Not Bad Godesberg

Posted in Biographical, Cricket with tags , , , , , , on June 10, 2018 by telescoper

Well, dear Readers, at this time I was supposed to be in Bad Godesberg, a municipal district of Bonn, in southern North Rhine-Westphalia in Germany for the 2018 Euclid Consortium Meeting which starts there tomorrow morning. To make sure I didn’t miss the opening sessions I booked a flight to Bonn/Cologne Airport from Heathrow at 8.50am today, and took the National Express Coach from Cardiff at 3.15am in order to make sure I arrived in good time for the flight.

Unfortunately, only 15 minutes after the Coach started on its way I got a text from the airline (a budget subsidiary of Lufthansa called `Eurowings’) had been cancelled. This was either to do with a strike of French Air Traffic Controllers or Thunderstorms; they never really got their story right. After a number of abortive attempts to rebook my flight using the coach’s wifi (e.g. to Frankfurt, whence by train to Bonn). I was advised that the system was overloaded and I should rebook at the airport.

Arriving at Heathrow Terminal 2 at 6.30, there was already a long line at the ticketing desk for Lufthansa/Eurowings. It got longer and longer as people arrived to find other flights had been cancelled too. When, after about 90 minutes in a queue, I finally got to a desk very few rebooking opportuninities were available, all of them involving silly routes (e.g. flying to Berlin, followed by a four and a half hour train trip to Bonn).

Exasperated, I suggested I could fly tomorrow instead if they offered to put me up in a hotel overnight. I didn’t fancy going back to Cardiff just so I could get up at stupid o’clock tomorrow to repeat the exercise. I’ll miss the first session of the meeting, but that’s not the end of the world.

So here I am, not in Bad Godesberg, but in the Holiday Inn at Heathrow Airport. I was booked in, given vouchers for lunch, dinner and breakfast tomorrow morning, and given two vouchers for the shuttle bus to and from Terminal 2. The hotel is characterless, but clean and the food is OK. I arrived about 10am and the room was available for me straight away, so I was able to catch up on a bit of sleep before watching most of Scotland’s memorable victory over England in today’s One Day International.

Now that I’ve had my free dinner (grilled Sea Bass) I am going to get some kip before getting up for my free breakfast and free trip back to the airport. The only question remains: will tomorrow’s flight be cancelled too?

Yet more sexual harassment in Astronomy

Posted in Uncategorized with tags , , on June 10, 2018 by telescoper

Yesterday I saw a thread on Twitter commencing with the following tweet by Dr Emma Chapman (now of Imperial College):

You can find the whole thread here; and here is one of the documents that have now been published:

I have met Dr Chapman and knew that she had endured sexual harassment in the recent past, but did not know any of the details of her case because they remained confidential until yesterday. They relate to sexual harassment by her PhD supervisor, Dr Filipe Abdalla of University College London (whom I don’t know personally). It has taken Dr Chapman two years to get documents relating to this case disclosed publicly. I also didn’t realise that episodes of harassment of other women were involved or that Dr Abdalla, who remains in post at UCL, has apparently been indulging in retaliatory behaviour towards those who have made complaints against his conduct. I am given to understand that Dr Abdalla is on a final written warning for his conduct.

I suggest you read the whole thread and form your own conclusions.

For what its worth, although I find it very hard to avoid the conclusion that University College London has handled this case abysmally at an institutional level, it is important to realise that failure to tackle sexual harassment properly is a systemic problem not confined to that particular institution. I know that the Department of Physics & Astronomy at UCL has fought very hard to tackle sexual harassment and discrimination, but efforts at such a level are not always helped by the attitudes of those in higher places.

I would like to take the opportunity to praise Emma Chapman for having the determination to get this out in the open (at considerable personal cost) and her legal advisors for finding a way through the wall of silence.

