      Feynman told wonderful stories about how his father nurtured his curiosity from a very young age. Every parent knows how insanely curious kids are and how they will repeat activities until they understand. What the educational "factory" system does is structure the joy out of learning. The curiosity gives way to metrics and criticism. The fire is extinguished.

    It's just a "proper" textbook. In the past they assumed a scholar would self-educate and wrote the books as such. The modern textbooks - dominated by a handful of publishers - are designed to sell collateral teaching material and to feed a specific Standardized Test definition of proficiency. It is clear when you compare the fluidity of the cadence of this book to the modularity and voids of a modern, often larger ($$$) textbook.

    When I was doing my electrodynamics course, I failed the first time, because the book we used was so bad. The teacher was pretty bad too. A typical researcher who was forced to teach as well.
    Then I got the Lectures in Physics by Feynman. I got an A on the second try. The way Feynman explains stuff in these books is amazingly easy to understand. He does not plaster the pages with formulas just to show how clever he is. He writes a lot of words to explain everything. Lots of examples.
    I wish I had this book when I was taught Calculus.
