Click reports from the European Organization for Nuclear Research (CERN) in Switzerland. They've got some great access to the more restricted parts of the facility; from the control rooms where physics control the particle accelerators, to the 27km of tunnels buried underneath the Swiss/France border containing the Large Hadron Collider, and finally some really amazing shots inside the CMS Experiment, which is a huge 14m high experiment used to smash particles together and record what happens.
