When one snooker ball hits another, both spring away from each other in an elastic manner. In the case of two photons a similar process -- the elastic collision -- has never been observed. Physicists ...

The quantum nature of interactions between elementary particles allows drawing non-trivial conclusions even from processes as simple as elastic scattering. The ATLAS experiment at the LHC accelerator ...

The game of billiards is an ideal sport to be tested with physics and mathematics. In many universities, professors use this game to explain some concepts about physics. The theory of rebounds and ...

Protons accelerated almost to the speed of light can collide similarly to billiard balls. However, since protons are quantum particles, from measuring such collisions we can learn unobvious things ...
