Meet Bille, the name given to the world's first monostable tetrahedron—a four-faced object that will always land on the same ...

A team of researchers has successfully built a strange four-faced pyramid named Bille that always lands on the same face—no ...

“Bille” is the first-ever monostable tetrahedron, or a pyramid-like shape with four triangular faces that has one stable ...

A tetrahedron is the simplest Platonic solid. Mathematicians have now made one that’s stable only on one side, confirming a ...

With the help of powerful computers, researchers discovered a four-sided shape that naturally rests on one side, and built a ...

Well, consider this: only a few months ago, space exploration company Intuitive Machines reported that a lunar lander had ...

For more than five centuries, Leonardo da Vinci’s Vitruvian Man has invited admiration but also bafflement. With its ...

From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and ...

A tetrahedron has a triangular base and three triangular sides that form a pyramid. Pairs of faces meet along edges to create “dihedral” angles, of which a tetrahedron has six. The new proof ...

Tetrahedral kites make for a great DIY project. Originally developed by Alexander Graham Bell, these simple kites can be built out of straws, fishing line and paper. The weight to sail area ...

Because of this, we know that for the tetrahedron, cube, octahedron, and icosahedron, there are no straight paths going from a vertex back to itself that don’t pass through another vertex.
