Follow @telescoperThe observant among you will have noticed that the website for the Open Journal of Astrophysics is currently offline. This emphatically does not mean that this project is dead so
In fact we’re in the process of moving the journal to a new platform (at the same web address) and the new site will be up and running as soon as we have completed the transfer, have tested the new configuration and done a few administrative things. All papers already published on the old site will be transferred to the new one and their DOI will remain unchanged. In fact the old site is still available, but at a secret location.
I’ll be blogging in a bit more detail about the new-look Open Journal of Astrophysics in due course, but in the mean time I’ll just make a few points.
First and foremost, if you don’t know what this project is about it is an idea I first floated over five years ago, shortly before I moved to Sussex. Although we got a website together and published a few papers, for one reason or another I didn’t have time to iron out some remaining bugs and the project stalled. However, after my move to Maynooth University I’ve been delighted to receive the support of the Maynooth University Library team and we’re now moving ahead. I know there have been a few false dawns on this project – for which I apologize – so I won’t announce the full re-opening until I’m absolutely sure everything works.
Second, and actually most importantly, the Editorial Board for the Open Journal of Astrophysics is looking for new members. We already have several distinguished editors, but the expertise we currently have is concentrated (not surprisingly) in cosmology, and we would really appreciate volunteers from other areas of astrophysics (especially stars/exoplanets, etc). If you’re interested please let me know.
Third, although the platform will look a little different (i.e. better) the overall philosophy of the Open Journal will remain as it always was, a fully `Green’ Open Access Journal, as defined by the following points:
Finally, I will mention that I was motivated to post this update by a piece by George Monbiot in todays’s Guardian. I don’t agree with everything Monbiot says, but he is dead right about this:
In the great majority of cases, the research reported has been funded by taxpayers. Most of the work involved in writing the papers, reviewing and editing them is carried out at public expense by people at universities. Yet this public asset has been captured, packaged and sold back to us for phenomenal fees. Those who pay most are publicly funded libraries. Taxpayers must shell out twice: first for the research, then to see the work they have sponsored. There might be legal justifications for this practice. There are no ethical justifications.
I’ve said as much myself on this blog. My point is that the academic publishing industry is not going to change of its own volition. If the Academic Journal Racket is to be rumbled, it is we (by which I mean academics and our institutions) who have to take control. Sitting on our hands while we get systematically fleeced is not an option. One way to do this is for institutions and organizations to themselves become Open Access publishers, which is precisely what my current institution is doing: Maynooth University will be the official publisher of the Open Journal of Astrophysics (and hopefully many more similar journals in the future).
Follow @telescoperThere is an interesting, pithy and polemical paper on the arXiv by David Mermin, with the abstract:
We still lack any consensus about what one is actually talking about as one uses quantum mechanics. There is a gap between the abstract terms in which the theory is couched and the phenomena the theory enables each of us to account for so well. Because it has no practical consequences for how we each use quantum mechanics to deal with physical problems, this cognitive dissonance has managed to coexist with the quantum theory from the very beginning. The absence of conceptual clarity for almost a century suggests that the problem might lie in some implicit misconceptions about the nature of scientific explanation that are deeply held by virtually all physicists, but are rarely explicitly acknowledged. I describe here such unvoiced but widely shared assumptions. Rejecting them clarifies and unifies a range of obscure remarks about quantum mechanics made almost from the beginning by some of the giants of physics, many of whom are held to be in deep disagreement. This new view of physics requires physicists to think about science in an unfamiliar way. My primary purpose is to explain the new perspective and urge that it be taken seriously. My secondary aims are to explain why this perspective differs significantly from what Bohr, Heisenberg, and Pauli had been saying from the very beginning, and why it is not solipsism, as some have maintained. To emphasize that this is a general view of science, and not just of quantum mechanics, I apply it to a long-standing puzzle in classical physics: the apparent inability of physics to give any meaning to “Now” — the present moment.
The `new perspective’ Mermin espouses is a form of `QBism (i.e. `Quantum Bayesianism’)‘. You can download the full article for free here.

