Posted in Uncategorized with tags Maynooth, Power Cut, UCU, UCU Strike, USS Pension on April 13, 2018 by telescoperToday has been a very strange day. The strangeness started last night when, without any notice being given to us mere residents, a crew arrived at 8pm to do roadworks (resurfacing). There then followed an excruciating racket right outside my window well into the early hours of the morning.
So, having not had much sleep at all, I wasn’t in a very good mood when I got up. Things went from bad to worse when, just after 8am, all the electricity in my flat went off. I checked the trip switches and saw no problem. I then went outside and saw the traffic lights were off. It turned out that the power supply to all of Maynooth was off (including the entire University), as well as quite a bit of the rest of County Kildare.
With no electricity I couldn’t have a shower or make any coffee or have the bacon sandwich I’d planned to have for breakfast. The prospect of sitting in a cold flat all morning with nothing to do and not even the radio to listen to didn’t appeal so I got dressed and went to the office (which is only 15 minutes walk away). No shops were open on the way. There was no electricity anywhere on campus, so no internet connection, and quite a lot of students sitting around wondering what to do. At least the office was fairly warm and I had plenty of things I could do without a computer.
News eventually started coming through that power was returning gradually to the campus buildings. Ours came back at about 10.30. At that point I finally got a cup of coffee. I still don’t know what caused the fault.
The other major event of the day was that the result came through from the Universities and Colleges Union ballot on whether to accept the Employers’ offer on pensions. A majority of the members voted `yes’, so strike action – which had been planned to resume at Cardiff on Monday 16th April – is now suspended. I wouldn’t bet against a resumption later this year, as the major issues seem to me unresolved. However, I will be leaving Cardiff in July so that’s the end of the matter for me.
Anyway, this now means that I’ll be resuming my teaching in Cardiff on Tuesday next week (17th April). I’d already decided to spend this weekend in Ireland so I’ll be going back on Monday morning, Flybe willing…

Posted in Uncategorized on April 12, 2018 by telescoperInteresting post about the USS pension `deficit’ and why it is strongly dependent on the valuation method.
This post is a little off-topic, as the exercise I am about to illustrate is not one that most corpus linguists will have to engage in.
However, I think it is a good example of why a mathematical approach to statistics (instead of the usual rote-learning of tests) is extremely valuable.
Case study: The declared ‘deficit’ in the USS pension scheme
At the time of writing nearly two hundred thousand university staff in the UK are active members of a pension scheme called USS. This scheme draws in income from these members and pays out to pensioners. Every three years the pension is valued, which is not a simple process. The valuation consists of two aspects, both uncertain:
- to value the liabilities of the pension fund, which means the obligations to current pensioners and future pensioners (current active members), and
- to estimate the future asset value of the pension fund…

Posted in Uncategorized on April 3, 2018 by telescoperIt being my first day back after the Easter break I’ve been too busy to write a proper post but I do have time to pass on a piece of important news about passports. Those of you UK citizens worried having to trade your lovely burgundy passport for a nasty blue one need fret no more.
According to the BBC news, you can carry on using your current passport until you expire:

I hope this clarifies the situation.
P. S. My own expiry date has been helpfully provided by the Irish government on my recently provided PPS card:

Why Physicists Leave Physics
Posted in Uncategorized on March 31, 2018 by telescoperInteresting post. Only about one in twenty PhDs go on to be professors in the long run. People leave academia for various reasons, not all of them negative, but I still think we overproduce PhDs in the UK. There has never been a proper study of the merits of funding fewer PhDs and more Masters degrees, for example.
It’s an open secret that many physicists end up leaving physics. How many depends on how you count things, but for a representative number, this report has 31% of US physics PhDs in the private sector after one year. I’d expect that number to grow with time post-PhD. While some of these people might still be doing physics, in certain sub-fields that isn’t really an option: it’s not like there are companies that do R&D in particle physics, astrophysics, or string theory. Instead, these physicists get hired in data science, or quantitative finance, or machine learning. Others stay in academia, but stop doing physics: either transitioning to another field, or taking teaching-focused jobs that don’t leave time for research.
There’s a standard economic narrative for why this happens. The number of students grad schools accept and graduate is much higher than the number of professor jobs. There simply isn’t room…

Stephen Hawking Remembered
Posted in Uncategorized on March 30, 2018 by telescoperI wasn’t really planning to post anything over this Easter break but I thought I’d make a small exception just to direct you to a radio programme and podcast that I contributed to about Stephen Hawking, who died recently.
You can find the link to a podcast of the episode of Pythagoras’ Trousers originally broadcast on Radio Cardiff that features my ramblings, as well as a longer, unedited version of the interview I contributed, with some more technical content, here.
And let me also take the opportunity to send my best wishes to everyone of any faith or none over the forthcoming holiday!

Posted in Uncategorized on March 3, 2018 by telescoperI wrote this post on Thursday, after a long and busy day, in a hotel near Paddington station, having long since given up the possibility of returning to Cardiff today owing to the inclement weather conditions. Fortunately I had taken my overnight things and a change of clothes in anticipation of the likelihood of getting stranded.
Unfortunately the hotel WiFi crapped out and it seems it never got posted, so I’ve updated it and here it is now. I was in London for the launch event for the LGBT Physical Sciences Climate survey.
Before going on please let me wish you a belated Dydd Gŵyl Dewi Hapus, as Thursday was St David’s Day!
I rose at 5 o’clock on Thursday morning to get the 6.26 train to London to participate in this event. It was all going well until we reached Swindon (about halfway into the journey) but then we warned that Paddington station was closed and the train would be terminating at Reading. I was a bit surprised by this as there wasn’t really very much snow at all, but it turns out that the snowy conditions had made Paddington too slippery to be safe. That’s no doubt because of the shiny floors added at great expense but very little point when the station was refurbished some years ago. At no point on the journey into London did I see more than half an inch of snow. It’s truly pathetic that such total disruption of this major transport route resulted from such a small amount of snow.
I was advised by the GWR staff at Reading to turn forget about making it to London and instead to get on the train back to Cardiff, as no trains were going into out out of London and snow was heading for Cardiff making it unlikely I would get back this evening even if I did continue on my journey.
Eschewing this advice I found that trains were leaving from Reading to Ealing Broadway, so I got one of those and took the Central Line underground from there into town. I arrived about 11am at the Institute of Physics, about two hours later than planned but I had left early in anticipation of likely delays.

Anyway, the event itself seemed to go quite well. I gave a little introductory talk, followed by four other speakers, and then chaired a panel discussion. Here’s a few pictures:


The participants (from left to right) were: Dr Ashley Spindler, Dr James Claverley, myself, Niamh Kavanagh, and Professor Dave Smith. There then followed a little drinks reception and a group of us subsequently adjourned to a local pub for drinks.
Anyway, the main point is that the survey is now live and can be found here. That link also tells you who’s eligible to complete it.
The survey is open until the end of April so I’ll probably post a few reminders over the next few weeks…
Follow @telescoperValue for money in higher education: a very English debate
Posted in Uncategorized on February 25, 2018 by telescoperQuite long, but very informative, blog post about the problem of defining ‘value for money’ in higher education. Well worth reading.
[ex-] HEAD OF DEPARTMENT’S BLOG
The term ‘value for money’ is now deeply entrenched in public discourse about higher education in England. It is written into the Higher Education and Research Act. It is the subject of an ongoing enquiry by te House of Commons Education Committee, and it has launched a few dozen identikit newspaper columns. It is at the centre of what the Office for Students describes as a ‘major piece of research’ that it has
recently commissioned, intending to probe students’ perceptions of value for money to ‘inform’ how the OfS ‘takes forward its legal responsibilities to promote’ it. And no doubt it will in turn inform the thinking of Sam Gyimah, the new minister for Higher Education and Science, as he implements the review of student finance and university funding announced last week.
But one missing element in this debate is an agreed definition of value for money. When we talk…
