FAQ

Where can the idea of the Gömböc be applied?
In case of many mathematical discoveries the route to applications often takes many years. Although the Gömböc is a very recent result, applications in biology and geology are already very promising. Some turtles have evidently developed Gömböc-like shells to facilitate self-righting. The theory behind the Gömböc may help to provide a useful, new classification for pebble shapes. Beyond scientific applications, the Gömböc aroused the interest of applied engineers.

Why is the Gömböc expensive?
Although the Gömböc has no moving parts, the geometry has to be manufactured to unprecedented precision: a Gömböc of 10 cm diameter has tolerances far less than 0.1mm. This precision presents a formidable challenge even to state-of-art precision technologies. Nevertheless, as more pieces are produced, we expect the price to drop.

Is there only one Gömböc shape?
No, there are infinitely many Gömböc shapes. However, the overwhelming majority of these shapes are extremely close to the shape of sphere. The Gömböc, which is available in our webshop, is special, because this is the first known, physically manufactured mono-monostatic self-righting shape in the world.

Does the behavior of the Gömböc depend on the size or the material?
In theory, it does not depend as long as the material is homogeneous. In practice the mass of the Gömböc plays a role: heavier objects have a better chance to overcome small surface imperfections.
