An O-Level History Examination from 1979

Posted in Biographical, Education, History with tags , , , , on April 18, 2018 by telescoper

I have in the past posted a few examples of the O- and A-level examinations I took when I was at school. These have been mainly science and mathematics papers as those are relevant to the area of higher education in which I work, and I thought they might be of interest to students past and present.

A few people have emailed me recently to ask if I could share any other examinations, so here are the two History papers I took for O-level in June/July 1979. Can that really have been almost 40 years ago?

These were Papers 5 and 12 out of an unknown number of possible papers chosen by schools. My school taught us exclusively about British and European history from the mid-19th to early 20th centuries; you will observe that in both cases `history’ was deemed to have ended in 1914. It’s possible that some of the other papers paid more attention to the wider world.

I have no idea what modern GCSE history examinations look like, but I’d be interested in any comments from people who do about the style and content!

Cardiff to Dublin via Belfast

Posted in Biographical, Cardiff with tags , , , on April 11, 2018 by telescoper

I thought I write a brief post to arising from today’s travel difficulties, really just to make a record of the episode for posterity.

As last Wednesday I got up early this morning (4.30am) to get the 7am FlyBe flight from Cardiff to Dublin, due into Dublin at 8.05am. Having only hand luggage, as usual, I proceeded straight upstairs to the departure area only to find that the screen said the flight was cancelled, and directed passengers intending to travel on it back downstairs to the `Disruption Desk’ .

A long queue had already formed by the time I got there, but I got to the desk fairly quickly. The assistant explained that the cancellation was due to `staff sickness’ (i.e. they were short of a pilot) and the only option on offer was to fly to Belfast whence a bus would be provided to Dublin. The Belfast flight should have left at 6.15am but was being held for passengers to Dublin. I was also given a £5 refreshments voucher.

I thought a moment and then decided to accept this offer. I didn’t have any morning appointments today, but definitely had to get to Maynooth somehow by tomorrow morning as I have a lecture to deliver.

The plane left Cardiff about 7.15am and arrived in Belfast around 8.10am but when I emerged from the arrivals area there was no bus. In fact it took about 45 minutes to arrive, and we didn’t get going until about 8.55am. Many of the passengers were clearly nervous about missing connecting flights in Dublin, including a group of women planning onward travel to the USA, but the trip was fairly uneventful apart from the fact that the toilet was out of commission necessitating a stop so that people could use the facilities in a service station.

I can confirm that there is no visible border between Northern Ireland and the Republic on the road between Belfast and Dublin, although it does change name from A1 to M1 on the way. The distance between Belfast and Dublin by road is about 100 miles and it took just over two hours. I arrived at Terminal 1 of Dublin Airport at 11.05, almost exactly three hours late. I thought that wasn’t too bad a result given the chaos in Cardiff when I left but it was still a frustrating morning. I had to wait until 11.50 for the bus to Maynooth, where I finally arrived about 12.40.

I will of course be submitting a request for the compensation to which I am entitled for the delay, but above all I hope that those whose arrangements were even more seriously disrupted than mine managed to get to where they needed to go in the end.

Remembering Clover

Posted in Biographical, Science Politics, The Universe and Stuff with tags , , , , , , , on April 10, 2018 by telescoper

I was tidying up some papers in my desk yesterday and came across a clipping dated April 9th 2009, i.e. exactly nine years ago to the day. Amazed by this coincidence, I resolved to post it on here but was unable to work out how to use the new-fangled scanner in the Data Innovation Institute office so had to wait until I could get expert assistance this morning:

Sorry it’s a bit crumpled, but I guess that demonstrates the authenticity of its provenance.

The full story, as it appeared in the print edition of the Western Mail, can also be found online here. By the way it’s me on the stepladder, pretending to know something about astronomical instrumentation.

I wrote at some length about the background to the cancellation of the Clover experiment here. In a nutshell, however, Clover involved the Universities of Cardiff, Oxford, Cambridge and Manchester and was designed to detect the primordial B-mode signal from its vantage point in Chile. The chance to get involved in a high-profile cosmological experiment was one of the reasons I moved to Cardiff from Nottingham almost a decade ago, and I was looking forward to seeing the data arriving for analysis. Although I’m primarily a theorist, I have some experience in advanced statistical methods that might have been useful in analysing the output. It would have been fun blogging about it too.

Unfortunately, however, none of that happened. Because of its budget crisis, and despite the fact that it had already spent a large amount (£4.5M) on Clover, the Science and Technology Facilities Council (STFC) decided to withdraw the funding needed to complete it (£2.5M) and cancel the experiment. I was very disappointed, but that’s nothing compared to Paolo (shown in the picture) who lost his job as a result of the decision and took his considerable skills and knowledge abroad.

