Civil society and its concerns

Civil society has been much in the news recently, thanks to the Lok Pal bill, Anna Hazare, Baba Ramdev and the rest. Members of the civil society have been, perhaps justifiably, taking pride in the fact that they have been successful in making their voices heard. Therefore, this seems to be a good point to discuss who actually constitutes civil society, and more importantly, who does it in effect, exclude, and how does the composition of civil society affect its concerns.

To argue this out, it is necessary to identify who is excluded from this collection. To take a few examples, the urban working class, the rural population, the middle and lower ends of the caste hierarchy, and for that matter, the political class, all clearly do not belong to the conglomerate defined above, and have an entirely different agenda. As a simple example of this, it is hard to imagine that the excluded collection would have the kind of interest in the joint entrance exam of the IIT-s that the included fraction does. After all, only about four lakh students take the entrance examination every year, out of our population of one billion plus (it's pointless even to discuss the statistical significance of the 16,000 who actually get in), however, discussions of the entrance exam, however well argued or otherwise, occupy an entirely disproportionate amount of newspaper space, as compared to the concerns of the dispossessed.

So what should civil society do? Maybe it could broaden its outlook. Its current agenda may be all right, but it is narrow, and might even turn out to be self-serving (any bets on which class of society the Lok Pal will come from, if ever we get one?). It is a pity that the agenda of the elite leaders of society is so limited. There was a time when this was not so, and the leaders of civil society looked outwards to the requirements and aspirations of the entire country, and not just to those of people like themselves. This time was before independence, when the elite spearheaded both social reforms, and political movements, and managed to carry the country with themselves. Is it a pipe dream to hope that such a time will come again?

Confession: This blog post was inspired by a recent article by P. Sainath in the Hindu. Do see the article. The Reds do occasionally get something right, especially on issues which are not of any interest to Beijing, and hence do not come with any predefined policy!

Things that go bump in the data, and live computing

It is time to report again on the bump in the Tevatron data at Fermilab. In April, Fermilab had reported that there was an unexpected bump in the total number of events that produce a W boson and two jets. This bump could not be explained by the standard model. The data was greeted with enthusiasm by some model builders, who rushed to build theories, and scepticism by others, who pointed out that it could be explained by a simple miscalibration of jet energies. However, it was universally agreed that the effect, which was a 3-sigma effect, needed further data before it could be supported or dismissed. Well, further data is now in from the CDF experiment at Fermilab, and the effect hasn't gone away. Instead, it is now a 5-sigma effect (well, 4.8-sigma, if you want to be picky). While the hard headed await further data from other sources like the LHC, phenomenologists have not found it too hard to come up with models that account for the bump. Some of the attempts include the proposal of a new vector boson Z', that needs to be leptophobic (i.e. not decay into leptons, but only into quarks). Aficionados of supersymmetry have come up with a sbottom decaying into a stop, but there are numerous other contenders. Here are the references for the technically inclined.

Theorists versus the CDF bump;

CDF: Wjj bump almost 5 sigma!!!

Meanwhile, at the other end of the spectrum, researchers at Caltech have managed to manipulate strands of DNA into computing a square root. There's a really cute video at

DNA takes square roots

It looks like there are exciting times ahead for scientists of varied interests. It makes for a pleasant change from the days of the doldrums.

Update (11/06/11): Whoops! This is a real roller-coaster ride. The D0 data at the Tevatron, now finds no bump at the earlier reported energies. More info on this when it comes out.

(12/6/11) Here is the way it pans out, as of today. The CDF data shows a clear bump in the distribution of events in the neighbourhood of 150 GeV. The D0 data, carrying out similar analysis shows no bump in this range. The clearest discussion that I found of this is here. The rest awaits further data and analysis.

Three ladies

The first two require no guesswork: Jayalalitha and Mamatadidi. Everyone is writing/blogging/tweeting about them. Here's a link or two to some recent posts about them.

The women who rule India;

`Amma,' `Didi' to double the number of women CMs.

