@s_gruppetta what is insane to me, before I started college and really had to learn these relations, I had absolutely no idea what was actually going on. I fall over myself trying to shed light on this for other people now!
@brandonb_phy I think the intuitive understanding of such relations is not often fully appreciated by students (and maybe teachers) at secondary/high school
