusiasm and we have people applying their knowledge to reinforce what we’ve learned in class.
Then, for the final hour, we sat down and discussed the course itself. The students are still free to put in anonymous reports on things they don’t feel comfortable discussing with me, but I wanted to get a feel for what we should be improving. Overall, the course has been a great success and, teaching-wise, it’s gone pretty well. We have to smooth out some administration issues on our side but we already knew that and we’re starting the planning process for the next time in the next week.
It’s really great for me to get a sense that the students both enjoyed the course and learned from the course. As we always say, engaging isn’t always effective, but in this case it appears that it has been and, so far, the results I’ve seen reflect that we’ve achieved a great deal in a short time.
Only one day left, which is mostly a final talk from me, some “thank you”s and a dinner. Then we all start our flights home.
Only two more updates for this trip to come – the final Friday and my overall reflections. Hang in there, I’m nearly done!
Teaching in Hong Kong, Day 12
Posted: July 24, 2014 Filed under: Education | Tags: alumni, AsiaBound, Central, CUHK, CUHK campus, education, exams, exchange, higher education, Hong Kong, learning, Lee Woo Sing, Lee Woo Sing College, networking, podcasts, students, teaching, xkcd Leave a commentAfter another busy Monday, we had a discussion of all of the material that had featured in the podcasts and the podcasts themselves. It was quite obvious that the students had picked up the concepts involved and had a good working and application-level understanding of what was going on. (It turned out later that the students had in fact formed a study group for some of the podcast material, watching as a group for discussion. Nice to see that can happen without prompting!) This Tuesday was an important day because it was the last day of formal ‘coursework’ in the sense of new material being discussed in the course.
We covered network security, which is one of my many areas of interest, and went through all of the many ways that horrible things can happen to nice people. I had original wanted to extend this part of the course beyond the base course content but it had quickly become apparent that jamming more into this course wasn’t going to help anyone so I covered some of the material but not in as great a depth.
A vast amount of the stuff that we cover in security is actually really well summarised at XKCD, here’s an example:

XKCD 936 – It’s ok to stop using NVdisdf&Y3 as your password.
The end of the day was a briefing session, as we were off to Macau the next day for, well, getting a sense of the culture around here and seeing how another SAR functions in its new relationship with China. I also reminded the students that passports were required and, armed with excellent local knowledge from Louis Wong at the OAL, we prepared for a Macanese adventure.
Teaching in Hong Kong, Day 11
Posted: July 24, 2014 Filed under: Education | Tags: alumni, AsiaBound, Central, Cora Chan, CUHK, CUHK campus, education, exams, exchange, higher education, Hong Kong, learning, Lee Woo Sing, Lee Woo Sing College, networking, Radio-frequency Radiation Research Laboratory, students, teaching Leave a commentI think the third week crept up on us a bit. I asked my students about it later and they said that it had really started to fly – although everyone was feeling the pressure towards the end of week 2. On the Monday morning we met late to have the short exam and then I gave the students an hour for lunch before we headed off to tour the labs that are found around CUHK itself. Another OAL host, Cora Chan, picked us up from one of the many food outlets (it’s Hong Kong, food is very serious business here) and took us to visit the Virtual Reality, Visualisation and Imaging Centre, where our students got to see research and industrial application mixing together. We saw 3D imaging displays and a really interesting example of a training device to help medical professional develop their expertise at carrying out biopsies of tumours, using computerised measurement to give a quantified indication of accuracy. Usually, a human observes you to assess your technique. In this case, computerised measurement can tell you exactly where your probe went in relation to the ultrasound and the ‘tumour’ – actually a special sponge. Had you told me that my students would be carrying out biopsy practice on this trip, I wouldn’t have believed you. We’re all learning!
We then moved on to the Radio-frequency Radiation Research Laboratory, where the team look at interesting ways to send and receive communications-band radiation, while also carrying out formal assessment work of the possible effects on humans. To do this, they have one of the most amazing looking labs in the world…
Thats the door to an anechoic chamber, designed to completely isolate anyone inside from outside electromagnetic radiation – and it’s also eerily silent because it absorbs all noise. Of course, all of us had to step inside – it’s 7m tall, which makes it one of the biggest labs of this type that there is.
It is eerily quiet in there and that giant ring, studded with sensors, is the detector array. Here’s a vertical panorama that tries to capture what the whole chamber looks like. I have included an ISO Standard Tullie for scale.
With this apparatus, and a range of things including human substitutes and replay-able mobile emissions, the team can check that an antenna is putting where it should be and not cooking anyone. Always good! The last lab on the tour was the Networked Sensors and Robotics Laboratory, where we started the tour by looking at robots designed to assist in surgery. In the picture below, the small robot to the front takes the role of a human and stabilises the patient’s internal organs for a 90-120 minute operation, where a human would typically tire. This is classic assistive robotics – they do something that we potentially have neither the strength nor patience to be able to achieve with high reliability.
In the background, yo0u can see a device that helps a surgeon stabilise the tools required for keyhole surgery – an assistant who never shakes and never tires, no matter how long it goes on. Right now these all have to be manually positioned, which still needs human involvement, but the team go to their cadaver trials very shortly and would hope to have devices like the organ assistant robot deployed into surgical theatres by 2015-2016. Good thing to keep in mind when you’re visiting hospital! We then went to see some more work being done by the students in the group on robot autonomy and position determination – taking robots to the point where, instead of careering around the room like a deranged Roomba, they learn paths properly and can follow them, on land and or on water, but without ground assisted guidance. Overall, a fantastic day for seeing research in action and, as one of the students noted, he now knew more about research at CUHK than he did about what we did back home. Hmm. Good point, we’re going to have to fix that! Thanks again to Cora and all the teams who helped us out today.
