If an object goes from A to B it passes infinitely many points. How can the object pass an infinite number of points in a finite amount of time? If the object was at every moment (infinitley small time span) at a point (infinitely small distance), then how is motion possible? So that's the paradox of motion that mathematical thinking deals with. But then you got physics where when you go down in size you hit the quantum world. So what implication has physics for the paradox of motion? Is there no infinite small in physics, but small means quantum world here? ???
