Terms Ending

Posted in Biographical, Education, Maynooth with tags , , , on May 26, 2023 by telescoper

So here I am, on a fine early summer evening, waiting for the train into Dublin for the last performance of the season by the National Symphony Orchestra at the National Concert Hall. I’m looking forward to it very much, as the second half is a piece I’ve never heard before. I’ll write more about it tomorrow.

There’s an end of term feeling in other ways, too. The examination period ended earlier this week, and most students have now vanished for the summer. Quite a few staff members will be marking scripts at home too. Campus has been very quiet for the last few days. The train I’m now on, the 17.10 from Maynooth to Connolly, usually very busy on a Friday, is almost empty today.

The one exception to the general lack of activity on campus happened on Wednesday when a mysterious ferret appeared on Campus. It even tried to get into the Science Building, but failed (I suppose) because it didn’t have a swipe card. It seems this critter was a family pet that had got out and went on an adventure. It was spotted at various locations around the town before being collected by its owner and returned safely home.

Artist’s impression of the ferret.

Despite that flurry of excitement, I managed to finish marking my examinations and other assessments, but the grades still need to be checked. They then have to be approved by the Departmental Exam Board in early June. They then get a final dose of scrutiny at the University Examination Board. Students will have to wait almost another month to get their results. It’s quite a slow process, but it’s right to be careful.

Days of Invigilation

Posted in Biographical, Education, Maynooth with tags , on May 22, 2023 by telescoper

I’ve now collected the scripts from my second examination – held on Saturday – and will spend the next day or two marking them and combining the exam grades with grades from class tests and projects to produce a final score.

When I went to collect the scripts for my first examination on Thursday at the end of the examination, I had to wait a little bit for them to be collated and sealed in their official packet. While that was going on I chatted to a member of staff who was putting out papers for the next examination. She was giving out about how students often move the desks when they leave, requiring them to be put back in position before the next examination.

The invigilator also expressed irritation about the system of ID cards. Each desk in the examination room has a card with a unique number on it placed in the right front corner (as seen by the student). During the examination, students are supposed to place their ID card on the desk so an invigilator can check the identity of the candidate. The student ID cards at Maynooth are about the same size as a credit card, as are the cards with the numbers. Apparently many students place their ID card directly over the number card, obscuring the number and requiring the invigilator to lift it up in order to do the crosscheck. As things go, it seems a mild transgression, but I suppose it makes an already boring job even longer for the invigilators.

Years ago, academic staff had to invigilate their own examinations. I had to do this in my first teaching job at Queen Mary and, later, at Nottingham but more recently the job has generally been done by support staff rather than academics. I moved from Nottingham to Cardiff in 2007 and don’t think I ever had to invigilate examinations there., so I haven’t done it for 16 years or so. Nowadays we are just expected to be “on call” to deal with any queries that arise in the Exam Hall by phone.

I’m not sorry that I no longer have to perform this task, as it was always one of my least favourite jobs, and not only because I don’t enjoy seeing people under stress. Initially I thought supervising an examination might allow me time to do something useful, but there always seemed to be some interruption, such as students wanting an extra answer book, or asking about some issue with the examination paper, or wanting to leave to go to the toilet, etc.

The most dramatic interruption I can remember was when a student who suffered from epilepsy had a seizure in the examination hall. Fortunately we invigilators had been briefed as to what to do in such an eventuality, namely to move the furniture so the student didn’t hurt themselves but otherwise not to intervene until they went to sleep – which usually happens after a minute or two. We were told that such an episode was unlikely as the student was taking medicine to prevent them occurring. It was quite when it actually happened, but happily the student recovered quickly but was perfectly OK afterwards. Apparently he had been so busy preparing for the examination that day he had forgotten to take his medication in the morning.

Having given up on the idea of doing some other work during an examination, I used to take a few crosswords to do. These are good for passing the time because you can solve a few clues at a time. Other things I used to do included walking around counting the number of right-handed and left-handed students, for example, though I never did any detailed statistical analysis of the results.

The primary purpose of invigilation is to prevent cheating or other misbehaviour, and I only ever saw a few examples of that – most of them involving calculators with, e.g., graph-plotting facilities which are not allowed.

