Open Journal of Astrophysics Impact Factor Poll

Posted in Open Access with tags , , on February 5, 2021 by telescoper

A few people ask from time to time about whether the Open Journal of Astrophysics has a Journal Impact Factor.

For those of you in the dark about this, the impact factor for Year N, which is usually published in year N+1, is based on the average number of citations obtained in Year N for papers published in Years N-1 and N-2 so it requires two complete years of publishing.

For the OJA, therefore, the first time an official IF can be constructed is for 2021, which would be published is in 2022 and it would be based on the citations gained in 2021 (this year) for papers published in 2019 and 2020. Earlier years were incomplete so no IF can be defined.

It is my personal view that article-level level bibliometric data are far more useful than journal-level descriptors such as the Journal Impact Factor (JIF). I think the Impact Factor is very silly actually. Unfortunately, however, there are some bureaucrats that seem to think that the Journal Impact Factor is important and some of our authors think we should apply to have an official one.
What do you think? If you have an opinion you can vote on the twitter poll here:

I should add that my criticisms of the Journal Impact Factor are not about the Open Journal’s own citation performance. We have every reason to believe our impact factor would be pretty high.

Comments welcome.

Language Lessons

Posted in History, Irish Language, Maynooth with tags , , , , , , , , , , on February 4, 2021 by telescoper

Thursday is Computational Physics Day this term so this morning I delivered the first Panopto lecture of that module and in the afternoon we had our first laboratory session. The students are all at home of course so we had to run the lab with them using their own laptops rather than the dedicated Linux cluster we have in the Department and interacting via Microsoft Teams.  The first lab is very introductory so it was really just me presenting and them following on their machines without too much interaction. The ability to share a screen is actually very useful though and I imagine using it quite a lot to share Spyder. It went fairly well, I think, with all the students getting started out on the business of learning Python.

In between lecturing the morning and running the laboratory session this afternoon I had the chance to study another kind of language. Soon after I first arrived in Maynooth I got an email from Maynooth University about Irish language classes. Feeling a bit ashamed about not having learned Welsh in all my time in Cardiff, I thought I’d sign up for the Beginners class and fill in a Doodle Poll to help the organizers schedule it. Unfortunately, when the result was announced  it was at a time that I couldn’t make owing to teaching, so I couldn’t do it. That  happened a couple of times, in fact. This year however I’ve managed to register at a time I can make, though obviously the sessions are online.

I’m not sure how wise it is for me to try learning a new language during a term as busy as this, but I have to say I enjoyed the first session enormously. It was all very introductory, but I’ve learnt a few things about pronunciation – unsurprisingly the Irish word for pronunciation fuaimniú is unsurprisingly quite difficult to pronounce – and the difference between slender and broad vowels. I also learnt that to construct a verbal noun, instead of putting -ing on the end as you would in English, in Irish you use the word ag in front of the verb.

That’s not to say I had no problems. I’m still not sure I can say  Dia duit (hello) properly. The second “d” is hardly pronounced. 

Irish isn’t much like Welsh, which I failed to learn previously.  Although Irish and Welsh are both Celtic languages they are from two distinct groups: the Goidelic group that comprises Irish, Manx and Scottish Gaelic; and the Brythonic group that comprises Welsh, Cornish and Breton. These are sometimes referred to as q-Celtic and p-Celtic, respectively, although not everyone agrees that is a useful categorization. Incidentally, Scottish Gaelic is not the language spoken by the Celtic people who lived in Scotland at the time of the Romans, the Picts, which is lost. Scottish Gaelic is actually descended from Middle Irish. Also incidentally, Breton was taken to Brittany by a mass migration of people from South-West Britain fleeing the Anglo-Saxons which peaked somewhere around 500 AD. I guess that was the first Brexodus.

Welsh and Irish don’t sound at all similar to me, which is not surprising really. It is thought that the Brythonic languages evolved from a language  brought to Britain by people from somewhere in Gaul (probably Northern France), whereas the people whose language led to the Goidelic tongues were probably from somewhere in the Iberia (modern-day Spain or Portugal). The modern versions of Irish and Welsh do contain words borrowed from Latin, French and English so there are similarities there too.

