I was disabused of such pretty quick when I realized I had to repeat the same exercise over multiple sessions to replace in the students' heads Aristotelian physics with Newton's 3rd law XD. At the same time, I learnt to design a better force diagram than displayed in the assigned textbooks (many of which I suspect were influenced by Feynman).. Which is kinda my point. That the status quo kinda suck doesn't mean the notation or examples can't be improved upon. It's heartening that we're entering a post-textbook age.. I wasnt so interested in scicomm up there because I suspect that the "slow" uptake of Yang's ideas had more to do with bad pedagogy
