Lectures’ End

Posted in Biographical, Education, Maynooth, The Universe and Stuff with tags , , on May 8, 2026 by telescoper

At last we’ve made it to the end of term. This morning I delivered my last particle physics lecture. Given that it is the last day of the semester I was half-expecting no students would turn up, but in the end I had about 60% attendance. At the end of my lecture there was even a smattering of applause, which I interpreted as meaning that the students were happy that I’d finished.

I thought I would end this module with some topics that I didn’t have time to cover in any detail, but thought the students should know at least something about. These loose ends included:

  • Renormalization
  • Grand Unified Theories (GUTS)
  • Supersymmetry (SUSY)
  • Particle candidates for Dark Matter
  • Baryogenesis

I only had time for a superficial treatment of these topics, but felt the class should at least hear the words. There are some very good unanswered research questions under those headings, which I think is an appropriate way to end a final-year module, given that at least some of the class are intending to carry on to further study in physics.

This afternoon we had a colloquium by our PhD student John Ibrahim on the subject of the “Quark‑Gluon Vertex and Confinement of Quarks”. It was a nice talk but it struck me how big the gap was between what I’d been teaching at undergraduate level and the standard that a PhD student has to reach.

Today was also the deadline for Computational Physics projects. I’ll be grading them next week. Even then the term won’t quite be over – there is the small matter of exam marking to be done – but at least I’ve got no more formal teaching to do until September.

Last night on the way home I decided to buy a nice bottle of white wine and put it in the fridge so I could drink it in celebration of the end of term when I get home, with a nice fish supper.

Last Chance Lab

Posted in Biographical, Education, Maynooth with tags , , on May 7, 2026 by telescoper

Today is the penultimate day of teaching in the Spring Semester at Maynooth University and I’m here in the Computer Lab for the last time. This afternoon’s session is just a drop-in consultation session for Computational Physics students doing their projects and although it has been busier than previous weeks it has not exactly been a hive of activity. The deadline for project submissions is tomorrow afternoon, so I was expecting a bit of a rush at this session, which is the last of its type, and also at my office hour this morning. I did have one student attend this morning, and a couple of others this afternoon, but other than for them it has been quiet.

On the other hand, over a day before the deadline, three students have already submitted their project reports and code. I’m impressed with that, but also a little surprised. I’ve come to expect just-in-time delivery for such things.

Yesterday I did my last particle physics tutorial of the year and followed that immediately afterwards I attended a long session of final-year project talks, from 3pm to just after 6pm. It is obvious that some students find these presentations a bit of an ordeal but it is important to learn how to present your work so such things are part of the rite of passage. It is good for staff to get an overview of the all projects being done in the Department too.

In previous years the final project presentations for students in the Departments of Theoretical Physics and Experimental Physics were done separately, the former having a somewhat smaller audience than the latter. The two previous Departments having merged into a single Department of Physics, this time round we had all the talks together (though spread over two days, yesterday and the Wednesday before). I think the combined sessions worked quite well and we will probably do it this way next year.

After the session of talks there was a small drinks party in the foyer of the Science Building. That was a nice occasion, and it struck me that it would have been the last time this group of students would all meet together until their graduation. Tomorrow I do my last particle physics lecture and it will be the last time I see quite a few of the students in that class until graduation too. They’ve been a nice group to work with, very engaged and easy to interact with. It is a great pleasure to be teaching students who are eager to learn . That’s the aspect of academic life I’ll miss the most when I retire.

Maynooth University Library Cat Update

Posted in Maynooth with tags , , , on May 6, 2026 by telescoper

This lunchtime I saw Maynooth University Library Cat in a more pastoral setting than usual. Having just had his lunch, it being sunny, and the area around the Library being somewhat busy, I reckon he had it in mind to have a quiet snooze in the shade of the trees.

Ten Signs of a Toxic University

Posted in Education, Maynooth with tags , on May 3, 2026 by telescoper

I saw this on LinkedIn the other day, and thought I should share it here:

If you work in a University, what’s its score? I was thinking we could make a League Table, but so many institutions would get 10/10 that would be pointless.

Thoughts on 1st May

Posted in Biographical, Education, Maynooth with tags , , , on May 1, 2026 by telescoper

Today, 1st May, Beltane (Bealtaine in Irish), is an old Celtic festival that marks the mid-point between the Spring Equinox and the Summer Solstice. It’s one of the so-called Cross-Quarter Days that lie exactly halfway between the equinoxes and solstices. These ancient festivals have been moved so that they take place earlier in the modern calendar than the astronomical events that represent their origin: the halfway point between the Spring Equinox and Summer Solstice is actually next week. Anyway, “May Day”, Lá Bealtaine in Irish, is today – the name Bealtaine applies to the whole month of May.