I was very sad last night to hear news of the death, at the age of 90, of the sublime Fenella Fielding. There was much more to Fenella Fielding than the Carry On films – she only appeared in two, but everyone will remember her as Valeria in the hilarious spoof horror movie Carry on Screaming with the classic gag “Do you mind if I smoke?”
R.I.P. Fenella Fielding (1927-2018).
Follow @telescoperWell, with the Last Night of the Proms over and done with on Saturday, and the last day of the Fifth Test between England and India just finished at the Oval, that’s the end of the summer as far as I’m concerned.
I thought for a while earlier today that India might just pull off a remarkable victory. Needing 464 to win they were going well as Rahul and Pant put on a 200 partnership. I saw that BetFair were offering 16/1 on an India victory so put a tenner on. That had the desired effect and India were all out for 345. Good effort though by India. Especially well, played by Pant, on his maiden century!
Oh, and Jimmy Anderson took the last wicket, his 564th in Test cricket, and thereby beat Glenn McGrath’s record as leading pace bowling wicket-taker of all time in Test matches.
The 4-1 margin of victory in this series rather flatters England and is correspondingly harsh on India. The big worry for England is that with Cook now in retirement they now have to find two reliable opening batsmen when so far they’ve failed to find one.
Anyway, tomorrow morning I’m back to Maynooth. I have a paper and a book manuscript to submit before getting my lectures ready for the new term.
After receiving some very good news today, there is also a big event to prepare for on October 9th of which more anon..

Back in Cardiff for a short visit, I thought I’d make the most of what remains of my season ticket to watch the morning’s play at Sophia Gardens between Glamorgan and Gloucestershire.
It being September, play commenced at 10.30 after an uncontested toss. Gloucestershire invited Glamorgan to bat first. In humid conditions, under overcast skies, and against a team lacking confidence, it was a predictable decision.
Connor Brown was the first Glamorgan batsman to go, lbw playing back to one that might have kept low. A few overs later Tom Cullen inexplicably shouldered arms to a straight delivery that hit the top of middle stump. Kieran Carlson went first ball to a very good delivery from Payne, and then Stephen Cook was caught behind down the leg side off one that bounced sharply and took the glove. That made it 17 for 4, which became 21 for 5 when David Lloyd was lbw to Payne.
To be fair to the batsmen the ball was darting around a bit, and batting didn’t look at all easy. All the same it looked like another sorry capitulation.
Wicketkeeper Chris Cooke had other ideas, however, and he and Graham Wagg out together a good counterattack. Cooke reached 50 having hit 11 fours, and their partnership was worth 83 valuable runs. Cooke was out before lunch for 60, caught behind off the bowling of Payne.
Glamorgan went into lunch at 109 for 6, having recovered somewhat from 21 for 5. I left at lunchtime to take care of some personal things. When I checked just now, Glamorgan were all out for 137, heading for their 9th consecutive defeat.
Meanwhile, at the Oval, Alastair Cook has scored a century in his final Test Match. Well played sir!
UPDATE: I went back to the ground after the tea interval, and saw Gloucestershire progress to 133 for 5. It never looked easy batting, and there were quite a few edges that fell safe and quite a lot of playing and missing, but no great collapse by the visitors. The weather forecast for tomorrow is a bit grim so that is probably the last cricket I’ll see at Sophia Gardens as a Glamorgan member. Best wishes to the players and all the staff at the ground.
Follow @telescoperAs the Test cricket season in England draws to a close I thought I might do a post summarising my extensive contributions to the comments section of the BBC Test Match Special website.
Here they both are:


The first was posted just before the start of play on the first day of the 4th Test between England and India. It turned out to be rather prescient. The second appeared earlier today, during the third day of the Fifth Test.
I think it was Andy Warhol who said that one day everyone will have a comment on the TMS web page. At any rate, that’s probably the closest I’ll ever get to 15 minutes of fame..

In Dublin Airport, as in most other European Airports these days, WH Smith has a monopoly on the sale of printed matter, including newspapers. This morning, then, on my way back to Wales and wanting something to read, and a crossword to do, on the flight, I picked up a copy of the Weekend FT and took it to the automatic checkout.
