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

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

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 ...

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

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

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 ...

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