I downloaded the book "Carry On, Mr Bowditch." Opened it and only took three breaks. It's a fun read for both kids and adults. But you won't learn any new math through it. However, it taught me a few things. The importance of math and how tiny errors in calculations can cost lives. In this case, the lives of sailors. That before GPS, sailors used the position of moon and stars to calculate the longitude. A bit of American history - why the US had to become a navy superpower. I learned a lot about sailing - logbooks, knots, starboard, stern, lunar navigation, sextant... and how dependent on the whims of the Wind shipping used to be. A bit about patience with people mentally slower than me in a given topic. The analogy used: Walking in the dark and hitting my leg against a chair. I'm angry and want to break the chair but it's not the fault of the chair. Also learned about book writing. One could teach a class represented by audience of a book in search of explanations they'll understand. And then use those for the book. The sentence "Math conquers all" might be a good summary for the book.