Anyway, I’m glad I no longer have to invigilate examinations, and that makes me all the more grateful for the people who do. Here in Maynooth there are three examinations per day during the Examination Period, with a brief period between to put out the next set of papers, which means a long day for those who do this job. Hats off to the dedicated staff of the Exams Office at Maynooth who carry out this thankless task three times a year!

The Hate is still Out There

Posted in Biographical, LGBTQ+, Mental Health with tags , , on May 21, 2023 by telescoper

A few days ago I mentioned on this blog the case of a gay teenager in Navan being beaten up by boys from the same school; there was a news report here. Five youths were subsequently arrested but have now been released without charge. I felt a strong sense of dismay when I heard the news of their release, as the decision to let them go seemed to declare open season on homophobic violence. It may however because the assailants have to be treated as minors.

Press coverage related to this story has generally condemned the sharing on social media of a video showing the violent assault. There are quite a few people, however, including me, who think that the Gardaí would not have taken any action at all had they not been shamed into doing so by the publicity generated by the video.

Regular readers of this blog will probably understand why this case resonates with me: a similar thing happened to me way back in the 1980s. There are differences, of course. For one thing, I was rather older – in my mid-twenties rather than mid-teens. For another, the incident wasn’t reported to the police. There wasn’t any point in those days. The Brighton police at that time were notorious for dismissing complaints of gay-bashing despite the fact it was an endemic problem. People I knew who had reported such incidents usually found themselves being investigated rather than their assailants. In those days the law did not recognize homophobic offences as hate crimes. Far from it, in fact. Attacking a gay person was, if anything, considered to be a mitigating circumstance. This attitude was fuelled by a number of high-profile cases (including a number of murders) where gay-bashers had been acquitted or charged with lesser offences after claiming their victim had provoked them.

Another difference is that I didn’t go to hospital. I had a black eye, a fat lip and a lot of bruises, and had been unconscious for a time, but there didn’t seem to be any serious physical damage. The psychological effects were far from negligible, though, and I have experienced intermittent mental health problems ever since, sometimes needing to be hospitalized for psychiatric treatment. You can read about this here; a short summary is that I should have got help with this much earlier. The important thing now is that the boy who was targeted in Navan gets proper treatment and counselling. I wish him a speedy recovery.

Here’s something I wrote in 2010 after in the blog post describing my own experience of homophobic violence:

Now fast-forward about 20 years. Attitudes have definitely changed, and so has the law. Certain types of criminal offence are now officially recognized as hate crimes: the list treats sexual orientation as equivalent to race, gender, religious belief and disability in such matters. The Police are now obliged to treat these with due seriousness, and penalties for those found guilty of crimes exacerbated by homophobia are consequently more severe.

Recently, there are increasing signs of a backlash against LGBT+ people, most obviously in America but also here in Ireland. Much of this is fueled by toxic rhetoric of the Far Right who seem to want to target trans people. Social media, especially Twitter are awash with transphobic abuse and threats of violence for the reason that trans people are perceived to be easy targets. It’s up to the rest of us to make sure this strategy does not work.

I worry that the rights that the LGBT+ community has taken so long to win, could so easily be taken away. If we are complacent and pretend that everything is fixed because we have equal marriage then we will soon see those rights being eroded. LGBT+ people have to remain active and visible, show solidarity with one another, and keep pushing against all forms of discrimination, harassment and bullying wherever it happens. And the first step in doing that is to raise awareness that there is a serious problem.

I was reflecting on my own encounter with violence the other day. I try not to think about that very much, but I found myself wondering where the four guys who attacked me are now. They were about the same age as me, so will be around 60 now. Do you think the hate they expressed with their fists back in the 1980s has gone away? More importantly, do you think it reasonable that I should believe that? I don’t. The hate is still out there and will find its expression at the slightest provocation.

The reference to hate crimes in the above quote relates to the UK, of course. I was a little surprised to see that until very recently there was no legal definition of a hate crime in Ireland. Legislation has only just been introduced on this subject, with cross-party support. Among other provisions:

The new legislation will criminalise any intentional or reckless communication or behaviour that is likely to incite violence or hatred against a person or persons because they are associated with a protected characteristic. The penalty for this offence will be up to five years’ imprisonment.

