Lecture Recordings Again

Posted in Cardiff, Covid-19, Education, Maynooth with tags , , , , , on March 5, 2025 by telescoper

Long before the pandemic restrictions – was it really five years ago that all that started? – I posted an item about an innovation I encountered when I moved to Sussex in 2013, namely lecture capture facilities which

…allow lecturers to record videos of their own lectures which are then made available for students to view online. This is of course very beneficial for students with special learning requirements, but in the spirit of inclusive teaching I think it’s good that all students can access such material. Some faculty were apparently a little nervous that having recordings of lectures available online would result in falling attendances at lectures, but in fact the evidence indicates precisely the opposite effect. Students find the recorded version adds quite a lot of value to the “live” event by allowing them to clarify things they might not have not noted down clearly.

A few years later, when I did some teaching back in Cardiff, I discovered that lecture recording had become normal practice there too. The main difference was that Sussex had a proper policy on important matters such as who could see the recordings, and what they could be used for, which allayed some staff fears about snooping and the inhibition of academic freedon; the policy at Cardiff had not been fully developed in advance of the rollout of lecture capture, which I think was a big mistake.

Anyway, before the pandemic we didn’t really have any facilities at Maynooth University for recording lectures so it certainly wasn’t normal practice. With the onset of Covid-19 lecture recordings and live streams became the only way to carry out teaching and we lecturers made the best of what we had at home. A couple of years ago, after restrictions were lifted, I posted about a meeting between student representatives and staff in the (then) Department of Theoretical Physics during which students criticized, among other examples of inadequate teaching resources. Part of the reason for this is the drastic shortage of student accommodation which means many students have to commute long distances to campus and have difficulty doing that every day for lectures.

I – and I’m speaking personally here – wish we could offer lecture recordings as routine. Unfortunately, however, and much to my disappointment, Senior Management at Maynooth University has discouraged lecture recording as a matter of policy and has not invested in the technology required to enable it, so it is not practicable anyway.

In my view the benefits of lecture capture far outweigh the disadvantages, and we should incorporate recordings of lectures as part of our standard teaching provision, as a supplement to learning rather than to replace face-to-face sessions. Every student learns in a different way and we should therefore be doing as much as we possibly can to provide a diverse range of teaching resources so that each can find the combination that suits them best. Technology allows us to do this far better now than in the past.

Some really enjoy live in-person lecture sessions, especially the ability to interact with the lecturer and the shared experience with other students, but others don’t like them as much. Others have reasons (such as disability) for not being able to attend in-person lectures, so providing recordings can help them. Others still have difficulty attending all lectures because of a dratic shortage of student accommodation. Why not in any case provide recordings for everyone? That seems to me to be a more inclusive approach.

The problem with lecture capture in Maynooth is that we will need to improve the cameras and recording equipment in the large lecture rooms to make it possible for lectures with a significant mathematical content. The existing setups in teaching rooms do not easily allow the lecturer to record material on a whiteboard or blackboard. In Cardiff, for example, the larger rooms had more than one camera, usually one on the lectern and one on the screen or whiteboard (which has to be placed further away and therefore needs to be of higher resolution). In Maynooth we only have small low-resolution cameras in the teaching rooms. In fact I have far better facilities in my study at home – provided at my own expense – than my employer is prepared to provide on campus.

Anyway, the reason for mentioning all this is that I saw an article today in the University Times (a student newspaper based at Trinity College, Dublin). I can only infer that someone at Trinity has floated the idea of mandatory lecture recordings, because the piece argues against them even with

…established guidelines for their use, re-use, storage, and dissemination, and a ban of their use during industrial action.

I think a properly negotiated agreement with the Trade Union representing staff (e.g. IFUT, of which I am a member) covering these points would allow me to accept mandatory lecture recordings. Worries about covert monitoring or unauthorized dissemination on social media would hopefully be assuaged by such an agreement. A particular issue in the UK, given the current meltdown of its higher education sector, Senior Management may sack lecturers to save money but keep using their recordings. That would be unconscionable, but that doesn’t mean it won’t be tried.

Term goes on…

Here we are, about to start the fifth week of the Spring semester at Maynooth University. Teaching isn’t going too badly, but I have come to realize that I have a lot of continuous assessment marking to do – classs tests and mini-projects for Computational Physics and assignments for Particle Physics. The numbers of students involved are 32 in the first case and 23 in the second, but I have to do all the corrections myself. Ho hum. Still, I’m enjoying teaching particle physics again after a gap of 15 years or so so I can’t complain about that.

