A related idea I love is Tim Chow's idea of "solving a previously unsolved expository problem". With enough effort & imagination I believe we can make great progress on these problems even for such supposedly hard subjects as quantum field theory, rocket science etchttps://twitter.com/karpathy/status/1038476966997852160 …

Which domains do you think most embrace the idea that refining exposition is as worthy of one’s time as extending the boundary of knowledge? E.g. my impression is that math (folks like Tim Chow aside) is leagues behind physics and CS in this respect.
None, AFAICT. I don't think physics does particularly. Things like the Feynman lectures are often treated as outliers - valuable, but not really part of what a physicist does, another example of F's eccentricity.

In some sense, this is why I started https://physicstravelguide.com . It’s an expository wiki where everyone can help to refine how we explain physics concepts.

Great work! I wish there was also a visual map to see how different concepts relate - such that you click on a node and it shows you different levels of explanation.

Well to me The Mechanical Universe is still one of the best examples of exposition of ideas, probably because of many great people working well together. We also have Walter Lewin as another example of caring *a lot* about exposition

I think that VR can have some positive impact here. Of course a medium can't get anywhere without the right people mastering how to use it, but I think it offers interesting novel opportunities. E.g. VR Academia (which is targetted to Japanese audience only tho)

To explain well, one has to be good at two things: 1) explaining, and 2) subject matter. It's hard to be good at one thing. How much harder is it to be good at two things?

Many professors/teachers across disciplines aspire to find better explanations for concepts all the time.
