Cosmological Simulations down Memory Lane

Posted in Biographical, LGBTQ+, The Universe and Stuff with tags on January 8, 2019 by telescoper

On Friday I have to be in London to give a keynote talk at this year’s LGBT+ STEMinar, which is taking place at the new Institute of Physics Building near King’s Cross. I’ve been struggling to think what to say but a conversation this afternoon with some of our PhD students gave me an idea. I won’t spoil it for those going to the event by giving too much detail away, but it involves going over the past 30 years of cosmology and LGBT+ rights alongside each other, pointing out that in both areas there has been great progress but there is also still very much to do.

Anyway, in the course of this I had a look at my thesis (vintage 1988) and came up with the following pictures, in glorious monochrome:

You can click on them to make them bigger. When I started my graduate studies in 1985 my thesis was supposed to be about the statistical analysis of the cosmic microwave background. The problem was that way back then there weren’t any measurements, so I had to make simulations to test various analysis methods on. The above images are examples that ended up in a published paper.

You have no idea what a pain it was to make these images. I had very limited access to a graphics terminal so I had to send these to a special printer in the computer room  (which was behind closed doors and an airlock) and then wait (sometimes for days) for the operators to process the files and produce a the printout. If they came out wrong the process had to be repeated. It was all frustratingly slow as my programs were quite buggy, at least to begin with.

For those of you interested, these simulations were made using a (two-dimensional) Fast-Fourier Transform method, using a pseudo-random number generator to set up appropriate amplitudes and phases for the Fourier modes. The only even remotely clever bit was to find a way of generating Gaussian and non-Gaussian maps with the same two-point correlations.

In all it took me several months of work to complete the work that went into that paper (which was essentially a thesis chapter). When I look back on it I think if I’d been cleverer – and had a decent graphics screen like you find on a modern PC – I could have done it all in a couple of days!

And now, of course, we have real data as well as simulations!

My point is that things that seem very difficult at the time often look extremely easy in retrospect. And that’s not just the case in cosmology.

 

 

The Book Cover Challenge

Posted in Biographical, Literature with tags , , , , , , , , , , , on January 7, 2019 by telescoper

Over the past week I’ve been participating in the Book Cover Challenge on Twitter, in which you are invited to post every day for a week an image of the cover of a book you love without any further comment or explanation. I’ve now finished the challenge and I thought I’d put the seven books I selected up here.

Since the challenge is over I am absolved of the requirement not to add comments, so I’ll make a few brief observations here. One is that I found it very hard to select just seven books. I love far too many books to do this in any systematic way. The seven picked are just meant to be vaguely representative of the sort of books I read, but they are not really the seven I definitely consider the best. On a different day I could easily have picked a completely different seven.

Anyway, here are some comment on my selections.

 

Book 1 is A Boy’s Own Story by Edmund White. I read this as a teenager, and it had a profound effect on me. It’s the story of an adolescent boy coming to terms with his sexuality in the American mid-West during the 1950s. It is as frank about the description of gay sex as it is truthful about the confusion that goes with being a teenager. When I bought it I didn’t realize it was going to be so sexually explicit or so unflinching in its description of the selfishness of the central character.

Book 2 is a collection of poems by R.S. Thomas. I had to include at least one book of poetry and found it hard to select which. I feel a bit ashamed to have omitted T.S. Eliot’s Four Quartets and Sylvia Plath’s Ariel, but there you go. I only discovered R.S. Thomas when I moved to Wales in 2007, and still cannot understand why his poetry is not appreciated more widely, and I included this collection to encourage more people to explore his verse.

Book 3 is A Suitable Boy by Vikram Seth. I bought this soon after it came out in 1993 and although it is almost 1500 pages long I devoured it very quickly. The novel follows the story of four families over a period of 18 months, and centres on Mrs. Rupa Mehra’s efforts to arrange the marriage of her younger daughter, Lata, to the `suitable boy’ of the title.  Lata is a 19-year-old university student who refuses to be influenced by her domineering mother or opinionated brother, Arun. It’s beautifully written, weaving together the protagonists stories against a vividly painted backdrop of post-Partition India.

Books 4 & 5 are both from the Golden Age of detective fiction, but from either side of the Atlantic.  I’ve cheated a bit with Book 4, as it is actually 4 novels in one book but I had to have something by the greatest American writer of the period, Dashiell Hammett. By contrast I have also included a fine example of the English detective novel, The Nine Tailors by Dorothy L. Sayers. Both Hammett and Sayers managed to transcend the genre of crime fiction and produce genuine works of literature. The Nine Tailors, has an extraordinary sense of detail and atmosphere and a wonderfully imaginative ending. Among the many ingenious features of this novel is the very prominent central theme of bell-ringing (campanology).

