Hard BrExit Reality Bites UK Science

Posted in Politics, Science Politics with tags , , , , , , on January 17, 2017 by telescoper

Before lunch today I listened to the Prime Minister’s much-heralded speech (full text here) at Lancaster House giving a bit more detail about the UK government’s approach to forthcoming negotiations to leave the European Union. As I had expected the speech was mainly concerned with stating the obvious – especially about the UK leaving the so-called Single Market – though there was an interesting, if rather muddled, discussion of some kind of associate membership of the Customs Union.

As I said when I blogged about the EU Referendum result back in June last year

For example, there will be no access to the single market post-BrExit without free movement of people.

The EU has made it perfectly clear all along that it will not compromise on the “four freedoms” that represent the principles on which the Single Market (correct name; “Internal Market”) is based. The UK government has also made it clear that it is running scared of the anti-immigration lobby in the Conservative Party and UKIP, despite the mountain of evidence (e.g. here) that immigration actually benefits the UK economy rather than harming it. A so-called “hard BrExit” approach has therefore been inevitable from the outset.

In any case, it always seemed to me that leaving the EU (and therefore giving up democratic representation on the bodies that govern the single market) but remaining in the Single Market would be completely illogical to anyone motivated by the issue of “sovereignty” (whatever that means).  So I think it always was – and still is – a choice between a hard BrExit and no BrExit at all. There’s no question in my mind – and Theresa May’s speech has hardened my views considerably – that remaining in the EU is by far the best option for the UK. That outcome is looking unlikely now, but there is still a long way to go and many questions have still to be answered, including whether the Article 50 notification can be revoked and whether the devolved assemblies in Scotland and Northern Ireland have to give separate consent. Interestingly, the Conservative Party manifesto for the 2015 General Election included a commitment to work within the Single Market, so it would be within the constitutional limits on the House of Lords to vote down any attempt to leave it.

Overall, I felt the speech was worthwhile insofar as it gave a bit of clarity on some issues, but it was also full of contradictions on others. For example, early on the PM stated:

Parliamentary sovereignty is the basis of our constitution.

Correct, but in that case why did the UK government appeal the High Court’s decision that this was the case (i.e. that Parliamentary consent was needed to invoke Article 50)? Moreover, why if she thinks Parliament is so important did she not give today’s speech in the House of Commons?

This brings me to what the speech might imply for British science in a post-BrExit era. Here’s what I said in June 2016:

It’s all very uncertain, of course, but it seems to me that as things stand, any deal that involves free movement within Europe would be unacceptable to the powerful  UK anti-immigration lobby. This rules out a “Norway” type deal, among others, and almost certainly means there will be no access to any science EU funding schemes post 2020. Free movement is essential to the way most of these schemes operate anyway.

I’m by no means always right, but I think I was right about that. It is now clear that UK scientists will not be eligible for EU funding under the Horizon 2020 programme.  Switzerland (which is in the Single Market) wasn’t allowed to remain in Horizon 2020 without freedom of movement, and neither will the UK. If the PM does indeed trigger Article 50 by the end of March 2017 then we will leave the EU by April 2019. That means that existing EU projects and funding will probably be stopped at that point, although the UK government has pledged to provide short-term replacement funding for grants already awarded. From now on it seems likely that EU teams will seek to exclude UK scientists.

This exclusion is not an unexpected outcome, but still disappointing. The PM’s speech states:

One of our great strengths as a nation is the breadth and depth of our academic and scientific communities, backed up by some of the world’s best universities. And we have a proud history of leading and supporting cutting-edge research and innovation.

So we will also welcome agreement to continue to collaborate with our European partners on major science, research, and technology initiatives.

From space exploration to clean energy to medical technologies, Britain will remain at the forefront of collective endeavours to better understand, and make better, the world in which we live.

Warm words, but it’s hard to reconcile them with reality.  We used to be “leading” EU collaborative teams. In a few years we’ll  be left standing on the touchlines. The future looks very challenging for science, and especially for fundamental science, in the UK.

