Physics as Fun

Posted in Biographical, Education, Maynooth on September 13, 2023 by telescoper

To add to all the excitement I’ve just had a visit from a representative of ESB Networks who installed a new “smart” meter at my house in Maynooth. That process involved cutting off the electricity for about 15 minutes, which was long enough to set off my burglar alarm. Now that’s sorted, I have to go round resetting the clocks. All of that after I wasted half an hour this morning watching my laptop do compulsory Windows updates which involved two restarts.

Anyway, despite the distractions I’ve been working busily at home and getting ready for my departure abroad. This is the first year for a while that I haven’t been involved in Welcome Week or the Student Orientation process, which are ongoing. I have, however, looked at the online registrations so far and confirmed that there will indeed be some students in Theoretical Physics for the forthcoming academic year.

Yesterday I saw this cartoon by Gary Larson so thought I’d share it here.

It reminded me of this picture I have in the past shown at Open Days

I think there are many people out there who think physics, especially theoretical physics, isn’t something to be enjoyed. I think it is, or at least that it can be. I also think the best way to succeed at physics is by enjoying it, and I hope the new and returning students at Maynooth enjoy their theoretical physics over the next year while I am slaving away on sabbatical in Barcelona…

From Einstein to Euclid: the Gallery

Posted in Biographical, Maynooth, The Universe and Stuff with tags , , on September 11, 2023 by telescoper

Last week I posted a photograph taken during my public lecture at Maynooth University. I thought I’d compound your collective misery by putting up more. I’m not sharing any pics of the audience because we didn’t ask them for permission, so you’re basically stuck with pictures of me (and one of Joost Slingerland, our Head of Department, in the first one).

Thanks to Dale for taking the pictures!

Brahms, Byrne & Berlioz at the NCH

Posted in Biographical, Music with tags , , , , on September 9, 2023 by telescoper

Last night I went to the Opening Concert of the new season by the National Symphony Orchestra at the National Concert Hall in Dublin. I’ll be away for most of the year, so I thought I’d make the most of the time I’ve got before I depart to get a fix of culture.

This year is the 75th anniversary of the founding of the National Symphony Orchestra, and the very first piece they performed at their very first concert back in 1948 was Academic Festival Overture by Johannes Brahms. I found it an especially fitting piece because this week we have been having graduation (conferring) ceremonies all week in Maynooth. It’s a familiar work, but provided an enjoyably upbeat start to the show.

The next piece was a a world premiere of a special commission for the National Symphony Orchestra. I was looking forward to this because it was to be the first time I’ve ever heard the uilleann pipes on the concert stage. The piece is a lot of fun, full of great tunes and robust humour. The uilleann pipes are a rather quiet instrument, however, and I have to say I hardly heard a note from them over the rest of the orchestra. At the end a Scottish piper walked on stage to play the bagpipes during the finale. These pipes are a much louder instrument, and even they were hard to hear with the rest of the band on full throttle.

Anyway, after the wine break, we had the Symphonie Fantastique by Hector Berlioz. I was put off this piece at school by a teacher who was obsessed with it and spent nearly a whole term banging on about how wonderful it is. While it is undoubtedly very imaginative – and very innovative for a piece written as early as 1830 – I remain unconvinced by all the hype. It’s basically a fever dream resulting from the composer’s experiments on opium and I find it rather gimmicky. Nevertheless, there is much to enjoy in a live performance of the work. Conductor Jaime Martín began the performance with a genial introduction to some of the “crazy” elements which he got the relevant musicians to play snippets representing, for example, the bubbling cauldron in the last movement which represents witches doing their stuff.

After the full performance the National Symphony Orchestra got a standing ovation. I joined in only briefly because the conductor’s introduction to the Berlioz meant that the concert was longer than I expected and I had to leave to catch my train back to Maynooth. I needn’t have worried. The train was 20 minutes late.

The Universe from Einstein to Euclid

Posted in Biographical, Talks and Reviews with tags , , on September 7, 2023 by telescoper

As we head into the Day 2 of the ITP2023 I thought I’d share the slides I used for the public talk I gave last night. We had an audience of around a hundred which wasn’t bad given that it is graduation week and the undergraduates aren’t back!

