A Zermelo-Frankel axiom that posits a set of this size is minimally satisfied by the Von Neumann ordinal omega, and the aleph numbers describe the cardinality of sets of this size.
The Riemann sphere is formed by adding this point to the complex plane. A Zermelo-Frankel axiom that posits a set of this size is minimally satisfied by the Von Neumann ordinal omega, and the aleph numbers describe the cardinality of sets of this size. The number of integers is the "countable" sort, while the number of(*) real numbers is an "uncountable" type. Series that approach this value are said to be divergent, and irrational numbers have this many non-repeating digits. For 10 points, name this mathematical concept describing a quantity without limit.
