Notes from Half Way

Posted in Biographical, Covid-19, Education, Maynooth with tags , , , , , , on November 6, 2021 by telescoper

We’ve now reached the halfway point in our teaching semester at Maynooth University. That means there are another six weeks of teaching before the end of term break. I was looking through the notes of my modules this morning in order to make a plan for the rest of term and was relieved to find that I’m roughly on track to finish on time. That is despite the first years starting a week late and lectures being 45 minutes long instead of 50.

At this point I’m still finding it very disconcerting talking to an audience of masked students, but it’s a heck of a lot better than just talking at a camera. Quite a few times I’ve been walking around campus and a student without a face covering has said “hello Peter” or words to that effect and I’ve smiled and said “hello” back while wondering who they were. Outside, you see, people take their masks off while, inside, I’m the only person whose face is uncovered.

Still, at least during lectures I get to make eye contact with the students. I don’t know why that matters so much to me, but it does. I remember as a student I had some lecturers who were pathologically incapable of making eye contact with the class, usually staring at a spot about six feet over the heads of the students. I found that most off-putting.

Although it still feels a bit weird, I’m glad that the mask-wearing protocol is being observed very well at least in lecture theatres. Unfortunately cases are skyrocketing right now – almost 4000 yesterday, as high as last January – which is all very worrying. Are we going to move to a Plan B? I doubt it, because the Government doesn’t seem to have one. Nevertheless I do think there’s still a significant possibility of our January exams being moved online yet again, but that hasn’t been decided yet.

Meanwhile, in the UK, University staff have been balloted over industrial action relating to the USS pension scheme and to various issues relating to terms and conditions. The majority of votes cast were in favour of strikes, but some institutions did not reach the 50% threshold required for strike action to be legal (some by just a handful of votes) and others achieved the threshold in only one of the disputes. I don’t know what will happen next, but I’d like to express my solidarity with those taking what I consider to be entirely justified action.

I couldn’t resist quoting this from the Universities UK statement on the dispute:

After a difficult 18 months, students do not deserve any further disruption.

Yes, it has been a difficult 18 months for students, but the absence of even a teeny bit of recognition that it has also been very difficult for staff is extremely telling.

I’m taking a particular interest in the disputes not only because I have friends and former colleagues in the UK but also because I have the best part of 30 years’ contributions locked into the USS pension scheme, plus some additional voluntary contribitions, and am relying on the benefits from those for my own retirement. If anything happens to that source of income I am financially screwed.

Apart from the USS scheme, the other side of the UCU dispute concerns ‘four fights‘ over:

  1. Pay
  2. Workload
  3. Equality
  4. Casualisation

These issues don’t only apply in the UK, of course. Workloads in my Department are at ridiculous levels – not only for me – and we have been forced by Management decisions into a situation in which half of our lecturing is being done by staff on short-term contracts. I suspect that the unpaid overtime we have put in during the pandemic is the expectation for the future, and I see no sign of the casualisation of our teaching staff being reversed in the immediate future. I hope I’m proved wrong, but in the meantime I’m keeping a close eye on my USS pension in case early retirement proves the only way to escape…

Astrophysics & Cosmology Masterclass at Maynooth!

Posted in Biographical, Education, Maynooth, The Universe and Stuff with tags , , on November 4, 2021 by telescoper

Regular readers of the blog – both of them – may remember that, after a couple of postponements due to Covid-19, we presented a Masterclass in Astrophysics & Cosmology in Maynooth on March 25th 2021. Well, owing to popular demand, we’ve decided to do a re-run of the event on Friday 12th November 2021 ahead of the forthcoming CAO cycle. That’s a week tomorrow!

This will be a half-day virtual event via Zoom. It’s meant for school students in their 5th or 6th year of the Irish system. There might be a few of them or their teachers who see this blog so I thought I’d share the news here. You can find more information, including instructions on how to book a place, here.

Here is the updated official poster and the programme:

I’ll be talking about cosmology early on, while John Regan will talk about black holes. After the coffee break one of our PhD students will talk about why they wanted to study astrophysics. Then I’ll say something about our degree programmes for those students who might be interested in studying astrophysics and/or cosmology as part of a science course. We’ll finish with questions either about the science or the study!

