Autumnal Equinox 2022

Posted in Biographical, Maynooth, The Universe and Stuff with tags on September 22, 2022 by telescoper

It’s almost that time of year again. The Autumnal Equinox (in the Northern hemisphere) takes place in the early hours of tomorrow morning (Friday 23nd September 2022)  at 02.04 Irish Summer Time (01.04 UT). That is way past my bedtime so I thought I’d post this a few hours early.

Although  the term `equinox’  refers to a situation in which day and night are of equal length, which implies that it’s a day rather than a specific time, the astronomical equinox is more accurately defined by a specific event, i.e. when the plane defined by Earth’s equator passes through the centre of the Sun’s disk (or, if you prefer, when the centre of the Sun passes through the plane defined by Earth’s equator). Day and night are not necessarily exactly equal on the equinox, but they’re the closest they get. From now on days in the Northern hemisphere will be shorter than nights and they’ll get shorter still until the Winter Solstice on 21st December at 21.48 Irish Time.

Many people take the autumnal equinox to be the end of summer. There is a saying around these parts, however, that `Summer is Summer to Michaelmas Day’ (September 29th), which is not until next week. I must say, though, though it doesn’t feel particularly summery today.

Anyway, this is Welcome Week in Maynooth and we’re due to start teaching first year students next week, on Monday 26th September. It seems to be a bumper year for our intake, with 113 so far registered. That’s more than we’ve had in the 1st year since I arrived here. Returning students commenced on Monday 19th. I already gave my first lecture on Vector Calculus and Fourier Series to this class yesterday; I have another with them tomorrow. We have about the same number of students in Year 2 this year as we had last year.

Second Booster

Posted in Biographical, Covid-19 with tags , , , , on September 22, 2022 by telescoper

Today I took a trip out to Punchestown Racecourse for my second Covid-19 booster jab. The possibility of booking one of these opened up for my age group (55+) a few weeks ago and I booked one straightaway, but I was advised to postpone it because of a mystery ailment. That now having cleared up I decided to have it done today, ahead of the full start of teaching next week. In the meantime the booster process has been opened up to mere youngsters (50+) but it was easy to get an appointment.

As far as I know I have ever caught Covid-19, but I thought it wise not to take any chances with the new influx of students and the possibility of increased infection levels. My first booster was on 15th December 2021, so protection is likely to have waned considerably since then. As you can see, new cases have been falling recently in Ireland but the level of new infections (7-day average around 230 per day) is still quite high:

My previous jabs were at City West so I was a little surprised when I registered for my second booster that I was directed to Punchestown. It’s about the same distance from Maynooth to either venue, though, and when I got to the racecourse it was very quiet and I was in and out within half an hour (half of which was the 15 minute “recovery” period). The racecourse – used for steeplechases – is heaving at the time of the annual Punchestown Festival, but fortunately I didn’t have to dodge either crowds or horses, though it was raining heavily.

This time I had the Pfizer-BioNTech vaccine (“Comirnaty”), same as my two original shots; my first booster was of the Moderna (“SpikeVax”) variety.

I’ll be working from home this afternoon in case of problems (though I didn’t experience any serious issues with previous jabs). My next lecture is at 11am tomorrow (Friday) so I should be fine by then even if I experience any side-effects this afternoon.

Michaelmas Memories

Posted in Biographical, Education, Maynooth on September 21, 2022 by telescoper

Yesterday I gave my first lecture of the new academic year. It was the first lecture of the second-year Mathematical Methods module I’ve been teaching for several years now, and was about partial differentiation. Because of the late Leaving Certificate results this year, first-year students don’t officially start until next week but we have some doing my second module and most of them actually came to my first lecture. For most of the new arrivals this week is Welcome Week, with a variety of events – both social and administrative – to help them settle into student life before they start their education proper next week.

As often seems to be the case in late September, the weather is very nice today. The Welsh phrase Haf Bach Mihangel (Michael’s Little Summer) refers to this kind of spell. St Michael is also the origin of the term Michaelmas, which is the name of the Autumn term at Cambridge University. Michaelmas Day itself is on 29th September.

This all takes me back to when I myself left home to go to University in 1982, as thousands of fledgling students are doing in their turn right now.

I started my journey by getting on a train at Newcastle Central station with my bags of books and clothes. I said goodbye to my parents there. There was never any question of them taking me in the car all the way to Cambridge. It wasn’t practical and I wouldn’t have wanted them to do it anyway. After changing from the Inter City at Peterborough onto a local train, we trundled through the flatness of East Anglia until it reached Cambridge. The weather, at least in my memory, was exactly like today. It suddenly struck me this week that that was 40 years ago.

