Flatland A Romance of Many Dimensions

In this work about a land of two dimensions we have at once social satire, as pointed today as when it was written, and insights into theoretical science. The author, posing as a square inhabitant of Flatland, first describes his country. Then he tells of his visions of Lineland and Pointland, his trip to Spaceland, and his fate when he preaches the Third dimension in Flatland.
