After three years of work, my book HOW NOT TO BE WRONG: THE POWER OF MATHEMATICAL THINKING comes out today from Penguin Press! It's about math. Also: baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, packing 24-dimensional spheres, what Facebook can and can’t figure out about you, the invention of calculus, and the existence of God. The book is available at Amazon, Indiebound, Waterstones, and (I hope!) your local bookstore. MetaFilter has been a fantastically useful resource for me in putting this together; partly because I can use Ask for my questions about statistical significance in different languages and stockpicking scams, but more importantly because I've learned so much about how to write about math for non-mathematicians from writing about math on MetaFilter!
