... In this light, one can understand the Dirac quantization condition for electric charge. We have seen that if monopoles exist, they are described by singular field configurations. This singularity is seemingly a gauge artifact. It can be chosen, for example, to lie in different directions by making ...

Geiger–Marsden experiment
The Geiger–Marsden experiment(s) (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where its positive charge and most of its mass are concentrated. They deduced this by measuring how an alpha particle beam is scattered when it strikes a thin metal foil. The experiments were performed between 1908 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester.
