This is a review of the present status of particle physics and the main scientific goals in our work at the “High Energy Frontier” with specific emphasis on connections to Cosmology. Based on an extraordinarily successful Standard Model, our field is exploring the fundamental questions such as the nature of mass and the unification scheme which only a few decades ago seemed to belong mostly to the realm of dreams. Neutrino masses and oscillations, the key to CP-violation and proton decay are actively searched for at accelerators and underground experiments.
