Shomu Banerjee has learned lessons in how to lead a contented life through encounters with all kinds of people, from an Indian road worker he sat next to on a bus to a Nobel Laureate in economics who was his graduate school advisor.
What can economics, "the dismal science,” teach us about happiness?
Plenty, says Shomu Banerjee. A senior lecturer and applied microeconomic theorist at Emory, Banerjee was a presenter for the university’s recent Good Life Speaker Series.
“Happiness is related to our perspective, the way we choose to look at things,” he said in his talk. “And the definition of economics in this day and age is the study of choice: How do people choose things, how do they make decisions.”
He recalled an experience he had while walking on the Emory campus, when he noticed a woman in her early 30s standing at a bus stop and crying.
“She had tears flowing from her eyes and there were all these people standing around and nobody was saying anything to her,” Banerjee said. “I said, ‘Is there anything I can do for you?’ And she said, ‘No, it’s okay, thank you very much.’ And then she said, ‘You know, one day I’m going to look at this and laugh.’ So I said, ‘If you already know you’re going to look at this and laugh one day, why not start right now?’ And she did actually start laughing at that point.”
Once your basic needs are met, such as food, water and shelter, happiness becomes more about choice and perspective, and finding ways to create meaning in your everyday life, Banerjee said.
Banerjee, who was born in England, described his family as “pretty poor.” He grew up in Pakistan, Madagascar and Turkey, with occasional stints in India, before moving to the United States at 21.
The Crab Nebula is the remnant of a supernova recorded by
Chinese astronomers in 1054, located 6,500 light years from Earth with a
diameter of 11 light years. “It’s massive,” says Banerjee. “When you look
at it, you realize how ephemeral our lives are and how we really shouldn’t agonize
over the small, irrelevant things in life.”
“When I came to the United States, the thing that I wasn’t ready for was what a cold place this was in terms of relationships, relative to what I’d been exposed to,” he recalled.
Outside of primary relationships, he said, many people seem to consider their relationships as transactional, like the market environment that imbues so much of society. He urged students to go beyond the transactional and take the time to notice others and empathize with them.
Banerjee recalled a story from his college years in India. He had boarded a bus with no empty seats. He stood next to a seated man who was obviously a road worker.
“Road workers worked with their hands and wore turbans to carry baskets of dirt. Their fingernails would be caked with mud,” Banerjee said. “Maybe this man saw the tired look on my face. He scoots up on his seat, makes a little space and says, ‘Sit down here.’”
The man had been sweating and was covered in grime from a day of labor in the hot sun. Banerjee hesitated. He politely declined the man’s offer to squeeze in next to him, giving the excuse that he didn’t want to crowd him.
“The man told me, ‘If there is space in your heart, then there is space here,’” Banerjee said. “Now this came from a man who is probably totally illiterate. I went into automatic mode and sat down. I wasn’t even thinking. This is what I mean by empathy. These things do make a difference in the quality of our lives, but we tend to forget how to relate to others.”
Watch the video of the talk by Shomu Banerjee:
Another key to happiness is choosing not to compare one’s self to others, Banerjee said. He told a story from his graduate school years: “I had a wonderful PhD advisor, Leonid Hurwicz, a Polish-American economist who won the Nobel Prize in 2007. He was Jewish, part of his family died in the Holocaust, but he never talked about those things, ever. Except this one time.”
When a faculty member came up for tenure, and Hurwicz was asked to rank the candidate next to other luminaries in the field, he told Banerjee: “How can I compare people, and say that this person is as good as A or not as good as B? I cannot do that. And more than that, I refuse to do it, because that was the kind of madness that the Nazis were engaged in.”
Banerjee encouraged students to choose to do things that they love, rather than search for direction by browsing the marketplace. “That’s appropriate for grocery shopping,” he said, “but for living I think it’s far more important to ask, ‘Who am I? What lights me up? What motivates me? Rather than just go from classroom to classroom or major to major, shopping.”
He also advised them to make a list of simple activities that nurture their spirits and to do these things from time to time. He recalled feeling overwhelmed when he was a graduate student working on his thesis, and how he would escape that feeling by sitting beneath a tree to feed the campus squirrels.
“The challenge was getting them to actually eat out of my hand,” he said. “For those 10 to 12 moments that I was trying to feed the squirrels, I was really enjoying this inter-species interaction. I was in the moment. I was not thinking about, ‘If I don’t get my thesis I’ll have to go back to India with my tail between my legs.’”
Banerjee still makes time for activities to nurture his spirit. “Last year, around Thanksgiving, my daughter and I climbed Stone Mountain early in the morning,” he said. “We went up in the dark and watched the sun rise. It kept me going for months. It really filled me with joy. I don’t know why. Maybe it connected me with my human ancestors who looked at the sun and didn’t know what it was and were totally amazed. But I was equally amazed in the 21st century. It’s the beginning of a day, so much promise, all those things that make me feel happy.”
Many students who come to him for advice do not have a strong calling, Banerjee said. One of the hardest decisions they have to make is what to do with themselves.
He offered a quote by the late Howard Thurman, an African-American civil rights leader, who said: “Don’t ask what the world needs. Ask what makes you come alive, and go do it. Because what the world needs is people who have come alive.”

What smart animals are teaching scientists
“Up until a million years ago, the brainiest species were dolphins and whales,” says Lori Marino, an Emory neuroscientist who studies these marine mammals. “We are just a very recent kid on the block.”
Marino is featured in a new NOVA series called “Inside Animal Minds,” which is exploring what makes an animal smart.
“The six million dollar question is how dolphins and whales got such large brains,” says Marino, who is examining fossil skulls for clues about how complex cognition involved in cetaceans.
Research into many species is showing that animals may be more like us than we ever thought possible.
Other Emory scientists featured in the series include primatologist Frans de Waal and neuroscientist Gregory Berns, who is researching the minds of dogs through the use of fMRI. Emory graduate Brian Hare, who is exploring the canine brain through behavioral studies, is also part of the series.

Are you a thrill seeker or a chill seeker? Join a psychologist's survey
"I don't want people to think that sensation seeking is a psychological disorder at all, but it can be linked to or exacerbate certain situations," says psychologist Ken Carter.
By Elaine Justice, Emory News Center
Whether you're a thrill seeker, or someone who'd rather be safe than sorry, clinical psychologist Ken Carter is looking for you. Carter, professor of psychology at Emory's Oxford College, is casting a wide net in gathering research for an upcoming book project on "high sensation seeking" people.
He's looking for people to visit his website, buzz.drkencarter.com, where they can complete a brief survey showing how much of a "sensation seeker" they are. The survey is a modified version of a sensation seeking scale personality test developed in the 1960s by Marvin Zuckerman of the University of Delaware. Zuckerman says that sensation seeking is "a personality trait expressed in behavior as a tendency to seek varied, novel, complex and intense sensations and experiences and to take physical risks for the sake of having such experiences."
Know anyone like that? One of the things Carter noticed in some of his friends, his clients and some of his students, too, is that there seem to be certain people who tend to have more chaotic lives than others. "I didn't know how much of that they were creating themselves or whether they just happened into these situations," he says. "I thought about them as 'chaos junkies,' as people who loved a chaotic life, who feed off that chaos. The concept of sensation seeking seemed to explain what I was seeing."
While there are people who get their thrills from really high sensation seeking activities, "it doesn't have to be jumping off a building or sky diving," says Carter. He cites the example of fire fighters or police officers, who have fairly routine activities during long stretches, punctuated by very high sensation activities that are part of the job.
The sensation seeking test shows an overall score as well as sub-scores in four areas: thrill and adventure seeking, experience seeking, dis-inhibition, and boredom susceptibility.
"Different people can be high or low on different parts of the overall concept," says Carter, "and the high sensation seeking person can look very different in different situations." Carter says he plans to use not only the sensation seeking test results but people's stories as well. "When I did a workshop on sensation seeking recently, people's eyes light up, because they either know someone like this, or they themselves are like this," he says.
A psychologist approached Carter after the workshop and said he was an introverted high sensation seeking person. "You'd think that introversion and high sensation seeking would be an oxymoron, but introversion has a lot to do with being in your head and recharging yourself by being alone," says Carter. "There are high sensation activities you can do alone, such as rock climbing, which an introvert would really enjoy."
