CERN visit

June 28, 2016

Last week OIS Y12 Physics and Chemistry students and two Y10s had the opportunity to visit CERN: The most important Physics institute of the world. CERN is a place full of knowledge, excitement and history. It was founded after 2nd World War with the goal of using Physics for peace. Scientific staff from more than 100 countries from all around the world research there in order to better understand our universe at its most fundamental level. CERN is an excellent example of international awareness and cooperation. Thanks to Paula and Luisa from the OIS administrative staff for the support on the logistics of this trip and to Mr. Alberto Soares for traveling with us!
