IPhO 2017 : Results

This year the 48th physics olympiad took place in Yogyakarta (Indonesia).

The competition was split into two five hour exams. The experimental part consisted of two experiments. In the first one the students used a laser to examine the index of refraction and the constant of diffusion of a salt solution. The second experiment was about a so-called PDL trap that can make graphite rods levitate. A PDL trap is constructed using two magnets arranged in a certain way. The participants had to measure different properties of the magnets and rods in order to figure out how to use this PDL trap as a seismograph and a tilt sensor.

In the theoretical part the students were given three challenging problems. The subjects included dark matter, the expansion of the Universe and - fitting for Indonesia - tsunamis and earthquakes.

  • Tamar Som, from Lengnau/AG (Kantonsschule Baden)
  • Pascal Isenring, from Rafz/ZH (Kantonsschule Zürcher Unterland)
  • Adrian Rutschmann, from Bülach/ZH (Kantonsschule Zürcher Unterland)
  • Henning Zhang, from Villigen/AG (Kantonsschule Wettingen)
  • Alexandre Pinazza, from Lonay/VD (Gymnase de Morges)

Our participants achieved great results. Adrian Rutschmann und Henning Zhang won a bronze medal, and Pascal Isenring, Alexandre Pinazza and Tamar Som received honorable mentions!

We would like to congratulate the participants. Not only for their individual success but also for the team's result!
