Recently, there has been an intense interest and curiosity about the CERN laboratory and about accelerator and particle physics thanks to the discovery of the Higgs particle. This interest is not misplaced, because particle physics and accelerator technology are very active and colorful disciplines, which live on constant innovation and which push the limits of science and technology. It is precisely for this reason that it is very important and useful for students, teenagers and everyone who carries the excitement of discovery inside them to get to know to this field aimed at finding the most basic building blocks of the Universe.
