Sets With Cardinality of The Continuum
A great many sets studied in mathematics have cardinality equal to . Some common examples are the following:
- the real numbers
- any (nondegenerate) closed or open interval in (such as the unit interval )
- the irrational numbers
- the transcendental numbers
- the Cantor set
- Euclidean space
- the complex numbers
- the power set of the natural numbers (the set of all subsets of the natural numbers)
- the set of sequences of integers (i.e. all functions, often denoted )
- the set of sequences of real numbers,
- the set of all continuous functions from to
- the Euclidean topology on (i.e. the set of all open sets in )
- the Borel σ-algebra on (i.e. the set of all Borel sets in ).

Famous quotes containing the words sets and/or continuum:
“Wilson adventured for the whole of the human race. Not as a servant, but as a champion. So pure was this motive, so unflecked with anything that his worst enemies could find, except the mildest and most excusable, a personal vanity, practically the minimum to be human, that in a sense his adventure is that of humanity itself. In Wilson, the whole of mankind breaks camp, sets out from home and wrestles with the universe and its gods.”
—William Bolitho (1890–1930)
“The further jazz moves away from the stark blue continuum and the collective realities of Afro-American and American life, the more it moves into academic concert-hall lifelessness, which can be replicated by any middle class showing off its music lessons.”
—Imamu Amiri Baraka (b. 1934)