I’m told that with a week still to go we already have over 750 science students based in schools from An Daingean to Arranmore Island, from Monaghan to Mayo and many counties in-between. Fortunately it is online so no travelling is involved. Unfortunately the participants don’t get to see the wonderful campus so here’s a gratuitous picture!

(And at 12 noon I don’t turn into a pumpkin but do have to run off to give a lecture on vector calculus..)

A Time to Confer

Posted in Biographical, Education, Maynooth on October 27, 2021 by telescoper

Booklet Cover

This morning I braved the inclement weather to attend a Conferring Ceremony at Maynooth University. This was the first Conferring Ceremony to be held in person since for about two years and the first ever featuring the new President of Maynooth University, Prof. Eeva Leinonen, presiding.

There were only four students from Theoretical Physics graduating this morning, and two of them graduated in absentia but I did get to see two students get their Master of Science by Research awards. If you’re interested their theses are available online here and here.

I wouldn’t say the ceremony went off without any hitches. There were quite a few late arrivals among the graduands. I think the bad weather elsewhere in Ireland caused some delays which led to some people being late for the ceremony (which was due to start at 10am, but didn’t get going until about 10.30). Then there were some last minute changes of order which led to one or two students initially getting the wrong scroll. I remember how nerve-wracking it was when that sort of reshuffling happened when I was involved in similar ceremonies at Sussex. It’s bad enough stressing over the correct pronunciation of the names! Anyway I was glad that these days all I have to do is sit there.

The last conferring ceremony I attended in person was on October 31st 2019. It was while I was en route to give a talk at DIAS that evening after the ceremony that I heard that my Mam had passed away. So much has happened between then and now that it is hard to accept that was only two years ago…

Bank Holiday Break

Posted in Biographical, Maynooth on October 23, 2021 by telescoper

So here we are then, five weeks of teaching over, we have reached the mid-term break. I actually thought it was quite unusual to reach study week after 5/12 of the Semester rather than half, but it seems it happened as recently as two years ago. The pandemic has played havoc with my powers of recollection as well as other things. Anyway, this Monday (25th October) is a Bank Holiday in Ireland. The last Monday of October (Lá Saoire i mí Dheireadh Fómhair), or the Halloween Holiday (Lá Saoire Oíche Shamhna), is always a national holiday here, although Halloween itself isn’t until next Sunday.

I’ve got a big backlog of work things to do, but I can’t face it right now so I’m going to take the long weekend off and use Tuesday to Friday to try to tackle the to-do list (apart from Wednesday, when I have to attend a Conferring Ceremony).

In the meantime I will be doing nothing more strenuous than a bit of gentle gardening, including clearing away the leaves and tackling the last bit of ivy threatening to invade my house.

On the subject of gardening, I’ve noticed that I’ve got a fine crop of toadstools on the back lawn. I don’t know enough about fungi to know whether they are toxic, edible or even hallucinogenic, though I think if they were edible the birds would have a go at them. Any experts who can identify the type shown please feel free to let me know!

It’s always puzzled me how many people thing that there must be something wrong with their garden if there are toadstools in it. As far as I’m concerned they are part of the natural ecosystem so I just let them grow. I find them quite fascinating. They only live a few weeks so will disappear in due course without any intervention from me.

Chalk and Talk

Posted in Biographical, Education, Maynooth with tags , , , , on October 22, 2021 by telescoper

Today is the last day of teaching ahead of next week’s mid-term break. As it happens I did two consecutive lectures from 11-1 today instead of the usual one from 12-1 because of a rearrangement necessitated by a staff absence. I don’t mind admitting that I’m looking forward to a bit of a pause during Study Week, before embarking on the remaining 7 teaching weeks of the Semester.

The room I give my 12-1 lecture in has a chalkboard but the one for the 11-12 slot only has a whiteboard. The downside of the whiteboard is that it is almost impossible to make a lecture recording because the contrast is too low. I was happy to move to the usual room for the second one, which isn’t great either but at least has a decent blackboard.

A still from one of last year’s Engineering Maths lectures from home…

I know people think I am very old fashioned in persistently using a chalkboard. They also find it quite amusing that I bought one especially so I could do lectures from home using it. It’s far easier to get a decent contrast than using a whiteboard and I find that standing up and walking around allows me to communicate more effectively, at a decent pace and with a reasonable amount of energy. Most importantly of all I think it’s important for the students to see a process unfolding.

