But even better than this is that every day between 12 p.m. and 2 p.m., free of charge, the CERN cafeteria comes with several thousand scientists and engineers, and these guys basically know the answers to everything.
Mieux encore, tous les jours entre midi et 14h, plusieurs milliers de scientifiques et d'ingénieurs envahissent la cafétéria du CERN et répondent gratuitement à quasiment à tout.
