The birth of the Web | CERN
Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.

The Standard Model - CERN
The Standard Model includes the electromagnetic, strong and weak forces and all their carrier particles, and explains well how these forces act on all of the matter particles. However, the most familiar force in our everyday lives, gravity, is not part of the Standard Model, as fitting gravity comfortably into this framework has proved to be a ...
Accelerators - CERN
Accelerators use electromagnetic fields to accelerate and steer particles. Radiofrequency cavities boost the particle beams, while magnets focus the beams and bend their trajectory.. In a circular accelerator, the particles repeat the same circuit for as long as …
Large Hadron Collider reaches its first stable beams in 2024
On Friday 5 April, at 6.25 p.m., the LHC Engineer-in-Charge at the CERN Control Centre (CCC) announced that stable beams were back in the Large Hadron Collider, marking the official start of the 2024 physics data-taking season. The third year of LHC Run 3 promises six months of 13.6 TeV proton collisions at an even higher luminosity than before, meaning more collisions for the experiments to ...
The Higgs boson - CERN
On 4 July 2012, the ATLAS and CMS collaborations announced the discovery of a new particle to a packed auditorium at CERN. This particle had no electrical charge, it was short-lived and it decayed in ways that the Higgs boson should, according to theory. To confirm if it really was the Higgs boson, physicists needed to check its “spin ...

What's so special about the Higgs boson? - CERN
The Higgs boson is that particle, and its discovery in 2012 confirmed the BEH mechanism and the Higgs field, allowing researchers to probe ever further in their understanding of matter. Measuring the properties of the Higgs boson in detail is crucial to exploring many outstanding mysteries in particle physics and cosmology, from the wild ...
Atomic flashback: A century of the Bohr model - CERN
Jul 12, 2013 · Bohr, one of the pioneers of quantum theory, had taken the atomic model presented a few years earlier by physicist Ernest Rutherford and given it a quantum twist. Rutherford had made the startling discovery that most of the atom is empty space. The vast majority of its mass is located in a positively charged central nucleus, which is 10,000 ...

A short history of the Web | CERN
The first page of Tim Berners-Lee's proposal for the World Wide Web, written in March 1989 (Image: CERN) Tim Berners-Lee wrote the first proposal for the World Wide Web in March 1989 and his second proposal in May 1990.Together with Belgian systems engineer Robert Cailliau, this was formalised as a management proposal in November 1990. This outlined the principal concepts and it defined ...