In Ireland the Bank Holiday associated with Bealtaine is on Monday 4th May, so another long weekend beckons.

Workwise, after today we will have completed the penultimate teaching week of Semester 2 so after Monday’s Bank Holiday we will have just four official days of teaching left, before a Study Week and the start of examinations. Yesterday I correctedthe last of my Computational Physics class tests so I am up to date with the continuous assessment and feedback of both my modules. I now have a week before the Computational Physics projects are submitted, and another week before the exam period starts.On Wednesday last we had project presentations for about half of the final year class; the other half do their things next Wednesday.

Now, I have a particle physics lecture to give – the antepenultimate one of the semester – after which I’ll be launching myself into the long weekend.

Lá Bealtaine shona daoibh go leir!

Two Weeks To Go…

Posted in Biographical, Education, Maynooth with tags , , , on April 27, 2026 by telescoper

There are just two weeks of teaching left in the Spring Semester at Maynooth University. Actually slightly less than that because next Monday (May 4th) is another bank holiday. That day doesn’t make any difference to my own teaching, however, as I have no teaching sessions on Mondays anyway.

As I mentioned last week, the formal teaching part of one of my modules (Computational Physics) is already over and the students are now – or should be – busy doing mini-projects.

My other module, Particle Physics, has four remaining lectures. That means that I’m on schedule, despite missing one lecture on Good Friday. The very last lecture for this module is on the last day of term, May 8th, so I don’t know how many students will be there. Come to think of it, because this is a final-year module, it may actually be the last lecture of all at Maynooth for some students…

The end of teaching does not mean the end of the term, however. We have a short “break” and then, on May 15th, the examinations start. In the break I’ll have to mark a stack of Computational Physics projects. That’s always quite hard work as I have to run the codes and check the results as well as read and grade the written reports.

This week and next we also have the final presentations for project students. That will take up two whole full afternoons (this Wednesday and next Wednesday). There’s usually a bit of a do after these to give the students a send-off, as these are projects done by the graduating class. I have been supervising two students this year, plus an MSc student (though the latter will not finish until August).

People sometimes ask me why we have such heavy teaching loads at Maynooth University. Four modules a year – other staff do five (as I did a few years ago when was also Head of Department) – plus projects is far more than one would expect of a “research-led” University outside Ireland. Part of the reason is what I mentioned yesterday – that the University (along with most others) spends far too much of its income on Management salaries and projects that have nothing to do with research or teaching. Other than that I can’t comment. According to this document, Maynooth University has committed to

Introduce a University Workload Allocation Model (WAM) enhancing transparent processes and procedures in the allocation of work.

If there is such a model, it is news to me…

P.S. There’s an even older document here (dated 2014) that says:

The University is committed to ensuring that the allocation of work is reasonable and fair across and within academic units. It is also required to exercise oversight of the implementation of academic workload management. In support of this, the Head of Department / School / Institute will monitor and record workload allocations and will provide to the university, via the Faculty Dean, an annual report on the procedure and model used to allocate workloads, and also an anonymised summary of the average and range of workload distributions between teaching, research and service among all academic staff in the Department/School/Institute.

The design and implementation of workload allocation models will be undertaken by Departments/Schools/Institutes in accordance with the general principles outlined above.

Will it? When?

The Sharp End of Term

Posted in Biographical, Education, Maynooth with tags , , , on April 23, 2026 by telescoper

So here I am, sitting in the (empty) Physics Computer Lab. The formal Computational Physics lab sessions are over, but I’m on duty to provide help the students with their project work, which will take up the remaining two-and-a-bit weeks of term. It’s a lovely day outside which explains why there are very few people in the lab, and none of them have asked for help so I’ve been busy getting on with some work. Past experience with these sessions suggests that they’ll all come just before the project deadline, which is May 8th.

Up until last week I had a Computational Physics lecture at 9am on Thursdays, but the last one of those happened last Thursday. It was nice to have a more leisurely start this morning. I did think I might get a haircut on the way to work but when I passed my usual barber’s I saw it was full of people waiting their turn so I walked on. It seems that the good weather gave quite a few people the same urge to have shorter hair.

Yesterday was the last Class Test for my other class, Particle Physics, and I’ve taken the opportunity to correct all the scripts for that. I even had time to type up the solutions all neatly and tidily in Latex (including doing Feynman diagrams, which is fun).The end of that job means no more grading for that module until the main examination, which is about a month away. I do however, have lectures and tutorials still to do, including two at 9am on Tuesdays.

The finest weather is usually reserved for the exam period, of course, to maximize the annoyance of students. In my memory all my undergraduate examinations took place in very fine weather, with the exception of my Physics practical the night before which there was an enormous thunderstorm. Come to think of it, that could well have been a portent that warned me off experiments and made me become a theorist.

