Term goes on…

Posted in Biographical, Education, Maynooth with tags , , , , , on March 2, 2025 by telescoper

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 University of Edinburgh in Crisis

Posted in Education, Finance with tags , , , , on February 26, 2025 by telescoper

It seems that financial emergencies are spreading around the United Kingdom like a contagion. About a month ago I posted about the crisis at Cardiff University, but now there’s a bombshell about the University of Edinburgh which, according to the Times Higher is planning to make cuts of around £140 million in recurrent expenditure, about 10% of its annual operating budget. This level of cuts is greater than those previously listed at other universities, including Cardiff, the largest of which are measured in tens of millions. The piece goes on to explain that target can’t be reached by voluntary redundancies, which presumably means compulsory redundancies are looming.

I don’t know which particular academic units are under threat, but I’m sure this episode is causing a great deal of stress to a great many people. The only advice I can offer to anyone at Edinburgh worrying about the future is, if they haven’t done so already, to JOIN A UNION!

Talking of which, the University of Edinburgh UCU has pointed out that the University revealed a budget surplus last year and has huge reserves measured in the billions. It accuses managers of manufacturing a crisis in order to cut staff and bring about even more centralisation – thus achieving an even greater level of corporate control over teaching and research activities. The subordination of academia to management is the aim. I don’t doubt that university managers around the world believe that teaching will be largely done by AI anyway which will allow even more lecturing staff to be cut.

I believe that universities need less centralisation not more. The Principal of the University of Edinburgh, Peter Mathieson, is quoted in the Times Higher piece as saying:

We can no longer afford to run duplicative services across the university, often with inconsistent practices which create inefficiencies, increase staff workload and impact our student experience..

This is fair enough, but it is quite wrong to assume that greater centralisation is the solution. In my experience it is “The Centre” that creates inefficiencies, increases staff workload and impacts student experience. That is because it knows far less than Schools and Departments about what is needed to achieve their academic objectives. Universities need a flatter and more responsive structure, not the ever-increasing management bloat that has been imposed on them for decades and which is now causing them to capsize.

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.

Introducing the Clartiverse™

Posted in Education, mathematics with tags , , , , on February 16, 2025 by telescoper

The recent decision by Maynooth University to appoint a Ranking Strategy and Insights Officer in an attempt to raise the University’s position in university league tables has inspired me to create a new spinout company to provide a service for higher education institutions who want to improve their standing in rankings while avoiding the expense and complication of actually improving the institution or indeed while continuing to pursue policies that drive performance in the opposite direction.

I have decided to name my new company CLARTIVERT™ and the extensive suite of services we will provide is called the Clartiverse™.

The idea of CLARTIVERT™ is to produce, in return for a modest payment equivalent to the salary cost of a Ranking Strategy and Insights Officer, a bespoke league table that guarantees a specified position for any given institution. This can be either your own institution whose position you would like to raise or some competitor institution that you wish to lower. We then promote the league table thus constructed in the world’s media (who seem to like this sort of thing).

The idea behind this company is that the existing purveyors of rankings deliberately manufacture artificial “churn” in the league tables by changing their weighting model every year. Why not take this process to its logical conclusion? Our not-at-all dodgy software works by including so many metrics that an appropriate combination can always be chosen to propel any institution to the top (or bottom). We then produce We achieve all this by deplying a highly sophisticated branch of mathematics called Linear Algebra which we dress up in the fancy terms “Machine Learning” and  “Artificial Intelligence” to impress potential buyers.

To begin we will concentrate on research assessment. This is, of course, covered by existing league tables but our approach is radically different. We will desploy a vastly expanded set of metrics, many of which are currently unused. For example, on top of the usual bibliometric indicators like citation counts and numbers of published papers, we add number of authors, number of authors whose names start with a given letter of the alphabet, letter frequencies occuring in published texts, etc. We adopt a similar approach to other indicators, such as number of academic staff, number of PhD students, number of research managers, initial letters of names of people in these different categories, distribution of salaries for each, and so on.

As well as these quantities themselves we calculate mathematical functions of them, including polynomials, exponentials, logarithms and trigonometricfunctions; sine and cosine have proved very useful in early testing. All these indicators are combined in various ways: not only added, but also subtracted, multiplied, and/or divided until a weighted combination can be found that places your institution ahead of all the others.