Last week saw some important achievements by research students. Two students in the Department of Physics – one of them supervised by me – submitted their PhD theses last week. Nominations of examiners have to be approved by Faculty and Academic Council but that should be a formality and we then have the viva voce examinations, so the process is not over yet, but the submission of a thesis is a landmark in itself and is to be celebrated.

Something less worthy of celebration is the ongoing chaos at Maynooth over funding for future research students. You may recall that I posted about the terrible decision by the Management of Maynooth University to scrap the John and Pat Hume Doctoral Scholarships and followed this up with another post suggesting the decision might be reversed and another pointing out that it hadn’t been. The Hume scheme has been paused for a “review”. That review was actually completed in January. It is now March and academic staff have still had no word about the status of the Hume Scholarships. Someone is stalling.

I have received a number of enquiries in recent weeks from prospective students about when applications would open as I’m sure is also the case for several of my colleagues. It has been very depressing to have to reply saying that I have no idea. As far as I know the scheme is suspended indefinitely. It’s now effectively too late for this year anyway, as most prospective students will already have lined up offers elsewhere. Only students not able to secure a place elsewhere will be available to apply if and when the scheme does open.

The timing of this is especially sad for the new Department of Physics. Our final-year Theoretical Physics class sizes are larger than ever but the Maynooth is sending them a very clear signal that it doesn’t want any of them to stay here for their PhDs.

The Universe Keeper

Interested in learning a little bit about the ideas behind string theory? Here’s a short video that tries to explain the basics in a thought-provoking way. It features three main characters: The Universe Keeper Renata, inspired by Russian-American physicist Renata Kallosh, the quizzical Wolfie, inspired by the Austrian Nobel laureate Wolfgang Pauli, and the inquisitive Albie, inspired by Albert Einstein.

See what you make of it…

(One of the creators of this video is my PhD student Kay Lehnert, who has just given a departmental seminar in which he mentioned the video.)

Particle Physics Masterclass at Maynooth

Posted in Education, Maynooth, The Universe and Stuff with tags , , on February 23, 2025 by telescoper

Last week’s announcement about Ireland joining CERN reminded me that I should have advertised the annual Particle Physics Masterclass at Maynooth University long before now, not least because I’m actually teaching particle physics this year. My only excuse is that I’m old and forgetful. Anyway, better late than never; there’s still almost a week until the registration closes.

Since 2012 the Department of Theoretical Physics hosted the International Particle Physics Masterclasses for secondary school students each spring (except for 2020 when it was cancelled due to Covid-19 restrictions).  Now the Department of Theoretical Physics is no more, having been incorporated last year into the Department of Physics, but the Particle Physics Masterclasses continue; the next event will be on Tuesday 18 March 2025.

These Masterclasses give secondary school students the opportunity to discover the world of quarks and leptons for themselves, by performing measurements on real data from CERN, meeting active particle physics researchers and linking up with like-minded students from other countries.  We will join thousands of other secondary school students at more than 100 universities and laboratories around Europe and worldwide in a programme stretching over four weeks.

Physics at the most fundamental level – the smallest and most basic building blocks of matter – is an exotic world.  But a few introductory talks and working with data from CERN will give the students insight into the fundamental particles of matter and the forces between them, as well as what went on during the Big Bang.

In the morning the students are introduced to particle physics, experiments and detectors in lectures given by active particle physics researchers.  After an early lunch, they work on their own with data from the ALICE detector at CERN. Afterwards they participate in a video conference with students from other countries and moderators at CERN, where they discuss and compare their results.  For more information on the masterclasses, see the International Masterclasses web site.

You can find more information about the event here and you can register here. Hurry up though as the deadline for registration is the end of this month, i.e. this Friday, February 28th!