I don’t remember much about the actual journey on the train, but I must have felt a mixture of fear and excitement. Nobody in my family had ever been to University before, let alone to Cambridge. Come to think of it, nobody from my family has done so since either. I was a bit worried about whether the course I would take in Natural Sciences would turn out to be very difficult, but I think my main concern was how I would fit in generally.

I had been working between leaving school and starting my undergraduate course, so I had some money in the bank and I was also to receive a full grant. I wasn’t really that worried about cash. But I hadn’t come from a posh family and didn’t really know the form. I didn’t have much experience of life outside the North East either. I’d been to London only once before going to Cambridge, and had never been abroad.

I didn’t have any posh clothes, a deficiency I thought would immediately mark me as an outsider. I had always been grateful for having to wear a school uniform (which was bought with vouchers from the Council) because it meant that I dressed the same as the other kids at school, most of whom came from much wealthier families. But this turned out not to matter at all. Regardless of their family background, students were generally a mixture of shabby and fashionable, just like they are today. Physics students in particular didn’t even bother with the fashionable bit. Although I didn’t have a proper dinner jacket for the Matriculation Dinner, held for all the new undergraduates, nobody said anything about my dark suit which I was told would be acceptable as long as it was a “lounge suit”. Whatever that is.

Taking a taxi from the station, I finally arrived at Magdalene College. I waited outside, a bundle of nerves, before entering the Porter’s Lodge and starting my life as a student. My name was found and ticked off and a key issued for my room in the Lutyen’s building. It turned out to be a large room, with a kind of screen that could be pulled across to divide the room into two, although I never actually used this contraption. There was a single bed and a kind of cupboard containing a sink and a mirror in the bit that could be hidden by the screen. The rest of the room contained a sofa, a table, a desk, and various chairs, all of them quite old but solidly made. Outside my  room, on the landing, was the gyp room, a kind of small kitchen, where I was to make countless cups of tea over the following months, although I never actually cooked anything there.

I struggled in with my bags and sat on the bed. It wasn’t at all like I had imagined. I realised that no amount of imagining would ever really have prepared me for what was going to happen at University.

I  stared at my luggage. I suddenly felt like I had landed in a strange foreign land where I didn’t know anyone, and couldn’t remember why I had gone there or what I was supposed to be doing. One thing I certainly didn’t think then was that 40 years on I’d still be wondering what I’m going to do when I leave University…

Maynooth University Library Cat Update

Breakfast

Deciding to make my way to work this morning via the South Campus for a change I stumbled across Maynooth University Library Cat and was able to see to his breakfast needs. He emptied the dish and then went for a nap. With a large number of new students on campus these days our famous feline has greatly increased opportunities for interaction (i.e. cadging food). I am reliably informed that he has had at least two other meals today. I don’t know where he puts it all…

R.I.P. Maarten Schmidt (1929-2022)

Posted in History, R.I.P., The Universe and Stuff with tags , on September 20, 2022 by telescoper

Once again I find myself having to pass on some sad news. Astronomer Maarten Schmidt has passed away at the age of 92. The highlight of his long and distinguished career was the discovery, in 1963, that quasars showed hydrogen emission lines that revealed them to be at cosmological redshifts. Together with Donald Lynden-Bell (who passed away in 2018), Schmidt was awarded the inaugural Kavli Prize for Astrophysics in 2008.

Rest in peace, Maarten Schmidt (1929-2022).

Accreditation, Validation and Recognition of Physics Degrees

Posted in Biographical, Maynooth with tags , , , , , on September 19, 2022 by telescoper

Last week I gave a couple of talks to new undergraduate students about courses in Theoretical and Mathematical Physics here at Maynooth. As happens from time to time, a student asked me if our programmes are accredited by the Institute of Physics. The short answer to this is ‘no’.

Before going further into this, I should probably explain what accreditation actually means. An accredited degree is one that counts as a professional qualification that enables the holder to pursue a career in a given discipline, usually as a practitioner of some sort. Obvious examples are medical degrees (which Maynooth does not offer), Engineering, Architecture, Law, Accounting and Psychology (for its clinical aspects). Most degree progammes at Maynooth and elsewhere are not accredited

As the Complete University Guide says:

You shouldn’t be concerned about the quality of a course just because it isn’t accredited  not all degree courses are. Accredited courses are only really necessary if there is a professional qualification in the industry you plan to work in  where they can help you to get ahead in your chosen career.

I’ll add for those who weren’t aware that the Institute of Physics covers the UK and Ireland.

Having a physics degree accredited by the IOP is not a professional requirement as it is in, say, Law or Engineering. Indeed, there is no job or career path in physics that requires a degree with IOP accreditation. If there were then nobody with a physics degree from outside the UK or Ireland would be eligible for it. IOP accreditation is also irrelevant for doing a Masters or PhD. Ask any one of a number of our graduates!

