Summary
| Description |
English: Visualisation of the coin rotation paradox for general coin radii: A coin of radius r rolls around one of radius R = 3r. In (1), if R is straightened out, the number of rotations (number of times the arrow points upward) is R/r = 3. In (2), as R has been restored into a circle, r makes an extra rotation, giving R/r + 1 = 4. In the limiting case when R = 0, r makes 0/r + 1 = 1 simple rotation around its bottom point. |
