Collisions and Collaboration: The Organization of Learning in the ATLAS Experiment at the LHC

After twenty-five years of preparation, the Large Hadron Collider at CERN, Geneva, is finally running its intensive scientific experiments into high-energy particle physics. These experiments, which have so captured the public's imagination, take the world of physics to a new energy level, the terascale, at which elementary particles are accelerated to one millionth of a percent of the speed of light and made to smash into each other with a combined energy of around fourteen trillion electron…