The protected characteristics in the new legislation are: race; colour; nationality; religion; national or ethnic origin; descent; gender; sex characteristics; sexual orientation; and disability.

It remains to be seen how the new law works in practice.

Between Papers

Maynooth University Library Cat, photographed yesterday by Joost Slingerland.

Yesterday morning final-year students theoretical physics students sat my first examination of the session, on Advanced Electromagnetism, and tomorrow another group will take my second, on Computational Physics 1. I collected the first scripts from the Exam Hall at the end of the examination at 11.30 and have actually finished correcting them. I don’t think I’ll come in tomorrow morning though. Correcting the second batch can wait until Monday. That doesn’t mean I get a break though because I still have to complete grading the Computational Physics Projects. It does mean, however, that I’ll probably be finished with examination marking for this session by the end of next week, in good time for the Exam Boards in June.

That won’t mean that I’m finished with examination matters for the year; I’ll have four repeat examinations to grade in August. When those are done, however, I won’t have to do any further marking of examinations or anything else to do with teaching for a whole year. My sabbatical starts on 1st September.

Meanwhile, Maynooth University Library Cat, has been patrolling the area in front of the Library, which is quite busy these days with students doing last-minute revision in the study spaces there. By the end of next week the examinations will be over, most students will have departed for the summer, many staff will be at home marking scripts, and campus will be much quieter.

Maynooth University Library Cat Update

Posted in Biographical, Maynooth with tags on May 12, 2023 by telescoper

So, teaching is over at Maynooth University and the Examination Period starts today. I just checked the timetable and found that the first theoretical physics paper is not until tomorrow. Yes, we have examinations on Saturdays here! Campus is notably quieter than usual, with the only undergraduate students about being those either going to or coming from an Exam Hall. Meanwhile, Maynooth University Library Cat is strategically positioned on his wall for petting and feeding purposes, although the excitement of it all seems to have got to him and he’s fast been asleep every time I have seen him during the past week, e.g.

It’s a hard life being a cat.

Changes in the Calendar

Posted in Biographical, Cardiff, Education, Maynooth on May 7, 2023 by telescoper

As I often do on a Sunday morning, I just sat down to look at my timetable for the forthcoming week. Until Friday 12th this is “Study Week” and my Outlook calendar is noticeably less cluttered than recently because teaching ended on Friday 5th May. Although I had a lecture and a tutorial on Friday morning I did find Campus was already much quieter than usual. Many students at Maynooth University rent rooms here for only part of the week and Fridays are generally quiet because some students leave on Thursday evening if they don’t have classes on Fridays, and I suppose some that do usually have Friday classes will have had them cancelled as the lecturer had finished the syllabus. My two classes on Friday were actually for revision, actually.

At any rate the cloisters of St Patrick’s House looked rather empty on Friday as I headed for a quick lunch in Pugin Hall before the final-year project presentations in the afternoon.

Incidentally, colleagues in other departments have reported a drastic decline in lecture attendance over the last few weeks. I can’t say I’ve noticed that myself but my classes are by no means statistically representative.

I will be doing two more revision classes next week, one for Advanced Electromagnetism and one for Computational Physics. don’t know how many will attend these but it’s the students’ last chance to ask me questions before the examinations, which are on Thursday 18th May and Saturday 20th May respectively. Friday 12th May marks the start of the Examination Period – for some reason this always starts on a Friday – during which many teaching rooms are unavailable so we don’t usually do revision classes beyond Study Week.

I won’t be teaching either of these modules next academic year. In fact I won’t be teaching anything next year, as I’ll be off on sabbatical. I’ll miss the teaching and am particularly sad that I won’t see the class in my 3rd year module again, unless some of them remain for Masters or PhD studies, as they will complete their studies next year while I am away. Since I am officially on leave from 1st September 2023, my final teaching-related responsibility for this year will be marking the repeat examinations in August.

