Language exchange

The summer cold is disappearing, work is going in the right direction, a host of new Couchsurfers are about to turn up and things are as non-stop as ever.

In my not so spare, spare time I've been doing some audio recording work for a publishing company out here which produces teaching material for schools. I have, give or take, a reasonably 'standard' British-English accent and this is rather sought after out here where the majority of English speaking expats are from the US, Australia or Canada.

For a couple of early mornings over the last week I've spent around 3 hours sat in a recording studio reading at varying speeds from very, very slowly to a reasonably fast, but clearly annunciated, rate on a variety of topics from Sherlock Holmes to cross-species animals (I've learnt a great deal about zonies, ligers (the largest cats in the world) and wolphins) and from World domination by China in 2057 to the history of global discovery. I've read poems and taught unknown millions of Chinese children how to say 'I love you' in Indonesian, Spanish, French and a variety of other badly pronounced languages.

I'll try and find out just how many Chinese children will be speaking with my accent over the next few years and should be able to get hold of a set of the language courses when they are published.

It's been another interesting experience, although I've found that talking almost non-stop for two and a half hours, at a very slow pace, can be exhausting. This has also meant some very long days, but the pay that one can get to do this sort of work is hard to turn down when you spend most of your time on a local wage - not that a local wage is hard to live on when accommodation is heavily subsidised.

I read recently that Beijing is one of the most expensive cities in the world. I can only imagine that this is almost entirely down to the cost of housing, which can be extortionate. One could easily live on a dollar a day out here if it were necessary.

---------

Anyway, later today I'm picking up a Couchsurfer from Malaysia who will be staying at my flat until next week. Couchsurfers from the States, Russia and the UK will be staying over the next couple of months.

Chinese lessons are back on this evening after a short hiatus and though I've been steadily working through the audio courses, I need to find some hidden minutes to go through the characters. Spare minutes are hiding from me more and more these days.

...Mathematica has finished spitting out numbers, I'd better find out what it all means.

Emergent Phenomena

This eight minute video is extremely exciting. I'd come across the ideas behind using semantic links within photos to create a whole much more powerful than the sum of its parts, but this short movie from a recent conference is well worth a look to see the incredible potential from something as simple as tagging. I've written a post a while back on tagging within personal computers because the idea of folders seems completely outdated to me. The post seemed a little dry, so take a look at the movie and realise what power can be gained from this new, but incredibly simple concept.

The link for the video came from Bad Astronomy Blog and you will find more information on this sort of system in Data Mining - one of my favourite tech blogs.

This step seems to be the difference between a random collection of cells to a brain with neurons connected by synapses. The numbers involved with such combinatorics are mindblowing and the emergent phenomena will be fascinating to see.

Big soup

A few sets of lectures on the birth of string theory, from those who were there can be found here.

I'm frantically coding at the moment but I wanted to post these pictures from The Bird's Nest. Taking my family and friends to the airport on Wednesday we asked the taxi driver to stop by the Olympic village, and though you can't go into the grounds, you get a reasonable view from outside:

KITPC opening II

(Continued from here)

So, the KITPC is open, on time, remarkably, after only a year and a half of the idea being mooted. The six story building has been formally opened, lectures have been held, students are seen buzzing around, the blackboards are full of musings and equations and though the smell of coffee hasn't yet infused the walls, I'm sure that's only a matter of time.

The opening ceremony was held in one of the grand rooms of the Great Hall of the People. Fred Kavli himself came along and gave a rousing speech, discussing his long term dream to be able to add to the sum total of humanity and indeed with 14 institutes set up around the world allowing for the cultivation and exchange of ideas and theories on both the most theoretical and applied ideas in the sciences, it seems that his dreams are being fulfilled. He spoke of his high esteem for the Chinese, both culturally and from an academic standpoint. At 80 years old, he walks tall and speaks powerfully on a topic which has clearly driven him to do great things, both financially and in parallel philanthropically.

A short extract from Wikipedia:

Already in his early teens while attending Firda Landsgymnas high school in Sandane this entrepreneur had visions of doing something for the good of humanity. A deeply philosophical person he is influenced by his high school studies of Nietzsche, Kant, Hemingway, Steinbeck, Faulkner and Dostoyevsky.

At 14 together with his brother Aslak he began his first enterprise creating wood pellet fuel for cars. During these early years during the Second World War and the Nazi occupation of Norway he experienced dramatic incidents. Due to the lack of fuel he would regularly steal fuel and lubricants from the enemy. Only luck saved him and his brother when they were observed by a German airplane patrol while smuggling weapons to relatives in the mountains.


The following speakers talked not only about the great efforts which have gone into creating the KITPC but also of the future efforts which will be necessary in order to place the institute as a true, international centre for excellence.

Michael Freedman
gave a talk entitled 'How topology will save Moore's law'. This was on the topic of quantum computation and in particular how one can study two-dimensional systems of interacting electrons, the topological states of which can be manipulated to give 'natural' quantum computers. If you get a chance to see Michael speak, this is a good advanced public level lecture and his musings on artificial intelligence emerging from a quantum system are interesting, if not terribly well-founded. Note that this is not the strong conjecture of consciousness emerging from quantum mechanics in the brain (a la Penrose). My uncle, sister and friend came along and with a psychology and two mathematics degrees between them agreed that they understood a lot more than they had expected to.

Around 11 we left the Great Hall of the People and headed into the furnace outside. We knew that it was hot, but hadn't realised that it was the hottest day in Beijing for over 50 years - 39 degrees in Tiananmen. I spent the next few hours going around Qianmen market nearby with my family, dodging in and out of the shadows and haggling for gifts to take back home.

I didn't have a chance to see the lectures which resumed on Saturday afternoon in the KITPC. The two day conference on frontiers in physics included talks on extra-planetary life, string cosmology, quantum computing, laser powered particle acceleration and much more.

The Powerpoint files can be found here and videos should follow.

Now the first of the programs, 'quantum phases of matter' is starting officially tomorrow and I will try and give an update when video files start to be uploaded.

Again, I urge people to come along to these programs and please contact me if you have any questions about coming to China.

Testing the waters

The police arrived within perhaps 5 seconds of us getting the large, multicoloured parachute out in the middle of Tiananmen square. I had warned Phill that perhaps the authorities wouldn't view parachute games in the same way that he did and sadly, on this occasion, my guess was right.

Having spontaneously organised two large crowds to play games on the Great Wall and a couple of classes at a local primary school to spend an hour or so having a lot of fun, meant that taking the props cross-continent had been worthwhile. Tiananmen would simply have been the icing on the cake. The puppets (Susan the tarantula, Blodwyn the rather amorous orangutan from the Welsh valleys and Barbara the sheep) came along almost wherever we went and were met with a huge range of amusing reactions, from shock and incomprehension to laughs and smiles, they did at least seem to placate the policemen at Tiananmen.

Sadly I don't have photos of the all too brief appearance of the parachute on the square, though there is evidence of the Great Wall games. A few here and many more, including more Dashanzi on here.

KITPC opening

Photos from the opening ceremony of the KITPC at the Great Hall of the People. Amongst others there were speeches from Fred Kavli, David Gross, Shing-Tung Yau and Michael Freedman. The first photo is of the KITPC itself. A post with more content is in preparation.

Flash

I've just returned from a photo shoot, which I will explain at some point soon. My family is still here so I'm trying to cram in as much work as possible in the hours available. Hopefully things will ease up around the weekend and I can start to fill in a few blanks.