I have blogged a number of times before about sexual harassment cases, but I’ll take this opportunity to repeat what I said in an earlier post:

Failure to act strongly when such behaviour is proven just sends out the message that the institution doesn’t take sexual harassment seriously. In my view, confidentiality is needed during an investigation – to protect both sides and indeed the person doing the investigation – but if the conclusion is that misconduct has taken place, it should be acknowledged publicly. Justice has to be seen to be done. Sexual assault, of course, is another matter entirely – that should go straight to the police to deal with.

I’ve talked about protocols and procedures, but these can only ever apply a sticking-plaster solution to a problem which is extremely deeply rooted in the culture of many science departments and research teams across the world. These tend to be very hierarchical, with power and influence concentrated in the hands of relatively few, usually male, individuals. A complaint about harassment generally has to go up through the management structure and therefore risks being blocked at a number of stages for a number of reasons. This sort of structure reinforces the idea that students and postdocs are at the bottom of the heap and discourages them from even attempting to pursue a case against someone at the top.

The unhealthy power structures I’ve discussed will not be easy to dismantle entirely, but there are simple things that can be done to make a start. “Flatter”, more democratic, structures not only mitigate this problem but are also probably more efficient by, for example, eliminating the single-point failures that plague hierarchical organisational arrangements.

We are very far indeed from eliminating harassment or the conditions that allow it to continue but although cases like this are painful, I think they at least demonstrate that we are beginning to acknowledge that there’s a problem.

I think we’re now long past the point where acknowledgement is necessary. It’s now time to take action against the individuals and institutions responsible for perpetuating the problem.

Why you should proofread your emails before sending them..

Posted in Uncategorized on June 9, 2018 by telescoper

If you have any amusing email gaffes to report please do so through the comments box. I have a few.

My favourite was from a (female) astronomer who replied to decline an email invitation to give a seminar because she was “too busty”.

There was also a “here is the reviled version of our paper”.

I also liked the one that included the phrase “your model has many appalling features”..

BBC NOW: Tchaikovsky and Shostakovich at St David’s Hall

Posted in Biographical, Music with tags , , , , , on June 8, 2018 by telescoper

Last night I took my seat in St David’s Hall for a concert by the BBC National Orchestra of Wales under the direction of Principal Conductor Thomas Søndergård. It was an all-Russian menu, and very enjoyable it was.

The first course was the Violin Concerto by Pyotr Ilyich Tchaikovsky. It’s a familiar work but it was ravishingly played by Latvian soloist Baiba Skride, who seemed to revel in the virtuosic elements of this work, as well as bringing out the lyricism in the more romantic passages. The Orchestra were on top form too. I particularly enjoyed the way they dealt with the introduction of the famous `big tune’ in the first movement: brisker and with less of the tendency to wallow in it than you find in many performances.

Then, after the wine break, we had the main dish for the evening, the Symphony No. 5 by Dmitri Shostakovich. This is a very famous work and is perhaps the most accessible of all the Shostakovich symphonies. It was an immediate success with Soviet critics and public alike when it was first performed in 1937, and though it marked Shostakovich’s return to favour with the authorities after his denunciation by Stalin, this work has the composer’s very characteristic sense of things not being quite as they seem on the surface. Indeed, in this and many other of his compositions, he seems to manage to say one thing at the same time as saying the exact opposite of that thing; nowadays this might be called `constructive ambiguity’. This is especially in the finale, in which the sense of triumph is almost a parody of itself. Overall the Fifth Symphony is a sombre work, the dark undertone established right at the start with an imposing theme on the cellos and double basses, but it has passages of great beauty too, especially in the slow third movement. Like all great symphonies – and this is one of the greatest – it takes you on a journey full of of excitement and interest. The 45 minutes or so of this performance seemed to fly by, and its ending was greeted with rapturous applause and a standing ovation from many in the audience.

It’s interesting to consider that only 60 years had elapsed between the composition of these two pieces, but what different worlds they represent!

