NDSU students win bronze

Three physics students at NDSU received the equivalent of a bronze medal in the international University Physics Competition.

Senior physics majors Marne Johnson, Rugby, Brandon Johnson, Hazen, and Ahis Shrestha, a junior in physics and math from Nepal, dedicated a weekend to crunching numbers and formulating calculations for the contest. The students had just 48 hours to solve a physics problem involving three-point shooting in Olympic basketball, using math and physics to determine what initial ball velocities and spins would result in a successful shot from the three-point line, using international basketball rules.

It is the first time NDSU students participated in the competition since it began two years ago. During the contest, students work in teams of three at their home colleges and universities all around the world, analyzing a real-world scenario using the principles of physics and submitting a formal paper about their work.

Sylvio May, associate professor of physics at NDSU, said the competition was a good fit, since the problem was an application of classical mechanics, a class that all three of the students studied in fall semester. "I hope they like the intellectual challenge and the opportunity to work as a team on a problem that has no simple solution," May said.

The students said the competition benefited them in different ways. "I was surprised by the amount of heavy computation that can go into something as simple and intuitive as throwing a basketball," Brandon Johnson said. "I chose to partake in the competition because I wanted to test my current knowledge against a real life application. Through the competition, I learned some of the value of teamwork in physics," he said. "The time limit was intense, to say the least."

Marne Johnson said she participated because the competition sounded fun and challenging. "I would be working with classmates I knew and trusted, and it would be good exposure to real-life physics problems. I was surprised by the difficulty we experienced mathematically modeling a moving projectile," she said. "Physics such as this in such a short time window is stressful but exciting, because you know you have a deadline to meet."

The students also learned lessons in time management. "I received an extremely abbreviated lesson in typesetting and graphing in Mathematica," said Marne Johnson, who used the software program for the first time. "But it is the best program out there for writing physics and math papers, so learn I did."

Shrestha found the crash course in solving physics problems useful as well. "I am usually a pen-and-paper person, but because of the limited time, we had to use Wolfram Mathematica for faster calculations and, as a result, I ended up learning the convenience of computational methods while solving a problem," he said. "Of course, this was possible with the help and cooperation of Brandon and Marne."

The students spent most of a weekend in November doing calculations, covering everything from a three-point shot with nothing but net, to rim shot, bank shot, spin or no spin on the ball.

The NDSU physics team was among 77 teams from around the world, including China, Singapore, Mexico and the United Kingdom, that competed in the challenge. Of those com