 

Book 6 is The Age of Wonder by Richard Holmes. This book describes the scientific discoveries of the polymaths of the late eighteenth century, and describes how this period formed the basis for modern scientific discoveries. It focuses particularly on the lives and works of such characters as Sir Joseph Banks, the astronomers William and Caroline Herschel, and chemist Humphry Davy and also explores the interaction between science and the art and literature of the period, especially poetry. It covers a lot of ground but it’s very wittily done and never gets bogged down.

Book 7, my last choice, is In Cold Blood by Truman Capote. You would probably describe this as True Crime, a genre that is generally typified by crudely sensationalistic works of very little literary (or other) merit. This one is in a very different league, and some regard it as the first ever non-Fiction novel. Based on the real-life murders of four members of a family in rural Kansas in 1959 by Richard Hickock and Perry Smith (for which they were later executed), In Cold Blood has been lauded for its eloquent prose, extensive detail, and simultaneous triple narrative, which describes the lives of the murderers, the victims, and other members of the rural community in alternating sequences. The psychologies and backgrounds of Hickock and Smith are given special attention, as well as the complex relationship that existed between them during and after the murders. Not a comfortable read by any means, but a masterpiece by any standards.

The Old Year’s Blog Statistics

Posted in Biographical on January 1, 2019 by telescoper

Here we are then, in 2019. I’ve been vegetating most of the day but now, before I try to figure out which assortment of bins to put out for tomorrow, I thought I’d do a quick blog about this blog.

Once upon a time, in the good old days, in the dim and distant past, WordPress used to publish an annual statistical summary page for its bloggers, but it has discontinued that practice so now I’ll just write my own brief summary based on the data available via the usual dashboard.

For those interested I got about 425K hits this year, just over 1160 a day, with about 221K unique views. That’s up a bit since last year. In fact 2018 has been the busiest year on here since 2014. Interestingly, a much larger proportion of traffic was from the USA in 2018 than in any previous year.

In 2018 there were 2625 comments on this blog, similar to 2017. No prizes for guessing who wrote the most comments. Posts received 1153 ‘likes’ during the course of the year.

Altogether, since this blog started in 2008 to the end of 2018, it has been viewed 3,795,323 times by a total of 1, 315,185 unique visitors (though, obviously, all my visitors are unique). On this basis I’d expect my 4,000,000th read sometime during 2019.

It just remains for me to pass on a message from my employer.

I’ll be back at work on Friday!

New Year Honour

Posted in Beards, Biographical, Cardiff with tags on December 29, 2018 by telescoper

The New Year Honours List for 2019 has been published and I find that once again I have been denied the opportunity to turn down an award.

I find more than adequate compensation, however, in the award of Beard of the Year 2018. I was presented with the Certificate in Tiny Rebel Cardiff by Beard Liberation Front organiser and spokesbeing Keith Flett (left; picture by Megan Davies)

The certificate mentions a joint award but I am yet to receive the joint.

Anyway here is the certificate in close up.

Although I saw I was doing well in the popular vote, I was surprised be a winner as I thought it would be given to someone with a higher public profile than me. Happily, for me anyway, the Electoral College decided in my favour.

We bumped into two members of the School of Physics & Astronomy at Cardiff University in Tiny Rebel (both of whom, I must say, appeared to be rather the worse for drink). A short discussion arose as to whether Beard of the Year could be submitted as evidence of ‘impact’ for the forthcoming Research Excellence Framework. I was working at Cardiff for about half the period covered by the award, you see. I’ll leave that as a matter for the relevant authorities to decide.

Scientists win People’s Vote for Beard of the Year for the first time

Scientists win People’s Vote for Beard of the Year for first time

The Beard Liberation Front the informal network of beard wearers, has said that after a record vote for the Beard of the Year 2018 the Electoral College has determined that two scientists are the winners. TV doctor Xand Van Tulleken and cosmologist Peter Coles currently at Maynooth University in Ireland shared the Award.

The campaigners say that both the winners had an enthusiastic voting constituency and taking into account the public impact of their beards it was felt a shared title was appropriate this year.

Moreover the fact that both have a scientific background for the first time reflects the growing reach of beard wearing.

Manchester brewer Al Wall of leading craft brewery Cloudwater was runner up with last year’s winner Jeremy Corbyn third.

