Mr Panagiotis Charatzopoulos, Science teacher at our school, participated in the Seminar organised by the Hellenic Phycisists' Society in collaboration with scientists from CERN. The seminar took place in Geneva, at the CERN laboratory from 25 to 29 September 2010. In his own words: ?We had the opportunity to meet the CERN scientists who work in the sector of high end technology research, to benefit from communicating with them, to visit the laboratories where innovative research is being put into practice and, finally, to feel once more the superiority of the Sciences and the attraction of the perpetual adventure of discovering the hidden secrets of Nature through scientific research.?
