Ancient Greek mathematicians – most notably Plato - classified solid shapes thousands of years ago. Since then, remarkably few geometric ‘solid’ forms have been discovered and the last collection was ...

Mathematicians present the Nopertedro: a Rupert property solid that broke an old myth by preventing one copy from passing through another.

The work of the Greek polymath Plato has kept millions of people busy for millennia. A few among them have been mathematicians who have obsessed about Platonic solids, a class of geometric forms that ...

You might not be able to solve Rubik’s cube, but now you can make one. The multicolored puzzle that’s kept small and big hands busy since the 1970s lost the final round in a fight to hold on to a ...

3D shapes can be made from 2D shapes called nets. Watch the video to learn how 3D shapes, such as a cube, can be created from nets, an arrangement of 2D shapes. Let's talk about nets. More ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...
