Curious about the space between the planets, he hypothesized that each gap must correspond to one of the Platonic solids: the tetrahedron, cube, octahedron, icosahedron, and dodecahedron.

出于对行星的好奇，他假设每隙都必须对应一柏拉图立：四面、立方、八面、二面二面。

Yeah, we call it an octahedron because if you drew lines between these kind of kinematic joints here, it would create an octahedron shape.

是的， 我们称为八面， 因为如果你在这些运动关节画线，就会形成一八面的形状。
