One of the most amazing things we discovered in science is that everything is made of small particles. It's the properties of these molecules, atoms, nuclei, and elementary particles that allow us to answer ­simple questions like: why is grass green? Or, why is the sky blue? But how small are these particles? And how did we discover them? And does the search ever stop? To answer these questions we have to step into a world of wonder and magic.
