A Free Online Course in Cosmology from SISSA

Posted in Education, The Universe and Stuff with tags , , , , on November 25, 2021 by telescoper

The nice people at the Scuola Internazionale Superiore di Studi Avanzati (known to its friends as SISSA for short) have made available a free online course in cosmology. You can get all of it on Youtube.

The course comprises 16 professionally edited video-lectures delivered by lecturers of the SISSA Astrophysical and Cosmology and Astroparticle PhD Programs and some of their collaborators. I know some of the participants personally, including Paulo Salucci (who introduces the course though I haven’t met him in person for ages so it was nice to see him on camera.

Cosmology is a big subject, of course, and a short-ish course can’t cover everything so there is an emphasis on the research topics covered by SISSA scientists. I haven’t watched all the videos but those I have seen are pretty good. There are actually 17 videos in the playlist below but that includes a very short prelude to introduce the series. The others are between about 25 and 45 minutes in length so you probably don’t want to watch them all in one sitting!

Peppa Pig: An Apology

Offensive Item

I have over many years been using the item shown above in lectures to demonstrate the properties of spherical surfaces, for example in situations involving vector calculus and in astrophysics. Given recent events, however, I realize that my use of this specific object may cause offence through the possibility that it may be construed as an endorsement of the views of the UK Prime Minister. I would therefore like to make it clear that no such endorsement should be inferred, that I have never visited Peppa Pig World, and that I did not play any part in the writing of Mr Johnson’s speech to the Confederation of British Idiots earlier this week.

I can also confirm that I have now disposed of the above item in an authorised refuse and recycling centre.

I hope this clarifies the situation.

Questions of Examinations and Lectures

Posted in Covid-19, Education, Maynooth with tags , , , , on November 20, 2021 by telescoper

The deterioration of the Covid-19 situation in Ireland continues apace, with a 7-day average of new cases currently around 4300 per day and 640 people in hospital with 121 needing intensive care.

No doubt due to vaccination the number of deaths remains mercifully low, just 43 reported last week. Let’s hope that lasts.

We have four more weeks of teaching at Maynooth University this semester after which we have the Christmas break and then, in January, the examination period. The current plan is for the examinations to be of the traditional kind, taken in an exam hall on campus but how long this will indeed be the plan is anyone’s guess.

Here at Maynooth we have been told here that a decision will be taken next Friday (26th November) on whether on-campus examinations will go ahead after Christmas. With just three weeks of the term left at that point, this seems very late. If the decision is taken next week to go ahead and the pandemic continues to deteriorate (which is likely, with a surge in transmission expected over the holiday) then that decision may have to be reversed in January.

The Minister responsible for Higher Education, Simon Harris, has indicated that third-level institutions may have to introduce special mechanisms to help students prevented from attending exams in person by Covid-19.

I really hope this is not going to be interpreted as meaning that we have to offer both online and on campus examinations.

That’s partly because of the workload issue: we’ve already written our examinations on the basis that they will be held in person and would have to write another set and get them ready with just three weeks of the term left. We’ve been landed with heavy increases in workload at short notice before I don’t think I’m the only person to be a bit fed with it. Another issue, is that is fairness. I think it is important that all students should take the same examination in the same way otherwise one group might be disadvantaged relative to the other. It would be fairer simply to allow students who can’t take the on-campus examinations in January to take the August repeat in the usual manner.

It’s not for me to decide, of course, but I think it would be sensible to take the decision immediately to switch to online examinations in January. That way staff and students will know straight away where they stand. If it turns out the pandemic does go as badly over the next two months then this might seem to have been excessively cautious, but what would really be lost? We have done three examination periods online now during the pandemic and I think that by now we know how to do it reasonably well.

Examinations are still some time in the future of course, but we still have four weeks of teaching to get through. I have seen anecdotal evidence from colleagues that attendance at lectures and tutorials has fallen rapidly since the mid-term break. I have heard directly from some students that they do not feel safe travelling to and from University and are wary of the large crowds on campus.

My own experience is that lecture attendance has held up reasonably well in my modules, but I deliver my lectures as webcasts and record them anyway so am quite happy if students want to watch them remotely or offline at a subsequent date. Many of them are taking other subjects which are taught in bigger classes which are all online anyway and in that case there is little incentive to come onto campus for one module when everything else is remote.

Simon Harris seems to have nailed his colours to the “return-to-campus” mast so even if there is a drastic surge in Covid-19 over the next few weeks I think the official line will be that we carry on teaching in person. Students however are probably more sensible that either politicians or University managers and will revert to online learning for all practical purposes by simply not coming to campus. And who could blame them?

The Hardest Problem

Posted in Cute Problems, Education, mathematics with tags , , , on November 19, 2021 by telescoper

The following Question, 16(b), is deemed to have been the hardest problem on the Maths Extension 2 paper of this year’s HSC (Higher School Certificate), which I think is the Australian Equivalent of the Leaving Certificate. You might find a question like this in the Applied Mathematics paper in the Leaving Certificate actually. Since it covers topics I’ve been teaching here in Maynooth for first-year students I thought I’d share it here.

I don’t think it’s all that hard really, probably because it’s really a physics problem (which I am supposed to know how to solve), but it does cover topics that tend to be treated separately in school maths (vectors and mechanics) which may be the reason it was found to be difficult.

Anyway, answers through the comments box please. Your time starts now.

Half Measures

Posted in Biographical, Covid-19, Education, Maynooth with tags , , on November 16, 2021 by telescoper

Against 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.

Astrophysics & Cosmology Masterclass – The Video!

Worrying Times…

Posted in Biographical, Covid-19, Education, Maynooth with tags , , , on November 14, 2021 by telescoper

So 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.

That Was The Masterclass That Was

Posted in Education, Maynooth, The Universe and Stuff with tags , , , on November 12, 2021 by telescoper

This 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…

Please don’t call me “Sir”!

Posted in Biographical, Education, Maynooth on November 10, 2021 by telescoper

Yesterday, 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?

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…