It’s proving much more difficult to provide decent quality lecture recordings on campus than at home because of the lack of decent camera facilities, but I’m doing the best I can.

Anyway, I was pleased to find a recent article about why Mathematics professors at Stanford University still use chalkboards. I agree with everything in it and will continue to use chalk and talk as long as I can. The way things are going with Covid-19 I may even be using the one at home again before too long…

The Irish Svarabhakti

Posted in Biographical, History with tags , , , , on October 21, 2021 by telescoper

One of the things I’ve picked up about Hiberno-English pronunciation is that Irish people tend to pronounce the English word “film” as something like “fillum”. I always thought this was just a sort of mannerism, but it turns out to be quite a bit more interesting than that.

The general term for the addition of an extra sound to the pronunciation of a word is epenthesis and it is a fairly common feature of many languages. The extra sound can be added at the beginning, at the end or in the middle. The latter case is specifically called anaptyxis or sometimes svarabhakti, which is a Sanskrit word specifically for the insertion of a vowel after the letter l or r before another consonant.

In most cases these extra vowel sounds are inserted to aid pronunciation, If you think about it the mouth and tongue have to do something quite complicated to get from l to m and a nice easy “uh” sound makes the transition simpler.

The Celtic group of languages was the first wave of Indo-European languages, to sweep across Europe. I blogged about this here. It seems the idiosyncratic pronunciation of “film” as “fillum” (which, I’m told, is also in widespread use in India) is a relic of the Irish language’s distant origins in Sanskrit, having no doubt crossed into Hiberno-English at a time when Irish was more widely spoken than it is now.

Another topical example is the name Colm (as in Colm Tóibín), which is pronounced “Collum” (or, depending on dialect, something more like “Cullum”).

Anaptyxis isn’t restricted to Irish, of course. There are examples in English. Who could forget the form favoured by football supporters? Engerland! Engerland! Engerland! (I don’t remember the rest of the lyrics to that song…)

Windows, Bugs and Updates

Posted in Biographical, Maynooth with tags , , on October 13, 2021 by telescoper

While having breakfast at home this morning I noticed that my laptop was asking for a restart to complete Windows update. Since this machine was set up by my employer’s IT services, it has BitLocker installed which means I have to be present to type in a PIN every time it restarts. It is therefore not possible to schedule updates overnight, as a sensible system would allow. In fact I can’t adjust very much at all about the update policy. All of this explanation is meant as an excuse for why I made the rookie error of restarting it before going to work.

Three restarts later, at 10am, I finally decided to go into work. I should have waited until then before starting the updates because my desktop machine works on Linux and is immune from Windows update nonsense so I would have been able to get on with other stuff while my laptop was starting and restarting.

Anyway, when I did arrive in the office, the laptop wanted to do yet another restart. That’s four altogether (so far); the latest one having taken much longer than the others. Had I been at home and relying on my laptop I would have wasted an entire morning.

I did think that perhaps the updates manager on my laptop had gone berserk and this plethora of starts and restarts was some kind of bug. It turns out though that it wasn’t: since yesterday, Microsoft has been flooding the internet with huge updates and patches of various kinds, mainly to fix “vulnerabilities” of various kinds. There’s been quite a lot of comment on social media about this from people (including myself) fed up with the state of their computers.

One of the vulnerabilities I know about concerns the print spool Windows er, which apparently was in a state that allowed it to be easily hacked. The solution chosen by my employer’s IT Services team was to disable all printing by shutting down the print spooler on University machines. After sending an inquiry to the system support people they recommended that if I wanted to print something I should manually restart the spooler, print the document, then manually terminate the spooler again. If I wanted to print several documents I should do this for each one…

Yeah, right.

I have no idea how many person-hours are being wasted by these vulnerabilities nor how much bandwidth is being used up worldwide to fix these Windows bugs. Unfortunately I don’t think it’s possible for organizations to sue Microsoft for lost productivity…

Del or Nabla?

