Class of ’11

Posted in Biographical, Education with tags , , on July 19, 2011 by telescoper

Just a quick note to mark today’s graduation ceremony for students in the School of Physics & Astronomy at Cardiff University, which took place at 10 o’clock this morning in St David’s Hall. I took part in the staff procession this year – as I have done on several previous occasions – so was there bright and early, all togged up in academic drag, ready for the kick-off. You can see a replay of the whole thing here so I don’t need to describe it in detail; I’m seated towards the left hand side of the stage so am fortunately out of shot for most of the video.

I admit to having had a bit of a hangover this morning because yesterday evening I attended a posh (black tie) graduation dinner at the invitation of the Vice-Chancellor. The splendid dinner was preceded by a drinks reception that lasted a full hour – at which much champagne was quaffed – and then followed by some lengthy and rather uninspiring speeches, during which I sought solace in the form of port. When proceedings were over, a few of us decanted ourselves into a local bar for a bit more to drink. I only realised how much I must have drunk when Columbo woke me up by jumping on my bed at 5am at which point I felt distinctly sub-optimal.

After the graduation ceremony there was a reception for graduates, parents, partners and assorted hangers-on back at the School of Physics & Astronomy followed by the obligatory pictures with the Head of School, Walter Gear, and Director of Undergraduate Studies, Bernard Richardson, including several attempts at the old “mortar-boards-in-the-air” shot…

..of which my attempt with a phone camera came out surprisingly well!

The MPhys students graduating this year are the first such group that I’ve seen go all the way from first year to graduation, as I moved to Cardiff University in 2007.  Graduation is always a bittersweet occasion, with joy  at the students’ success, but also sadness that we have to say goodbye.   Some will be staying to do PhDs and some will remain in Cardiff for a host of other reasons, but there’s a  number of students in this group that I will miss a lot.

 

People vs projects in science funding (via Responsible Innovation)

Posted in Finance, Science Politics with tags , on July 19, 2011 by telescoper

Interesting article about whether funding should go to scientists with reputations, or to excellent projects…

Prompted by a question from Times science correspondent Hannah Devlin on Twitter, some thoughts on whether science funders should concentrate on funding people or funding projects… There appears to be growing interest in the idea of channeling funding through individuals. In the last few years, we’ve seen the Wellcome Trust redirect money towards people. EPSRC and other research councils are interested too. Paul Nurse and other senior scientist … Read More

The force that through the green fuse drives the flower

Posted in Poetry with tags on July 19, 2011 by telescoper

The force that through the green fuse drives the flower
Drives my green age; that blasts the roots of trees
Is my destroyer.
And I am dumb to tell the crooked rose
My youth is bent by the same wintry fever.

The force that drives the water through the rocks
Drives my red blood; that dries the mouthing streams
Turns mine to wax.
And I am dumb to mouth unto my veins
How at the mountain spring the same mouth sucks.

The hand that whirls the water in the pool
Stirs the quicksand; that ropes the blowing wind
Hauls my shroud sail.
And I am dumb to tell the hanging man
How of my clay is made the hangman’s lime.

The lips of time leech to the fountain head;
Love drips and gathers, but the fallen blood
Shall calm her sores.
And I am dumb to tell a weather’s wind
How time has ticked a heaven round the stars.

And I am dumb to tell the lover’s tomb
How at my sheet goes the same crooked worm.

by Dylan Thomas (1914-1953)

P.S. This has been among my list of poems to post for some time now, and only today I find that cosmic variance have beaten me to it!

 

Top Tips

Posted in Uncategorized with tags , on July 18, 2011 by telescoper

Not a lot of people know that one of my first publications was a contribution to the Top Tips section of the esteemed Viz Comic, which originates from my home town of Newcastle upon Tyne. The aforementioned Top Tips offer absurd, impractical or ludicrous suggestions to parody those in “lifestytle”  magazines proposing handy hints to make domestic and everyday life easier.

