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!

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.

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.

The Quickening of the Year Again

Posted in Biographical, History, Maynooth with tags , , , , , , , on February 3, 2025 by telescoper

Today would be the first day of teaching in Semester 2 at Maynooth University, were it not for the fact that it is a Bank Holiday in Ireland. The holiday marks Imbolc, an old Celtic festival occurring halfway between the winter solstice and vernal equinox in the Northern hemisphere. In the modern calendar the date is 1st February. In Ireland Imbolc is often referred to as a Lá Fhéile Bríde,  St Brigid’s Day, after St Brigid of Kildare, whose feast day is 1st February. In the old pagan calendar, this day is regarded as the first day of spring, as it is roughly the time when the first spring lambs are born, daffodils, etc, start to appear, and the days get noticeably longer. It corresponds to the Welsh Gŵyl Fair y Canhwyllau and is also sometimes called, rather beautifully, The Quickening of the Year. It’s a time for rebirth and renewal after the darkness of winter.

I noticed some scepticism on social media about 1st February being the first day of spring, but it makes sense to me. I feel the same way about May being the start of summer too. From living 7 years in Ireland, I’ve always found May/June the most summery months – as far as that means anything in Ireland!

In the Northern hemisphere, in astronomical terms, the solar year is defined by the two solstices (summer, around June 21st, and winter, around December 21st) and the equinoxes (spring, around March 21st, and Autumn, around September 21st). These four events divide the year into four roughly equal parts of about 13 weeks each. If you divide each of these intervals in two you divide the year into eight pieces of six and a bit weeks each. The dates midway between the astronomical events mentioned above are the cross-quarter days, of which Imbolc is one. Here they are represented on a diagram:

The timings are rough because the dates of the equinoxes and solstices vary from year to year. Imbolc is often taken to be the 2nd of February (Groundhog Day) and Samhain is sometimes taken to be October 31st, Halloween but hopefully you get the point that although the Pagan festivals have been appropriated by the Christian church, they have much older origins.

Until 2023 only three of the four cross-quarter days were associated with public holidays in Ireland; there wasn’t a holiday for Imbolc. In 2022 however, the Government decided to create a new Bank Holiday that corrected this anomaly by introducing a new St Brigid’s Day holiday on the first Monday on or after 1st February (or on Friday if 1st February falls on that day), which also happens to be the first national holiday in Ireland to be named after a woman. The first such holiday was Monday, 6th February 2023 and the second was on Monday 5th February 2024. This is the third.

But I digress.

I am glad to have today’s holiday just before teaching starts. Having completed my examination marking duties promptly I was planning to use last week to get my teaching materials ready. Unfortunately I wasn’t at all well for most of the week – though I recovered by Friday – and am way behind schedule. Fortunately, I’ve taught one of the modules (Computational Physics) many times before so not much preparation is required although it is a bigger class than I’ve had on previous occasions which means extra work in due course grading the CA components. The other module, Particle Physics is new for me at Maynooth, though I have taught it elsewhere. This also has a bigger class than I was expecting for a final-year module and my first lecture on it is tomorrow. I’m going to have to spend most of today quickening the writing of the lecture notes and preparing assignments.

P.S. Not particularly relevantly, Particle Physics is an anagram of Happier Cyclists.

Professorial Position in Observational Astrophysics or Cosmology at Maynooth University!

Posted in Maynooth, The Universe and Stuff with tags , , , , on January 30, 2025 by telescoper

You may recall that back in November 2021 we received word that Maynooth University had been awarded one of ten new senior professorial positions under the Strategic Academic Leadership Initiative (SALI). I blogged about this scheme here. The position we were awarded is a Chair (Full Professorship) in Observational Astrophysics or Cosmology.

We haven’t been able to make an appointment so far, despite trying! One of the reasons was undoubtedly that the two previous Departments of Theoretical Physics and Experimental Physics were in the throes of a merger and it was by no means certain at that time what the outcome of that process would look like in terms of the structure of the new Department. However, we now have a single Department of Physics so that at least is much clearer. So we’re trying again now.

The job announcement can be found here. It will appear on other sites shortly. Update: it is now on the Times Higher Jobs page here. The deadline is 31st March. I hope readers of this blog will help spread the news of this opportunity through their own networks.

The key rationale for these SALI positions is clear from the statement from Simon Harris, the (then) Minister responsible for Third Level education in Ireland:

“Championing equality and diversity is one of the key goals of my department. The Senior Academic Leadership Initiative (SALI) is an important initiative aimed at advancing gender equality and the representation of women at the highest levels in our higher education institutions.

We have a particular problem with gender balance among the staff in Physics in Maynooth, especially on the theoretical side, where all the permanent staff are male, and the lack of role models has a clear effect on our ability to encourage more female students to study with us.

