Student Feedback and Lecture Recordings

Posted in Cardiff, Education, Maynooth with tags , , on April 19, 2023 by telescoper

This afternoon we had a very interesting meeting about teaching in the Department of Theoretical Physics at Maynooth University, involving teaching faculty and student representatives from each year of each of the courses we offer.

It was nice that most of the feedback gathered by the student reps from their peer groups was positive. For one thing, they really like the blackboard-based teaching we use to deliver most of our modules. Most of the negative comments, however, related directly to lack of resources.

A particular concern, expressed unanimously by all the student reps at the meeting, was the lack of lecture recordings. I don’t think I am alone among the teaching staff in the Department in saying that I wish we could offer lecture recordings as routine. Unfortunately, however, and much to my disappointment, the Senior Management at Maynooth University has discouraged lecture recording as a matter of policy and has not invested in the technology required to make this possible so it is not practicable anyway.

My two previous employers – the University of Sussex and Cardiff University – both had systems in place long before the Covid-19 pandemic and all lectures were recorded as standard . I blogged about this 8 years ago, in fact. In my view the benefits of lecture capture far outweigh the disadvantages, and we should incorporate recordings of lectures as part of our standard teaching provision, as a supplement to learning rather than to replace face-to-face sessions. Every student learns in a different way and we should therefore be doing as much as we possibly can to provide a diverse range of teaching resources so that each can find the combination that suits them best. Technology allows us to do this far better now than in the past.

Some really enjoy live in-person lecture sessions, especially the ability to interact with the lecturer and the shared experience with other students, but others don’t like them as much. Others have reasons (such as disability) for not being able to attend in-person lectures, so providing recordings can help them. Others still have difficulty attending all lectures because of a dratic shortage of student accommodation. Why not in any case provide recordings for everyone? That seems to me to be a more inclusive approach.

The problem with lecture capture in Maynooth is that we will need to improve the cameras and recording equipment in the large lecture rooms to make it possible for lectures with a significant mathematical content. The existing setups in teaching rooms do not easily allow the lecturer to record material on a whiteboard or blackboard. In Cardiff, for example, the larger rooms have more than one camera, usually one on the lectern and one on the screen or whiteboard (which has to be placed further away and therefore needs to be of higher resolution). In Maynooth we only have small podium cameras in the teaching rooms. In fact I have far better facilities in my study at home – provided at my own expense – than my employer is prepared to provide on campus.

I’m baffled and frustrated by Maynooth’s decision in this matter, which is generating a great deal of negativity amongst faculty and students alike. I hope The Management can be persuaded to change its mind. Persisting with the current policy would send a clear message that teaching and learning are not valued at Maynooth. Maybe they just aren’t?

P.S. The single most common inquiry I have received about the new MSc course announced recently has been whether it is possible to take it remotely. Given our lack of recording facilities, regrettably the answer to this is “no”.

Astronomy Plot of the Week

Posted in The Universe and Stuff with tags , , on April 19, 2023 by telescoper

Pictures made by observational astronomers, like the one I featured a couple of days ago, often feature on various sites as “Astronomy Pic of the Week” or such. I’ve often thought that this disadvantages astrophysicists of the more theoretical sort and wondered why don’t we do same with graphical illustrations of other kinds. On that basis, I offer this (found here) as my inaugural Astrophysics Plot of the Week:

Its explanatory power is matched by its simplicity and elegance.

New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , on April 18, 2023 by telescoper

Back after a short hiatus due to the Easter holidays, it’s time to announce yet another new paper at the Open Journal of Astrophysics. This one was accepted for publication a few weeks ago but the final version only appeared on the arXiv yesterday. Since OJAp is an arXiv-overlay journal, we have to wait for authors to upload the accepted version before we can publish the overlay.

Anyway, the latest paper is the 12th paper so far in Volume 6 (2023) and the 77th in all. This one is in the currently under-populated folder marked Solar and Stellar Astrophysics and its title is “Predicting Stellar Mass Accretion: An Optimized Echo State Network Approach in Time Series Modeling”.