But the politics around EU science programmes pales into insignificance compared the toxic atmosphere of xenophobia that has engulfed much of the UK. The overt policy of the government to treat EU citizens in the UK as bargaining chips will cause untold stress, as will the Home Office’s heavy-handed approach to those who seek to confirm the permanent residence they will otherwise lose when the UK leaves the EU. Why should anyone – scientist or otherwise – stay in this country to be treated in such a way? 

All of this makes me think those scientists I know who have already left the UK for EU institutions probably made the right decision. The question is how many more will follow?

Cotton Tail

Posted in Jazz with tags , , , , on January 16, 2017 by telescoper

It’s been a very busy and rather trying day so I’m in need of a bit of a pick-me-up. This will do nicely! It’s the great Duke Ellington band of 1940 playing Cotton Tail. This tune – yet another constructed on the chord changes to George Gershwin’s I Got Rhythm – was written by Ben Webster and arranged by Duke Ellington for his orchestra in a characteristically imaginative and inventive way. Webster’s “heavy” tenor saxophone dominates the first half of the track, but the real star of the show (for me) is the superb brass section of the Ellington Orchestra whose tight discipline allows it to punch out a series of complicated riffs with a power and precision that would terrify most classical orchestras. And no wonder! The Ellington band of this era was jam-packed  with talent, including: Rex Stewart (cornet); Wallace Jones, Ray Nance, and Cootie Williams (trumpet); Juan Tizol,  Joe”Tricky Sam” Nanton, and Lawrence Brown (trombones). Listen particularly to the two sequences from 1.33-1.49 and 2.35-2.59, which are just brilliant! Enjoy!

P.S. The drummer is the great Sonny Greer.

Cardiff Brewery Tap wins Beard Friendly Pub of the Year title (UK)

CARDIFF BREWERY TAP WINS BEARD FRIENDLY PUB OF THE YEAR TITLE

crafty

The Beard Liberation Front, the informal network of beard wearers, has said that the contest for the Beard Friendly Pub of the Year has concluded with the Crafty Devil Beer Cellar in Cardiff bearding the Cloudwater brewery tap in Manchester for the UK (outside of London) title

The Cock Tavern in Hackney won the overall poll but the result of the on-line vote saw a major new development with Brewery Taps- where drinkers socialise at the breweries themselves- coming second and third in the overall national vote.

The winners in 2016 included the Jolly Butchers in Stoke Newington, the Cock Tavern in central Hackney and the Bag of Nails in Bristol

Paddy’s Market

Posted in Biographical on January 14, 2017 by telescoper

When I was a kid my Mum would use the expression “Paddy’s Market” quite often, to describe a messy, chaotic place e.g.

Tidy up your bedroom! It’s like Paddy’s Market!

Actually, that’s not so much an “e.g.” as an “invariably”.

Anyway, I always assumed that “Paddy’s Market” was a well-known term, but later began to think it wasn’t used very much at all in the Big Wide World.

The name “Paddy’s Market” clearly derives from the name of a place in Glasgow, which is perhaps testament to my family’s Scottish connections but it may be commonplace on Tyneside (where I was born) and even elsewhere. I just don’t know how widespread is its use.

Anyone out there in the blogosphere care to comment?

How Long Blues – Jimmy Yancey

Posted in Jazz with tags , on January 13, 2017 by telescoper

Over the past weeks I’ve been posting tracks by the legendary pianist Jimmy Yancey. They seem to have proved quite popular, so here’s another one. This differs from the others (which were in the boogie-woogie style) in being a slow blues rather than an up-tempo boogie-woogie romp. It’s quite an old song, dating back to 1928, of which many versions have been made over the years, but this is an atmospheric masterpiece that shows what a superb interpreter of the blues Jimmy Yancey was. That gently rocking left hand and the beautiful articulation of the right hand seem to underline the sense of loss conveyed in the lyrics to the song, which is about a man whose lover who has left him:

Heard the whistle blowin’, couldn’t see no train
Way down in my heart, I had an achin’ pain
How long, how long, baby how long

You won’t hear many better – or more haunting – performances the blues than this. And who cares if there’s a bit of surface noise on the record?