Only a diacritic mark appears in Irish, the síneadh fada (`long accent’), sometimes called the fada for short, which looks the same as the acute accent in, e.g., French. There’s actually one in síneadh if you look hard enough. It just means the vowel is pronounced long (i.e. the first syllable of síneadh is pronounced SHEEN). The word sean (meaning old) is pronounced like “shan” whereas Seán the name is pronounced “Shawn”.

One does find quite a few texts (especially online) where the fada is carelessly omitted, but it really is quite important. For example Cáca is the Irish word for `cake’, while the unaccented Caca means `excrement’…

I took the above text in Irish and English from the front cover of an old examination paper. You can see the accents as well as another feature of Irish which is slightly similar to Welsh, the mysterious lower-case h in front of Éireann. This is a consequence of an initial mutation, in which the initial character of word changes in various situations according to syntax or morphology (i.e. following certain words changing the case of a noun or following certain sounds). This specific case is an an example of h-prothesis (of an initial vowel).

In Welsh, mutations involve the substitution of one character for another. For example, `Wales’ is Cymru but if you cross the border into Wales you may see a sign saying Croeso i Gymru, the `C’ having mutated. The Irish language is a bit friendlier to the learner than Welsh, however, as the mutated character (h in the example above) is inserted in front of the unmutated character. Seeing both the mutated and unmutated character helps a person with limited vocabulary (such as myself) figure out what’s going on.

Mutations of consonants also occur in Irish. These can involve lenition (literally `weakening’, also known as aspiration) or eclipsis (nasalisation). In the case of eclipsis the unmutated consonant is preceded by another denoting the actual sound, e.g. b becomes m in terms of pronunciation, but what is written is mb. On the other hand, lenition is denoted by an following the unmutated consonant. In older forms of Irish the overdot (ponc séimhithe) -another diacritic – was used to denote lenition.

Anyway, I’ve seen Dia duit written Dia dhuit which might explain why the d sounds so weak. We live and learn. If I keep at it long enough I might eventually be able to understand the TG4 commentary on the hurling..

Old and New Dreams

Posted in Jazz with tags , , , , , , on February 3, 2021 by telescoper

I was just relaxing by listening to the superb album Old and New Dreams (vintage 1977) and thought I’d share a track here given the ongoing prevalence of lockdown dreams. This album was actually the debut album by the Quartet of the same name that featured Dewey Redman on tenor sax, Don Cherry on trumpet, Charlie Harden on bass and Ed Blackwell on drums. I love the balance they achieved between free improvisation and swing and the interplay between the different instruments. Just listen to Charlie Haden’s playing on this, holding everything together rhythmically but also leading it in so many different directions! This is called Augmented

Teaching from Home

Posted in Covid-19, Education, Maynooth on February 3, 2021 by telescoper

Determined to follow the public health advice and work from home I decided to set up a blackboard in my study so I can do lectures online. I find the blackboard shows up better on camera than a whiteboard and using this arrangement allows me to stand up while I deliver the material, which I find much more comfortable than sitting down.

I’m fortunate of course in having enough space to do this. Not every University lecturer can do this.

The bit you see on the board was the start of my second Engineering Mathematics lecture to first-year students. I had asked the students at the end of Lecture 1 to think about the Laplace Transform of f(t)=t and began Lecture 2 by going through the necessary integration on the board.

Today I have three lectures – another Engineering Maths and two Advanced Electromagnetism to give so the board will be more extensively used. I just hope my internet connection stays up!

P. S. Playing back today’s videos I have discovered an optical defect in the Panopto system that makes my hair look grey.

P.P.S. Three lectures in an afternoon (12-1, 2-3 and 4-5) is quite hard work but at least I had breaks between them!

New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , on February 2, 2021 by telescoper

Time to announce the first publication of 2021 in the Open Journal of Astrophysics. This one was actually published a few days ago but  it took a bit of time to get the metadata and DOI registered so I held off announcing it until that was done.

