The European Laboratory for Particle Physics (Conseil Européen pour la Recherche Nucléaire-CERN) studies basic sub-nuclear particles and the forces of matter in an effort to unlock the ultimate puzzles of the universe. CERN was formed in 1954 to reestablish Europe’s leading role in fundamental science after World War II. CERN has become the leading world research laboratory studying high energy physics. The scientists’ work is based on the use of powerful particle accelerators and colliders to probe the atomic constituents and the forces that hold them together. The scientific work at CERN has also lead to many novel developments in computer and telecommunication applications. In particular, the World Wide Web was conceived at CERN in 1989.
