Edit: I took a look at some of the other books people recommended and they seem more advanced, this book is easier than them and probably better for someone without an EE background. I am not sure how to best learn electronics (I learned from The Art of Electronics, but that is probably not the easiest way to learn, and probably overkill for just learning how motors work.)
This was the book we used in undergraduate, It was quite readable as I remember.
TL;DR I think you vastly underestimate other fields of study because you've never looked into or considered them. I get that you're in awe of this particular page and want to express it, but be aware that you kinda come across as dismissive of everything that isn't electrical engineering or your own particular field of study.
And I'm sure other fields have this too, where to the outside it's "just atoms and molecules" and then the scientist chuckles and says "indeed".
