Aristotle's Wheel Paradox⭕🔘
The paradox:
▪️We have a circle and there is another circle with smaller radius. They are co-centeric.
▪️If circle make full turn without sliding, both smaller and bigger circle make full turn too. If we assume that the passed road is equal to the circumference of circles. We have got smaller circle's radius is equal to bigger one's.
⚫Unsatisfying Solutions I found:
◾"Do not assume that smaller circle's circumference is equal to passed road since the surface that contacts to the ground is bigger one. " // Okey but it does not explain the paradox, it explains just what is the wrong assumption (even does not explain why it is a wrong assumption.)
◾It is undeniable that every point on both smaller and bigger circle will contact exactly one and only one point on their path. Therefore we can think that this is a bijective maps and smaller circle is isomorphic to bigger one. (Okey but ....)
Question: What is the true answer? What is wrong with the definition of circumference of a circle and relationship with its taken path.