Geometric and General Relativistic Techniques for Non-relativistic Quantum Systems

Posted in Maynooth, The Universe and Stuff with tags , , on February 19, 2025 by telescoper

The other day I mentioned the forthcoming graduation of a Maynooth PhD student. His name is Aonghus Hunter-McCabe and his main supervisor was Maynooth colleague Brian Dolan, and I just took over when Brian retired to see Aognhus through the latter stages. Anyway, asof yesterday, his thesis is available on arXiv (on hep-th) as well as on the Maynooth University Research Archive Library (MURA) here, so as it is all in the public domain I thought I would advertise it here, as I think it is very good indeed (though I would say that!) and also in case anyone out there is looking to employ a PDRA in a related area…

The abstract is:

This thesis explores the application of differential geometric and general relativistic techniques to deepen our understanding of quantum mechanical systems. We focus on three systems, employing these mathematical frameworks to uncover subtle features within each. First, we examine Unruh radiation in the context of an accelerated two-state atom, determining transition frequencies for a variety of accelerated trajectories via first-order perturbation theory. For harmonic motion of the atom in a vacuum, we derive transition rates with potential experimental realizations. Next, we investigate the quantum Hall effect in a spherical geometry using the Dirac operator for non-interacting fermions in a background magnetic field generated by a Wu-Yang monopole. The Atiyah-Singer index theorem constrains the degeneracy of the ground state, and the fractional quantum Hall effect is studied using the composite fermion model, where Dirac strings associated with the monopole field supply the statistical gauge field vortices. A unique, gapped ground state emerges, yielding fractions of the form ν=1/(2⁢k+1) for large particle numbers. Finally, we examine the AdS/CMT correspondence through a bulk fermionic field in an RN-AdS4 background (with a U(1) gauge field), dual to a boundary fermionic operator. Spherical and planar event horizon geometries are discussed, with the temperature of the RN black hole identified with that of the dual system on the boundary. By numerically solving for the spectral functions of the dual theory, for a spherical event horizon at zero temperature, we identify a shift in the Fermi surface from that which arises in the planar case. Preliminary evidence of a phase transition emerges upon examining these spectral functions, again for the spherical horizon, at non-zero temperature.

Two Weeks into Term…

Posted in Biographical, Education, Maynooth with tags , on February 17, 2025 by telescoper

I thought that this semester would have had an easier start than the last because I am teaching only one new module (and one familiar one) instead of the two new modules I had last semester. Unfortunately I wasn’t very well before the start of this one and have been struggling to recover so this term hasn’t been easy at all and I’ve had a lot to catch up. At least I’ve managed to stay on top of the lectures and lab sessions and everything so far has gone relatively smoothly. I have to admit though that only two weeks in, I already feel extremely tired. I went to bed at 9pm last night and slept straight through to my alarm at 7am. I’m getting old.

Last week we had our Examination Board meeting for Semester 1 in the Department of Physics. I also attended the Examination Board for the Department of Engineering because I was teaching an Engineering Mathematics module last semester. The students in both Departments should receive their provisional examination results this week, although there have been some gremlins in the campus systems which may lead to a delay in the marks being released.

Semester 2 is a bit more complex than Semester 1 because of a number of interruptions for holidays, etc. The first Monday of this term was actually a holiday, but I don’t actually have lectures on Mondays this term so that didn’t matter, nor will Monday 5th May which is also a holiday. I do, however, have a Particle Physics lecture on Fridays so will miss one on because of the national holiday on April 18th for Good Friday and will have to plan accordingly. The following week (Mon-Fri, starting on 21st April) is the Easter Break, and the week from 17th to 21st March is Study Week (starting with the St Patrick’s Day national holiday on Monday 17th). Although the number of teaching weeks is the same as Semester 1, they are spread out over a longer period with two gaps instead of one. One break is coming up about a month from now, and then another a month after that. This schedule is rather kind to those of us Oldies who tire easily!

Although I’ve kept up with the teaching preparation reasonably well, I have let other things slip. In particular, I have a graduate student getting ready to submit their PhD thesis ahead of an imminent deadline. I promised to read it and supply suggestions/corrections which I have yet to. That’s right at the top of my list for this week.

Talking of PhD students, my first ever official PhD student at Maynooth has already already passed his viva voce examination – about a year ago actually – but owing to bureaucratic delays he won’t graduate until this year, at a conferring ceremony in the March study week mentioned above.

Professorial Position in Observational Astrophysics or Cosmology at Maynooth University!

Posted in Maynooth, The Universe and Stuff with tags , , , , on February 12, 2025 by telescoper

It’s been a couple of weeks since I announced a job opportunity in the form of Professorial position in Observational Astrophysics or Cosmology at Maynooth University. After a short bureaucratic delay the announcement has just appeared on the AAS Jobs Register here, which gives me an excuse to post about the poistion again. The deadline is 31st March 2025. I hope readers of this blog will help spread the news of this opportunity through their own networks.

