Alice in Wonderland and Math(?!)

I came across a book called "The Universe in a Handkerchief" the other day. This book is about the works of Charles Lutwidge Dodgson, better known as Lewis Carroll, whom it turns out was a math instructor and loved math puzzles including logic paradoxes and word play among other things. (Where have I been?) I am fascinated so far at all the layers of humor and complexity included in the Alice in Wonderland books. There is much more there than the casual reader may realize. Many teachers have used the Alice stories to teach language arts, but it appears there's plenty there to teach some critical thinking, logic, and possibly even some math. Can't wait to read some more.
