中文摘要
一个普通的立方体是一个常见的正多面体的例子:它有各种正方形面(顶,底,前,后,左,右),由几条边(其中12条)分开,这些边以特定的方式在八个角上相遇。通常,这样一个立方体会让人联想到一个非常对称和刚性的物体,即欧几里得的实现;但如果我们考虑一个橡胶复制品,那么我们可以想象以奇妙的方式扭曲和扭曲立方体,破坏它的对称性。尽管如此,立方体的“组合特征”将在这种破坏尝试中幸存下来;仍然有6个正方形面,12条边和8个角,像以前一样相互连接。
英文摘要
An ordinary cube is a familiar example of a regular polytope: it has various square faces (top, bottom, front, back, left, right), separated by several edges (twelve of them), which meet by threes in a particular way at the eight corners. Usually such a cube suggests to the imagination a very symmetrical and rigid object, i.e. a Euclidean realization; but if we consider instead a rubber copy, then we can imagine twisting and distorting the cube in fantastic ways which destroy its symmetry. Nevertheless, the `combinatorial features' of the cube would survive this attempt at destruction; there would still be 6 square faces, 12 edges and 8 corners, interconnected as before.
