Cheng is a mathematician, so she knows how to make an airtight argument. But even for her, logic sometimes falls prey to emotion, which is why she still fears flying and eats more cookies than she should. If a mathematician can't be logical, what are we to do? In this book, Cheng reveals the inner workings and limitations of logic, and explains why alogic--for example, emotion--is vital to how we think and communicate. Cheng shows us how to use logic and alogic together to navigate a world awash in bigotry, mansplaining, and manipulative memes. Insightful, useful, and funny, this essential book is for anyone who wants to think more clearly.

    We never have to pass a test to get our Money License before we can take a new credit card for a drive. Most of what we learn about money comes from advertising or from other people who know as little as we do. No wonder we make such basic mistakes. No wonder we feel disempowered and scared. No wonder so many of us just decide to stick our heads in the damn sand and just never deal with it. I wrote this book, because so many of the people I spoke to told me that they wished someone would. In this clear and engaging basic guide to managing your finances, Sam Beckbessinger covers topics from compound interest and inflation to “Your brain on money”, negotiating a raise, and particularly local South African phenomena like “black tax”. The book includes exercises and “how-to’s”, doesn’t shy away from the psychology of money, and is empowering, humorous and helpful. The book you wish you’d had at 25, but is never too late to read.