For now, the widget to the left called 'blog posts and news of note' is a link to my Google Reader which allows me to share stories which I believe to be noteworthy at the click of a button. This can be placed as a widget into any blog by copying a few lines of code. Ironically, anyone who reads this blog through a feed reader will not be able to see this widget.

On the move

I have my sister and uncle out here in Beijing at the moment (complete with puppets and parachutes - photos may follow) which means that I'm working in the day and seeing them in the evenings, hence no extended blogging time. Beijing has opened its skies today and the plans to see the Forbidden City have probably been washed away.

Last weekend was very enjoyable, meeting up with fellow blogger, Michael, to celebrate the release of his book 'The Pisco Kid' - sounds intriguing. We dined at Houhai which is a lovely area to come on a summer evening and steal a relaxed few hours.

A couple of photos from the weekend, but that's all I have time for now - work to be finishing.

Blogrolling

Chaoyangmen as taken a couple of weeks back:

Click to view the full image. Panorama created with ArcSoft Panorama Maker 4, by far the best software I've found so far.

The blogroll in the left column has finally been updated to reflect most of my Google Reader content.

The Criteo blogroll to the left is currently underwhelming me with the content that it's providing. As I wrote a few posts back, this tracks which blogs readers of this blog also read, though it can only track blogs with the criteo tracker installed. It's going to take more time and more people to install this for anything useful to come of it and it seems that people are being put off too soon to really see any benefit. I'm going to give it 6 months and see what happens.

Reflections

Five months to go here in Beijing, and that thought makes me rather sad. Perhaps just two months ago I would have said that I thought it was the right time to be moving on. My plans are still firmly set and I am very much looking forward to making my way to Galicia to experience a new culture, pick up a new language and work in a different environment.

So, what has changed in the last couple of months? Nothing of any discrete alteration, just a gradual change which means that I feel more and more at home here and the comfortable, easy life of both a physicist doing what he loves and an expat living a semi-expat life makes for a fine existence. I still get an itch every few months and Beijing just gets a bit too much, the shouting, the spitting, the pushing and the pollution can get you down when you're feeling edgy or vulnerable, but I've been lucky to be able to escape, if only for a day on such occasions.

Now summer is here and Beijing becomes an altogether different beast. The chilled edge of winter cutting through to your core has vanished and this makes life infinitely easier. If only to be replaced by hungry mozzies and hot nights, I much prefer the latter.

One thing that has definitely changed is, as is so often the case, a matter of the language. On arrival in Beijing I knew perhaps 100 words and could use just a fraction with any comfort. One of the hardest things to understand was people's attitude to becoming my friend. I've had the same reaction from every expat I've met who arrived in China with a similarly small Chinese vocabulary.

I met many people in the first few months here who I would chat with for a few minutes or perhaps a few hours, on the street, in a bar or cafe or a friend's friend. On many occasions they would hook onto me as a best friend, and this frequently felt uncomfortable. Sadly it often felt like they wanted to be my friend because either I spoke good English and could help them, or they wanted to know about English culture, or they wanted me to help them to get a job. Of course this was not always the case and there is nothing inherently wrong with wanting to know somebody for these reasons. It just felt uncomfortable and I found myself making promises to ring people or go to dinner with people and never did. I still feel bad about that and I also feel bad because there were genuinely interesting individuals who got bundled into the same mass of mobile numbers and name cards.

What has changed is unexpected but a real pleasure. At first I met people who were interested in me because I could speak English, I was rather unusual and almost like a new toy (part of this may be tied in with the one child policy but I'm not sure how speculative that guess is). As of the last few weeks I've started bumping into people in various situations and have spoken Chinese with them. Although it's bad, broken Chinese and about fairly basic subjects, the smile that I'm received with for being an expat who has made an effort and is interested in the people and culture is a very different smile from that which greets the expat who can help with English practice.

When I was taking photos of the strange metallic sculpture I posted last week I met another photographer there, from Anhui province, in the East of China. I told him I thought the sculpture was beautiful and and interesting piece to have on the street and we started talking about our backgrounds and life in our home towns. We must have spoken for half an hour, but it felt like a true two-way exchange, and I left feeling elated by having met an interesting person on the same level that I would in an English speaking country.

This has happened a few times now, on the street, in taxis and bars and it seems, naturally, that the warmth of the welcome to a foreigner who can speak the language is far greater than I had known before.

As I say I have several, though not a great many, Chinese friends and those in the department who I've got to know, I do not put in the same category as those who have latched onto me in the past after a few minutes of talking English. I would still like to build stronger friendships with those in the department.

Anyway, that, I'm sure is a great part of my increased comfort of living here. When I return to see my friends they should not expect me to be speaking fluent Chinese but simply enough to get by and have a basic chat with a stranger.

Of course I'm going to miss the food greatly, anyone who has read more than a few posts of this blog will know that it's a great obsession of mine, but I hear that the food in Santiago is excellent too and I shall continue to explore whatever I can get my hands on. (See here for a rather fuzzy photo of the Hunan bee pupae and bamboo worms I had last week - pretty tasty!)

The mix of Western and Eastern culture in the arts also makes for a fascinating time out here and a trip last week to see the first 3 hours or so of the Kunqu opera, The Peony Pavilion was in stark contrast to the experimental electronica, Chinese punk and techno which I'd seen throughout the previous week. It doesn't have quite the finesse and simplicity which so attracts me to Kabuki but the movement, the poetry of the lyrics (translated very well on subtitle screens) and the exuberant colours of the costumes make it a fascinating art form.
Peony pavilion 2
Peony pavilion
The voices are not easy for most Westerners but I find it substantially better than the Beijing opera, three hours of which would definitely be too much.

Anyway, a few reflections on recent changes. I would really recommend any expat who comes out here for any length of time to make as much of an effort with the language as possible. You will have a great time out here without any Chinese but you will love the place if you can truly integrate. I just wish I had learned this sooner and had more time to put these lessons into practice.

Not set in stone

Many thanks to Toomanytribbles. My previous nominations can be found in this post and are all well worth a visit.

While I'm in a mildly gloaty mood I should say a) that scientists who are also photographers or vice versa should join the 'scientist photographer' group on Flickr for a bit of fun and b) My picture was chosen last week in the weekly competition, the topic being 'Memories due to concrete'.

More on the KITPC

The two day opening ceremony for the KITPC is coming up in a little over a week. After the official opening at the Great Hall of the People (with talks from Fred Kavli amongst others) there will be two days of lectures at the KITPC from many highly eminent scientists. The morning of the 26th will see a public lecture given by Michael Freedman, winner of the Fields medal for his part in the solution of the Poincare conjecture. Title:

'How Topology will save Moore's law' - Some thoughts on the human condition expressed through the history of the concept of "number." This concept carries us finally into the interface of topology, quantum mechanics, and computer science.

After this there will be lectures on subjects from quantum information, the search for habitable planets, laser technology, dark matter, the origin of the universe (from Henry Tye) to the future of physics, both worldwide and in China.

The closing speech will be by David Gross on Sunday the 27th. I'll report on what I get a chance to go to. I'll try and get some photos of the building too to give those who are thinking of coming to the future meetings a bit more of an idea about the place.

Turing universality prize from Wolfram

Not quite the big bucks of the Millenium prizes, but a nice $25,000 for proving that an exceedingly simple Turing machine (an abstract symbol manipulations device) discovered by Stephan Wolfram is in fact a Universal Turing machine (A Turing machine which can simulate any other Turing machine, and therefore any computer program, which generally have much more complex rules).

The contest is to show that a particular two state, three colour Turing machine is universal.

