Thing Explainer is such an appropriate title for this book. It is not a sit down and read it cover to cover kind of book. You could do that, but it’s not linear. I like it much better as a pick it up and learn about something book. Pick a point and see how (insert thing here) is explained in words everyone can understand. Fair warning – you may have to think about the words and the way they’re used to describe things. Do you know what a shape checker is? Fun, interesting and filled with detail. Fantastic book.
