Sadly many professors fall victim to the Curse of Knowledge. It doesn't help they need to follow a tight schedule and intuition isn't something you can develop in a single lecture. I suppose self-study and repetition is the most likely solution.
>The best math textbook (Theory of Algebra) I ever read had little sections about the person who revealed a particular subject, why they were studying it, and how the subject is used.
I've found the best type of books provide motivation for concepts, how they have evolved, etc.
Take Computer Science for example, many of its concepts were area of research for decades but from a student's perspective it seems these concepts were always here instead of being constantly refined until the states they're now in.