Anyway, the full strength National Orchestra of Wales, produced a gripping performance of this tremendous work with every section playing at the top of its form and the finale really brought the house down. But you don’t have to take my word for it – the whole concert will be broadcast on BBC Radio 3 next Tuesday, 12th June.

This concert is the last of the BBC National Orchestra of Wales season at St David’s Hall and indeed the last of at St David’s with Thomas Søndergård as Principal Conductor (though he will be conducting the Orchestra a couple of times at the Proms this summer). I wish him all the very best for his future musical adventures. It’s also the last concert by the BBC National Orchestra of Wales I’ll be attending before departing for Ireland. I don’t think I’ll get much chance to hear them after I’ve relocated, so let me take this opportunity to thank every single member of the Orchestra for the many performances I’ve enjoyed over the years, and to wish them well for the future.

History of astronomy – reading the classics

Posted in History, The Universe and Stuff on June 7, 2018 by telescoper

I’m sharing this excellent blog post here on this blog for the edification and benefit of anyone interested in the history of astronomy as it contains a really useful list of references and comments related thereto!

thonyc's avatarThe Renaissance Mathematicus

Most non-specialists get their knowledge of the history of astronomy from general surveys of the subject or from even more general surveys of the history of science. The information contained in these on Ptolemaeus, Copernicus and the other boys in the history of astronomy band is often from secondary if not tertiary or even quaternary sources and as a result also often inaccurate if not completely false. The solution to this problem is of course to read the originals but not all of us are blessed with the linguistic abilities necessary to tackle second century Greek or Early Modern Latin, to say nothing of Galileo’s seventeenth century Tuscan. However, the current scholar interested in the classical texts from the history of astronomy is blessed with modern, annotated English translations of these and in this post I want to briefly present these and some secondary literature to assist in understanding them.

Captain James Doohan

Posted in History, Television with tags , , , , , on June 6, 2018 by telescoper

The pictures above are photographs of a young Captain James Doohan of the Royal Canadian Artillery.

Doohan was in action on D-Day where he served with exceptional courage and distinction during the assault on Juno beach. He killed two enemy snipers and successfully led his men on foot through a minefield. Doohan was then hit six times by machine gun fire, 4 times in the leg, once in the finger, and once in the chest. The latter round would probably have killed him but for the cigarette case he had in his tunic pocket which deflected the bullet.

In case you haven’t yet realised, after the war was over, James Doohan became an actor, best known for the role of ‘Scotty’ in the TV series Star Trek…

Captain James Doohan was just one of around 160,000 officers and men who took part in the invasion of Normandy that began on 6th June 1944.

Another, not now famous, whose name along with many others, I came across this morning while waiting for my plane, was a George Jones of No 4 Commando who landed at Ouistreham (Sword beach) with the 1st Special Service Brigade around 7.30am on D-Day. Between the beach and Pegasus Bridge, four miles inland, his unit was constantly under fire and all but 80 of his 500 comrades were killed or wounded.

George Jones, James Doohan and countless other brave men like them were fighting to liberate a continent from Nazi tyranny. It is to our shame that so many today who owe their freedom to the sacrifices of an earlier generation are once again marching to the fascist drum.

Back to Cardiff again..

Posted in Cardiff, Maynooth with tags , on June 6, 2018 by telescoper

So here I am again, back in sunny Cardiff (if a bit later than planned). My flight from Dublin was supposed to depart at 8.35, but didn’t go until over an hour later. The delay was allegedly caused by a lightning strike last night that required the plane to be checked before take-off. Although they must have known about this mishap for some time, FlyBe didn’t bother to tell us anything about the reason for the delay or how long it would be. This was the scene at the (unstaffed) departure gate at about 9.15am. The lack of communication or any form of customer service compounds the irritation caused by such delays.

Anyway, once airborne, it was a pleasant flight. Here are two pictures just after taking off from Dublin Airport, with a view up to Malahide in the North.

