Spring is like a perhaps hand

Spring is like a perhaps hand
(which comes carefully
out of Nowhere) arranging
a window,into which people look (while
people stare
arranging and changing placing
carefully there a strange
thing and a known thing here) and

changing everything carefully

spring is like a perhaps
Hand in a window
(carefully to
and from moving New and
Old things, while
people stare carefully
moving a perhaps
fraction of flower here placing
an inch of air there) and

without breaking anything.

by e e cummings (1894-1962).

The Royal Observatory Bomb and the Rise of Unreason

Posted in History, Literature, Politics, Science Politics with tags , , , , , , , , , , on February 16, 2014 by telescoper

I missed the anniversary by a day but I thought I’d pass on a fascinating but very sad little bit of history. One hundred and twenty years ago yesterday, on February 15th 1894, a 26-year old Frenchman by the name of Martial Bourdin blew himself up near the Royal Observatory in Greenwich. His death seems to have been an accident caused by the bomb he was carrying going off prematurely. It is not really known either whether the bomb was meant for the Royal Observatory or somewhere else. Anarchist attacks involving bombs were not uncommon in the 1890s and the range of targets was very wide.

Bourdin was found alive, though very seriously injured, by people who heard the blast. Though able to speak he did not offer any explanation for what had happened. He died about half an hour later.

This sad and perplexing story inspired Joseph Conrad‘s famous novel The Secret Agent. Conrad added an “Author’s Note” to the manuscript of his book:

The attempt to blow up the Greenwich Observatory: a blood-stained inanity of so fatuous a kind that is is impossible to fathom its origin by any reasonable or even unreasonable process of thought. For perverse unreason has its own logical processes. But that outrage could not be laid hold of mentally in any sort of way, so that one remained faced by the fact of a man blown to pieces for nothing even most remotely resembling an idea, anarchistic or other. As to the outer wall of the Observatory, it did not show as much as the faintest crack.

We’ll never know what Bourdin’s motivations were; perhaps he didn’t really know himself. He is usually described as an “anarchist” although that term describes such a wide spectrum of political beliefs that it doesn’t really explain Bourdin’s actions; not all anarchists embrace violence and aggression, for example, although some – such as the members of Class War – clearly do. At one end of the anarchist spectrum there are the violent thugs who are nothing more than the mirror image of fascism and at the other there are reasonable intelligent people who simply don’t believe in hierarchical structures.

Brighton has its share of anarchists and the thing that’s most noticeable about them to an outsider like me is their conformity; the dress code is apparently very strictly enforced. The obvious irony aside, this suggests to me that much of the attraction of being an anarchist is not really the existence of a compelling political philosophy, but simply to fulfill the need to belong to something.

The main thing that occurred to me yesterday while I was reading about the Greenwich Observatory bomb plot concerns the implications of the location. If the Royal Observatory was the intended target then why was it so? The simple answer is that a core belief for most varieties of anarchist is their opposition to “the State”. A powerful symbol of the British state in 1894 was the Royal Navy; it was Britain’s maritime traditions that led to the founding of the Royal Observatory in the first place and most of the work carried out there involved accurate positional measurements designed to help with navigation. Or maybe it was to do with the role of the Observatory in defining the time? Insofar as acts like this make any sense at all, these seem reasonable interpretations. 

I’m tempted to suggest that the adoption of Greenwich as the Prime Meridian in 1884 may have given a young Frenchman additional grounds for resentment..

A different answer from the suggestion that it was an anti-establishment gesture stems from  the conflict between anarchism and the nature of scientific knowledge. Anarchists usually express their beliefs in terms of the desire to make society more “equal” and “democratic”, so that decisions should be made collectively for the common good. I’m happy with that line of argument, and agree that we should all enjoy equal rights versus the government and other institutions, and in relation to one another. However, having equal rights does not mean having equal knowledge and it doesn’t mean that any person’s opinion about anything is as good as anyone else’s. What I mean is that there are scientific experts, and the knowledge they possess has demonstrable value.

The approach of some to this challenge is simply to deny the value of scientific knowledge, and assert instead that it’s just a social construct like anything else. I am aware of a number of so-called social scientists at the University of Sussex and elsewhere who hold this view; my usual response is to ask them whether they regard witchcraft or crystal healing as equal to orthodox medicine.

CLARIFICATION: Please note I do not mean to imply that all social scientists hold the opinions described above. I’m fully aware that they are fringe views. The phrase “so-called social scientists” does not refer to all social scientists, just the fringe in much the same way I’d use “so-called geographers” to describe the Flat Earth Society.

I’m not trying to suggest that members of the Department of Sociology are plotting to blow up the Astronomy Centre! What I do think that while we should always strive to be as democratic as possible there are always limits, not just because of what is practically possible but also what is socially desirable. Any organization in which everyone votes about every decision that has to be made would struggle to function at all. We have to find ways of working that make best use of the different skills and knowledge we all possess.