Why Universities should ignore League Tables

Posted in Bad Statistics, Education with tags , , , , , on January 12, 2017 by telescoper

Very busy day today but I couldn’t resist a quick post to draw attention to a new report by an independent think tank called the Higher Education Policy Institute  (PDF available here; high-level summary there). It says a lot of things that I’ve discussed on this blog already and I agree strongly with most of the conclusions. The report is focused on the international league tables, but much of what it says (in terms of methodological criticism) also applies to the national tables. Unfortunately, I doubt if this will make much difference to the behaviour of the bean-counters who have now taken control of higher education, for whom strategies intended to ‘game’ position in these, largely bogus, tables seem to be the main focus of their policy rather than the pursuit of teaching and scholarship, which is what should universities actually be for.

Here is the introduction to high-level summary:

Rankings of global universities, such as the THE World University Rankings, the QS World University Rankings and the Academic Ranking of World Universities claim to identify the ‘best’ universities in the world and then list them in rank order. They are enormously influential, as universities and even governments alter their policies to improve their position.

The new research shows the league tables are based almost exclusively on research-related criteria and the data they use are unreliable and sometimes worse. As a result, it is unwise and undesirable to give the league tables so much weight.

Later on we find some recommendations:

The report considers the inputs for the various international league tables and discusses their overall weaknesses before considering some improvements that could be made. These include:

  • ranking bodies should audit and validate data provided by universities;
  • league table criteria should move beyond research-related measures;
  • surveys of reputation should be dropped, given their methodological flaws;
  • league table results should be published in more complex ways than simple numerical rankings; and
  • universities and governments should not exaggerate the importance of rankings when determining priorities.

No doubt the purveyors of these ranking – I’ll refrain from calling them “rankers” – will mount a spirited defence of their business, but I agree with the view expressed in this report that as they stand these league tables are at best meaningless and at worst damaging.

Bayesian weak lensing tomography: Reconstructing the 3D large-scale distribution of matter with a lognormal prior [CEA]

Posted in Uncategorized on January 11, 2017 by telescoper

Bayesian and Lognormal! How could I resist a reblog of this arXiver post?

arxiver's avatararXiver

http://arxiv.org/abs/1701.01886

We present a Bayesian reconstruction algorithm that infers the three-dimensional large-scale matter distribution from the weak gravitational lensing effects measured in the image shapes of galaxies. The algorithm assumes that the prior probability distribution of the matter density is lognormal, in contrast to many existing methods that assume normal (Gaussian) distributed density fields. We compare the reconstruction results for both priors in a suite of increasingly realistic tests on mock data. We find that in cases of high noise levels (i.e. for low source galaxy densities and/or high shape measurement uncertainties), both normal and lognormal priors lead to reconstructions of comparable quality. In the low-noise regime, however, the lognormal model produces significantly better reconstructions than the normal model: The lognormal model 1) enforces non-negative densities, while negative densities are present when a normal prior is employed, 2) better traces the extremal values and the skewness of the true underlying…

Status of Dark Matter in the Universe [CEA]

Posted in The Universe and Stuff with tags , on January 11, 2017 by telescoper

Courtesy of arXiver, here’s a nice review article if you want to get up to date with the latest ideas and evidence about Dark Matter…

arxiver's avatararXiver

http://arxiv.org/abs/1701.01840

Over the past few decades, a consensus picture has emerged in which roughly a quarter of the universe consists of dark matter. I begin with a review of the observational evidence for the existence of dark matter: rotation curves of galaxies, gravitational lensing measurements, hot gas in clusters, galaxy formation, primordial nucleosynthesis and cosmic microwave background observations. Then I discuss a number of anomalous signals in a variety of data sets that may point to discovery, though all of them are controversial. The annual modulation in the DAMA detector and/or the gamma-ray excess seen in the Fermi Gamma Ray Space Telescope from the Galactic Center could be due to WIMPs; a 3.5 keV X-ray line from multiple sources could be due to sterile neutrinos; or the 511 keV line in INTEGRAL data could be due to MeV dark matter. All of these would require further confirmation in other experiments…
