The Next Decade of Astronomy?

Posted in Science Politics, The Universe and Stuff with tags , , , , , , , on August 14, 2010 by telescoper

I feel obliged to pass on the news that the results of the Decadal Review of US Astronomy were announced yesterday. There has already been a considerable amount of reaction to what the Review Panel (chaired by the esteemed Roger Blandford) came up with from people much more knowledgeable about observational astronomy and indeed US Science Politics, so I won’t try to do a comprehensive analysis here. I draw your attention instead to the report itself  (which you can download in PDF form for free)  and Julianne Dalcanton’s review of, and comments on, the Panel’s conclusions about the priorities for  space-based and ground-based astronomy for the next decade or so over on Cosmic Variance.  There’s also a piece by Andy Lawrence over on The e-Astronomer’s blog. I’ll just mention that Top of the Pops for space-based astronomy is the Wide-Field Infrared Survey Telescope (WFIRST) which you can read a bit more about here, and King of the Castle for the ground-based programme is the Large Synoptic Survey Telescope (LSST). Both of these hold great promise for the area I work in – cosmology and extragalactic astrophysics – so I’m pleased to see our American cousins placing such a high priority on them. The Laser Interferometer Space Antenna (LISA), which is designed to detect gravitational waves, also did very well, which is great news for Cardiff’s Gravitational Physics group.

It will be interesting to see what effect – if any – these priorities have on the ranking of corresponding projects this side of the Atlantic. Some of the space missions involved in the Decadal Review in fact depend on both NASA and ESA so there clearly will be a big effect on such cases. For example, the proposed International X-ray Observatory (IXO) did less well than many might have anticipated, with clear implications for  Europe (including the UK).  The current landscape  of X-ray astronomy is dominated by Chandra and XMM, both of which were launched in 1999 and which are both nearing the end of their operational lives. Since X-ray astronomy can only be done from space, abandoning IXO would basically mean the end of the subject  as we know it, but the question is how to bridge the  the gap between the end of these two missions and the start of IXO even if it does go ahead but not until long after 2020? Should we keep X-ray astronomers on the payroll twiddling their thumbs for the next decade when other fields are desperately short of manpower for science exploitation?

On a more general level, it’s not obvious how we should react when the US gives a high priority to a given mission anyway. Of course, it gives us confidence that we’re not being silly when very smart people across the Pond endorse missions and facilities similar to ones we are considering over here. However, generally speaking the Americans tend to be able to bring missions from the drawing board to completion much faster than we can in Europe. Just compare WMAP with Planck, for instance. Trying to compete with the US, rather than collaborate, seems likely to ensure only that we remain second best. There’s an argument, therefore, for Europe having a programme that is, in some respects at least, orthogonal to the United States; in matters where we don’t collaborate, we should go for facilities that complement rather than compete with those the Americans are building.

It’s all very well talking of priorities in the UK but we all know that the Grim Reaper is shortly going to be paying a visit to the budget of the  agency that administers funding for our astronomy, STFC. This organization went through a financial crisis all of its very own in 2007 from which it is still reeling. Now it has to face the prospect of further savage cuts. The level of “savings” being discussed  – at least 25%  -means that the STFC management must be pondering some pretty drastic measures, even pulling out of the European Southern Observatory (which we only joined in 2002). The trouble is that most of the other ground-based astronomical facilities used by UK astronomers have been earmarked for closure, or STFC has withdrawn from them. Britain’s long history of excellence in ground-based astronomy now hangs in the balance. It’s scary.

I hope the government can be persuaded that STFC should be spared another big cut and I’m sure that there’s extensive lobbying going on.  Indeed, STFC has already requested input to its plans for the ongoing Comprehensive Spending Review (CSR). With this in mind, the Royal Astronomical Society has produced a new booklet designed to point out the  relevance of astronomy to wider society. However I can’t rid from my mind the memory a certain meeting in London in 2007 at which the STFC Chief Executive revealed the true scale of STFC’s problems. He predicted that things would be much worse at the next CSR, i.e. this one. And that was before the Credit Crunch, and the consequent arrival of a new government swinging a very large axe. I wish I could be optimistic but, frankly, I’m not.

When the CSR is completed then STFC will have yet again to do another hasty re-prioritisation. Their Science Board has clearly been preparing:

… Science Board discussed a number of thought provoking scenarios designed to explore the sort of issues that the Executive may be confronted with if there were to be a significant funding reduction as a result of the 2010 comprehensive spending review settlement. As a result of these deliberations Science Board provided the Executive with guidance on how to take forward this strategic planning.