I’ve been tweeting a few of my favourites over the last few days, including a couple of (very) vaguely astronomical ones, so I thought I’d collect some of them here. The first is relevant to this week’s festivities:

  • Avoid feeling uncomfortably hot during your graduation ceremony by wearing only underwear underneath your gown
  • A ‘guide bat’ tethered to your finger with a short piece of string is the perfect way to avoid trees and horses in the dark.
  • Prevent your shoes from giving you blisters by lining their insides with sticking plasters
  • Astronomers avoid total blindness when viewing the sun  by using a telescope rather than binoculars
  • Reduce the risk of night-time fires by soaking all your furniture with a hosepipe before going to bed
  • Make your own inexpensive mints by leaving blobs of toothpaste to dry on a window sill
  • A used condom filled with water and left on a radiator makes an attractive yet inexpensive lava lamp
  • Avoid the need for expensive binoculars by simply standing cl0ser to the object that you wish to view
  • Avoid hiring unlucky people by immediately tossing half the CVs into the bin
  • Sausage rolls sewn together side by side make an excellent emergency wig for judges
  • Dabs of silver model aircraft paint can transform  repulsive facial warts into fashionable piercings

Feel free to add your own contributions- preferably original and, even better, with a physics or astronomy theme – through the medium of the comments box…

From Major to Minor

Posted in Music with tags , , , , , , on July 17, 2011 by telescoper

I was looking around for something to post next week in honour of our graduation ceremony (which is coming up on Tuesday) and came across this, which brought back a flood of memories. It’s the wonderful Annie Lennox singing the classic Cole Porter song Ev’ry Time We Say Goodbye as performed as part of the AIDS fund-raiser Red Hot and Blue way back in 1990. Was it really that long ago?

Cole Porter has to be  one of the cleverest songwriters of all time.  His ability to produce tune after lovely tune was matched by his supreme skill in crafting the lyrics, often managing to produce rhymes in the middle of lines as well as at the end. He often used this superb craftsmanship to comic effect, but produced his share of beautiful ballads too, though none more beautiful than this. I’ve always loved the Ella Fitzgerald version of this song so much that I didn’t believe anyone could outdo it, but this track (and the video) moved me to tears when I first saw it, and it’s never lost its impact on me, especially when heard with the poignant video. The  little  boy shown in the home movies is a young  Derek Jarman, who died of an AIDS-related illness in 1994.

This song exemplifies Cole Porter’s art as both  composer and wordsmith. The trademark clever rhymes are there, but in this case there’s a wonderful juxtaposition of  the words “how strange the change from major to minor” and an interesting chord progression, which is a minor scale variation of the plagal cadence (sometimes called the “Amen cadence”, because it’s how the word A-men is often sung in hymns). The plagal cadence involves a IV-I step back to the tonic chord (I), via a major 4th (IV) but in Ev’ry Time We Say Goodbye, the progression goes via   IV-iv-I with the interpolation of a minor 4th chord (iv), which in the original key of E♭is an A♭m chord. It’s a lovely touch, no less lovely for being so clever.

This progression – or a variation of it involving a dominant 7th chord (i.e. IV-iv-♭VII-I) –  can be found in many jazz standards, as  a kind of “bluesy” alternative to the more usual V-I “authentic” cadence, and many pop songs use it too, including several by The Beatles.  However, I doubt if even Cole Porter could have come up with a rhyme for “dominant seventh”!

Some of you might think this is just ridiculous hype, but I couldn’t possibly comment…

Hold your breath I don’t think there has ever been a moment quite like this in physics before. Within the next few months, weeks or even days we will learn something new about the universe that will change our thinking forever. I don’t mean something like a little CP asymmetry or a new observation of neutrino physics. These things are great but they just pose questions that we can’t answer yet. What we are about to learn is going to generate so many new ideas in … Read More

Dissembling Nature

Posted in Uncategorized with tags , , , , , on July 16, 2011 by telescoper

Interesting that the Journal Nature is introducing a registration wall for its News pages. These pages have previously been free and, we’re told, will remain so. However, in order to access them one will now have to give a name and email address.

