Quarks are elementary particles and a fundamental constituent of matter. They combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.
CERN, the world's pre-eminent particle physics laboratory, hosts the world's highest-energy particle accelerator. CERN was also one of the first scientific institutions to confirm that the Milgauss watch could indeed resist magnetic fields of up to 1,000 gauss. #RolexOfficial
