The winning teams have arrived! The young physicists of Odysseus' Comrades and Dominicuscollege have arrived at CERN to start their adventure. Their first day was devoted to safety awareness and training. The teams learnt to recognize hazard signs and safety protocols at CERN, and members of the HSE department, Cryogenics group and Fire Brigade gave presentations about staying safe at CERN. Tomorrow the students will present their ideas for their experiments, and visit some of CERN's installations.
