Commented out

Interesting. Very interesting.

You may recall that a few days ago, the Times Higher closed the comments section on their story about Mark Brake, the University of Glamorgan Professor who falsely represented his credentials on a grant application in 2006 by claiming to have a PhD. This is an ongoing story on this blog – see previous posts here, here and here – and I had been logging the comments for future reference. I was worried that the comments might be lost when the Times Higher closed them so I posted them on this blog. I took them offline a bit later because I was worried about possible copyright infringement, but also made several copies which I have lodged in various places for safekeeping.

When I got back home yesterday I spent a bit of time catching up on blog administration and found that the page of Times Higher comments (which was still on my wordpress space, but not available to the public) had been marked “DO NOT REPOST – CONTACT SUPPORT”. I did so, and it was explained to me that they had received a complaint containing the following

.. this post is actually a repost of an entire conversation held on the Times Higher Education Supplement website, which was removed earlier today after the editor there decided that the contents had become too abusive, and was in breach of not only their own sites rules against defamation and liable, but also in breach of several telecommunications acts here in the UK as well as consituting an invasion of privacy into the lives of several people.

Since the Times Higher hadn’t given a reason for deleting the comments thread on its own site, I asked them whether these indeed were the reasons they had removed them and whether they had made this complaint. I suspected not, as for one thing I was sure that employees of  said organ would be able to spell “libel” correctly. Had they – or anyone else – approached me directly with a  good reason I would have been happy to remove them. As it happens nobody contacted me personally about this, and I was a bit annoyed at the underhand way that it was done. Not the only underhand thing that has happened recently in connection with this story.

I received a reply from Phil Baty, one of the editors of the THES, who confirmed that they had decided to close the thread after “complaints” but had not made any approach about my use of the THES comments on this site. He also  stated that

the decision to close the thread should not be taken as any judgement on our part on the behaviour of any individual who posted.

The anonymous complainant thus seems to have deliberately misrepresented the situation to WordPress in order to suppress the contents of my blog page. Sneaky.

Neither WordPress nor the Times Higher would reveal the identity of the complainant, but I can guess. I surmise this was done by an individual anxious to hush up this story and to conceal his identity. I wonder who that might be?

Anyway, the main point of this post is to reassure those at the University of Glamorgan responsible for disciplinary matters that the abusive comments posted on the THES  have not been lost so there’s no reason to give up their investigation into the ongoing serious misconduct of its employees. I’d be delighted to hand over the information if they request it as part of their no doubt strenuous efforts to root out those responsible for bringing their name into disrepute.

I’m sure the University of Glamorgan would have been very upset if  such important evidence of ongoing wrongdoing had been lost so I am happy to be able to allay their fears.

Perhaps the University of Glamorgan might also like to establish whether any of its employees used a deliberate falsehood to persuade WordPress to suppress this evidence? Shouldn’t be too difficult.

PS. I note the recent news that the University of Glamorgan is to get a new Vice-chancellor.

Negative Impact

Posted in Science Politics with tags , , , , , on December 2, 2009 by telescoper

After spending the best part of the last couple of days being prodded and poked and subjected to all manner of indignity in the name of medical science, I think it’s appropriate to return to the blogosphere with another rant. Before I start, however, I’d seriously like to thank everyone at the University Hospital of Wales at Heath Park  for making my visit there as brief and painless as possible. Everyone was very kind and very efficient. I’m not going to blog about the details, as Columbo doesn’t like reading about other peoples’ ailments.

Over the past few weeks there has been a lot of discussion about the UK government’s agenda for research, particularly science research, that includes something called “impact”. The Research Excellence Framework (REF; successor to the Research Assessment Exercise, RAE) will include such a thing:

Significant additional recognition will be given where researchers build on excellent research to deliver demonstrable benefits to the economy, society, public policy, culture and quality of life

Apparently, however, they don’t really know how to do this so they have set up a number of pilot studies to try to find out. I’d feel a little more comfortable if the bureaucrats had thought about what they were going to do before announcing that our future research funds were going to depend on it. Meanwhile, applicants for grants from any of the research councils must  include a statement of the “economic or social” impact their research will have.

Understandably, those of us working in “blue skies” research are very nervous about this new regime. There is more than a suspicion that the new emphasis on impact is intended to divert funds away from “pure” curiosity driven research and into areas where it can have an immediately identifiable short-term economic benefit. This has led to a petition, with over 13000 signatures, by the University and College Union calling for the impact statements to be abandoned.

