Back to Barcelona

Posted in Barcelona, Biographical with tags , on May 3, 2024 by telescoper

So, after a brief sojourn in not-Barcelona, I am back in  Barcelona for what is not a Bank Holiday weekend. Wednesday 1st May was celebrated here with a public holiday as International Workers Day but, in the UK and Ireland, the May Day holiday is on Monday 6th (and in any case is not so much a workers’ holiday but a spring festival of much older origin.

Right now, just after 7.30pm, it is a pleasant 19°C here, a bit warmer than in Ireland. It seems, however, that there was torrential rain for much of the day on Monday. It rained so much in fact that there is even talk of the current drought restrictions being eased. Yesterday, my flight here was delayed by a mysterious weather event that temporarily closed the airport, although what had happened was never fully explained.

From now on, temperatures are forecast to rise steadily until the real heat of the summer arrives. I have this apartment until the end of June and, at some point soon, I have to decide how much longer to stay in Barcelona. My sabbatical lasts until the end of August, but the University is closed for that month, and I would probably find the heat intolerable then anyway. The question is whether to stay for July…

This month will be very busy, with some important results from Euclid coming out on 23rd May and a number of things related to that. Before all that, though, I’m going to have a drink or two on the terrace. There may not be a Bank Holiday coming, so it’s not a Long Weekend but it’s still a weekend!

.Astronomy

Posted in Barcelona, Euclid, The Universe and Stuff with tags , , , , , , , , on April 24, 2024 by telescoper

So here I am at the European Space Astronomy Centre (ESAC) just outside Madrid for a conference called .Astronomy 13. It is (obviously) the thirteenth such conference but the first that I have attended. I’m giving a plenary talk in half-an-hour or so. I travelled from Barcelona by train yesterday evening, which was a comfortable and uneventful trip, the (approximately) 504 km from Barcelona to Madrid Atocha station taking about 2 hours and 30 minutes that cost about 30 euros. I stayed overnight in Madrid and took a shuttle bus from to ESAC. The only glitch in my travels so far was that I got on the Metro Line 6 (the equivalent of the Circle Line), but chose the wrong platform and went the long way round. I still got there in time to get the shuttle.

Incidentally, ESAC hosts the Euclid Science Operations Centre (SOC) which plays a central role in the processing of data from Euclid and is also responsible for the development and operations of the Euclid Archive from which data will be distributed to the global astronomical community.

UPDATE: Back in Barcelona. The return by train was just as smooth an uneventful as the outbound journey, and in fact arrived back about five minutes ahead of schedule. Thanks to the organizers for inviting me – I’m sorry I couldn’t stay for longer as I like the idea of the .Astronomy meetings. Perhaps we should have one in Ireland sometime?

Diada de Sant Jordi

Posted in Barcelona, History with tags , , , , , , on April 23, 2024 by telescoper

Today, 23rd April, is Diada de Sant Jordi (Saint George’s Day) which, though not a public holiday, is a very special occasion in Barcelona. Saint George is of course familiar to me as the Patron Saint of England, and of quite a few other places, but wasn’t aware until a few weeks ago that he is also the Patron Saint of Catalonia.

Not much is known about Saint George, but it is believed that he was born in Cappadocia (modern-day Turkey, then part of the Roman Empire) to parents of Greek origin, and that he fought in the Roman army and died in 303 AD in Syria Palaestina (also part of the Roman Empire). There is no evidence that he ever visited England or Catalonia for that matter. It seems that he began to be venerated around about the time of the First Crusade, which happened over seven hundred years after his death.

Anyway, the Festa de Sant Jordi is celebrated in a very civilized and charming way in Barcelona. Traditionally the celebration involved giving gifts of flowers (especially roses) to women and gifts of books to men. That is obviously a bit sexist so nowadays you can give flowers and books to whomever you wish. In order to facilitate this, quite a large area of the Eixample district around my apartment is largely closed off to traffic today, refuse collections have been paused, and there are stalls selling books or flowers filling up the pavements. It was especially busy this morning on Passeig de Gràcia, where the combination of queues at the bookstalls and queues for the Casa Batlló generated a big crowd, but the atmosphere was very friendly and nice (apart from a few car drivers upset at the road closures).

Here are a couple of video clips which will hopefully give you an idea of what it was like:

And here are some random pics

I wish I could visit the celebrations again, but this afternoon I have to take the train to Madrid for a conference.

