Although it’s meant to be a holiday I’ve actually been in the department most of the day working on some research (or, rather, writing up some old research). Since I’ve been tapping away at the keys most of the day I haven’t got the energy to write much, and I’m looking forward to a drink and a spot of curry in a few minutes’ time followed by a crack at the jumbo-sized Guardian Easter crossword compiled  by my favourite setter, Araucaria.

However, for the purposes of my own record-keeping – this blog is, at least in part, some kind of a journal – I thought I’d make a quick note of the day’s sport. Usually as we near the end of the football season I get into a state of nervous anxiety wondering what sort of mess my own team, Newcastle United, are going to make of the run-in. However, today I’m pleased to say they followed up Monday’s win against Nottingham Forest with another victory, 3-2 away at Peterborough. Although their opponents are the bottom club of the division at the moment, I always thought this would be a tricky game and so it proved if the press reports are to be believed. Peterborough in fact took an early lead, and Newcastle didn’t equalise until stoppage time in the first half. They then went 3-1 up, only to have one goal pegged back by a determined home team.

That result might have sealed promotion to the Premiership for Newcastle, had Nottingham Forest done the decent thing and lost to Bristol City. They didn’t lose, but only managed a draw. The gap between Newcastle and Nottingham Forest is now 15 points with Forest having five games to play while Newcastle have six games left. It’s extremely improbable that Newcastle will lose all 6 of their games and Forest win all 5 of theirs, so I think we’re pretty much guaranteed to go up. We need just one point to turn that into mathematical certainty.

Today was a big game here in Cardiff too, between Cardiff City and fierce local rivals Swansea. Police helicopters were circling the town all day and there was a heavy presence of uniformed officers trying to ensure there wasn’t any trouble at the match. This too was a close-fought game. With the score at 1-1 until stoppage time at the end of the match, Michael Chopra popped up to score a winner for Cardiff. They’re now hard on the heels of Nottingham Forest in fourth place, with 68 points to Forest’s 71. Cardiff might still have to play Swansea in the playoffs. That could be interesting..

And finally, it’s worth noting that today was the day of the annual Oxford versus Cambridge Boat Race in London. I’m not going to pretend that I follow this sport particularly closely, but the occasions on which I’ve been to watch the spectacle have been very enjoyable (even though Oxford has beaten my own Alma Mater every time I’ve bothered to watch it). It’s usually more of an excuse to have a few drinks while watching other people busting a gut than a genuine interest in the sport. Still, I do have a residual loyalty to Cambridge University so I was delighted to find out that they won today. If I’d seen the pre-race odds, I might have had a bet as Oxford were clear favourites.

Not at all a bad day results-wise. I almost finished my paper too…

You’ve Got To Give Me Some..

Another quick break from writing gives me an excuse to post another favourite tune…

If you thought that raunchy lyrics were bound to be banned from records made 80 years ago, then just get a load of this.
It was recorded in 1928 by the greatest female blues singer of them all, Bessie Smith (“The Empress of the Blues”), together with Clarence Williams on piano and Eddie Lang on guitar. Bessie Smith was a notoriously loud and sometimes violent woman, who had an insatiable appetite for booze and sex (with, it’s said, both men and women). She also had a voice like no-one else on earth before or since.

 This is one of several very naughty records she made in the late twenties, others including “Do your duty” and “Take me for a buggy ride” but this is probably the rudest of the lot. I like the video too. Enjoy!

Now, anyone for round steak?

Othello Molineaux

Well, it’s a cold and rainy Good Friday holiday and I’ve got a stack of work to catch up on. Before I resume after my coffee break, however, I thought I’d share this little bit of Caribbean sunshine with you.

 I first came across the name of Othello Molineaux about 30 years ago on a record he made with Monty Alexander, and was completely blown away by his virtuosity on the steel drum,  an instrument I thought was very limited until I heard him play it! Here he is demonstrating his astonishing skill and musical imagination at a live concert recorded only last year. It’s great to see he’s still going strong 30 years after I first heard his music!

About a month ago, a typically rambling blog post of mine led to a discussion of the use of unusual instruments in jazz. This would have fit nicely into that thread if I’d remembered it at the time! Better late than never. Remember that if you enjoy this half as much as I do, then I enjoyed it twice as much as you..