The wider 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.

Exciting as this position is in itself, it is part of wider developments and we are expecting to advertise further job opportunities in physics and astronomy very soon! I’d be happy to be contacted by any eligible person wishing to discuss this position (or indeed the general situation in Maynooth) on an informal basis:

Thank you for your response. ✨

Maynooth University Library Cat Update

Posted in Maynooth with tags , on January 17, 2025 by telescoper

This afternoon, for the first time in a while, I encountered Maynooth University Library Cat at his customary position. Unfortunately he didn’t seem favourably disposed and when I tried to take his picture he turned his back on me. Luckily I was with a colleague who was strategically positioned to take the snap above.

Marking Progress

Posted in Biographical, Education, mathematics, Maynooth with tags , on January 14, 2025 by telescoper

I’ve been at home marking examinations almost all day and have decided to knock off until tomorrow when hopefully I can finish the job. I say almost all day because I took a break this afternoon to back to campus to collect some papers that I didn’t get yesterday because they were from students sitting the examination for various reasons in alternative venues on campus rather than the main examination room.

What I do with examination scripts is mark one question at a time rather than one script at a time. What I mean by that is that I go through every script marking all the attempts at Question 1, then I start again and do all the Questions 2, etc. I find that this is much quicker and more efficient than marking all the questions in each script then moving onto the next script. The reason for this is that I can upload into my mind the model answer for Question 1 so that it stays there while I mark dozens of attempts at it so I don’t have to keep referring to the marking scheme. Other advantages are that it’s easier to be consistent in giving partial credit when you’re doing the same question over and over again, and that also you spot what the common mistakes are more easily.

It’s a fairly monotonous job and I find my concentration starts to wander if I try to do too many in one go. Fortunately the exam papers are organized in batches (separated by elastic bands as in the photograph) so I usuallly take a break – as a sort of self-reward- after each batch to break things up. Each batch usually takes a couple of hours or so, so the breaks often end up as times to have lunch and tea. In terms of the timing it’s rather like a game of cricket, actually.

Today I corrected Question 1 in two batches before lunch, then another between lunch and tea. At that point I took a walk into town to do a few errands and then collected the remaining scripts from campus, which I have now just finished correcting. Some people will accuse me of being lazy, taking breaks like this, but I think it’s more efficient to do it this way. Trying to mark examinations for hours on end inevitably leads to more errors, so in the long run it takes longer to complete the job. Slow and steady does it.

I remember using a similar approach when I wrote my thesis many years ago. That’s a much bigger job, of course, but I found what worked for me was to plan out each chapter in terms of sections of roughly equal length, write each in turn and take a break when I’d finished it. Writing a thesis of around 200 pages may seem a daunting task, but if you split it into 1000-word chunks spread over three months or so it’s quite manageable – and you can plan to take time out for relaxtion along the way to avoid getting too burned out by the process.

Anyway, I’ve now finished all the attempts at Question 1 in this examination, including those in the extra scripts I picked up today. Question 1 consists of a set of short problems and is altogether worth 50% of the examination mark, so I’m actually abouty halfway through the marking. There three questions left, each longer than the pieces of Question 1 and worth 25% of the overall mark. Students are supposed to answer two. I’ll start on Question 2 in the morning and hopefully by this time tomorrow evening I will have marked all three, and that will be that. Until the next one…

Exam Time Again

Posted in Education, Maynooth with tags , , , on January 9, 2025 by telescoper

The January examination period starts tomorrow (10th January), so I thought I’d do a quick post on the topic of examinations. First of all let me wish the very best of luck everyone at Maynooth or elsewhere taking examinations in the next few weeks. I hope at least that the exam halls are nice and warm!

As the first examination for which I have responsibility is not until Monday 13th – unlucky for some! –  I’ll have to wait to find out how any of my students have done but let me take this opportunity to pass on a few quick tips.

  1. Try to get a good night’s sleep before the examination and arrive in plenty of time before the start. This is especially important when there’s bad weather that may disrupt travel. It is your responsibility to get to the examination on time!
  2. Read the entire paper before starting to answer any questions. In particular, make sure you are aware of any supplementary information, formulae, etc, given in the rubric or at the end.
  3. Start off by tackling the question you are most confident about answering, even if it’s not Question 1. This will help settle any nerves.
  4. Don’t rush! Students often lose marks by making careless errors. Check all your numerical results on your calculator at least twice and – PLEASE – remember to put the units!
  5. Don’t panic! You’re not expected to answer everything perfectly. A first-class mark is anything over 70%, so don’t worry if there are bits you can’t do. If you get stuck on a part of a question, don’t waste too much time on it (especially if it’s just a few marks). Just leave it and move on. You can always come back to it later.

Readers of this blog are welcome to add other tips through the comments box below!
