Too Brave To Dream

One day last week I found this wonderful item had been delivered to my house. Is a new book called Too Brave To Dream which contains about three dozen previously unpublished poems by R.S. Thomas, who died in 2000. After his death, two seminal studies of modern art were found on his bookshelves – Herbert Read’s Art Now (1933/1948) and Surrealism (1936), edited by Read and containing essays by key figures in the Surrealist movement. Poems handwritten by Thomas were later discovered between the pages of the two books. These poems written in response to a selection of the many reproductions of modern art in the Read volumes, including works by Henry Moore, Edvard Munch, George Grosz, Salvador Dalí, René Magritte and Graham Sutherland – many of whom were Thomas’s near contemporaries. Written between 1987 and 1993, these poems are published in Too Brave To Dream for the first time – alongside reproductions of the works of modern art that inspired them. They poems are instantly recognizable as works of R.S. Thomas. According to the publishers blurb:

Thomas’s readings of these often unsettling images demonstrate a willingness to confront, unencumbered by illusions, a world in which old certainties have been undermined. Personal identity has become a source of anguish, and relations between the sexes a source of disquiet and suspicion. Thomas’s vivid engagements with the works of art produce a series of dramatic encounters haunted by the recurring presence of conflict and by the struggle of the artist who, in a frequently menacing world, is ‘too brave to dream’.

The poems vary considerably in style and mood. Some are wry and playful – although Thomas isn’t perhaps best known for his sense of humour, he certainly wasn’t averse to playing with words and you can find puns throughout his work including in these new poems. Others are bleaker in tone, reflecting the disturbing nature the artworks to which they respond.

Incidentally, these poems were all written after Thomas had, after forty years of service, retired from his post as an Anglican priest. He seems to have experienced something of a crisis after his retirement, perhaps because of the lack of daily routine and regular duties require of him by the Church. He wrote to a friend in 1978, just before his retirement

I am retiring at Easter. I shall be 65. I could stay till 70, but I am glad to go from a Church I no longer believe in, sycophantic to the queen, iconoclastic with language, changing for the sake of change and regardless of beauty.

The form of his religious faith was never straightforward to R.S. Thomas but it did continue to dominate his poetry. He may have given up on the Anglican Church but that does not imply he had given up on religion altogether.

The poem that gives this book is title is a response to one of Henry Moore’s Shelter Sketches. During the ‘Blitz’ the London Underground served as a shelter for Londoners – who not only used the platforms as refuges, but also slept there. Moore produced a group of drawings based on his observations of people in the shelters. They’re are revelation if you think of Moore only as a sculptor but in any case they are very powerful images. I can’t reproduce the particular example that inspired the poem in question here for copyright reasons, but it is dated 1941 and is a sombre image of a figure in what appears to be a restless sleep, presumably during an air raid, with one hand rolled into a fist. Here is Thomas’s poem:

Hand clenched
on the dark dream
where the sleeper wanders
far from the crackling
meadows and the sharp flowers
with their smell
of combustion. Alas
that waking to safety
should be waking also
to survivors poking
among the remains of others
who were too brave to dream.

 

I’ve enjoyed dipping into this book enormously not only for the “new”poems by one of my favourite poets but also because of the interesting cross-section of influential works of art that it includes, including a number of artists who were completely new to me. If you’re interested in poetry or art you’ll find this book fascinating!

The Heavens Themselves…

Posted in Uncategorized on November 6, 2016 by telescoper

The heavens themselves, the planets and this centre 
Observe degree, priority and place, 
Insisture, course, proportion, season, form, 
Office and custom, in all line of order; 
And therefore is the glorious planet Sol 
In noble eminence enthroned and sphered 
Amidst the other; whose medicinable eye 
Corrects the ill aspects of planets evil, 
And posts, like the commandment of a king, 
Sans cheque to good and bad: but when the planets 
In evil mixture to disorder wander, 
What plagues and what portents! what mutiny! 
What raging of the sea! shaking of earth! 
Commotion in the winds! frights, changes, horrors, 
Divert and crack, rend and deracinate 
The unity and married calm of states 
Quite from their fixure! O, when degree is shaked, 
Which is the ladder to all high designs, 
Then enterprise is sick! How could communities, 
Degrees in schools and brotherhoods in cities, 
Peaceful commerce from dividable shores, 
The primogenitive and due of birth, 
Prerogative of age, crowns, sceptres, laurels, 
But by degree, stand in authentic place?

