Abstract
In general, physicists are considered rather sober individuals. Only in exceptional situations can we observe collective emotional outbursts within their ranks. On July 4, 2012 such a moment had come! On that day, the European Nuclear Research Center CERN, headquarters of the largest and most powerful particle accelerator in the world, the Large Hadron Collider (LHC), announced that it had detected the Higgs boson , a particle that physicists had been seeking for decades as the last missing link in the Standard Model of particle physics .

Notes
- 1.
The fact that gravity, with all its relative weakness at short distances, acts effectively more strongly than the electromagnetic force over large distances is due to the fact that there exist no negative masses. The electromagnetic force is attractive and repulsive, depending on the sign of the charges. Thus, over long ranges, isolated charges are shielded by other charges, e.g., dipole clouds, which make the forces acting on them effectively shorter range.
