 (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.   21:28, 9 August 2012
