ABSTRACT
I nd it hard to reconcile the beauty of this scene with what I know about the nature of light. is is part of the mystery of quantum reality.
Our world of large-scale (macroscopic) objects such as trees, bushes, and cricket balls is made up of small-scale (microscopic) things such as protons, neutrons, and electrons. e laws of physics that describe the large-scale world have been known and understood since the 1700s. We have known about the physics of the small-scale world since the 1900s. e problem is that the small-scale laws describe a way of behaving that, judged by the standards of everyday experience, is utterly bizarre. It is very
di cult to see how all the funny business going on at the atomic scale can lead to the regular, reliable world we spend our lives in.
