There is in fact no duality involved, unless you try to describe the world in classical physics. But classical physics is just an approximation of quantum physics, which describes this phenomenon by the same rules that it explains phenomena we consider normal. As the guy says, "this is normal because it's quantum physics". Feynman gives an easily approachable introduction to Quantum Electro Dynamics in these lectures: http://vega.org.uk/video/subseries/8 http://vega.org.uk/video/subseries/8
