“Since at least the time of Greek philosophers, many writers have discovered a deep, intuitive connection between walking, thinking, and writing,” says Ferris Jabr at the New Yorker.

Charles Dickens kept few notes about where his plots were headed. From what I’ve read about him, he kept it all in his head, forming and saving his ideas on long walks wherever he was at the time.

In today’s article, we learn a bit about the science of that.

Ferris Jabr writes, “In Vogues 1969 Christmas issue, Vladimir Nabokov offered some advice for teaching James Joyce’s Ulysses: ‘Instead of perpetuating the pretentious nonsense of Homeric, chromatic, and visceral chapter headings, instructors should prepare maps of Dublin with Bloom’s and Stephen’s intertwining itineraries clearly traced.’ He drew a charming one himself. Several decades later, a Boston College English professor named Joseph Nugent and his colleagues put together an annotated Google map that shadows Stephen Dedalus and Leopold Bloom step by step. The Virginia Woolf Society of Great Britain, as well as students at the Georgia Institute of Technology, have similarly reconstructed the paths of the London amblers in Mrs. Dalloway.

“Such maps clarify how much these novels depend on a curious link between mind and feet. Joyce and Woolf were writers who transformed the quicksilver of consciousness into paper and ink. To accomplish this, they sent characters on walks about town. As Mrs. Dalloway walks, she does not merely perceive the city around her. Rather, she dips in and out of her past, remolding London into a highly textured mental landscape, ‘making it up, building it round one, tumbling it, creating it every moment afresh.’

“Since at least the time of peripatetic Greek philosophers, many other writers have discovered a deep, intuitive connection between walking, thinking, and writing. … ‘How vain it is to sit down to write when you have not stood up to live!’ Henry David Thoreau penned in his journal. ‘Methinks that the moment my legs begin to move, my thoughts begin to flow.’ Thomas DeQuincey has calculated that William Wordsworth — whose poetry is filled with tramps up mountains, through forests, and along public roads — walked as many as a hundred and eighty thousand miles in his lifetime, which comes to an average of six and a half miles a day starting from age five.

“What is it about walking, in particular, that makes it so amenable to thinking and writing? The answer begins with changes to our chemistry. When we go for a walk, the heart pumps faster, circulating more blood and oxygen not just to the muscles but to all the organs — including the brain. Many experiments have shown that after or during exercise, even very mild exertion, people perform better on tests of memory and attention. Walking on a regular basis also promotes new connections between brain cells, staves off the usual withering of brain tissue that comes with age, increases the volume of the hippocampus (a brain region crucial for memory), and elevates levels of molecules that both stimulate the growth of new neurons and transmit messages between them.

“The way we move our bodies further changes the nature of our thoughts, and vice versa. … When we stroll, the pace of our feet naturally vacillates with our moods and the cadence of our inner speech; at the same time, we can actively change the pace of our thoughts by deliberately walking more briskly or by slowing down.

Because we don’t have to devote much conscious effort to the act of walking, our attention is free to wander. …

“This is precisely the kind of mental state that studies have linked to innovative ideas and strokes of insight. Earlier this year, Marily Oppezzo and Daniel Schwartz of Stanford published what is likely the first set of studies that directly measure the way walking changes creativity in the moment. They got the idea for the studies while on a walk. …

“In a series of four experiments, Oppezzo and Schwartz asked a hundred and seventy-six college students to complete different tests of creative thinking while either sitting, walking on a treadmill, or sauntering through Stanford’s campus. In one test, for example, volunteers had to come up with atypical uses for everyday objects, such as a button or a tire. On average, the students thought of between four and six more novel uses for the objects while they were walking than when they were seated. …

“Where we walk matters as well. In a study led by Marc Berman of the University of South Carolina, students who ambled through an arboretum improved their performance on a memory test more than students who walked along city streets. A small but growing collection of studies suggests that spending time in green spaces — gardens, parks, forests — can rejuvenate the mental resources that man-made environments deplete. Psychologists have learned that attention is a limited resource that continually drains throughout the day. A crowded intersection — rife with pedestrians, cars, and billboards — bats our attention around. In contrast, walking past a pond in a park allows our mind to drift casually from one sensory experience to another, from wrinkling water to rustling reeds.”

Even when I take my walk in the house on a bad day in winter, I find that walking helps me think. My pace indoors or out is not very energetic, but I like that all sorts of ideas and memories pop into my head as I walk.

At the NY Times blog called “Well,” Gretchen Reynolds describes new research that ties walking to creativity.

