From PhysicsCakes https://twitter.com/PhysicsCakes on Twitter: My office at @CERN is in the building where the web was born. The corridors are lined with wooden cupboards, each one filled with retro treasures! Every day from tomorrow until Christmas well be opening a door of the #CERNCorridorCupboardAdventCalendar - stay tuned! https://twitter.com/PhysicsCakes/status/1200708919468986368/photo/1 https://chirp.cooleysekula.net/attachment/62403