In case anyone asks, I don’t know who’ll be delivering the modules I did this year, but the handover shouldn’t be too hard as there are complete sets of notes for all of them (and plenty of problem sets).

I don’t know which modules I’ll be giving when I return either, but I hope there’s an opportunity for a bit of a reshuffle. In particular, I’ve been doing Computational Physics for six years now and maybe it’s time for a fresh pair of hands on that one. It’s not that I dislike it at all – in fact I like it – but I think there are good arguments for a refresh every now and again. I’ve always taken the view that anyone employed in a physics department should be able to teach any subject up to the 3rd year so I don’t particularly mind what happens next. At any rate it would be nice to have a go at a few different things before I retire. Who knows, I might even get to teach some astrophysics or cosmology at some point?

It’s not just about undergraduate teaching, of course. Study Week or not I still have the regular meetings with my research students, a cosmology discussion group and a Euclid telecon. But my main objective between now and the arrival of my examination scripts to mark is to finish two manuscripts that are very late. I’ve no excuse for that other than poor time management by myself.

Looking further ahead, the launch of Euclid is scheduled for the first half of July and I hope to find time to organize some sort of public event related to this. I’m also attending the Euclid Consortium annual meeting in Copenhagen at the end of June. I’ve also been invited to contribute to the UK National Astronomy Meeting, which is in early July this year, in Cardiff…

A Day of Celebration (?)

Posted in Biographical, Politics with tags , on May 6, 2023 by telescoper

The latest version of Private Eye (the cover of which is shown above) arrived in the post yesterday. I thought I’d leave it until today to read it. Apparently there’s some sort of event happening in London which appears to be causing some disruption to traffic. I’m not watching RTÉ One, the main TV channel here in Ireland, but it seems to be showing a special four hour long episode of Coronation Street. I’m surprised there’s so much interest over here in what’s going on in Poundland.

I’m told that today’s events are a celebration of “British values”, which means locking up peaceful protestors who disagree with the Establishment. On the bright side, taunting the population with a conspicuous display of wealth in the middle of a cost-of-living crisis while the rivers fill with shit and the country crumbles all around will do wonders for those campaigning for a Republic.

I already live in a Republic, of course, and today I’ll be celebrating not the Coronation but the end of teaching term. I’ll be doing a bit of gardening, watching the URC quarter finals, cooking myself a self-indulgent dinner and of course doing the Private Eye crossword. Oh, and toasting the Tories’ resounding defeat in Thursday’s local elections…

A Midweek Lecture

Posted in Biographical, Education with tags , , , , on May 3, 2023 by telescoper

It’s halfway through the last week of teaching term, and it’s been a busy day. Earlier on, I gave my final “proper” lecture of the Semester in Advanced Electromagnetism, about the reflection and transmission of electromagnetic waves at interfaces. That’s basically optics, but done in terms of the electric and magnetic fields. I have two more classes this week, on Friday, but these will be revision tutorials devoted to going through past examination questions etc. I’ve had special requests for problems involving conformal transformations and the method of images, so that should be fun!

Meanwhile, my Computational Physics class are working hard on their projects, due in on Friday. My office is opposite the lab so I’ve had a few students coming to ask for help, but mostly they are just beavering away. I hope most of them are writing up by now. I just did a quick check and nobody has submitted anything yet. I suppose that, as usual, they will all wait until the last minute!

I have a telecon coming up in a few minutes, but after that I’ll be attending this public lecture:

The speaker, Professor Clare Elwell is a physicist at University College London, where she is the Director of the Near Infrared Spectroscopy (NIRS) Group. Specifically, Prof Elwell develops non-invasive techniques to study brain function, paving the way for defining early markers of autism, developing more targeted care following brain injury, and for better understanding brain development in global health settings. Prof Elwell described her pioneering work in using invisible near infrared light to probe the human brain. Near Infrared Spectroscopy (NIRS) is a portable, wearable, low-cost brain imaging technology which can be used to study the brain in newborn babies, toddlers and adults in a range of different scenarios.

I’ll post an update when I get home after the lecture. Actually, there’s no need because the lecture was streamed and a recording is now available. The lecture starts a fairly long way in and the sound didn’t start until part-way through the introductions so I’ve cued the link to the start of the lecture itself.

