Yessss, and he condensed it all into only four equations; the cornerstones of electromagnetic theory.
It tickles me pink in a totally non-gay kind of way, that you chose to write about Maxwell.
As a fellow / descendant countryman of his, attending Uni in Scotland as an Electrical and Electronic Engineering undergrad, where he is still honored as something like the god of Electromagnetism, I should confess (Before someone else who might remember points it out), I spectacularly failed that particular exam three times, before finally passing it on the fourth attempt. The reason was because I refused to study exam pass papers with known answers; the standard technique of folk sailing through exams first time getting 90%+ pass marks, whilst obviously not knowing much about the subject. For me I had to feel like I really knew something about the subject, to be able to answer the questions from that, rather than just memorising pass-papers with simiilar questions and answering pre-scripted exam questions like a form-filling exercise. I could see it was a challenging subject, mostly misunderstood, and had every intention of immersing in it, progressing the boundaries of it one day, which I thnk I did later, patenting and licensing new planar transformer technology.
Needless to say, most folk I studied with avoided ever getting into conversation with me on the subject of electromagnetism.
Most of them actually went immediately to work in the financial industry, as far as I am aware, nothing much to do with electrical and Electronic Engineering, in which they obtained far higher marks in their degrees than I did.
Electromagnetism is a tough subject, but the personal rewards from genuinely knowing something about it, are second to none, imho.
I am really happy to see you seem to give it, and Maxwell, something like the credit they deserve.
