At CERN, the European Organization for Nuclear Research, physicists and
engineers are probing the fundamental structure of the universe. Using the
world's largest and most complex scientific instruments, they study the basic
constituents of matter - fundamental particles that are made to collide
together at close to the speed of light. The process gives physicists clues
about how particles interact, and provides insights into the fundamental laws
of nature. Find out more on https:// home.cern.
