Flatland
by Edwin A. Abbott
How can an entity limited to two dimensions understand the possibility of a third? Edwin A. Abbott's drone and its magnificent "romance of many dimensions" explore this riddle in the experiences of its protagonist, Square, whose linear world was invaded by the messenger Globe, who heralded the third dimension. Part geometry lesson, part social satire, this classic work of science fiction brilliantly manages to expand the imagination of all readers beyond "their own dimensional superstitions." If you're not a mathematician, your odds of reading any novels about geometry are probably slim. But if you're only reading one in your life, it should be at the top of your list. Flatland imagines a two-dimensional world inhabited by intelligent geometric figures who think their planar world is everything that exists. But one Flatlander, Square, discovers the existence of a third dimension and the limits of world assumptions about reality, and begins to understand the convoluted problem of higher dimensions. The book is also a highly entertaining satire on the differences in society and class in Victorian England.
