Hilbert Cube Stereogram by Gene Levine
I was not familiar with a Hilbert cube prior to seeing this new stereogram created by Gene Levine. It is named after the German mathematician David Hilbert, and even when I read the definition, I am still not exactly sure what it is. Here is how Wikipedia defines the Hilbert cube:
The Hilbert cube is best defined as the topological product of the intervals [0, 1/n] for n = 1, 2, 3, 4, … That is, it is a cuboid of countably infinite dimension, where the lengths of the edges in each orthogonal direction form the sequence .
Sounds confusing, doesn’t it? Stare at this image to see a 3D version of this very complicated concept.
