SwissPhO 2015 - Results

Aarau - At the Swiss Physics Olympiad the best young talents in Physics were chosen. The competition took place the weekend of march 21st and 22nd. The 20 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 interesting experiments. To succeed they had to work patiently and precisely. For one experiment the teenagers had to find the cooling constant of a cup filled with warm water. They hat to interpret the results and draw conclusions about the three stages of the head transfer taking place.

The five gold medalists will form the Swiss team at the International Physics Olympiad 2015 in Mumbai, India. Additionally Linus Geiser and Mattia Humbel 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 Neuen Kantonsschule Aarau.

The final ranking of the SwissPhO 2015 is given as follows:

Rank Name Region Total (max. 120) Distinction Special Award
1 Geiser Linus d 63.6 Gold SSP-Award 1
2 Humbel Mattia d 62.7 Gold SSP-Award 2

Results SwissPhO 2014

Aarau - The final round of the Swiss Physics Olympiad took place on March 23/24 in Aarau at the Neue Kantonsschule d'Aarau. Twenty-five participants managed to qualify for the final round and were confronted to a total of more than six hours of exams. Their main objective was to be amongst the best five, which would mean a place in the Swiss team at the occasion of the International Physics Olympiad (IPhO), held in 2014 by Kazakhstan.

This year competition was pretty demanding and was a real challenge for most of the participants. In a theoretical part, the students were given many problems to solve, covering a large spectrum of physical topics, amongst them the mechanics of a yo-yo, the thermodynamics of helium or the not-so-intuitive concept of Poynting vector. Their experimental skills were also tested with two specific questions, one investigating the rolling resistance of a marble on various surfaces, the other one testing their comprehension of a motor.

The final ranking of the SwissPhO 2014 is given as follows:

Rank Name Region Total (max. 104) Distinction Special Award
1 Winkler Rafael d 65.2 Gold SSP-Award 1
2 Roos Barbara d 58.1 Gold SSP-Award 2
