Someone has apparently written a sequel to “Flatland”, the 1884 book by Edwin Abbott Abbott. I loved the original. It was recommended to me in high school by my Calculus teacher and I thought it was the coolest thing I’d ever read. It’s all about A. Square, who lives in a two-dimensional world on an infinitely large plane. In a vision he visits the worlds of one-dimension (a line of points always travelling) and no-dimensions (just a point). Then he himself is visited by a sphere, which takes him into Spaceland and shows him the possibilities of even more dimensions. Apparently the sequel, called “Flatterland”, features A. Square’s great-great-granddaughter, Victoria Line. She is shown “spaces with infinitely many dimensions, spaces with none, spaces with fractional dimension, spaces with finitely many points, curved spaces, spaces that get mixed up with time, and spaces that aren’t really there at all.” In other words she is invited to see the surfaces and worlds imagined by recent theoretical mathematics and physics. Awesome…
