신문지 한장으로도 달나라갈수 있다면 믿으시겠나요??

신문지를 마흔 두번 접으면 그 두께가 지구에서 달까지의 거리가 넘는다는것을...

신문지 한장의 두께가 0.1mm이고 정확히 한번 접으면 0.2mm가 되고 두번접으면0.4mm세번접으면0.8mm가 됩니다.

마흔두번까지 접으면439804651114mm가 되므로 약 439805km가 되고,지구에서 달까지의 거리는 약3844000km입니다.

실제로 마흔 두번까지 접을수는 없겠지요...수학적으로 일뿐...;;

제 친구들한테 말해주니까 신기해 하더군요....

주위분들께 이런 이야기도 주고받으면 재밌더라구요...신기하구요...^^
