Coin rotation paradox: Roll one coin around another coin of the same size, and it makes two full turns in a single lap, not one. That's because its center travels a circle twice as big as the coin's own edge. The arrow tip traces a cardioid, a heart-shaped curve with its point where the coins touch.