A constructive approach is to argue that if we are to build  a more democratic society it is first necessary to greatly increase the level of scientific literacy in the population, so that more people can make informed decisions about the big issues facing the future, such as how we fulfill our energy requirements for the next 30 years and how we cope with global warming. That will not be an easy thing to do given the dearth of scientists in Parliament and in the media, but that’s not an argument for not trying.

Symptomatic of the widespread rejection of science among the politically disaffected is the lamentable state of Green politics in the United Kingdom. In my opinion there is huge potential for a scientifically-informed political movement focussed on environmental issues. Unfortunately the current Green Party is anti-science to the core, which would doom it to perpetual marginalization even without the loss of credibility stemming from the childish antics of the only Green MP, Caroline Lucas. I know that many will argue with me about whether the Green Party should be included in “The Left”, but since both Labour and Conservative parties now belong to the Centre-Right it seems a sensible classification to me.

It hasn’t always been like this. As Alice Rose Bell pointed out in a Guardian piece some time ago, there have been examples of constructive engagement between science and left-wing politics. This seems to me to have largely evaporated. I don’t think that’s so much because scientists have rejected the left. It’s more that the left has rejected science.

Brighton after another storm…

Posted in Biographical, Brighton with tags , , , on February 15, 2014 by telescoper

I got back from London a bit later than expected yesterday. I left the Athenaeum in good time to get the 10.06 from London Victoria back to Brighton. It was a bit breezy but not raining so I walked to the station, past Buckingham Palace. When I got there the 10.06 was marked as “delayed” on the screen. It stayed that way until about 10.15 at which point it became “cancelled”. The next train was the 10.36 which until then was apparently “on time” but in no time that was “cancelled” too. Faced with the prospect of waiting until 11.06 for the next chance of seeing a train cancelled, I got on a slow train to Bognor Regis via Hove; the connection to Brighton from there was late and I arrived about a quarter past midnight.

The weather didn’t seem particularly bad and there wasn’t a word of explanation for the cancellations. There was no sign of flooding en route and although it was a bit windy there was nothing extreme. Not impressed with Southern Rail I can tell you…

 

UPDATE: it appears that the problem was caused by flooding very close to Brighton, in fact at Preston Park. Ground water levels were so high that they flooded the signals equipment, a story repeated elsewhere on the network. Not that they bothered to tell any passengers this.

Something more like a storm hit Brighton in the early hours of the morning, and it did cause some damage along the seafront. This afternoon I took a stroll along and took a few snaps. The poor old West Pier, which has been left to rot since it was closed in the 1970s, is now on its last legs. Part of it collapsed a few weeks ago in another storm, and it can’t be long before the entire Pavilion section collapses into the sea:

I wasn’t on campus yesterday as I was in London, but it seems there has been a bit of damage here too. This tree must have just fallen:

It’s been a rough winter so far – not cold but lots of gales and rain. Still, at least there are signs that spring is not too far off: the crocuses have started to appear…

Coming out as a scientist

Posted in Education, LGBTQ+, The Universe and Stuff with tags , on February 14, 2014 by telescoper

So here I am sitting in the library at Burlington House, the Royal Astronomical Society Council meeting I was attending having just finished slightly ahead of schedule.

I only have time for a brief post, so I’ll take the opportunity to direct your attention to an interesting piece in the Grauniad by Tom Welton. Tom is Professor of Sustainable Chemistry at Imperial College. He was also a contemporary of mine in old Sussex days. He was doing a PhD in Chemistry in MOLS while I was doing mine in Astrophysics in MAPS. Come to think of it we both did DPhils actually.

Anyway, Tom’s piece is related to something I blogged about a while ago (being a gay scientist) but he turns it the other way round and writes about how the difficulties of coming out as a scientist to your gay friends..

The most beautiful equation?

Posted in The Universe and Stuff with tags , , , , on February 13, 2014 by telescoper

There’s an interesting article on the BBC website today that discusses the way mathematicians’ brains appear to perceive “beauty”. A (slightly) more technical version of the story can be found here. According to functional magnetic resonance imaging studies, it seems that beautiful equations excite the same sort of brain activity as beautiful music or art.

The question of why we think equations are beautiful is one that has come up a number of times on this blog. I suspect the answer is a slightly different one for theoretical physicists compared with pure mathematicians. Anyway, I thought it might be fun to invite people offer suggestions through the comments box as to the most beautiful equation along with a brief description of why.

I should set the ball rolling myself, and I will do so with this, the Dirac Equation:

dirac_equation

This equation is certainly the most beautiful thing I’ve ever come across in theoretical physics, though I don’t find it easy to articulate precisely why. I think it’s partly because it is such a wonderfully compact fusion of two historic achievements in physics – special relativity and quantum mechanics – but also partly because of the great leaps of the imagination that were needed along the journey to derive it and my consequent admiration for the intellectual struggle involved. I feel it is therefore as much an emotional response to the achievement of another human being – such as one feels when hearing great music or looking at great art – as it is a rational response to the mathematical structure involved. But it’s not just that, of course. The Dirac Equation paved the way to many further developments in particle physics. It seems to encapsulate so much about the behaviour of elementary particles in so few symbols. Some of its beauty also derives from its compactness.