And here are a few more flying over Wales about 10 minutes before landing.

We landed about 85 minutes late in Cardiff, but it’s lovely weather here so I’m not as grumpy as I might have been. Now, to work.

A Mini-Introduction To Information Theory

Posted in The Universe and Stuff with tags , , , on June 5, 2018 by telescoper

The last link to an arXiv paper I posted here seems to have proved rather popular so here’s another that I think is well worth reading, this time by Ed Witten:

This article consists of a very short introduction to classical and quantum information theory. Basic properties of the classical Shannon entropy and the quantum von Neumann entropy are described, along with related concepts such as classical and quantum relative entropy, conditional entropy, and mutual information. A few more detailed topics are considered in the quantum case.

It’s not really `very short’ as it is nearly 40 pages long, but it does tackle a very big topic so I won’t quibble about that. You can download a PDF of the full paper here.

Lá Saoire i mí Mheitheamh

Posted in Biographical, History, Maynooth, Uncategorized with tags , , , on June 4, 2018 by telescoper

So here I am, in Maynooth, on my birthday. I’ve made such an impression here in Ireland since I arrived that they’ve declared this day a national holiday so I’ve got the day off.

The June Bank Holiday (Lá Saoire i mí Mheitheamh) in Ireland is actually the equivalent of last week’s late May Bank Holiday in the UK, in that both have their origin in the old festival of Whitsuntide (or Pentecost) which falls on the 7th Sunday after Easter. Because the date of Easter moves around in the calendar so does Whit Sunday, but it is usually in late May or early June. When the authorities decided to fix a statutory holiday at this time of year, presumably to reduce administrative difficulties, the UK went for late May and Ireland for early June. Whit Sunday was actually on 20th May this year.

Incidentally, when I was a lad, ‘Whit Week’ was always referred to as ‘Race Week’. Geordie Ridley’s famous music hall song The Blaydon Races begins “I went to Blaydon Races, ’twas on the 9th of June, Eighteen Hundred and Sixty Two on a summer’s afternoon…”. Easter Sunday fell on 20th April in 1862, so Whit Sunday was on 8th June. After raucous scenes at the Blaydon Races, they were scrapped and replaced with a Temperance Festival on the Town Moor in Newcastle which evolved into one of the largest open-air funfairs in Europe, The Hoppings.

Anyway, with this birthday, I have now reached the minimum retirement age in the UK university pension scheme, so I could start drawing my pension when I leave Cardiff University next month. For a time I was planning to do that, but Ireland has given me a new lease of life, so to speak, so thoughts of retirement have receded.

Today also represents a short hiatus before our formal Exam Board meeting tomorrow, then I’ll be back in Cardiff for exam business there. And next week I’ll be in neither Cardiff nor Maynooth…

Ode to Tayto

Posted in Uncategorized with tags , , on June 3, 2018 by telescoper

One of the deep cultural differences I have discovered between Ireland and the United Kingdom lies in the arena of potato crisps.

Here the crisp of choice for the discerning consumer is the Tayto, a brand I have not seen elsewhere (though apparently it is also made under licence in Northern Ireland). So familiar is the name Tayto over here that people use it to refer to any kind of crisp, in much the same way that in the UK you might use ‘Hoover’ to refer to any kind of vacuum cleaner.

If you don’t believe that a humble potato crisp can be a cultural phenomenon then note that there is even a Tayto Park which is only 30 minutes from Dublin but which, regrettably, I have not yet visited.

Tayto’s crisps have been around since 1954 and the manufacturer is credited with inventing the method of production of flavoured potato crisps. Tayto has the right, therefore, to call itself the original potato crisp.

Naturally, while in Ireland I try to buy locally produced items whenever possible, so I have sampled Tayto crisps on a number of occasions. They come in a relatively narrow range of flavours, but the Cheese & Onion variety is definitely nicer than, e. g. Walkers.
