FULL STORY

一个美丽的风景画,一个漂亮的钢琴sonata -- art and music are almost exclusively described in terms of aesthetics, but what about math? Beyond useful or brilliant, can an abstract idea be considered beautiful?

Yes, actually -- and not just by mathematicians, reports a new study inCognition.

Coauthored by a Yale mathematician and a University of Bath psychologist, the study shows that average Americans can assess mathematical arguments for beauty just as they can pieces of art or music. The beauty they discerned about the math was not one-dimensional either: Using nine criteria for beauty -- such as elegance, intricacy, universality, etc. -- 300 individuals had better-than-chance agreement about the specific ways that four different proofs were beautiful.

This inquiry into the aesthetics of mathematics began when study co-author and Yale assistant professor of mathematics Stefan Steinerberger likened a proof he was teaching to a "really good Schubert sonata."

"As it turns out, the Yale students who do math also do a statistically impressive amount of music," said Steinerberger. "Three or four students came up to me afterwards and asked, 'What did you mean by this?' And I realized I had no idea what I meant, but it just sounded sort of right. So, I emailed the psych department."

Yale professor of psychology Woo-Kyoung Ahn replied to Steinerberger and, after further discussion, gave him the name of a psychology graduate student with whom she thought he would get along.

Enter Samuel G.B. Johnson, study co-author and now an assistant professor of marketing at the University of Bath School of Management, who was still completing his Ph.D. in psychology at Yale when he connected with Steinerberger. Johnson studies reasoning and decision making. "A lot of my work is about how people evaluate different explanations and arguments for things," he explained.

Steinerberger said Johnson understood immediately how to design an experiment to test his question of whether we share the same aesthetic sensibilities about math that we do about other modalities, i.e. art and music, and if this would hold true for an average person, not just a career mathematician like himself.

"I had some diffuse notion about this, but Sam immediately got it," said Steinerberger. "It was a match made in heaven."

For the study, they chose four each of mathematical arguments, landscape paintings, and piano sonatas. Because the similarities between math and music have long been noted, Johnson explained, they also wanted to test people using another aesthetic modality -- art in this case -- to see if there's something more universal about the way we judge aesthetics.

约翰逊的研究分为三个部分。的玩家rst task required a sample of individuals to match the four math proofs to the four landscape paintings based on how aesthetically similar they found them; the second required a different sample to do the same but instead comparing the proofs to sonatas; and the third required another unique sample of people to independently rate, on a scale of zero to ten, each of the four artworks and mathematical arguments along nine different criteria plus an overall score for beauty.

They derived these criteria from "A Mathematician's Apology," a 1940 essay by famous mathematician G.H. Hardy, which discusses mathematical beauty. The researchers' nine dimensions elaborated from Hardy's six were: seriousness, universality, profundity, novelty, clarity, simplicity, elegance, intricacy, and sophistication. When Steinerberger and Johnson analyzed the ratings given by participants in part three, they found that for both the artworks and math arguments a high rating for elegance was most likely to predict a high rating for beauty.

的玩家nal step was to calculate the "similarity scores" for the participants in group three, which revealed how aesthetically similar they considered each proof and painting were to each other based on the separate beauty criteria. They then compared these scores to the results from the first group of participants, who were asked to simply match proofs with paintings based on their own intuitive sense of aesthetic similarity -- much like Steinerberger's initial analogy of the proof to a "good Schubert sonata."

When the results came in, Steinerberger and Johnson were surprised but pleased. They were able to take the similarity scores from participants in the third task to predict how the participants would behave in the first task. Participants in the third group agreed about which arguments were elegant and which paintings were elegant while, likewise, participants in the first group tended to match the argument the third group rated as most elegant with the painting they'd rated most elegant.

Laypeople not only had similar intuitions about the beauty of math as they did about the beauty of art but also had similar intuitions about beauty as each other. In other words, there was consensus about what makes something beautiful, regardless of modality.

"I'd like to see our study done again but with different pieces of music, different proofs, different artwork," said Steinerberger. "We demonstrated this phenomenon, but we don't know the limits of it. Where does it stop existing? Does it have to be classical music? Do the paintings have to be of the natural world, which is highly aesthetic?"

While quick to point out that they are not education scholars, both Steinerberger and Johnson see eventual implications of this research for math education, especially at the secondary-school level.

"There might be opportunities to make the more abstract, more formal aspects of mathematics more accessible and more exciting to students at that age," said Johnson, "And that might be useful in terms of encouraging more people to enter the field of mathematics."

"I think if you understand what people consider beautiful in math, then it could give insight into how people understand math in the first place and how they process it," added Steinerberger. "There's also the human implication of the question: How are we actually thinking about things as human beings? I think we have an obligation to collaborate with psychologists on this."
