In this lecture, the creator of Minute Physics video series is speaking of his own experience and preferences with the matter.
I remember him making a point about using written formulas, visualizations and analogies for explaining purposes that sounded something like "we don't have to explain/ teach science the same way it was first written down when discovered". For me, it resonated as a very important, fundamental idea about teaching/ learning in general. Now i can't remember if that was during this lecture or did he have a separate video about it. I'll look it up and add it as a separate link later.
