Quanta on my mind

Abstract:
A fundamental experiment in quantum physics involves shining a beam of light at a barrier with two open slits. Some of the light gets through the barrier, forming an interference pattern on a screen. This indicates light has the property of a wave. Yet if you close one slit, leaving the other open, the light appears as just a single shaft of light built up photon by photon on the screen, which indicates that light has a particle property.
