Geometry and Graph Theory were two of my favourite topics at University. I particularly enjoyed solving physics mechanics problems using geometry proofs rather than writing a long list of equations whenever possible.
Shape—The Hidden Geometry of Information, Biology, Strategy, Democracy, and Everything Else—by Jordan Ellenberg was a particularly satisfying read despite my only understanding of about 60-70% of the material and skipping over the mathematical works and proofs in the book.
Shape covers recent and relevant topics, such as epidemics, the spread of infectious diseases, artificial intelligence, and democracy. The book’s final chapter explains how gerrymandering votes work in Republican states and how Republicans redraw the electoral maps whenever they take office to change the outcomes in their favour without facing legal consequences.
