IPhO 2015 : Results

The 46th International Physics Olympiad took place this year in the economic capital of India, Mumbai.

The participants faced two five hour-long exams. The first part consisted of an optical experiment. The students had to study the diffraction of a laser beam on a spring. The results they got was similar the results Rosalind Franklin got in 1953, He was able to show the double helix structure of the DNA with x-rays.

During the theoretical part of the exam the participants had to solve three problems. The topics of the questions were wide, original and a big challenge. The students had to study the Neutrinos emitted by the sun and the constructions of a nuclear reactor. Another topic was Hamilton's principle and its applications - for example that light always travels the shortest distance between two points.

Switzerland was represented by (from left to right):

  • Anian Altherr, from Arnegg/SG (Gymnasium Friedberg Gossau)
  • Linus Geiser, from Suhr/AG (Alte Kantonsschule Aarau)
  • Andrea Gebek, from Unterseen/BE (Gymnasium Interlaken)
  • Mattia Humbel, from Burg/AG (Alte Kantonsschule Aarau)
  • Kajo Krummenacher, from Kriens/LU (Kantonsschule Alpenquai Luzern)

The Swiss team performed really well at these competitions. Linus Geiser and Mattia Humbel both won a bronze medal, additionally Anian Altherr, Andrea Gebek and Kajo Krummenacher were decorated with a honorable mention!

Congratulations to all the participants not only for their individual results but as well for the great team performance!

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:
