Flatland: A Romance of Many Dimensions, With Illustrations by the Author, A SQUARE. 2nd, Revised Edition (With Active Table of Contents) (English Edition)

Flatland: A Romance of Many Dimensions is an 1884 satirical novella by the English schoolmaster Edwin Abbott Abbott. Writing pseudonymously as "A Square", Abbott used the fictional two-dimensional world of Flatland to offer pointed observations on the social hierarchy of Victorian culture. However, the novella's more enduring contribution is its examination of dimensions, for which the novella is still popular amongst mathematics, physics, and computer science students.
