Mathematicians create a tetrahedron that always lands on the same side
With the help of powerful computers, researchers discovered a four-sided shape that naturally rests on one side, and built a real-life version from carbon fibre and tungsten
Hungarian Geometric Discovery Could Revolutionize Spacecraft Design
A research team at the Budapest University of Technology and Economics (BME) has achieved a groundbreaking geometric and engineering feat: they’ve designed and physically constructed the world’s first monostable tetrahedron. Named ‘Bille’, this unique four-faced object always tips back onto the same face when placed on a flat surface. The invention could have real-world applications, especially in the design of stable landing systems for space m…
They designed and built a quadrangular body that always returns to the same side on a horizontal surface. One of the discoverers of the Gömböc also participated in the work.
Researchers at the Budapest University of Technology and Economics (BME) presented the world's first monostable tetrahedron at a press conference on June 25, which could bring a breakthrough in practical applications, including the design of landing units for space missions. The researchers named the body Bille.
