CERN, the European Organization for Nuclear Research, is an international intergovernmental scientific organization that operates the largest particle physics laboratory in the world. Established in 1954 and located near Geneva on the France–Switzerland border, CERN is home to the world's most advanced particle accelerators, including the Large Hadron Collider (LHC), which is the largest and highest-energy particle collider. CERN's primary function is to provide the facilities and infrastructure needed for high-energy physics research, enabling scientists to study the fundamental particles that make up the universe and the forces acting between them. This research helps uncover what the universe is made of and how it works, pushing the boundaries of human knowledge in particle physics. The laboratory is famous for major scientific discoveries, such as confirming the existence of the Higgs boson in 2012. It also notably contributed to the invention of the World Wide Web. CERN has 24 member states, with thousands of scientists from institutions worldwide collaborating on experiments. Its mission encompasses research, innovation, international collaboration, and education, training new generations of physicists and advancing fundamental science for the benefit of all. In summary, CERN is a leading global center for fundamental physics research, known for its particle accelerators that allow scientists to explore the smallest building blocks of matter and the origins of the universe. It represents a major international collaboration in science and technology.
