At the end of the Second World War, European science was no longer world-class. Following the example of international organizations, a handful of visionary scientists imagined creating a European atomic physics laboratory. Such a laboratory would not only unite European scientists but also allow them to share the increasing costs of nuclear physics facilities.In the beginning 1952, 11 countries signed an agreement establishing the provisional council – the acronym CERN was born. CERN is the European organization for Nuclear research and it’s considered the biggest particle physics experiment.
CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research - as a result, numerous experiments have been constructed at CERN following international collaborations. It’s located at geneva and scientists, engineers and students from 113 nationalities are hosted. 29 September of 1954 was the ratification of this organization by 12 countries in Europe. Several important achievements have been made during experiments at CERN with the most important the development of World Wide Web and recently in 2012 the Higgs Boson.