The third one may come as a bit of a surprise. This is Jane Goodall, the celebrated primatologist, in the news this week for having two children's books written about her. Her pathbreaking studies in primatology started with a childhood gift from her father, a toy chimpanzee called Jubilee. Goodall is best known for her studies of the social behaviour of chimpanzees. She lived among the chimpanzees in Gombe National Park in Kenya, and is credited with the first observations of tool making in non-human primates, and for exploding the belief that chimpanzees were vegetarians. She also observed evidence of mental traits like reasoning, abstraction, symbolic representation and a sense of self among chimpanzees, which had been thought to be unique to humans upto that point. Jane's studies were criticised for not following the strict, impersonal norms of primate studies which were followed at that point, like giving names to the chimpanzees she observed, instead of numbers, as was thought to be more `objective'. This lack of `objectivity' was supposed to contribute to the `anthropomorphic' conclusions of her study. However, many of her conclusions have been validated by other studies.

In a recent interview, Dr. Goodall was asked a question on what she thought were the reasons for which women, by and large, stayed away from scientific careers. To paraphrase loosely, she said that this might be because science was thought to be a career where empathy and intuition, two traits which she said were pronounced in girls, were squashed out in favour of coldness which was equated with objectivity. She also said that scientists should be human beings first, and scientists next, and empathy and intuition should be taken advantage of, and the conclusions drawn using these traits should be tested out in the light of rationality. This is a truly unique message and surely worth thinking about.

Quote of the week: `If you have a dream as a child, follow it even if people laugh at you for it, as they laughed at me.'- Jane Goodall.

An ode to the west wind

Today marks the birth anniversary of one of India's most illustrious sons. Rabindranath Tagore was born on May 7th, 1861, a hundred and fifty years ago. The newspapers have written reams about his poetry, his novels, his world view, and his impact on the world. This post is about a very tiny aspect of his personality and genius, namely, the impact of western music on Tagore and how it influenced some of his work.

Most Bengalis are aware that Tagore was inspired by old English, Scottish and Irish tunes in his youth - the poet admitted as much himself. Such songs are termed bilāti-bhāngā gān. Tagore went to England at the impressionable age of seventeen, and heard the tunes of Irish melodies and Scottish reels. He returned full of high spirits and began composing songs for the evening entertainments that were a regular feature of his ancestral home; and many of these songs were inspired by his musical experiences abroad.

Tagore first used bilati airs immediately after his return from England in 1881 in the musical Vālmīki Pratibhā which narrates the metamorphosis of Ratnākar, a formidable bandit king, to Vālmīki, legendary poet-sage who wrote the Rāmāyaņa. Of this work, Tagore himself said `the tunes in this musical drama are mostly Indian, but they have been dragged out of their classic dignity; that which soared in the sky was taught to run on the earth. Those who have seen and heard it performed will, I trust, bear witness that the harnessing of Indian melodic modes to the service of the drama has proved neither derogatory nor futile.' Many of the tunes of this play were composed by Rabindranath's brother Jyotirindra. Two of the songs in the play were set to `English' tunes, viz. `Nancy Lee' by Michael Maybrick (who composed as Stephen Adams) and `John Peel'. `Nancy Lee', a rousing sea shanty in the original, metamorphosed to an invocation to the Goddess Kālī that the bandits sing in the forest in Tagore’s version.`D'you ken John Peel', a popular hunting song, has been surmised to inspire the song ‘tobé āy shobé āy’, of Valmiki Pratibha, which is similar in both melody and spirit.

Soon after this, Tagore stopped using bilāti tunes in his songs. Instead, the stream of ideas trickled underground, to emerge in his mature years in his great song offerings in the Gitanjali. Tagore's poems and music managed to break free of the rigidities of the classical Indian forms and achieved a brilliant fusion of both Indian and western sensibilities, and made him the Gurudev that we commemorate today.

This post is by Srovonti Basu Bandopadhyay. Srobonti is an accomplished Rabindra Sangeet singer. We hope to see her, her husband Arindam, and their friends, perform these songs one of these days. Incidentally, Srovonti is Rahul's cousin. -Neelima.

