One is rotated around the other without slipping so that it ends up on the opposite side of the other coin from where it began. It has made a single rotation, yet has only rolled a distance equal to half of its circumference. This can be visualised by placing two coins that are touching each other at one point flat on a table. Let both of them have the heads side up and be parallel to each other. Now keeping one coin stationary, rotate the other coin such that there is always one point of contact. Rotate until it reaches the opposite side. Now the coins will be again parallel to each other, contrary to our intuition. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coin rotation paradox」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
