<p>Achilles runs ten times faster than the tortoise and
gives the animal a headstart of ten meters. Achilles runs
those ten meters, the tortoise one; Achilles runs that
meter, the tortoise runs a decimeter; Achilles runs that
decimeter, the tortoise runs a centimeter; Achilles runs
that centimeter, the tortoise, a millimeter; Fleet-footed
Achilles, the millimeter, the tortoise, a tenth of a
millimeter, and so on to infinity, without the tortoise ever
being overtaken. . . Such is the customary version.

<!-- ... -->
The problem does not change, as you can see; but I would
like to know the name of the poet who provided it with a
hero and a tortoise. To those magical competitors and to
the series
<formula notation="TeX">$$
   {1 \over 10} +
   {1 \over 100} +
   {1 \over 1000} +
   {1 \over 10,\!000} +
   \dots

the argument owes its fame.</p>

<p>The volume of a
sphere is given by the formula:
