This isn't just about math, it's about how to avoid thinking in the typical flawed manner in which we are inherently 'programmed'. Mathematical thinking is mainly about thinking logically and rationally. Very few are capable of this, which explains why so many are fodder for manipulation by advertisers, politicians, cable news, televangelists, etc. If you want to avoid being the typical useful idiot and victim of such people, reading this book is a good place to start.<br><br>One early and poignant example is Ellenberg's description of the Laffer Curve. Poor understanding of this concept has led to decades of redistribution of wealth (not from the top down but from the middle up!). Ellenberg doesn't offer any opinions on all this or even disparage the concept. He even points out what's right about it. But he explains it in a simple way that can be applied to other concepts. And so goes the rest of the book.<br><br>I would especially recommend it to those who DON'T like math...it could change your mind about that. I only wish I had been taught math in a similar manner, rather than just memorizing how to go through the motions of solving equations.
