(Vancouver, BC) - On Tuesday evening, December 8th, thousands of physicists around the world cheered as CERN's Large Hadron Collider (LHC) smashed together subatomic particles at the highest energies ever reached by a man-made accelerator and the giant ATLAS detector observed the products of the record-breaking reactions whizzing through its sophisticated tracking devices.  Some of the loudest cheers were from Canadians who helped design, build, and commission LHC and ATLAS which are launching a new era of discovery about how the universe works.

"This is the breakthrough moment we have all been waiting for," said Rob McPherson, spokesperson and Principal Inv
