The Weather and the LGBT Physical Sciences Climate Survey.

Posted in Uncategorized on March 3, 2018 by telescoper

I 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…

Value for money in higher education: a very English debate

Posted in Uncategorized on February 25, 2018 by telescoper

Quite long, but very informative, blog post about the problem of defining ‘value for money’ in higher education. Well worth reading.

amcrae2014's avatar[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…

Today’s Earthquake in Wales

Posted in Uncategorized on February 17, 2018 by telescoper

Just after 2.30 this afternoon I felt a vibration of my house in Cardiff, initially like a heavy truck going outside but then a distinct ‘bump’. The whole house moved, but only for less than a second and no damage ensued.

I thought it was a minor tremor, and out of curiosity I looked on Twitter to see how widespread were the reports. The answer was very:

It seems it was an earthquake of Magnitude 4.7, centered near (or, presumably, under) Neath. That’s actually pretty big by UK standards.

Thankfully I don’t think anyone has been hurt.

Anyone else feel it?

P. S. I learned today that the Welsh word for ‘earthquake’ is daeargryn..

Flying back to Wales

Posted in Uncategorized on February 17, 2018 by telescoper

Today, as usual, I took the morning flight back from Dublin to Cardiff. This was the first time this year it’s been clear enough and light enough to see anything from the cabin so I took this snap our of the window as we reached the Welsh coast. You can see the curve of Cardigan Bay reasonably well.

The propeller was working, by the way…

Windows Horror

Posted in Uncategorized with tags , on February 16, 2018 by telescoper

This week was going reasonably well, I thought. The class test for my Computational Physics students yesterday went reasonably well; they even managed to upload their code and output to Moodle at the end.

However, when I came into work this morning and started up my laptop, which belongs to Cardiff University, it announced that it was doing a BIOS update. I sighed and then went to make a cup of tea while it did the job. When I got back I found I was locked out by BitLocker, the Windows 10 disk encryption feature that Cardiff University insist is used on its laptops.

There isn’t/wasn’t any USB disk attached to the machine, by the way, and I did try restarting the machine but that didn’t help. I can only infer that BitLocker can’t cope with a change at the BIOS level which, if true, is really pathetic.

Not having the required `recovery key’ (which I have never been given) and being informed by the FAQ that I would need a system administrator to supply it, I got in panicky touch with Cardiff’s IT services, but three hours later I still can’t get in. I do have my desktop (which runs Unix) so am not completely stymied, but I don’t have the files on my laptop. I was planning to work on some things on there today, but it looks like I won’t be able to. It even looks possible that all the data on this laptop is lost for good.

The thing I can’t help thinking about is how terrible this would be if I had been just about to give a talk at a conference….

WINDOWS UPDATE: I’m back into my laptop and have not lost any data (as far as I can tell). The problem is indeed a known conflict between BIOS and BitLocker, which I think is atrocious.

Dictionary Distribution Day

Posted in Biographical, Cardiff, Crosswords, Uncategorized on January 30, 2018 by telescoper

This set of dictionaries arrived last week while I was in Maynooth.

These – along with £15 in book tokens which arrived a while ago – form the prize for the Everyman Crossword competition in the Observer I won earlier this month.

Fortunately, my friendly neighbours accepted delivery of the books while I was out and I collected the parcel from them last night after work. I took them into work today and distributed them gratis to deserving members of the School of Physics & Astronomy before my first Physics of the Early Universe lecture this morning. I’ve got plenty of dictionaries already, you see.

I wonder if I’ll win any more before I move to Ireland?

Frank Kelly’s Christmas Countdown

It’s time for the famous Cardiff Physics & Astronomy Christmas Lunch, so I’ll get into the Christmas spirit and just leave this here:

Messiah

Posted in Biographical, Cardiff, Music, Uncategorized with tags , , , on December 10, 2017 by telescoper

A performance of Handel‘s Messiah  at St David’s Hall  is always a pretty sure sign that the Christmas season is upon us, although the work itself was actually first performed at Easter and it’s by no means clear why it ended up almost universally regarded as a Christmas work . Messiah actually spans the entire biblical story of the Messiah, from Old Testament prophecy to the Nativity (Part 1) , the Passion of Christ (Part II, culminating in the Hallelujah Chorus, and the Resurrection of the Dead (Part III). The Nativity only features (briefly) in Part I, which is why it’s a little curious that Messiah is so strongly associated with Christmas.

Whatever the reason I don’t mind admitting that Messiah is a piece that’s redolent with nostalgia for me – some of the texts remind me a lot of Sunday School and singing in a church choir when I was little and then, a bit later, listening to the whole thing at Christmas time at the City Hall in Newcastle. I loved it then, and still do now, over 40 years later. I know it’s possible to take nostalgia too far – nobody can afford to spend too much time living in the past – but I think it’s good to stay in contact with your memories and the things that shaped you when you were young. I went to a performance of Messiah (in the same venue) about this time last year but I relished the chance to hear it again last night.

As it turned out, the pairing of Cardiff Polyphonic Choir with baroque orchestra Réjouissance produced a very different performance from last year. The choir, numbering about sixty members, was in fine voice and the much smaller orchestra meant that the chorus really dominated the show.

Generally speaking I’m not a fan of period instrument performances. I can see the virtue of having a lighter instrumental touch in this case, and don’t have a problem with using forces of similar scale to those Handel would have used (e.g. two oboes, two cellos, one double bass, etc). I do not however understand why musicians insist on using outdated instruments. This is particularly true for the trumpets. Nobody will ever convince me that a baroque trumpet isn’t an inferior version of the modern instrument. All credit to the players for doing the best they could, but I really don’t see the point.

Anyway, that rant aside, I very much enjoyed the performance, especially the lovely singing by all four soloists and the choir, who were outstanding.
Now, I wonder where I’ll hear Messiah  next year?

Simplified Presentation 

Posted in History, The Universe and Stuff, Uncategorized on November 24, 2017 by telescoper

This morning I was looking through my collection of old books about general relativity and related things, and found this page as part of a `simplified presentation’:

I wonder if you can guess the name of author of the little book in which I found this page, and what it is a `simplified presentation’ of?

The answer is on the front cover:
