IPhO 2013 : Results

The 44th International Physics Olympiad took place in Copenhagen, Danemark, a country which provided to the scientific world many great physicists such as Hans Christan Ørsted, Tycho Brahe, Ole Rømer or Niels Bohr.

As usual, the competition was divided into two parts : five hours of theory, as well as five hours for the experiments. The three theoretical tasks involved many different fields of physics, often with a link to Danemark; the students had for instance to study some properties of a meteorite, and were asked to use their knowledge in order to understand how a plasmonic steam generator work, as well as the evolution of the Greenland ice sheet.

The experimental task was split into two experiments. The first one dealt with the velocity of light in different media (water, optic fiber), whereas the second one let them study the properties of solar cells under various conditions.


The following five candidates represented Switzerland (left to right):

  • Sven Pfeiffer, from Münsingen (Freies Gymnasium Bern, BE)
  • Alain Rossier, from Le Châble (Lycée-Collège de l'Abbaye, VS)
  • William Borgeaud, from Grandvaux (Gymnase de la Cité, VD)
  • Quentin Wenger, from Tramelan (Seeland Gymnasium Biel, BE)
  • Rafael Winkler, from Mettauertal (Alte Kantonsschule Aarau, AG)

Alain Rossier and William Borgeaud were both awarded with a bronze medal, Sven Pfeiffer, Rafael Winkler and Quentin Wenger each won an honourable mention. Great results for Switzerland !

Congratulations to the team for the extraordinary performance!