This illustrates a big difference in the way such prioritisation exercises are carried out in the UK versus the USA. The Decadal Review described above is a high-profile study, carried out by a panel of distinguished experts, which takes detailed input from a large number of scientists, and which delivers a coherent long-term vision for the future of the subject. I’m sure not everyone agrees with their conclusions, but the vast majority respect its impartiality and level-headedness and have confidence in the overall process. Here in the UK we have “consultation exercises” involving “advisory panels” who draw up detailed advice which then gets fed into STFC’s internal panels. That bit is much like the Decadal Review. However, at least in the case of the last prioritisation exercise, the community input doesn’t seem to bear any obvious relationship to what comes out the other end. I appreciate that there are probably more constraints on STFC’s Science Board than it has degrees of freedom, but there’s no getting away from the sense of alienation and cynicism this has generated across large sections of the UK astronomy community.

The problem with our is that we always seem to be reacting to financial pressure rather than taking the truly long-term “blue-skies” view that is clearly needed for big science projects of the type under discussion. The Decadal Review, for example, places great importance on striking a balance between large- and small-scale experiments. Here we tend slash the latter because they’re easier to kill than the former. If this policy goes on much longer, in the long run we’ll end up a with few enormous expensive facilities but none of the truly excellent science that can be done from using smaller kit.  A crucial aspect of this that that science seems to have been steadily relegated in importance in favour of technology ever since the creation of STFC.  This must be reversed. We need a proper strategic advisory panel with strong scientific credentials that stands outside the existing STFC structure but which has real influence on STFC planning, i.e. one which plays the same role in the UK as the Decadal Review does in the States.

Assuming, of course, that there’s any UK astronomy left in the next decade…

The Shoe Event Horizon

Posted in Education, Politics, Science Politics with tags , , , , , on July 16, 2010 by telescoper

After yesterday’s  satisfying and enjoyable graduation festivities, it’s back to reality today with a clutch of scary news items about future cuts.

Vince Cable, the coalition Minister responsible for Universities, has revealed plans for Higher Education that include introducing a graduate tax and encouraging the growth of private universities,  the latter to be introduced at the expense of some current institutions which are to be allowed to go bankrupt. You can find some discussion of his speech in the Times Higher as well as in the Guardian piece I linked to earlier.

The graduate tax isn’t a new idea, but it does seem rather strange to be suggesting it right now. The proposal won’t lead to any significant income for universities in the short term so presumably either the government or the institutions themselves will have to borrow until the cash starts to flow in. But I thought we were supposed to be cutting public borrowing?

In fact, it seems to me that the announcements made by Cable are little more than a ragbag of ill-considered uncosted measures likely to do little but cause alarm across the Higher Education sector. Perhaps he would have been wiser to have kept the Ministerial trap shut until he’d actually worked out whether any of the half-baked ideas he announced were worth thinking through properly, as some of them just might be.

Apart from anything else, Vince Cable’s dramatic U-turn on Higher Education funding shows that the LibDem contingent have now been completely subsumed by the dominant right-wing, pro-market political stance of the Conservatives. In other words, we now know there’s no reason ever to vote LibDem again; they’re Tories in all but name.

I hope this year’s new graduates realised how lucky they’ve been to get their education before universities turn into Discount Education Warehouses, although I cling to the hope that the Welsh and Scottish assemblies might take a stand against if some of the worst aspects of the ConDem policy look like becoming reality in England, where the Tories live.

Meanwhile, the Royal Society has submitted its, er, submission to the ongoing debate about research funding. The headline in an accompanying article from the Times – which you won’t be able to read unless you give money to the Evil Empire of Murdoch – suggests that it could be “game over” for British science if the suggested cuts go ahead. Paul Crowther has done his usual fabulously quick job of hacking his way through the documentary jungle to get to the juiciest quotes, including this one:

Short-term budget cuts will put our long-term prosperity at risk.. The UK should maintain its breadth of research .. a flat cash settlement will be painful but manegeable; a 10% cash cut will be damaging .. while a 20% cut will be irreversibly catastrophic for the future of UK science and economic growth.

I’m sorry if I’m introducing a note of pessimism here, but I think we’ll be very lucky indeed if the cuts are as small as 20%.

