How to Construct a Dodecahedron

How the greeks constructed the Dodecahedron. Euclids Elements Book 13, Proposition 17. In geometry, a dodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid. A regular dode

Gleaming the 5D Hypercube

In this short, we show how to think about the four dimensional and five dimensional hypercube. Even though we don't have these dimensions to visualize, we can give an idea of these objects in three dimensional space by the analogy learned from building lines, squares and cubes from smaller
