Love Song To Geometry - And A Look At How It Is Truly Everywhere. This is a mathematician showing just how prevalent geometry is in our every day lives - and why modern math classes tend to ruin it for most people. As a mathematics oriented person myself (got one math-derived degree, very nearly got two others almost at the same time, former math teacher, current active software developer), this was fairly easy to follow - Ellenberg mentions some advanced concepts without actually showing many of them, though there is more actual equations in here than some might like in a “popsci” level book. Thanks to Ellenberg's explanations of said equations and concepts, this should be an easy enough follow for most anyone. And he really does do a great job of showing how even advanced ideas really do come down to the most basic principles - just applied in particularly interesting ways. Indeed, the only real critique I have here is that when Ellenberg gets off the math specifically and into more political and social commentary - even when ostensbily using the math as a shield - it gets much closer to “Your Mileage May Vary” level. Overall, those moments weren't quite pervasive enough nor did they stray far enough from the central premise to warrant dropping a star, and thus the book maintains the full five stars that all books start with for me. Very much recommended.