I don’t know who is going to assess these impact statements, but unless they have a flawless ability to predict future technology I don’t think fundamental physics is going to score very well at all. To see my point, consider the case of  J. J. Thomson, who is generally credited with having discovered the electron and who was awarded the Nobel Prize for Physics in 1906. Thomson made extensive use of cathode ray tubes in his studies; these later found their way into sitting rooms across the world as essential components of the classic television set. But that took decades. I doubt if an impact panel looking at Thomson’s work – even if they were physicists rather than grey-suited bureaucrats – would have found any of it likely to lead to immediate economic benefit. The point is that when he discovered the electron it wasn’t because he was actually trying to invent the television set.

I think there are basically two possible interpretations of this impact business. One is that it is a deliberate plan to wind down fundamental research and use the money saved to subsidise UK industry. The other is that it’s another exercise in pointless box-ticking. I am in two minds. On the one hand, it is clear that the recent behaviour of the Science and Technology Facilities Council shows strong evidence of the former. Fundamental research is being slashed, yet projects involving space technology have been funded on the nod without scientific  peer review. On the other hand, the RCUK Impact “Champion”, a person by the name of David Delpy, has written in the Times Higher to defend the new agenda. Consider the following paragraph

Recently I have read that some believe it is impossible to predict the economic impact of blue-skies research. To be clear, we are not asking for accurate predictions – simply a consideration of potential. Basic research underpins all disciplines and builds pathways to new technologies with economic and social applications. It may build on an existing body of knowledge, connect to other research around the world or attract new industries to the UK. There are many routes to impact. I believe that I could write a statement indicating potential impact for any proposal I have seen, and to hear that bright academics say they can’t do it sounds a little disingenuous.

Champion Delpy thus suggests he could write a statement for any proposal he has seen, which sounds to me like an admission that what is called for is just a load of flannel. In fact, if he’s paid to be the Impact Champion perhaps he should write all the bullshit and save us scientists the need to jump through these silly hoops? Or perhaps we could get one of those little Microsoft Office Assistant things:

Hello. Looks like you’re writing an Impact Assessment. Would you like me to pad it out with meaningless but impressive-looking socio-economic buzzwords for you?

If it’s just another exercise in vacuous bureaucracy then it’s bad enough, but if it is the other possibility then of course it’s even worse. It could be the end for disciplines like astronomy and particle physics as well as the end of Britain’s history of excellence in those areas. I’ve already blogged about my view of short-termism in research funding. Essentially, my point is that government money should be used to fund precisely those things that don’t have immediate economic benefit. Those that do should be funded by the beneficiaries, i.e. commercial companies.

Politicians probably think that all this complaining about impact means that scientists  are arrogantly assuming that the taxpayer should fund them regardless of the cost or the benefit. I can only speak for myself, but I think that’s very unfair. I’m very conscious that my research is funded by Joe Public; that’s one of the reasons I think I should spend time giving public talks and doing other outreach activities. But I think the public funds me and others like me to do “useless” things because, in the end, useless things are more important than money.

The government is probably right to say that the UK economy doesn’t benefit as much from our scientific expertise as is the case with other countries. The reason for that, however, lies not with our universities and research laboratories but with our private industrial and commercial sectors which are, for the most part, managed with a very low level of competence. British universities are demonstrably excellent; our industry is demonstrably feeble. The persistent failure of the private sector to invest in research and development shows that it is in drastic need of a good shake up. British companies, not the taxpayer, should be paying for research that leads to profit for them and for that to happen they will have to learn to engage better with the University sector rather than expecting inventions to be served up on a plate funded by the taxpayer. Universities and research labs should continue do what they’re good at,  maintaining a culture within which curiosity and learning are promoted for their own sake not just as part of the dreary materialistic cycle of production and consumption that is all we seem to be able to think about these days.

So at the end I’ve come to the conclusion that, perhaps, insofar as it can be demonstrated, economic impact should be included in the forthcoming Research Excellence Framework. Research which leads directly to the economic gain of the private sector is  precisely the type of research that the taxpayer should not be paying for. If it can be proven that a given department has engaged in such activity, its state funding should therefore be cut and it should be told to recover the funds it has misused from the company that has benefitted from it. Economic impact should be included with a negative weight.

And if you think that’s a silly point of view, consider what happens with the other major part of a university’s activity, teaching. Students, we are told, are the primary beneficiaries of their education so they should have to pay fees. In the current regime, however, they only do so when their earnings reach a certain level. If commercial companies are to be the primary beneficiaries of state-funded research, why should they not likewise be asked to pay for it?

