Silver Medal for Young Physicists from the University of Bayreuth’s Student Research Center

A team from the TAO Student Research Centre (SFZ) at the University of Bayreuth has won the silver medal at the German Young Physicists’ Tournament (GYPT). Benjamin Graf from Hochfranken-Gymnasium in Naila, Elisa Schöps from Münchberg Gymnasium, and Daniil Schulgin from Graf-Münster Gymnasium in Bayreuth impressed the jury with their project on droplet formation—a phenomenon familiar from a leaking faucet. Their research was supervised by Prof. Dr. Walter Zimmermann, a physics professor at the University of Bayreuth, along with his team at the SFZ.

At the German Physics Championship (GYPT), held at the Physics Center of the German Physical Society (DPG) in Bad Honnef, the competition follows a format similar to an international scientific conference. The participants—high school students in this case—present their research in English and then face critical questions from competing teams and a distinguished jury. This year was the first time that Benjamin Graf, Elisa Schöps, and Daniil Schulgin participated in the tournament, and they immediately secured a silver medal. Elisa Schöps and Benjamin Graf were among the top twelve in the individual rankings and are now among the participants in a workshop taking place in Ulm at the end of March to determine which students will represent Germany as part of the national team at the 38th International Young Physicists’ Tournament (IYPT) in Lund, Sweden, from June 30 to July 5.

"Since 2014, the TAO SFZ has been the only location in Germany to consistently contribute members to the five-person national team," says Zimmermann. He adds, "This year’s silver medal win is another great achievement in fostering young talent in Upper Franconia and through the Student Research Centre Bayreuth. This success is also thanks to the dedication and encouragement of teachers at the students’ schools, as well as the commitment of our mentoring team on the Bayreuth campus: Berin and Tarek Becic, Niklas Brütting, Frederik Gareis, and Sebastian Friedl. Many of them were themselves successful in national and international physics competitions and are now passing on their experience."

The most frequently cited reason for participating in GYPT is the students’ enthusiasm for meeting like-minded young people and spending time together. "Their contagious curiosity and passion provide an excellent foundation for the next generation of researchers, and we must do everything we can to support them," emphasizes Zimmermann.

The final round of this year’s German Physics Championship took place from 7 to 9 March in Bad Honnef. A team from Berlin also received silver, while the gold medal went to Lörrach. The three winning teams have been invited by the German Physical Society (DPG) to an exclusive two-day guided tour of CERN in Geneva—the world’s largest particle accelerator facility. The GYPT’s internationally recognized talent development program is supported by the German Physical Society and financially backed by the Wilhelm and Else Heraeus Foundation. Additionally, numerous volunteers, including the 46 jury members in this year’s competition, play a crucial role in making the German Physics Championship possible.

The Research Project of the Bayreuth Silver Medal Team

The Bayreuth vice champion team investigated droplet formation at a nozzle. This phenomenon is commonly observed when a faucet is leaking or not fully turned off. While seemingly mundane, droplet formation is also of technological importance, for example, in inkjet printers. In the simplest case, droplets form periodically at regular time intervals. However, the time interval between droplet formations can also vary, alternating between shorter and longer gaps. In more complex cases, the detachment of droplets can follow chaotic patterns, or smaller satellite droplets may separate after the detachment of a larger leading droplet.

The silver medal-winning team conducted controlled experiments to analyze how these fascinating processes depend on the slow flow rate through the nozzle, its diameter, and the properties of the dripping liquid. Using a high-resolution camera, they captured the droplet formation process and convincingly described their findings to the jury using theoretical models.