And finally, not unexpectedly, the news this week includes an announcement that university staff are to have their pensions reduced and/or deferred and will have to pay more for the privilege. Employee’s contributions to the USS scheme will increase from 6% to 7.5%. For new members the pension will not be based on their final salary, but on average earnings. This isn’t a surprise as it’s been clear for some time that USS was actuarially unsound, but it’s one more sign of the forthcoming squeeze on academics, those of them that don’t get made redundant anyway…

Looking around for a bit of good news, I could only manage this. If you’re worried about the future of UK universities and scientific research then consider how lucky you are that you’re not Italian. Owing to budget cuts imposed by the Berlusconi regime, several Italian institutions will no longer be able to pay scientists’ wages. Responding to this situation the Italian premier replied with all his usual tact and intelligence:

Why do we need to pay scientists when we make the best shoes in the world?

Fans of the late Douglas Adams will be reminded of the following passage from The Restaurant at the End of the Universe:

Many years ago this was a thriving, happy planet – people, cities, shops, a normal world. Except that on the high streets of these cities there were slightly more shoe shops than one might have thought necessary. And slowly, insidiously, the number of the shoe shops were increasing. It’s a well-known economic phenomenon but tragic to see it in operation, for the more shoe shops there were, the more shoes they had to make and the worse and more unwearable they became. And the worse they were to wear, the more people had to buy to keep themselves shod, and the more the shops proliferated, until the whole economy of the place passed what I believe is termed the Shoe Event Horizon, and it became no longer economically possible to build anything other than shoe shops. Result – collapse, ruin and famine.

I see that Big Brother isn’t the only dystopian vision to have become reality, but perhaps Douglas Adams should have called his book The Restaurant at the End of the University?

Science versus Engineering?

Posted in Science Politics with tags , , , , , , on July 13, 2010 by telescoper

I suppose it was inevitable that there would be infighting as academics jostle for an increase intheir share of what is likely to be a diminishing level of research funding to be announced at the end of the ongoing Comprehensive Spending Review.  The first professional society to try to barge its way to the front of the queue appears to be the Royal Academy of Engineering, which has written to the Department of Business, Innovation and Skills (BIS) in terms that make it clear that they think egineering should prosper at the expense of research in fundamental physics.

To quote the RAEng:

we believe that research should be concentrated on activities from which a contribution to the economy, within the short to medium term, is foreseeable. I recognise that this calls for significant changes in practice but I see no alternative in the next decade. This may mean disinvesting in some areas in order properly to invest in others.

And where should the axe fall?

BIS should also consider the productivity of investment by discipline and then sub-discipline. Once the cost of facilities is taken into account it is evident that ‘Physics and Maths’ receive several times more expenditure per research active academic compared to those in ‘Engineering and Technology’. This ratio becomes significantly more extreme if the comparison is made between particle physics researchers and those in engineering and technology. Much of particle physics work is carried out at CERN and other overseas facilities and therefore makes a lower contribution to the intellectual infrastructure of the UK compared to other disciplines. Additionally, although particle physics research is important it makes only a modest contribution to the most important challenges facing society today, as compared with engineering and technology where almost all the research is directly or indirectly relevant to wealth creation.

Obviously whoever wrote this hasn’t heard of the World Wide Web, invented at CERN – precisely the place singled out for vitriol.

I couldn’t agree less with what the RAEng say in their submission to BIS, but instead of going on a rant here I’ll direct you to John Butterworth’s riposte, which says most of what I would want to say, but I would like to add one comment along the lines I’ve blogged about before.

The reason I think that the RAEng is precisely wrong is that I think the Treasury (on behalf of the taxpayer) should only be investing in research that wouldn’t otherwise be carried out. In other words, the state should fund academic esearch precisely because of its “blue sky” nature, not in spite of it.

Conversely, engineering and technology R&D should be funded primarily by the commercial sector precisely because it can yield short-term economic benefits. The decline of the UK’s engineering base has been caused by the failure of British companies to invest sufficiently in research, expecting instead that the Treasury should fund it and all they have to do is cash in later.

I’m not calling for the engineering and technology budgets to be cut – I don’t have such a blinkered view as the RAEng – but I would argue that a much greater share should be funded by private companies. This also goes for energy research. As Martin Rees pointed out in a recent Reith Lecture, the UK’s energy companies spend a pathetically small proportion of their huge profits on R&D. The politicians should be “persuading” industry to get invest more in the future development of their products rather than expecting the taxpayer to fund it. I agree that the UK economy needs “rebalancing” but part of the balance  is private companies need to develop a much stronger sense of the importance of R&D investment.

