WebbSuppose you consider just the subset of $(0, 1)$ that consists of numbers whose decimal representation does not include an infinite suffix of identical repeating digits. Even this subset cannot be placed into a bijection with the natural numbers, by the diagonal argument, so $(0, 1)$ itself, whose cardinality is at least as large as this subset, must … Webb16 apr. 2024 · From Real Numbers are Uncountable, $\R$ is an uncountable set.

Webb25 feb. 2014 · N² is much bigger than N, which is bigger than sqrt (N), which is bigger than log10 (N). Put N = 10^10. N² has 19 digits, N has 10 digits, log10 (N)=10. These values do no get closer as we approach infinity, they diverge more. It is useful to compare different infinites and they have set themselves up to fail. WebbCardinality of the continuum. In set theory, the cardinality of the continuum is the cardinality or "size" of the set of real numbers , sometimes called the continuum. It is an infinite cardinal number and is denoted by (lowercase fraktur "c") or . [1] The real numbers are more numerous than the natural numbers .
