This book gives a glimpse of CERN’s activities and highlights various lesser-known facets of the Laboratory: facets that are nevertheless essential to carry out research in High Energy Physics. CERN is not only a prime example of excellence in research, technology and innovation, but also a genuine melting pot of diversity of competencies, and of humanity. Science and art have creativity and open-ended enquiry as a common denominator. This book shows how these two worlds, once clearly united but now perceived as separate, remain, in fact, manifestations of that same spirit of human enquiry.
