This book is a collection of essays about math. They are shorter than many of the other essays I’ve read and slightly more interesting though less deterministic [often the reader is left with things to think about rather than drawn to one conclusion]. This book was originally published in Portugal and reprinted in the US. I’m not sure what happened between there and here, but all the graphics in the book are jaggedy and weird, as if they were blown up from really small images. Not a huge deal, but fiarly distracting [and in some cases problematic] in an otherwise really nice looking book.