The latest publication is a lengthy and comprehensive review article (67 pages altogether) by Allahverdi et al. which has 26 authors from all round the world. It is entitled The First Three Seconds: a Review of Possible Expansion Histories of the Early Universe and is a study of the various possible evolutionary histories of cosmic expansion possible with a wide range of cosmological models with their implications for baryogenesis, nucleosynthesis, primordial gravitational wave production, and many other things besides.

Here is a screen grab of the overlay:

You can click on the image to make it larger should you wish to do so. You can find the arXiv version of the paper here. This is one for the Cosmology and Nongalactic Astrophysics folder.

And so Volume 4 begins. Volume 3 had 15 papers, Volume 2 had 12 , and Volume 1 just 4 so we’re growing slowly but surely! Let’s see how many we publish in 2021. I can tell you  we have some very exciting papers in the pipeline…

The Start of Spring Semester

Posted in Biographical, Education, Maynooth with tags , , , , , , , on February 1, 2021 by telescoper

It’s February 1st 2021, which means that today is Imbolc, a Gaelic festival marking the point halfway between the winter solstice and vernal equinox, i.e. it’s a Cross-Quarter Day. To be pedantic, Imbolc is actually the period between this evening and tomorrow evening as in the Celtic calendar days were counted from sunset to sunset.

The first Day of February is also the Feast day of St Brigid of Kildare (c. 451-525), one of Ireland’s patron saints along with Saints Patrick and Colm Cille. One of her miraculous powers was the ability to change water into ale, which perhaps explains her enduring popularity among the Irish.

In Ireland this day is sometimes regarded as the first day of spring, as it is roughly the time when the first spring lambs are born. It corresponds to the Welsh Gŵyl Fair y Canhwyllau and is also known as the `Cross Quarter Day’ or (my favourite) `The Quickening of the Year’. According to legend it is also the day on which jackdaws mate. Given how many of them there are around Maynooth there should be a lot of action today.

Today is, appropriately enough in the light of all this, the start of the Spring Semester of teaching at Maynooth University, the fourth Spring Semester I will have experienced here although this is obviously not like the others in that we’ll be teaching online at least for the first half and probably for the entirety. I was planning to stay at home today but I realised I’d left some things I need in the office on campus so will have to go to collect them. That’s why I’m up early. That and the need to shake myself out of the lockdown torpor that has afflicted me since New Year. It’s time to get my act together, pull my finger out, put my best foot forward, etc.

This Semester I am teaching Engineering Mathematics II, Computational Physics I and Advanced Electromagnetism. The former, what you would probably call a `service course’, covers a mixture of things, mainly Linear Algebra but with some other bits thrown in for fun, such as Laplace transforms. Interestingly I find the Mathematical Physics students do not encounter Laplace Transforms in the first year, but perhaps engineers use them more often than physicists do? I think I’ve written only one paper that made use of a Laplace transform. Anyway, I have to start with this topic as the students need some knowledge of it for some other module they’re taking this semester. I reckon six lectures will be enough to give them what they need. That’s two weeks of lectures, there being three lectures a week for this module.

Once again my teaching timetable for this module is quite nice. I have lectures on Monday, Tuesday and Wednesday and then the students have a choice of tutorial (on either Thursday or Friday). That means I can get through a decent amount of material each week before each tutorial. I don’t do the tutorials, by the way: that’s left to one of our PhD students, who gets paid for doing that and correcting the weekly coursework. There are about 50 students on this module, divided into two courses: Electronic Engineering and Robotics and Intelligent Devices. We don’t have Civil or Mechanical or Chemical Engineering, etc, at Maynooth, in case you were wondering. Lectures will be done as webcasts using Panopto but also recorded for later viewing.

My first Computational Physics lecture, which I will do from home, is on Thursday, after which there is a lab session which we will do via Microsoft Teams. That’s the way we did it after lockdown last year and it worked OK. Students attend one two-hour lab session in addition to the lecture, on either Thursday or Tuesday. The first lecture being on Thursday the first lab session will be Thursday afternoon, with the same material being covered the following Tuesday. Fortunately, Python is free to download and easy to install so it’s quite straightforward to run the labs remotely. Teams has a screen sharing facility so it’s quite easy for myself or my demonstrator to see what is wrong in the same way we would do in a laboratory class.