CAMPAIGNERS WARN ON GUY FAWKES BONFIRE NIGHT POGONOPHOBIA

The Beard Liberation Front, the informal network of beard wearers, has warned of Guy Fawkes pogonophobia as bonfires around the country burn effigies of a hirsute man over the weekend.

Pogonophobia is the ancient Greek for an irrational fear or hatred of facial hair, known as beardism in modern English.

The BLF says that November 5th is the traditional highlight of the pogonophobes year as they burn an effigy of what they assume to be a dangerous radical figure with a beard, although few will openly discuss their often deep-seated concerns about beard wearers

BLF Organiser Keith Flett said the irony is that Guy Fawkes was a deeply reactionary character who, had he lived now, would almost certainly not have had a beard under any circumstances

Judgment Day on Article 50

Posted in Politics with tags , , on November 3, 2016 by telescoper

I couldn’t resist a quick comment on today’s ruling by the High Court that the Prime Minister cannot trigger Article 50 of the Lisbon Treaty (and thus begin the process of taking the United Kingdom out of the European Union) without the approval of Parliament. The case was brought by Gina Miller and Deir Tozetti Dos Santos (the claimants) and has important constitutional implications because it limits the use of the Royal Prerogative.

I’m not by any means a legal expert but reading the full judgment it strikes me that this unanimous decision represents a comprehensive defeat for the Government’s lawyers. The crucial paragraphs of the judgment are 92-94 if you wish to refer to them in the full judgment. Interestingly, the ruling  does not really rest on the claimants’ case at all but instead is based on a complete rejection of the main point of the Government’s submission. It looks like the Government’s lawyers bungled it pretty badly. Although the Government has indicated that it will appeal the result, it’s not obvious what the grounds for such an appeal might be. The appeal will be heard some time in December.

I’ve never made any secret of the fact that I am in favour of the United Kingdom remaining inside the European Union. Events since the referendum – especially the collapse of the pound – have strengthened that opinion, in fact.

I am baffled by the extreme reaction of many “Leave” voters to this judgment, especially those who voted that way in order to “restore Parliamentary sovereignty”. Some such individuals are claiming that this ruling is somehow anti-democratic. I don’t think that view is at all rational. If you voted Leave in order to get your sovereignty back then you should be very happy with this decision. In fact whichever side of the referendum debate you were on you should welcome this decision.

We live in a parliamentary democracy. That means that sovereignty rests in Parliament, not in the Prime Minister. This ruling merely asserts that fact. It does not overturn the referendum result  nor does it prevent Article 50 being triggered. It does assert that the Prime Minister’s chosen way to approach BrExit is unlawful. Democracy is nothing without the rule of law.

Incidentally, the judgment also contains the following statement which I think is worth quoting here:

The 2015 Referendum Act was passed against a background including a very clear briefing paper to Parliamentarians explaining that the referendum would have advisory effect only. Moreover, Parliament must have appreciated that the referendum was intended to be only advisory as the result of a vote in the referendum in favour of leaving the European Union would inevitably leave for future decision many important questions relating to the legal implementation of withdrawal from the European Union.

In other words the referendum in itself has no constitutional force and was specifically intended not to.

The government plans to appeal the Article 50 decision to the Supreme Court, at which point it may or may not be overturned. If the appeal fails, then there is one higher authority: the European Court of Justice. It would be a delicious irony if the UK government were forced to appeal there in order to proceed!

Supposing, though, that all appeals are exhausted and the Government is forced to debate Article 50 in Parliament. What would happen next?

Although a majority of MPs in the House of Commons were in favour of remaining in the European Union, circumstances have changed since the referendum and many would be reluctant to vote against the outcome. However, I can imagine a situation in which Parliament refuses to give approval to an Article 50 until it has sufficient knowledge of the Government’s negotiating position to be assured that the Government is not planning something reckless that would endanger the UK economically and/or politically. It is my personal belief that “something reckless” is precisely what the Government is planning, and that is why they were so keen not to have a vote in Parliament.

There was only one question on the ballot paper for the EU referendum – whether the United Kingdom should remain in the European Union or leave it. But what, if any, of the rights and benefits that currently accrue as a consequence of our membership of the EU can the UK keep if and when it leaves?  Who decides what rights can be removed from UK citizens?

There has been a lot of talk about “Hard BrExit” versus “Soft BrExit”. My personal view is that “Soft BrExit” (by which we would end up in a situation something like Norway) – which a sizable number of Leave voters envisaged when they voted – is not on the agenda at all. I think the Government is headed for a “Hard BrExit”, i.e. no membership of the internal market, no freedom of movement, no free movement of people, etc. That’s partly because of the ideological beliefs of the Tory cabinet and partly because that’s what the process pretty much guarantees. Article 50 is just about the UK leaving the European Union. That process has to be completed before any trade deals with the EU or other countries can be negotiated; such deals could take years to complete and in the meantime our economy will suffer. In the interim, we’ll be out with whatever the EU decides to allow us. I don’t think that will be very much at all.

