On Flatland
Banchoff, Thomas F., William F. Lindgren, and Edwin A. Abbott. Flatland. Cambridge: Cambridge University Press, 2010. pp. 294. Paperback.
The first part is primarily a description of 2-dimensional society and, above all, a commentary on Victorian society. The second part deals more with dimensional geometry. While much of this is common knowledge today, it is still a fascinating read that forces you to think about how different dimensions actually function.
