I enjoyed reading that. Maxwell's equations in differential form is the most elegant equations that I saw in my life. I remember in my freshman year I had 8 questions in my EM final and the last question was name four equations that you can use to solve all the other 7 questions. It was a straight question for free grade obviously. But I was puzzled that I could not actually derive all of what I used. I went on and submitted the exam and returned to my seat. I went on with deriving all of them and spent a couple of hours. I left the room being a physicist from that moment until now.
