WebIn mathematics, the cardinality of a set is a measure of the number of elements of the set. For example, the set = {,,} contains 3 elements, and therefore has a cardinality of 3. Beginning in the late 19th century, this concept was generalized to infinite sets, which allows one to distinguish between different types of infinity, and to perform arithmetic on them. WebNope. Two sets having the same cardinality is not the same as two sets having the same elements. @Cronus Then that is impossible. Proof: suppose f were a continuous bijection from R to [ 0, 1]. Let a = f − 1 ( 0), b = f − 1 ( 1), and suppose WLOG that a < b.

Georg Cantor introduced the concept of cardinality to compare the sizes of infinite sets. He famously showed that the set of real numbers is uncountably infinite. That is, is strictly greater than the cardinality of the natural numbers, : In practice, this means that there are strictly more real numbers than there are integers. Cantor proved this statement in several different ways.