The Advanced Electromagnetism module is a new one for me but I’m quite looking forward to it. Being a final-year module its content is less prescriptive than others and I’ll be adding a few things that I find interesting. Both lectures for that one are on Wednesdays and again will be given as webcasts with recordings available later.

Today is a particularly busy day because in addition to my first lecture (at 2pm) I have a meeting of Academic Council (3pm via Teams), a Euclid telecon (via Zoom) and a meeting with my PhD student via Teams. I have also been trying to sort out tutors and tutorials for the forthcoming Semester: these don’t start until next week so there’s time, but it has been quite a challenge to get everyone sorted. Fortunately I think that’s now done.

Oh, and another thing. I signed up for Irish language lessons (Beginners Level) and will be having classes once a week from now on.

It’s going to be a very busy term but I reckon being busy is probably going to be a good way to get through the next few months.

It’s A Sin – Pet Shop Boys

Posted in Biographical, Music with tags , , , on January 31, 2021 by telescoper

I couldn’t resist posting this, given the impact of the TV series of the same name. If you’re following It’s A Sin you will find this track featured in Episode 4 which is set in 1987, when this track was released. Quite a lot of 80s synth-pop sounds rather dated to me nowadays but this doesn’t at all.

Rather than being directly about the AIDS crisis it’s really Neil Tennant‘s general reaction to his Catholic upbringing, hence the section of the Confiteor that you can hear from time to time:

Confiteor Deo omnipotenti vobis fratres quia peccavi nimis cogitatione, verbo, opere et omissione. Mea culpa, mea culpa, mea maxima culpa.

Although I wasn’t brought up a Catholic – and have therefore never been very good at guilt – the lyrics still have an impact:

When I look back upon my life
it’s always with a sense of shame
I’ve always been the one to blame
For everything I long to do
no matter when or where or who
has one thing in common too

It’s a, it’s a, it’s a, it’s a sin
It’s a sin
Everything I’ve ever done
Everything I ever do
Every place I’ve ever been
Everywhere I’m going to
It’s a sin

In fact, Neil Tennant went to St Cuthbert’s Roman Catholic Grammar School, literally just yards from where I grew up in Benwell in Newcastle upon Tyne.  Given his age – he was born in 1954 – he would have been there while I was living in Benwell Village, though obviously we never met.

The video was directed by Derek Jarman who died from AIDS in 1994.

 

My Acting Career

Posted in Biographical, Brighton, LGBTQ+, Mental Health, Television with tags , on January 30, 2021 by telescoper

Out of the swirling mass of cathartic memories unleashed by watching It’s A Sin there suddenly popped this one which had been buried away in the dark recesses of my subconscious for over thirty years.

Oh no, I can hear you thinking, not another one of those tediously self-indulgent posts. It’s not like that, actually. I decided to share it mainly because I think it’s quite funny!

When I was living in Brighton in the late 1980s I and a friend of mine decided to try a spot of amateur dramatics. I can’t remember what the play was – because neither of us succeeded in getting involved – but it seemed like it would be interesting so responding to an advert in a local newspaper we turned up for the audition.

The first bit was a reading. My choice of piece was a bit unusual. I did a bit of drama at school, but since I went to a single-sex grammar school all the female parts were played by boys, which is why I ended up playing Lady Scottish Play in the Scottish Play. I remembered some of Mrs M’s speeches – an do to this day – so did for my audition piece the one that begins “The Raven himself is hoarse…” and has bits about “unsex me here”, etc.

Surprisingly I got through the reading bit.

For the next part all the survivors (about 15 of us) sat in chairs on the stage. The Director bloke then announced that he wanted us to “act” somebody crying. I sat for a moment, then looked at the others, who were making what I thought were very hammy attempts to do a cry and I thought to myself “I can do better than that”.

I may have been quite young then, but I’d quite recently been beaten up, spent weeks in a psychiatric hospital, and seen two friends die from AIDS. I had, therefore, under the surface, acquired quite a reservoir of sadness to draw on. I’m not a trained method actor or anything like that but I knew that I could summon up something very easily. So that’s what I did. I shut my eyes and thought for a moment, and started crying my eyes out. The group of prospective actors around me all stopped and stared.