This comes from the newly created Wolfram blog. See here for details about the competition, more about Turing machines, and more about this particular, incredibly simple algorithm.

[Thanks to Blake Stacey for pointing out the typo in the above. Indeed the Universality of the 2,5 Turing machine had been proved already, by Matthew Cook]

New Toys

Having spent all of last week preparing for my big talk on Friday and most of the week before away from the office, it's only now that I plunge back into my projects. I've managed to cut the ones that I'm working on reasonably full time to just three and have shelved a couple for now. It feels a little more manageable but still a juggling act.

The talk was enjoyable though rather tiring. At two and a half hours it was a great chance to go into some of the details which I usually have to leave out of a talk. As always lots of good questions although I fear that the students who were not versed in AdS/CFT were a little lost.

Last week we also had a talk on unparticle physics which is taking off, as expected. As a phenomologist friend of mine pointed out, it seems strange that people are using this model which is so little understood and may have so many possibilities to start studying precision physics. Georgi's paper which talks about distributions of missing energy from a generic unparticle physics model seems a long way away from corrections to g-2 of the muon or B-Bbar mixing. Still it's interesting to watch a new subject develop and I'm sure there are surprises to come.

Anyway, with little time to blog recently it's all been adding up. I'll randomly update on recent events as I have spare moments. The big news from this weekend was that I finally picked up my camera, a 10.1 Megapixel Canon 400D (Digital Rebel XTi) SLR with a 17-85mm Canon Lens. Suffice it to say that I am both hugely excited about having a new toy and overwhelmed by what it can do.

I've been spending a bit of time over the last few weeks reading up about digital SLR photography and techniques with this particular camera and so it felt remarkably comfortable playing with it once I'd set it up. That's not to say that the shots are great by any means yet, but I can see what it's going to be capable of. Though my point and click is just 3.1 Megapixels I've had it long enough to know both its limitations and what it's good at and so have managed to get some pleasing results from it over the last 3 years. With the new baby it's clear that it's much easier to get a bad shot (unless you're on fully automatic) but the possibilities of getting a superb photo rather than just a mediocre one are also vastly improved.

I spent Sunday afternoon and evening walking around the old Summer Palace (Yuan Ming Yuan) which was destroyed by the British and the French around 150 years ago - a particularly embarrassing period. Though the buildings are all almost entirely destroyed, the lakes are still beautiful to walk around and the place is a lot more peaceful, tourist-wise than the new Summer Palace. Yuan Ming Yuan is just by the West Gate of Tsinghua university, so you can do both in a long afternoon. There's also the famous West Gate barbecue restaurant where you can stuff yourself with chicken wings, chicken hearts and lamb kebabs, while sitting with a hundred others on plastic chairs by the pavement drinking cheap beer and breathing in the car fumes. I give it a bad image but this is a truly enjoyable part of Beijing life - the casual streetside eateries where summer nights are easily lost.

Anyway, of the 350 shots I took yesterday there were a few which show some of the nice bits of Tsinghua university:
Tsinghua waterfall 1
Tsinghua peakock
and Yuan Ming Yuan:
Yuan Ming Yuan reflections 2
Yuan Ming Yuan sunset
There's clearly a lot still to learn about the camera but I'm currently having a great time finding out.

Pandora restricted

A sad day indeed when a site has become restricted for us, not because of the Great Firewall of China but because of new licensing laws implemented in the US. Pandora is down for all of us outside the States, as I found today when trying to access the site:

Dear Pandora Visitor,

We are deeply, deeply sorry to say that due to licensing constraints, we can no longer allow access to Pandora for most listeners located outside of the U.S. We will continue to work diligently to realize the vision of a truly global Pandora, but for the time being we are required to restrict its use. We are very sad to have to do this, but there is no other alternative.


(Thanks to Piskokid whose site I just came across and found the above information)

Interlude

I'm still here, just. Have been preparing to give a three hour talk tomorrow morning. Today was the first of two days of a workshop on AdS/CFT with just four speakers. I don't know what the first two said, as it was all Chinese to me. My talk 3(\pm 3) paths from AdS to QCD may or may not be pitched at a suitable level but whatever happens I'm sure to be exhausted afterwards. Will report when I've recovered.

Back to the fray

The end of an eventful and enjoyable holiday and we rush headlong back to work. I've been thinking more about my overall views on life in China and the fact that I have less than 5 months left here. I'm going to be really sorry to leave the place and will certainly come back in the future. I can't see myself living out here forever at any point but somehow a two week trip here or there doesn't feel like it can do justice to any small part of China. Anyway, I'll write more when I have a spare moment.

I'm giving 3 hours of talks on Friday morning at a workshop that I know next to nothing about. I know neither the title nor the exact location or, most importantly, the range of people I will be lecturing to. I know there will be 3 hours on AdS/CFT the day before so I can try and simply build on this.

Anyway, more to write before Friday but I wanted to post a few photos from the last few days.

I took these photos in Haidian district of a new piece of sculpture that looked stunning on this wonderfully blue-skied day.

Auto blog-rolling

There's a new toy to the left of the blog which I'm giving a test-drive. I was contacted by Criteo to see if I would like to use this product which they've developed for blogs.

The information they gave me on this auto blog-rolling tool is:

What's it all about?

AutoRoll is the blogroll of your readers. It's a widget that displays links to the blogs that your readers are visiting the most often.

How does it work?
We trace the number of visits of each unique reader on each blog that has installed AutoRoll. The more often a reader visits a specific blog, the greater his affinity is with this blog.

What are the benefits for you?
First of all, you will provide your readers with a very entertaining blogroll since it's based on other readers with similar reading habits. Moreover, you will attract highly qualified incoming traffic to your blog. Indeed, as other similar blogs display your blog on their AutoRoll, they will feed you with new readers that have a strong affinity for your blog.

Sounds clever so I'll see if it's useful. I guess it will take some time to collect data about the readers of this blog.

Midi take two

The Midi festival is one of China's greatest music events, pulling in local and International talent alike. For four days Beijing's Haidian park is filled with tens of thousands of music fans excited as the scene explodes in so many directions. Punks, goths, rockers, emo fans, hip-hop junkies and techno heads get together to dance and jump to their rythm of choice. I hadn't expected to see either heavy metal or contemporary art as big things here before I got to China but in all their rebelliousness they are, at least from the outside, thriving - I'm not enough 'in the scene' to know what is and isn't allowed.

Anyway, I have to admit that though I enjoy the local music scene here I don't go to Midi for the music, but for the atmosphere and the diversity of people there. Yesterday was a perfectly sunny day with temperatures around 30 and necks and backs crisping up nicely. I was caked in enough sun block to keep me going completely pink.

So, we sat around, saw a few bands, wondered the parks watching people sat reading in the sun. A few snaps from the day:

My personal favourite, as the sun was setting:

Post festival we celebrated the holiday with a night of Korean soju, rather like sake and far too easy to drink! Some didn't relish the bright sunshine the next day but I seem to have escaped lightly.

Tomorrow I have to get back to work though it will be relaxed, in a cafe which is certainly my favourite way of working.

Noodly fun

The one week May Day holiday starts today here in China though many people will be firmly seated in the department. I'll have to spend some time there this week getting my talk ready for the upcoming workshop at Beijing university.

Yesterday I went with a few friends to one of the best Sichuan hotpot restaurants in the area and had a fine feast of all the usual suspects one finds in the ma-la (numbing and spicy) sauce. It's always rather disconcerting to have the huang na ding fish, which is so freshly killed that it has to be held under the boiling oil for a few seconds to prevent the thrashing around from splashing the diners.