Tere bin laden (and millinery too)

Just so as not to be the only blog that hasn't mentioned the topic of the week, here is a slightly skewed take on Osama bin Laden and his death. There will be arguments ad infinitum on whether bin Laden's death really changes anything, and whether Pakistan first concealed his whereabouts and then threw him to the wolves when the U.S. made things too hot; to say nothing of whether U.S. policy towards states which sponsor terrorism will change after this. This post is only to admire the classic intelligence legwork and tailing of small fry which led to the discovery of Osama's hiding place. It is to be hoped that no part of this success will get tainted by identification with the inhuman interrogation techniques of Guantanamo Bay (although one can't be sure at this point). If not, George Smiley would surely rejoice!

On the topic of last week, namely, the Will-Kate wedding, what hats!

A starchild and the stuff of stars

This week has been notable for two reasons, one for what it reminds us of that's past, the other for what it might bring in the future. It's fifty years since Yuri Gagarin blasted off into space in Vostok 1, on April 12, 1961, opening up a new era in exploration and human endeavour. He spent an hour and forty-eight minutes in flight and completed one orbit round the world before re-entry, ejected from his capsule and landed by parachute. The world goggled at this smiling, handsome superman (only five foot two, by the way, an inspiration to shorties) who stole the thunder from Alan Shepard who blasted off into space just about three weeks later. This is also a good place to remember the brave dog Laika, who was sent up in space four years earlier, with no expectation of her ever coming back. There are those who will argue that the thing to remember is the Sputnik programme, which launched the space era, the Cold war, and on the plus side, a whole generation of Sputnik kids into science.

This ushers in the second half of today's post. A recent analysis of the data collected at the Tevatron, the accelerator at Fermilab, shows what might be signature of a new particle, not predicted by the Standard Model (the established and accepted model for all elementary particles observed so far). The physicists are cautious, as the data is still not of the confidence level that declares a new particle and new physics. However, the buzz is around, and phenomenologists (the model builders) are licking their lips. More on this, if the bump in the distribution survives further data.

Tailpiece: A new song on Yuri Gagarin, tentatively called starchild, is being recorded by someone who is more than qualified to record a song like this. This is Brian May, who left incomplete a Ph.D. in astrophysics to become a guitarist for the rock group Queen. Incidentally, he finished his Ph.D., with a bona-fide thesis, on, as it happens, stardust, thirty years later.

Ud gaya hans akela

With deep regret, we announce the sad and untimely demise of Rahul Basu, the writer of this blog, on 5th March 2011. He came down with a serious respiratory infection in December, but was recovering well. However, a sudden relapse took him away from us, his sorrowing friends and family.
His non-blogging persona was that of a particle physicist. Many aspects of his professional and public persona have been described by his friends and colleagues on the beautiful memorial page put up by his institute, the Institute of Mathematical Sciences. He was quite different with his close friends and family. He was playful and affectionate, and enfolded those he loved in his tender care. Now he is gone, and we are bereft. However, we plan to continue this blog in his loving memory, with help from all his friends, and members of his family.
We hope you will read your blog, Rahul.

Ud jaayega hans akela
 jag darshan ka mela
 jaise paat gire taruvar se
milna bahut duhela
na jaane kidhar girega
lageya pawan ka rela
jab howe umar puurii
 jab chhuutegi hukum hujuurii
Yama ke doot bade mazboot
 Yama se pada jhamela
 Daas Kabir Hari ke guna gaawe
woh Hari ko paaran pawe
 Guru ki karni guru jayega
 chele ki karni chela
Ud jaayega hans akela
jag darshan ka mela...

(Kabir Bani-Sant Kabir.)

The swan will fly away all alone
the world will merely be a spectacle like a fair
As the leaf that falls from the tree
is difficult to find
 who knows where it will fall
 once it is struck with a gust of wind
 when the span of life is complete
then obeying orders, following others, will be over
The messengers of Yama are very strong
the tangling had to be with Yama
the servant Kabir praises the attributes of the Lord
he finds the Lord soon
the Guru will go according to his doings
the disciple according to his
 The swan will fly away all alone ........

(Thanks, Jogesh, for the Kabir bhajan and the Kumar Gandharva reference.)
