Other suggested reading...

Can't remember where I was or who gave me this list of interesting reading, but I think it's a composite of a bunch of 'em:

Flatland -- Abbott
The Penguin Book of Curious and Interesting Numbers -- Wells
The Animal Family -- Jarrell
Robots Have No Tails -- Kuttner
Fantasia Mathematica - Fadiman
Titus Groan -- Peake
The Compleat Enchanter -- deCamp & Pratt

Of these books, I've only read Flatland. It was scrumtralescent.