And, while I’m tut-tutting about the short-sighted self-interest displayed by the RAEng, let me add that, following the logic I’ve stated above,  I see a far stronger case for the state to support research in history and the arts than, e.g. engineering and computer science. I’d even argue that large commercial companies should think about sponsoring pure science in much the same way as they do with the performing art exhibitions and the Opera. We need as a society to learn to celebrate curiosity-driven research not only as a means to economic return (which it emphatically is) but also as something worth doing for its own sake.

Finally, and most depressingly of all, let me point out that the Chief Executive Officer of the Royal Academy of Engineering, Philip Greenish, sits on the Council of the Science and Technology Facilities Council, an organisation whose aims include

To promote and support, by any means, high-quality basic, strategic and applied research and related post-graduate training in astronomy, particle physics, space science and nuclear physics.

Clearly, he should either disown the statements produced by the RAEng or resign from STFC Council. Unless he was put there deliberately as part of the ongoing stitch-up of British physics. If that’s the case we all have the dole queue to look forward to.

Cardiff inSPIREs Willetts

Posted in Politics, Science Politics, The Universe and Stuff with tags , , , , on July 9, 2010 by telescoper

The Minister for Universities and Science David Willetts’ important speech today at the Royal Institution in London has already attracted a considerable amount of comment and reaction. I haven’t really got time to comment on it in detail, but in between the expected warning of tough times ahead, it does contain a great deal of extremely interesting and thoughtful material, which I recommend you read if you’re interested in science policy.

Of particular interest to us here in the School of Physics & Astronomy at Cardiff University is that we get a specific mention for the wonderful work done by the Astronomical Instrumentation Group on the development of the SPIRE instrument on the Herschel Space Observatory.  Everyone’s chuffed about it, and delighted that the Minister chose to highlight this particular example of excellence.

In my speech at Birmingham University in May, I spoke of links between the academic and the vocational, the conceptual and the physical. We are not always good at this – we have world-class particle physicists at the Large Hadron Collider but sadly not many British engineers helped to build it. But there are other areas where these links between British science and technology are stronger. We not only have distinguished astronomers, but it was scientists and engineers at Cardiff University who produced the Spectral and Photometric Imaging Receiver for Herschel and Planck. This combination of scientific research and technological advance creates extraordinary dynamism, both intellectual and commercial. I see it as one of my tasks to strengthen these links.

OK, so I know SPIRE wasn’t for “Herschel and Planck” but the AIG was involved with instruments for both these missions so the point is well made anyway.

Science as a Religion

Posted in Books, Talks and Reviews, Science Politics, The Universe and Stuff with tags , , , , , , , on July 6, 2010 by telescoper

With the reaction to Simon Jenkins’ rant about science being just a kind of religion gradually abating, I suddenly remembered that I ended a book I wrote in 1998 with a discussion of the image of science as a kind of priesthood. The book was about the famous eclipse expedition of 1919 that provided some degree of experimental confirmation of Einstein’s general theory of relativity and which I blogged about at some length last year, on its 90th anniversary.

I decided to post the last few paragraphs here to show that I do think there is a valuable point that Simon Jenkins could have made out of the scientist-as-priest idea. It’s to do with the responsibility scientists have to be honest about the limitations of their research and the uncertainties that surround any new discovery. Science has done great things for humanity, but it is fallible. Too many scientists are too certain about things that are far from proven. This can be damaging to science itself, as well as to the public perception of it. Bandwagons proliferate, stifling original ideas and leading to the construction of self-serving cartels. This is a fertile environment for conspiracy theories to flourish.

To my mind the thing  that really separates science from religion is that science is an investigative process, not a collection of truths. Each answer simply opens up more questions.  The public tends to see science as a collection of “facts” rather than a process of investigation. The scientific method has taught us a great deal about the way our Universe works, not through the exercise of blind faith but through the painstaking interplay of theory, experiment and observation.

This is what I wrote in 1998:

Science does not deal with ‘rights’ and ‘wrongs’. It deals instead with descriptions of reality that are either ‘useful’ or ‘not useful’. Newton’s theory of gravity was not shown to be ‘wrong’ by the eclipse expedition. It was merely shown that there were some phenomena it could not describe, and for which a more sophisticated theory was required. But Newton’s theory still yields perfectly reliable predictions in many situations, including, for example, the timing of total solar eclipses. When a theory is shown to be useful in a wide range of situations, it becomes part of our standard model of the world. But this doesn’t make it true, because we will never know whether future experiments may supersede it. It may well be the case that physical situations will be found where general relativity is supplanted by another theory of gravity. Indeed, physicists already know that Einstein’s theory breaks down when matter is so dense that quantum effects become important. Einstein himself realised that this would probably happen to his theory.