Interlude

Owing to foreseen circumstances I’m going to be spending the next few days enjoying the hospitality (geddit?) of our wonderful National Health Service which is the envy of the civilised world (and America).

Normal services will be resumed as soon as possible but, for the time being, there will now follow a short intermission.

Blood Count

Posted in Jazz with tags , , , on November 29, 2009 by telescoper

Yesterday I was listening to Jazz Record Requests on BBC Radio 3 and a piece cropped up that reminded me that today, 29th November 2009, would have been the 94th birthday of the great composer and arranger Billy Strayhorn.

The piece that came up wasn’t specifically chosen to mark Strayhorn’s birthday but I thought I’d put it up here because it is so beautifully poignant.  Strayhorn collaborated extensively with Duke Ellington over the years, producing some of the most gorgeous music to emerge from the 20th century in any genre.

Although apparently started some time earlier, Blood Count was the last piece completed by Billy Stayhorn who put the final touches to it while he was in hospital suffering from a terminal cancer. It was first performed after his death in 1967 by Duke Ellington’s orchestra as a tribute, with Johnny Hodges‘  alto sax taking the lead. Hodges was never a speed merchant on the alto sax, but his big warm sound, beautiful tone and poised lyricism won him huge admiration from all parts of the jazz spectrum, including John Coltrane who described him as “The World’s Greatest Saxophone Player”. High praise indeed, but listening to this performance it’s hard to disagree! Heartfelt but dignified, it’s not just a fitting eulogy for Strayhorn, but a lovely piece in its own right.

Well, you’ll either love this or hate it. If you’re of a certain age like me you might  also remember that happiness is a cigar called Hamlet but not remember who played the tune. This is, fact, Jacques Loussier and his trio doing their take on Johann Sebastian Bach. And before you get too sanctimonious and music-hysterical about this version, I’ll just add that it is well known that Bach enormously enjoyed improvisation. I have a sneaking feeling he would actually have quite liked this…

Spire Spectra

Posted in The Universe and Stuff with tags , , , , , , on November 27, 2009 by telescoper

OK, so it turns out I lied about not posting today. It’s not because I’m a dishonest professor, though. It’s just that I couldn’t resist drawing your attention to the new results that have just been released by the European Space Agency. To whet your appetite, have a shufty at this exquisite far infrared spectrum of the star VY Canis Majoris taken using the SPIRE instrument for which Cardiff is the lead institute.

VY Canis Majoris (VY CMa) is a red hypergiant, an enormous evolved star located in the constellation Canis Major. With a radius 2600 times that of the Sun, it is the largest known star and it is also one of the most luminous stars known. It is located about 4900 light years away from Earth, has a luminosity in excess of 100,000  solar luminosities, and a mass in the range 30-40 solar masses.

The shell of gas it has ejected displays a complex structure, the so-created circumstellar envelope is among the most remarkable chemical laboratories known in the universe, creating a rich set of organic and inorganic molecules and dust species. Through stellar winds, these inorganic and organic compounds are injected into the interstellar medium, from which new stars orbited by new planets may form. Most of the carbon supporting life on planet Earth was probably made by this kind of evolved star. VY CMa is close to the end of its life and could explode as a supernova at any time.

Spectroscopic results may be a bit less photogenic than pretty pictures, but they often yield much more physically relevant information than simple images. As I’ve mentioned before, it is in spectroscopy where we find the difference between astronomy and astrophysics (or, less politely, between stamp collecting and science).  In this case the spectrum gives a detailed breakdown of the chemical mixture present in the matter ejected by this star.

You can find other stunning examples of Herschel’s infrared spectroscopic capabilities here and you can read more about the involvement of Cardiff astronomers in these stunning new science results on our own pages here.

There’s also a story on the BBC Website.

Brake Thread

Posted in Uncategorized with tags , , , on November 26, 2009 by telescoper

Following my post yesterday, the thread of comments relating to the Mark Brake/University of Glamorgan fraud scandal has been removed from the Times Higher story. However, I was logging the thread until very near the end (in fact, until my own  last comment this morning shortly before the comments were closed). I have posted them on a permanent page here to preserve them, but the page is currently offline pending clarification of copyright issues.

I have no idea why the comments were deleted, but I hope it is a sign that the University of Glamorgan is finally investigating this matter. If they are, I expect this matter to reach a speedy conclusion. If not, I will keep you posted on further developments with this and other matters in due course.

