My brother Garrin currently works at CERN collecting data for his PhD thesis and has been helping with many other aspects of the Large Hadron Collider (LHC) experiment since 2012. With his intimate knowledge of CERN, he led me on a private tour of the facilities while I was visiting him. He gave me the run-down on certain aspects of particle physics and life at CERN as we went through official tourist exhibits and actual laboratory facilities. We breezed through some displays while he went into quite some details (from my perspective) about how censors are used to detect particles created during a LHC collision.
The tour ended while having a coffee at the cafeteria’s terrasse with some of his co-workers. Although I didn’t always follow the conversation, it was really fun to enter the world of CERN for a day.