The authors are: Gianfranco Bino, Shantanu Basu & Ramit Dey (all at the University of Western Ontario, Canada), Sayantan Auddy (Jet Propulsion Laboratory, Pasadena, USA), Lyle Muller (University of Western Ontario, Canada) and Eduardo I. Vorobyov (University of Vienna, Austria & Southern Federal University, Russia).

Here is a screen grab of the overlay which includes the  abstract:

R.I.P. Ahmad Jamal (1930-2023)

Posted in Jazz, R.I.P. with tags , , , on April 17, 2023 by telescoper

With the passing, on Sunday, of Ahmad Jamal, at the age of 92, another legendary Jazz musician has left us. He was a consistently inventive pianist, of great elegance, and a wonderful knack of deconstructing a tune into its component parts before reassembling it into something fresh. His formative years were a time when many keyboard players emphasized virtuosic brilliance, but Jamal’s approach was relaxed and spare. He was great letting his story develop gradually but very enjoyably through a series of riffs over a compelling rhythmic foundation. A perfect example is this track, Poinciana, from a hugely popular album Live at the Pershing: But Not For Me, recorded in 1958 with Israel Crosby on bass and Vernel Fournier on drums. Ahmad Jamal is no longer with us, but this groove will last forever!

Maynooth Astronomy Picture of the Week!

“A Stellar Sprinkler”

I think for the first time, Maynooth astronomers have been featured in the European Space Agency’s Picture of the Week. Here is the blurb from ESO:

–o–

This Picture of the Week shows the young stellar object 244-440 in the Orion Nebula observed with ESO’s Very Large Telescope (VLT) –– the sharpest image ever taken of this object. That wiggly magenta structure is a jet of matter launched close to the star, but why does it have that shape?

Very young stars are often surrounded by discs of material falling towards the star. Some of this material can be expelled into powerful jets perpendicularly to the disc. The S-shaped jet of 244-440 suggests that what lurks at the center of this object isn’t one but two stars orbiting each other. This orbital motion periodically changes the orientation of the jet, similar to a water sprinkler. Another possibility is that the strong radiation from the other stars in the Orion cloud could be altering the shape of the jet.

These observations, presented in a new paper led by Andrew Kirwan at Maynooth University in Ireland, were taken with the Multi Unit Spectroscopic Explorer (MUSE) instrument at ESO’s VLT in Chile. Red, green and blue colours show the distribution of iron, nitrogen and oxygen respectively. But this is just a small fraction of all the data gathered by MUSE, which actually takes thousands of images at different colours or wavelengths simultaneously. This allows astronomers to study not only the distribution of many different chemical elements but also how they move. 

Moreover, MUSE is installed at the VLT’s Unit Telescope 4, which is equipped with an advanced adaptive optics facility that corrects atmospheric turbulence, delivering images sharper than Hubble’s. These new observations will therefore allow astronomers to study with unprecedented detail how stars are born in massive clouds like Orion.

There’s also a little video showing how the picture was made using MUSE:

Congratulations to Andrew Hirwan and supervisor Emma Whelan from the Department of Experimental Physics for this coup!

The Cyclic Universe of the UK Astronomy Grant System

Posted in Biographical, Science Politics, The Universe and Stuff with tags , , , on April 17, 2023 by telescoper

I stumbled by accident yesterday on a bit of news relating to UK Astronomy Grant funding via the Science and Technology Facilities Council (STFC). I am of course completely out of that system, and have been for years, but I am nevertheless quite nosy so was interested to find out about the changes. Thanks to Alan Heavens and Paul Crowther for enlightening me.

Way back in 2010 I wrote in somewhat critical terms about the new-style Consolidated Grants that STFC was planning to introduce. This system replaced a dual approach of so-called “Standard Grants” – which were typically rather small, usually funding one postdoctoral researcher and bits and bobs – and “Rolling Grants” – which were usually larger, covering all the activities of a department or institution – with a single system of “Consolidated Grants”. The Standard Grants were “responsive”, in that investigators could put in an application whenever they wanted, whereas Rolling Grants were on a fixed timetable. After the change, the responsive mode went out the window and Departments were forced to apply collectively, once every three years.

