“The tracks we’re seeing are beautiful”

Beams of protons started circulating again on Friday at the Large Hadron Collider at Cern. And the first low energy collisions have begun! From the Cern press release.

“It’s a great achievement to have come this far in so short a time,” said CERN Director General Rolf Heuer. “But we need to keep a sense of perspective – there’s still much to do before we can start the LHC physics programme.”

Also from the Cern press release, some of those beautiful tracks.
