The Cern facility has been intimately involved in the development of computing and the internet. BBC science and technology reporter Jonathan Fildes explains why.
In 1989 a computer scientist sat at his desk in a laboratory on the French-Swiss border and changed the world.
He invented a computer system to allow jobbing physicists working on a newly built particle accelerator to easily swap data amongst themselves.
The system quickly morphed, exploding into what is known as the world wide web.
Now a team at the Cern laboratory is at it again. This time, however, rather than just allowing scientists to share information, they have built a system that will also allow them to share computer power.
