A wonderfully readable adventure through the mathematic poetry of mapping. Dr Rowinska has created something really special, a book that celebrates the science and ideas behind the cartographic art with tales of everything fascinating, from criminal geography to ancient earthquake detectors. An essential guide that illuminates how much of our understanding of the world, the past, and indeed the people around us, is shaped by the mathematician and the mapmaker.
