Women and collective intelligence

From Defend Your Research: What Makes a Team Smarter? More Women
"The finding: There’s little correlation between a group’s collective intelligence and the IQs of its individual members. But if a group includes more women, its collective intelligence rises."

The Telegraph reviews "River of Smoke"

River of Smoke by Amitav Ghosh: review:

"His taste for obscure words aside, Ghosh can be a rather ponderous storyteller. Far too much of the book is taken up by windy letters from an English painter. But there are some nice comic touches, mainly involving characters talking pidgin English, and moments of real lyricism.

Best of all, Ghosh, through the depth of his research, lightly worn, has captured the many cross-currents of a fascinating historical period."

His "In an Antique Land" is one of the best books I read and I liked much of his non-fiction that I read. But I thought that his "The glass Palace" is a soap opera and this type of historical fiction seems to be a bit of cop out, which does not allow much discussion. I think that I will skip this book.

Dreaming of cancer

Recently on the way back from USA I was stuck in San Francisco airport for two nights, the first night because I did not check the times carefully and the second night because of United Airlines computer problems. It gave me chance to finish Siddhartha Mukherjee's excellent book " The Emperor of All Maladies: A Biography of Cancer" and now I imagine that I have precancer conditions. May be I will give up smoking now. In any case, I am back home to celebrate my 70th birthday today.

A comment in the post 'Academic Writing' by Amitava Kumar

From a comment in Academic Writing:
"A couple of years ago, I sent this as a puzzle to my colleagues in a course with a reading from Partha Chatterjee:

“The illusion of normative values is consistent with the legitimation of the nation-state. The logic of civil society carries with it the ideology of agency. Rival conceptions of collective identity have become implicated in rival claims to autonomous subjectivity, and the reification of capitalist hegemony opens a space for the historicization of the nation-state. The emergence of history as such functions as the conceptual frame for the politics of power.”

One or two sentences are from Chatterjee’s Nationalist Thought. The rest are generated from the U of Chicago Automatic Sentence Generator. No one guessed the auto-generated part correctly."

M.F. Husain RIP

One of India's most famous artists, MF Husain, has died in hospital in London aged 95 after years of self-imposed exile. For 15 years, I used to see his paintings almost daily in TIFR, Bomay (now Mumbai).

Farmer Networks in Mexico

From Farmer Networks Hold Key to Agricultural Innovation in Developing Countries, Study Finds:
"In Yaqui Valley, credit unions hold sway among the majority of farmers, McCullough said. In addition to providing loans, crop insurance, fertilizer and seed, credit unions have taken over the government's role in providing technical expertise and management advice.

Valley growers also have a long history of working with the Mexico-based International Maize and Wheat Improvement Center, a world-renowned agricultural research center known by its Spanish acronym, CIMMYT.

But interviews conducted for the PNAS study revealed that most farmers take their cues from local credit unions and not from experts at CIMMYT. As an example, McCullough pointed to a collaborative effort between CIMMYT scientists and farmers to develop a nitrogen diagnostic tool that reduces fertilizer use without sacrificing crop yields.

The device, which gives real-time readings of nitrogen levels in the soil, proved early on that it could save farmers 12 to 17 percent of their profits. Yet most farmers rejected the new technology until CIMMYT researchers finally convinced credit union officials that it was a worthwhile investment.

"The most successful innovations that have been adopted by farmers in the Yaqui Valley have come from collaborations among researchers, farmers and local establishments, like the credit unions," McCullough said. Because of their considerable influence among farmers, credit unions should be included in any effort to effect environmental change in the region, she added."

New experiment on Casimir effect

From First Observation of the Dynamical Casimir Effect :
""One of the most surprising predictions of modern quantum theory is that the vacuum of space is not empty. In fact, quantum theory predicts that it teems with virtual particles flitting in and out of existence."

So begin Christopher Wilson from Chalmers University in Sweden and friends in their marvellously readable paper about a rather extraordinary piece of science.

This maelstrom of quantum activity is far from benign. Physicists have known since 1948 that if two flat mirrors are held close together and parallel with each other, they will be pushed together by these virtual particles.

The reason is straightforward. When the gap between the mirrors is smaller than the wavelength of the virtual particles, they are excluded from this space. The vacuum pressure inside the gap is then less than outside it and this forces the mirrors.

This is the static Casimir effect and it was first measured in 1998 by two teams in the US.

But there is another phenomenon called the dynamical Casimir effect that has never been seen.

It occurs when a mirror moves through space at relativistic speeds. Here's what happens. At slow speeds, the sea of virtual particles can easily adapt to the mirror's movement and continue to come into existence in pairs and then disappear as they annihilate each other.

But when the speed of the mirror begins to match the the speed of the photons, in other words at relativistic speeds, some photons become separated from their partners and so do not get annihilated. These virtual photons then become real and the mirror begins to produce light.

That's the theory. The problem in practice is that it's hard to get an ordinary mirror moving at anything like relativistic speeds."

Travelling for a while

Off to USA tomorrow to attend a conference in honour of a collaborator on the occasion of his 65th birthday; a person who reminds of K.L. Krishna who retired from Delhi School of Economics a few years ago. Will use this opportunity to visit a few friends and relatives on the east coast.

Razib Khan responds to Edge question 2011 WHAT SCIENTIFIC CONCEPT WOULD IMPROVE EVERYBODY'S COGNITIVE TOOLKIT? with a quote from John Ioannidis "There is increasing concern that most current published research findings are false....."

With that proviso here are some research reports that I found interesting.

Artificial Grammar Reveals Inborn Language Sense, Study Shows

Language Log in Let me count the ways has a quote of Cosma Shalizi which echoes Razib Khan's worries: "While perhaps not a truly epic fail, this is not a creditable performance. The paper probes a hugely complex tangle of issues relating individual minds, communication, social norms, artistic expression, social change and cultural transformation. There is no shame in not unraveling the whole snarl at once, but between the incompetent data analysis, the failure of logical imagination, and the deep misunderstanding of how works of art are made and used, it does nothing to advance our knowledge of anything."