We will never know for sure, but if Clover had gone ahead it might well have detected the same signal found five years later by BICEP2, which was announced in 2014. Working at three different frequencies (95, 150 and 225GHz) Clover would have had a better capability than BICEP2 in distinguishing the primordial signal from contamination from Galactic dust emission (which, as we now know, is the dominant contribution to the BICEP2 result; see thread here), although that still wouldn’t have been easy because of sensitivity issues. As it turned out, the BICEP2 signal turned out to be a false alarm so, looking on the bright side, perhaps at least the members of the Clover team avoided making fools of themselves on TV!

P.S. Note also that I moved to Cardiff in mid-2007, so I had not spent 5 years working on the Clover project by the time it was cancelled as discussed in the newspaper article, but many of my Cardiff colleagues had.

Spring comes to Maynooth

Posted in Biographical, Cardiff, Maynooth with tags , , on April 5, 2018 by telescoper

After a good night’s sleep last night I was up early this morning to give my usual Thursday 9am lecture on Computational Physics. It was a bright sunny morning, though there was overnight frost and a distinct chill in the air, as I made my way to Physics Hall. Once there, for the first time this year, I had to close the blinds because the Sun was shining too bright for the projector screen. It has hitherto always been too gloomy outside for this to happen. The picture above (of St Joseph’s Square, on the South Campus) was taken as I left St Patrick’s House after a very nice lunch of roast lamb in Pugin Hall. By this time of day it was pleasantly warm.

Here’s a nice picture of the Library circulated by the Maynooth social media folk earlier today.

library

Anyway, this mornings’s lecture was an introduction numerical solutions of ordinary differential equations, beginning with Euler’s method applied to initial value problems. Further studies of this topic – which is very important for bidding computational physics – will take up the rest of the lectures as we explore the delights of, e.g. Runge-Kutta codes and boundary value problems. This morning’s lecture was followed this afternoon by a two-hour lab session in which the students had to write their own ODE solver.

Among the advantages (for me) of teaching this module is that I’m actually becoming reasonably competent at Python. At any rate I’ve difficult improved my ability to spot bugs in codes written by other people. In fact, it is traditional for the exam in this module to include a question that involves finding 10 mistakes in a piece of Python code. That’s a fun challenge, the only real problem for me being to write a bit of code with only 10 mistakes in it in the first place…

Talking of exams, the timetables for my two current employers are now out. Computational Physics in Maynooth is on Friday 11th May while Physics of the Early Universe in Cardiff is almost a fortnight later, on Thursday 24th May. The Easter recess is shorter here in Maynooth than in Cardiff, where lectures do not resume until April 16th (assuming the UCU strike does not continue), which is why the exams in Maynooth are earlier. I’m grateful there isn’t a clash. I should have ample time to mark the Maynooth ones before the Cardiff ones are due. After the first week or so of May I won’t have to teach in both institutions, so my somewhat hectic schedule should become a little more relaxed from then onwards.

I mentioned the UCU strike above in passing. The UCU leadership has decided that there will be an online ballot on whether to accept the `offer’ recently made by the management organisation UUK. The ballot will be open until April 13th. If the vote goes against acceptance then Cardiff staff will be back on strike from 16th April, and there will be further industrial action over the examination period. I can’t predict what the result of the ballot will be. Although the UCU leadership is recommending acceptance I don’t know anyone personally who intends to vote for it, but there’s a probably a big selection effect there! There is a distinct possibility that examinations will be badly disrupted not only in Cardiff but all over the UK. It’s a very sad state of affairs but all those on strike (and the majority of students) consider the UUK side to be to blame…

A Time to Resign

Posted in Biographical, Cardiff, Maynooth on April 2, 2018 by telescoper

After a weekend in which I did very little apart from sleeping, eating and doing crosswords, it was time today to get my finger out and start organising for the coming months.

Top of the agenda was writing a letter of resignation from my position at Cardiff University, which I have now done. I’ll hand it in tomorrow. I’ve already told my colleagues there that I was planning to leave this summer, but it’s now time to make it official. After my notice period expires, I will be relocating full-time to Ireland in July.

One of the complications of the resignation process is that I am obliged to use up all my annual leave entitlement before I go. I haven’t taken much this year so I have to sort out how to take it before I go while also ensuring I am still available to carry out my remaining duties and attending meetings that require my presence (eg examiners meetings). I’ll also have to sort out my pension, arrange removal of my office things to Ireland and, finally, return my keys.

When I leave it will only be two years since I went through a similar process at Sussex. I burst into tears on my last day there. I hope I don’t embarrass everyone at Cardiff in a similar way.

