Now, hopefully, those of you who know anything about graph theory can look at that, and that will satisfy you that that can also do arbitrary 3D structure, and in fact, you know, I can now take a dog, carve it up and then reassemble it so it's a linear string that will fold from a sequence. And now I can actually define that three-dimensional object as a sequence of bits.
假如你懂得一点点的图论知识 不妨看看这里，你会感到很舒服 因为它还能演化为任意的三维结构 事实上，我可以绘画出一条狗 而后将其重新组合，使之成为一个线性的长串 它最后可以实现复制 我还能将三维的物体变成一串比特