I’ve decided to reduce the amout of blogging I do over the next few days to catch up on paper-writing and a few other things, but I don’t think it’s a bad thing if story stays at the top of the page for now.

The Mark Brake Story

Posted in Uncategorized with tags , , , on November 25, 2009 by telescoper

I’m quite surprized to find myself posting yet another item about this story over a month after I originally mentioned it, but after the events of the last few days I really don’t feel like letting it drop.

In case you missed the story first time, Professor Mark Brake (he of the absurdly glowing wikipedia page) falsely represented his qualifications when applying for a research grant in 2006. For some reason, his employer – the University of Glamorgan – did not take the appropriate action of dismissing him for gross misconduct, but instead sacked the person responsible for drawing it to their attention. These are the facts as reported in the Times Higher Education Supplement which I commented on in my second post on this saga a few weeks ago.

The reason for posting about it again is that the Times Higher article is attracting a truly phenomenal number of comments (nearly 600 at the last count). These, roughly speaking, divide into two camps. The first set (including 4 comments by myself under my own name) comprises comments from people dismayed by the fact that Professor Brake’s misconduct appears not to have been investigated properly by the UoG and suggestions that this episode will reflect badly on academia generally unless  it can be sorted out promptly.

The second camp appears to consist of a small number of individuals posting abusively mocking comments under a variety of silly pseudonyms who are clearly attempting to draw attention away from the allegations against Professor Brake. It seems to me to be a very high probability that the culprit himself is behind many of the more absurd comments on the thread. I have been informed by someone working for the University of Glamorgan that Brake has been expressly forbidden to comment on this story, but that the UoG has taken no steps whatsoever to investigate whether he is doing so. In the meantime, contrary to promises made by their press contact to the THES, the UoG  have not yet made any attempt investigate the original misconduct. To quote from a comment I put on the thread myself:

I wish I shared the confidence of some other posters in the willingness of the UoG to treat this matter with appropriate seriousness. I think it is more likely that their “investigation” involves keeping their eyes firmly closed and not opening them unless and until a third party drops a load of direct evidence on their head. The longer they continue to ignore the ongoing misconduct of their own employees, including their abusive posts on this thread, the further the reputation of the University of Glamorgan is tarnished.

Since I revealed that I  that passed the Wales Online story onto the Times Higher, a number of things have happened which I can’t comment on for legal reasons. These events have left me very doubtful that the University of Glamorgan intends to investigate this matter at all and wishes instead that it will all blow over.

Of course readers of this blog can form their own opinions about the importance of this case and/or my interpretation of the facts but, based on what I know, I have drawn the conclusion that it is very important that this matter is not allowed to fade away. For one thing, the professorial salary of this individual is funded by the taxpayer….

I therefore intend to keep posting comments on the THES in support of academic standards and against academic misconduct until something is done. I invite any readers that agree with me to post their comments on the THES thread.

If representatives of the University of Glamorgan or any individual or organization feels I have misrepresented any aspect of this case or if you disagree with me for any other reason, or simply wish to comment, please feel free to express your thoughts through the box below.

STOP PRESS: The Times Higher appears to have closed the thread on this story for reasons not explained. You may still comment here of course.

Black Hole

Posted in Poetry, The Universe and Stuff with tags , , , on November 24, 2009 by telescoper

After an exceptionally trying day, I’ve been relaxing by dipping into a collection of poems called Dangerous Driving by Chris Woods. He’s an interesting character who works part-time as a GP in Lancashire and tries to balance medicine, family and writing. His poetry has appeared in numerous magazines and newspapers and has also been broadcast on BBC Radio and Channel Four Television (including a series called Six Experiments that Changed the World, to which I was also a contributor).

Anyway I’ve developed  a bit of a habit of putting up poems with vaguely astronomical themes so when I found this one, I decided to put it up here not least because it made me think of the person who has been causing me so much hassle over the past few days….

Black Hole

You turn all the lights off
but never sleep,
pace round the edge of yourself,
never communicate.
A million dark years distant,
you suck in light like spaghetti.

You got too big for yourself
and collapsed,
but ferocious energy remained
and now you’re back, muscling in
carving out your own space
and time.

You smash up your neighbourhood,
pull the light off stars.
Masked,
you are far outside our laws,
giving nothing away,
stealing everything from everything.

(reproduced with the kind permission of Comma Press).

You can also see a video based on the poem Black Hole from Ghost Code on Vimeo although I have to admit I could make neither head nor tail of it.

