In an outstanding performance at the 86th William Lowell Putnam Mathematical Competition , MIT's team once again took the top spot for the sixth consecutive year. MIT secured four of the five Putnam Fellows, who are the five highest-ranking students, and the Elizabeth Lowell Putnam Prize, which is given to a woman whose "performance in the competition is particularly meritorious."
The members of the winning team, consisting of junior Cheng Jiang, senior Luke Robitaille, and first-year Chunji Wang, were all awarded as Putnam Fellows alongside senior Zixiang Zhou, each receiving a $2,500 award for their performance. Notably, Robitaille is a four-time Putnam Fellow, having received the award for each year of his studies. For a second consecutive year, sophomore Jessica Wan was awarded the Elizabeth Lowell Putnam Prize and received $1,000.
Wan was also among the top 25 scorers, amongst 16 others from MIT: Warren Bei, Reagan Choi, Pico Gilman, Henry Jiang, Zhicheng Jiang, Papon Lapate, Gyudong Lee, Derek Liu, Maximus Lu, Krishna Pothapragada, Pitchayut Saengrungkongka, Qiao Sun, Allen Wang, Kevin Wang, and Yichen Xiao.
A legacy of success
"I was delighted to see how well the MIT students did on the Putnam exam this year, which reflects their hard work, talent, and enthusiasm," says Professor Henry Cohn , who led class 18.A34 (Mathematical Problem Solving) this year, also informally known as the Putnam seminar.
MIT's continued success in the Putnam competition stems from a variety of sources. Some of this is built on things like the seminar, where students get together to sharpen their skills by diving deep into tough problems and discussing solutions.
Cohn, a former participant in the Putnam, comments on the joy of teaching the seminar and seeing students' progress. "When you spend a semester watching students present solutions to difficult problems, you start to understand how they think," says Cohn. "It's exciting to see them apply their abilities to new, difficult problems."
Professor Bjorn Poonen , who also led the seminar in previous years (and is a four-time Putnam Fellow), describes it as an opportunity to hone a spectrum of skills in competition preparation. "Knowing how to explain things well is really important for doing well on the Putnam and for everything else, and for this it really helps to have experience communicating with others, which is what the problem-solving seminar is all about."
A shared passion for problem-solving
The students who take the Putnam thrive on all aspects of the competition, from the social to the exam itself.
"It's not a school day, and we still get to do math," Jiang describes his excitement for the competition. Indeed, getting to "do math" extends beyond formally sitting for the exam, to breaks and opportunities for discussion that are interspersed throughout the day. The students take each opportunity to come together as seriously as they do the competition, and it is this collective passion for problem-solving that builds a strong sense of community and brings students back year after year.
"The competition brings together hundreds of students from across campus representing many majors, years of graduation, and degrees of math contest experience, but what brings everyone together is a shared love of solving problems," Cohn says. "You can see this in the clusters of students who stay to discuss the problems long after the exam has ended. Mathematics can sometimes feel like a solitary pursuit, but at this level, collaboration is key."
Community complements the shared passion the math enthusiasts share for problems and puzzles. "You get a kind of satisfaction similar to when you get unstuck while doing a crossword puzzle and everything falls into place," Poonen describes his own experience solving Putnam problems.
Consistency in certainty
The competition is also an opportunity to see familiar faces. Robitaille recalls his experiences in high school math olympiads, and highlights the friendly atmosphere at the Putnam. "Throughout college, I have stayed close with people I met at competitions," Robitaille says. "There's the whole background of times spent together, not just on contest day."
An event for both community and challenge, the consistency and certainty of competition day is what brought Robitaille and Zhou back year after year. "Each time, you have a set amount of time to sit in the room and work on the problems," Robitaille says. "If you were the type of person for whom that would be a fun thing, like me, it's nice to have an opportunity to do it again occasionally."
"It's more fun than the real world, where everything is complicated," Zhou adds with a smile.
