WebMar 7, 2024 · In mathematics, the Hilbert cube, named after David Hilbert, is a topological space that provides an instructive example of some ideas in topology. Furthermore, many interesting topological spaces can be embedded in the Hilbert cube; that is, can be viewed as subspaces of the Hilbert cube (see below).

WebMay 6, 2024 · Hilbert’s third problem — the first to be resolved — is whether the same holds for three-dimensional polyhedra. Hilbert’s student Max Dehn answered the question in the negative, showing that a cube cannot be cut into a finite number of polyhedral pieces and reassembled into a tetrahedron of the same volume. 4.
Webhilbert cubefill Hilbert's square filling continuous curve can easily be generalized to 3 (and more) dimensions. Begin with some curve, inside a cube, from the front-left-bottom corner to the front-right-bottom corner. Next scale the cube with the initial curve down by a factor 1/2 and make 8 copies of this. The 8 small cubes of course fit into the