This particular restaurant has hand-made noodles, pulled to entertain the crowds. Take a peek at the video I took yesterday evening.

A Sichuan hotpot restaurant is traditionally loud and crowded with a frenetic atmosphere, waiters speeding about balancing trays piled high with ingredients to boil in the soup in front of you and a steady stream of baijiu (white spirits) flowing to keep the guests relaxed. Downstairs diners waited while playing mahjong and poker, relaxing with cups of tea before they were rushed to their tables.

-------------------

Today is the (sixth) return of the Midi festival which was a lot of fun last year and a great place to take some snaps. The four day event is brining all the local talent out as well as around 20 international bands. Along with Goldie making an appearance in Beijing next week and my first real experience of Chinese theatre on the 11th it's looking like a fun start to the month.

Temperatures are now climbing to the low thirties having only just risen above freezing a month or so ago. We seem to have escaped the sandstorms which plagued much of North Eastern China last year though my flat still picks up a good heap of dirt if I keep the windows open for any length of time.

If you're worried about traveling for the May day holiday where you are, just remember that there will be almost 100 million Chinese travelling around the country here over the next week. The lines outside all travel agents are monstrous and, until they all get out of the city the roads are in gridlock. Happy May Day, everyone!

Mouse brain simulated on a computer

OK, half a mouse brain, but even so this seems to be an incredibly exciting step.

From the BBC comes the news that the modeling of around 8 million neurons with up to 8000 interconnections each was conducted on the BlueGene L supercomputer and...

The vast complexity of the simulation meant that it was only run for ten seconds at a speed ten times slower than real life - the equivalent of one second in a real mouse brain.

On other smaller simulations the researchers said they had seen "biologically consistent dynamical properties" emerge as nerve impulses flowed through the virtual cortex.

In these other tests the team saw the groups of neurons form spontaneously into groups. They also saw nerves in the simulated synapses firing in a ways similar to the staggered, co-ordinated patterns seen in nature.


I'd love to know from experts how realistic this is and how much further we can go with current technology.

Update: From what I've found on the subject it seems that the link to the mouse brain was simply a comparison of the number of neurons and synapses. The structure, unsurprisingly was not there. The paper is supposed to be linked to here but doesn't seem to be working right now.

Upcoming KITPC events

It was almost a year ago that I first wrote about the KITPC (Kavli Institute for Theoretical Physics in China) when David Gross came out here prior to Strings 2006 to announce officially the deal to build the KITPC. (original piece here).

Well, the building is completed, there are people milling about in there and the interviews which I mentioned a couple of posts back were for management and computer staff for the department.

At the end of May the KITPC will officially open with a ceremony filled with the great and the good. Fred Kavli himself will be out here as will David Gross, Shing-Tung Yau and many other eminent physicists and mathematicians from around the world. We'll be heading back to the Great Hall of the People for this and I'll report on events as they happen.

Anyway, one of the reasons to write this post is as a piece of advertising. This year there will be two programs running at the institute.

The first is a two month program starting in June on "Quantum Phases of Matter" and the organisers for this conference are Sankar Das Sarma, Eugene Demler, Yu Lu, Fu-Chun Zhang and Xiao-Gang Wen. It says the deadline is over for applications for this program but it's always worth a go.

The second program is more relevant for my work and looks like a superb event. "String Theory and Cosmology" will run from September 1st to December 15th and is being organised by Miao Li, Shamit Kachru, Eva Silverstein and Henry Tye. The blurb reads as follow:

String theory is the best motivated theory that can address fundamental issues like physics beyond the Standard Model, the origin of our universe, the quantum nature of gravity, the mystery of black holes, dark energy, supersymmetry and the dark matter.
Studies of the cosmic landscape, model/vacuum building and time-dependent solutions are making contact between theory, phenomenology and cosmology in new and exciting ways. WMAP and PLANCK, together with LHC, have begun to usher in a new era of string cosmology and string phenomenology.

This program aims to take advantage of all these recent and coming developments, with a slight emphasis on cosmology. The program hopes to bring together string theorists with an interest in phenomenology and/or cosmology, and cosmologists, particle astrophysicists and phenomenologists who are interested in new ideas coming from string theory. Mathematical string theorists who are interested in these issues are most welcome.


There isn't much more information up there yet but the idea will be to have lecture series and workshops running through the three and a half months with people staying in residence at the KITPC for varying lengths of time.

This is a great chance for China to represent itself once more on the world stage in its scientific capacity and a part of that is for others to come and see Beijing at work.

I wrote a piece just before the strings conference last year as a Beijing survival guide which people responded well to. I'm very happy to answer any questions, either by e-mail or in the comments if people have queries about coming here. That includes information about China and information about the workshops. I can ask for the website to be altered or added to as people see fit (not that I have any great power over it but that those in charge are down the hall).

It's been my pleasure over the last couple of years to help several people make up their minds to come to Beijing either for a long time or for a holiday and then to settle in. Many people don't realise that Beijing really isn't such an alien world and is certainly a highly developed city, with both running water and electricity - and more internet connectivity in the cafes than I witnessed even in Tokyo.

Anyway, I think that these events will be a fantastic chance both to bring together some of the top scientists working in these research areas and to see Beijing as it readies itself for the 2008 Olympics.

Royal Society science book shortlist

From the big questions of cosmology through headline making scientific findings, personal journeys in discovering about disease to history-through-science and science-through-history, biography, the brain and the anthropic principle, there's a good range of subjects in this years Royal Society short list of the best popular science books. Of the wide ranging subjects I'm most taken with the Erik Kandel's 'In search of memory', but most of them look enjoyable.

Time warp

My job, and that of those around me is, in theory, to tackle some of the deepest questions about the universe around us, both on the largest and the smallest scales, to gain a true understanding of the nature of reality and to discover what are the underlying structures of the amazing phenomena we see in nature. Whoever, as far as I know nobody has tried to solve the strangest puzzle of them all: how on Earth did it get to Friday already? Yet again I'm at a loss to know where the middle days of the week vanished to. I've checked my Mathematica files and my LaTeX scripts and some of them are indeed date stamped with the intervening time period, but like an ancient mathematical riddle Monday+Friday seems to equal a full five days. I'm at a loss.

Anyway, however we got here, Friday arrived although the weekend is not upon us, at least here in Beijing. The 1st of May marks the start of a one week holiday and, as always, we must work the preceding weekend to earn our rest. The holiday starts on Tuesday so we still have a bit of a slog until we're given our respite.

This morning I spent interviewing nine candidates for various positions at the KITPC, from management to computer administration. My job was simply to spend time with the candidates before the official interviews (a 15 minute presentation in front of 20 or so members of staff) to chat informally and gauge their English level. It doesn't seem appropriate to make any comments on the results, but it was another interesting insight into life here and an enjoyable morning spent talking with the prospective employees.

I still need to give full reviews of the concerts last week but before I talk about the music I wanted to mention the strange phenomenon of Chinese crowds I encountered. ...

It's no secret that the Chinese are not known for their queueing skills. As a Brit I spend a good amount of my time in queues and think that it's a jolly good way to wile away my hours. Here in China any queue which forms through random, chaotic processes tends to disintegrate within a few seconds. I find it frustrating that when I'm trying to buy a ticket, get my lunch or wait for the train, the only way I've found to get what I want is to stand my ground very firmly, which is sometimes a strain for the blood pressure levels. I haven't found myself pushing people yet, but it's been close on occasion.

