Infinity: Ordinal and Cardinal Numbers

Featured Replies

Well I know you guys closed out one of these but the concept is interesting. Ordinal numbers and cardinal numbers I know a bit but not everything and cardinal numbers are part of one of the most important math discoveries of the 20th century Paul Cohen's result on the continuum hypothesis. Any takers?

Takers to do what? The threads were closed because none of the participants of the crackpot variety cared about cardinals or ordinals and just wanted to spout rubbish about how they couldn't believe that infinity plus one is infinity, whatever that may mea to them.