The Cosmic Web

Posted in The Universe and Stuff with tags , , , , , on November 23, 2009 by telescoper

When I was writing my recent  (typically verbose) post about chaos  on a rainy saturday afternoon, I cut out a bit about astronomy because I thought it was too long even by my standards of prolixity. However, walking home this evening I realised I could actually use it in a new post inspired by a nice email I got after my Herschel lecture in Bath. More of that in a minute, but first the couple of paras I edited from the chaos item…

Astronomy provides a nice example that illustrates how easy it is to make things too complicated to solve. Suppose we have two massive bodies orbiting in otherwise empty space. They could be the Earth and Moon, for example, or a binary star system. Each of the bodies exerts a gravitational force on the other that causes it to move. Newton himself showed that the orbit followed by each of the bodies is an ellipse, and that both bodies orbit around their common centre of mass. The Earth is much more massive than the Moon, so the centre of mass of the Earth-Moon system is rather close to the centre of the Earth. Although the Moon appears to do all the moving, the Earth orbits too. If the two bodies have equal masses, they each orbit the mid-point of the line connecting them, like two dancers doing a waltz.

Now let us add one more body to the dance. It doesn’t seem like too drastic a complication to do this, but the result is a mathematical disaster. In fact there is no known mathematical solution for the gravitational three-body problem, apart from a few special cases where some simplifying symmetry helps us out. The same applies to the N-body problem for any N bigger than 2. We cannot solve the equations for systems of gravitating particles except by using numerical techniques and very big computers. We can do this very well these days, however, because computer power is cheap.

Computational cosmologists can “solve” the N-body problem for billions of particles, by starting with an input list of positions and velocities of all the particles. From this list the forces on each of them due to all the other particles can be calculated. Each particle is then moved a little according to Newton’s laws, thus advancing the system by one time-step. Then the forces are all calculated again and the system inches forward in time. At the end of the calculation, the solution obtained is simply a list of the positions and velocities of each of the particles. If you would like to know what would have happened with a slightly different set of initial conditions you need to run the entire calculation again. There is no elegant formula that can be applied for any input: each laborious calculation is specific to its initial conditions.

Now back to the Herschel lecture I gave, called The Cosmic Web, the name given to the frothy texture of the large-scale structure of the Universe revealed by galaxy surveys such as the 2dFGRS:

One of the points I tried to get across in the lecture was that we can explain the pattern – quite accurately – in the framework of the Big Bang cosmology by a process known as gravitational instability. Small initial irregularities in the density of the Universe tend to get amplified as time goes on. Regions just a bit denser than average tend to pull in material from their surroundings faster, getting denser and denser until they collapse in on themselves, thus forming bound objects.

This  Jeans instability  is the dominant mechanism behind star formation in molecular clouds, and it leads to the rapid collapse of blobby extended structures  to tightly bound clumps. On larger scales relevant to cosmological structure formation we have to take account of the fact that the universe is expanding. This means that gravity has to fight against the expansion in order to form structures, which slows it down. In the case of a static gas cloud the instability grows exponentially with time, whereas in an expanding background it is a slow power-law.

This actually helps us in cosmology because the process of structure formation is not so fast that it destroys all memory of the initial conditions, which is what happens when stars form. When we look at the large-scale structure of the galaxy distribution we are therefore seeing something which contains a memory of where it came from. I’ve blogged before about what started the whole thing off here.

Here’s a (very low-budget) animation of the formation of structure in the expanding universe as computed by an N-body code. The only subtlety in this is that it is in comoving coordinates, which expand with the universe: the box should really be getting bigger but is continually rescaled with the expansion to keep it the same size on the screen.

You can see that filaments form in profusion but these merge and disrupt in such a way that the characteristic size of the pattern evolves with time. This is called hierarchical clustering.

One of the questions I got by email after the talk was basically that if the same gravitational instability produced stars and large-scale structure, why wasn’t the whole universe just made of enormous star-like structures rather than all these strange filaments and things?

Part of the explanation is that the filaments are relatively transient things. The dominant picture is one in which the filaments and clusters
become incorporated in larger-scale structures but really dense concentrations, such as the spiral galaxies, which do
indeed look a bit like big solar systems, are relatively slow to form.

When a non-expanding cloud of gas collapses to form a star there is also some transient filamentary structure  but the processes involved go so rapidly that it is all swept away quickly. Out there in the expanding universe we can still see the cobwebs.