The Stitch-up Continues…

Posted in Science Politics with tags , , , , on April 1, 2010 by telescoper

Interesting news from the Science and Technology Facilities Council (STFC). Following the retirement of Professor Mike Edmonds from his post of Professor of Astronomy at Cardiff University – enabling yours truly to take his office! – he decided to resign his position on STFC Council. Yesterday, STFC announced that he would be replaced on its highest-level governing body, not with one person but with three, taking the membership of the Council to 12.

The new trio consists of  Mr Will Whitehorn (President of Virgin Galactic), Dr Michael Healy (President of the navigation business division of Astrium), and Mrs Gill Ball (Finance Director at the University of Birmingham). Given the catastrophic shambles of STFC’s current financial situation, the last appointment seems to make good sense. On the other hand, what on Earth is going on with the first two?

The new UK Space Agency came into existence today, 1st April 2010 – no joke. This is supposed to take overall control of all our national space activity, including commercial ventures as well as those parts (such as the subscription to the European Space Agency and funding for space instrumentation) previously under the control of STFC. Since space has now been hived off into another organisation altogether, why does  STFC now have  two commercial space gurus added to its Council?  The only explanation I can think of is that the STFC Executive is going to focus even further on space exploration rather than on basic research. These appointments were made by the Science Minister, Lord Drayson, who was the driving force behind the creation of the new UK Space Agency and they strongly suggest that he wants the emphasis within STFC to move in the direction of space exploration, to the likely detriment of the rest of science.  The implications for the future of observational astronomy and particle physics are deeply worrying.

Even more worryingly for those of us involved in basic research, note that one of the few scientists on Council has been replaced by three people whose interests lie elsewhere. In fact the number of independent scientists on Council has thus been reduced from 5 to 4. You can draw your own conclusions about what this means for the future of pure science in the rump of STFC…

Other interesting news this week is that the government has conjured up £100 million for the Diamond Light Source. I don’t want for one moment to give the impression that in the slightest bit negative about this facility or the new investment in it. It is immensely valuable for research across a  wide spectrum of scientific disciplines, and I was very glad to hear of the new investment. The extra funds will enable it to increase the number of beamlines from 10 to 32 which will represent a huge increase in its productivity.

But, while the cash injection for the Diamond Light Source is clearly to be applauded, it does provide a contrast with other areas within STFC’s remit  whose research budgets have been pared to the bone. In the last grant round, for example, one-third of all the astronomy rolling grants (6 out of 18)  up for renewal this year have been axed, and the others cut back severely. All the evidence suggests that there is no interest in reversing  the cuts in the STFC management, and that they will actually get very much worse over the next few years.

Since STFC blundered into financial meltdown in 2007, there have been two main theories as to what happened; remember that this was before the Credit Crunch took hold, so the black hole in STFC’s initial budget was nothing to do with the subsequent recession. One was that the STFC Management made a mess of their submission to the Comprehensive Spending Review and that it was all down to ineptitude. The other theory is that there was a definite plan at a high political level – probably in the Treasury – to rein back expenditure on fundamental research in favour of more “applied” disciplines. The shortfall in STFC’s finances was thus manufactured to achieve precisely what it has achieved. Depending on which of these theories you believe (if either), then the STFC Chief Executive is cast either as a bumbling incompetent or as a willing stooge of the Whitehall mandarins (although to be fair the two are not mutually exclusive).  The more the sorry saga of STFC pans out, the more I believe it was all a deliberate stitch-up. I think the most recent developments corroborate my view in depressingly convincing fashion.

STFC came into the world in 2007 with an estimated budget shortfall of £80 million. Had the £100 million I mentioned above appeared sooner, and had it gone into STFC’s general budget rather than being, as it is, ring-fenced for the Diamond Light Source then the carnage inflicted on science research could have been avoided. Instead, STFC squeezed its research grant line until the pips squeaked. Now that they’ve done this job, and got away with relatively little organized opposition from the scientific community, suddenly the money appears. It looks to me like the budget deficit was engineered to achieve precisely the outcome that has occurred.