Posted in Biographical, mathematics with tags , , on October 12, 2021 by telescoper

I am today preoccupied with vector calculus so, following on from yesterday’s notational rant, I am wondering about the relative frequency of usage of names for this symbol, commonly used in math to represent the gradient of a function ∇f:

To write this in Tex or Latex you use “\nabla” which is, or so I am told, so called because the symbol looks like a harp and the Greek word for the Hebrew or Egyptian form of a harp is “nabla”:

When I was being taught vector calculus many moons ago, however, the name always used was “del”. That may be a British – or even a Cambridge – thing. Here is an example of that usage a century ago.

Anyway, I am interested to know the relative frequency of the usage of “nabla” and “del” so here’s a poll.

There may be other terms, of course. Please enlighten me through the comments box if you know of any…

Weekend Jobs

Posted in Biographical, Maynooth on October 10, 2021 by telescoper

If I ever used to feel guilty about not working at weekends I don’t anymore. I may have a big backlog of things to do but I’ve come to accept that life is too short to work every day of the week.

I’ve explained many times on this blog that we’re very short-staffed in the Department of Theoretical Physics. That is no fault of mine or any of the other staff so I’m not going to work myself into the ground. I did enough unpaid overtime during the lockdown and I’m not going to allow stress and overwork to become the new normal.

So, despite toying with the idea of finishing a paper this weekend, I settled for domestic chores. That doesn’t make for a very exciting blog post but there you are.

The main task I accomplished was to deal with the ivy that is growing in profusion on the outside of my house. It was in danger of getting into the loft space so I got my flat-bladed chisel out and went at it. It’s nearly all cleared now, but my garden waste bin is full so I’ll have to do the rest when I have space to put the bits and pieces.

It being October now I’ve also resumed food service for the birds. I put out one feeder last week and it was emptied in a matter of hours. I saw mainly blue tits attacking it. I haven’t seen any of those for a while. I forgot to buy peanuts but I’ll try to do that in the week so I can deploy the mesh feeders; the seed I’ve already put out is too fine for those.

Another exciting job I did was clean out my coffee maker. I have a nice espresso machine that requires regular de-scaling. That takes quite a while to do as one has to send a whole tank full of solution through the works, then rinse it out with water afterwards.

I also put a few pictures up, having rescued my Black-and-Decker from the shed. I still have more to do, largely because I’m very indecisive about where to put my artwork. I still have to hang my big blackboard too. I might be needing it for online lectures again. Who knows?

Other than the highlight of the weekend was Saturday night dinner, which was roast confit of duck with braised red cabbage, roast Romanesco with garlic and lemon, and new potatoes. It was delicious, especially when accompanied by a very nice Barolo. I even enjoyed shopping for some of the ingredients.

Anyway, week four begins tomorrow. That’s a third of the way into term for the returning students. I don’t think I’ve ever started counting the days to the end of term this early before.

Three Weeks In…

Posted in Biographical, Maynooth on October 8, 2021 by telescoper

Today marks the end of the third week of the Autumn Semester in Maynooth, which is also the end of the third week of teaching for returning students and the end of the second week of teaching for new arrivals. I was talking to some friends from Cardiff yesterday and expressed relief that the daily number of new cases seemed to be falling despite the return of students to campus.

Today, however, the number of positive test results reported was 2002, which is a big increase on recent days. Last Friday’s figure was 1059 and the intervening numbers have been hovering around the 1000 mark. I was quite shocked when I saw the latest number.

The latest data for students testing positive in Maynooth are for the week ending October 3rd, during which there were only 7 cases. I’d be interested to see whether those numbers have risen significantly.

The latest increase doesn’t look much on the 7-day average, and it might just be a blip. After all, we’ve had plenty of those over the last 18 months! I was just starting to relax because of the falling curve but now I am very worried.

I have to say that the students have behaved impeccably in my classes. If there has been an increase in transmission associated with the return to campus it seems more likely to me that it is associated with social activities, or travelling on crowded public transport.

The reason I am so concerned is partly that I really don’t want to have to switch everything back online again like we did last year, but more immediately that we are so short-staffed this year that if any lecturer or tutor falls ill we have no spare effort available to provide cover. We still have one lecturer without a visa having to give lectures remotely. Our increased student numbers this year make this an especially bad time to be short of teaching staff.

Well just have to wait and see how things develop over the next few days and weeks, but I could do without this stress!
