《数学思维训练报》有一篇文章,题目是《一张不能折九次的纸》,一下就把我吸引了。文中说,无论多大的一张纸,最多只能折八次。我心想:不可能,一张这么大的纸,连九次都折不了吗?我要亲手试一试!我随便拿了一张作业本大小的纸折了起来,前几次还顺利,折到第五次时,就只有一个瓶盖那么大了,连第六次都折不到。我拿来一块石头,使劲向纸 The Journal of Mathematical Thinking Training has an article titled “A piece of paper that can not be folded nine times,” and it drew me a moment. The article said that no matter how big a piece of paper, up to only eight fold. I thought: Impossible, a piece of paper, even nine times can not be folded? I want to try it myself!