We have discussed IOP accreditation a number of times with the unanimous result that we should steer clear of this process. There are two main reasons why.

The first is that the IOP insists on there being a practical laboratory component of any courses it accredits, so it will not accredit a purely theoretical degree programme. There is, for example, a Theoretical Physics degree programme which is accredited, but students on this programme had to do laboratories in the first year. Here in Maynooth the Department of Experimental Physics has accreditation for programmes, including a Double Major in Experimental Physics and Another Subject. Consequently, if you do Experimental Physics and Mathematical Physics that combination is accredited. But if you do Mathematical Physics on its own or with another subject that will not be an accredited programme. So the first reason is that if we applied for IOP accreditation (which we have never done and have no intention of doing), we would not get it unless we required students to take Experimental Physics too, which would reduce the choice available to students.

As an aside I should mention that there is an alternative degree status offered by the IOP, namely recognised rather than accredited. A list of current recognised courses is here (PDF). This includes interdisciplinary programmes involving mathematics and physics. We could apply for this, I suppose, were it not for the second point.

The second point is that we think it would be a huge waste of effort, especially for a very small department like ours. While the accreditation process does provide some external oversight of course content and quality, one has to weigh up the small benefit against the extremely onerous bureaucratic burden it places on departments as well as imposing restrictions on progression rules and forcing an unjustifiable conformity on courses.

We in the Department of Theoretical Physics at Maynooth University feel these negatives strongly outweigh any positives of accreditation, which we feel are in fact very hard to identify. There is no job or career path in physics that requires a degree with IOP accreditation. If there were then nobody with a physics degree from outside the UK or Ireland would be eligible. IOP accreditation is also irrelevant for doing a Masters or PhD.  I repeat that we have never to my knowledge had any problem with lack of IOP accreditation being a barrier for any of our graduates.

That doesn’t mean there are no quality controls on our programmes. We go through regular institutional quality reviews that undertake a rigorous assessment of our courses, including interviewing students and staff. The panel on our last review included distinguished physicists from institutions outside Ireland and the UK. We obtained very high commendations for our courses through this process as well as some suggestions of things we might consider to improve things still further. I think such processes that validate our programmes are at least as rigorous as IOP accreditation and are significantly less Anglocentric.

As a Fellow of the Institute of Physics who has taught in Physics Departments for over 20 years I have never understood why people think IOP accreditation is at all important. I know many physicists feel otherwise, however, and indeed most physics courses in the UK and Ireland do appear on the list. I would argue that this is largely for fear of appearing to be out of line rather than for any positive reason.

Anyway, feel free to air your own views through the box below!

Strategic Plans

Posted in Biographical, Education, Maynooth with tags , , on September 18, 2022 by telescoper

Maynooth University is in the middle a consultation exercise involving the construction a new Strategic Plan Envisioning Our Future for the period 2023-28. This is something higher education institutions do from time to time, and it usually involves dreaming up ways of spending money they haven’t got on things they don’t need. I’ve seen a few Strategic Plans in my time, but yet to see one that was worth the glossy paper it was expensively printed on. I can’t envision this one being any different,

You could dismiss the current Strategic Plan as merely an irrelevance but it is having a real effect, in that it has completed distracted the University management away from crucial operational matters, such as new appointments and fixing various failing systems. Moreover, it seems very likely, there being little chance of a substantial increase in government funding, that any new “initiatives” arising from the Strategic Plan will be paid for by further plundering already hard-pressed departmental budgets.

The other day I looked up “Strategy” in a dictionary and found

Noun: a plan of action designed to achieve a long-term or overall aim.

The biggest issue is not the plan of action bit, it’s the articulation of the aim and the interpretation of long-term as being “the next five years”. I know I am excessively old-fashioned but I think a university – especially a publicly funded one – should be aiming to be as good as possible at teaching and research. If we have to have a plan for the next five years, at a bare minimum it should involve increasing the investment in its existing departments and providing better teaching facilities. I don’t see either of those happening at all. We’ve got a new teaching building, but nothing has been done to improve any of the other teaching rooms on campus. It’s very dispiriting for front-line academic staff to appearance such neglect of what should be the core functions of the institution.

Anyway, now that I am no longer Head of Department and free of the requirement to attend pointless meeting after pointless meeting I am going to focus what remains of my energy on teaching and research, even if The Management does not deem these important.

Tomorrow (19th September) is the first week of teaching term for the 2022-23. Though new students don’t officially start until 26th September, some are already here and I have even spoken to them. Although we have had a very rough couple of years, our first-year numbers look healthy, which is a good point to be handing over the reins. I have two new PhD student and one Research Masters student arriving this academic year which should help me with my research plans.

