June, by Francis Ledwidge

Broom out the floor now, lay the fender by,
And plant this bee-sucked bough of woodbine there,
And let the window down. The butterfly
Floats in upon the sunbeam, and the fair
Tanned face of June, the nomad gipsy, laughs
Above her widespread wares, the while she tells
The farmers’ fortunes in the fields, and quaffs
The water from the spider-peopled wells.
The hedges are all drowned in green grass seas,
And bobbing poppies flare like Elmo’s light,
While siren-like the pollen-staind bees
Drone in the clover depths. And up the height
The cuckoo’s voice is hoarse and broke with joy.
And on the lowland crops the crows make raid,
Nor fear the clappers of the farmer’s boy,
Who sleeps, like drunken Noah, in the shad
And loop this red rose in that hazel ring
That snares your little ear, for June is short
And we must joy in it and dance and sing,
And from her bounty draw her rosy worth.
Ay! soon the swallows will be flying south,
The wind wheel north to gather in the snow,
Even the roses spilt on youth’s red mouth
Will soon blow down the road all roses go.

by Francis Ledwidge (1887-1917*)

*One of Ireland’s foremost poets of the First World War, Ledwidge was killed in action on 31st July 1917 at the Battle of Passchendaele.

Cardiff Philharmonic Orchestra: Mahler Symphony No. 3

Posted in Biographical, Cardiff, Music with tags , , , , on June 18, 2018 by telescoper

Well, I’m back in Maynooth after a weekend in Cardiff, on the Sunday of which I went to St David’s Hall to see the Cardiff Philharmonic Orchestra playing Gustav Mahler’s Third Symphony. Actually this concert was originally scheduled to take place on the evening of Friday 15th June, which is why I booked a ticket to return from Bonn in time to see it instead of waiting for the formal close of the meeting. As it turns out, my flight was so late I would have missed it but fortunately the Rolling Stones intervened. Because Jagger et al were performing at the Principality Stadium in Cardiff on Friday (with all the consequent congestion and traffic disruption that implies) it was decided to shift the concert to Sunday 18th, but I couldn’t be bothered to change my flight.

Anyway, it proved an excellent way to spend a Sunday afternoon. Gustav Mahler spoke of his Third Symphony as being “of such magnitude that it mirrors the whole world” and you can see what he was getting at by just looking at the scale of the forces arrayed on stage when it’s about to be performed live. For yesterday’s concert at St David’s Hall, the Cardiff Philharmonic Orchestra was augmented by the WNO Community Chorus and the Choristers of St David’s Metropolitan Cathedral Choir, as well as soloist mezzo soprano Kate Woolveridge.

The orchestra needed to perform this extravagant work is much larger than for a normal symphony, and it involves some unusual instrumentation: e.g. two harps, a contrabassoon, heaps of percussion (including tuned bells and double tympanists), etc. The string section was boosted by double-basses galore, and there’s also a part (for what I think was a flugelhorn) to be played offstage. The work is also extremely long, being spread over six movements of which the first is the longest (over 30 minutes). Yesterday the performance stretched to about 1 hour and 40 minutes overall, with no interval. I don’t know of any symphonic works longer than this, actually.

It’s worth pointing out that the orchestra and choir(s) tackling this immense work were non-professional. It’s also worth pointing out that the principal French Horn – who is given a lot to do in this piece – was none other than Dr Bernard Richardson, recently retired from the School of Physics & Astronomy at Cardiff University.

I have to admit I have always had lot of trouble getting to grips with the first movement, in which various themes are repeatedly played off against each other, punctuated by a series of extravagant crescendo passages in which the orchestra threatened to blow the roof off. It is, at times, thrilling but also manic and, to me, rather indecipherable. The second movement, in the form of a minuet, is elegant enough, and was beautifully played (especially by the strings), but in comparison with the wayward exuberance of the first movement it sounds rather conventional.

The third movement, however, is totally gorgeous, especially in the passages featuring the offstage flugelhorn (?) and the string section of the orchestra on stage. From this point this piece started to bring me under its spell. The solo vocalist and choir(s) were marvellous in the fourth and fifth movements, the former a setting of a poem by Nietzsche and the latter a mixture of traditional verse and Mahler’s own words, but it was in the majestic sixth and final movement that the orchestra really reached its peak. This is one of the most romantic movements to be found in all of Mahler, passionate, lyrical and supremely uplifting. At times before the sixth movement the orchestra (especially the brass) had struggled a bit with the demands of the score, but the finale was as good a performance as you’ll hear anywhere.

Mahler’s 3rd Symphony is an epic journey through a landscape filled with dramatic contrasts. At times you wonder where you are going, and sometimes feel in danger of getting completely lost, but by the time you arrive triumphantly at the final destination all those doubts had melted away. Congratulations to the Cardiff Philharmonic on a very fine performance, warmly received by the audience.

After the concert there was a collection on behalf of the Forget-Me-Not Chorus, which supports people with dementia and their families through weekly singing sessions. I think this is a great initiative and made a donation on the way out – if you feel like doing likewise you can do so here.

Well, that’s my concert-going at St David’s Hall over for another season. Indeed, it’s probably the last concert I’ll be attending there for the foreseeable future, as I’ll be relocating fully to Ireland this summer. I’ll have many fine memories of listening to music there.

Trump the Child-catcher

Posted in Uncategorized on June 16, 2018 by telescoper

The above cartoon, protesting against ‘President’ Trump’s policy of forcibly separating young children from their parents and detaining them in cages, got the artist Rob Rogers fired from his job at the Pittsbugh Post-Gazette.

It seems fairly mild to me, given the enormity of what is going on, so I thought I’d share it here.

Advice to anyone thinking of travelling with Eurowings

Auf Wiedersehen, Bonn

Posted in Uncategorized on June 15, 2018 by telescoper

So here I am in Cologne-Bonn Airport waiting for my flight back to London Heathrow. The meeting carries on today with a ‘Garage Day’ but I’m skipping that because I don’t have a car.

Inevitably with Eurowings, my plane is delayed by over an hour, which means I’ll be very late back to Cardiff as I’ll miss the bus I had planned to get.

Update: The plane is now delayed by 2 hours and 10 minutes (and counting..)

The Rolling Stones are on in Cardiff tonight and the flight delay probably means I’ll be arriving exactly at the wrong time, when most of the city centre will be sealed off.

I’ve definitely learnt my lesson with Eurowings on this trip and will not be travelling with them again.

Anyway, the delay gives me an opportunity to thank all the organisers of the 2018 Euclid Consortium meeting, which was very well run indeed!

Euclid 2018: Day 3

Posted in Biographical, Euclid, The Universe and Stuff with tags , , on June 14, 2018 by telescoper

It’s the morning after the conference dinner the night before, so as Day 4 of the Euclid Consortium meeting gets under way I’ve just got the time and bandwidth to do a brief post about the events of yesterday. First of all, the conference photo arrived and is shown above. You’d be hard pressed to spot me in it, as there are a lot of people in it (and bear in mind that only about a quarter of the membership of the Euclid Consortium are actually present here in Bonn).

Yesterday I went to splinter meetings related to the working groups on cross-correlating Euclid with cosmic microwave background data (morning) and clusters of galaxies (afternoon). The latter session produced the following diagram, which makes everything clear:

After the day’s work was done I took a walk down to the western bank of the Rhine (just about 15 minutes’ walk from my hotel), on the way to the conference dinner at the . Sadly, I didn’t see any Rhine Maidens or find any gold to make into a ring.

Anyway, the dinner was at the splendid Rhein Hotel Dreesen and I had the good fortune to sit with some Italian friends from way back – by which I mean over 20 years!

Fortunately I didn’t have far to go to get back to my hotel after the festivities!

Euclid2018: Highlights of Day 2

Posted in Biographical, Euclid, The Universe and Stuff with tags , , , on June 13, 2018 by telescoper

I’ve just had my breakfast so I thought I’d do a quick post before the start of play at Day 3 of the 2018 Euclid Consortium Meeting in Bonn.

Day 2 was largely devoted to updates from the various Science Working Groups, but there was also an important presentation from Jason Rhodes about WFIRST, which is in some ways a rival to Euclid, or perhaps a complementary mission depending on how you look at it.


There was dismay in the global astronomy community last year when Donald Trump proposed taking the axe to WFIRST but it was good to hear that Congress not only reversed his decision but granted it additional funds over and above the original request.