Much of the reason for the change was the administrative cost of the system. There were huge numbers of standard grant applications. Back in the mists of time there were two application deadlines per year so it was a heavy burden on the panels and the Swindon office, especially since so little funding was available in the first place. Standard grants were also the first to get squeezed when there was a funding shortfall, whereas Rolling grants generally carried on rolling.

Well, the news is that the current Astronomy grant round, with applications in 2022 and grants starting in 2023, will see the last of these Consolidated Grants. From this year on, there will be a new system of – wait for it – “Small” and “Large” grants, thought these are officially called Type 1 and Type 2. The Small Awards scheme is described here and it looks very much like the old Standard Grant system. Details of the Large grants scheme are not yet available, but I believe they will start next year. You can find more details here (PDF).

So now it seems something very like the old system is returning, and there are no doubt the same worries that Large grants will eat up most of the money, leaving very little for the Small grants. Déjà vu.

Anyway, the way I came across this piece of news was via the announcement of a clutch of PDRA positions in cosmology and extragalactic astrophysics at the University of Sussex (where I worked from 2013-16). It seems the Astronomy Centre must have done pretty well in the (final) STFC Consolidated Grant round, which is very good to hear! It seems there might be a bit more money generally in the grant line this year too, which is also good news.

The Other Side of Easter

Posted in Biographical, Maynooth with tags , on April 16, 2023 by telescoper

I haven’t been reading my work email for a few days as I’ve been working from home during the recent Easter mini-break and wanted to catch up on a few things without too many distractions. Having to return to campus tomorrow, however, I decided with some trepidation to see what had accumulated in my inbox while I wasn’t looking and got a rather pleasant surprise.

Just before Easter I mentioned that I had been granted a half-year sabbatical for next academic year. Well, reading my email this morning I found a letter saying that it had been decided to change that to a full year, which is what I originally requested:

The period of sabbatical leave granted is from 1st September 2023 to 31st August 2024.

So having spent a bit of time thinking about how to spend the reduced period, I’m now back to square one (but in a good way). I’m not sure why the powers that be changed their mind on this. Perhaps they’re even keener to get me out of the way than I thought?

The revised schedule means that I will still be around in Maynooth for the August repeat examinations (and marking thereof), but I hope to leave shortly after that is all done and dusted. I’m sure I will miss the teaching next year, but I’m looking forward to being able to concentrate on research and to working in a different environment for a time.

All this means that we will shortly have an advertisement for a sabbatical replacement lecturer in the Department of Theoretical Physics at Maynooth University to cover my teaching while I’m absent. Watch this space. Obviously I will help advertise the position, but I can’t play any further role in the recruitment process.

Anyway, the immediate focus of my attention will be the remaining three weeks of teaching for this Semester. I have a couple more Computational Physics laboratory sessions to organize, as well as the final batch of lectures for Advanced Electromagnetism. That will be followed by an intense period of grading project work, revision lectures, and finally correcting examination scripts. The Examination Period in Maynooth starts on Friday 12th May, but the two with which I am directly involved take place on Thursday 18th and Saturday 20th.

But for now, back to my inbox…

Voices

Posted in Biographical, Education, Poetry with tags , , , on April 15, 2023 by telescoper

Not long ago I did a post about an anthology of Poems I studied at school many years ago. I bought that second-hand at the same time as I bought the three volumes shown above, Books 1-3 of Voices (edited by Geoffrey Summerfield). I seem to remember that we studied these at an earlier stage of 11+ education, probably in consecutive years before O-level. I remember the covers quite well, especially the rather spooky picture on Book 3.

They’re quite interesting books, each of which contains an eclectic collection of poems, including traditional rhymes and there is even some music at the back to accompany some of the verses that work as songs.

Anyone else remember these books?

Why Are Universities So International?