As you can see, the newspaper is clearly marked ‘Republic of Ireland €4. 00’ (the price has just gone up). I scanned it on the machine and was about to pay when I noticed the price had come up as €5.70. Querying this apparent error with the assistant I was told this was the price I would have to pay because “this is the airport”.
I refused, and bought the Irish Times instead. That was marked €3.20 on the banner, the same amount as I was charged. I eventually bought the FT when I got back to Cardiff. The crossword was quite easy.
I don’t know of it’s unlawful in Ireland to attempt to sell goods at higher than the marked price, but it’s certainly sharp practice to do it surreptitiously, as Smith’s have done, in such a way that many people will pay without noticing the fact that they have applied a 42.5% markup. But then this company has a reputation for dodgy business practices, forcing small newsagents and bookshops out of the High Street and replacing them uniformly dreary outlets selling overpriced low quality items. You will struggle to find a decent bookshop in any airport because of the Curse of WH Smith.
Perhaps, after Brexit, WH Smith will lose its monopoly but I’m not waiting for that to make a decision not to shop there again.
Follow @telescoperToday I’ve been trying to finish off a couple of things before making a short trip back to Cardiff to sort out of a few personal matters. Next week the new intake of students starts to arrive in Maynooth. Officially Welcome Week begins on 17th September but in the second half of next week there are `Orientation Talks’ aimed at guiding new students through all the options they have in the first year. The flexibility of the degree programmes here really makes these talks essential.
Yesterday I blogged about some of the differences between the Higher Education systems in Ireland and the United Kingdom. Another couple came up today. The first is that `Orientation’ over here is what UK universities usually call `Induction’. One thing is common to both systems, though. When I made my annual `joke’ about `induction’ involving passing the students through a magnetic field in order to establish their potential, it fell just as flat here as it always has done on the UK.
Another difference is that over here we don’t have graduation ceremonies; they are called conferring ceremonies. On University Challenge there is no conferring. Moreover, the ceremonies are not in July (as graduation ceremonies usually are in the UK). In fact there are three sets of ceremonies, in mid-September, late October/November, and March. The first set is next week actually. That means I won’t be able to bore my readership with explanations of the Latin grammatical origins of the words graduand and graduate as I have done in the past.
Finally, I just wanted to mention that there is a site called Ninth Level Ireland which aggregates news items, blogs and other online items about Higher Education in Ireland. That site started reblogging my posts long before I moved to Ireland, actually. I know quite a few Irish academics follow Ninth Level Ireland , and if you’re interested in matters academical then it’s well worth looking at. As you can see, it even uses the same WordPress theme as this blog.
I don’t know whether it is automated (like a `bot’) or whether items are selected by hand, but if it’s the former I suspect this post might well end up the site!
Follow @telescoperA few people have asked me to comment a little bit on difference between Higher Education Institutes in the United Kingdom and here in Ireland from the point of view of teaching and learning. I can’t do that systematically of course because I’ve only ever been at one University in Ireland, Maynooth, and that for only a year. I have however held positions that involved teaching in several UK universities (Queen Mary, Nottingham, Cardiff and Sussex) so perhaps some comments based on my own experiences might be useful. And of course I’m just talking about Theoretical Physics here, so I won’t discuss labs. It’s a very big selling point for our Theoretical Physics courses here that students don’t have to do labs (apart from Computational Physics labs, of course).
To start with something rather trivial, the `load’ for a student in most UK universities is usually 120 credits while here in Ireland it is 60. The actual workload expected of a student is the same so this just means there’s an exchange rate of 2:1 between the UK and Ireland. In the UK the load is usually split into two equal semesters with examinations in January and May after each. In the UK the 60 credits of each semester is usually split into modules. In my experience in physics these can be either 10 or 20 credits (e.g. Cardiff) or 15 credits (e.g. Sussex). The standard size here in Maynooth is 5 credits (equivalent to 10 in the UK), so most comparisons will be with a standard 10-credit module based on the Cardiff model (which I think is more common than the Sussex model).
