So here we are once again on LGBTQ+ STEM Day! Last year on this day I gave a talk via Zoom and remember hoping that the following year we could have an in-person event in Maynooth but alas that was not to be. Nevertheless I can at least use the medium of this blog to wish all LGBTQ+ persons working in STEM subjects around the globe a very enjoyable day. You can find out about events near you by checking here, looking for the hashtag #LGBTQSTEMDay on social media or by following the twitter account:

Posted in Biographical with tags Faces, radio, Voices on November 17, 2021 by telescoperRegular readers of this blog will know that I listen to the radio much more often than I watch the TV. In fact I was thinking last night that I might make the forthcoming Christmas break entirely television-free, to give me a chance to catch up on reading and listen to music when I’m not drinking wine or cooking and eating food.
Anyway, I was listening to the radio last night and it struck me that whenever I hear the voice of someone whose face I have never seen my brain seems to construct a to want to construct a mental image of what the person looks like. This not only happens when listening to the radio but also when talking to someone on the phone. It seems an automatic process over which I have no conscious control. If and when I subsequently find out what the person actually does look like they’re rarely anything like I’d imagined, so whatever process goes on in my head is not very accurate!
But what is the process?
My theory – for which I have absolutely no evidence – is that my brain kind of runs through my memory bank of voices and the faces that go with them, tries to find the closest matches to the voice I’m hearing, and then constructs an image as a kind of amalgam of those identified. The assumption would be that people who sound the same might tend to look the same, which is obviously more than a little dodgy.
Obviously there is contextual information too. Gender and race and age influence the process, for example, but there are many other factors. If I hear the voice of someone on the radio who is introduced as, say, an opera singer my brain probably try to find a match among the faces of opera singers I have seen, and so on.
I’d be interested to know if anyone shares this experience of trying to put a face to the voice and what is going on in the brain when it happens!
As a related issue I remember a discussion in a pub a while ago – back in the days when I used to have discussions with people in pubs – about faces. Some people are considered have more attractive faces than others (an entirely subjective statement) but there’s something about certain faces that makes the owner of the face appear kind as opposed to being beautiful or handsome or otherwise attractive.
People with kind faces appear to be friendly and sympathetic and, by implication, more approachable, which encourages other people to talk to them in a way that they probably would not talk to others. This is not always a positive move. I remember a female colleague in Cardiff – who is aware that she does have such a kind of kind face – telling me that she often got a bit fed up with other colleagues unburdening themselves in conversation with her about things she’d rather not know about.
Anyway I know quite a few people that I would say have kind faces but I don’t know what it is that makes them appear so. It may be something about the shape of the face, softer features, the eyes….or what?
So Question 2 for today’s discussion is: what makes a face look kind?
Half Measures
Posted in Biographical, Covid-19, Education, Maynooth with tags Coronavius, Maynooth University, SARS-Cov2 on November 16, 2021 by telescoperAgainst the backdrop of rapidly rising numbers of Covid-19 cases the Irish Government today announced the return of some restrictions, including the closure of hospitality venues no later than midnight and a return to working from home “unless absolutely necessary”. On the latter, however, it has said that “There will be no reintroduction of remote learning for schools and third-level institutions at this point”.
I think the key phrase is “at this point”. I don’t think the new measures go nearly far enough and they will have to be revisited in a week or two, at which point we will revert to remote (online) teaching. Although we haven’t been give guidance yet, I think we’ll be carrying on with in-person lectures and tutorials at Maynooth for the time being, but it’s no more than an even money bet that we’ll stay that way until the end of term. I would also suggest that the odds are very much against us actually having examinations on campus in January. We await further guidance from the University about this, so I don’t know. The timetable for the January examinations is due to be published next week so a decision will have to be made very quickly.
What I do know, though, is that my second vaccine dose was on June 8th. The Government has now announced that 50-59 year olds (which includes me) can now get a third (booster) dose six months from their last one. In my case that is December 8th. But the roll-out of boosters has been painfully slow in Ireland, and most of the over-60s haven’t had theirs yet. It’s likely to be weeks or months until I get an appointment for mine.