Anyway, feel free to suggest formulae or equations through the comments box, preferably with a brief explanation of why you think they’re so beautiful.

The Floods

Posted in Poetry with tags , on February 12, 2014 by telescoper

royalflood

The rain it rains without a stay
In the hills above us, in the hills;
And presently the floods break way
Whose strength is in the hills.
The trees they suck from every cloud,
The valley brooks they roar aloud—
Bank-high for the lowlands, lowlands,
Lowlands under the hills!

The first wood down is sere and small,
From the hills—the brishings off the hills;
And then come by the bats and all
We cut last year in the hills;
And then the roots we tried to cleave
But found too tough and had to leave—
Polting through the lowlands, lowlands,
Lowlands under the hills!

The eye shall look, the ear shall hark
To the hills, the doings in the hills,
And rivers mating in the dark
With tokens from the hills.
Now what is weak will surely go,
And what is strong must prove it so—
Stand fast in the lowlands, lowlands,
Lowlands under the hills!

The floods they shall not be afraid—
Nor the hills above ’em, nor the hills—
Of any fence which man has made
Betwixt him and the hills.
The waters shall not reckon twice
For any work of man’s device,
But bid it down to the lowlands, lowlands,
Lowlands under the hills!

The floods shall sweep corruption clean—
By the hills, the blessing of the hills—
That more the meadows may be green
New-mended from the hills.
The crops and cattle shall increase,
Nor little children shall not cease.
Go—plough the lowlands, lowlands,
Lowlands under the hills!

by Rudyard Kipling 19865-1936).

 

 

More Cuts to University Funding

Posted in Education, Politics, Science Politics with tags , , , , , , on February 11, 2014 by telescoper

Grim news arrived yesterday with the announcement by the Department of Business, Innovation and Skills of further deep cuts in funding for Higher Education in England. This announcement has been delayed due to internal wrangling over the allocation of funds but in the end the grant letter to HEFCE makes little attempt to sugar the pill:

The settlement will mean reductions in HEFCE funding for higher education institutions in 2014-15 and again in 2015-16 beyond those accounted for by the switch to publicly funded tuition fees. The Government has asked HEFCE to deliver the reductions in ways which protect as far as possible high-cost subjects (including STEM), widening participation (which is funded via the HEFCE Student Opportunity allocation), and small and specialist institutions.

The science budget is, of course, “ring-fenced” which means that recurrent funding for that is maintained at £1,573 million, the same cash levels as 2013-14. This has, for example, translated into the expected flat cash settlement for the Science & Technology Facilities Council (STFC), although there has been some rejigging of the way this money is allocated within STFC, and an apparent increase in funds available for international subscriptions. At least this should unblock the numerous programmes in STFC and elsewhere in the Research Councils that have been on hold pending the final budget allocations.

That said, the overall picture looks very bleak for Higher Education. The really important figure for HEFCE is buried in Annex 2 of the latest grant letter, which reveals that, including the ring-fenced funds, HEFCE will have just £4,091 million to allocate in 2014/15. The corresponding figure for the current year, 2013/14, was £5,014 million. That’s a cut in cash terms of an eye-watering 18.4%.

The scale of the cuts makes it even more likely that if they continue there will be very little money available for HEFCE to allocate as a result of the 2014 Research Excellence Framework, in which case the vast expenditure across the sector preparing for that exercise may will have been wasted too.

For the time being, however, it seems that research has been spared the axe. The bulk of the cuts will therefore fall on teaching grants. HEFCE has been instructed to try to protect STEM subjects as it cuts expenditure on teaching, but will it be able to? The extra funds that have previously supplemented tuition fees have been steadily whittled away anyway, so expensive subjects like Physics only get about £1000 per year more than Arts subjects. There is already a strong incentive in the current funding model for universities to expand cheap subjects. That pressure will only increase with this new settlement.

The last paragraph of the grant letter says:

We recognise that our universities are one of our most valuable national assets. Higher education transforms people’s lives through excellent teaching and transforms society through research and the application of knowledge. The Government’s reforms have laid the foundations for a more securely funded, stronger, more confident and more responsive higher education sector. We will continue to work with the Council and the sector to communicate the enduring value of higher education to potential students and the wider world.

I’m sure readers of this blog will forgive me if I suggest that these words are rendered meaningless by the scale of the cuts announced in the grant letter. If the government really regarded our universities as “valuable national assets” it would be increasing investment in them, not cutting it. What worries me most is that these cuts will never be reversed, whatever the complexion of the next government as there seems to be more enthusiasm across the political spectrum for continued cuts than for investment in the future education of our young people. I’m increasingly ashamed of the legacy being left by my own generation.