“A brief stroll, even around your office, can significantly increase creativity, according to a handy new study. Most of us have heard by now that exercise, including walking, generally improves thinking skills, both immediately and in the longer term. …

“Similarly, exercise has long been linked anecdotally to creativity. For millenniums, writers and artists have said that they develop their best ideas during a walk …

“Researchers at Stanford University recently decided to test that possibility, inspired, in part, by their own strolls. ‘My adviser and I would go for walks’ to discuss thesis topics, said Marily Oppezzo, at the time a graduate student at Stanford. ‘And one day I thought: “Well, what about this? What about walking and whether it really has an effect on creativity?” ‘

“With the enthusiastic support of her adviser, Daniel Schwartz, a professor in the Stanford Graduate School of Education, Dr. Oppezzo [gathered] her volunteers in a deliberately dull, unadorned room equipped with only a desk and (somewhat unusually) a treadmill, Dr. Oppezzo asked the students to sit and complete tests of creativity … Then the participants walked on the treadmill, at an easy, self-selected pace that felt comfortable. The treadmill faced a blank wall. While walking, each student repeated the creativity tests, which required about eight minutes.

“For almost every student, creativity increased substantially when they walked.”

The study was published this month in the Journal of Experimental Psychology: Learning, Memory, and Cognition.

New research featured at WBUR radio’s “Only a Game” suggests that frequent physical activity in school boosts learning.

“Mid-morning on Tuesday at the South Lawrence 5th Grade Academy in Lawrence, Mass., a row of students prepares to learn science more efficiently…by stepping.

“At this kind of school within a school, the daily schedule for these fifth graders includes not one physical education class, but three. The students break during the day for physical activity, which, according to Kevin Qazilbash, the school’s principal, is not to say academics are being de-emphasized.” More.

“The curriculum at the South Lawrence 5th Grade Academy is based in part on the notion that exercise improves brain function and stimulates learning. According to Dr. Majid Fotuhi, the Chairman of the Neurology Institute for Brain Health and Fitness in Baltimore, studies support the idea that exercise can improve learning efficiency for children. …

“ ‘It’s so exciting,’ Fotuhi told Bill on … Only A Game. ‘There are actual new cells that are born in the memory parts of your brain. Literally, new cells are born, this has been shown in animal studies. So exercise is the best thing for [the] brain, especially for the memory part of the brain.’ …

“Though no study prescribes a perfect amount of exercise, Fotuhi offers guidelines to parents and educators.

“ ‘My recommendation would be at least one hour a day for children who are 6-12 and for high school kids, two hours a day,’ Fotuhi said. ” More.

I myself find that walking around helps me think, and I remember my father doing that, too. He was a writer. There is something about moving around while puzzling out how to express a complicated thought that is more productive than sitting in front of a computer (or in his case, a typewriter).

I love stories like this in any field, even a field as foreign to me as mathematics.

A mathematical puzzle that most experts didn’t expect to see solved in their lifetime has been quietly mastered by a professor in New Hampshire. He just got an idea and worked it out.

Carolyn Y. Johnson covers the story for the Boston Globe:

“A soft-spoken, virtually unknown mathematician from the University of New Hampshire has found himself overnight a minor celebrity, flooded with requests to give talks at top universities.

“On May 9, mathematician Yitang Zhang, who goes by Tom, received word that the editors of a prestigious journal, Annals of Mathematics, had accepted a paper in which he took an important step toward proving a very old problem in mathematics.”

He showed that there are “an infinite number of primes separated by less than 70 million. [It] excites mathematicians because it is the first time anyone has proved there are an infinite number of primes separated by an actual number. … News of the feat rippled across the math world.

“ ‘This is certainly one of the most spectacular results of the last decade,’ Alex Kontorovich, a mathematician at Yale University, wrote in an e-mail. ‘Many people expected not to see this result proved in their lifetime.’

“Zhang said that he began to think seriously about solving the problem four years ago. … The epiphany did not come to him until July 3 of last year, when he realized he could modify existing techniques, building on what others had tried.

“ ‘It is hard to answer “how,” ‘ Zhang wrote in an e-mail. ‘I can only say that it came to my mind very suddenly.’

“The mathematician lives a simple life that he says gives him the ability to concentrate on his work. … Zhang’s achievement shows what can be accomplished by the elegant instrument of the human mind, working alone.

“ ‘Keep thinking, think of it everyday,’ Zhang said he would tell himself. ..

“ ‘The old adage is that mathematics is a young person’s game, and moreover most of the top results come from people or groups of people known to produce them,’ Kontorovich wrote. “Professor Zhang has demonstrated not only that one can continue to be creative and inventive well into middle-age [he’s in his 50s], but that someone working hard enough, even (or especially) in isolation, can make astounding breakthroughs.’ ”

I love the reminder about the importance of time to think. Everyone needs time to think. Even people who are not solving math puzzles for the ages.
