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.
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!