Putting together the material for this book, I was struck by the many parallels between the events of 1919 and coverage of similar topics in the newspapers of 1999. One of the hot topics for the media in January 1999, for example, has been the discovery by an international team of astronomers that distant exploding stars called supernovae are much fainter than had been predicted. To cut a long story short, this means that these objects are thought to be much further away than expected. The inference then is that not only is the Universe expanding, but it is doing so at a faster and faster rate as time passes. In other words, the Universe is accelerating. The only way that modern theories can account for this acceleration is to suggest that there is an additional source of energy pervading the very vacuum of space. These observations therefore hold profound implications for fundamental physics.

As always seems to be the case, the press present these observations as bald facts. As an astrophysicist, I know very well that they are far from unchallenged by the astronomical community. Lively debates about these results occur regularly at scientific meetings, and their status is far from established. In fact, only a year or two ago, precisely the same team was arguing for exactly the opposite conclusion based on their earlier data. But the media don’t seem to like representing science the way it actually is, as an arena in which ideas are vigorously debated and each result is presented with caveats and careful analysis of possible error. They prefer instead to portray scientists as priests, laying down the law without equivocation. The more esoteric the theory, the further it is beyond the grasp of the non-specialist, the more exalted is the priest. It is not that the public want to know – they want not to know but to believe.

Things seem to have been the same in 1919. Although the results from Sobral and Principe had then not received independent confirmation from other experiments, just as the new supernova experiments have not, they were still presented to the public at large as being definitive proof of something very profound. That the eclipse measurements later received confirmation is not the point. This kind of reporting can elevate scientists, at least temporarily, to the priesthood, but does nothing to bridge the ever-widening gap between what scientists do and what the public think they do.

As we enter a new Millennium, science continues to expand into areas still further beyond the comprehension of the general public. Particle physicists want to understand the structure of matter on tinier and tinier scales of length and time. Astronomers want to know how stars, galaxies  and life itself came into being. But not only is the theoretical ambition of science getting bigger. Experimental tests of modern particle theories require methods capable of probing objects a tiny fraction of the size of the nucleus of an atom. With devices such as the Hubble Space Telescope, astronomers can gather light that comes from sources so distant that it has taken most of the age of the Universe to reach us from them. But extending these experimental methods still further will require yet more money to be spent. At the same time that science reaches further and further beyond the general public, the more it relies on their taxes.

Many modern scientists themselves play a dangerous game with the truth, pushing their results one-sidedly into the media as part of the cut-throat battle for a share of scarce research funding. There may be short-term rewards, in grants and TV appearances, but in the long run the impact on the relationship between science and society can only be bad. The public responded to Einstein with unqualified admiration, but Big Science later gave the world nuclear weapons. The distorted image of scientist-as-priest is likely to lead only to alienation and further loss of public respect. Science is not a religion, and should not pretend to be one.

PS. You will note that I was voicing doubts about the interpretation of the early results from supernovae  in 1998 that suggested the universe might be accelerating and that dark energy might be the reason for its behaviour. Although more evidence supporting this interpretation has since emerged from WMAP and other sources, I remain skeptical that we cosmologists are on the right track about this. Don’t get me wrong – I think the standard cosmological model is the best working hypothesis we have _ I just think we’re probably missing some important pieces of the puzzle. I don’t apologise for that. I think skeptical is what a scientist should be.

All in a day’s work

Posted in Art, Biographical, Education, Science Politics, The Universe and Stuff with tags , , , , , on June 30, 2010 by telescoper

I got back from yesterday’s trip to a very muggy London with a raging sore throat and a brain as sluggish as an England defender on an action replay. Come to think of it, I must be as sick as a parrot. I’m sweating like a pig too, although I don’t know whether that’s a symptom of anything nasty or just because it’s still so warm and humid. Anyway, in view of my likely incoherence I thought I’d keep it brief (again) and just mention a few salient points from the last day or two.

I went to London as part of my duties as External Examiner for the MSc Course in Astrophysics at Queen Mary, University of London. Of course all the proceedings are confidential so I’m not going to comment on anything in detail, except that I spent a bit of time going through the exam scripts before the Examiners’ Meeting in a room that did a very passable impersonation of a heat bath. When I was later joined by the rest of the Exam Board the temperature soared still further. Fortunately the business went relatively smoothly so nobody got too hot under the collar and after concluding the formal business, a few of us cooled off with a beer or two in the Senior Common Room.The students spend the next couple of months writing their dissertations now that the written exams are over, so we have to reconvene in October to determine the final results. I hope it’s a bit cooler by then.