Before the Sonic Youth gig we were supposed to have a show from one of Beijing's top rock bands - Carsick Cars, who I haven't seen before, though the guitarist had been accompanying Elliott Sharp the previous week. All 1000+ of us piled into the venue a little after 7 on Monday evening waiting for the 7.30 start of the support band. But we waited and waited, with the occasional blur of a guitarist or roadie seen through the door at the back, but nothing more than that...for two and a half hours. Standing in a concert venue for two and a half hours with nothing to see isn't my idea of fun (no orderly line, you understand). What amazed me, however, was that had this been in England, land of patient, needless queuing, there would probably have been a riot within half an hour of the band's absence and a painful chorus of 'why are we waiting' would have kept people going until blood was spilt. However, here in China, where my toes are constantly stepped on when waiting for my baozi for breakfast by an overly eager security guard or impatient school kid, there was an eery calm and complete acceptance of the situation. Some of the Westerners in the crowd attempted to start a round of calls for the band, but they just sounded a bit out of place.

I wonder how much longer the crowd would have stayed patient. The way things were going I couldn't see the calm breaking for some considerable time to come. Lesson learnt: Queuing is a no-go here but patience is a true Chinese virtue!

Earth-like extra-solar planet discovered

Take a look over at Bad Astronomy Blog for information about Gliese 581, the first Earth-like extra-solar planet discovered. A little larger than the Earth and the right temperature to have liquid water. Exciting stuff!

Weekend snaps

Truly no time for blogging at the moment but a few pictures for now from this weekend, which included:


amongst other things.


All of them are worth writing about and I'll do so when I have a spare moment.

Unparticle physics

I only stumbled across Howard Georgi's latest work when his paper "Another odd thing about unparticle physics" appeared on the Arxiv today. Clearly there was a first odd thing to know about unparticle physics, which leads the reader to "Unparticle physics". This is a very short paper with some fascinating commentary on a possible, previously unremarked scenario for LHC phenomenology (unremarked as far as I'm aware).

The idea is to have a non-trivial scale invariant sector, at least with an IR fixed point, and see how the coupling between the normal particle sector and the scale invariant sector, using effective field theory techniques, effects the low energy physics. The strange terminology is used because in a scale invariant theory the quantum mechanical treatment of particles doesn't make sense and Georgi names the 'stuff' 'unparticles'. The question he tackles in the first paper is what signals one would see in the accelerator if there is a coupling between unparticles and particles. The answer is that although the theory may be highly non-linear, the conformal nature means that the correlation functions can be understood simply through the scaling behavior of the unparticle operators.

Depending on the scaling dimension of the 'stuff' the signature gives a different decay width of regular particles as a function of energy. This very specific signature would be quite clear, giving signals of missing energy at particle accelerators, in a different form from SUSY or large extra dimensions.

The paper is short and clear and gives a hint that there's lots of interesting, easy phenomenology to extract from this strange but not necessarily crazy model. Two new papers today follow this although in the conclusions of the latter paper it seems that the signals from the LHC would not be so clear.

Bowling them over

I don't include Google ads on here but I'm happy to promote products and services if I think that they're worthy of a plug, especially if my family and friends are involved.

My father went into semi-permanent early retirement in order to work twice as hard as ever before (not that he ever slacked off) to start turning bowls - the obvious sideways step from chemical engineering and scientific consultancy. His website has lots of his work but I thought the new postcard was worth a post here. So, if you are looking for fine wood turning, take a look at the site.

Odds and ends

I continue to make excuses of being too snowed under with work to blog extensively at the moment, and this excuse holds for the time being. The projects are moving in the right direction, and there's plenty else going on besides. I'll be writing my talk 'Three paths from AdS to QCD' over the next week or so which I'll be presenting at a workshop in May.

I'll be working until late this evening before going to a concert by Elliott Sharp, at D22, which should be a lot of fun. If anyone picks up on this and enjoys experimental electronica/jazz then come along to see a classic, if not strictly classical, composer.

On an aside-aside, I have The Amon Tobin mix of the Chris Morris 'Bad Sex' track whirling around in my head, which is as intense as it is strange. Amon Tobin is one of my favourite artists and together with the tangential world view of Chris Morris, this is bound to produce something warped and fascinating. Again, if you like your music slightly rough and a little experimental then look out for this track.

Sonic Youth tickets have been booked for Monday which should also be superb and tomorrow the artWALK Beijing event starts at Dashanzi at 5.30.

A random cooking challenge for anyone interested in the new science of flavour pairings: Take a look at this molecular gastronomy blog to find out more.

Flip Tomato continues to give well written accounts of his journey into particle physics, this week discussing chirality, soon to be followed by a posting on orbifolds.

From a 2003 talk by Weinberg comes four golden lessons for theoretical physicists. This article deserves more discussion but, time, etc...the review at the bottom of the linked page is depressing (particularly in relation to points 3 and 4) and, in my opinion not a healthy way to go into theoretical physics. If you're going in with these sort of thoughts, you're probably not in the right game, IMHO.

If you're a fan of internet radio, for instance Pandora, then take a look at this petition which is attempting to stop the possible change in licensing fees which will cripple many of these sites.

Finally, a call for advice. My camera is on its last legs, which is a slightly better state than my ipod now finds itself. I'm seriously considering investing in a digital SLR and the Canon 400D (also known as the Digital Rebel XTi) seems my best bet. If anyone has any invaluable advice on this I'd appreciate the extra input, all reviews I've seen have been pretty good.

Grease Monkey tips

I was in the office very early this morning and thought I'd try and fix a few pet gripes with the internet which have been bothering me for a while. When this is the case, Grease Monkey usually has an answer.

Grease Monkey is an add on to Firefox which allows users to write scripts which alter how a webpage looks and acts. As a simple example, if you don't like the Google background being white you can write a script which takes the source for the google page and turns the white to any colour you like. This is a trivial example and what is most helpful is that many people have already written a plethora of codes which you download and are automatically integrated into Firefox, via the Grease Monkey addon.

I still use Hotmail, purely for historical reason, and the advertising banner which takes up roughly half the screen is both an eyesore and inconvenient for viewing e-mails. Use the Windows Live ad remover to get rid of this and fill your screen with e-mails again.

I've been very impressed with Flickr since starting to use it a few months ago. One of the common complaints however is that viewing photos on a white background isn't the best way to get the most out of them. This addon to change the background colour does the trick though it leaves a few residual ugly spots.
Flickr

The LaTeX for blogger script is another nice one, especially if you are using a blog for your collaborations, which I know try and do.

Hope this is of use and if others find particularly useful scripts then please let me know.

Public awareness

I figured that having never been on television before, a short interview on a program with an audience of around 200 million on a subject I know nothing about would be a good step into the limelight, a tentative dip in the water such that nobody would notice, if you like.

Yesterday I received a message from my English student who is rather a big player in one of the CCTV channels (Central China Television), asking me if I'd like to be on television to talk about mobile phones in the UK. I mentioned that I knew almost nothing about this topic and the mere fact that I have one does not give me any expert status. Yes, but you're from the UK, was the reply to which I had no good response.

My student has been extremely generous to me and so I figured that a) I owed them a favour and b) It would be another interesting experience if nothing else. I checked at this point that it really was OK that I knew nothing about mobile phones, to which the answer was positive. I spent a few minutes in the afternoon checking up on ofcom and finding out about the ins and outs of the usual mobile contracts and the like.

