This map depicts the location of the Large Hadron Collider built by the European Organization for Nuclear Research (CERN) beneath the France/Switzerland border. Kersting drew it at a pub in St. Paul, Minnesota over a discussion with friends at a local pub. A few days before the particle collider was set to be used for the first time, the group discussed the scientific experiments that would be conducted there. The references to “Cam” indicates the location of their mutual friend who lived in Switzerland at the time.