I couldn’t stay long at Queen Mary, however, as I had a working dinner to get to. Regular readers of this blog (both of them) may remember that I’m involved in project called Beyond Entropy which is organized by the Architectural Association School of Architecture. I’ve been working on this occasionally over the months that have passed since I first blogged about it, but deadlines are now looming and we need to accelerate our activity. Last night I met with the ever-enthusiastic Stefano Rabolli Pansera at the house of Eyal Weizman by Victoria Park in the East End, handily close to Queen Mary’s Mile End campus. Assisted by food and wine we managed to crystallise our ideas into something much more tangible than we had managed to do before on our theme of Gravitational Energy. The School has offered us expert practical assistance in making prototypes and  I’m now much more optimistic about our exhibit coming together, not to mention excited at the prospect of seeing it on display at the Venice Architecture Biennale. I won’t say what we’re planning just yet, though. I’d rather wait until it’s done before unveiling it.

Incidentally, here’s a link to a  lecture by Eyal Weizman where he gives some interesting perspectives on architectural history.

Finally, and nothing to do with my trip to the Big Smoke, I noticed today on the Research Fortnight Blog that the Higher Education Funding Council for Wales (HEFCW) is planning to reduce the number of universities in Wales “significantly” from its current level of 12. This is an interesting development and one that I’ve actually argued for here. Quoting Leighton Andrews, Welsh Assembly Minister responsible for higher education, the piece says

“This target does not mean fewer students,” he said in a statement. “But it is likely to mean fewer vice chancellors. We will have significantly fewer HE institutions in Wales but they will be larger and stronger.”

How these reductions will be achieved remains to be seen, but it seems obvious that quite a few  feathers will be ruffled among the management’s plumage in some institutions and it looks like some vice chancellors will be totally plucked!

Spoof Positive?

Posted in Science Politics, Uncategorized with tags , on June 29, 2010 by telescoper

Only time for a brief post today, as I’m shortly off to London for some external examining in the East End.

It’s interesting that yesterday’s #SpoofJenks day generated so many contributions that the Guardian decided to get the main instigator, particle physicist Jon Butterworth, to write about it on their Science Blog.  My own contribution of yesterday gets a mention there too.

I have to say I found the whole thing very amusing and wholeheartedly agree with Jon Butterworth (whose original spoof started it all off) when he explained that his primary aim was more to let off steam and less to try to persuade Simon Jenkins of the error of his ways. I felt the same way. Better to poke fun back than allow him to get to you.

I didn’t feel parody was necessary in Simon Jenkins’ case because his arguments are full of factual errors and non sequitur. In fact, it did occur to me that his piece might be deliberately ironic. Could one of the prime movers behind the Millennium Dome really be serious when he talks about the wastefulness of CERN? Perhaps he’s spoofed us all. But even that wouldn’t excuse his snide personal attack on Martin Rees.

Anyway, as you will have noticed, I  just went for straight mockery and had a good half-an-hour of lunchtime fun writing it.  A few people seem to have liked my piece, but at least one blogger found it “unpleasant”. You can’t win ’em all. For what it’s worth, I still think he deserved it.

In fact, I posted a considerably less vitriolic reaction to Jenkins article on Saturday, but trying to respond in rational terms was something I found very frustrating. Only a few hundred people read this blog so it’s pretty futile to try to take on a columnist from a national newspaper that’s read by hundreds of thousands. I’m not sure he’s listening anyway, as he’s written similar drivel countless times before. Far better, in my view, to join the collective piss-taking. At least it got the Guardian interested.

Maybe after all this Jenkins will actually engage in a dialogue with scientists instead of merely insulting them? Perhaps. But I’m not holding my breath.

The Song of the Lyre Bird

Posted in Biographical, Science Politics, The Universe and Stuff with tags , , , , , , , on June 25, 2010 by telescoper

I’ve wanted to post this little clip for some time, just because it’s so marvellous.

I wonder what you felt as you watched it?  What went through your mind? Amusement? Fascination?  I’ll tell you how it was for me when I first saw it.  I marvelled.

Seeing the extraordinary behaviour of this incredible creature filled me with a sense of wonder. But I also began to wonder in another sense too. How did the Lyre Bird evolve its bizarre strategy? How does it learn to be such an accurate mimic? How does it produce such a fascinating variety of sounds? How can there be an evolutionary advantage in luring a potential mate to the sound of foresters and a chainsaw?