In future we will roll out additional elements of the Clartiverse™ to cover other aspects of higher education including not only teaching and student satisfaction but also more important things such as commercialisation and financial impropriety.

P.S. The name Clartiver is derived from the word clart and is not to be confused with that of any other companies providing similar but less impressive services.

Book of the Week

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.

Cardiff University in Crisis

Posted in Cardiff, Education with tags , , on January 28, 2025 by telescoper

I saw in the news today that Cardiff University has announced a series of mergers, closures and widepsread job cuts in order to deal with a financial deficit. If I understand the announcement correctly, the intention is to terminate the equivalent of 400 full-time academic posts, which is over 10% of the academic staff complement. No doubt there will also be job losses among the important professional services and support staff. There is plenty of doubt, however, as to whether they will extend to members of the Senior Management Team who made today’s announcement and who should really be the ones held to account.

Cardiff is by no means the only UK university being decimated in this way. It is just the latest in a long list. The crisis in UK higher education has been brewing since Brexit, and the subsequent reduction in overseas students needed to balance the books in the absence of significant ncreases in tuition fees for UK students. A burst of inflation post-Covid and, more recently, increased National Insurance contributions have taken many institutions to the brink of solvency. That’s the official line. You can add, unofficially, poor decision-making at senior management level, in many cases pursuing expensive and over-ambitious vanity projects that have ultimately proved unaffordable but impossible to cancel.

One has to remember that when university managers make decisions on closing down units, it’s not often on the basis that those units are losing money. For a start, universities operate according to complicated and arbitrary financial models small adjustments to which can easily move a department from black to red or vice versa. Moreover, over half the income of a university is not spent on the front-line activities of teaching and research: a huge slice is absorbed by the central administration to fund “strategic” investments (i.e. risky projects) and of course to pay vast salaries to the VC, PVCs and other assorted cronies. Departments therefore tend to be judged not on whether they can cover their own costs but whether they return a surplus to The Centre.

(Incidentally, while the UK Higher Education sector is in turmoil, there is no sign of vice-chancellor pay packages being cut. Quite the opposite, in fact.)

I’d be the first to admit that running a large university is a difficult job. Even in the lower levels of management as Head of School at Sussex, I agonized over many decisions. During that time I came to the conclusion that being a successful manager of something is very stressful if you actually care about it. This is why so many of the people who prosper in senior university management circles are not people who care at all about what makes a university what it is. They just see everything as a sterile combination of metrics and spreadsheets and boxes to be ticked. This, not the funding shortfall per se, is why universities are experiencing an “existential crisis”.

Anyway, among the specific proposals at Cardiff are the closures of courses and whole Departments in Ancient History, Modern Languages, Music, Nursing and Religion & Theology. Job cuts (or, as the announcement puts it, “reductions in staff FTE”) will affect (among others) the Schools of Biosciences, Chemistry, Computer Sciences, Engineering, Mathematics, and Medicine. The list of Schools to face job losses look to me to be mainly those who had relied strongly on overseas students as a source of revenue, a source which must have dried up.

Another proposal (one of four mergers of Schools) involves the creation of a new School of Natural Sciences formed by merging Chemistry, Earth Sciences and “Physics”. The latter should be “Physics & Astronomy“, not “Physics”. I hope that carelessness is not typical of the forthcoming process. Physics & Astronomy is not earmarked for losses of academic jobs, but the merger is almost certainly intended to allow cuts in support staff. As per the above paragraph, Chemistry staff will be cut, so the new School of Natural Sciences will not be off to a happy start.

I worked at Cardiff University for many years, and am in regular touch with a number of friends and former colleagues still there, so this news is very distressing. All I can do is offer a message of solidarity and encourage everyone who is not in a Union to join immediately! I have a terrible feeling that today’s announcement is only the start.

The Dangers of AI in Science Education

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

I’m taking the liberty of reblogging this post from an experienced university teacher of chemistry and physics outlining some of the dangers posed by the encroachment of Artificial Intelligence into science education. It’s quite a long piece, but well worth reading in its entirety

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…