We might have to switch to remote teaching in a while anyway if the rules are changed but I have made the decision that if I haven’t got my booster by December 8th I’ll be working from home and switching all my lectures online. Term ends on December 17th so I’ll only have to give a few remote lectures, but for me it is a matter of principle.
By deciding that in person teaching is “absolutely essential” the Government has admitted that lecturers are frontline staff and we should accordingly get a booster dose at the appropriate time. I’ve worked countless hours of unpaid overtime during this pandemic and I’m not going to continue without adequate protection from infection.

Worrying Times…
Posted in Biographical, Covid-19, Education, Maynooth with tags Coronavirus, Covid-19, Private Eye, SARS-Cov2 on November 14, 2021 by telescoperSo here I am, trying to plan my teaching for next week and wondering what’s going to happen between now and the end of term. Here at Maynooth University lectures finish on 17th December, five weeks from now. I’m just about on schedule to cover everything I’m supposed to, so I’m not worried about that.
What I am worried about is that Covid-19 cases are continuing to climb. The latest 7-day rolling average of new cases is over 3900 per day and the increasing trend show no sign of slowing down. It will reach the 5000 mark in a week or two. Some daily figures have already passed that milestone. The death rate is still relatively low – 74 Covid-19 related deaths were recorded in the last week – but is edging up; over a hundred people with Covid-19 are being treated in ICU as of today.
The Irish Government seems to have no intention of introducing effective countermeasures and is instead just advising people to cut down the amount of socializing they do. I don’t think that will work. It seems very clear to me that the Government lost the room many weeks ago by frequently implying that the Covid-19 pandemic was over. They then caved in to the hospitality industry by allowing nightclubs to open. It is no doubt in such places that the virus is spreading. The Government keep stating that they are concerned but do nothing, blinking at the onrushing disaster like rabbits caught in the headlights of an approaching car.
Case numbers on campus at Maynooth remain fairly low, though the latest figure (69) is almost double last week’s figure (35). Students in my classes continue to wear face coverings and observe the other protocols and all the signs are that lecture halls and labs are pretty safe environments but we have no say in what happens off campus. As well as being concerned for the health of students and staff, I have particular worries about my Department. We’ve been short-staffed since the start of term and simply have no spare effort to provide cover for lectures or tutorials if anyone becomes sick.
The Irish Health Service is under extreme pressure and the delivery of booster shots is being rolled out very slowly. I had my second Pfizer dose in June so should get a third shot in December but it is not clear that I will. I’m not going anywhere at Christmas anyway so that’s not a big deal but I’m worried by the broader picture. A cartoon in a recent issue of Private Eye is very apt:
Might we have to switch our lectures back online again before Christmas? Might our examinations be online again in January? Who knows. We’ll just have to wait and see but I think the blackboard in my study might be back in use very soon.
Pithecanthropus Erectus – Charles Mingus
Posted in Jazz with tags Charles Mingus, Pithecanthropus Erectus on November 13, 2021 by telescoperI heard this track on the radio the other night courtesy of John Kelly’s show and thought I’d write a post about it because I think it’s a neglected masterpiece. Pithecanthropus Erectus is the title track of an album by Charles Mingus released in 1956. For that time it was incredibly new: the long passages of static harmony, along with grunts and squeals from the horns, all became common place in avant garde jazz in later years but it is very surprising to hear them in a record from the mid 50s.
Mingus intended this piece to convey in music humanity’s evolution, which he imagined would end in violent destruction. Who’s to say he was wrong? The tune itself is in an intriguing ABAC form with the B and C sections based on the same unvarying harmonic pattern but the C section being agitated and even chaotic. On the first and last choruses the alto sax of Jackie Mclean and the tenor of J.R. Monterose play improvised duets on the B section while the C section involves the whole band improvising collectively in a style reminiscent of the free jazz of the 1960s. The unusual accents on the fourth beat of the bar were later adopted by Miles Davis on Milesetones. These are just a couple of examples of how influential this track was to turn out to be. Looking back on it in historical perspective you can see how much of the musical vocabulary of jazz expanded with this one track.
