R.I.P Dietrich Fischer-Dieskau

Posted in Music with tags , , , on May 19, 2012 by telescoper

I was very sad to hear, first thing this morning, of the death at the age of 86 of legendary singer Dietrich Fischer-Dieskau. I can’t add anything to the host of tributes that have already appeared, except to say that his voice will always be very special to me because his recording of Schubert’s Winterreise (with Gerald Moore on piano) was the first I ever heard of any Schubert Lieder.

Instead of trying to write an appreciation which couldn’t possibly to justice to the man and his musical legacy, I’ll just post this video and let it speak for itself. This is Winterreise in its entirety, performed in 1979 by Fischer-Dieskau with Alfred Brendel on piano.

Rest in peace, Dietrich Fischer-Dieskau (1925-2012).

Olympic Scale Disruption

Posted in Bute Park with tags , , , on May 18, 2012 by telescoper

Apparently the Torch is passing through Cardiff on 25th May 2012 ahead of the 2012 London Olympics. Some sort of celebration is going to happen in Bute Park that evening, and the preparations started earlier this week. Yet more heavy vehicle movements. Yet more temporary buildings. Yet more damage Cooper’s Fields (which will probably never be repaired). Yet more denial of public access to a public Park.

Any why on Earth does such a huge area have to be sealed off for two whole weeks just to make way for an event that will only last a few hours? What a waste of time! And I dread to think how much it’s going to cost…

The Moving Finger writes; and, having writ,
Moves on: nor all thy Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all thy Tears wash out a Word of it.

My private IDAHO

Posted in Uncategorized with tags , , , on May 17, 2012 by telescoper

Today, 17th May, is International day Against Homophobia and Transphobia (IDAHO). There are events going on all round the world, including the UK (for which you can find a list here).

As an oldie, I find it quite amazing how much attitudes have changed in the general population, and even within the police force, but sadly that doesn’t mean that homophobic hate crimes no longer happen. In fact, they are still depressingly commonplace. The path that leads to violence (and even murder) starts with verbal abuse, and this will only stop when all fair-minded people (straight, gay, bisexual, transexual and undecided) are prepared to confront the bigots. Maybe one day IDAHO will not be needed, but that day remains a long way off.

Here is the official IDAHO video

And here is a special message from these parts made by Stonewall Cymru and the Welsh Assembly

Driving Test

Posted in Cute Problems with tags on May 16, 2012 by telescoper

I’m currently stuck in the office while my third year students are tackling an exam I set. I have to wait by the telephone in case there’s a problem with the paper that I have to sort out.

As a quick diversion I thought I’d give my blog readers a little test of their own. Try this little poser:

EPSRC Blues

Posted in Science Politics with tags , , , , , on May 15, 2012 by telescoper

I woke up this morning to find via Twitter an interesting blog post about a demonstration in London against the policies of the Engineering and Physical Sciences Research Council (EPSRC).

For those of you not up with the ins and outs of the UK science funding regime, EPSRC is the agency that funds the more mainstream areas of physics (as well as chemistry, engineering and some mathematics) while the more exotic bits (particle physics, nuclear physics and astronomy) are the responsibility of the Science and Technology Facilities Council (STFC). The current protest seems to be lead by a number of eminent chemists, including Prof. Sir Harry Kroto, Prof. Sir John Cadogan and Prof. Anthony Barrett.

Almost five years ago – was it really so long? – owing to a mixture of funding cuts and incompetent management, STFC was born into a financial crisis that made many of us doing astronomy and particle physics wish that we also were protected by the friendly hands of EPSRC rather than left out in the cold as we felt we were at STFC. Things have slowly improved at STFC, which now has an executive team that actually seems to listen to its community as well as speaking the language that Whitehall wants to hear. Funding is still tight, but STFC is a noticeably happier ship now than it was it first launched.

In the meantime, any envy we might have had about our colleagues in, e.g., condensed matter physics being safer in the EPSRC stable has now well and truly evaporated. Their strategy, “Shaping Capability“, expressed in dreadful management-speak, involves the imposition of arbitrary priorities such as the restriction of fellowship applications to certain areas chosen by The Management. Worse, its new funding rules attempt to target funding at commercially-driven research. Dark clouds are gathering in the “blue skies” under which UK science has hitherto flourished.

The unresponsive top-down character of EPSRC has strengthened under the leadership of David Delpy who must have been made in the same factory as Keith Mason, former Chief Executive of STFC, whose diplomatic skills were similarly remarkable by their absence.

For some reason, this reminds me of the following quote from Smiley’s People

In my time, Peter Guillam, I’ve seen Whitehall skirts go up and come down again. I’ve listened to all the excellent argument for doing nothing, and reaped the consequent frightful harvest. I’ve watched people hop up and down and call it progress. I’ve seen good men go to the wall and the idiots get promoted with a dazzling regularity.

I’ve argued before that I think EPSRC’s approach is fundamentally wrong. When taxpayers’ money used is used to generate immediate commercial returns, it ends up in the pockets of entrepreneurs when the research succeeds and, if it doesn’t, the grant has effectively been wasted. Commercial Impact should not be a factor in awarding public funding, because it is perfectly suited as a criterion for attracting private funding. This is why we have a national fiscal policy: the only justification for levying taxation is to fund projects which will not yield short-term economic returns. There is no reason to spend public money on commercial projects: we need to justify pure research by a non-economic valuation.

This morning EPSRC have issued a press release calling upon scientists to work together ahead of the forthcoming comprehensive spending review. It doesn’t mention the demonstration, or other manifestations of unrest within the EPSRC community, but instead re-asserts the need for its so-called strategy, with a clear message not to rock the boat ahead of the next Comprehensive Spending Review.

