UTC  Any line segment can be divided continuously ad infinitum At all times with each division the length of each part shortens by a half while at the same time the number of parts multiplies by two So how can an infinite number of parts make up a finite whole Because for every division the lengths of the parts are reducing as fast as the number of parts are increasing     There is not enough in sources for Zenos writings to fully justify saying that Zeno ever actually claimed that the sum of an infinite number of numbers is infinite  though he has been interpreted that way by some What is clear is that he thinks a task with an infinite number of steps cannot be completed     August
