Purpose & methods of Large Hadron Collider explained

The LHC gets turned on this Wednesday, the last I heard. And some people think it will cause the planet to blow up. Not so says Professor Brian Cox in the YouTube video below. About the LHC's goals, from Wikipedia: "When activated, it is theorized that the collider will produce the elusive Higgs boson, dubbed the "God Particle"[6], the observation of which could confirm the predictions and missing links in the Standard Model of physics and could explain how other elementary particles acquire properties such as mass."