I was picked up in the evening to meet the crew and we went for a fancy Japanese meal in one of the CCTV owned buildings. Sake was flowing but I reasoned that the commandment 'though shalt not blog whilst drunk' probably held for appearing on TV, too. I tried to press them on what I was going to have to say or do and the information came thin and diluted with sushi. How much does it cost for a mobile phone call in the UK? Do you have to pay extra for calls between cities in the UK? Did you know that in China people have to pay more between cities? Were the few hints I got. I would have an interpreter and the questions would be very simple.

We set up the camera in the main atrium of a hotel complex where I stood facing the camera and the interviewer along with the interpreter to the side. I was still trying to find out a bit more when the camera was turned on and they started asking questions.

First the easy stuff, some of which I replied to in bad Chinese and some of which I would turn to the interpreter for assistance.

Q. Where are you from, how long have you lived in China and what do you do here?
A. (reply in Chinese)

Q. (Various questions about how much I like China and where is my favourite city)
A. etc................

Q. Do you own a mobile phone in the UK? and how much are call charges in the UK
A. Yes, I do. (I explained a little about the different rates for different monthly tariffs, and the fact that I probably paid about a penny a minute - guessing wildly).

Q. Do you own a mobile in China and how much do you pay a month?
A. I do, and I pay between 25 and 50 RMB per month (around £2-£4).

Q. Really? (Looking slightly worried) how come? That's so little.
A. I tend to text more than call, I use msn and skype to speak with friends and I would rather see my friends than talk to them on the phone (feeling slightly smug before realising that this is a good way to look like I haven't got many friends).

Q. Do you have to pay extra for long distance calls on mobiles within the UK.
A. As far as I'm aware calls within the UK on a mobile phone are a fixed price for each contract. They vary with time but not location, but to call out of the UK costs more...(goes on a little).

Q. Do you think it's right that people in China should have to pay more for calls between distant cities? (It appears that my interpretation of this question may have been incorrect).
A. (Slightly taken aback at the lack of information given for me to make a judgment on) If it costs the companies more to set up a long range network then I can understand that they would charge more for this service.

Q. But you know that it costs them just as much to connect you on a long distance call in China as a short distance call?
A. Well if that's the case then it does seem strange, though the company clearly has to make money, it's a business, and perhaps by charging more for long distance calls your short distance calls can be made cheaper.

Q. (Rather puzzled - definitely not expecting this answer) but do you think that it's fair?
A. (Feeling that I wish I had more background to this and reword my last answer with a few extra points).

At this point the cameraman steps in, having understood my translated response and asks if I really understood the question, how can I think that it's right for people to have to pay more for this service?

Q. You know that most Chinese people think that this is terrible?
A. I didn't, but not knowing the situation in detail I think it's possible that people are having to pay less for short distance calls, offset by higher priced long distance calls.

(Interviewer is looking rather worried about my capitalist propaganda)

Q. Thank you very much.
A. Thank you.

Not quite what I expected and certainly not what the interviewers had expected. Apparently they had interviewed an Australian woman on the subject earlier who thought that the situation was terribly unfair.

It seems now that they may have been telling me that the price of phoning from different cities varies, which seems marginally less reasonable. I also only realized afterwards that it is the government here who decides on the cost of mobile phone calls.

It was only afterwards that I dared ask how many people watch this show, to which the response was roughly 200 million.

Well, another experience at any rate, I'm not planning on watching it personally, even if they do find enough after the editing process to call an interview. I can't help but feel completely bemused and indeed amused about appearing on a program in front of four times the population of England.

JTA continues...

Disconnected

Something very strange is going on today! First my ipod has inexplicably died overnight (inexplicably other than falling onto the tracks at Munich railway station 6 months back). Died as in the hard drive refuses to move. This was always going to be the portent to a slightly odd day and we're only half way through.

My local mail account then packed up, suddenly it says it's too full though I had deleted a large file several days ago, purged it and hadn't received anything unwieldy since.

30 seconds later my hotmail account told me that I had sent the maximum number of messages in a 24 hour period. I've sent less than 10, as far as I'm aware, and I find it hard to believe that this is stretching my bandwidth.

30 seconds after this my gmail account opens but refuses to let me compose a mail. I am now disconnected from the outside world apart from this blog!!! Is the Nanny just having a particularly spiteful day?

Not sure where this is leading to but it's all pretty tiresome.

As we expected

There have been a couple of recent experiments which are definitely worth a more complete blog post which is in progress, but has to wait for now.

First of all,
MiniBooNE returned the result which many expected that there is no need for sterile neutrinos. This neutrino oscillation experiment receiving a neutrino beam from a collider has falsified the data from LSND which part of the collaboration claimed gave evidence for sterile neutrinos. From what I understand the LSND group was so split on the evidence that two papers were written disagreeing with one another. Anyway, there are good posts about this at these various locations

Secondly another interesting experiment with unfortunately unexciting results has tested frame-dragging, as predicted by general relativity and showed that it holds to within 1% of the predicted results and within half an error bar of the experiments resolution (See here and here for discussions).

While I'm posting up a few links I'll add Strange Maps as a worthy visit if cartographic curia is your bag. It appears to be mine and there are plenty of surprising and intriguing bits of trivia to be picked up from this site.

Art for the people

I've written recently of the Bird's Nest and in the past about the new CCTV building. Recently from Toomanytribbles came this video of the Ren Building, currently under construction in Shanghai which looks like fun.


I spoke in the above post on the CCTV tower about the odd dichotomy of the freedom to build outlandish buildings as the government spends a lot of their time making a statement to the rest of the world. There's some truly hideous architecture in Beijing but there's also some startling and attractive buildings going up around the city.

English Corner ideas

English corner returned this week and I managed to collect a couple of hours worth of material this afternoon.

It's difficult to find material online, simply because the students are all pretty advanced and the last thing I want to do is make it feel like a class. Most online EFL information is either too basic or too much like being at school for my purposes. A game of Call my bluff turned out to work pretty well however.

Having chosen five words for each team, that the students were unlikely to know, I gave each of the two teams the correct definition and asked them to come up with two more false but plausible definitions for each word. They then explained all three definitions of each word to the opposing team who had to guess which one was correct. As always I was impressed with their imagination and lateral thinking. Spoonerism was defined to be the philosophy of one who is born into a rich family (with a silver spoon in their mouth), a somnambulist was an expert in cognitive psychology and ebullience was the license you needed to drive oxen in Spain. For anyone who's trying to come up with an English corner idea, this seemed to work well. The idea is simply to get them talking fluently which they're all doing now. I've got some debate plans afoot but this will take more than a couple of hours of planning to make a success of it.

Weekend ramblings

We're back to a completely full schedule again with the first English corner since I arrived back from Japan. Work is still a little crazy with too many projects on the boil but I did get a chance to escape from the office for a bit this weekend.

It's a pleasure when the rather anonymous words on the screen turn into a real person and I finally met up with Kevin of Weifang Radish fame and his wife Jinjin of Weifang Radish fame, by proxy. A very enjoyable evening chatting with someone who has spent a good length of time in various parts of China and who's blog continues to be an interesting read. Lots of hints for places to try and visit in my remaining time here, too, though I fear spare time may not be in great supply.

There's been talk in the local papers of the rather infamous Sensations art show coming to Beijing's Capital Art Museum. Unfortunately, having read the papers I completely forgot which gallery it was to be shown at and ended up at a rather insipid exhibition at Beijing's World Art Museum of photographs of 'new Beijing' which was very uninspiring. They're currently also showing a display of Egyptian artwork with some fine sculpture but anyone who has been to the British Museum or the like is probably going to be rather unimpressed. In the basement is a carved mural of Chinese history which is worth a peak and the central golden columns are wonderfully gaudy, if nothing else.

