Being a feline bibliophile in a house full of books is rather edifying. Especially when my People buys books with lots and lots of pictures.
The Cartoon Guide to Physics, by Larry Gonick and Art Huffman, is a really good read for cats like me who don't know the first thing about science.
The helpful cartoons, in a "George Herriman meets Patrick McDonnell" style, helped me calculate the acceleration on that mouse-on-a-string toy that's hanging from the bathroom door. (At least until Greyscale sat on it.) Explained those bright shiny things called 'photons' that happen when a People throws a light switch. Oh, and quantum physics. Gotta have quantum physics.
(pushes scientific calculator off desk) Gravity is a lot of fun, too.