I predict that after the election, the STFC budget will be slashed once more and that astronomy and particle physics research will again bear the brunt as STFC increasingly focusses on space exploration. The exodus of talented scientists from Britain that has already started and is sure to accelerate over the next year or two will take decades to reverse. It’s time for those responsible to come clean.

Tremblin’ Blues

Posted in Jazz with tags , , on March 31, 2010 by telescoper

I just noticed that a few days ago someone posted this lovely old blues on Youtube. It’s by one of my all-time favourite blues piano players, Little Brother Montgomery, who died in 1985 aged 79. He was self-taught (as many of the great jazz and blues musicians were) and was such a quick learner that he was playing professionally by the time he was 11.

He toured the UK and Europe quite regularly in the  1960s and made many recordings here, including some wonderfully relaxed music recorded at the Sussex home of eccentric jazz enthusiast Francis Wilford Smith, a  marvellous old character who passed away a few months ago in 2009. I mention this because I have an old LP that features Tremblin’ Blues by Little Brother Montgomery, recorded on the Magpie label. That one is much slower than the one here and is punctuated by chuckles from the pianist, suggesting that he might have been just a little bit inebriated at the time. This one’s a bit crisper, free of giggles, but still a lovely performance.

Apologies to Professor Brian Cox, but I couldn’t resist this! I think it’s hilarious…

A word of warning: it contains colourful language, so please be sure to watch it after the watershed. And if you can’t find water, lava will do just as well.

The Thieving Magpie

Posted in Football, Opera with tags , , , on March 30, 2010 by telescoper

Well, I’ve spent the evening working as well as following an important night’s football. My team – Newcastle United – were playing their promotion rivals Nottingham Forest at St James’ Park (in Newcastle). Going into the game Newcastle were at the top of the Championship, 10 points clear of third-placed Nottingham Forest with a game in hand. With 80 points from 38 games, and only 8 remaining to play, a win would virtually guarantee that Forest (on 70 points after 39 games) couldn’t catch them and Newcastle would therefore be in one of the top two positions guaranteeing them a return to the Premiership next season.

Although this was apparently a commanding position, I’ve been a Newcastle supporter for too long to take anything for granted; they’ve demonstrated their ability to throw away apparently unassailable leads far too often for me to feel complacent. Fortunately, they didn’t let me down. Two second-half goals (from Shola Ameobi and Jose Enrique) saw them win 2-0. Now 13 points clear of third place (with Forest only having 6 games to play), they are on the brink of automatic promotion. Mathematically they now need 6 points from 7 games to be sure, but they could seal it on Saturday away against bottom club Peterborough, if Nottingham Forest lose against Bristol City.

I confess that I get badly affected by nerves when following games on the radio or TV. I’d much rather be there in the flesh, but sadly that’s impractical. When the final whistle went tonight I was enormously relieved and more than a little bit elated, despite the heavy cold I’ve got at the moment.

Anyway, I thought it called for a bit of musical celebration. Newcastle United’s nickname is The Magpies, so I thought I’d offer the overture from Gioachino Rossini‘s Opera La Gazza Ladra (The Thieving Magpie).  It’s not the greatest opera, but the overture is superb. Apparently Rossini had to be locked in his room and forced to write it as the deadline for the first performance approached. If that’s true, the pressure had a positive effect on him because what he produced is a cracker.

This performance is tremendously virtuosic – as you’d expect from the Vienna Philharmonic – especially in the accelerando part at the end, which is wonderfully exhilirating.

I’ve only known a few professional classical musicians at a personal level, but all of them, when asked, said that the composer whose music they most enjoyed playing was Rossini. I was always surprised to hear that, but listening to this piece I can certainly understand them. It’s got to be great fun playing this…

P.S. Another thing worth mentioning is that the current owner of Newcastle United Football Club bears more than a passing resemblance to Rossini!

My Friend Erdös..

Posted in Biographical with tags , , , , , , on March 28, 2010 by telescoper

After one of my  lectures a few weeks ago, a student came up to me and asked whether I had an Erdős number and, if so, what it was.  I didn’t actually know what he was talking about but was yesterday reminded of it, so tried to find out.