World art museum
On the way to the train station I passed a young girl sitting idly in a chair overlooking the remains of the flats which had once sat where she now was. I found it rather more moving than any of the art on display at the museum.

artWALK Beijing

Next Saturday (21st of April) will see the second of Beijing's artWALK events which will be going back to the Dashanzi art district (see here for my first impressions of Dashanzi). This will include tours of several galleries, a chance to meet and talk with some of the movers and shakers of the Beijing contemporary art scene and a lot more besides. The website currently hasn't got so much information but I received the following after e-mailing for more details:

  • artWALK Beijing has invited the following 798 Dashanzi art district venues to participate on Saturday, April 21st : 798 Beijing Art Place, Anni Art, Dimensions Art Center, Xin Dong Cheng Space for Contemporary Art I & III, Marella Gallery, Red Gate/798 Gallery and Star Gallery. As part of its monthly lecture series in conjunction with artWALK, Timezone 8 Editions will also host a discussion with owner Robert Bernell, who will talk about the history of the 798 art district.
  • During artWALK there will be a few local acting troupes doing improve and outdoor theater. The cocktail reception will once again be at Yan Club although we're looking for new entertainment (the lovely Syndicate DJ's will be at a reggae gig that night over in Zub which would be great to go to as an after-artWALK party).
  • As always we're looking for volunteers (email elyse @ artwalkbeijing.com) and are constantly improving our website www.artwalkbeijing.com. artWALK beijing is a non-profit organization and runs on the donations and goodwill. We will be selling tee shirts at the April artWALK as a way of getting better funding, so (and sorry, I have to do my plug here) tell your friends. One of the t-shirt designs is the tiananmen picture you see when you visit www.artwalkbeijing.com, another is a robot design. There will be a total of five more artwalks after the April one. Three will be at 798 but two will move off location to farther locals such as the winery and caocangdi. We're looking to get shuttles for those trips as they are rather off the beaten path.
This looks like fun to me so if you're in Beijing and fancy coming along to see what's happening in one of the most vibrant art areas I've ever been to then pop along.

I've been told that the event will start around 6pm, though I haven't found any confirmation of this. I will be going earlier to wonder around some other galleries so anyone who wants to come along too and doesn't know Dashanzi should send me an e-mail.

Manatee endangerment issue

Time is scarce at the moment and I'd like to be able to look into this topic in more depth. It sounds like a worthy issue to be bought to light and for people to make an effort. Anyway having a mouth piece, if only a simple one, I will simply link to and tell you to read the article at Retrospectacle on the current push for the endangerment status of manatees in Florida to be downgraded so that people can whizz about on their boats a little faster.

Kurt Vonnegut 1922-2007, simultaneously

The news and blogosphere are awash with tributes and personal reflections on Kurt Vonnegut who died yesterday at the age of 84. There are a lot of interesting memories and quotations of a man I knew little about, other than what one learns reading Slaughterhouse Five. This is a moving, temporally warped story with perspective altering thoughts on time and memory, fatalism and humanity. The author of the book was clearly both a talented writer and a deep thinker. It's based on his almost unbelievable tale from Dresden where he was one of just 7 US prisoners of war to survive the firebombing, stuck as he was in the meat cellar of Slaughterhouse Five.

Many authors of the blogs I read are deeply into sci-fi and have some lovely and amusing stories of him. Read the posts from these blogs to learn a little more about this intriguing man who sadly past away: Bad Astronomy Blog, Pharyngula, Retrospectacle and NPR for some audio of and about Kurt.

Beijing blossom

I'm down with the cold that seems always to come, for me, soon after the heating in Beijing changes. It's warmed up considerably here over the last week and the heating has been turned off for the few hundred million households whose heating is controlled 'from above'. However, the insulation in my flat is not bad and as it heats up outside, even with the windows open the flat takes a while to warm up. So it's a bit too chilly and I'm now paying the price. Anyway, all very tedious and I'll be better in a day or two.

This weekend was the usual mixture of work and running around the city. On the way to meet some friends of the family I was shouted at by my taxi driver, twice! Once for drinking a mixture of Chinese tea and a Chinese cold remedy - a no-no, and once for not knowing how to get to my destination, although I gave the exact address and a description of the building. The first offense I thanked him for his advice but I have to admit that I laughed when he started chastising me for not knowing my way in the city.

Having been asked to find somewhere not too touristy to meet up with some friends of my family, we met up in one of my favourite tea houses. Although going for a tea ceremony is, perhaps, a touristy thing to do, it is at least a very relaxing way to spend an afternoon away from the crowds. The road leading to the Confucius Temple from Yong He Gong houses a few interesting restaurants including, so I'm led to believe, a rather fine all-vegetarian place. It also has an extremely peaceful, if tourist driven, tea house where for about 50 kuai (£4) per person you get a selection of teas which are refilled as long as you are happy to sit there letting the world rush by outside. They talk you through the method of preparation and will pick the teas to your taste. See here for a good breakdown of the basics of Chinese tea.

On the way back I took a few more snaps of the city which is now coming into bloom along with a few city life shots, here's one, but more can be found here.

Beijingers in the blossom 2

Anyway, while the cold levels are up, my concentration and productivity for work is down so I'm trying to spend some time reading up on a few topics while the current calculations are put on hold. Given enough vile tasting medicine I should be fighting fit in a day or two.

With seconds to spare

A few random links...

  • First to a site which I mentioned, perhaps a year ago, but is always worthy of a plug. There's big news in the Beijing music scene this month as Sonic Youth are due out here. The tickets are very expensive but I would love to go and see them, so will attempt to pick some up tomorrow. Pandora is one of the best resources I've found to discover great new music. By selecting a band or song to begin with, this online radio player choses songs based on the style of music from your original choice. By telling the station whether you like a particular track or not it will evolve to give you more and more of the type of music you really like. Listening to a station today seeded with Sonic Youth I've found a host of new bands I'd never previously heard of.
  • Discovery sites (Digg, Pandora, Stumbleupon, del.ici.ous Plime, and presumably many more) are becoming big business and allow the user to find web content based on what other people with similar tastes have liked in the past, rather than based on a specific web search. It's a powerful tool but also an easy way to fritter away time jumping from one interesting site to another, not taking anything of any real content in. It's definitely one of the many new branches of web technology which will be interesting to keep an eye on.
  • On a side note I wonder if anyone has tried to develop a community del.ici.ous site where papers from the ArXiv can be tagged for searching more appropriately than the current search functions available online. At the very least I would like my pdf files to be tagged with the basic information about each paper and not have to type it all into an unweildy title name.

  • While we're on the topic of the ArXiv I'll point to both the papers by Jacob Bourjaily (here and here )and the subsequent positive analysis by Lubos Motl. The papers are geometric engineering of F-theory (a 12 dimensional theory where the complex dilaton-axion of IIB string theory take on a geometric interpretation as the complex structure of a two-torus). The geometry of the compactified dimensions determines the symmetries and matter content of the low energy theory and so in these papers the standard model gauge groups and matter content are constructed via this process of geometric engineering, 'unfolding' from larger gauge groups.
  • Jacob shows that not only is a three flavour standard model a generic feature of a particular (and perhaps natural, from the string theory perspective) orbifold singularity but that smaller gauge groups are more natural from this construction than grand unified theories with large gauge groups. He points out however that the fact that the standard model symmetries aren't completely 'unfolded' is not obvious from this model.
  • Lubos gives a more thorough explanation although the general idea of the papers isn't too difficult to understand, even without knowing the background in great detail.
  • There was lots of news a couple of weeks ago about a huge calculation of the structure of an immense but important symmetry group. I'll just leave this as a series of links, if you want to read the maths there's some fascinating discussion at John Baez's site and if you just want to look at the pictures, well, they're pretty too. The American Institute of Mathematics has some details here, too.
  • The subsequent edition of This Week's Finds also contains a wealth of interesting material on solar flares plus more information about groupoids.
Apart from that I've been rather too busy calculating to read any new science over the last week or so.
  • From the BBC comes the news that the new wing of the Tate Modern has been given the go ahead. Without a doubt it's an exciting piece of art but it has a lot of critics who are not impressed. I like the look from the artist's impressions and the claim that London is becoming riddled with different styles of architecture is a century or so too late. The architects, Herzog and de Meuron, are also the designers behind the Beijing Olympic stadium - The Bird's Nest. I go past this whenever I go to the airport and would love to get there some time to take some photographs myself.
  • My parents recently came back from a trip to Paris where they took this rather fun picture:

This is an original image.