I heard about this On Wednesday (13th July) on  Twitter (via @NatureNews):

OK, we’ve got some news that may annoy: @NatureNews is going to start requiring registration to view some of our free news stories. (1/2)

Don’t panic! All the news is still free. We’re just going to ask for a name and an email. (2/2)

(For those of you not among the Twitterati I should point out that messages on Twitter have to be less than 140 characters long, hence the use of two tweets in this case).

My immediate reaction – and that of manyof my colleagues – is that this looks very much like the strategy pursued by the Times online edition. First introduce registration, then shortly afterwards turn it into a paywall. In the meantime can collect all the email addresses in order to send marketing spam to those who have registered.

I inquired as to what they were planning to do with the email addresses they would be harvesting in this way, but didn’t get a satisfactory reply. Then I received a message from another branch of the Nature twitter operation, @npgnews:

@telescoper Hi Peter. Thanks for your comments. We’re about to send a series of tweets in response to Nature News registration.

Being a reserved British type I was a bit annoyed by the  “Hi Peter”  from someone I don’t know and have never spoken to before, but didn’t respond. Instead I waited with baited breath for the in-depth explanation of what Nature is going to do. Eventually it came, in three tweets:

Thx for your comments about the Nature News registration system. We’re asking all readers to introduce themselves by registering once (1/3)

Registration enables free access to the Nature News content, which remains unchanged. (2/3)

We’re working hard to expand and introduce more tailored services for readers and registration is necessary for that (3/3)

To say I found this disappointing would be an understatement. What a load of flannel. Note the word “enables” in Tweet No. 2. Free access was previously enabled to everyone, but is apparently to be disabled in order to facilitate the collection of user data for some unspecified purpose. Tweet No. 3 is a masterpiece of non sequitur. Why does expansion of Nature News require a database of email addresses? And what can “more tailored services” mean other than restricting access? Needless to say, I won’t be registering. There are other plenty of other sources of science information

Nature is of course a business operation, and you have to see this move against the wider backdrop of traditional publishing companies trying to find the way forward in the digital age. As a commercial enterprise, they are entitled to charge customers, although I wish they would be a little more honest about their intention to do so. I would remind them however, that The Times‘ paywall has been an unmitigated disaster, in terms of the negative an effect it has had on the readership figures. Given the revelations of the past weeks about the behaviour of News International, I bet people who were foolish enough to register are now wondering who has their personal information now. Will Nature News go the same way?

More importantly, however, as a scientist, I think that Nature’s policy of copyrighting and restricting general access to scientific papers is fundamentally wrong and is actively damaging science. I believe that scientific results should be in the public domain, as should the data on which they are based. Open access is the way it should be. In the past, publishers greatly assisted in the dissemination of research both between academics and to the public. Now, I’m afraid, the academic publishing industry is simply parasitic, and it is a threat to the health of scientific research. Fortunately, I don’t think a drastic remedy is needed; it will wither away on it’s own. Let’s just let Nature take its course.

 

The Perils of Modern Living

Posted in Poetry, The Universe and Stuff with tags , , , on July 15, 2011 by telescoper

Well up above the tropostrata
There is a region stark and stellar
Where, on a streak of anti-matter
Lived Dr. Edward Anti-Teller.

Remote from Fusion’s origin,
He lived unguessed and unawares
With all his antikith and kin,
And kept macassars on his chairs.

One morning, idling by the sea,
He spied a tin of monstrous girth
That bore three letters: A. E. C.
Out stepped a visitor from Earth.

Then, shouting gladly o’er the sands,
Met two who in their alien ways
Were like as lentils. Their right hands
Clasped, and the rest was gamma rays.

by Prof. Harold P. Furth (1930-2002)

A Diving Bell Problem

Posted in Cute Problems with tags , on July 14, 2011 by telescoper

You will have noticed that, in recent weeks, I’ve been posting divers physics problems on here. They seem to be quite popular so I thought I’d try another, which I found this morning in an old A-level physics textbook:

A diving bell of internal volume 6 m3 is lowered into a freshwater lake until the volume of the contained air is 4 m3. The height of a water barometer at the surface is 10 m. Assume that the temperature of the air in the bell does not change as the bell is lowered.
