In Flatland: A Romance of Many Dimensions—written by Edwin Abbott Abbott—readers are presented with a question. What if the world were flat? Well and truly flat, that is, with figures in place of humans as we would think of them. It takes this question, and pushes it further, asking about the natures of people, and society, as well as angles, lines, and the dimensions of space itself. It takes this question, and uses it to deliver insightfully political satire, and a surprising amount of mathematical education. - Summary by FlamboyantOtter
