Social History and Theoretical Analyses of the Economy of Ethiopia Book

This is another of my fav books on math that I've read this year. Assuming a minimal set of prerequisites (probably just that you know English and know how to count), this book introduces you to a variety of topics ranging from number theory, 2D and 3D geometry, topology, to chaos theory, probability and statistics, and more importantly, HOW THEY RELATE AND APPLY TO THE REAL WORLD. The complexity is fairly minimal; they emphasize more on making you think better and having fun during the process rather than making you manipulate complicated notation and jargon. The chapters are all more or less self-contained, so you can pick and start from a chapter that suits your tastes.

(A word of warning though - it's a huge book, nearly a thousand pages long. Took me nearly 11 months to finish it. 8, perhaps, if you exclude the days I didn't read it.)