I think that the Government knows that this outcome is not what a majority voted for, that it will have serious  economic consequences, and will produce a considerable political backlash. That is why the Government want to charge ahead as quickly as possible (in secret) so that nobody can stop them until it’s too late. In other words, they’re planning to use the referendum result as a pretext to further their own agenda. In order to this to work they have to avoid Parliamentary scrutiny. The High Court ruling – if it stands – effectively rules out this strategy. It is a victory for democracy.

 

 

 

 

 

 

Three Cheers for Three Chairs!

Posted in Uncategorized with tags , , , on November 2, 2016 by telescoper

Just a quick post to say public congratulations to three of my former colleagues in the Department of Physics and Astronomy at the University of Sussex.

My spies tell me that the following have recently been promoted to Professorial positions:

  • Kathy Romer (now Professor of Astrophysics) – Kathy is principal investigator of the XMM Cluster Survey collaboration and is coordinating cluster research for the Dark Energy Survey project.
  • Antony Lewis (now Professor of Cosmology) – Antony works on theoretical models of the early universe, as well as comparing observations with cosmological models, and is part of the core team analysing data from the Planck satellite.
  • Jacob Dunningham (now Professor of Physics)  – Jacob is Head of the Atomic Molecular & Optical (AMO) Physics group at Sussex  and works on quantum mechanical entanglement spans the fields of quantum information, quantum optics, Bose-Einstein condensation, and metrology.

As former  Head of School  I knew these were in the system but I left before the somewhat laborious promotions process was completed, so it’s very nice to receive confirmation that they all went through.

P.S. Extra-special congratulations to Kathy, because she was born on Tyneside (i.e. not in the Midlands).

 

Why I’m wearing a poppy again

Posted in Biographical, History with tags , , on November 2, 2016 by telescoper

Once again we’re coming up to Remembrance Sunday, an occasion to remember those who have given their lives in conflicts past and present. This is always held on the second Sunday in November in the United Kingdom, which means that this year it is on 13th November, so that it is close to the date of anniversary of the armistice that formally ended the First World War, which happened on 11th November 1918. Another way to commemorate this  is the observance of two minutes’ silence at 11am on 11th November itself. I plan to do that, next Friday  (which is the 11th November). I’ve kept my calendar free at 11 am precisely for that purpose.

Then there  is the wearing of a poppy. The poppy appeal raises money for veterans and their families, but the wearing of these little red paper flowers is something that not everyone feels comfortable with. Some people think that to wear a poppy is to celebrate militarism or even Britain’s imperialist past. I don’t see it that way at all. In fact, if someone asked me to wear a badge to support Britain’s participation in the invasion of Iraq, I’d certainly refuse.

I wrote about my reaction to the horror and futility of war some time ago, so I’ll try not to repeat myself except to say that, to me, the poppy is not about celebrating war or military prowess or imperialism, it’s simply about remembering those who died. In fact, one of the main reasons the paraphernalia of  Remembrance Day observances (the Poppy, the Cenotaph, the Tomb of the Unknown Soldier, etc) were set up in the first place was to remind not just people but also governments of the devastation caused by World War One. That’s why the Remembrance Day ceremonial laying of wreaths takes place in Whitehall, right at the heart of government. The ritual  was specifically intended to be a warning to the politicians who had brought the conflict about not to allow it to happen again.

As a young lefty student I grappled with the implications of the poppy appeal. The Peace Pledge Union produces white poppies, as an overtly anti-war symbol of remembrance. For a time I wore a white poppy but, although I am against war, I don’t think a policy of non-violence would have helped much against Hitler’s Nazi regime and therefore can’t really call myself an out-and-out  pacifist. One year I wore both white and red poppies, but since then I’ve decided to stick with a red one.

Of course many in the Establishment would like the poppy to turn into a symbol of obedience, a kind of alternative national flag. Some people choose not to wear it precisely because it has that implication. The sight of some hypocritical warmongers wearing the poppy at the Cenotaph on these occasions sickens me, but their betrayal does not make me want to stop wearing it myself. Neither does the fact that so many seem to be so contemptuous of the great strides that have been made over the past decades to try to construct a Europe defined by peaceful cooperation rather than by narrow-minded nationalism and conflict. The parallels between Britain in 2016 and Germany in 1933 seem to me to be frighteningly real,  and I fear very much for the future if we carry on in the direction we seem to be taking. All I can say is that I’m glad I’m not young.

