There’s a great book by Randall Munroe who is the creator of xkcd, that
very science-oriented comic, and it’s called Up Goer Five. It’s a reference
to the Saturn Five rocket that took the Apollo missions into space. What
he is doing in that book is he explains all these very complicated concepts all the way from climate change to physical systems to submarines and so on, but he does it only using the 1000 most common words in the English language.