Maynooth University Library Cat Update

Posted in Maynooth with tags , , , on April 22, 2026 by telescoper

This week at Maynooth University numerous parties of schoolkids have been, and are being, shown around the campus. Naturally an important stop on this tour is the abode of Séamus the Library Cat. The weather has been nice this week so far, as it was today, so said feline has generally been out and about and making himself available to be admired. On my way to lunch I managed to bypass a large coach party of schoolgirls and reach the cat’s spot ahead of them. I found Séamus giving himself a good wash and brush-up in anticipation of the arrival of the visitors.

Back for the Last Four Weeks…

Posted in Biographical, Education, Maynooth with tags , , , on April 13, 2026 by telescoper

So the Easter break is over and I was back to campus today armed with a very long to-do list. I’m pleased to say I’ve ticked all the items off except the last, which was to prepare my lecture for 9am tomorrow. I’ll do that after supper.

I was very tired this morning after doing a bit of gallivanting for a couple of days. Am I too old to be carrying on like that? Yes. Do I intend to stop? No. Although I had a lot to do I didn’t have any lectures or tutorials so I was able to knuckle down and get on with things, interrupted only by an obligatory telecon.

We have four weeks left until the end of lectures for Semester 2. To be precise it’s four weeks minus one Bank Holiday (on Monday 4th May) which makes it 3.8 (working) weeks, but I don’t have lectures on Mondays so this isn’t very relevant to me. My Particle Physics module will continue in the same vein until the end of teaching but Computational Physics changes after this week, with lectures and formal lab sessions ending allowing the students time to do their mini-projects (which they have already started). They will still have access to the labs and be able to consult the demonstrators for help on their projects, though they can work at home (or somewhere else) instead if they prefer.

Other signs of the approaching end of term is that the May Examination timetable has been published, the required papers are being printed, schedules of student presentations are being circulated, and arrangements being made to mark projects.

When teaching is over for the academic year , and before exam marking starts, assuming a whole day of decent weather arrives, I plan to walk from Maynooth into Dublin along the Royal Canal. That’s a distance of 27 km. I do intend to walk the length of the National Famine Way later this year, but I was convinced to do one stage first to see if my knees can take it. The final leg of the Famine Way is from Maynooth to Dublin, which is convenient because if I’m forced to give up I can easily get the bus or train home, as I can if I reach the end.

Now for a quick supper, write my lecture for tomorrow morning, and have an early night!

Ahead of a Four-Day Week…

Posted in Artificial Intelligence, Biographical, Education, mathematics, Maynooth with tags , , , , , , on March 29, 2026 by telescoper

It’s Sunday 29th March – Palm Sunday in fact – and Friday 3rd April is Good Friday, which is followed by a break of a week for Easter, so I’ve been looking at what I have to do in the four days between Monday and Thursday.

On Tuesday afternoon part of my 3rd Year Computational Physics class will be doing a supervised test in the computer lab. I (foolishly) promised to ensure they would get their grades before Easter, so I’m going to have to mark them straight away. This is a larger group than usual because some students who would normally be in the lab on Thursdays swtiched to Tuesday so they could go on a trip to Armagh. Anyway, this is the third lab test and at least I have graded the first two tests for all groups in time for the arrival of the new ones.

There will be one more of these lab tests after the Easter break but after that the students will be working full-time for 3 weeks or so on mini-projects. That is the part they usually enjoy most and I’m very happy to see that some have already started work.

Then, on Wednesday I have the second class test for my 4th year Particle Physics module. This is the second such test, and it will be held during a tutorial session. This is a pen-and-paper test rather than a coding test to be done in the lab. For such tests I allow students to bring whatever they like on paper but phones, laptops and tablets are banned. This is the easiest way I could think of to avoid students using AI to solve the problems. In previous years I gave take-home assignments for this module, and I still hand out exercise sheets to be gone over in tutorials, but these are for formative purposes only. The summative assessments are the class tests. There will be three of those, which means they will have to endure one more after Easter. In a normal week I would have a Particle lecture on Friday, but that won’t happen because it’s Good Friday and my lectures apparently aren’t good enough to happen on that day.

As well as the Computational Physics lab test and the Particle Physics class test, next I have two lectures, both at 9am – one on Tuesday and one on Thursday – and another lab session on Thursday which is not a test, but a practical session about solving ODEs.

Then it will be the Easter Break. After that, according to my calculations, there will be four more teaching weeks before the examination period. The last day of teaching is May 8th. Between that and the examinations there is a gap of a week during which I will have to mark all the completed Computational Physics project reports, as well as giving some revision classes if there is demand for them.
