Is Oleg Tchernyshyov Retarded?

-
I have been asking who uses Cantor's idea that sets that go to infinity all have the same cardinality. The only answer I have received sed that Dembski and marks used it but that claim was never supported.

Now Oleg the asshole retard has chimed in:

MOAR set hilarity from Joe.

No one uses Cantor's concept of cardinality with respect to countably infinite sets.

Lesssee...

In mathematics, a countable set is a set with the same cardinality* (number of elements) as some subset of the set of natural numbers. A set that is not countable is called uncountable. The term was originated by Georg Cantor.

*As defined by Cantor, of course.

More formally,

Quote

A set S is called countable if there exists an injective function f from S to the natural numbers N = {0, 1, 2, 3, ...}. If f is also surjective and therefore bijective (since f is already defined to be injective), then S is called countably infinite.

So, the term countably infinite was introduced by Cantor himself. It denotes a set that can be mapped bijectively onto natural numbers. That's Cantor's cardinality through and through.

Not one word on who uses it. It is as if Oleg is just a drooling retard. It is obvious that he is just upset because he cannot follow two lines heading in opposite directions.

Nice job Oleg.