My contract at Cardiff was for a fixed term of three years, on a part-time basis. I’ll be leaving a year early, but I think the record will show that I’ve done virtually everything I was brought in to do. In particular the Data Innovation Research Institute has expanded dramatically over the past couple of years and looks set for a bright future, as does the School of Physics & Astronomy in which I am employed for the other half of my time.

When I returned to Cardiff two years ago I had it in my mind to retire when my contract was up but I’m now very excited about the move to Ireland, an opportunity which I hadn’t foreseen at all!

Anyway there’s lots to do in the next few weeks, including my remaining teaching duties in Cardiff and Maynooth, so I’d better get back to it!

P. S. Incidentally, I discovered that one of the readings at Stephen Hawking’s funeral was the beautiful fatalistic passage from Ecclesiastes that begins

For everything there is a season, and a time for every matter under heaven: a time to be born, and a time to die..

That may have influenced the title of this post…

Uncommon Travel Experiences

Posted in Biographical with tags , , on March 29, 2018 by telescoper

Back in Cardiff for the Easter weekend – which I am to spend mainly sleeping – after flying back this morning from Dublin, I thought I’d do a brief post about a fairly strange thing that happened when I got to Cardiff Airport this morning.

I’ve done this flight many times over the past few months and arrival at Cardiff has always been the same story: passengers disembark and walk through a special arrival gate marked `Channel Islands and Republic of Ireland’. This leads past a couple of desks (marked security) which have always been unoccupied and straight into the baggage reclaim area. This morning, however, there were 3-4 police and/or UKBA people and they checked everybody’s passport who was on the flight from Dublin.

This is quite irregular, as there is supposed to be a Common Travel Area including the UK and Ireland (as well as the Channel Islands and the Isle of Man), and passport checks are not routinely made at borders within the CTA. They never have been to date on any of the trips I’ve made.

So what was going on? Was it some sort of rehearsal for the post-Brexit era (which may well see the end of the CTA, as there is likely to be a hard border between the UK and Ireland)?

I suspect not. One possibility is that the Police were actually looking for someone or something specific. Although passport checks are not routinely made, there is no law forbidding them if there’s a reason to make them. In fact the CTA is the result of informal agreements rather than domestic laws or international treaties so it’s not legally enforceable in any case.

However, I think a likelier explanation is connected to the reason why the flight was late departing from Dublin. The computer system that is linked to the automatic boarding pass reader at the departure gate seemed not to be working. The Flybe staff there had to check every document by hand, and cross names off a printed list as they went through the departure gate. The final tally of passengers also took a while to produce, so we left about 25 minutes late.

I suspect that whatever the problem was with Flybe’s systems, some of the passenger data usually registered for each flight was not available. When authorities at Cardiff were informed about this, an additional precautionary check was performed. I think this is a good theory, as it provides a unified explanation of two unique phenomena (unique in my experience of the Dublin-Cardiff route, that is).

Anyway, although I was surprised at to find uniformed people checking passports when I arrived, and mildly concerned that I might miss the 10.00am bus from the airport to Cardiff, I have travelled enough to realise that it’s never a good idea to make a fuss or even a joke when immigration officers are involved; it never achieves anything and they rarely possess even the most rudimentary sense of humour. And I got on the bus with plenty of time to spare….

Incidentally, when arriving in Dublin from Cardiff there is no specific arrival area for passengers from the UK who must proceed to passport control along with everyone else. A person travelling from the UK to Ireland does not have to show a passport – an ID card will suffice – but the UK does not have a system of ID cards so the only photo-identification most of us have is a passport. In practice, therefore, I show my passport when I arrive. In fact I usually show it to the automatic barrier that reads e-passports, which is far quicker than joining the queue for those with old passports or other forms of ID. At least the automatic machines work in Dublin…

A Day at DIAS

Posted in Biographical, Books, Talks and Reviews with tags , , on March 27, 2018 by telescoper

Last night I flew back to Ireland for a few days of work here before the Easter Weekend. The schedule of flights from Cardiff to Dublin has changed for the spring, with the afternoon flight much later: at 7.45pm instead of 3.40pm, so I left from Cardiff after work on Monday and had dinner in the airport (an overpriced and barely edible beefburger).

Although there is no teaching in either on Maynooth or Cardiff this week I had to come to Ireland for a few reasons, including giving a seminar today at the Dublin Institute for Advanced Studies (DIAS) this afternoon which provided me with the chance to visit it for the first time.

It being a pleasant morning I walked to DIAS from Connolly Station after taking the train there from Maynooth. It’s about half an hour’s walk.

DIAS is actually spread over several sites. Officially my talk was at the School of Theoretical Physics, but there were some people there from the School of Cosmic Physics, which is located not too far away. There were also a few people from Maynooth there, as there are a number of collaborations going on between the two institutions involving staff and students. There was also a visitor from even further afield, in the form of Cormac O’Rafferty who also visits this blog from time to time.