I’ve heard that argument many times in the context of STFC during its crisis period. I firmly believe that rocking the boat in that case helped it get off the rocks. It remains to be seen whether the EPSRC protest, which is currently rather small, will gather enough momentum to make a difference. It all depends on what fraction of EPSRC scientists have actually signed up to the Delpy Agenda. Is the new campaign representative of the views of the EPSRC community? No doubt many research groups will be prospering under the new regime, at least in the short term. Time alone will tell what the long-term impact of short-termism will be.

Rigid Body Sings

Posted in Poetry, The Universe and Stuff with tags , , , , on May 14, 2012 by telescoper

Gin a body meet a body
Flyin’ thro the air,
Gin a body hit a body,
Will it fly? And where?

Ilka impact has its measure
Ne’er a’ ane hae I
Yet a’ the lads they measure me,
Or, at least, they try.

Gin a body meet a body
Altogether free,
How they travel afterwards
We do not always see.

Ilka problem has its method
By analytics high;
For me, I ken na ane o’ them,
But what the waur am I?

by James Clerk Maxwell (1831-1879)

P.S. This poet is of course much better known as a physicist, but this is a nice little parody of Robert Burns’ Comin’ through the Rye in authentic Scots.

Bayes’ Theorem and the Search for Supersymmetry

Posted in The Universe and Stuff with tags , , , , on May 13, 2012 by telescoper

Interesting comments about Bayes’ theorem and the prospects for detecting supersymmetry at the Large Hadron Collider. This piece explains how a non-detection isn’t always “absence of evidence” but can indeed by “evidence of absence”. It’s also worth reading the comments if you’re wondering whether what people say about Lubos Motl is actually true…

Phi G's avatarviXra log

Here’s a puzzle. There are three cups upside down on a table. You friend tells you that a pea is hidden under one of them. Based on past experience you estimate that there is a 90% probability that this is true. You turn over two cups and don’t find the pea. What is the probability now that there is a pea underneath? You may want to think about this before reading on.

Naively you might think that two-thirds of the parameter space has been eliminated, so the probability has gone from 90% to 30%, but this is quite wrong. You can use Bayes Theorem to get the correct answer but let me give you a more intuitive frequentist answer. The situation can be models by imagining that there are thirty initial possibilities with equal probability. Nine of them have a pea under the first cup, nine more under the second and nine more under the third…

Crossword Look-alikes

Posted in Crosswords with tags , , , on May 13, 2012 by telescoper

I wonder if anyone else has noticed the remarkable similarity between this clue, by Paul, in yesterdays Guardian Prize Crossword (No. 25634)

Foolishly cash lost in ’em? (4,8)

and this one in Everyman No. 3423 which appeared in today’s Observer:

One-armed bandits – lost cash in ’em, stupidly (4,8)

I wonder if, by any chance, they might be related?

More interestingly, the clue by Paul is a nice example of an “&lit” clue whereas the Everyman one has the traditional definition + cryptic parts. In an &lit clue two different readings of the clue give the definition and cryptic allusion. In this one the word “foolishly” is an anagram indicator (acting on the subsequent  letters); the surface reading (“literally what it says”) defines something you might lose money in foolishly. This kind of clue often ends with a “?” or even a “!” to suggest something a bit sneaky is going on so a bit more lateral thinking than usual may be required.  The second clue has the same anagram (indicated by “stupidly”) but this is preceded by a straightforward definition of the answer so has no “?” at the end.

I’m not going to give the answer, but it’s quite an easy one so I assume the penny has dropped.

The Train and the River

Posted in Biographical, Books, Talks and Reviews with tags , , , on May 12, 2012 by telescoper

Well, here I am back in Cardiff after my little trip to Merseyside. The weather behaved itself and so did the trains in both directions, so it was quite a pleasant travelling experience. In fact, going there yesterday I managed to make a technically impossible connection at Crewe, owing to the train from Cardiff being a minute or two early and the train to Liverpool being a minute late.

I stayed last night at the Jury’s Inn at Albert Dock, shown on the left here. There’s a sort of Ferris Wheel thing next to it. These contraptions seem to be popping up all over the place. Next thing you know there’ll be one in London! The hotel was of its type, generic but reasonably comfortable. Brings back memories of STFC panel meeting; the Jury’s Inn there is a standard place to stay in Swindon when sentenced to hard labour. Unfortunately the one I stayed in was booked up by multiple stag and hen parties and was ridiculously noisy all night. I didn’t really get any sleep until well after 4am. Grump.

Anyway, last night we had a very nice dinner at the Clove Hitch restaurant/bistro (which I definitely recommend) preceded by a pint at the famous Philharmonic Pub. Thanks to Phil and Sue for looking after us so nicely.

My talk opened the proceedings at the Merseyside Astronomy Day, which was held at Spaceport on the Birkenhead side of the Mersey. Here’s a view of Liverpool’s impressive skyline taken from there, with a nice sailing barge on the Mersey.

The small auditorium – usually used for Planetarium shows – was pretty full and I think my talk went quite well, although it’s not really for me to say. They did actually record everything so if I can get hold of a copy I might post it. Anyway, after my turn there was a fascinating lecture by Prof. Peter Read of Oxford University about the atmospheres of Jupiter and Saturn.

After a quick lunch we used Liverpool’s excellent public transport to zip back to Liverpool Lime Street and I had a relaxing and punctual journey back to Cardiff, albeit with no miracle change at Crewe this time. Dozing on the train I quite startled to wake up near Shrewsbury to find a vintage steam locomotive in sight:

No doubt there’ll be someone out there in internetshire who will tell me all about this train through the comments box but for now I’m going to make some dinner and take it easy as I’m rather knackered.
