With an analogous skill, we would be able to divine precisely which state of perfection (or imperfection) human beings are perpetually approaching, or which record time for running the one-mile race will always be approached but never actually reached. One of the biggest payoffs of mathematicians' skill with 25 FANTASIZING asymptotic limits has been a prodigious theory called the differential calculus, invented by Isaac Newton and Gottfried Leibnitz in the seventeenth century. This theory is useful for describing, in perfect detail, smooth-going changes of almost any kind.

We can even predict the exact numerical leaps between Cantor's stepping stones using a simple formula that was already known during his time. According to this formula, the number of subsets we can create from a finite set with x number of elements is " 2 multiplied by itself x times. " In symbols, the phrase in quotes is normally written 2x. Thus, in symbols, a two-element set has 2 2 (that is, four) subsets and a four-element set has 24 (sixteen) subsets. If Cantor had stopped after having defined his stepping stones, then he would have provided us with a well-organized, rational prescription for getting to, but not necessarily reach­ ing, an infinite set.

More precisely, from some point onward there is a vanishing difference between the shapes and sizes of the circles and polygons. The net effect of this is that the interminable nesting of figures tends toward a small circle that is concentric with the original circle. Using their skill with infinite series, mathematicians are even able to pre­ dict the diameter of this limiting circle-this unrealizable ideal, as it were-to be roughly V12 of an inch . With an analogous skill, we would be able to divine precisely which state of perfection (or imperfection) human beings are perpetually approaching, or which record time for running the one-mile race will always be approached but never actually reached.