Anyway I had a nice curry for lunch before the talk, which generated a lot of questions from which I infer that it was either confusing or stimulating (or possibly both). Here are the slides in case anyone feels like taking a look.

For a change I decided to take the train back to Maynooth from Pearse rather than Connolly, but as it was rush hour I found it packed.

Maynooth by contrast is very quiet with most students away for the break. I can also report that the annoying roadworks that have been going outside my Maynooth residence for months have now finished.

Anyway, thanks to my hosts at DIAS for inviting me and I hope my talk was reasonably bearable. Hopefully this will be the first visit of many!

Equinoctial Molehills

Posted in Biographical, Bute Park, The Universe and Stuff with tags , , , on March 20, 2018 by telescoper

Very busy today, what with a return to lecturing in Cardiff and so on, so I’ve just got time for a quick post to mark the fact that the Vernal Equinox in the Northern Hemisphere took place today, Tuesday 20th March 2018, at 16.15 UTC (which is 16.15 GMT). This means that the Sun has just crossed the celestial equator on its journey Northward. Some people regard this as the first day of spring, which is fair enough as it does correspond fairly well to the end of the Six Nations rugby.

It wasn’t exactly spring weather when I walked into work this morning, as there are still bits of snow around in Bute Park.

More significantly, a huge number of molehills have appeared. Not quite a mole of molehills, but still quite a few. I’m not sure of the reason for all this molar activity. Perhaps moles have special rituals for marking the Vernal Equinox?

Incidentally I was dismayed to see that my Royal Astronomical Society diary gives the time of the 2018 Vernal Equinox as 16.16 GMT while the wikipedia page I linked to above gives 16.15 GMT. I find a discrepancy of this magnitude extremely unnerving. Or am I making a mountain out of a molehill?

Back to work in Cardiff..

Posted in Biographical, Education with tags , on March 19, 2018 by telescoper

So here I am, then. Back in the offices of the Data Innovation Research Institute in Cardiff for the first time in almost a fortnight. The four-week batch of strikes over pensions has come to an end so I have returned to work. No agreement has been reached so it seems likely there will be further industrial action, but for the time being normal services are being resumed. In fact it’s not exactly back to normal because there’s a large backlog of things to be done (including marking coursework and setting examinations), but I mean at least that lectures resume and will be delivered on the normal timetable. In my Physics of the Early Universe module I have only given four (two-hour) lectures and have missed three. I return to the fray tomorrow morning to give Lecture 8. Frustratingly, that’s the only lecture I have before the Easter break which starts on Friday and lasts for three weeks. Assuming there are no further strikes I’ll be giving lectures 9-12 (the last a revision lecture) after the holiday.

I now have to figure out how to cope with the six hours of lectures missed because of industrial action. That will be tricky, but I’ll do my level best to ensure that I cover everything needed for the examination. I spent most of this morning trying to figure out how to reorganise the remaining material, and I think I can do it as long as we don’t lose any more teaching time. At any rate I have made the decision not to give additional lectures to cover what I’ve missed. Owing to the timing of the strikes (and the fact that only work half the time here in Cardiff) I have been on strike for all the days I would have been working for three weeks. That means I will lose three full weeks pay. Even if it were logistically possible to fit in 6 hours of extra lectures after Easter, I don’t think it’s reasonable for me to do that for free.

While I was on strike a group of my students emailed the Vice-Chancellor of Cardiff University (copying me in) to point out how much teaching they were missing and request some form of compensation. I have a lot of sympathy for their situation and in no way do I want to damage their education. I will do what I can to mitigate the effect of the strike but won’t take any action that reduces the effectiveness of the industrial action. It remains to be seen if any compensation will be offered by the University management, but I think their best policy would be pressure Universities UK to stop pratting about and find a speedy settlement of the dispute.

Anyway, today is a bank holiday in Maynooth – St Patrick’s Day fell on a Saturday this year – and the rest of the week is `Study Week’, so there are no lectures or laboratory sessions. I’ll therefore be staying in Cardiff all week, which gives me the chance to go to a concert on Friday at St David’s Hall – the first for quite a while.

Now, time to get back to writing tomorrow’s lecture…

Anyone for Cricket?

Posted in Biographical, Cricket with tags , on March 18, 2018 by telescoper

Going through the mail that arrived during the ten days or so I’ve been in Ireland, and with the snow steadily descending outside my window, I find the handy booklet containing this year’s fixtures for Glamorgan County Cricket Club has arrived at last.

Glamorgan’s first County Championship match starts on April 20th, just a month away, but their first home game isn’t until May (against Kent) . Hopefully the snow will have melted by then!

I now have a bit of planning to do in order to fit in as much cricket as I can this summer in between trips to and from Ireland as well as conferences and other things…
