Parent topics
- Cardinality [r]: The size, i.e., the number of elements, of a (possibly infinite) set. [e]
- Set (mathematics) [r]: Informally, any collection of distinct elements. [e]
- Set theory [r]: Mathematical theory that models collections of (mathematical) objects and studies their properties. [e]
Subtopics
- Infinity [r]: Add brief definition or description
- Natural number [r]: An element of 1, 2, 3, 4, ..., often also including 0. [e]
- Galileo's paradox [r]: The observation that there are fewer perfect squares than natural numbers but also equally many. [e]
- Hilbert's hotel [r]: A fictional story which illustrates certain properties of infinite sets. [e]
- Cantor's diagonal argument [r]: Proof due to Georg Cantor showing that there are uncountably many sets of natural numbers. [e]