Problematic Pollen

Posted in Barcelona, Biographical with tags , , , , on April 22, 2024 by telescoper

Four years ago, in the early months of the pandemic, back in April 2020 I wrote a post that mentioned an allergy I thought was due to tree pollen which I had noticed taking walks for exercise around the deserted Maynooth University campus. I hadn’t experienced such a thing before but didn’t know whether I had developed it in later life or whether I’d just never previously been exposed to the source. I did subsequently discover, by experimentation, that the culprit was oak pollen.

Well, for the last couple of weeks I have been suffering from a similar, but rather more severe, form of allergic reaction which I assumed was caused by tree pollen. This one doesn’t just provoke sneezing but also makes my eyes go red and watery. There are many trees of different types in the streets of Barcelona. For example, the road on which I live, Rambla de Catalunya, is lined with Lime trees (Linden); these don’t cause a reaction. Another common species is the Plane (Sycamore) and that’s OK for me too.

To identify the culprit I did some experiments similar to what I did four years ago. This wasn’t too difficult because particular streets seem to have been planted with particular trees. And so it came to pass that I soon identified the culprit, Quercus Ilex, of which there are few in places near me, including Passeig de Gràcia and Plaça de Catalunya, as seen here:

Quercus Ilex

Quercus Ilex is the botanical name for the Holm Oak (or Holly Oak), an evergreen member of Oak family in contrast to the English Oak (Quercus Robur) which is deciduous. So it seems that pollen of the genus Quercus produces a quirk of my immune system…

The Inaugural Euclid Spain Meeting

Posted in Barcelona, Euclid, The Universe and Stuff with tags , , , , on April 18, 2024 by telescoper

So here I am at the Institut de Ciencies de L’Espai (ICE-CSIC) which is on the campus of the Universidad Autónoma de Barcelona (UAB) for the first ever Euclid Spain Meeting. This involved a 40-minute trip on the S2 train from Plaça de Catalunya, which is a short walk from my apartment, then a short walk from the railway station at UAB through the campus to the Institute.

I was able to speak at this meeting because I happen to be in Barcelona right now. I mean that I was able to attend because I was in Barcelona anyway, not that the meeting was held because I am in Barcelona!

Anyway, I gave my talk early on this morning, so have been able to enjoy the rest of the day having got that out of the way. There are about 50 people here. It’s great to see the sizable Euclid community in Spain getting together and sharing their work.

P.S. My surname always causes some amusement in Spain, as “Coles” means “Cabbages” in Spanish…

Mini-Heatwave

Posted in Barcelona, Biographical on April 15, 2024 by telescoper

If it was warm on Saturday it was even warmer on Sunday. I went for an afternoon walk down to the harbour but was unfortunately unable to remember which of the yachts is mine so instead of putting out to sea, I had an ice cream and returned home for a siesta.

Obviously 27°C isn’t really hot by the standards of Barcelona but it is only mid-April and the temperature at the weekend in some areas did get up to 29.1°C, which is the highest temperature in April since 1914. It was about 10°C higher at the weekend than last week. The forecast for this week is similar to last week, around 18°C

Torre de Comunicacions de Montjuïc

Posted in Barcelona on April 14, 2024 by telescoper

It was rather warm yesterday, even near sunset, so I found myself sitting out on my balcony, staring out into the distance, with a small bottle of wine by my side, and decided to record the view. Off in the distance, with the flashing lights, is the Montjuïc Communications Tower, which was built to transmit television signals from the 1992 Barcelona Olympics. To the left you can see the dome and spires of the Palau Nacional. The traffic noise is authentic.

El Castell de Barbablava – Teatre del Liceu

Posted in Barcelona, Opera with tags , , , , , on April 13, 2024 by telescoper

I was thinking last weekend that in, all the time I’ve spent in Barcelona this year, and all the times I’ve travelled through the Metro station called Liceu, I’ve never been inside the Gran Teatre del Liceu. I decided to remedy that by booking a ticket to see last night’s performance of Bluebeard’s Castle, a one-act Opera by Béla Bartók. The theatre is actually on La Rambla, and I had to dodge through the hordes of tourists to get there, but it’s an easy walk from my apartment.

El Liceu is indeed very beautiful inside and deserves its reputation as one of the world’s finest opera houses. The main hall is about the same size as that of the Royal Opera House in Covent Garden, with a seating capacity of over 2,000, and it does have a similar decor, with red and gold everywhere. When I booked my ticket (on Monday) there were plenty of seats available to choose from, so I wondered what the attendance would be like. As it turned out, it wasn’t quite full but there was a good crowd in.

