A 3D shape with regular polygonal faces, meeting at equal angles, is a platonic solid. There are five platonic solids, the tetrahedron, cube, octahedron, dodecahedron and icosahedron.

Photographs of 3D-printed shapes show soft cells derived from space filling polyhedra. Blue is derived from a truncated octahedron, pink is from a hexagonal prism and green is from a cube.

The reason the shape changes from 3D to 2D when you get to six triangles has to do with the number of degrees in an equilateral triangle. There are 60 degrees at each vertex of the triangle, so ...

Witness the ultimate magnet satisfaction with fascinating magnetic games featuring an octahedron inside a cube. Watch as powerful magnetic forces create mesmerizing patterns and shapes, delivering ...

The first type of solid shapes to be discovered are known as Platonic solids, which include the cube, the tetrahedron (a 3D form made up of four triangular faces), the octahedron (a 3D form made ...

These 3D shapes have a lot of symmetry, though not as much as the Platonic solids. Then, for a truly mind-bending journey, you might land on the concept of higher-dimensional symmetric shapes.

Sitting against a white, digital backdrop is a 3D, violet and cerulean octahedron smeared with pink brush strokes. The octahedron is an aural manipulator: If ...

By harnessing the self-assembling properties of DNA, researchers coerced a single strand of the genetic material to assume the shape of an octahedron.