What goes into these standard modules differs slightly. Here in Maynooth there are twelve teaching weeks per semester plus a `Study Week’ half way through, so each is 13 weeks long. For a 5-credit module there are usually two lectures per week (so 24 in total, as there are no lectures in Study Week). On top of this there are weekly tutorials (usually done by PhD students). In Cardiff there are also 2 lectures a week for the directly comparable 10 credit module, though not all modules have tutorials associated with them. There is no mid-term Study Week in Physics & Astronomy at Cardiff and teaching term is only 11 weeks, so students typically have 22 lectures in a `standard’ module.
Continually-assessed coursework at Maynooth typically counts for 20% of a module mark (as it does in Cardiff), with 80% on an examination. In both Cardiff and Maynooth a `standard’ module has a two-hour examination at the end, but there’s a big difference in style: most of the papers in Maynooth require students to answer all the questions for full marks, whereas in Cardiff it’s two out of three or three out of four (usually). The Maynooth style makes it much harder for students to question-spot.
In summary, then, the amount of contact time for a student in Maynooth is greater than in Cardiff. The student-staff ratio in the Department of Theoretical Physics in Maynooth is about 15, which is a little higher than most UK physics departments (see Table here). There are only 7 full-time academic staff with full curriculum to deliver, means that teaching loads here are quite heavy compared to the UK.
Four modules per year is typical.
That might seem a lot to some people, but I actually enjoy teaching so don’t mind at all. In fact, with the mountain of administrative stuff I had to do at Sussex, it was only the fact that I taught a full module (on Theoretical Physics) that kept me (partially) sane. This year I shall be teaching, in the Autumn Semester, a 4th-year module on Astrophysics & Cosmology and a 2nd-year module on Vector Calculus and Fourier Series and, in the Spring Semest, 3rd-year Computational Physics 1 (again) and Engineering Mathematics (for First-year engineers). I’m not sure what to expect of that last one, but I’m not going to think about it until the New Year.
Most of our students do a four-year Bachelors programme in Science (as discussed briefly here) with a very general first year. Some, however, come directly into a programme called Theoretical Physics & Mathematics (TP&M, for short) which is three-year fast-track degree. It’s harder to get into TP&M than the `Omnibus’ Science course, but it does attract some very capable students.
I should mention that the really big difference between Ireland and the UK is that the system of teaching and learning here is much less centralized and much less rigid that UK universities. The small size of the Department means that it is possible to know all the students by name and students with difficulties can always find someone to talk to. That is increasingly not the case in UK universities, which are rapidly turning into teaching factories and are subject to the pressure to do well in league tables (often with a negative impact on teaching quality).
Subject to some conditions, first-time full-time undergraduate students in `Third-level’ education in Ireland do not pay tuition fees as such, and neither do students from other EU or EEA countries. There is however an annual ‘student contribution’ of €3000 which all students pay (unless they have a grant that covers it). As far as I can see, that is effectively a fee, though it is supposed to cover student services (e.g. libraries) and examinations rather than tuition. Students taking repeat examinations generally have to pay extra for them. If you consider the `student contribution’ to be a fee (which is effectively what it is) then the Irish funding system is similar to the pre-2012 UK system, i.e. before the introduction of the current £9K fee.
Finally, one of the most striking differences between Ireland and the UK is that here a much higher proportion of students live at home with their parents while studying and commute into campus daily (some of them from quite a distance). That is quite unusual in the UK, but is fairly typical in other EU countries (e.g. Italy). The cost of accommodation is undoubtedly a factor, but I think it’s also a more general cultural thing. I’ve also noticed something here that I’ve never seen in the UK, which is that some student accommodation is let on a Monday-Friday basis, the tenant being expected to go back to the parental home at the weekends. On Fridays in term-time, you can see quite a lot of students with their bags waiting for coaches or trains to take them away for the weekend…
In a future post I might comment on non-academic differences between Ireland and the UK (e.g. tax, public services, cost of living, etc) but I think that will do for now.
