Ah – Flatland! One of my all-time favorite math books! In this classic story, Edwin A. Abbott introduces to you A. Square, a character who lives in a two dimensional world. In the story, A. Square comes to realize that his universe is actually part of a multidimensional universe beyond his own 2 dimensions.
This story is a great introduction into the concept of hyperspace. Written in 1884, it is a superb example of using analogy to make the reader understand more complex concepts – in this case the “multiverse”.
The story begins:
I call our world Flatland, not because we call it so, but to make its
nature clearer to you, my happy readers, who are privileged to live in
Imagine a vast sheet of paper on which straight Lines, Triangles,
Squares, Pentagons, Hexagons, and other figures, instead of remaining
fixed in their places, move freely about, on or in the surface, but
without the power of rising above or sinking below it, very much like
shadows–only hard with luminous edges–and you will then have a pretty
correct notion of my country and countrymen. Alas, a few years ago, I
should have said “my universe:” but now my mind has been opened to
higher views of things.
