Cardinal and ordinal numbers
Two sets are said to have the same cardinality when there is a bijection (1-1 correspondence) between them.
This is a good definition. However, one would like to have a concept "cardinality" (rather than "the same cardinality"), so that one can talk about the cardinality of a set.
The first... | {"url":"http://www.win.tue.nl/~aeb/at/ordinals.html","timestamp":"2014-04-21T10:02:54Z","content_type":null,"content_length":"7521","record_id":"<urn:uuid:a71c3288-dc07-4ea0-96e0-6104eebcf165>","cc-path":"CC-MAIN-2014-15/segments/1397609539705.42/warc/CC-MAIN-20140416005219-00253-ip-10-147-4-33.ec2.internal.warc.gz"} |

volume, and any other equations using pi. If pi has an infinite number