Carter says one of the great things about using social media to gather research material is that it gives him the ability to test his ideas and find out what's interesting to audiences before publishing the final product. Those wishing to share their stories can do so on Carter's Facebook page, and can follow him (@drkencarter) on Twitter as well. "I'm looking forward to collecting people's stories and experiences," he says. "For instance, sensation seeking tends to decrease as we get older, so I'm curious to see how individuals who were high sensation seeking when they were younger change as they get older."
His book is intended for three audiences and purposes: as a compendium of research on sensation seeking for academics; as a resource for counselors and therapists; and as an information tool for the public. For therapists, more information on sensation seeking could help them help clients. "Some people may seem to have attention deficit hyperactivity disorder (ADHD) or be bipolar, but what it really may be is high sensation seeking, which requires a very different kind of intervention than a psychological disorder might."
"I don't want people to think that sensation seeking is a psychological disorder at all, but it can be linked to or exacerbate certain situations," says Carter. "I want to explain to people what this concept is, how them how it can manifest itself in different ways, but also help them get the most out of that awareness." For example, "some research indicates that people who are high sensation seeking have lower levels of stress and anxiety, that there's a protective factor for them," says Carter.
"You'd think they'd be more stressed out, but apparently they can tolerate a lot more chaos." While lower sensation seeking people may be more easily thrown off base, says Carter, "high sensation seeking people can more easily roll with the punches, so there are some great aspects of it, too."

The art and physics of falling fluid
Pouring layers of paint, of different colors, produces “the most magical fantasies and forms that the human mind can imagine,” wrote Mexican painter David Alfaro Siqueiros.
It turns out that Siqueiros and Jackson Pollock, two iconic artists of Abstract Expressionism, were also experimentalists of fluid mechanics.
“Physical analysis illuminates the ways that both artists used a natural effect – fluids falling under gravity – to produce their works,” writes Emory physicist Sidney Perkowitz, in a recent issue of Physics World.
The video above demonstrates that the patterns produced by Siqueiros, who described his technique as “accidental painting,” result from a Rayleigh-Taylor instability of a viscous gravity current.

Mathematicians trace source of Rogers-Ramanujan identities, find algebraic gold
By Carol Clark
Mathematicians have found a framework for the celebrated Rogers-Ramanujan identities and their arithmetic properties, solving another long-standing mystery stemming from the work of Indian math genius Srinivasa Ramanujan.
The findings, by mathematicians at Emory University and the University of Queensland, yield a treasure trove of algebraic numbers and formulas to access them.
“Algebraic numbers are among the first numbers you encounter in mathematics,” says Ken Ono, a number theorist at Emory “And yet, it’s surprisingly difficult to find functions that return them as values in a uniform and systematic way.”
Ono is the co-author of the new findings, along with S. Ole Warnaar of the University of Queensland and Michael Griffin, an Emory graduate student.
Ono announced the findings in April as a plenary speaker at the Applications of Automorphic Forms in Number Theory and Combinatorics conference at Louisiana State University. He will also present them as a plenary speaker at the 2015 Joint Mathematics Meetings, the largest mathematics meeting in the world, set for January in San Antonio. Warnaar, Griffin and others will give additional talks on the findings during an invited special session to accompany Ono’s plenary address.

| Ramanujan had "a Midas touch." |
The most famous algebraic number of all is the golden ratio, also known by the Greek letter phi. Many great works of architecture and art, such as the Parthenon, are said to embody the pleasing proportions of the golden ratio, which is also seen in beautiful forms in nature. Mathematicians, artists and scientists, from ancient times to today have pondered the qualities of phi, which is approximately equal to 1.618, although its digits just keep on going, with no apparent pattern.
“People studied the golden ratio before there was a real theory of algebra,” Ono says. “It was a kind of prototype for algebraic numbers.”
