Comparing this site to Veritasium seems unfair to me. I don't see any evidence that this site generates direct revenue. I also think it's an excellent exercise in pedagogy. The best professors and brightest colleagues I remember from college - or, since you said "maths" I guess I should say "university" ;) - demonstrated extreme facility with the physical concepts and regarded their mathematical representations only as a useful tool to characterize them and communicate about them, not an end to themselves.

Maybe this is just personal preference. I knew capable students who were wrote and prescriptive in their approach to the courses, but I was closer to those who played in the conceptual end of the pool.

I once made a resource like this site for my own educational benefit when I was grappling with MR physics. You're right - I had to do the math(s)! - and came away with a much clearer understanding of the subject. Still, I received lots of correspondence from students and professors who found the visual aid helpful on their journey.

All combined, he may get a few thousand dollars per article, which I admit is not much for what we get, and certainly not enough to make a living.
