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

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

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

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

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

A team of researchers has successfully built a strange four-faced pyramid named Bille that always lands on the same face—no matter how it’s thrown. This physical object, officially classified as a ...

A London-based dentist may have cracked a centuries-old mathematics puzzle hidden in one of the most famous anatomical ...

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

This geometric figure — first identified by dentist William Bonwill in 1864 — is formed by connecting the two points where ...

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 ...