People have  a wide range of views about the poppy and its meaning. There is no “right” answer – every person’s attitude is shaped by a number of factors, not least by whether or not they have lost a loved one in any form of armed conflict.  Some of us wear wear a poppy, some don’t. It’s a matter of choice. The fact that we have a choice is important in itself. I would probably refuse to wear a poppy myself if someone tried to make it compulsory.

Some poppy sellers use the slogan  Wear Your Poppy With Pride, but the original meaning  is much better expressed by the original, Lest We Forget. I’m not sure I wear mine with pride at all, in fact. What I feel is really more like shame, at the wastefulness and stupidity of armed conflict. I count myself incredibly lucky that I have never had to live through anything like that, not only because I’ve had a relatively peaceful and comfortable life, but also because I have never been tested in the way previous generations were. I wear the poppy to acknowledge their bravery and to recognize my own good fortune.  When I stand for the two minutes silence I remember those all who fell fighting on all sides of all wars, and  fallen civilians too.

When the newsreader Jon Snow decided not to wear a poppy on TV, there were angry complaints. I’m sure he didn’t mean disrespect to the cause but disliked the pressure being put on him to conform. I can see his point. It has to be voluntary if it is to mean anything at all.  But in the end I agree with Euan Ferguson’s piece in the Observer a few years ago:

I don’t like pressure being put on people to conform. Orthodoxy and fear are always to be regretted and today’s society is over-condemnatory, swift to its manufactured outrage. But this change seems to have come from below, not been ordered by bullies: the daily reports of life and death in the forces, of the danger other 20-year-olds daily find themselves facing. And is the symbolism of the poppy being degraded as it is customised? No. You can’t do much to the fabulous simplicity of this symbol. And the poppy doesn’t preach: it’s not about “right” or “wrong” wars, but about brave dead soldiers. And the message was, never, Remember in the way we tell you to remember. It is, simply, Lest We Forget.

So, yes. I am wearing a poppy again this year. You can decide to wear one if you wish. You can also decide not to.  It’s entirely up to you.  That’s the whole point really. It’s called Freedom.

Lest we forget.

Quantitative Evaluation of Gender Bias in Astronomical Publications from Citation Counts [IMA]

Posted in Uncategorized on November 1, 2016 by telescoper

Here’s an interesting paper from yesterday’s arXiv, looking at gender biases in various forms of bibliometric measures in the astronomical literature.

The key result is in Figure 6, if you haven’t got time to read the whole thing…

arxiver's avatararXiver

http://arxiv.org/abs/1610.08984

We analyze the role of first (leading) author gender on the number of citations that a paper receives, on the publishing frequency and on the self-citing tendency. We consider a complete sample of over 200,000 publications from 1950 to 2015 from five major astronomy journals. We determine the gender of the first author for over 70% of all publications. The fraction of papers which have a female first author has increased from less than 5% in the 1960s to about 25% today. We find that the increase of the fraction of papers authored by females is slowest in the most prestigious journals such as Science and Nature. Furthermore, female authors write 19$pm$7% fewer papers in seven years following their first paper than their male colleagues. At all times papers with male first authors receive more citations than papers with female first authors. This difference has been decreasing with time…

Hallowe’en Again…

Posted in Biographical, Music with tags , , , on October 31, 2016 by telescoper

It’s Hallowe’en again, and although I feel I should concoct something appropriate, I really don’t have time. I’ve decided therefore to recycle a couple of items I’ve previously posted on this lamentable occasion.

We never had Halloween when I was a kid. I mean it existed. People mentioned it. There were programmes on the telly. But we never celebrated it. At least not in my house, when I was a kid. It just wasn’t thought of as a big occasion. Or, worse, it was “American” (meaning that it was tacky, synthetic and commercialized).

So there were no Halloween parties, no costumes, no horror masks, no pumpkins and definitely no trick-or-treat when I was a lad.

Having never done trick-or-treat myself as a child, I never really had any clue what it was about until relatively recently. I’d always assumed “Trick or Treat?” was a rhetorical question or merely a greeting like “How do you do?”.

In fact my first direct experience of this peculiar custom  didn’t happen until I was in my mid-thirties and had moved to a suburban house in Beeston, just outside Nottingham. I was sitting at home one October 31st, watching the TV and – probably, though I can’t remember for sure – drinking a glass of wine, when the front door bell rang. I didn’t really want to, but I got up and answered it.

