The history of particles

Delve deeper inside the atom through the inventions and discoveries of 20th century physics.

The 20th century witnessed incredible inventions and discoveries as physicists delved ever deeper inside the atom. From the apparatus used to identify the first subatomic particle to the photograph that confirmed the existence of antimatter, Collider showcases some of the most significant objects from the history of physics.

The inception of CERN from the post-World War 2 vision to its first accelerator, the proton synchrotron (PS), which began operating on 24 November 1959.
