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:

Where The North Begins

Posted in Uncategorized with tags , , on November 17, 2017 by telescoper

I see that, once again, questions are being raised in the English media about where The North begins. I see it as symptomatic of the decline of educational standards that this issue is still being discussed, when it was settled definitively several years ago.  Let me once again put an end to the argument about what is The North and what isn’t.

For reference please consult the following map:

 

I think this map in itself proves beyond all reasonable doubt that`The North’  actually means Northumberland: the clue is in the name, really. It is also abundantly clear that Manchester, Leeds, Liverpool, etc, are all much further South than The North. North Yorkshire isn’t in the North either, as any objective reading proves.  All these places are actually in The Midlands.

If you’re looking for a straightforward definition of where The North begins, I would suggest the most sensible choice is the River Tyne, which formed the old Southern boundary of Northumberland. The nameless County shown on the map between Northumberland and Durham is `Tyne  & Wear’, a relatively recent invention which confuses the issue slightly, as including all of it in The North would be absurd.  Surely everyone knows that Sunderland is in the Midlands?

If this cartographical evidence fails to convince you, then I refer to a different line of argument. Should you take a journey by car up the A1 or M1 or, indeed, the A1(M) you will find signs like this at regular intervals:

This particular one demonstrates beyond any doubt that Leeds is not in The North. If you keep driving in a northerly direction you will continue to see signs of this type until you cross the River Tyne at Gateshead, at which point `The North’ disappears and is replaced by `Scotland’. It therefore stands to reason that The North begins at the River Tyne, and that the most northerly point of the Midlands is at Gateshead.

I rest my case.