Among the SWG updates was one by Alessandra Silvestri from the Theory Working Group concentrating on how Euclid could be used to test cosmology beyond the standard model. She focussed quite a lot on Horndeski Gravity, which is the most general four-dimensional scalar-tensor theory that leads to equations of motion that have the form of second-order differential equations.

Towards the end of the day there was a session devoted to the award of the Euclid Star Prizes.

The individual awards went to Micaela Bagley, Carmelita Carbone, Teake Nutma, Bertrand Morin, and Stefanie Wachter; more details on the winners and the awards they won will be posted here. The team award was given to the Flagship simulation team. Coincidentally, I posted about the Flagship simulations last year. Much of the preparation for Euclid would be impossible without these simulations, and the award of a prize to the team is very well justified.

The day finished with short talks from each of the prizewinners. That brought to the end two days of plenary sessions in the big hall of the Stadthalle. The next two days will be the `Splinter sessions’ which are held in parallel.

Oh, and one other thing: the 2019 Euclid Consortium Meeting will be held in Helsinki from June 4-7. Looks like I’ll be spending my birthday in Finland next year!

P.S. Previous Euclid Consortium meetings were: Bologna (2011);  Copenhagen (2012); Leiden (2013); Marseille (2014);  Lausanne (2015); Lisbon (2016); and London (2017).

R.I.P. Bepi Tormen (1962-2018)

Posted in Uncategorized with tags on June 12, 2018 by telescoper

Once again I find myself having to use this blog to pass on some desperately sad news. Giuseppe Tormen, universally known as Bepi, passed away on Sunday 10th June at the age of 56.

I knew Bepi mainly from the many visits I made to Padova in the 1990s and early 2000s. As well as many other useful and enjoyable interactions I had with him, Bepi also helped enormously in proving detailed comments and numerous corrections for the book I co-wrote with Francesco Lucchin. His contributions to cosmology were many and varied, but were always characterised by the same very high standard of integrity, insight, diligence and careful accuracy. He was widely admired as an excellent scientist and splendid colleague.

Bepi had been bravely fighting cancer for some time, having defied a very poor prognosis for several years with the aid of experimental treatment, but most recently he developed a brain tumour which sadly proved terminal. My deepest condolences go to his family, friends and colleagues.

Rest in peace, Bepi Tormen (1962-2018).

Bad Godesberg Goody Bag

Posted in Biographical, The Universe and Stuff with tags , , , , on June 12, 2018 by telescoper

So here I am, then, at the start of Day 2 of Euclid 2018 in Bad Godesberg. The morning session contains a number of talks giving updates from the various Science Working Groups related to Euclid. After yesterday’s talks had finished I checked into my hotel which is nice, and then headed off via the Stadtbahn (local underground system) to a pleasant reception of drinks and nibbles in the University of Bonn. I’m very impressed with the local public transport, by the way. With my hotel booking I received a pass giving free unlimited on all buses, trams, overground and underground trains in the area. I’ll post more about the meeting later if I get time, but in the meantime I thought I’d show the contents of the conference Goody Bag: I’ve got quite a collection of conference bags that I’ve accumulated over the years, but this is the first one I’ve got that’s a lurid green colour. There’s a mug and a bag of Haribo sweets (which, I’m told, originate in Bonn). There is also a book which I looked at last night. I found it rather lacking in both plot and character development, but that is largely attributable to the fact that all the pages are blank. The final item, which I originally thought was some form of specimen jar, turns out to be a glass for Kölsch, a kind of beer brewed in Cologne.

 

News from Euclid 2018

Posted in Biographical, Euclid, The Universe and Stuff on June 11, 2018 by telescoper

At the second attempt I managed to check in for my flight to Cologne (which is apparently near a place called) en route to Bonn for the Euclid 2018 Consortium Meeting.

I was mightily relieved when a plane actually arrived this time.

We got to our destination just about on time. I bumped into fellow Euclidean Tom Kitching in the airport and we made it to the conference venue in time for a spot of lunch, after which the afternoon session was kicked off by Mark Cropper:

I missed the morning session, during which the most important piece of news was an official announcement that the launch date of Euclid has been moved back from 2020 until 2022. This was not unexpected, and is largely driven by problems with on-board electronic system, but it will obviously impact the timetable of the mission significantly.

Since the flight of Euclid will be delayed for two years, I wonder which hotel it will be staying in at ESA’s expense?