Here is the abstract used to advertise the talk:

Euclid is the name of a new scientific mission from the European Space Agency, launched on July 1st, designed to explore the composition and evolution of the Universe. The Euclid mission takes its name from the ancient Greek mathematician regarded by many as the Father of geometry. Until the last century, Euclid’s theorems were assumed not just to be mathematical notions, but to describe the geometrical structure of the physical Universe. Einstein’s general theory of relativity swept that idea aside and gave us new ways of describing space, by unifying it with time, and by allowing it to be affected by matter in a manner very different from that formulated by Euclid. Over the past century, this theory has proved to be very effective at describing the properties of the Universe as observed by modern astronomical telescopes, while also suggesting the existence of dark matter and dark energy.

The Euclid telescope will create an enormous map of the large-scale structure of the Universe across space and time by observing billions of galaxies out to 10 billion light-years, across more than a third of the sky. Euclid will explore how the Universe has expanded and how galaxies and clusters of galaxies have formed over cosmic history, and how space itself is distorted by these structures.

This talk will discuss our modern ideas of space and time, how the Euclid mission will try to test whether or not they are correct and shed light on the nature of dark matter and dark energy.

And here are the slides:

Obviously I cut a number of long stories very short, which probably contributed to why I had a lot of questions from the audience at the end of the talk. I always assume that’s a basically a good sign because it shows people are interested, but it also makes me worry that I didn’t explain things very well!

We didn’t finish until past 9 o’clock and it was a very warm evening, so I was very happy to have a few pints afterwards in O’Neills…

ITP 2023

Posted in Biographical, Education, Maynooth, The Universe and Stuff on September 6, 2023 by telescoper

So here we are then, first day of the 2023 Irish Theoretical Physics meeting here in Maynooth. It’s a busy schedule for the three days, followed by a little meeting on Saturday to mark the retirement of Brian Dolan

It’s been a busy day for reasons other than the ITP2023 and I’ve left it a bit late to write my talk for this evening’s public lecture so I’d better get on with that this afternoon.

Updates to follow.

September Heatwave

Posted in Biographical, Maynooth with tags on September 4, 2023 by telescoper

What a lovely day to be on sabbatical! It seems that the weather is set fair for a few more days too, which is nice. You don’t often see a satellite image with not a cloud in the sky over Ireland.

It’s cute that the Met Éireann weather map gives a red temperature warning when it’s just 23 °C.

Mind you, it has felt very warm today. So much so that I had a short nap this afternoon. I think of this as training for what I hope will be the regular siesta…

The Sabbatical Starts Here…

Posted in Biographical, Maynooth with tags , on September 1, 2023 by telescoper

Today is 1st September 2023, which means that it is the first day of my year-long sabbatical. No teaching and no admin until 31st August 2024! I moved the last of my personal things out of the office yesterday and put an auto-reply on my email. I did plan to take today off to celebrate but I had some things to do relating to the Open Journal of Astrophysics so I spent the morning doing them. If the rain holds off I might do a spot of gardening later on.

A sabbatical isn’t a holiday of course, and will have plenty to do over the next year, much of it clearing a backlog of things I should have done well before now but failed because of workload issues. I make no apology for taking the first day off, however.

Next week will be quite busy. I will be attending a meeting in Maynooth next week and giving a public talk, which gives me the chance to post a reminder that it’s not too late to register for either/both:

Another thing I did last night was to deactivate my own personal Twitter account as well as the one for the Open Journal of Astrophysics. Twitter is both unpleasant and useless these days and I can’t be doing with it anymore. I had been on it for 14 years and had accumulated over 7,000 followers. Those that want to carry on following me on social media will find me on BlueSky or Mastodon. The same goes for those who followed the Open Journal of Astrophysics on Twitter.

