DESCRIPTION:Ordinals were the last acquisition by the Mathematical Zoo for
  the Number House\, a donation by Cantor in the late 19th century. Unlike 
 naturals\, integers\, rationals\, reals and complexes they can be infinite
  as well as finite\, and therein lies much of their interest.  In this tal
 k I shall explain where they come from\, what they can do for you\, and wh
 y (despite their being infinite) you (a mere finite being) need to worry a
 bout them.
