And God said...

and all was light!*

*For the sake of clarity the equations above are the four of the most famous and important equations in all of Physics. They describe how the electric and magnetic fields relate to their sources,charge density and current density. As we all know, light is made up of oscillating electric and magnetic fields and these equations dictate how these fields work. So they did shed light on the world both literally and metaphorically. Get it?