Undergraduate science degrees and PhD degrees in Maynooth are typically of four years’ duration. I’ll be sixty during this academic year and over the last few weeks I have been doing a bit of strategic planning of my own. Although I can’t be made to retire until I’m 70, I think it will be a good time to go when the incoming UG & PG cohort finishes, i.e. four years from now. I love teaching and enjoy my research but there is a point at which one should step aside and make way for someone younger.

Assuming, that is, that: (a) I live that long; (b) I can sell my old house and pay off my mortgage; (c) my USS pension is not worthless by then; (d) I’m not sacked in the meantime for insubordination.

Why you shouldn’t pay by Direct Debit

Posted in Biographical, Cardiff with tags , on September 17, 2022 by telescoper

When I visited Cardiff recently one of the things I did was read the electricity and gas meters (and take photographs of both as proof of the accuracy of the readings. It was only when logged onto the SSE website to enter the numbers that I realised a bill had already been issued (on 1st September) for the amount above.

I know gas has got more expensive, but really…

The bill above is based on an ESTIMATED reading for three months in the summer for an empty house. The energy company know that the house is unoccupied but nevertheless chose to produce an estimate of the amount of gas used that is orders of magnitude higher than any amount I have ever used there, even when the house was occupied in the depths of winter. The reading I took shows that the amount of gas used since the last reading was minimal. I uploaded the reading as soon as I could but am yet to receive a corrected bill.

Why they have come up with such a ridiculous figure is beyond me, but it did make me glad that I don’t pay this bill by direct debit. If I did so I would have been charged automatically which would have emptied my bank account (and more) and caused all kinds of problem with payments for other services.

Fourteen Years In The Dark

Posted in Biographical with tags , on September 16, 2022 by telescoper

When I logged onto WordPress yesterday I received a message that it was the 14th anniversary of my registration with them, which is when I took my first step into the blogosphere; that was way back on 15th September 2008.

I actually wrote my first post on the day I registered but unfortunately I didn’t really know what I was doing on my first day at blogging – no change there, then – and I didn’t actually manage to figure out how to publish this earth-shattering piece. It was only after I’d written my second post that I realized that the first one wasn’t actually visible to the general public because I hadn’t pressed the right buttons, so the two appear in the wrong order in my archive.

Such was the inauspicious beginning of this “shitty wordpress blog”!

If you’re interested in statistics then, as of 9.00am Irish Summer Time  today, I have published 6060 blog posts posts and have received a total of 4.99 million hits; I expect to pass the 5M mark sometime next week. The largest number of hits I have received in a single day is still 8,864 (at the peak of the BICEP2 controversy).

The last 14 years have been eventful, to say the least, both personally and professionally. I started blogging not long after I’d moved into my house in Pontcanna, Cardiff. Since then I moved to Sussex, then back to Cardiff, and then to Ireland. The last couple of years have been dominated by the Covid-19 pandemic.

Scientifically we’ve seen the discovery of the Higgs Boson and gravitational waves, both of which resulted in Nobel Prizes, as did the studies of high-redshift supernovae. The Planck mission mission was launched, did its stuff, and came to a conclusion in this time too. Most recently we have had the launch of JWST and have started to see the first science results. Science at least has moved forward, even many other things have not.

Last night’s fireball was a meteor

Posted in The Universe and Stuff with tags , , on September 15, 2022 by telescoper

I didn’t see it myself but there were hundreds of reports last night of a very bright fireball over Ireland and the UK at around 9pm. Here is an example video of the phenomenon:

Quite a few people have asked me today what this object, most people assuming that it was space junk coming back down to Earth. I gave the most accurate answer possible which is that I didn’t know, but I thought that to be that bright it would have to be quite large and if it were that large a bit of space debris we would (a) know what it was and (b) it seemed to me that it would probably have broken up a bit more. While that seemed to rule out, e.g. a rogue bit of one of Elon Musk’s constellations , I am not an expert and thought I could well be wrong.

Anyway, the Jury has now returned to deliver a verdict. After collating and cross-referencing all the reports from tracking stations, the UK Meteor Observation Network is now 100% convinced that it was a meteor (rather than space debris). Its trajectory took it in a roughly north-westerly direction, passing directly over Belfast, and it came down in the Atlantic somewhere near the Hebrides.

There is enough data about this object to infer its orbit of the asteroid of which it was originally part: Semi-major axis 1.36A.U., eccentricity 0.33, inclination 8.77°, Period 1.59Y, LA Sun 171.72°, last Perihelion 2021-03-24.

All the relevant data can be downloaded here.

I hope this clarifies the situation.
