Droplet Explosion Explained
Swiss high school students are physics world champions
Five Swiss high school students won the gold medal at the Physics World Championships in Timisoara, Romania. They prevailed once morest Poland and Singapore.
The five students presented their solution to the “Droplet Explosion” problem at the “International Young Physicists’ Tournament” (IYPT). It is regarding the description of the phenomenon that a drop of a water mixture on the surface of an oily liquid can break up into smaller droplets.
The solution by Jan Kamm (Kilchberg ZH), Anja Christina Duevel (Forch ZH), David Fankhauser (Baar ZG), Chengjie Hu (Zürich) and Joel Tan (Ottenbach ZH) convinced the jury the most, allowing Switzerland to beat Poland and Singapore secured the victory, the association Pro IYPT-CH announced on Tuesday.
Before that, the team spent more than a year developing solutions to 17 physics problems. With these solutions, the five students initially prevailed once morest national competitors. At the international tournament, their results and conclusions were critically questioned by opposing teams in a discussion. The achievements were also graded by an expert jury. This qualified them for the final once morest Poland and Singapore.
At the tournament, teams from almost 30 countries meet once morest each other. Each country is represented by five students. (SDA)
