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.

Switzerland was represented by (from left to right)

  • 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!

SwissPhO 2017 - Results

Aarau - At the Swiss Physics Olympiad the best young talents in Physics were chosen. The competition took place the weekend of march 25th and 26th. The 28 finalists prepared themselves during the months since the Preliminary Round, tackling a wide range of Physics questions. One great opportunity was the training weekend that took place at EPFL. Everybody had a lot of fun exchanging ideas with other participants that are equally interested in Physics as they are.

The exam questions the participants had to solve were quite challenging. They had to show their knowledge and skills solving theoretical questions and and an interesting experiment. To succeed they had to work patiently and precisely. For the experiment the teenagers had to find the coefficient of friction of a string on a rod. They had to interpret the results and to show that the friction increases exponentially with the angle between the first and the last spot the string touches the rod.

The five gold medalists will form the Swiss team at the International Physics Olympiad 2017 in Yogyakarta, Indonesia. Additionally Julius Vering and Adrian Rutschmann were awarded with the special prize for the best junior physicist offered by the Swiss Physical Society. These prizes were handed over at the ceremony in the Neue Kantonsschule Aarau.

The final ranking of the SwissPhO 2017 is given as follows:

Congratulations to all the participants, especially to the first five of them who are thus taking part in the IPhO 2017 in Yogyakarta.

More detailed scores are available here: Switzerland, Liechtenstein

Additionally we encourage all the candidates to participate next year again. The experience you gained this year will definitely give you an advantage next year. Note that we are going to introduce a new preliminary round which will start around August 2017. More information will be published on our web page.

Results of the preliminary round 2017

The preliminary round of the SwissPhO 2017 took place on Wednesday, 18th of January. 73 students from all across Switzerland and Lichtenstein took part in the competition, which was held simultaneously in four different places: Bern, Zurich, Lausanne and Lugano.

Congratulations to the following 25 Swiss participants and the 4 students from Liechtenstein who qualified for the SwissPhO 2017. (The ranking has no significance for the SwissPhO.)
