Flatland

I read the book and listening to the audio version of the book Flatland, by Edwin A. Abbott.
It is a story about a 2D (2 dimensional) universe where a square learns about a higher 3D (3 dimensional) world.
Great book I highly recommend it. The story is a great illustration that people can use to help them understand the strange 4th dimension. Of course, I am not talking about what some presume is Time. It has many names such as the spirit realm or hyperspace, where presumably ghosts, hyper-beings, spirits and other such things exist. I often find myself trying to explain the 4th dimension or hyperspace and end up feeling like the square in the book trying to explain 3D to flatlanders (2D beings) and being ridiculed.
One other funny thing. Edwin’s middle and last name is Abbott. That could be written Abbott2. Haha.
