To iterate means to repeat, so an iterative process involves
repeating something many times.
Imagine some dough, Plasticine or Blu-Tack, something that can
be made into a strip then stretched.
We are going to take a length of this material, which we'll
regard as the unit length, and put a mark at some fraction distance
Now we are going to follow a procedure and see where our mark
The material is folded in the middle so that the bottom reaches
back to the top.
The material is now only half a unit in length and twice as fat,
so it is rolled out or stretched uniformly to become one unit in
Finally we'll note the new position of our mark.
