The LHC (Large Hadron Collider) and our daily Physics

The goal of this article is to introduce some physical concepts used in the largest particle collider in the world (LHC) and demonstrate that this equipment does not offer any risk to Earth. These concepts will be treated from content covered in high school, thus serving as an incentive to teaching practices in the basic Physics teaching. Topics covered will be: cosmic rays, mini-black holes, magnetic fields, particle detectors, luminosity, Higgs particle, RF (radio frequency) cavities, energy stored in different ways and the Standard Model of elementary particles. The calculations presented here are only approximations because, in most of these, were disregarded relativistic effects.