The strategic case for this Chair revolves around broader developments in the area of astrophysics and cosmology at Maynooth. Currently there are two groups active in research in these areas, one in the former Department of Experimental Physics (which is largely focussed on astronomical instrumentation) and the other, in the former Department of Theoretical Physics, which is theoretical and computational. We want to promote closer collaboration between these research strands. The idea with the new position is that the holder will nucleate and lead a research programme in the area between these existing groups as well as getting involved in outreach and public engagement.

It is intended that the position to appeal not only to people undertaking observational programmes using ground-based facilities (e.g. those provided by ESO, which Ireland recently joined), or those exploiting data from space-based experiments, such as Euclid, as well as people working on multi-messenger astrophysics, gravitational waves, and so on.

P. S. For those of you reading this from outside Ireland the job includes a proper public service pension, a defined benefit scheme way better than the UK’s USS.

Maynooth University Library Cat System Update

Posted in Biographical, Maynooth with tags on February 10, 2025 by telescoper

I forgot to mention that last week I had to run the first Computational Physics laboratory session of the year. When I was setting things up before the session I saw that we had a different version of the operating system on our cluster from what we had two years ago when I last taught this module. More importantly, all the student accounts had been provided with this desktop background image…

A Campus Incident

Posted in Biographical, Maynooth, Mental Health with tags , , on February 5, 2025 by telescoper

I received an alarming “All Staff” email yesterday from Maynooth University that contained the following:

 I am writing to inform you of a serious incident on South Campus last night (Monday, February 3rd). An individual entered the campus and engaged in unprovoked physical altercations against a small group of students and staff. Based on our current understanding, this appears to be an isolated incident. The suspect has been arrested, and the Gardaí are investigating.  

That was all it said about the nature of the incident which took place on Monday evening at about 18.50. The University was closed all day Monday for the Bank Holiday and I knew nothing about it until I received the email. I found the lack of information very concerning. More details were available in the local news (e.g. here), however, including the fact that a person had been arrested and charged and was due to appear in the District Court at Naas this morning. The fact that the matter was in front of the courts was no doubt the reason no further information was disclosed to staff.

After the hearing, the case was covered in the usual court reporting (e.g. here) which reveals that the victim of the serious assault was a priest who needed treatment in hospital; three students were also attacked and some property damaged. The accused was charged with four counts of assault causing harm, two counts of criminal damage and one count of burglary; he has a history of psychiatric problems and was remanded without bail for evaluation in the medical wing of Cloverhill prison. It seems the individual concerned may have experienced some kind of psychotic episode.

All we can hope is that the victims recover speedily from their injuries and the shock caused by such an episode. I hope they all receive counselling. This looks like very much like a failure of Ireland’s mental health system to take proper care of the person responsible. In the long term I hope that he gets proper treatment. That way at least some good might come out of this awful incident.

Back to Teaching

Posted in Biographical, Education, Maynooth, The Universe and Stuff with tags , , , on February 4, 2025 by telescoper

After yesterday’s holiday it was back to teaching full-time this morning with the first lecture of my module on Particle Physics. I just about managed to get everything ready in time for the teaching session at 1pm which, because it was an introductory lecture with lots of pictures, I decided to do via powerpoint rather than my usual chalk-and-talk. That didn’t get off to a very good start because the podium PC in my room had decided to do a Windows update just before I started and I had to wait for that to finish before I could show my slides. I suppose that happened because this was the first day of teaching after a lengthy break so nobody had used the room recently.

Most of the lecture was devoted to introducing natural units, which I intend to use throughout the module, like I have on previous occasions I have taught this sort of material for reasons I explained here. The last time I taught particle physics was some 15 years ago, so I had to update some things, especially the picture of the components of the standard model to include the Higgs. After extensive research (by which I mean looking at wikipedia) I found the above; the Higgs is on the right. Unfortunately the particle masses – which reveal themselves if you click on the image above – are not given in natural units, but have pesky factors of c-squared in them. You can’t have everything.

The bit I’m looking forward to most is doing the Dirac Equation which, years ago when I was at Sussex, was once the subject of a cake:

That particular cake was a lemon drizzle cake which unfortunately is not one of the flavours represented in the standard model.
