In 1884, Edwin Abbott published his novel Flatland, in which he described a two-dimensional word with two-dimensional people.1 The story is told from the perspective of the novel’s main character, a square. One day, he is visited by a being from a three-dimensional world, a ball. Being unable to understand and believe the existence of a third dimension, the ball tears the square out of its two-dimensional life and shows it Flatland from above. Upon returning from the third dimension, and wanting to tell his fellow flatlanders about it, the square is frowned upon and not believed.