  • From Kevin at the Weifang Radish came some useful hints for internet use in China, definitely good if you want to keep up with blogs and news but don't want the lag of proxies.
Right, the weekend beckons and I have another few hours to work before I start running around the city again. Happy Easter to all...

Qing Ming Jie

Things have been completely non-stop, mostly with work this week to stop and think about blogging. In fact I've barely read any articles but there are a few things which are worth pointing to, which have come to my attention.

Yesterday was a festival day in China - Qing Ming Jie - clean and bright day. This is the day on which one is supposed to go and clean the tombs of your relatives, pay your respects at the temple and eat only uncooked food. In fact today a lot of the department is out at Fragrant Hills where the ashes of one of the great Chinese Academicians, who passed away earlier this year, are scattered. From Xiang shan you get this view of Beijing, if you're lucky:

The e-mail invitation was in Chinese so I am not there. However, it makes for a peaceful office.

The reason one goes about these rituals on this day are supposed to go back to a Tang dynasty story. While in exile, Chong Er, the disgraced son of the King, was saved by one of his men, Jie Zitui, who offered a chunk of thigh when the royal was about to starve to death. Though temporarily overwhelmed with gratitude, having been saved by a bit of broiled man leg, the prince promptly forgot about his savior and when he came to power gave many high positions to important persons but not to the man who had sacrificed his flesh for him. He later realized his omission and set about trying to find the man who by this time had taken to a hill with his mother, retreating from the world.

The emperor eventually found where he was but couldn't persuade the man to come down. Thinking he would be able to force him down he set alight to the mountain. However the man and his mother stayed steadfast and died in the flames. Leaving only a poem, wrapped in some cloth in the trunk of a tree. With regret the emperor proclaimed that everyone must remember Jie Zitui on that day and hence on Qing Ming Jie the Chinese remember the good man and his sacrifices, go to the graves of their relatives to give them a spring clean and don't cook the day before, in order not to start any fires.

Any Chinese experts know whether it's appropriate to wish Qing Ming Jie kuai le?

Basic resources for learning Chinese

I mentioned to a fellow blogger who is learning Mandarin that I would pass on the language resources I've found useful, but it seems sensible to make this list available to all.

I have a two hour lesson once per week, when work allows, and we use a book called Chinese Conversation 301. I have little to compare this book to but my impressions are that although it covers all the grammar needed and introduces about 15 new words per lesson, it's a bit drier that it needs to be. I tend to be rather fickle about these things and so without discipline I would simply flick from book to book, being a little dissatisfied with them all.

[Addition: Kevin mentioned his more extensive list of resources in the comments, which are definitely worth checking out here]

I would definitely advise getting a book on Chinese radicals if you're going to learn to read and/or write. A great deal of the complexity of the written language can be broken down when you understand the roots of many words and learning the 100 or so most often used radicals will give a good boost to the seemingly impossible task of learning characters. I have this book, and have found it to be very useful.

I haven't bought any yet but there are many kids books with lots of pictures of objects, animals, foods etc. with the Pinyin written by them. This is probably also a very good source for learning vocab by getting a rather more colourful image in your head.

ZDT is the best flashcard program I've found which allows the user to define several different modes to test yourself on Pinyin, English definitions and Hanzi (characters). There are also audio plugins so you can hear the words read by a Chinese reader. Importantly the format allows you to use word lists from several sources and there are a few which are well worth using, certainly for beginners, here.

Included in the word lists above is mention of the Pimsleur language lessons which I still use regularly and these are probably my best and, importantly, most hassle-free resource. The lessons are half and hour each and highly repetitive. I try and get through 5 or 6 of these lessons a week, though it wouldn't be a stretch to do much more as I potter around the flat or walk to work. I imagine this is the sort of thing you can get in most libraries in the UK and, I guess, in the US.

The Chinese pod lessons are also a useful resource though Pimsleur has taken over on the i-pod for me.

For Chinese dictionaries online I tend to use Zhongwen.com mostly because it has a useful interface for understanding the links between and roots of words. If it's not in this rather small dictionary then it usually gives an option to check several other dictionaries.

I added Laowai Chinese to my feed reader as soon as it started and although he tends not to post very frequently, this blog has had many interesting articles on different aspects of learning the language and I recommend taking a look and picking up a few words there.

Any other invaluable resources are welcomed in the comments section!

Spring cleaning tips

Though great plans were afoot over the weekend for various activities in the city it all fell through in the end in a fit of apathy and I ended up doing some much needed spring cleaning of the computer having scattered all the photos from Japan in a swathe of directories, some backed-up, some not, along with collections of papers and music in various degrees of replication. Anyway, this fact isn't so interesting but I found a couple of useful programs for anyone trying to consolidate files on their computer:

The first is Dump3 which can be used to find duplicate files on a computer by comparing the content, not the size and name, including music and picture files. You can set the criteria for a match manually allowing for similar but not exact copies of the same tune to be found. For pictures and music it takes a while but for pdf documents it's pretty snappy.

The second program is Foldersync which allows you to take two folders, searches for their differences and can copy and delete content accordingly. Useful if you have a backup of an old folder which has had a few changes made to it, including having changed the structure. These two programs together have let me get rid of a lot of duplicate files while making sure that I have everything backed up without replication.

Breath and stop

It's that time of year once again when the sky turns to ochre and you feel constantly like you're having a picnic on the beach. Each year the sand from the Gobi desert heads Beijing way, and beyond, last year getting far enough to hit Tokyo. This year apparently the Chinese meteorological association, in cahoots with the army have been seeding the clouds in order to try and limit the effects of the incoming cloud of dust. Though this has come to me only through complicated routes of hearsay it seems reasonable as we've been having rain for the last few weeks, whereas last year there was virtually no rain in Beijing for 6 months, give or take.

This weekend has been a respite for me as the last week was an intensive mix of research with my collaborator, new insights into the power of language and me giving a rather last minute talk. I took the opportunity to give the talk (on heavy quark potentials in AdS/QCD) as a blackboard talk, my first talk of this kind and something which I can see takes both careful planning and practice.

I spoke for a little over an hour from a few sheets of notes and though I hope I got the general idea across, this is clearly something I need more practice at. I've been asked to give a couple of review lectures on AdS/QCD at an upcoming workshop in Beijing so may take this as another chance to use this technique which, when used appropriately, can produce very effective presentations. In particular this is because the pace is automatically slowed. The chance of large equations, which rarely elucidate a problem in a seminar, is small, and it makes the whole process a more active one for all involved.

I still have numerous projects on the go but hope to post up a few things of note over the coming days.
