Last week I was in Geneva doing a talk at LIFT 2012, which I will post when it goes online. As part of the conference I was invited to tour CERN and the Large Hardron Collider. Despite a hungover 7AM wakeup I managed to make the train to CERN. What an amazing experience!!

This is the main testing facility for beam line tubes:
Here we see the control room for the Large Hadron Collider. SO COOL.
