CERN's supercollider | Brian Cox
http://www.ted.com "Rock star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings...
==========
This is the Large Hadron Collider. It's 27 kilometers in circumference. It's the biggest scientific experiment ever attempted. Over 10,000 physicists and engineers from 85 countries around the world have come together over several decades to build this machine. What we do is we accelerate protons -- so, hydrogen nuclei -- around 99.999999 percent the speed of light. Right? At that speed, they go around that 27 kilometers 11,000 times a second. And we collide them with another beam of protons going in the opposite direction. We collide them inside giant detectors. They're essentially digital cameras. And this is the one that I work on, ATLAS. You get some sense of the size -- you can just see these EU standard-size people underneath. ...