Mingus shared with Miles Davis the ability to create music that was distinctively his own while somehow at the same time giving his musicians plenty of time to express themselves. In this performance there’s a very fine piano solo by Mal Waldron who, among other things, very effectively channels Thelonious Monk to a marvelous bass accompaniment by Mingus.
The other three tracks on the album are good too, but inevitably pale beside this work of genius in which Mingus managed to weld all these new and untried elements into a completely satisfying unity that was years ahead of its time.
That Was The Masterclass That Was
Posted in Education, Maynooth, The Universe and Stuff with tags Astrophysics, Cosmology, Masterclass, Maynooth University on November 12, 2021 by telescoperThis morning we did the Astrophysics and Cosmology Masterclass advertised here. I think it went quite well. Apparently we had over sixty schools registered – at least one in every County – about a 1,000 schoolkids altogether. Certainly there were lots and lots of questions, which is a good sign!
Here is a screen grab of part of the event. I didn’t realize my camera was a bit wonky!
In case anyone is interested here are the slides I used for my part of the talk:
I’ll post a recording of the whole event when it becomes available. Here is the recording of the workshop:
I had to leave before the end to go to a vector calculus lecture that was interrupted by the arrival of the Power Rangers, but that’s a different story…
Unsolved, by John McCrae
Posted in History, Poetry with tags John McCrae, Poems, Poetry, Remembrance Day, Unsolved on November 11, 2021 by telescoperThe poet John McCrae served with distinction in the Canadian Field Artillery during the First World War, rising to the rank of Lieutenant Colonel. He died in 1918, of pneumonia, shortly before the end of the conflict.
McCrae is best known for writing the poem In Flanders Fields, the imagery of which led to the adoption of the poppy as the emblem of Remembrance Day (11th November i.e. today). He wrote many other interesting poems, however, so I thought I’d share one here to celebrate his life.
Amid my books I lived the hurrying years,
Disdaining kinship with my fellow man;
Alike to me were human smiles and tears,
I cared not whither Earth’s great life-stream ran,
Till as I knelt before my mouldered shrine,
God made me look into a woman’s eyes;
And I, who thought all earthly wisdom mine,
Knew in a moment that the eternal skies
Were measured but in inches, to the quest
That lay before me in that mystic gaze.
“Surely I have been errant; it is best
That I should tread, with men their human ways.”
God took the teacher, ere the task was learned,
And to my lonely books again I turned.
by John McCrae (1872-1918)
Please don’t call me “Sir”!
Posted in Biographical, Education, Maynooth on November 10, 2021 by telescoperYesterday, on the way out of the lecture theatre after finishing a class, I was chatting with some of the students therein and the subject came up of how they should address me (and their lecturers in general).
One thing I’ve noticed since moving to Ireland is that, more so in England or Wales, first-year students often call me “Sir” if they want to attract my attention to something such as – to give a purely hypothetical example – a missing minus sign in a calculation. I suppose that me something to do with more of the schools perhaps being run on more traditional lines than in the UK.
For completeness I should point out that I went to an old-fashioned grammar school at which all the teachers were called “Sir” as they were all male. Some teachers were unbearably pompous in their insistence on that form of address, which is probably why I dislike it so much although I do appreciate the attempt to be polite.
I can understand why students – at least initially – carry on at university with behaviours that were deemed appropriate at school, but to my mind universities are really different because everyone is an adult. Of course I’m supposed to know more about the stuff that I’m teaching than the student, but the aim of the education is to eradicate that difference as effectively as possible. I think an important step on that journey is for the students to feel part of a joint venture than being talked at by some sort of authority figure. Formal titles do not encourage students to ask questions, which is an essential part of the teaching process.
Anyway, when a student asked me if he should call me “Sir” I said “No. Please don’t!”
“What should I call you then?”, he asked. “Professor?”
“My name is Peter, so that’s what you should call me” I replied. The student seemed quite shocked at the level of informality implied, but as far as I know I think all the teaching staff in the Department of Theoretical Physics are all comfortable with first-name terms.
I’ve never really thought about this before so I wonder what other university teachers think. Do any of you out there insist on using formal titles or is informality the norm?
