LHC exhibit expands beyond the visual

The touring Tactile Collider event explores new ways to access Large Hadron Collider science through touch, sound and live interaction. The world of particle physics is invisible to the naked eye, existing at a scale that's almost inconceivably small. Stacked on top of each other, a trillion protons--particles found in an atom's nucleus--would reach just 1 millimeter high. Physicists build tools to "see" this world, making it visible through data and charts. In a new project in the United Kingdo...
