At Valparaiso University, Ruyue Yuan has found a connection between math and music that might surprise most people.

“They’re both beautiful,” Yuan said.

Yuan has been playing the violin since she was 6 years old. She loves music. In fact, she enjoys studying all of the humanities, but she also has a natural gift for mathematics.

So when she followed in her father’s footsteps — he was a visiting scholar at Valpo in the early 1990s — and came to Valparaiso University from her native Hangzhou, China, she was excited she wouldn’t have to choose between her passion for math and her love of music. The interdisciplinary nature of her studies in Christ College — The Honors College allows her to pursue both a math major and her interest in the humanities. She’s also a member of the Valparaiso University Symphony Orchestra.

“I can’t live without playing,” she said. “Music is a part of me. I love really old baroque: Vivaldi, Handel, Bach. And also I just love really peaceful, royal music.”

As a violinist, Yuan has the opportunity to study one-on-one with Yuan-Qing Yu, an artist-teacher in Valparaiso University’s music department and a member of Chicago Symphony Orchestra who is also from China.

“Every year she and some other musicians perform in the Christmas Concert,” Yuan shared.

This year Yuan will get the chance to join her teacher for a performance at Orchestra Hall at Symphony Center in Chicago on Sunday, Dec. 8.

“It is always nice to work with the orchestra — the students are very eager to learn,” Yuan-Qing said. “Ruyue is a hard-working student who is always enthusiastic about learning. She has very high expectations for herself, and I really enjoy having her in my studio class.”

In fact, it’s Yuan’s professors who are making her time at Valpo so special. She said many have become a lot like a second family to her — which is important to her as an international student who is so far from home.

“My teachers not only teach me to play violin, they teach me to be a better person,” she said.

It was one of her mathematics professors — Associate Professor of Mathematics and Computer Science Lara Pudwell — who introduced Yuan to the beauty that math and music share.

“She offered me an opportunity to be on her research team, and it was fantastic,” Yuan recalled.

The team was studying combinatorics, a complicated field of math that Yuan found exciting. “It was really interesting to me because I get to play with those permutations and find the algorithms and enumerations. I had never really thought about math in that really magical way.”

Yuan learned that math, like music, gets at something universal. “I think the way we approach math, especially in upper level math, it’s about how you approach the truth. You can use your knowledge to get there.”

Finding the truth through math is something Pudwell works hard to impart to her students.

“There is a huge difference between the stereotypical calculations that happen in early math courses and the creative problem solving that takes place in higher level math classes and beyond,” Pudwell said. “Students who take advantage of the opportunity to do undergraduate research or who go beyond the minimum general education requirements get to experience that math is really all about creatively combining previous math results to develop new true results.”

Now Yuan can’t help but see math everywhere, including in the music she plays with the orchestra.

“Bach’s music is definitely like math,” she said. “You can see those patterns in his music within the rhythms and melodies and chords. It makes me want to explore the music in math more.”