I have seen Bluebeard’s Castle a couple of times before, but it surprises me that there are no old reviews in my back catalogue on this blog. From that observation I deduce that both times I saw it were before 2008, which is when I started blogging. I do think it’s a masterpiece, however, which is why I jumped at the chance to see and hear it again. Last night’s was a concert performance, i.e. without staging, which works well with this Opera as there are only two principals and it sometimes it’s good to leave a lot to the listener’s imagination. The performance was in the original Hungarian language, with surtitles provided in Catalan, Spanish and English.

The Opera is based on a French folk legend of Bluebeard, a murderous character foreshadowing Jack the Ripper, and Judith, who has for some reason fallen in love with him, despite it being widely believed that he murdered his previous wives. She travels with him to his castle and, when they arrive, she starts to ask Bluebeard some uncomfortable questions as she makes her way through the dark castle. Seven doors appear to which Bluebeard holds the keys. Each one will reveal information about the personality and past of a Bluebeard. The first door opens to reveal a blood-soaked torture chamber, for example. And that’s just the start…

The final door reveals his former wives, apparently still alive. But are they ghosts? Who knows? Judith doesn’t seem to mind. She becomes the fourth wife and disappears into the darkness enfolding the other three. That’s the end.

The Opera doesn’t really have that much to do with the folk story. It is really an allegory – the rooms contain secrets of Bluebeard’s past, including past relationships, which he has locked away deep inside himself. Only Judith’s persistent questioning can persuade him to reveal them.

The music for Bluebeard’s Castle is extraordinarily rich and varied, changing as each door is opened. A large orchestra is needed to produce these changes of texture, as you can see in the picture I took before the performance. The musicians, under the direction of Josep Pons, played superbly as well as supplying eery sighs when the libretto demanded it. Vocals were supplied by bass-baritone Nicholas Brownlee as Bluebeard and mezzo soprano Victoria Karkacheva; both were excellent.

The performance lasted only about an hour. One of the things about going to an Opera in the evening is that one usually has to have something to eat before the performance, because it’s likely to be too late afterwards to find anywhere still serving food. That doesn’t apply here in Spain, where people generally eat rather late. I was thinking as I left last night that it was the first time I had been to an Opera that started at 7.30pm after which it was still too early to have dinner!

In Praise of the Public Thesis Defence

Posted in Barcelona, Education, The Universe and Stuff with tags , , , , , on April 12, 2024 by telescoper

The ICCUB is quite large, which means that there are quite a few talks to go to, including seminars and colloquia but also thesis defences, such as one I attended this morning. The format for these events is a talk by the candidate in the presence of a panel of experts, who ask questions at the end, but the whole thing is open to the general public. After the panel questions there is an opportunity for questions from the audience, but only from those who have a doctorate. I was tempted, but didn’t put my hand up.

Anyway, this morning’s talk was well attended and of very high quality and, as usual, the whole event lasted getting on for two hours. It’s a very different experience from the form of viva voce examinations used for PhDs in the UK and Ireland.

I like to attend these public thesis defences because they’re a very good way of finding out about the research going on in areas away from my own specialism. In physics the people who are really working at the coal face are the PhD students so one often learns more about the details from such talks than from colloquia from senior folk, which are usually cover a wider area but at a more superficial level.

Another nice thing is that there is a little gathering afterwards (on the right) with a selection of food and drink available to celebrate the candidate’s success. In fact it was a double celebration as the candidate was offered a postdoctoral research position just two days ago. I abstained from the champagne as alcohol at lunchtime usually sends me to sleep in the afternoon, and I have a lot to do in the rest of today.

R.I.P. Peter Higgs (1929-2024)

Posted in Barcelona, Maynooth, R.I.P., The Universe and Stuff with tags , , , , , on April 9, 2024 by telescoper

I was very sad this afternoon to hear of the death of theoretical physicist Peter Higgs, on Monday 8th April 2024, at the age of 94. I never met Peter Higgs but I know how greatly liked and respected he was (see, e.g. here) and that he leaves an important legacy as a physicist, particularly the work that led to the award of the 2013 Nobel Prize for Physics (jointly with François Englert) . Condolences to his family, friends and colleagues.

You can read the very nice Guardian obituary here; there are many others published in media from elsewhere in the world (including Ireland and Barcelona).

I’ll add two extremely slight connections. One is that Peter Higgs visited Maynooth University in 2012, not long before his Nobel Prize was announced. The other is that he was born in the Elswick area of Newcastle upon Tyne, not far from Benwell, where I grew up.