When I opened the door, I saw in front of me two small girls in witches’ costumes. Behind them, near my front gate, was an adult guardian, presumably a parent, keeping a watchful eye on them.

“Trick or Treat?” the two girls shouted. Trying my best to get into the spirit but not knowing what I was actually supposed to do, I answered “Great! I’d like a treat please”.

They stared at me as if I was mad, turned round and retreated towards their minder who was clearly making a mental note to avoid this house in future. Off they went and I, embarrassed at being exposed as a social inadequate, retired to my house in shame.

Ever since then I’ve tried to ensure that I never again have to endure such Halloween horrors. Every October 31st, when nightfall comes, I switch off the TV, radio and lights and sit soundlessly in the dark so the trick-or-treaters think there’s nobody home.

That way I can be sure I won’t be made to feel uncomfortable.

Anyway, despite my own  reservations about Hallowe’en, I’ve decided to resurrect the following little video which seems to be appropriate for the occasion. It’s made of bits of old horror B-movies but the music – by Bobby “Boris” Pickett and the Crypt-kickers is actually the second single I ever bought, way back in 1973…

A Cosmic Microwave Background Dipole Puzzle

Posted in Cute Problems, The Universe and Stuff with tags , , , , , on October 31, 2016 by telescoper

The following is tangentially related to a discussion I had during a PhD examination last week, and I thought it might be worth sharing here to stimulate some thought among people interested in cosmology.

First here’s a picture of the temperature fluctuations in the cosmic microwave background from Planck (just because it’s so pretty).

planck_cmb

The analysis of these fluctuations yields a huge amount of information about the universe, including its matter content and spatial geometry as well as the form of primordial fluctuations that gave rise to galaxies and large-scale structure. The variations in temperature that you see in this image are small – about one-part in a hundred thousand – and they show that the universe appears to be close to isotropic (at least around us).

I’ll blog later on (assuming I find time) on the latest constraints on this subject, but for the moment I’ll just point out something that has to be removed from the above map to make it look isotropic, and that is the Cosmic Microwave Background Dipole. Here is a picture (which I got from here):

dipole_map

This signal – called a dipole because it corresponds to a simple 180 degree variation across the sky – is about a hundred times larger than the “intrinsic” fluctuations which occur on smaller angular scales and are seen in the first map. According to the standard cosmological framework this dipole is caused by our peculiar motion through the frame in which microwave background photons are distributed homogeneously and isotropically. Had we no peculiar motion then we would be “at rest” with respect to this CMB reference frame so there would be no such dipole. In the standard cosmological framework this “peculiar motion” of ours is generated by the gravitational effect of local structures and is thus a manifestation of the fact that our universe is not homogeneous on small scales; by “small” I mean on the scales of a hundred Megaparsecs or so. Anyway, if you’re interested in goings-on in the very early universe or its properties on extremely large scales the dipole is thus of no interest and, being so large, it is quite easy to subtract. That’s why it isn’t there in maps such as the Planck map shown above. If it had been left in it would swamp the other variations.

Anyway, the interpretation of the CMB dipole in terms of our peculiar motion through the CMB frame leads to a simple connection between the pattern shown in the second figure and the velocity of the observational frame: it’s a Doppler Effect. We are moving towards the upper right of the figure (in which direction photons are blueshifted, so the CMB looks a bit hotter in that direction) and away from the bottom left (whence the CMB photons are redshifted so the CMB appears a bit cooler). The amplitude of the dipole implies that the Solar System is moving with a velocity of around 370 km/s with respect to the CMB frame.

Now 370 km/s is quite fast, but it’s much smaller than the speed of light – it’s only about 0.12%, in fact – which means that one can treat this is basically a non-relativistic Doppler Effect. That means that it’s all quite straightforward to understand with elementary physics. In the limit that v/c<<1 the Doppler Effect only produces a dipole pattern of the type we see in the Figure above, and the amplitude of the dipole is ΔT/T~v/c because all terms of higher order in v/c are negligibly smallFurthermore in this case the dipole is simply superimposed on the primordial fluctuations but otherwise does not affect them.

My question to the reader, i.e. you,  is the following. Suppose we weren’t travelling at a sedate 370 km/s through the CMB frame but instead enter the world of science fiction and take a trip on a spacecraft that can travel close to the speed of light. What would this do to the CMB? Would we still just see a dipole, or would we see additional (relativistic) effects? If there are other effects, what would they do to the pattern of “intrinsic” fluctuations?
