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.

出于对行星之间空间的好奇，他假设每个间隙都必须对应一个立：四、立方、、二十和十二。

Octahedral is when we're going to have six pairs of electrons coming off.

是指有六对电子脱落的情况。

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， 我们称之为， 因为如果你在这些运动关节之间画线，就会形成一个的形状。