Eventually the Director came on stage looking very concerned and asked if I was all right. I said “Yes. I’m fine. I thought you you wanted us to cry.” He looked amazed.

The audition ended and I assumed I had wowed everyone enough with the deep emotion of my performance to get the part. On the way out, though, I was told that I hadn’t passed the audition.

The reason given was that it’s absolutely no good portraying grief or pain in a theatre – even a small one – by sitting in a chair actually crying. The audience won’t really see the tears, so you have to do a lot more with gestures and movement.

The production went ahead without me in it, and I’ve thought so little of it until now that I’ve even forgotten what the play was!

It’s not much of a talent to be able to turn on the waterworks on demand, but I thought I’d share this experience here to point out (a) that I can still do it and (b) if there are any TV or film directors looking to cast a (hopefully lucrative) role for a middle aged guy who can cry in close up and is not required to do much else then they need look no further!

Perhaps I should hire an agent?

Maynooth and the Boyle Family

Posted in History, Maynooth, The Universe and Stuff with tags , , , , , , , on January 30, 2021 by telescoper

It’s a rainy Saturday afternoon in Maynooth and I don’t feel like taking my usual walk so I thought I’d post another bit of local history like I did last week. This is another thing I’ve just found out and thought I’d share. This is a view I took last spring of Maynooth Castle (or the ruins thereof):

The Castle, together with a Manor House that was next to it, belonged to the Fitzgerald family, local aristocracy since the 13th Century. As I mentioned in a previous post, Thomas Fitzgerald, the 10th Earl of Kildare, led a rebellion against the English authorities during the time of Henry VIII. He acquired the nickname “Silken Thomas” because of the ribbons of silk worn by his supporters. The rebellion failed and his family castle was badly damaged. Thomas surrendered and was subsequently executed, along with several members of his family, in 1537. The family fortunes declined pretty drastically at that point but the family line did survive.

Now fast forward to 1630 when George Fitzgerald, the 16th Earl of Kildare married a Lady Joan Boyle. She was the daughter of a tremendously powerful figure by the name of Richard Boyle, the 1st Earl of Cork. Richard Boyle had been part of the Tudor plantation of Ireland and had acquired enormous amounts of land and personal wealth in the process. He spent some of his riches at the time of his daughter’s wedding doing up the ancestral home of his son-in-law, refurbishing the castle and building a new manor house next to it.

Unfortunately this didn’t last long. During the Irish Confederate Wars the Castle was attacked several times and badly damaged. It remained in occupation but by the end of the 17th Century it was derelict. The Fitzgerald family eventually moved to a new home at the other end of Maynooth, Carton House (now an upmarket golf resort). All Richard Boyle’s refurbishment work went to nothing and all that survives to the present day – the Gatehouse and Solar Tower – dates to the 13th Century, no doubt because it was more solidly built.

I’ve known about this for quite a while, but only this morning I discovered something else. Richard Boyle had a very large family – fifteen children altogether – and his seventh son (14th child altogether) was none other than the famous natural philosopher Robert Boyle, after whom Boyle’s Law is named. He was a particularly important figure in the development of chemistry, paid for the publication of a translation of the Bible into Irish, was a founder member of the Royal Society of London and, more importantly than any of those things, wrote the book whose cover I use when I post rambling from In The Dark on Twitter:

It’s a very descriptive title for this blog, but perhaps not so catchy.

Anyway, largely because he found it difficult to acquire materials and equipment in Ireland, Robert Boyle spent most his scientific career in England. He did however return to Ireland a number of times. He was born in Lismore, in County Waterford, so probably would have stayed near there on these visit. It is entirely possible – and indeed likely – that he may have visited his sister in Maynooth while in Ireland.

Armchair Critic

Posted in Uncategorized on January 29, 2021 by telescoper

Following the success of yesterday’s post, which has received several hits, I have decided to become an armchair critic.

Take this one for example:

I quite like the shape, but the upholstery is awful.

Stay tuned for further reviews.