It was a very interesting lecture by a very engaging speaker. The audience was smaller than I’d expected, though, with less than a hundred in the theatre. This might be because it was scheduled in the middle of the last week of teaching term, which is a very busy time of year for academic staff.

The Rising Trees

Posted in Biographical, History with tags , , , on May 2, 2023 by telescoper
The Shelbourne Hotel, viewed through the trees at the North-East corner of St Stephen’s Green

I was a bit early arriving into Dublin for the concert on Friday so decided to take a walk around St Stephen’s Green. It was a pleasant evening, and the park was quite busy with people, some sitting on the grass and some strolling around as I was. This was 28th April 2023.

The scene must have been very different 107 years ago. The Easter Rising of 1916 started on Easter Monday (24th April of that year), and ended on Saturday 29th. St Stephen’s Green was a focus of the first day of hostilities, as I blogged about here. It is obvious why the rebel forces considered this park an important location to control as it is at the junction of several main roads. On the other hand if you actually visit the location you will see a big problem, namely that the Green itself is surrounded on all sides by very tall buildings, including the swanky Shelbourne Hotel to the North.

When a contingent of about 120 members of the Citizens Army arrived in St Stephen’s Green on Easter Monday, 24th April 1916, they immediately began erecting barricades outside, and digging trenches inside, the Park. They did not, however, have the numbers needed to seize and hold the buildings around it except for the Royal College of Surgeons building to the West.

The following morning, Tuesday 25th April, the British moved two machine guns into position, one in the Shelbourne Hotel (on the 4th floor) and the other in the United Services club, along with numerous snipers. According to eyewitness accounts, almost every window in the hotel had a sniper in it. From these vantage points British soldiers could shoot down into the Park, making it impossible for the rebels to move around safely. The position inside the Green being untenable the Rebels effected an orderly (but perilous) withdrawal to the Royal College of Surgeons which they had fortified for the purpose. And that’s where they stayed until the surrender at the end of the Rising.

St Stephen’s Green is full of mature trees – there are about 750 at present – which would have been in full leaf at the time. Something I have occasionally wondered about is the extent to which the trees in late April might have afforded the rebels cover from the snipers and machine guns aimed into the park. It being the same time of year when I visited on Friday, and assuming the trees looked roughly the same as in 1916, I had a look around to see what protection they might have offered.

The answer, as you can see from the photo, is not very much…

Lá Bealtaine shona daoibh go leir!

Posted in Biographical, Education, Maynooth on May 1, 2023 by telescoper

Spring on Campus

As well as being International Workers Day, today, 1st May, is Beltane (Bealtaine in Irish) is an old Celtic festival. The month of May is called Bealtaine in Irish and May Day is called Lá Bealtaine, which is one of the so-called Cross-Quarter Days that lie (roughly) halfway between the equinoxes and solstices, in this case the Spring Equinox and the Summer Solstice. The upshot of all this is that today is a Bank Holiday, so I have the day off.

If the weather holds I shall spend a bit of time in the garden. Yesterday was quite warm but very showery. I tried three times to hang out my washing to dry in broad sunshine only to have to bring it in again when a torrential downpour arrived. Eventually I gave up.

On the corresponding days last year, the year before and the year before that I was wondering about how the pandemic would pan out. Back on May 1st 2020 I didn’t think it would last until May 2021 and back in 2021 I did not forecast that we would still have over a thousand new infections every day in May 2022.  Fortunately the pandemic seems to be dying down, though the consequences will be with us for some time.

After toady’s holiday we have four days left of teaching term at Maynooth University, then there’s a study week for the students and then the exams begin. I’ve more-or-less managed to keep on track so my remaining classes will be mainly revision. It will be quite a busy week though. Friday 5th May is the deadline for this year’s Computational Physics projects, so I’m anticipating last-minute queries all week. As well as this, and revision lectures and tutorials, I will be attending the annual Dean’s Lecture on Wednesday and attending a concert performance by members of Irish National Opera in the Aula Maxima on campus on Thursday as part of the Arts and Minds Festival.