The Lyre Bird deploys its resources in such an elaborate and expensive way that you might be inclined to mock it, if all it does is draw females to “look at its plumes”.  I can think of quite a few blokes who adopt not-too-dissimilar strategies, if truth be told. But if you could ask a Lyre Bird it would probably answer that it does this because that’s what it does. The song defines the bird. That’s its nature.

I was moved to post the clip in response to a characteristically snide and ill-informed piece by Simon Jenkins in yesterday’s Guardian. Jenkins indulges in an anti-science rant every now and again. Sometimes he has a point, in fact. But yesterday’s article was just puerile. Perhaps he had a bad experience of science at school and never got over it.

I suppose I can understand why some people are cynical about scientists stepping into the public eye to proselytise about science. After all, it’s also quite easy to come up with examples of  scientists who have made mistakes. Sadly, there are also cases of outright dishonesty. Science is no good because scientists are fallible. But scientists are people, no better and no worse than the rest. To err is human and all that.  We shouldn’t expect scientists to be superhuman any more than we should believe the occasional megalomaniac who says they are.

To many people fundamental physics is a just a load of incomprehensible gibberish, the Large Hadron Collider a monstrous waste of money, and astronomy of no greater value to the world than astrology. Any scientist trying to communicate science to the public must be trying to hoodwink them, to rob them of the schools and hospitals that their taxes should be building and sacrifice their hard-earned income on the altar of yet another phoney religion.

And now the BBC is participating in this con-trick by actually broadcasting popular programmes about science that have generated huge and appreciative audiences. Simon Jenkins obviously feels threatened by it. He’s probably not alone.

I don’t  have anything like the public profile of the target of Jenkins’ vitriol, Lord Rees, but I try to do my share of science communication. I give public lectures from time to time and write popular articles, whenever I’m asked. I also answer science questions by email from the general public, and some of the pieces I post on here receive a reasonably wide distribution too.

Why do I (and most of my colleagues) do all this sort of stuff? Is it because we’re after your money?  Actually, no it isn’t. Not directly, anyway.

I do all this stuff because, after 25 years as a scientist, I still have a sense of wonder about the universe. I want to share that as much as I can with others. Moreover,  I’ve been lucky enough to find a career that allows me to get paid for indulging my scientific curiosity and I’m fully aware that it’s Joe Public that pays for me to do it. I’m happy they do so, and happier still that people will turn up on a rainy night to hear me talk about cosmology or astrophysics. I do this because I love doing science, and want other people to love it  too.

Scientists are wont to play the utilitarian card when asked about why the public should fund fundamental research. Lord Rees did this in his Reith Lectures, in fact. Physics has given us countless spin-offs – TV sets, digital computers,  the internet, you name it – that have created wealth for UK plc out of all proportion to the modest investment it has received. If you think the British government spends too much on science, then perhaps you could try to find the excessive sum on this picture.

Yes, the LHC is expensive but the cost was shared by a large number of countries and was spread over a long time. The financial burden to the UK now amounts to the cost of a cup of coffee per year for each taxpayer in the country. I’d compare this wonderful exercise in friendly international cooperation with the billions we’re about to waste on the Trident nuclear weapons programme which is being built on the assumption that international relations must involve mutual hatred.

This is the sort of argument that gets politicians interested, but scientists must be wary of it. If particle physics is good because it has spin-offs that can be applied in, e.g. medicine, then why not just give the money to medical research?

I’m not often put in situations where I have to answer questions like why we should spend money on astronomy or particle physics but, when I am, I always feel uncomfortable wheeling out the economic impact argument. Not because I don’t believe it’s true, but because I don’t think it’s the real reason for doing science. I know the following argument won’t cut any ice in the Treasury, but it’s what I really think as a scientist (and a human being).

What makes humans different from other animals? What defines us? I don’t know what the full answer to that is, or even if it has a single answer, but I’d say one of the things that we do is ask questions and try to answer them. Science isn’t the only way we do this. There are many complementary modes of enquiry of which the scientific method is just one. Generally speaking, though, we’re curious creatures.

I think the state should support science but I also think it should support the fine arts, literature, humanities and the rest, for their own sake. Because they’re things we do. They  make us human. Without them we’re just like any other animal that consumes and reproduces.

So the real reason why the government should support science is the song of the Lyre Bird.  No, I don’t mean as an elaborate mating ritual. I don’t think physics will help you pull the birds. What I mean is that even in this materialistic, money-obsessed world we still haven’t lost the  need to wonder, for the joy it brings and for the way it stimulates our minds; science doesn’t inhibit wonder, as Jenkins argues,  it sparks it.

Now, anyone want to see my plumes?