Outward Bound

Posted in Biographical on December 22, 2018 by telescoper

So here I am, then half past seven in the morning and I’m in Dublin Airport waiting for a flight. I managed to drag myself out of bed in time for the 6am Airport Hopper and now I’m ready to fly.

I expected the airport to be very busy this morning with people departing for Christmas. The Hopper bus was certainly much busier than usual for a Saturday morning. The Airport, however, is nowhere near as bad as I’d expected so I managed to get through security and the rest in much less time than I thought.

I think my blogging is going to be at best intermittent over the next two weeks so I’ll take the opportunity afforded by the free airport wifi to wish you all a very merry Christmas (in Irish).

Messiah in Dublin

Posted in Biographical, Maynooth, Music with tags , , , , on December 14, 2018 by telescoper

On 10th December last year I posted a review of a performance of Handel’s Messiah in Cardiff. At the end of that item I wondered where I would be listening to Messiah in 2018. Well, the answer to that question turned out to be at the National Concert Hall in Dublin, the city where Messiah received its premiere way back in 1742.

Messiah was initially performed at Easter (on 13th April 1742) and it’s by no means clear (to me) why it ended up almost universally regarded as a Christmas piece. The work 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.

The printed programme for last night (cover shown above) included the first advertisement for the first performance of Messiah:

For the relief of the prisoners in the several Gaols and for the Support of Mercer’s Hospital in Stephen’s Street and of the Charitable Infirmary on the Inn’s Quay, on Monday 12th April will be performed at the Musick Hall in Fishamble Street, Mr Handel’s new Grand Oratorio MESSIAH…

The venue was designed to hold 600 people (less than half the capacity of the National Concert Hall) but 700 people crammed in. Ladies had been asked not to wear hoops in their dresses and gentlemen were asked not to bring their swords to help squeeze in the extra hundred. The concert raised the huge sum of £400 and Messiah was an immediate hit in Ireland.

It wasn’t the same story when Messiah was first performed in England the following year. It failed again in England when performed in 1745 but after some rewriting Handel put it on again in 1749 and it proved an enormous success. It has remained popular ever since. But it is still exceptionally popular in Dublin. There are umpteen performances of Messiah at this time of year, and the one I attended last night was one of three in the same week at the same venue, all more-or-less sold out. The Dubliners I chatted to in the bar before the concert were extremely proud that their city is so strongly associated with this remarkable work.

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, well 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.

Last night’s performance was by Our Lady’s Choral Society with the RTÉ Concert Orchestra. Soloists were Sarah Brady (soprano), Patricia Bardon (mezzo), Andrew Gavin (tenor) and Padraic Rowan (bass), the latter really coming into his own in the second half with a wonderfully woody sonority to his voice, especially in No. 40:

Why do the nations so furiously rage together, and why do the people imagine a vain thing?

Topical, or what?

Our Lady’s Choral Society is an amateur outfit and, while it might not sound as slick and polished as some professional choirs, there was an honesty about its performance last night that I found very engaging. It actually sounded like people singing, which professional choirs sometimes do not. The orchestra played very well too, and weren’t forced to use the dreaded `period instruments’. There was a harpsichord, but fortunately it was barely audible. Anyway, I enjoyed the concert very much and so did the packed house. I couldn’t stay for all the applause as I had dash off to get the last train back to Maynooth, but that doesn’t mean I didn’t appreciate the music.

Incidentally, among the bass section of Our Lady’s Choral Society last night was my colleague Brian Dolan. On Monday next I’m going to another Concert at the National Concert Hall, Bach’s Christmas Oratorio. Among the choir for that performance is another of my colleagues, Jonivar Skullerud. Obviously, choral singing is the in-thing for theoretical physicists in this part of the world!

R.I.P. Pete Shelley (1955-2018)

Posted in Biographical, LGBTQ+, Music with tags , , on December 7, 2018 by telescoper

I heard the news late last night of the passing of Pete Shelley, best known as the lead singer of the Buzzcocks. Another iconic figure from my youth has gone. I was never really interested in the 70s punk movement in the UK, but the Buzzcocks managed to combine some of the energy and directness of punk rock with more conventional pop melodies. Above all, though, there was Pete Shelley’s style of delivery, head tilted to one side, a unique mixture of queer camp and unapologetic defiance. That had a big effect on me in my teenage years. In particular, I remember watching watching this performance on Top of the Pops in 1978 (forty years ago, when I was 15) and understanding exactly what the song was about. Ever Fallen In Love only got to number 12 in the charts, but in my memory it was a far bigger hit than that.

Rest in peace, Pete Shelley (1955-2018).

P.S. The answer to the question posed in the song is, of course, `yes’..
