Say that we have a line $\left(0,0.5\right)$. I want a process that can split that line and half and move that half a bit, and then take half of that half and moved it and so on, so that by the end all the pieces of the line would still be within the region $\left(0,1\right)$. An example of such a series is to take half of the line and move it half its size: $(0, 0.5)$ $(0, 0.25)$, $(0.375, 0.625)$ $(0, 0.25)$, $(0.375, 0.5)$, $(0.5625, 0.6875)$ 1. Is there a name for such a series? (it is similar to a [cantor set][1], but not quite) 2. How does one prove that this set will never reach 1, no matter how many splits we'll make?
