这个问题能颠覆你的认知,折叠的次数非常有限,关键是,你很快就折不动了!
厚度2mm
折1次,4mm
2次,8mm
3次,16mm,难折了!
4次,32mm,不好折了!
5次,64mm
6次,128mm,折不动了!
7次,256mm
8次,512mm
9次,1024mm=1.024m,不用设备没法折了
10次,2.048m
11次,4.096m
12次,8.192m,这么厚的纸只能想象了
13次,16.384m
14次,32.768m
15次,65.536m
16次,131.072m
17次,262.144m
18次,524.288m
19次,1048.576m
20次,2097.152m
21次,4194.304m
22次,8388.608m,已经非常接近了!
23次,16777.216m。
只折23次,就远远超过8848m。