Posted in Biographical, Education, Maynooth on April 15, 2023 by telescoper

This is an interesting post about internationalization in universities. The Faculty in the Department of Theoretical Physics at Maynooth provides a good illustration. It includes seven people, only two of whom were born in Ireland. The others were born in the Netherlands, Norway, Czech Republic, USA and UK. The blog post says there are two reasons why universities are so international: specialization and diversification. Both of these do apply, but there is a third reason, which concerns personal life, love, the pursuit of happiness, politics, and so on. I gave my reasons for moving to Ireland here.

The personal dimension shouldn’t be ignored, though it is much more complex than the others. Academics are people after all.

4gravitons's avatar4 gravitons

Worldwide, only about one in thirty people live in a different country from where they were born. Wander onto a university campus, though, and you may get a different impression. The bigger the university and the stronger its research, the more international its employees become. You’ll see international PhD students, international professors, and especially international temporary researchers like postdocs.

I’ve met quite a few people who are surprised by this. I hear the same question again and again, from curious Danes at outreach events to a tired border guard in the pre-clearance area of the Toronto airport: why are you, an American, working here?

It’s not, on the face of it, an unreasonable question. Moving internationally is hard and expensive. You may have to take your possessions across the ocean, learn new languages and customs, and navigate an unfamiliar bureaucracy. You begin as a temporary resident, not…

Tá mé sa bhaile – Biden’s Irish

Posted in Irish Language, Politics with tags , , , , , , on April 14, 2023 by telescoper

TRIGGER WARNING: CONTAINS PRONOUNS!

Yesterday, President of the United States of America, Joe Biden, addressed a joint sitting of the houses of Oireachtas in Dublin. Predictably he included an attempt at Irish in his speech to the obvious appreciation of those attending. I was a bit confused by the way what he said was reported in the Irish media, however, e.g.

My confusion was that I didn’t think he said tá mé seo abhaile as widely reported. For one thing, even I as a beginner could see that phrase means “I am this home”, which doesn’t make any sense (not to me, anyway). There are various possibilities for what Joe Biden did say. For what it’s worth I thought it was tá mé sa bhaile which, loosely, means “I am at home”. I note that the news media have generally changed their accounts (e.g. here) to reflect this, although other forms of words are possible. I’m not surprised that Biden struggled with the pronunciation – most of us beginners do, but I think the writers and editors of the newspapers above might at least have corrected his grammar.

The phrase illustrates a couple of interesting curiosities about the Irish language. Expressing the verb “to be” in Irish isn’t as straightforward as it is English. There are two grammatically distinct ways of doing this. The two Irish forms are , which is like the English verb “to be” and the so-called copula, is, which is sometimes called a defective verb. It’s admittedly a bit confusing that the copula looks like the third-person singular of the verb “to be” in English, but there you go.

Going back to, it is frequently referred to as tá (its present tense form as in the phrase above). It can be fully conjugated in all tenses and persons but it is highly irregular. Grammatically, is also just like any other verb, coming first in the sentence, followed by a subject (either a separate noun or pronoun or a suffix, depending on the tense and person, as shown in the conjugations), and then its predicate and any remaining adverbial information. Thus tá mé is “I am” with the pronoun . The accents (síneadh fada)  mean that this is pronounced taw-may.

The copula, however, is not fully conjugated for different subjects, which are always expressed by separate nouns or pronouns, and it only has two forms for different tenses: is can be used for present or future meaning, and ba (with lenition) is used for past or conditional meanings.

Among the specific situations in which the copular is must be used instead of but the main one is to be followed by a noun. You can’t say “I am a Professor” using – it has to be Is Ollamh – but to say “I am old” it is Tá mé sean.

One final remark. If you’re scared of pronouns please look away now. There are over 120 different pronouns in the Irish language. There’s a special version of the pronoun written mise which has two uses that I am aware of. One is when the copular is used for identification – so “I am Peter” is Is mise Peadar – and the other is for emphasis, when it is roughly equivalent to “myself” in English.

P.S. The Irish word for “pedantry” is pedantraí