In case you didn’t know, Paul Erdős (who died in 1996) was an eccentric Hungarian mathematician who wrote more than 1000 mathematical papers during his life but never settled in one place for any length of time. He travelled between colleagues and conference, mostly living out of a suitcase, and showed no interest at all in property or possessions. His story is a fascinating one, and his contributions to mathematics were immense and wide-ranging.  The Erdős number is a tiny part of his legacy, but one that seems to have taken hold. Some mathematicians appear to take it very seriously, but most treat it with tongue firmly in cheek, as I certainly do.

So what is the Erdős number?

It’s actually quite simple to define. First, Erdős himself is assigned an Erdős number of zero. Anyone who co-authored a paper with Erdős has an Erdős number of 1. Then anyone who wrote a paper with someone who wrote a paper with Erdős has an Erdős number of 2, and so on. The Erdős number is thus a measure of “collaborative distance”, with lower numbers representing closer connections.

I say it’s quite easy to define, but it’s rather harder to calculate. Or it would be were it not for modern bibliographic databases. In fact there’s a website run by the American Mathematical Society which allows you to calculate your Erdős number as well as a similar measure of collaborative distance with respect to any other mathematician.

A list of individuals with very low Erdős numbers (1, 2 or 3) can be found here.

Given that Erdős was basically a pure mathematician, I didn’t expect first to show up as having any Erdős number at all, since I’m not really a mathematician and I’m certainly not very pure. However, his influence is clearly felt very strongly in  physics and a surprisingly large number of physicists (and astronomers) have a surprisingly small Erdős number. According to the AMS website, mine is 5 – much lower than I would have expected. The path from me to Erdős in this case goes through G.F.R. Ellis, a renowned expert in the mathematics of general relativity (as well as a ridiculous number of other things!). I wrote a paper and a book with George Ellis some time ago.

However, looking at the list I realise that I have another route to Erdős, through the great Russian mathematician Vladimir Arnold, who has an Erdős number of 3. Arnold wrote a paper with Sergei Shandarin with whom I wrote a paper some time ago. That gives me another route to an Erdős number of 5, but I can’t find any paths  shorter than that.

I guess many researchers will have links through their PhD supervisors, so I checked mine – John D. Barrow. It turns out he also has an Erdős number of 5 so a path through him doesn’t lower my number.

I used to work in the School of Mathematical Sciences at Queen Mary, University of London, and it is there that I found some people I know well who have lower Erdős numbers than me. Reza Tavakol, for example, has an Erdős number of 3 but although I’ve known him for 20 years, we’ve never written a paper together. If we did, I could reduce my Erdős number by one. You never know….

This means that anyone I’ve ever written a paper with has an Erdős number no greater than 6. I doubt if it’s very important, but it definitely qualifies as Quite Interesting.

Alternative Logo for UKSA

Posted in Science Politics with tags on March 27, 2010 by telescoper

As you all know, this past week saw the launch of the new UK Space Agency amid much fuss and fanfares. This occasion allowed the government to trumpet the creation of the new organization as a success story in the media and thus draw attention away from the continuing devastation visited on scientific research in astronomy and space science in the United Kingdom.

I’m not the only one to have expressed reservations about the quality of the new outfit’s logo which, though clearly intended to present a thrusting, dynamic, reach-for-the-skies image, ends up looking more like something from Dad’s Army. Apparently it cost £10,000 – surprisingly cheap by the standards of graphic designers these days – which perhaps explains why it isn’t very good, although even expensive ones can be rubbish too.

In order to improve the public profile of the fledgling organisation, and out of my own deep sense of public spiritedness, I’ve decided, at no expense to the taxpayer, to commission my own alternative logo by a highly skilled graphic designer of my acquaintance. I’m proud to be able to unveil it here. I think it conveys more accurately the nature of the new agency.

The broad coloured swathe represents the red tape involved in creating yet another new quango and reorganising everything else that relates to it. This leads initially to a period of increased paperwork presenting the appearance of greater activity until, shortly after the next election, everyone realises it is achieving nothing at all, its funds are cut (along with everything else), and, overwhelmed by the weight of its own bureaucracy,  it comes crashing back to Earth.

Badges featuring the new logo can be purchased from me, at the modest price of £74.99 each.
