Nice seeing you on HN. I thoroughly enjoyed the No Bullshit LA and Maths & Physics books. I wish more books would include concept maps, I find them a very useful tool for understanding how things fit in the broader picture.

Yes, concept maps are the bee's knees.

I remember from my tutoring days how useful they were to organize the different concepts covered in each lesson: I would start with a blank sheet and make the student add concepts to it as the lesson progressed, then by the end of the lesson use the concept map to review what we learned. Specifically, I would ask them to explain in their own words each "arrow" which was a great way to uncover misconceptions and solidify the material.

Once I'm done with editing the current book[1], I hope to have time to work on making dynamic concept maps that you can click on and explore/zoom-in on. I feel it would be cool to jump between detailed view (concepts), intermediate scale (topics), and high-level view (subjects).
