Quantum Shock

I'm in the midsts of some new calculations right now as well as writing up a paper I've been working on for a few months, so no detailed blogging today. I did want to quickly add a little self-deprecating self-promotion if that isn't a complete oxymoron.

Having appeared on TV here in front of 200 million (I still haven't seen the broadcast, though that's probably a good thing) and now being the voice to unknown thousands or possibly millions of school kids wishing to learn British English I felt that it was about time to make an impact in print. Well, actually I didn't decide, but I was contacted by the editors of 'Beijing city weekender', firstly in relation to my photos and then once they found out I was a scientist, purely in relation to my life here.

BCW is a free biweekly publication, mostly for the English speaking expat community. Every issue they have a 'Day in the life of' article, where they see what people in various professions get up to in a normal working day. They hadn't had a scientist in before so asked if I was interested. This would involve me writing about an average day and coming in for a photo shoot.

The writing was fine, the photo shoot was very strange. The editor, a photographer and his assistant and I stood in the photo studio. I took a look around the place and eyed up the cameras. They also have a sister publication all about cooking and so I took a sneak peek in the well fitted-out kitchen where they create the dishes to photograph.

I was put on the spot, literally, as they started taking snaps. I stood there, looking slightly awkward having never had attention quite like this directed at me. I just stood in the most natural pose I could muster until they said:

'OK, you can, you know, do stuff now, you know, like poses'

'like what, sorry?'

'You know, make some poses'

I go between bouts of thinking myself reasonably confident and bouts of returning to the fact that I'm a gangly guy who was always pretty nervous at school. The call to 'make some poses' didn't help and I found myself standing there making perhaps the most unnatural poses they'd ever seen. They managed not to laugh and continued to shoot as I stood there feeling rather bewildered.

Well, they got their shots and then took some snaps of the three things from my day I had brought along: my laptop, a copy of Polchinski and my camera.

I headed off, bemused at what it would all turn out like. Well, I am bemused no longer (that's a lie, I spend most of my time in a state of slight bemusement), but for the purposes of this post I now know that they chose an only moderately awful pose (believe me, it could have been a lot worse!):

Welcome to the world of Quantum Shock (Note that they didn't go for the obvious Doc Shock jokes):

Strings '07

Strings 2007 starts today in Madrid. The videos from the week of talks on the year's progress should be available online, linked from this page.

It was pointed out last year the importance of keeping close connections between the experimental community so that those working in the many interesting but often deeply theoretical aspects of string theory do not lose sight of the ultimate goal of science.
The first talk this year is on 'Status and prospects of the LHC machine and experiments'. (Schedule here).

With some interesting and appropriate timing Witten has today released his long awaited paper on three dimensional gravity. I look forward to watching this talk in particular but the others which are of particular interest to me are Beisert on 'strong/weak interpolation in the spectrum of AdS/CFT', Kallosh on 'testing string theory with the CMB', Bern on 'the UV finiteness of N=8 SUGRA' and Sugimoto on 'baryons from instantons in holographic QCD', though there's lots more of interest besides.

Besides Witten's paper today there is the pre-print 'Quark Mass in the Sakai-Sugimoto Model of Chiral Symmetry Breaking' From Evans and Threlfall where it is claimed that by studying the rotations around the vacuum manifold in a holographic model of QCD the goldstone mode studied in the original Sakai-Sugimoto model is not the correct physical state and that the original formulation which only includes massless quarks can be extended simply to incorporate massive fundamental matter and a massive pseudo-goldstone boson. The similarity of the quark bilinear condensate as a function of quark mass compared to the form in the non-supersymmetric D3/D7 cases with non-constant dilaton is interesting and it looks like there is more to explore here, especially in looking for agreement with the Gellmann-Oakes-Renner relation.

The weekend has been enjoyable and there's plenty to write up when I have a chance.

Linear, or otherwise

I've just presented a blackboard talk to the students on 'The linear confinement problem in AdS/QCD', a topic which I'm particularly interested in studying more myself. I spoke about the papers by Karch et al. 'Linear confinement and AdS/QCD', Csaki and Reece 'Towards a systematic holographic QCD - a braneless approach' and Shifman 'Highly Excited Hadrons in QCD and Beyond', all of which are clear and inspiring for future research.

I've rather given up on the summer school, which was either too elementary or a little too hand wavy, or just too intensive on subjects I have only a passing interest in (4+ hours in one day on CP violation from the B-meson sector is more than I can take). There's talk on several Beyond the standard model conferences in the far West of China and down in Yunnan which would be lovely to go to but they're not quite in my area. I'm keeping an eye out for a good cosmology conference, before the KITPC program which starts in September.

Cosmologists, string theorists and string cosmologists should all come to China for this program!

After completing most of the preparations for my talk yesterday I headed over to D22, a local bar with an eclectic mix of people, music and events, to watch one of their movies. Having seen clips on TV various times I was keen to see The General from 1927 with Buster Keaton. It's a beautiful film, dated and cliched but Keaton is such an incredible physical actor that everything else apart from his balletic movements and amazing expression are rather overshadowed. Slap-stick, especially of the modern variety doesn't do it for me, but Keaton is so seamless and so expressive that it's a joy to watch.

Looking at still photos of Keaton it's a strange contrast to the expression that come from his movements and if anyone knows a good biography of him I would be intrigued to know why this contradiction is so vast.

Having met him in person a little while ago, I had Jonathan Tel's 'Freud's Alphabet' shipped to me, courtesy of my sister, from England. This is a fictional account, based on the true story of Freud's last few weeks spent in London with terminal cancer. The book is split into chapters labeled alphabetically with Freudian symbols and the book becomes increasingly dreamlike and non-linear as Freud drifts in and out of his morphine haze. Tel's turn of phrase is playful and powerful in equal measure and as long as you don't require linearity and clarity in your stories this book is an interesting journey into dreams, metaphor and the subconscious. Well worth a read.

This links in to the Mario Vargas Llosa book I read while in Japan on the subject of a Storyteller in a Peruvian tribe, which is equally dreamlike, non-linear and imaginatively written. It's been too long since I read it to give it an in depth review but Llosa's story telling, both from his own narrative style and that conjured up for the storyteller's tales of a magical reality weave into each other naturally and give an eloquent picture of an ancient art.

I'm reading another Steinbeck now and enjoying this one as much as ever...expect a review soon.
