The BBC has created a pretty nice introduction to the Large Hadron Collider, the marvelous experiment where the protons should begin their revolutions (but not yet collisions) on Wednesday.
I chose these comments about the Grid (computing). But he also talks about CMS, Atlas, Alice, LHCb, Tunnel, Grid, and others. Videos, pictures, and words are included.
On Wednesday, at 9:00 a.m. Prague Summer Time, you should watch CERN Webcast with the first beam. The TV program (that you know from Strings 2008) is already broadcasting some stuff now. Enjoy.
Meanwhile, most of the media coverage (hundreds of articles) talks about the end of the world. What would you expect? Find "communication" in IQ in different fields. Only teachers and public administrators are lower. ;-) For example, what's your estimate of the IQ of Sarah? My estimate is 85.
