Flatland, by Edwin A.
You fall into the story (whose plot is by no means secondary to the mathematical ideas), and before you know it you find yourself in contemplation of things.
Abbott\'s charm lies in his ability to write simply and clearly about a topic that has its share of very unreachable, esoteric books.
The book is extraordinarily readable and succeeds even with people that are afraid of mathematics.
Abbot, is the must-read for anyone interested in getting a feel for higher dimensions.