Stay of Execution

Posted in Education, Finance, Politics, Science Politics with tags , , , , on June 22, 2010 by telescoper

Another beautiful summer’s day here in Cardiff just happened to be the day when the new ConDem government unleashed its much-feared budget. I suppose we were all expecting some combination of  tax rises and spending cuts but nodody I know had managed to predict the details. A big rise in VAT (to 20%) is the headline figure most of the newspapers seem to be running with, but the other side is the one that caught my eye;  average cuts of 25% in “unprotected” Whitehall departments. That means basically everything outside Health and Education, and “Education” doesn’t include Higher Education which falls within the remit of the Department of Business Innovation and Skills.  Universities (in England; Scotland, Wales and Northern Ireland run their own budgets for HE) and the Research Councils are therefore bracing themselves for cuts of 25% or even more; if some departments are cut less than this average, then some will be cut more…

For informed comment, see here and here.

However, the details of how these cuts will be implemented – and, of particular relevance to me, how much the Science and Technology Facilities Council will be chopped – will have to wait until the Comprehensive Spending Review to be announced in October 2010. No doubt the STFC Executive will be using all their political skills and powers of persuasion to argue for a positive settlement. Like they did last time. In other words, we’re doomed.

Incidentally, you can hear Lord Rees’ scathing comments about the inept management of STFC here, although to so involves shaking hands with the devil that is iTunes.

There’s also a two-year freeze on public sector salaries – again, not entirely unexpected – but obviously that will only apply to those who keep their jobs after the departmental budgets are cut by a quarter.

Anyway, no point in griping. We all knew this was coming. The big question now is whether the increases in unemployment and tax rises will stop our feeble economic recovery in its tracks, and how badly the cuts in investment will jeoparside future growth. I’m not sufficiently knowledgeable about economics to comment sensibly on this.

Coincidentally today was also the day that STFC Council met here in Cardiff. Of course they did so behind closed doors, but they also had a quick tour of the buildings and a briefing by our Head of School, Swiss Tony Walter Gear. I’m told one of the Council members asked “Excuse me, but what is Planck?”. Apparently the question was posed by one of the non-scientists on STFC Council. So that’s alright then.

Still, there’s always the elimination of France from the World Cup to gladden the heart of an Englishman. Like STFC, the England  football team will learn its fate soon eough …

Signs of the Times

Posted in Biographical, Science Politics, The Universe and Stuff with tags , , , on June 5, 2010 by telescoper

Well, I’m back from sunny Copenhagen to a very muggy Cardiff. I arrived by train just as this afternoon’s rugby match between Wales and South Africa finished so I got caught up in the crowds and had to follow a lengthy diversion to get home. I was a bit tetchy with the heat and feeling a bit tired, but feel a bit mellower now after a nice shower. Apparently it was a cracking game, with Wales losing narrowly to the Springboks in the end. I missed it all.

Not feeling like doing anything more energetic blogwise, I thought I’d just put up a few pictures of the trip before making dinner. I heard while I was in Copenhagen that there are plans to relocate the historic Niels Bohr Institute to new accommodation nearby. I’m very attached to the old place and I think it will be a terrible shame if the original buildings are flogged off or bulldozed. I believe that’s not going to happen but I’m not sure what their fate is going to be. Anyway, I asked one of the locals, Tamara Davis, to take a picture in front of the sign outside the old NORDITA  building, looking grumpy, to show my disapproval. I think she caught the mood perfectly.

Actually, Tamara isn’t really a local because she’s Australian, but she spends a couple of months a year in Denmark at the Dark Cosmology Centre, which is about ten minutes’ walk from the Niels Bohr Institute. I sat next to her at the conference dinner and found out that she’s also an international quality Ultimate Frisbee player. I wish I could pretend I knew what that was, but it sounds impressive. The fact that she’s training for a major event at the moment meant that she wasn’t drinking much wine so, being a gentleman, I drank the surplus on her behalf.

I wonder if there’s such a sport as Penultimate Frisbee?

Here’s another picture in front of the same building, featuring some folks from the workshop.

From left they are Dominik Schwarz (Bielefeld, Germany), Anthony Lasenby (Cambridge, UK), Carlo Burigana (Bologna, Italy),  Sabino Matarrese (Padova, Italy) and Paolo Natoli (Rome, Italy).

Last one shows the view in the evening sun looking down towards the picturesque old harbour area, called Nyhavn. I took this in anticipation of a nice cold beer among the crowds of people out enjoying themselves in the lovely weather. I wasn’t disappointed!