Anyway, in a fortnight or so I should be heading off to distant lands. I’m greatly looking forward to getting away and being able to concentrate on things to do with research for a change. I’m looking forward to the temporary change of location, not least because a warmer climate might help with my arthritis…

Not a Bank Holiday Monday

Posted in Biographical, Maynooth on August 28, 2023 by telescoper

So here I am, back at my desk in my office at Maynooth University. Today is a Bank Holiday in parts of the United Kingdom but not here in Ireland: we had our August Bank Holiday on the first Monday of the month rather than the last. I could say that today is a normal working day, but it’s not really because it’s been a bit busier than usual. After a few days away last week, I’ve had quite a lot to catch up, including preparing two new publications at the Open Journal of Astrophysics. I also have a Euclid telecon this afternoon, though I’m not sure how many UK participants will be there given the fact that today is a public holiday.

My sabbatical officially starts on 1st September 2023 and I’m looking forward to putting my “out-of-office” message on and (selectively) ignoring emails for a year. Although a sabbatical isn’t a holiday, I plan to take Friday September 1st off after having a few drinks on Thursday evening.

Before that I have to remove the last of my personal things from this office as it will be needed for someone else. That will give me the excuse for a big clear out of things I no longer need. This process will temporarily reduce the entropy of the room, although it will increase elsewhere I will not violate the 2nd Law of Thermodynamics.

I decided some time ago that at the end of August, I would delete my account on the platform formerly known as Twitter. Those of you that want to continue following me on social media can do so via any or all of the the following:

The Returning and The Leaving

Posted in Biographical, Education, mathematics, Maynooth, Politics with tags , , on August 26, 2023 by telescoper

I got back to Maynooth last night after a pleasantly uneventful train journey. Just for the record both outward and return trips were perfectly on schedule. In fact it has been a very pleasant couple of days. Congratulations to the organizers for running the meeting so well and to all the speakers for delivering such an interesting programme. Next year’s INAM will be in Galway. I’m looking forward to it already!

Anyway, now I’m back I should mentioned that the 2023 Leaving Certificate results were released to students yesterday; the first round of CAO offers will go out on Wednesday 30th. Soon after that we will find out how many students we’ll have next year. Student enrolment begins on 11th September; Orientation Week for new students starts on Monday 18th September; and lectures start the following Monday (25th). I am on sabbatical for a year from next Friday (1st September) so I won’t be teaching the new students, but I know they’ll be in capable hands.

There’s a lot of discussion – much of it poorly informed – in the media about grade inflation in the Leaving Certificate (e.g. here). This happens every year (as it does with A-levels in the UK), and its very sad that people use this occasion to publicly disparage the accomplishments of students. The students can only take the examinations that are put in front of them. Any problems with the system are not their fault at all.

This year the problem stems from a decision by Minister for Education Norma Foley to impose a condition that overall grades this year would not be lower than last year. This has led to the deployment of scaling which has resulted in an uplift of around 8%. The Higher Mathematics Leaving Certificate results also benefitted from an alteration of the marking scheme because one of the papers was deemed to be too hard. Despite this, the number of students receiving the top grade of H1 fell this year from 18% to under 11%. One might argue that this disadvantages students applying to courses that actually require mathematics compared to those that don’t.

There seems to be a widespread misunderstanding that the CAO points required for a course is somehow a measure of the level of difficulty of that course. In most cases this is not the case: having a high points threshold is basically just a way of controlling the number of students allowed in. I find the connection that has been made between grade inflation and drop-out rates extremely unconvincing. High drop-out rates in recent years are probably dominated by the pandemic, housing crisis and cost of living increases, leading to many students struggling to study effectively.

During the pandemic years, grades were inflated by including coursework rather than examinations, a change enforced because of public health restrictions. The main argument for deliberate grade inflation this year was to prevent this year’s LC students being disadvantaged with respect to last year’s. It doesn’t seem to have occurred to the Government that the same argument could be used next year, and indeed forever. Fairly typically for a politician, kicking the can down the road for the next government to deal with seems to be strategy.

As a final thought, I find myself wondering what will happen to admissions at Maynooth this year. Will the decision by The Management to scrap the promised Student Centre have a big effect? And what about the further reputational harm caused by the recent furore over the Governing Authority? I suppose we’ll find out next week!