Although no other algebraic units are as famous as the golden ratio, they are of central importance to algebra. “A fundamental problem in mathematics is to find functions whose values are always algebraic numbers,” Ono says. “The famous Swiss mathematician Leonhard Euler made some progress on this problem in the 18th century. His theory of continued fractions, where one successively divides numbers in a systematic way, produces some very special algebraic numbers like the golden ratio. But his theory cannot produce algebraic numbers which go beyond the stuff of the quadratic formula that one encounters in high school algebra.”
Ramanujan, however, could produce such numbers, and he made it look easy.
“Ramanujan has a very special, almost mythic, status in mathematics,” says Edward Frenkel, a mathematician at the University of California, Berkeley. “He had a sort of Midas touch that seemed to magically turn everything into gold.”
And the Rogers-Ramanujan identities are considered among Ramanujan’s greatest legacies, adds Frenkel, a leading expert on the identities.
“They are two of the most remarkable and important results in the theory of q-series, or special functions,” says Warnaar, who began studying the Rogers-Ramanujan identities shortly after he encountered them while working on his PhD in statistical mechanics about 20 years ago.
Although originally discovered by L. J. Rogers in 1894, the identities became famous through the work of Ramanujan, who was largely self-taught and worked instinctively.
The Rogers-Ramanujan identities are among Ramanujan's greatest legacies.
In 1913, Ramanujan sent a letter from his native India to the British mathematician G. H. Hardy that included the two identities that Rogers discovered and a third formula that showed these identities are essentially modular functions and their quotient has the special property that its singular values are algebraic integral units. That result came to be known as the Rogers-Ramanujan continued fraction.
Hardy was astonished when he saw the formulas. “I had never seen anything in the least like this before,” Hardy wrote. “A single look at them is enough to show they could only be written down by a mathematician of the highest class. They must be true because no one would have the imagination to invent them.”
“Ramanujan seemed to produce this result out of thin air,” Ono says.
Ramanujan died in 1920 before he could explain how he conjured up the formulas. “They have been cited hundreds of times by mathematicians,” Ono says. “They are used in statistical mathematics, conformal field theory and number theory. And yet no one knew whether Ramanujan just stumbled onto the power of these two identities or whether they were fragments of a larger theory.”
For nearly a century, many great mathematicians have worked on solving the mystery of where Ramanujan’s formulas came from and why they should be true.
"Ramanujan has a very special, almost mythic, status among mathematicians," says Frenkel. Above is a still photo from an upcoming film, "Ramanujan," a biography of the math genius by Camphor Cinema.
Ono uses the analogy of going for a walk in a creek bed and discovering a piece of gold. Had Ramanujan accidentally found a random nugget? Or was he drawn to that area because he knew of a rich seam of gold nearby?
Warnaar was among those who pondered these questions. “Just like digging for gold, in mathematics it’s not always obvious where to look for a solution,” he says. “It takes time and effort, with no guarantee of success, but it helps if you develop a lot of intuition about where to look.”
Finally, after 15 years of focusing almost entirely on the Rogers-Ramanujan identities, Warnaar found a way to embed them into a much larger class of similar identities using something known as representation theory.
“Ole found the mother lode of identities,” Ono says.
When Ono saw Warnaar’s work posted last November on arXiv.org, a mathematics-physics archive, his eyes lit up.
“It just clicked,” Ono recalls. “Ole found this huge vein of gold, and we then figured out a way to mine the gold. We went to work and showed how to come full circle and make use of the formulas. Now we can extract infinitely many functions whose values are these beautiful algebraic numbers.”
“Historically, the Rogers-Ramanujan identities have tantalized mathematicians,” says George Andrews, a mathematician at Penn State and another top authority on the identities. “They have played an almost magical role in many areas of math, statistical mechanics and physics.”
The collaboration of Warnaar, Ono and Griffin “has given us a big picture of the general setting for these identities, and deepened our theoretical understanding for many of the breakthroughs in this area of mathematics during the past 100 years,” Andrews says. “They’ve given us a whole new set of tools to be able to attack new problems.”
“It’s incredibly exciting to solve any problem related to Ramanujan, he’s such an important figure in mathematics,” Warnaar says. “Now we can move on to more questions that we don’t understand. Math is limitless, and that’s fantastic.”
